Solution: Press F1 to enter Bois, then press F9 to load the default value, press F10 to save and exit, and the system will restart normally.
Note: please check the corresponding commands of the corresponding model for specific access to BIOS.
This is because Microsoft considers the strcpy() function unsafe.
Solution: add at the beginning of the code
#define _CRT_SECURE_NO_WARNINGS You can use it.
ads sometimes cracked incomplete, designguide can not be used
Possible reasons:The installation location is in the c drive, you need administrator privileges to unzip the files, and designguide’s zip package has problems when cracking and unzipping.
Solution:Manually decompress the files to other folders, then copy them over, and delete the original zip package.

Solution:
This problem is only applicable to windows, if it is linux or mac, please follow the relevant instructions to use the shell statement to configure in the termination.
If the sdk is installed on Windows, enter cmd in the run, call up the windows command line, enter adb, and the system feedback says that it is not a system command. . . . .
The solution is simple:
Go to the tools directory under the Android sdk directory, find two files, adb.exe and AdbWinApi.dll, select them, copy them, and paste them in the system directory /windows/system32/.
Then enter adb in the command line, the problem is solved!
Background: when compiling UE4 C + + project, there are unknown structure and other errors;
After the query, it is found that after the structure defined in C + + is exposed to the blueprint, a new container is re created, including many structures. The data type of this container is defined as: allzmqdatapool
Define a new variable in gameinstance. The variable type is allzmqdatapool; Create a method to quickly get variables in common func.
The above problem occurs when packaging after compilation.
Less nonsense, the solution is as follows:
1. Directly modify the name of the structure container; After modifying the name, recompile from the C + + project, then reopen the project, package and solve it;
2. If there are only a few sporadic errors and you don’t want to change your name, you can select refresh all nodes in the blueprint of the error report through the “file” option, and then compile again, repackage and solve it;
Basically, the above two methods are easy to use.
