Working on one screen & display on another

Hello,
I have a meeting next week where I'll be showing images, videos, etc. while people are talking in front of the crowd and I would like to be able to work on my MacBookPro but to have the items shown on the projector screen.
How can I do this?

That depends on how you mean "work on my MacBookPro but to have the items shown on the projector screen"
If you mean you want the same items that you are working on also shown on the projector, enable mirroring.
If you mean you want to work on some items while other items are shown on the projector, disable mirroring.

My ipod jumps from one screen / app to another on it's own. Sometimes I can't unlock or even shut off. I've tried the reset, I've tried back up, even tried restoring to factory settings and is still having problem. Any ideas of what I can do.

When you still have the problem after restoring to factory defaults/new iPod then you very likely have a hardware problem and an appointment a th Genius Bar of an Apple store is in order.

Why do i need to restart my imac everyday like ten times to get it to work, also the screen displays little digital squares.

Why do i need to restart my imac everyday like ten times to get it to work, also the screen displays little digital squares.

Hi Matt,
I purchased my imac in November of 2010 and below is a cut and past from Hardware overview. It has 1 TB hardrive, with 670 GB free. When i start up in the morning, it boots normal then freezes. Half the time i can get it to restart before it freezes, other half i have to power down then restart. At the same time throughout this process the little pixel squares show up sometimes in a single line or two aross the screen, then sometimes more random. After about 7 times of rebooting, everything runs fine for the day with no weird pixels. then i shut down at night, and start the porcess over in the morning. Thanks for your help!

Identical actionscript works in one frame but not another...?

Hi all,
I'm working on this electronic sheep creator for my Masters
degree (don't ask haha..) which is online at
[url]www.aegreen.co.uk/creativetech/[/url] . The problem I'm having
is that a piece of actionscript I'm using for saving the sheep as a
jpg using BitmapData works in one frame with one movie clip but not
in another frame..
In frame 1 I create two movie clips - mc_modifysheep and
mc_dna:
[CODE]on(release) {
_root.createEmptyMovieClip("mc_modifysheep", 1)
mc_modifysheep._x = 150;
mc_modifysheep._y = 70;
mc_modifysheep.attachMovie("sheep_body", "body", 1, {_x:42,
_y:65});
mc_modifysheep.attachMovie("sheep_head", "head", 2, {_x:0,
_y:0});
mc_modifysheep.attachMovie("sheep_legs", "legs", 3, {_x:77,
_y:215});
_global.bodycolour = "default";
_global.headcolour = "default";
_global.legscolour = "default";
_root.createEmptyMovieClip("mc_dna", 2)
mc_dna._x = 0;
mc_dna._y = 0;
mc_dna.attachMovie("mc_DNA_empty", "DNA empty", 1, {_x:8,
_y:360});
mc_dna.attachMovie("mc_dna_default_default_top", "top", 2,
{_x:45, _y:374});
mc_dna.attachMovie("mc_dna_default_default_right", "right",
3, {_x:65, _y:400});
mc_dna.attachMovie("mc_dna_default_default_left", "left", 4,
{_x:32, _y:401});
gotoandstop(2);
}[/CODE]
the sheep in 'mc_modifysheep' and the dna in 'mc_dna' are
built up over frames 2 and 3 and then in frame 4 the user decides
whether the sheep is given freedom or captivity. If freedom is
chosen then the user is prompted to name their sheep and the movie
clip mc_modifysheep is saved as a jpg on the server using
BitmapData and PHP. If captivity is chosen then the user is
prompted to name the dna and the movie clip mc_dna is meant to be
saved as a jpg on the server but only a white blank jpg is
produced, not what is contained in mc_dna.. I've tried all sorts
but I can't figure out why it's doing this..
Here's the code I'm using, that works, to save the
mc_modifysheep:
[CODE]import flash.display.BitmapData;
btn_freedom.onPress = function() {
freedom();
function freedom() {
snap_sheep = new BitmapData(305, 290);
snap_sheep.draw(mc_modifysheep);
var pixels:Array = new Array();
var w:Number = snap_sheep.width;
var h:Number = snap_sheep.height;
var a:Number = 0;
var sn:String = txt_Freedom.text;
high = 99999;
low = 00000;
ran =
Math.floor(Math.random()*(Number(high)+1-Number(low)))+Number(low);
var rn:Number = ran
var filename:String = dn+sn;
for (var a = 0; a <= w; a++) {
for (var b = 0; b <= h; b++) {
var tmp = snap_sheep.getPixel(a, b).toString(16);
pixels.push(tmp);
var freedomoutput:LoadVars = new LoadVars();
freedomoutput.img = pixels.toString();
freedomoutput.height = h;
freedomoutput.width = w;
freedomoutput.filename_sheep = filename;
freedomoutput.send("save_sheep.php", "_self", "POST");
stop();[/CODE]
and here's the near identical code apart from different
variable/movieclip names I'm using to try and save (but failing)
mc_dna:
[CODE]import flash.display.BitmapData;
btn_capt.onPress = function() {
capt();
function capt() {
snap_dna = new BitmapData(305, 290);
snap_dna.draw(mc_dna);
var pixels:Array = new Array();
var w:Number = snap_dna.width;
var h:Number = snap_dna.height;
var a:Number = 0;
var dn:String = txt_Capt.text;
high = 99999;
low = 00000;
ran =
Math.floor(Math.random()*(Number(high)+1-Number(low)))+Number(low);
var rn:Number = ran
var filename:String = dn+rn;
for (var a = 0; a <= w; a++) {
for (var b = 0; b <= h; b++) {
var tmp = snap_dna.getPixel(a, b).toString(16);
pixels.push(tmp);
var captoutput:LoadVars = new LoadVars();
captoutput.img = pixels.toString();
captoutput.height = h;
captoutput.width = w;
captoutput.filename_dna = filename;
captoutput.send("save_dna.php", "_self", "POST");
stop();[/CODE]
I know it's a problem with the flash and not the PHP as I've
tested for that, definately in the flash. I just don't understand
how the same code can capture mc_modifysheep, but not mc_dna.
argh!!!
If you need to take a look at the FLA file it's up at
[url]www.aegreen.co.uk/creativetech/dohumansdream.fla[/url]
Thanks everyone!!

