The CS_SAVEBITS style that I mentioned in that last message is for saving the bitmap of the screen the window will obscure - not the window itself.
Still, it might be what you had heard mentioned.
Have you tried responding to WM_ERASEBKND with a BitBlt as well?

Cool idea, checking it just right now ...

Ok , placing the same code as in OnPaint to OnEraseBkgnd doesn't help.
I've read MSDN about cs_savebits :
----------------------------
CS_SAVEBITS :
Menus, dialog boxes, and combo list boxes have the CS_SAVEBITS style. When you use this style for a window, Windows saves a bitmap copy of the screen image that the window obscures. First, Windows asks the ...
----------------------------
Seems like it's exactly what I need , BUT it's written that dialog based applications ALREADY HAVE IT ( see above ) - correct me if i'm wrong.\
If not , how I apply it - dialog doesn't have PreCreateWindow like Window applictaion.

You would need to register a new window class to use CS_SAVEBITS, but again I don't think its what you want - it will only cause your window to save the bitmap of what it is on top of, which won't help you - only the window you're covering.
Blatant plug: I posted an article here that plays with blits and tries to outline the paint messages that need to be dealt with. Although it's a bit non-standard, it might give you some ideas.

Some thoughts:
- draw only in OnEraseBkgnd
- what are you drawing on, in the dialog? are there controls on it?
- why don't you use a child window to draw?

How can I make a edit box scrolling down and stay scrolled down as data is entered into it. Any Help will be greatly appreciated.

the next code will keep the vertical scroll bar down
when you add line.
int l_nMin, l_nMax;
m_YourCEditControl.GetScrollRange(SB_VERT, &l_nMin, &l_nMax);
m_YourCEditControl.SetScrollPos(SB_VERT, l_nMax, TRUE);

Is it possible to not have a main window as normall proscribed?
Basically I would like to use the Dialog builder within Visual Studio to build my "main window." I've tried CreateWindow and CreateDialog all to no avail as they all want parent windows. But unfortunately I want the parent window to be a dialog.
Can anyone help me out in this regard? I've read Petzold and have yet to find anything usefull.

Not entirely sure what you're after, but if you use a style of WS_POPUP you won't need a parent. In fact, specifying this style by itself is the way to get a very minimal window happening.

Make sure your dialog has the correct properties such as WS_OVERLAPPED. You will need to call RegisterClass before CreateDialog. You'll also need to add IsDialogMessage to your message loop.
dialog.rc:
DialogApp DIALOG DISCARDABLE 0, 0, 416, 229
STYLE WS_OVERLAPPED | WS_MINIMIZEBOX | WS_CAPTION
CLASS "DialogApp"
FONT 8, "Times New Roman"
BEGIN
PUSHBUTTON "Ok",IDOK,214,191,50,14
END
WinMain():
szAppName = "DialogApp"
WNDCLASS wndclass;
wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = DLGWINDOWEXTRA;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon (hInstance, szAppName);
wndclass.hCursor = LoadCursor (NULL, IDC_ARROW);
wndclass.hbrBackground = (HBRUSH) (COLOR_BTNFACE+1);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppName;
if (RegisterClass(&wndclass)==0)
{
return 0;
}
hwnd = CreateDialog( hInstance, szAppName, 0, NULL);
while (GetMessage(&msg, NULL, 0, 0))
{
if (!IsDialogMessage (hwnd, &msg))
{
TranslateMessage (&msg);
DispatchMessage (&msg);
}
}

Hi all,
I want to use of vector or list continer for adding structure to array, how can i do that ?
For example:
struct myLib
{
.
.
.
} NNN;
vector<<>myLib> vec1;
vec1.push_back(...);
Is it true ?

struct myLib
{
.
.
.
} NNN;
vector<<>myLib> vec1;
vec1.push_back(...);
This will work, but if you use pointers to structs then you need to do this to dereference an iterator
(*it)->mymember
If you don't use pointers then you'll need to provide operator = for your struct if it contains any non-simple types. Of course, if it contains large items like a bitmap, this will also slow things down a *lot*. Finally, if you put pointers in, you need to call delete on them as you pop them from your vector, or remove them from your list.

Hi and thanks for your reply ...
Now, i know for adding new impelement to array i can use of vector or list continer ...
And i know vector can add new impelement in the last array and can't add new implement in middle the array, but list can ...

Because a vector is an array, to put something in the middle you need to reallocate the whole memory block. The insert function allows you to do it, and if it's full of pointers then I guess it's not so bad. But the thing is if you want random insertion/deletion, you should go for a list. If however, the loss of speed for random access is a problem go map - it's a binary tree which gives a good compromise between fast random insertion and fast random access.

That's all there is to it. Just keep in mind that it's going to make a copy of the structure each time you call push_back. So depending on what you are storing in your structure it might be better to store a pointer to a structure.

Well...
I want to create my own application using the Apache server.
Actully, The main purpose is:

(the XML That will be sent to the user doesn't matter)
Basicly, I want to send an answer to the user.

Howdy,
I used to know how to do this, but I've completely forgotten what I used to know. Here's the problem.
I have an MFC MDI application. I open it up with a new document. I use the document a while and then press select "File->Save" (or just press the disk icon).
The file dialog appears, open to the current working directory.
I don't want it to open to the CWD, I want the file save dialog to open to a directory that I specify.
How?
thanks
Jim

You can do it like this:
CFileDialog dlg(...); // whatever initialization you want
dlg.m_ofn.lpstrInitialDir = _T("C:\\My Folder");
dlg.DoModal();

Thanks, but that doesn't apply here.
If you make a empty MDI app you'll see that it is the MFC framework that calls the FileDialog, not the application programmer.
So I need someway to tell the application framework what value I want to put into m_ofn.lpstrInitialDir before it calls the open/save file dialog.

NB On NT4 you have to use the english group name regardless of local settings - don't know if this is true for win2k. In any case, you should probably check different local settings...

Thanks for your answer but I don't know the word for administrator in all the different languages where the application will be deployed.
There has to be an easier way.
