Which identifier is not found ? Your post is lacking of relevant information.
Identifier not found probably means that you forgot to include a header file.

You can call any function you have access to from your thread.
Write a cleanup function and call it?

Are you thinking along the lines of InitInstance/ExitInstance virtual initialization/cleanup
methods?

Take a look at CWnd::RepositionBars. MSDN has a nice sample on this too.

For the sample you will have to search MSDN with the keyword as RepositionBars.

How I can add Text on the image?

Hi all.

I have a bmp image and i have set it as a back ground of a dialog box. But the controls on dialog box are not getting matched with the colors from image. I mean the background of various controls like check box, radio button, static controls, etc is typical system color, i.e. off brown.

I can set the background color of the controls by overriding OnCtlColor() of CDialog class. But to set their backgound, I need the color from image, and as image is having number of colors I can't go with one perticular color?

My question is how I can make back ground colors of the controls exactly same as that of image color on which I have dropped them?

Thanks

In fact what you want is transparent controls, am I right ?
See if these articles help:

Transparent static text[^]
Transparent controls on PocketPC[^]

(even if the last is for pocketPC, you'll probably find usefull information looking at the code).

how to detect a modal dialog box coming up and to response to the dialog box

I have been racking my brains to figure out how to detect a modal dialog box coming up and to response to the dialog box by lines of code which simulating "press ENTER key " or "clicking a button".

In my project, I import a dynamically linked library to use some functions. One function bring up some modal dialog boxes, suspending the main thread. I want to responsing to the dialog box as soon as it pops up by simulating the act of "Pressing the OK button on the dialog" with code. On the dialog box, there is only a OK button(having focus). Currently, I have to press the OK button manually whenever a dialog box comes up. I think the solution involves two aspects: (1) detect the occurrence of a dialog box; (2) simulate "Pressing the OK button on the dialog" with code.

Can anyone help please. Without a solution, I have to reponse manually to handreds of thousands of dialog boxes to keep my program running.

By the way, there is no way I contact the authors of the dynamically linked library to solve this problem.

One solution would be,
Get handle to that dialog, (using FindWindow(), you could use timer for this).
And then use SendMessage(WM_CLOSE,..).

i.e.

void MyTimerProc(LPVOID)
{
    HWND hDlg = FindWinow(NULL,_T("Dialog Title"));
    SendMessage(hDlg,WM_CLOSE,0,0)
}

Prasad, Thank you.

You suggestion is perfect. It works fine now.

However, in my code context, i have to put scope operator :: before 'FindWinow and 'SendMessage'.

I do not know why. When searching MSDN, I found two FindWinow(). One is a member function of class CWnd; the other does not beloge to any class. I guess by using "::" , i.e., ::FindWinow, we actually refer to the latter. I am not sure about this.

Hi,

you can use CEDIT Member function..

CEdit* pmyEdit;

// Delete all of the text.
pmyEdit->SetSel(0, -1);
pmyEdit->Clear();

Kind Regards,
Priya.

You get message box in all cases.

If you want to perform validations, use PreTranslateMessage of you CEdit derived class instead.

BOOL CMyEdit::PreTranslateMessage(MSG* pMsg) 
{
	if ( pMsg->message == WM_CHAR)
	{
	     UINT nChar = (UINT) pMsg->wParam;
             if ( nChar <=57 && nChar >=48 )
	     {
                 return TRUE;//char will not be entered
             }
	}
	return CEdit::PreTranslateMessage(pMsg);
}
