vb.net - Operator '=' is not defined for types 'Integer' and 'IQueryable(Of Integer)' -


This is giving me a headache I have this link query that holds an ID 

  Moderate mclassID = x to db.SchoolClasses where x.VisitDateID = _visitdateID select x.ClassID

and then later I have this liner query

< P> ViewData ("Staff") = T to DB. Staffs where choose t.ClassID = mclassID

Any help would be greatly appreciated I have tried a lot, but I have not used any kind of casting, converting, ops Tried End etc.

The problem is that myClassID is an unknown IQueryable . You need to force it in any other type ( list my favorite), and then drag it out of that way So if you select it in the list (of integer), then you can remove before () , because it will be only one, you can try something like this: / P> 

  Due to myClassIDList list (of integer) = new list (of integer) (_ to x db.SchoolClasses in where x.VisitDateID = _visitdateID select x.ClassID) as dim myClassID Integer = myClassIDList.First ()

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
