Assign A Resource According To A Variable?
Apr 2, 2010I've been making this BlackJack program for a school project
I have 52 image files, labelled from '_1' to '_52' in my resources folder, each number corresponds to a card.
My question is, how do I get a picture box to assign the correct resource according to a variable
So, say I have
"pictDealerCard1" -> picture box which displays the first of the dealers card
DealerCard1 = 37 -> random number generated through INT(RND() * 52)

Assign Variable By Name Indirectly As String
Feb 16, 2011Any way to attempt to assign a variable within a data class or structure when I have the variable name as a string. Where would this be useful? Let's say I have a data class that exactly mirrors the columns of a table in a SQL database. This lets programmers easily interact with table row data as it gets passed around as an actual, specific object since Intellisense can enumerate the variables for them, etc.
However, populating such an object is tedious and repetitive--the programmer who creates the new object has to one by one match up all the members when reading from the SQL data adapter. It would be nice if they could somehow enumerate all the variables in that class and attempt to auto-assign the values from the database instead of having to build a custom population method for each new data class. A person could create a hash table or tree or something that pairs member names with actual objects.

Compiler Assign Value To Variable Even Before It Is Actually Initiated?

and my second question is that do we have this issue with C#/VB as well? (in which the ""compiler"" is free to assign a value to a variable even before the variable is fully initiated/even before the constructor function of the class of the variable is fully ran.
