I'm having to troubleshoot a website in IE7 (I currently have IE8 installed on my machine). I've installed Virtual PC and the IE7-on-XPSP3.exe file, but when I run the virtual machine, open IE7, and direct it to any page, it returns a blank screen. I know that there is some connection to the internet because it gets as far as grabbing the webpage's title and displaying it in the title-bar and tab, but then stops with a white page.
Has anyone come across this before, or can anyone suggest any solutions?
TIA,
Greg
EDIT: Actually it occasionally works, but occasionally IE crashes. I think the problem might have something to do with a message which pops up in the Virtual PC's taskbar: "Windows - Out of Virtual Memory. You system is low on virtual memory...'
FWIW the development on Virtual PC has been halted, I suggest you to use VirtualBox by Sun, which works great and without problems. What your specific problem is with regards to IE7 within a virtual machine, it is hard to troubleshoot. I don't really know what the IE7-on-XPSP3.exe file is (?? haven't seen it yet) but it must be something wrong with it obviously.
Found the solution - I just increased the virtual memory size following the instructions here: http://support.microsoft.com/kb/826513.
Thanks mare for your advice.

I upgraded from 10.3 (Rio) to 10.4 (Sydney) (with side-by-side installs), now having IDE docking exception, e.g.
Loading the desktop from "C:\Users\gary.walker\AppData\Roaming\Embarcadero\BDS\21.0\Default Layout.dst" for doc host windows "DockSite3" failed with message:
"EAccessViolation: Access violation at address 50165CBF in module 'rtl270.bpl'. Read of address 33DEEBFF"
Deleting all .dst files has resolved the issue in at least one case (a coworker).
Also, when attempting to debug a program, I was having a hard failure during debug startup that prevented debugger use, before application began execution. I resolved this problem by copying my Default desktop to my debug desktop.
Another friend had pretty much the same issue and was able to fix it, unfortunately he does not know how he fixed it.
Question is does anyone know how to fix this?
I am still waiting for an answer from Embarcadero and this is causing us real problems at the moment.
I received an answer from Embarcadero support.
It fixed the problem for me until I adjusted my desktops to the way I wanted them and them - still better than nothing. I suspect there is no solid work-around at this point in time. But, this may work well as long as you are not frequently changing your desktop layouts.
There were display layout changes introduced in 10.4.1 that cause the errors that you are seeing.
Shut the IDE down
In Windows Explorer navigate to: %AppData%\Embarcadero\BDS\21.0
Delete the *.dst files at that location (you can back them up first if desired)
In Windows Explorer navigate to the product's \bin directory. The default location is: 4. C:\Program Files (x86)\Embarcadero\Studio\21.0\bin
Copy the three default *.dst files from this location to the location in step 2
Start the IDE as normal
I'm having some trouble with WebExtensions in Firefox. I've got some code to track downloads, and it's working in Chrome, but not in FF.
I've boiled the code down to the minimal surface that works in Chrome but not FF:
function handleChanged(delta) {
console.log(delta);
}
chrome.downloads.onChanged.addListener(handleChanged);
Whether I use chrome.* or browser.*, the behavior remains the same: it doesn't work. I've tried executing this line:
console.log(chrome.downloads.onChanged.hasListener(handleChanged));
After adding the listener, and it does log a value of true. Oddly enough, adding an onCreated listener works just fine:
function handleCreated(delta) {
console.log(delta);
}
chrome.downloads.onCreated.addListener(handleCreated);
This yields the expected object dump in the console when a download is started. Unless I'm missing something extremely obvious, I'm inclined to think this is a bug. It is not mentioned to the incompatibilities list, and it is documented by Mozilla. The thing is, I don't see anybody else asking this question online, so I'm inclined to think a bug is unlikely and I'm messing something up.
If it helps, I'm running Firefox 51.0.1 (32-bit) on Windows 7 Enterprise x64 inside of VMWare Workstation on a Windows 7 Enterprise x64 host. I'm loading the extension using the "Load Temporary Add-on" button. It's not a problem with the core manifest or add-on itself, because three other types of listeners are working just fine. The script is running as a background script.
I appreciate any guidance. Thanks!
We have a higher-end Win7-64 Dell precision workstation notebook with an i7, 8 gigs of ram, tons of hd space and running dedicated AMD graphics. The machine is about a month old. It was one of the highest-end we could get at the time.
What we're experiencing is when we run our WPF/SQL Server (local) app, it tends to hang and stall, sometimes completely crashing, but mostly just hanging until we force it to close. However, the exact same installer running in a VMware virtual machine running on that same machine runs flawlessly. Actually, the VM install runs better than a lot of native installs on other machines. It's very snappy with no hangs or hesitations at all. But again, same app, same installer running direct in the OS, and we're back to the issues above.
We've ran all Windows updates.... we've tried completely reinstalling everything... .NET frameworks, SQL Server, video drivers, even updated the BIOS and checked for rogue services but it still happens.
At first we thought it was Symantec AV's real-time protection because when we first shut that off, things started getting snappy again (and slowed down and froze when it auto-re-enabled itself furthering this hypothesis) but then it just started slowing down again, and more surprising, that same AV is running in the VM without issue! Checked the exceptions but there weren't any.
We even tried forcing WPF to run in software-render mode but again, nothing.
Now the odd thing is this only seems to be happening on this and a few other machines, but we can't seem to find anything in common except they're all running Win7 64-bit. As such, we have absolutely no idea where to start. And since most are hangs, not crashes, we can't even look at the crash reports.
