Datagridview is not populating when submitting from winform search button

I currently have a C# winform that is compiling with zero errors and zero warnings:
This is my first go at a winform project:
Note: I have a similar project in ASPX that is working as expected
However this one needs to be in a winform.
I also need to start off with an empty datagrid because in the production environment the table we will be calling holds millions of rows.
(this cannot be a filter the datagrid type solution it would kill the server in production.)
the winform is super simple consisting of:
a form: GetParentID
a Text box: textBoxValueToSearch
a button: BTN_SEARCH
a data grid view: ParentIDOutput
a connection string in app.config : RCPDEV (tested and working)
Problem: when I enter a value in the text box and click on the search button I'm expecting a single Parent_Container_Id to be returned in the data grid view. However clicking on the button does nothing.
I have tested the stored procedure code and this is working properly:

Any ideas on what the heck I am doing wrong here
/ i have been pulling my hair out for the last 16 hours or so trying many different things and reading whole lot of articles/tutorials/and help tickets to no avail.
I am at your mercy a to being able to fix this.

You should subscribe event like Control.Click to response any action by user on winform control.
// BTN_SEARCH
//
this.BTN_SEARCH.Click += BTN_SEARCH_Click;
Or you can subscribe MouseClick.
You should look into Control.Event list to find out what event fit into your situation.
You can subscribe event on Properties Window instead write code.

Why has my code become recursive within form1?

I've been working on a bit of software in c# and it was going nicely but as of yesterday evening I noticed that it was throwing a memory exception error at the point when it loads an image.
I tried to decrease the image size but then realised that 'declaring rats' was being printed repeatedly to the console, where it should only occur once.
Digging a little deeper with some break points I found that it enters the drawing constructor at allRats = new Drawing(HousePicBox, DekuPicBox, BakuPicBox); //THIS HAS BECOME RECURSIVE, WTF
yet it doesn't seem to run the code within the constructor, but jumps back to the start of form1().
I have included all of the code within the files which the Program Counter touches.

Honestly I'm baffled as to why it keeps jumping back to the start of form1.
What have I broken?

As Drawing is derived from Form1 & you create an instance of Drawing in the Form1 constructor - this is going to cause the Form1 constructor to be invoked again which causes the creation of another instance of Drawing which causes ........... -
Note the base class constructor is called before the code in the derived class constructor - which is why you don't get to the code in the Drawing constructor.

How to use custom class with dynamic compilation

I have a form that i dynamicly compiled and i have a style class. When i copy this style class to my form source and compile it all works fine. But how can i use this style class without copy it to my form source. My main program that compile this form has this class, how can i use it? Maybe i can pass style class to this for with i compile it, like a var?

Style source:
http://pastebin.com/CjmQQ9ND
Project source - https://yadi.sk/d/ChtMacrsraD4g
If you compile this source, all will work fine. That because i use style at form.txt file. I separated form from style at form.txt file. I have this style at my main program (you can see that at screenshot). How can i send this style class to my dynamicly compiled form, so form can use it.

You should be able to simply append the style to the source like so:
var source = File.ReadAllText("form.txt");
source += Environment.NewLine;
source += File.ReadAllText("style.txt");

Inside Form.txt file instead of the classes in order prescribes the macro:
namespace myForm
{
<%THEME%>
}
namespace myForm
{
<%THEMEBASE%>
}
Before compile, load style files and replace them in the code form:
//Load style files
var NSThemeSource = File.ReadAllText(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, #"..\..\Class\Style\NSTheme.cs"));
var themeBaseSource = File.ReadAllText(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, #"..\..\Class\Style\ThemeBase154.cs"));
var source = File.ReadAllText(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Form.txt"));
//Substitute in the form styles
source = source.Replace("<%THEME%>", NSThemeSource);
source = source.Replace("<%THEMEBASE%>", themeBaseSource);
P.S.
You can switch build action for style files at Embedded Resource so you can get style class from exe.
And use this helper - http://www.vcskicks.com/embedded-resource.php
Than you need to change code to:
var NSThemeSource = ResourceHelper.GetEmbeddedResource("Class/Style/NSTheme.cs");
var themeBaseSource = ResourceHelper.GetEmbeddedResource("Class/Style/ThemeBase154.cs");

First, you need to make classes, enums, and etc. public in NSTheme.cs and ThemeBase154.cs.
(it is better to put into some namespace, rather than having them in the global (dynamic) namespace).
Then, add parameters.ReferencedAssemblies.Add("dynamic.exe"); to you exe file (you might want to put your styles in a separate dll).
After it, in your form.txt add using dynamic; and remove qualifiers from new myForm.NSTheme() (so, it becomes new NSTheme()).
Now you can use your styles without coping them to your form class.
In case you miss something, check the CompilerResults results errors for particular problems.

Ways of displaying exe icons in a ListView

Using a ListView, I need to display (large) icons for an array of executables.
Is there a standard way of doing this / a "Pattern" (whether Design or otherwise)?
A wrinkle: these .exes should be runnable from this ListView ONLY. If a person were to navigate to the .exe via Explorer, they should not be able to run them from there. IOW, the user must log in to the system before seeing the array of program icons (and what they see will depend on their role)*, and that is the ONLY gateway to run those apps.
So, these app icons must be added programmatically.
Ideas?
Update:
Trying to use the code below to create a "Quick and Dirty" app.
Here's my code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
namespace ListViewWithAppIcons {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
DirectoryInfo dir = new DirectoryInfo(#"C:\SpotRun");
foreach (FileInfo file in dir.GetFiles()) {
try {
this.imageList1.Images.Add(Image.FromFile(file.FullName));
} catch {
Console.WriteLine("This is not a Duck-billed Platypus");
}
}
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(32, 32);
this.listView1.LargeImageList = this.imageList1;
//or
//this.listView1.View = View.SmallIcon;
//this.listView1.SmallImageList = this.imageList1;
for (int j = 0; j < this.imageList1.Images.Count; j++) {
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
}
}
}
}
..and here's the "code generated by a tool" (not me, the other tool):

partial class Form1 {
/// <summary>

Hi Clay, I need to reference a superfluous Princess Bride!
An example off MSDN so you know your coding it up sweet:
private void Form_Load(object sender, EventArgs e)
{
DirectoryInfo dir = new DirectoryInfo(#"c:\pic");
foreach (FileInfo file in dir.GetFiles())
{
try
{
this.imageList1.Images.Add(Image.FromFile(file.FullName));
}
catch
{
Console.WriteLine("This is not an image file");
}
}
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(32, 32);
this.listView1.LargeImageList = this.imageList1;
//or
//this.listView1.View = View.SmallIcon;
//this.listView1.SmallImageList = this.imageList1;
for (int j = 0; j < this.imageList1.Images.Count; j++)
{
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
}
}
To prevent people from opening the exe's (except from your program) is pretty hard, it would be easy if you wrote all those applications and could require a secret argument (as in like a command line arg) be passed in to start the other applications. But using Process Monitor/Explorer users could find out the secret key.
Alternatively you could hide the exe's in some folder but the trick here is that the name of the exe will be shown in Task Manager and once users see this they could search for the exe. I mean you could get around this using my technique here, but how deep is the rabits hole: How to hide C# application from taskmanager processtab? - see my answer, its got the most votes.
Maybe a better solution than all this mucking around hiding stuf from users would be - Kiosk mode: http://support.microsoft.com/kb/555463
