I made a login screen with VB Master Advanced

I've done one, it's all registration and login, and querying some related data.

Add an inet1

http: domain name filename.

Detect first if there are no errors in the submitted data.

a = "Domain Name File Name? username=" & a)do while

doevents

loop if a = "The user does not exist" thenmsgbox (a)

else chaxun = a

end if

Log in and change it yourself.

I'm a vb+asp player, which won't work if you're using php.

"http: domain name filename.

Detect first if there are no errors in the submitted data.

a = "Domain Name File Name? username=" & a)do while

doevents

loop if a = "The user does not exist" thenmsgbox (a)

else chaxun = a

end if

Your thinking is not right.,I don't understand a lot of things.,Since you want to remember the password, it must be a commercial network.,But are you obviously a stand-alone system?。

I haven't really done it to open a web page directly from a VB, and I don't think there are many people who can do it.

1. On the desktop, double-click the program with the left mouse button to open the VB programming software, and on the left toolbar, click the [LABEL] button to draw the two labels on the form1 window, which is used to write the description of the text. Write your username and password in this tent.

2, then, according to the size of the window, feel that the text is small, you can modify the font attribute value on the label attribute window, click the chain pants and its selection button to change the font size,.

3. Then, in the pop-up font dialog box, select the size of the four-point font, and click the [OK] button, you can see that the font of the username on the form1 window has become larger. The same is true for the font size of the password.

4. Then, on the left toolbar of the program, click the [TextBox] button to draw two text boxes on the form1 window, and on the textbox property panel, modify the value of text to clear it.

5. Then, on the left toolbar of the program, click the [Commandbutton] button, draw two command buttons on the form1 window in its properties panel, and change the value of the caption to OK. The other was changed to cancel.

6. Finally, on the toolbar on the left side of the program, click the [image] button to draw two picture frames on the form1 window, and modify the two property values, as shown in the figure, after selecting the two icons, re-layout them to look better, click Run, and the login window will appear.

Actually, it's not difficult, I'll tell you about it:

1. Design a registry and a login interface.

2. In the registration interface, the user is required to enter some registration information, with a text box or radio button, you need to save this information to your database for future calls, when the user clicks on registration, judge whether there is a duplicate name or failure, and let the user re-select the user name, if not, the information will be written into the database.

3. In the login interface, there are two text boxes, one is used to let the user enter the user name, and the other allows the user to enter the password, when the user clicks to log in, judge whether the user name and password match, of course, you need to connect to the database, to call up the data from the database and match the information that the user enters the draft in, if the match is successful, then enter the next interface, if it does not match, then return to let the user re-enter the login information, you can also specify the number of errors, super respect over this number of times, Automatically block typing for a minute or more, it's okay, this app is not too difficult, if you need help, you can ask me a question directly, or send me a message.

Hope you succeed!

**It's a bit long, so I won't post it here.

If you want, you can leave your QQ or email address.

Here I will only talk about the ideas: 1When the user presses the login button, look for the username in the text library, if it is not found, the user must be prompted to register, and if it is found, it will be judged whether the password associated with the user and the password entered are correct.

2.When a user registers an account, they must first determine whether there are the same users in the text library, and if there are the same users, then the user cannot be allowed to register, otherwise the text database will be entered.

**Window.

Two methods: 1. Set the login window as the startup object: click menu project - project 1 properties - change the startup object to the login form - OK;

2. Add a module file to the project, and then set the startup object to submain: click menu project - project 1 properties - change the startup object to submain - OK, and then in the module file sub

In the main process, start the login form in modal mode, and then start the main form after the username and password are correct.

It is recommended to use the second method of trouser rounding.

You can select the "VB Application Wizard" when creating a new project, which will guide you step by step to build a complete application framework, including the login form (it is automatically built for you, you don't have to do it yourself), and the startup sequence is also set. If you're a beginner, you'll feel a sense of accomplishment: in a matter of minutes, you can build a fully Windows-compliant API, with standard menus, toolbars, status bars, welcome forms, set up dialog boxes, about dialogs, and even databases, all you have to do is put in your own features.

That's the biggest attraction of VB - it can make a software interface very quickly. Of course, if you don't want to make your own software right away, you can also use this method to study how these standard interfaces are built and what it looks like.
