SUMMARY
Moderate: Requires basic macro, coding, and interoperability skills.

This article describes how to add a record to a table each time that you print a report. This technique is useful for maintaining a print log that tracks the print history of a report.



MORE INFORMATION
The following example uses the Print event of a report to add a record to a table. The record contains the report's name and print date. The example uses the report's Activate and Deactivate events to set a global variable that is evaluated during the Print event. This prevents Print Preview from adding a new record to the history table.

NOTE: In Microsoft Access 7.0 and 97, there is one sequence of events that will create a new record in the history table when you Print Preview the report. If you open the report in Design view to view or change any of its code and then switch to Print Preview, the Activate event does not occur, and the global variable is not set. To work around this problem, after viewing or changing the report's code, close the report before you open it in Print Preview.

CAUTION: Following the steps in this example will modify the sample database Northwind.mdb (or NWIND.MDB in version 2.0 or earlier). You may want to back up the Northwind.mdb (or NWIND.MDB) file and perform these steps on a copy of the database.

Creating a History Table and a Report
 Open the sample database Northwind.mdb (or NWIND.MDB in version 2.0).  Create a table with the following structure:

     Table: tblPrintedReports --     Field Name: ID         DataType: AutoNumber (or Counter in version 2.0) Indexed: Yes (No Duplicates) Field Name: ReportName DataType: Text FieldSize: 75 Field Name: PrintDate DataType: Date/Time Format: General Date

Table Properties: tblPrintedReports ---     PrimaryKey: ID                          Create a new module and type the following lines in the Declarations section:

     Option Explicit Global Flag  Save the module as basPrintedReports, and then close it. Create an AutoReport based on the Customers table. Save the report as rptCustomers.  Open the rptCustomers report in Design view. Set the report's OnActivate property to the following event procedure:

Private Sub Report_Activate Flag = 0 End Sub </li>  Set the report's OnDeactivate property to the following event procedure:

Private Sub Report_Deactivate Flag = -1 End Sub </li>  Set the report header's OnPrint property to the following event procedure.

NOTE: You must include the report header section on the report, and its Height property must be greater than zero. However, you do not have to place any controls in the header section.

Sub ReportHeader3_Print (Cancel As Integer, PrintCount As Integer) Dim dbs As Database, rst As Recordset Set dbs = CurrentDB Set rst = dbs.OpenRecordset("tblPrintedReports") Flag = Flag + 1 ' If the current value of Flag = 1, then a hard copy of the ' report is printing, so add a new record to the history table. If Flag = 1 Then rst.AddNew rst!ReportName = "rptCustomers" rst!PrintDate = Now rst.Update Flag = 0 End If     End Sub </li> Save the rptCustomers report, and then close it.</li></ol>

Generating a History Record
<ol> Select the rptCustomers report in the Database window.</li> On the File menu, click Print to print the report.</li>  Open the tblPrintedReports table. Note that a new record shows the report name, and the date and time it was printed. For example:

<pre class="fixed_text">     ID   ReportName     PrintDate --      1   rptCustomers   8/13/96 3:25:11 PM                        </li></ol>
