That link contains the contents in C# language that i already searched for.. Actually i couldn convert that C# code into VB totally.. pls help me in finding vb code.

I dont understand, why are you searching for a readymade code...

All these forums and members here are just to help if you get stuck with something but not to completely do your work...

I dont think its too hard to convert a C# code in to VB.Net Code, if you know the basics and syntax of VB.Net...

Please give a try yourself... That will enhance your ideas and programming skill as well....

My hearty wishes for a successful project....

How to declare/tie a mdigrandchild form to mdiGrandParent form?

How to declare/tie a mdigrandchild form to mdiGrandParent form?
Situ:
I'm writing some code/mdiParent that spawns a child form, child1, that has all the information capturing. Now child1 spawns a child, grandchild. The grandchild is a lean version of child1, readonly type situation. Child1 is not shown, but working. Grandchild is to: Grandchild.show().

Needed:
I need to declare the grandchild to show in the mdiParent. I'm sure it's somthing similar to :

The parent is MainIndiv_Truck_ControlMDI : Form

the child1 is declared in the parent as:

Indiv_Truck_Control TruckForm = new Indiv_Truck_Control();
TruckForm.MdiParent = this.

I know I'm missing something. I can make the grandchildren, but there happening outside the MdiParent. I want them to happen inside MainIndiv_Truck_ControlMDI : Form

Thanks in advance.L.

I am not sure that I totally understand your question, but I think that you want the grandchild form to be bound within the parent form?

If that is so, just set the grandchild forms' mdiparent property to the parent form as well.

I would but what is the method if I can't use:

The parent is MainIndiv_Truck_ControlMDI : Form

the child1 is declared inside the parent as:

child1 = Indiv_Truck_Control TruckForm = new Indiv_Truck_Control();
TruckForm.MdiParent = this;

Then child1 spawns a child of its own, grandchild.

The grandchild has to be inside the MainIndiv_Truck_ControlMDI : Form.
grandchild.Mdiparent = "what"?
I'm not sure how to say the "what"? part.

Thanks

For the grandchild form to be contained inside the grandparent form it must be

grandchild.Mdiparent = MainIndiv_Truck_ControlMDI

otherwise it won't be contained.

You can put a form inside another, but you won't get the benefits of the MDI interface.
Like this:

Form grandchild = new grandchildForm();
grandchild.TopLevel = false;
grandchild.Parent = MainIndiv_Truck_ControlMDI;
grandchild.Visible = true;
grandchild.Location = new Point(10, 10);
grandchild.Size = new Size(100, 150);
grandchild.BackColor = Color.Bisque; // or whatever. this is just to make it stand out
MainIndiv_Truck_ControlMDI.Controls.Add(grandchild);

Ok, I've Googled myself silly. I need to create a List<> instance based on a System.Type instance, the list must not contain a bunch of Type instances like List<system.type> x;</system.type> but more like:

Type objectType = objectInstance.GetType();
List<objectType> objects = new List<objectType>(); //This is where I need to create the list based on the Type
objects.Add(objectInstance);//This shouldn't give an error

The binding of generic parameters occurs at (mostly) compile-time. Unfortunately, what you want can't be done at run-time. The closest you can get is with using Reflection.

Type objectType = objectInstance.GetType();

<span style="color:green">// Create a generic list bound to the Type.</span>
Type unboundListType = <span style="color:blue">typeof</span>(List<> );
Type boundListType = unboundListType.MakeGenericType(<span style="color:blue">new</span> Type[] {objectType});
ConstructorInfo ctor = boundListType.GetConstructor(Type.EmptyTypes);
<span style="color:blue">object</span> genericBoundList = ctor.Invoke(<span style="color:blue">null</span>);

<span style="color:green">// Add a thing to the list.</span>
MethodInfo info = boundListType.GetMethod("Add");
info.Invoke(genericBoundList, <span style="color:blue">new object</span>[] { <span style="color:blue">new</span> Moo() });

Hope that helps.

Thanks for the help, did the trick. Took me a whle to understand what was going on... I'm already using reflection extensively so this fits in to the rest of my design

object constants in c#

How do you use an object to return constants... or to select them...

like:
Whatever.CCN.use.HomePermanent; (when you hit the '.' after 'use' you get other options)

or I would like to set it like this
Whatever.CCN.use = "HP";

So in the 'use' class there would be constants set
HomePermanent = "HP";
HomeVacation = "HV";
WorkPlace = "WP";
Home = "H";

I think an Enum is probably what you're looking for.

Ok I've declared the enum

but now how do I use it in a class struct:

enum nameuse { Legal = "L", Alias = "P", None = "" };

public class theName
{
public string use; // so that this is supposed to only have 3 options
public string prefix;
public string FirstName;
public string Middle;
public string LastName;
public string Suffix;
}

instead of declaring use as a string declare it as nameuse

public nameuse use;
use = nameuse.Legal;

If I'm not mistaken it would be:

public nameuse use;

Then you should get a list when you use InstanceOftheName.use = (List of options)

Also I believe enums have to be a numbered list. Like this:

enum nameuse { None = 0, Legal = 1, Alias = 2 };

If you want something to return a string based on a letter, usually you have to use a function with a switch case statement inside it to return the value you want. That won't give you the nice ordered list in the IDE though.

Of course I've been relegated to the vb6 world of doom for a while now so my thinking could be a bit off on c#.

Yes I just got an error mesg... trying this method on:

Cannot implicitly convert type 'string' to 'int'
public enum nameuse { Legal = "L", Alias = "P", None = "" };

and it points out on each of the stringed items... as if they need to be Integer.

I think I'll go back to Hanlon's method... and attempt that direction.

public static class use
{
  public const string HomePermanent = "HP";
}

This could be used by string myValue = use.HomePermanent; Is this what you're after?

ok I tried your method...

public static class thenameuse {
public const string Legal = "L";
public const string Alias = "P";
public const string None = "";
}

public class theName
{
public thenameuse nameuse;
public string prefix;
public string FirstName;
public string Middle;
public string LastName;
public string Suffix;
}
public theName[] Name;

but from the form class...
cn.Patient.Name[0].nameuse. (I do not get the the const values to populate when hitting the '.') I tried a few things, to no avail. What am I missing?
