• Does CAS Support Application Level Impersonation?

  - by Rob Wilkerson

  I have a PHP application that is successfully authenticating against a CAS server. One of the features supported by the application is impersonation; a user with the appropriate privileges can impersonate another of the application. Generally, this isn't a problem because the app itself can keep track of who the user is impersonating and manage privileges (which are based on username). A new requirement has come up, though, that requires the original app to include, via an iframe, content from a second PHP app that is also CAS-enabled. Somehow, I need for the second app to know whether impersonation is happening in the first. I don't want to pass usernames around for security reasons, so I'm wondering whether I can offload the responsibility for handling impersonation to the CAS server which is shared by both apps. Thanks.

• An Actor "queue" ?

  - by synic

  In Java, to write a library that makes requests to a server, I usually implement some sort of dispatcher (not unlike the one found here in the Twitter4J library: http://github.com/yusuke/twitter4j/blob/master/twitter4j-core/src/main/java/twitter4j/internal/async/DispatcherImpl.java) to limit the number of connections, to perform asynchronous tasks, etc. The idea is that N number of threads are created. A "Task" is queued and all threads are notified, and one of the threads, when it's ready, will pop an item from the queue, do the work, and then return to a waiting state. If all the threads are busy working on a Task, then the Task is just queued, and the next available thread will take it. This keeps the max number of connections to N, and allows at most N Tasks to be operating at the same time. I'm wondering what kind of system I can create with Actors that will accomplish the same thing? Is there a way to have N number of Actors, and when a new message is ready, pass it off to an Actor to handle it - and if all Actors are busy, just queue the message?

• How to convert a .NET WebService-Method-Result (Soap) into its original datatype?

  - by Marc

  Hello everyone. I have two "identical" webservices (Soap) on two different servers. Don't ask why :-) WebService-1 decides if it handels the request itself or if it passes the request to WebService-2. If so, the response of WebService-2 should directly be returned from WebService-1. The response datatype is complex and self defined. With simple datatypes like 'int or 'string' there would be no problem. The response of WebService-2 is a serialized object (I think it is called "stubs") and theredore it is not possibel to pass this object through as the response of WebService-1 because the type of the objects doesn't match. Is there a simple way to convert the serialised datatype into its original type without buiding a complex converter?

• .NET Deployment of Interface/Classes for Command Pattern Question

  - by Jonno

  In theory I would like to produce 2 projects: 1) Asp.net (Sever A) 2) DAL running (Server B) I would like to utilise command objects to comunicate with the DAL. ASP.net instantiates a command class e.g. CmdGetAllUsers which impliments IMyCommand interface and sends it to the DAL (using ASMX or WCF). My question is: Would the class definition of CmdGetAllUsers need to exist on the DAL server? Or would having the interface definition be enough? My goal is to reduce the need to redeploy the DAL code, and have it as a fairly simple pass-through layer. Many thanks for your time.

• Jquery Delay Function Calls

  - by fizgig07

  I'm trying to find a way to delay all code that takes place after I make a service call. The reason for this delay is that my service returns code necesarry for the following functions and the result I pass is to these following functions is undefined. I have tried attaching the setTimeout() to the function that is called directly after the service call, but then it just skips the function I set the timeout on and jumps to the next function...My web method that I am calling is not that big and is not doing anything that is too intensive public bool GetSpreadsheetStatusForAdmin(string cacId) { SpreadSheetStatus result = new SpreadSheetStatus(); List<Data.Spreadsheet> spreadsheets = SpreadsheetManager.GetUserSpreadsheets(GetCurrent.Identity); if (spreadsheets.Count != 0) { foreach (Data.Spreadsheet spreadsheet in spreadsheets) { if (spreadsheet.Status == SpreadsheetStatus.Pending) { return true; } } } return false; } I had found the delay() and thought that might work, but I don't have jquery 1.4 and can't use it as of yet. is there anything that can help..?

• Python IPC, popen too slow

  - by UnableToLoad

  i need to run a subprocess (./myProgram) form python script and get output, actually i do this: import subprocess proc = subprocess.Popen('./generate_out', shell=False, stdout=subprocess.PIPE, ) while proc.poll() is None: out = proc.stdout.readline() data = doStuff(out) print(data) but is slow, sometimes pass a lot of time between the output produced by ./generate_out and the print(data), knowing that my doStuff() function is very fast, i think there is some buffer slowing down my pipe... Notes: ./generate_out, generates potentially an unlimited number of lines of finite length each. It seems that when too few chars are put in the pipe between the two processes nothing happens, then when enough is produced i get a huge print (non the expected behaviour!) sometimes i wait many seconds (10-20 and more) between generate_out print and python print) what can i do? maybe communicate() is faster? anithing else? Thank you a lot!

