BleepingComputer.com: VB .Net, Embedded text files, and assemblies

Hi guys!

I'm new to VB .Net (I can do the basic things like writing up functions, and simple events) and I decided to add a function to a piece of already-written code.

I have a text file in the root of the project which I have set as "embedded resource", which I believe is a step in the right direction .

I'd like to input the whole text file's contents into a string.

My code is as follows:

		Dim startfileName As String = "Startofhtml.txt"
		Dim Asm As System.Reflection.[Assembly] = System.Reflection.[Assembly].GetExecutingAssembly()
		Dim strm As Stream = Asm.GetManifestResourceStream(Asm.GetName().Name.ToString() + "." + startfileName)
		Dim reader As StreamReader = New StreamReader(strm)
		Dim preview As String = reader.ReadToEnd()

My problem is with line 4 of the above code when it says that StreamReader is trying to read a null value. Now, I'm guessing that it's hit a problem with trying to use the resource, so I'm guessing I haven't done something right with respect to finding the namespace. However, I'm not sure.

Also, say I put this startofhtml.txy in folder 2, which is located in folder 1 which is located in the root. Do I define the startfilename as follows?:

Dim startfileName As String = "folder 1.folder 2.Startofhtml.txt"

Thanks again

You can use My.Resources in Visual Basic

Hi Billy!

Thanks for your reply. Is this another (programmatically correct) way of doing it?

		Dim res() As String = GetType(Form1).Assembly.GetManifestResourceNames()
		Dim stream As System.IO.Stream = GetType(Form1).Assembly.GetManifestResourceStream(res(0))
		Dim stream_reader As New StreamReader(stream)

		Dim preview As String = stream_reader.ReadToEnd()

Or is this not a correct technique to apply in such a case?

You can.... it's just easier to use the My. namespace IMHO. So long as your code works I don't think there's much of a difference. Using My. just has Visual Basic take care of the nasty work for you.

EDIT: Though I have not tested the above code.

Hi Billy!

Yeah, the code that I initially wrote worked, although the res index number kept changing. I finally figured out how to you the My.Res properties and am using that now, since yes, they are a lot easier to take care of

Thanks again Billy
