Nothing is dificult about changing the user interface as long as
you know where to look in the MFC help
the background color of a dialog can be easily changed in
WM_CTLCOLOR
look for CWnd::OnCtlColor in the help.
MFC is not as easy as VB and Delphi but it gives you more control over
your application

|
|
|
In your CProjectApp.cpp do:
SetDialogBkColor(RGB(0,0,0));
This would change the dialog background to black
To use an image you can use BitBlt.. if you need help with it let me know

BUT is it possible to do the same using WTL (no MFC) .. how ??

Look in your view class's header file and see if you are deriving from CScrollView.
If so, change to derive from CView instead.
You may have to clean up some functions that no longer apply -- the compiler will let you know.

I've looked around for some example code for how to add a button ( or any other control) to a custom control
which is based on a CWnd. All the examples are for adding buttons and stuff to dialogs. which is simple and easy
and I'm sure this is to - i just want to get it done the right way.
CButton m_Button;
m_Button.Create( ...?
...?
what is needed? (not useing a dialog)
thanks

I'm not sure what it is you wish to achieve? A composite control that consists of a button and something else? Where you create that button will also depend on which you parent is going be. Pleas give a little more information.
Happy programming!!

I hate to say this, but I don't understand how the documentation could be any clearer on this.
m_Button.Create("OK", WS_VISIBLE|WS_CHILD, CRect(0,0,100,100), &m_the_control_i_want_as_parent, THE_ID_I_WANT_TO_USE_FOR_THIS_CONTROL);
About the only two things in there that might be confusing are the styles, (which need only specify that the control should be shown (WS_VISIBLE) and that it's a child control (WS_CHILD)) and the ID, which usually MSDev creates for you. You just pick and ID that's unique to this dialog and use it.
Now, this should work fine as long as the control you using as a parent doesn't blit over you with drawing code.

Anyone know where or how I can get hold of the AVI that gets played when say a help file is first open and the index is created. The one where a pen writes in a book.
Thanks

Use the Win32 API GetComputerName:
TCHAR pBuffer[61];
DWORD dwSize = 60;
GetComputerName( pBuffer,&dwSize);

Hi,
I have made a dialog based MFC application which I want to download using the <object> tag in IE as if it was an ActiveX control. This works just fine, but does anyone know how to read the
<param name="aaa" value="aaaa">
tags within the object tag?
<object id="myapp" codebase="myapp.exe#-1,-1,-1,-1">
<param name="aaa" value="aaa"> <-- I need to read this tag from my app.
please ?
regards,
Martijn.

hello,everyone.
I want to handle WM_MOUSELEAVE message in my vc6 program,so I use a function named _TrackMouseEvent;below is my code:
TRACKMOUSEEVENT tme;
::ZeroMemory((void *)&tme,sizeof(TRACKMOUSEEVENT));
tme.cbSize=sizeof(TRACKMOUSEEVENT);
tme.dwFlags=TME_HOVER | TME_LEAVE;
tme.dwHoverTime=500;
tme.hwndTrack=hWnd;
::_TrackMouseEvent(&tme);
but I get the error message:
error C2065: 'TRACKMOUSEEVENT' : undeclared identifier
my project type is win32 static library,and I do not change any preprocessor definition,and I have already included stdafx.h.
thx for any suggestion.

I used WM_MOUSELEAVE in my Calendar see -> http://www.codeproject.com/miscctrl/coolcalendar.asp
Looking quickly at the code every thing looks well. I've checked MSDN and the requirements are good:
Windows NT/2000: Requires Windows NT 4.0 or later.
Windows 95/98: Requires Windows 98.
Header: Declared in Winuser.h; include Windows.h.
My gut feeling suggests your using Win95, am I right.

I have two windows that must contain the same dialog, i other words, I have to show twice the same dialog with different data, this dialog it's used as a summary of the machine status for the user.
I've declared two variables of the type CMyDlg, then I use the Create member f(x) passing as a parameter the ID of the dialog resource, and finally I show the window.
In this way it seems that the dialogs use the same class and the same data too, I don't know if I'm working correctly, could you help me?
Thank you in advance.

I've been running into a strange problem when stepping through c++ in Visual Studio.
It goes like this:
I write some new code in a file. I set a breakpoint at the code I want to evaluate. When i start the debugger it tells me that the breakpoint is in an invalid location and disables it. The debugger then breaks at the start of execution.
If I then run to cursor to a specific location, the break occurs at the wrong line or on a blank line. If I then step through the code, new code that I've added doesn't seem to get executed even though I watch the execution pointer step right over the new lines. New variables that I declare within scope of the breakpoint still shows up as undefined in the watch window. Its as if the debugger is "out of sync" with my code.
I've tried cleaning and rebuilding the project. That hasn't worked, so I'm unsure what to check next... Anybody else had this happen to them and if so how do I fix it?
Thanks,
Josh

I have run into this problem quite a few times. And the reason i believe this happens is
IF the code that is being debugged by VC DOES NOT match what you have just built. Maybe the Visual studio picks the application from a different file location than where you are building your application project. The solution is to findout from where the debugger picks the application from And then to copy your new version(with your changes) to that location and start the debugger.
I Hope this helps.

I experienced a problem similar to yours a couple times.
One time, I was calling DLL built using a release build.
Another time I overwrote memory with a bad pointer. I guess I was overwritting the code stack.
Please make sure your links and defintions in the project settings are OK. Also examine the stepped code in the debugger just before things go hay-wire
Hope this helps.

I have also seen this problem quite a bit. There are actually two separate issues, I think. One is the disabling of the breakpoint and then breaking at the app entry point; the other is the failure to execute new code. I say they're separate because I've seen each individually and cured them separately.
The solution for the first thing has always been to stop execution at the bogus break and go to the file where the breakpoint is now disabled. You'll see a hollow circle there. Position on the line and press F9, and the circle becomes filled again. Do I trust it? No, I hit F9 two more times to clear it and reset it again. I don't know if it's necessary, it's my voodoo and I just do it and it always works.
The second problem has happened to me many, many times in VC5 and VC6. The environment loses track of which files need compiling and linking and simply builds a mutant hybrid of the old and new code. You're &^$%@!* lucky when you see it in the debugger, otherwise it can show up as a bug in operation. One that doesn't make ANY sense unless you put it in this context. I have ALWAYS been able to fix this with a Rebuild All. ALWAYS. IMO, you can forget about incremental compilation and linking when it comes to your final release, end of story. I do a Rebuild All periodically. Not everyone has that luxury; but then, I don't know of anyone who has the luxury of putting out a program that crashes all the time, either.
Incidentally, something that will hose you in the same fashion is if the system clock gets set forward or back then forward while you are coding. Really confuses the IDE.

Hmmmm...
I'm still stumped.
When I try to set a breakpoint or enable a breakpoint(hitting f9) the IDE tells me "cannot set breakpoint at cursor location".
I've done a Rebulid all many times now(this is no small project I'm working on so it takes quite a while) to no avail.
I also have removed all optimizations and other funky compiler options to try to fix the confusion....
I guess this is the part of the development process that they never tell you about...
Thanks anyways
