It's not just you. There are some questions that are so blatantly obvious they shouldn't even be asked.

It's not just you. The standard of question does seem to be in decline.

Are you binding it? If so, check the datasource for the number of rows.

Is there not a property such as Count or RowCount, or a collection of rows which you can then Count.

Does Vs2005 allows seperate reference for debug and release?

Hi all,

Can anyone help me figure out weather vs2005 c# allow to have two different references for debug mode and release mode in the same project.

Thanks in advance

If include the referred assembly's project into your solution and then put a reference to that project instead of directly referring the assembly, you will get configuration dependent references. I admit that this is kind of awkward, but it's the only way that I know of.

According to Microsoft, there is currently in VS2005 one xml proj file that holds the project properties, including a separate item group node for file and project references. The same file is used for both debug and release mode settings. This is definitely a limitation (for the time being). But improvements are under way[^].

blocking Peek() on StandardOutput stream

thomas1234510-Jan-07 0:35

Does anyone know why Peek() is blocking when called on the StandardOutput stream?
I've heard that it might block if nothing ever has been written to the stream before Peek() is called. The problem occurs both with VS2003 and VS2005 (.NET 1.1 & .NET 2.0).

System.Diagnostics.Process p = new Process();
p.StartInfo.FileName = @"c:\windows\system32\notepad.exe";

p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.Start();

int res = p.StandardOutput.Peek(); // this blocks
if (res>=0)
{
string s = p.StandardOutput.ReadToEnd();
}

Please help!

or simply

int c = 2 + 3;

If you're asking questions on this sort of level, the answer is to abandon asking questions, buy a book and work through it.

I was offering serious advice. If he doesn't know how to add two integers, who knows what he'll ask next ? It's quicker for him to work through a book, at that level.

At least somebody would be using it then. It's a great forum with not a lot being put on it.

    }

Usage example: Sum(3,4). Will return 7.

Sorry no. Wrote this in about 10-15 minutes. Tested it with two numbers and it worked. Good enough for me. I didn't want to spend more time coding this, as I think I already took this joke a bit far (though it would've been nice to write some code without using the increment operators Big Grin | :-D
