Why are you calling FmtLines() and GetWindowText() from within the WM_CTLCOLOREDIT handler?

Are you using UNICODE in your build? There are some items within the CommonControl 6.0 that are only capable of operating with a unicode build, so perhaps that is your problem.

Try a simple test app - set for unicode - and see if it works, then modify to MBCS instead of unicode and try again.

Hope that helps.

I tried with test application.
It crashes in unicode build and in MBCS its ok.
However if add the following manifest then it crashes in MBCS also.

#if _MSC_VER >= 1400

	// Determine the Processor Architecture:
	#if defined _M_IX86
		#define PROCESSOR_ARCH "x86"
		#define CC_PROCESSOR_ARCH "x86"
	#endif

	#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='" CC_PROCESSOR_ARCH "' publicKeyToken='6595b64144ccf1df' language='*'\"")

#endif // _MSC_VER >= 1400

The following manifest entry causes some problem in common controls like list control, edit box. etc (Vc++ appln).
Its getting added when i use some third party libraries.
How do i solve this problem?

// Determine the Processor Architecture:
#if defined _M_IX86
    #define PROCESSOR_ARCH "x86"
    #define CC_PROCESSOR_ARCH "x86"
#endif

// Common Controls
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='" CC_PROCESSOR_ARCH "' publicKeyToken='6595b64144ccf1df' language='*'\"")

you can also use external manifests, so in the project settings the manifest will be changed.

is _M_IX86 defined?

Re: How to removing manifest entry programatically?

KarstenK29-Sep-09 20:27

the #pragma is a precompiler dirrecte which in this case will inject a manifest. To avoid it comment it out.

since #pragma is defined in thirdparty files, we cannot modify them.
May be we need to do it different way.
Is it possible to remove that #pragma by programatically? Or by some settings in our application?

Maybe modiying the code or copying the interesting parts in a separate file.

#define _M_IX86 in the project settings or in the stdafx.h like "#define _M_IX86 1"

Can't you use the Microsoft manifest tool[^] to modify/remove the manifest? Another option is to call the SetWindowTheme Function[^] on the affected controls. Maybe call it on all child windows?

SetWindowTheme(m_YourControl.m_hWnd,L"",L"");

Although this seems more like a hack.

Hi,

I am very new to VC++ and I got to work in VC++. My requirement is to call dll from an exe and I need to pass some value to the dll. I need to use that value in the dll.

I am using LoadLibrary method to invoke the dll. But how to pass a value and how to use that value in the dll. Please help me.

for example:
LoadLibrary("test.dll", "display this text");

On load of dll (::OnInitDialog()): i want to display the message "dispay this text".

How could I do this. Please help me out in this.

Thanks in Advance,

There's no such concept. DLLs contain exported functions. You first have to load one of those functions (via GetProcAddress()) and then pass arguments to it.
