I have created an SQL query using Query Designer in VB.NET 2005. The commandtext for the query is somthing like SELECT * FROM tablename WHERE Field1=@Parameter1. I want to change this at run time to something like SELECT * FROM tablename WHERE Field1=@Parameter1 AND Field2=@Parameter2

I am using this line of code on form load event it is working very fine but i have to problems
1. It replaces the form name and display the date and time but i want to keep both date and time and forms caption separated by some space.
2. When form loads it load the current date and time but the time does not change it should run.
What should i do please please help me code is as follows
Me.Text = Date.Now.ToLongDateString & " - " & TimeOfDay
I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.

I'm trying to edit the CommandText for the Insert Command in a TableAdapter in the Designer in vb.net. Whenever I make changes to the CommandText, Visual Studio (2008) automagically changes the Parameters to a Collection consisting of one Parameter thatexisted before editing the Command, immersed in a sea of complete garbage Parameters, and then I either have to undo (unless this was the first thing I tried editing, in which case I have to close the Designer to discard changes and reopen it) or manuallychange ALL the Parameters back to something that isn't complete garbage.
View 2 Replies[Code] The above code does not work. I need for this to check to see if there is a database entry with the office name and today's date. Then if not it needs to tell the user that it is going to create a new entry for todays date. Then the code is trying to enter a new row in the database but it is like i can't use command. commandtext = in two spots. Both SQL commands work if separated but not together in this code. Obviously the abcdefghij are just test entries but it works if it is separated from the other sql command above. Also of course i have changed the datasource above to hide mine.

View 2 RepliesMy general method up until now is I use SQLClient class along with CommandText to send SQL INSERT, UPDATE, DELETE statements dorectly to the SQL Server from the VB app. I have a function I use that will escape any special characters within any string variables. I put a lot of vb database functions in a module that all of my forms can use. When I need to pass data around I send/add arguments to functions using regular variables, etc... I log all of my SQL queries sent to the server to a log file for troubleshooting.So far this has worked well. I know there are better ways to do this, Stored Procedures for example. But I just have not made that leap yet. I'm about to consider turning my world upside down!
I'm MOSTLY interested in creating custom Classes that represent the various objects in my database (Customers, Projects, Invoices, etc...). Then defining all of the properties each of these classes should have: Customer.ID, Customer.Name, Customer.Status, etc... and would like to "map" that Customer object to the database I'm interfacing with. I figure I can wrap all of the SQL commands into methods within each class, i.e.: myCustomer.Name = "Joe Smith"
