  • View status of service running on remote machine

    - by tunwn
    The conditions are - I don't have administrator privilege - I want to see the status of a service in remote machine (server) I use the following code (vb.net with framework 2.0) to see the status Dim sqlSvc As ServiceController Svc = New ServiceController(My.Settings.serviceName, My.Settings.machineName) If sqlSvc.Status.ToString.Equals("Running") Then displayStatus("success", sqlSvc.Status.ToString) Else displayStatus("error", sqlSvc.Status.ToString) End If When running the code, InvalidOperationException is raised and found out that I need admin right in the server. Can I lookup the status of the service without having admin right in remote machine ?

  • Why doesn't VB.NET 9 have Automatic Properties like C# 3??

    - by Chris Pietschmann
    Would having a nice little feature that makes it quicker to write code like Automatic Properties fit very nicely with the mantra of VB.NET? Something like this would work perfect: Public Property FirstName() As String Get Set End Property UPDATE: VB.NET 10 (coming with Visual Studio 2010 and .NET 4.0) will have Automatic Properties. Here's a link that shows a little info about the feature: http://geekswithblogs.net/DarrenFieldhouse/archive/2008/12/01/new-features-in-vb.net-10-.net-4.0.aspx In VB.NET 10 Automatic Properties will be defines like this: Public Property CustomerID As Integer

  • Winform without .NET framework ?

    - by Karthick
    Hi, I have to create few forms and give it as direct EXE (instead of installer, which installs .NET framework, which the end user is not happy, they want something they can directly open and work). I know it can be done as web, but am looking for winforms? Please suggest which tool/technology can handle this? Thanks, Karthick

  • After passing a reference to an method, any mods using that reference are not visible outside the me

    - by Jason
    I am passing the reference of name to *mod_name*, I modify the referenced object from within the method but the change is not visible outside of the method, if I am referring to the same object from all locations how come the value is different depending on where I reference it? name = "Jason" puts name.object_id #19827274 def mod_name(name) puts name.object_id #19827274 name = "JasonB" end puts name.object_id #19827274 puts name #Jason String might be a bad example, but I get the same result even if I use a Fixnum.

  • Import CSV into Org-mode properties

    - by lecodesportif
    I would like to import a CSV into Org-mode. Others have already asked about importing CSV to Org-mode tables. That's not what I am trying to do. I need to import CSV to Org-mode properties. For example, a CSV like this: Name,Tel,Mobile,Fax John,11111,22222,33333 should become: :PROPERTIES: :Name: John :Tel: 11111 :Mobile: 22222 :Fax: 33333 :END: Do you happen to know a painless way to do it?

  • What to do when you need more verbs in REST

    - by Richard Levasseur
    There is another similar question to mine, but the discussion veered away from the problem I'm encounting. Say I have a system that deals with expense reports (ER). You can create and edit them, add attachments, and approve/reject them. An expense report might look like this: GET /er/1 => {"title": "Trip to NY", "totalcost": "400 USD", "comments": [ "john: Please add the total cost", "mike: done, can you approve it now?" ], "approvals": [ {"john": "Pending"}, {"finance-group": "Pending"}] } That looks fine, right? Thats what an expense report document looks like. If you want to update it, you can do this: POST /er/1 {"title": "Trip to NY 2010"} If you want to approve it, you can do this: POST /er/1/approval {"approved": true} But, what if you want to update the report and approve it at the same time? How do we do that? If you only wanted to approve, then doing a POST to something like /er/1/approval makes sense. We could put a flag in the URL, POST /er/1?approve=1, and send the data changes as the body, but that flag doesn't seem RESTful. We could put special field to be submitted, too, but that seems a bit hacky, too. If we did that, then why not send up data with attributes like set_title or add_to_cost? We could create a new resource for updating and approving, but (1) I can't think of how to name it without verbs, and (2) it doesn't seem right to name a resource based on what actions can be done to it (what happens if we add more actions?) We could have an X-Approve: True|False header, but headers seem like the wrong tool for the job. It'd also be difficult to get set headers without using javascript in a browser. We could use a custom media-type, application/approve+yes, but that seems no better than creating a new resource. We could create a temporary "batch operations" url, /er/1/batch/A. The client then sends multiple requests, perhaps POST /er/1/batch/A to update, then POST /er/1/batch/A/approval to approve, then POST /er/1/batch/A/status to end the batch. On the backend, the server queues up all the batch requests somewhere, then processes them in the same backend-transaction when it receives the "end batch processing" request. The downside with this is, obviously, that it introduces a lot of complexity. So, what is a good, general way to solve the problem of performing multiple actions in a single request? General because its easy to imagine additional actions that might be done in the same request: Suppress or send notifications (to email, chat, another system, whatever) Override some validation (maximum cost, names of dinner attendees) Trigger backend workflow that doesn't have a representation in the document.

