Hi there are Tow ways to do that but in both ways u should bind each TextBox alone
The First way
TextBox1.DataBindings.Add("Text", DataSetName, "TableName1.ColumnName1")
NumericUpDown1.DataBindings.Add("Value", DataSetName, "TableName1.ColumnName2")
And The 2nd way
Dim NewBind As New Binding("Text", DataSetName, "TableName1.ColumnName3")
TextBox1.DataBindings.Add(NewBind)
where:
"Text" and "Value" is the Property that u want to bind your data to as u see you should pass it as text
DataSetName is your DataSet
"TableName.ColumnName" is Your DataMember
Excuse my English

Hi All,
I have a big VRML model of a building which I divided into small vrml files such as: floor1.wrl, floor2.wrl, roof.wrl, and so on. Basically, I used 'Inline' node to import all of these small vrml files into my mother vrml file called 'building.wrl'.
I am using VB.NET form interface to allow the user to interact with the geometry. It works fine when I load any of the small vrml files (e.g. floor1.wrl) and then I can obtain the name of 3D elements in floor1 so that the user can change their texture. The problem is that when I load the main vrml file 'building.wrl' I am unable to interact with 3D elements inside the 'Inline' node.
So my question: how can I interact with the element/geometry inside an 'Inline' wrl file? Any feedabck or suggestion is very appreciated. I searched the internet for solution but could not find any.
Please please help
Thanks

I have searched everywhere for an answer and I
cannoit find one.
I have a LOT of forms with a standard list "List"
and I call a subroutine in VB6 that accepts the
form and fills the list. Example:
Sub ListFill(byVal aForm as Form)
' get RS from database'
'...
Do while Not Rs.EOF
aForm.List.AddItem Rs("Name")
Rs.MoveNext
Loop
End Sub
Can someone please help me figure out how to
translate this code into .NET?
Aloha and thanks in advance, Tony.

That code uses late binding to access the list in the form. You can only use late binding if you turn of strict checking, which you shouldn't.
There are basically two ways to do this:
1. Create an abstract base class that contains a property that returns a reference to the list. Make the forms inherit the base class, and implement the property.
2. Use the FindControl method to get a reference to the list.
Alternatively, make the method take a reference to the list instead of a reference to the form.
Despite everything, the person most likely to be fooling you next is yourself.

Thank you for the reply.
I tried this code and it still doesn't work.
Public Sub ListBoxFill(ByRef aControl As System.Windows.Forms.Control)
Dim n As Integer
For n = 1 To 5
aControl.additem("Ciao")
Next
End sub
Am I doing something wrong with the reference to the list?
Aloha, Tony.

Sorry, let me clarify. It tells me that
AddItem is not a member of System.Windows.Forms.Control
|
|
|
|
|
Never mind, I am still thinking too much like VB6!
AddItem is a VB6 command, of course it didn't work.
Anyway, your suggestion to pass the control seems
to work. Thank you!
|
|
|
|

Pass the parameter as a ListBox instead of as a Control, otherwise you have to cast it before you can access the specific methods for the ListBox.

Hi, all.
I have one simple question, how to i open a windows form one project in other windows application project ??
I have 2 projects in one solution, and i added a refrence to my main windows application project, so i can see all the forms in other project.
Dim NewForm as windowsapp1.form1NewForm
NewForm= new windowsapp1.form1
NewForm.Show
Is there anyway to bypass this code, and open a form directly without declaring a new form and then open it?
Tnx for your help in advance.

Can you open a form without opening it ? How were you hoping to do that ? You can use Process.Start to start another exe, but that's about it.

The thing is i have one main project.
In that project i want to display Windows Forms form other project.
Since i have 30 forms in that other project i dont want to declare a new form evry time i need to open it, becuse its very time consuming.
So i was just wondering is there any other way to do it ?
not to use;
Dim newForm as mainAPP.form1
newForm = New mainAPP.form1
newForm.show()
use something else to access the form directly if extists....

