arrays

[Michael Mattias]

Let me second Cecil's suggestion to learn Windows programming "the API way" before relying on DDT.

Just today I had na application to do; so I sez to myself, "let's try this with DDT".

Well, building the dialog screens and recompiling is a lot easier with DDT; but to do anything really useful you have to understand all the CONTROL SET and CONTROL GET and CONTROL SEND stuff.

Those commands are pretty easy to understand once you've used SendMessage or PostMessage; but absent that experience, I'd still be tryig to figure out where to go next.

Joe,

Take some friendly advice from someone whose just been
through stage 1 of learning Windows and PowerBasic;

1. Get the windows programming books by Petzold and the
one by Rector/Newcomer. These will get you started into
wonderful world of Windows.

2. Dump DDT for now and start learning the Windows API.
Your going to need this believe me. Even DDT is no short
cut to learning Windows, only confusion from my point of
view. Don't get me wrong, DDT is good but LEARN the API
for now then go on.

3. If you didn't get the Docs when you ordered PB, buy the
DOCS. Some useful info in that book!!!

Happy programming,
Cecil

To get the maximize & minimize boxes to show, you need to specify a system menu (and explicitly specifying a caption is recommended)...

    DIALOG NEW 0, "My Program" ,,,250,100, _
      %WS_MAXIMIZEBOX OR %WS_MINIMIZEBOX [b]OR _
      %WS_CAPTION OR %WS_SYSMENU[/b] TO hdlg

Your code has one more serious problem... your TEXTBOX control shares the same ID value as your LISTBOX, so a LISTBOX ADD statement is certain to fail! You must give each control a unique ID. Also,

Next, there is no need to destroy the dialog & recreate it with each additional name. Here is a slightly modified version of your code to show you what I mean (whether it is how you want your application to work like this is a different question!) These mods are not perfect, but it should give you something to go on with.

I am have trubal set an array as global in order to use array data in
more then one sub. I am all so try to put the data in the array in
to a listbox at the cdlick of a button. what do I have to put in
a call back function to make %WS_MAXIMIZEBOX OR %WS_MINIMIZEBOX
show up in the uper right on the dialog box.

here is my program as I have it working now


thanks
Joe
