system.enterpriseservices.dll error

I am running a web app on w2k3/IIS 6.0/ASP.net 2.0. This app runs fine on a different server. The error message I get is

Compiler Error Message:CS0006: Metadata file 'C:\WINDOWS\assembly\GAC_32\System.EnterpriseServices\2.0.0.0__b03f5f7f11d50a3a\System.EnterpriseServices.dll' could not be found

I have seen solutions to remove the "<identity impersonate="true" />" setting from the web.config file. That has not been helpful. Another solution was to delete the system.enterpriseservices.dll from C:\Windows\assembly. I have deleted the file, copied a new .dll, and that did not work. I have reinstalled IIS and ASP.Net 2.0 as well. So far, no dice. Any other ideas are greatly welcomed!

Hello AJ,

This may be a dumb question, but is the assembly in the GAC on the deployment server? If it isn't, you should be able to add it by running "gacutil /if System.EnterpriseServices.dll" using the 2.0 version of gacutil.exe.

HTH,
Clay

Clay,

Thanks for the response. I just got the problem figured out today.

The file permissions were screwed up. Users did not have read and execute permissions to this folder:
C:\WINDOWS\WinSxS\x86_System.EnterpriseServices_b03f5f7f11d50a3a_2.0.0.0_x-ww_7d5f3790

After I fixed that I got a similar error message as before but it mentioned a system.enterpriseServices.Wrapper.dll and found out that this file was missing
C:\WINDOWS\WinSxS\x86_System.EnterpriseServices_b03f5f7f11d50a3a_2.0.0.0_x-ww_7d5f3790\System.EnterpriseServices.Wrapper.dll

Now it is running like a champ!

AJ

System.IndexOutOfRangeException

I'm seeing the above error message appear on a web form. All the formcode-behind does is grab data from a SQL Server db (2005 Beta) andwrite it out in specfied controls.
The line that throws up the error is the following:
<code>
Line 150: txtCoDeath1a.Text = dtr("COD1a")
</code>
'Dtr' is simply a datareader that has been initialised previously. Iknow I should be checking for nulls in the db, but that isn't theproblem in this instant as the record I'm grabbing does have data forthe field 'COD1a'. It's of type nvarchar, length 150.
I've googled this error and have not found anything that seems directly relevant.
I'm using VB.
Any help much appreciated.

try putting this before your code

if dtr.Read then
dtr("COD1a")
end if

Sorry Chris, I should've posted more of my code.
I already have those lines in the code.
Any other ideas?

Try this

if not System.DBNull(dtr("COD1a")) then

txtCoDeath1a.Text = dtr("COD1a")

end if

Could you post more of your code? Are results coming back from the database? Is there a field called COD1a?

Thanks for the help guys, but I've located the source of theproblem. Very simple; I'd misnamed 'Cod1a'. Its actually 'CodIa'. Spotthe difference? Neither did I for a while!
<Sheepish> Sorry and thanks again.

system.IO.File.Exists doesnt working for file that is outside my virtual directory

hi

i have file browser control to select any file and a button to upload
file on my web page now when i select any file. now on click of upload
button i have check that file exist or no

if system.IO.File.Exist(file path) then
...
end if
now when ever i choose file system.IO.File.Exist(file path) return
false, but if i select file from my virtual directory then only it
return true.

so how to select file from any folder on my PC and chech that it exist
or notIt may have to do with the ASP.net user in IIS not having read
permissions on the directories?

Are you using an absolute path or a relative path to the file?

I'm trying to access the System.Net.Mail namespace in an ASP.NET application (not website) and it's not available. Any ideas why not?

It is available in a different web site project, but not in an application.

make sure that a reference to System.dll assembly is exists in your application.

system.net.mail - email sending no longer working

Hi,

Previously on my web app I had a contact page that would send an email to me with all the filled in values from the user. The email would be sent with the FROM address the user put in, so when I received it I could reply back to them. I had this working for years, and now all of a sudden it errors out.

I get the following error. Please note I was using System.Net.Mail, but changed to a component to try and debug.

I'm wondering what would cause this error to happen suddenly? Perhaps a configuration change in IIS ? What would be a good work around to this ? Is it possible to maybe email from my own domain, but specify a different ReplyTo address?

Thanks,
mike123

Hi Jeff,

Thanks for the lightning quick reply, but sorry I forgot to include this part. I have emptied the mail box, it is definately not full. Also to make sure it wasnt a server side mail problem I also tried sending to other email addresses that also were verified to not be full.

