Tory, here's a tiny example.
Like Knuth said, there lots of others to look at in SAMPLES.

In the windows GUI enviroment, you will want to provide a button so the user can tell you when his input is ready for you.

In your old MS-DOS BASIC code, the <Enter> key did that by completing execution of the INPUT statement, but there's no such thing as an <Enter> key when entering text into a text control*.

You need to rethink your user interface.. the MS-DOS "linear" model simply does not apply to the Windows GUI ennvironment.

*Yes, I know, but don't you think subclassing is getting a little too far a little too fast?

Tory,

study the provided help file, for this case, look under CONTROL GET ... (retrieve values from controls) and CONTROL SET ... (set values for controls)

You might also want to look at the example source code files that come with the compiler, located in the SAMPLES folder of your installation.

Greetings all,

This may be an elementary question for those of you who are more familiar than I with PB Win 8.0 & PB Forms1.51 and the solution is probably quite simple, but I just can’t seem to figure it out. Back in the day a BASIC program to get a data string from a user and output (i.e. print) that data to the screen was simple and would look something like this:

10 get input a$
20 print a$

Problem is under Windows nothing can be that simple. If I understand correctly, once a program is coded it must be wrapped in a GUI (i.e. run within a window). So, we must create a new dialog (%IDD_DIALOG1). Then we add two textbox controls (%IDC_TEXTBOX1 and %IDC_TEXTBOX2). This much is easy enough, but how do I instruct the GUI to get UserInput$ from TEXTBOX1 then output (i.e. PRINT) UserInput$ to TEXTBOX2 ?

For example, think of a simple Instant Messenger program, chat program, or even a telnet/MUD client. All of these types of programs need to get UserInput$ from one textbox then display UserInput$ to a secondary textbox. At least, I assume this is typically done within two textboxes. Perhaps I am wrong, or maybe there is a better way of achieving the same effect.

An actual example of code is preferable to an explanation of how this can be achieved. If I have the code, the explanation should be self-evident. However, I appreciate any help you may be able to provide.
