A generic error occurred in GDI+ while creating image from Base64 string

In a web service, while converting a Base64 string to file, it is sometimes giving error  - "A generic error occurred in GDI+ while creating image from Base64 string".

Solution:

I have used the below code and problem resolved.

[HttpPost]
public ActionResult UploadSignatureTwo(String imageString){     
    var bytes = Convert.FromBase64String(imageString);
    using (var imageFile = new FileStream(Path.Combine(path,"test.jpeg"), FileMode.Create))
    {
        imageFile.Write(bytes, 0, bytes.Length);
        imageFile.Flush();
    }
}

svg file not upload in wordpress

Cannot upload SVG files in WordPress

When we upload the SVG file, we recieve the notification “Sorry, this file type is not permitted for security reasons.”

To Resolve this issue, we need to add the below function in the functions.php files

function cc_mime_types($mimes) {
 $mimes['svg'] = 'image/svg+xml';
 return $mimes;
}
add_filter('upload_mimes', 'cc_mime_types');

This will resolve the issue.

Datatable.net - Get Reordering of the columns & Get Column visible

Datatable.net - Get Reordering of the columns & Get Column visible

Please add a button on the form like below

<a class="btn btn-success visiblecheck" href="javascript:void(0);" id="visiblecheck" value="test">visiblecheck</a>

Here is 'table' is variable of Datatable.net like

var table = $('#example').dataTable();

$('.visiblecheck').click(function () {
        alert(table.colReorder.order());
        var columnvisible = '';

        for (i = 0; i < table.columns().count(); i++) {
            if (columnvisible != '') {
                columnvisible += ',';
            }
            if (table.column(i).visible() === true) {
                columnvisible += '1';
            }
            else {
                columnvisible += '0';
            }
        }
        alert(columnvisible);
    });

table.colReorder.order() -  this will return the ordering of columns

whats the difference between == and === ?

The difference between == and === is that:

1. == converts the variable values to the same type before performing comparison. This is called type coercion.
2. === does not do any type conversion (coercion) and returns true only if both values and types are identical for the two variables being compared.

Example:

1. var one = 1;
2. var one_again = 1;
3. var one_string = "1"; // note: this is string
4. console.log(one == one_again); // true
5. console.log(one === one_again); // true
6. console.log(one == one_string); // true. See below for explanation.
7. console.log(one === one_string); // false. See below for explanation
