We have a program used httpwebrequest to download and cache, it works on windows, but when running the program in WRE (windows recovery environment), the download performs well, but there's never cache in INetCache folder. I know, the httpwebrequest http-cache control is provided by Wininet. I wrote a simple code to download and cache via Wininet API, which execute as expected on windows. But the CreateUrlCacheEntry failed in WRE(windows recovery environment) with errorcode 12004(ERROR_INTERNET_INTERNAL_ERROR). I know there's should be quite a lot different between windows and WRE. Is there any way to enable http-cache feature in WRE via wininet? e.g., appending some DLL or registry items to WRE? hoping you could give us some guide, which great meaning for us.
I also try downloadurltocachefile, it returns Failed on WRE

I have made an exe program using vb.net but I want to make a webpage on which that exe is embedded.
Like the way this site has done.
You already have the source code for your VB.NET application, the path of least resistance is to factor out the desired functionality into a library DLL. Your web server presumably runs Windows and so will probably have ASP.NET capability. Just reference the DLL in your ASP.NET project and call into that instead.
My advice is don't make a rod for your own back by creating your own CGI binaries:
With a CGI application you'll have to generate all of the response headers and markup by yourself, you'll also have to parse any inbound headers, cookies etc yourself. It's a lot of work to replicate functionality already present in ASP.NET
Enabling CGI executables on your web server increases the risk of a security compromise, either through a mistake in your VB.NET executable, or because via some other vector an attacker has been able to upload a malicious executable and run that.
Mono 3.2 MVC4 WebAPI application is running in Debian x64 VPS server. Mono is compiled from source and 4.5 subtree is used.
Application requires Chrome or Safari browser.
After refreshing browser window several times server does not work properly. I tried all known free possibilites:
Apache + mod_mono
After pressing browser refresh button several times server randomly returns 500 error for some pages
and apache error log contains "failed to map path" exception.
I posted it in
https://stackoverflow.com/questions/20356779/how-to-fix-failed-to-map-path-errors-in-mono-mvc4-application
and in
Mono ASP.NET mailing list without any response.
There are number of mono applications in server, maybe mod_mono selects wrong thread or is there some bug in webapi mapping implementation in mono.
Nginx + mono-fastcgi-server4.exe
Holding down F5 key causes 200% CPU usage forever in mono-fastcgi-server4.exe
I posted it in
https://stackoverflow.com/questions/20512978/how-to-limit-mono-197-cpu-usage-in-mono-fastcgi-server
and in
Mono ASP.NET mailing list without any solution.
Is looks like there is bug in mono fastcgi server or it is not compatible with mono 3.2
Using xsp4.exe directly
It causes "server does not return data" in Chrome if browser window is refreshed several times.
I posted this in
https://code.google.com/p/chromium/issues/detail?id=329311
without response.
Maybe xsp4 does not implement http protocol properly.
Havent tried ServiceStack since it cannot used for closed source development which is required. Also application uses also images, css, js files and MVC views which needs also served.
How to create proper server for mono which returns correct data ?
When 500 errors happen, somewhere in the mono class libraries an exception was thrown, you can find out more by using tracing:
mono --trace=E:System.Exception YourApp.exe
This way it's very possible that you find out what is causing the load problems you're seeing in each case (to do this for mono-fastcgi, you would need to add the trace argument in the script that calls mono-fastcgi-server4.exe).
I have problem printing reports to PDF through bullzip from Navision Application Server (1) if user is not in Local Admin group (2). Only under both conditions.
In Nav code I'm doing the following: init bullzip automation object (set all parameters to suppress GUI), run report to print document to virtual bullzip printer, catch output file. Thats it. Straight as a rail.
I have two environments: Windows Server 2008 and Windows 7 (different versions of Nav, but this is changing nothing). On Windows 7 it just do nothing (but works if user is admin). On server I can see error in Event Log (translated to English)
Faulting application gui.exe, version 9.8.0.1599, time stamp 0x517126dc, faulting module USER32.dll, version 6.0.6002.18541, time stamp 0x4ec3e39f, exception code 0xc0000142, fault offset 0x0006f52f, the process ID 0x3bc, application start time 0x01ce562238369fa9.
Gui.exe is a part of bullzip.
If I run the same code from Nav Classic Client, or from the same NAS launched in command line, or under local administrator account, or if i put the NAS user in local admin group - it works just fine.
To solve this problem i need to find out one of two and how to fix it:
What is the difference between local admin and regular user that could cause application to crash in non-interactive mode (service) under regular user account.
What is the difference in running NAS as service and as command line that could cause application to crash when run as service.
What I've tried so far: extend non-interactive desktop heap, give user all local privileges that admin have in gpedit. Not works. Don't know direction for further digging.
Any alternative free pdf printers advices are welcome.
This question is still actual. Though I've managed to setup PDF printing with PDFCreator. The tough part was to let several different NAS to print simultaneously. And now the setup have a bottleneck - PDFCreator's printing queue. With bullzip automations it could be avoided.
We've had some cases where third party DLL's have crashed within NAV due to permission restrictions.
The only effective way we could narrow down the files that it was trying to access was through using Process Monitor to try narrow down what was causing permission issues.
We found a folder within System32 to do with the System's Network Profile that some DLLs use. On that note, NAS's and such should be run under a domain account.
