Objek.

Just when I was rejoicing about the simple solutions I have discovered, I'm facing a new problem: a bug Microsoft did not fix since 2003 (or probably earlier than that) with Multipage control, which shows wrong Page content.

The Multipage's Tab and all other Controls on the Userform are referring to the Page I wanted, say PageMe but the content dispayed in the Multipage is from another page, say PageYou. This happens after a Multipage_Change event procedure which tell the Multipage to return to PageMe if user changes to PageYou but the condition in a TextBox, say TextMsg on PageMe is still not met.

Say PageMe index is 0 and PageYou index is 1, and the Multipage name is MultipageUs, the simple code is something like this:

Private Sub MultipageUs_Change()
     If TextMsg = "#" Then MultipageUs.Value = 0
End Sub

Since I cannot disclose much information about my actual project here, the problem is basically similar to the ones found in the following links:

http://dailydoseofexcel.com/archives/2004/07/20/bug-multipage-controls-on-2003/

I've tried the workarounds suggested using Application.OnTime, the Value = Value - 1 etc, but still the problem persist.

My only option here is to disable something that I really do not want to disable.

Although I'm not sure if there if there is anyone who read my post, I'm going to take my chances: Do you have any other possible solution or a workaround? If you have, please tell me and I will treat you with Sate Jalee if you ever come to Kerteh.

Thanks.

Nakharom.

It is one of those "duh" situation.

I am working on a VBA project which links Excel with SAP FrontEnd.

Bla bla bla... I discovered a problem whereby I can't remove focus from a Userform Button after clicking on a Msgbox prompt or when another sub-Userform is loaded.

Yes, I tried using SetFocus to another Control, putting the whole object reference i.e. Userform1.Button1.SetFocus, setting a dirty Boolean to terminate, setting another event etc... yet it still didn't work. No error was thrown by VBA though, but there was a problem since there is another procedure to disable the darn Button after pressing 'No' in the Msgbox prompt or cancelling the sub-Userform. Basically, in the scenario I was testing, I end up with a disabled Button which has focus. Weird and everything else stuck except for the Esc key.

After two sleepless nights trying to figure a workaround, I was still unable to solve this issue.

Yes, I googled too... that is the first thing anyone will do when stuck with a problem isn't it? Anyway, if someone has discovered the solution out there, it will probably end up in page 2 or 3 (or further down...)

Finally just now, I discovered the solution: a Control property which is rarely mentioned in VBA books: TakeFocusOnClick.

I set it to False and voila! Problem solved!

I also I discovered how to reactivate Excel window after SAP CreateSession on an active GuiSession object. 

I tried AppActivate and even an API call procedure which I don't even understand but Excel icon will only blinks on the taskbar. Excel did not actually open back and I still see the ugly SAP interface. 

Solution was using GuiMainWindow.Iconify method. It minimizes the SAP GUI window and I got what I wanted.

Ah, two simple solutions for problem I was having for days.

Puas.

Itu

As expected, no one commented my last post. Never mind, I'm posting my solution anyway.

Be warned though, as a non-programmer who only started using Excel VBA less than a month ago, my codes are not really efficient.

Nevertheless, the trainer for VBA fundamental offer this advice before our session ended;
"As long as your code is working, who cares whether it is efficient or not? You are not a programmer. Even if your code is super efficient, PC nowadays are so fast the different will only be like a few seconds... or milliseconds. What important is you understand your codes and able to use it"
For those of you who never use VBA before, here's a quick guide to start:
1. Open MS Excel, press alt + F11 to open the VB Editor.
2. At the menu bar, Insert > Module. You write your codes in here.

