I am setting font to menu items. For this i have set the onwerdraw property to true and implemented DrawItem.
In WndProc Procedure the lparam parameter is type cast to Drawitemstruct. This has one field as itemId which specifies the menu item id.
In windos 2000 i am not able to get this item id correctly, if the menu item has a submenu. for example if my menu is like
File Edit Search
|-------Open |-----Find
|-------New |-----Find Next
|------Close
Then it does not give itemid of file properly, some big value is assigned to itemid which is not correct. Similarly i am not getting itemid of search as well. For rest of the items Open, New, Close,Edit, Find and Find Next i am getting the correct item id and i am able to change its font and font size.
This concludes that if any menuitem has a submenu then its item id is not assigned properly. Also this happens in Winows 2000 only and in Windows 98 it shows properly. Can anybody please tell me why it is not assigning correct itemid?

hi,
1) use GetSystemMetrics to get the screen resolution without depending on which resolution you are in, then set the size to be a ratio from the screen width and height
2) override OnApply and just return
3) override OnSetActive for the property page u want to disable...
hope i helped ya

What i have now is an MFC application,that doesn't use
Document/View,and will render Full-Screen using D3D9 without any problems(Flickering etc).
When i try the same in an standard SDI application that does use the Doc/View,(View being where D3D is set up)the device fails.
If there are any members here(more experienced on the MFC side of things) that is willing to have a go,and work with me to get this working,please let me know,and i can e-mail you the code i have now.
I think this would be a very useful piece of code(or tutorial)especially for certain game programmers wanting to take advantage of some of the features of MFC,such as serialization or want to program games(Full-Screen)using MFC.
using the major search engines,i haven't found any information/examples on the net discussing or showing the setup or how to get the latest version(or even v8.0/8.1) of D3D running (Fullscreen) with a SDI MFC application.
If i get some interest/help with this,i may contribute to the site on some more advanced DX game programming subjects,for MFC,that can be built upon/extended from this base framework i am trying to build now.
Appreciate your help/answers.

There are any number of DirectX / MFC integration samples around. Google for 'DirectX' 'MFC' or look thru http://www.flipcode.com/ or http://www.gdmag.com/homepage.htm
They are all quite naive but they work. If you want to go beyond them you need to override CWinApp::Run() in your application and using a HighPerformance timer to trigger rendering threads attached to all you 3d views (at your desired frame rate).
Now that they have changed the architecture again in dx9. You would have to use the IDirect3DDevice9::CreateAdditionalSwapChain to create additional back buffers for each view etc etc
The basic issue for SDI / Fullscreen swapping is that you will need to destroy and recreate the device when changing between them.

Would it be possible for you to give me the url to one of these full-screen examples using Doc/View?
I did find some (google)that are not full-screen(i already have it full-screen,but not using the doc/view setup).
I could only find a message on the forum at www.flipcode.com where there was another guy,having the same problems as i'm having,in Full-screen mode.
There was no replies to his post though.
I don't need a 4-view(or multiple views)i already have an editor built in MFC(4-View)which runs in windowed mode.
I only need an example/help with getting a SDI application,with Document/View architecture,to run in Fullscreen mode with D3D.
Thanks for your help.

Hello.
I am having trouble using a template function with a return type of an enum as a friend of a non-templayte class. When I use the code sample (below), I get:
"error C2440: 'initializing' : cannot convert from 'void' to 'enum ENS' Expressions of type void cannot be converted to other types"
I am using Microsoft Visual C++ 6.0 Professional Edition. If anyone can shed some light on this, I would really appreciate it. 
//=============================================
enum ENS {
ENS1,
ENS2,
ENS3
};
class A;
template <class T>
ENS f(T, A *a) {
a->x;
return(ENS1);
}
class A {
private:
int x;
template <class T>
friend ENS f(T, A *a);
};
//=============================================
int main(int argc, char* argv[]) {
A a;
int i = 4;
ENS e = f<int>(i, &a); //this line generates
// the c2440 error
return(0);
}

Perhaps that's all I needed, but it is kind of weird, though.
Thank you

Hi,
I have a worker threader that sends a window message to a dialog to display the threads progress. This approach works well until the users gives focus to another application. At which point I get an access violation within the Dialogs call to UpdateData().
Can anyone offer any advice? Or does anyone know how I can detect when my MFC app loses focus, so I can at least guard against this situation happening
Cheers
Richard

hello
i need to know how could i know how many harddisk drive installed and how many partitions and there names using vc 6.0
thanks

Not sure about getting the # of physical drives, but you can get the drive letters with GetLogicalDriveStrings(), then call GetVolumeInformation() to get the volume names.

TCHAR drive[] = "a:\\";
int NoDrives =0;
for (int i= 'A';i<'Z';i++)
{
drive[0] = i;
UINT type= GetDriveType (drive);
if (type !=DRIVE_NO_ROOT_DIR )
{
SHFILEINFO fi;
SHGetFileInfo (drive,0,&fi,sizeof
(fi),SHGFI_TYPENAME|SHGFI_DISPLAYNAME|SHGFI_SMALLICON|SHGFI_ICON );
// fi.szDisplayName; Partition or drive name
// fi.TypeName Type name
// fi.hIcon Index of the icon of the drive in the system
NoDrives ++;
);
};
This should work .

I'm implementing a window in which some parts are valid drop-targets and some arent.
I've read that if I return DROPEFFECT_NONE in OnDragEnter() I won't get any calls to OnDragOver(), so I always send back DROPEFFECT_COPY.
In OnDragOver() i perform my minute-logic and return any of the drop effects, including DROPEFFECT_NONE for which I expect a 'do not do this' icon to appear next to the mouse icon.
This doesn't happen to my regret, whenever I return DROPEFFECT_NONE windows treats it as if I didn't return anything, it keeps the previous cursor.
What am I doing wrong ?
Thank you very much

I have tryed to build a static library which includes a method to show a dialog (defined in a ressource file) The linker warning I get is:
GLAP.res : warning LNK4221: no public symbols found; archive member will be inaccessible
Guess that's why the dialog never shows up when I use the generated lib in in a project.
Does anybody know what's the problem?
Is it possible to build static libs with ressources like dialogs at all?
Thanks! Constantin

You can only have one resource block in an executable. The linker doesn't know how to link two compiled resources (.res files) together.
The way I've done it in the past is to include the library's resource file in the application's resource file. See how afxres.rc is included by the MFC wizard (View > Resource Includes in VC6).

Seems as if that's the only way. Thanks!
