I was using the System.Web.Configuration. WebConfiguration class to open the configuration for the site from one of my logic dll’s and I got the wonderful error An error occurred loading a configuration file: Failed to map the path ‘/’.
I freaked out for a second, until I put more thought into it. This is running fine in production! What is the difference with my machine and the server?
Oh! My Visual Studio is running under UAC with limited privileges since I am in Windows 7. DUH!
So, I restarted Visual Studio 2010 under “Run as Administrator” and problem solved. So if you are on Vista or Windows 7, that’s the issue.
NOTE: If you develop with administrative rights, be careful you don’t make development mistakes that assume everyone will run your program as an admin. i.e. writing to program files directory, root directory, etc.
Happy Coding!

Notebook boot prompt:
ERROR 0210: Stuck Key 24 Press to Setup

, “24” is Stuck, “J”
, find the J Key, cut off the Key cap, clean the base is generally ok. If you’re unlucky, you need to change the keyboard.

Today, I found that the monitoring system kept reporting errors, indicating a Job execution error. Looking at the log, I found that a user who created this Job was deleted (because he left his Job), resulting in a Job error.

When our system user name changes, we will find that the previous good maintenance plan in the original SQL suddenly fails, with the above error message. The solution is to start with SQL security & GT; > Change the original system user name in the login name to the current user name, then delete the existing maintenance plan and rebuild the maintenance plan.

When using VUE Cli3, I encountered the following problems:

error: Parsing error: Unexpected token < at src\views\index.vue:1:1:
> 1 | <template>
    | ^
|   <div class="index">
|     <router-view></router-view>
|     <TabBar :data="tabbarData"></TabBar>

Looking up many websites, can not solve this problem, finally, in
https://stackoverflow.com/questions/53601579/parsing-error-unexpected-token-using-vuecli3-and-airbnb-eslint?r=SearchResults
Find a way
Open your.eslintrc.js file and find the Parser
Here’s my.eslintrc.js

module.exports = {
    rules: {
        'no-console': 'off',
        "parser": "vue-eslint-parser"
    },
}

Note:
This error is reported when I write “import”. In this case, I only need to put the “.eslintrc.js”
“Parser” : comment out “Vue-Eslint-Parser” and restart the project. Then, uncomment it and restart the project again with no error.
Why that should be, I don’t understand. If you have a better solution, please leave me a message, thank you!!
