Question About List Box Controls

[dicky96]

Hi guys.

I'm just starting on a new windows app and I want to display a list of data in columns .  Here is a .JPG screenshot taken from an app which uses the same sort of Windows Control I want to use in my app.  I'm using a dialog as main window. 

Is this a List Box Control? 

On this example there are buttons to add or deelte an entry, these bring up a child window where the user enters data. As an aside, can I program one like this where the user can type data directly into the spreadsheet style columns rather than using a separate clhild window to add data in text boxes? 

If I can do that, does it make it harder to verify the entered data is valid? 

Once i know for sure which type of windows control to use, I am sure I can go friom there.

Thanks in Advance

The control shown in the scrennshot is a "Listview" control. The questions you are asking seem encouraging as you want to learn and know _what_ you want to do. :U :U
But...I would suggest you to go through the examples and samples to familiarize yourself with Win32 programming and you would be able to do this yourself!

Also do check up on the listview reference from MSDN (if possible).

Cheers and best of luck with whatever you are trying!!!  :thumbu :thumbu

Hello,

It's a listview,that sure.
To create it I can give you the starting point,view the code.
can modify data "on line" directly ?,download  the helper on common controls in the workshop.
The style LVS_EDITLABELS seems to be the answer,try it.

All you have to do with the sample code is:
Put each segment at his place,.const with constants,.data with datas ...
Define the titles (titre) and define the lenght of the title in % of the client area of the listview
The number of titles and the number of lenght must be the same.

The result is a  empty listview with the title you have choose.

Any more questions ?,continue this post.

Thanks guys.  I have written some other apps (well ok.... TWO other apps) in win32asm so I have some idea of what I'm doing....  Well OK, I have a VAGUE idea of what i'm doing  :bdg 

I've just not been around this board for a while, I pestered you lot enough last year with that winsockapp I wote. LOL

Thanks for the code example.  I'll also have a good look at Iczelion Tutorial 31 now.  It's just I was not sure if that thing was a list view control or not, it looks so different from the one when you run Iczelion example.

I'll be back I'm sure.

To be sure what type of control it is you would need to know the "class" of the control, which can be found out using some (any) WinSpy type of application.  :bg :bg

This much info should help you get on your way, I think!!!  :U :U
