Am not n a programming class am just interested in how things are done behind the scenes while learning. What is nice about this is that you can still learn by looking at code and trying to figure out what/how they figured it out. Am trying to work on this script and looking for some . Am to prompt the user to input a path to a folder in the c: Get a folder object to act as that folder and how to detect if the path which the useer entered is valid and if its not valid to display and error message and to go no further. Get a files collection that represents all files in folder the user selected Check number of files in the collection, it is "0" make a messsage box stating folder doesnt contain files and if it does make a message box stating the number of files in the folder.

I've been all over the help files and finally patched together a VB OleDb connection string for delimited text files:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
"fName" is passed in by an open file dialog.In every case (for all paths) it throws: 'C:1_2010NormalFileNormal.csv' (or where ever it is pointed) is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.Since no path works, it must be a syntax error, but I'll be darned if I can see it.
Full code of this routine is:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
Dim conn As New OleDbConnection(connection)

I have a program where the users generally use UNC paths. For a textbox where they type in a new path to work with, I'd like to be able to make it easy for them by having a button to fire off a FolderBrowserDialog so they can just navigate to it. Alas, I cannot seem to feed it a UNC path as a starting point.

i have a win app in vb2005 but when i want to create a data-source to connect with my database i got this error: The file \CATV-ANTIVIRUSdata|CLINICA_Data.mdf is on a network path that is not supported for database files.
An attempt to attach an auto-named database for file \CATV-ANTIVIRUSdataCLINICA_Data.mdf failed. a database with the same name exists, or specified file cannot be opened, or it is located on UNC share. i need the datasource to start creating datareports but i don't know how to resolve this problem before.
I've searched everywhere to find out why the heck my program is doing this, but couldn't find anything like it...? I'm making a flash card program. Part of my program takes images corresponding to other data from a certain area, chosen by the user, and moves them to another folder, for later use. I want to store the path for the image next to the other data, storing the path as a string. When no image is chosen, the variable for the path is simply "no image".
