• Software Development for Windows Vista How do I have my app update itself if it can't write to the installation folder?

  I have an app I sell that presently is designed to update itself when a new version is available and the user opts to update. My approach is simple. I install two programs: MyApp.exe and MyAppUpdater.exe. When MyApp needs to be updated it starts up MyAppUpdater and shuts down. MyAppUpdater downloads a new version of MyApp saving it to the installation folder as MyApp.tmp. It then verifies that the entire app was successfully downloaded and if so deletes the old MyApp.exe and renames MyApp.tmp to MyApp.exe. Works fine and saves my users from having to download the entire installer, uninstall and reinstall. If I understand correctly it look ...Show All

• Visual Studio Team System So what happens when Orcas comes out?

  Will the people buying TFS and TS right now need to pay for an upgrade I would bet on it. Microsoft is shelling out the bucks to build it, so I would assume they would want to have a return on that investment. ...Show All

• SQL Server Failing to "Jump to report" from hyperlink

  I am designing a report and have a text box containing a hyperlink that should navigate to another report when clicked.  In the "advanced textbox properties", on the naviagtion tab, I have clicked "Jump to report" and selected the report I want to jump to from the drop-down.  (The target report is in the same folder) When I preview this from the IDE, all is OK but when deploying to the Report server, clicking the link just brings up a blank page which fails to show the 3 parameters for the target report.  Changing the target report's defaults has no impact also setting the Parameters from the Navigation tab in the t ...Show All

• Visual C# Exceptions in designer - how to find?

  Hi, I have a control added to a form and whenever I open that form it tells me that an exception was thrown in the control and thus it's disabled in the form. However, I can't seem to find where this exception is thrown and everything is fine at runtime. Is there a way to break on exceptions at design time Thanks, Tom The immediate window is included in Visual Studio 2005 beta2. You are most likely to find the command that opens the window in the Debug->Windows menu. Best regards, Johan Stenberg ...Show All

• Visual Studio Team System Extended properties

  I'm just playing around with the product and noticed that the generated update script includes drop statements for extended properties which we use for column, table and constraint descriptions. Just had a quick look throguh the documentation, but couldn't find anything about it, is there some sort of support or a best practice to handle them TIA Hi Gianluca, I think you may have run into something which didn't make it into CTP3 - Import Database Schema is currently not adding extended properties. For deploying a project, there is a workaround: - Add all of the sp_addextendedproperty into the postdeployment.SQL file in t ...Show All

• Visual C++ Compiler error - HELP

  Hi all So I just converted a huge project from MetroWerks CodeWarrior to Visual Studio 2005. The project converted fine and ran... ran I said, since now I cant run anymore. What did I change, well, I was changing some setting with 'struct member alignment' and trying some #pragma pack(1). After some tests I changed it back to default, and removed the pragma's. Now the code runs, but not very well, since some members of structs are not being read correctly anymore. example: class CA_QueryObj { public : CA_QueryObj( char *inFunc, char *inQuery, long inType,Boolean inAutoDelete); ~CA_QueryObj(); char function[1024]; char query[4096]; ...Show All
