Sometimes Notes' imperfections go beyond the annoying and become real problems. For example, you can't show values
with embedded commas in a ListBox for a user to select from. When you want to present a list of customer names, this is a real roadblock, as company names with the formats "ABC, INC." and "SMITH, SMITH, & JONES" are very common. As I tried to come up with a workaround, I found the following helpful hint on Notes.Net
Armed with this information, here's how I implemented a solution to this issue:
Sub CommaSubstitute(array As Variant, action As String, changed As Integer) %REM Purpose: ======= When values with embedded commas appear in a listbox for selection, the comma acts as a value separator, although this is not desired. There is no way to disable this. So this routine is needed to "tweak" existing commas so they don't act this way. Process: ======= We replace all commas with high-order-bit (HOB) commas, which look identical to the user, but Notes does not recognize them as a value separator. We can also do the reverse, replacing any HOB commas with its original ones. This sub replaces ALL commas, even multiple ones in the same piece of text. Important! Any time an array is "tweaked" so the user can select from it, it should be "untweaked" afterwards! For example, if you forget to do this, and you try to use the selected value as a key to retrieve a document, the document will never be found. You can use the returned value of "changed" to see if this step is necessary: if True, the array was changed, so you will have to "untweak" it; if False, you can skip this step. Arguments: ========= ARRAY = the input array, which will be reviewed and changed by this sub. ACTION = "TWEAK" or "UNTWEAK" = should we replace the commas with HOB commas, or back out any such existing replacements? CHANGED = a True/False flag. If False, nothing was changed; if True, at least one value was changed.
%END REM changed = False Dim SearchValue As String, ReplacementValue As String Dim x As Integer, i As Integer, L As Integer If action = "TWEAK" Then SearchValue = "," ReplacementValue = Chr(0130) Elseif action = "UNTWEAK" Then SearchValue = Chr(0130) ReplacementValue = "," Else Messagebox "CommaSubstitute called with invalid argument = " & action & " Please contact Support.", 48, "System Error" Exit Sub End If Forall valu In array L = Len(valu) For i = 1 To L If Mid(valu, i, 1) = SearchValue Then Mid(valu, i, 1) = ReplacementValue changed = True End If Next End Forall End Sub
