Can I find what kind of controls the other window has if I have the value to it's handle?
|
|
|

Use the GetClassName() function to find the class of a control.That is if it is a edit control it returns "Edit"( WC_EDIT ).

CWnd::FromHandle
static CWnd* PASCAL FromHandle( HWND hWnd );
gives you a Cwnd pointer to the window in question ...from there i;d be looking at the help files for information about how to get pointers to child windows

Hello all. I have a DLL that is used among two different applications. So far, it was nice. However, they recently decided that the application should use some directory (for reading config files) if it is called from program "x" or other directory if the program is "y".
Now I know that with some registry flag or file (no multithread support is required) this will work. Yet I don't want to create extra files and registry keys and such.
So I was wondering, is there any way I can know which program is calling the DLL's functions? I was thinking something about some of the parameters of DllMain, but since I'm with MFC this time, I don't have DllMain, but CWinApp::InitInstance.
Any suggestion will be really appreciated.
Regards,
FG.

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,
Andy

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
