What does __RPC_FAR do?
typedef /* [unique] */ IDispatch __RPC_FAR *LPDISPATCH;
What does this signify?
Thanks for helping!

16 bit environments used to have near and far pointers, and __RPC_FAR used to indicate a far pointer. It is provided for compatibility reasons, it is defined as nothing.

1. place the following string somewhere in your "stdafx.h" file:
#include <afxpriv.h>
2. override DoModal() function in your dialog class:
int CSampleDialog::DoModal()
{
CDialogTemplate dlt;
int nResult;
// load dialog template
if (!dlt.Load(MAKEINTRESOURCE(CSampleDialog::IDD))) return -1;
// set your own font, for example "Arial", 10 pts.
dlt.SetFont("Arial", 10);
// get pointer to the modified dialog template
LPSTR pdata = (LPSTR)GlobalLock(dlt.m_hTemplate);
// let MFC know that you are using your own template
m_lpszTemplateName = NULL;
InitModalIndirect(pdata);
// display dialog box
nResult = CDialog::DoModal();
// unlock memory object
GlobalUnlock(dlt.m_hTemplate);
return nResult;
}
It may be reasonable to choose a font for your dialog box according to user-specified schemes (those in Control Panel / Display / Appearance). Unfortunately I was unable to find any simple ways to get font settings for the dialog boxes. A possible alternative is to use font settings for icon titles and some related controls (like tree and list controls), that can be retrieved by SystemParametersInfo() function. Here is a simple procedure that returns the face name and the size in points for this font:
void GetSystemIconFont(CString& strFontName,int& nPointSize)
{
LOGFONT lf;
// get LOGFONT structure for the icon font
SystemParametersInfo(SPI_GETICONTITLELOGFONT,sizeof(LOGFONT),&lf,0);
// getting number of pixels per logical inch
// along the display height
COLOR="#990000">
HDC hDC = ::GetDC(NULL);
int nLPixY = GetDeviceCaps(hDC, LOGPIXELSY);
::ReleaseDC(NULL,hDC);
// copy font parameters
nPointSize = -MulDiv(lf.lfHeight,72,nLPixY);
strFontName = lf.lfFaceName;
}

Thanks ashok..it works.
Should i have to overide the Create() function so that the font will change when dialog is created as Modless?
nave

|
|
|
|
Yes..
Override create for modeles dialog.
Try that and revert me back whether it works fine or not.
Thanks & Regards,
Ashok

Halo Naveen,
I think you have not updated your dialog data after setting the font. After you finish setting the font in dialog, do UpdateData(0); If the problem is something else, I could give you a small sample code snippet on how to set a font. Please let me know of anything.

You have an idea and me too. We exchange those and We have two ideas each.

You can use a combination of LoadImage and StretchBlt.

And
CBitmap and StretchDIBits

I think this way is good
#include AtlImage.h
CImage m_Image;
m_Image.Load("c:\\picture.bmp");
//m_Image.BitBlt(GetDC()->m_hDC,CRect(0,0,800,600),CPoint(0,0));
m_Image.StretchBlt(GetDC()->m_hDC,CRect(0,0,200,200),CRect(0,0,800,600));

Hi ewighell,
There are some steps of doing this:
[1] Load the bmp in mem. Your can use CBitmap::Load to do this. the CBitmap class can give you a handle (HBITMAP) to this bitmap.
[2] Create a dc by using CDC::CreateCompatibleDC; select the bmp handle into this dc (CDC::SelectObject).
[3] Override the dialog's OnPaint function. use CDC::Bitblt or CDC::StretchBlt to render the bmp on to dialog surface.
Regards,
Chris