  • Blackberry Player, custom data source

    - by Alex
    Hello I must create a custom media player within the application with support for mp3 and wav files. I read in the documentation i cant seek or get the media file duration without a custom datasoruce. I checked the demo in the JDE 4.6 but i have still problems... I cant get the duration, it return much more then the expected so i`m sure i screwed up something while i modified the code to read the mp3 file locally from the filesystem. Somebody can help me what i did wrong ? (I can hear the mp3, so the player plays it correctly from start to end) I must support OSs = 4.6.

  • Is my understanding of "select distinct" correct?

    - by paxdiablo
    We recently discovered a performance problem with one of our systems and I think I have the fix but I'm not certain my understanding is correct. In simplest form, we have a table blah into which we accumulate various values based on a key field. The basic form is: recdate date rectime time system varchar(20) count integer accum1 integer accum2 integer There are a lot more accumulators than that but they're all of the same form. The primary key is made up of recdate, rectime and system. As values are collected to the table, the count for a given recdate/rectime/system is incremented and the values for that key are added to the accumulators. That means the averages can be obtained by using accumN / count. Now we also have a view over that table specified as follows: create view blah_v ( recdate, rectime, system, count, accum1, accum2 ) as select distinct recdate, rectime, system, count, value (case when count > 0 then accum1 / count end, 0), value (case when count > 0 then accum2 / count end, 0) from blah; In other words, the view gives us the average value of the accumulators rather than the sums. It also makes sure we don't get a divide-by-zero in those cases where the count is zero (these records do exist and we are not allowed to remove them so don't bother telling me they're rubbish - you're preaching to the choir). We've noticed that the time difference between doing: select distinct recdate from XX varies greatly depending on whether we use the table or the view. I'm talking about the difference being 1 second for the table and 27 seconds for the view (with 100K rows). We actually tracked it back to the select distinct. What seems to be happening is that the DBMS is actually loading all the rows in and sorting them so as to remove duplicates. That's fair enough, it's what we stupidly told it to do. But I'm pretty sure the fact that the view includes every component of the primary key means that it's impossible to have duplicates anyway. We've validated the problem since, if we create another view without the distinct, it performs at the same speed as the underlying table. I just wanted to confirm my understanding that a select distinct can not have duplicates if it includes all the primary key components. If that's so, then we can simply change the view appropriately.

  • Creating an empty Drawable in Android

    - by Kai
    Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?

  • Strategy for converting a VB6 app to .NET

    Would it be a good idea to start converting forms into .NET one at a time which you would then invoke from the VB6 app via COM-interop. This way, by the end of the process you would just convert the 'shell' of the VB6 application into a new .NET app, and all your forms are ready to go in .NET. Is there a better strategy?

  • VBS Script Help.

    - by MalsiaPro
    I managed to get this code from you guys here, thanks so much with a collegue of mine, I ran this code a few times and it seems to work but stops after a while due to protected files such as system files, "Permission Denied" and then the script just stops, is there a way to modify the code below so that it can handle such protected files or whether it can pass them. Any advice or help is appreciated. Set objFS=CreateObject("Scripting.FileSystemObject") WScript.Echo Chr(34) & "Full Path" &_ Chr(34) & "," & Chr(34) & "File Size" &_ Chr(34) & "," & Chr(34) & "File Date modified" &_ Chr(34) & "," & Chr(34) & "File Date Created" &_ Chr(34) & "," & Chr(34) & "File Date Accessed" & Chr(34) Set objArgs = WScript.Arguments strFolder = objArgs(0) Set objFolder = objFS.GetFolder(strFolder) Go (objFolder) Sub Go(objDIR) If objDIR <> "\System Volume Information" Then For Each eFolder in objDIR.SubFolders Go eFolder Next End If For Each strFile In objDIR.Files WScript.Echo Chr(34) & strFile.Path & Chr(34) & "," &_ Chr(34) & strFile.Size & Chr(34) & "," &_ Chr(34) & strFile.DateLastModified & Chr(34) & "," &_ Chr(34) & strFile.DateCreated & Chr(34) & "," &_ Chr(34) & strFile.DateLastAccessed & Chr(34) Next End Sub Then call it from the command line like this. c:\test> cscript //nologo myscript.vbs "c:\" > "C:\test\Output.csv" Thank you :)
