Hello everyone,
Ok, I've got a HWnd (the HWND was returned from an ActiveX control). I pass the HWND to a .NET control. I try to pass the HWND using Control.FromHandle() function and I get a null in response.
Why?
I want to make a .NET control become a child of the ActiveX control (this is so I can cover it, if you really want a full explanation, see below), so if there is another way of doing this, please let me know.
Thanks,
Adrian

Full Explanation:
Using a language called LabVIEW 7.0. Doesn't allow for .NET controls, but does allow for .NET objects. Want to put control on a front panel of a LabVIEW window. LabVIEW doesn't expose the window handles, so created an AX control which is to return the handle of the AX control so that I can paste the .NET control on top of it. What a work around eh?

How?? Using what?? Your statement makes no sense without specific information.

Control.FromHandle will only work with controls based on the .NET Framework's Control class. It will NOT work with Win32 handles. You cannot write a control in native Win32 and force the Control class on top of it.
Your best solution would be to contact LABView support and see if they have a .NET compatible library that does what you need, or if they even have a workaround for this.

As I am using a Stored Procedure named 'HP_FindToken'
I want to get the value of @Token ,@FileNO,@SpOPNO
Is it possible to give any message box or any popup for finding what values are coming at the time of running without using output parameter.

There isn't a MessageBox command in SQL, but you can use the PRINT command in SQL Server to write some values that you're interested in

Hello,
I'm having a very big problem with the serialport class and I need some help to solve this.
we're using multiple serialports in a generic list since we need to connect to multiple devices.
This is what our basic code looks like...
List<serialport> ports = new List<serialport>();
private void button1_Click(object sender, EventArgs e)
{
ports.Add(new SerialPort("COM6"));
ports.Add(new SerialPort ("COM7"));
ports.Add(new SerialPort("COM8"));
foreach (SerialPort port in ports)
{
port.Open();
}
}
Now,after the button is clicked,...if one of the devices(mobile phone in our case) is switched off or if its cable is disconnected from the USB port,there is an immediate massive memory leakage.
Please help us with a solution.
I have noticed a similar thread here...
http://www.experts-exchange.com/Prog..._23315204.html
and a couple of bug reports in Microsoft Connect.
But,right now I need some IMMEDIATE URGENT solution....Would really appreciate if someone helps.
Thanks so much

I have never seen a memory leak while using serial ports.
What are the exact symptoms?
Can we see code for your asynchronous handlers (DataReceived, ErrorReceived, PinChanged)?
Are you logging (or at least counting) them? Noticed anything peculiar?

what is the best and fast way to import and export data from a flat file to a database in dot net with sql server 2005. Should we have to write our own code or is there any service to do this. [other than using DTS (SQL 2000 only) / SSIS ]. Kindly copy some reference URL.

Depending on the format of the flat file you could set up a Bulk load query in SQL.

Hi (:
Im currently developing an application in C# that requires chat/support discussion features.
I have all of the back-end networking sorted out, But im stuck when it comes to the UI. . .
I cant find a nice and efficient method for displaying the chat session/logs to the users.
Ive tried using just a textbox.. but it looks primitive, Ive tried using Chat Controls i have found online, but they wouldn't work. . . and i have tried using HTML rendering controls from here on CP, but when the message stack builds up the rendering slows the whole UI.
Could someone, maybe who has tackled a similar situation, offer some advice as to how i could go about both professionally and efficiently displaying chat sessions in my UI?
Thanks for your time in reading,
Andy.

I want to be able to put an entry in my app.config so that, regardless of the user running the app, it will still point to their "My Documents" folder. The user's PCs are very locked down, and all they have access to is that folder, but obviously that folder is in a different location on every PC. Is there a way to use an environment variable or something, so that it always points at "My Documents" for the current user, wherever that is?
