View 8 Repliesi have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.

View 3 RepliesI am looking to produce an Excel report from an Access database table. The data contains numerous records with fields for Site, Country, Region, Type and a Resolution Time. My problem is that each month the Sites change so I need to be able to write VB code within Access to read the database table and output 'Site' records for that month, grouped together along with the incident details for that site, e.g. The report would have the following headings:
'SITE' 'COUNTRY' 'REGION' 'TYPE' 'TOTAL' 'RESOLVED<3DAYS' 'RESOLVED>3DAYS' 'NOT RESOLVED'
MEL AUS APAC TECHNICAL 78 40 31 7
MEL AUS APAC HARDWARE 49 40 8 1
LON GBR EURO HARDWARE 90 40 40 10
As I will have over 30 different sites and these may change each month how do I loop through the data identifying each site and its associated field values? I have used the following code to open the data and loop through records printing to excel, but am stuck at grouping by site:
Set rst = db.OpenRecordset(sqlStat)
row=10.......
..... Do While Not rst.EOF
.cells(row, 1).Value = rst.Fields(0)
.cells(row, 1).Value = rst.Fields(1)
.cells(row, 1).Value = rst.Fields(2)...

I'm having a problem setting the maximum number of records that can be saved into Access. The maximum allowance is to be 10. Records are being pulled from a listbox. The whole problem is that if the listbox has 7 items and my table already has 5 records, it still records them, making a total of 12. What I'm looking for is a way to trap that to a max of 10.[code]...
