<code>// coneverterDlg.cpp : implementation file

CString strttime= time.Format ("%Y%m%D%H%M%S");
cEdit2.SetWindowText (strttime+"\n");//;(str)
cEdit2.SetWindowText (strttime+"\n");
string line(str);
//line.c_str (),100);

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));
}

of course i test this function you test in another function
<br />
void CAnswer::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)<br />
{<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.

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.
Adios,

I have a program with some ini profile files. For dynamicly changing profile files when the app is running, i change the m_pszProfileName value which is a attribute of the App Class. But some problems bother me, the values are loaded correctly for each ini file when the app first running, while it does'nt work after i changed the m_pszProfileName value when the app run.
Can anybody help me?
Thanks.
<br />
void update()<br />
{<br />
....<br />
<br />
free((void*)m_pszRegistryKey);<br />
m_pszRegistryKey = NULL;<br />
free((void*)m_pszProfileName); <br />
m_pszProfileName =_tcsdup(szPath); <br />
....}<br />
...<br />
{<br />
AfxGetApp()->GetProfileString(......);<br />
}<br />
...<br />

You can check in sources what is wrong there (maybe it caches open file handle), but why don't you use GetPrivateProfilexxx functions directly?

 There is a statement in the description of the CArray in MSDN:
……
If you need a dump of individual elements in an array, you must set the depth of the CDumpContext object to 1 or greater.
………
What dose “the depth of the CDumpContext object” means? I can’t understand.

I see from msdn that the generic mapping of atof() is _tstof(), but I can't use it even after I include <stdlib.h> & <stdio.h>. So, which .h file should I include?
MSDN:
TCHAR.H routine _UNICODE & _MBCS not defined _MBCS defined _UNICODE defined
_tstof atof atof _wtof
