Hello Guys,
I have list control on a dialog box. When i click a header(column name) of the list control it should be sorted(ascending or descending) autimatically. Is there any property to set this or i need to write this sorting logic itself ? Please reply soon if you guys know this it's urgent. Thanks!

I think you should overwrite the HDN_ITEMCLICK default routine from CListCtrl; that will give you the header item selected in LPNMHEADER phdr = reinterpret_cast<LPNMHEADER>(pNMHDR); m_nSortHeaderItem = phdr->iItem; After that you do the 'sort' thing and display the new list. This is how I did it! Good luck and keep the good coding!

The List Control doesn't have any styles for doing this automatically, but you can handle the HDN_ITEMCLICK notifications and use SortItems() on the list control.

Depends of what the code is. Is it simply source files ? If yes, you can simply add them to your project.

I suppose you are speaking about a splitter window ? Take a look at the MSDN[^] for more details (or search on this website, I think there are some splitter controls here also).

how to integrate two solutions in one project......
with mutual dependency
|
|
|
|

i think you mean two projects in one solution...
|
|
|
|
|
Unless the two projects are statically linked libraries (.lib), mutual dependency is a bad thing. Avoid it at all costs.

I already looked all over for very simple editor that only to be run in ms-dos box.
it should use FILe* studio for opening and saving text files.
I just need sample or example.

|

I don't understand what you are looking for . You want a text editor ok, but what has MFC to do with that ? Take for example notepad, it is a very (very) basic text editor, so what is the problem with this one ?

Uuuuhhh ??? What do you mean.
Or maybe you want to have the sources code of a text editor ?

Hi,
In my application I need to draw a predefined bitmap into a rounded
area , but the CDC::BitBlt(...) allows me to draw the bitmap into
a rectangular area only.
Is there an API to draw a rounded bitmap?
If not - should i use the CDC::SetPixel() and CBitmap::GetPixel() instead?(I need to refreash the screen every 70msec...)
With best regards,
Eli

In theory, that's simpler to do it with CRgn class member methods. Good luck and keep the good coding!
|
|
|
|
|
First , thanks for the (very) quick reply .
I thought about the CRgn option,but i couldn't find a function to draw to the created region....
Regards,
Eli

You would use the region as a "cookie cutter" to trim the bitmap (which is square).

Hi Steve,
I know how to create that region , but how can I draw the bitmap into that region?
Regards,
Eli

Thanks , it's working

MaskBlt() was created for exactly this purpose. Specify DSTCOPY as the background ROP and you'll be right.
Alternatively, you could create a region and select it into the destination device context as the clipping region (SelectClipRegion ) and just use a normal BitBlt() of the full area.

How should CAD primitives draw such as lines, circles, polygoan,splines,arc etc. using Visual C++/ MFC, For two dimensional drawing and how it convreted into Three dimensional view. Shall code is avilable for doing so.
|
|
|
|

Dude,
Probably you dont know VC++. Get a good book and learn.
Contact Device will enable you to draw.
Try OPENGL too.

Reposting you question won't help. What is the problem with the things we suggested previously ?

Hi.
I've been using the crtdbg functions for a while to find memory leaks, and it works great when I use the following preprocessor statements.
#ifdef _DEBUG
#define _CRTDBG_MAP_ALLOC
#include <crtdbg.h>
#define DEBUG_NEW new(_NORMAL_BLOCK, __FILE__, __LINE__ )
#define new DEBUG_NEW
#endif
As you'll know, this way the crtdbg functions show the correct file and line where the memory of the leak was reserved, using the "new" operator.
The problem is that, if I want to use the "new(std::nothrow)" in my programs, I need to include the "new" library, and that creates a conflict with the "new" redefinition, causing the "nothrow" to be an undeclared identifier. Of course, if I comment the #define new DEBUG_NEW macro, the program compiles and runs great, but all the leaks are referenced to crtdbg.h file.
Anyone has a solution for this?
Thanks in advance.
