Thanks for your kind concern but it isn't very helpful.
Actually i am looking where would OS store the changed settings for "control panel>ease of access center>optimize visual display>make the focus rectangle thicker". I have gone through registry but could not find it Frown | :(

Thanks again

How to retrofit C++ app to support B/S?

Hi everyone,

Right now, I'm working at a project that change it to support B/S mode. That is, user can do something by WebBrowser to invoke some functionality of C++ app, and I don' wanna make too complicated. The original C++ app don't support B/S, Is there any thirtd-party library to do that?Anyone tell me how to do that in more earier way?

If using SOCKET, I think that need to make a parser to analysizing middle-protocol, but this progress will spend much more time and quite complicated.

Any suggestion?

Thanks.

Unable to Load Image Other than .bmp by LoadImage Function? [modified]

Re: Unable to Load Image Other than .bmp by LoadImage Function?

28-Dec-08 18:09

HI all,

i m using LoadImage function to load image for printing.

i u using this.

CDC* pDC;
CPrintInfo* pInfo;
Cstring file_name;
CBitmap bitmap;
		  int maxw = pDC->GetDeviceCaps(HORZRES);
		  int maxh = pDC->GetDeviceCaps(VERTRES); 
		  pInfo->m_rectDraw.SetRect(0, 0, maxw, maxh); 

		  // LoadImage does the trick here, it creates a DIB section
		  // You can also use a resource here
		  // by using MAKEINTRESOURCE() ... etc. 
		  if(!bitmap.Attach(::LoadImage(
		  ::GetModuleHandle(NULL), file_name, IMAGE_BITMAP, 0, 0, 
		  LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE))) 
		  {
			AfxMessageBox(_T("Error loading bitmap!")); 
			return;
		  } 
		  BITMAP bm;
		  bitmap.GetBitmap(&bm);
		  int w = bm.bmWidth; 
		  int h = bm.bmHeight; 
		  // create memory device context
		  CDC memDC; 
		  memDC.CreateCompatibleDC(pDC);
		  CBitmap *pBmp = memDC.SelectObject(&bitmap);
		  memDC.SetMapMode(pDC->GetMapMode());
		  pDC->SetStretchBltMode(HALFTONE);
		  // now stretchblt to maximum width on page
		  pDC->StretchBlt(0, 0, maxw, maxh, &memDC, 0, 0, w, h, SRCCOPY); 
		  // clean up
		  memDC.SelectObject(pBmp);

its not able to load image.Please tell me how can i do this.

thanks in advance.

If you like easy work you can use of CImage class instead this code CImage works with Bmp,Jpg,png,gif,tiff and it has (StretchBlt,GetHeight,GetWidth,...) and other functions that you need to them.

Load is easy like this:
#include atlImage.h

CImage m;
m.Load(_T("c:\\1.jpg"));

You have this line on your code:

if(!bitmap.Attach(::LoadImage(
::GetModuleHandle(NULL), filename, IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE))) {
AfxMessageBox(_T("Error loading bitmap!")); return;
}

change to it:
CImage m;
m.Load(_T("c:\\1.jpg"));
....
....
....
if(!bitmap.Attach(m_.Detach()))
{
AfxMessageBox(_T("Error loading bitmap!")); return;
}

You can refer to Print Bitmaps without Doc/View Framework[^] for calculate image on the paper. Wink | ;)

my application crashes while I push_back a value of type POSITION.
I checked the call stack. The parameter to the insert function(push_back calls insert) was something else other than POSITION type.
How?

What could be the problem?
Please help!!

You need to google first, if you have "It's urgent please" mentioned in your question.

This code is used for holding the text selection made by the user.
CCursorPos is used for holding the cursor position.

	}

	CCursorPos& operator=(const CCursorPos& pos)
	{
		ASSERT(pos.isValid());
		setCursor(pos.getItem(),pos.getTextPoint());
		return *this;
	}

	BOOL operator==(const CCursorPos& pos) const
	{
		ASSERT(isValid());
		ASSERT(pos.isValid());

		return (getItem() == pos.getItem() && 
			getTextPoint() == pos.getTextPoint());
	}

	BOOL operator!=(const CCursorPos& pos) const
	{
		return !(*this == pos);
	}

	{
		ASSERT(isValid());

	{
		m_textPos = ptText;

	}

	CPoint m_textPos;		// in view coordinates
	POSITION m_posItem;

I replaced vector with CArray. But caused a crash after OnMouseMove() function was fully executed.

I see exactly the same problem in my code.

This problem occurred when I migrated to visual studio 2008 and attempted to execute the code using a release build.
The same code does not crash in debug build in VS 2008.

Has anyone been able to figure out the cause of the problem?

Thanks

Good day,

Were you able to fix your problem ? I'm having the same kind of problem when porting to VS2008.

Thanks.

I had the same problem when porting from VS2005 to VS2008.

I avoided it using dynamic allocation something like this:

std::vector *v;
v = new ???;

v->push_back(***)

This works in both debug and release mode Smile | :)
