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: CODE 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?: CODE Dim startfileName As String = "folder 1.folder 2.Startofhtml.txt" Thanks again -------------------- My website: http://www.aommaster.com

You can use My.Resources in Visual Basic

Hi Billy!
Thanks for your reply. Is this another (programmatically correct) way of doing it? CODE 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? -------------------- My website: http://www.aommaster.com

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.

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
