Crashing is usually caused by bugs.

I know, I already told you that. WTF | :WTF:

Maybe... I don't know I'm just spit-balling here, if you want to debug you should run the debug build! D'Oh! | :doh:

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/[^]

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.

Hi i hv design the controls in a form view. i want to move all controls to the center alignment with a frame control.how to do these?

-- modified at 0:43 Thursday 18th May, 2006

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

-Sarath

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.

"Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late" John Nichol "Point Of Impact"

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));
}

thanx steve , i 'll try these

Hi All,
im resposting my problem.

im not getting the current scroll position in an ownerdrawn listbox.

could u pls u help me to solve this?

-Sarath

of course i test this function you test in another function Smile | :)

<br />
void CAnswer::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)<br />
{<br />
//	CScrollBar* pScrollBar2;<br />
	SCROLLINFO	m_Scroll;<br />
	GetScrollInfo(SB_VERT,&m_Scroll);<br />
	CListBox::OnVScroll(nSBCode, nPos, pScrollBar);<br />
}<br />

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

Hi,

How to check whether a directory is write protected(not ready-only attribute) or not. I tried using _taccess_s but its not working for directories(MSDN confirms it). Is there any way to check it.

Thanks.

Adios,

Use GetFileAttributes function

-Sarath

Hi,

GetFileAttribute doesnot retrieve the write-protection setting. Thats why I specifically mentioned "not read-only attribute" in my post.

Thanks.
