View 13 RepliesChecks For Duplicates Before Insertion?
Jan 16, 2012Im confused on how to write a code on checking duplicates before insertion on vb.net. I know the sequence on how to do it but its kinda confusing when writing a code.
1.) Create a query that will check if the mobile number already exists on the database
2.) If not, insert the new data
3.) Else, a message will prompt that "You are already registered".
writing this in PHP is kinda easy for me but in vb.net.. , unfortunately, not easy.. Im still a beginner on vb.net.

Dynamic Insertion Of Textboxes?
May 12, 2011I've been trying to learn enough to develop the family tree diagram and making progress.[URL]..It illustrates many of the drawing, saving, re-opening, editing, drag/drop features that the family tree diagram would need, and is a good starting point.
To adapt this for the project, after searching for snippets online, I've tried to add dynamic insertion of a label as a start (eventually, it should be a textbox that the user, in runtime, can enter text into, save, re-open, edit). But, I can't get this to work. No errors display, but I must be doing something wrong.
Here's the label code which I've so far appended at the end:

View 2 RepliesC# - Insertion Of Nullable Types Into Database
Aug 24, 2011I have recently been working on a number of sections of code that deal with the insertion of Nullable types into a database. As I'm sure anyone who has dealt with similar code will be aware of the annoyance of constantly writing conditional logic to deal with the insertion of nulls into a database. I.e.:
MyValue.HasValue ? MyValue.Value : DBNull.Value;
If(MyValue.HasValue, MyValue.Value, DBNull.Value)
Basically I am just wondering why DBNull.Value exists and why Null simply couldn't be used?

Verify Record Insertion Using ExecuteNonQuery?
Jan 2, 2007I'm using parameters on a SQL stored procedure to insert a record with data entered on a website form (and on the form I'm using VB.net). As of right now, the form works perfectly; the record is inserted. However, after the user hits the submit button, everything executes and then the page will basically refresh with emtpy values in all the fields. So I want to give the user some type of SUCCESS message, assuring the user the information was successfully entered into the database. So my question is: How can I verify that the record insertion was successful? I want to do this with the ExecuteNonQuery statement, because that's what I'm using.
Code is below:
If Page.IsValid then
Dim MyConn as SQLConnection= New SQLConnection("Blah")
Dim MySQL As SQLCommand
MySQL= New SqlCommand("proc_newWebEntry", MyConn)
MySQL.CommandType = CommandType.StoredProcedure
