MyImgClass.RGB = (255,255,255)

When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able to let it know what type of object I am trying to work with inside the arraylist. In code maybe something like this

View 4 RepliesTrying to learn VB 2005. So my questions might tend to use the logic from VBA/VB6.
So, my question is, is it possible to assign indexes on the listbox/combobox? What I have is an ID and a Description from a table and would like to display it on listbox/combobox to allow user to choose from by looking for required description. When selected the ID will be used to search for other information related to this ID.
I manage to display the description but how to assign the IDs?

I have got this error and i want to know what property access is, i have deliberately not shown the line of code that it is to do with as i do not want to be given the final answer.

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 .
