  • How to use pointer from COM object on C#?

    - by Jaeh
    All. I'm trying to use my old dll file on .net project. So I converted this unmanaged COM object to managed one by using [tlbimp.exe] util from Windows SDK. However, one method returns a Object as a return value, but whenever I try to use it, my program generates an error. The weird thing is below: //Object[] item = s.GetObjects(); //this generates an type error Object item = s.GetObjects(); //this works okay System.WriteLine(items); //prints System.Object[] rather than System.Object. It seems like it returns a pointer which contains an object array. Isn't it ? Please anyone tell me how to handle this, and is there any documentation for this issue ?

  • Sudo-ing Apache for a particular vhost

    - by djechelon
    I want to manage several SVN repositories for a particular vhost in my system. I want those to be owned by a particular user in the system and not by wwwrun/www. The other websites hosted by Apache should be regularly executed by the unprivileged wwwrun/www user. I'm using worker. How can I tell Apache that every request for a specific vhost must be served impersonating a specific user like I would do in IIS? (This will also come useful when running FUDforum)

  • Ubuntu server boot degraded raid

    - by beacon_bonanza
    I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails.

  • Where is the root

    - by smwikipedia
    I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My question is: Where is this "big tree" located?

  • Using PowerShell class to invoke a "[namespace.class]::method" style command

    - by Marco
    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\\boo.txt").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

  • Help with Linq and Generics

    - by Jonathan
    Hi to all. I'm triying to make a function that add a 'where' clause to a query based in a property and a value. This is a very simplefied version of my function. Private Function simplified(ByVal query As IQueryable(Of T), ByVal PValue As Long, ByVal p As PropertyInfo) As ObjectQuery(Of T) query = query.Where(Function(c) DirectCast(p.GetValue(c, Nothing), Long) = PValue) Dim t = query.ToList 'this line is only for testing, and here is the error raise Return query End Function The error message is: LINQ to Entities does not recognize the method 'System.Object CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression. Looks like a can't use GetValue inside a linq query. Can I achieve this in other way? Post your answer in C#/VB. Chose the one that make you feel more confortable. Thanks

  • Where is a Web Development Career fueled by Passion? [closed]

    - by JMC Creative
    Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.

  • Why does casting to double using "String * 1" fail? Will CDbl(String) work on all systems?

    - by Jamie Bull
    I have an application which contains the line below to assign a parsed XML value to a variant array. V(2) = latNode.Text * 1 This works fine on my system (Windows 7, Excel 2010) but doesn't work on some other system or systems - and I've not been able to get a response from the user who reported the problem. I've switched out the offending line for: V(2) = CDbl(latNode.Text) This still works on my system, but then I had no problem in the first place. The question is on what systems does the first approach fail and why, and will the second method always work? I'm sure I've used the "Stying * 1" trick elsewhere before and would like to know how concerned I should be about tracking down other occurrences. Thanks.

  • External WiFi Adapter for Eee PC 1000?

    - by Peter M
    I have an original Eee PC 1000 running the stock Xandros. I have run into problems where the internal WiFi card does not seem to have enough sensitivity to connect to a lot of access points. Although the computer will report APs in the area, unless the signal strength is over 80% (as reported by the Wireless networks application) I cannot seem get a connection. So is there a recommended USB WiFi adapter that is known to work with the Eee PC/Xandros system or in general with a Debian based system?

  • Breaking change October: Status waiting when create custom audience with add user data file?

    - by THACH LN
    In my system, I create a custom audience - data file - mobile advertiser ids with 10k user. After I created it, I refreshed API link to get information about the audience which I've just created: https://graph.facebook.com/act_xxx/customaudiences?fields=id,account_id,name,lookalike_spec,retention_days,subtype,approximate_count,rule,delivery_status,operation_status,data_source,permission_for_actions&limit=500&access_token=xxx. (After breaking change in October 2014, status field not return. So I see operation_status) I see that: "operation_status": { "code": 410, "description": "No file has been uploaded for this audience, or the previous upload has failed due to system error. Please try uploading the file again." } But after about 10s, I refresh again, and operation_status change to: "operation_status": { "code": 200, "description": "Normal" } My quetions is: how to check this audience's status is waiting ( uploading file) , like when I create on facebook not my our system. Thanks for all anwser.

