I need to delete the first character on EACH line, IF it is a space. JUST the first character, since I have other spaces in other parts on that line. The stuff will be in a textbox. This is probably really simple. But, me being a noob, only found how to delete the first letter of a string, not a text file, while searching google.

My issue is that some websites only allow say 15 characters maximum to be used to create a user name where other sites do not. Currently I have one text box on the screen and a button, and a web browser that navigates to two sites.Site #1 has a cap of 15 characters max to create a user nameSite #2 doesn't have any maximum amount of characters to use.I am wanting to know how I can enter lets say a 20 character username into the text box and have the code set a max of 15 characters for site one and nothing for site 2. I was thinking that this could be done when passing the information from the text box to the text box on the screen with something like
Textbox1.Text.value.length= maximum 15
Site #2:
Textbox1.Text
