Method BitmapData lock does not work.

import flash.display.BitmapData;

Import 12345678910111213import;

import flash.geom.Rectangle;

var bmd:BitmapData = new BitmapData (100, 100, false, 0xFF0000);

var bitmap: Bitmap = new Bitmap (bmd);

addChild (bitmap);

BMD. Lock();

for (var i: uint = 0; i < 50; i ++)

{

for (var j: uint = 0; j < 50; j ++)

{

bmd.setPixel (i + 25, j + 25, Math.Random () * 0xFFFFFF);

}

}

I don't don't see random colors in the red centre of rect, but I see it. What I've done wrong?

but you tell him to show here the random colors

Math.Random () * 0xFFFFFF

Yes

bmd.setPixel (i + 25, j + 25, Math.Random () * 0xFFFFFF);

random sets pixels in its bitmapdata

However the previous call to

BMD. Lock()

We hear content on the bitmapdata should change, but the bitmap object should not be updated until that bmd.unlock () is called (which, in this example, it is not)

Lucky: I'm looking into it, and I don't see why it wouldn't I'll try and get back to you unnecessarily, it should work

  • HP Pavilion Notebook 15-n225se: Cap lock does not work

    Hello everyone

    The cover lock does not work, or no led light upward.  She went to work, to work from time to time and now not al all.

    Because passwords often have caps there is problem enough.

    So I use the virtual key boad for the lids and the normal key Board for everything else.

    Only a short-term solution, however.

  • BitmapData.Draw () does not work with crossdomain images

    We develop a gallery of dynamic moving images using Flash 8 & AS2, for which images are called from another area. I used the Reflection class (in which bitmapdata.draw () of works) to achieve reflections. It works fine when the images are called from the same domain. But when the images are called from another area, the Reflection class does not work because bitmapdata.draw () does not work on images of crossdomain due to security sandbox. Although the images are appearing. I would be very grateful if anyone can answer, because I tried this for the last few days with little success.

  • indicator of Caps lock does not work

    My caps lock indicator windows stopped working a while ago and then I turned on toggle keys .but it has also stopped working. I am using windows 7 ultimate.the characteristic toggle key is on but it still does not work, I tried to put it and the but its still not working.i also tired ms fix the app but it did not find the problem. I would have preferred using ToggleKeys indicator, but both will do the job.

    Microsoft does not have any indicator, only the ToggleKeys.  Windows itself has never had such a feature.  You must use another program on your old computer, perhaps a program you downloaded from the Internet or a program that your computer manufacturer preinstalled for you.  Sony installs keyboard for example indicators and I think Dell has on some of their computers.  But he has never been a built-in feature.

    You can try a small program like this:

    I enabled the functionality of group-lock on a group of C2L VPN but the ASA does not add the tunnel-group-name value in the RADIUS packet sent to the server for authorization.

  • Number lock does not work under windows 8.1

    I have an Acer laptop Aspire E1-522 using windows 8.1.  When that I start, the keypad works because I can log on the computer by using the keypad.  Once I am 'welcomed' trying to enter data on the Microsoft Office program (Word, Access, Excel, Notepad etc.) the keypad does not work.

    Every search I did leads me to some company trying to sell me programs to solve the problem.

    Word and Excel displays Num Lock indicators in the lower status bar?

    You must right click on the color bar to activate it (right click on where the red dot is, and then turn on Num Lock).

    After that, Excel will tell you if the NUMLOCK is considered by the program, with a power indicator near the left:

  • Light of CAPS LOCK does not work

    Hello dear guys,

    Had a problem today - some keys on the keyboard do not work properly.

    I opened the hood of the laptop (Pavilion G6 2241sa) and saw that the keyboard cable was loose. I reconnected properly, closed the lid and turned on the laptop. Now, all the keys work well, BUT the CAps Lock light doesn't work well. Key works, but when I press on it - will light, but as soon as I release the button - the light turns off. Light is not. Also, when the real function of the caps lock is on, when I press another button, the light on the surface of the NumLock key but it is dim.

    I recheched cable keyboard again - everything is fine, but seeing locking caps does not stay when you press.

    I don't practice typing for the last 3 months for a few hours a day, so I guess that it also affects the life expectancy of my keyboard.

    Would appreciate any insights on this light lock thanks a lot, lives

    Thank you for your response. But the General solutions do not work here, I'm afraid.

    My inner voice tells me that it is the problem of specif inside wiring that cannot be fixed, perhaps only by the replacement of the entire keyboard or keyboard cable.

    I appreciated your help in any case. My keyboard works, light Verr Maj is not so important, that's why I will end this matter as resolved. Cheers, lives

  • Search iPhone settings for "Auto-Lock" does not work

    Hello

    Does anyone know why the Auto-Lock setting is not to be found when you use the search at the top of the main settings page.

    From time to time, when I'm on a conference call, I like to set the auto-lock on 'Never', so I can leave the visible main phone screen to mute/one-mute the call without having to unlock the phone. I have the memory of a goldfish, so I do not remember that it is in the section "Viewing and brightness" and that is why I use the search at the top of the main settings page field. I would normally enter 'Auto', and it would be "Auto-Lock" for me.

    Since the release of iOS10, the la recherche search can't find this definition more although it still is in the section "viewing and brightness.

    The search for other settings seems to work, but it seems that it is just this one, but I have not actually tried too.

    Any ideas on what is happening and how I could get to find the Auto-Lock in the future?

    Thank you

  • I want to turn the spelling checker in Waterfox, but the method for Firefox does not work?

    I added my language in the options and set it as your preference and ticked "check my spelling as I type", but I KEEP getting the spelling English-Checker when typing on a certain forum. And I type in Dutch, so it is very difficult to read with almost all the underlined words...

    So, I can't put it in my mother tongue, and I can't turn him completely. Either one would be great...

    I've been loolking for a way to show that this issue concerns WATERfox, not FIREfox, but somehow there is no separate place to do...

    The global setting to turn off all THE spell checking in Firefox is here:

    "3-bar" menu button (or tools) > Options > advanced > general mini-onglet > "Check my spelling as I type".

    You say it doesn't work?

    Note that the already loaded pages are not affected by the change, only the pages that load after that you activate the setting. So if you want to stop the spell check on the current page, you need to recharge after changing the setting.
