I've got to ask, what is the perceived benefit to you by forcing this requirement? -- Mike

I have some dynamic validation dlls that I load from the db. The idea is basically, read the dll file into a byte array and then call assembly.load with the byte array. So, I would do something like this for a dll... Dim dllData() As Byte = File.ReadAllBytes("pathtodll") Dim dllAssembly As Assembly = Assembly.Load (dllData) once you have that assembly reference, you can laod types out of it etc. for instance, I have a dll that defines common interfaces/base classes that are referenced by the individual validator dlls and the parent assembly - that way there is a known means of communication (Air-Code)... Dim validator As FAValidatorBase = TryCast (dllAssembly.CreateInstance (validatorInfo.ClassName), FAValidatorBase) If validator Is Nothing Then Throw New FAValidatorLoadException(validatorInfo.ClassName) Dim validationResults As FAValidationResults = validator.PerformValidation(inputData) So, the question is do you have access to the dll's data and can you read it into a byte array :) -- Tom Shelton |
