What are these (Test2->Caption) where you change values of these
|
|
|
|
|
this looks like Managed C++.
have you thought asking in the C++/CLI forum[^] ?
|

Test2 is the name of my button and caption is the property of whats written on the button. It very possible that caption doesnt exist and i have to use text, but both doesnt work.
And as far as I know this isn't managed c++, unless I never done unmanaged c++ in my entire life.

Is this Button is your own activeX control ..

I'm having problems with class redefenition errors (4 of them, plus 93 other errors about not being able to find class defenitions). Include guards are in place in every file but I'm still getting errors becuase the classes are dependant on one another and I can't figure out a way for all the dependancies to be satisfied and still not get any class redefenitions.
The relevant files:
game_main.cpp
requires stdafx.h and game_operations.h (class CGameWin)
tree_operations.h (class TreeOperations)
requires stdafx.h
GameDialog.h (class GameOptionsDialog)
requires stdafx.h, and game_interface.h (class CGameWin)
game_operations.h (class GameOperations)
requires stdafx.h, game_interface.h (class CGameWin), and tree_operations.h (class TreeOperations)
game_interface.h (class CGameWin)
requires stdafx.h, GameDialog.h (class GameOptionsDialog), and game_operations.h (class GameOperations)
As you can see, I need class CGameWin in both GameDialog.h and game_operations.h, which is a problem since game_interface.h needs GameDialog.h. It makes a loop. I can post the header files if you need me to, but it will take up a lot of space. Please help me out with this.

Header files should never need stdafx.h. Stdafx.h must be the first file included in all your cpp files.
Can you do a simple forward declaration in one of your header files and then include the actual header file in your cpp file?

dear coder
how do i programatically prevent that a key does not repeat itself, in case that user press and hold that key (e.g a funktion key)?
thanks
cheers

hi WebSitesNG,
thanks for your reply.
i need it, because if the user accidentially press a particular key too long, so that it repeats itself, then this will result an error.
cheers

Check the previous key state bit.
void CMyWnd::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if (nFlags & (1 << 14))
{
return;
}
CWnd::OnKeyDown(nChar, nRepCnt, nFlags);
}
You may be right

I am writing a MDI appkication but there are times when the user tries to open a new window and I want to prevent this (e.g. when there is a resource conflict).
I tried putting PostMessage(WM_CLOSE, 0, 0) in the OnCreate function but it doesn't work.
Any ideas?

Returning -1 from the OnCreate method should abort the creation process and destroy the window.

It works but puts up a dialogue box with an error.
Commenting out the CView::OnCreate call causes an exception.

I'm going to try overriding CWinApp::OnFileNew, that should do it.
Thanks for trying.

Returning FALSE from CDocument::OnNewDocument() will also do it.

Also, returning FALSE from a PreCreateWindow() override will prevent the creation before the
associated HWND is created.

Unfortunately the causes an error dilaogue to appear.

I didn't know that. I'm going to have to look into that - if it's MDI-specific maybe(?)
Thanks!

It looks MDI specific but I suppose you could use OnFileOpen for SDI.

How to catch WM_CHAR ,WM_KEYDOWN in Dialog Base.
|
|
|
|
|
In MFC, by using The On*() handlers, or using PreTranslateMessage(...) from within the CDialog class. In straight C/C++, by adding the message identifiers to your message pump.
Many examples on this site catch those messages - if you do an article search for those messages, I am sure you will find matches.
Peace!

I've looked around but I think I'm looking for the wrong things because I instinctively feel there must be a very, very simple way for me to make a DateTimePicker control on a simple MFC dialog automatically update the current time (and maybe date in another control). I don't mind following an article if you point me there
