Problem with Viewsonic VX2025 display and PowerPC G5
I recently switched from an old G4 tower to a less-old G5 tower with dual 2GHz processor and a GeForce 6600LE graphics card. The monitor I was using with the G4 is a Viewsonic VX2025, and they worked flawlessly together. Not so much for the G5. The monitor, which is connected via one of the two DVI ports on the G5, works when the computer is started cold. However, after a period of inactivity or sleep, the monitor goes black and will not receive a signal. The power to the monitor remains on, but the light on the monitor is yellow. If I tap the keyboard or click the mouse I can hear the tower powering up, and my mouse will flash its light, but the monitor will remain black. At this point I will have to power down via the power button. Occasionally, however, the G5 will not power down and I'll have to disconnect the power source. At this point turning the computer back on will result in the same black monitor screen unless I wait at least 20 minutes to turn it back on. In which case, everything will work fine as long as it doesn't go to sleep.
I've tried re-seating the power cord for the monitor, and checking the connections.
Now, I've switched to an old VGA monitor that I dug up from the garage with a DVI adaptor. This system works fine and I've had no problems. However, the monitor quality isn't very good and I need to figure out a way to get the G5 working with my Viewsonic. Any suggestions?
I have a Power MacG5 behaving exactly the same way with a large Westinghouse (LCM.22W) LCD Monitor. The problems began when I decided to enable the sleep function to save electricity. For years it worked fine and the sleep problems into an unwakable black screen started on and off with me doing the same to remedy it: restarting or unplugging and replugging the DVI 400 cable (Monster Digital Video)from the CPU DVI port. Now nothing works as a remedy. I have no alternate monitor to use to access the CPU. Now when I reseat the DVI cable the monitor says check connections indicating it isn't hooked up to a DVI output video source even though it is.
I'm starting to wonder if the problem is the G5 video card in the CPU and not the cable or the monitor since I'm not the only one who has experienced the problem with a large monitor when the computer goes to sleep and the monitor shuts down.

Detect Displays problem with ViewSonic VX2035 - VGA and Snow Leopard 10.6.6
I just bought a KVM switch (IOGEAR GCS72U) so that my ViewSonic VX2035WM can jump between my macbook (where it is an external monitor) and a linux box that I built. The monitor worked fine with the macbook, always detected automatically or by the "Detect Displays" button - before I switched from a DVI connection to a VGA connection. I had to switch to VGA to facilitate the KVM switch. The monitor has a separate built-in VGA input and built-in detection of analog versus digital input.
Now that I have setup the KVM switch and VGA connection - using appropriate Apple mini-DVI-2-VGA adapter - Snow Leopard detects that a monitor is connected, but only generically as "Display" instead of naming the display model (ViewSonic VX2035WM). Display Preferences does not provide the optimal resolution (in this case, 1680 x 1050), with the closes being 1400 x 1050, resulting in a distorted picture.
http://www.viewsonic.com/products/desktop-monitors/lcd/x-series/k
The KVM switch is listed as being compatible with Mac OS X, and supports resolutions up to 2048x1536.
I do see a picture. It does detect that a monitor is there. It does not recognize what kind of monitor it actually is, and it does not allow me to select the resolution/frequency settings that I actually need.
When I skip the switch and connect directly from the Apple VGA adapter to the built-in VGA input, the problem is exactly the same. No amount of putting the laptop to sleep, turning monitor off, clicking Detect Displays, is getting anything to change. An option to manually specific the resolution and monitor would be fine. At this point I would even be willing to pull a "Windows" and install a driver, so long as the problem is fixed. I'm pretty sure the appropriate driver is already included in Snow Leopard, because it was working fine and recognized this model before I switched from DVI to VGA connections.Using the printerto manage color is worse, still magenta cast, or gray/browns. We've tried all the different settings withing Photoshop Color Setting, we've tried all the different combinations within the printer window dialogue, all either have a magenta cast or red cast...we've tried different combinations with photo papers...what is interesting is with no change in any settings if we use plain copier paper with the medium selected for Plain Paper the colors are truer but because of paper quality the image is not good enough. I'm thinking it may be something within settings for paper and ink. But since I am not techically savy enough to understand all of the color management settings we've relied just on the internal settings and only had to change the medium paper quality to get good images. Once I upgradedto Snow Leopard it appears I have to be more sophisticated in color management. At a loss. What we're going to try now is change out all the inks to fresh Canon inks, and recalibrate monitor (which I did before but maybe needs again) and try and match a Pantone Color Guide to set monitor, and experiment with paper combos...if that doesn't work quess I have to bring in some tech help....we're designers and graphic artists so havng a hard copy for clients is crucial. Thank you for any help.