So can anyone give us any idea what else we can look at? This is holding up us shipping a three-years-in-the-making major release of our software so to say this is a show-stopper would be an understatement. We've been stumped for about a month now and getting nowhere fast.
Found it!! Turns out there's a bug in .NET 4.0 regarding UI Automation and the changes MS introduced. Here's the info, and the fix! (Note: Even if you call MS, they will send you a link, but it's always a broken link. I managed to track this down manually.)
Note: Their article talks about a specific case that causes this behavior, but if you google around, you'll see tons of issues around hangs related to those DLLs. The latest is they're promising a fix in the .NET 4.5 runtime (from a MS post on this issue.)
Here's the KB article...
http://support.microsoft.com/kb/2484841/en-us
...and here is the actual hotfix.
http://archive.msdn.microsoft.com/KB2484841/Release/ProjectReleases.aspx?ReleaseId=5583
Apparently the VM didn't suffer from this. We weren't sure if the VM had the hotfix applied or not or if this only happens on non-virtualized machines. Still, this solved all of the issues and the app is now snappy again. (Man, was this fun to track down! Ugh!!)
I've been working on this problem on and off for about a month. I don't expect anybody to be able to give me a definitive answer. I'm just completely out of ideas at this point and could use anything.
The problem is that my app crashes on only some models of phones. I have an HTC surround and it runs fine. It has also been tested on a Samsung Focus and it works there to. It crashes pretty consistently on a HTC mozart. There are other phones it crashes on but I don't know what models they are. I don't have access to an HTC mozart so debugging has been very difficult.
I'm handling the application UnhandledException event and I have try catch around every background thread. The error handling code never runs.
What I know:
Sometimes it freezes and requires a press of the power button. At least once it required the battery taken out. Most of the time it freezes and then crashes.
Most of the time it crashes on the main menu, before everything displays.
It's not 100% consistent. Sometimes it works for a little bit, but never very long.
It's not because it's out of memory. Most of the time it crashes while using less then 8MB.
When all the exception handling didn't work I added debug logging. This slows things way down but at the same time the issue goes away.
These symptoms make it sound like a deadlock to me. Although I have gone over the code and there is no thread ever entering more then 1 lock at a time.
Any ideas on how I should track this down would be appreciated.
Edit: This is a WP7 version of my game. I've just been able to confirm with a volunteer with an HTC mozart that the simplest conversion of the code meant for to run on the web will crash on the phone. That's code has no networking, isolated storage, or sound.
I also should have mentioned that this has passed certification and was in the marketplace for a few days until I took it down because it got bad reviews (because it was unplayable for some people)
If the devices are locking up, then my suspicions would be to look at the areas where you are closest to the driver level/hardware, which (looking at your game) are:
the display
the sound
It could also be just about due to processing/CPU activity - but generally "User level" code shouldn't be able to lock up your phone - that functionality is reserved for kernel software.
The only way of really testing this is to get hold of a device where this "reliably crashes" (e.g. a Mozart) and to go through the process of disabling bits of functionality one by one.
If this is a Silverlight app, then I'd expect Microsoft to want to help - I'd contact them via AppHub and via their local Evangelist team - they'll have the means and the motivation to assist you.
I'm happy to assist on testing on a developer-unlocked HTC Trophy if that helps!
The only thing I can think of that's unique to the Mozart is that it has an 8MP camera and all others have a 5MP camera.
Are you using a CameraCaptureTask and expecting the returned image to be a certain size?
Other than that, what does the app do? what services and device functionality are you using?
Do you have any network access running on a background thread?
I had roughly the same problem when developing my WP7 app. As far as I can tell it isn't as much model bound as it is device bound. In fact I had my app deployed to 15+ Trophy's (my company gave all their employees one of those) and it would repeatedly crash on some of them all having the same firmware. Some of the feedback I got through the reviews seems to indicate that it also happens in the wild.
In my case the crash occurs primarily (only?) when the app is launched. There does seem to be a strong correlation between internet connectivity and crashing in that I can 'recreate' the crash by putting my phone in flight mode, unplugging the network cable from my computer and then deploying the app. In that case too it immediately crashes and no event or break point is ever raised.
My gut feeling tell me it might have something to do with the map control as that does tend to respond funky to poor connectivity when the application is loading (like displaying an error message that the card cant be loaded while simultaneously displaying the map)
Does your app also use the Map Control (in combination with a Pivot control perhaps?)
Some of the devices have issues where you need set things to "content" instead of "embedded resource" in your project.
Although i've more heard about that issue related to app startup time, as on some devices (HD7?) the load of the app was taking enough time that the app was never allowed to start, the OS thought it was taking too long and killed it.
I have a Flash application that uses SharedObject to save and read some data locally. As it is said everywhere Flash saves the data from the shared object to disk when the application is closed. And indeed it does when I test it with the stand-alone Flash Player or all of these browsers: Firefox, Opera, Safari, Chrome, Flock... But it doesn't work when I use IE (I've tried IE6 and IE7).
Does anyone know anything about this issue? Why might it be happening... and how to get it to work?
Are you using MultipleIEs or standalone versions of the IE browsers? I've had issues with that as it seems they don't work properly when installed together.
The best way to be sure is testing your application on someone else's computer with only one version of IE installed.
EDIT: Check out the hints below:
It seems that if you install things in a special order evrything seems to work better.
Install/upgrade to IE8
Install standalone IE7
Install MultipleIEs (IE6 and below)
Also check the IE Collection (finalbuilds.edskes.net/iecollection.htm) tool instead of MultipleIEs for better results.
