GetModuleFileName() will return the name of the executable( the HMODULE should be passed as NULL ). So I think with this you can distinguish the exe.

Yep, worked perfectly, thank you.
Might add that I thought on that function, but also thought that it would return me the name of the DLL...

hi, i wrote a multithread MFC dialog,
in my CMYTESTDlg class,i declared a static thread function and several static variable like param1.
the thread funtion uses the static variable, but i got error lke this during linking:unresolved external symbol "public: static long CMyTestDlg::param1"
(if i don't use static variable, the error will be something like illegal refernce)
what's gonig on? and how do i fix the error?

You have to initialize your static variables.
<br />
long CmyTestDlg::param1 = 0;<br />
|
|
|
|
|
i think i did initialized the variables,
here is my thread function
UINT __cdecl ThreadFunc(LPVOID pParam){//AfxBeginThread(ThreadFunc, this);
CMyTestDlg* me=(CMyTestDlg*)pParam;
me->param1 = 0;
....
}

You need to define the static variable, as Cyrilix showed (outside of the class declaration).

if param1 is static variable you should call it like this
CMyTestDlg::param1 not me->param1. as static variable not linked with object

Hi,
I got an activex control which works fine in debug build but the same is showing 'memory not enough' problem in release mode.
Please advice.
Thanks in advance.
Regards,
John.

Probably start with all the compiler and linker settings and their differences.
You can also have debug info attached in a release build and run it in the debugger.

If i tick on the 'Generate debug info' in the Project>Settings>Link for the release setting i cant set up a break point. It will get disabled.

Thanks for your attention.

Do you have debugging info turned on for the compiler as well?

Please can anyone tell me how to get and change the contrast/colour/brightness of the screen in C++/MFC.
TIA,

The first thing to figure out is how to do it without code. From there, you can start searching through a smaller set of APIs.

Hi,
I'm not sure what your getting at, without code I'd just do:
Display properties->Settings->Advanced->Color and change it there
However searching for these just brings out code which changes the display settings for the app rather than the actual settings in windows.

That's exactly what I was getting at (which will become clearer in time). However, I have a Color Management tab, and on that tab I see nothing for screen brightness, color, or contrast. Do you have something different?

In addition to the Colour Management tab I have a Colour tab which allows me to manually change the settings.
ok so far I've tried:
CDC *win = GetDesktopWindow()->GetDC() ;
COLORADJUSTMENT col_adj ;
win->GetColorAdjustment ( &col_adj ) ;
col_adj.caBrightness = 100 ;
int err = win->SetColorAdjustment ( &col_adj ) ;
this does return the correct settings for the system however the Set method doesn't actually change anything *that I can see* so I'm assuming I'm looking at the wrong area and changing the wrong settings

Since I cannot reproduce this, you'll need to find which registry keys are changed by the controls on the Color tab.

You can use GetDeviceGammaRamp() and SetDeviceGammaRamp() to change monitor brightness on videocards that support it. More information in the MSDN: http://msdn2.microsoft.com/en-us/library/ms536529.aspx[^]
All you have to do is call GetDeviceGammaRamp() and iterate through all 256 WORDS and increment them. Higher values == higher brightness.

Is it possible to display a small image on a button? Together with a text?
Is it possible in VC++6?