If you dont find anything specific, a lot of the problems i
encounter like this are because one little thing is spelled wrong.
like it doesnt match whats in your php file, ect. my suggestion,
though a long one, if you know its supposed to work, and theres no
syntax error, re type it, not copy and paste, and just be careful.
keep tripple checking. you might not even find what was spelled
wrong, but it might fix the situation,

Two current input one can display while another cannot

Good evening everyone!
Our group is uing NI 9227 to get current from our circuit. But from the two indicators in front panel, as both of our two switches open, one can display current while another just shows 0.00....
But when I run circuit 2 independently in a new VI, it can display current normally...
Could anyone tell me why and how can I solve this problem??
Thanks so lot!!!

The VI you posted is quite messy and plenty of places for improvement but I am not convinced that this is the source of the problem. Why are you setting up your DAQ Assistance to be continuous sampling at 100 samples at 100Hz, but then you convert from the DDT to a single sample? If you really want a single sample then take a single sample. I'd also suggest not using the DAQ assistant because it can hide issues like this by using DDT. Still this should prevent you from seeing the right data.
It looks like you have current going into AI0 and AI3 of your device, are you sure this wiring is correct?
With a DMM can you confirm the correct readings going into the DAQ card?
Also you mention running a separate VI and having it work. I don't know how this is possible because one program will lock the current measuring device and not allow that resource to be used anywhere else. You should be generating errors. Which a simple error handler should show you. You should probably add that after the while loop stops.

Downloading a file via a procedure works in one app but not another

Obviously I've overlooked something. I have this procedure (following). It works in one application that has been running for a couple years. It is called from Column Link with this value #OWNER#.DOWNLOAD_ATTACHED_FILES?p_file=#DOWNLOAD_LINK#
I'm now making a new application and want the same facility but this same procedure gives me a page not found error even though the error page URL looks like: .../apex/GMCTRL.DOWNLOAD_ATTACHED_FILES?p_file=42 which seems to me that it should work correctly. (the row with the value 42 does exist in the DB)
Is there a setting/flag/thing that I have to set to make this work in my new application that I've overlooked? (both are APEX 3.1.1 and oracle 11g)
create or replace PROCEDURE "DOWNLOAD_ATTACHED_FILES" (p_file in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, RPT_DOCUMENT_BLOB_IMG, RPT_DOCUMENT_FILE_NAME_TX, DBMS_LOB.GETLENGTH(RPT_DOCUMENT_BLOB_IMG)
INTO v_mime, lob_loc,v_file_name,v_length
FROM RPT_DOCUMENT_BLOB

External monitor works only works when laptop screen displays

Hi there, I just connected a different (newer, but not brand new) external monitor to my T61. When I toggle screens (fn-f7) the external display gets no signal in the 'external display only' position, but displays beautifully in the 'both' position. This never happened with my old monitor. I would like to use the external display and not have the laptop screen display. Any ideas? Many thanks, Ellen

H
Try this:
After connecting external monitor, press win key+p and thrn choose projector only.

