Variable not found

[werder101010]

I created a global variable to define the location to save my reports: glodir = "g:\\"
I'm able to refer to the variable by just using the name �glodir� in the script: base_path = (glodir)

I prefer to use a addin.variables() to define the location to save my reports so I created autoexec script:

dim adddir as P
adddir = addin.variables()
adddir.varname = "d:\\"

and tried it with:

dim adddir as P
adddir = addin.variables()
adddir = "d:\\"

After executing the script from a form it says: variable "adddir"not found. Either the code I'm using in the autoexec script is wrong or I refer to the addin variable in a wrong way. Maybe even both?

The whole script:

topparent.commit()

if isnotblank("adm_bezwaar->Bz_F_Nr") then
tbl = table.current()

factuur = alltrim(adm_bezwaar->Bz_F_Nr)
number = alltrim(tbl.adm_nr)
client = alltrim(tbl.clientname)

'global variable works
'base_path = (glodir)

'addin variable doesn't work
base_path = (adddir)
dir_name = number+" "+client
dir_create_recurse(base_path+dir_name)


Parameter1 = eval("Bz_f_nr.value")
filter = "F_nr = [varC->parameter1]"
query.filter = replace_parameters(filter,local_variables())
query.order = ""

sav_nam = base_path+dir_name+"\\"+"factuur"+SPACE(1) +factuur+ ".pdf"
report.saveas("facturen algemeen", "PDF", query.filter, "",sav_nam)

sys_print(sav_nam)

end if

Re: Variable not found

I don't have first hand experience with addin.variables().

However, don't you want to set the scope of the adddir var to global to be able to see it outside the autoexec?

Re: Variable not found

My reading of the documentation says

dim adddir as P
adddir = addin.variables()
adddir.varname = "d:\\"

is correct followed later by

base_path = adddir.varname

Re: Variable not found

Thanks for the tips. It's working. In the script executed from the form I added :

adddir = addin.variables()
base_path = (adddir.varname)

Many thanks!

Re: Variable not found

I've used addin varaibles extensively.

To clarify what is happening:

dim adddir as P
adddir = addin.variables()

The above code defines a pointer "adddir" to the addin variable space. As yet, there is no specific variable defined in that space.

When you defined

adddir.varname = "d:\\"

you set the variable "varname" in the addin variable space to be "d:\".

Remember, the label "adddir" is just a pointer to the space.

Hope this helps.

Hi Tom H.,

I've used addin varaibles extensively.

To clarify what is happening:

dim adddir as P
adddir = addin.variables()

The above code defines a pointer "adddir" to the addin variable space. As yet, there is no specific variable defined in that space.

When you defined

adddir.varname = "d:\\"

you set the variable "varname" in the addin variable space to be "d:\".

Remember, the label "adddir" is just a pointer to the space.

This is not quite correct. The

dim adddir as P

is creating a local pointer to the addin variable space. That local pointer only exists while the current script or function is running. After that code finishes, the local variable goes away. That is why it is not available elsewhere.

However, after the pointer is created in the code, he assigns a variable

adddir.varname = "d:\\"

This creates a variable property called varname in the addin variable space. That property will still remain in the addin space, even after adddir pointer variable goes away. The addin space didn't go away, just the pointer to it.

All you need to do is later recreate another variable whenever you need it, as in

addin_space_ptr=addin.variables()

and reference the needed properties as in

x=addin_space_ptr.varname

Alternatively, one could have created a global pointer, and then the global pointer could be used, but global variables (which persist until the database application closes) and addin variables (which persist across all databases that are opened until Alpha Five closes) should only ideally be used for parameters that need to be referenced in many locations, eg. color styles, directory locations, etc.

I suggest reading my tips on variable scoping here

Ahhh. Post #2 is confirmed.
