Hi C# experts

My inputbox appears on the task bar instead of appearing in the center;
i even tried this:
string s = Interaction.InputBox("Enter name", "Name", "", 100, 100);

I've just tried the InputBox function myself and, as expected, it works fine with C# 4.0 if you omit the last parameters.

However, if you're using an earlier version, the Type.Missing stuff doesn't work because the last two parameters are passed by value rather than by reference, as one might have expected for old VB stuff.

However, I did discover that the default value for those parameters is -1 and so this works fine:

string s = Interaction.InputBox("Enter name", "Name", "", -1, -1);

According to the documentation (http://msdn.microsoft.com/en-us/library/microsoft.visualbasic.interaction.inputbox.aspx), if you omit the 'xPos' and 'yPos' arguments, then the input box should be centered horizontally and one third down the screen.

If you're using C# 4.0 (VS 2010), which supports optional parameters, you should just be able to simply omit those parameters as you do in VB.

Otherwise, you'll probably have to do it like this:

object missing = Type.Missing;

string s = Interaction.InputBox("Enter name", "Name", "", ref missing, ref missing);

If that doesn't work, try it without the 'ref's.

Hey...we are not experts, we just coder and love coding. Every times we are not right.

Well, screen resolution is plays little complexity with inputbox here. You should try by asking resolution like 1024 x 768. then
