What you call the object is up to you, because you must write the component that will do this search. There is no object that will do it for you.

Hmm actually i mean wat is the component I need to declare like CreateObject("Shell.Application") is the component Shell or others? I had tried Shell but Shell only can get the title bar from IE or folders windows, else it does not read. However, I have to get the title bar from an open application window. Any idea what is the component to use?
Thanx a great deal.

Notepad just edits text files. Are you talking about opening and reading the file, or are you trying to the the contents of the Notepad window?
Notepad doesn't put any locks on the files it opens, so use standard file methods to open and read it.
Reading the Notepad window will be much more difficult to do in VB because now your trying to read the memory of another process, something that is "mostly" forbidden in Windows.

Hello !!
I'm very new to VB programming and I would like to call a function I've written inside a dll. The function must receive a pointer to a Byte Array. So I suppose I have to declare something like that in VB:
Public Declare Function MyFunc Lib "MyDll.dll" (ByRef Data As Byte)
Ok, that's work fine but later when I want to call the function and send parameter, this doesn't work:
Dim arrData(0 To 1) As Byte<br />
arrData(0) = SomeData<br />
MyFunc(arrData)<br />
But this doesn't work: comple error ByRef argument type mismatch.
And I tried other things but nothing works... Sometimes the program compile and call the function but if I debug my dll, I can see that the data that is sent is not correct....
Any idea of how I can do that ?
Thanks

hi all,
how to show color palette in vb.net not color dialogbox
Waiting for u r replies.

If you don't want to use the Color Dialog or 3rd party controls, you're going to have to custom draw this, possibly using GDI+. How this is done will depend heavily on how you want it to look. I suggest doing to research on Code Project and/or other sites, searching for "Color Picker".

will this feature be part of Visual Basic 8.0? i read of many new featuren but this was not on the list (it was shortened by the author)
i think it's a discrimination of VB programers against C# programers ^^
there are 2 ways for C# Code:
- in-code comments like this XML-tags
or
- a link in the project-file to an external xml-documentation-file
but both failed with the VB Compiler
- syntax error
- the xml-files was not included

Yes (see How to: Create XML Documentation for Visual Basic[^]).

No, it's not. They're simply two different products and the teams making them prioritize features differently.

oh thanks,
I read this way of documentation in a C# Project with that style:
///<Summary>
///the text
///</Summary>
and I tryed this also in VB .NET with ' but not '''
...my mistake ...

hi,
i'm from germany and so i dont know the right translation für
"Verweise" into englich (Buttontext of the english Visual Studio version)
- link
- refernez
- imports
- ...
i hope you know what i mean...
why is it impossible to set an "link" to an windows application (i.e. .exe-Project) to use this namespace?
in COM it was possible to refer to an ActiveX-EXE-Server, an exe-Project which provides several classes ...

Well, I also read your question about remoting (I didn't answer because I don't have any experience with it yet) and after that question of yours I guess you're mixing up some concepts. More precisely I think you should make yourself clear what the differences between Win32, COM and .NET are and how interoperability between these three technologies is achieved. Just have a look at these links to get started:
Windows API Start Page[^]
The Component Object Model: A Technical Overview[^]
What Is .NET?[^]
Introduction to COM Interop[^]
Best regards
Dennis
P.S. I'm from Germany myself so feel free to contact me in German. However if you want to do so I suggest you write to me via e-mail because I think it's impolite to use a foreign language in an english speaking newsgroup.

Hi All,
I've created an aspx page with a few textboxes and a button to send. Behind this button is the code:
Dim mailt As New MailMessage()
mailt.To = "myemail@gmail.com"
mailt.From = "testemail@hotmail.com"
mailt.Subject = "Subject"
mailt.Body = "Testbody"
mailt.BodyFormat = MailFormat.Html
System.Web.Mail.SmtpMail.SmtpServer = "smtp.mydomain.be"
System.Web.Mail.SmtpMail.Send(mailt)
The problem is this works but takes very long and I must delete the <..... INHERITS="mydomain.testmail"%>
otherwise I got the message error 503 the mailserver needs authorization.
What can I do or do I wrong?
Thx!

