Hey guys,

My compiled app complains:
On device: InvalidCastException

On PC:

It is running when not compiled.

the Code:

B4X:

Sub put_to_file
   For i = 1 To 4
      If Control("F3TB" & i& "G").visible = True Then
      FileWrite(c1,Control("F3TL" & i).text&"; "&Control("F3TB" & i & "M").text)
      End If  
   Next
End Sub

Can anyone help, please?

Greetings,
Lennart

Can you upload your code (or a subset of it) that demonstrates this error?

You didn't open the file.
I've added this line:

B4X:

Sub App_Start
    Form3.Show
    FileOpen(c1, "1.txt",cWrite)
End Sub

And it appears to work fine.

Which version of Basic4ppc are you using?
Are you compiling with the optimized compiler?
Does it also happen on the desktop (when compiled for the desktop)?

Please download the attached file, unzip it and copy CEnhancedLabel.cs to the Tzor folder which is usually located under:
C:\Program Files\Anywhere Software\Basic4ppc Desktop\Tzor

See if it fixes this problem.
