I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.
Does My.Computer.Network.DownloadFile work with FTP? When I attempt to use it, I get the exception: "The remote server returned an error: (500) Syntax error, command unrecognized."
Here's the code I'm using:
Dim UpdateAddress As String = "ftp://xxx.xxx.xxx.xxx" & lbDownload.Items(X).ToString
My.Computer.Network.DownloadFile(UpdateAddress, BasicPath & lbDownload.Items(X).ToString, "", "", True, 10000, False, FileIO.UICancelOption.ThrowException)
The FTP server is IIS6.

I had the following piece of code working for the last few weeks and earlier today it seems stopped working.I have the code in a try/catchh block and in that try I create a file, "Build.bat" with code in it that will get it to do some oracle/sql wizardry
If File.Exists(Application.StartupPath & "Build.bat") Then
Shell(Application.StartupPath & "Build.bat", AppWinStyle.NormalNoFocus, True)
End If
After stepping through my code I noticed that the catch is executed at the shell line, so I put it in an if statement to see if the file exists and it always comes up as true, but on the next line I still get a File not Found error.
Try
Dim BatFile As New StreamWriter(Application.StartupPath & "Build.bat")

I am reading a file from the default location. I request a file by name only using an InputBox. If the User types a file that does not exist I get an exception error. I want to be able to handle the problem by outputting to a list box that the file was not found. My Code is something like:
sr = IO.File.OpenText(fileName)
IF fileName <> "found"
Handle issue
Else
Continue Code
I want to run a check to make sure the file does exist in the default location but not sure how to get it done. I had seen the Public Shared Function FileExists but I am not quite sure how to make it work.

View 3 RepliesIn the old dos days you could combine 2 files as save to a third file:copy file1 + file2 file3. It still works in a dos shell. I did this: Shell("copy " & file1 & " + " & file2 & " " & file3)I got an error that file3 cannot be found. I know it doesn't exist I want to create it. So I created a bat file:copy %1 + %2 %3 and called it as such:Shell("ccopy " & file1 & " " & file2 & " " & file3). I still get the error that file3 cannot be found. First I don't see how it can tell from the shell that file3 is a file. How do I do this otherwise? Do I have to create a blank file before calling it?

I have a program that looks for a file named 'license.dat' upon startup. The program first checks the directory it's in, and if the license file isn't there, it prompts the user to select the license file with a file browser dialog. I have tested this code and confirmed it working in a number of different OS environments.Recently, I received reports from two users (one in Germany and one in Italy) that the program can't find the license on their computers, even though it is present in the program's directory and they manually selected it with the file browser dialog. The only commonality I'm seeing here is a lack of English OS, but beyond that I'm stumped.This is the code I'm using:
If System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + "license.dat") = False Then

I added a msgbox to show me what the path to the server is and this is it.Click OK and it gives me the error above.So I changed the "ofd.Files.FileName to ofd.Files.SafeFileName My msgbox now shows this:Then VS throws en error saying it can't find the file in the projects debug folder so I move it there and run the program and it uploads. I noticed that in the first msgbox it has forward and backward slashes could that be my problem or is it something else?
Have seen some solutions for C# but do not know how to solve the issue in VB.NET.
Query:
Dim Query = (From t In myEntities.Bookings
Where(t.Ref = Someid)
Select t.People).Sum()
t.Ref field is an Int and so is t.People.
The SomeId value is the primary key of the related table. This issue is that there will not always be records in the Bookings table with a Ref value of Someid - so the query throws the following error.
I have seen others have got around this problem with catching the error, but from reading up on this and as per the error information it seems there should be a solution (in VB.NET) to cast the query or some of the fields in the query to nullable types?
Error is as follows:
The cast to value type 'Int32' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.
