  • Defining DateDiff for a calculated column in a datatable

    - by Nir
    I have the column DateTimeExpired, and I would like to create another column called "Expired" which will show "Yes" or "No" according to the expiration date - "Yes" if the date has already passed. I wrote this: DataColumn colExpirationDate = new DataColumn("DateTimeExpired", typeof(DateTime)); DataColumn colExpired = new DataColumn("Expired", typeof(string), "IIF(DateDiff(DateTimeExpired, date())>= 0,'No','Yes')"); But I get an exception "The expression contains undefined function call DateDiff()." (please note that I always want to get the row, no matter if it's expired or not) How do I set the column's text to the correct form?

  • Acordex Image viewer throws out of memory exception in CITRIX environment

    - by neha
    We have a .net 2.0 application. In the .aspx page we are calling the java applet using . This applet is calling the Acordex Image viewer. In the production environment users are facing "out of memory" or "insufficient memory" issues when users try to open the image or magnify an image in Acordex viewer. Strangely when the users logout and login again they are able to see the same image without any errors. The website is hosted in a CITRIX environment. We have access to this environment but we are not able to reproduce this issue on the test servers or the local machines. We dont know what is causing this issue. What should we do to troubleshoot the issue? Do we have to increase the memory allotted to the users in CITRIX? The RAM is around 4 gb. Number of simultaneous users - 10-13. image size is max 2 mb Following is the code used to call Acordex image viewer:

  • MapView Annotation Callout action when opened

    - by Paul Peelen
    Hi, I have a mapview with serveral annotations. Every annotation has a leftCalloutAccessoryView which is a UIViewController class. The reason for this is that I want every annotation to load some data from the server, and add the result of that data to the annotation subTitle. This all works perfectly, except that I dont want to load all that data when my app is started, but I want to the remote call to be done only when the callout bubble is opened. Does anybody know how I can do this? The viewWillload, viewDidLoad ect. don't work in this case. Any examples as well? Best regards, Paul Peelen

  • Anobody succeeded in using ICEFaces with jQuery?

    - by hubertg
    Basically jquery is usable with IceFaces. Then only problem arises when partial updates of the page are used. For example you have a panelgroup where a jquery datepicker element (jquery UI datepicker plugin) is used. If the panelGroup is visible from the beginning it's no problem. The jquery call to jQuery(".datepicker").datepicker finds the input and jquery can do it's magic. But if the panelGroup is shown because of a partial update of the page (because the visible propery is changed) jquery is not called again. Does anybody has a solution to this problem? Basically the idea would be that jquery is run each time the dom has changed.

  • Membership.GetUser() within TransactionScope throws TransactionAbortedException

    - by Bob Kaufman
    The following code throws a TransactionAbortedException with message "The transaction has aborted": using ( MyDataContext context = new MyDataContext() ) { using ( TransactionScope transactionScope = new TransactionScope() ) { Guid accountID = new Guid( Request.QueryString[ "aid" ] ); Account account = ( from a in context.Accounts where a.UniqueID.Equals( accountID ) select a ).SingleOrDefault(); IQueryable < My_Data_Access_Layer.Login > loginList = from l in context.Logins where l.AccountID == account.AccountID select l; foreach ( My_Data_Access_Layer.Login login in loginList ) { MembershipUser membershipUser = Membership.GetUser( login.UniqueID ); } } } The error occurs at the call to Membership.GetUser(). My Connection String is: <add name="MyConnectionString" connectionString="Data Source=localhost\SQLEXPRESS;Initial Catalog=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient" /> Everything I've read tells me that TransactionScope should just get magically applied to the Membership calls. The user exists (I'd expect a null return otherwise.)

