Hi,
I would like to ask if someone can help me to resolve the following problem I am experiencing while writing graphical images from an AutoCAD drawing into device context (metafile in a vector format (EMF) ). My C++ code, running on Win32 platforms, is using GDI functionality to create a region, to set the clipping boundary, to draw the (bounding box) border lines and to draw vector duplicates of AutoCAD elements within that bounding box. The resulting EMF file loads into a graphics program (PaintShop Pro 8) for further processing and conversion to a raster image.
The resulting vector images of the elements overlap "dead on" the test images (TIFF) created from screen shots but the viewing window (bounding box) changes its preset size to a smaller one. (Using the "canvas" function, I can resize the windows to its original size without loss of any data or precision.) So far, I could not find where the problem lies that the EMF generated image window is smaller than the preset clipping region.
Here is the skeleton of my code:
HRGN clipReg; // output region
int width; // width of output
int height; // height of output
HDC hdcEMF; // metafile data
HENHMETAFILE hemf; // enhanced metafile
clipReg = CreateRectRgn( 0, 0, width, height ); // int width = 2000, int height = 1500
int ires = SelectClipRgn( hdcEMF, clipReg); // to clip the vectors drawn within the 2000/1500 bounding box
//draw elements
ires = outBoundRect(); // border lines (rectangular bounding box 0/2000/1500)
ires = drawOutput();
// close EMF
SelectObject(hdcEMF, m_oldPen);
SelectObject(hdcEMF, m_oldBrush);
hemf = CloseEnhMetaFile (hdcEMF);
When I open the resulting EMF file, the PhotoShop reports a window size (canvass) of 1924 / 1443 instead of the (to be expected) 2000 by 1500? Can anynone out there help me to resolve this?
Thanks a lot,
Tomas

Hello All,
Is there a way to configure Visual Studio to use GCC or other compilers to generate native programs for devices with ARM9 processors. Anything is welcome, application wizard, project sample, add-in or a paper fragment containing the secrets of the universe. 
Thanks in advance

Hello, im having a problem creating a dialog from another dialog box, as of now, i create, initilize, and display the new page using:
void CDisplayPage::LoadPattern()<br />
{<br />
if( m_LoadPattern->GetSafeHwnd() == 0 )<br />
m_LoadPattern->Create();<br />
<br />
m_LoadPattern->OnInitDialog();<br />
m_LoadPattern->ShowWindow(SW_SHOW);<br />
}
where m_LoadPattern is an instance of the dialog i want to display. For the most part this works, it seems to create and paste the dialog, but when i got to use the box, it seems like its just a background imagine, and things from the calling dialog then pop up, in other words, it seems to be painted, but it can't be the active window for some reason... I can post more code, but hoping its a simplier problem than that. Thanks.

never call OnInitDialog() yourself ! it is called automatically by the MFC framework !
moreover, what about doing simply this :
CMyDialogType dlg;
dlg.DoModal();

well, if he wants a modeless dialog, he will do a Create and a ShowWindow.

Yes very useful indeed. I did find the problem though, it had to do with the style parameters in the resource file, im not sure which one was messing it up, cause i just used copied the same param's from another dialog that was working.

I am almost sure that your dialog's Border was not set to Dialog Frame in Properties Dialog.

I'm pretty sure it was the DS_MODALFRAME option... It looks like the same thing your talking about, without looking at what this option does.

Could some one help me with dynamically creating a combo box at a particular position. Currently I have a text Box, I need to replace this text box with a combo Box.
Any help will be greatly appreciated.

you could create both with the resource editor, and at initialization time of the program, hide on of the two using CWnd::ShowWindow(SW_HIDE).
d'you follow me ?

I have done this (drop-down list boxes) in C, SDK-level stuff. Is this any use, or are you looking for this new-fangled C++, MFC, etc code?

Hey,
I use a CRichEditCtrl to display RTF-text on screen and later to a printer. My code works pretty good for "printer - output" but on screen output my text is moved (ca. 2cm).
Can you help me solving this problem?

Hello !
I need to 'compute' a random __int64 value that must be included between two values (both are __int64 too).
Any idea how I can manage that ? I don't think it exists something else than rand_s() function that will 'return' a random unsigned int.
I'm trying to find how I can manage to do that by simply using this function several times but it's the end of the day and my brain is too slow yet 
Any idea ?

__int64 i64 = (__int64)rand() * (__int64)rand();

Hi !
Thanks for your response but unfortunately it doesn't help a lot: first, the range is not respected (the number must be between a min and a max value). And second, rand returns an unsigned value (from 0 to 32768).

i thought i knew that, but for some reason i assumed "int" means "32 bits worth of data", in the MSDN - like maybe MS had a better version of rand. oh well.
but, you can just call rand() multiple times and bit-shift the bits into a pair of 32-bit values, which you can then assign to your i64. there's nothing else in the standard C/C++ RTL to give you more than 16 bits of random data at a time.
this isn't cryptologically secure, of course. but if you need that, the obvious place to look is in a crypto library (crypto++, for example)

Yes, in VC 2005 you have rand_s which will compute a random unsigned value (from 0 to UINT_MAX).

Yes, no problem for that I thought already about that but then I have the problem of the ranges  . You will certainly understand that my head is buring now  .
But nowaday, thanks for the help. I will sleep a night on it and tomorow, everything will be clear

See here. The period, M, can be changed to your liking. You might also have to change A to get full-period generator.

I often have to change my stdafx.h pch file for stuff like WINVER to have access to certain things in the win api. Of course I could just make a copy of this file and use that one as my starting point. But is there a way that I can change it so that when VS (.net 2003) creates it, it always has the #defines the way that I want them?

Go to the following directory:
<Visual Studio Install Path>\Vc7
Do a search for files named stdafx.h.
You can now see all the stdafx.h files and modify the one for the project that you use.

1) Is there a way to programatically check/uncheck the checbox in this control?
2) Is there a way to tell when the checkbox has been clicked on?
