Use GetIconInfo(..) API to have HBITMAP from HICON...

ICONINFO IconInfo;
GetIconInfo(hIcon, &IconInfo);

then use IconInfo.hbmColor for HBITMAP...
i.e., HBITMAP hBitmap = IconInfo.hbmColor;

Make sure to delete those bitmap handles as..
DeleteObject(IconInfo.hbmColor);
DeleteObject(IconInfo.hbmMask);

First of all, posting your entire application and asking someone to finish it for you isn't going to work. We're here to answer questions, not complete your application for you.

Second, when you post code, either use the <pre> tag, or make sure the "Ignore HTML tags in this message (good for code snippets)" check box is checked.

Try asking a more specific question. Since you said you have been working on this 'for days', start out by telling us what you tried, and why it didn't work.

how to call dll's in your code in VC++

I m the beginer in the world of VC++. I m like a 1 month old baby in this world of VC++.
I want ask u all a very basic question ie. how to call an already created dll in ur code.
I m actually developing an interface between AutoCad n SAP.
AutoCad provides runtime extensions called ARX.
Object-ARX is an API and they r a kind of dll's which r to be used to programm ur Autocad Appllication.
So start with this project of mine I very first need to understand how to use dll's in ur code.

They are dll's or a 'kind of dll' ? If these files are not dll, then you cannot use them as if they were dll. It is either black or white, not 'a kind of'. You have to be sure of that before going any further.

namy31 wrote:

That's not a basic question. Playing with dll is kind of tricky if you don't have a lot of experience (and 1 month programing in C++ is very very small). There are a bunch of articles here[^] that you can have a look at. Just to have a litle bit more knowledge about what is a dll.

A question now: what do you have exactly ? A dll file, but is there a .lib file and header file supplied with it ?
Or you just have the dll alone ? In that case you will need to know exactly the names of the function names and their prototypes (that is, the number and the types of the arguments of your function)

I'm trying to execute my program that uses the -Registry Wrapper Class (CRegistry)- object.
I included the Registry.h file.
But it gives me an error which you can see on the picture below:
