You can always use
xhost + localhost
But the real solution lies here...

Getting error when trying to launch a game through game center

I am trying to launch Pinball HD from Game Center but always get connection errors. For instance, I receives the error "The requested operation could not be completed due to an error communicating with the server". I am also getting "a server with the specified hostname could not be found"
I am connecting through Wi-Fi. Any particular setting I need to specify in my router?

Wow. Did not expect an answer so fast! Unfortunately for me, the progress indicator keeps spinning for a long time before it comes back with an error. My internet connection is working. Is there a way to know what server it tries to connect to. I could probably run some tracing tools from there.

Why do I get the 'PowerPC code' error when trying to launch an Intel-based app from a CD?

When trying to launch a Flash-based app from a CD on my Mac Book Pro, I get the "PowerPC apps are no longer supported" error. Yet the app is not built with PowerPC code.
This also happened with Microsoft Office programs soon after I upgraded to OSX Lion, but someone was able to solve that for me.

It's just a free disc from a photo magazine, but the app runs fine on a Mac Pro running 10.7.3. Could it be hardware related?
I have actually asked this on behalf of a reader (I work for the company that makes the magazine) who is experiencing this problem, I just can't find any reason why the error would display in these circumstances. I apologise if this is against the community's usual practise - I just want to sort this guy out!
The app on the disc is compiled using MDM Zinc, but like I said it runs a-OK on Lion everywhere else.
Any help would be gratefully received and appreciated!

Getting error when trying to open Job Manager

Hi List
we are getting the below error when trying to open the Job Manager,which worked fine until yesterday.

Please advice.
Thanks..

Did you change your JDK path by any chance? Also you are getting a strange error message. It is trying to point to both D:\OracleBIData\jobmanager and C:\OracleBIData\jobmanager. Is there anything that you changed prior to doing this?
Thanks,

Error when trying to launch iTunes! Help!

Hi!
I've tried to seek through the forums to find someone with the same error, but i haven't found anyone.
Here's the problem:
When i try to launch iTunes I get a Windows Error saying that iTunes har encountered a problem and has to quit. It's that kind of error where you can send an error-report. And when I try to restart Windows, I get the same error when I log on. Please help! I've tried to reintall and repair iTunes, but it won't help.

hi
I had this same problem for ages and tried all sorts
of things. I think the problem was Quicktime
actually, but what eventually worked was:-
Uninstall itunes, then reboot. Close the Quicktime
program tray icon (lower right corner of taskbar) and
uninstall Quicktime. Then install the standalone of
Quicktime before installing itunes again.
Hope this helps.
Thanks!
I'll try it out! Havent't thought of that.
Will come back to say if it worked.

Getting error when trying to download update for flash player with OSX 10.91

Trying everything to download update for Adobe Flash Player. This is maddening. I have tried uninstalling previous player and re-installing and checked my preferences. Can any one give me some instructions that are easy to understand. I keep getting an error when installing.

There usually is an Adobe flash uninstaller that goes through a process satisfactorily.
Did you get the Adobe Flash update from their
page, directly? http://get.adobe.com/flashplayer/
Also note the extensive info at Adobe link below.
If you are having trouble, or Safari is involved, if
you use a different browser, such as Firefox, etc to
get that version Flash update. There's another thing to
look into, in Mavericks, that older OS X didn't
have, that may affect installation...
In System Preferences, find a Flash Player preference
under "Other." Click on the Advanced tab and then "Check
Now" in the Updates section. An available new one
would be installed. There is a similar issue/answer
in the following solved ASC discussion thread:
https://discussions.apple.com/message/21189654#21189654
•Adobe Flash Player - Installation Problems - Mac OS X:

Hopefully this helps.
Good luck & happy computing!

As I did not want to solve it dirty as Thorsten Reinbold did to build his package I downgraded automake from 1.15 to 1.14 temporarily and built the package with no errors. I then installed the package and all is working properly. I then reupgraded to version 1.15.

