VFP how to get the login box, the code about the VFP page box

Create a form, then add two text boxes text1 and text2 to the form to enter the user and password, respectively. Then add two buttons, called OK and Exit.

Let's say your username is called "user" and your password is "123".

Add the following to the click event of the OK button.

if <>"user" or <>"123"

messagebox("Wrong username and password! Please re-enter")

elsedo form main&&&This is the form that you run after you have successfully passed the verification.

endifps: If you want to enter a password that no one can see, for example, if you enter a character and it will show "*".

You can change none to * in the passwordchar attribute of text2 in the text box where you enter the password

This is the easiest way to authenticate, and if you want to have multiple users, the last thing is to create a table with the user's name and password.

Then verify that the user and password are in this table when logging in, and if so, and the password is correct!

It is to use a form, two text boxes, one to enter a name, one to enter a password, two buttons, one to confirm, and one to cancel. Confirm the click** to verify the password, turn to the specified position after passing, otherwise an error will be prompted, and the cancel button will exit the program.

Write ** in the activate event in page2.

Right-click on the page box, select ", and a blue line will appear on the edge of the page frame, and then add a control to each page.

Instead of adding the control to the first page, you add the control to the entire page frame......

Note that you must select page1 and then put the button, not pageframe1.

Right-click the page frame, select, and then click the second page tab.

Try: use login form.

if empty(

messagebox("The username or password cannot be empty, please re-enter it",48,"System prompts")

elselocate for alltrim (login table. username)==alltrim(;

and alltrim (login form. password) ==alltrim(if found()

messagebox("Success")

elsemessagebox("The user or password does not exist",46,"System prompts")""

endifendif

In the top position of the page box, that is, all the data, select page2, and then the slag clear god page frame becomes a light blue frame line, and you can add the second table to page2

You obviously didn't select the page box first and added** (it should be**control, ha, I guess you wrote it wrong).

Open the form, click on the property window, there is a drop-down option box on it, use that to select your first page box, and then add**, the same selection of the second page frame is adding**, so that the key grid belongs to the page frame control.

You take a look in the properties window, you can select the control at the top, you can select a page in the page box to do the dragging.

No, the top of the properties window will show the name of the control you are operating, and there is a small button on the side, which is a drop-down button, click on it and select page1

Right-click on the page box——— select page 1, and drag the table up.
