I have a question. When I try to use this piece of code in my program which will add a supplier to the database, I encounter data type mismatch error. As far as I know, the status of the supplier creates the error.How would I store the values of the radio buttons named radActive and radInactive in the database? Should I use Boolean or a String? I am using Microsoft Access as my database and the field of Status is set to Yes/No.

I have tried repeatedly to use a For Each Next statement inExcel 2003. The intent of this is to ititerate through a predefined selection of cells and set the value of the cell 3 columns to the right based on the value of the cell in the selection.
The latest code I have tried to use is the following:
SR.Range("a5").Activate
SR.Range("a5", ActiveCell.End(xlDown)).Select
Selection.Offset(0, 5).Select
[code]....
Where SR is the active sheet. (I have only been introduced to VBA and code language for a few weeks, so I am learning as fast as I can. Please excuse my ignorance!)When I get to the 'If x.value' line I get the type mismatch error. I have tried to set my "each" to variant variable types and my "collection" (or selection as it were) to different variable types and constantly I am getting this same error regardless of my efforts.
im trying to write to an sql database. im inserting an image, as well as some other information. I am using the following code which works fine, as long as i do not add an extra column/variable "LOCATION" in to the mix and leave "

commented out. *this is undesireable as im trying to add extra criteria to be saved like LOCATION.

I'm trying to run an INSERT statement to pass data from a datagrid to a table I have on my database. The problem I have is that the table has 6 columns and the datagrid has only 3. So I only want to pass those 3 columns but I get the error that the other 3 columns does not accept null values. I need to change the columns to accept null values. The other problem it is that I can't pass more than 9 records, if I have more than 9 record on the DataGrid it says "object not set as an instance of a reference" and it only add 9 records if I have more than 9.
