Getting sub or function name, programmatically

[cappy2112]

In vb6, Is there a programmatic way of getting the current sub or function name, similar to a form name

that is ...

the name of a form can be found by Me.Name.


Is there an equivalent for a sub or function ..

sub AddTotal(x as integer, y as integer)

' body of sub

msg="An error ocurred in" & sub.name
msgbox msg

end sub

Obviously, this syntax doesn't work, sub.name,
it's just an example.

You could declare a module or global level variable that will hold the name of the current sub/func. So each sub/func appears to have this name assignment as the first statement in the code.

If you have to assign the name of the sub or function manually to the global variable that you mentioned, in each sub or function, that defeats the whole purpose of the idea- right ??

The idea is to get the name of the sub/function without having to type in each sub/function name.

If your program has 600 functions, then you have to go through each function and type GlobalNameVar="MyFunc". That approach is pointless.

If VB has the feature where you can acquire the sub/function name using some built-in variable (ie.. me.name-> sub.name, or func.name) then you can add some error handling and logging code that is exaclty the same for each sub or function.

So- at this point, I still don't know if VB has a mechanism to get access to the current sub or function name.

Who made this thread a 5 star rating?

And what criteria was used for the rating?

At this point all of it sounds pointless to me, since all you have to do is make it a public function or sub in order for Me. to have access to it.

I *may* have clicked on the rating- accidentally. THe wesbite was very slow, and not responding, or the browser was messed up.
It wasn't my intention to rate this thread at all. Feel free to unrate it.

me.myfunc() doesn't give you programmatic to the "name" (in a string) of the function, only it's address.


function MyFunc()

On Error GoTo global_error
WriteToExecutionLogfile "MyFunc()"
#End If
Exit function

' body of the function is here


' body of the function is here

global_error:
WriteToErrorLogfile "Global Error ocurred in MyFunc", me.name
End


Do you see the 2 strings "MyFunc()", and "Global Error ocurred in MyFunc" ?

Is there a mechanism to get the NAME of the current function (or sub), WITHOUT having to type in the name of each function, manually?

The lines containing WriteToExecutionLogfile() and WriteToErrorLogfilesubs, can be added to every function/sub using search and replace in an editor, if the function name can be accessed as a string.

If not, one would have to go through every sub/function and type in the name manually. We would rather avoid that if possible, because we do want to use the Execution and Error logging features above.

No.. there is no way.

In other languages like C# it is easiy, but it is simply not possible on VB. I searched long time for a solution because I had a quite big app that used a Audit Engine and I wanted to know what Function called the error.. but I gave up after about 2 months of searching docs and MSDN

Well, that's not an idea rather a problem in which you are trying to find a solution.. And that's the only solution I can think of.. I did not say that you insert this statement manually, you can create a service program that could do this for you for 600 functions.. Goodluck!

hi,

if i understand your code correct, you only need the function
name in itself, so you can maybe try this: create one class module
(i've called mine FunctionFactory) and within you'll have one private global variable holding the function name and just two properties Get and Set like this:

Private m_InternalClassName As String

Property Get sInternalFuncName() As String
    sInternalFuncName = m_InternalClassName
End Property

Property Let sInternalFuncName(strName As String)
    m_InternalClassName = strName
End Property

and in your main code/function in your function body at the very
beginning of the function you set the internal function name and then at e.g. line 1000 use classfunctionfactory.sInternalFuncName to get the function name:

Option Explicit
Private ff As New FunctionFactory

Private Function myfunc1() As Boolean
    ff.sInternalFuncName = "function 1"
    'code code
    Debug.Print "call from: "; ff.sInternalFuncName
End Function

Private Function myfunc2() As Boolean
    ff.sInternalFuncName = "function 2"
    'code code
    Debug.Print "call from: "; ff.sInternalFuncName
End Function

Private Sub Form_click()
    myfunc1
    myfunc1
    myfunc2
    myfunc1
    myfunc2
    myfunc2
    myfunc1
End Sub

hope this helps,

Thanks, but actually your approach is what I want to avoid.

SInce the application is very large, I would have to assign the name of each sub or function to the variable.

I'm trying to avoid doing this, but VB doesn't have a built in feature like Python does, to get the function name, as a string, automatically (without having to manually enter the function name).

If all you are trying to do is avoid manually typing the names of Subs and Functions, one solution might be to save your code as a .txt file and then write yourself a small read/parse sub/function that will assign each of the names to an array which you could then access in your code. Quite simple really.

i don't see a difference between
Me.Name and object.sFunctionName
also there is a difference with your hardcoded string (e.g. "MyFunc"), since you don't need to remember the name of your function on the 1000th line of your code and you don't need to search every time you change your function name. i think the effort is smaller, than parse a file with function names ;-)

kind of regards,
