System.Drawing.Text font question

Hello,

I've looked for answer to this everywhere but with no luck..

I need to dynamically create graphic text from database values. I've got this working fine if I use arial as the font but I want to use another font.

Now - presumably I can use any font installed on the server? But it doesn't seem to work. I want to use a font called blurLight but it just outputs in arial (I think - it's a standard font anyway)

Is there anything else I need to do to make other fonts available to asp.net other than just installing them on the server???

Thank you.Post some code so we can have a looksie
Alright - I will

<%@. Page Language="VB" Debug="True" %>
<%@. Import Namespace="System.Drawing" %>
<%@. Import Namespace="System.Drawing.Imaging" %>
<%@. Import Namespace="System.Drawing.Text" %>
<%
' Declare Vars
Dim objBMP As System.Drawing.Bitmap
Dim objGraphics As System.Drawing.Graphics
Dim objFont As System.Drawing.Font
objBMP = New Bitmap(100, 30)
objGraphics = System.Drawing.Graphics.FromImage(objBMP)
objGraphics.Clear(Color.Green)
objGraphics.TextRenderingHint = TextRenderingHint.AntiAlias
objFont = New Font("Arial", 16, FontStyle.Bold)
objGraphics.DrawString("Hello World", objFont, Brushes.White, 3, 3)
Response.ContentType = "image/GIF"
objBMP.Save(Response.OutputStream, ImageFormat.Gif)
objFont.Dispose()
objGraphics.Dispose()
objBMP.Dispose()
%

That code works fine but when I replace Arial with the font I want to use - it doesn't work..

Any ideas??

System.FormatException: Input string was not in a correct format

Hello all,

I'm looking for a long time to find out what's wrong, but I can't find the mistake...
The connection to the database works correctly (Select,..), but when I set up the Insert-Command by clicking a button I get the following exception. Does anybody can help me and tell me what's wrong?!

Thank you for helping!

The error is associated with a call to System.Number.ParseInt32(). That tells me that one of the parameters is expected to contain an integer or a string representation of an integer but does not. Identify integer parameters. Then in the debugger, determine if any of them are:
1. Not assigned. If a string is provided, is it an empty string?
2. Contains other characters than digits?
These two cases will generate that exception. (The .net docs for Convert.ToInt32 say FormatException will occur when:value does not consist of an optional sign followed by a sequence of digits (zero through nine).)

System.InvalidCastException: Specified cast is not valid.

i'm retrieving data with Repeater from Sql Database. i have color colums in the table.. such as color1, color2, color3, color4 and columns type Nvarchar.

i implemented below the function to get team colors instead of characters in the table cells

---- function -----

string Team_Colours(string color)
{
switch (color)
{
case "WHITE" :
color = "#FFFFFF";
break;

case "BLACK" :
color = "#000000";
break;

case "RED" :
color = "#FF0000";
break;
case "" : // i think problem is here

color = "";
break;
}

return color;
}

-----------

if all color colums are not null, everything okay.. but, i'm getting below the error if any color colums is null..

------error-----

Exception Details: System.InvalidCastException: Specified cast is not valid.

Line 159: <td bgcolor="<%# Team_Colors((string) DataBinder.Eval(Container.DataItem, "color4")) %>"
------------
how can i solve this problem ?

thanks..If it's Null at times, try Switch(color.ToString())
Or add the .ToString to where the color is actually being read from the database.

Hope this helps, but may need to see more code...

Zath
i tried that Switch(color.ToString()) but same eror :(
it's ok, thanks Zath..

<%# Team_Colors(DataBinder.Eval(Container.DataItem, "color1").ToString()) %>
<%# Team_Colors(DataBinder.Eval(Container.DataItem, "color2").ToString()) %>
<%# Team_Colors(DataBinder.Eval(Container.DataItem, "color3").ToString()) %>
<%# Team_Colors(DataBinder.Eval(Container.DataItem, "color4").ToString()) %>
I just tried your function and it works ok for me.
Are there any other colors in the database not accounted for?

Have you tried setting a break point in your code to help debug?

Maybe a little more code might help.

