VB6: delay(100)

[Kuit_been]

Searched on google, but without any succes.
I need a function where I can define how long the PC has to wait until it
executes its next command.

I know that it is possible with a timer, but that gives some complications.
A timer goes through his commands & then waits 100ms before he goes through
his commands again, but if you call sth at the end of the timer, at first
time he goes through it, he won't wait for 100ms.

I found a function on the internet (kernel function: sleep 100), but in that
case, it waited 100 mseconds BEFORE doing anything:
txtInfo.text = "before sleep"
sleep 100
txtInfo2.text = "after sleep"
--> result = that it waits 100 ms and THEN it fills the 2 textboxes, even
the one that stands above the sleep command!

I found a function delay(100) in a dll: port.dll: that is to control the lpt
port, but that dll only works in win98, not in NT or XP. When I use the
function out of that dll, the PC hangs a while & I don't think any code is
executed then...


If anyone knows any command like I need, it would be wonderfull!
I need to write several data to the lpt port & after each command and data
send, has to wait 100ms, so I have to call that function more than once on
different places...

Big thanks in advance!

Re: delay(100)

try this. sleep value is miliseconds so 1000 for 1 second.


Public Declare Sub Sleep Lib "kernel32" (ByVal
dwMilliseconds As Long)


Sleep(1000)

The code line before the sleep did execute before the sleep, but the
display update it triggered did not.
You can force the screen update with DoEvents or Refresh:
txtInfo.text = "before sleep"
DoEvents
sleep 100
txtinfo2.text = "after sleep"

It is /not/ waiting 100ms before doing anything

txtInfo.text = "before sleep"
That generates a Windows message that will update the contents of
txtInfo
- but only when you let your App process it's message queue
- and since you are ungenerously hogging the current thread's
attention, it cannot process the message queue until you release it.

Try:
txtInfo.text = "before sleep"
DoEvents ' <--- process message queue
sleep 100
txtInfo2.text = "after sleep"

That will behave entirely differently
