Sounds nice but I am having trouble getting my parameterised query to work using MySQL. However, the code that I am currently using to insert is working fine now. Also, I found out why the empty rows are being inserted into the db. The file that I am cleaning is being cleaned and making the file double spaced. I could use a helping hand with this issue. Here is the code that I used to clean the file:
'Read file line by line
Dim file_name As String = "c:\Scanning files\lsprint_MO.txt"
Dim Temp_file As String = "c:\Scanning files\lsprint_MO_temp.txt"
Dim textline As String
If System.IO.File.Exists(file_name) = True Then
Dim objReader As New System.IO.StreamReader(file_name)
Do While objReader.Peek() <> "-1"
textline = String.Concat(objReader.ReadLine(), ControlChars.NewLine)
If textline.IndexOf("xxxxxxx") = 17 Then
Console.WriteLine(textline)
WriteFile(Temp_file, textline)
End If
Loop
objReader.Close()
My.Computer.FileSystem.DeleteFile(file_name)
End If
Any ideas would help!

It's called Validation and you're not doing anything to verify that what you're reading is valid. You're just assuming that what you have in your variables is good and that's why your database is comming up with zeros.
You're going about reading a text file the hard way.
Dim sourceFilename As String = "C:\Scanning files\lsprint_MO.txt"
Dim tempFilename As String = "C:\Scanning files\lsprint_MO_temp.txt"
Dim textline As String
If System.Io.File.Exists(sourceFilename) Then
Try
Dim sr As New StreamReader(sourceFilename)
Do
textline = sr.ReadLine()
' Why are you using String.Concat?? Your building a line and adding
' blank lines to the textline string. Why??
' Parse your line here and make sure that the values you got are VALID!
' If not, jump to some other method to report or log the problem.
' If we get here, the data looks good. Add it to the database.
' Call your database code here and pass the "cleaned" values to it.
Loop Until textline Is Nothing
Catch ex As Exception
' Something happened during the file read or database call.
' Log the error or report it somehow and forget the rest of the file.
Finally
If Not sr Is Nothing Then
sr.Close()
End If
End Try
It would also help to see a sample of the file you're trying to read and parse.

Sir,
I am converting a ActiveX(DSO Framer)control into .Net assembly.
1. I was able to import it as assembly using "Tlbimp" utility,
2. I could able to convert the content in to Intermediate Language form by using utility "Ildasm" utility. But
3. When I tried to edit the content for verification by using the utility "Ilasm" its giving error as below
Errors /* No entry point declared for executable
Could not create output file, error code=0x80004005
***** FAILURE *****
Please give me what to do now. Please.
and

Not possible unless you write all the code yourself.
indian143 wrote: 1. I was able to import it as assembly using "Tlbimp" utility,
No, you were able to have TlbImp create a wrapper assembly around your ActiveX component. This means that you still have to install both the DSOFramer control AND the .NET wrapper class you just made on the clients machine. So, you didn't take away the installation requirements, you actually added to it.
indian143 wrote: 2. I could able to convert the content in to Intermediate Language form by using utility "Ildasm" utility. But
Not possible since this control wasn't written in any managed language. You can use this tool to see the IL code in the wrapper, not the control it wraps.
indian143 wrote: 3. When I tried to edit the content for verification by using the utility "Ilasm" its giving error as below
What you're trying to do is not possible. We've already told you half a dozen times, you either have to write a replacement control from scratch or find a replacement control that offers the functionality you want. You can NOT convert this control to a .NET assembly, you can only wrap it in one.

I had this problem too, although it happened for me both when I ran the project through vb and when I ran the exe. I solved it like this:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
'Hide the form while splash screen is visible<br />
Me.Hide()<br />
<br />
'Insert your form loading code...<br />
<br />
'Reveal the form when loading is complete<br />
Me.Show()<br />
End Sub
Hope this helps.

Thanks my friend , but the problem wasn't solved ,
Now for a period I will cancel splash screen until I can find any thing else
jooooo

since you are using vb.net..you could set the properties to topmost = true
or in the form load...
Me.TopMost = True where me is the name of the form..hope this help for you..

Hi Emmanuel,
First off it is best to only bother with VB.NET (VB6 = old). The best tool is Microsoft's .NET Studio. If you can obtain it, it contains its own documentation with step-by-step walkthroughs for all kinds of operations. With these walkthroughs you can create simple projects that you can then experiment with and expand.

My advice is free, and you may get what you paid for.

Hi,
I would like to know how to get the item being selected by the user from the popup menu which occurs when the user right clicks anywhere in the desktop or for eg if a slide show is running then how to get which menu item is been selected by the user from the menu which appears when he right clicks?
Plzzzzzz help me in this....;)

The actual control that you are talking about is not called a popup menu, it is called a ContextMenuStrip control. It works just like a MenuStrip control. Each item on the ContextMenuStrip is a ToolStripMenuItem and you can program the click event for each one. You should be able to find more information or help on the subject if you actually search for "ContextMenu".
Hope this helps.

I have a large project (800 000 lines) in VB6 which I am attemting to convert to .NET. This project does a considerable amount of asynchronous processing, requiring the called activeX module to call back to the calling activeX upon completion of a task, or to signal that an event has taken place.
This was easy in VB6: simply pass the activeX object to the called program as an initial parameter. Subsequent return calls are made to this object.
Surely there must be a simple way to achieve this same goal in .NET? I have spent days experimenting without success.
I cannot believe that Microsoft have taken a simple, elegant and practical language like VB6 and turned into an exercise in obscure, abstract computer science!
