Listen, may i ask u another one question: is it possible to work with gif, jpeg, bmp - files(i think now u understand why i ask about 2-dimns. array), using C-language, is there libraries which allows this or only Visual C++ can solve image processing? Confused | :confused:

Well you may do raw image processing but dealing with different formats maybe difficult. There are a lot of libraries that can simplify the task, for instance, ATL/MFC's CImage class [^] or GDI+'s Image one [^], [^].

Raw image? U mean raw-data format? In my case it is not best choice. Thanks for the links.

Hi all,

I'm try to create a class to write a xml file using xmllite. I've include xmllite.h and xmllite.lib in correct place. Anyhow when I compile the following, got a compile error.

CComPtr<istream> pOutFileStream;
</istream>

Error is,

error C2143: syntax error : missing ';' before '<'
error C2501: 'CXMLWriter::CComPtr' : missing storage-class or type specifiers
error C2238: unexpected token(s) preceding ';'

How can solved this.

I appreciate your help all the time...

The compiler was complaining that CComPtr was not defined, so I just googled for it and found this page[^] (first result). If you look at the requirements section, it says which header file you have to include.
So, whenever you have such kind of error, the easiest thing to do is just google to see which files need to be included.

Get the pointer of Menu using GetMenu api, than extract teh particular menu by using GetSubMenu api, and on pointer of returned Menu class as the new button!