here's te deal i have a form that has 2 buttons on it.
i need to call the buttons click event from a different form in order to run the event i would just put the code into the form_load event but the form has a duel purpose so i can't do this.
so in VB.NET, how do we call the click event form a different form
i have tried the performclick() and this doesn't seem to work .
here is a sample of code
<br />
Private Sub EnterBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles EnterBtn.Click<br />
' these next 2 lines remove the unwanted characters from the<br />
' beginning and end of the card value in this case, the card <br />
' values are 4 numbers delimited with a ; at the beginning<br />
' and a ? at the end<br />
txtPassID.Text = txtPassID.Text.Remove(0, 1)<br />
txtPassID.Text = txtPassID.Text.Remove(4, 1)<br />
'**********************************************************************<br />
CIfrm.txtPassIdSearch.Text = txtPassID.Text<br />
CIfrm.SearchIDBtn.PerformClick()<-- not performing as it should <br />
CIfrm.ShowDialog(Me)<br />
Me.Close()<br />
End Sub<br />
i have to different searches being performed depending on what form the user uses.
any help would be great
Help is great only if you ask correctly

You need to make the event handler method for the button click on Form2 public and within it check what control it is handling:
Public Sub Search(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click<br />
<br />
If sender.GetType Is GetType(Form1) Then<br />
MsgBox("Button Called By Form 1")<br />
ElseIf sender Is GetType(Button) Then<br />
MsgBox("Button Called By Button")<br />
End If<br />
<br />
End Sub
Then from the other form you can call this method in the load handler:
<br />
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
<br />
Dim form1Instance As New Form1 'Only if you don't have another instance<br />
form1Instance.Search(sender, e)<br />
<br />
End Sub<br />
Hope this helps, although maybe you want to rethink your design a bit though and have a another class that performs the search that each form could access independently:
<br />
Public Class Search<br />
<br />
Public Shared Sub DoSearch(ByVal sender As Object, ByVal e As EventArgs)<br />
<br />
If sender.GetType Is GetType(Form1) Then<br />
MsgBox("Button Called By Form 1")<br />
ElseIf sender Is GetType(Button) Then<br />
MsgBox("Button Called By Button")<br />
End If<br />
<br />
End Sub<br />
<br />
End Class<br />
You could then call this from anywhere without even creating an instance of the Search class using:
<br />
Public Sub Search(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click<br />
<br />
Search.DoSearch(sender, e)<br />
<br />
End Sub<br />
Cheers

Hi All,
I have a bit of an issue. My issue is, I have several Oracle tables which have the same type of data, however these tables are under different schema users. Now I would normally do this in Oracle and set grants privs on those objects, however I can't do that. What I have to do is combine those tables using vb.net. Now for my question how do I that?
Do I set up the datatables and then put those datatables into a dataset? How do I this programmatically??
Any help would be appreciate it.
Thanks,

hey,
i am trying to assign values to my combo box items. I thought that as you add an item to a combo box you could also just add a value.
I am having great trouble doing this.
i have a datatable with a 'name' and 'id' column. i want the combo box to display the name but when it is selected to get the id.
i currently have the following code
cmboConnections.DisplayMember = "name"
For i = 0 To connectionTable.Rows.Count - 1
If Not connectionTable.Rows(i).Item("name") Is Nothing Then
cmboConnections.Items.Add(connectionTable.Rows(i).Item("name"))
cmboConnections.ValueMember = connectionTable.Rows(i).Item("ID")
End If
Next
I am unable to find any property wher you can just combobox.SelectedItem.Value or combobox.Item(X).Value. Is there any way to set a value of a item in a combo box?
Thanks for your help
Chris

I am now using a datatable
cmboConnections.DataSource = connectionTable
cmboConnections.DisplayMember = "name"
cmboConnections.ValueMember = "ID"
Which populates my combobox but i have no way of retrieving the Valuemember from the selectedIndexchanged event.
Does anyone no how to get the ValueMember from a selected item?
I have tried using the SelectedIndexChanged Event but the combobox.SelectedValue is a datarow and cannot be converted to string apparently?
Any suggestions this is quite urgent
Thanks for your help