I think re-installing the application will do that,
Just make sure you are uninstalling each bullzip and ghost script,
Now Ghost script is tricky thing, if you are installing 32 bit over 64 then you are having problem,
refer this download link download appropriate version, install it,
and then install bullzip, after downloading new version from here
this will do..
then also if any problem(if you are using application for automation, you require new com object..) refer Forum, that explains most of application interface problems..
where you need to use public class PdfSettings with namespace bioPdf.
I hope this will help ..
If you look at the Linux ecosystem (especially the Ubuntu and Alestic EC2 images) there is a common technique where the VMs are pre-configured to look at the EC2 user-data and use it as a boot script. The nice thing about this approach is that you can write a boot script that further provisions your machine, allowing you to avoid making a new image every time your software that runs on the machine changes.
I want to do the same thing for Windows, but given that I'm an Mac and Linux guy, I'm a bit lost on where to start. My requirements are:
This must run on Windows Server 2008
A bootstrap script needs to start when the machine boots up, read the user-data file by pulling down the contents http://169.254.169.254/1.0/user-data
The bootstap script then needs to run the contents of that file as if it were a script
The script embedded in the user-data needs to run in such a way that it has access to the desktop environment (ie: it can launch a browser, etc).
I'm not quite sure how services work in Windows or if I need to enable auto-login, so any advice here would be appreciated. The ultimate goal is to run a Java program that launches some custom software that in turn launches a web browser (IE, Firefox, etc) and is capable of taking screenshots.
The screenshot part is interesting, because in the past when I've tried this the only way I could get something other than a black screen was to have UltraVNC or RealVNC boot up as a service, though I don't know why that helped.
I'm looking for answers to three specific questions, as well as any general advice:
Should I be focussing on a Windows service or auto-login + bat file in the "Startup" folder?
If I use a Windows service, is there anything special that I need to do to make sure desktop access and/or screenshots are available?
Do you recommend any tools for common Linux commands, like curl or wget? Last time I used Windows I used Cygwin a lot, but is there something more appropriate to use here?
I have not tried auto-login on Windows instances in EC2, but here's the support document on how to enable it.
We boot-strap our Windows instances using a custom AMI with a custom Windows 'install' service already installed. The boot-strap installer reads a URL from user-data at startup. The URL points to a ZIP file stored in S3. The installer then downloads, un-zips, and executes the actual application installer -- in our case a simple CMD fie.
This setups allows us to have one base AMI and then be able to easily overlay 15+ different application configurations (without having to rebuild the AMI). If you only have one application configuration this may be overkill for your situation.
The only trouble we ran into was having our installer service start to early -- changing the service startup mode to "Automatic Delayed" fixed that issue.
We wrote our boot-strap installer in Java, launched via YAJSW, because we're comfortable with it. If you just want a few simple Unix tools, most are available pre-compiled for Windows, for example wget.
For something completely different, you could try PsExec to configure the instance after it has booted.
You can try using RightScale's free developer account to create plain Powershell scripts and associate them with your Windows instances to run at boot time. The RightScale dashboard solves exactly the problems you are trying to solve above.
DISCLAIMER: I work for RightScale.
As for screen capture CutyCapt is a simple tool you can point at a URL and generate an image from.
Unxutils is a great solution for those looking for unix tools on Windows. It's got the wget.exe that you're looking for, however, using Powershell to download stuff is not so bad either:
$wc = new-object system.net.webclient
$wc.DownloadFile("http://stackoverflow.com","test.html")
If you can write a batch file to do your setup, then you can run it at startup of the vm by doing this:
1. Run REGEDT32.EXE.
2. Modify the following value within HKEY_CURRENT_USER:
Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ParseAutoexec
1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed
As an answer to #3, I would say that you can do just about anything in a batch file that you need which includes downloading from a ftp server (but not from a http server). I am really interested in this stuff and so if you have questions, try asking me.
If you use Elastic Beanstalks you can use this:
Customizing the Software on EC2 Instances Running Windows
It uses YAML formatting standards, e.g.
packages:
msi:
mysql: http://dev.mysql.com/get/Downloads/Connector-Net/mysql-connector-net-6.6.5.msi/from/http://cdn.mysql.com/
or
sources:
"c:/myproject/myapp": http://s3.amazonaws.com/mybucket/myobject.zip
I know this is a little bit late to help out with the original post but for anyone who is still reading this one solution is to use the http://cloudinitnet.codeplex.com/ project. The service is easily installed using a powershell script and will create a local administrator account to use while running.
The goal for this project was to replace the Cloud-Init project used in Amazon Linux and Ubuntu.
I am running my C++ servi ce on Win2008 server machine. It crashes randomaly, and i do not know why. This is happening on multiple machines in customer site.
How can i configure the system to auto generate a dump of the process?
I need a method that will require minimal installations and UI, preferably only some registry hacks.
Thanks.
[edit] waiting...
You can use Windows Error Reporting locally on a machine without having to involve Microsoft and without having to sign your code. WER can be configured to store local copies of dumps. The MSDN documentation is here:
http://msdn.microsoft.com/en-us/library/bb787181(v=vs.85).aspx
It's a simple, well thought-out system, and is only a couple of registry settings to configure.
If your customer allows then i would suggest you to install DebugDiag from Microsoft. You can configure the tool to generate dumps when your application crashes and ask them to send you those dumps. I have used this quite often and found it to be successfull. If any help required please let me know.
Sign your executable then register with Microsoft for Windows Error Reporting (the signing certificate costs but WER is free). This will then collect the crash logs when the user hits the 'Send to Microsoft' button. These logs will then sit there until you log in to retrieve them. This requires no other installations on the user's machine.
