Re: How to remove the Frame for SDI Application

17-Aug-06 1:03

You need to remove WS_OVERLAPPEDWINDOW style from windows style you are using
Make your CMainFrame::OnCreate function look like this

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
	return -1;
    ModifyStyle(WS_OVERLAPPEDWINDOW,0);
}

How to Get The Size of MDI Min Window

17-Aug-06 3:37

you need to override OnPaint if window is CMainFrame.For controls you need to make them owner drawn, and handle its appearance in OnDrawItem.

Printing a screen image (StretchBlt error)

you can't get it there. Window no longer exists at that point.

Re: Printing a screen image

17-Aug-06 0:26

I am writing a graphic design tool. I am using a device context to produce the image on screen. Now I want to be able to print the image to the printer. What I am doing so far is:

Create the screen device context : CDC *m_pDC = CreateDC ();
Do all kinds of weird and wonderful things to produce the image (all of this works, since I do get the image I want on screen)
When the user presses the Print option from the menu, I use the CPrintDialog class to select the printer, and subsequently I get a HDC by “CPrintDialog Print.CreatePrinterDC ();”
Then I calculate the size on paper by the following piece of code:

POINT point;
POINT start;

point.x = GetDeviceCaps (hDC, PHYSICALWIDTH);
start.x = GetDeviceCaps (hDC, PHYSICALOFFSETX);
point.x -= (start.x*2);
point.y = GetDeviceCaps (hDC, PHYSICALHEIGHT);
start.y = GetDeviceCaps (hDC, PHYSICALOFFSETY);
point.y -= (start.y*2);
DPtoLP (hDC, &point, 1);
DPtoLP (hDC, &start, 1);

I already have a POINT named “Source”, that holds the size of the screen DC.
Then I call:

if (!StretchBlt (hDC, start.x, start.y, point.x, point.y, m_pDC->GetSafeHwnd (), 0, 0, Source.x, Source.y, SRCCOPY))

And this is where all goes wrong! This fails, and the error message (as obtained by FormatMessage and GetLastError) says: “The parameter is incorrect”

As far as I can see, the size on paper is correct, since I also write a (test) rectangle with these positions: Rectangle (hDC, start.x, start.y, point.x, point.y); and this produces a rectangle on paper with the size and position as I would expect.

Can anyone help me out here.

Sarath,

Thanks for the tip. I checked the link, but it does not solve my problem, since it does not refer to sending the captured image to the printer. I do have a device context with a valid image. However, when I try to copy this image into a printer device context (using StretchBlt), I get an error message.

Before using stretchblt, i think you need to set SetStretchBltMode

printing to DC is not a big deal. it's same as using CDC

some devices cannot handle large bitmaps (see GetDeviceCaps(...RASTERCAPS), so you have to do your output in bands. some devices cannot do StretchBlt or StretchDIBits (again, see GetDeviceCaps)

6th parameter of API is HDC,whats is m_pDC->GetSafeHwnd ()?
I guess you are passing incorrect type of parameter. It should HDC(source).

Sorry, this is a typing error, I of course used GetSafeHdc () and not GetSafeHwnd ().
Meanwhile however, I think I found the solution. Since I am copying bitmaps between diferrent devices, I cannot directly BitBlt or StretchBlt between them. I am now using GetDIBits to get the device independant bits out of the screen's device context and then use StretchDIBits to move them into the printer's device context. This does require a lot of programming, but it does result in the required image on paper.

Thanks to you all for your efforts!

edit boxes and files

Hi! i want to write a '.txt' file getting data from a 'multiline edit box'. when i want to go to the next line in an edit box do i press ctrl+enter key? when i use this it gives an extra space character (" ") which spoils the format in the text file i am writing in.
i have also used 'endl;' in the instruction for writing to a file.

outfile << testdata << endl;

if i dont give endl; it gives me two line spaces in between each line in the text file, which again ruins the required file format. does anyone know what i can do to overcome this problem?
thanks!

searching the folder in a file

17-Aug-06 0:29

Hi,

You need to create the editbox with the "Want return" style. This can either be done from the dialog design (if your application is dialog based) by selecting the "Want return" option on the "Styles" tab. Otherwise, you need to specify the "ES_WANTRETURN" style when creating the editbox.

Success,
William

I used that but it shows error as

Why it occurs like this..
