If you're starting out without any idea about the file, no file extension for example, then you'd have to parse the headers on the front of the file using a parser/recognizer capable of distinguishing different formats. The detailed format information of the format used will then contain information like what is in the file, details of audio and video streams, encoding, compression, encryption, authorship etc. There is no single standard format for media files or their headers so you need to know what you're looking for. You occasionally come across files that are completely raw, i.e. no header at all and you can't use then unless you happen to know the exact format, eihter by the association of the file with a particular application or by its extension. Most files though will have a valid header and many header layouts will be publically available.

Nothing is exactly what it seems but everything with seems can be unpicked.

Remove toolbar button border in release mode

I have an MFC app which creates toolbar using sectoolbarmgr. We have written a wrapper over secframewnd which to be used as frame.

My problem is - the toolbar looks absolutely fine when seen in debug build. But in Release build, each toolbar button has an ugly green/blue colored border around it.

Is there any way to suppress this un-needed toolbar button border ?

Thanks

Of course I think you show that your answer is CListBox.;P

Well, because you mention columns, presumably you are dealing with a ListViewControl and not a ListBox, so try something like this:

TCHAR pszText[_MAX_PATH];<br />
LVITEM lvi = { 0 };<br />
lvi.mask = LVIF_TEXT;<br />
lvi.pszText = pszText;<br />
lvi.cchTextMax = _MAX_PATH;<br />
lvi.iItem = 0;  // put the row number here<br />
lvi.iSubItem = 0;  // put the column number here<br />
SendMessage(hwndList,LVM_GETITEM,(WPARAM)0,(LPARAM)(LPLVITEM)&lvi);

lvi.pszText may not be still pointing to pszText upon return.

Well yes I thought it was, but I also thought I had better state the obvious, just in case the other 3 were right.

If you are using MFC, you should have a CListBox member variable associated with the listbox control. Use its GetItem() method instead.

CScrollView shows an unneccesary vertical scrollbar

Hi,
I have a csplitterWnd based class with 2 view and one view contains cscrollview along with some other controls. My problem is when i set the scroll sizes of the scrollview i sometimes get an unnecessary vertical scroll bar. This scrollbar disappears as soon as i move the split. Remember the splitter view is not direct child of the csplitterwnd class. But i still tried to call the recalclayout of the csplitterwnd when ever i change the scrollsizes of the cscrollview. But the scrollbar is still there. Any suggestions please!

Take a look into ResizeToFit or try to SetScrollSizes with a lower value.

A dialog box will have a different frame. Better create new Window being child of the active one.

Diference between Modal and NonModal is if you are allowed to make another things while the dialog is active, but has nothing to do with your question.

do you mean something like this:

LONG WINAPI IsUserAdmin(void)
{
BOOL b;
SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
PSID AdministratorsGroup;

b = AllocateAndInitializeSid(
&NtAuthority,
2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0,
&AdministratorsGroup);

if(b) {
if (!CheckTokenMembership( NULL, AdministratorsGroup, &b)) {
b = FALSE;
}
FreeSid(AdministratorsGroup);
}

return(b);
}

LOL, it is not that difficult, you just need to spend a lot of time reading and experimenting.

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