Hi,

I wonder how to achieve a loop with the textboxinput to achieve a number which lies between the acquired numbers.
I want to generate a loop like
DO UNTIL NM<Nr1 AND NM<Nr2 then
NM = textboxNM
LOOP
But this doesnt work. It generates an error. Any ideas?
thank in advance

Well, the prgram doesn't seem to stop when values other then the wanted ones are put in. The reason the program has a parameter RunFirst = evident. The first time the program runs it takes the default values. The second time input is necessary in the sub Initparameters.

I'm sorry but I didn't understand the problem.
What is the meaning of:
B4X:
[SIZE=2][/SIZE][SIZE=2][COLOR=#0000ff]DO [/COLOR][/SIZE][SIZE=2][SIZE=2][COLOR=#0000ff]UNTIL [/COLOR][/SIZE]NR<=MaxRows [/SIZE][SIZE=2][COLOR=#0000ff]AND [/COLOR][/SIZE][SIZE=2]NR>=MinRows
 NR = txtbxRows.Text
[/SIZE][SIZE=2][COLOR=#0000ff]LOOP[/COLOR][/SIZE]
[SIZE=2][COLOR=#0000ff][COLOR=#000000]
[/COLOR][/COLOR][/SIZE]
It will cause the program to hang if the values are not in the range.

Yes, these three loops should take care of the problem that the input is in the wanted range. That was my question.
Now the program doesnt change the input and certainly not within the wanted boundaries. Or should the UNTIL keyword be after the LOOP word?

Why not use a simple If then else...?

If NR<=MaxRows AND NR>=MinRows then NR = txtbxRows.Text

If the AND bit doesn't work try

If NR<=MaxRows then
If NR>=MinRows then
NR = txtbxRows.Text
end if
end if

Ok from what i understsnd you want to set an interval of values from wich the user must enter a number...Right?

I think that in that case you are testing the wrong variable....


You are testing NR before it is set to txtbxRow...

Try this...

If txtbxRows.Text<=MaxRows AND txtbxRows.Text>=MinRows then NR = txtbxRows.Text

Or more complete:

dim n as int16
n=txtbxRows.text
If n<=MaxRows AND n>=MinRows then NR = txtbxRows.Text

Hi Cableguy,

I really DO appreciate your effort but this too doesn't work. Tried the first line myself. Have you tried it in the program? I know you have better things to do but this drives me up the wall........

Ok, I've found the problem a a partial solution...

If txtbxRows.text<=MaxRows AND txtbxRows.text>=MinRows Then
NR = txtbxRows.Text
Else
msgbox("Rows Must be between 1 and 30")
end if


This is only partial because it dos Not STOP execution.

You should check the validation of the values entered in a seperate sub like the lost focus sub, and if the values were good, then lost focus , if not keep focus, after all values were checed move focus to the run button, then in the run_click ckeck for the run button focus....

just my two cents...nahh.... my 2 euros...lol

The other problem is how to stop the program from further execution. this MUST be done by a loop in my view. Returning to the calling sub gives a problem because the first time the sub initparameters is called is before the main page shows. then the parameters must be set by default.
Anyway, we'll give it a try.....

Well, the msgbox pops up but the program continues with the default value. I cannot achieve in getting the right in-out of focus sub to handle the routine.

another sujestion is to set the runbutton,enable=false while the values are not correct....then turn runbutton.enabled=true...I would also sujest to not pre-load values...

The pre-load values are necessary for the first run in which the screen is built up.
I fail to succeed to accomplish your suggestion unfortunately.....
