  • How to use a FolderBrowserDialog from a WPF application with MVVM

    - by David Work
    I'm trying to use the FolderBrowserDialog from my WPF application - nothing fancy. I don't much care that it has the Windows Forms look to it. I found a question with a suitable answer (How to use a FolderBrowserDialog from a WPF application), except I'm using MVVM. This was the answer I "implemented", except I can't get the window object and I'm just calling ShowDialog() without any parameters. The problem is this: var dlg = new FolderBrowserDialog(); System.Windows.Forms.DialogResult result = dlg.ShowDialog(this.GetIWin32Window()); In my ViewModel there the this has no GetIWin32Window() method for me to get the Window context. Any ideas on how to make this work?

  • Using WPF and SlimDx (DirectX 10/11)

    - by slurmomatic
    I am using SlimDX with WinForms for a while now, but want to make the switch to WPF now. However, I can't figure out how to get DX10/11 working with WPF. The February release of SlimDX provides a WPF example, which only works with DX 9 though. I found the following solution: http://jmorrill.hjtcentral.com/Home/tabid/428/EntryId/437/Direct3D-10-11-Direct2D-in-WPF.aspx but can't get it to work with SlimDX. My main problem is the shared resource handle as I don't know how to retrieve the shared handle from a SlimDX texture. I can't find any information to this topic. In C++ the code looks like this: HRESULT D3DImageEx::GetSharedHandle(IUnknown *pUnknown, HANDLE * pHandle) { HRESULT hr = S_OK; *pHandle = NULL; IDXGIResource* pSurface; if (FAILED(hr = pUnknown->QueryInterface(__uuidof(IDXGIResource), (void**)&pSurface))) return hr; hr = pSurface->GetSharedHandle(pHandle); pSurface->Release(); return hr; } Basically, what I want to do (because I think that this is the solution), is to share a texture between a Direct3d9DeviceEx (for rendering the WPF D3DImage) and a Direct3d10Device (a texture render target for my scene). Any pointers in the right direction are greatly appreciated.

  • How to get foreignSecurityPrincipal from group. using DirectorySearcher

    - by kain64b
    What I tested with 0 results: string queryForeignSecurityPrincipal = "(&(objectClass=foreignSecurityPrincipal)(memberof:1.2.840.113556.1.4.1941:={0})(uSNChanged>={1})(uSNChanged<={2}))"; sidsForeign = GetUsersSidsByQuery(groupName, string.Format(queryForeignSecurityPrincipal, groupPrincipal.DistinguishedName, 0, 0)); public IList<SecurityIdentifier> GetUsersSidsByQuery(string groupName, string query) { List<SecurityIdentifier> results = new List<SecurityIdentifier>(); try{ using (var context = new PrincipalContext(ContextType.Domain, DomainName, User, Password)) { using (var groupPrincipal = GroupPrincipal.FindByIdentity(context, IdentityType.SamAccountName, groupName)) { DirectoryEntry directoryEntry = (DirectoryEntry)groupPrincipal.GetUnderlyingObject(); do { directoryEntry = directoryEntry.Parent; } while (directoryEntry.SchemaClassName != "domainDNS"); DirectorySearcher searcher = new DirectorySearcher(directoryEntry){ SearchScope=System.DirectoryServices.SearchScope.Subtree, Filter=query, PageSize=10000, SizeLimit = 15000 }; searcher.PropertiesToLoad.Add("objectSid"); searcher.PropertiesToLoad.Add("distinguishedname"); using (SearchResultCollection result = searcher.FindAll()) { foreach (var obj in result) { if (obj != null) { var valueProp = ((SearchResult)obj).Properties["objectSid"]; foreach (var atributeValue in valueProp) { SecurityIdentifier value = (new SecurityIdentifier((byte[])atributeValue, 0)); results.Add(value); } } } } } } } catch (Exception e) { WriteSystemError(e); } return results; } I tested it on usual users with query: "(&(objectClass=user)(memberof:1.2.840.113556.1.4.1941:={0})(uSNChanged>={1})(uSNChanged<={2}))" and it is work, I test with objectClass=* ... nothing help... But If I call groupPrincipal.GetMembers,I get all foreing user account from group. BUT groupPrincipal.GetMembers HAS MEMORY LEAK. Any Idea how to fix my query????

