I would like to create a COM object with all my ADO methods. I then would like to have Visual Basic pass a recordset pointer to my COM DLL. Is this possible? If so how would I go about it?
Thanks

Hi,
I am developing an application with Visual C++ 6.0.
In the Visual C++ IDE, I can run my application in debug mode.
However, I can't run it in release mode.
How can I correct this behavior ?
Thanks,
Claude

Hi,.
I have a Visual C++ 6.0 application. I have saved numerous files with this
application with the Doc/View architecture of MFC.
I want to add variables to save and retreive. I know that we can have
version number in the context of serialization with IMPLEMENT_SERIAL(CMyDoc,
CDocument, version).
Does it creates a problem to change DECLARE_DYNCREATE to DECLARE_SERIAL in
the CMyDoc ?
Thanks,
Claude

No, it should work just fine. DECLARE_SERIAL() incorporates DECLARE_DYNCREATE() plus serialisation.

Hi,
I wish to have two different views of the document (in a MDI app) but with different menus for each view.
I basically want to use a class A and use it for different methods. Each method
would require a different view and different options - hence a new menu system.
I have two class extensions of the view and do AddDocTemplate for each new template.
However it only brings up the dialog to choose the view if the IDR menu resource is the
same.
When I use the same menu for each call to new CMultiDocTemplate it works as wanted
except that the menu is the same. I don't want to dynamically carve the menu at runtime
so there must be any easier way.
Does anyone know what I am doing wrong?
Regards,
flip

I've used a solution from an article on this site: http://www.codeproject.com/docview/replacingview.asp[^]. To change the menu as well, just call AfxGetMainWnd()->SetMenu(pMenu).
Hope this helps,
Ryan

Thanks Ryan.
That worked. I just put
HMENU hMenu = ::LoadMenu(NULL,MAKEINTRESOURCE(IDR_MYNEWMENU));
::SetMenu(AfxGetMainWnd()->GetSafeHwnd(),hMenu);
::DrawMenuBar(AfxGetMainWnd()->GetSafeHwnd());
in OnInitialUpdate() in the (second) doc.
I just mistakenly thought that specifiying a unique view and a unique menu resource in an MDI app with document templates should work the way I intended.

Unfortunately, it doesn't 
Well I've never got it to work, anyway

Hello
I'm writing an application which needs to be run in Systray. This systray icon has a popup menu attached with it. The problem after activating that menu if I click on any other application or any other part of desktop the menu is not deactivated. It's only deactivated if I choose one of the menu elements. I'm using MFC dialogs and my class is subclassing CDialog. I'm creating invisible window in this class. I'm not able to solve this problem.
If anyone knows how to solve this problem please help me with an example.
anxiously waiting for reply
Thanks in advance
Hari.

This is documented in the MSDN docs. The solution is to set your hidden window to be the foreground window before calling TrackPopupMenu() and send a dummy message to your window afterwards:
SetForegroundWindow();
menu.TrackPopupMenu(TPM_LEFTBUTTON | TPM_RIGHTBUTTON, point.x, point.y, this, NULL);
PostMessage(WM_NULL); Hope this helps,
Ryan

Thank you, I Used this to work out what was holding the file open, But what i was hoping for was to be able to report from my program the PID of the Naughty Process.

While creating my owner-drawn button class I encountered such a mmm... problem.
E.g. when you launch your app in Visual Studio you can press a button on the toolbar or Ctrl+F5. In the first case standard Windows buttons doesn't draw the focus rectangle untill you press the Tab button, but in second case they draw that damn rect.
How can I do the same.

I would like to be able to create a CFrameWnd derived class that doesn't need a toolbar. Right now I have a single doc/view architecture and if I remove IDR_MAINFRAME (default menu item), I get an error about not being able to create an empty document. How does one get rid of the toolbar?
Cheers,
Clint

One way would just be to hide it before the app becomes visible.

Your toolbar is a member variable inside your CFrameWnd-derived class. Just delete the variable and all references to it, and it won't be there.

Go to CMainFrame::OnCreate() and remove the line that creates the toolbar.

I' have a little problem with keyboard input. For control input (shift, crtl, arrow,...) Virtual keys are defined and is use them in th OnKeyPressed function (like you see in de code).
If i press the shift button, is see the right messageBox, if i press the up arrow nothing happens. But if i hold the up-arrow down, and press another key i get a messagebox saying "up key pressed", so the problem is not that the virtual key is wrong, but that no KeyPressed event is fired when the up arrow is pressed. Why? And even more important, what to do about it?
Here's the code
void CKeyboardDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if(::GetKeyState(VK_SHIFT) <0)
MessageBox("Shift pressed");
if(::GetKeyState(VK_UP)<0)
MessageBox("up arrow pressed");
...
}

There are various kbd messages you need to handle depending on what you want to process: WM_KEYDOWN/UP, WM_SYSKEYDOWN/UP, WM_CHAR, WM_SYSCHAR, WM_DEADCHAR, WM_SYSDEADCHAR.
This is all documented in the SDK Help!
UpArrow etc. are WM_SYSKEYxxx messages from memory.
