So I have a bunch of listboxes on my VB form. I created a command button too.
I want to make it so that if I press the command button it cycles from the current listbox, which has focus, to the previous listbox. It's the equivalent of using TAB and SHIFT TAB to cycle amongst the control. SHIFT TAB goes backwards in the cycle, TAB goes forward in the cycle. I vaguely remember there was a way to go back & forth in the "tab cycle".
How do I do this?
You can;
Private mCurrentListboxTabIndex As Integer
'wire up, simpler if you use a control array
Private Sub List1_GotFocus()
mCurrentListboxTabIndex = List1.TabIndex
End Sub
Private Sub List2_GotFocus()
mCurrentListboxTabIndex = List2.TabIndex
End Sub
Private Sub List3_GotFocus()
mCurrentListboxTabIndex = List3.TabIndex
End Sub
Private Sub btnPrev_Click()
FocusListBoxByTabIndex -1
End Sub
Private Sub btnNext_Click()
FocusListBoxByTabIndex 1
End Sub
Private Sub FocusListBoxByTabIndex(offset As Long)
Dim ctrl As VB.Control
For Each ctrl In Me
If TypeOf ctrl Is ListBox Then
If ctrl.TabIndex = mCurrentListboxTabIndex + offset Then
ctrl.SetFocus
Exit Sub
End If
End If
Next
End Sub

I am trying to create two tables which mirror changes made to any of them to one another automatically.
To that end, I added event listeners which are triggered when the cells of these tables are edited by the user.
Unfortunately, editing one of the tables causes LibreOffice to crash, even though the changes are indeed reflected correctly, as seen upon reopening the file.
I thought the crash might be due to a never-ending circular reference, but it still crashes after it has been made non-circular (by commenting out the relevant parts of the code so that changes are reflected only one way rather than both ways).
I noticed the code worked fine when writing to a cell that didn't have an event listener set to it.
How can I write to one of the cells with event listeners set to them without causing LibreOffice to crash?
You may want to download the following file. Please run Main and then try editing the cell C3 of the Planning sheet. The arbitrary string "C" should be written in the cell C4 of the Services sheet.
Here is a simplified version of the code :
REM ***** BASIC *****
const SERVICESSHEET_NUMBER = 2
const SERVICESSHEET_SERVICES_COLUMN = 2
Type cellStruct
columnNumber As Integer
rowNumber As Integer
End Type
Sub UpdateServicesSheet(editedCell As cellStruct, newValue As String)
Dim oSheets
Dim servicesSheet
oSheets = ThisComponent.getSheets()
servicesSheet = oSheets.getByIndex(SERVICESSHEET_NUMBER)
servicesSheet.getCellByPosition(SERVICESSHEET_SERVICES_COLUMN, 3).setString(newValue)
End Sub
Private oListener, cellRange as Object
Sub AddListener
Dim sheet, cell as Object
sheet = ThisComponent.Sheets.getByIndex(0) 'get leftmost sheet
servicesSheet = ThisComponent.Sheets.getByIndex(2)
cellRange = sheet.getCellrangeByName("C3")
oListener = createUnoListener("Modify_","com.sun.star.util.XModifyListener") 'create a listener
cellRange.addModifyListener(oListener) 'register the listener
cellRange = servicesSheet.getCellrangeByName("C4")
oListener = createUnoListener("Modify_","com.sun.star.util.XModifyListener") 'create a listener
cellRange.addModifyListener(oListener) 'register the listener
End Sub
global CircularReferenceAllowed As boolean
Sub Modify_modified(oEv)
Dim editedCell As cellStruct
Dim newValue As String
editedCell.columnNumber = 2
editedCell.rowNumber = 2
If CircularReferenceAllowed Then
CircularReferenceAllowed = false
UpdateServicesSheet(editedCell, "C")
End If
End Sub
Sub Modify_disposing(oEv)
End Sub
Sub RmvListener
cellRange.removeModifyListener(oListener)
End Sub
Sub Main
CircularReferenceAllowed = true
AddListener
End Sub

It seems like the event trigger is within another event's function is causing the crash. In any case, the solution is to remove the listener, then add it back after modifying the other cell.
You do need to global the Listener and the Cell objects to make this work.
