UI: Messagebox when button is clicked

[Former Member]

Hello all

I've created a VERY simple form with a button on it. This is the code:

'Create the form:

frmVareAddOn = SBO_Application.Forms.Add("VareAddOnForm")

frmVareAddOn.Height = 599

frmVareAddOn.Left = 275

frmVareAddOn.Title = "My button-form"

frmVareAddOn.Top = 48

frmVareAddOn.Width = 473

'Create the button

oItem = frmVareAddOn.Items.Add("btnHello", SAPbouiCOM.BoFormItemTypes.it_BUTTON)

oItem.Height = 19

oItem.Left = 365

oItem.Top = 28

oItem.Width = 65

oButton = oItem.Specific

oButton.Caption = "Hello"

When I run the project, the form with the button is shown - but how can I show a MessageBox when the button is clicked?

Thank you for posting.

I am now catching the events, when my buttons are clicked - I do this with the ITEM_PRESSED event.

But everytime i click my button - the event happens twice... I get the messagebox two times in a row. How do I solve this?

Hi Henrik,

several events will come twice:

Before and after SBO performs it's own tasks in reaction to the specific event, you are informed about that.

The property of the ItemEvent object reflecting this is

"Before_Action". The UI API helpfile states that this "Returns a value specifying if the event was issued before SAP Business One application handled the event."

To prevent further processing by SBO etc. in case of "Before_Action=True", set "BubbleEvent" to False. (See "Remarks" to the ItemEvent Event)

Hello Henrik,

see then ItemEvent of the Application Object in UI Help-File.

There is also a sample named "CatchingEvents Sample".

Hello Henrik,

you can catch an item event for this.

Please

- check the "Catching events" sample in the "Developer area" for "SAP Business One" for details and/or

- see the help file for SAP Business One UI API ("Programming with the UI API" / "Event Handling" / ...) or

- see the help file for SAP Business One UI API ("UI API Reference" / "Overview" / "Events" / "Item Events").

In VB .NET e.g. the handler looks like this:

Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent

"pVal" contains all the information you need for your purposes.

In addition please "search" the UI API helpfile for further information about "MessageBox"...

Regards,

Frank

PS (Just FYI): There's a training course for the SBO SDK (TB1300) that will help you to get started with SDK development.
