Code Written In C# - Conversion Of Csharp To VS2005
Jul 3, 2009I have some code that was written in C# and am attempting to convert it to VB.Net, for the most part things have gone well but I am running into an issue that I am not sure how to handle. The project has several classes and a few namespaces defined. The issue is [or seems to be] related to the namespace usage.
In the C# code of one class I have
Code:
namespace GdiPlusLib
In another class I have
Code:
using GdiPlusLib;
When translated to VB I have in the first class above
Code:
Namespace GdiPlusLib
and the following in the other class from above.
Code:
Imports GdiPlusLib
I get the following warning message on the imports line
Namespace or type specified in the Imports 'GdiPlusLib' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. There is another instance with a different namespace that gives the same warning and I get 11 errors all of which would seem to be related to the two warnings.

Error: Option Strict On Disallows Operands Of Type Object For Operator '='. Use The 'Is' Operator To Test For Object Identity
Jan 27, 2010I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:
If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then
It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.
Option Strict On Disallows Operands Of Type Object For Operator Use The 'Is' Operator To Test For Object Identity
Apr 6, 2012I need to write an interface to get data to/from our data files.
We have a low level class that holds field values for each record read from the files.
This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).
These values may be any of the standard value types (integer, date etc) or a string.
Either value (DBValue or CurrentValue) may be null if not defined.
I have written the class to manage this data which works fine while option strict is NOT on.
But we have an office policy of having option strict on all the time.
When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."
Question, how should I change the following code to handle option strict on ...
This is all running on Visual Studio 2010

View 8 RepliesThe Given Key Was Not Present In The Dictionary. - Enumeration?
Aug 15, 2011I've been getting the following error from time to time and have been unable to determine the cause of it:"The given key was not present in the dictionary."The line that this is occurring on is:If CType(ViewState("FieldType"), MYClass.FieldType) = MYClass.FieldType.ShowOnDirectory ThenI have no idea as to why it is throwing this exception on this line. I thought that perhaps an invalid value was being placed in the ViewState so I tried while debugging setting the value to Nothing and setting it to a value that wasn't in the enumeration and it still works. I was originally storing the enumeration in ViewState and then went to storing just the Integer equivalent in there

Is there any way to make the button selectable only by mouse click?
