Comparing Array Index To Combo Box Index?

Nov 14, 2010

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

How To Map A Combo Box Value To It's Index

Jul 9, 2009

I have DataSet "ds", that has a table with two columns and 11 rows. First columns is "ID" second column "name". I need to fill a combo box, with all teh names in "name" column. This i can do with

foreach(DataRow d as ds.Tables[0].Rows){ cmbBox.Items.add(d.ToString());}

But i need to map each name in the combo box to it's "ID" (in the table). Assume ID = 10000 has the name = "Mark", then if the user selects "Mark", i can store it's "ID" 1000 to a variable. How do i map the "ID" to "Name"?PS: Appologies for C# code !

DataGridView Index - Index Was Out Of Range?

Apr 14, 2009

I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?
