i had already post some related code.

Can you tell me simple why these type of think happen?
I think possible solution is Invalidate or RedrawsWindos.
But i want to know why these type think happen?

you are not doing any paint code for that. All you do is simply create a child dialog and set up a timer. I can't find any possible issues in this in order to make the controls diasappear. Thats why i suspected your code. Hmmm | :|

Ok you try those possible solutions.

Call ShowWindow(SW_SHOW) before centering it.

Uhhhh!!!! Header problem after installing (and uninstalling) VS2008 SP1.

My little application was compiling fine as is until I installed the VS2008 SP1 yesterday. I mean it compiled fine, then I installed the update, then I recompiled and started getting the following error:

1>------ Build started: Project: GTRNoteWorker, Configuration: Release Win32 ------
1>Compiling...
1>GTRNoteWorker.cpp
1>Automatically linking with ToolkitPro1321vc90S.lib
1>C:\Program Files\Microsoft Visual Studio 9.0\VC\include\xtr1common(252) : error C2766: explicit specialization; 'std::tr1::_Is_integral<int>' has already been defined

1>GTRNoteWorker - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

So I think OK, they tightened up something, so I checked to make sure I haven't included the header somewhere else ...then I realized that the error is stating that the thing has been defined already IN THE SAME HEADER file!

I think I must be missing a define or something Mad | :mad:

Any help would be appreciated!

Thanks,
Paul

You could prevent a header file from being included twice with a simple check:

#ifndef MYHEADER_H
#define MYHEADER_H

// Insert your existing header content here
#endif

If this doesn't help, the error is indeed in the header content itself rather than a result of counting it twice. To give any assistance with that, you'll have to post it here Smile | :)

Hi, Thanks for your suggestion!

The header file is rather large and is part of VC9, C:\Program Files\Microsoft Visual Studio 9.0\VC\include\xtr1common.h. After doing a Google search, I see that MS implemented a new specification in SP1 and a lot of people are getting these "explicit specialization" messages. I won't call them errors since I probably am missing something, however I'm just going to uninstall VS2008 and re-install it without SP1. At least the application could be compiled, and run before SP1 ...I just don't have time to track this down or learn the new requirements at this point.

Thank you again,
Paul

Well, I finally tracked it down. It makes NO sense to me but after I changed the order of the header files, I got an error specifying there was not enough memory to compile the resources - the message suggested using the /Zmxxx option which I did. This got me passed the errors and such. I did get another unrelated error at the step of embedding the manifest file: Mt.exe not found. I searched for the exe and it was not in the bin folder (where I assumed it was before installing SP1) sooo - I pointed the search path to use VS2005's MT.EXE. What a mess, but it compiles and runs now!

just go to the resource file , you see the menu items. change then name there. recompile and run Smile | :)

SetMenuItemInfo[^] allows you to change a menu item by handle. This would be useful if you don't have access to the resource file or if you want to use an if/else block to decide how to change the menu.

TCHAR to LPTSTR

Please help... Confused | :confused:

use MultiByteToWideChar and WideCharToMultiByte functions.

see http://msdn.microsoft.com/en-us/library/dd319072(v=vs.85).aspx[^]

or you can use mbstowcs etc functions.You need to set locale before using it( setlocale )

see http://msdn.microsoft.com/en-in/library/k1f9b8cy(v=vs.80).aspx[^]

I hopes you know what a TCHAR is. if you application type is multibyte TCHAR is char , otherwise wchar_t

If u can Dream... U can do it

What do you mean by convert?

TCHAR* is merely a pointer to a char or wchar_t depending on the definition of UNICODE. LPCTSTR is a typedef to const TCHAR* so no conversion is necessary; but you may need a cast to satisfy the compiler.
TCHAR is a single character so cannot be converted or cast to LPTSTR; if you actually meant TCHAR* then both expressions evaluate to the same thing: a pointer to a character or wide character.

Thanx, my one doubt is cleared, about TCHAR to LPTSTR

My Program deals with UNICODE only

a small example will very helpfull for me, of how to convert TCHAR* to LPCTSTR and LPTSTR.

Thanx in advance.

There is no conversion involved; as I said in my previous post TCHAR* and LPTSTR equate to the same thing, a pointer to a string (character array). LPCTSTR is the same as const TCHAR*, a pointer to a string constant.

TCHAR* to LPCTSTR is a simple typecast

TCHAR* pch;
LPCTSTR pcch = (LPCTSTR)pch;

TCHAR to LPTSTR is an address of operator

TCHAR ch;
LPTSTR pch = &ch;

Re: TCHAR issue

LPTSTR __stdcall gHelp(TCHAR value)

	pch = &value;
	return pch;
}

compiler gives warning

You will also have a problem that you are returning a TCHAR* to a TCHAR value, not an array (i.e. string). Do not do this or you will end up with memory overwrites and/or invalid data.

As to your compiler warning, you must have a definition of gHelp which reads something like:

LPCTSTR __stdcall gHelp(TCHAR value);
