Blank line in drop down list on resetting

[kpassaur]

I have a drop down list, actully four of them. When I refresh them it appears to disregard the first row which is blank. If I start it with someting that has text in it instead of a blank line "CRLF" it works correctly. Or least appears to. So I tried adding a space and it failed. Below is a portion of the script:

oSub>FolderandFileNameIndex

SRT>FolderandFileNameIndex
Let>blankline=
Let>option1=%blankline%%CRLF%Zone 1%CRLF%Zone 2
Let>DIALOG1.FOLDER1.ITEMS.TEXT=%option1%
Let>DIALOG1.FOLDER2.ITEMS.TEXT=%option1%
Let>DIALOG1.FILENAME1.ITEMS.TEXT=%option1%
Let>DIALOG1.FILENAME2.ITEMS.TEXT=%option1%


If>%SN1%=
Let>DIALOG1.Folder1.ITEMINDEX=0
Endif
If>%SN1%=Zone 1
Let>DIALOG1.Folder1.ITEMINDEX=1
Endif
If>%SN15=Zone 2
Let>DIALOG1.Folder1.ITEMINDEX=2
Endif
If>%SN2%=
Let>DIALOG1.Folder2.ITEMINDEX=0
Endif
If>%SN2%=Zone 1
Let>DIALOG1.Folder2.ITEMINDEX=1
Endif
If>%SN2%=Zone 2
Let>DIALOG1.Folder2.ITEMINDEX=2
Endif


Here you will see I tried to use blankline (normally I just use %CRLF%) but that fails However, it works when it is first loaded and if I change blankline to blankline=test it will work as well. The item index comes back correctly it is as if there are only two items in it. (Zone 1 and Zone 2) The carriage return and line feed are missing.

Any ideas?

Hi kpassaur,

If you could post the whole script that would be helpful but I took a crack at it anyways to see if this is what you are going for.

Code: Select all

let>blankline=
let>defaultoption=%blankline%%CRLF%Zone 1%CRLF%Zone 2
Dialog>dialog1
   Caption=
   Width=445
   Height=250
   Top=508
   Left=1711
   ComboBox=folder1,19,21,145,%defaultoption%
   ComboBox=folder2,22,61,145,%defaultoption%
   ComboBox=filename1,25,99,145,%defaultoption%
   ComboBox=filename2,31,138,145,%defaultoption%
EndDialog>dialog1

show>dialog1

That will load the dialog with a blank line.

Is that what you are trying to do?

Yes, what happens is it loads correctly the first time. The script calls another compiled script, reads some information etc. (it is a very large script) and updates a dialog. (the dialog that contains this). When it reloads the index value is correct; however, the blank line is not there, so it will be moved to the next value. So "Zone 1" becomes index value 0 instead of one.

The part that is confusing me is that if I replace the %CRLF% with a value such as "test" it works correctly.

What happens if you put the system variable %SPACE% in the first line?

ok here is a modified version of my earlier post, it basically updates the first combobox when you click the updatedialog button. It also resets the index value and retains the empty line. I know this is a gross oversimplification of your script but maybe this will help.

Code: Select all

let>blankline=
let>defaultoption=%blankline%%CRLF%Zone 1%CRLF%Zone 2
let>newoption=%blankline%%CRLF%Zone 31%CRLF%Zone 342
Dialog>dialog1
   Caption=
   Width=445
   Height=250
   Top=141
   Left=59
   ComboBox=folder1,19,21,145,%defaultoption%
   ComboBox=folder2,22,61,145,%defaultoption%
   ComboBox=filename1,25,99,145,%defaultoption%
   ComboBox=filename2,31,138,145,%defaultoption%
   Button=update,270,45,75,25,5
EndDialog>dialog1

show>dialog1

label>actionloop
GetDialogAction>dialog1,r
if>r=5
gosub>updatedialog
endif
goto>actionloop


srt>updatedialog

let>dialog1.folder1.items.text=%newoption%
let>dialog1.folder1.itemindex=-1
resetdialogaction>dialog1
END>updatedialog
