VB.Net VB6.Format() Issues after converting

Question

Having some issues after running a tool to convert the VB6.Format() to VS 2008 code. We had this statement:

VB6.Format(InVariable, szFormatMask))

That was converted to this:

InVariable.ToString(szFormatMask)

The issue being that now, when we call our function it has having the issue that it cannot convert a String = "" to an Integer value. InVariable is an object, and szFormatMask is a string in our function. Do you have any suggestions as to not cause this issue any longer?

What is the exact type of `InVariable`? (so even though it's cast as an `System.Object`, what is it really?) — Dai, Jul 17 '13 at 19:38
In this instance, it is a double being sent to the function. — user2178477, Jul 17 '13 at 19:42

Add a check for the empty string and change accordingly:

If szFormatMask = "" Then szFormatMask = "G"
Return InVariable.ToString( szFormatMask )

The 'G' format-string value is special in that is specifies the output is the "General" number format.

(A brief word on code-style: please avoid Hungarian notation, e.g. the In and sz prefixes, and name local variables and parameters using lowercase camelCase, as uppercase CamelCase is reserved for type members like methods and properties.

Now, I am getting Conversion from type "G" to type Integer exception is not valid. — user2178477, Jul 17 '13 at 20:17