  • Can GhostScript run in Medium Trust

    - by SkippyFire
    I am using GhostScript to generate some thumbnails of PDF pages in an ASP.NET application. I have it wrapped in this library called GhostScriptSharp that just uses DllImport to call methods in the GhostScript DLL. It looks like this wont work on a medium trust hosting environment, either because of the fact that it is calling unmanaged code, or that it looks like the library is creating files all over the place (outside my virtual directory). I ran Process Monitor and saw it trying to Read, QueryNameInformationFile, CreateFile and QueryStandardInformationFile in places like: C:\WINDOWS\system32\Halftone\Default or C:\gs\gs8.63\lib\Halftone\Default or C:\gs\font\Halftone\Default Any ideas about whether this is "fixable" to run in medium trust? If I can't use GhostScript, is there another free/open source library that WILL work in Medium trust?

  • jQuery $.ajax success must be a callback function?

    - by b. e. hollenbeck
    I've created a wrapper function for jQuery's $.ajax() method so I can pass different dataTypes and post variables - like so: function doPost(dType, postData, uri){ $.ajax({ url: SITE_URL + uri, dataType: dType, data: postData, success: function(data){ return data; }); } The problem I'm having is getting the data (which is always JSON) back out. I've tried setting a var ret before the $.ajax() function call and setting it as ret = data in the success function. Am I being stupid about this? If I don't set a success function, will the $.ajax simply return the data? Or is it just success: return data? Or does success require a callback function to handle the data, which could just be return data?

  • How can I use Functions in VB.NET that's not in App_code

    - by megatoast
    I am currently working with an IPhone API which consist of about 40 pages of aspx along with their respective aspx.vb pages. They are all partial classes because the API continues to add other phone platforms to it. Currently I have them residing just in a folder. /API/0.1 and /API/1.0 ... How would I call the functions from those IPhone API classes without having to put them in the App_code? example: I have a partial class SetTextBroadcast with a function like this Function BroadcastMessage(ByVal Brodcast_recipient() As net.pmgateway.Recipient, ByVal str_Message As String) As net.pmgateway.Reply 'code here End Function How do i use that function in a webform? or do I need to put it in App_Code? something like this is what i'm looking for. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim objSetTextBroadCast as new SetTextBroadCast() End Sub but i get type "SetTextBroadCast" not defined. thanks for your help

  • Android: ContentObserver selfChange

    - by mattprecious
    Hi, In the ContentObserver class, the method onChange is passed a boolean selfChange that's defined as: "true if the update was caused by a call to commit on the cursor that is being observed." What's the proper way to update the cursor so that selfChange is set to true? My current code doesn't reference the cursor at all for an update and selfChange is always false as a result. ContentValues values = new ContentValues(); values.put("date", date.getTime()); getContentResolver().update(URI, values, "_id = " + id, null);

  • Rotating a full 360 degrees in WPF 3D

    - by sklitzz
    Hi, I have a ModelVisual3D of a cube and I want to animate it to rotate around its axis for 360 degrees. I make a RoationTransform3D which I tell to rotate 360 but it doesn't rotate at all, also if you say 270 degrees it rotates only 90 degrees but in the opposite direction. I guess he computer calculates the "shortest path" of the rotation. The best solution I have come up with is to make one animation turn 180 and after it finishes call another 180 to complete the full rotation. Is there a way to do it in one animation? RotateTransform3D rotateTransform = new RotateTransform3D(); myCube.Model.Transform = rotateTransform; AxisAngleRotation3D rotateAxis = new AxisAngleRotation3D(new Vector3D(0, 1, 0), 180/*or 360*/); Rotation3DAnimation rotateAnimation = new Rotation3DAnimation(rotateAxis, TimeSpan.FromSeconds(2)); rotateTransform.BeginAnimation(RotateTransform3D.RotationProperty, rotateAnimation);

  • Only run selenium test if previous selenium test fails

    - by Mike Grace
    I have several 'it' blocks in my selenium test file (using Ruby and rspec) that test various portions of my web application. Each 'it' block stops executing and goes to the next 'it' block if any of the conditions or code fails. Is there a way to run an 'it' block only if the previous fails or call a function to react to the failed test? Is there a better way to accomplish what I am wanting to do that doesn't involve an 'it' block? Example 'it' block it "should load example.com" do page.open("http://example.com") page.wait_for_page_to_load(25) end

