Hi,
I'm just guessing. Have you tried WM_MDIDESTROY instead of WM_DESTROY?

Hi,
I have one application that every time that needs to draw calls a thread to do it ( it has a very sllow drawing proccess some graphical sh*ts...).
The problem that I have is..., How can I know what is the invalidated portion ? ( now when I call the thread it repaints all and it's very slow, I would like to know if it is only a portion of a window to redraw...), Is anyway to know this ?
Thanks, Bye !

Hi, where I can find a GUI toolkit to build graphical GUI like Winamp (non-rectangular dialog, bitmap)
Thanks

Hi,
It is pretty easy to display a non-rectangular window by using SetWindowRgn() function. The painting of the background of any window using a bitmap is a bit more difficult as long as you would probably need to work with DIBs (Device Independent Bimap) but shouldn't be that big of a deal. As for the GUI toolkit you might take look at the Dundas (www.dundas.com) Ultimate Toolbox (it has classes that handle irregular shaped windows and background painting). or you might try to find some free classes on this site that will help you to solve your problem

Andrei Zenkovitch

There are a couple a shareware programs designed just for this. I believe nullsoft, the makers of winamp, used one of them for their product. One product is called ActiveSkin and it looks like the one of choice. The second product, and the one I believe nullsoft used escapes me right now. I remember doing a search for skins and coming across a site that claimed to make the product of choice for nullsoft. I will look into it and get back to you. However once again, the ActiveSkin product was newer, more impressive, and less expensive. The product of choice.

Q: how to keep my application from being listed in the task manager and/or the task bar?
I think this is a relatively common need, but I can't find where it's documented.
Secondly, how can I force a child process of mine (with its own top level window) to be hidden from the task manager? I am not able to alter source-code for this process. Am I up a creek here?
Thanks in advance!

I have a tab control that contains child dialogs. I have been able to add the dialogs OK, and they show up, but when I press Enter or Escape (both mapped to default buttons on the dialog), all of my controls disappear. I have heard that I may have to override EndDialog, since this is probably being called, but I was wondering if anyone else has a better solution. I don't want to use Property Sheets, and I know this can be done with dialogs. Any help would be greatly appreciated.

look this code:
BOOL CYouChildDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
BOOL bHandledMsg = FALSE;
switch (pMsg->message)
{
case WM_KEYDOWN:
{
switch (pMsg->wParam)
{
// hitting escape while searching for password edits
// should only stop the search for password edits and
// not kill app
case VK_ESCAPE:
bHandledMsg = TRUE;
break;
case VK_RETURN :
bHandledMsg = TRUE;
break;
default: break;
} // switch (pMsg->wParam)
}
break;
default: break;
} // switch (pMsg->message)
return (bHandledMsg ? TRUE : CDialog::PreTranslateMessage(pMsg));
}

I have implemented gradient filled text by using the CDC functions BeginPath(), EndPath() and SelectClipPath(). This works, but the characters are jagged. Any ideas on how to achieve antialised characters?

I Need help..
I am development a program that you can use to view big log-files, in size about 10MB.
I have to use MFC, but I prefer Win32 API.
In Win32, I already solved the problem.
I use memory-mapped files to store the file in virtual memory, but I want to read directly from the file..?? Now I read the file to a String and then mapping it. Then a use Pointer to show the text in a window and that is my second problem. I get the String in one single line (no return). In Win32, I used to send the String with a SendMessage to the hWnd window. The third problem is with scrolling windows. In Win32 I only create a child window with WS_VSCROLL | WS_HSCROLL and then no problem..........
I get mad about MFC you do not have it under control....
I think that more people have same problem as me.
I really need some code-examples how to manage memory-mapping, scrolling and text.
Thank you..

Hello all,
I have a strange problem relating to ISupportErrorInfo. I have a component implemented as a collection class. This class is created as an MTS component and I added the _NewEnum, Item and Count properties to it, so I can use it as a collection. This all goes well. But now I added the ISupportErrorInfo interface. When something doesn't go as I want I do
[ccode]
return Error( L"My Message", IID_IMyInterface, E_FAIL);
[/ccode]
so I can see the error in a VB client with the Err object. But strange thing is that this only works with late binding, not with early binding. So if I declare a variable with
[ccode]
Dim obj as OBject
[/ccode]
I can see the error with err.description, but when I declare it with
[ccode]
Dim Obj as MyInterface
[/ccode]
it doesn't work that way and the Err.description simply tells me that "method 'SomeMethod' of component 'MyInterface' fails"!!!!!
Anybody has a clue what I could have done wrong? I use NT ws4 sp6 and VS6 sp3
TIA
Henk

Hi!
I've tried to create a simple ATL object using VC6 wizard, which supports ISupportErrorInfo. Then I added the method, which returns an error the same way as you, and then I tried both ways of using the object in VB - no any problems!
You can follow my steps and try to create a simple object and then test it...

Alex Gorev,

Merry Christmas,
Hi, a I have a Dialog Based application. The default window class is #32770 (Dialog).
I have tried to handle the PreCreateWindow and CreateWindow virtual functions, but they are never called.
Do anybody know what is the problem?
Thank You

These functions never called in MFC-based dialog. If you will see at source, you can see these calls does not exists. That's because there are no reasons to do it. You can change your dialog styles in editor

Hi Alejandro,
Here's how to change the class name in a dialog-based MFC app. There are two things you have to do:
1) register the new class name in InitApplication;
and 2) use the same class name in your .rc dialog template. See below for an example taken from a working MFC app. Good luck!
In your CWinApp file:
BOOL CApp::InitApplication()
{
WNDCLASS wc;
wc.style = CS_DBLCLKS | CS_SAVEBITS | CS_BYTEALIGNWINDOW;
wc.lpfnWndProc = DefDlgProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = DLGWINDOWEXTRA;
wc.hInstance = AfxGetInstanceHandle();
wc.hIcon = LoadIcon(IDR_MAINFRAME);
wc.hCursor = ::LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)COLOR_WINDOW + 1;
wc.lpszMenuName = NULL;
wc.lpszClassName = "MyClass";
::RegisterClass(&wc);
return CWinApp::InitApplication();
}
In your .rc file:
IDD_MY_DIALOG DIALOGEX 0, 0, 292, 167
STYLE DS_MODALFRAME | WS_MINIMIZEBOX | WS_POPUP | WS_CAPTION | WS_SYSMENU
EXSTYLE WS_EX_ACCEPTFILES
CAPTION "My Excellent Dialog"
MENU IDR_MENU
CLASS "MyClass"
FONT 8, "MS Sans Serif", 0, 0, 0x1
BEGIN
CONTROL "", IDC_SHEET, "Static", SS_BLACKFRAME, 5,7,234,142
CONTROL "Go", IDC_PROCESS, "Button", BS_OWNERDRAW | WS_DISABLED |
WS_TABSTOP, 248,8,42,20
PUSHBUTTON " Use\nMRU File", IDC_USEMRUFILE, 248,32,42,20, BS_CENTER |
BS_MULTILINE | WS_DISABLED
PUSHBUTTON "Exit",IDC_EXIT,248,128,42,20
LTEXT "Ready", IDC_STATUSBAR, 5,153,284,12, SS_CENTERIMAGE
END
