I have never really done any palm programming but I done allot of programming with several different flavors of BASIC. In izibasic how do you get a second window to open(or even invoke one) and add controls to it and be able to close that and return to the first one. I am having trouble opening another program from a program that I have generated. If anybody could direct to some simple code examples or a collect of public domain snippets that I could to my collection of tools other than the ones that came with the full version of izibasic. Also it would be nice if there was a PC based editor that I could use that was izibasic specific.

 Sorry, dear Khertan, earlier tonight my head had not made the link between the fact that you are a Mac/Linux user and that my PsPad stuff would only wrok for Windows users!

So, have "fun" developing your editor

 This still doesn't work on my PDA Palm OS Version 4.1H. I have substituted the string variable A$­­ or B$­­ into the message box field in place of the C$­­. The VAL function always produces a zero. The message box produces the correct string variable. I am beginning to think the VAL function is not working on my PDA. It won't run on my Emulator either. Should I define some type of global parameters prior to performing mathematical functions?


TEXTFIELD #1, "VALUE 1", 5, 5, 50, 10
TEXTFIELD #2, "VALUE 2", 5, 5, 50, 10
A$­­­­­­=FIELD$­­­­­­(#1)
B$­­­­­­=FIELD$­­­­­­(#2)
A=VAL(A$­­­­)
B­­=­­VAL(B$­­­­­­)
C=A/B
C$­­­­=STR$­­­­(C$­­­­)
MESSAGEBOX (C$­­­­­­,0)

 Hello Watts,

What you get is expected because your source code is not valid.

#1. Please read the brand new Topic #1222 - GUI basic commands

#2. Your TEXTFIELD #1 and TEXTFIELD #2 are put at the same place on the screen, so TEXTFIELD #1 will not appear (it is drawn under TEXTFIELD #2).

#3. iziBasic is not told if values were given in the 2 text fields, so it currently draws the text fields and just after, without giving the user a chance to key in some data in them, retrieves their value and does the calculation.
So, let's add a [Calculate] button and do the calculation only when this button is pressed:
TEXTFIELD #1, "VALUE 1", 5, 5, 50, 10
TEXTFIELD #2, "VALUE 2", 5, 25, 50, 10
BUTTON #3,"calculate",5,45,50,14
REPEAT
 E=DOEVENTS
 IF E=3 GOSUB _CalcIt : E=-1
UNTIL E=-1
END
_CalcIt:

A$­­­­­­­­­­=FIELD$­­­­­­­­­­(#1)
B$­­­­­­­­­­=FIELD$­­­­­­­­­­(#2)
A=VAL(A$­­­­­­­­)
B­­=­­VAL(B$­­­­­­­­­­)
C=A/B
C$­­­­­­­­=STR$­­­­­­­­(C$­­­­­­­­)
MESSAGEBOX (C$­­­­­­­­­­,0)
RETURN


Cheers,
aldweb

 The code I am using is posted bellow. Look at the button named Fuse (handle #6). When I deprees this button I want it to simple perform the simple mathematical operation C=A+B and display it in the message box. It doesnt work for some reasone. Could someone please look at it and tell me what to change.

 Hello,

In the following lines:
NUMFIELD #11,"Driver Impedance(Ohms)",0,5,15,150,10
NUMFIELD #12,"Driver Power(Watts)",0,5,30,150,10

you assign the following initial values for the 2 fields:
"Driver Impedance(Ohms)"
and
"Driver Power(Watts)"
This is where the mistake is, you want these to be 2 LABELs to be placed in front of the value to input in the FIELD.
Then, whatever you key in, for instance:
"10", the value stored will be:
"Driver Impedance(Ohms)10".
When, doing the VAL() conversion, 0 (zero) will be returned as the first character is not a valid digit.

Cheers,

@+

 I have made the changes and it only produces values of the initial values not the values I have placed into the number fields during the program operation. Could you show me exactly what to do.

 Good news.
To make sure, here is what I did during my tests.
I replaced:
NUMFIELD #11,"Driver Impedance(Ohms)",0,5,15,150,10
NUMFIELD #12,"Driver Power(Watts)",0,5,30,150,10

with:
NUMFIELD #11,"",0,5,15,150,10
NUMFIELD #12,"",0,5,30,150,10


Yeah, that's all folks

 not answer but a question.
I'm trying to learn this izibasic.

using the code sample above, why do i get a syntax error on the following line?

C$­­­­­­­­­­=STR$­­­­­­­­­­(C$­­­­­­­­­­)

my logic says it should be

C$­­­­­­­­­­=STR$­­­­­­­­­­(C)

but this doesn't pass either.

any ideas?

 Sure, read the user manual about the STR$­­() function. You will see that there are 2 parameters for the iziBasic STR$­­() function.

So, for instance, doing C$­­=STR$­­(C,-1) will work great

Cheers
