• SQL Server INSERT Not Working via Emulator SmartPhone WM 5.0

  It would be great to get some feedback on this, I've wasted nearly the whole day trying to figure it out. I've created a simple test database called test.sdf. It contains a few tables but no data. My plan is to populate the database programatically; however, the INSERT command does not seem to be working correctly. I can see that the data actually gets added to the database when I add it and iterate over it programatically (using SqlCeCommands), but after the program completes and I look at the Table in "Server Explorer" via VS 2005, the data is no longer there! Now note that the location of the sdf is in the Emulator's " ...Show All

• Visual Studio Express Editions Selecting from a Combo Box

  I have a combo box with 5 pre-defined items. When I execute my code, no matter which item I select from the drop-down, the code always executes the first selection. cbxLength contains the values 10, 15, 20, 25, 30 which represents the # of years, and I multiple their selection by 12 to calculate the number of months. Why is the code always selection (0) as the index Thanks for any help you can provide. If cbxLength.Items(0) Then NumberPayment = 10 * 12 ElseIf cbxLength.Items(1) Then NumberPayment = 15 * 12 ElseIf cbxLength.Items(2) Then NumberPayment = 20 * 12 ElseIf cbxLength.Items(3) Then Nu ...Show All

• SQL Server Get FlatFile Columns through ConnectionManager

  The CreatePackage sample provided with SQL Server programmatically creates a package that has a source type of OLEDB to a flat file destination. I am building exactly the opposite, source=flatfile, destination=SQL Server. I expect that will be a more common scenario is using SSIS. The problem I have is populating the source columns in the FlatFileSource connection manager programmatically. I know it can be done because it happens when you build a package in Visual Studio. What I'd like to know is how to do it programmatically in the object model. How can I interrogate the datasource through the connection manager to find out what columns ...Show All

• Visual C# MySql error: should be string, but is seen as double

  Hello, I've been getting errors with MySqlParameters and the execution of the query. I want to insert program-names into a database, but these names mostly contain a dot e.g. 'program.exe'. When adding the name by using the MySqlParameter, it apparently converts it to a double because of the dot in the name. I tried specifying the DbType as DbType.String, but it still sees it as a double. Here are some code-snippets: /* the query-class is a shell for the MySqlCommand, the constructor sets the query itself, the rest is set in the class itself. There's a method to add parameters: AddParam(MySqlParameter param). */ this.insertQuery = new Quer ...Show All
