What is the error cos the above code is ok

if enters Admin sets the editbox to readonly
if enters 1234 shows form2

if neither above are true then shows 'Incorrect username and password'

I've figured it out now.
Thank you for ur help.

Just a quick question, How would I encrypted the username and password?

how did you do it in your login screen?? that's also one of my problem.. I'm doing a system that has a login screen and if the privilege is student then it will open immediately the student forms which can only view the information. Thus, if the privilege is physician then it can add, edit and view the information. But, still, I don't know how to do it..

I'm guessing you were getting an access violation error, which usually means you are trying to access properties of an object that has not yet been created. Has form2 been created already but has been hidden or visible:=false?

For encryptions, depends on how secure you need it to be. Some easy things you can do is:

1. Add an offset to each character, like "M" is an ASCII 77, so replace it with ASCII 127, for example. Similarly, you could do all sort of character-by-character operations, like vary the offset according to the position in the string, or make other bit-level changes.

2. Jumble the letters

3. Mix the string in with another long and randomly generated string.

4. Use a public-key type routine. The math is easy, but to be effective you have to use some big numbers.