  • Iterate over rows/checkboxes in a RadGrid

    - by ChessWhiz
    Hi, I have a Telerik RadGrid with a GridTemplateColumn that contains a checkbox, as follows: <telerik:GridTemplateColumn HeaderText="MINE" UniqueName="MyTemplateColumn"> <ItemTemplate> <asp:CheckBox id="MyCheckBox" runat="server"></asp:CheckBox> </ItemTemplate> </telerik:GridTemplateColumn> I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this: // read all values from database first, then... foreach(var chkbox in MyRadGrid.MasterTableView.Columns.FindByUniqueName("MyTemplateColumn").FindControl("MyCheckBox")) { chkbox.Checked = oneValue; } That doesn't work, because FindControl isn't a method of GridColumn, and it won't generate an iterable list of the checkboxes. What is the correct way to iterate through the checkboxes in the template column? Thanks!

  • Linq to Datarow, Select multiple columns as distinct?

    - by Beta033
    basically i'm trying to reproduce the following mssql query as LINQ SELECT DISTINCT [TABLENAME], [COLUMNNAME] FROM [DATATABLE] the closest i've got is Dim query = (From row As DataRow In ds.Tables("DATATABLE").Rows _ Select row("COLUMNNAME") ,row("TABLENAME").Distinct when i do the above i get the error Range variable name can be inferred only from a simple or qualified name with no arguments. i was sort of expecting it to return a collection that i could then iterate through and perform actions for each entry. maybe a datarow collection? As a complete LINQ newb, i'm not sure what i'm missing. i've tried variations on Select new with { row("COLUMNNAME") ,row("TABLENAME")} and get: Anonymous type member name can be inferred only from a simple or qualified name with no arguments. Also, does anyone know of any good books/resources to get fluent?

  • IEnumerable<CustomType> in PowerShell

    - by svick
    I'm trying to use Enumerable.ToList() in PowerShell. Apparently, to do that, I have to explicitly convert the object to IEnumerable<CustomType>, but I am unable to do that. It seems I can't correctly write IEnumerable<CustomType> in PowerShell. Both IEnumerable<string> and CustomType itself work correctly (the custom type I'm trying to use is called WpApiLib.Page), so I don't know what can I be doing wrong.

    Hi there! Objective: Serialize all the public properties of the ClassMain: public class ClassMain { ClassA classA = new ClassA(); public ClassMain() { classA.Prop1 = "Prop1"; classA.Prop2 = "Prop2"; } public string Prop1 { get; set; } public string Prop2 { get; set; } public ClassA ClassA { get { return classA; } } } ClassA: public class ClassA { public string Prop1 { get; set; } public string Prop2 { get; set; } } This is how i´m serializing: private void button1_Click(object sender, EventArgs e) { ClassMain classMain = new ClassMain(); classMain.Prop1 = "Prop1"; classMain.Prop2 = "Prop2"; XmlSerializer mySerializer = new XmlSerializer(typeof(ClassMain)); StreamWriter myWriter = new StreamWriter("xml1.xml"); mySerializer.Serialize(myWriter, classMain); myWriter.Close(); } In this case, the xml output is: <?xml version="1.0" encoding="utf-8"?> <ClassMain xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Prop1>Prop1</Prop1> <Prop2>Prop2</Prop2> </ClassMain> As you see, is lacking the ClassA properties. Can anyone help me out? Regards

  • WCF Error - Security processor was unable to find a security header in the message

    - by quinntheeskimo
    Hi, I'm getting what appears now to be a security error in my WCF Service. Originally my error was about a falted state(removed using around client proxy to clear this error), but have found more information through enabling trace. I have been unable to get my solution running after encountering this error, and even my backup copy now gets the same error. I'm not sure what has caused this to happen, I undone the changes I made (nothing relating to WCF) and still get the same error. The error from trace is - System.ServiceModel.Security.MessageSecurityException: Security processor was unable to find a security header in the message. This might be because the message is an unsecured fault or because there is a binding mismatch between the communicating parties. This can occur if the service is configured for security and the client is not using security. I'm not really sure what I need to do to fix this, any help would be usefull. The application was previously working.

  • There is no ViewData item of type 'IEnumerable<SelectListItem>' that has the key 'xxx'.

