Hi all,

I tried to change the title of Sales Blanket Agreement form to Investment in SDK by using visual basic but the helped codes I got are in C#, I am not good in C#.

How can I add ItemEvent in C# in order to use below codes for changing form title.

On your ItemEvent, add the code below:

if(pVal.BeforeAction && pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_LOAD && pVal.FormTypeEx == "1250000100")
{
       SAPbouiCOM.Form oForm = SBO_Application.Forms.Item(FormUID);
       oForm.Title = "Investment";
}<br>

I tried to search how I can add ItemEvent in C# but there is no success.

Please anyone can help me

Hi Rurangwa,

Your application should have only code in unique language or C# or VB. You can easily convert the code above from C# to VB with http://converter.telerik.com/.

The code converted to VB:

If pVal.BeforeAction AndAlso pVal.EventType = SAPbouiCOM.BoEventTypes.et_FORM_LOAD AndAlso pVal.FormTypeEx = "1250000100" Then
	Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.Item(FormUID)
	oForm.Title = "Investment"
End If

About how to use ItemEvent you can see the samples provided on the SDK folder.

C#:

C:\Program Files (x86)\SAP\SAP Business One SDK\Samples\COM UI\CSharp\11.SystemFormManipulation

VB:

C:\Program Files (x86)\SAP\SAP Business One SDK\Samples\COM UI\VB.NET\11.SystemFormManipulation

Hope it helps.

Kind Regards,

Hi Diego,

That's very good,

I tried to edit the codes in C:\Program Files (x86)\SAP\SAP Business One SDK\Samples\COM UI\VB.NET\11.SystemFormManipulation and I added the codes you provided in ItemEvent (but in 11.SystemFormManipulation) if I press run button in VB it runs successfully and then if I click Sales Blanket Agreement form in SAP B1 it brings title Investment title, but if I click Add, Previous, Next or Find button in tool bar the form displays original titles.

How can I solve that problem?

That's the codes I used

Public Class SystemForm
    Private WithEvents SBO_Application As SAPbouiCOM.Application
    Private Sub SetApplication()
        Dim SboGuiApi As SAPbouiCOM.SboGuiApi
        Dim sConnectionString As String
        SboGuiApi = New SAPbouiCOM.SboGuiApi()
        sConnectionString = Command()
        SboGuiApi.Connect(sConnectionString)
        SBO_Application = SboGuiApi.GetApplication()
    End Sub
    Public Sub New()
        MyBase.New()
        SetApplication()
    End Sub
    Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent
        If pVal.BeforeAction AndAlso pVal.EventType = SAPbouiCOM.BoEventTypes.et_FORM_LOAD AndAlso pVal.FormTypeEx = "1250000100" Then
            Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.Item(FormUID)
            oForm.Title = "Investment"
        End If
    End Sub
End Class

Please anyone can help me

Hi Diego,

As it seems ItemEvent is not working with MenuEvent

So I tried to add the following codes of MenuEvent but there is one error

    Private Sub SBO_Application_MenuEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.MenuEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.MenuEvent
        If pVal.BeforeAction AndAlso pVal.EventType = SAPbouiCOM.BoEventTypes.et_FORM_LOAD AndAlso pVal.FormTypeEx = "1250000100" Then
            Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.Item(FormUID)
            oForm.Title = "Investment"
        End If
    End Sub

The error found to MenuEvent to this line Handles SBO_Application.MenuEvent

Error1Method 'Private Sub SBO_Application_MenuEvent(FormUID As String, ByRef pVal As SAPbouiCOM.MenuEvent, ByRef BubbleEvent As Boolean)' cannot handle event 'Public Event MenuEvent(ByRef pVal As SAPbouiCOM.MenuEvent, ByRef BubbleEvent As Boolean)' because they do not have a compatible signature.

How can I solve this error? I think this can allow the form to continue to display Investment title even if I click menu buttons

Please help me

Hi Rurangwa,

It is a strange situation. By menuEvent you can do this something like this:

    Private Sub SBO_Application_MenuEvent(ByRef pVal As SAPbouiCOM.MenuEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.MenuEvent
        If pVal.MenuUID.Equals("1288") Or pVal.MenuUID.Equals("1289") Or pVal.MenuUID.Equals("1290") Or pVal.MenuUID.Equals("1291") Then
            If SBO_Application.Forms.ActiveForm.TypeEx.Equals("1250000100") Then
                SBO_Application.Forms.ActiveForm.Title = "Investiment"
            End If
        End If
    End Sub

But really I didn't like the effect of this situation. Unfortunately I don't have any other approach for this situation.

Kind Regards,

Exactly, right and very good Diego!!!!!! That's what I wanted before. Please allow me to ask you one more simple question I edited all that codes in sample of C:\Program Files (x86)\SAP\SAP Business One SDK\Samples\COM UI\VB.NET\11.SystemFormManipulation, so will I create and package addon from this sample or I will add that codes in system form which I will import it in Visual Studio? Thank you for your help

Hi Rurangwa,

That works best for you. But I suggest you create your project. Only remember that the SystemForm sample there are more code that can be not necessary for you.

Kind Regards,

Yes, addon works fine in 32 bit, I want to do test in 64 bit.

Thank you
