• .NET Development Strange: Session cleared after Directory.Delete

  Hi, usually session state is cleared after runtime errors (on a Win2003 Server with .NET2 using C#). But in my case a directory is deleted including all subdirectories and files using Directory.Delete(AbsolutePath, true), don't get any exceptions but nevertheless the session is cleared. By the way: Meanwhile aren't any session operations processed. Could anyone give me a hint, please Or did anyone experienced similar problems Thank you very much in advance! Marcus Hi Marcus. To solve your problem, try creating the directory outside of the application folder. If asp.net detects any changes to the application folder, f. e. from virus scanning or anything else - the application will be recompi ...Show All

• Smart Device Development Assembly reference

  I have the statement "using Microsoft.WindowsCE.Forms;" to take care of the fact that I am calling MessageWindow. I get the error message "The type or namespace name 'WindowsCE' does not exist in the namespace 'Microsoft' (are you missing an assembly reference ) ". I cannot find the assembly reference to add. What do I do now I am using .NET version 2.0. I am not sure why you are still getting the compile error after removing one of the using statements from WaveIn.cs, but in any case you can disambiguate by qualifying the Message class you want, i.e. instead of Message message; use Microsoft.WindowsCE.Forms. Message message; As an aside, I downloaded the library you referred ...Show All

• Visual Studio 2008 (Pre-release) dynamically getting list of forms from project

  hi all, i have multiple projects, one of them has several windows forms (wpf)... i want to get a list of these forms and be able to open them (or if i cant get that list dynamically, at least be able to open them) from another project.. i can open a form from another project by adding its reference but i dont know the right way to do it when there are multiple forms in one project... thanks in advance :) Hello Hawash, You would also use the System.Reflection namespace to get a list of the forms. Here is the code to do such: string assemblyName = ""; // You can enter .exe or .dll names. This .dll or .exe is the one that contains the types your are attempting to query Assembly assembly = ...Show All

• SQL Server Remove SP1 or install SP2 Dec. CTP

  This sounds trivial but it has become an issue here. We had the original RTM of SQL2005 with Reporting Services installed and running fine. We were explicity NOT installing SP1 because of a feature that was removed from reporting services (the select-all checkbox in the multi-value parameter). This feature is supposed to be back in SP2. So wouldn't you know it, somehow someone inadvertently installed SP1 in the course of doing windows updates and now users are complaining about the missing select-all checkbox. I figure my options are to either install the SP2 Dec CTP or try uninstalling SP1 (if that's even possible). Any recommendations Problem solved - I installed the hotfixes and now the select-all che ...Show All

• Visual C++ Exception handling showing undefined behaviour. Help !!!

  Question #1 : The following code crashes in Visual C++ compiler. It fails in the expression _BLOCK_TYPE_IS_VALID(). It means that, it is deleting a bad pointer. When I give a copy constructor, it works fine but the control does not even go in the copy constructor. Why is it showing this behaviour Question #2 : If I throw a local primitive type like an int, the address of that variable matches in the catch block if I am catching by reference. But for objects, the address for the variable in the catch block changes.

• .NET Development Trouble Adding Web Service through Data Source Config Wizard

  I am trying to write a web service in ASP.net and consume it in a windows forms application. This is what I am following: http://msdn.microsoft.com/vstudio/tour/vs2005_guided_tour/VS2005pro/Smart_Client/DisplayWebServiceData.htm In my windows app when I use the Data Source Configuration Wizard it will add a web reference but will not add my web service or its methods to the data sources explorer.

• Visual Studio 2008 (Pre-release) Updating a self-hosted service

  Context I'm designing a windows service to run a self-hosted scenario of services that are loaded from GAC. I've created a "drop" folder, in which to drop the .dll of the service I want to host. My service watches this folder and when a file has been dropped in, I install it into the GAC and load the ServiceHost. Now, my trouble is that when I'm "updating" an existing hosted service, it does not reflect the updated code that I've installed to the GAC, even though I close the ServiceHost and create a new service host from the GAC. It seems to cache to original service somewhere until I actually restart my Windows service. Question Is there a way to dynamically change the hosted service without ...Show All
