I have a text file 36Kb that i would like to open and manipulate. To do this I use:
FileContents = objReader.ReadToEnd()However when I write the manipulated output like so:
objReader = New StreamWriter(FilePath)
objReader.Write(ModifiedContents)
the output file stops mid sentence and is only 32Kb in size.
I am using VB in VS 2008. I am tring to call an external process and redirect the input, and pars the output back to my code.I started with the useal
Dim myProcess As New Process()
Dim StringFromProcess As String
myProcess.StartInfo.WorkingDirectory = (path & "in")

but I will need 4 of them to get to the data and it seem to me its messy coding. Is there a way to get ReadToEnd to work when reading data over TCPIP? Or perhaps a different/better way to read back from my process?

I have an app that calls a DLL, and passes a string to it (by reference). The DLL then fills the string and passes it back to the app. Before calling the DLL, the string must be sized correctly to fit the data the DLL is going to pass it. In the past (using VB.NET 2003) I just initialized the string with the correct number of spaces. This always seemed silly to me and I'm wondering if, in VB.NET 2010, there is a way to do this using a number to define the size?

For my ToDo list I need lots of variables to store data in.Each item of the list has 3 strings in it: Activity, start time and end time.To make multiple tasks in my ToDo list I think it's the most usefull if I use this: 'For x = 0 To 1000', so on the launch it will make 1000 variables to store my data in.But for the 3 string for extra info I need something like this:
x.a
x.b
x.c
Where x is the integer, and a, b and c are the 3 strings. If I try to do this I will need to do 'Dim a, b, c as String', but that way it will not understand x.a x.b and x.c If I do 'Dim x.a, x.b, x.c as String' it gives me an error, because x.a is not a String...
Dim a() As String = {"h", "e", "l", "o"}If a string has a character that is not listed in that array, give an error, how is it possible?

In javascript I know you can put for instance if date= "2010"* which would do the if for the string if it starts with 2010 but it doesn't matter what comes after that.
