Merge Files - Error: File Cannot Be Found
Jun 6, 2005In 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?

View 1 RepliesAsp.net - Property Was Not Found On The Entity During An Insert, Update, Or Delete Operation?
Apr 6, 2011I have a GridView that is tied to an EntityDataSource. Most columns are normal bound columns, but two are itemtemplates. When I attempt a delete on one of the rows I receive the following message:
"A property named 'Building1.building_name' was not found on the entity during an insert, update, or delete operation. Check to ensure that properties specified as binding expressions are available to the data source."
I'm not sure how it is possible that this isn't available, since it displays the element just fine when I'm just viewing - it just throws the error when I attempt deleting a row?

Shuffling Items Inside A Movie List / Need To Delete Half List
May 16, 2011Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.

View 1 RepliesCOM Files Cannot Be Found By The System
Nov 4, 2009I'm having an issue that, frankly, I don't understand. I've been developping a VB.NET application for months and today, when I open the solution file, and tried rebuilding it, I am getting several errors, all various permutations of "The referenced component 'SOMETHING' could not be found." There are 5 COM objects that it cannot seem to load (Excel, Office.Core, VBIDE, Word, and OISSERVERLib).
When I go into the References section, I see next to those COM objects, the path is now shown as "<The system cannot find the reference specified>". I've followed the steps outlined here, including updating the reference paths to directly point to the files, but nothing seems to be fixing the issue.
Does anyone know what could be causing this, or (even better) how to fix it? This is the first time in 4 years that I've encountered an issue like this.
I've attached a zip file containing a screen print of Visual Studio showing the errors.

Binary Files - Read Characters Until 0 Found
Sep 23, 2011I am trying to make a program in Visual Basic 2010 that should do the following:
-Open file as binary
-Start with position 57 and read the following characters until a 0 is found, print the whole name
Inside the binary file, all the files' names end with 0 (which should not be printed), example:
B000000.dat0
eft.dat0
G000000000.b70
For the above examples, the names that should be printed are B000000.dat, eft.dat, G000000000.b7 respectively. The code I wrote is below. The problem is that i am not sure how to read the name until the 0 is found since the names are variable in length and so are the extensions(dat, b7). Also some names have 0 in them which makes things difficult.
Using gs As New FileStream(fileName, FileMode.Open)
gs.Position = 57
Using gr As New BinaryReader(gs)
For x As Int16 = 57 To 70
Dim textvar(x) As String
textvar(x) = gr.ReadChar
text3 = textvar(x) & (gr.ReadChar)
Next
End Using
End Using

Apr 17, 2010I have following code somewhere in my VB.NET 2008 program to create an array of files found in a folder:
Dim objFolder As New IO.DirectoryInfo(strXMLImportPath)
Dim arrXMLFiles2Import As IO.FileInfo() = objFolder.GetFiles("*.xml")
...
UpdateFileQ(arrXMLFiles2Import)
[Code] .....
When setting "option strict" to on, I'm getting following error on the line:
lbFileQ.Items.AddRange(dirlist)
Overload resolution failed because no accessible 'AddRange' can be called with these arguments:
'Public Sub AddRange(items() As Object)': Option Strict On disallows implicit conversions from 'System.Array' to '1-dimensional array of Object'.
'Public Sub AddRange(value As System.Windows.Forms.ListBox.ObjectCollection)': Value of type 'System.Array' cannot be converted to 'System.Windows.Forms.ListBox.ObjectCollection'.
Although everything works fine with option strict set to off, I'd like to correct this problem. Also note that array "arrXMLFiles2Import" is used later on in the program, so I can't change anything on that.