• Use Regular expression with fileinput

  - by chrissygormley

  Hello, I am trying to replace a variable stored in another file using regular expression. The code I have tried is: r = re.compile(r"self\.uid\s*=\s*('\w{12})'") for line in fileinput.input(['file.py'], inplace=True): print line.replace(r.match(line), sys.argv[1]), The format of the variable in the file is: self.uid = '027FC8EBC2D1' I am trying to pass in a parameter in this format and use regular expression to verify that the sys.argv[1] is correct format and to find the variable stored in this file and replace it with the new variable. Can anyone help. Thanks for the help.

• OpenAL device, buffer and context relationship

  - by Markus

  I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

• C# testing framework that works like JUnit in Eclipse?

  - by bluebomber357

  Hello all, I come from a Java/Eclipse background and I fear that I am spoiled by how easy it is to get JUnit and JMock running in Eclipse, and have that GUI with the bar and pass/fail information pop up. It just works with no hassle. I see a lot of great options for testing in C# with Visual Studio. NUnit looks really nice because it contains unit and mock testing all in one. The trouble is, I can't figure out how to get the IDE display my results. The NUnit documentation seems to show that it doesn't automatically show results through the VS IDE. I found http://testdriven.net/, which seems to trumpet that is makes VS display these stats and work with multiple frameworks, but it isn't open source. Is there anyway to get unit and mock testing working with the VS IDE like it does in Java with Eclipse?

• PHP: Do we have any command via which we can delete the contents of an file without opening it.

  - by Rachel

  Is there any way to remove the contents of an file in php, do we have any php command that does that, I know unlink but I do not want to delete the file instead I just want to remove the contents of that file. I have an file which I pass while called a getCurrentDBSnap function, it takes in the file from /home/test/incoming folder and populates currentDB table state into the file using fputcsv and puts back file to /home/test/outgoing. Currently file stays in incoming folder and when I can call the function getCurrentDBSnap it would take the file and override with latest state of DB into it. Q: My question is, is it possible instead of overwriting the file, we can remove the content of file after ever getCurrentDBSnap such that file in incoming folder would be always empty ? Hope it makes sense :)

  - by majdal

  Hi, I have the following arrays: int A[] = {0,1,1,1,1, 1,0,1,0,0, 0,1,1,1,1}; int B[] = {1,1,1,1,1, 1,0,1,0,1, 0,1,0,1,0}; int C[] = {0,1,1,1,0, 1,0,0,0,1, 1,0,0,0,1}; //etc... for all letters of the alphabet And a function that prints the letters on a 5x3 LED matrix: void printLetter(int letter[]) I have a string of letters: char word[] = "STACKOVERFLOW"; and I want to pass each character of the string to the printLetter function. I tried: int n = sizeof(word); for (int i = 0; i < n-1; i++) { printLetter(word[i]); } But I get the following error: invalid conversion from 'char' to 'int*' What should i be doing? Thanks!!

• How to access a structure member in a function that get it as void* type?

  - by Ahmad

  I want to have a function that accepts different type of structures as argument. So, since I don't have a specific type, I have to use void*. Now question is: when I pass a structure to this function, how can I access a known member of this structure inside the function? Specifically, I know that all structures have str1 as a member and I want, for example, print it. Here is a sample code: struct { char* str1; float tt1; } var1 = {"This is me", 12}; struct { char* str1; int tt2; } var2 = {"This is you", 18}; void printStruct(void* str) { printf("\n the structure string is %s", ??); //can I put something in ?? to print the string? } main(....) { printStruct(&var1); printStruct(&var2); }

• How to synchronize threads in python?

  - by Eric

  I have two threads in python (2.7). I start them at the beginning of my program. While they execute, my program reaches the end and exits, killing both of my threads before waiting for resolution. I'm trying to figure out how to wait for both threads to finish before exiting. def connect_cam(ip, execute_lock): try: conn = TelnetConnection.TelnetClient(ip) execute_lock.acquire() ExecuteUpdate(conn, ip) execute_lock.release() except ValueError: pass execute_lock = thread.allocate_lock() thread.start_new_thread(connect_cam, ( headset_ip, execute_lock ) ) thread.start_new_thread(connect_cam, ( handcam_ip, execute_lock ) ) In .NET I would use something like WaitAll() but I haven't found the equivalent in python. In my scenario, TelnetClient is a long operation which may result in a failure after a timeout.

