Out of memory/sys_send_keys

[Henry Gibbons]

As I continue scrabbling my way up the XBasic learing curve, I have run into two problems.

1. I am running A5V4.5 under XP. As I am entering a script into an event, using the Inline XBasic editor, after a while I get an error, "Out of Windows Memory," which prevents me from entering any more code. The amount of code in the window is far less than some of the examples in the book. Can this be corrected or circumvented?

2. I am trying to manipulate the contents of an edit control on a form directly. It's easy to read the contents (stuff = :form:control.text), but when you try to alter the contents of an active control (:form:control.text = stuff) the background goes black and the form locks up. I had also thought of using sys_send_keys, but then stumbled on a behavior which seems bizarre and illogical to me. Let's say you have "abc" in the control and you want to replace it with "xyz." From the keyboard you would use {HOME}shift{END}[to highilight all] and then type "xyz." Now, if you send this sequence of keys via sys_send_keys, the unexpected happens:

sys_send_keys("{HOME}{+END}xyz")

results in "abcxyz", all highlighted. In other words, the letters reach the control first, THEN the control keys. What gives?

I can help with the first problem. Inline xbasic is very limited in the amount of code. When you hit the limit, you get the "out of memory" message. Switch to regular xbasic. While there are limitiation on the amount of code in xbasic, the limitiation is rather huge. The limit is somewhere above 1500 lines.

try breaking it up into three sends - I think it may be misinterpreting what you want

Thanks Jerry. It wasn't immediately clear to me that there was a difference between "Inline Xbasic" and "Xbasic," and that you have to convert Xbasic to Xbasic to get the larger code editing window. The manual is not clear on this distinction.

Speaking of stuff the manuals are not clear on, there are many references to "cards." The index entry for "Cards" in the reference manual refers to page 16, but there is no mention there of cards. Is this old terminology that just hasn't been edited out?

William -

Thanks for the suggestion. I already tried that, but the result is the same. And you can't use the sleep() function, which stops everything. Puzzling.

Henry,

"Cards" refers to saved scripts in Alpha Five, Version 1.

Henry,

If the control is for a field in your table, you don't need to 'select' the text in the control in order to change it. Xbasic simplifies this. Check the Xbasic Reference Manual Ch 15, working with fields.

You will find what you need to 'put' values to a table field, by placing the table in change mode, and using fieldpointer.value_put() (or any of several other methods)

If you're changing the text in a label you can write directly to the control's text or value properties, depending on what you need.

:formname:objectname.text = "xyz"

Tom -

Actually, while looking for something else, I found what this is. Cards - p. 16 in the user manual is a typo - it should read Cards - p. 164. There cards refers to the forms you fill out directly to perform various actions, as opposed to using the Genies, which fill out the cards for you.

Thanks, Tom

I think I was getting messed up in calling a dialog from the OnKey event - when that happens, and the focus moves away from the edit control, it must change the mode. I'm still not entirely clear about the sequence of events. However, I managed to get this to work finally. Thanks for your help.
