Hi All,
I am binding a DataGrid to an ArrayList, but in the Grid, it does not show the append row, the one with the asterisk, like it does when binding to a Table or a DataView.
Is there any way to have the grid show the append row when using an ArrayList or Array?
The approach I am exploring right now, is using a class that inherits ArrayList, but cannot figure out which properties it should have, to enable the desired behavior.
Anyone have an idea about this?
Many thanks!

Hello,
I created the class "document":
Public Class Document
Private Shared _title As String
Public Property Title() As String
Get
Return _title
End Get
Set(ByVal value As String)
If _title = value Then
Return
End If
_title = value
End Set
End Property
End Class
To set the property value I am using:
Dim MyDocument As New Document
MyDocument.Title = "My book title"
I need to be able to create "second level" properties. An example:
MyDocument.Author.Name = "Author Name"
Instead of having
MyDocument.AuthorName = "Author Name"
I inserted the class "Author", with property "Name" inside Class Document.
It is not working. Could someone explain me how to create it?
Thank You,
Miguel

Don't do that. Put the author class in a file of its own. There are very few good reasons to create an inner class and I doubt this is one of them.

Define "it is not working"! What doesn't it do?

Are you sure _title has to be shared (and Title not)?

It sounds to me like you inserted a class definition, instead of an instance of a class. If you have a class called Author, then you can create a property of type Author, also called Author ( or name it whatever you want ) and it will work as you are hoping.

Hello!
I think something is new in visual studio 2005. Here is the scenerio:
I have a tabcontrol with two tab pages. I have placed one label in 1st tab page and set its visibility to true. When I shift to 2nd tab page the label's visibility has treated as invisible by the compiler at run time.
Is that true? if it is not how could I reach the visible attribute's value while I perform a task in the second tab page rather than defining the following statement
if label1.visible = true then
because it is not working out even though the label1 in visible in 1st tab page.
If you enlight me about it, I would really appreciate it...

Ummm...No, it isn't. It's Visible property is still True, the thign is you changed the page that the control is sitting on! It's just like pages in a book. If you change the selected tab, you turn the page. Stuff that's on the previous page is no longer visible.
You're explanation of what you want to do needs more clarification. I can't figure why you're trying to get the Visible property of your label.

I thought the same as you do Dave but it is not working that way. The label1 is placed on 1st tab page and itss state is visible. However, when i shift from next tab page at runtime (while the code is checking its visibility) it says now the label's state is invisible. I tested this with a message box and I got the state status (Invisible) while I was on the 2nd tab page. I am not sure if it is a bug in the Visual Studio 2005.
But thank you for your help. In the meanwhile, do you know where I can get a sample code for wrting WAB (Windows Address Book) in vb.net?

Damn! Screw up on my part. No, the Visible property reflects the actual state of the control. If some other window obscures the entire control in question, it's Visible property returns False, well, because it's not visible anymore. It's functionality is by design, it's not a bug.
As for the Address Book, I don't know of any example code in VB.NET. But, the documentation for the WAB API is here[^].

Hey folks. I'm faily new to VB2005 and I was wondering if theres a way to have a second form display in the same window as the first (root) form appears
I know you can display a second form in a seperate window by using
my.forms.form2.showDialog()
Thats OK but I would like to have, if possible, the form show in the window that is already open.
any help would be appreciated
Thanks

Well, if you'll notice, the Form class derives from Control. Since all the controls you see on the form derive from, obviously, Control, Form should be able to be used just like a control. You can't make it appear using ShowDialog, but you can treat it just like any other control.
See this[^] little article on MSDN for more information.

Does anybody know how to correctly use the GetUserObjectInformation in VB.Net. I seem to have many problems trying to get it to work. Here is what I am basically trying to do. I want to get the current desktop name. So in order to do so I have to call GetThreadDesktop(GetCurrentThreadId()). Which would go into the handle part of the GetUserObjectInformation call. But for some reason with everything filled in I get an error 0. I have seen this done many times in C++ and C# but have not found any reference in VB.Net.
Thanks,
Jason

Is your API declare like this?:
Private Declare Function GetSystemMenu Lib "user32" _<br />
(ByVal hWnd As Long, _<br />
ByVal bRevert As Long) As Long
Eric Dahlvang-Programmer

|
|
|
Ah! The declare had hwnd as an integer. I used Long like you said and it works great now!
thanks,
sb

|

|

The correct declaration should be:
Private Declare Function GetSystemMenu Lib "user32" _
(ByVal hWnd As IntPtr, ByVal bRevert As Integer) As IntPtr
Handles should always be declared IntPtrs because, just like handles, they're going to be the width of the processor, 32-bit on 32-bit procs and 64-bits wide on 64-bit procs.
The declaration you used, using Long, is a VB6 declaration. In VB6, Long are 32-bit signed integers. In VB.NET, they're 64-bit signed integers. The two representations are NOT compatible with each other!

Hi all,
I'd like to convert an integer to a formatted string that would be filled with "0" until a certain numbers of characters. For example: if the integer value is 10 and the formatted string has to have a length of 6 characters then the final string it would be "000010". Is there any VB6 function to do that?
Thanks in advance,
Marc Soleda.

How can I call a word macro when the document is loaded? (I cannot save it in the document)
I tried with command line param but then it tried to run the macro before the document is loaded. Also saved it in the normal.dot template but I don't have a trigger to call it

In Word help you will find
Run a macro
On the Tools menu, point to Macro, and then click Macros.
In the Macro name box, click the name of the macro you want to run.
If the macro doesn't appear in the list, select a different document, template, or list in the Macros in box.
Click Run.
But I like to add a button to the toolbar and have it run the macro:
Add a button to a toolbar
Show the toolbar you want to add a button to.
On the Tools menu, click Customize, and then click the Commands tab.
In the Categories box, click a category for the command you want the button to perform.
Drag the command or macro you want from the Commands box to the displayed toolbar.
If you don't see the command you want under a particular category, click All Commands in the Categories box.
Tip To quickly add a built-in button to a built-in toolbar, click More Buttons on a docked toolbar, (or click the arrow in the upper-left corner of a floating toolbar), click Add or Remove Buttons and then select the check box next to the button you want to add.

I am afraid this isn't the exact solution. THe thing is, I need to embed this in my application so that it is transparent for the user (from an intranet web application I launch word through havascript to open a dynamic XML from a web service and an XSL to build the document - HTML). I don't want the user to interact at all (needs to be fully automatic) and it needs to be triggered right after the document loads.
