• .NET Development Thread scheduling problem: (apparent) violation of "wait on event" mechanism between /CLR processes

  Out of all the available forums, this one seems to be the most appropriate for this issue. This certainly is a .Net-related problem because I have done this successfully in the past with native applications (using VC++ 6.0). I am currently using VC++ 2005 with the latest .Net on an up-to-date Windows 2000 computer with 512MB of RAM. The failure is observed with high-probability under low-memory conditions: after running two instances of the Studio (so I don't have to keep swapping the solutions when I want to consult the code), but only one debugger session (the other process is running as an executable), and the 2005 SQL Express server, I'm left with a commit charge of around 700MB, i.e., some processes are swapped to virtual memory.

• .NET Development Date.IsDaylightSavingTime

  From the docs, I would understand that this should return a boolean indicating if the time is within the daylight savings time interval. But I get a false for: Date.Parse("2006-10-29 01:58:00.000").IsDaylightSavingTime.ToString On that day in Eastern time, in the U.S that could be true . Actualy it is both true and false, that hour runs twice because at 2:00, we roll the clocks back to 1:00. Am I misunderstanding the method Is there any way around this mystery hour problem Any suggestions From docs regarding IsDaylightSavingTime: "Indicates whether this instance of System.DateTime is within the Daylight Saving Time range for the current time zone."

• Visual Basic Windows Service Timer won't fire

  I've been working on a windows service since last week, and the one problem that I can't seem to solve is getting my timer to fire. The service is supposed to scan a particular folder and deal with the files in it appropriately. The scan works perfectly, but at the end of it, it's supposed to start the timer so that it "sleeps" for five minutes before running the scan again. I say sleep even though it ends the sub and just waits for the timer tick event. I've tried using the timer in a couple of different ways thus far, from using timer.Start() and timer.Stop() in the scan sub, and enabling and disabling it (starting the timer in the OnStart() event). I've run the debugger on the process, so I've watched it run through the entire ...Show All

• Visual C# RadioButton and ApplicationSettings

• .NET Development Assembly.Load(): Fails once, fails always ?

  Scenario: Dynamic assembly loading: If an assembly does not exist, install it from the network. Consider the following code: 1: Assembly oAssembly; 2: try 3: { 4: oAssembly = Assembly .Load( "ClassLibrary1" ); // Will fail since assembly is not available. 5: } 6: catch ( Exception ex) 7: { 8: // Copy ClassLibrary1 to AppPath\ClassLibary1 folder 9: } 10: oAssembly = Assembly .Load( "ClassLibrary1" ); If you run the code above it fails at line 10, although the assembly is available at that time. It seems that when an assembly can't be loaded the 1st time, the application will not try to load it the 2nd time, even when it is available at that time. Is it possible to force the application to try to load it the 2nd ti ...Show All

• Visual Studio Interactive Mode pages

  I have the interactive page size set to 8.5 X 11, just like the actual page size. Shouldn't the page #s match in this case Or at least be reasonably close It seems like the interactive mode doesn't stop for the page when it should. I have several reports where they are drastically different and there are no toggle regions. One problem I just encountered is a table with a group in it. I have set the group to page break at the end. If the next page 'fits' on the interactive 'page' it doesn't actually break, whereas print layout shows this correctly. This seems like a bug to me since it is an explicit page break. ...Show All
