Forms :: Trying To Coordinate Start And Stop Buttons
May 21, 2009
I'm very new to Visual Basic, and have just installed VB Express 2008 from a Sams book titled, "Teach Yourself Visual Basic 2008 in 24 Hours", by James Foxall. I've managed to make it through most of the book, which was very helpful in getting a quick jump start, but I find that I am still "not quite getting it" yet.
I've written a program that has a "Start" and "Stop" button which are suppose to control the logging of data through a serial port. When I click the Start button, the serial port gets initialized, opened, and then I go into a Do-Loop-Until loop to process the incoming data stream, and that is suppose to stop when the Stop button is pressed. However, I haven't figured out how to implement that.

I created 3 timers, i want each timer to take turn start which means timer1 stop then timer2 start, once timer2 stop timer3 start. But my code seem to be running together once i click the play button.And is there any ways to easy control how my picturebox move? Because my code for controlling it movement need to keep finding the correct number for it to move.

I am currently making a 2d game where a spaceship flies around a 2d map.Currently, I am moving the ship with keys, but would like to implement mouse clicking as well.I am wanting to enter an x and y coordinate and have the ship move to that coordinate.
These are my variables:
PlayerFacingAngle, PlayerPositionX, PlayerPositionY, PlayerVelocityX and PlayerVelocityY

I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

This code is in VB6, but I am not sure how to even start using it?

I have a form with a tab control on it. I've coded all of my button clicks, but for some reason when I do an F5, some of the buttons aren't working. If i go into the code I see the code for the onclick, but if I go back to the designer and click on one of the buttons, I get a new onclick section. Will the code for the button break if i move the buttons around the panels?

I have a USB interface connected to my PC which is used to control DC motors (robotics). Supplied with the interface is a VB program that produces a form with text inputs (motor speed) and tick boxes (motor on/off). This program calls upon a supplied .dll for the interface. I have played around with this program and have added extra buttons to 'stop all' or 'run two motors simultaneously' etc.What I really want to do is run a sequence of events, for example:
-Motor 1 on, speed 50, run time 5 seconds
-Motor 1 off for 2 seconds
-Motor 2 on etc, etc

what is the method to tell when a user starts or stops a process? My company makes a software package that allows a tie in from vb. I want to make a package to allow me to start and stop the software remotely and to monitor when the software is running or not.Ideally there would be some sort of event in windows when the user starts or stops the software. I imagine there is some sort of way to do this with a timer, but I am sure that windows will have some sort of event process when the program starts. I have googled this and looked through the xtremevbtalk forums for this but I am not quite sure as to what keywords to use.

I am writing a Windows Forms Application using Visual Studio 2008 Pro .NET version 3.5 with STRICT and EXPLICIT options both ON.
I am having trouble using ".Start()" and ".Stop()" for my stopwatch method from other methods. I have tried several different methods of writing the line that calls the start and stop, but none work, and VS keeps sending me in circles with its correction suggestions.
Form Level
vb
Imports System.Diagnostics
Class Level
[Code]....
and promptly gives me the same error with no options for correcting it. The same thing happens for the stop command.

Alright, I have form, with multiple buttons on it. I want it so when I Click on the Button that Says START it will Change to STOP but at the same time Enable all the Disabled Buttons on the Form. ATM I have this.
Dim ctl As Control = Me.GetNextControl(tbStudio, True)
Do Until ctl Is Nothing
If TypeOf ctl Is Button Then
If ctl.Enabled Then
[Code]...
Works Good, but when I add the btnStartStop.Text = "Start" or .Text = "Stop" to the If Statements, it's always getting stuck on "Stop" I also tried a Boolean statement but came out all funky, EVERY OTHER button was Disabled while the OTHERS were Enabled. I feel like a n00b, I've been programing for a bit now, but just got back into it,

Currently I have the start-key for my vb.net application hardcoded like this:
GetAsyncKeyState(Keys.F2)
Where vb.net sais "F2 As System.Windows.Forms.Keys = 113" on mouse-over.But I want my users to be able to pick their own Key. If I make a drop-down box (combobox) and pre-define some choices in there (Like ESC or F3), all those choices are strings. How can I convert those strings to a System.Windows.Forms.Keys integer? Also, I'd like it to also be possible to "capture" a single keypress. So they'd click the "capture" button, and the next key they hit will be saved as the start/stop button. But I wouldn't even know where to begin looking for that one.

I am a total newbie when it comes to VB but I'm starting off with a few simple projects I've completed already! Basically Ive seen MANY stopwatch tutorials but none so far have been able to do a simple format of Second and Milliseconds 00:00 and NONE have been accurate in the slightest and have been totally off! create a simple stop / start stopwatch that is actually accurate that would be great as Im going around in circles trying to find a tutorial on this!
