It is possible to open to an application NET (DLL) from a project VB6?
It would interest to send from an application VB a .NET form
Thanks

Thanks, but this was not exactly what I wanted. I have a MdiContainer form in a project VB6 and have an application (form) in NET. What I wanted I was to be able to call to the form of NET from VB6 doing it MDIChildren.
I have been able to call the form NET from VB6, but what with himself he is that habra like a new window and not like a MdiChildren.
Thanks in advance

You didn't post any specifications like this at all, in fact, you didn't post ANY specifications. You got links to documents that generally covered your very general specs.

You have to do the very same thing that's covered in those documents. Your classes, and even a Form is a class, must be exposed to COM so VB6 can use it. Without that, you're sunk.
I've never done it, because I've never had the requirements to do it. In theory, it should work. But I there are potential problems, simply because VB6 and VB.NET manage Forms so differently.

I was able yesterday to do what wanted.
In this page http://www.codecomments.com/archive293-2004-7-228359.html they indicate like opening a form to you within another one, the only thing that I had to replace "hChild" by the "Handle" of the form NET For it I made a method I publish:
Form VB .NET in a project of libreria of classes
Public Function getHandle() As System.IntPtr
getHandle = Me.Handle
End Function
ActiveX Document
'To create the reference to the class .NET
Private Sub initialize()
Dim hChild As Long
Dim hParent As Long
Dim f As New ClassLibrary2.Form1
Dim b As Boolean
hChild = f.getHandle()
hParent = UserDocument.hwnd
b = SetAsParent(hChild, hParent) 'this function is in the Web
f.Show
End Sub
Thanks

can anyone tell me how to parse treeview

That all depends on what you mean by parse?
Parse a string returned by a TreeViewNode? Walk the Tree? What?

i m so sorry that i didnt mention ..
yeah i mean how to Parse a string returned by a TreeViewNode...

Parse the string to what end? are you tying to convert it to a number or what?

I am using visual basic.net only.
I need some help in fractions. How can I use the fractions in system.math to create a fraction program?
I will use two textboxes and a label for the answer within a form
and i will be adding, subtracting, multiplying, and dividing. Can anyone assist with a sample code?

What fractions in System.Math ? VB.NET has numeric types, your core need is Convert.ToDouble(), to convert the text entered into a non-whole number, and ToString, to convert back to a string to put in the label. The rest is trivial.

I appreciate for your time. I am an intermediate programmer, I am not an expert like you. So being trivial I really dont think so in my part. I am trying to learn this solution. I enter a numerator and denominator in the textboxes. There is no text to convert. Trying to figure out how to use the numerator and denominator in a fractional sense in a program. Don't know if i would use the abs or just something else to get the result in the label as a fraction.

There is nothing in the Math namespace to show fractions as fractions. You need to convert to numbers, work out a whole number part, and render it all as text yourself.

I appreciate for your help, but I already know to convert a fraction to a decimal. The code is related only to fraction conversion to decimal.
I would need to know how to render an answer in fraction not decimal.
For instance, 5/8 + 1/8 = 6/8 reduces to 3/4.
So therefore, the textbox1 will be the numerator and textbox2 will be denominator. The third textbox will return the fractional value.
Or textbox3 will be the numerator and textbox4 will be the denominator and this will invoke the answer. I am having the problem of generating a code for the above instance in fractions.

ah, but you never said you wanted to make a formal calculus...
i never searched for that exactly, but looking at some math parsers here on CP should help you to achieve your goal.
moreover, don't 5/8 + 1/8 make 6/8 ??? 
anyway, nevermind, i won't repeat it

It's only an example.
In a tape measure would be 3/4 of an inch.
And Yes, it would also be 6/8 but reduce it to the LCD would be 3/4.
That's the only problem that I am having, using the fractional portion to render an answer in fractions. There is a site called Break Tru, and they are selling a fraction and decimal program, but can't get the code for that program. For what I want it for is for several fraction programs.
Does your home have heat oil. Then you would know that the tank only reads in fractions. I created a program that will give you how much oil you have in your tank and the amount you need to refill it, and how much it will cost you, and the amount of tax and a grand total. I also added on the form a fraction to decimal converter, which is the only i can offer under that program because I don't know how to render the fraction resulting in fractions. If you know of anything or a book that I can purchase in algorithm please let me know. I am up to programing almost in calculus. LOL
Thanks Bro for your help.

If you go to Jesse Liberty's site
http://www.libertyassociates.com/pages/book_edit.htm[^]
and download the source code for Programming C# 3rd edition then you'll find a (simplified) Fraction class that you could perhaps adapt for your purposes. It's in the Ch 6 folder.

Re: Jesse Liberty - Programming C# - he has a VB .NET version of the same book with source code so you could download the source for that one instead.

I appreciate for your info. I'll try Jesse's book.

This sounds more like an issue with Math than it is VB .NET 
It's just a matter of making the right calculations to display the appropriate whole number.

Oh no, i know how to calculate fractions without a problem, is that how do you use the textboxes to display fractions. That's the problem.
I've seen it done through C#, but I tried to use it in VB.Net, and it doesn't work. So the solution is in progrmming in VB.Net. That's all.
I appreciate for your feedback.
