View 1 RepliesI have been tasked with writing a program for our yearly reviews. We want all of the information gathered in the form to be submitted to an access database. I have created the form and the database. I can send info to the database but it is put on a new line everytime it is submitted. I would like to check the first column of the table to see if the user login is already there. If it is there I would like to update the information. If it is not there I would like to create a new row. This seems simple, but I can not figure out how to see if the user login is already there.[code]...

View 1 Repliesusing visual studio 2010. I have a vb.net application that needs to be updated periodically. The software stores client lists in a database for the user, but when the user reinstalls the program after I send them an updated publish, the client list database is replaced with a fresh empty database.
Is there a way that the user can reinstall the software without losing their current database?
I don't know if I need to somehow make separate publishes. One for an initial install to set up the database, and then one for updates that leaves the client database untouched? I don't know how to go about it.

How to update a record database table from unbound datagridview using vb.net
View 7 RepliesI have a bindingsource question, didn't know if anyone had run into this before, but,there are several textboxes I put on a form, the text of each textbox is bound to a field in a table from the bindingsource. Why is it when I update the tableadapter, some of the fields update and some of them don't?
Example:
using the bindingsource
Textbox1.Text is bound to UnitListBindingSource - UnitNumber
[code].....
Assume my form has four text boxes and it's bond with a Dataset, therefore The user can 1-4 fields. Typically I write one update statement that take four input parameters. Therefore I update the updated fields as well as non updated field. To do this in the proper way, how many update statements I have to write?
Or
How do I do this update properly? I use SQL server 2K5
Public Function ChangeUpdateOrderPlace() As Boolean
' Try

I've been running into some errors with converting strings to dates in the following code. I have recently added the intcall.Value = DateTime.Parse(txtIntCallDate.Text) function which had gotten rid of the error message, however the records are not being updated, any of them on the form. Prior to this the strings were being updated just fine. As long as there is a date entered on the form there is no error, if it's left blank i get the "Problem converting string to datetime"

I am making a booking system. I am using same form for insertion and updation. How can I update by taking the values from the textboxes. For example if the user enters value for just 2 out of 8 fields then How can i update just 2 fields without affecting the rest of the record. I mean to say that if I use a single update query using all the fields then if some textbox is left empty then it will replace the database field value by null or something else.
