Feb 10, 2010I need to take 6 user entered dates and compare them to a date pulled from a database & stored in a variable. If greater than 6 weeks, then some action needs to take place.When writing the code, I get the following message (before compilation). Value of type 'Date' cannot be converted to 'System.TimeSpan'. [code] Within my code the 'dt' in the line above is underlined with the error message appearing on mouseover. I have tried using CType, as in dt = CType(Session("dt_occurence"), DateTime) in the hopes that might work, but it doesn't do it.

.net - Why Is Date1.CompareTo(Date2) > 0 Faster Than Date1 > Date2
Aug 6, 2010Unimportant because mostly code-readability is much more important than a few milliseconds, but interesting anyway.I noticed that there are differences between different DateTime Comparisons.I checked 3 alternatives:
Dim clock As New System.Diagnostics.Stopwatch
Dim t1, t2, t3 As Long
Dim Date1 As Date = Date.Now.AddSeconds(2), Date2 As Date = Date.Now
[code]....
Normally i choose first method because it is more readable and fail-safer than the others.Method 3 is the fastest. Is this the method that the compiler would choose when i use the operator overloaded method 1? When yes, why are there differences during runtime?Method 2 is the slowest, maybe because it is shared/static?!UPDATE: added some more values. Now Metod 1 and 2 are pretty equal fast.

Value Of Type -1 Dimensional Array Of Double Cannot Be Converted
May 6, 2012I think I am missing something really simple. I want the user to be able to select a particular interest rate and term from radio buttons (in separate groups), the values for the buttons are to be stored in an array. Then they click the calculate button and it does it's magic and pops the result in to another field. I think I have things set up roughly the way it needs to. What I'm running in to right now is the term variable in the calculation formula is coming up with a blue underline stating that "value of type -1 dimensional array of double cannot be converted to a double". So as a result nothing is working right. I don't know where exactly I've gone wrong. If I change the data types nothing seems to change.

Error: Value Of Type Cannot Be Converted To 1 Dimensional Array Of String
Sep 29, 2008[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