Problems with ViewSonic LCD displays?
I have a ViewSonic VP2030b 21.5" LCD monitor hooked up to my G4 DA. The
monitor works OK with these two exceptions:
1. "About This Mac" info on Displays consistently says "No display detected".
2. I frequently have to restart the G4 several times to get the monitor to respond
and light up. Once it's finally on, it works fine.
The installation software that comes with the monitor installs only onto my OS9
volume, not onto OSX. Since the monitor dates from 2005, it should be
compatible with at least the earlier version of OSX. I inquired about any
update software at ViewSonic and was told that my install CD is the latest
version they have for Mac.
Is anyone using a ViewSonic LCD monitor having similar problems?What does it say in System Preferences > Displays? What if you click the "Detect Displays" button there?
My Mac has a card that supports two displays. It reports the correct info for the first one, then underneath, with no break, says "No Display Detected". In my case, I know it is talking about the second display, which is correctly identified as not connected since I only have one.
Most displays do not need any additional driver software on the Mac, so do not be alarmed if that CD will not install.
What graphics card is this? -

IE11 Problem with Windows 8.1 and IIS 8.5
I have upgraded my computer from Windows 8 to Windows 8.1, 64bit and IIS 8.5 is installed on the upgraded machine. I am unable to view with IE11 the default page of the default website hosted on the local machine. The problem occurs with both
the desktop version of IE11 and the Windows 8 metro style version.
When Chrome is installed on the machine the page is visible but when using IE11 a "This page can't be displayed" message appears. The IIS Log Files reveal that it is receiving nothing from IE11. Other machines I have that have also been upgraded
to Windows 8.1 exhibit the same fault.
The strange thing is that when viewing pages on other networked machines exhibiting the same problem, you can see the pages on the remote machines but in all instances the local page cannot be viewed.
It appears that there is a problem with IE11. Uninstalling and reinstalling IE11 does not fix the problem.
Can anyone help me? Assitance with this problem would be most appreciated.Description

Problem with Indesign CC 2014 and tables
Problem with Indesign CC 2014 and tables. The text rearranges itself when I delete or add something in a table; the footnotes to the text associated with the overlap even getting unreadable. Just click on the chain symbol in the window and everything is fine. Why?
try circumventing your cc app and see if that helps:
if you follow all 7 steps you can directly download a trial here: Adobe CC 2014 Direct Download Links: Creative Cloud 2014 Release | ProDesignTools
if you have a problem starting the download, you didn't follow all 7 steps, or your browser does not accept cookies.
the most common problem is caused by failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com).
failure to obtain that cookie results in an error page being displayed after clicking a link on prodesigntools.com or initiates the download of an incorrect (eg, current) version. -
Problem with hotmail calendar display
Problems with hotmail calendar display.
I am almost a total computer novice and am having what I think is the same problem Just got my first Apple computer (Macbook Pro). MSN Hotmail is my email account. All the events on my 'hotmail' account are now unreadble because they are squished to the left side of the screen and I don't find any instructions as to how to fix this in the system. This problem didn't exist when I first started using my MAC two days ago, but now I'm stuck. Everything else in my 'hotmail' seems to work fine. Don't know what Chrome or Firefox is or if there is a cost for them. Also, have never downloaded a program if any kind.
My calendar is critically important to me and I don't have a clue as to what to do now. Hope you can help.
Thanks. Linda -
Wireless printing problems with 10.5.4 and Epson printers
Anyone else know about problems with Epson printers such as this no longer functioning wirelessly with bonjour once upgrade to 10.5.4? It appears they are not supporting this with a new driver yet?
At this time, Epson says they have no drivers for 10.5 and this specific printer but wondered if there are more general problems with 10.5.4 and bonjour with Epson or others?
Thanks
Paul
MacBook Pro Mac OS X (10.5.4) Using Epson CX11-NF printerI have 5 computers-G4 PowerPC, two G4 12" laptops, G5 Mac Pro dual, Macbook Pro--with the older computers all running 10.4.11, the new ones 10.5.4. Until Friday, I was able to print with all of them to an Epson Stylus Photo R200 via Airport Extreme. After installing software for my new G3 iPhone on the G5 Mac Pro the printer connections on all the computers stopped working. I have so far been able to get the G4 Power PC to print, but none of the others. I have tried Bonjour, Gimp-print v.5.0.0-beta 2, cleared all the print drivers and restarted, and everything else I have been able to find on both Epson and Apple sites. The Printer Set Utility described by Epson does not exist in Leopard machines, and doesn't work for the older laptops. As soon as I select one of the printers in the "selected printer in print dialogue box" it grays out. I have set up sharing on the G4Power PC that does print, but it is not accessible--it shows up but is grayed out. There is a diamond next to the printers in the Print dialogue box in applications' menus, but it still doesn't work. It either cannot make the connection, cannot find the printer, or keeps spinning with the message that it is finishing printing (but it hasn't even started.) Again, everything worked fine until the new iPhone was added to the mix. My old iPhone didn't cause any problems. This is really a problem. Any suggestions welcome.

