HWND hWnd;//declare is Global
<br />
hWnd=CreateWindow("EDIT","",WS_CHILD|WS_VISIBLE,0,0,150,23,m_hWnd,NULL,AfxGetInstanceHandle(),NULL);<br />
::SetWindowText(hWnd,"Test");<br />and where you use this code (which function)

By any chance is this happening on a seperate thread?
Are you sure that the IDC_Message is a valid control ID for the control you are looking for? Are you sure that it has already been created and has a message pump pumping messages for the dialog?

If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

yes i'm sure that Control ID is Correct but for "Are you sure that it has already been created and has a message pump pumping messages for the dialog?"
But How to Check the this i didn't do anything for that.

Use ::GetDlgItem( CTRLID ) to get an HWND for the control. Then use ::IsWindow( HWND ) to see if it is valid. Do not assume that a non-NULL HWND is always a valid one - it could be garbage, or it could refer to a destroyed control (especially if it is stored in a variable or the control is destroyed in-between the two calls).
A brute-force way to see if the control has a pump is to use ::SendMessageTimeout(...) to send a WM_NULL value to the control and see if the message is processed or if an error/timeout happens.

when i use this code then if condition does not satisfy and it passes the if condition.
what to do?

If the call to ::IsWindow(...) fails, then you are trying to refer to an incorrect window/control. You could be in the wrong dialog (or parent window), or have the wrong control ID, or just be calling the code at a point before the controls are created or after they are destroyed.

GetString(HINSTANCE hinst)
Compiler gives error as HINSTANCE is undecleared identifier.
I am devoloping this project without MFC control. Where i am doin wrong?
Do i need to include any header files??

thx john!
I bulild the library. But the problem is that its giving me error 1814 i.e The specified resource can not be found........
I had been told that when we build .lib static library...we can not have resource file in that. IF its there we need to add .rc file along with the .lib file whenever needed.
Is it true??
