TreeView.Nodes.Find function doesnot exist

In that case you may have to iterate through all the nodes and check it's value/ID or whatever you need - when you find a match, set the selectednode property and break out of your loop.

If you go to the top of this page you will see a textbox labeled SEARCH. Try that, there are loads of articles and code samples. If that doesn't help, try Google, again there are lots of very good examples.

can not obtain local variable value in Visual Studio 2008

Hello everyone,

When remote debugging a release version binary on a remote machine using Visual Studio 2008, there is error message from local host machine in Visual Studio when I try to see some local variable values.

The error message is (1st message is displayed when my mouse stops at the variable in Locals, the 2nd message is what is displayed when I pressed refresh button for the specific local variable),

--------------------
The value for this item is stale dues to a problem that occured while evaluating it. Hover your cursor over the refresh button for details.

newNumbers Cannot obtain value of local or argument 'newNumbers' as it is not available at this instruction pointer, possibly because it has been optimized away. int
--------------------

Such issue only happens with release version, debug version is fine. Any ideas how to solve this? I need to debug release version.

thanks in advance,
George

You cant.

Why dont you just log the value in a logfile in stead?

1.

You mean such situation is normal when debugging release version? And no way to solve?

I want to debug without changing the existing code. Smile | :)

Yes, it is called optimization, for starters it strip's all symbol names.

Actually, if all symbols can not be displayed, I will not be so surprised. My confusion is why only a part of local variable can not be displayed?

It depends on where you are displaying the data. If it is on an ASP.NET page then newline char will be <br>. Try Environment.NewLine

WinForms app, it will be displayed on a DataGridView and Crystal Report

Environment.NewLine has the same affect as "\r\n"...

i just noticed that its displaying correctly on the crystal report, but im seeing the square-like character in the DataGridView which is where the data is seen before the report is generated.

is there may be some property on the DataGridView to make it interpret the new line as a new line instead of the square-like character?

thanx

Looks like it don't support displaying multi line text. I am not sure about making gridview to display multi line text.

int myCounter = Int32.Parse(ConfigurationManager.AppSettings["NumberOfLoops"]);

while (myCounter < 5)
{
    doStuff();
}

remember to add using System.Configuration;

hope it helps

Remoting vs Sockets

nr10002202027-Jul-08 20:22

7-Jul-08 20:22

Hi,
I'm building an application for versioning purpose.
Though this versioning system is different from our regular software versioning applications like WinCvs, VSS etc (as my versioning system has more of the domain essence to it), the basic architecture would still remain same.
There is our client application containing some versionable elements, from which we trigger new versions, which would be stored in a repository at a server.
Here I'm stuck with the communication channel. I've figured out 2 ways of doing it
1. Using sockets
2. Remoting

Primarily there is only transfer of files involved between the client and the server.
I'd like to know which is the better way to go about it.
Also is there any other approach apart from remoting and sockets to form a client - server app with this kind of requirements?

Thanks in advance
