VS 2008 Cannot Read Integer As Primary Key To Save To Database

Nov 13, 2009

I'm using Visual Studio 2008 and MS Access 2007.

I have linked the database to vs2008.

The first problem I have now is how to add all the data to the combobox from access 2007? [I have solved this myself accidentally.]

The second problem I have is I cannot save the primary key.

Assume that I have these:
Table name: tCustomer
ID Datatype [Text]


Now, the user fills in the form. The ID cannot be edited by them where it's automatically counts the number of customer in database and give the id. For example, I already have 3 customers in the database so when I add new Customer, it will be 4 for the ID.

When I click save, it shows me the message of "Index or primary key cannot contain a Null value." I have set an input mask for my Customer. So, can I make it to save in a format like CT001, CT002, CT003 automatically?

VS 2008 Save Image To MySQL Database?

Mar 9, 2011

This has really been a problem for me in the past and with deadlines, we decided to just have the app copy the image to the server, rename it and save the link in the database. This is the worst way of saving that kind of sensitive data, I know. We now have the time to fix that.

Error When Getting A Substring Of X Characters Out Of A Parent String Of Less Than X Characters?

Feb 23, 2011

Not sure if too many people know this, but the following line will cause an error:

GroupName.Substring(0, 3) = "jt_"

....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:

If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then

Note that the two comparisons need to be on separate lines. If they are on the same line, such as:

If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

VS 2008 Make MySQL/DataTable Handle Norwegian Characters?

Oct 4, 2009

I'm populating a DataTable from a MySQL-server. One of the columns contains norwegian characters (�, �, �), but they don't display correct in my datatable. I've been searching google for some answer, but I haven't found any. I've never had this problem before. Actually I'm not quite sure exactly where the problem is. It's either in the datatable or in the MySQL .NET-connector as far as I can tell. If I do the same query in the MySQL Query Browser, the characters are shown correctly, so it can't be the server.