Here's how I did it:

1. Use VBA Split function to create an array from the cell with the equipment list.

Sub BreakItUp()

Dim eqListCombined As String
Dim eqList As Variant
Dim eqListNo As Integer

eqListCombined = ActiveCell.Value

eqList = Split(eqListCombined, Chr(10))
For eqListNo = LBound(eqList) To UBound(eqList)
   ActiveCell.Offset(1, 0).Select
   Selection.EntireRow.Insert
   ActiveCell.Value = eqList(eqListNo)
Next eqListNo




2. Copy down everything on the left side of the initial cell.

Dim i As Integer
Dim KiraColumn As Integer

KiraColumn = ActiveCell.Column
ActiveCell.Offset(0 - eqListNo, 1 - KiraColumn).Resize(1, KiraColumn - 1).Copy
ActiveCell.Offset(0 - eqListNo, 1 - KiraColumn).Select
For i = 1 To eqListNo
    ActiveCell.Offset(1, 0).PasteSpecial xlPasteValues
Next i
Application.CutCopyMode = False


3. Copy down everything on the right side of the initial cell.

Dim KiraRange As Integer
Dim j As Integer

ActiveCell.Offset(0 - eqListNo, KiraColumn).Select
KiraRange = ActiveCell.CurrentRegion.Columns.Count - ActiveCell.Column + 1
ActiveCell.Resize(1, KiraRange).Copy
For j = 1 To eqListNo
    ActiveCell.Offset(1, 0).PasteSpecial xlPasteValues
Next j
Application.CutCopyMode = False


4. Calculate the manhour per equipment on the right side of the intial cell

Dim k As Integer
Dim m As Integer

ActiveCell.Offset(1 - eqListNo, 0).Select
For k = 1 To eqListNo
    For m = 1 To KiraRange
        If ActiveCell.Offset(0, m) <> "" And IsNumeric(ActiveCell.Offset(0, m).Value) Then
            ActiveCell.Offset(0, m) = ActiveCell.Offset(0, m) / eqListNo
        End If
    Next m
    ActiveCell.Offset(1, 0).Select
Next k


5. Go back to the 1st cell and delete the entire row then go to the next equipment list row to be processed.

ActiveCell.Offset(-1 - eqListNo, -1).Select
Selection.EntireRow.Delete

ActiveCell.offset(eqListNo,0).select

End Sub


Basically, the above codes should be able to do the things I described in my previous post. By assigning the macro to a letter, say 'b', I can just press 'ctrl + b' all the way to the last line.

Of course in my example, there are only six rows. In the real worksheets that I wanted to process, the row number ranges from just seven to 1,873 rows per sheet.

Boleh patah jari woo tekan 'ctrl + b' 1,873 kali! So...

6. Create a simple procedure to loop the above process until it reaches a blank cell.

Sub loopBreakItUp()
Do Until ActiveCell.Value = ""
    Call BreakItUp
Loop
End Sub 


Maka selamatlah jari kita dari kelenguhan.

In my module, I've entered some other codes to check whether the right cell is selected, to remove funny characters, to skip rows which do not require processing (i.e. the cell contains only one equipment). etc. But you probably wont need them anyway.

If you are a programmer or used VBA before, you probably noticed that my codes are not 'hard-coded'. This means you can probably use this code even if the format of your data is not as same as mine.

So, that's it. My first Excel 2010 VBA project. Did it to assist my colleague, Mek Yam with her tasks.

Thanks for going through it. Feedback and question are always appreciated.

p/s: You can use the above codes at your own risk. Please backup any file before you execute the VBA codes.

Haprak

So, let me just share something about my first VBA project in MS Excel 2010.

I have a database of Preventive Planned Maintenance (PPM) activities saved in Excel worksheets. The PPMs are organized in a roster, where each PPM takes one row of the worksheet. For each PPM, there is a list of equipment stored in one cell, and manhours stored in a few cells along with other information.

Here's a screenshot of the original data:


I want the equipment list to be separated into individual cells in a new row with its PPM data copied, and the manhours divided per equipment.

Basically, this is the result that I want:


Before I share my codes, how would you do it?

Erm... I'm asking like someone actually read my blog... but who knows...
