  • Excel pivot refresh, save and close in Access VBA code

    - by schneidm
    I am using the following code to refresh Excel pivot tables from an Access application. What is the best way to save and close the Excel app after the pivots refresh? In my last attempt the code was trying to save and close before the pivots had refreshed. Private Sub Command161_Click() Dim objXL As Object, x On Error Resume Next Set objXL = CreateObject("Excel.Application") With objXL.Application .Visible = True 'Open the Workbook .Workbooks.Open "myfilepath.xls" 'Refresh Pivots x = .ActiveWorkbook.RefreshAll End With Set objXL = Nothing End Sub

  • Id property not populated

    - by fingers
    I have an identity mapping like so: Id(x => x.GuidId).Column("GuidId") .GeneratedBy.GuidComb().UnsavedValue(Guid.Empty); When I retrieve an object from the database, the GuidId property of my object is Guid.Empty, not the actual Guid (the property in the class is of type System.Guid). However, all of the other properties in the object are populated just fine. The database field's data type (SQL Server 2005) is uniqueidentifier, and marked as RowGuid. The application that is connecting to the database is a VB.NET Web Site project (not a "Web Application" or "MVC Web Application" - just a regular "Web Site" project). I open the NHibernate session through a custom HttpModule. Here is the HttpModule: public class NHibernateModule : System.Web.IHttpModule { public static ISessionFactory SessionFactory; public static ISession Session; private static FluentConfiguration Configuration; static NHibernateModule() { if (Configuration == null) { string connectionString = cfg.ConfigurationManager.ConnectionStrings["myDatabase"].ConnectionString; Configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(cs => cs.Is(connectionString))) .ExposeConfiguration(c => c.Properties.Add("current_session_context_class", "web")) .Mappings(x => x.FluentMappings.AddFromAssemblyOf<LeadMap>().ExportTo("C:\\Mappings")); } SessionFactory = Configuration.BuildSessionFactory(); } public void Init(HttpApplication context) { context.BeginRequest += delegate { Session = SessionFactory.OpenSession(); CurrentSessionContext.Bind(Session); }; context.EndRequest += delegate { CurrentSessionContext.Unbind(SessionFactory); }; } public void Dispose() { Session.Dispose(); } } The strangest part of all, is that from my unit test project, the GuidId property is returned as I would expect. I even rigged it to go for the exact row in the exact database as the web site was hitting. The only differences I can think of between the two projects are The unit test project is in C# Something with the way the session is managed between the HttpModule and my unit tests The configuration for the unit tests is as follows: Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(cs => cs.Is(connectionString))) .Mappings(x => x.FluentMappings.AddFromAssemblyOf<LeadDetailMap>()); I am fresh out of ideas. Any help would be greatly appreciated. Thanks

  • function objects versus function pointers

    - by kumar_m_kiran
    Hi All, I have two questions related to function objects and function pointers, Question : 1 When I read the different uses sort algorithm of STL, I see that the third parameter can be a function objects, below is an example class State { public: //... int population() const; float aveTempF() const; //... }; struct PopLess : public std::binary_function<State,State,bool> { bool operator ()( const State &a, const State &b ) const { return popLess( a, b ); } }; sort( union, union+50, PopLess() ); Question : Now, How does the statement, sort(union, union+50,PopLess()) work? PopLess() must be resolved into something like PopLess tempObject.operator() which would be same as executing the operator () function on a temporary object. I see this as, passing the return value of overloaded operation i.e bool (as in my example) to sort algorithm. So then, How does sort function resolve the third parameter in this case? Question : 2 Question Do we derive any particular advantage of using function objects versus function pointer? If we use below function pointer will it derive any disavantage? inline bool popLess( const State &a, const State &b ) { return a.population() < b.population(); } std::sort( union, union+50, popLess ); // sort by population PS : Both the above references(including example) are from book "C++ Common Knowledge: Essential Intermediate Programming" by "Stephen C. Dewhurst". I was unable to decode the topic content, thus have posted for help. Thanks in advance for your help.

