hi alok,
thanks a lot for ur reply,
but eventually i figured out my problem was not related with opening or closing but what i am using is ASyncSockets which are by default NON blocking sockets as a results the connection closes automatically if there is no buffer recieved so i used CSocket class ie a Blocking Socket class as a result untill unless the Buffer is recieved the connection is alive.
thanks a lot again

I only have Visual Studio .NET 2002 installed.

The similar one is "Object Browser" (Ctrl - Alt - J) found in Visual Studio .NET 2002.

Sir,

I am integrating flash with VC++.

I am using Dialog Based App.

I inserted this Active X Control.

I wanted to show both this Control and Dialog Window in a maximized state.

I called ShowWindow(SW_MAXIMIZED) in OnInitDialog.

When I execute the App I get the main window in maximized but the control in that is not at all maximized.
Pls help.
Regards
Chintu

You'll have to move yourself the control at the size and position you want based on the client coordinates of the parent window.
Take a look at MoveWindow in the MSDN.

CImageList + CTreeCtrl problem

Hi all,

I have my class that Inherites from CTreeCtrl.
I override OnPain() and i draw the items myself.
next to each item i am trying to draw an image

i use the following code:

// creating the bitmap:
m_imageOptions.Create(IMAGE_DIMENTIONS,
		  IMAGE_DIMENTIONS,
		  ILC_COLOR24 | ILC_MASK,
		  MAX_OPTIONS_NUM,
		  0);

// drawing the bitmap OnPaint() override
hBmp = pDlgInf->GetBmp();
CBitmap bmp;
if (NULL != hBmp)
{
 bmp.Attach(hBmp);
 iImage = m_imageOptions.Add(&bmp,TRANSPARENT_CLR);
 bmp.Detach();
 ::DeleteObject(hBmp);
}				
		
CPoint pnt(rc.left + SPACE_WIDTH / 5,rcText.top);
m_imageOptions.Draw(pDC,iImage,pnt,ILD_TRANSPARENT);

// don't handle the OnEraseBkgrnd
BOOL CPrfTreeCtrl::OnEraseBkgnd(CDC* pDC) 
{
	return TRUE;
}

problem:
I manage to see the image next to the item, but if i drag my dialog (the tree
is placed over a dialog), outside of the screen boundaries and then drag it
back within the screen boundaries, the image is gone...other drawing of the tree (such as the items) are correct....

what am i doing wrong? can any1 help?

thanks in advanced

You can display an image as the list control background using the following code:

LVBKIMAGE image;
memset(&image, 0, sizeof(image));
image.ulFlags = LVBKIF_STYLE_NORMAL|LVBKIF_SOURCE_URL;
image.pszImage = szFileName;
image.xOffsetPercent = 50;
image.yOffsetPercent = 50;

SendMessage(m_hListView, LVM_SETBKIMAGE, 0, (LPARAM)&image);
SendMessage(m_hListView, LVM_SETTEXTBKCOLOR, 0, CLR_NONE);

Rotating bitmap around its center

21-Apr-04 21:57

Hi!
I'm trying to get a bitmap to rotate. I want the bitmap to rotate around its midpoint (or an abitrary point)
I first used the formula:

<br />
xNew = (x * cosTemp) - (y * sinTemp);<br />
yNew = (x * sinTemp) + (y * cosTemp);<br />

but this only rotated the bitmap around the upper-left corner, and therefore I changed to this:

<br />
xNew = ((x * cosTemp) - (y * sinTemp)) + xRotAxis;<br />
yNew = ((x * sinTemp) + (y * cosTemp)) + yRotAxis;<br />

now the image is rotating around the x-and yRotAxis, BUT at the upper-left corner of the surface and thus hiding 3/4:s of the picture!

How do I make it rotate around its center at the surfaces' center? Confused | :confused:

I've contacted Intel, and they said that MMX application notes were removed due to age. An older copy of the notes can still be found at a third party website at

Hi Thanks Maxwell.
But I am not using MFC. It is a simple C program.
Also do I need to include any header file to use CString.

Amar.

Forget about CString stuff, since it is of C++.

For C program, do this way:
//
#include <windows.h>

/* ..... */

/* in your function, for example. */
void FooBar()
{
int iNum = 12345;
char sText[12] = {0};
sprintf(sText, "%d", iNum);

/* Including windows.h is for MessageBox function call. */
MessageBox(NULL, sText, "MyMsg", MB_OK);
}
