I wish to be able to enter only positive or negative numbers into a textbox.How can I go about doing this? Is there any inherent vbmethods I can use with the textbox. I am currently able to restrict entries into the textbox to be positive number but have problems with the negative sign of the negative number. For example , I need to restrict the entry of the negative sign to be only possible as the first entry in the textbox but is unable to do so. How can I do this? Is it possible to know the cursor position in the textbox?

I thank you