Always getting errors when trying to control YOKOGAWA 7651 power supply on Labwindows/CVI

Hi,
I'm trying to set the voltage on the YOKOGAWA 7651 power supply through labwindows/cvi. I've set up a numeric slide on my userinterface with callback function "yoko7651dcvolts" and constant name "YOKO7651DCVOLTS".
I always get this error when I run my program:
"FATAL RUN-TIME ERROR: "DcSource.c", line 53, col 65, thread id 0x00001F3C: Invalid argument type: found 'pointer to double', expected 'pointer to int'."
This error points to the third argument of the GetCtrlVal function below. The program/compiler wants me pass the variable "yoko1volts" as integer, but I want to (and should) be able to set voltages as floating numbers.
Plus, even when I declare "yoko1volts" as integer, it stills doesn't work. All I get is zero, zero, and zero...on the power supply meter everytime I press the numeric slide.
This is the section of the C code that is problemic:
int CVICALLBACK yoko7651dcvolts (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
double yoko1volts;
switch (event)
case EVENT_COMMIT:
GetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651DCVOLTS, &yoko1volts); // to read the values entered on the numerical meter on the user interface
yk7651_set_volts (yoko76511Panel, yoko1volts); // set the entered values as voltage on the instrument
break;
return 0;
This is the related h-file:
#define YOKO7651_1 4
#define YOKO7651_1_YOKO7651SWITCH 2 /* control type: binary, callback function: yoko7651switch */
#define YOKO7651_1_YOKO7651DCVOLTS 3 /* control type: scale, callback function: yoko7651dcvolts */
Please help, how can I fix this issue?
All the drivers (including the YOKOGAWA 7651 power supply) are properly installed and mounted. As a matter of fact, I can successfully turn the power supply on and off with the code below:
int CVICALLBACK yoko7651switch (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
int yoko7651switchstate;
switch (event)
case EVENT_COMMIT:
GetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651SWITCH, &yoko7651switchstate);
SetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651SWITCH, !yoko7651switchstate);
yk7651_output (yoko76511Panel, !yoko7651switchstate);
break;
return 0;
It's just setting the voltage on the power supply that is very problematic. Any help is appreciated...Thanks.
Solved!
Go to Solution.

I second Al opinion of a disconnection between the UIR and the variable that holds the panel handle.
As a side note, I noted that the problematic line is reading the value of the controll whose callback is executed:
#define YOKO7651_1_YOKO7651DCVOLTS 3 /* control type: scale, callback function: yoko7651dcvolts */
int CVICALLBACK yoko7651dcvolts (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
double yoko1volts;
switch (event)
case EVENT_COMMIT:
GetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651DCVOLTS, &yoko1volts); // to read the values entered on the numerical meter on the user interface
yk7651_set_volts (yoko76511Panel, yoko1volts); // set the entered values as voltage on the instrument
break;
return 0;
In a situation like this, I would try using GetCtrlVal (panel, control, &yoko1volts); instead, that should get rid of all problems in panel handle / control ID.
Despite this solution is working, in any case I would deep into the problem as an incorrect panel handle can lead to erratical behaviour in other places of the program.

Getting error when trying to login to CR XI server on suse linux server

http://www.experts-exchange.com/Database/Reporting_/Crystal_Reports/Q_21747694.html
Hello,
I'm getting the above error when I try to login as administrator (blank password).
This did work until I rebooted the linux server.
I checked there are no port conflicts (nothing is using port 6400).
I restarted the services manually, I even rebooted server and then restarted ccm services manually but no luck. I did find this is a known problem with linux crystal reports server but nothing stated about how to resolve it.
Finding solutions in the SAP portal is difficult! This is about as user friendly as the Cisco support website. Cisco portal is AWEFUL.
I'm in process of getting a support contract from SAP but it's taking a long time.
I have to state the support from SAP is a big step DOWN from the business objects support. We were able to call and speak to engineers in a few minutes.
With SAP support I was able to talk to some foreigner (asian or indian) to tell me that there is no phone support with SAP. This after being redirected at least 4 times between departments.
Wow! So what do the other business objects customers have to say about the SAP support?
I can't help but wonder about moving on to another solution for publishing reports.
A vendor who actually gives a damn about the customers.

this worked until I rebooted the server.
I'm getting error showing it's trying to connect to a mysql database 'BOE115'.
This server does have a mysql db running on it, but that db has no instance of BOE115.
It also shows it's trying to connect as a user that isn't on the database.
Where can I see the script with user/password that is trying to run and connect to the mysql db?
Also, why didn't the install create the instance and user?
Why did this work until I rebooted?
There is no firewall on this server, that has been disabled.
Thank you,
Oskar
