Have a look at www.flipcode.com, there are heaps of examples of how to solve these problems, and more with filepackers. I think the Code-Of-The-Day sample at the moment is a filepacker, but the archives have some good examples as well.
From what I can remember most of the suggestions are about unzipping to memory, using a secondary thread. The idea being that before you know you are going to need something, you send a request to the unpacker, which queues the request and saves the memory block which you can get later. If the memory hasn't loaded, then you have to wait.
Sorry about the bad explanation, but the people on the flipcode message boards have heaps more experience on this stuff.

Thanks! I've been looking at flipcode at their packer code, still trying to work it out.
(Any more suggestions still welcome.)

 How to add a default bitmap to the picture control?
Thanks

hi...
you can use like that;
CStatic my_Static=(CStatic*)GetDlgItem(IDC_STATIC...);
myStatic.SetBitmap( ::LoadBitmap(NULL, MAKEINTRESOURCE(.....)) );
Good Work....

Is there a way to create an MHT file from my program? It is my understanding that it is a multipart mime object, but I don't know how to create that either. Thanks for the help.

Hi, I have MFC application with splitter window that divides client area to two views, both are CListView-derived classes. Because I want to keep columns to have stable proportions all the time, I'm catching CMyListView::OnSize() and executing this code:
void CMyFileView::OnSize(UINT nType, int cx, int cy)
{
int my_cx = cx;
INT iWidth = 0;
RECT viewRect;
::ZeroMemory(&viewRect, sizeof(RECT));
GetClientRect(&viewRect);
INT iViewLen = viewRect.right - viewRect.left;
CMultiColumnSortListView::OnSize(nType, cx, cy);
// disable horizontal scroll bar
GetListCtrl().ShowScrollBar(SB_HORZ, FALSE);
INT iColWidth = 0;
if (cx != old_cx)
{
GetListCtrl().ShowWindow(SW_HIDE);
for (INT i = 0; i < (COLUMN_NUM - 1); i++)
{
iColWidth = viewRect.right * COLUMN_WIDTHS[i];
iWidth += iColWidth;
GetListCtrl().SetColumnWidth(i, (viewRect.right * COLUMN_WIDTHS[i]));
}
GetListCtrl().SetColumnWidth((COLUMN_NUM - 1), (iViewLen - iWidth));
GetListCtrl().ShowWindow(SW_SHOW);
}
}
old_cx = cx;
}
I call ShowWindow() in order to stop flickering, it helped. The problem is, calling ShowWindow() deselectes selected item (selected before with SetItemState()). I tried to call SetItemState() again after ShowWindow(SW_SHOW), but it doesn't work as expected, it highlights item, but it doesn't select and focus it 100% (it just draw grey rectangle aroung the item, but doesn't display dark blue rectangle which appears in normal case).
Does somebody know what to do to select and focus the item again successfully?
Thanks for any suggestion.

Hey everybody..
I'm writing code that will display a popup menu when a user clicks an item in a listview control. In order to have the popup display right underneath the mouse cursor, I need to know the x.y position of where the user clicked in the list.
I've searched the help, but turned up nothing, is there a GetMousePos() type function kicking around?
Thanks.
Mike.

Yes. It is called ::GetMessagePos() and retrieves the position of the last message. If called in your click handler, you get the position of the click.

Ok, one thing i hate the most about c++ is all the CStrings, strings, CEdits, chars, and whatnot.
I need to make my password (a CString) all into uppercase letters, but i cant just to password.toupper() like i can with a string, because my stupid password has to be a CString.
any help? :^x

I'm not sure I understand,
Why don't you just use the MakeUpper function?
// example for CString::MakeUpper
CString s( "abc" );
s.MakeUpper();
ASSERT( s == "ABC" );

I want to generate a random number between a specified range of 1 to 100, how can I do this?
Thanks in advance, Dave

Technically, you can't generate a truly random number. You can, however, get pseudo-random numbers using rand(). For your specific range, try:
int x = (rand() % 100) + 1;
You may or may not also want to use srand(), which seeds the algorithm.

|
|
Thanks, I'll give it a try.

You'd better initialize the seed first. Use srand(time(NULL)).
Otherwise you will always get the same random number sequence.

Which is not necessarily a bad thing, especially when trying to reproduce a problem.

the question is ?
anyway, you can make the editbox look like a password field by setting a
style in the resource editor.

:-DThank you.
Indeed by changing the setting of the property password from False to True.
As simple as that, yet one needs to know this.
Thanks again
