View 14 RepliesfrmAddUser is a simple form that is opened as a dialog by a command button on the primary form (frmPrimary). Once opened, it's only job is to collect information via textbox and combobox fields. Once submitted, the information is added to the database.
This works, or so I thought. If I open this form, fill it out, and submit the information; the record is created. However, if I turn around and do it all again with different information, another record is created but with the previous information (not the new). It will continue to make records as long as I keep submitted this form but no matter what information I put in, it always uses the original information that was used to create the first record.[code]...

View 2 RepliesI am creating a windows program with VB and an Access database. I have a list view that displays on column in the database and I have that working due to the table adapters in VB.

I am having the hardest time and can't seem to figure out how to use custom sql statements manually in

What I want is to make a custom file with my program. This file we will pretend is called InfiniteMapFile.INMP and the file has no contents therefore we need to add contents. There are 3 pixture boxes and 3 text files. The data for each of these files needs to go into InfiniteMapFile.INMP with the associated names, then later on be taken out if needed. Here is a diagram:
you can see what I mean by putting the files within it, I would have made my file look more like a box, but we're not 5 years old and I'm sure all of you will understand.Just knowing how to combine multiple files in general will help.