This code is simplified to work on C3 and C15 on the first sheet. It would also output some information on C14, which isn't really necessary for your purpose, but I use it to see what's happening. You need to adopt the according to what you need.
global goListener as Object
global goListener2 as Object
global goCellR as Object
global goCellR2 as Object
global goSheet as Object
global giRun as integer
global giUpd as Integer
Sub Modify_modified(oEv)
Dim sCurStr$
Dim sNewStr As String
'xRay oEv
giRun = giRun + 1
sCurStr = oEv.source.string
oCell = goSheet.getCellByPosition(2, 14)
If (oCell.getString() <> sCurStr) Then
' only update if it's different.
giUpd = giUpd + 1
goCellR2.removeModifyListener(goListener2)
oCell.setString(sCurStr)
goCellR2.addModifyListener(goListener2)
End If
sNewStr =sCurStr & " M1 Run=" & giRun & " Upd=" & giUpd
goSheet.getCellByPosition(2, 13).setString(sNewStr)
End Sub
Sub Modify2_modified(oEv)
Dim sCurStr$
Dim sNewStr As String
Dim oCell as Object
'xRay oEv
giRun = giRun + 1
sCurStr = oEv.source.string
oCell = goSheet.getCellByPosition(2, 2)
If (oCell.getString() <> sCurStr) Then
' only update if it's different.
giUpd = giUpd + 1
goCellR.removeModifyListener(goListener)
oCell.setString(sCurStr)
goCellR.addModifyListener(goListener)
End If
sNewStr =sCurStr & " M2 Run=" & giRun & " Upd=" & giUpd
goSheet.getCellByPosition(2, 13).setString(sNewStr)
End Sub
Sub Modify_disposing(oEv)
MsgBox "In Modify_disposing"
End Sub
Sub Modify2_disposing(oEv)
MsgBox "In Modify2_disposing"
End Sub
Sub RmvListener
MsgBox "In RmvListener"
goCellR.removeModifyListener(goListener)
goCellR2.removeModifyListener(goListener2)
End Sub
Sub AddListener
goSheet = ThisComponent.Sheets.getByIndex(0) 'get leftmost goSheet
'servicesSheet = ThisComponent.Sheets.getByIndex(2)
goCellR = goSheet.getCellrangeByName("C3")
goListener = createUnoListener("Modify_","com.sun.star.util.XModifyListener") 'create a listener
goCellR.addModifyListener(goListener) 'register the listener
goCellR2 = goSheet.getCellrangeByName("C15")
goListener2 = createUnoListener("Modify2_","com.sun.star.util.XModifyListener") 'create a listener

I need to add buttons to a form at run time for Access. When clicked each button will need to open a modal form with specific information based on the button clicked. So for instance, if I write a loop to create five buttons and name them button1, button2, button3, button4 and button5; how would I achieve the following:
Private Sub button1_Click()
Msgbox "Button 1 was Clicked"
End Sub
Private Sub button2_Click()
Msgbox "Button 2 was Clicked"
End Sub
Private Sub button3_Click()
Msgbox "Button 3 was Clicked"
End Sub
Private Sub button4_Click()
Msgbox "Button 4 was Clicked"
End Sub
Private Sub button5_Click()
Msgbox "Button 5 was Clicked"
End Sub
This is a simplified version of what I want to achieve but this is the gist of it. Am I thinking about this correctly? Is there better way?
I am using MS Access 2010.
Any help is appreciated. Thanks
Here is how you can create an Event Procedure (Click()) for a Control (Command Button) named cmdDemo on the Current Form
Dim ctl As Control
Dim mdl As Module
Dim frm As Form
Set ctl = Me![cmdDemo] 'Set a Reference to the Command Button
Set frm = Me 'Set a reference to the Form
Set mdl = Me.Module 'Set a Reference to the Form's Code Module
'Create a Click() Event Procedure for the Command Button cmdDemo
lngReturn = mdl.CreateEventProc("Click", ctl.Name)
'Insert a single Line of Code in the Event Procedure
mdl.InsertLines lngReturn + 1, "Msgbox ""Create Procedure Demo"""
Good Afternoon. I've running into a situation I hope someone here can help with. I'm running Office 2010 on Windows XP and have an Excel worksheet that contains a button to show a modal form (Form01). Form01 contains 3 Listboxes of data. Double-Clicking a item in listbox2 will open another modal form (Form02) so the item can be modified. Unloading Form02 will save the data and call a couple of macros to adjust a named range on the host worksheet. This code is stored in a Module, not on the form.
This is where the problem occurs. When Form02 is unloaded and Form01 is accessable, I cannot select anything in listbox1 or listbox3 or buttons on Form01. I have to first select something in listbox2, then I have access to the other controls on the form. I've tried to .SetFocus on the other controls and add DoEvents after the Form02.Show 1 statement with no luck. The only workaround I've found is to hide and reshow Form01 which causes the screen to flicker. Application.ScreenUpdating = False and back to True doesn't seem to help either. I really need to figure out what the other controls are not accessible when Form02 is shown and then closed. Has anyone else experienced this behaviour or might have a suggestion?
