The Pager Control

Sup guys :),

To start off with(my posting) I'd like to ask how to work with a pager control, so could someone please post a (Win32) piece of code showing me how to succesfully create the control. Here are the guidlines -

- There needs to be three buttons in the pager control
- And that's it :ooh:

Thanks :icon_twisted:.

Re: The Pager Control

I don't know anything about win32, but I do know that you're going to have to be a lot more specific if you expect any useful responses.

Re: The Pager Control

I don't know what a pager control is but there is a lot of information about them. If you had bothered to use google you could have saved yourself a lot of time.

Re: The Pager Control

Well guys I did bother but you get info about pager controls that are relative to other programming/web langues... If you were to try and type down something like "C++ Win32 Pager Control" you would get unrelated results... You get a lot of MFC related example but like I said no Win32 info :( which is why I posted.

Has anyone got any idea?

Thanks for the help/posts :).

Re: The Pager Control

If you found one for MFC then it should not be difficult (probably) to port to pure win32 api functions. Afterall, MFC is just a wrapper for win32 api. Post link and I'll see what I can do to help you out.

Re: The Pager Control

Thanks for another post!!! :)

And here's one link now - http://www.codeguru.com/cpp/controls...cle.php/c2199/

Its not even close to what I would expect... If you don't mind could you please create an example with guidlines from above? Here's some of it done already -

/*
--------------NOTICE-------------
As far as I know all I need to do now is to handle a message which is think was PGM_CALCSIZE or so.
But I do not know how :( So I'm hoping that you can help me.

Re: The Pager Control

After a little bit more of work I figured out how to size it properly but now the problem is that the pager control acts up wierdly -

Any ideas?

Re: The Pager Control

I think you are misusing the pager control. From what I see and understand the pager control is a container for another object that is too big to see all at one time. You can only put one other control on the pager control as explained here. You are attempting to put three buttons on it. What you may want to do is create a toolbar control, but all the buttons on that then add the toolbar to the pager control.

Re: The Pager Control

Thanks for your reply but man I hate toolbas because they are hard to use! Oh well, no pain no gain I guess :)

Thank you!

Re: The Pager Control

Man I already got some trouble! I can't seem to find out how to assign a button to the toolbar, I keep searching but come up with resources which show how to assign images which is not what I need. :)

Please help! :|

Thanks !!!
