Strange errors when importing text files

[vecino]

Hi, I'm having some strange problems when performing an import of a text file into a database.
The errors are not always the same, sometimes get an error of the structure of the text file, sometimes the screen turns off the tablet and minutes later android message says that the application has been forced to stop. Several text files, sometimes happens with some and sometimes with other, I'm desperate and do not know what to watch.
I think with the screenshot that I can explain a little problem, I do not know what other information to provide can help me.
Thanks and regards

Hello, has been solved by putting this code inside the loop.

iReg = iReg+1
If (iReg Mod 10)=0 Then
  DoEvents
End If

Thanks and regards.
