Take A String Apart One Character At A Time And Add Each Character To A Label?
Jun 13, 2010I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code:
ABinary = "0110 1100 0001 1011"

Read One Character At A Time From Keyboard?
Aug 31, 2009I am running Visual Basic Express 2005. I am trying to develop a program to send morse code out the serial port. I have created working code that can determine which character needs to be sent and toggles the RTS line on com 1 with the proper pulses. What I can't seem to figure out is how to be able to type in characters at a higher speed than they will be sent out the port, so as to be able to use the backspace key etc.

Displaying 8-bit Numbers From A Microcontroller In Real Time If Possible?
Apr 26, 2010I've already wrote a simple program for connecting to a serial port that can send data to the microcontroller, do some basic arithmatic and transmit it back to my Form. This was just to see if I could set up the conection.I have a PIC Microcontroller giving an 8-bit number thats is taken from an external sensor device.What I want to do now is to present this data from the microcontroller in a textbox as a number either in real time (as the sensor output changes) or if not possible, on request (using a button).
View 15 RepliesDisplaying A Series Of Images At Specified Time Interval?
Mar 12, 2012I am using Visual Basic 2008 for a Windows Form application. I have a PictureBox on the form that I need to display a series of 12 JPG files, one every four seconds. For the life of me, I cannot seem to figure out how to get the Timer control and its Click event to work.
In pseudo code, I need something as simple as the following:
1. show JPG #1 in picture box
2. 4 second delay
3. show JPG #2 in picture box
4. 4 second delay
etc.
I have a Timer on the Form set with Interval = 4000. I have a PictureBox. I have all the images in the Project. I am embarrassed to say that I have spent 4-5 hours searching the Web for sample code or something helpful, but am still stuck.
All the elements are there. It's just a matter of understanding how to pause the image displayed in the picturebox for 4 seconds before moving onto the next image in the series.

.NET And Displaying Real-time Received Serial Data On GUI?
May 24, 2010I'm having a bit of an issue receiving a stream of serial data and displaying the data real-time in my GUI. I am fairly new to VB.Here's what I'm trying to achieve: I have an I2C device (bank of LED's) connected to my Arduino. Using the VB.NET (2010) GUI I request which LED I want on (via buttons) and the I2C device then sends a reply confirming which LED actually turned on (basic feedback). Ok, sounds great right? Here's where I get issues. Well when I try to read the serial data sent to VB and display the real-time stream on the GUI, a) I get a bit of a mess as an output (values are ok, just spewn across GUI) and b) when I select a new LED to turn on, the GUI data does not refresh to this change. The stream being sent from the Arduino is ok, I looked at the data in a serial monitor.

Converting Time Formats Displaying In Label On Screen
Sep 24, 2009I have a variable which I called ElapsedTime. I press a button and it displays the time in seconds since clicking the button, into a label . I did it with HTML
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
LblElapsedTime1.Text = ElapsedTime
ElapsedTime = ElapsedTime + 1
End Sub
Private Sub BtnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnStart.Click
Timer2.Enabled = True
End Sub
This updates every second a bit like a simple stop watch. Great so far, because I do need the elapsed time (in seconds) for later use in my app. However, whilst elapsed time is being displayed in this label on the screen I want it to be shown in HH:MM:SS format. How can I convert it into a new variable " ElapsedTime2 " so that I can show it in the desired format yet still retain my original " ElapsedTime " variable for later.

Displaying Current "Real" Date And Time In Windows Form?
