jQuery dialog file upload pop-up in ASP.Net MVC project

Weary of full page refresh form POSTs, Scott cobbled together a jQuery dialog file upload pop-up for an ASP.Net MVC project.



    var j = jQuery.noConflict();
    j('.fileUpload').click(function (e) {
            var page = $(this).attr("href");

                .html('<iframe style="border: 0px; " src="' + page +
                '" width="100%" height="100%"></iframe>')
                    autoOpen: true,
                    modal: true,
                    height: 400,
                    width: 800,
                    title: '',
                    buttons: {
                        "Close": function () {
                    closeText: ''
// -- HTML

<a href="@Url.Action("FileUpload", "CONTROLLER", new { paramOne = item.paramOne, paramTwo = item.paramTwo })" class="fileUpload"><span class="glyphicon glyphicon-paperclip"></span></a>


        public async Task<ActionResult> FileUpload(HttpPostedFileBase files, int paramOne, int paramTwo)
            ViewBag.Message = "There was an error and your upload was not saved. Please contact an administrator";
            var r = SaveFIle(files, paramOne, paramTwo);
                ViewBag.Message = "File Uploaded. Upload another or click Close below";
            ViewBag.paramOne = paramOne;
            ViewBag.paramTwo = paramTwo;
            return PartialView("_Upload");
// PARTIAL VIEW "_Upload.cshtml"


<form method="post" enctype="multipart/form-data" action="/CONTROLLER/FileUpload">
    <input type="hidden" name="paramOne" id="paramOne" value="@ViewBag.paramOne" />
    <input type="hidden" name="paramTwo" id="paramTwo" value="@ViewBag.paramTwo" />
    <div class="form-group">
        <div class="col-md-10">
            <p>Upload one or more files using this form:</p>
            <input type="file" name="files" multiple />
    <div class="form-group">
        <div class="col-md-10">
            <input type="submit" value="Upload" />


(to follow. maybe. and a screen-shot of the clean-ed up version. maybe. and need to break that up into other code blocks. just don’t want to hunt for it later if I re-use it)

C# Random String Generator

Generate a string of random alphanumeric characters in C#. Needed this for naming. NOT FOR USE WITH SECURITY! Need to find the Stack Overflow post this is based on…as usual, it wasn’t the accepted answer, but it was the one I liked that met my needs…

        private string GetRandom(int len)
            var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
            var stringChars = new char[len];
            var random = new Random();

            for (int i = 0; i < stringChars.Length; i++)
                stringChars[i] = chars[random.Next(chars.Length)];

            var finalString = new String(stringChars);
            return finalString;

Especially cool because you can control what characters are used in your random string…

Adding type-ahead to a dynamically generated text box

Needed to add type-ahead to a field on a dynamically created form. Backstory: click the button to add another field group. One of the fields needed to be a type-ahead. So, we have a whole javascript function to add the form:

$('#addit').on('click', function () {
 id = getId(); // an id string based on the current time
 newHtml = updateHtml(id); // the form in on long var
 // console.log(id);

And this is in the $(document).ready() function to handle the type-ahead:

        var autocomp_opt = {
            source: function (request, response) {
                    url: "/Controller/GetTypeAhead",
                    dataType: "json",
                    type: "post",
                    data: {
                        maxRows: 15,
                        term: request.term
                    success: function (data) {
                        response($.map(data, function (item) {
                            return {
                                return item;
                select: function (e, i) {
                minLength: 3,

        $('body').on('focus', '.type', function () {
            $(this).autocomplete(autocomp_opt).on('blur', function () { $(this).autocomplete('destroy') });

Obviously I need a code editor plugin or need to remember the correct way to add code snippets to a post :-/

See http://stackoverflow.com/questions/26498602/enabling-jquery-autocomplete-on-dynamically-created-input-fields . The zero rated answer at the bottom is actually what worked for me.

Here’s a line I forgot about in my controller that I want to remember:

public ActionResult GetTypeAhead(string term, int maxRows)
            var r = new List<SearchTypeAheadEntity>
               new SearchTypeAheadEntity {val="1", label="Text One"},
               new SearchTypeAheadEntity {val="2", label="Second Text"},
               new SearchTypeAheadEntity {val="3", label="Third Value"},
               new SearchTypeAheadEntity {val="4", label="Fourth Code"}
            var val = (from n in r where n.label.ToLower().StartsWith(term.ToLower()) select new { n.label });
            return Json(val, JsonRequestBehavior.AllowGet);

Here’s the updateHtml() function for my own future ref:

function updateHtml(id)
 return '<form id=form' + id + ' method=post action=/mvcController/mvcMethod><input type=text name=name' + id + ' id=name' + id + '><input type=text class=type name=type' + id + ' id=type' + id + '>@Html.AntiForgeryToken()<input type=submit class=skipIt id=submit'+id+'></form>';

Be gentle with the EDMX file…

The worst of my battles with the EDMX file seem to be over. I wish I could remember how I resolved the context name getting lost. If I run into that again, I’ll be sure to post the fix. Here are some other quick notes…

If you update a stored proc, remove it from the following locations, save, and then re-add:

  1. 1st place- Under Complex Types-> as MyStoreProc_result
  2. 2nd Place- Under Function Imports -> as MyStoreProc
  3. 3rd Place – Under Stored Procdures/ Functions -> as MyStoreProc

See http://stackoverflow.com/questions/18038405/stored-procedures-and-updating-edmx

Updating a table or a view just plain doesn’t work. Delete and re-add those, too.