I was thinking it might have something to do with the relaying ? I can paste mail logs if that might help ?

Thanks again,

anybody have any other thoughts on this ?

much appreciated

System.Net.Mail & sending emails with line breaks

Hi,

When a client sends an email via a web form (text entered in a asp:TextBox server control), the email received has no line breaks, and it is displayed in one line. This has bad impact on email readability... How can one overcome this probelm?

Thank you,

Alon

If you are sending mail text in simple text format then you have to use System.Environment.NewLine to move rest text in next line.

SmtpMail.SmtpServer = "1.0.0.127";
MailMessage mm = new MailMessage();
mm.From = "bill@.microsoft.com";
mm.To = "job@.apple.com";
mm.Subject = "";
mm.Body = "line 1" + System.Environment.NewLine + "line 2";

Hi,

Thank you for your reply.

I forgot to metion that the mail is sent in HTML format:

mailMessage.IsBodyHtml =true;

Am I supposed to parse the user's message (the text in the TextBox control), chck for CRLF (or is it \n) and replace it with System.Environment.NewLine? Isn't there some standard way to send the email, as i is in the text box (multiline text box. It looks like a text area)?

Thank you,

Alon

Here is the modified code for HTML formated body

mm.Body = "line 1" + "<br>" + "line 2";

Rest of the code will remain same.

But how can I know where line1 ends and line2 starts? All I have is a string I get form TextBox.Text. From this string I cannot deduce where did the user hit return - it's a "flat" string.

A word about he context of this: this web form is a "Contact Us" page. The TextBox is a multiline text box, which serves as a free text input field.

Thank you,

Alon

As what Firoz said, you have to use the "<br />"

You will use the following code to replace each line in your textbox to break

Replace(textbox1.text, vbCrLf,"<br />")

HTH
Regards

Oooops, now I understand. It works. I thank the both of you.

System.net.Mail default smtp host

i was using the old system.web.mail classes. and try to sent emails with net.mail, but i get an exception: System.Net.Mail.SmtpFailedRecipientException was unhandled by user code Message="Mailbox unavailable. The server response was: 5.7.1 Unable to relay for bla@dotnet.itags.org.bla.bla" host property of SmtpClient must be set up! but what is default smpt host? is it "localhost"? i get an exception if i use it. thank u for ur advice

if i use this code it works for me (System.Web.Mail):

SmtpMail.SmtpServer =null;

SmtpMail.Send(mail);
because the name of the local SMTP server is used!!!!!!
WHAT NAME IS IT? how can i find it out?
i need the name to set the Host property of SmtpClient (System.Net.Mail).
thank u for ur advice

Hello.

I believe that you should use the classes SmtpClient and MailMessage to send your email message.

i still need ur help
Hello.
See if this helps:
http://www.developer.com/net/net/article.php/3511731

hi,

i m sorry but it has nothing to do with my question!

Hello.
not sure on what you0re after, but normally you use set that propertywith the name of the server. and you're the only one that know that...

Hi,
Did you find a solution to this problem...I am having the same problem. I use System.Mail.Net with the following code
SmtpClient client = new SmtpClient("localhost");
client.Send(message);
And get the following error
Mailbox unavailable. The server response was: 5.7.1 Unable to relay for abc@.
abc.abc
Many thanks for any help you can provide.

HOW TO FIND THE NAME OFdefault smtp server?

stWooE wrote:

HOW TO FIND THE NAME OFdefault smtp server?

- Ask your IT department
or
- Goto the computer where the SMTP service lives, and use either (1) The name of the computer or (2) the IP address of the computer
And as noted in my last post, if there is any sort of permissions/security set on the SMTP service, you'll need to allow your web server to "relay" mail through it, all of it is at that website i linked to
- i talk all the time about my local smpt server
- for sure, i have tried the name of my comuter and ip, i get the same error!
i can only send emails with the deprecated classes from the version 1.1
but thank u anyway

this problem disppears if I change the Relay properties to "All except the list below", however this is not an acceptable configuration. Any help from here?
Thanks in advance

Hi, i know this post is rather old but i've searched the forums and found this thread hanging around and i have exactly the same problem as the original poster and i was wondering if perhaps some1 could give me some insight as to how to solve this this time around.

What do i type in host?

tx in advance,

Me

It's an even older post now, and I spent ages finding an answer to this problem, which still doesn't clearly appear her. So here goes:

If you are using the SMTP server that is installed with IIS, you need to allow relaying for 127.0.0.1 (localhost) in the SMTP Server properties. This can be found on the Access tab at the bottom - Relay Restrictions.

