What is WinForm? How to kill? 20

It is recommended that you use expert software to judge and solve the problem.

Automatic: Super Patrol (version.

Official**) It was once rumored on the Internet that the panda burning incense was made, because the super patrol was the first antivirus software that could completely eliminate the panda burning incense, and everything didn't come out until Li Jun was arrested, but the strength of the super patrol police can be seen from this......

Anti-virus points: 1. To kill the virus in safe mode (safe mode: press F8 to enter when starting, if you can't even enter the safe mode, it is better to reinstall the system, there is basically no hope, of course, you can use the boot disk to enter the safe mode).

2. The management ...... of the startup item

This software can coexist with other antivirus software (you read that right, most antivirus software can coexist with super patrols), and it's very small (4M) and completely free, no nasty serial number, suitable for low configuration or gamers (because it only takes up very small resources, basically does not affect the speed of the computer), super easy to use, the key is that this software integrates the U disk virus immunity program (is immunity), you don't have to worry about it in the future.

Manual: Scan with Super Patrol and other software first, and after the virus is found, it prompts "C: Windows System32 is infected, you do this."

1. Press F8 to enter safe mode, delete (start - search) C: Windows system32, if you can't find it, you need to in the Tools - folder option, display all files, and search once.

2. In F8 security mode, press Start-Run-Enter Regedit, -Find, enter the characters to search, find them to delete, you can use the F3 shortcut key to find the next one.

3. Restart, if you want to confirm, you can use antivirus software to perform a scan.

1. If you're doing a login form, then you should use logic control instead of hiding the form.

2. You can control the logic of the form in it, that is, the form pops up during initialization, and does not enter the main thread at this time, when the state of the first form is closed is the basis for the judgment of the second form, and the main thread is opened, that is, the mainform()).

3. I'll give you a good example......

If you want to open a second interface without letting the user navigate the first screen, then.

form2 form2 = new form2();

That's it.

;;win is an instance of another interface.

;Hide it, don't close it.

Using the hook technique:

dllimport("" , entrypoint = "showcursor" , charset =

public static extern void showcursor(int status);

Call this function where appropriate.

If you put it on the touch screen and don't connect the external mouse, the mouse icon will automatically disappear, and the touch screen clicks on the message is the click message, so it will not come with a mouse icon.

Is your conn not initialized?

For example, sqlconnection connection = new sqlconnection(connectionstring);

There are a few fields in your familyuser table, and whether your connection string is correct.

I haven't run into this problem yet, but if you don't have a primary key, or if there's a null field, or if it's a type conversion error?

You can go to 51aspx and find some source programs developed by Winform.

You submit your resume in this area, and then go to the interview, and if you pass the interview, you should go to the entry level.

This aspect of the work is still good, that is, to be mentally prepared to work overtime.

The database will be added, deleted, modified and checked, and the boss will do whatever he wants, and it will be a bit difficult to say that he has not been contacted!

What does it mean, is it to kill some process, I wrote it before, it's not very difficult, it's a long time ago, I'll find it for you.

Tools - Options - Form Designer - right, one of the properties below the grid size is the appearance mode (mine is the English version of VS2010, the English is layoutmode, the translation may be biased), the default is gridlines, and yours should be changed to snaptogrid. Change it to default, then save, reboot vs should be fine. Please refer to the screenshot for details.

This is a guide for grid alignment provided by the designer during design, which will not be available when it is run. If you don't want to show it, look for it in the toolbar, there should be a button that shows the grid lines. Cancel with a single tap.
