FileList is a command-line utility that generates a CSV file listing the contents of a given directory. By default, the list includes the file name, size, and path, as well as the last-access, last-modified, and creation dates, etc. You can easily import all results to a spreadsheet or database.

This utility supports additional arguments to control what information you need.

.\FileList.exe /A * /NOTITLE /ADDITIONALCOLUMNS FILES,ATTRIBUTES "\\Server\Documents" > ListOfFiles.csv

In this, you won't have title info, and you will also get the number of files in a folder and their attributes.

If you want to send the output of this utility to both the console and a file, use the Tee-Object in PowerShell.

.\FileList.exe /A * /NOTITLE /ADDITIONALCOLUMNS FILES,ATTRIBUTES "\\Server\Documents" | Tee-Object -FilePath "ListOfFiles.csv"

As a fallback what we can do is, pass a know default value to the flow and in flow check for the known default value and convert it to null in the Execute sp action.

if(lessOrEquals(triggerBody()['Executestoredprocedure(V2)_FieldData'],0),null,triggerBody()['Executestoredprocedure(V2)_FieldData'])

If the current value in the passed value is 0 or less, null will be passed to the db else the original value.

From power app , you can initiate a flow call by the below code

SampleFlow.Run(If(IsBlankOrError(cmbUser.Selected.ID),-1,cmbUser.Selected.ID),...)

If the value of cmbUser is null or invalid, -1 will be used when calling the flow. (known default value)

TL;DR - Remove existing node installations, install nvm, install node versions under nvm nvm install <version>, use the version nvm use <version>

If you have already installed nodejs, lets start by removing it first

1. Make a note of the existing version of node and npm

   1.  node --version
       npm --version
      

2. Clear cache

   1.  npm cache clean --force
      

3. Uninstall nodejs from you machine

4. Delete all files from the below folders

   • C:\Program Files (x86)\Nodejs

   • C:\Program Files\Nodejs

   • C:\Users\{User}\AppData\Roaming\npm (or %appdata%\npm)

   • C:\Users\{User}\AppData\Roaming\npm-cache (or %appdata%\npm-cache)

   • C:\Users\{User}\.npmrc (and possibly check for that without the . prefix too)

   • C:\Users\{User}\AppData\Local\Temp\npm-*

5. Download and install the nvm-setup file for the most recent release

6. After install take a new terminal and check for the installation using the command where nvm

7. To list the installed node versions nvm ls

8. To list the available node versions to install nvm list available

9. To install required versions, use nvm install <version>

All set!, now to use a specific version of node, use the command nvm use <version>

SSL certificate problem: unable to get local issuer certificate

This issue can be frustrating, but fear not – there's a simple solution to it. In this blog post, we'll explore the reason behind this problem and the steps to resolve it.

Understanding the Issue

The "SSL certificate problem: unable to get local issuer certificate" error occurs when Git, the version control system that underpins GitHub, can't verify the authenticity of the SSL certificate presented by the server. This is a security measure to ensure that you're connecting to the right server and not being intercepted by malicious actors.

The Reason

One common reason behind this error is that Git is configured to use the OpenSSL SSL backend instead of the Windows certificate store. This means that Git is not utilizing the certificate store that Windows uses to manage SSL certificates.

You can verify your current SSL backend configuration by running the following command:

git config -l --show-origin

If you see http.sslBackend set to "openssl", it indicates that Git isn't using the Windows certificate store.

The Solution

To resolve this SSL certificate problem, you need to switch Git to use the "schannel" SSL backend, which will make it utilize the Windows certificate store. Here's how you can do it:

1. Open a terminal or command prompt: You can use the terminal or command prompt you use for Git commands.

2. Run the following command:

git config --global http.sslBackend schannel

This command sets the global Git configuration to use the "schannel" SSL backend.

1. Try cloning the repository again: After setting the SSL backend to "schannel" attempt to clone the repository that was giving you the SSL certificate error. It should work without any issues now.

