View 1 RepliesI come to programming from a school of functionality rather than theory- writing programs to meet a goal or solve a problem.I haven't had any education in computer science so many aspects of the Visual Studio world are alien to me.Just for fun I wrote a very small program to help with a computer game.It's called the All Lucky Sevens calculator for Final Fantasy 7.If you haven't played the game it won't make much sense to you so I'll eschew the logic of why I wrote it, focusing on what it does.
Basically it performs a series of percentage calculations on a number input by the user, trying to convert the original number into one that ends in 77. So 6104 reduced by 7% is 5677 The question is, how difficult is it to convert VB.NET code to work as a web-based app. I thought .NET was designed to make it easier to do this? Is it relatively simple to convert VB.NET code into something that can be run from a website? If not, the solution is to rewrite it in a different language like Java or Flash.The actual programming of it would not be difficult, but I do not speak those languages and it would require rewriting all the nested loops and ifs.Forcing VB to round down a decimal to an integer was difficult enough, I daren't think how hard it is in a language I've never used before.
Example: When you press "a" you want your program to automatically press again the same char you pressed. You know the e.KeyCode which is 65 for "a" and the command which is SendKeys.[code..]
Simple enough and it works for every character. But if you try it lets say with the Caps Lock button then the value of key is "CAPITAL"which means that the command will execute as follows:
[code..]
Which will obviously send the text "CAPITAL" not the key "Caps Lock".The same thing happens with % (Alt) and Is there another way to press a key without using the SendKeys function?
Don't stay on this:
When you press "a" you want your program to automatically press again the same char you pressed.
Cause that is not what i want to do.

I am new to VB and I have two detail listviews with one full of items that can be droppedinto the other. I have three groups in Listview1 and I would like different forms to open up based on the group each dropped item belongs to. I was able to open Form2 on drop by adding Form2.Show() at the end of the ListView_DragDrop handler sub, but this opens forevery item and I want different forms to open depending on the ListViewGroup the item belongs to.I set the items and groups in the property windows and not in code; I do not know if this makes a difference. So here is the code I have on Form 1 where the listviews are:Public Class Form1