Finding objects on the design surface:

Click an empty spot in the surface and use the dropdown in the properties window to scroll to the object you’re looking for. It will be highlighted on the surface once you select it from the list. It still may not be easy to see, but at least you don’t have to hunt as hard for it.

dBase CYYMMDD integer to usable date

Working on some SQL queries against a database running on an IBM iSeries recently, I had to deal with a numeric date format that (allegedly) makes it easier to compare dates. Right. Right? Here are a couple of select clauses to turn that CYYMMDD integer value into something you can actually use…and read:

-- Convert to YYYY-MM-DD
(INT(MOD(NULLIF(nullif(FIELD_NAME,999999),0),100)))) AS "YYYY-MM-DD DATE"

-- I forget where this one was going...
-- Convert CYYMMDD to YYYY-MM-DD and subtract (current date + 60) from it

Read or write to an XML datasource with C#

Quick post with a code snippet I was looking for to read or write to an XML datasource with C#. YMMV, so be sure to add some error checking 😉

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;
using System.Xml;
namespace XMLConfig
    public class dataAccess
        public static DataSet getData(string fileLocation)
            DataSet ds = new DataSet();
            return ds;
        public static bool setData(DataSet dx, string fileLocation)
            bool status = false;
            return status;
// this is some code to add or edit items in the dataset. These come from a gridview but whatevs
        public void confirmButton_Click(object sender, EventArgs e)
            if (rowNumberField.Value != "new")
                int rowNumber = Convert.ToInt16(rowNumberField.Value);
                GridView1.Rows[rowNumber].Cells[1].Text = editChoice.Text;
                GridView1.Rows[rowNumber].Cells[2].Text = editValue.Text;
                GridView1.Rows[rowNumber].Cells[3].Text = editTemplate.Text;
                GridView1.Rows[rowNumber].Cells[4].Text = selectVisible.SelectedValue;
                int x = 0;
                int y = 1;
                for (x = 0; x < ds.Tables[0].Rows.Count; x++)
                    for (y = 1; y < ds.Tables[0].Columns.Count + 1; y++)
                        ds.Tables[0].Rows[x].SetField<string>(y - 1, GridView1.Rows[x].Cells[y].Text.Trim());
                // DataRow r = new DataRow();
                DataRow r;
                string[] a;
                a = new string[4];
                a[0] = editChoice.Text;
                a[1] = editValue.Text;
                a[2] = editTemplate.Text;
                a[3] = selectVisible.SelectedValue;
                // r.ItemArray = a.ToArray();
                r = ds.Tables[0].NewRow();
                r.ItemArray = a.ToArray();


ClickOnce setup.exe switches

Quick note for a feature I never noticed before on ClickOnce setup.exe switches…they exist!

Use -url to see the URL he executable points to

To change the URL, use -url=newUrlValue

Used this to resolve issues with…other developers building and deploying differently.

WebLogic domain creation is stuck

Quick post for how to resolve an issue when your WebLogic domain creation is stuck at “creating domain security information”

Locate …/wlserver_10.3/common/bin/config.sh and create a backup before editing it

HTTPS website security checkup

Since making changes to this site to force a secure connection, I thought now would be a good time to do a security checkup. I used both the Symantec SSL Toolbx and Qualys SSL Labs site to see how well I did installing my certificate.

HTTPS website security checkup results

Symantec said I was in good shape against the vulnerabilities they check for, but did note that I wasn’t using a Symantec certificate (not made of money, you know)

Symantec says: Ok, but we would like your money

I had run the sslLabs test earlier in the week and had to correct for Poodle by adding the following to /etc/httpd/conf.d/ssl.conf

SSLProtocol All -SSLv2 -SSLv3

I had originally set the value in the virtual host config files, but sslLabs still pegged the grade as a “C”. Making the change in /etc/httpd/conf.d/ssl.conf and refreshing the results brought my grade up to a “B”.

better than a "C", but a "B" leaves room for improvement
Still some work to be done

In the same /etc/httpd/conf.d/ssl.conf file I also updated the ciphers — and learned that you have to add this value to your vhost siteName.conf file also!


and turned off SSL compression for CRIME attack mitigation

SSLCompression off

…and I finally got an A…well, A-

A- after all that work?
At least it’s an A
