Can't create a click event in a tool stip item

[wgfjr]

I have a tool strip menu item who's collection is filled from a subroutine that loads all available com ports on the computer at for load.

I know how to generate a click event for menu items that are filled, but not if they haven't been filled already.

I guess it doesn't need to be a click event. It just needs to do something that I can get the .text and use it to configure a serial port.


Any ideas?

Ya know that part of the method being called from an event where it says:

(object sender, eventargs e)

The sender would be the menu choice that called the event. Get the text from the sender. sender.text

I don't know what the program will name them. The list isn't populated until runtime.

I tried to fake it by creating option with names that might be there, but the compiler yelled at me. also it wouldn't account for all the posible com port options.


Now the list does fill with valid com port names. All I want to do is asign the .text to the serialport1.portname

[tlhintoq]

I don't understand. Com ports are named "COM1", "COM2", "COM87" etc. Besides... you don't really need to know the name of the com port in advance, do you? When you open a com port you give the serialport control the name of the com port. Just feed it the name that is selected by the user.

Maybe some of the pertinent code would help.

I'mtrying to figure out how to get the name of the port. The user can select the port from the toolstrip menu. But I am having trouble capturing the event of when they click on it. I know hao to do it from a combo box. every time the .text field is updated I would just capture the data then.

Here I can't seem to use the same method. It's like I need to know the name of the tool menu strip item in order to pull it's .text property (COM port). But none of them exist until run time.

I have no real code for this section. The rest are just click events that I asign values for baud rates, data bits, etc. All of which are known items. I can deal with them.

As soon as I can I will post my existing code.

Hi,

I think this might be what you're looking for. At the moment you create a ToolStripMenuItem, you need to assign an AddHandler. Perhaps this piece of code might help.

'assuming the toolstripmenu has been created with ToolStrip1 as name
Dim a As Integer
Dim NumberOfComPorts As Integer
 
For a = 0 to NumberOfComPorts
    Dim TempToolStripItem As New ToolStripMenuItem
    With TempToolStripItem
      .Name = "COM" & a
      .Text = "COM" & a
    End With
    ToolStrip1.Items.Add(TempToolStripItem)
    'Create the reference to the click-event, called a handler
    AddHandler ToolStrip1.Items(TempToolStripItem).Click, AddressOf ToolStripMenuItem_Click
Next
 
Private Sub ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Dim NewToolStripMenuItem As ToolStripMenuItem = sender
        Dim NewToolStripMenuItemName As String = NewToolStripMenuItem.Name
        Dim NewToolStripMenuItemText as String = NewToolStripMenuItem.Text
End Sub

I hope it's helpful!