    - by Jimbo
    There are a couple of posts about this on Stack Overflow but none with an answer that seem to fix the problem in my current situation. I have a page with a table in it, each row has a number of text fields and a dropdown. All the dropdowns need to use the same SelectList data so I have set it up as follows: Controller ViewData["Submarkets"] = new SelectList(submarketRep.AllOrdered(), "id", "name"); View <%= Html.DropDownList("submarket_0", (SelectList)ViewData["Submarkets"], "(none)") %> I have used exactly this setup in many places, but for some reason in this particular view I get the error: There is no ViewData item of type 'IEnumerable' that has the key 'submarket_0'.

  • Microsoft Enterprise Library Caching Application Block not thread safe?!

    - by AlanR
    Good aftenoon, I created a super simple console app to test out the Enterprise Library Caching Application Block, and the behavior is blaffling. I'm hoping I screwed something that's easy to fix in the setup. Have each item expire after 5 seconds for testing purposes. Basic setup -- "every second pick a number between 0 and 2. if the cache doesn't already have it, put it in there -- otherwise just grab it from the cache. Do this inside a LOCK statement to ensure thread safety. APP.CONFIG: <configuration> <configSections> <section name="cachingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Caching.Configuration.CacheManagerSettings, Microsoft.Practices.EnterpriseLibrary.Caching, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </configSections> <cachingConfiguration defaultCacheManager="Cache Manager"> <cacheManagers> <add expirationPollFrequencyInSeconds="1" maximumElementsInCacheBeforeScavenging="1000" numberToRemoveWhenScavenging="10" backingStoreName="Null Storage" type="Microsoft.Practices.EnterpriseLibrary.Caching.CacheManager, Microsoft.Practices.EnterpriseLibrary.Caching, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Cache Manager" /> </cacheManagers> <backingStores> <add encryptionProviderName="" type="Microsoft.Practices.EnterpriseLibrary.Caching.BackingStoreImplementations.NullBackingStore, Microsoft.Practices.EnterpriseLibrary.Caching, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Null Storage" /> </backingStores> </cachingConfiguration> </configuration> C#: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Practices.EnterpriseLibrary.Common; using Microsoft.Practices.EnterpriseLibrary.Caching; using Microsoft.Practices.EnterpriseLibrary.Caching.Expirations; namespace ConsoleApplication1 { class Program { public static ICacheManager cache = CacheFactory.GetCacheManager("Cache Manager"); static void Main(string[] args) { while (true) { System.Threading.Thread.Sleep(1000); // sleep for one second. var key = new Random().Next(3).ToString(); string value; lock (cache) { if (!cache.Contains(key)) { cache.Add(key, key, CacheItemPriority.Normal, null, new SlidingTime(TimeSpan.FromSeconds(5))); } value = (string)cache.GetData(key); } Console.WriteLine("{0} --> '{1}'", key, value); //if (null == value) throw new Exception(); } } } } OUPUT -- How can I prevent the cache to returning nulls? 2 --> '2' 1 --> '1' 2 --> '2' 0 --> '0' 2 --> '2' 0 --> '0' 1 --> '' 0 --> '0' 1 --> '1' 2 --> '' 0 --> '0' 2 --> '2' 0 --> '0' 1 --> '' 2 --> '2' 1 --> '1' Press any key to continue . . .

  • Using telerik radGrid - how to set the Date format for autogenerated column in edit mode

    - by Mark Breen
    Hello All, Using VS2008, and Telerik radGrid version 2010.1.519.35 I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy. IOW, I need to change the culture of the form to en-GB culture. In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format. I am not sure whether I need to set this at web.config level, page level or at the column within the control. I am struggling with this for a month or more and any help would be appriciated, thanks Mark Breen Ireland BMW R80GS 1987

  • Passing multiple parameters in an MVC Ajax.ActionLink

    - by mwright
    I am using an Ajax.ActionLink to call an Action in a Controller, nothing special there. I want to pass two parameters to the Action. Is this possible using an Ajax.ActionLink? I thought that it would just be a matter of including multiple values in the AjaxOptions: <%= Ajax.ActionLink("Link Text", "ActionName", "ControllerName", new { firstParameter = firstValueToPass, secondParameter = secondValueToPass }, new AjaxOptions{ UpdateTargetId = "updateTargetId"} )%> Is it possible to pass multiple parameters? Where is a good place to learn more about the AjaxOptions?

