I have an ActiveX which seems to look for a file when starting. The problem is that the error doesn't give me any clue about which file it cannot access.
The msgbox is : The system cannot find the file specified
How can I know which file it wanted to access? Which tool can I use to know that?
Thanks
You can use Process Monitor from Sysinternals/Microsoft.

I'm interested in some information inside a shadow file (.shd) located inside the windows print spooling directory "C:\Windows\System32\spool\PRINTERS". Every time a print job is started, a spool file (.spl) and a shadow file (.shd) are created in that directory. So far I have been successful in detecting when a print job has started, and have been able to pause that print job. If you don't pause the job, the files eventually make their way to the printer and then are deleted by windows.
My problem is. I cannot open the .SHD files because they are locked in such a way that you can not read them while they are open by the sprint spooler. I've even tried going to the file in windows explorer and simply copying the file to another file, and that didn't work either. The .SPL spool files I can open though. I simply wait, and fairly quickly the spooler release that file. For the shadow file though, it permanently holds on to this file. Unfortunately, its the one I need.
The line of code I'm using specifically to open the file is as follows:
m_spoolJobStream = new FileStream(spoolFilePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
The IOException I get is:
The process cannot access the file 'C:\Windows\system32\spool\PRINTERS\FP00083.SHD' because it is being used by another process.
So yes, it is being used by another process. Its being used by the window's print spooler service. But I don't think there is anything I can do about that. All I want to do is read the file. I don't want to make any changes to it. Is there anything I can do here or am I just screwed?
Check the option: "Keep printed documents" (if you have HP printer) and then see your spool file folder, both shadow and spool files would be there.
Well, I did not find a way around this problem. I suspect there is no solution for this and it is by design. However I did find another way to get the information I wanted (at least it seems so thus far).
I'm using the FindNextPrinterChangeNotification() routine out of the winspool.drv library. This guy returns a pointer to a PRINTER_NOTIFY_INFO structure, which in turn contains an array of PRINTER_NOTIFY_INFO_DATA structures. Within that array, there is an element with its "Field" member marked as "JOB_NOTIFY_FIELD_DEVMODE". This element contains a fairly large structure of type DEVMODE. The structure is explained by M$ here http://msdn.microsoft.com/en-us/library/dd183565%28v=vs.85%29.aspx . This structure looks like it contains what I'm looking for and apparently is wrapped up in the .SHD file anyways according to this page http://www.undocprint.org/formats/winspool/shd. I'd like to know what else is in that .SHD file, but I still can't open it because its locked while the job is paused, and I suspect that it stays locked until the job is complete. Oh well, I think my new solution is more elegant anyways.
Just make sure you pause the job in the spool on BOTH your box and the server, then you should be able to copy/open/move the shd file just like you can the spl file. Worked for me, anyway...
This works for me:
- Hang your printer (e.g. jam the paper)
- Print and observe .SHD and .SPL being created
- Stop Print Spooler
- Open the file
The problem might be the FileShare.ReadWrite parameter. You're asking to read and write on the file and maybe that's why you get an error. You should try asking for read-only permission.
I am getting file list in my Java program using list() method of File class. When I run my program on Knoppix I get ???? instead of Cyrillic file names. It seems that problem is in knoppix, not java. I tried to use options for mounting file system, such as nls and iocharset, but it has no effect (or may be I use it in wrong way). Somebody can help me?
I think that problem is as you said with Knoppix. Probably you do not have Cyrillic font bundled, so there is no way to display these code points.
If you want to fix this, you will need fix distribution, as there is nothing wrong with the program. I am not sure if this is the question for https://serverfault.com/ or https://superuser.com/, but you can read their FAQ's and ask how to fix it there (probably you will need to re-create Knoppix distribution).
Are there any sources out there that show how to add an entry to the Mimetypes.rdf file that firefox uses. I want to associate a mime-type with my app that I have written in delphi and thought this would be the easiest way to do this.
Thanks,
Gail
No, the best way to do this is to register with the operating system and Firefox will pick that up.
Windows Live Messenger creates a number of files like
C:\Users\USERNAME\AppData\Local\Microsoft\Windows Live Contacts{ae86acef-5a45-4447-bc32-521fc9289e1a}\DBStore\contacts.edb
and stores contacts within. When looking on such files, it is obviouos that they have strict structure. However, I failed to find the description of contacts.edb structure in internet.
Does anybody knows this structure? Or maybe there are some parser sources available? (I do not need a exe for that, I know about NirSoft one).
There is a project called libesedb which might be of use here.
The contacts.edb file is an ESEBD file.
i have generated a help file for my project using sandcastle,a .chm file. but the content can only seen when i open it in my machine. i have gave that file to several friends none of them can see the content of the file. what is the wrong?? how can i resolve it?? any problem with my configurations??

The file is probably marked as "From the Internet" and therefore seen as possibly dangerous by the internet explorer trying to display the file.
Right-Click the file, and click the Unblock button on the General property page.
