Default Defining the Variables.

Hi All !!

   There is any way to define many integer in short into VB.

   Like c language and other......
   int a, b, c, d;

   instead of [ dim a as integer, b as integer, c as integer ]

   I am asking this basically to reduce the length of source ....

   Thanks in advance...:)

well.. there is a way to do that.. but I don't recommend it...

(from msdn)
Deftype Statements

Used at module level to set the defaultdata type forvariables,arguments passed to procedures, and the return type for Function and Property Get procedures whose names start with the specified characters.

DefInt letterrange[, letterrange] . . .

The letter1 and letter2 arguments specify the name range for which you can set a default data type. Each argument represents the first letter of the variable, argument, Function procedure, or Property Get procedure name and can be any letter of the alphabet. The case of letters in letterrange isn't significant.

read more in msdn ;)

The ability you describe was added to VB.NET, but not VB6 and before.

As Gonzalo said, you can define a range of beginning letters to be implicitly of a certain type, but it makes your code hard to read. There is no indication at the point of the variables declaration what type it is.

It seems really useful at first, but 2 months after you do it, you'l' be asking yourself, "What is this variable’s type?"

Don't be tempted by the dark side. . .
