Hi,

In your message you have not specified the language you are using in your application but assuming that you are using VB 6.0, here is the code to erase the content of an array -

updating a form

Hi i'm writing a windows application using vb.net and I need some way of refreshing the form so that new values (in this case a new template) is added to a listbox on the form once it is created.How do I do this? I would think that I just would need to rebind the datasource for the listbox to the dataset table. I'm just not sure what form event to put the code in or if this is the right way to do it? It cant be in the form load event because I dont want the user to have to close and reopen the form.

I'm not sure what you mean.
Do you have 2 forms or how do you create the new template??

if you create it on a second form and you call that form in a button you can open the second form as showdialog and then put the reloadcode for the listbox after that (the code will wait for the seconde form to close)

you can also work with custom events.
declare a custom event on the second form, when you open the second form add a handler to it
(addhandler form2.customevent, addressof reloadlistbox) and then in the second form you raise the event when the template is created

Without a better explination of how you'r program is working this is the best advice I can give you.

If my help was helpfull let me know, if not let me know why.

I create the template on the same form. once the user clicks save I want it to show the new templatname in the listbox on the form. it currently only updates the lisbox once I close and then reopen the form.Thanks for the reply

then just update the listbox in the save button as last line(s) of code

Am now Sure that the Data from the user in the Presentation Layer,does go to Business Layer in my BLL Class.Here is the code for a Button Save in my Form in the Presentation Layer.

Try

        Dim objproperty As New PropertyBLL
        objproperty.Num_keyp = txtNum_key.Text
        objproperty.Extensionp = txtExtension.Text
        objproperty.Cell_IDp = txtCell_ID.Text
        objproperty.Actual_Extentp = txtActual_Extent.Text
        objproperty.Lis_keyp = txtlis_key.Text
        objproperty.Func_keyp = txtFunc_key.Text
        objproperty.Geocodep = txtGeocode.Text
    Catch Err As PropertyException
        MessageBox.Show(Err.Message, "Property")
        Select Case Err.FieldInError
            Case "Num key"
                With txtNum_key
                    .SelectAll()
                    .Focus()
                End With
            Case "Cell ID"
                With txtCell_ID
                    .SelectAll()
                    .Focus()
                End With
            Case "Extension"
                With txtExtension
                    .SelectAll()
                    .Focus()
                End With



        End Select
    End Try

The Business Logic will validate the input from a user from the Presentation Layer. The thing i want to know is how does the Dal Collect the validated data from BLl and Execute it.

Please Post Explanation and Examplary code.

Thanks

No-one is going to read all of this. What do you need help with ? Can you break this down into something that can be understood in less than an evening ?

Have you considered using a stored proc ?

Yes i haved Considerd using the Scored Procedure, but i thought first understand how does BLL send data to Dal so it can be executed..

Thanks

The answer to that is self evident, the DAL either takes instances of entity classes that contain the data needed, or parameters that contain the data required. Just like any other function you'd write, in any program.

Creating a custom control in VB

Hi

I've been trying to create a custom textbox control using Visual studio 2005(VB.Net) with the properties that a normal texbox have with additional appearance and functionality that looks like this |_|_|_|_|_|_|_|_|_|_|_|_|.

If I need to use it for title it will be something like this |_|_|_|_|

For an address |_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
etc.

The has to be only one entry in each box and be able to set a colour for the lines and this lines must touch the textbox borders and not live spaces between like on this message.

I've been using the Web Costom control in the Web Control Library to do this and read GDI+, but something is just missing,

Can anyone please help me out with this I need it for my peoject.

Thanks

You can't use graphics with a web control. A web control is rendered as html code, so that is what you are limited to.

Can you do it in a Windows Application then

Guffa30-Sep-07 23:09

Yes. You just override the Paint method. That will be called whenever the control is drawn, so you call the base implementation of the method to do the original drawing, then you can draw whatever you like on the control. The event arguments sent to the method contains a graphics object that you should use for doing the drawing.

Guffa is right, but the caveat is that the underlying text control in windows draws itself outside of the paint event often, so doing a custom text control, while possible, is a real PITA.

I must hide the welcome screen. then the login form must be appear. my login form's back ground is in transparent. when load my login form,the welcome screenform is hide but that is appear behind the login form. when load my login form, the welcome screen form might not appear.
How can i solve this problem?

Re: hide the welcome screen

I can't follow this. The login form is covering the welcome form ? Don't show it until the welcome is closed, or make the welcome screen topmost.

don't know if this is what you want but you can put you'r welcome screen as splash screen
in the properties of you'r project
then the welcome screen will appear as first screen for a few seconds and after that the project will start

If my help was helpfull let me know, if not let me know why.

The only way we learn is by making mistaks.