Conclusion

Encountering SSL certificate problems when trying to clone a GitHub repository can be frustrating, but understanding the reason behind the issue and knowing how to resolve it can save you time and headaches. By switching Git to use the "schannel" SSL backend, you ensure that it utilizes the Windows certificate store, allowing your stored certificates to be picked up correctly.

Next time you encounter this SSL certificate problem, remember the simple solution: run git config --global http.sslBackend schannel, and you'll be back to cloning repositories without a hitch.

MySQL - Visual Studio Marketplace

Download and run a MySQL Server Docker Image

docker pull mysql/mysql-server
docker run --name=mysql1 -p 3306:3306 -d mysql/mysql-server

Check logs to see the generated root password (look for GENERATED ROOT PASSWORD)

docker logs mysql1

Connect to the running server as root user and then create a new user for localhost

mysql -u root -p

CREATE USER 'sqluser'@'%' IDENTIFIED 
WITH mysql_native_password BY 'password' ; 

GRANT ALL PRIVILEGES ON *.* TO 'sqluser'@'%' ;

FLUSH PRIVILEGES;

Now mysql server is ready to be connected from host machine. I used an extension called 'MySQL by Jun Han' in vscode

• To add MySQL connection: in Explorer of VS Code, click "MYSQL" in the bottom left corner, then click the + button, then type host, user, password, port and certificate file path (optional) in the input box.

• To run MySQL query, open a SQL file first then:

  • right click on the SQL file, then click Run MySQL Query in editor context menu (Note: you could also run the selected SQL query)

  • or use shortcut Ctrl+Alt+E

  • or press F1 and then select/type Run MySQL Query

    SELECT *
    FROM Sales.SalesOrderHeader
    WHERE OrderDate BETWEEN @StartDate AND @EndDate
END

× Migration failed: Incompatible peer dependencies found. Peer dependency warnings when installing dependencies means that those dependencies might not work correctly together. You can use the '--force' option to ignore incompatible peer dependencies and instead address these warnings later. See "C:\Users...\angular-errors.log" for further details.

Below are the steps that I follow which works. For this example I am mentioning the steps for updating from v12 to v14

npm update

npx @angular/cli@13 update @angular/core@13 @angular/cli@13 --force

commit your changes! else on the next update you will get an error

Error: Repository is not clean. Please commit or stash any changes before updating.

npx @angular/cli@14 update @angular/core@14 @angular/cli@14 --force

commit again

Now we use npm-check-updates or npm itself to update all the depend packages which needs to be updated

npx npm-check-updates -i or npm install {package-name}@* {save flags?}

then

npm audit fix

Now try running your application. npm start

Happy Coding!

jSignature is a JavaScript widget (a jQuery plugin) that simplifies creation of a signature capture field in a browser window, allowing a user to draw a signature using mouse, pen, or finger. By default it supports data-url-formatted, base64 encoded (likely PNG) bitmap data. Due to this functionality we will need to enable data: for img-src in applications csp setting, which is not a great thing. In this post we will see how to develop an import plugin for jSignature which can support signature data as urls and in turn make csp scrict (img-src 'self';). This post will also help you to extent the inbuilt functionality of jSignature.

$(function () {
    var mothership = $.fn['jSignature']
    mothership(
        'addPlugin'
        , 'import'
        , 'image-url' // alias
        , function (imgUrl, formattype, rerendercallable) {
            var img = new Image()
                // this = Canvas DOM elem. Not jQuery object. Not Canvas's parent div.
                , c = this

            img.onload = function () {
                var ctx = c.getContext("2d").drawImage(
                    img, 0, 0
                    , (img.width < c.width) ? img.width : c.width
                    , (img.height < c.height) ? img.height : c.height
                )
            }
            img.src = imgUrl
        }
    )
});

And now we can use the plugins functionality by specifying the alias on importData

let signData = 'https://example.com/getsignature?id=1'
$('#signatureElementId').jSignature('importData', signData, 'image-url')
