• Windows Forms Is it possible to simulate a property for databinding on an object using ITypedList

  Is it possible to simulate properties on an object and have the simulated property bound to a windows form control I have seen examples using ITypedList to do this. But all the samples simulate the property on a collection of business objects and never on the business object itself. When i tried to do this on an object by adding a new property to the PropertyDescriptorCollection being returned, i get an ArgumentException when setting the datasource saying "Cannot bind to the property or column Company on the DataSource. Parameter name: dataMember". I will be happy to provide the source code if required. Thank You, Vish ...Show All

  I have a dll file created from vc++ which contains something like this below. extern "C" __declspec ( dllexport ) Byte OpenDevice(Integer DriverType,Byte *DriverName,Integer *pVidPid,Byte ForceLoad,Byte *CodeFileName,Handle *pDevice); And Handle declared as typedef void * Handle; in c.

• Visual C# ExtractAssociatedIcon not working well for some extensions (ex: .XML)

  Hi, I am using the Icon.ExtractAssociatedIcon to retreive the icon associated with some file extensions. While the code works generally fine, it does not return the expected Icon for some extensions, say .XML for example. I have also tried the Interop route (using the WIN32 API SHGetFileInfo, etc...), and it does the same thing, which I find quite logical. I suppose this is an issue with Windows more than .NET. Has any one fixed this Thanks Hi, Here is a sample cause that's causing me problem (make sure you create two files named t.txt and t.xml in the current directory): Icon .ExtractAssociatedIcon( "t.txt" ).ToBitmap().Save( "txt.jpg" ); Icon .ExtractAssociatedIcon( "t.xml" ) ...Show All

• Smart Device Development RAPI fails on Smartphone but works on Pocket PC

  In spite of the RAPI Security configuration being set to "allowed" I am unable to execute a function with CeRapiInvoke on a Smartphone device. It works properly on the Pocket PC device. CeRapiInvoke returns S_OK on the Pocket PC device, but returns 0x80090006 Invalid Signature on the Smartphone device. GetLastError returns 2148073478. CeRapiInit returns S_OK on both devices.

• Visual Studio The filename selected is not recognized as legal

  I'm completely new to VSS and am having problems. I can add projects and solutions to the database I've created, but I can't seem to open them from another machine. If I go to File, Open Project and select SourceSafe (LAN) and browse and select my SLN file (or VBPROJ file for that matter) and try to open it I get this error: The filename selected is not recognized as legal. Please select another file or rename the selected file. Any help would be appreciated. Like I said, I'm very new to this. I don't think it's related to the file name - I have this problem on my PC, when attempting to open any solution or project from SourceSafe through the open project dialogue. The same projects work fine from ot ...Show All

• Visual Studio Work Item creation from a web front end

  We want to design and implement a web UI that will allow users to create/ insert work items from a front end. For this the users should not have TFS explorer installed on their machines.

• Visual Basic Problem: Eventing Among Multiple User Controls on a Form

  I must be missing something simple, because I would think this would happen all the time.  But I can't find any reference to a problem like mine. I have a VS 2005 VB Forms application. I have defined a user control that contains several controls, events and properties.  Based on properties set at run-time, the appearance of the control changes.  When I have a single user control on a form, the events of the user control work fine - the user control behaves nicely.  But when I have two controls on the form (and I need two), the first one that I fire an event from works, but the second one does not. That is, the events of the first control used fire, but the events of the second control used do not.  Whic ...Show All
