I have two computers, desktop and a laptop. Both computers have their own version of Access. The database is stored on the C: of the desktop and is used from either the desktop or the laptop.
I have a button that converts a report to a pdf and then puts the pdf in a specific file folder using the date & time as the file name.
The button works find from the desktop, but does not work from the laptop. From the laptop the button will open up the report but that is where the process stops.
Not sure what is missing here, but I would guess that I need something in the file path to distinguish the two computers, or more precisely I need to label so that the pdf document ends up in the desktop and not the laptop as both computers have a c:
Public Sub tabExportPDF_Click()
Dim ToDate As Date
Dim CurrentTime As String
Dim NetWorkPath As String
Dim ExportPath As String
ToDate = Date
CurrentTime = Format(CStr(Now), "hh-mm_ampm")
NetWorkPath = "c:\Users\DHPA\Documents\Digby Harbour Port Association\DHPA Database\Maps\"
ExportPath = NetWorkPath & "\" & "Map_" & ToDate & "_" & CurrentTime & ".pdf"
On Error GoTo ErrHandler
DoCmd.OpenReport "rptMap", acViewPreview
DoCmd.OutputTo acOutputReport, "rptMap", acFormatPDF, ExportPath
DoCmd.Close acReport, "rptMap"
MsgBox prompt:="PDF File exported to: " & vbNewLine & NetWorkPath, buttons:=vbInformation, Title:="Map Exported as PDF"
ErrHandler:
If Err <> 2501 Then
End If
End Sub
You could use the following, just insert proper computer name (of your desktop pc) in place of TargetComputerName
NetWorkPath = "\\TargetComputerName\c$\Users\DHPA\Documents\Digby Harbour Port Association\DHPA Database\Maps\"
ExportPath = NetWorkPath & "Map_" & ToDate & "_" & CurrentTime & ".pdf"
From the comments bellow, on the desktop PC Documents folder is shared probably, so if you are running the code from the laptop, it should use the 2nd path.
If UCase(Environ$("computername")) = "MAIN" Then
NetworkPath = "\\MAIN\c$\Users\DHPA\Documents\Digby Harbour Port Association\DHPA Database\Maps\"
Else
NetworkPath = "\\MAIN\Documents\Digby Harbour Port Association\DHPA Database\Maps\"
End If

I've been working on a script, a windows console application, that reads a .CSV for a file-path and other various information and then using System.IO.File.Copy to copy the file to a new directory and give it a new name. The file's im working with are .WAV files. Essentially I take a peek at the .CSV provided, then grab the filepath from there, then rename the file using different columns from the .CSV with dot-notation. I.E. Acc.Date.Name.Type.wav.
However, I'm experiencing "NotSupportedException" error on the line that copies and create the new file. The sub message is "The given paths format is not supported." Now, I've fairly new to VB code, I' assuming right now that .WAV format is not supported.
I'm not sure what all to add, if anything is needed let me know.
Here is the script so far:
Module Module1
Sub Main()
Dim fileLine As String
Dim aryTextFile() As String
Dim objReader As New System.IO.StreamReader("C:\Temp\EDCallFilePaths.csv")
Do While objReader.Peek() <> -1
fileLine = fileLine & objReader.ReadLine() & vbNewLine
aryTextFile = fileLine.Split(",")
If Not aryTextFile(7) = "null" Then
System.IO.File.Copy(aryTextFile(7), "C:\Temp\" & aryTextFile(0) & "." & aryTextFile(2) & "." & aryTextFile(3) & "." & aryTextFile(4) & "." & aryTextFile(5) & "." & aryTextFile(6) & ".wav")
fileLine = ""
End If
Loop
End Sub
End Module
I should note, column 7 is the filepath to the recording
I have used dotnetbar devcomponents advanced treeview to create multiple directory trees for one of my projects. Functionality wise, everything is working fine.
I have now added images to the directory file nodes (e.g. pdf image if its a pdf file) and published the application. The application runs without any errors first time on any machine, but once I close this File Management form (I have a control panel form with buttons that is the initial startup form. The buttons take me to other forms. On button click, it hides the control panel and displays the corresponding form through showdialog - File Management form is one of those buttons) and reopen it again - I get the following error:
parameter_is_not_valid
It then fails to load the nodes and after a couple of tries, Microsoft .Net Framework window appears and ends the application.
I get the images from my resource file. Please see the code for LoadAllSubDirectoriesFiles where the error occurs:
Private Sub LoadAllSubDirectoriesFiles(ByVal uParent As DevComponents.AdvTree.Node)
' Initialise Error Checking
Dim uStackframe As New Diagnostics.StackFrame
Dim ufile As IO.FileInfo = Nothing
Try
If uParent.Name.Length <> 248 Then
Dim files As IO.FileInfo() = uParent.Tag.GetFiles()
For Each file As IO.FileInfo In files
If (Not file.Attributes.ToString.Contains("Hidden")) Then
Dim uNode As DevComponents.AdvTree.Node = New DevComponents.AdvTree.Node()
uNode.Tag = file
uNode.Name = file.FullName.ToLower
uNode.Text = file.Name
If file.Extension = ".msg" Then
uNode.Image = My.Resources.Resources.Mail3
ElseIf file.Extension = ".txt" Then
uNode.Image = My.Resources.Resources.Document
ElseIf file.Extension = ".pdf" Then
uNode.Image = My.Resources.Resources.pdf

