• Smart Device Development PPC device problem w/ VS2005 application

  hello all, i have a program that i upgraded from eVC to VS2005 using the eVC++ upgrade wizard add on. i was able to successfully upgrade the application (or at least i think i did), and it compiled correctly in VS2005. when i transferred the app over to the PPC device (running PPC magneto) and tried to run it, i get the following error message: "The file 'app name' cannot be opened.  either it is not signed with a trusted certificate, or one of its components cannot be found.  you might need to reinstall or restore this file" i'm thinking the problem has to do w/ the trusted certificate, but not 100% sure, as i've never dealt with one of these problems.  any idea thanks in advance, greg ...Show All

• Software Development for Windows Vista Passing parameters from the workflow to the host example request??

  WF Gurus, I am using XOML only state workflow from ASP.NET client (WF 3.0). I need to pass output parameter to the host ASP page before WorkflowCompleted event executes. Can someone please provide a code example of how this could be done Thanks in advance, John Portnov Matt, Can you please provide a code example to show how to bind the activity property to the local service (note I am using XOML only state workflow) Assuming I need to make the local service communicate with the host, I will take it from there and raise an event passing EventArgs from the local service.

• Windows Forms DataBound ComboBox

  Ok, I have a form with a datagridview and a details view next to it for each record. This datagrid is bound to DataBinding1, let's say. In the details pane, one of the controls is a ComboBox that is bound to a customer list / customer ID (DataBinding2). The customer name is the display member, and the customer ID is the value member. The data populates fine, and the ComboBox in the details view changes appropriately as you scroll through records. HOWEVER, when you change the value of the ComboBox, it fails validation, as if it is trying to store the display member (the name, not the numeric ID). I can type a simpe id that exists in the Customer database (i.e., 1), and it will pass validation and store the changes. Any ideas why it is not s ...Show All

• SQL Server New Login - SQL Server 2005

  I need to create a new login that can only see 2 Views. I have tried everything, but when I connect to the server with MS Access or MS Excel, and sign in using that Login, I can still a bunch of views. I only want this Login to be able to run either view and not see anything else. This is what I have done so far: 1) Created Login zzz (w/ SQL Ser Auth) 2) Set the default database to database abc (Nothing is selected in Server Roles) 3) Set User Mapping to database abc, user = zzz 4) Database roll membership is public. (It won't let me change it) 5) Added user zzz to the two Views (Granted Select only) Now when I connect to the server from Excel Select new database query, add new dat ...Show All

• Visual Basic Problem in using Try/Catch/Finally

  A textbox(T_TextBox) is bound to a float-type number in a database. The innitial value of the textbox is from that column of the database. I used these codes in my program: Dim T as Double Try T = Double.Parse(T_TextBox.text) Catch MsgBox("Please enter a number for T.") Finally End Try The problem is: every time before I run the program, a message box saying "Please enter a number of T." shows up. This problem only happens at the very beggining. When I change the text later (I select another number from the database, and this is done through a combobox), this message does NOT show up. Anyone knows how to get rid of the msgbox at the begging Thanks, Lili Thanks a lot, ...Show All

• Software Development for Windows Vista Vista Certification Test Cases V1.2 Test Case 18

  Hi, Test Case 18 states "the Upgrade Code in the Upgrade Table must be identical to the Upgrade Code in the Property Table. This means the application properly prepared for upgrade to address the previous package and properly prevent an older package from installing over a new package.” Apart from the wording being slightly off We're not sure why we would need to list the Upgrade code from the property table in the Upgrade table for the same installation. My understanding was that the Upgrade table was for Major upgrades where the product code had changed. Could someone clarify why this is a requirement and what the benefits are Regards Julien: I agree, how are we to detect older versions while still c ...Show All

• Commerce Server /Hi Can I rename a Commerce Server Site?

  The name of the site I'm building has changed, and so I need to rename the site in the Commerce Server Manager. How can I accomplish this. i'm aware I'll need to change all references in the web.config for the site, but in particular, how can I change the name of the site in the CSM Thanks, Dave Hi Dave, The supported way is packing and unpacking your site. You may need to change certain references in your web.config if the packager didn't pick up on the proper attributes to auto-replace. The unsupported way is by changing the tables in the MSCS_Admin database, modifying the web.config, and csapp.ini files. Cheers, Colin ...Show All

• SQL Server Which Server

  Hi Guys, I'm a beginner with Access and I set up a small database for a local charity project with a backend, front-end over a network drive. The database works well except that when too many people have the database open (there could be up to 6) at the same time it runs very slow. Someone said to me that if I put the tables on a server on one of the computers then it would improve the speed of the database but I would still like to keep the front-end as Access. Can anyone tell me if this approach would be a solution to my problem and if so which server would suit my needs, remembering that money is an issue This depends on how you have your system currently configured. Is your front end compo ...Show All

• Smart Device Development Question about .NET CF Runtime

  Hi there, I'm in the end stage of my first program, and I was wondering if there's a way to deploy a program with the .NET CF Runtime, so that there is no additional file(s) needed to be downloaded. Thanks, Martina all Windows Mobile 2003SE/2005 devices I believe come shipped with .NET CF 1.0 SP3 so you shold be good to go. As for .NET CF 2.0 , I am unsure.

• Game Technologies: DirectX, XNA, XACT, etc. Primitives appear grey (black when lighting is enabled)

  I posted this in the Framework forum (seemed to make more sense there), but there seem to be more people active in this one, so maybe worth posting a link: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=692742&SiteID=1 If I turn lighting on, my triangles are black. If I turn it on, they're grey. They're supposed to be read. Full source linked from that post :) I think the problem has something to do with the BasicEffect, though I'm not sure where.

• SharePoint Products and Technologies IE Crashes on view of Office document on SPS2003

  We've been running Sharepoint 2003 for a while and are beginning our migration from Office 2003 to Office 2007.
