• Software Development for Windows Vista How to get a shared Data context inside a workflow instance accessable from all child activities?

  Hi, The idea is to have a data context accessable to all activity instances living inside a running workflow instance. This data context class instance is prepared before the workflow is started and should be retrieved back ( to the caller) when the workflow has completed or terminated ( to gain informations about state/error conditions). 1. Is there a build-in way to do so It seems like ActivityExecutionContext which is given for each execute does not solve this issue. Here's my happy guess solution to solve this issue. I've created a custom SequentialWorkflowActivity which will serve as base class for all my workflow definitions called SequentialWorkflowActivityBase . public partial class SequentialWorkflowActivityBase : Sequ ...Show All

• Visual Studio Express Editions Install C# and C++?

  Hi, Newbie here to C/C++ but I have done some VB in the past. I installed the Visual C++ Express edition about a week ago without a problem and have had some time to play about with it and found it to be great. So I thought I'd try Visual C# Express and see what the difference was between the 2 languages. The download and install went perfectly, without a hitch until I tried to start a new project. I went File:New and selected a template (doesn't matter which, same problem for all) clicked OK and got an error box pop up with the message ' The filename, directory name, or volume label syntax is incorrect. (Exception from HRESULT:0x8007007B) ' I uninstalled both C++ Express and C# Express and then reinstalled them both and I stil ...Show All

• SQL Server SSIS on cluster: Access is denied?

  Background info: I have two physicals machines PhysicalS01 and PhysicalS02, clustered together as Cluster01.

• Software Development for Windows Vista How to deal with app data shared by many users?

  In the Vista documentation it is said that application data which is used by several different users is supposed to be placed in C:\ProgramData\<appname>. However, when a user has created for example a file in this directory, the file belongs to this user and can't be written to by other users even though it's placed in a supposedly common directory. How can I make this file available to all users Does anyone have a detailed explanation to the above mentioned issue. In my point of view it would mean that you have to change the acl for every file which is intendent to be changed by several different users. Kind regards, Lela ...Show All

• Software Development for Windows Vista Picture taken date missing

  Hello Windows Vista 32bit Ultimate (German): Sometimes the EXIF-data "date picture taken" (in German "Aufnahmedatum") is empty in Windows Explorer. Escpecially if I edit the JPG-Image with PaintShopPro 11 and save it, the date will be empty in explorer view, but still exists in EXIF-Tags. If I transfer this Picture to another PC with Windows XP, the "date picture taken" still exists. Also if I open the picture with other Programms, the date is ok. Just in explorer its empty. Maybe in Windows Vista Explorer there is shown a wrong EXIF-Tag Best regards I too have a new Dell Inspiron 1520 laptop running Vista Home Edition. Copied photos from Windows98 ...Show All

• Visual C# exposing a C# DLL's members to non .NET apps

  Hi, I posted this in another forum (slightly different question though) and the answers I recieved weren't very helpful. Basically, I need to create a C# DLL who's members can be accessed by a non .NET application (it's a Windows program called Extend). Now I was able to write one in C++ and have it's members be exposed using extern "C" int __declspec(dllexport), but so far have been unsuccessful in doing so in C#. Is it even possible Hi pappascd: Although very restrictive, I have succeeded in years past in exposing a subset of native methods from a VC++ class with __declspec(dllexport) without exporting all the members of a class.  This is the poor man's way of exposing an interfac ...Show All
