• .NET Development Permission error when attempting to debug an web site on a server

  Hi... I have a web application written using VS2005, .net 2.0.. it's located on a server.. From my local Win XP machine I can map to the server just fine and edit/manipulate files and folders on the server with no problem. I can execute the application just fine from my local WinXP machine thru a browser.. I can also run Visual Studio on my local machine and edit/save files in the web application on the server from my local machine with no problem. However, when I attempt to run the application on the server in debug mode from my local machine I get a bunch of build errors reading: "Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934 ...Show All

• Windows Forms Monitoring Changes on a Tab Page

• Visual Basic Custom CType operator not being called

  This code defines a custom CType operator that converts Integer to TestNumber. This works great when converting from Integer to TestNumber. But an InvalidCastException occurs when converting from Object of type Integer to TestNumber. The online help for CType function implies that this call should work. "If the conversion is undefined, an InvalidCastException occurs. This can happen, for example, if expression is of type Object and its run-time type has no conversion to typename ." But because of the custom CType operator, there *is* a conversion from the run-time type (Integer) to typename (TestNumber). This problem is causing big headaches in my app. It happens on both VS 2005 and VS 2005 SP1. This seems like a CType bug ...Show All

• Visual Studio Team System Propagating Work Items across Team Projects

  Is there a way to propagate work items across different projects. For example, if a task is to be done for all team projects, must I create the same task on each team project Is there a way to export work items Is there a way to track these propagated work items without going to different projects You will have to create the work item in all projects. To make it easy, you can create it in 1 project and then create copies of it in all other projects, by right clicking on it and saying Create copy of work item. Or you can use Excel/Project to easily copy and paste the same work item into different team projects (one Excel/Project file per team project). Hope this helps! ...Show All

• Visual Studio Express Editions creating .exe program

  i have created a software in VB but when i publish it in my desktop to get the setup file its in application-manifest format and not exe how can i make the program a exe program ReneeC If this is the case, it is even more confusing! You test a program with the debugger, and then you certainly hope that the published program is the same or else you publish an untested version. I have newer used any other exe file than the one from the \bin\debug\ folder and this works fine - even for publishing. All this publishing stuff is really something, which need to be explained. I simply do not understand the wisdom behind. For example, how can more different solutions share the same source code (project), ...Show All

I have added a textbox at the bottom of the reports' layout and this only helps a little because only the firts page of the report shows clearly in mozilla.

• SQL Server How to pick up the last value within a time dimension member

  Hello, When creating a measure it is possible to select the Max or Min value of the input table column for a particular time dimension member. In a similar way, I need to be able to pick up the FIRST or LAST value for the particular time dimension member eg. Last value of the day, week, month etc. Does anyone know a way to do this I have experimented with Last NonEmpty but this seems to have some sum aggregate functionality which I do not want.
