If you want a different answer, try telling us what it is you're trying to do.

I'd suggest that you forget about it for now. I still have no idea what you want. You want to write a control. I have no idea what it does, so all I can tell you is to derive from a base control class. It looks to me like you're a few steps short of knowing enough about software development to be thinking of writing anything.

I would like to know is there a way to have a script that will change the order of registry data?
What I need to have is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\Bind
Which is REG_EXPAND_SZ type
I need to have \Device\NdisWanIp entry move to the top without modifying any of the other unique data lines.
Is this possible with WMI or any other type of scripting.

|
|
|
|
It's a REG_MULTI_SZ, not an expand type.
You'll have to read the string value that's stored into an array of strings, then reorder the array using standard array methods, and write then value back out. The WMI StdRegProv Provider will work with Multi_Sz values.

Trying to see if anyone can convert the code from Robert Rohde from C# into VB.net. This is an awsome kluge for the missing default view property in a file dialog box.
http://www.codeproject.com/cs/miscctrl/FileDialogExtender.asp?msg=1042669#xx1042669xx
Im really weak when it comes to this kind of programming. Looks like it should be fairly easy, and MANY people are looking for this it seems. Anyone feel like taking the adventure? I would love to see this thing work for me as a function or something.
Heck.. I'd settle for someone to walk me through making and calling the .dll too 
Kudos to Robert Rohde!

You found the easy way to do it. Try converting the code yourself. If you get stuck, search the web for C#/VB.NET translators. They're out there and their as easy to use as copying and psting sections of code, like a subroutine from one language to another.

I keep running into errors due to the preprocessor... namespace vs. class and whatnot.

I did not extensively test or refine this code. It works on my machine - Win2K NET 2002.
There is minimal error handling. I mostly just translated the original C# code referenced into VB.
This should get you started...

 Does anyone know of a way to add a suffix to a vb variable based on another variables content?
I have a variable that is global named "LineNumber" and would like to append it to the end of a variable named "Line" in the Dim.
Exaple:
Private LineNumber as integer
private sub AddNumber()
dim Itm as new combobox
end sub
I would like to append the contents of "LineNumber" to the "Itm" name on the Dim statement.
regards

??? WHAT ??? 
Are you asking this:
Private LineNumber As Integer = 506
Private Sub AddNumber()
Dim Itm506 As New ComboBox
End Sub
You can't.
What are you really trying to do with this?

I want to use the contents of LineNumber as the last part of Itm name.... If the contents is 506 then I want my dim statement to say "Dim Itm506 as combobox"

First, you can't do that. Second, there is no reason to do this.
You really don't even need to keep an array of ComboBox controls. You can keep track of how many lines of controls your putting into the Panel's Controls collection. When you put a row of controls into the collection, you can set the ComboBox's Tag property to the line number it's on. You can then easily go through the Controls collection, looking for the control type and looking at each controls Tag property, matching it against the line number you need to delete.

