You have to set id and password in code using if loop and you cant change it. If you want to change id password then you have make changes in code.

may be it is possible, but sorry i don't know how to make changes in code from runtime.


If you dont want to use database to store the login and password detail then you have a choice to store the data in file or use XML to store the login data.

Hope this will help you.

Please refer the below links to work with XML.[^][^]

If i want store in file
can give some example??
can save as .dat file??

the best way is to store into XML. Because reading and storing data into XML is easy and efficient. I have update some link to work with XML.
Since you are creating a desktop application storing the userID and password would depend on the number of users. If there will be only one user then I suggest keep the userID and password in registry. If there could be multiple users then keep them in an XML file in some isolated storage.

Note: In both the cases do not store it in plain text. store it in encrypted format.

let say this application only one user, as you mention i keep in registry.
is it possible if user want to change password or username??

yes you can. you just need to write a class to read and write the registry.
