• Architecture Thin client and smart client

  Continuing a thread I have posted somewhere around here (but could not find it), why do people usually say a smart client is able to work offline, and a thin client only works if connected to Internet. I consider this not true, since a thin client may be connected to a local Intranet. Then, it does not need to be in Internet, the connection will only need to be accessing the local BD inside the network, right Hi, The easiest way to think of a smart client is that it must always be available, even in a plane in the middle of the Pacific. For more information on thin versus smart clients consult the excellent Smart Client Architecture and Design Guide: http://www.microsoft.com/downloads/details.aspx familyid=8EC600BD-A2E5-44AC-9A ...Show All

• Visual Studio Team System Sharing workspaces and working folders between multiple domain users on the same machine

  At my company we do integration testing on a single dev box called DEVTESTING. We have a total of six domain users who log in to this machine (only one at a time, enforced through Terminal Services domain policies). All these users have access to only one workspace for TFS version control: DEVTESTING. When I originally set up DEVTESTING for use with TFS, my domain user, Nathan, configured the sole mapping we use, for example $/MyTeamProject -> C:\TeamProjects\MyTeamProject. Everything worked fine because it was the first time the working folder C:\TeamProjects\MyTeamProject was configured under the DEVTESTING workspace. I then logged in as another domain user, Elizabeth, to check the workspace working folder mappings and I noticed ...Show All

• Visual Basic New row in datagrid: Old values are overwritten instead of a new row appears

  First post from a not so experienced VS.NET/VB programmer I am writing a short piece of code that allows users of the program to enter some data in textboxes and then by clicking on a button, allow them to add the information they put in the textboxes to a datagrid. The first time they press this button, it shows perfectly in the datagrid on the form, but the 2nd time it only updates the first row instead of adding a new row. By doing some searches on Google, I found out that I am not using the right code, but I can't find how to do it correctly. I hope to get an answer here. Below you see the code I am using currently, I wanted to attach an image to show the screen of the application, but obviously as a ...Show All

• SQL Server Object reference not set to an instance of an object

  Hi all I m trying to access a server report through report viewer control. I got the error "Object reference not set to an instance of an object". I have administrator rights on the reporting server. I have created this report using Business Intelligence Projects. I am using textboxes and rectangles throughout the report. When I compile and run the project through Business Intelligence Studio, it works very fine, but when I try to access it through direct url or by report viewer control, it gives the above mentioned error. I tried to deploy a blank report (having no controls like textbox, label, rectangle) to the report server, but got the same error, "object reference not set to an instance of an object&qu ...Show All

• Visual Studio Tools for Office How to get addin install to work for non-admin users?

  I have built an installer for my VSTO addin which works fine under Outlook 2003 and 2007. I have code whcih sets the CAS for my add-in so it will run. The problem is that my installer won't run unless the user running it has admin privileges on the box. It displays an error saying you have to be an admin It installs on a per user basis as you can't get the VSTO plugins to install for all users under 2007. So how do I create an install which will work for non-admin users Hi, How does your security code work. One issue may be that if you are setting policy at the machine level then you need admin rights. If you are a non-admin you can only set at the user level. With the user policy level you can only not add policy for URLs o ...Show All

• Windows Forms Changing size and position leaves the selection handles behind.

  Hi folks, I am developing a Designer and therefore I do have a propertyGrid which I use to alter properties of my custom controls. However when I change the Location or the size of my custom controls the selection handles stay at the previous location or size. i.e. the controls will move to the new location but the selection handles will not. the same for the size. That naturally looks very ugly. I was wondering if anyone came accross that and could give me a solution to this matter. I tried to refresh() the control, design surface, the form loaded as a design host, the propertyGrid values in the case that would reflect on the control, etc... but all that did not work. I tried also to use the selectionService. setSelectedCom ...Show All

• Software Development for Windows Vista Questions about my ASP.NET scenario

  I have some simple question about my asp.net scenario. My web app has to manage a thesis request, from a student against a teacher. For the moment I consider a simpler view of the workfow. A student can do a request of a thesis and a teacher can approve or reject the request. We consider only this simple scenario. The questions are: 1)I have something like StudentService and TeacherService. Do I add these services at the runtime each time before a workflow instance is started (only when the student request the thesis) or I have to add them to the webconfig of my web project and then siply do a wfr = WorkflowRequestContext.Current.WorkflowRuntime; in my *.aspx.cs code 2)When the teacher connects He have in his web page all a datagrid (or s ...Show All
