May 13, 2009I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:
Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer

Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id

I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

VS 2010 Conversion From String "" To Type 'Integer' Is Not Valid
Jun 17, 2011I have a random generator with a textbox where the user selects the number of randoms they want from a text file that is loaded into a listbox. I want some code to prevent the user from trying to randomly generate more items than what they entered in the text file. I have a messagebox that informs them they entered a higher number than what is in the file, which appears to work until I hit the backspace key to change the number in the textbox. Then I get this error. "Conversion from string "" to type 'Integer' is not valid." I currently have the code in the textbox, text_changed event, not sure if this is the right place. Basically what I want to do is have the message box pop up to inform the user, then reset the textbox back to empty so the user can choose a new number. I already have a textbox keypress event to only accept numbers, no letters. Not sure if I can combine the code to do both.
