• .NET Development Data Access Layer - Design

  Hi I have been reading a few of the recent tutrials on 3 tier design (Data/Business/Presentation). In My database i have a customers table, employee tabel, supplier table and an address table which has either a customer, employee or supplier foreign key. In these tutorials it says that each database able should only be access by 1 data access layer class. If this is true then how is it possible with this database stucture, for example my Orders DAL needs to know about an address because each order has a billing, and send to address. But also my Customer DAL needs to know about address as each customer can have many address's Thanks lee Hi jshelper So these clases you have made here are these your DAL classes or your BL ...Show All

• Visual Studio Express Editions Filtering a datagridview with more than one criteria

  I have a datagridview with 4 columns that I need to filter based on 4 textboxes on another form. The following is code that works using just one of the text boxes: CatalogBindingSource.Filter = String .Format( "Year='{0}'" , Tracking_List.Year.Text) My question is, what is the correct format to include the 3 other textboxes (called Make, CardNumber, and Condition) so the datagridview is filtered based on Textbox1 AND Textbox2 AND Textbox3 AND Textbox4 The names of the other columns in the datagridview are the same as the textbox names on the Tracking_List form. Thanks, John Thank you! Worked perfectly! I knew I needed the 'And' operator, but I didn't know the exact syntax of the en ...Show All

• Visual Basic designer.vb file not associated with vb file it is a partial class for.

  I couldn't find the general Visual Studio forum... My application runs fine in Visual Studio after creating a new solution but when I open up Mainform.vb the controls aren't showing up on the form. I normally see the plus sign for the Mainform.vb and then when I expand it, I can see Mainform.designer.vb and Mainform.resx under it. Not sure what happened in this transition process from one solution to another. Here is what I did. Before checking a solution into SourceSafe I wanted to clean it up and get rid of unneccessary files and projects used in prototyping. I created a new Windows Forms Project. In the folder created under Documents and Settings\Visual Studio 2005\ Projects\New Project, I pasted into that folder all the fil ...Show All
