This is a vc++ question. I have made an MFC application.

Ah!

It said MFC -- but your question was so vague, I didn't understand what you wanted to do.

You have an app -- with a main panel. You want to create a UI that will let you display records on that panel.

I'm no pro, but:

1. You have to create a UI on this panel to display your data.
2. You have to create SQL statements to get the right data out. Using these statements you have to create RecordSet's which contain the data extracted. You'll have to decide what database interface you want to use -- there's choices like ADO and OLEDB... and other's I assume.

I hope that's a start.
What specifically is your issue here?

hey peter,
my data source is ODBC.
The points 1 and 2 that you have written....well tats fine. My problem here is i know i have to do that(point 1 and 2) but dont know how to !!!

I tried using MS DataGrid 6.0 but dont know how it works...and also i think it is meant for VB(only)...not sure though.....

see if you can help

Why not? Errors? Exceptions? How are you rendering the bitmaps?

Hi,

I designed the image in photoshop and saved it as a .bmp image.. How use it as a skin to a dialog.

With Regards,

An easy way is to draw the bitmap to the dialog in response to the WM_ERASEBKGND message.

Hi Whitesky,

I want to use skin on a dialog.. For that i designed the image using photoshop and saved it as a .bmp image. But how to use it as a skin is my problem. Its not at all getting displayed.. But if i try with 16-bit color bitmap it is getting displayed.. do i have to use some other methods to display it?

With Regards,
Sangeetha.

Hi Whitesky,

Thank u very much.. it works.. the wrong thing i was doing is i didnt use the import option while creating a new bitmap resource in the resource editor.

Thank you,

I know its not a programming related question and is a little OT
but maybe someone will have a idea for this issue,...

Hi Peter,

i dont like cross-posting nor do i like to
ask questions especially on wrong boards, but
as a developer i know that most of use have
a huge knowledge on this area. This is a very
strange and big problem for me, since i didnt
find the problem by my own and it really is hard
to find. I am a experienced developer and
administrator, but this is a very hard thing!

Anyway, thanks,....

Best regards

K.
