Hi,
in this example i need a WDK installed, is this right?
Because VS 10 don't know a "NtQueryInformationFile" and i found on microsoft.com that i need "ntifs.h" to include for this? After all ntifs.h is on my system but now i can't find "windowsfamiliy.h" 
Best wishes

This is the wrong place for questions like this; why not try it yourself.

I've 2 nvidia video cards installed on my computer.
And each video card has 2 heads.
So I've got 4 monitors/displays:
display1 & display2 from card 1.
display3 & display4 from card 2.
Now I want to run 2 fullscreen|exclusive DirectDraw applications. each app bind to a different display.
e.g. App 1 bind to display 1 (card1)
App 2 bind to display 3 (card2)
I want to know if this is possible?
because now I am getting DDERR_EXCLUSIVEMODEALREADYSET while trying to SetCooperativeLevel in the second app.
but it's no problem if I run only one app, and bind to any of the 4 displays.

Fullscreenmode in DirectX is always exclusive mode.
The only way I know, is to open two windows that are fullsize without titlebar and min-/maxboxes.

Hey there
I have a C++ Windows application using Win32 API's. User can select a control (buttons, text box, drop down...) via using the TAB button on the key board. By default Windows does a drawing by which the selected control looks selected, but is it possible to make it more visible by a color change?
i.e., when the user selects a BUTTON can i make the color of the button change to blue or orange or something like that, thus giving a visual feeling that this is the control that's selected.
BTW, this is a Win32 API app, so which windows messages i need to check for this and make changes?
Thanks in advance

There is no simple way to do this.
With some controls this may be achieved by changing the text and background colors.
For full customization you must use owner-drawn controls handling the WM_DRAWITEM notification.
You may browse the articles here for some examples (especially buttons[^]), but most of them are using MFC and not Win32.

There is a class A, in a outside library. Now I want to use the way of explicit load librar. I know that it needs to use LoadLibrary to load the dll and use the function GetProcAddress to get the function pointer if use outside function. But how to use the outside class.

Hi,
I am trying to print the content of the CRichEditCtrl. The problem is that when I want to use pagination (with A4 pages), the printed text (which is just 4 sample line with 40 chars at most) at the code
lTextPrinted =FormatRange(&fr,TRUE); is always lesser than the actual text pointed by the lTextLength variable making the loop run for ever. What is the problem with the following code ?
CPrintDialog printDialog(false);
if (bShowPrintDialog)
{
int r = printDialog.DoModal();
if (r == IDCANCEL)
return; }
else
{
printDialog.GetDefaults();
}
HDC hPrinterDC = printDialog.GetPrinterDC();
CDC pMyPrinterDC;
pMyPrinterDC.Attach(hPrinterDC);
FORMATRANGE fr;
int nHorizRes = GetDeviceCaps(hPrinterDC, HORZRES);
int nVertRes = GetDeviceCaps(hPrinterDC, VERTRES);
int nLogPixelsX = GetDeviceCaps(hPrinterDC, LOGPIXELSX);
int nLogPixelsY = GetDeviceCaps(hPrinterDC, LOGPIXELSY);
LONG lTextLength; LONG lTextPrinted;
SetMapMode ( hPrinterDC, MM_TEXT );
fr.hdc = pMyPrinterDC.m_hDC;
fr.hdcTarget = pMyPrinterDC.m_hDC;
long lPageWidth = ::MulDiv(pMyPrinterDC.GetDeviceCaps(PHYSICALWIDTH), 1440, pMyPrinterDC.GetDeviceCaps(LOGPIXELSX));
long lPageHeight = ::MulDiv(pMyPrinterDC.GetDeviceCaps(PHYSICALHEIGHT), 1440, pMyPrinterDC.GetDeviceCaps(LOGPIXELSY));
CRect rcPage(0, 0, lPageWidth, lPageHeight);
SetTargetDevice(hPrinterDC,lPageWidth);
fr.rc = rcPage;
fr.rcPage = rcPage;
fr.chrg.cpMin = 0;
fr.chrg.cpMax = -1;
this->FormatRange(&fr,TRUE);
DOCINFO di;
ZeroMemory(&di, sizeof(di));
di.cbSize = sizeof(DOCINFO);
di.lpszDocName = "GnosisExplorerNotes";
di.lpszOutput = NULL;
RECT rcClient;
GetClientRect(&rcClient);
DisplayBand(&rcClient);
StartDoc(hPrinterDC, &di);
lTextLength = GetTextLength();
do {
StartPage(hPrinterDC);
lTextPrinted =FormatRange(&fr,TRUE);
DisplayBand(&fr.rc );
EndPage(hPrinterDC);
if (lTextPrinted < lTextLength) {

fr.chrg.cpMax = -1;
}
} while (lTextPrinted < lTextLength);

