View 6 RepliesI am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.

I think I'm getting hung up on syntax here. I've got 2 forms and am trying to pass a textbox value from the 1st form to the 2nd. The textbox value is an unique ID #, so it's an integer value in the database. The ID displays in the textbox just fine on the 1st form. When I try to access the value of this ID textbox in code in the 2nd form, I see that the value is empty, or equal to "". But I see a valid ID # on the 1st form. Here's the code that shows me that the textbox equals "".

I tried couple of ways but nothing seems to work correctly.
I'm pulling up a a webpage in a control and the page is full of Java functions. I'm able to use execute a function using invokescript. That works out really well. But here's the thing. There's a function that takes the value of a rendered textbox and uses that data to perform the function.The textbox is usually hidden until another function activates it to enter data.What I want to do is to bypass having the textbox come up and execute the function with predefined data. Basically the function refers to the data it gets as txtWrapupComment.value whereas txtWrapupComment is the textbox it's getting its data from.
So, the bottom line, is there a way I can declare txtWrapupComment.value and pass it before I execute the funtion?
basically, i get "Object reference not set to an instance of an object" on the line:
example Dim x As Integer = objPlayer.Hand.Count
this line is in the object Dealer, but as far as i can tell i've declared everything correctly ...
i was told that i had to pass the values to the object or something, but not how to do it

View 1 RepliesMy problem is that I have two forms, Form1 and Form2 ...on Form1 there is a TextBox called txtTotal (this contains the calculation of Ticket Prices, thus it's a numeric value) and on Form2 there is a TextBox called txtTotal2. All I want to do is get the same number that appears in txtTotal on Form1 to appear in txtTotal2 on Form2 .However whenever I try some of the help tips online such as using a declaring txtTotal as global or friend it dosn't work, and any other code iv tried attempts pass the textbox value as String which brings an error.
