Search within a string

Hello,

I wrote a program to allow users at my company to input custom values into their parts, assemblies, and drawings.  But I've found a small bug and can't seem to find any information on how to do fix this.

What it does:

When a user inputs a numerical value for "Price", the code adds a "\$" before it saves the property.  This ensures that the user will include a dollar symbol.  However, if there is a "\$" already there, it still adds one.

What I want it to do:

Check the string Price.Text before inserting the \$ and only include a \$ if it's missing.

I just can't figure out how to check the first letter of the string and compare that to \$.  I assume I need an If Then statement.  Any help would be greatly appreciated.

Thanks,

Tara

P.S. I'm using Solidworks 2010 x64 bit