I ended up that the RichEditCtrl version 2 causes this problem.
Using RichEditCtrl version 1 it works fine.
Any solution ?
I am attaching the source code. Please check that the lTextPrinted is always lesser than lTextLength.

Thank you Andrew,
The offending code was the
GetTextLength()
that it should be changed the way you showed me in your example with :
lTextLength = GetTextLengthEx(GTL_PRECISE | GTL_NUMCHARS);
I didn't bothered until now, with the GetTextLengthEx and I had a really hard time with this functionality. Now it works that way it should be.
MSDN reports :
GetTextLengthEx provides additional ways of determining the length of the text. It supports the Rich Edit 2.0 functionality. For more information, see About Rich Edit Controls in the Platform SDK.
My very best regards for your help,
George

Hi,
I am using H.264 codec to create MP4 file from images. IMFSinkWriter is used for encoding purpose.
While encoding, I need to control the quality of the encoded video by adjusting the average bit rate parameter value. But I could not get any equation for calculating this.
I tried several equations, but the video behavior is different for different type(resolution) of images.
One of the equation used is Frame width * Frame height * frame rate * Image quality parameter * some constant.
But this is not working for all types of resolutions.
My image quality parameter will be varied from 1 to 100.(Low to High)
Could you please provide an equation to calculate the average bit rate for controlling the image quality from Frame width, Frame height and frame rate?
I tried the VBR encoding but it does not work for the encoding using Sink writer.

I have a buffer which contains BitmapInfo + pixel data. this pixel data is in the palette format. Bitmapinfo structure contains color table. This can be solved by using LockBits method but I don't know how to use LockBits method for converting buffer to buffer. I found a lot of such conversions, but they are mainly processed one input file.
|
|
|
|
|
Here[^] you find how to reach the color table.
Pixel info follow the color table itself.

Hi have a good day,
Does any body manage to Build application using Dialog Resource for windows 64 bit ?
It Didn't Work for me , I get this error :
error C2664: 'DialogBoxParamW' : cannot convert parameter 4 from 'BOOL (__cdecl *)(HWND,UINT,WPARAM,LPARAM)' to 'DLGPROC'
I try to change
BOOL CALLBACK DialogProc to
INT_PTR CALLBACK DialogProc
But I still get ,
conversion from 'INT_PTR' to 'int', possible loss of data.
I also try to edit , winuser.h , From
typedef INT_PTR (CALLBACK* DLGPROC)(HWND, UINT, WPARAM, LPARAM);
To
typedef BOOL (CALLBACK* DLGPROC)(HWND, UINT, WPARAM, LPARAM);
But the Application Exit with out showing the dialog box ,
BOOL CALLBACK DialogProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
.
.
.
return true;
}
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
hInst = hInstance;
return DialogBox(hInstance, MAKEINTRESOURCE(DLG_MAIN), NULL, DialogProc);
}
P.S:
the code work perfectly when building for Win32.
Thank you.

That is a really bad idea. The windows API libraries have been tested extensively, and if you start changing them then you are likely to create far more problems than you will solve. The include file clearly shows you the format of your DLGPROC function, so it is up to you to create it to match that function definition; it returns an INT_PTR not a BOOL. You can also add a cast in your DialogBox() call to help the compiler along.
One of these days I'm going to think of a really clever signature.

The WinMain Function return.
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
hInst = hInstance;
return DialogBox(hInstance, MAKEINTRESOURCE(DLG_MAIN), NULL, DialogProc);
}

As I explained above, it is because your DialogProc() does not match the definition required by Windows. Check the documentation[^] and make sure that your declaration matches in every respect.
One of these days I'm going to think of a really clever signature.
|
|
|
|

You are right. But the conflict is :
DialogProc function Return INT_PTR while the WinMain which return the DialogProc "must return int."
I think I must find a way to convert from IntPtr to int safely ...
Thank you.