  • Using Objective-C blocks with old compiler

    - by H2CO3
    I'm using the opensource iPhone toolchain on Linux for developing for jailbroken iPhones. I'd like to take advantage of the new (4.0, 5.0) iOS SDK features, but I can't as my old build of GCC doesn't understand the ^ block syntax. I noticed that blocks are just of type id (struct objc_object *). I know this from two resources: first, class-dump reports them as id, second, Apple docs clarify that "blocks can be retained". My quiestion is, how can I take advantage of blocks using this knowledge? I thought of something like: // this is in SDK 4.x/5.x - (void) doSomethingWithBlock:((int)(^block)(int)); // and I modify it like: - (void) doSomethingWithBlock(id)block; the question is: HOW TO ACTUALLY CALL IT? How do I create blocks? I can, of course, create function pointers (IMPs in particular), but how to achieve the object-like memory layout?

  • DCOM: CoCreateInstanceEx returns E_ACCESSDENIED

    - by MOE37x3
    I'm working on a DCOM application with the server and client on two machines, both of which are running WinXP with Service Pack 2. On both machines, I'm logged in with the same username and password. When the client on one machine calls CoCreateInstanceEx, asking the other machine to start up the server application, it returns E_ACCESSDENIED. I tried going into the server app's component properties in dcomcnfg and giving full permisions to everyone for everything, but that didn't help. What do I need to do to allow this call to succeed? Update: When the server app is running on a Windows 2000 box, I do not get this error; CoCreateInstanceEx returns S_OK.

  • Jython 2.5.1: "ImportError: No Module named os"

    - by Leonidas
    I looked through the other posts and bug reports and couldn't figure out what's causing this. I'm using Jython 2.5.1, in a Java project in Eclipse (Ubuntu 8.10). It has been added to the project as a standalone .jar file (I just replaced the old Jython 2.1 jar with this one). I'm running a script that uses the threading.py class. At some point the statement "import os" is evaluated from linecache.py and I get this error, which I can't seem to figure out how to fix: 'Execution failed.

  • How to digitally sign a message with M2Crypto using the keys within a DER format certificate

    - by Pablo Santos
    Hi everyone. I am working on a project to implement digital signatures of outgoing messages and decided to use M2Crypto for that. I have a certificate (in DER format) from which I extract the keys to sign the message. For some reason I keep getting an ugly segmentation fault error when I call the "sign_update" method. Given the previous examples I have read here, I am clearly missing something. Here is the example I am working on: from M2Crypto.X509 import * cert = load_cert( 'certificate.cer', format=0 ) Pub_key = cert.get_pubkey() Pub_key.reset_context(md='sha1') Pub_key.sign_init() Pub_key.sign_update( "This should be good." ) print Pub_key.sign_final() Thanks in advance for the help, Pablo

  • NSMutableDictionary is being treated as an NSDictionary

    - by Marc Gelfo
    Hi, I have a simple class with an NSMutableDictionary member variable. However, when I call setObject:forKey I get an error ('mutating method sent to immutable object'). The source of the problem is obvious from the debugger -- my NSMutableDictionary is actually of type NSDictionary. I must be missing something incredibly simple but can't seem to fix it. Here is the relevant code: // Model.h @interface Model : NSObject { NSMutableDictionary *piers; } @property (nonatomic,retain) NSMutableDictionary *piers; @end // Model.m @implementation Model @synthesize piers; -(id) init { if (self = [super init]) { self.piers = [[NSMutableDictionary alloc] initWithCapacity:2]; [self createModel]; } return self; } -(void) createModel { [piers setObject:@"happy" forKey:@"foobar"]; } @end If I put a breakpoint anywhere in the code and investigate self.piers, it is of type NSDictionary. What am I missing so that it is treated as an NSMutableDictionary instead? Thanks!

