I have a form with a progressbar and a dynamic graphic control
this dynamic control freezes when i run a method in the form.
so i run the method as a new thread in a class.
the problem is that the value of progress bar should depend to a variable in the method.
when i try to assign a value to the progress bar from the thread class I recieve the error message which says: the control is not created within the thread and can not access to its properties.
so how can i access to the value property of the progressbar?

well it's simple!
you have to declare your class with events
so when a value changes you will raise an event.
then...
your form will grab the event and from the form
you will setup the value property of your progress bar.

Look into the BackgroundWorker component. It exposes a standardize method of reporting progress.

I've created a custom control that consists of two textboxes and a treeview. For the control i've added a new property:
Public Property Collection() As List(Of String)<br />
Get<br />
Collection = ItemsList<br />
End Get<br />
Set(ByVal value As List(Of String))<br />
ItemsList = value<br />
End Set<br />
End Property
When I add the control to a form and go to the collections property it offers an ellipses button that opens the 'string collection editor' which is built into Visual studio. This is what I wanted, however, when I click to add a new item to the collection it pops up an error message:
Constructor on type 'System.String' not found.
Can any one offer a solution as to why this is happening. I don't exactly understand what it means by constructer and I have no idea how to implement the constructor to add Strings to the collection.
What I want to do is be able to at least add individual items, then, eventually subitems etc.

I use an API which accesses an information provider via a VPN. The API is declared as follows:
Dim objViewPoint As New DAT32COMLib.TerminalEmulation
The entire application hangs on this statement in .NET if the VPN is not up and running. (Works fine in VB6 where it simply returns an error or times out). The declaration is in an asyncronous process and I have also tried running it in a separate thread.
I would appreciate any suggestions.

I haven't done Office Interop in quite a while. You'd find tons of examples if you just typed "vb.net Word automation" into Google.

You're best source of information for this would be Support from Applied Software[^]. It's very unlikely anyone with any experience with this product is going to see your post.

You'll have to read each record from the SQL table, probably using an SqlCommand and it's ExecuteReader method, and assign the values from each field to the appropriate fields in the OleDbCommand INSERT code to write the data to an Access table.

If your help file is HTML, just put a web browser control on your page, and set the URL to be the path to the file.

i don't know if i completely understand you
BUT if you write your html to any file with
File.WriteAllText("yourfile.ddd", strhtml, System.Text.Encoding.UTF8)
then with a simple webbrowser control you can view it
WebBrowser1.Refresh()
WebBrowser1.Navigate("yourfile.ddd")
hope that helps

You should be able to find everything you need in the System.Net namespace. If not, try Google or MSDN.

*sigh* If you have a video device, then DX is the only way to work with it, unless they offer an SDK. Trying some of the example code on this site will tell you if it works with DX. Didn't I tell you this yesterday ?

Has anyone had experience executing Oracle stored procedures with input & output parameters with VB.net? I've researched online help, articles websites etc. but it does not work. The stored procedure has 5 parameters. The first 3 are Ouput, the 4th is In/Out and the 5th is Input. Here is a sample of the code being used:
Dim cmdAPI As OracleClient.OracleCommand
Dim drAPI As OracleClient.OracleDataReader
'specify API and setup command
pstrSQL = "Oracle_API_test"
cmdAPI = New OracleClient.OracleCommand(pstrSQL, pcnnOra)
cmdAPI.CommandType = CommandType.StoredProcedure
'setup stored procedure parameters
Dim info_ As New OracleClient.OracleParameter("info_", OracleClient.OracleType.VarChar, 256)
Dim objid_ As New OracleClient.OracleParameter("objid_", OracleClient.OracleType.VarChar, 256)
Dim objversion_ As New OracleClient.OracleParameter("objversion_", OracleClient.OracleType.VarChar, 256)
Dim attr_ As New OracleClient.OracleParameter("attr_", OracleClient.OracleType.VarChar, 2000)
Dim action_ As New OracleClient.OracleParameter("action_", OracleClient.OracleType.VarChar, 256)
'set value of parameters
cmdAPI.Parameters.Add(info_)
cmdAPI.Parameters(0).Direction = ParameterDirection.Output
cmdAPI.Parameters.Add(objid_)
cmdAPI.Parameters(1).Direction = ParameterDirection.Output
cmdAPI.Parameters.Add(objversion_)
cmdAPI.Parameters(2).Direction = ParameterDirection.Output
cmdAPI.Parameters.Add(attr_)
cmdAPI.Parameters(3).Direction = ParameterDirection.InputOutput
cmdAPI.Parameters(3).Value = "'PART_NO'||chr(31)||'LG003'||chr(30)||" _
& "'DESCRIPTION'||chr(31)||'Test Part3'||chr(30)||" _
& "'UNIT_CODE'||chr(31)||'EA'||chr(30)||" _
& "'CONDITION_CODE_USAGE'||chr(31)||'Not Allow Condition Code'||chr(30)"
cmdAPI.Parameters.Add(action_)
cmdAPI.Parameters(4).Direction = ParameterDirection.Input
cmdAPI.Parameters(4).Value = "'DO'"
'execute stored procedure
cmdAPI.ExecuteOracleNonQuery(0)
'analyze parameter values
strTmp = IIf(IsDBNull(cmdAPI.Parameters(0).Value), "null", cmdAPI.Parameters(0).Value)
TextBox1.Text = strTmp
strTmp = IIf(IsDBNull(cmdAPI.Parameters(1).Value), "null", cmdAPI.Parameters(1).Value)
TextBox2.Text = strTmp
strTmp = IIf(IsDBNull(cmdAPI.Parameters(2).Value), "null", cmdAPI.Parameters(2).Value)
TextBox3.Text = strTmp
strTmp = IIf(IsDBNull(cmdAPI.Parameters(3).Value), "null", cmdAPI.Parameters(3).Value)
TextBox4.Text = strTmp
strTmp = IIf(IsDBNull(cmdAPI.Parameters(4).Value), "null", cmdAPI.Parameters(4).Value)
TextBox5.Text = strTmp
cmdAPI.Dispose()
pcnnOra.Close()

Is it giving you an error? Are you setting the values in the procedure?