  • Software for Automatic Remote FTP Backup

    - by Baez
    I'm looking for software (free or paid) that could perform a weekly automatic backup to an outside server via FTP. I've looked around and all I seem to be finding is either garbage shareware or free tools that are no longer supported. The system will be backing up from a Windows 7 desktop system to a Linux CentOS 5 server. Can someone direct me to a stable, reliable piece of software? This is for business documents so reliability is key.

  • What notes should I be taking, if any, at the beginning of a project?

    - by Justin R.
    I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

  • ArrayBlockingQueue exceeds given capacity

    - by Wojciech Reszelewski
    I've written program solving bounded producer & consumer problem. While constructing ArrayBlockingQueue I defined capacity 100. I'm using methods take and put inside threads. And I've noticed that sometimes I see put 102 times with any take's between them. Why does it happen? Producer run method: public void run() { Object e = new Object(); while(true) { try { queue.put(e); } catch (InterruptedException w) { System.out.println("Oj, nie wyszlo, nie bij"); } System.out.println("Element added"); } } Consumer run method: public void run() { while(true) { try { queue.take(); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("Element removed"); } } Part of uniq -c on file with output: 102 Element removed 102 Element added 102 Element removed 102 Element added 102 Element removed 102 Element added 102 Element removed 102 Element added 102 Element removed 102 Element added 102 Element removed 102 Element added 2 Element removed 2 Element added 102 Element removed 102 Element added

  • How to get the computer name (hostname in a web aplication)?

    - by Filipe
    Hi, how can I get the client's computer name in a web application. The user in a network. Regards // Already tryed this option string IP = System.Web.HttpContext.Current.Request.UserHostAddress; string compName = DetermineCompName(IP); System.Net.IPHostEntry teste = System.Net.Dns.GetHostEntry(IP); ssresult = IP + " - " + teste.HostName; // TODO: Write implementation for action private static string DetermineCompName(string IP) { IPAddress myIP = IPAddress.Parse(IP); IPHostEntry GetIPHost = Dns.GetHostEntry(myIP); string[] compName = GetIPHost.HostName.ToString().Split('.'); return compName[0]; } All of that, gives me only the IP :/

  • Reverse engineering a custom data file

    - by kerchingo
    At my place of work we have a legacy document management system that for various reasons is now unsupported by the developers. I have been asked to look into extracting the documents contained in this system to eventually be imported into a new 3rd party system. From tracing and process monitoring I have determined that the document images (mainly tiff files) are stored in a number of 1.5GB files. These files seem to be read from a specific offset and then written to a tmp file that is then served via a web app to the client, and then deleted. I guess I am looking for suggestions as to how I can inspect these large files that contain the tiff images, and eventually extract and write them to individual files.

  • Tkinter after that survives clock rewinding.

    - by Oren
    I noticed that in my version of Tkinter, the after() call does not survive system clock rewinding. If the after(x, func) was called, and the system clock was rewinded, func will be called only after the clock returned to its time before the rewind + x milliseconds. I assume this is because Tkinter uses the system-clock instead of the "time.clock" (the amount of time that the program is running). I tested it only on windows, and maybe its because I have an old version of Tkinter. I want my App to work on computers that synchronize their clock from the network... Does anyone have a simple solution?

  • How do I play a video through .net in windows 7

    - by Mykroft
    I had setup an app to play a video using the library suggested here this worked great for me for a long time until my machine was upgraded. In windows 7 I get the following exception that I'd never seen under XP: `System.BadImageFormatException: is not a valid Win32 application. (Exception from HRESULT: 0x800700C1) at MainApp.Controls.MediaControl.StopVideo() at System.Windows.Forms.Form.WmClose(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)` I've installed the June 2010 DirectX SDK and I'm still getting this error. Is there a different library I should be using or some setting that needs to be changed?

  • Overloading Console.ReadLine possible? (or any static class method)

    - by comecme
    I'm trying to create an overload of the System.Console.ReadLine() method that will take a string argument. My intention basically is to be able to write string s = Console.ReadLine("Please enter a number: "); in stead of Console.Write("Please enter a number: "); string s = Console.ReadLine(); I don't think it is possible to overload Console.ReadLine itself, so I tried implementing an inherited class, like this: public static class MyConsole : System.Console { public static string ReadLine(string s) { Write(s); return ReadLine(); } } That doesn't work though, cause it is not possible to inherit from System.Console (because it is a static class which automatically makes is a sealed class). Does it make sense what I'm trying to do here? Or is it never a good idea to want to overload something from a static class?
