Re: Has Anyone ever had D3D Running FULLSCREEN in a SDI App??

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.

Enum problem

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. Wink | ;-)

//=============================================
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);
}

Odd... it works for me when I move the class A definition above the f() definition.

UpdateData() and worker thread

AJ12312-Oct-03 5:24

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

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 .

Er, how is that any different from GetLogicalDriveStrings()? and that still doesn't tell you how many physical hard drives are present.

COleDropTarget::OnDragOver(), windows ignores my DROPEFFECT_NONE

ohadp12-Oct-03 1:55

12-Oct-03 1:55

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

Possible to build static Libs with Ressources?

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).

How to read a file line-by-line?

Is there an easy way to read a file line-by-line, not using MFC? I looked at fread, ReadFile, and ofstream, but I couldn't find a "ReadLine" function in any of them.

Thanks!

You can use getline()

#include <fstream.h>    

void main()
{
  char buffer[256];
  ifstream file;
  file.open("c:\\autoexec.bat", ios::in | ios::nocreate);

  if (file.good())
  {
    while(file.peek() != EOF)
    {
      file.getline(buffer,255);
      cout << buffer << endl;
    }
    file.close();
  }
  else
    cout << "error opening autoexec.bat" << endl;
 


 }

the default delimiter for getline is \n, see msdn for more details.

Hope this helps

One solution is std::getline().
