How to make the dialog box not close, the dialog box on the computer can t be closed

You can close the window to close the book, but you can't make it "invalid", if you open multiple windows, you can press the alt+tab key, it will show all the open windows, and then hold down the alt key, each time you press the tab key, it will automatically turn back a window, select the window you want to close, and then alt+f4 on it!

If you make a button "invalid", it may involve changes to the registry, even if you change it this time, if you want to use it in the future, you will have to change the registry, which is very troublesome.

Overload cwnd::windowproc

virtual lresult windowproc( uint message, wparam wparam, lparam lparam );

In this way, the program will not receive any messages, and of course it will not be closed.

You can also just block the closing message here.

In the message response function, intercept alt+f4 and return 0 directly.

Determine the reason for closing in the closing event, and cancel the closing message if it is not the system's reason!

Summary. Hello.

Can you specifically describe the dialog box, no, or take a screenshot of the picture, I see, there is generally a dialog box that can't be closed, which may be caused by a virus.

The dialog box on your computer won't close.

Hello, can you specifically describe the dialog box, no, or take a screenshot of the picture for me to see, generally there is a dialog box that can't be closed, it may be caused by a virus.

This one can't be turned off.

No. This is not the X point on it, and there is no response.

Open Task Manager.

Just click to end the program.

Still can't be closed.

Just turn off the computer.

Rebooting is normal when trying to turn it on.

Sometimes it's a problem with a program, uninstall and reinstall. If it is a computer card, you need to find out the reason, and the network will be slow too, the original card, crash or slow response? What did you do before crashing or slowing down?

1. The antivirus software is installed more, and all the monitoring is turned on, less monitoring is turned on or not monitored, and the virus is often checked and killed.

2. The software or driver is not compatible with the system, and the driver should be reinstalled or upgraded.

4. Memory, graphics card, and voltage instability can also cause crashes (if the memory is too small, upgrade the memory).

5. The temperature of common hardware such as CPU or graphics card is too high, which is most likely to cause card and crash.

6. If the hard disk has bad sectors, use software to repair the bad sectors of the hard disk, format the hard disk, repartition and reinstall the hard disk, and replace the hard disk.

7. Upgrading the hardware causes an incompatible crash.

8. Too many junk files, too many disk fragments, etc.

9. If it always doesn't work, it is recommended to overhaul it.

Use the system restore method from the spring zone:

The system comes with System Restore: "Start" "Programs" "Attachments" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see the date page has a dark date, that is the restore point, after you select, click Next to restore (win7 restore the system, in the control panel then the device and security sub-option and then the backup and restore sub-option).

Caton, it should be the reason for the CPU.

If this is what happens when you boot up, because the program is loading in the background when you boot up, it will work later.

This is caused by the card, or it may be that you have multiple programs open, or play games, use the computer for a long time, etc., and restart the computer. If it is caused by the above problems, try to open the program as little as possible, or don't let your computer be too stuck, the computer is stuck, you are refreshing or right-clicking on something else, so it is normal, you say so, right? If it is a system problem, check and kill the Trojan, restore the system, or reinstall it.

Hardware-wise, test if your CPU is too hot? Is there a problem with the hard drive and other hardware? If the memory is not large, it is recommended to add a memory module to have obvious results, and the monitoring of antivirus software should be turned on as little as possible (sometimes the graphics card is not suitable or there is a problem, sometimes it is impossible to remove the program itself, if it is, change to a similar program).

Restart your PC for a temporary fix or see below.

Open Task Manager to end the process "explorer", and the desktop icon and taskbar are gone. Open the task manager (press "Ctrl+Alt+Del" to open it), click "File" "New Task", enter "explorer" in the "Create New Task" dialog box that opens, click the "OK" button, wait a while and you will see the desktop icon, you are looking at it.

Steps to resolve application errors:1First of all, rule out the cause of the virus, use antivirus software, such as the latest version of 360 Antivirus Quick Kill 3 5 minutes, according to the inspection results, click to deal with it immediately.

2.If the application error prompts that a file is missing, it may be that the file is corrupted, according to this component to query which system component is damaged, reinstall the relevant component, restore the program file, and generally solve the problem.

3.If the components of the software itself are missing, you only need to reinstall the software. For example, when running Thunderbolt, it prompts that a certain file is missing, you can try to reinstall Thunderbolt.

4.If the above method does not work, it may be a conflict between the software. The workaround is to try closing a couple of unrelated running applications and see if the error will reproduce.

If it has been resolved, you will know which two software conflicts are and can be resolved by not running both software at the same time. Or feedback the fault to the manufacturer and urge the manufacturer to upgrade and solve it. If you don't know which software conflicts, the feasible solution is to use 360 Security Guard's system optimization, and in one-click optimization, turn off some infrequently used software startups.

In this way, there are fewer programs running after booting, and the probability of collisions will decrease.

5.For another application error, the screenshot shows "the application is faulty, the **memory address cannot be read or written", this situation is the most complicated, if the above methods can not be solved, it is likely to be a hardware (mainly memory) failure, may be poor compatibility, can only contact the hardware ** vendor for repair. Or reinstall the system, which may be effective for a short time after reinstallation.

Summary. Explorer is just an explorer, closing it will not cause any harm to the system, running the game does not rely on explorer, so closing it while playing will not affect the game. There is no big impact on other aspects either.

The dialog box on your computer won't close.

Turn off from the Program Manager.

How to do it. Keep your computer on your desktop and press Ctrl+Shift+Esc2 to open Task Manager.

I see, but what effect does turning off this explorer have on the computer?

Screenshot to me. Explorer is just an explorer, closing it will not cause any harm to the system, running the game does not rely on explorer, so closing it while playing will not affect the game. There is no big impact on other aspects either.

What the hell is a black screen.

Click Run New Task on the drop-down menu.

Enter and click OK.

Once it's running, the desktop will come out.

Where is the click drop-down menu.
