i wonder how to show an image by giving the location of the image and show in the picturebox???
like Path.GetDirectoryName(Application.ExecutablePath) & "\image\image1.jpg"

You have to import System.IO namespace before declare the class. Like
Imports System.IO
Public Class Form1<br />
.<br />
.<br />
.<br />
.
Then,
PictureBox1.Image = Image.FromFile(Path.GetDirectoryName(Application.ExecutablePath) & "\image\image1.jpg")

I am taking my first programming class in VB. I am working on an assignment that involves calculating a selling price with the cost sold of a vehicle and the results is suppose to show the total commission earned from the sell, total number of vehicles sold and the average commission and also a counter. Everything on my form works as designed except for my calculate feature.
If I can just get the calculation between the selling price and the cost sold to work then I think I can eventually figure out the rest of the coding. Can someone please point me in the right direction on how to code this issue?
Thanks

It means that you have not initialized an object correctly and its reference variable is still NULL.
Use the call stack trace provided in the message to pinpoint the code in error.

I have the following function
Public Function AddSheetCopy(CopyName As String, NewName As String)
For Each xlSheet In xlApp.worksheets
If xlSheet.Name = NewName Then
MsgBox ("sheet exists")
Exit Function
End If
Next xlSheet
MsgBox (xlApp.worksheets(1).Name)
xlApp.worksheets(CopyName).Copy after:=xlApp.worksheets(xlApp.worksheets.Count)
xlApp.activesheet.Name = NewName
Set xlSheet = xlApp.activesheet
End Function
It's pretty simple, I just want to make a copy of a worksheet, and give it a new name. Problem is it's not working exactly as it should. You will notice in the above code there is a message box to display the name of the first sheet, when running the code as above it works, but if you comment out that message box, it makes a copy of the current active worksheet.
Obviously I don't want to be plagued with this message box, but I am unable to make the function work without it.
Any ideas?

Hi All
I have a small problem that I hope someone will be able to help with...
I have a windows app that does a lookup in a DB table to find words that match in its glossary.
If the word finds a match in the glossary table, I want to have that word highlited (With a Clickable Link) in a RichTextBox so that the user can click on the link and another window will open up and display the glossary entry.
I don't have a problem doing the lookup. It's the inserting a link into the RichtextBox in the middle of plain text, for the word that has a glossary entry. I cant use the DetectUrls property as that is only for web links.
If you know how to do this, Thank you.
Otherwise if you know how to do this with a different control, please let me know
Thanks

objConn.Open()
dr = cmd.ExecuteReader
'Dim img As Byte() = CType(cmd.ExecuteScalar(), Byte())
If dr.Read = True Then
Response.BinaryWrite(dr("bits"))
End If
Response.ContentType = "image/jpeg"

Hello,
what I try to create is a .Net user control which can be used in VB6. Until now I wrote a class library with a .Net form and a COM class. This library I can use in VB6 without problems. But the creation of a user control seems to be a little bit more difficult. Has anybody done this before successful? Does anybody know or have a tutorial or an example for this?
