what is the problem you are facing. InvalidateRect adds a rectangle to the specified window's update region. The update region represents the portion of the window's client area that must be redrawn. And it gets redrawn whenever the next WM_PAINT message is received by the window. See the documentation of InvalidateRect in MSDN, that is self-explanatory.

I can assure you it is much, much more important than that. -- Bill Shankly"

I just ported one my VS 6.0 MFC Apps to VS 2005. After solving several compile errors I finally got to this error:

Error	1	fatal error C1189: #error :
  Please use the /MD switch for _AFXDLL builds	
c:\program files\microsoft visual studio 8\vc\atlmfc\include\afxver_.h	77

I was wondering why VS decided this is a dll! I checked settings and changed:

Code generation-> /MDd   to / MTd

Nothing solved. Then I tried to manually remove that definition in stdafx.h:

#ifdef _AFXDLL
#undef _AFXDLL
#endif

It's ok now. It compiled just fine, but when I want to debug, it is asking me to define an executable path! Just like when I mistakenly press debug(F5) on a dll or activex project in VS 6.0.

Can anyone help me please, how to debug an old mfc app in vs 2005?

Hi,
I am new to Visual c++ and cannot resolve follwoing problem. I have a header file (NuRe.h) that contains declaration of my main class including its functions in NuRe.cpp. I would like to use a function from a lib file in this class. Therefore I have included a lib and its header file (lm.h) in the project. would like to include following function in the class but no idea how to do that as I always get error messages.

extern int dlevmar_der(
void (*func)(double *p, double *hx, int m, int n, void *adata),
void (*jacf)(double *p, double *j, int m, int n, void *adata),
double *p, double *x, int m, int n, int itmax, double *opts,
double *info, double *work, double *covar, void *adata);

Thanks

How did you do that?

Lib files should be added to linker input list.
Are you using MS IDE? VS 6.0 or 2003 or 2005? If so, try to find: Project Properties(Settings/Options) and in 'linker' options find 'Input' and add your lib path there. Library names will be separated by a blank space. (e.g:I'm adding 2 liberariesZipArchive and HButton: .\Zip\Debug\ZipArchive.lib .\HButton\HButton.lib)

Then 'Add existing item' to your project either from right clicking in Solution explorer or project menu and select appropriate header files.

Now it's ok to include the header and use functions, however the dll must be ready when using the executable file.

I hope this will help.

Hi everybody,

i installed Visual Studio 2005, before i worked with "2003".

The project is successfully build, but at the start a get an error message :

R6034

This is an unsupported way to load Visual C++ DLLs
You need to modify your application to build with a manifest

What does it mean?

I deactivated already the generation of a manifest via the project properties/linker/manifest
But it doesn't resolve the problem Frown | :(

Many thanks in advance Smile | :)

I deleted the Debug-Directory and rebuild the whole project, then it works Smile | :)

SetUnhandledExceptionFilter Vista Problem

5-Jul-07 21:59

In my exception handler set by ::SetUnhandledExceptionFilter I report to server that app has crushed. I have to report only once. On XP everything works fine(after unhandled exception app terminates), but on Vista my application doesn't terminate after crash.
Does anybody know what's the reason?
Here the code

        ......
// Initialization

	::SetUnhandledExceptionFilter( &unhandledExceptionFilter );
        ........

long __stdcall unhandledExceptionFilter(EXCEPTION_POINTERS* exception_pointers) {

	min_crashed();		// function that reports crash								
    return EXCEPTION_EXECUTE_HANDLER;
}

Resizing Issue

5-Jul-07 21:21

Hai All,

In my project I want to load two diffrent type of bitmaps in the same controll.But my problem lies in while resizing.The controll is resizing according to the winodow and the image over it is also resizing using StrechBlt().

Now if I'm trying to load the second image of the same size of the orginal image into the streached control using LoadBitmap function,and after Invalidate() soon after that my resized contorol is going back to the intial size ,ie,a size that is less than the streached control size.

What I need is the size of the control and the image should presist the resized size of the control .

Also because of the continous redrawing of window I'm getting screen flickering.Please tell me a way to minimise the flickering effect or a way to overcome it.

Thanks In advance

What type of control?

To prevent flicker, maybe look into NOT drawing the background behind the bitmap(s).

int *buffer=new int[2000];

would it be so that memory of 2000 integers has been allocated and reserved?
or it is an array of 2000 integers type pointers.

if we want to dynamically allocate some memory i.e we dont know the array's size at compile time, and user decides to set a size at run time, what statement i should use???

A memory of 2000 integers has been allocated and reserved and the address of the array is stored in buffer.

See Here[^]. You will get some idea on how to proceed.
