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

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);
}

Go the Project/Settings menu, then click on C/C++, select 'Precompiled Headers' from the category dropdown, and switch them off.

hello all,

here i am designing an SDI Doc/View application. Instead CView i had used the CFormView to display my dialog inthe view. As given in the MSDN, i had followed a procedure to change that dialog in the view dynamically. But the problem is that the newly displayed dialog is not responding for various events(WM_COMMAND,...).

How shall i make it to work properly.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
