Is this possible?

[samthemist]

I have a program i made, compiled as an .exe; though each user needs to enter their IP the first time it's opened to have it store their IP.

Then i need it to be possible for them to change it when their IP changes.

How can i do this without changing the code in every project and compiling it separately?

how can you persist such settings?
or, how can you detect when IP changes?

for persistence (storing the value), you can use the registry:

   SaveSetting "myapplicationname", "mysettings", "myip", "127.0.0.1"
   GetSetting "myapplicationname", "mysettings", "myip", ""
 

for checking ip, you'll need something like a winsock control.
make a reference to it in your project (it will be part of components).
then, drop an instance of it on your form.
to get the local ip, simple:

msgbox winsock1.localip

I dont think i understood you quite well, but you have two options, in the code, instead of writing the IP use a String variable, then just put an inputbox where they write their IP each time they start the program. If each user want to save a defoult IP, save it into another archive, the easiest way will be a TXT file.

Something like this will read the file and save its first line into the string called defoultIP or do nothing if the file doesnt exist

Dim defoultIP as string
Dim myIP as string
on error resume next
open "c:\myIPs.txt" for input as #1
input #1, defoultip
close #1

now here we'll ask for an IP adress showing the defoult as the one we've already read. In case we use a different one, it'll be saved as de defoult one.
If there wasnt a defoult one, it'll show the empty string.

myip = inputbox("Please write your IP adress", "IP adress", defoultip)
if myip <> defoultip then
    open "c:\myIPs.txt" for output As #1
    print #1, myip
    close #1
end if

and now you have the ip stored in myIP
