VS 2008 String "" Cannot Be Converted To Type Double
Jan 21, 2012
This works fine . However , if I change the code to use the Select case statement instead of the If statement :
I get an error upon initializing the form , which says : String "" cannot be converted to type Double . Why is this happening ? The only detail I can add is that this sub is called on the CheckedChanged event of a Check box and of a Combo box . Luckily for me I thought of using the 1st code from the beginning , but on situations like these , changing from the If statement to the Select case is something that most probably won't cross someone's mind .

I'm making a card game and the first thing I'm doing for it is generating a random card. I used an array for the cards (can't think of a better way to assign a picturebox to a card picture other then a huge select case block). I'm trying to split the 2D array into two parts but it doesn't work.
My current
vb
Public Class frmMain
Private Function Flop() 'First three common cards to be displayed.
[Code].....
I looked around online and I don't think a list will work for my 2-dimensional array.

If I remove the datagridview code the 1st part of the program runs fine and works well, it is when I add in the datagridview that the error occers.

I think I am missing something really simple. I want the user to be able to select a particular interest rate and term from radio buttons (in separate groups), the values for the buttons are to be stored in an array. Then they click the calculate button and it does it's magic and pops the result in to another field. I think I have things set up roughly the way it needs to. What I'm running in to right now is the term variable in the calculation formula is coming up with a blue underline stating that "value of type -1 dimensional array of double cannot be converted to a double". So as a result nothing is working right. I don't know where exactly I've gone wrong. If I change the data types nothing seems to change.

last.Remove(last - 2)
End If
But it gave me the following error on the highlighted line:
"The converting from the string to the type Double is not valid."

I can see this SP from VS 2008 in the Server Explorer. So the problem seems to be that I don't know how to connect a data adapter to an SP. Just a string query.

[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