Dave,
How do I tell which control to delete if they all have the same variable names? Below is my code:
Private Sub cmdAddLine_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdAddLine.Click, cmdDeleteLine.Click
Panel1.AutoScrollPosition = New System.Drawing.Point(0, 0)
cbItem = New ComboBox
cbItem.BackColor = Color.Wheat
cbItem.Name = "cbitem" & LineNumber
cbItem.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
cbItem.Size = New System.Drawing.Size(196, 19)
cbItem.Location = New System.Drawing.Point(0, LineNumber)
cbItem.Items.Add("A)
cbItem.Items.Add("B")
cbDiscount = New ComboBox
cbDiscount.BackColor = Color.Wheat
cbDiscount.Name = "cbDiscount" & LineNumber
cbDiscount.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
cbDiscount.Size = New System.Drawing.Size(48, 19)
cbDiscount.Location = New System.Drawing.Point(cbItem.Size.Width + cbItem.Location.X, LineNumber)
cbDiscount.Items.Add("05% ")
cbDiscount.Items.Add("10% ")
cbDiscount.Items.Add("15% ")
cbDiscount.Items.Add("20% ")
cbDiscount.Items.Add("25% ")
cbDiscount.Items.Add("30% ")
cbDiscount.Items.Add("35% ")
cbDiscount.Items.Add("40% ")
cbDiscount.Items.Add("45% ")
cbDiscount.Items.Add("50% ")
txtAmount = New TextBox
txtAmount.BackColor = Color.Wheat
txtAmount.Name = "txtAmount" & LineNumber
txtAmount.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
txtAmount.BorderStyle = BorderStyle.Fixed3D
txtAmount.Size = New System.Drawing.Size(56, 19)
txtAmount.Location = New System.Drawing.Point(cbDiscount.Size.Width + cbDiscount.Location.X, LineNumber)
txtQuantity = New TextBox
txtQuantity.BackColor = Color.Wheat
txtQuantity.Name = "txtQuantity" & LineNumber
txtQuantity.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
txtQuantity.BorderStyle = BorderStyle.Fixed3D
txtQuantity.Size = New System.Drawing.Size(56, 19)
txtQuantity.Location = New System.Drawing.Point(txtAmount.Size.Width + txtAmount.Location.X, LineNumber)
txtSubTotal = New TextBox
txtSubTotal.BackColor = Color.Wheat
txtSubTotal.Name = "txtSubTotal" & LineNumber
txtSubTotal.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
txtSubTotal.BorderStyle = BorderStyle.Fixed3D
txtSubTotal.Size = New System.Drawing.Size(56, 19)
txtSubTotal.Location = New System.Drawing.Point(txtQuantity.Size.Width + txtQuantity.Location.X, LineNumber)
txtTax = New TextBox
txtTax.BackColor = Color.Wheat
txtTax.Name = "txtTax" & LineNumber
txtTax.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
txtTax.BorderStyle = BorderStyle.Fixed3D
txtTax.Size = New System.Drawing.Size(56, 19)
txtTax.Location = New System.Drawing.Point(txtSubTotal.Size.Width + txtSubTotal.Location.X, LineNumber)
txtTotal = New TextBox
txtTotal.BackColor = Color.Wheat
txtTotal.Name = "txtTotal" & LineNumber
txtTotal.Font = New System.Drawing.Font("Comic Sans MS", 9, FontStyle.Regular)
txtTotal.BorderStyle = BorderStyle.Fixed3D
txtTotal.Size = New System.Drawing.Size(55, 19)
txtTotal.Location = New System.Drawing.Point(txtTax.Size.Width + txtTax.Location.X, LineNumber)
Panel1.Controls.AddRange(New Control() {cbItem, cbDiscount, txtAmount, txtQuantity, txtSubTotal, txtTax, txtTotal})
cbItem.Focus()
LineNumber += 25
Console.WriteLine(cbItem.Name.ToString & " " & cbDiscount.Name.ToString & " " & txtAmount.Name.ToString & " " & txtQuantity.Name.ToString & " " & txtSubTotal.Name.ToString & " " & txtTax.Name.ToString & " " & txtTotal.Name.ToString)
end sub

You're so hooked on variable names... forget about them! They're meaningless in your case.
Think about it... How do programmers create thousands of objects with only a single set of variables? They use arrays, collections, hashes, ...
A single variable, in your case Panel.Controls, can hold a couple thousand controls. All you need is a way to identify the individual controls, not by a variable reference, but by an identifying number, the Tag property of each control.

I understand all of what your saying. My question remains the same. How do I detemine which control to delete when the user clicks the delete a line button?

Click a Delete Line button.............

I take it each line will have one of these buttons next to it? In that case, the button gets the same Tag value as the other controls on the line. When the user clicks on the Delete button, the button handling code checks the Tag property of the button that fired the event, then uses that Tag property to search through the Panel's Controls collection and find the controls that match that Tag ID.

Why not use an array or collection of combo-boxes, assuming that you are trying to keep track of multiple controls.
