Re: [MS_AccessPros] Checklist with a twist 1 - different input types


Hi Adam,

I use a table corresponding to the Access data type number (DatTypN) for stuff like this:

DatTypN DatTypS DatTypeS DatTypN_
1 YN Boolean 4
2 Byt Byte 4
3 Int Integer 4
4 Lng Long 4
5 Cur Currency 5
6 Sgl Single 7
7 Dbl Double 7
8 Date Date/Time 8
9 Bin Binary
10 Text ShortText 10
11 Ole OLE Binary BMP
12 Memo LongText 10
15 Guid Guid
16 BigInt Big Integer
17 BinVar Binary Variable
18 TxtFix Fixed Text 10
19 oNum Numeric ODBC
20 oDec Decimal ODBC
21 oFloat Float ODBC
22 oTime Time ODBC
23 oDatTim DateTime ODBC
101 Att Attachment
102 mvByt Byte MV
103 mvInt Integer MV
104 mvLng Long Integer MV
105 mvSgl Single MV
106 mvDbl Double MV
107 mvGuid GUID MV
108 mvDec Decimal MV
109 mvTxt Text MV

DatTypN_ is for rolling up data types

I would rethink OptionA and OptionB.  The RecordSource should report all answers in a calculated text field (that can't be edited) so they line up.  Then, an edit button that will turn on the appropriate control (checkbox, combo, textbox, etc) to fill out with the value with validation for the proper data type.  Generally, I store:
- yn (can also use Long to store this)
- long integer
- currency
- text

warm regards,

~ have an awesome day ~

This is the first of two checklist questions, which I'll post in separate topics.

With this topic, the checklist responses may can have different types of input: date, Y-N, short text. Also, some of the responses may determine the next steps. I'm looking for feedback on my approach, and/or advice on a better one.

Assume the standard checklist vertical structure: tblChecklistMaster (key ChecklistID), tblChecklistTasks (TaskID), tblChecklistData (ChecklistID, TaskID). When a new project is added to tblChecklistMaster, the tasks are copied from tblChecklistTasks to tblChecklistData.

For different input types, my idea is to add a field to tblChecklistTasks, let's call it InputType, long integer; e.g., 1=date, 2=Y-N, 3=text). On tblChecklistData, make the field Done as short text. On the subform (based on tblChecklistData, main form based on tblChecklistMaster), have code that will do different things, when the Done text box is clicked, depending on InputType:

  1. Enter today's date
  2. Toggle between Y-N
  3. Allow the input of text.

For next steps, my idea is to add another table, tblChecklistTaskOptions, with 3 fields: TaskID (link to tblChecklistTasks), OptionA, OptionB. TaskID would be the originating ID of the Task that determines the next set of tasks. OptionA would be the TaskIDs if Y is chosen, OptionB if N is chosen. There can be multiple entries of next steps for each originating TaskID. Initially, I wouldn't populate tblChecklistData with any task that is in OptionAorB. When a choice is made on the originating task, I would then populate tblChecklistData with the next step tasks from OptionAorB. If the choice were changed, I could delete one set of next steps and replace it with another. tblChecklistTasks has the field SortOrder, so the next step tasks would go in the right place when the form is refreshed.

I know how to do the coding of this. I'm looking to see if my approach/idea is off base.
