You can use AfxGetCurrentMessage() in VC7.0.

I even wonder how it is compiling. Why are you calling DoModal for a CFrameWnd (which as nothing to do with a CDialog) and how did you proceed to do such a think ?

Maybe, you should use CWnd::GetCurrentMessage or AfxGetCurrentMessage?

I think you can achive the same functionality by calling

CWinThread::GetMainWnd()->GetCurrentMessage() function.

HitTest for CListCtrl

as I understand HitTest should return the index of CListCtrl's item that been clicked, or -1.

CPoint point;
GetCursorPos(&point);
UINT uFlags;
int nIndex=m_lstLeft.HitTest(point,&uFlags);

nIndex==-1... always

GetCursorPos offers the position in screen coordinates, while HitTest requires client coordinates. You probably have to use ScreenToClient function. Try this:

CPoint point;
GetCursorPos(point);
ScreenToClient(point);
UINT uFlags;
int nIndex=m_lstLeft.HitTest(point,&uFlags);

anyway smth wrong..
function returns not index of selected Item.. but index of the item+2(or +3)
I cant understand why..

The suggested ScreenToClient call is for the case you handle the messages within your CListCtrl-derived control. Otherwise, if you are in parent dialog, you should try the solution posted by Steve Echols: m_lstLeft.ScreenToClient(&point).

Please specify in which class you are processing the message.

If your problem is to find the selected (highlighted) item, why GetNextItem(-1, LVNI_ALL | LVNI_SELECTED) is not suitable for you?

GetCursorPos returns the mouse position in screen coordinates.

Try this:

<br />
CPoint point;<br />
GetCursorPos(&point);<br />
m_lstLeft.ScreenToClient(&point);<br />
UINT uFlags;<br />
int nIndex=m_lstLeft.HitTest(point,&uFlags);

What part of this is troubling you? Retrieving date fields from a database is not unlike retrieving fields of other types. You just have to ensure that the variable you retrieve the field into is the correct type.

Like has already been mentioned, retrieving a date field is done just like any other field. What exactly is the problem?

Use SetWindowText() to update a control's text value. This has been mentioned to you several times, too.

What does your CRecordset-derived class look like? Are you using a DSN-less connection?

unicode

Hi,

following syntax has wszWallpaper as unicode string.
wcout << L"Wallpaper path is:\n " << wszWallpaper;

Now wallpaper path is prefixed with "L" to interpret the string as unicode.

can it be prefixed with "_T" as
wcout << _T"Wallpaper path is:\n " << wszWallpaper;

since TCHAR can be used to present ANSI as well as unicode.

Please follow up.
