View 3 RepliesStop Execution Of A Program Without Ending Application?
Jun 15, 2011I have written a converting program, which converts binary files to ASCII files. (VB.net 2010). I need to have a functional "stop" button on the form and I was wondering if there was a simple command to make a program stop, exit all procedures, and wait for user input on the form.
It is not feasible to multithread this application, as it frequently interfaces with the form. Currently, I have a global boolean variable which becomes true if the stop button is pressed, and I have internal loops checking to see if the variable is true. However, I don't to waste CPU on checking a variable if it's not necessary.
Ending A Program With "END"
Mar 19, 2009In VB6, I've learned why I should not used "END" to close or terminate a program. Does that rule still applies to VB .NET? (.NET 2003 if that makes any difference)
What is a proper way to close a VB NET program while ensuring that all forms that are either visible and or invisible at the time of termination gets unloaded from memeory, and all used resources gets released?

Ending Application From DLL Subroutine?
Feb 23, 2010I'm writing a class library and I need to be able to shut down the main code in certain cases.
I know I could raise an event and listen for it in the form called by application.run but I would like to find a way around it.I wouldn't be opposed to try to throw an exception that if unhandled would close the application... but would prefer to come up with a more elegant soln.
ShowDialog Form Not Ending
Nov 4, 2010I converted this app from VB6. I have 2 forms. Form1 instantiates Form2 via a Menu Item.I am having trouble getting Form2 to end when clicking close (X). If Form2 is 'idle' it closes fine; but if I am in a loop processing anything all the events fire, but it continues processing in Form2. I've tried messing with Dispose, Close, Application.Exit, Application.ExitThread. My last attempt was creating my own event to fire back to Form1 and dispose Form2 -- and it hits it but Form2 is still running. What is the deal? BTW if I use just Show vs ShowDialog -- Form2 just blinks and disappears.[code]

Forms :: Input Starting And Ending Time
Nov 2, 2009I want to make a very small program where the user inputs a starting time and an ending time that is in "clock time (?)" and the program converts it to total minutes in one box and a decimal total in a second box. I have 4 textboxes, 2 are masked text boxes (military time) for input and two are not, for output and the math is coming out weird.
If I put a start time of 0925 and an end time of 1015, the results I'm expecting would be 50 total minutes and .83333 total as a decimal. I don't think I'm converting the textbox input correctly as I'm not getting anything near that. I am using a button to calculate and another to clear the boxes, just FYI. Also, I'm not sure what to do about any times that span the noon hour except to use an absolute value.
Public Function Time()
Dim StartTime As Double
Dim Endtime As Double
StartTime = txtStart.Text
Endtime = txtEnd.Text
txtDecimal.Text = (Endtime - StartTime) / 60
txtMinutes.Text = Endtime - StartTime
End Function

Unexpected Result Of RTF Line Ending Conversion
Jul 8, 2011If txtLog is a RichTextBox control:
Dim text = "hi" & vbCrLf
Debug.WriteLine("t:" & text.Length) ' --> 4, as expected
txtLog.Text = text
Debug.WriteLine("tL:" & txtLog.TextLength) ' --> 3. muh?! :(
Having looked at the RTF spec, the end of a paragraph is notated as par, which is neither CR nor LF. This makes sense since RTF is markup language; like in HTML, line endings have little meaning on their own.
So presumably, on writing into the RichTextBox, my line ending is being encoded into par. And then, on extraction, the par is being translated back to a real line ending for use.
It turns out that this line ending is vbLf.
Why, since Microsoft near-consistently employ CRLF for line endings, would RichTextBox translate par to vbLf instead of vbCrLf?
