Returning subroutine error - Input string was not in the correct format

[HarleyM]

Hi all,
It's been a while since I have been using basic4ppc & visited this forum. In the meantime I can see so much has happened..

Anyway, I have attempted to upgrade a program I was writing in version 4 to version 5. After debugging the initial program errors associated with the new compiller I was able to run the program. Unfortunately I encounter an error during the run which I have never seen before. "Input string was not in the correct format" appears after returning from a subroutine. I have single stepped my way through the subroutine which opens a form which itself opens a subroutine & then another. As I step through the code it returns back along the path closing respective subs until it comes back to the original subroutine call instruction- thats when I get this error. The error allows me to continue & everything seems to function correctly until it comes up again & again as more subs are called. I suspect a stack return problem but can't understand why it would work fine in version 4 & not in 5.

I apologize if this has been covered elsewhere, I searched for it but haven't found what I'm looking for. Any ideas?

Can you post the part of your code that makes this problem?

Sub App_Start
...
If FileExist(Filepath & "Autolog.atl") = false then
fileopen(c1,Filepath & "Autolog.atl",cWrite)
Fileclose (c1)
NewVehicle ()
vehicle.Show
else
fileopen(c1,Filepath & "Autolog.atl",cRead)
s = fileread(c1)
if s <> eof then
for x=1 to 7
i = StrIndexOf (s,",",0)
if i < 0 then
Col(x) = SubString(s,0,StrIndexOf(s," ",0))
x=7
else
Col(x) = SubString(s,0,i)
s= SubString(s,i+1,StrLength(s))
end if
next x
...
FileClose(c1)
LoadData () ' <<<<<<------------------------error occurs here when it returns after doing the LoadData sub
else
FileClose (c1)
NewVehicle ()
Vehicle.Show
end if
end if
....
End sub

Sub LoadData
...
fileopen(c1,OdometerRecs,cRead)
s = fileread(c1)
do while s <> EOF
....
loop
fileclose(c1)
DataRecords.Show
...
End Sub

Sub DataRecords_Show
.....
Set4OdoTab(10)
End Sub

Sub Set4OdoTab(TabRef)
.... 'sets up tabbing conditions for controls in datarecords form
End Sub

could it be that a should be calling my subs without brackets if i'm not passing data...

[Erel]

Yes. You should just write the name of the sub.
