The ATL function CWindow::GetWindowText() doesn't work with CStrings, since CString is MFC. You need to pass a BSTR or a CComBSTR (easier to use, it handles memory management for you).

I have a dll that includes a particular header file. In my main application code it too uses the same same header file. When I include the header file for my dll it tries to inclue the header file twice. How do I get the compiler to only include the file if it has not already been loaded?
Example:
DLL.h File -
#include "Myheader.h"
MainApp.h File -
#include "Myheader.h"
#include "DLL.h"
Thanks for the help,
-Eric

The standard way to prevent multiple inclusion of a header file is to add this in each .h file. This example depicts foo.h.
#ifndef foo_h
#define foo_h
...
#endif

Ok.. I found it.
Needed to use #if !defined and #endif in the header file.

|
|
|
|

In Myheader.h:
#ifndef MYHEADER_H_INCLUDED
#define MYHEADER_H_INCLUDED
#endif There is also the #pragma once command, however I prefer the #ifdef method so that I can test for the presence of the symbol to tell whether a header has been included.

Hi all,
I was wondering...
How can you give the desktop or taskbar the keyboard focus? 
I know there is an SetFocus function but that only works for a window that's your app own.

In the Platform SDK for SetFocus, it includes the following sentence:
By using the AttachThreadInput function, a thread can attach its input processing to another thread. This allows a thread to call SetFocus to set the keyboard focus to a window attached to another thread's message queue.
Which should help you get around the (deliberate) limitation. You could always detach straight after.

But how can I get the Thread handle of the Desktop or Taskbar wich need to attach to?

GetWindowThreadProcessId should give you the information you need.
Iain.

I tried to that, but I don't really understand how it is supposed to be done. Must I do this in a callback function or can I do it in the winman? Could you please demonstrate this process in code please?

I'm using SetTimer() and KillTimer() with the simple WM_TIMER event in my CWnd application.
Given the ID number for a timer which has been set, is there a way to find out how much time is remaining before the next call for that timer?
|
|
|
|
|
No, for two reasons. 1, the timeout you pass to SetTimer() is usually not the same as the actual timeout used by the OS. The actual timeout is always a multiple of a hardware timer (about 55 ms I think on Win 9x). 2, WM_TIMER is posted to your message queue, and it's impossible to predict how much time will elapse before that message is processed.

Hello.
You can use the CFormView Class .The FormView have a look like Dialog.You can place a RichEdit control on the top of form view and place a Edit control on the bottom of form view.
Good luck!
|
|
|
|
|
Hi,
thanks for ur idea TLiu, I'll try that, but I still wonder how to do to display a text on the RichEdit control.
thx very much.

You can reference to MSDN about CRichEidt.I remenber that there is a sample in MSDN about wordpad.Using CRichEdit in the sample.;)

I'm working on a MDI in which I use CScrollView for the document view. I want to use the mouse wheel strictly for a special zoom function but, if I click on the scroll bar, the mouse wheel activates both my zoom event and the natural scrolling of the window.
How do I prevent the mouse wheel from scrolling the view?
|
|
|
|
|
You just need to add a handler for WM_MOUSEWHEEL. Unless you handle it explicitly, it is translated
into WM_VSCROLLs. Just type WM_MOUSEWHEEL into MSDN help index, and there are plenty of pages which
can help you.
Good luck,
Iain.
|
|
|
|
|
Yes but I've already added a handler for WM_MOUSEWHEEL. My CScrollView now correctly zooms my view in an out with the mouse wheel but, if I click on the scroll bars, using the mouse wheel still scrolls the window as well as zooming it. It only seems to happen when a scroll bar was the last interface item clicked.
|
|
|
|
|
If you've got a
BOOL CMyView::OnMouseWheel(UINT fFlags, short zDelta, CPoint point)
{
...
}
function in your class, and a
ON_WM_MOUSEWHEEL()
in the message map, then the CScrollView::OnMouseWheel should never be called.
Unless you are calling it from your function?
I would also check the return value from the function. There are only two, so
try both. I reckon FALSE would be correct, but I can't check at the moment.
Iain.
|
|
|
|
|
Ah! That was the problem. I did prevent CScrollView::OnMouseWheel from being called but I was returning FALSE from the OnMouseWheel event. When I changed the return value to TRUE, it prevented wheel-based scrolling.
Thanks for the help!
