answer to 1 and 2 is no. C+ simply has too rich a library to convert to simpler langauges like VB.NET, or even C#.
The answer at the end is yes. VB has always stood on the shoulders of C++. You can call any C# dll from VB.NET, and any C++ COM dll from C# and VB.NET. You can also compiled managed C++ ( pretend C++ ), which you can call directly.

ah... ok.. thanks.. but will it run just the same as just it was in visual c++ when it is already in a vb.net environment?

Of course. Why would where it was called from change the code ?

How to delete or Remove Item with image from ListView in C#?
I am creating a ListView and setting a LargeImageItem. I am adding each item of string and index of the image. I also adding image to LargeImageList. Here is the code snippet in C#.NET
ListView lstView = null;
String fileName;
int index = 0;
private void addImage(filename, index){
lstView.Items.Add(fileName, index);
lstView.LargeImageList.Images.Add(Image.FromFile(fileName));
...
}
Now I want to remove item from the ListView. Here is sample code.
private void removeImage(index){
lstView.LargeImageList.Images[index].Dispose(); -----line 1
lstView.LargeImageList.Images.RemoveAt(index); -----line 2
lstView.Items[index].Remove(); --line 3
//lstView.Items.RemoveAt(index); --line 4
lstView.Invalidate();
...
}
If I use line 1,2,3 then if I try to delete 3rd image out of 5 image item in the list then it deletes 3rd image also deletes last image. If I use only line 3 or 4 then while deleting it works fine but if I add another image then it keeps the old image list pattern no matter which image I add.
Does anyone come across this problem? If anyone knows better idea, How to delete ListView item with image associated? And also able to add item after wards.
Hope it is interesting problem.
Thanks in advance

i've created a class having as private member a picturebox and a label.
I use this new object created in my application:
public class myObj
{
public Label mLabel = new Label();
public PictureBox mPictureBox = new PictureBox();
public myObj(Points myPoint)
{
....
myObj mObj = new myObj(lPoints); // set x, y of this new object
now i want add this to my form ( by this.controls.add(...) ) but i can't because it is not a control, how can i do?

You can't add it to the controls collection because your class doesn't inherit from Control. Since your just encapsulating normal Windows Forms controls, rewrite your class inheriting from UserControl. THen you'll be able to add it to the Controls collection.

I am used to VB.NET so this might be something stupid, but I can't seem to find a way to add System.Collection in C#.net after right clicking the references folder and selecting "add reference". I am trying to use a hash table but need the reference.
Thanks for the help

I believe it's there already, have you tried to just use it ?

hmm, maybe I should try  Ya I did try silly. For some reason on my home machine it is readily available. On the other machine it threw an error saying that it had to be referenced, but it was no where in the reference library.

According to MSDN, it's in Assembly: Mscorlib (in Mscorlib.dll).

Does anybody have sample code for using SSH/Telnet with the Sockets class (without purchasing a control)?

ok ... i am trying to create Custom Control (which later can be added to VS.NET tool box and added to any windows form). This custom control contains a data-grid. I want to implement the following functionality :
when user resizes this custom control he/she should be able to see control (i.e., data grid) resizing, like in the case of typical/intrinsic controls (text box). when we resize them ... we can see them their size changes.
second thing i want to do is that : as soon as this control is added to a windows form, a wizard is launched which allows customization.
i don't know how to implement this behavior... and where should i start?
any suggestions

How can i detect if a user has double-clicked the caption bar of a form (which normally causes the window to maximize)?
And is there a way to add icons in the upper left corner (left from the quit, maximize and minimize boxes)?

Okay I found the answer for my first question.

In this way i create a class inherited from PictureBox, but if i want that it inherit also from Label class what i have to write?
public class MyClass : PictureBox
{
...

You could use interfaces.. But you prolly need more then just a definition of members..

Im wishing to view all of the files in a document library in a tree view format. How can I do this? I have not found any controls at all in the API to assist me in my cause.

ronin,
I think what you are refering to is called the "Row Selector" or "Record Selector". If you are using Microsoft's built-in control, I do not think there is a way to this. Some 3rd party controls allow for this flexability but of course they cost money. Hopefully, Microsoft will add this in for VS2005.
