• Windows Live Developer Forums V3 performance degrades over time

  During my development, I had to refresh my webpage every so often. I noticed that over a period of time the map was taking longer and longer to refresh. In fact, at one point, it took 35 seconds. So, I decided to do some testing. With the help of the "window.setTimeout()" function, I automated the GetMap() function to run every 30 seconds. I calculated the time for the GetMap() function and saved it. It started out with 1 second and at the end of 30th call, it took 9 seconds. The increase was progressive and there were no spikes. I have 15 pushpins on the map. I'm using IE6. If I close the browser and restart my application, it starts running faster but gradually slows down again. In our production environment, I foresee my ...Show All

• Windows Forms How to tell a click on which item, which column in a ListViewControl?

  hi, How to tell a click on which item, which column in a ListViewControl I guess what I need to do is , get the mouse click event position, and test to see which item, which column has this position. But, don't know how to do it exactly. Thanks. Try something like this: private void listView1_MouseDown(object sender, MouseEventArgs e) { ListViewItem item = listView1.GetItemAt(0, e.Y); if (item == null) return; int x = 0; for (int ix = 0; ix < listView1.Columns.Count; ++ix) { int w = listView1.Columns[ix].Width; if (e.X < x + w) { Console.WriteLine("You clicked in column {0}, {1}", ix+1, item.SubItems[ix].Text); break; } x += w; } } ...Show All

• SQL Server How do you hide items in the Report Explorer Web Part?

  Does anyone know if it is possible to hide a report in the report explorer web part in sharepoint. I have a report that can't be run by itself.

• Visual Studio 2008 (Pre-release) Can an application either provide a service or consume the service

  I am trying to write a highly available Windows Service application, hosting a WCF service. There may be multiple instances running on multiple computers. However, only one of them is the master providing the WCF service and the rest of them are in the standby mode. I am thinking of adding a method to the WCF service so that the master and standby instances can communicate. This means that a standby instance needs to create a proxy of the WCF service. Since the code base is the same, it implies that it needs either to provide the service or to consume the service. It does not seem possible if there are data contracts and the call involves them. While I did get it to work when the data contracts are not involved, the workaround involves man ...Show All

• Windows Forms Change DB Structure without losing data?

  Hello I have developed and deployed an app using VB Express and SQL Express. The users have put data into the db. For a second release, I need to add fields to some tables.

  I am using a much modified version of the VB6 P&D wizard, calling DLLSelfRegister in VB6stkit.dll.

• Visual Studio Team System Use Rename Refactor to change the schema/owner of an object

  We have recently upgraded our SQL Server databases from SQL2000 to SQL2005 and would like to take advantage of the schema functionality in SQL2005 by reorganizing our database objects (tables, views, functions, stored procs) into various schemas. My understanding is that what in SQL2000 was considered the owner is now the schema of an object. Therefore all of our objects were previously associated with dbo as the owner and in SQL2005 now appear with dbo as the schema. Is it possible to use the rename/refactor functionality in VSTE for Data Pros to change the schema of an object from dbo to something else and then preview/execute changes to all locations that are referrring to the object To clarify t ...Show All

• Visual C# C# no header files. All code is written inline - why?

  Hi, Can someone explain "C# code does not require header files. All code is written inline" what is the advantage in going for inline how does it affect dynamic linking why dont we have header files as in C++ Thanks, Benin. Hi, Upon other opinions on this forums, header files are used on C++ to separete the definition with the implemtation. The main reason is that you can distribute your header files to third parties or customers with your DLL, so they can access to all the types and the compiler can warn you if there is any problem. C# actually removes the concept of header files BUT you can still do it in the same way as C++. That's why the "Interfaces" exists. Therefore you can have a fi ...Show All
