You don't need to know the dimensions of the desktop in order to maximize your main window. Just post it a WM_SYSCOMMAND message with a wParam of SC_MAXIMIZE.

In Continuation With Mr Ravi,
You can also use Api ShowWindow(SW_MAXIMIZE);

I work in a project with 4 other people. We use Visual C++ DevStudio 6.0 and SourceSafe. I have a question about resource files.
If I edit a dialog in the resource editor, and check it in, MSDev changes the font line in the resource to say
FONT 8, "MS Sans Serif".
But if someone else changes it and checks it in, MSDev changes it to say
FONT 8, "MS Sans Serif", 0, 0, 0x1.
Does anyone know what this ", 0, 0, 0x1" thing is all about? Is it something I can turn off, because with a large number of dialogs in the same resource file, doing a diff is quite laborious.
Here is an example of a dialog, before and after:
<br />
IDD_OPTIONS_EDITOR DIALOGEX 0, 0, 307, 255<br />
STYLE DS_MODALFRAME | DS_CONTEXTHELP | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU<br />
EXSTYLE WS_EX_CONTEXTHELP | WS_EX_APPWINDOW<br />
CAPTION "Editor"<br />
FONT 8, "MS Sans Serif"<br />
BEGIN<br />
...<br />
<br />
IDD_OPTIONS_EDITOR DIALOGEX 0, 0, 307, 255<br />
STYLE DS_MODALFRAME | DS_CONTEXTHELP | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU<br />
EXSTYLE WS_EX_CONTEXTHELP | WS_EX_APPWINDOW<br />
CAPTION "Editor"<br />
FONT 8, "MS Sans Serif", 0, 0, 0x1<br />
BEGIN<br />
...<br />
Thanks

The format is:
FONT pointsize, typeface, weight, italic, charset

Thanks for that, but please tell me where you found this information so I can find out why it keeps changing.
I tested it some more and it looks like whenever I modify a dialog, MSDev seems to scan the entire .rc file and adds the ", 0, 0, 0x1" string on some dialogs, and removes the string from others. Regardless of whether I modified (or even opened) those dialogs.
Maybe I should write a small exe to rip out all the ", 0, 0, 0x1" strings, and run that before every checkin. Seems like overkill though...
HELP!
Cheers

Hi
how can i look for a file if it exists without using fopen
/\|-||\/|/\|)
|
|
|
|
|
here's a function that I put in one of my programs to make sure a folder existed, but you could also use it for a file.
BOOL FolderExists(CString strFolderName)
{
return GetFileAttributes(strFolderName) != INVALID_FILE_ATTRIBUTES;
}

Try this:
bool fileExists(LPCTSTR filepath)
{
return (_taccess(filepath, 00) == 0);
}
Hope that helps,

Another way:
<br />
WIN32_FIND_DATA wfd;<br />
<br />
HANDLE hFind = FindFirstFile(csFilePath, &wfd);<br />
if (hFind != INVALID_HANDLE_VALUE)
... <br />

Try one of the stat functions, e.g.
int stat (const char *path, struct _stat *buffer);
|

PathFileExists can help tooo

Hi
I have developed an application using the CBannerStatic class. For this I have used example given at : http://www.codeproject.com/staticctrl/bannerstatic2.asp
What I want is when I create EXE and run it, it should show the scrolling text. And I am statically adding the text at InitDialogue() function.
For this I am using a static control so display text. Now I want to show that static control into the size that user defines...Is there any way to dynamically change the size and position of the static control ?
Also I want to write a function such that if some one presses "ESC" key it will terminate the application. For this I have used ON_WM_CHAR, ON_WM_KEYDOWN but it's not working according to that any idea why it happens ?
Your kind help will be much important for me....

Sure, just use MoveWindow() or SetWindowPos().

Hi,
I have a Dialog based MFC app that is opening a modeless dialog. When I try
to minimize this window it minimizes to a small window just above the Start
button. Is there a simple way to make it minimize so that it appears in the
taskbar instead?
TIA,
Bob

How to get the size of the margin?
How to ignore the margin, i mean, make my print CDC full scaled to the paper. In other way, which function in MFC printing is to set the printing CDC size.
Thanks!

When I use the API in a DLL project, I got an error:
HANDLE hPrinter = NULL;<br />
PDEVMODE pDevMode = NULL;<br />
char szPrinter = {"HP LaserJet 9050 PCL 6"};<br />
<br />
BOOL bOpen = ::OpenPrinter(szPrinter, &hPrinter, NULL);<br />
if (!bOpen || hPrinter == NULL) return;<br />
<br />
long nSize = ::DocumentProperties(NULL, hPrinter, szPrinter, NULL, NULL, 0);
DWORD dwErr = GetLastError();<br />
if (nSize < 0)<br />
{<br />
::ClosePrinter(hPrinter);<br />
return;<br />
}<br />
<br />
pDevMode = (PDEVMODE)new char[nSize];<br />
if (pBuffer == NULL)<br />
{<br />
::ClosePrinter(hPrinter);<br />
return;<br />
}<br />
<br />
memset(pBuffer, 0, LENGTH_DEVMODE);<br />
long nReturn = ::DocumentProperties(NULL, hPrinter, szPrinter, pDevMode, NULL, DM_OUT_BUFFER);<br />
::ClosePrinter(hPrinter);<br />
if (nReturn < 0)
return;
1.On Windows XP system:
if nSize = 6132, the last error will be 0, and print will succeed.
if nSize = -1, the last error will be 1114, and print will fail.
After "DocumentProperties()", the last error maybe 0 and sometimes maybe 1114. 0 means success while 1114 means "A dynamic link library (DLL) initialization routine failed".
2.On Windows 2000 professional I never got the error.
How can I avoid to fail to print?

You should be calling GetLastError() to find out why.

Yes, I have done so.

What can I do?

hiho@ll
i'm using OnLButtonUp to get the coordinates of a mouseclick
the problem:
OnLButtonUp from MSDN: Specifies the x- and y-coordinate of the cursor. These coordinates are always relative to the upper-left corner of the window
so i thought using GetWindowRect and just adding the values point.x+=rect.left AND point.y+=rect.top will convert the relative coordinates to absolute
the problem is
for example if my window is in the middle of the screen and i click on the top of the screen (the absolute y position should be between 0 or 10)
i get an relative point.y coordinate -22!!!!
which means i clicked 22 pixel above my window? but i clicked a few hundred pixels above my window!
so how can i convert the relative coordinates to absolute?

I think you need to be using ClientToScreen. For example:
CPoint ptScreen = point;<br />
ClientToScreen (&ptScreen);<br />
Hope that helps, 'bod.