Under "Select which computer may relay through this virtual server", "Only the list below" should be checked. If not, check it, as this will prevent spammers hijacking your SMTP server. Then click "Add" and add 127.0.0.1 into the IP address.

In your script, you may well have something like this:

SmtpClient client = new SmtpClient();
client.Send(message);

You now need to add the bold line below:

SmtpClient client = new SmtpClient();
client.Host = "127.0.0.1";
client.Send(message);

Hope This Helps.

system.net.mail network host cache?

I need to change the name of the mail server for my .NET application. I changed it in web.config and on the .aspx page that sends the message. However, I still get an error message saying that the remote name could not be resolved, and the error message has the name of theold mail server. I have tried rebooting the server, but still get the same error.

Does .NET save configuration settings somewhere other than web.config? Is something getting cached? Other ideas?

Are you running VS debugger or testing on IIS server?

You can delete all files in cache.

Do you use only one config file?

If you have BLL and DAL, sometimes you have also config files here.

Visit this?site.
http://www.systemwebmail.com/

As Johan said, delete your temporary files, and build your web site again

Thanks

Thanks for the responses.

JohanNL, this site is on an IIS server. There is only one web.config file for the site. I did not implement BLL/DAL.

JohanNL and e_screw - this is probably a dumb question - when you say to delete cache/temp files, do you mean the ones in c:\windows\temp? Or what is the correct location?

You need to clear the ASP.NET temporary files

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

System.Net.Mail vs System.Web.Mail

I want to use the new System.Net.Mail instead of the old System.Web.Mail.
I'm getting an error "Hot not specified" when I try to do my last two lines:
System.Net.Mail.SmtpClient SMTP = new SmtpClient();
SMTP.Send(Message); //Error happens here
But the thing is, in my old use of System.Web.Mail, I never had this
problem. Why do I HAVE to specify the host in the new version and I didn't
have to in the old?
AlexHi,
In oldversion when using System.web.Mail, the SmtpMail class automatically
uses the built-in mail service in Windows 2000. But in new version,
SmtpClient class does not use any default mail service. Hence when using
System.Net.Mail namespace, you need to specify the host.
SmtpClient mailObj = new SmtpClient();
mailObj.Host = "name of the host";
(or)
SmtpClient mailObj = new SmtpClient( "name of the host");
MailMessage mail = new MailMessage("x@.yahoo.co.in", "x@.hotmail.com",
"Testing", "Hello Everybody");
mailObj.Send(mail);

Sharmila

Thank you Sharmila for your input.
Hi Alex,
Thank you for your post.
Unlike System.Web.Mail, which was introduced in the 1.0 Framework,
System.Net.Mail is not built upon the CDO/CDOSYS libraries. Instead it is
written from the ground up without any interop. Thus, it is not dependant
upon on other COM libraries. Although some functionality has been removed,
the new System.Net.Mail namespace is much more versatile than the older CDO
dependant System.Web.Mail.
Other than Sharmila's input about specifying the server in code, you can
also config the Host, Credentials and Port properties for SmtpClient by
using the settings in the application or machine configuration files. For
example:
<configuration>
<system.net>
<mailSettings>
<smtp deliveryMethod="network">
<network
host="localhost"
port="25"
defaultCredentials="true"
/>
</smtp>
</mailSettings>
</system.net>
</configuration>
Hope this helps. Please feel free to post here if anything is unclear.

System.Net.Mail vs System.Web.Mail

I want to use the new System.Net.Mail instead of the old System.Web.Mail.

I'm getting an error "Hot not specified" when I try to do my last two lines:

System.Net.Mail.SmtpClient SMTP = new SmtpClient();
SMTP.Send(Message); //Error happens here

But the thing is, in my old use of System.Web.Mail, I never had this
problem. Why do I HAVE to specify the host in the new version and I didn't
have to in the old?

AlexHi,

In oldversion when using System.web.Mail, the SmtpMail class automatically
uses the built-in mail service in Windows 2000. But in new version,
SmtpClient class does not use any default mail service. Hence when using
System.Net.Mail namespace, you need to specify the host.

