View 9 RepliesI have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

View 1 RepliesI have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)

The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