• Forcing EditorFor to prefix input items on view with Class Name?

  - by Kohan

  I have an EditorFor: <%: Html.EditorFor(model => model.Client, "ClientTemplate", new { editing = false })%> This will bind coming down to the view fine (as expected) but will not bind bind back when the model gets posted. This is due to the form id's not being prefixed with "Client." Usually in this situation i just pass in model and then bind the inputs to model.Client.PropertyName in the Template but this is not an option in this case as the template is used on two different viewmodels (that have client on). Any suggestions on getting this to bind properly? Many thanks, Kohan.

• Understanding a skeleton of jQuery plugin

  - by TK

  At a website, I found the following code to make a jQuery plugin: (function($){ // Our code here... })(jQuery); I don't understand how the code above works. What I understand is that the code executes immediately because the very last () in function(){}(). So the entire code says that is an anonymous function that is run immediately. But I don't understand why the wrapping needs to pass jQuery and that inside it needs $ to be passed. From my understanding, $ is an alias to jQuery, meaning practically the same. What is the meaning of $ and jQuery here? How does the overall code work as a jQuery plugin?

• I have a question about URI templates in WCF Services

  - by Debby

  I have a web service with following operation contract and my service is hosted at http://localhost:9002/Service.svc/ [OperationContract] [WebGet(UriTemplate = "/Files/{Filepath}")] Stream DownloadFile(string Filepath); This web service would let users download file, if the proper filepath is provided (assuming, I somehow find out that proper filepath). Now, I can access this service from a browser by typing, http://localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but I want to send the location of the file. Lets us say users want to download file C:\Test.mp3 on the server. But how can I pass C:\Test.mp3 as {Filepath}? I get an error when I type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to web services and find that this community is the quickest way to get answers to my questions.

• Problem with passing parameters to SQL procedure using VBA

  Hi, I am trying to pass @intDocumentNo and @intCustomerNo to a stored procedure using VBA but only @intCustomerNo is updated in dbo.tblOrderHead. I don't think the problem is with the procedure because if I enter the values manually it runs properly. What am I doing wrong? VBA Code: Private Sub intCustomerNo_Click() Dim cmdCommand As New ADODB.Command With cmdCommand .ActiveConnection = CurrentProject.Connection .CommandType = adCmdStoredProc .CommandText = "uspSelectCustomer" '@intDocumentNo .Parameters("@intDocumentNo").Value = Forms![frmSalesOrder].[IntOrderNo] '@intCustomerNo .Parameters("@intCustomerNo").Value = Me![intCustomerNo] .Execute End With DoCmd.Close Forms![frmSalesOrder].Requery End Sub Procedure: UPDATE dbo.tblOrderHead SET dbo.tblOrderHead.intCustomerNo = @intCustomerNo , dbo.tblOrderHead.intPaymentCode = dbo.tblCustomer.intPaymentCode, dbo.tblOrderHead.txtDeliveryCode = dbo.tblCustomer.txtDeliveryCode, dbo.tblOrderHead.txtRegionCode = dbo.tblCustomer.txtRegionCode, dbo.tblOrderHead.txtCurrencyCode = dbo.tblCustomer.txtCurrencyCode, dbo.tblOrderHead.txtLanguageCode = dbo.tblCustomer.txtLanguageCode FROM dbo.tblOrderHead INNER JOIN dbo.tblCustomer ON dbo.tblOrderHead.intCustomerNo = dbo.tblCustomer.intCustomerNo AND dbo.tblOrderHead.intOrderNo = @intDocumentNo

• Inline assembler get address of pointer Visual Studio

I have tried void f(*p) { __asm mov eax, p // try one FAIL __asm mov eax, [p] // try two FAIL __asm mov eax, &p // try three FAIL } Both 1 and 2 are converted to the same code and load the value pointed to. I just want the address. Oddly, option 1 works just fine with integers. void f() { int i = 5; __asm mov eax, i // SUCCESS? }

• WPF integrate Windows live authentication for Microsoft health vault

  - by AnD

  Hi all, I'm just wondering if there's any way for WPF application integrated with windows live ID? and it's actually for windows health vault [www.healthvault.com] so health vault is using windows live id or open id to login into their system. and what i gonna do is, creating wpf application (instead of web application) for health vault, so all of the login form username pass and everything is handled inside the wpf application without showing/using any internet browser. so since this's quite new for me, i hope if there's somebody ever did this before especially for health vault system that run on standalone wpf app. alright, so that's it, thank you in advance!
