include argument name in function call, eg ?longpathname(strfile:= "c:\file~1.txt") (1 Viewer)

include argument name in function call, eg ?longpathname(strfile:= "c:\file~1.txt")

i am not sure if i am making this up or not, but i thought it was possible to include the arguement name in a function call (to improve the readability of the code).

if a function longpathname takes 1 arguement strfile then i would like to write it as something like

retval = longpathname(strfile:= "c:\file~1.txt")

obviously the function that i am using has many more arguments, hence the need to make it a bit clearer (without having to right-click and Quick Info when i want to see the syntax

I have tried all variants that i can think if - am i tripping?

Doesn't intellisense provide help when doing this?

haha...Now you have me tripping!

That is exactly what you can do providing of course strfile is indeed declared within the Function:

retval = longpathname(strfile:= "c:\file~1.txt")

is legal code and should work just fine. What error are you getting?

[boblarson]

Just curious but what are you trying to pass to longpathname?

If it is a function that returns the longpath name of the path "c:\file~1.txt" then the call would simply be:

retval = longpathname("c:\file~1.txt")

What does strfile:= have to do with it? I'm not sure what you are trying to accomplish with it. Plus the := is not typical Access VBA. It works for various things within it (for example when using Word or Excel object coding, although it isn't necessary then either), but it is not the norm for Access VBA.

i have a routine (sending outlook with loads of arguements, quite a few of which are boolean, so when you try and read the code you just see
sendmessage .......false, true, false, true etc
(I only used the filename example as it was much shorter and less confusing)


CyberLynx, cheers, you gave me enough encouragement to give it another try, and i've got it sorted now, maybe it was late when i was trying this last night!!!Not sure what i was doing wrong but it is working just fine now.

here is what i mean, here is the function definition

Public Sub SendMessage(strTo As Variant, strSubject As String, strBody As String, bolscreendump As Boolean, bolautosend As Boolean, bolSaveInOutbox As Boolean, Optional strAttachmentPath As String, Optional strCC As String)

i want to be able to call it like this, so that it is much easier to read the options when reviewing the code

SendMessage "joe@joe.com", "subject", "body text goes here", bolscreendump:=True, bolautosend:=False, bolSaveInOutbox:=False

I reckon i have worked out what the problem was - Once you specify one of the arguemennt names, eg bolscreendump, then you have to specify all the subsequent ones. You can just put the arguement name against one of them. It will not compile


i will put the code upto the repository when it is finished, should be quite useful, deals with signatures, error trapping within outlook and loads of other bits and bobs

i think you can only pass declared arguments in that way, if all the arguments are optional - otherwise you will get expected parameter errors

is that what is causing your problem

----------
eg with openform you get either (as an example - the syntax isnt right)

docmd.openform stdocname,,,,,,,true ----
docmd.openform formname: = stdocname , options:=true

 

[CyberLynx]

nikalopolis is right. If you do one ya gotta do em all.

.

 

[gemma-the-husky]

this is incorrect

if ALL trhe parameters are optional, you can just pass in selected named parameters which is what nika wanted in the first place.

They do HAVE to ALL be optional though

Key words

They do HAVE to ALL be optional though.
