See here[^] for all the information on how to manipulate icons in your code.

By "memory data", do you mean pixels? If yes, you could try creating a DIB section using CreateDIBSection[^], then render your icon onto this bitmap. Since CreateDIBSection gives you a pointer at the pixel data, you can then use that. Note that this solution will (probably) loose the alpha channel in case you need it. Otherwise, i believe the icon file format isn't that complicated, you can try to load it yourself to get access to the pixels.

as you guess, it means pixels!
can you give some steps for using CreateDIBSection?
|

I'm not sure what you mean by steps, but...
Fill out a BITMAPINFO[^] structure (meaning, the BITMAPINFOHEADER[^] struct in that), specifying your requested width and height, color bit depth (i recommend 24 or 32), also don't forget to set the biSize member to the size of the struct, biPanes should be 1, the rest can be zero i believe. Then feed this struct to CreateDIBSection, something like this:
CreateDIBSection(NULL, &your_bitmap_info_struct, DIB_RGB_COLORS, &pointer_to_pixel_data, NULL, NULL);
This will give you a HBITMAP handle and also set the pointer_to_pixel_data pointer to point at the very first pixel. Of course if it succeeds.
Then you can create a DC, select this bitmap into it and use DrawIcon[^] or DrawIconEx[^] to render your icon onto the bitmap. After this, you can use the pointer_to_pixel_data to access the pixels and do whatever you like with them. Don't forget to clean up the bitmap and the icon after you are done with them. Good luck.

Hello,
How to get system default font?
|
|
|
|
|
Hi,
You can use GetStockObject() [^] function to get the default system font.

But MSDN says "It is not recommended that you use DEFAULT_GUI_FONT or SYSTEM_FONT to obtain the font used by dialogs and windows".
Then what to use?

Yes, that is why i said "You can use...". In your initial post have asked about default windows font, but in fact system uses several fonts: menu font, message box font, icon label font, caption font, status bar font...
MPTP wrote: Then what to use?
For best precision you should use the SystemParametersInfo()[^] function with the SPI_GETNONCLIENTMETRICS parameter to retrieve the current font information.
This method will fill a NONCLIENTMETRICS[^] structure and you can check the:
LOGFONT lfCaptionFont;
LOGFONT lfSmCaptionFont;
LOGFONT lfMenuFont;
LOGFONT lfStatusFont;
LOGFONT lfMessageFont;
fields of this structure. I hope this helps!

Hi,
What is method to change the build from VS6 to VS2008.
|
|

If you open the solution with vs 2008, you shall be automatically guided.

Is there any method?

Then you need to keep both your VS systems!
|
|
|
|
|
The conversion wizard will preserve your .dsp and .dsw of visualC6 and create new ones for vs2008.

Will it degrade the performance of application?
|
|
|
|
|
This has nothing to do with performance. It will simply convert your .dsp and .dsw files to .sln and .vcproj. If there are no conversion errors you will be able to recompile with vs2008.

Rename the VS6 solution files to *2008 and open only them with vs2008 so you have the original vs6 files to open in vs6.

I understand your concerns, but I need to tell you that this particular forum is ONLY for asking C/C++/MFC queries.

Yes i m creating my application on MFC,this is a SDI type of document.
available controls have not such type of control.so i m just not understand what control are required for designing the ID cards.
