You should call it like this: pDoc->A.GetResults (result);

I have Create a Flat tab control Lets say CFTabCtrl , Basically a Class derived from CWnd. I have also implemented Drag drop of these tabs now here is the problem,

When My MFC app has got the complete source of this CFTabCtrl, that is this class is compiled with the project, it works fine.( i m refering to COleDataSource::DoDragDrop())

On the second hand I have created another project And Created a Lib file for this CFTabCtrl, and now in my MFC app I am using this CFTabCtrl by including the lib file and ofcourse the header file of the class. Now the whole code is working fine except for that this COleDataSource::DoDragDrop() returns DROPEFFECT_NONE immdiately ..

does any one have any clue what must have went wrong ?

Adding app to Explorer context menu

Hey everyone,

I am working on an application that I would like to show up on the Windows Explorer context menu. I would like it to be like WinZip, where I add a menu item, then when you click on it, it sends the files to my application file list. I assume that I have to use the Shell API, but I didn't see any articles about this. I did see some on how to add Explorer's context menu to your own file list, but nothing to go the other way. Has anyone done this before and, if so, can you point me in the right direction?

Thanks...

I have a list control in adialog box and I want to fill one column of it with a CStringList.This is the function that I use to fill list control.

int CSHowFileDlg::FillListCtrl(CStringList * filelist)
{
	LV_COLUMN   listColumn;
	LV_ITEM     listItem;

	listColumn.mask = LVCF_FMT|LVCF_WIDTH|LVCF_TEXT|LVCF_SUBITEM;
	listColumn.fmt = LVCFMT_LEFT;
	listColumn.cx = 120;
	
	listColumn.iSubItem = 1;
	listColumn.pszText = "File Name";
	m_listCtrl.InsertColumn( 1, &listColumn );

	listItem.mask = LVIF_TEXT ;
	listItem.iSubItem = 1;

	POSITION pos = filelist->GetHeadPosition();
	for(short i = 0 ; i < filelist->GetCount() ; i++ )
	{
		listItem.iItem = i;
		listItem.pszText = (LPSTR)(filelist->GetAt((pos++))).GetString();

		m_listCtrl.InsertItem( &listItem );
		

	}
	return 0;
}

There is no error but it show some of items correctly.Does anybody see anything wrong in this function?

Hi,

A simple MessageBox("Some errors") like this one works well.
But when i use the MessageBox(NULL, str, szMsg, MB_OK), there
is complier error. Where is my mistake?

Thanks in advance!

Your mistake is you're not providing the right argumtns. Check the docs for CWnd::MessageBox.

I guess that the first arg cannot be NULL.

This will work:
MessageBox(strErrorText,strErrorTitle,MB_ICONSTOP|MB_OK);

No, the compiler error is due to the four parameters
used in MessageBox. It seems that i must include some
hearder files or Lib?

If you are calling the message box from inside a CWnd dervied class then you don't need the NULL. It uses the current CWnd object for the parent window.

However you can use the same call by using ::MessageBox(NULL, str, szMsg, MB_OK) which calls the default API version.

Playing an OGG or MP3 in a demo?

22-May-02 0:38

Hi,
is there an easy solution to add music playback to a demo? I think about playing an OGG (or MP3). It would be great if I can name a file and say start, stop or control volume.... DLL or source code. Smile | :)

How are you handling the painting. Does the paint function get called in the mouse leave event?

Posting the portion of the code that is giving you problems would be a great help.

Could it be GlobalFreePtr? I don't find any docs about these macros on the msdn (tell something new Wink | ;)

).

GlobalFreePtr

Note that if you use Win32 there is really no need to use this. The Win32 memory archetecture does not keep a separate global heap. LocalAlloc and GlobalAlloc are the same, and both malloc and new eventually calls a similar function called HeapAlloc.
