I would like to show that the computer is busy and not frozen during a long file transmitted over Serial Port.I have the following loop.The intention was to show one "*" for every line sent.
While (fs.EndOfStream = False)
lineRead = (fs.ReadLine)
TextBox1.Text = "* "
SerialPort1.Write(lineRead)
End While
I can see the data sent on the Scope but the chain of "******...." show up after the transmission ends.The WHILE LOOP is actually working but the TextBox1.Text = "*" is not writing to screen.I would like to see the train of ******** same time as the transmission is active.The * is to show that the computer is busy and not frozen.Writing a copy of the actual serial data transmitted to screen is also another option that I can use.

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

View 3 RepliesI'm working on a project that employs a masked text box with a mask ####. When I run the code it pulls the value from the textbox then clears it. When I try to type in it again the first character is added before the mask. (ex. 1#### instead of ####) I've figured out that pressing backspace before trying to enter numbers again resolves this issue. Is there a way to send the backspace function rather than the chrs(8) like SendKeys.Send(Keys.Back) does?