Like I said, nothing else exists, plainly the way to open a form is to create it. On what basis were you hoping for them to open, I mean, you have to do SOEMTHING, to control when it happens, right ?

I did find a way to do it using system.reflection.
Private Sub OpenFormFromAssembly(ByVal FormName As String)
Dim MyAssembly As Reflection.Assembly = Reflection.Assembly.LoadFile(" Assembly to load ")
Dim MyTypes As Type() = MyAssembly.GetTypes
For Each mType As Type In MyTypes
If mType.BaseType Is GetType(Form) Then
If mType.Name = formName Then
Dim o As Object = Activator.CreateInstance(mType)
Dim f As Form = CType(o, Form)
f.Show()
End If
End If
Next
End Sub
No need to declare a new form evry time you need to open it.
BTW, i will load an assembly if is active in database,if user has right to access it....
Tnx for your help.

Sure - the real question is, why do you want to open every form modelessly ? I mean, what possible use is this ? You app has 30 different forms open, and no way of interacting with any of them. That's the core question I was asking you, why do that ?

Since im realatvly new to Vb.Net, i will ask you why not??
Main advatage is i dont need to declare a new form evry time i need to open it, instead of that i
just call a Windows Form from assambly and open it.
Im planing to have 6 projects in one solution, one project will be my main windows app in wich i will load all of my windows forms and display it to the user.(imagine the time lost if i need to
declare a new Windows Form evry time i need to open it, 6 projects > 70+ Windows Forms)
Your app has 30 different forms open, and no way of interacting with any of them.
How do you mean "no way of interacting with any of them" ??
I have now one main project(wich loks like outlook style app, and is my startup project) and in that project im adding particular form(from any of my projects) to my main panel (using controls.Add method) and displaying it to the user. So i have a good way to interact with the Windows form,
and the controls on it.
So now when you know what im planing to do, if you know/have any better solution, for the way to do it, im open for sugestions.
Tnx in advance.
Nihad.

Because I can't imagine any real world reason to create a bunch of forms that my code cannot interact with again. Nor can I see any reason to have 30 forms on the screen at all.

If you want to create a form, doing it via reflection is a lot more work.
C4ao5 wrote: .(imagine the time lost if i need to

This is BS, sorry. Your app will run slower from using reflection.
C4ao5 wrote: How do you mean "no way of interacting with any of them" ??
Your 30 forms are like 30 different apps all running by themselves. None of them can cause any other form to behave differently.
C4ao5 wrote: So i have a good way to interact with the Windows form,

no. When you create a modeless form and do not store a reference to it, or even when you do, but it's a base Form, not the derived class, you have NO way of interacting with the controls on it in code, outside that form, ever again.

Ok, i understand your point, so what would you sugest when developing a solution with multiple projects ??
What is the best way to do it, if any ??
I would realy like to develop an outlook style app, in wich user can select an app wich he needs
for his/hers daily work....
Rgrds.

Well, in that case, I'd develop a plugin architecture, and define an interface all plugins could expose, so that you can add functionality beyond the base Form class. I'd then have a list of those plugin types, let the user open a plugin via the sort of mechanism you're using now, but to keep those open forms in a list, so you can interact with them via that common interface, as required.

Hi all!
I've Run into a problem in developing my latest VB App, how would you launch a console
window from a winform and write to and read from it using vb's ReadLine() and WriteLine()?
This is what i have so far:
Dim OutputConsole As Console
... Yep, that's it, i can't figure out how to actually show the console window, even thougn ( I think), it is actually there.
Thanks
MrWolfy

Hi,
I know of no way to add a visible Console to a Windows app.
AFAIK the only (easy) way to get a Console is by creating a "Console Application", which always
has a Console (which can be hidden after it has been shown initially) and which can
or can not behave as a regular Windows app, depending on your code.
|

Hi Again!
Thanks for your help, maybe i'll dress up a winform to look like a console window and
add a keylistener to run commands.
Thanks Again
MrWolfy
