Updating records in a dataset vb net Free xxx adult dating in nairobi
NET, I wrote this piece of code to extend Microsoft’s example of a simple parent-child relationship.The function Update Data Set can accept as input an array of tables and their corresponding data adapters, perform all requested CRUD operations and return the dataset with rows having 'as expected' row state and version for merging back to client's datasets.
I'm having difficulty getting past the idea of how to update a record in a Microsoft Access 2000 database file. OLEDB.4.0; Data Source=|Data Directory|\bin\MY_DATABASE.mdb" con. Open() sql = "SELECT * FROM client WHERE ID = 1" da = New Ole Db. I want the update method to work like that of the code snippet I provided above, or atleast something similar to that. The error report which I get, is as follows: Project1.has encountered a problem and needs to close. Do you perphaps know what might cause this error report whenever I click the update button?
I have no problems inserting, deleting and creating new records in the database, but somehow it seems that there's more to updating a record than what i had expected.
