Dim file as FileStream = New FileStream("myfile.text", 0, FileMode.Open, FileAccess.Read)
Dim reader as BinaryReader = New BinaryReader(file)
Dim data as Byte() = reader.ReadBytes(CType(file.length, Integer))
Why is the file.length being converted to Byte, when Integer range is greater, and the code not failing to do so? I don't understand.

View 1 RepliesI have an app I created in Vb2010 (my 3rd VbApp) it is a file converter which works but all it does after convert is... I have a converted file but no file name plus it converts within its own directory as opposed to convert in dir where original file location.
So any clues as to how I always use file to converts name as defa and where the converted file will reside same dir as original file?

View 1 RepliesWe have an application that was written in VB6 which I am trying to convert to use the latest VB (Visual Studio 2008), mostly because it's not possible to buy a licenced version of VB6 anymore (personally I'd have been happy to just keep using VB6, but without having a proper licenced version of it, we basically had to chance).The VB6 version I could simply tell it to compile the application and it produced the .exe file which I could then copy onto the server where it was running and replace the old version and then run it.
It seems like such simple things are not possible in VB 2008.I have got the application converted, and if I run it through the debugger it is working correctly, but now I need to get a compiled application to run on the server and can't seem to do it.I have tried using the publish application thing, and nothing I try succeeds in getting a working application.
