I have created the dll project, this dll needs other two dll, and

I want to finally provide only one dll(the one generated from this dll project, and hopefully the other two dll can merge in this dll),how should I do?

It seems the directly genrated dll is not ok.

no.

this problem really make me annoying.
do you have any suggestions.?

SandipG 2-Jun-08 1:22

2-Jun-08 1:22

No then you cant merge them in to one dll no sugessitions also
you have to distribute three dlls.
Just check incase if these dlls support static linking like MFC then you wont need to distribute all dlls.

Sandip.

USE oldMemState.DumpAllObjectsSince(); to find which all objects are leaking.

If you use the debugging version of new then you can get file/line number
information that can help you find the line of code making the allocation(s)
that aren't being freed.

Add something like this to the top of all your source files...

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

Well see this code

Mynamespace.Myclass.MyMythod a=new Mynamespace.Myclass.MyMythod();

but if you use of #using you will have this code:

#using Mynamespace
Myclass.MyMythod a=new Myclass.MyMythod();

I have created the Test SDI application with MfcAppWizard(exe).

I run the appication an it's showing me default window.

It has default window color as RGB(192,192,192). But I want to change it to some different color for better look.

How can I change it's defauld color for my application so that all window forms, dialog boxes, tool bars, menus, etc having some new default colors like sky blue or somthing else.

Please help me regarding this.

I guess you have to handle it separately for every window by handling WM_CTLCOLOR.
