Here is an example as requested.

// Load the resource dll
HMODULE hModule = LoadLibrary("C:\\another_resource.dll");
 
if(hModule != NULL)
{
   // Loading your dialog
   HWND hDialog = CreateDialog(hModule, MAKEINTRESOURCE(ID_DIALOG), /* Handle to parent window */, /* Pointer to dialog procedure function */);
 
   // Loading your bitmap
   HBITMAP hBitmap = LoadBitmap(hModule, MAKEINTRESOURCE(IDB_BITMAP);
 
   FreeLibrary(hModule);
}

Use the LoadLibrary method to load your dll and call LoadResource to load the resources in it.

I think it's a known issue. The way to workaround this is by using SYSTEMTIME instead of CTime:

<br />
SYSTEMTIME ct1;<br />
<br />
if( m_month.GetCurSel(&ct1) )<br />
{<br />
strDate.Format(_T("%02d-%02d-%2d"),ct1.wDay, ct1.wMonth, ct1.wYear );<br />
MessageBox(strDate);<br />
}<br />

I hope that solves your problem,

How to capture KeyDown event in Dialogue based MFC Application ?

Hi
I have developed a simple dialogue based application. This application contains only one static control in which I show some text continuously. Now I want to put a code so that when user presses some key combination like Ctrl + M, Ctrl+Alt+M or any key, it should be closed.

But my OnKeyDown() function doesn't work as I have Static Control on my dialogue and it takes the focus so all my key down event goes to static control.

Any idea what to do ?

Thankx in advance

You can attach an accelerator resource to your dialog. In the accelerator table, you can map the key combination to some command and then add an entry to the message map to specify a command handler.

Take a look at this posts[^] for details on how to attach the accelerator.

Hope that helps,

You'll have to handle the WM_KEYDOWN message in PreTranslateMessage member function.

<br />
BOOL CYourDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
	// TODO: Add your specialized code here and/or call the base class<br />
	if(pMsg->message == WM_KEYDOWN)<br />
        {<br />
          ... // put your stuff here <br />
        }<br />
	return CDialog::PreTranslateMessage(pMsg);<br />
}<br />

I hope it helps,

Kill Win32 Application

Hello All,

I have implemented a simple "hello world" WIN 32 Application which displays a tray icon when application is running and removes tray icon when application is closed.

My problem is when i kill the applcation process from task manager, the tray icon still remains in system tray. When I move the mouse cursor over the tray icon then the tray icon is removed.

Will it be possible to remove the tray icon when application is killed from task manager.

Any help is truly appreciated?

Thanks and Regards,
Madhu

you need to call something like this before exiting your app:

Shell_NotifyIcon(NIM_DELETE, &nidIconData);

One important thing: killing an application is a really bad thing to do Smile | :)

. When you kill an application, the clean-up code is not executed and that's why your icon still remains. The best solution to this problem: quit your application normally Smile | :)

. Your application isn't supposed to be finished with the task manager killing it.

If you kill it by your task manager you can't predict what will happen and ensure that the icon is removed ... Unsure | :~

Thanks for the reply.

My application is launched from installation. The applcation runs similiar to daemon or service. So, i need to terminate the process during uninstallation. I am using TerminateProcess() to kill the applcation.

Is there any alternative solution?

Thanks & Regards,
Madhu

You have 2 options after TerminateProcess() has killed it:

- Try Shell_NotifyIcon[^]with NIM_DELETE.
- Or force a repaint if you have the handle of the system tray:

<br />
CWnd *tray=FindWindow("Shell_TrayWnd", NULL);<br />
tray->SendMessage(WM_PAINT,0,0);<br />

Why are you using TerminateProcess to Kill the process(Even MSDN caution you tp use that in extreme case), why don't you WM_QUIT/WM_CLOSE or similiar function to close the application
