Yes, OnDraw gets called in that case. Try to use your debugger to watch your data. Press F5 to start the debugger and F9 to put breakpoints. Try putting a brakpoint in the OnDraw function.

Ok, I hope I put this in the correct forum. Please bare with me as the question is rather long.
The development environment I am working in is Labwindows/CVI 6.0 (http://www.ni.com/lwcvi/) for the application and visual c++ 6.0 for the GINA.
For an application I was trying to lock the keyboard. Users could then unlock the keyboard by choosing a menu item after which a password box is displayed where a user can enter the password to unlock the keyboard.
I did this by creating a low level keyboard hook to catch all keys except ctrl-alt-del which cannot be intercepted this way. To make sure the password would not be blocked by the lock I would check if the password input field was the active control and if so, some keys would work (letters, numbers, backspace, enter)
To catch ctrl-alt-del I created a GINA stub based on the ginastub example in MSDN. I would then set a mutex in the application when it was locked. After pressing ctrl-alt-del the custom GINA would look for the mutex and block ctrl-alt-del if it found the mutex.
The problem was that when the keyboard was locked, after pressing ctrl-alt-del it wasn't possible anymore to give the password. The letters would just not appear on the screen. It took me some time to figure it out but the solution was to never block the ctrl button in the hook function.
Although I got the solution now I am very curious as to why it is necessary to never block the ctrl button.
I can post some sample code if required.

Hope this will help u.
You must modify the .hpj file to correct any file paths that are now invalid. You may also modify the custom build step to provide more informative error reporting.
To modify the .hpj file:
1. Open the .hpj file in Visual C++.
2. Examine its [FILES] and [MAP] sections for hard-coded paths. Modify them as necessary. Notice that the default installation path for Visual C++ 6.0 is as follows: \Program Files\Microsoft Visual Studio\VC98 whereas the default path for Visual C++ 5.0 is as follows: \Program Files\DevStudio\VC
To upgrade the custom build step rule:
1. Right-click the .hpj file in FileView; then click Settings on the Context menu, and click the Custom Build tab in the Project Settings dialog box.
2. Visual C++ 5.0 uses the following custom build step command to build help files:
call "$(ProjDir)\makehelp.bat"
Modify this text in the Commands list box to the following, assuming Makehelp.bat has not been changed from its original form:
start /wait hcw /C /E /M "hlp\$(InputName).hpj"
if errorlevel 1 goto :Error
if not exist "hlp\$(InputName).hlp" goto :Error
copy "hlp\$(InputName).hlp" $(OutDir)
goto :Done
:Error
echo hlp\$(InputName).hpj(1) : error:
type "hlp\$(InputName).log"
:Done
NOTE: The above steps are the default for a new project in Visual C++ 6.0.
3. Delete Makehelp.bat from the project; it is normally in the Help Files folder. If desired, you may also delete the Makehelp.bat file as well.

if the help file is compiled as HTML then use the Win32 API HtmlHelp .
else you can write like this.
CString strDefaultDir;
strDefaultDir=AfxGetApp()->m_pszHelpFilePath ;
strDefaultDir.Replace(_T("TestApp.CHM"), _T(""));
SetCurrentDirectory(strDefaultDir);
ShellExecute(NULL,"open", "TestAppHelp.txt", NULL, NULL, SW_MAXIMIZE );
where TestApp is the application name and TestAppHelp is the help file name.
Hope this helps.
Appu..

I have a problem like your.
I solved it with this corrections:
Add the macros
ON_COMMAND(ID_HELP_FINDER, CMDIFrameWnd::OnHelpFinder)<br />
ON_COMMAND(ID_DEFAULT_HELP, CMDIFrameWnd::OnHelpFinder)<br />
ON_COMMAND(ID_HELP, CMDIFrameWnd::OnHelp)<br />
ON_COMMAND(ID_CONTEXT_HELP, CMDIFrameWnd::OnContextHelp)
to the Mainframe map
And add to the constructor of the application
EnableHtmlHelp();
Then put the help file in the exe folder.
Note. my help is an html help.
|
|
|
|
|
should i add these code as it is or any changes should be made. what do u mean by "mainframe map"
|
|
|
|
|
Sorry for the late:
As I sad: I solved the problem with this lines, now pressing F1 the help will be displayed.
mainframe is described in MainFrm.cpp
and there you can find the message map:
BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWnd)
ON_WM_CREATE()
ON_COMMAND(ID_WINDOW_NEW, OnWindowNew)
... //Add here
The app constructor is (usually empty) in another file: MyAppName.cpp
But note: this works with html help, but I think that the macros are the same in both cases

I want hand cursor on static box. I have used the following code, but its not working please tell me if there is a way out.
CString windir;
GetWindowsDirectory(windir.GetBuffer(MAX_PATH), MAX_PATH);
windir.ReleaseBuffer();
windir += _T("\\winhlp32.exe");
HMODULE hModule = LoadLibrary(windir);
if (hModule)
{
g_hCursorLink =CopyCursor(::LoadCursor(hModule, MAKEINTRESOURCE(106)));
}
FreeLibrary(hModule);
if (g_hCursorLink)
{
m_MyStatic.SetCursor(g_hCursorLink);
}
|
|
|
|

The code is a little bit terrifying 
Because if you just want to load the hand cursor, you will get it by
LoadCursor( 0, MAKEINTRESOURCE(32649))
Another thing is SetCursor will not change the cursor permanently.
Try this
BOOL MainWindow::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
if( pWnd == &m_MyStatic )
{
SetCursor( LoadCursor( 0, MAKEINTRESOURCE(32649) ) );
return TRUE;
}
return CWnd::OnSetCursor(pWnd, nHitTest, message);
}
CWnd should be replaced by your class name.

It needs (WINVER >= 0x0500). So I just used its value!

So which one is easy! Using it's value (Of course with MAKEINTRESOURCE  ) or defining WINVER once and using IDC_HAND.;)
