new to excel macros

[kmm1977]

Hi
have programmed with C++,Java and am new to macros in excel

i have a project for which i have to write a design ( code already there )

since i am not used to VBA syntax i am not able to catch the head or tail of the application

my questions:

1) Thisworkbook - is this some sort of main

2) Modules - contains Functions , is there any structure when we write excel macros ?

or is it only Functions inside Modules

3) what are classmodules ?

4) when i start the macro , where does the program begin ?

regards

"thisworksbook" means the workbook in which the macro is parked.
functions are different from macros

macros are programmes to do something.

function is something like a formula. for e.g when you use sum(A!:A%) there is already an embedded function in excel

when you run a macro the programme starts at the first executable statement

e.g.
sub test
dim r as range, j as integer, x as string
worksheets("sheet1").activate
...
end sub

the programme starts with "worksheets("sheet1").activate" though it keeps the dim statements in the memory

You can get a good book excel macros.

KMM the syntax is a little bizarre if you're used to C. I'm just now starting to get more in tune with VBA syntax and my background is some basic C so maybe I can help clear things up a little.

Functions are pretty much the same in C as they are in excel, with one exception.

In C, you'd name your function and as long as it wasn't a void function, you'd have something like return VariableName; at the end. but in vba, the function name itself is the variable that is returned. For example:

Long MyPCT(Long Retail, Long Wholesale)
{
long percentage = Retail / Wholesale -1;
return percentage;
}

Function MyPCT(Retail As Long, Wholesale As Long)
    MyPCT = Retail / Wholesale - 1
End Function

In C, your line could wrap as much as you want until your semicolon, but in excel, a new line is the end of the code so you'd have to manually extend your code with a _.

Excel also uses objects (which I'm not good at so someone else will have to fill in this gap), but I'd equate them to structs in C.

So far the two things in VBA that I don't like is the inability to comment out code blocks using /* and */ but rather you need to use the mouse. VBA also doesn't have an increment or decrement operator (++ and -- respectively).

Those are a few of the thigns I noticed, there's some trial and error but hope that helps at least a little.

thanx for the replies , i checked most of the sites you mentioned but did not find answer w.r.t to program structure

i do understand what a function can do etc.

but i did not understand

1) modules , are they similar to packages in java ?

2) what are class modules

regards
