I've been puzzling over something, and hopefully someone here can help me figure it out.
In Access 2000, I have two forms... let's call them formA and formB. Users enter data first into formA. Then in certain circumstances, they need to complete formB. Four of the controls on FormB pull identical information as 4 of the controls on formA. I want to set up a command button on formA that opens formB and automatically populates these 4 controls.
My question is how to make this happen.
Can it be done with formA based on tableA, and formB based on a query combining tableB with the 4 fields from tableA, joining on the primary key [ID] from tableA and foreign key [IDtableA] from tableB? I can't get this to work.
At best, I've created a control on formB with [IDtableA] as source -- when I manually enter the corresponding [ID] number, the other corresponding fields will populate automatically. But I don't want to have to enter that number manually.
Do both forms have to be constructed based on the same table? Do my fields from tableB have to be incorporated into tableA to make this work? If formB were a subform directly on formA, it would automatically pick up that ID number. Isn't there some way to make this happen when opening formB through a command button on formA? It's kind of an 'external subform', at least in my mind...

There need be no correlation between the Forms whatsoever, or they may be related, the choice is yours. You are simply transferring data from one Form to the next. The one thing you must be aware of, however, is to make sure the Data Types of the underlying Fields are consistent within the transfer. For instance, if you are transferring the Text Value "One" from [Field1] in FormA to [Field1] in FormB, where the Control Source in [Field1]/FormB is Numeric, you will eventually get a Data type mismatch Error. -
'Transferring Field Values from FormA to FormB via the Click() Event of a Command Button
-
DoCmd.OpenForm "FormB"
-
-
Forms!FormB![Field1] = Me![Field1]
-
Forms!FormB![Field2] = Me![Field2]
-
Forms!FormB![Field3] = Me![Field3]
-
Forms!FormB![Field4] = Me![Field4]

I think there needs to be one more step in the code... is there a way to make it open FormB to a new record for data entry? Otherwise it appears to be overriding the data in an existing record.
Or do I need to set up FormB with the data entry property set to "yes", and save the same form as FormC with data entry set to "no" for reviewing all records?

It occurs to me that there should only be one FormB for each FormA. I don't want a user to create a second FormB if one already exists. I've set it so that FormB contains a control (let's call it control5) that contains the primary key for FormA, and allows no duplicates. But a user could go about entering lots of data in FormB before trying to save it and getting an error message. So I'm wondering if it's possible to create an if-then statement that says "If this ID number already exists in control5 of any record of FormB, then open FormB to that record; else open to a new record."
Can this be done?

You could test the Record Source of Form B, something like: -
If DCount("*", "<Record Source for Form B>", "[ID] = " & Forms![FormB]![Control5]) > 0 Then
-
'ID already exists
-
Else
-
'proceed as Normal
-
End If

Adding this code, I'm getting an error message saying that the database can't find FormB. I know I've got it spelled correctly. Any ideas?

Does a FormB physically exist in your Database?

Ok, I'm quite a newbie, so this question may appear silly. I'm using
g++ 3.3.x.
I had been taught that an array isn't a lot different from a pointer
(in fact you can use the pointer arithmetics to "browse" it). So I
expected that when I run this program, I get both c1.A and c2.A
pointing to the same address, and changing c1.A means that also c2.A
changes too.

I was hoping to have the tables (the frm files) included in a subdirectory
