Have you tried GetLocaleInfo()?

I haven't. The fact it doesn't seems to work on vista and later where I should use GetLocalInfoEx() is a problem.

But I have an exhaustive dictionary of all LCID and and their code name, much better for me! Wink | ;)

I'm not sure what you mean by this, but GetLocaleInfo() dates all the way back to Windows 2000, whereas GetLocaleInfoEx() works on Vista and newer.

Trouble with C macro '#'

#define MyTemplate( filename ) "D:/Template/MyApp/" # filename

#include MyTemplate( stdafx.h ) // failed to compile

int main()
{
cout << MyTmeplate( stdafx.h ) // ok, print "D:/Template/MyApp/stdafx.h"
}

How to include files in "D:/Template/MyApp/" if I don't copy them to my own project directorie?
solution like the macro doesn't work perhaps #include instruction doesn't accept another '#' in its statement.
Could someone help me, thanks in advance!

I recommend you have a look at Token Concatenation[^]. That explains how to define and use a C macro to concatenate tokens.

Considering you're using stdafx.h, I assume you are using Visual Studio? Why not just add the include directory to Additional Include Directories in the Project Properties dialog, under the C/C++ tab. That way, there's no need for possibly troublesome macro's and makes it easier to maintain.
For other build environments there should be similar options.

I found another trouble, I have to include the D:\template for every individual project. Is it possible to include it like "VC98\include" as an one-time-job ?

In vs2005,

1. Go to Tools->Options
2. Click on projects and solutions tree item
3. Select vc++ directories item
4. Select Include files in drop down window "Show Directories for"
5. Then add your include directory.

I think it will be same in all VS IDE.

Is m_Port a pointer?

kosacid wrote:

Why are you casting an int to a pointer? If m_Port is a global int, you'd need something like:

AfxBeginThread(ServerEXE, (LPVOID) &m_Port, THREAD_PRIORITY_NORMAL);

kosacid wrote:
int host_port = (int)param;

This does not look right. If param is supposed to be treated as a pointer to an int, you'd need:

int host_port = *((int *) param);

int *host_port = (int *) param;

Also, why are you having the secondary thread interact with a UI element? Only the primary thread (the one that owns the UI element) should do that.

it passes the param ok its not that its definitly the print function seems to be
m_Print.SetWindowText(ms_Output);

ms_Output contains say "port = 100" if i set it to 100
seems that m_Print.SetWindowText(ms_Output); cant find the edit box its pointing to 0

No surprise since you are attempting this from a secondary thread.

Where can I find atlimage.h ?

3-Jun-11 3:05

Like I mentioned earlier, you should refrain from interacting with any UI element from any thread other than the one that actually owns the element. See here for more, specifically the "Worker threads and the GUI II: Don't touch the GUI" section.

Should I understand that is not enough to find somewhere altimage.h and include in foolder project ? Because my error is :

E:\Flaviu\Temp\ImageComparator\ImageComparator\stdafx.h(44): Could not find the file atlimage.h.

it cannot be included from external source, it is the part of atl library. And VC6 doesnot contains it.

atlimage.h is found from vs2003 or maybe vs2002 and above.

you can use WIN32 way to accomplish your task.
