SendKeys - Beep - Suppress

Hello,

I'm invoking successive
SendKeys.SendWait("{BACKSPACE}")
SendKeys.SendWait("{DELETE}")
in a loop.

The issue is that it causes a Beep on every Pass.

Setting the 'Handled = True' on the Control does prevent the Beep, but
messes-up the Backspace-Delete Sequence.

Is there another way to prevent the Beep to occur?

TIA,

Michael

Well if possible don't use sendkeys. Are you doing sendkeys to your own
program? Can you explain a little why your doing, there may be a better
solution.

Well Chris it is indeed in our own program.
We have to use SendKeys on a TX TextControl v11.0.
The problem is TextControl can not programmatically remove a Paragraph.
The only way to acchieve this is by using SendKeys (though not recommended :-)

TextControl can thus 'Clear' the content of a line, but it can not remove
that line as a whole. It is like you're in Word and you have three lines:

Line One with text
Line Two with text
Line Three with text

You then want to remove line 2.
This can be done in code, but it results in:

Line One with text

Line Three with text

So what we then HAVE to do is select Line2, Col1 and perform:
SendKeys.SendWait("{BACKSPACE}")
SendKeys.SendWait("{DELETE}")

This results in:

Line One with text
Line Three with text

as desired.

TX TextControl will fix this in the next SP but that will be in 6 to 12
months?

Wel release our final candidate in a couple of days!
So we're really in trouble here.

SendKeys.SendWait "does" the job (as a workarround), even if it has to
delete 50 lines in a loop, BUT it triggers the Beep and that's real bad :-(

I was thinking about setting Mute On/Off (with checks and so on) but that's:

A: A bit drastic
B: Probably makes "the" mute-notification appear

I don't have any knowledge on stopping the beep, sorry. Can you set the
entire "TextControl" to something? If that the case you could make your
changes outside the the control and reset the Text property. Just an
idea, sorry.

Hi michael,

Thanks for your post.

I suspect that it is your 3rd party "TX TextControl v11.0." control caused
this beep. Because in my test project, the
SendKeys.SendWait("{BACKSPACE}")
SendKeys.SendWait("{DELETE}")
does not cause any beep for the standard textbox.

So I suggest you check if this problem occurs with the standard TextBox. If
not, I think you may have to contact the vendor company of "TX TextControl
v11.0." control for this issue.

Thanks

Hi guys,

Thanks both of you for your time on this issue.
We have indeed a case open at TX TextControl.
I do hope they come with a solution.

The problem is that it can't be - exactly - reproduced with a MS-Control
because before every 'SendKeys-Sequence' we Call a method on TX to remove a
'TextField'.
But it is the SendKeys that causes the Beeps.

Also making the changes in a StringBuilder is also not an option because (to
my knowledge) there's no way to retain the Document layout (meta-data) if you
use the Text-Property.

I guess in the mean time we have to use mute (how ugly a workarround it is)
to prevent the beeps from being audible :-(

Thanks!

Michael
 
Hi michael,

Thanks for your feedback.

Yes, I see your concern. However, because the problem lies in TX
TextControl, there is not much thing we can do to help you.

I have ever worked on an issue regarding getting rid of beep in standard
control, hope it may help you:
