A simple method like this should do it:

public string ToHexstring(byte[] byteArray)
{
    if (byteArray.Length > 0)
    {
        StringBuilder resultBuilder = new StringBuilder();
        foreach (byte value in byteArray)
            resultBuilder.Append(value.ToString("X2"));
        return resultBuilder.ToString();
    }
    else
        return "00";
}

cut,copy,paste a picturebox control in c#.net at runtime

The mear fact that a number is being displayed in the DGV makes the item you see in the DGV cell a string, no matter what the actual data type is. So, no there's no way of displayed any data in a DGV without converting it to a string, or some other custom rendered display.

Now, as to answer the darned question;

A PictureBox is a place-holder for a picture, in the same way that a label is a placeholder for text. Both don't have the cut/copy/paste functions, because they aren't editable.

A Textbox is the placeholder for text that can be edited. There is no placeholder for editable pictures.

In other words, what is supposed to happen when you "cut" something from the PictureBox? Should it remove the entire picture, or just a selection thereof? The first "cut"-mechanism is easy to implement, as you just need to assign "null" to the image of the picturebox. The second "cut"-mechanism is harder to code.

What about "paste"? Do you want to insert a new picture in the picturebox, or do you want to combine the picture with what you are pasting?

Please advise.

.dat is typically a generic file extension used to denote that it is an internal format for some application. We cannot know the format unless we know the application to which it belongs.

You can open the file using a FileStream and a BinaryReader, but you'll need to know how it is formatted internally to be able to interpret what you get back.

Setup tool

I had very little experience with creating setup projects. If i remember well, the Publish tool from VS creates a MSI file, that installs the application, but does not allow the user to specify an installation path or other options. This is called Click Once deployment, right?

What I need is an installer which will allow the user to specify an installation path. What do you recommend? (preferably free). Thanks.

What about the Setup Project already in Visual Studio?

Hmmm, if that does what I need I should start learning how to use it. I somehow had the impression that Setup Project was doing the same thing as the Publish Tool. Thanks.

As Colin said, use the one built into Visual Studio. If you're using an express edition which doesn't have this, there's always Inno Setup[^].
