the system is reporting events and the debug window is picking up on them. it's pretty much harmless.

The reason the dll is being loaded in your process is because it probably installs some sort of global hook via SetWindowsHookEx. The dll will then be loaded into all running processes.

If you can, use WININET[^] instead. It makes things
much easier. MFC[^] has good wrapper classes for it
too.

Dialog Box and toolbar buttons

Member 314608823-Dec-02 2:36

I am having a problem with a dialog box and toolbar buttons. I cannot go into very much detail regarding all this code, since it is for my place of employment. But in our product, there is a main toolbar, which has several buttons. One of the is for user preferences. If the user has other windows open, clicks on this window, then goes back to another open window, he/she will have a problem when they click on the main toolbar. No matter which button is pressed, nothing happens because the dialog box is open and behind other windows. This isn't code that I have written but I am one of those responsible for maintaining. The code is written in C, not C++, MFC, or C#. I would like to be able to set the focus on the dialog box if anything on the toolbar is pressed. The problem is that I cannot find a way to do it, since I cannot seem to capture the message when the something on the toolbar is pressed.

A little detail, the toolbar is actually one bitmap, which contains several images. We have a special function that applied each individual image and makes it a button. So if the dialog box is open and behind other windows, it doesn't look like anything is getting pressed. Please HELP!!!!!

I'm trying to understand the exact problem, but it's not clear. Perhaps if you can explain it again by (1) saying what kind of app this is (ie., MDI, SDI, Dialog based), and (2) the sequence of steps taken to reproduce the problem.

Alvaro

This is a mixture of all three. It is a big application, with about 10 to 15 buttons on the main toolbar that opens windows, with the exception of the user preferences, which is a dialog box.

Alvaro Mendez wrote:

The sequence is simple. Just click on one or more buttons that brings up windows (not dialog boxes but actual windows) and then click on the button that brings up the user pref dialog box. Then, click on one of the other windows you brought up, not the button but the actual window. Now, the dialog box is hidden behind the other windows. When you try to click on a button on the main toolbar, nothing happens and the dialog box is hidden.

Maybe this an ownership problem? If the dialog that appears
when you lick on a button was owned by the window hosting that
toolbar, it should always appear above the window-- never
behind others. Make sure the call to create your dialog box
passes in the handle to your applications main window.

The Elusive CScrollWnd

I'm looking for a "CScrollWnd" version of CScrollView -- basically one that I can derive from without requiring the document/view architecture. Is there such a beast?

If not, is there a good tutorial somewhere for doing all of the scroll stuff (proper tracking sizes, etc?). I'm making a custom control and it's been a quite while since I've had to do this.

Thanks in advance!

You can create a CWnd with the WS_HSCROLL and WS_VSCROLL style.

learn all you can from MSDN's pages on scrollbars.

one instance of dialog box

dear all,
i have an mfc dlg based app which adds an icon in the taskbar, which on dbl clicking shows up a dialog box.

this dialog box is not the main window of my app.

the main window is a frame which is hidden (m_pMainWnd= CFrameObj) and this frame is also associated with the taskbar icon.

the problem is every time i dbl click on the icon, a new dialog box appears but i want only one dialog at a time

how do i go 'bout it?

I use a static variable:

static HWND s_hWnd = 0; //window handle of this dialog

// Create new dialog
int CMyDialog::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
	if(s_hWnd) { //window is allready opened?
		::SetForegroundWindow(s_hWnd);
		return -1;
	}
	
	if(CDialog::OnCreate(lpCreateStruct)==-1) 
		return -1;
	s_hWnd = m_hWnd	//store handle
	
	return 0;
}
void CMyDialog::OnDestroy() 
{
	if(s_hWnd==m_hWnd) s_hWnd = 0; //reset window handle of this dialog
	CDialog::OnDestroy();
}