End If
uNode.DragDropEnabled = True
uParent.Nodes.Add(uNode)
End If
Next
End If

I have spent 2 days now trying to figure out the cause and fix for this problem. There were posts that talked about the image being disposed and not being able to retrieve the image reference [ http://blog.lavablast.com/post/2007/11/29/The-Mysterious-Parameter-Is-Not-Valid-Exception.aspx ] , cloning the image before disposing etc.
I have given disposing and cloning a go, but the error still stands. Been trying couple of other things, but still unsuccessful.
Any suggestions to what is wrong?
EDIT 1
Before closing the form, I clear all the treenodes and then use Me.Close()
Private Sub tsbClose_Click(sender As Object, e As EventArgs) Handles tsbClose.Click
atRootFolder.Nodes.Clear()
atAllDirectories.Nodes.Clear()
atScannedFiles.Nodes.Clear()
atFiles.Nodes.Clear()
atInbox.Nodes.Clear()
atSent.Nodes.Clear()
Me.Close()
End Sub
EDIT 2
My treeviews have hundreds of nodes, child nodes etc. Please see the image of my File Management form ( this is the first time it was loaded, no errors) I had to hide the text due to client confidentiality, but I hope it makes sense. Each image is a node.
imgur.com/QQ2FzFV
I had tried to use GC.Collect to see if it works, and surprising it did. Sadly it worked on one machine and didn't in another. Therefore, instead of calling images directly from my resources, I have stored all required images in an image list which I have attached to my treeviews. It's working like a charm.

I am working on 64bit Windows but the code is compiled for 32bit Windows (for compatibility). If I run the code compiled for 64bit , i have not problems with the code, but if I run it compiled for 32bit I get the FileNotFoundException :
A first chance exception of type 'System.IO.FileNotFoundException' occurred in System.dll
System.IO.FileNotFoundException: C:\Windows\system32\csrss.exe
at System.Diagnostics.FileVersionInfo.GetVersionInfo(String fileName)
at WindowsApplication1.Form1.Button1_Click(Object sender, EventArgs e) in C:\Users\Maximus\Documents\Visual Studio 2010\Projects\rupe\rupe\Form1.vb:line 81
And I don't know how to fix it. Can you help me please ? Thanks in advance.
I cannot seem to find an exact answer to this but I am quite sure that the problem is that 32bit processes do not have permission to access the modules of a 64 bit process. This is why you have no problems with your 64bit app but the 32bit app doesn't like certain processes. The best resource I could find for this was another SO question which you can read here: System.ArgumentException and System.ComponentModel.Win32Exception when getting process information.
That being said there doesn't appear to be a way to get the file information for these 64bit processes when you are running a 32bit app. If you absolutely need this information you have no choice but to build your app as 64bit. If you don't really need this information and want to just carry on with the processes that you have access to in a 32bit app you can try something like this:
Private Sub FindMicrosoftProcs()
Try
Dim searcher As New ManagementObjectSearcher("SELECT * FROM Win32_Process")
For Each p2 As ManagementObject In searcher.Get()
If p2("Name") <> "System" Or p2("Name") <> "System Idle Process" Or p2("Name") <> Process.GetCurrentProcess.ProcessName & ".exe" Then
Dim x As String = p2("ExecutablePath")
If Not x Is Nothing Then
If x.Length > 2 Then
Dim fvi As System.Diagnostics.FileVersionInfo
Try
fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(p2("ExecutablePath").ToString)
Dim sDescription As String = fvi.CompanyName & "/" & fvi.LegalCopyright & "/" & fvi.LegalTrademarks & "/" & fvi.ProductName & "/" & fvi.FileDescription & "/"
If sDescription.ToLower.Contains("microsoft") Then
MicrosoftProcs.Add(p2("ExecutablePath"))
Debug.WriteLine("Microsoft process : " & p2("ExecutablePath"))
End If
Catch ex As Exception
nSkipped += 1
End Try
End If
End If
End If
Next
MessageBox.Show("Found " & MicrosoftProcs.Count & " and skipped " & nSkipped & " files.")
Catch ex As Exception
MessageBox.Show("Error: " & ex.Message)
End Try

