Visual Basic & MySQL Triggers?
Apr 12, 2010I am currently rewriting an Access application to VB. The database was already MySQL 5 with the Access application - solely used for the forms and reports. In access the MySQL database is accessed though ODBC, in VB via a .NET connector.
The problem is the following:
In the MySQL DB I have a trigger to create a UUID (or a GUID if you prefer) as a "Before Insert" trigger.With Access, the record creation works fine, and the UUID is created flawlessly.With VB, the record creation is stopped by VB when trying to insert/save the record - saying the DB requires the field UUID not to be null. Although this is right (it is mandatory in the record creation in the DB), it obviously does not take into account the MySQL trigger (and how could it?).How do you get rid of the validation for this field?

Jun 30, 2009I have a form that contains a Textbox + Three sets of radiobuttons.
my project idea is to store in any database the values selected or entered by the user.
Textbox goes Name.
First set of radiobuttons are the job position - manager - superviser etc....
Second set "" "" the Period (Shift)- day - nite
Third set "" "" The Condition - part-time - full-time
Anyway, my problem is how to insert those values into a database, something very simple such as MSAccess (is possible?)
Visual Basic Saving To A Database/Dataset
Mar 1, 2012My problem is fairly simple. What my code is doing to start with is opening the form by loading a bunch of things from a database. After all the questions are done (because it is a questionnaire) it is meant to save the current score and the username that was entered before, for the sake of programming I have hard-coded a username and score however I think because I am using a different command builder it keeps giving me the same error!
(I am studying A-Level so that might explain the simplicity of the code)

View 2 RepliesMake User Interface To A Database With Visual Basic (vs2008)?
Feb 4, 2011Write code or use tableadaptors, bindingsources, dataset, etc.? I have experience with the older ways i.e. connection strings, ado code, sql, etc. but was hoping the newer tools in vs would make the user interface easier and more flexible. So far i have been disappointed. Am I wrong and I am missing something? Am I alone in this opinion or ? What is your past experience in VB and have you found vb.net to be a step forward in db user interface design? if your answer is yes then what is the easiest way to put a table record count into a text box? should i bypass all the new stuff/objects ( adaptors, binding sources, navigators, designers, etc) and just write code or what?
