For that i have written the following code.
POINT point;
point.x=126;
point.y=83;
HWND hwndListboxDlg = ChildWindowFromPoint(GetParent(hDlg),point);
HWND hwndListbox = GetDlgItem(hwndListboxDlg,IDC_LIST4);
LRESULT iCount=ListView_GetItemCount(hwndListbox);
When i debug the application its find the handle for hwndListboxDlg ,but unable to find the
IDC_LIST4.

Hello!
I am using the following Function to draw text to a screen:
Status DrawString( const WCHAR *string,
INT length,
const Font *font,
const PointF &origin,
const StringFormat *stringFormat,
const Brush *brush
);
Works fine, but there is one major problem : even if I use PointF(0,0) as origin, the text is displayed with an x-offset (the concrete width in pixel seems to depend on the Font-Object I use within the DrawString - Function).
Any Solution about that? Is this a known bug or even a feature? 
Thanks in advance!

How much of an x offset?

As I wrote, it seems to depends on the Font that is in use within the function call.

As the other guy said use COleDateTime, but do not use COleDateTime::GetCurrentTime...
From MSDN...
COleDateTime::GetCurrentTime. The current implementation calls the C run-time function time, which returns a time_t. This limitation isn't currently documented—it presumably took Chris's digging through the Microsoft Foundation Classes (MFC) source code to find it. (As Dr. GUI says, "Use the source, Luke!") Good job. Don't use this function if you need to be year 2038 compliant. Note also that COleDateTime has a constructor and assignment operator that take a time_t—don't use those either.
A suitable replacement will be GetLocalTime.

Hi,
I am working on a project that requires to generate a report after some testing. The report will include some text, one or two pictures and some tables. The dev environment is Visual C++. Did anyone ever work on similar task before? Is there any controls that I can use? Or is there any articles with detailed intro on how to accomplish it?
Thanks a lot!

you mean, like a log file, or you want graphics, statistics, etc...?
have you considered using Crystal Reports then ?
|
|
|
|
|
The report has to be generated directly from the app, and it could be a Word file or pdf file. The content will inlcude text, graphics and tables.

This is the intended behaiviour: The user is asked to close all files on the stick.
When your program has opened the files by itself, it can also close all files from the stick and try dismounting again.
If you have not opened the files, but another process has, maybe you can quit the processes holding the files open?

how are these files opened ?
in general, the application that is opening a file is intended to close it then !
|
|
|
|
|
These files are opened by manually(with keyboard or mouse). I want to close them programatically

this doesn't mean anything. there forcedly and application that holded the opening. if you double click on a text file, the application that opens the file is notepad (or maybe another if you changed the association).
i think you're facing a wrong problem.

What do you mean by "manually"?
Every function that opens a file has a matching function for closing it.
A successful call to CreateFile() will be followed by a call to CloseHandle().
Others are:
fopen() - fclose()
CFile::Open() - CFile::Close()
You cannot force a file handle to be closed from outside a process that has opened a file. The process that opened the file is also responsible for closing it.