I am trying to take text fields for old hostname, new hostname, username, and password and remotely change computer names. That part is working fantastic. It was all great until my manager saw it in action, since we have a policy against downloading and using freeware.
It's not freeware if I made it. Unfortunately, he sent it to my director, and know my director knows I know a little bit about Visual Basic, so he wants to loop the names from a CSV file, change the name, and send a message to the end user instructing them to save their files and reboot.
Unfortunately, net send has gone the way of XP since Vista. However, from Vista - Win8.1, there's a utility called msg.exe in C:\Windows\System32. In order to use it, the target computer has to have the registry value AllowRemoteRPC in HKLM\SYSTEM\CurrentControlSet\Control\Terminal Services set to 1.
So here's what the app does:
Reads the DWORD key AllowRemoteRPC and stores it to a variable (MyVal), changes the key to 1, attempts to send the message alerting the user they need to restart, changes the key back to MyVal, and then executes netdom renamecomputer and renames the PC. Everything works perfectly EXCEPT sending the message. I can open up a command prompt and type:
msg /server:hostname * /v /time:3600 "my message here
And it works perfectly (after manually editing the registry key to the needed value).
However, running it from VB doesn't work. Here's what I've tried:
"msg /server:" & hostname & " * /v /time:3600 ""my message here"""
"cmd.exe /D /c msg /server:" & hostname & " * /v /time:3600 ""my message here"""
Neither seems to work. I know the registry value is being changed. I put message boxes after each step in my and refreshed the regedit to actually see the value of the DWORD key, and it is changing. Everything APPEARS to be going smoothly, the message is just not getting sent.
I do have these commands running as arguments to a function I created in order to create a process so I could output the streamreader to a listbox.
Here's my code. Please keep in mind, I'm barely over 2 months into learning visual basic, so it's probably not the prettiest code out there:

What do you know. There's actually nothing wrong with my code at all. While trying to play around with the paths variable, I decided "Fuhgeddaboudit, I'll just add the executable to the project!". Right clicked the project, Add -> Existing Item. Selected Executable as the type, and went to C:\Windows\System32 and, get this now, msg.exe wasn't there. At all. Opened Explorer and went to System32, msg.exe was there. For whatever reason, Visual Studio cannot see the program at all. Which is in and of itself weird.
So I copied msg.exe to my desktop, added it to source, the program works like a charm now.
I'm currently using the Directory.Move method to copy files from one location to another. What i would like to do is only move files with certain extensions (.dbf, .ini & .txt). If the original folder doesn't contain any of these files then i just want to create an empty directory
Current code I'm using is...
Dim n As Integer
If lb1.SelectedItems.Count = 0 Then Exit Sub
For n = 0 To UBound(AllDetails)
If AllDetails(n).uName & " - " & AllDetails(n).uCode & " - " & AllDetails(n).uOps = lb1.SelectedItem Then
If Not My.Computer.FileSystem.DirectoryExists(aMailbox & "\" & AllDetails(n).uFile) Then
Directory.Move(zMailbox & AllDetails(n).uFile, aMailbox & "\" & AllDetails(n).uFile)
lb3.Items.Add(AllDetails(n).uName & " - " & AllDetails(n).uCode & " - " & AllDetails(n).uOps)
Else
lb3.Items.Add(AllDetails(n).uName & " - " & AllDetails(n).uCode & " - " & AllDetails(n).uOps)
Exit Sub
End If
End If
Next
All the variables are declared and this works but moves the entire folder contents
One way to approach this is to use each extension as a search pattern for File.GetFiles, then use Directory.Move on each file returned. Something like this might help:
For Each OldFile As String In (From s In {".dbf", ".ini", ".txt"}
From f In Directory.GetFiles(zMailbox & AllDetails(n).uFile, s)
Select f)
Directory.Move(OldFile, aMailbox & "\" & AllDetails(n).uFile & "\" & Path.GetFileName(OldFile))
Next
if what you want is certain file extensions only? well Open File Dialog can filter that for you
Let's say you call this operation with a button click:
Dim fd As OpenFileDialog = New OpenFileDialog()
fd.Title = "Open File Dialog"
fd.InitialDirectory = "the initial directory you want to look at first"
'this filters the available files to be opened!
fd.Filter = "dbf files|*.dbf*|ini files|*.ini*|Text files|*.txt*"
fd.FilterIndex = 2 'set's the default files to open first as .ini
fd.RestoreDirectory = True
If fd.ShowDialog() = Windows.Forms.DialogResult.OK Then
'Copy the file to the location using the copyer subroutin
resulta.Text = fd.FileName.ToString
Copyer(fd.FileName.Tostring, "the location where you want to copy")
End If
End Sub
Now for the copying of the file, have a look at this subroutine. This subroutine checks first if the file exists. If it does, it deletes it, then copies the new file.
Public Sub Copyer(ByVal theFile As String, ByVal Lokasyon As String)
Try
Dim resultpath As String = Lokasyon
If System.IO.File.Exists(resultpath) = True Then
System.IO.File.Delete(resultpath)
'this deletes the file so you can overwrite it.
End If
My.Computer.FileSystem.CopyFile(theFile, resultpath)
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
Please let me know if this has helped you.