  • Windows 2008 RenderFarm Service: CreateProcessAsUser "Session 0 Isolation" and OpenGL

    - by holtavolt
    Hello, I have a legacy Windows server service and (spawned) application that works fine in XP-64 and W2K3, but fails on W2K8. I believe it is because of the new "Session 0 isolation " feature. (Note: As a StackOverflow newbie I'm being limited to one link in this post, so you'll need to scroll to bottom to lookup the links for '' items)* Consequently, I'm looking for code samples/security settings mojo that let you create a new process from a windows service for Windows 2008 Server such that I can restore (and possibly surpass) the previous behavior. I need a solution that: Creates the new process in a non-zero session to get around session-0 isolation restrictions (no access to graphics hardware from session 0) - the official MS line on this is: Because Session 0 is no longer a user session, services that are running in Session 0 do not have access to the video driver. This means that any attempt that a service makes to render graphics fails. Querying the display resolution and color depth in Session 0 reports the correct results for the system up to a maximum of 1920x1200 at 32 bits per pixel. The new process gets a windows station/desktop (e.g. winsta0/default) that can be used to create windows DCs. I've found a solution (that launches OK in an interactive session) for this here: *(Starting an Interactive Client Process in C++ - 2) The windows DC, when used as the basis for an *(OpenGL DescribePixelFormat enumeration - 3), is able to find and use the hardware-accelerated format (on a system appropriately equipped with OpenGL hardware.) Note that our current solution works OK on XP-64 and W2K3, except if a terminal services session is running (VNC works fine.) A solution that also allowed the process to work (i.e. run with OpenGL hardware acceleration even when a terminal services session is open) would be fanastic, although not required. I'm stuck at item #1 currently, and although there are some similar postings that discuss this (like *(this -4), and *(this - 5) - they are not suitable solutions, as there is no guarantee of a user session logged in already to "take" a session id from, nor am I running from a LocalSystem account (I'm running from a domain account for the service, for which I can adjust the privileges of, within reason, although I'd prefer to not have to escalate priorities to include SeTcbPrivileges.) For instance - here's a stub that I think should work, but always returns an error 1314 on the SetTokenInformation call (even though the AdjustTokenPrivileges returned no errors) I've used some alternate strategies involving "LogonUser" as well (instead of opening the existing process token), but I can't seem to swap out the session id. I'm also dubious about using the WTSActiveConsoleSessionId in all cases (for instance, if no interactive user is logged in) - although a quick test of the service running with no sessions logged in seemed to return a reasonable session value (1). I’ve removed error handling for ease of reading (still a bit messy - apologies) //Also tried using LogonUser(..) here OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE, &hToken) GetTokenInformation( hToken, TokenSessionId, &logonSessionId, sizeof(DWORD), &dwTokenLength ) DWORD consoleSessionId = WTSGetActiveConsoleSessionId(); /* Can't use this - requires very elevated privileges (LOCAL only, SeTcbPrivileges as well) if( !WTSQueryUserToken(consoleSessionId, &hToken)) ... */ DuplicateTokenEx(hToken, (TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE), NULL, SecurityIdentification, TokenPrimary, &hDupToken)) // Look up the LUID for the TCB Name privilege. LookupPrivilegeValue(NULL, SE_TCB_NAME, &tp.Privileges[0].Luid)) // Enable the TCB Name privilege in the token. tp.PrivilegeCount = 1; tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; if (!AdjustTokenPrivileges(hDupToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, 0)) { DisplayError("AdjustTokenPrivileges"); ... } if (GetLastError() == ERROR_NOT_ALL_ASSIGNED) { DEBUG( "Token does not have the necessary privilege.\n"); } else { DEBUG( "No error reported from AdjustTokenPrivileges!\n"); } // Never errors here DEBUG(LM_INFO, "Attempting setting of sessionId to: %d\n", consoleSessionId ); if (!SetTokenInformation(hDupToken, TokenSessionId, &consoleSessionId, sizeof(DWORD))) *** ALWAYS FAILS WITH 1314 HERE *** All the debug output looks fine up until the SetTokenInformation call - I see session 0 is my current process session, and in my case, it's trying to set session 1 (the result of the WTSGetActiveConsoleSessionId). (Note that I'm logged into the W2K8 box via VNC, not RDC) So - a the questions: Is this approach valid, or are all service-initiated processes restricted to session 0 intentionally? Is there a better approach (short of "Launch on logon" and auto-logon for the servers?) Is there something wrong with this code, or a different way to create a process token where I can swap out the session id to indicate I want to spawn the process in a new session? I did try using LogonUser instead of OpenProcessToken, but that didn't work either. (I don't care if all spawned processes share the same non-zero session or not at this point.) Any help much appreciated - thanks!

