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".

hi,

in some C#-Project a some comments included to describe the code better
the commands are
<Summary>
<Param>
<Return>
and so on

my question, is it posible to use it in VB .NET too?

There is no built in functionality to do this. But I believe there are third party add-ons that will allow it.

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.

Can't set a link to a exe Project

26-Nov-04 8:34

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:

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!

call the click event of a button

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 Smile | :)

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

Concatenating multiple datatables

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, Laugh | :laugh:

combo box item values - Possible?

cwayman25-Nov-04 2:21

25-Nov-04 2:21

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

Loading bulky XML into dataset

There are lots of articles around the 'Net that describe this. You can search CodepOroject Articles for "bootstrap" and find a few projects that deal with this. You can also try searching GotDotNet.com for the same thing.

The problem your having is your using XML as a large database, which it is extremely poor at. Your data really belongs in an actual database, like SQL Server, and not a very large text file.

SCENARIO (New project started using ASP.net 2.0):

At this point, I am simply trying to open a connection to a datastore.

Application settings: <default web="" site="">\AAC

Physical path of database file:
C:\Inetpub\wwwroot\www\AAC\data\dbStore.mdb

Script running from file in /gallery directory
C:\Inetpub\wwwroot\www\AAC\gallery\aStore.aspx

...
Dim mPath As String = Server.MapPath("\data\dbStore.mdb")
...

returns error:
'C:\Inetpub\wwwroot\data\dbStore.mdb' is a physical path, but a virtual path was expected.

What am I doing wrong? Am I missing some configuration in the web.config file?
I never had that sort of problem with ASP.net 1.1

Any help appreciated,
