Take care with that kind of I/O. You could easily fubar a filesystem that way...

In addition to the response from DavidCrow, you must read a number of full sectors in the ReadFile function. Else, ReadFile will fail on you.
A HD sector is normally 512 bytes. The actual sector size can be retrieved with a GetDriveGeometry call.

How to exchange boolean data of Edit Control of a dialog using DDX_....?
|
|
|
|
|
Just like you would any other type:
void AFXAPI DDX_Text( CDataExchange* pDX, int nIDC, int& value );

Thanks David
But if I try to exchange data between an IDC control and a structure member that is defined as boolean - The compiler poses an error.
What I'm doing right now is to store the value of this struct member (boolean)in an int, exchange the data with int and store this int back in struct member (boolean)- Any better way to do this - ?

You can always write your own custom DDX_ routine. They are not sacrosanct, after all.
Just use the one that does ints as a template and copy the code to your program.
Then modify it to accept the BOOL and do necessary conversions.
Any sufficiently gross incompetence is nearly indistinguishable from malice.

Do u mean i use AfxGetMainWnd()
& then use PostMessage to handling that with
CMainFrame class?

You indicated that you wanted to "call CMainFrame's function from my CDocument class." AfxGetMainWnd() is used to get a pointer to the frame window object. With that, you can call whatever function you need.

But i can not access function that i declare in CMainFrame object!
for example i wrote CreatePane function in CMainFrame object.
i wanna call this function
from CMyDocument ! i use AfxGetMainWnd but m_pMainWnd can not access
CreatePane or CreatePane did not declare in FrameWnd object!
best Regards.

Why not?

Probably because you forgot to cast the return value from AfxGetMainWnd() .

this is my code :
void CNcontabile::OnChangeGestiuneadb()
{
CString strCourseID;
CWaitCursor wait; // Display a wait cursor
CDatabase_Bun *pBun;
pBun = new CDatabase_Bun;
// Set the filter
pBun->m_strFilter = "um = '" + strCourseID +"'";
if(pBun->Open());
return;
if (pBun->IsOpen())
{
while(!pBun->IsEOF())
{
m_gestiuneaDb.GetWindowText(strCourseID);
strCourseID.TrimLeft();
strCourseID.TrimRight();
m_gestiuneaDb.SetWindowText(strCourseID);
if(strCourseID == pBun->m_um )
{
m_dengestiuneDb.SetWindowText("GGGGGGG");
}
}
}
pBun->Close();
delete pBun;
}
is not working because i have a filter and is no match !
my second problem is how to trim the spaces ? (CEdit & the CDatabase spaces ) ????????????

Why it doesnt work and what filter?

Bravoone_2006 wrote: pBun->m_strFilter = "um = '" + strCourseID +"'";
Since strCourseID is empty, this'll never work.
Bravoone_2006 wrote: m_gestiuneaDb.GetWindowText(strCourseID);
strCourseID.TrimLeft();
strCourseID.TrimRight();
m_gestiuneaDb.SetWindowText(strCourseID);
Why are you calling these in a loop? Call them once outside of the loop.
Bravoone_2006 wrote: if(strCourseID == pBun->m_um )
I don't suppose you've bothered to set a breakpoint on this statement to see the different values of strCourseID (which we already know is empty) and pBun->m_um . That's the main reason why you can't see the problem.
Bravoone_2006 wrote: is not working because i have a filter and is no match !
Actually it is working. It's doing exactly what you told it to do - find records where pBun->m_um is equal to empty. Hint: no records match this criteria.

By assigning it a value.

I wrote a Rss reader,used the webbrowser control.
I think it would be nice if I can integrate google toolbar.
so I tried.
but never worked
can anybody give me a help?
Much thanks!

I do not think that you can - I believe that BHOs and similar ADD-ins are supported by the "framework" provided by Internet Explorer, not by the WebBrowser control proper.
This is actually one of the dangers of hosting the WebBrowser control. If you allow it to be used for general browsing by a user (allowing dropped links, not properly disable the context menu, handing the new window event, etc.), the user is browsing in a "less secure" environment than Internet Explorer offers, and this may lead to problems (like popup-mismanagement).
Peace!

I could get hold of a lot of tutorials on Codeproject to custom paint the List View Items but I want to draw a custom selection bar. Is there any way this can be achieved?

Hi all,
I'm trying to get a region containing the icon from the listview. I tried using "ListView_GetItemRect(hSysListView32Wnd, i, &rect, LVIR_ICONS)" on
SysListView32, but it returns a region that is too big (contains a
rectangular block surrounding the icon).
Thanks in advance.
Amar.
