I am trying to log a user into a site using HttpWebRequest or WebClient Class
Now the site will probably issue me some cookies that tell the browser i'm already logged in. I need to pass those cookies on subsequent requests so I can fetch the data on that page.
Thanks in advance

Exactly. As for the cookies, just copy all the cookies you receive in the Response to the subsequent Request(s). This is simple.

Hi,
I've a list box with 4 columns out of which one column has width as 0 and want to restrict the users to re size it and see the content. How can get this ?
Thanks

If you don't want the content vsible, why put it in the visible part of the control at all? I would either:
0. Store the required non visible data in the Tag property of the ListViewItem
1. Subclass ListviewItem to have a new property of the correct type to store the data to avoid unboxing/boxing associated with 0.

I thought, oh here we go that's s stupid question. Then I read the details and remembered that I have the same problem, not one I worry about but it is there.
I use a DGV if I need to hide a column, it support visible. I also have a utility that loads any table/dataview into a listview that assumes the first field is the ID and it gets loaded into the tag property.
If the list is short I sometimes load the datarow into the tag property and only create cols for the fields I want to display.

Have some issues and questions about creating a .dll from code in the form of a string array and a file. I seem to be close, but errors are raised when the code tries to creat the .dll.
Main question is, does the 'OutputAssembly' refer to the file name to create? Whenever I run the code below it says it could not find the file that 'cp.OutputAssembly' is set to. Also if this line is commented out, it says it could not find a randomly named file in a temporary directory.
The other question I have is if there is any difference between creating the .dll from an existing file or a string array. I plan on having the system create a common .dll for both the main program and for other .dll's the main program creates. These non-common .dll's can then be used directly in other programs.
This code is to create the common .dll .
public CompilerResults CompileImageAquisition(string OutputFile)
{
CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
CompilerParameters cp = new CompilerParameters();
CodeTypeReferenceCollection cref = new CodeTypeReferenceCollection();
cp.OutputAssembly = OutputFile;
cp.GenerateInMemory = false;
cp.TreatWarningsAsErrors = false;
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\PresentationCore.dll");
cp.ReferencedAssemblies.Add("System.Drawing.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.Windows.Forms.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.XML.dll");
CompilerResults cr = provider.CompileAssemblyFromFile(cp, ImageCoderSourceLocation);
if (cr.Errors.Count > 0)
{
Console.WriteLine("Errors building {0} into {1}", ImageCoderSourceLocation, cr.PathToAssembly);
foreach (CompilerError ce in cr.Errors)
{
Console.WriteLine(" {0}", ce.ToString());
Console.WriteLine();
}
}
else
{
Console.WriteLine("Source {0} built into {1} successfully.", ImageCoderSourceLocation, cr.PathToAssembly);
}
return cr;
}

'OutputFile' has the directory of the file you wish to create such as "C:\\Folder\\File.dll". You can also set 'cp.GenerateExecutable = True' to have it create a .exe file.
'cref' is the directory to a C# file, such as "C:\\Folder\\Code.cs", but can also be a .txt.
You should be able to modify the code so the 'ReferencedAssemblies.Add' lines look more like "cp.ReferencedAssemblies.Add("System.dll");", but I was having some issues with it not being able to compile without the full path. This could just be a bug in VS2010 beta.
public CompilerResults CompileImageAquisition(string OutputFile)
{
CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
CompilerParameters cp = new CompilerParameters();
CodeTypeReferenceCollection cref = new CodeTypeReferenceCollection();
cp.OutputAssembly = OutputFile;
cp.GenerateInMemory = false;
cp.TreatWarningsAsErrors = false;
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\PresentationCore.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.Drawing.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.Windows.Forms.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.XML.dll");
CompilerResults cr = provider.CompileAssemblyFromFile(cp, ImageCoderSourceLocation);
if (cr.Errors.Count > 0)
{
Console.WriteLine("Errors building {0} into {1}", ImageCoderSourceLocation, cr.PathToAssembly);
foreach (CompilerError ce in cr.Errors)
{
Console.WriteLine(" {0}", ce.ToString());
Console.WriteLine();
}
}
else
{
Console.WriteLine("Source {0} built into {1} successfully.", ImageCoderSourceLocation, cr.PathToAssembly);
}
return cr;

Hi Guys
I have quite an urgent problem which is really getting on my nerves...
I have a stream reader which goes through a file line by line, and extracts information. The problem I have though, is that for some reason, the very first character is getting left out...
string chkLine = ChkReader.ReadLine()
Does anybody know why this could be happening? 
Thanks
oooo, the Jedi's will feel this one....

Is the first character anything special? What encoding are you using? Is the first character even there - check with a hex editor?
I use StreamReader quite a bit, and it's never given me a problem, and never left out any characters.

The first character is a number. nothing special. It misses all of them though. It's not like it's just dropping a leading zero... It is very baffeling. Just does not make any sense.

You mean it misses the first character of every line?
File:
0Hello
1There
2Goodbye
gives you three lines "hello", "There" and "Goodbye"?
What is so different about your code from the standard and very boring:
using (StreamReader sr = new StreamReader(@"C:\XXTemp\Lines.txt"))
{
string s;
while ((s = sr.ReadLine()) != null)
{
MessageBox.Show(s);
}
}

My code is:
while (chkReader.Read())
{
string chkLine = chkReader.ReadLine();
}
I just created a new text file of my very own and pointed my app at it and got the following:
Actual line in file: "Hello There"
Line picked up in chkReader.ReadLine(): "ello There"
oooo, the Jedi's will feel this one....

There's your problem: the while(chkReader.Read()) reads and discards the first character of each line...

 Your completely right... I can't believe I didn't spot that... More coffee is required me thinks!!!
Thank you

Try setting a break point in the below code snippet:
<br />
foreach (char c in ChKReader.ReadLine())<br />
{}<br />
See if it is picking it up using that.

Just tried your suggestion. It still misses it out...

|
|

|

Is the text file ANSI encoded?

Thats the assumption I'm making. Although I'm not sure how to check.
The text file appears to be a straight forward text file for use with the likes of notepad.

Well its hard to say, I would try creating a whole new text file, and typing in a few of the problem lines. That way you will know if the problem is the text file or your code.
The code you posted should work fine...

Hi,
you could create your special stream reader that does exactly that, or there could be something very special about your file (not sure what). To make sure, use a hex editor/dumper to look at the first few lines of data.

I edited the the question. becuase yes it works but the problem that am facing with it is that i am using the following Master Page --> Tab --> Grid -- > Text Box
An doing the following
response.write("document.getElementById('"+txt.Text+"').focus();");
it tells me that object is null and gives a js Error
I am using this method on page load so directly the focus will be on that textbox. The JS code that i wrote works fine if i paste it in the URL tab so there is no problem with syntax.
