You aren't very clear, however you can call GetLastError() to see why. You may have passed an invalid HWND.

I am creating an application which uses a "modified MDI-style" interface (Multiple SDI Windows) as described on MSDN. I have only 1 main frame window, and then from there you can open other different types of frame windows. The problem is that for each new frame that is created (I create a new frame and then call
pFrame->LoadFrame(WS_OVERLAPPEDWINDOW,NULL)), it adds another item to the windows task bar! -- a behavior which i wish to avoid if possible. I find that if I pass in a pointer to the main window (LoadFrame(WS_OVERLAPPEDWINDOW, AfxGetMainWnd()) that it prevents this behavior, but causes an even bigger problem: any frame windows spawned this way are always on top of the main frame window and obstruct my viewing it even when its active! (even if i set its style to WS_CLIPCHILDREN and WS_EX_TOPMOST)
I wish to find a solution that gets around both of these problems and am recruiting anyones help who knows.
Thanks so much,
Ben

WS_EX_TOPMOST should place the window above the other, you might try calling SetWindowPos() or using Create() instead of LoadFrame().

Hello,
I use GDI+ with VC++.
But painting pictures speed is slow terribly.
"DashStyleSolid" is fast, but "DashStyleDot" is very slow.
It is very late besides "DashStyleSolid".
Time of big figure and a lot of figures is terrible.
Are there what or measures?
Thank you.

That's just how it is, it seems. I think that on Windows 9x/ME/NT it has to create a new Windows GDI bitmap each time it draws. You can improve performance by caching the bitmap.

Thank you for an answer.
I paint pictures in Bitmap of GDI.
And I forward the Bitmap to DC with BitBlt.
However, it becomes very late by "DashStyle".
Can there be a thing that it becomes late by "DashStyle"?
Thank you.

Hello,
I have a binary file format that I am trying to develop a reader class for. The "word" size is always 8 bytes for double, integer or character values. I have written something like this for a file that uses 4 byte words, which is easier because an int=float=char=4 bytes.
Somehow I have to take the 8 byte word and split it into two 4 byte words and then cast? them to integers or characters.
double value
fread(value, sizeof(double), 1, m_fp);
// now get rid of the 4 bytes I dont need
// ....
Dont know if this will work or not... Any suggestions?

Assuming that it is little-endian:
char buf[8];
fread( buf, 8, 1, m_fp );
int nMyInt = *reinterpret_cast<int*>( buf );
If it is big-endian:
char buf[8];
fread( buf, 8, 1, m_fp );
int nMyInt = ntohl( *reinterpret_cast<int*>( &buf[4] ) );

Hey, I have a IE toolbar named KControl.dll and have just come upon a little program on Microsoft.com that will register it so that it can be used on another computer. Here is a link to the article:
http://support.microsoft.com/search/preview.aspx?scid=kb;en-us;Q207132[^]
Right now the pszDllName is set to NULL. How can I make it so that it register's my DLL? I'm not quite sure what to add. Does the DLL have to be in the workspace? Any help would be greatly appreciated.
|
|
|
|

If you are doing this in your own code and already know the DLL's name, then you should only be interested in everyting below this line...
HINSTANCE hLib = LoadLibrary(pszDllName);
With pszDllName set to the DLL's path (including filename).

I'm still getting the same errors I got last time:
C:\WINDOWS\Desktop\Will's Folder\kazaatools\KControlInstall\Register.cpp(127) : error C2065: 'KControl' : undeclared identifier<br />
C:\WINDOWS\Desktop\Will's Folder\kazaatools\KControlInstall\Register.cpp(127) : error C2228: left of '.dll' must have class/struct/union type
I put HINSTANCE hLib = LoadLibrary(KControl.dll); (assuming they are in the same folder)
Do you know how to fix this? Thanks.

Anyone out there have a clue on resizing the non-client area of a window? I know of WM_NCCALCSIZE, but AFAIK that only controls where the client area is placed on top of the non-client area and doesn't actually change the non-client area's width.
So, say I have a window with a width of 25 for the client area and 29 for the non-client, how do I make the non-client area say 27 and keep the client area at 25? Any thoughts?
TIA,
Jeremy Falcon

Thanks for the speedy reply, but I'm talking about changing the non-client area in relation to the client area, not just the window's size. SetWindowPos() only affects the non-client area of a Window.

You know, I tried to find that out myself recently, but with no luck. The AdjustWindowRect function adjusts the window's size to achieve a certain client size, but it maintains the client/outer ratio. So...

You may want to try using SetWindowRgn() to force the client/non-client area to appear smaller than it actually it is. This is also a standard way of drawing non-rectangular windows.

Then you couldn't have a user-resizable window, and you would have to adjust for the invisible part when resizing the window.

You'd change the region in response to a WM_SIZE. You can fake the sizing boundary (the rectangle shown when the user resizes a window) by overriding WM_SIZING.