Implicit read with assembly module instance working on one computer, but not another

Hi,
I'm trying to set up an on-site computer to run a VI which uses assembly instances for data communication, but for some reason I'm unable to establish a connection to the PLC.
I'm running the example vi "CreateAssemblyInstance.vi" to try and get the communication set up before I start using my actual program.
When I run this code on my development machine, I'm able to establish a connection to the PLC and read data. I then go into RSLogix 5000 and change the IP address to the on-site machine and try to run the test VI there, but I'm unable to make a connection. LabVIEW-side, the program thinks that it's established a connection and is reading/writing data, but PLC-side I'm getting a "Connection Failed" message in RSLogix.
I find it weird that LabVIEW thinks the connection was established just fine, which the RSLogix says it can't connect to the VI.
Just wondering if anyone else has had this happen. We aren't sure why the same VI runs on one machine but not another. We used RSLogix to change the IP address of the target machine, so we don't think that's the issue. And both computers are on the same network, so we don't think it's a firewall issue either.
LabVIEW-side, things should be identical. I'm running the same example VI that came with the Ethernet/IP module. PLC-side, we're changing the target IP of the module within RSLogix 5000 (and we're sending the updated information to the PLC) to match the machine we're trying to make a connection with. Are we missing any steps? This is the first time we've tried using an assembly module, so we're having a hard time troubleshooting.
Any ideas on why this is happening?

I'm pretty sure we're using a generic ethernet module:
I can communicate explicitly with the problem computer, it's able to use 'Tag Read' and 'Tag Write' to communicate with the PLC.
We started having another problem just recently too. The Tag Read and Write commands are almost always timing out. I keep getting the error message -251723752:
Detailed error info: Error -251723752 occurred at EthernetIP Tag Read REAL.vi;Details: The request response was not received in the requested timeout period Possible reason(s): Ethernet/IP Industrial Protocol: (Hex 0xF0FF0018) The request response was not received in the requested timeout period
I can't figure out what's causing this all of a sudden, could these issues be related?

Home sharing works with one account but not another?

My family has an apple tv, we've been having problems setting up the home sharing and tried everything. We eventually decided to try my brother's apple id instead of my mother's and it worked. So my question is; why does home sharing not work with one id but works with the other? any suggestions to get it to work with my mother's id?

Try resetting the Apple TV. enter your mother's ID again. Then remove her ID on iTunes and re-add it. Then see if it works this time.

MultiServer Monitor Works on one PC and not another??

Super strange, but I have two PCs at my desk. On one of them I can log into a CF 8 server and bring up the MultiServer Monitor and add all my CF 8 Servers and it works great. On my other PC (the one I setup JUST to display the Monitor all day) it always says Permission Denied for all the servers. The server I connect to and the credentials used are identical in both cases. Also, both PCs are on the same subnet (not on the same subnet as the servers). Anyone got any ideas?? Notice that in both screen shots (one from each PCs browser) the URL is the same and I've keyed the username/password used on the failing workstation more than a dozen times to make sure I'm keying it correctly. I've even copied and pasted it so I know it is correct. Thanks for any input.

When you upgraded, did you remove the first install? I can't think of a reason off-hand, but have screwed up java before, and an update file may not overwrite the messed uyp part. just a thought, tah.

Same script..works in one form but in another keep getting "Date is not a constructor" error.

Using this javascript in one of my forms to timestamp it, (just a simple protected text field.)
form1.MainPage.DateTimeStamp::docReady - (JavaScript, client)
if (form1.MainPage.DateTimeStamp.rawValue == null) {
        var now = new Date();
        form1.MainPage.DateTimeStamp.rawValue = nowtoDateString() + now.toTimeString();
This timestamps the form as it should. The problem is on another form I'm building I'm using the identical script, (with different absolute paths of course,) and I keep getting a javascript error about date not being a constructor. I've type the script in ten bajillion times and I'm at a loss for what is causing this.
All I want is a simpel javascrip where I can display the time/date from the users system in a text field.

Hi,
You are missing a . inbetween "now" and "toDateString()"
Also you can simplify the script as it is in the docReady of the textfield:
if (this.rawValue == null)
     var now = new Date();
     this.rawValue = now.toDateString() + " " + now.toTimeString();
Hope tht helps,

Synaptics touchpad on 4540s works for one person but not another

The Synaptics touchpad on my ProBook 4540s (Win 7) works normally when I use it but when my wife tries to use it, the touchpad is unresponsive after a very slight initial cursor movement.  (Anticipating replies - Yes, she casts a shadow, pictures of her come out normally, and she has a visible reflection in a mirror.)     The touchpad sensitivity setting is maxed on light touch and cursor speed is maxed.
She has relatively small hands, and long nails, but she had no difficulty using the touchpad on our old HP dv9910us and has no problem with an iPad touchscreen.  This week she tried the touchpad on a Sony VAIO that was so worn most of the original surface coating is gone, and had no problem moving the cursor on that machine either.   She even tried the awkward solution of using her knuckle instead of her fingertip on the HP in case her nails were getting in the way, but that didn't work either.
Not having used a 4540s before, and not having access to another one to compare, I have no way to tell whether this is a bad individual touchpad unit or a design issue.   If a design issue, what's the workaround?     For instance, is there a skin I can put on the touchpad to increase its conductivity?