  • Win32_PageFileUsage WMI call returning 0 for CurrentUsage

    - by Ryan Duffield
    I am querying for the current page file usage on Windows-based systems. This is meant to run on the .NET Framework, version 2.0 SP1 and has been tested (and works!) on Windows Vista, Windows 7, Windows Server 2003 R2 and Windows Server 2008. On Windows Server 2003 SP2 (original release, not R2) it appears to return 0: using (var query = new ManagementObjectSearcher("SELECT CurrentUsage FROM Win32_PageFileUsage")) { foreach (ManagementBaseObject obj in query.Get()) { uint used = (uint)obj.GetPropertyValue("CurrentUsage"); return used; } } This is simply returning the results from the first row returned for the WMI call. Even when a page file is being used, it returns 0. What causes the result to be 0 when it should be returning a larger value? It may be something specific to the machine in question, and could have nothing to do with the operating system version. I've also tried this with and without elevated privileges with the same results.

  • Choosing a Java IDE for homework assignments

    - by Andrew
    Can anyone recommend a light Java IDE that doesn't require you to make new projects each time you want to compile and run a program? I just want to be able to open java files and compile and run them. I have already tried Eclipse and NetBeans but both require you to make a new project each time you want to compile and run a program. Making a new project is fine for large scale projects but for small school assignments this just makes the process more tedious. Thanks

  • Getting the date object to work in IE6 (w/ YYYY-MM-DD param)?

    - by J. LaRosee
    I just got IE6 sprung on me for a project that is going out into the wild soon, which means it's time to go back and comb through all of the CSS and JS. I've gotten hung up on the date object, however: $.validator.addMethod("dateRange", function() { var today = new Date(); var event_date_raw = $('#event_date').val(); var event_date_parts = event_date_raw.split("-"); var event_date = new Date( event_date_parts[2]+","+event_date_parts[1]+","+event_date_parts[0] ); if( event_date.getTime() >= today.getTime() ) return true; return false; }, "Please specify a correct date:"); event_date.getTime() is returning "NaN" in IE6 so the validation fails. The event_raw_date is in the YYYY-MM-DD format, which date doesn't seem to mind in every other browser... Thoughts?

  • Render an SSRS report with a Map as an image map without actually having a ReportViewer on the page

    - by Erica Merchant
    I have a report that has a Map with spatial data. Clicking an object on that map sends you to other pages on the site. I have tried a few different ways of displaying the report: If I put a ReportViewer on the actual page, the page sometimes takes 10+ seconds to load, but the report viewer creates a fully operable image map. If I create a ReportViewer in the code behind, I can use the Render method to to format the report as HTML4.0 and get the streamids from which I can extract the image (painfully). This is pretty fast (1-2 seconds), but only gives me an image, no image map. I can get a very similar functionality as the above example by using rendering extensions on the report URL to create an image and then set an image's source to this url. This is the fastest method, but still does not create an image map. So is there a way to create an image map from the report without having to use the ReportViewer? Or a way to substantially speed up the Report Viewer?

  • How can I create masking like this in AS3?

    - by Ólafur Waage
    I've worked a little bit with masks in AS3 but I'm not sure how I can do this with masks. I have two swf files that I have imported onto the Library as MC's with class names. One of the files is the start image and the other is the end image. The transition is a slide transition from the start image to the end image. You can think of the transition like in this example. But is it possible to do a slide transition like this using two swf's and "slide transitioning" between them?

  • Entering Complex Data into Access

    - by DataMakesMeCrazy
    Fairly new to Access and trying to do something that seems simple, but may be very complex. I want to create a database of projects, each project has several phases (ie proposal, marketing, etc) and that will allow for multiple employees to work on a single project. Ie Bob and John are working on project number 102. From here, i would like to enter the forecasted start and end dates for each phase of the project, and enter the forecasted number our hours each employee will be allowed to work on that phase of that project ie. Project - Employee - Phase - Start - End - (list weeks) 102 - Bob - Marketing - 12-May-10 - 21-May-10 - 3 - 5 (3 hours first week, 5 hours the second) and so on Basically would all this data be on one table, or several? And can access dynamically show the weeks between the start and end date so that i can input the hours? I feel this database will become severely complicated :S Thanks, J
