2005 with ms access 2003 batch update
View 18 RepliesI want to know is there any functions or methods that i can use to batch update the data to MS access from vb.net 2005?Here is my case:I have around 70 records to update back to MS Access.Currently I only know update row by row. So, it means i need to loop through all rows. (I also have where ...=... and ...=... and ...=... in update command.)Its not a good idea because if some where went wrong during updating.The previous updated data will be in DB but the rest will not. So, data will not correct and up-to-date.So, I want to use Batch processing. If something go wrong, all will not update. If updating is OK, then all will be in DB.

I am using VB2005. I am trying to write to an Access database seperate from the data's origin. AKA: I need to run a query getting data from one Access table and write it to a table in another Access database.
Overview: I need to get data from one Access table and two Excel worksheets. I need to write the data to an Access database so I can run a query combining the three into one table. I will then use the table to create reports.
I have googled, checked multiple sites, and checked MSDN. The only thing I have been able to find is populating a datatable and writing changes back to the database. This was SO easy in VB6.
I am writing an Automation program to control an MS Acces applcation. Here is the sequence of events:
- Load MS Access Database (Done)
- Load an MS Access form (Done)
- Take dates from Main.VB and populate 2 fields in MS Access form (done)
- Load another MS Access form called Stage_2 (Done)
- Load a file name into a filed in the Stage_2 form (Done)
- Do a click event in MS Access linked to a button called Pre_Stage_copy on Stage_2 form (How do I do these?)
- Do a click event in MS Access linked to a button called Pre_Stage_import on Stage_2 form (How do I do these?)
I have a Visual Basic 2008 Windows form application that processes some scores and data. I want to export the data to an Access database. I have created the Access database and connected it to the VB program.I am looking for a simple set of commands or sample code to add records to the database. Perhaps I am oversimplifying the problem, but it seems like it should be so much easier than it has proven to be. I only want to export the data in code; the user should never see the database or do anything to it while the program is running.

I have an MS Access 2003 database built that resides on a shared network path at the company I work for.The database works perfectly for users connected directly to the company network.However, when a user tries to open the database while connected remotely to the company network (they can still access the shared path), they receive the following error:The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.At the time that they tried it, they were the only person accessing the database.They tried a local copy as well as a copy on the network shared drive.[code]
View 4 RepliesThe Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?
