Hello,

We are using the 1.2.0.2 version of your Power Web ASP.NET Upload component. The infrastructure
is Windows 2008/IIS 7.0 64 bit. In the application pool we set up true the Enable 32 bit applications.

When we open the web page which uses this component and do something what not use the control (for example just post the data without upload) then we got NullReference Expection.

The exact message is:

NullReferenceException: Object reference not set to an instance of an object.]
  Dart.PowerWEB.FileUpload.FileUploadModule.context_BeginRequest(Object sender, EventArgs args) +687
  System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +68
  System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75


web.config part:

<system.webServer>

<validation validateIntegratedModeConfiguration="false"/>
<modules>
<add name="FileUploadModule" type="Dart.PowerWEB.FileUpload.FileUploadModule,Dart.PowerWEB.FileUpload" preCondition="managedHandler" />
<add name="CallbackManager" type="Dart.PowerWEB.FileUpload.CallbackManager,Dart.PowerWEB.FileUpload" preCondition="managedHandler" />
<remove name="ScriptModule" />
<add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</modules>

<handlers>

<remove name="ScriptHandlerFactory" />
<remove name="ScriptHandlerFactoryAppServices" />
<remove name="ScriptResource" />
<remove name="WebServiceHandlerFactory-Integrated" />
<add name="Dart.PowerWEB.FileUpload.GetResource.aspx_*" path="Dart.PowerWEB.FileUpload.GetResource.aspx" verb="*" type="Dart.PowerWEB.FileUpload.ResourceHttpHandler,Dart.PowerWEB.FileUpload" resourceType="Unspecified" preCondition="integratedMode,runtimeVersionv2.0" requireAccess="Script"/>

<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</handlers>

    <urlCompression doDynamicCompression="true" />
</system.webServer>

Let me know if we do something wrong, I read the forum but I didn't find any solution for us.

We use this code on Windows 2003 server without any problem.

Thanks,
