Hi
I have image, that changes its position for every 1 sec.like a progress bar. Here I am drwing it using TransparentBlt() here the top position is -x. Now I am not able to erase the top -x portion. If I do InvalidateRect(), whole main window flickers. How can this be resolved?

Crashing is usually caused by bugs.

I know, I already told you that. 
Maybe... I don't know I'm just spit-balling here, if you want to debug you should run the debug build!

how to get information the about type of file ( if even the extension is unknown)
Any tool is there?
|
|

|

There are thousands of file formats out there. I know of no one tool that will decipher them. There is this however: http://www.wotsit.org/[^]
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hi
placing and fetching all the windows controls,active x controls and whenever i want to place these controls in different windows then how??
|
|
|
|
|
Do you mean that you want to produce the drag and drop effect for controls on the window?
Somethings seem HARD to do, until we know how to do them.

it seems u have to calculate the width of the window and control and accordingly place it using MoveWindow function.

no There is one api with which we can move all the controls in a single instance do anyone know these?

No there is not. You were given the correct answer before.

Here's some code to do it. Call "CenterChildren" with a HWND.
-------------------------------------------------------------
BOOL CALLBACK MeasureChildrenBoundsProc(HWND hwnd, LPARAM lParam)
{
RECT *pRectUnion = reinterpret_cast<RECT*>(lParam);
RECT RectControl;
GetWindowRect(hwnd, &RectControl);
HWND hParent = GetParent(hwnd);
MapWindowPoints(NULL, hParent, reinterpret_cast<LPPOINT>(&RectControl), 2);
UnionRect(pRectUnion, pRectUnion, &RectControl);
return TRUE;
}
BOOL CALLBACK OffsetChildrenProc(HWND hwnd, LPARAM lParam)
{
POINT *pPoint = reinterpret_cast<POINT*>(lParam);
RECT RectControl;
GetWindowRect(hwnd, &RectControl);
HWND hParent = GetParent(hwnd);
MapWindowPoints(NULL, hParent, reinterpret_cast<LPPOINT>(&RectControl), 2);
SetWindowPos(
hwnd,
NULL,
RectControl.left+pPoint->x,
RectControl.top+pPoint->y,
0,
0,
SWP_NOZORDER|SWP_NOSIZE
);
return TRUE;
}
void CenterChildren(HWND hWnd)
{
// Calculate the bounding box around our children.
RECT rc = {0};
EnumChildWindows(hWnd, &MeasureChildrenBoundsProc, reinterpret_cast<LPARAM>(&rc));
// Move the children.
RECT RectParent;
GetClientRect(hWnd, &RectParent);
int ParentWidth = RectParent.right-RectParent.left;
int ParentHeight = RectParent.bottom-RectParent.top;
int ChildrenWidth = rc.right-rc.left;
int ChildrenHeight = rc.bottom-rc.top;
POINT offset = {(ParentWidth-ChildrenWidth)/2-rc.left, (ParentHeight-ChildrenHeight)/2-rc.top};
EnumChildWindows(hWnd, &OffsetChildrenProc, reinterpret_cast<LPARAM>(&offset));
}

What function are you using to get the scroll position, GetTopIndex()?
