View 1 RepliesSummarize And Group Access Data Records In Excel Report
May 25, 2009I 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)...

Auto-generate - Updating Function - Hospital System Which Works With A Access Database ?
Jun 21, 2010I am using vb to make a hospital system which works with a access database. i am having an issue with the updating function to the database, this time round instead of hard codding the connection i used the connection/data source wizard, in microsoft visual studio 2008 and there fore most of the code has been auto generated for me, which includes the insert, delete and update funtions from what i can find and what i have read vb is ment to also auto generate this which it is not. the funny thing is that i can close the program down and reload it (as long as i haven't opened the database) and my changes are still there but if i go and open the database and it hasn't changed. also i can change the database through the use of the Dataset connections in the datasource tab but not int he program the code ive found and believe that is meant to update the database
This is running off a couple of buttons i also have a update query but have know way of accessing it
Me.Validate()
Me.TblPatientDetailsBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.PatientInfoDataSet)
