• SQL Server Transferring table data from an ODBC database to a SQL Express database

  I am a SQL newbie.  I have two connected databases that I work with in Visual Web Developer Express or Visual Basic Express.  One is an ODBC master database that contains much table data and the other is my new destination sql express database.  Where I was once very comfortable using the query grid in Access to accomplish almost anything with tables, it seems like now it is much more difficult.  Can someone offer me some simplified advice on how to easily transfer the table data in the ODBC database tables to the sql express database.  I have read sections on BCP and Bulk Insert but so far I have ...Show All

• Windows Forms DataGridView Color Picker

  Hi everyone, I've been struggling for the past 2 days to get this straight. I created a DataSet with a DataTable called "Customers". This DataTable has a few columns and one of them is named "Color" typeof(Color) (I want to use this Color later on to actually display the customer rows with the colors specified). I created a new ColorCell, ColorColumn (to host the ColorCell) and a ColorEditingControl (for edit mode). First attempt was to inherit this ColorCell from a DataGridTextBoxCell however the Value is a String type and cannot be converted to a Color type. So I thought I could trick this by hiding the old one with a new Color type like ...Show All

• Visual Studio Using MSBuild to build multiple resource assemblies in multiple directories

  I'm currently using MSBuild to build some resource-only assemblies in a group of directories. I have a directory structure that looks like this: [AppDirectory]\Resources\en-US\*.resx [AppDirectory]\Resources\en-CA\*.resx . . . Each subdirectory under Resources is named after a culture code.  What I want to do is compile all the .resx files to binary (which is easy), and then link all the compiled resource files into separate assemblies, one for each culture. So far, I can figure out how to link all the compiled resource files into one assembly, but I can't figure out how to link all the resource files in the en-US directory into an ...Show All
