I would consider the following:
Both lists should be virtual, this means that you must provide the information to be displayed as needed by the list control. There are lots of tuts on Code Project regarding virtual lists.
When you load the information from the DB, set the number of rows for each list useing the method I described in my last post. Keep a member variable of the DB, and an index of the current record, as an absolute value. When the list wnats to display a specific row, it will request the item value to be displayed, i.e. row 0, subitem 0, 1, 2, 3, etc. This you can do on the fly, reading the row from the DB, getting the corresponding sub item (field) and displaying it. I know this may seem slow, but it works a treat, as only the information that is to be ACTUALLY DISPLAYED is required.
As for your secondary list that is to display information, I would suggest that you create a query def using the information provided from the main table...

Thanks a lot. So very kind of you to explain in such detail.
I shall change my program to use virtual lists. I am begining to understand them quite well now. I have been running away from it all this while. Lets see if I end up falling in love with virtual lists.
I shall let you know what happens.
Thanks again.

Hai frens,
I need to get only the date info. Need to set time to 0.
// Get the current date.
COleDateTime DateValidTill = COleDateTime::GetCurrentTime();
Wud like to get a better solution than the following.
DateValidTill.SetDateTime( DateValidTill.GetYear(),DateValidTill.GetMonth(),DateValidTill.GetDay(),0, 0, 0 );
|
|
|
|
|
Try:
COleDateTime DateValidTill = COleDateTime::GetCurrentTime();
DateValidTill.SetTime(0, 0, 0);

I have an application which reads a file of particular extension, say, *.abc.
When I run the application and invoke the CFileDialog to select a file of this extension, it opens the file correctly.
Similarly, Dragging and Dropping the file to the application also works fine.
But when I right-click on the .abc file and select Open With... and select my application.exe, the application comes up but it does not open the file.
How should I accomplish this?

Your application need to accept the file path as a parameter when it's run, so typing "yourapp.exe file.abc" on the command line should open the image.

the CFileDialog class doesn't open the file for you. it only provides you an interface (dialogBox) to pick the files you want to open, bu it only returns the absolute paths of these files. only then, when your application gets those files, it has the choice to actually opening them or not.

Well the function returns:
If the function succeeds, the return value is NERR_Success.
If the function fails, the return value can be one of the following error codes.
- ERROR_ACCESS_DENIED The user does not have access to the requested information.
- NERR_InvalidComputer The computer name is invalid.
- NERR_UserNotFound The user name could not be found.
So the thing is I hard code the username and the servername is NULL (servername is NULL, the local computer is used.)
But still the function is not equal to NERR_Success, thus it returns a false.
For example:
============
LPWSTR domaincontroller = NULL;
NET_API_STATUS nStatus;
WCHAR *uni_username = NULL;
uni_username =L"richardb"
nStatus = NetUserGetInfo(domaincontroller, uni_username, 3, (LPBYTE*)&buffer);
if(nStatus != NERR_Success){
retval = NULL;
return false;
}else{
return true;
}
}

I have no idea what could be wrong.

Check you did the following correctly...
Programm3r wrote: WCHAR *uni_username = NULL;
uni_username =L"richardb"
Allocate memory to uni_username and then copy the string...
Programm3r wrote: nStatus = NetUserGetInfo(domaincontroller, uni_username, 3, (LPBYTE*)&buffer);
MSDN says that level 3 is only for servers.. is you pass NULL then your local system should be act as a server..
check what data type your buffer pointing to.. you should use USER_INFO_4
