LPCSTR is a const char pointer. Why do you want to remove the const ?
When asking a question, please be specific and tell exactly what you are trying to do. So, in which context do you want this conversion ?

if (and only if) you have this requirement because of a bad designed function prototype (and you cannot change it, e.g. you have a third party DLL), i.e. a function that in fact doesn't change input buffer but accepts char * as argument, then you can simply cast the pointer.

If u have compiled your program with UNICODE and _UNICODE defined, then LPTSTR will automatically become LPWSTR (Long pointer to a wide string) u cant assign this to char* but u can assign this to a variable of type wchar_t*.

after using wchar_t* use swprintf() to get proper output.

ohh sorry then If you use T2A macro, it will work in UNICODE and MBCS.
please go through T2A macro

Why would it be usefull to use the T2A macro ? A LPCSTR is a const char*.
I think you should read some documentation about the different string types to better understand the different namings.

Probably because the compiler complains about the constness.

For button bitmaps in an MFC toolbar, you can use a masked
imagelist to hold the bitmaps.

    // in constructor
    // transparent color is bright green
    m_ToolBarImageList.Create(IDB_BITMAP1, 16, 1, RGB(0x00,0xFF,0x00));
...
    // some time after m_ToolBar's is created
    m_ToolBar.GetToolBarCtrl().SetImageList(&m_ToolBarImageList);

Message Mapping Problem

I wrote a class CCamCtrl. I use a Custom message WM_CAPTURE_IMAGE and used message mapping. A dll is to post message. I think dll does not post messsage, sothat OnCaptureData(WPARAM wParam, LPARAM lParam ) event can't be called.

Are there any problem in my code or in dll.

here i mention that dll works well for dialog based application.
Can anyone help me?

Thanks in Advance
