This article from the csdn blog, reproduced please indicate the source: http://blog.csdn.net/jinghaianlange/archive/2007/07/16/1693676.aspx There are many causes of errors. For example, if you enter a value of the error type, or the script cannot find the required file, directory, or drive, we can use Loop Technology to handle errors, however, vbs also provides some basic technologies for error detection

I learned the Exception Handling Mechanism of C # today. I will summarize it as follows: I. keywords used for exception handling in C # Try is used to check for exceptions and help send any possible exceptions.

One: Error, Debug and test1 errors in the program run:A problem with programming a program, which we often call bug,bug, must be fixed.b user input can be caused by checking user input to do the corresponding processing.c there is a class of error is completely unable to predict during the program running, such as when writing to the file, the disk is full, write not in, or fetch data from the network, the

Although it is called an error, it is one thing to do with exceptions in C #. It's just that Python is called a mistake (error) and C # is called an exception (Exception).Create an exception manually first:1 file = open ("','r')The above sentence because the path is an empty path, so the file certainly does not exist,

If the error shows up, it's easy to expose1. server file path and file storage specification2. Some people like to be named after a personal name, through social engineering can reverse the reasoning of the password3

1. Use window. onerror to specify the error handling function. When an error occurs, onerror is called back. When multiple script errors exist in a javascript block, the script after the first error is triggered (callback) is automatically dropped and not executed. For example: CopyCode The Code is as follows: In

error is relatively rare (try new one with a length of 100 million), also due to insufficient heap space. If a new array of this size is needed, the logic of the program is mostly unreasonable.FIX: Modify the program logic. Or, you can increase heap memory by-XMX.when the GC spends a lot of time, but only a small amount of memory is recycled, OutOfMemoryError is also reported, and I've only met one or two times. When using the-XX:+USEPARALLELGC or-XX

A preface: Exception handling is more familiar to developers who do object-oriented development, for example, in C # Try { ... } catch (Exception e) {...} finally{ ..... } In C + +, we often use the try{} ... catch () {} Block for exception handling.