Change this
Private Sub lstSiteMaster_DblClick(ByVal Cancel As MSForms.ReturnBoolean)
If lstSiteMaster.ListCount = 0 Then Exit Sub
LoadFrmEditDataset Me.Controls("lstSiteMaster"), "SITE MASTER"
frmEditDataset.Show 1
Unload frmEditDataset
DoEvents
Me.lstSiteMaster.ListIndex = -1
Me.lstSiteList.ListIndex = -1
Me.lstMiniPOR.ListIndex = -1
'''BounceTheForm
End Sub
to
Private Sub lstSiteMaster_DblClick(ByVal Cancel As MSForms.ReturnBoolean)
If lstSiteMaster.ListCount = 0 Then Exit Sub
LoadFrmEditDataset Me.Controls("lstSiteMaster"), "SITE MASTER"
frmEditDataset.Show 1
DoEvents
Me.lstSiteMaster.ListIndex = -1
Me.lstSiteList.ListIndex = -1
Me.lstMiniPOR.ListIndex = -1
'''BounceTheForm
End Sub
AND
this
Private Sub cmdApply_Click()
With Me
UpdateDataset .lblDataset, .lblECR, .lblFA, .lblFieldId, .txtFieldValue, .cboAction, .lblIndex + 2
End With
Me.Hide
End Sub
to
Private Sub cmdApply_Click()
With Me
UpdateDataset .lblDataset, .lblECR, .lblFA, .lblFieldId, .txtFieldValue, .cboAction, .lblIndex + 2
End With
Unload Me
End Sub
I have a function which may take some time to execute.
How can I have a small modal form to show at the start of the function which closes when the function finishes?
Say frmModal is the form you wish to show. At the start of your function put in
frmModal.Show
frmModal.refresh
At the end of your function put in
Unload frmModal
My favorite trick for this is to put the code that is run into the form that is displayed while it is running. Then when it is done call Unload Me
'Code in Form1
Call frmWait.Show(vbModal, Me)
'Code in frmWait
Private Sub Form_Activate()
'Do some work ...
Unload Me
End Sub
when you load the form modal (form1.show vbmodal) then subsequent code is not executed until the model form is closed
a simple way (without api) to simulate what you want is to show the form modeless, and temporary disable the other form
have a look at the differences between command1 and command2 in the following test project :
'3 forms :
' Form1 : name=Form1
' contains 2 command buttons with the name Command1 and Command2
' Form2 and Form3 contain nothing special
Option Explicit
Private Sub Command1_Click()
Dim lngEnd As Long
Form3.Show vbModal
lngEnd = Timer + 5
Do While Timer < lngEnd
Caption = CStr(Timer)
DoEvents
Loop
Unload Form3
End Sub
Private Sub Command2_Click()
Dim lngEnd As Long
Enabled = False
Form2.Show vbModeless, Me
lngEnd = Timer + 5
Do While Timer < lngEnd
Caption = CStr(Timer)
DoEvents
Loop
Enabled = True
Unload Form2
End Sub
I would like to execute some code when a user closes a form using the x button in the top right corner of the window (I have the form load when the excel spreadsheet is opened, and it hides Excel. I want to exit excel once the form is closed, or at least show excel again so the user may exit it manually)
Looking at the form properties, the Unload property is not present, nor am I able to figure out how to make a function which executes when the form is closed.
Unfortunately, coding this in VB is not an option, it must be VBA.
I'm aware of the code needed to unhide Excel or quit it outright, just not how to tie it to the unload event.
You can use QueryClose event of the UserForm as follows:
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = 0 Then
' Your codes
' Tip: If you want to prevent closing UserForm by Close (×) button in the right-top corner of the UserForm, just uncomment the following line:
' Cancel = True
End If
End Sub
You can also use vbFormControlMenu like this:
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = vbFormControlMenu Then
'Your code goes here
End If
End Sub
A colleague was able to provide the answer, including example here for everybody else
Private Sub userform_terminate()
'Code goes here
End Sub
You can use Unload Me in VBA to close a form. Just put the code to close Excel immediately following that.
Private Sub Form_Unload(Cancel As Integer)
Dim msgRes As VbMsgBoxResult
msgRes = MsgBox("Exit form ?", vbYesNo)
If msgRes = vbYes Then
'optional code
ElseIf msgRes = vbNo Then
Cancel = True
End If
End Sub
I was able to prevent the form from closing when the X button was click using the following:
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
Cancel = MsgBox("Please confirm cancellation", vbOKCancel + vbQuestion) = vbCancel
End Sub
try something like this:-
Private Sub Form1_FormClosing(sender as Object, e as FormClosingEventArgs) _
Handles Form1.FormClosing
//Code you want to execute
End Sub