A friend of mine bought a ProBook 4540s yesterday. At Microcenter we noticed that the touch pad often would stop working for her, and sometimes for me, but it usually worked for me. She bought the laptop, and we she got it home we noticed the same problem. I played with the touchpad a little and noticed this pad has a very narrow window of operation. With the 14.1" HP's like the nc6220 or nc6400, you can use one finger, two fingers, even three fingers, and the mouse responds nicely. However if too much surface area is in contact with the touchpad of the 4540s it doesn't work. Too much surface area is the pad of your finger. Because my friend has long nails, she was laying her finger pretty flat on the touch pad, and it wouldn't work. When I used the pad like this it wouldn't work for me either. Because I have short finger nails I have always used the lower end of my tip. This works pretty well with the 4540s. Pressure seems to have little affect. It is a matter of surface area, and the acceptable area has a small range!

Safari works for one user but not another on same computer

MacBook with multiple user accounts. Safari (and Firefox) work fine for one user but are unable to open web pages when the other user is logged in. The error in Safar is "Safari can't open the page "http://xxxxxxxxx/" because it could not connect to the server "/xxxxxxx/" . DNS is working for this user. I am able to ping any number of sites from Terminal. Network Preference pane is configured to not require any proxy. This is a case of it was working but now it's not.
Can anybody help with this? I know I can fix this by simply creating another user and transfering the affected user's data to the new account but I would rather not. TIA

HI Bob,
You can test your settings by clicking the big "Test My DNS" button at <https://www.dns-oarc.net/oarc/services/dnsentropy>. If you see "Poor" on any of the tests, don't use that domain name server! Remove it from Apple Menu => System Preferences =>Network =>DNS Servers or similar location in your router if you've got a 'home network'. If all you have is "poor" DNS servers in your list, call your ISP and insist that they give you the address of a name server which is protected against the recently exposed DNS cache-poisoning threat.
Also, open System Preferences/Network. Click the DNS tab. Add these numbers in the DNS Servers box.

Can't Get Hyperlink To Work From One iWeb Site To Another

I created a "family" website, including a blog page. In a recent blog, I briefly announced that my two nieces just completed a two-week adventure in the African bush. I have created a second website using iWeb which is a simple photo page. I had hoped to hyperlink from my blog entry by saying that anyone interested in seeing the pictures of their trip "click here". I then used the Insert>Hyperlink>Choose dialog to place the URL of the second site as the hyperlink file.
No such luck. When the "click here" hyperlink is clicked in site #1 to navigate to site #2, all one gets is an error message.
Anyone have any ideas?
Desktop G4 Mac OS X (10.4.4)

I found out what I was doing wrong. In the hyperlink window I was trying to type in the URL for the second website on iWeb. Instead, there are pull down menus to permit the selection of another iWeb page or site as the link. It's working smoothly now.

Flash issues - works in one account, not in another.

Need help with any ideas on solving this issue.
I recently installed the latest official release of Flash Player 8. (8,0,24,0)
Then for some reason some sites doesn't display Flash content properly in Safari. My homepage for example (http://www.swedishboy.dk) doesn't work.
It sometimes loads the sound and the menu but not the "text" headline (it's text!!) nor the external swf file loaded into the first one. It all works smooth on Firefox and has worked on Safari before. In fact, on my fathers account on the very same iMac (G4) it works in Safari!!!
I've tried reseting Safari (bye bye all saved passwords), emptying cache, trashing Safari preferences, uninstalling Flash and installing it again (from my account) and still I get the same result. I give up. It seems to be a graphic issue with my account, any ideas?

swedishboy,
This is what I have listed in my Safari>Help>Installed Plugins Menu:
Shockwave Flash
Shockwave Flash 8.0 r24 — from file “Flash Player Enabler.plugin”.
What do you have listed in your installed plugins?
What results do you obtain when you check the Test Macromedia Shockwave & Flash Players link?
;~)
I just noticed that I have two of them listed...but the second one has a slightly different name:
Shockwave Flash
Shockwave Flash 8.0 r24 — from file “Flash Player.plugin”.
Perhaps someone else can explain that difference.
