Need help with trimming a specific count or number of characters

[rcolbert]

I have a script that I am picking a path of a file and placing the variable in a field for later retrieval. I have the server and good portion of the path stored in a separate variable table just in case the location of the images changed or something. I want to pick the path into a variable and then subtract the matching portion of the path from what I just picked. I am thinking I can use len(field) to get the length of the path variable but there is where I am not finding a command.

Please post some examples of what you start with and what you want to end up with.

And a description of your thought process.

Agree with Al. You're short on details.

Maybe you want

path_variable = "C:\temp\images\testjpg.jpg"

? file.filename_parse(path_variable,"D")
= "C:"
? file.filename_parse(path_variable,"DP")
= "C:\temp\images\"
? file.filename_parse(path_variable,"N")
= "testjpg"
? file.filename_parse(path_variable,"NE")
= "testjpg.jpg"
? file.filename_parse(path_variable,"DPNE")
= "C:\temp\images\testjpg.jpg"

Re: Need help with trimming a specific count or number of characters

Okay... lets try this.

picked_path_var = "\\server\folder1\folder2\folder3\folder4\folder5\filename.ext"

system_var = "\\server\folder1\folder2\folder3\folder4\"

I want to accept picked_path_var and remove only the part that matches exactly that is in the system_var variable. So in short subtract system_var from picked_path_var and the result to be only:

folder5\filename.ext


That is all I want to store with the accompanying info so if in the future we change servers or whatever I can simply change the the system_var and the images will work from the new location.

Hope that helps.

Re: Need help with trimming a specific count or number of characters

On paper it looks right but below is the expression that I built and the result it returns to me is simply the "picked_path_var"

I my script the "pickled_path_var" is GETFIL and the "system_var" is PATH

'Set 'Value' property of 'Path' in Form 'sys' .
DIM form_name as c
if is_object(topparent.this) then
form_name = topparent.name()+".this"
else
form_name = ""
end if

DELETE expression_result
expression_result = eval("STRTRAN(Var->GETFIL,Var->PATH,'')",form_name)
parentform:Path.value = expression_result

THANK YOU SO MUCH FOR YOUR HELP.

Re: Need help with trimming a specific count or number of characters

It looks like maybe GETFIL and PATH are objects (text boxes ?) in your form. Is that right? If so, you're retrieving the values from the text boxes incorrectly.

expression_result = STRTRAN(parentform:GETFIL.TEXT, parentform:PATH.TEXT,"")

[rcolbert]

Re: Need help with trimming a specific count or number of characters

GETFIL is acquired with the "prompt for Filename" action that I have added before this script.
PATH is acquired using the "get Fild Values (into variables) action.

should I be using something else?

In pasting the line above into the script is said it could not find any of the variables. (GETFIL or PATH)

Again, thanks so much for your help.

Re: Need help with trimming a specific count or number of characters

Sorry. I assumed you were showing us the entire script. But you did not. So, I guessed wrong.

When you select the filename what does GETFIL contain? in post 7 you said it contained "pickled_path_var".
When you specify a field and retrieve its value into PATH, what does PATH contain? in post 7 you said it contained "system_var".

Color me confused.

Re: Need help with trimming a specific count or number of characters

This whole thing is to tie pdf images to a 14 field database.
GETFIL contains the entire front to back, side to side path where the image is stored in a "UNC" format.
When I push a button it activates a form that has the PATH variable and it stores that variable.
It then prompts with a browse window so I can browse to the location of the pdf image. When I click on it it stores GETFIL value.
I then simply need to subtract the PATH variable value from the GETFIL variable value because between the 2 there would be redundancy if I don't remove path. I need to remove the PATH because I need to keep the server path in a variable in the event we want to move the images to another server or location so none of the database has full path hard coded.

I hope this explains better.

I went in and modified my profile. I am very new to the forum, not new to Alpha but not anywhere as good and many of the users her.

Re: Need help with trimming a specific count or number of characters

GETFIL is "picked_path_var" and "system_var" is PATH. In my initial explanation I tried to make is easy and in my attempt I think I made it confusing.

Three lines:
Define your default server folder (path)

syspath= "C:\Users\Ray\Downloads\"  '** change this to your own default server folder name

Make the file selection

ffind=ui_get_file("get File","") ' lets say selected file = "C:\Users\Ray\Downloads\Alpha_QuickViewSetup.pdf"
fname=strtran(ffind,syspath,"")   '= "Alpha_QuickViewSetup.pdf"
