Actually this is vb6 to .net converted code. I m getting compile error at following line
temp = Lset(DispElem(i)) bcz Lset is not supported in .Net Lset accept string data type for first parameter and interger for second.If you know any alternet solution or if you have any source code for Explicit convert UDT to string type and vice versa.

It's supposed to represent a value of degrees from 0 to 359.

I am in the process of migrating from VB6 to VB 2008. In a pixel grid system I have thousands of cells with about 15 properties each. In VB6 I employed the user-defined datatype "udtCell()" as my array structure. Is this still a good approach - or should I perhaps make Cell a class?

I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]

View 3 RepliesTo correct this error I use the given help that microsoft provides below and i am still getting the error messages can anyone assist me with the source codes if i send some code snippets?Check that the type definition and its reference both use the same spelling.
Check that the type definition is accessible to the reference. For example, if the type is in another module and has been declared Private, move the type definition to the referencing module or declare it Public.If the type is defined, but the object library or type library in which it is defined is not registered in Visual Basic, click Add Reference on the Project menu, and then select the appropriate object library or type library.
