Visual Basic question

Dear experts

I have some trouble with data control. The refresh method runs one time.
If I want to repeat it again an error occurs.

I made the following steps

I made a temporary table for changing values:
-db.Execute  "select * into [tempTableName] from [TableName]",dbFailOnError
-db.TableDefs.Refresh
-data.RecordSource=tempTableName
-data.refresh ' no error occurs at this first execution of refresh.

Then I change a value in dbGrid (dbgrid.DataSource=data )
-data.UpdateRecord
Save table with  tempTableName to table withTableName
-data.RecordSource="dummy" 'is a empty table in db
-data.refresh ' no error occurs
-db.Execute "drop table [TableName]",dbFailOnError
-db.Execute "select * into [TableName] from [tempTableName]",dbFailOnError
-db.Execute "drop table [tempTableName]",dbFailOnError
-db.TableDefs.Refresh
Then I want to show the same table in the dbGrid
-I made a temporary table and then
-data.RecordSource=tempTableName
An error occurs, if the data.refresh method is executed again
Remark:
The error occurs at one special  table only. The table consists of 41 Columns,13 Rows.
At all other tables no error occurs.
Error message occurs in different VB4 moduls:
 
dbGrid.ocx 0005:341B
DAO2516.DLL 002D:0044
...

Thanks for any help!

Didn't the error occur because you executed a 'drop tempTableName' before setting the RecordSource to that table that does not exist any more?  The Refresh probably failed because of this.

If I'm getting something wrong here, please comment.

Dear dansari

I do have the tempTableName indeed.
Because I deleted them after SYSTEM CRASH.

I execute a ' select * into tempTableName from TableName ' before
the RecordSource will be set again.

Thanks
