The System.IO namespace has the classes you need to read files. I think that My gives you a shortcut as well. System.IO.File.ReadAllLines will read your file into a string array, a string per line. You can then call the Split method on the string class to turn each line into a string array ( split on space ). Then double.TryParse can be used to find all the numbers, and you'll always know that the last element is a string, so treat that accordingly.

my be you should try file manipulation..
ex:
While yourFileHandler.Peek <> -1
yourArray = split(yourFileHandler.Readline()," ")
For i as Integer =0 to Ubound(yourArray)
'yourArray(i) do assigning the value of array here into your datagrid
Next
End While

Here is some bits of code (not complete) I have used to do somthing similar.
1) it opens the launch.ini file
2) creates a streamreader and puts the content of the file into infile
3) then it reads infile one char at a time building a temp string until it reads a comma (in your case it would be a space)
4) On reaching a comma it stores the value in a string (in the example IP and Mac)
Hope this helps you get started.
thefile = "c:\launch.ini"
Try
fs = New FileStream(thefile, FileMode.Open)
Catch excep As System.IO.FileNotFoundException
Exit Sub
End Try
Dim sr As StreamReader = New StreamReader(fs)
Dim infile As String ' String used to accept file input
Dim c As Char
Dim count As Integer
Dim temp As String
infile = sr.ReadToEnd
sr.Close()
fs.Close()
'MessageBox.Show(infile)
count = 0
Do
c = infile.Substring(count, 1)
count = count + 1
If c <> "," Then temp &= c
Loop While c <> ","
ip = temp
ipbox.Text = ip
temp = ""
Do
c = infile.Substring(count, 1)
count = count + 1
If c <> "," Then temp &= c
Loop While c <> ","
mac = temp
macbox.Text = mac
temp = ""

Can anyone tell what is the vb.net code for displaying an image using microsoft office document imaging viewer control 11 and how to zoom in or out of an image.
It would be something like the following
picImage.Image = New Bitmap("c:\test.tif")
or to zoom picImage.zoom = 50
|
|
|
|
|
Please don't make your project rely on office, merely to show a bitmap.
Handle your Paint event. In there, draw the bitmap, using the Graphics object in the event args, and the DrawImage method. The Graphics object also has a ScaleTransform method, you can call this to change the zoom of your bitmap, or you can manipulate the parameters to DrawImage to do it.
It's pretty straightforward.

Thanks everyone for all their help.
I have done the following code and it works. Hopefully this will be useful to others. All you need on your form is a Panel, Picture Box (this goes inside panel) and a button
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
picImage.Image = New Bitmap("c:\test.tif")
' Get the source bitmap.
Dim bmSource As New Bitmap(picImage.Image)
' Make a bitmap for the result.
Dim bmDestination As New Bitmap(
CInt(bmSource .Width / 8), _
CInt(bmSource .Height / 8))
' Make a Graphics object
Dim grDest As Graphics = Graphics.FromImage(bmDestination)
' Copy the source image into the destination bitmap.
grDest.DrawImage(bmSource, 0, 0, _
bmDestination.Width + 1, _
bmDestination.Height + 1)
' Display the result.
picDest.Image = bmDestination
End Sub

Hi,
I'm writing a small app that will retrieve the assembly version number of all assemblies in a particular folder.
To do this I'm loading each assembly into its own app domain, getting the info I need and then unloading the app domain. But this still leaves the assemblies locked - they are only unlocked when I exit the application. How can I get around this?
To be able to load each assembly in its own app domain my own application has to be running from the same location as the assembly. Is there any way around this?
The code I use is below:
<code>
Private Sub ListProjects(ByVal root As String)
Dim baseDirectory As New DirectoryInfo(root)
Dim assemblies As FileInfo() = baseDirectory.GetFiles("*.dll")
For Each fi As FileInfo In assemblies
Dim fileVersion As String = String.Empty
Dim assemblyVersion As String = String.Empty
Dim name As String = fi.Name
Dim path As String = fi.FullName
Dim appDomainName As String = name.Substring(0, name.LastIndexOf("."c))
If name.ToLower.EndsWith("vshost.exe") Then Continue For
Dim ad As System.AppDomain
Dim assem As System.Reflection.Assembly
ad = System.AppDomain.CreateDomain(appDomainName)
assem = ad.Load(System.Reflection.AssemblyName.GetAssemblyName(path))
fileVersion = GetFileVersion(assem)
assemblyVersion = GetAssemblyVersion(assem)
Debug.Print("App Domain = " & ad.FriendlyName)
Debug.Print("Assembly name = " & name
Debug.Print("File Version = " & fileVersion
Debug.Print("Assembly Version = " & assemblyVersion
Debug.Print("==========================================")
AppDomain.Unload(ad)
Next
End Sub
</code>
Thanks,

And those would be??? Each cell can only hold a single value or object, so you'll have to provide a bit more detail as to what your talking about.

VS 2005 / Framework 2.0 allows you to store settings as User Settings and Application Settings replacing the older style App.Config in Framework 1.0. You can now publish your application and any updates can be forced to the end-user. Unfortunately when you publish the user settings that the client is able to change with my form and save, get wiped out to default. Also, if I setup Isolated Storage for the settings to be stored into, when I re-publish once the app has been in production for a while, it resets everything to default.
Am I missing something?  Microsoft gives you the capabilities to store a users own settings for their app, but boom when you republish, the settings get reset to default.
Any insight is appreciated..

I had this same problem with an issue. I decided it was easier just to store my values (I only had a few) in the registry by user name.
Hope this helps.

In VB2005, how can I dinamically create a Timer inside a class without using the control. I suppose that I have to use the System.Timers.Timer class but I don't know how to handle the Elapsed event.
Thanks in advance,

Do you mean something like this?
Private Sub TimerForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Timer1 As New System.Timers.Timer()
AddHandler Timer1.Elapsed, AddressOf TimerEvent
End Sub
Private Shared Sub TimerEvent(source As Object, e As Timers.ElapsedEventArgs)
MsgBox("Hello World!")
End Sub
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.
