Running an embeded EXE .NET 2013

Tue, 14 Oct 2014 12:48:59 +0000

Hi.

I'm currently working on a new project for working with .PK3 - .DMD & .MD2 files.

Now, I have an EXE (cv.exe) that I would like to embed into my program and execute through the routine below.

I've tried different methods found on the internet without any luck.

Code:
' This routine runs MD2Tool with the selected tasks. (Convert)    

Private Sub RunMD2tool(ByVal path As String, ByVal file As String, ByVal tasks As String)    

Dim p As New Process()    

Dim infs() As String = {"""" & path & "\" & (file) & """" & tasks}    

With p.StartInfo    

For f = 0 To infs.Count - 1    

.Arguments = infs(f)    

.FileName = "cv.exe"    

' Hide the window ?    

p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden    

p.Start()    

Do While Not p.HasExited    

Application.DoEvents()    

Loop    

Next    

End With    

MsgBox("Convertion complete.")    

SinglePath.Text = Nothing    

Label7.Text = Nothing    

End Sub

Many thanks for your help.

NullReferenceException when adding item to generic list

Thu, 17 Apr 2014 19:28:07 +0000

I have a little problem that I can't seem to solve.
When I try to add a value (integer) to a generic list (of integer), I always get a NullReferenceException.

This is my code:
[code2=vbnet]Dim listIndexes As List(Of Integer) = Nothing
For Each i As ListViewItem In Me.listKeys.Items
For Each i2 As ListViewItem In Me.listKeys.Items
If i.Text = i2.Text Then
listIndexes.Add(i.Index) 'The error persists here: NullReferenceException
listIndexes.Add(i2.Index) 'and propably an error here too
End If
Next
Next
Me.SelectKeys(listIndexes) 'This line just selects the items in the listview[/code2]

I've discovered that the index of these two items in the listview are both zero.

Hope someone can help,

Auto-generating Drop Menus from User Input

Mon, 27 Jan 2014 00:56:08 +0000

I was hoping someone could help me with this. I am semi-experienced in coding, but I'll let you know if I don't understand something.

I want to make the drop down menus under the menu strip buttons have traits/names based on previously entered information from text boxes.

I'm trying to make a trading system for a game. So under the Trade tab, I would like it to list the names of the players that are entered manually in separate text boxes beforehand. Then, in each name, have the submenus generated by other previously entered information.

I hope this is explained well enough.

Thanks to all who reply! (If you need images, just request them)

Problems with dividing a string

Sat, 19 Oct 2013 20:09:27 +0000

I have already another question, I'm not asking how to do something for a change.

I have written something but it seems that it doesn't work properly and I don't know what the problem is.

The purpose of the code is to divide a key (length of key can varie) into parts of each 4 characters.
[code2=vbnet]Dim strings As New List(Of String)
'Just an example of the key, this string will be generated randomly
Dim s As String = "p6s0arJHmuOQmUhIczfnynRS1dOrRxYm0EF05b5Vk1YR7TQVItShNjFJQ1L3d"
Dim i As Integer = 0
Dim intMaxNumber As Integer = CInt(Math.Round((s.Length / 4), 0))
For i = 0 To intMaxNumber Step 4
strings.Add(s.Substring(i, 4))
Next
For Each srtininglist As String In strings
MessageBox.Show(srtininglist)
Next[/code2]
Everything goes fine when I debug it but it seems that the code only returns 4 parts, and it should (in this case) be about 16 parts.

I'm probably making a logical mistake but I can't figure out what I'm doing wrong.

Hope someone can help me out,
Brecht

Rename application file

Sat, 12 Oct 2013 14:25:19 +0000

Hi

Is there a way of renaming the application file itself while it is running? I saw somewhere a code snippet to do it and I think it is possible but I can't remember how.

Usage value of properties

Sat, 31 Aug 2013 14:13:13 +0000

Hi, I have a little question here

I'm using a lot of properties but I don't know what value to use in my other subs. I find it hard to explain so I have an example:

[code2=vbnet]'This is the property itself
Private _TextCancelButton As String = "Cancel"

Public Property TextCancelButton() As String
Get
Return _TextCancelButton
End Get
Set(value As String)
_TextCancelButton = value
cmdCancel.Text = _TextCancelButton
End Set
End Property[/code2]

Now what should I use know to change the text of the Cancel button, for example when another button is clicked?

[code2=vbnet]cmdCancel.Text = _TextCancelButton
'or
cmdCancel.text = TextCancelButton[/code2]

I think it is the same, or not?

Thanks, Brecht

Downloading from FTP server doesn't work

Mon, 12 Aug 2013 16:50:59 +0000

I have been working on a little project that requires downloading a file from an FTP server. The problem is that it just doesn't want to work. I have uploaded my project so you guys can read the whole code because I found a library online.

Also you can acces the FTP I'm using for this test project, it is just a test server so you can't acces any of my normal files, only the file that has to be downloaded.

Now the problem; in this test project I created two buttons, the first one downloads the file with the standard future of VB.NET(FtpWebRequest). The problem is that it says that the file is downloaded but the file isn't saved anywhere on the harddisk.

The second button downloads the file using the library I've found online. Everything goes fine until it gives me the error that the file doesn't exist or that I don't have the rights to acces the file (Error code 550).

I had some more problems with downloading this file but found a solution by myself but this just won't work. I really have no clue on what I'm doing wrong.

Hope someone can help me with this one,
Brecht

Building or Publishing

Wed, 07 Aug 2013 16:13:24 +0000

I have a little question but didn't know where to place it on the forum. Because this is about programming I decided to place it here, hope it's the right place...

So my question is what the difference is between the executable that has been built or the executable that has been published. Except from the installer where the published exe is stored in I don't know the difference.

Thanks, Brecht

Exceptions help

Sun, 04 Aug 2013 16:28:05 +0000

Hello everyone

I have two questions that are bothering me now for a long time but can't find any answers to it. These questions are about Exceptions in VB.NET.

- I know what the Try...Catch block does, it catches any errors, but how far do you have to go? For example you want to open a file but it is
possible that the file doesn't exist then you use the Try...Catch, I know that. Is it also needed for example changing the text of a textbox or editing items in a treeview...

- The second question is about the Finally block. Let's say we've downloaded a file but there occurres an error during the downloading process, the Catch block catches the error... and then I want to remove the downloaded file if it exists. Then there is a possibility that the file doesn't exist so if I write

Code:
My.Computer.DeleteFile(pathFile)

in the Finally block it throws a second exception right? or does VB.NET take care of that automatically?

Thanks, Brecht

I recently downloaded Bass from http://www.un4seen.com/ and I am trying to figure out how to stream audio from a url with it and make a visualizer. I haven't been able to find a single tutorial and it is driving me insane.