System.InvalidOperationException: Connection must be valid and open

Hi.
I am using this function tu execute updates to a MySql database from a sql
string, but I am getting a System.InvalidOperationException: Connection
must be valid and open.
Database queries work fine, but I cant update the source. Am I missing
something?
Thanks, Alejandro.

}Hello Alejandro Penate-Diaz,
Exactly what the error message says... You need to have a valid *and* open
connection.
Try adding conn.Open() before the command.ExecuteNonQuery() method.

Heyy, thanks!! Problem was that I was like copy-paste and didn't realize

System.Net.Mail issue - html AlternateView losing period in href

I have setup some code that grabs HTML from our database and attaches it as an AlternateView
--
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(htmlSB.ToString(),Encoding.GetEncoding(0),MediaTypeNames.Text.Html);
--
I am dumping it to a text file locally. In the instance where there is a wrap in the body which contains an a href, and there is a period just AFTER the wrap, it drops the period
ex of the physical email file:
blah blah blah blah <a href="http://links.10026.com/?link=http://forums.asp=
.net>Asp Forums</a>blah blah blah blah bla=
(note the period on the new line)
shows up as -
blah blah blah blah <a href="http://links.10026.com/?link=http://forums.aspnet>Asp Forums</a>blah blah blah blah bla
(note the missing period between asp and net)
Any ideas?
thanks
m

Since I have not gotten a response at all, should I assume that this is an unfixable bug and abandon system.net.mail?

thanks

System.Net.Webclient screen scraping: how to gracefully handle 403 (and other) errors?

I've written a very small ASP.NET page to scrape thousands of pages of
content based on database IDs. It loops through a dataset to get the IDs. It
worked well in testing but now I am getting an annoying 403 error that
causes the script to abort halfway through my download.

I am wondering if there is a way in ASP.NET to have my code ignore 403
errors and other network errors, catch the error, and iterate to the next ID
in the dataset rather than aborting the whole job.

My code appears below. Thank you in advance.

-KF

string strConnection;

strConnection = ConfigurationSettings.AppSettings["connwhatever"];

SqlConnection conn = new SqlConnection(strConnection);

string query = // [my query];

SqlDataAdapter a = new SqlDataAdapter(query, conn);

DataSet s = new DataSet();

a.Fill(s);

int counter = 0;

foreach (DataRow dr in s.Tables[0].Rows)

{

counter++;

System.Net.WebClient wc = new WebClient();

string strData =
wc.DownloadString("http://whatever.org/article.asp?articleid=" +
dr[0].ToString());

FileStream fstream = new FileStream(@dotnet.itags.org."c:\whateverpath\" + dr[0].ToString() +
".htm", FileMode.Create, FileAccess.Write);

StreamWriter stream = new StreamWriter(fstream);

stream.Write(strData);

stream.Close();

fstream.Close();please read chapter on try/catch

Understand try/catch generally. What event(s) should I be trying to catch?

Hello KF,

Based on your description, you're using the webclient class to request many
web pages programmatically in ASP.NET page code. However, since some page
may raise some exception, your client loop code in ASP.NET page break,
correct?

As for the 403 error, it is normally caused by the security authorization
checking at server-side fails. I'm not sure whether there is any other
particular scenario here, however, if what you want is simply captuer and
ignore such error and continue the loop, you can just add a try catch block
around your webclient class's downloadXXX method call and if any exception
captured you can simply ignore it and skip the current loop. e.g.

=======================
foreach (DataRow dr in s.Tables[0].Rows)

{

counter++;

System.Net.WebClient wc = new WebClient();

try
{

string strData =
wc.DownloadString("http://whatever.org/article.asp?articleid=" +
dr[0].ToString());

}catch(Exception ex)
{
//ignore and continue the loop
}

...........................

}
=========================

Does this work for your scenario?

You can specify error documents for specific error-codes.

In your web.config, add the following entries in <system.websection:

<customErrors>
<error statusCode="403" redirect="403.aspx"/>
</customErrors>

Note that generally, 403 would be given by the web server and not be the
ASP.Net engine. At times, when the authentication fails, 403 may be returned
by an IHttpModule - like the authentication modules (NTML, Kerberos, Digest
etc).
