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?

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.

_T is a macro which needs parenthesis:

wcout << _T("Wallpaper path is:\n") << wszWallpaper;

actually, yes, but not like you do.

use _T macro like this :

wcout << _T("Wallpaper path is:\n ") << wszWallpaper;

BTW, be aware that TCHAR is defined as wchar_t when UNICODE is defined, ,but is defined to char only, if the project is building Single bytes strings...

Thanks Sarath for the help.

But in one seminar , i came to know that the Subsystem that is used in ATM machines is POSIX .It is not Win32.

Is there any such applications exist with OS/2 subsystem ??

Thanks.

any ideas to improve search performance in a tree structure [modified]

George_George7-Jun-06 19:52

George_George

7-Jun-06 19:52

Hello everyone,

I am developing an application which contains a tree structure. The tree structure reflects the management structure of a big company -- child node represents the employees managed by direct manager (parent node), one parent node may have multiple (various) number of child nodes (employees he/she managed in his/her department).

I need to find all the employees a manager managed in the tree structure, the direct child node, the child node's child node, ... and so on (for example, if he is a senior manager, there are multiple levels of child nodes).

Currently, I am using brute force tree traverse approach to print all (direct and indirect) child nodes -- layer by layer. The tree is very large. I am wondering whether there are any good ideas about how to improve the search performance?

thanks in advance,
George
