Newbi Question? Help with Menus VB.NET

I have just started working with windows programming in VB.NET with Visual Studio .NET 2003. I have created a mainMenu control on a new form object in the visual creator.

When I go to compile the project my menu doesnt show up. Everything else works just fine though, and my compiler doesn't issue any warnings.

I tried the same project in a C# program and it worked just fine. I would just use C# but I have 8 AppDev study CD's in VB.NET.

I also checked that I left all the defaults alone in the properties for the menu.

This is beyond me why this is happening. I would hate to reinstall my VS.NET and hate more to spend hours trying to figure this out.

Can anyone offer solutions?

How do you mean?

When I created the menu in C# - eveything was done automatically.
Also, under the AppDev tutor it was also created automatically. It seems as though VS.NET might be leaving some inportant info behind.

What do you mean by "include menuItems"?

Creating a component in VB .NET

I am creating a component in VB .NET. The component contains a private ArrayList as in the following example:

Private __ItemList As New ArrayList

I need to create a list of the strings contained in this array and expose them in a property drop-down editor in the Properties window when the component is at design-time.

I understand that I can use a custom Type Converter to display a list of strings in a property drop-down, but the values in my SelectedItemConverter class need to come from the main component that exposes the SelectedItemProperty and maintains the __ItemList array list. I am at a loss as to how to get the list of string values into the converter class so it can return the array of strings when the property is accessed.

Here is how far I have gotten:

Private __ItemList As New ArrayList
Dim __SelectedItem As String

Could someone please convert this to a VB.NET Structure.

1. Change the FormBorderStyle Property of the form to FixedSingle or FixedDialog

2. Override the OnResize method and set the size to be constant.

Free your mind...

In VB.Net form, under Properties of the form, you should set the Maximize button to "FALSE" and there is a Minimumzise & Maximumsize that you need to supply its values in order to disable the maximize button, e.g form size is 300X300, so set Minimumsize to 300 & maximumsize to 300...

Call MDI form procedure in Toolbar

LC Chan30-Mar-04 4:35

30-Mar-04 4:35

Hi All,

I created a Toolbar in the Main form and it has some buttons like Add,Change,Delete. Let's say there are 2 child forms A & B.
In each form, a public procedure - add_record() - is created.

Now, I'd like to call the child form - add_record() in the button.click() event. But it seems the compiler didn't accept it.

Here's the code in tool bar click event.

Protected Sub toolBar_Click(ByVal sender As Object, 
                             ByVal e As oolBarButtonClickEventArgs)

    Select Case tblMain.Buttons.IndexOf(e.Button)
    Case 1
        Call Me.ActiveMdiChild.add_recod()    /* build error occur */
    End Select
End Sub

I think i'm using a wrong approach with Toolbar.

Would anyone give me some advice.

Many thanks, Wilfred Smile | :)

Me.ActiveMdiChild returns an instance of type Form. You're getting the error because Form doesn't contain a method called add_Record.

You need to cast the return value of Me.ActiveMdiChild to the type of the child form the contains that method.

CType(Me.ActiveMdiChild, MyMdiChild).add_Record()

I need to know the name of the object.
did you manually type the procedure below because it lacks the handles toolbar1.click assuming the name of the toolbar is toolbar1.

Protected Sub toolBar_Click(ByVal sender As Object, ByVal e As oolBarButtonclickEventArgs) HANDLES toolbar1.click

find another method for this
Select Case tblMain.Buttons.IndexOf(e.Button)
I'm in an internet cafe so ican't test any code

Lastly
if Add_record() is form, then you need to make an instance of it

dim myform as new AdD_record()<br />
          myform.show<br />

or if it is a procedure in a form
myform.add_record()
will do assuming myform is an open form.

This was a build error, so registered event handlers aren't the problem.

Hi,

Is it possible for a visual basic application to start a vba word macro and have it end without the user noticing? What i want to do is present a user for in visual basic (not VBA) and after they click a button, have a VBA macro run on a document in the background and perform certain operations so the text is different.

also, can you pass the macro value?

thanks

Use the Enabled property of each control. For example:

TextBox1.Enabled = False
MenuItem2.Enabled = False
MenuItem1.Enabled = True

Do I do an if then statement? For example

If MenuItem7.enable = true then
MenuItem5.enable = false
MenuItem6.enable = false
MenuItem10.enable = false
Else If MenuItem5.enable = true then
MenuItem6.enable = false

so on and so on..

Thank you,