  • SWIG: Python list to uint32_t *?

    - by Lee Crabtree
    I'm trying to work with a Python module that was generated by SWIG. There's a C++ class defined that works like this (simplified): namespace Foo { class Thing { public: Thing(); ~Thing(); bool DoSomething(uint32_t x, uint32_t y, uint32_t z, uint32_t *buffer); }; }; When I try to call it from Python, I get an error about the last argument needing to be of type 'uint32_t*'. Normal Python integers work just fine for the other arguments, so I can't understand why a list of ints wouldn't work for the buffer. Any suggestions?

  • How do I guarantee cleanup code runs in Windows C++ (SIGINT, bad alloc, and closed window)

    - by Meekohi
    I have a Windows C++ console program, and if I don't call ReleaseDriver() at the end of my program, some pieces of hardware enter a bad state and can't be used again without rebooting. I'd like to make sure ReleaseDriver() gets runs even if the program exits abnormally, for example if I hit Ctrl+C or close the console window. I can use signal() to create a signal handler for SIGINT. This works fine, although as the program ends it pops up an annoying error "An unhandled Win32 exception occurred...". I don't know how to handle the case of the console window being closed, and (more importantly) I don't know how to handle exceptions caused by bad memory accesses etc. Thanks for any help!

  • Memory allocation in case of static variables

    - by eSKay
    I am always confused about static variables, and the way memory allocation happens for them. For example: int a = 1; const int b = 2; static const int c = 3; int foo(int &arg){ arg++; return arg; } How is the memory allocated for a,b and c? What is the difference (in terms of memory) if I call foo(a), foo(b) and foo(c)?

  • Why does TheyWorkForYou (TWFY) web API always returns '{}'

    - by Tartley
    I'm calling a web API exposed by TheyWorkForYou (TWFI). http://www.theyworkforyou.com/api/ I'm using the Python bindings provided by twfython: http://code.google.com/p/twfython/ I wrote some code to call this API a few months ago, at which time it worked fine. But now I dig it out to run it again, no matter what query I ask of the API, it always returns '{}' (an empty dictionary). For example the following code, which should return a list of all MPs: from twfy import TWFY API_KEY = 'XXXXXXXXXXXXXXXXXXXXXX' twfy = TWFY.TWFY(API_KEY) print twfy.api.getMPs(output='js') Am I being really dumb? What else should I check?

    I was following http://msdn.microsoft.com/en-us/magazine/ee336022.aspx but there were js errors. for example Sys is undefined So I added http://ajax.microsoft.com/ajax/act/40412/start.js. Then Sys.Data is undefined So I added http://ajax.microsoft.com/ajax/act/40412/MicrosoftAjaxDataContext.debug.js. But then TypeError: Sys.Data.OpenDataContext is not a constructor What shall I do to be able to call the service the way they do it on the first link? What are the scripts and resources needed? Thanks a lot.
