Here is what I've coded for the task
case WM_MOVING:
{
LPRECT lprc = (LPRECT)lParam;
RECT WD;
GetWindowRect(hwndDlg,&WD);
WD.right -= WD.left;
WD.bottom -= WD.top;
RECT VDR;
SystemParametersInfo(SPI_GETWORKAREA,0,&VDR,0);
if(lprc->left <= VDR.left + 5 &&
lprc->left >= VDR.left - 5)
{
lprc->left = VDR.left;
lprc->right = lprc->left + WD.right;
}
if(lprc->top <= VDR.top + 5 &&
lprc->top >= VDR.top - 5)
{
lprc->top = VDR.top;
lprc->bottom = lprc->top + WD.bottom;
}
if(lprc->right >= VDR.right - 5 &&
lprc->right <= VDR.right + 5)
{
lprc->right = VDR.right;
lprc->left = lprc->right - WD.right;
}
if(lprc->bottom >= VDR.bottom - 5 &&
lprc->bottom <= VDR.bottom + 5)
{
lprc->bottom = VDR.bottom;
lprc->top = lprc->bottom - WD.bottom;
}
int HalfHeight = ((VDR.bottom - VDR.top) / 2) - (WD.bottom / 2);
int HalfWidth = ((VDR.right - VDR.left) / 2) - (WD.right / 2 );
if ((lprc->top >= HalfHeight - 5 && lprc->top <= HalfHeight) ||
(lprc->top <= HalfHeight + 5 && lprc->top >= HalfHeight))
{
lprc->top = HalfHeight;
lprc->bottom = lprc->top + WD.bottom;
}
if ((lprc->left >= HalfWidth - 5 && lprc->left <= HalfWidth) ||
(lprc->left <= HalfWidth + 5 && lprc->left >= HalfWidth))
{
lprc->left = HalfWidth;
lprc->right = lprc->left + WD.right;
}
return TRUE;
} break;
The only problem is after it's been snapped, when you move the mouse slowly away from the edge the window will stay put! Why does it do that?
I want it to mimic DVD Decrypter
Thank you.

The problem is that if the mouse moves slowly, you'll put it back where it was so that the user keeps having to drag it from the same spot. If they don't move enough, you'll keep snapping it back to where it was.
I think the easiest way (and I'm happy for someone to correct this) is to keep track of where the window and mouse cursor were when the operation was initiated (handle the WM_ENTERSIZEMOVE message) and calculate the full window position each time, rather than using the rectangle that was provided to you in the WM_MOVING message. Something like this:
In WM_ENTERSIZEMOVE:
- Get the window rectangle (GetWindowRect()) - I'll call it oldWindowPos
- Get the mouse cursor position (GetMessagePos()) - I'll call it oldCursorPos
In WM_MOVING:
- Get the current cursor position (GetMessagePos()) - I'll call it newCursorPos
- newWindowPos.left = newCursorPos.x + (oldWindowPos.left - oldCursorPos.x)
- newWindowPos.right = newCursorPos.x + (oldWindowPos.right - oldCursorPos.x)
- newWindowPos.top = newCursorPos.y + (oldWindowPos.top - oldCursorPos.y)
- newWindowPos.bottom = newCursorPos.y + (oldWindowPos.bottom - oldCursorPos.y)
[edit]Forgot to mention that after this, you'd snap the window position  [/edit]
Something like that, anyway

The office documents are OLE Compound Documents. You'll need to use the IPropertyStorage interface.
If you search for IPropertyStorage on Google and MSDN, you should find some examples.

Hi, sorry if this is in the wrong forum.
Im working on a project in C++ using the GDI; with WinMain and all that.
For one bit of it, im using TextOut to display some text, but I also want to display an integer that will change. So TextOut will appear as follows:
<br />
int name;<br />
<br />
TextOut(hdc,x,y,"text",strlen("text");
"text" is technically an 'address of string to print'
How do I display the contents of name using TextOut?
Before using the stringstreams method is suggested, ive already tried that and my compiler isnt having it, and changing my compiler isnt an option.

Use sprintf() to write the integer to a string, or CString::Format() if you're using MFC.

Look Like you are using Win 32 api based Project.
Here is the way to display the content of name variable
int nName=4;
<font color=#00ff00>
char szBuffer[20];
<font color=#00ff00>
sprintf(szBuffer,"%d",nName);
<font color=#00ff00>
TextOut(hdc,x,y,szBuffer,strlen(szBuffer));
or in place of sprintf you can use itoa() too (which convert interger to string)

Is there is any way to hide the DOS window that
shows when system command is executed.
system("Dir/ar>File.txt");
lists the readonly files to the file.txt.
Is it possible to use ShellExecute ?.if so what is the syntax?.I tried using cmd.exe with shellexecute but
seems that cmd.exe doesnt takes parameter.

Why not use FindFirstFile() and FindNextFile() instead of the antiquated system() call? You'll be much better off.

I have a proyect based on Chatsrv/chatter samples on Visual C++ 6.0. My surprise comes from the fact that the same proyect compiled on Visual C++.NET fails when receiving data for a short time. That is, for some time, I get the data through the socket but suddenly and with no exception catched, I give up receiving data  . Just in case it can turn out to be a clue, this communication is unidirectional, that is, I get the data from a monitor connection to a certain port.

If your 'set' is too fuzzy, shave 'em. Just try not to hurt yourself.
If that's not what you mean, try to explain yourself a little better.

Haven't you ever heard of fuzzy set theory?

type the word fuzzy into the search box at the top of the page. There are quite a few fuzzy logic/set articles on this site.

Is there a conveinient way to give an MFC ActiveX control a dual interface?
(Don't ask, COM+MFC makes me shudder enough already, but I need to wrap an MFC control)
TN65 describes a way, but basically everything has to be done twice.

Hi all,
I am capturing an image through a camera. The camera returns a pointer to a two dimensional array of pixels. How can I go about displaying these pixels into MFC? (Just like a webcam or a camera with an LCD does)
I have read tutorials on displaying .bmp using CBitmap ... However, will MFC understands the raw image file (no header, each pixel has 8bit grayscale).
I appreciate all of your help.
Thanks,
Beou