SmtpClient mailObj = new SmtpClient();
mailObj.Host = "name of the host";

(or)

SmtpClient mailObj = new SmtpClient( "name of the host");
MailMessage mail = new MailMessage("x@.yahoo.co.in", "x@.hotmail.com",
"Testing", "Hello Everybody");
mailObj.Send(mail);

Regards,
Sharmila

System.Net.Mail versa System.Web.Mail

Hi,
I am hoping to find out the differences between the
System.Net.Mail and System.Web.Mail.
Can some nice folks post the differences; or some urls which show the
differences?
Great Thanks
FrankHello,
in .NET 1.1, only the System.Web.Mail was available. This implemenation had
fundamental flaws. For example, attachment could only be added from files,
not from Streams.
The .NET 2.0 implementation is System.Net.Mail and is much more flexible and
has a richer featureset.
Best regards,
Henning Krause

Actually System.Net.Mail replaces System.Web.Mail, which is now marked
as obsolete.

It's only "obsolete" for the .Net Framework 2.0.
It's still supported in the .Net Framework 1.0 and 1.1.
The correct term when a class works in previous
versions, but not in a later one, is "deprecated".

Obviously, as System.Net.Mail doesn't exist in framework 1.x.

The class is marked as obsolete using the Obsolete attribute. The
correct term for a class marked as obsolete is obsolete. You can also
call it "deprecated" as some other systems use that term for the same thing.
An obsolete class is still working, it's only recommended that it's not
used. As the framework is supposed to be able to run code compiled for
previos versions, classes can't just stop working, at least not until
they have been obsolete for some version updates.

re:

There's conflicting info on that.
See :
http://msdn2.microsoft.com/en-us/li...system.web.mail(VS.80).aspx
That page says that the classes in the System.Web.Mail namespace have been d
eprecated,
but all its classes have been marked as obsolete.
The namespace is not obsolete. It's deprecated.
That's because it doesn't work in the current version but works in the previ
ous ones.
See:
http://en.wikipedia.org/wiki/Deprecated
"The deprecated feature still works in the current version of the software,
but it may raise error messages or warnings recommending an alternative prac
tice."
and
http://www.w3.org/TR/WD-html40-970917/convent.html
"A deprecated element or attribute is one that has been outdated by newer co
nstructs."
System.Web.Mail can be thought of as "obsolescent", but not "obsolete", sinc
e it still works.
Ymmv, of course.

Not at all. It's very simple. There is an Obsolete attribute. There is
no Deprecated attribute. You can mark a class as obsolete, but you can't
mark it as deprecated.

That is not correct. The classes still work in the current version.

I think that you are confusing this with something else. Just because
something is obsolete doesn't in any way imply that it would not work
any more.

thanks for your response. I checked my web.config and debug is set to

System.Net.WebClient.DownloadFile doesn't work with http attachments

Hi,
I have an aspx page at the web server that provides PDF documents for smart
client applications.
Here is the code in aspx page that defines content type:
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition",
"attachment;filename=test.pdf");
I tested the aspx page by using browser and it works just fine.
Now I need to receive that file by using the
System.Net.WebClient.DownloadFile. The problem is that DownloadFile method
returns the following exception:
"Unable to read data from the transport connection: The connection was
closed."
I tested the DownloadFile method to open a direct pdf file like the
following statement:
(new
System.Net.WebClient()).DownloadFile(http://localhost/test.pdf,"c:\\test.pdf
");
It works just fine.
How can I use System.Net.WebClient. DownloadFile to download http
attachments?
Any help would be apprecited,
AlanThe answer is in your question, but you may not recognize it.
An HTTP Request is for a single resource, identified by the URL of the
resource, or in the case of the WebClient, a URI plus a file descriptor. You
have an ASPX page that returns a file with a couple of special Response
Headers in it. Those Response Headers read:
Response.ContentType = "application/octet-stream";
> Response.AppendHeader("Content-Disposition",
"attachment;filename=test.pdf");
This header indicates that the client should prompt the client to make a
second request for the file descriptor specified (text.pdf), and that the
Content-Type of that file is binary.
So, what you have to do is read the Response Headers, and make a second
request for that file specified.

System.Net.WebException

Hi,
I am calling an external web service that returns some data which is being

The page works great for a few minutes and then all of a sudden throws the

Any help will be greatly appreciated.
Thanks!this is normal. it just a timeout on a page request. you need to decide how
to handle it. maybe save the last results and resuse.

Thanks for the quick reply Bruce.
Is it a timeout on the webpage that is calling the web service or is it a
timeout that is occuring on the web service? What does it mean when you say
"save the last results and reuse" ?
Thanks!
