Does your edit box have the multi-line property set? FmtLines only applies if it is.

Quoting MSDN:

Windows will only respond if the CEdit object is a multiple-line edit control. 

FmtLines only affects the buffer returned by GetHandle and the text returned by WM_GETTEXT.
It has no impact on the display of the text within the edit control.

Hope that helps.

Whether it did or didn't, that would not cause a "crash." The edit control will simply ignore the EM_FMTLINES message if the ES_MULTILINE style is not set.

I have found that calling FmtLines() inside OnCtlColor causes recurrsive call to OnCtlColor. This causes stack overflow and crashes the application.
Is there any possiblity to control this?

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 defined _M_IX86

How to removing manifest entry programatically?

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?

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.