  • WCF NetTcpBinding Buffered vs Streamed performance problems

    - by DxCK
    I wrote a WCF service that should transform any size of files, using the Streamed TransferMode in NetTcpBinding, and System.IO.Stream object. When running performance test, i found significant performance problem. Then I decided to test it with Buffered TransferMode and saw that performance is two times faster! Because my service should transfer big files, i just can't stay in Buffered TransferMode because of memory management overhead on big files at the server and client side together. Why is Streamed TransferMode slower than the Buffered TransferMode? What can i do to make Stremed performance better?

  • WinForms ReportViewer: slow initial rendering

    - by Bryan Roth
    UPDATE 2.4.2010 Yeah, this is an old question but I thought I would give an update. So, I'm working with the ReportViewer again and it's still rendering slowly on the initial load. The only difference is that the SQL database is on the reporting server. UPDATE 3.16.2009 I have done profiling and it's not the SQL that is making the ReportViewer render slowly on the first call. On the first call, the ReportViewer control locks up the UI thread and makes the program unresponsive. After about 5 seconds the ReportViewer will unlock the UI thread and display "Report is being generated" and then finally show the report. I know 5 seconds is not much but this shouldn't be happening. My coworker does the same thing in a program of his and the ReportViewer immediately displays the "Report is being generated" upon any request. The only difference is that the reporting server is on one server and the data is on another server. However, when I am developing the reports within SSRS, there is no delay. UPDATE I have noticed that only the first load of the ReportViewer takes a long time; each subsequent load of the same or different reports loads fast. I have a WinForms ReportViewer that I'm using in Remote processing mode that can take up to 30 seconds to render when the ReportViewer.RefreshReport() method is called. However, the report itself runs fast. This is the code to setup my ReportViewer: rvReport.ProcessingMode = ProcessingMode.Remote rvReport.ShowParameterPrompts = False rvReport.ServerReport.ReportServerUrl = New Uri(_reportServerURL) rvReport.ServerReport.ReportPath = _reportPath This is where the ReportViewer can take up to 30 seconds to render: rvReport.RefreshReport()

  • Visual Studio 2008 doesn't create *.refresh files for external DLL references... what am I missing?

    - by Cory Larson
    Hi all-- I've got a question about something that's just been irritating me. A colleague and I are building a support framework for our current client that we want to reference in other projects. The DLL we want as a reference in our project would be an external reference. We're adding it by doing "Add Reference...", then browsing to the location of the .dll. What I want Visual Studio to do is only add the .xml, .pdb, and a .dll.refresh file, but instead it copies the actual .dll (and .xml and .pdb) into the bin. When we rebuild the framework project, the other project that uses its .dll gets all out of whack until we drop and re-add the reference. Everything I've read online says that VS2008 is supposed to create the .dll.refresh files for you, but it never does. Any ideas? Am I missing something or doing something wrong? At this point I'm ready to add a pre-build event to simply copy the framework .dll into my bin, but the .refresh file seems like less of a hassle if it would just work. Thanks, Cory

  • OpenXML SDK: Make Excel recalculate formula

    - by chiccodoro
    I update some cells of an Excel spreadsheet through the Microsoft Office OpenXML SDK 2.0. Changing the values makes all cells containing formula that depend on the changed cells invalid. However, due to the cached values Excel does not recalculate the formular, even if the user clicks on "Calculate now". What is the best way to invalidate all dependent cells of the whole workbook through the SDK? So far, I've found the following code snippet at http://cdonner.com/introduction-to-microsofts-open-xml-format-sdk-20-with-a-focus-on-excel-documents.htm: public static void ClearAllValuesInSheet (SpreadsheetDocument spreadSheet, string sheetName) { WorksheetPart worksheetPart = GetWorksheetPartByName(spreadSheet, sheetName); foreach (Row row in worksheetPart.Worksheet. GetFirstChild().Elements()) { foreach (Cell cell in row.Elements()) { if (cell.CellFormula != null && cell.CellValue != null) { cell.CellValue.Remove(); } } } worksheetPart.Worksheet.Save(); } Besides the fact that this snippet does not compile for me, it has two limitations: It only invalidates a single sheet, although other sheets might contain dependent formula It does not take into account any dependencies. I am looking for a way that is efficient (in particular, only invalidates cells that depend on a certain cell's value), and takes all sheets into account. Update: In the meantime I have managed to make the code compile & run, and to remove the cached values on all sheets of the workbook. (See answers.) Still I am interested in better/alternative solutions, in particular how to only delete cached values of the cells that actually depend on the updated cell.