Problems with LabVIEW 7.1 and lock-in amplifier Stanford SR530?
Does has anybody had problems with LabVIEW 7.1 and the instrument driver for the lock-in amplifier Stanford SR530?
With LabVIEW 6 there are no problems at all, but with LabVIEW 7.1 it is impossible to communicate with the instrument.amr_attia wrote: (Private message, no need to private message)
My problem is to get the data out from the divice x and y readings . Can you help me
Here is the code and snippet. I had it from before. It reads Channel 1 and Channel 2 from the SR530, that is whatever the display is for Channel 1 & 2. You set the display manually or programmatically, I let you figure that part out.

After having yet another problem with my MacBook Pro and having to wipe the drive, I am now unable to sync my iPhones etc without erasing all the music on them. Is there a way around this? I have no other library!
iTunes is a mess! It couldn't find it's own libraries and I was forced to create a new one. Now I don't know where my music is or if any's missing.columbus new boy wrote:
How crap is that?
It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer. -
I tried downloading a free app and it asked for my billing information and when I entered it, it said that there was a billing problem with a previous purchase and I have to update it. I keep updating it and it wont let me verify it and I cant get any apps even if they are free, and I just Deleted some apps to make room for my new upate!
The message says: "The payment method has been denied, try another method"
I'm living in the same country and city since I was born, so I don't think the location is the problem.
And yes, I paid with the card a meal in Burguer King today. And nothing more. -
I have been trying to download apps from the app store and every time it tells me there is a problem with my previous billing and direct me to put in new billing information and every time i do that it still will not let me download any apps.

Communication problem with Adobe 9.0 and HP Printer when I scan

Problem with java swing button and loop
Problem with java swing button and loop
I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
When I click on start button it must do next:
Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
And when I click on stop button it must do next:
Start button must set enabled and selected and Stop button must set disenabled.
Field status is set to 0.
This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
There is java code, so you can get better picture:
/** start button */
public void gStart_ActionEvents() {
try {
ivjGStart.setEnabled(false);
ivjGStop.setEnabled(true);
ivjGStop.setSelected(true);
getJTextPane1().setText("Program is running ...");
Status = 1;
} catch (Exception e) {}
/** stop button */
public void gStop_ActionEvents() {
try {
ivjGStart.setEnabled(true);
ivjGStart.setSelected(true);
ivjGStop.setEnabled(false);
getJTextPane1().setText("Program is NOT running ...");
Status = 0;
} catch (Exception e) {
/** procedure IzvajajNeprekinjeno() */
public void IzvajajNeprekinjeno() { //RunLoop
try {
int zamik = 2000; //delay
do {
Thread.sleep(zamik);
PreberiDat(); //procedure
} while (Status == 1);
} catch (Exception e) {
So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
Any help will be appreciated.
Best regards,
TomiThis is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
Since java is task-based this will happen if you do like this:
1. Button "Start" is pressed. Thread running: GUI_Thread
2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
5. Call PreberiDat(). Thread running: GUI_Thread
6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.
