Re: Delete a record based on a value entered by the user and display the rest of the records

For general purpose operations - the built in macros are fairly ideal
because they don't require any maintenance. But if you need to
customize some operation - the macro is not the most ideal way to go
because they are not easy to customize. Thus, you would use VBA to
write custom procedures/functions.

As for "refreshing " your listbox with the current rows in your table -
just add this to the sample procedure:

Private Sub Command1_Click( )
DoCmd.SetWarnin gs False
If MsgBox("Do you want to delete this record?",vbYesN o, "Delete Record
Yes/No") = vbYes Then
DoCmd.RunSql "Delete * From tblPars Where PartNumber = '" & txtFind &
"'"
End If
listbox1.Rowsou rce = "Select fldx From tblParts"
listbox1.Requer y
Me.Requery
DoCmd.SetWarnin gs True

End If

Try something like this in a command button:

Private Sub Command1_Click( )
DoCmd.SetWarnin gs False
If MsgBox("Do you want to delete this record?",vbYesN o, "Delete Record

Note: to make the code more readable - you may want to rename txtFind as
txtPartNumber.  Also, when using parameters in a query as above - you
have to delimit the parameter with single quotes ' ' if it is a string.
In Jet sql -- data parameters are delimted with the # symbol.  Number do
not require delimiting.  I also temporarily disabled the default
warnings message and then re-enable it at the end of the procedure.
Otherwise you will get the default message everytime you delete
something:

1 Record is about to be deleted.  Continue Yes/No?

Well, I had one more question ---
how would I show all the records minus the deleted record in the
lstBox. I would like to refresh the lstBox with the right information.
Currently it is showing all the records.

Also, I would like to know what is wrong with the way I have set the
macro originally.

Thanks,
Sangeeta.

Re: Delete a record based on a value entered by the user and display the rest of the records

Correction: Date Parameters #3/25/2007# require the # symbol as the
delimeter in Jet Sql. Most sql languages use the single quotes ' ' for
delimiting dates the same as strings. That I know, only Jet sql (Access
Jet sql) uses the # symbol for delimiting dates.

Hi,

I would like to delete a record based on a user entered string. Here
are the
details. I have a txtFind textbox. A string is entered by the user.
Based on
that string value it displays that one record in the fields in the
frmDeleteCompon ent form. There is also a lstDelete listBox which
displays all
the record. But for some reason it does not delete that particular
record as
requested by the user. I have written the sequence I am following and
I am
hoping that someon is able to answer my question. I need help.

Thanks,
SA

My code in frmDeleteCompon ent:

Title = "Delete Component Confiramtion"
response = MsgBox(Msg, Style, Title)

If response = vbYes Then
stDocName = "macroDelet e"
DoCmd.RunMacro stDocName
End If

Exit_cmdDelete_ Click:
Exit Sub

Err_cmdDelete_C lick:
