How to Insert space before capital letters using Jquery

Assume you have a string "HelloWorld" and you need to show as "Hello World". How you can achieve it using Jquery.

It can be done in a very simpler way as below:

"Your string".replace( /([a-z])([A-Z])/g, "$1 $2")

so here it will be "HelloWorld".replace( /([a-z])([A-Z])/g, "$1 $2") will produce "Hello World"

How to create a File Upload with File Validation in Asp.net MVC / How to Use the @Html.TextBoxFor() for File Upload ?

While Wonder how to validate the Upload control in a easy way, I find this solution as the best to do it, although lot of other ways are found.This is because you need not need to write much more code as a normal razor validation will solve the problem.


My View:


 <div id="dvUpload" class="hide fieldControlContainer">
                <div class="innerDivLeft">
                    <label class="blue">Upload Document:</label>
                </div>
                <div class="innerDivRight">
                      @Html.TextBoxFor(model => model.File, new { @class = "inputTextBox", type="file" })
                      @Html.ValidationMessageFor(model => model.File)
                </div>
 </div>

The magic lies with this line  @Html.TextBoxFor(model => model.File, new { @class = "inputTextBox", type="file" }), here it will be rendered as a file upload control rather than a text because we are over riding the default behavior of input tag rendering by specifying it as type="file".

My Controller:



 public ActionResult Index(HttpPostedFileBase file, MyModel model)
        {
                  //Codes written here.
        }


MyModel:

public class MyModel
{

       [Required(ErrorMessage = "Please select file")]     // this is for model validation
        public HttpPostedFileBase File { get; set; }

}

Now your file upload validation will be checked like any other normal control.

Uploading a file to Server in Asp.net MVC 3 /4.

View page:


@using (Html.BeginForm("Index", "MyController", FormMethod.Post , new { enctype = "multipart/form-data" }))
{
//  Controls for your Model........(see below)

 <div>
                <div class="innerLeftContainer">
                    <label >Full Name:</label>
                </div>
                <div class="innerRightContainer">
                    @Html.TextBoxFor(model => model.FullName, new {@class = "inputTextBox"})
                    @Html.ValidationMessageFor(model=>model.FullName)
                </div>
            </div>


<div id="dvUpload">
                <div class="innerLeftContainer">
                    <label>Upload Document:</label>
                </div>
                    <div class="innerRightContainer">
                        <input type="file" id="DocumentUpload" name="file" />
                    </div>
            </div>


}


Note: The Form Method and the enctype is highly required for uploading your file to the server orthrwise you will always get the HttpPostedFileBase as null.


Action Method: ( in the Controller)
 [HttpPost]
        public ActionResult Index(HttpPostedFileBase file, MyModel model)
        {
            // Verify that the user selected a file
            if (file != null && file.ContentLength > 0)
            {
                // extract only the fielname
                var fileName = Path.GetFileName(file.FileName);
                if (fileName != null)
                {
                    // store the file inside ~/App_Data/uploads folder
                    var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
                    file.SaveAs(path);
                }
            }
            // redirect back to the index action to show the form once again
            return RedirectToAction("Index");
        }

How to lock Your private folder without using any software.

• First select Your folder which you want to lock. Suppose paint is my private folder and it stored into E:\ drive.
• In the same drive ( e.g. E:\) you need to create two bat file. Create a new text file there & Open it in note pad. Type in:
  
  
  Quote:

  ren paint paint.{21EC2020-3AEA-1069-A2DD-08002B30309D}

  Save it in as lock.bat
• Again open another text file and type
  
  Quote:

  ren paint.{21EC2020-3AEA-1069-A2DD-08002B30309D} paint

  Now save this as a unlock.bat .

Now you can see 2 batch files lock and unlock.Double click on Press lock.bat and the folder paint's icon will change to control panel and you cannot view its contents.

Double click on unlock.bat and you will get back your original folder.
