You can create graphic images from any .NET code.
The question then becomes "what do you do with the image?"
In ASP.NET the most obvious thing would be to point an image control to it.
MyImageControl.ImageURL="myImage.gif"
or
MyIMageContro.ImageURL="myImageGeneratorPage.aspx"
I hope this helps,

System.ExecutionEngineException problem

I have a stable app developed on ASP.NET 1.1 that I'm porting to 2.0.
However, I've noticed that on one page, if I click a button to perform some
business logic (which runs fine), then click on a hyperlink to move to a
different page, I get a 'System.ExecutionEngineException' exception. There
is no line highlighted in the debugger.
I'm not using interop or other threads.
Event viewer shows:
.NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3)
(80131506)
I also sometimes see:
aspnet_wp.exe (PID: 2324) stopped unexpectedly.
It fails predictably on the dev web server in VS2005, less regularly on IIS
(although it does still fail).
I've tried to create a simplified program to reproduce the problem - so far
without success. However I did notice that the problem was worsened by some
code returning an array (15-20) of small Dictionary<> objects. I added a
conversion routine to turn them into arrays of structs, and some of the
problems went away. Is this something to do with memory-shortage' My PC has
800mb, with around 80mb free when running the code.
Whats going on? Is this a bug in .NET2, or is there something stupid in my
code? Advice would be welcome!!

Thanks,

post an update when I know more.

Microsoft report the problems stems back to a Dictionary<decimal,double>
instance.
Looks like the CLR can't cope with this for some reason. Be afraid....

System.InvalidCastException

I have UI Page.aspx which has this class:
PAGE.ASPX
private class Blah
public bVar as boolean
end class
On page load this class is added to the collection ColBlah and sent to the
function in business layer which has identical class defined.
BusLayer.vb
private class Blah
bVar as boolean
end class
class BusLayer
Public function Process(oCol as collection)
dim oObject, oBlah as Blah
for each oObject in oCol
oBlah=CType(oObject,Blah)
next oCol
end class
the line oBlah=CType(oObject,Blah) generates the following exception
System.InvalidCastException
Why? Anybody?A class can't exist in two places at the same time. Just because they have
the same name and share all the same members, doesn't make them the same.
As far as .NET is concerned, you might as well be trying to cast a textbox
to a database connection.
This class should be defined in your business layer ONLY...and your aspx
page should create an instance of THAT class.

System.InvalidCastException:

I have a page that gets a value from the querystring. I believe people click certain javascript functions on the page that sometimes appends a "#". I have never seen a page error out to this, but I am getting my logfile full of errors like the one below?

System.InvalidCastException: Cast from string "146586#" to type 'Integer' is not valid.

What would be a good way to stop this? Should I somehow trim the very last character if its equal to a "#" .

If so, how can I achieve this?

Thanks
mike123That is weird. The only time I have seen a # appended is when somebody uses the onclick in a A tag

for instance:Click me

In my opinion and to avoid these @.$R # signs is to use this:

Click Me

System.InvalidCastException: Specified cast is not valid.

ch JIt would help if you told us the line #. Is it at:
((DropDownList)e.Item.Cells[0].Controls[0]).SelectedValue="one";
First of all, it looks like you are doing that when ItemIndex == 0
wouldn't that be ur HeaderTemplate in which case cell[0].Controls[0]. really
might not be what you expect. Secondly, you might prefer
e.Item.FindControl("dll") or e.Item.Cells[0].FindContorl("dll") (not sure
which will work, favor the first one if it'll work) over using indexes. It
makes your code more flexible and less likely to break. Sometimes literals
(like spaces and newlines) are converted to controls, so while you might
think it's Controls[0], it might really be Controls[1] 'cuz there was a
newline before it.
It should be pretty easy to step through your code and debug though...

System.IO.Directoryinfo throwing exception

I have an aspx page that is set up to copy backed-up DB files from a shared
directory to a local folder. For some reason, it is being denied access to
the network share. I have the web app running under a domain account that I
know for a fact has access. it works fine when I log on to the network and
browse the directory manually. Even when I grant full control to everyone on
the share and the underlying folder itself, I still can't access it through
code. The funny thing is though, this same code works fine when executed
within a windows service which runs under the same domain account. Help!

End TryAnother MVP has written a great article about this
http://west-wind.com/weblog/posts/1572.aspx
The crux is (and its a pain to get working) that using Anonymous
authentication (so no impersonation) the local ASPNET account has to have
the same credentials (username and password) on both machines in order to
delegate security. With basic authentication and impersonation you need to
use a domain account which can delegate and you can check how to mark your
impersonated account able to use security delegation here:
http://msdn.microsoft.com/library/d...>
NetHT05.asp.
This is also required if you want to use NTLM authentication over kerberos
Personally, I would implement a the remote server as an http device and use
http requests, checking the referrer whihc makes life a lot simpler than
using mapped network drives.

System.IO.Directoryinfo throwing exception

I have an aspx page that is set up to copy backed-up DB files from a shared
directory to a local folder. For some reason, it is being denied access to
the network share. I have the web app running under a domain account that I
know for a fact has access. it works fine when I log on to the network and
browse the directory manually. Even when I grant full control to everyone on
the share and the underlying folder itself, I still can't access it through
code. The funny thing is though, this same code works fine when executed
within a windows service which runs under the same domain account. Help!

Code follows:

The crux is (and its a pain to get working) that using Anonymous
authentication (so no impersonation) the local ASPNET account has to have
the same credentials (username and password) on both machines in order to
delegate security. With basic authentication and impersonation you need to
use a domain account which can delegate and you can check how to mark your
impersonated account able to use security delegation here:
http://msdn.microsoft.com/library/d.../SecNetHT05.asp.
This is also required if you want to use NTLM authentication over kerberos

Personally, I would implement a the remote server as an http device and use
http requests, checking the referrer whihc makes life a lot simpler than
using mapped network drives.

The crux is (and its a pain to get working) that using Anonymous
authentication (so no impersonation) the local ASPNET account has to have
the same credentials (username and password) on both machines in order to
delegate security. With basic authentication and impersonation you need to
use a domain account which can delegate and you can check how to mark your
impersonated account able to use security delegation here:
http://msdn.microsoft.com/library/d.../SecNetHT05.asp.
This is also required if you want to use NTLM authentication over kerberos

Personally, I would implement a the remote server as an http device and use
http requests, checking the referrer whihc makes life a lot simpler than
using mapped network drives.
