I have a problem with some contextual menu loaded dynamically through sdk

[Former Member]

Hi everybody,

i have a problem with the Context menu.

For a particular addon, i want to dynamically load a number of menus according to certain values in the mask of SAP, for example the CardCode or ItemCode.

After a certain number of rightclickmouse, "event where i do call a function that create a new menu", SAP show the messagge "

Error: Menu - Not found [66000-27]" or Menu - Already exists !!.

I also tried to create menus with xml files, but I always get errors.

I think there is some problem with the unreleased memory.

This is an example:

This is an example:

Private Function AddMenu(ByVal mnu As String, ByVal subMnu As String, ByVal title As String, _

ByVal pos As Integer, ByVal tipo As SAPbouiCOM.BoMenuType, _

ByVal pathImg As String) As Boolean

Try

Dim mnuItm As SAPbouiCOM.MenuItem = Nothing

Dim mnuItmNew As SAPbouiCOM.MenuItem = Nothing

Dim img As String = IO.Path.Combine(Application.StartupPath, pathImg)

If Not IO.File.Exists(img) Then img = ""

'Get father menu

mnuItm = SBO_Application.Menus.Item(mnu)

Dim oCreationPackage As SAPbouiCOM.MenuCreationParams

oCreationPackage = CType(SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_MenuCreationParams), SAPbouiCOM.MenuCreationParams)

With oCreationPackage

.Type = tipo

.UniqueID = subMnu

.String = title

.Enabled = True

.Checked = False

.Position = pos

End With

'Create new sub menu

If mnuItm.SubMenus IsNot Nothing AndAlso mnuItm.SubMenus.Exists(subMnu) Then

mnuItm.SubMenus.RemoveEx(subMnu)

End If

mnuItmNew = mnuItm.SubMenus.AddEx(oCreationPackage)

System.Runtime.InteropServices.Marshal.ReleaseComObject(mnuItm)

System.Runtime.InteropServices.Marshal.ReleaseComObject(mnuItmNew)

System.Runtime.InteropServices.Marshal.ReleaseComObject(oCreationPackage)

GC.Collect()

Return True

Catch ex As Exception

SBO_Application.MessageBox("Error: " & ex.Message)

Return False

End Try

End Function

Public Sub New()

MyBase.New()

SetApplication()

End Sub

Private Sub SBO_Application_RightClickEvent(ByRef eventInfo As SAPbouiCOM.ContextMenuInfo, ByRef BubbleEvent As Boolean) Handles SBO_Application.RightClickEvent

If eventInfo.BeforeAction Then

'1^ level

AddMenu("1280", "MYMENU_01", "My Main Menu", 1, SAPbouiCOM.BoMenuType.mt_POPUP, "")

'2^ level

AddMenu("MYMENU_01", "MYMENU_11", "Menu 1.1.0", 1, SAPbouiCOM.BoMenuType.mt_POPUP, "")

For i As Integer = 0 To 10

AddMenu("MYMENU_01", "MYMENU_1" & i.ToString, "Menu 1." & i.ToString & ".0", i, SAPbouiCOM.BoMenuType.mt_POPUP, "")

'3^ level

For j As Integer = 0 To 4

AddMenu("MYMENU_1" & i.ToString, "MYMENU_1" & i.ToString & j.ToString, "Menu 1." & i.ToString & ".1", 1, SAPbouiCOM.BoMenuType.mt_STRING, "")

Next

Next

Else

If SBO_Application.Menus.Exists("MYMENU_01") Then SBO_Application.Menus.RemoveEx("MYMENU_01")

End If

End Sub

Thanks in Advance.

Hi,

Check if the Menu Already Exsists then remove it and Add it.

i.e. Before Addtion of the menu...check and remove it

like....

if (oMenus.Exists("M_EMPID"))
                {
                    oMenus.RemoveEx("M_EMPID");
                }
                oMenus.AddEx(oCreationPackage);

Thank you,

but I've tried this solution but there is always the error.

If you try to run my code in the example: ... \ SAP \ SAP Business One SDK \ Samples \ COM UI \ VB.NET \ 05.AddingMenuItems \ you can reproduce the error, just copy and paste the code.
