View 6 RepliesI have converted a VB6 project to VB.NET and am left with a large number of inline 'warning messages' such as "UPGRADE_WARNING: Couldn't resolve default property of object varJonSkeet" that I would like to get rid of. Is there a way to do this within Visual Studio 2008? Will it be easier to remove the warning messages with regex? I would prefer to do the removals one file at a time, but it isn't a dealbreaker.

View 3 RepliesIt's been a while since I have posted. Good to be back. I am doing some scripting work using Visual Studio 2005 Tools for application. I am having an issue outputting to the debug window. My line of System.Diagnostics.Debug.WriteLine("Test") I have the output window open when I start debugging and am using the debugger. What happens is the debug window seems to go away when I allow the line to execute. After the line executes if I go back to the output window nothing is there. The message does not go to the Immediate window either.
View 5 RepliesI am using Visual Studio 2010 Professional in trial mode... and suddenly the Output window won't show my Debug.Write() stuff. It had been showing it for the past month.I have been using the 2010 version for 30 days (after upgrading from Visual Studio 2003) in trial mode. I just renewed the trial for the extra 60 days, and the "About Visual Studio" window says I still have 59 days left.
I have verified that the application is running properly, without errors. When I purposely generate an error, the Output Window properly shows the error and the stack trace I've already checked my Build>Configuration... it's in "Debug" mode, not "Release". The Debug.Write() text is not going to the Immediate window, either.One other point, I tried running the same application in the Visual Studio 2010 Express Edition, and it complained that it could not debug the specified code, though it did properly build it so that it would run in the build. Could Visual Studio 2010 Express have modified something in my project files to disable the debugging output?
I'm developing a Win Form application that can be run from the command-line interface. I'm looking for a way to print messages to console ("cmd") window.I've tried to use "console.writeline" but nothing was displayed. What am I miss? Should I redirect the stdout to the cmd window? If so - how?

View 6 RepliesI'm compiling a VB.Net 2.0 app (created in VS2008) using msbuild, and now I've added a generic return type, it's giving me the following:
Warning: Type library exporter
encountered a generic type instance in
a signature. Generic code may not be
exported to COM.
Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.
I have an app with a timer control, and the interval is set to 60000ms (1 min). so every min i have some event happen. thats pretty simple. however, i want to have a 15 second warning that the event is going to happen. so basically 45 seconds after my timer starts, i want a message such as "15 seconds left until event x happens".
would i have to use 2 timers? i guess im lost on the logic. i know how to use the timer control, but i have been googling all night trying to figure this one out. i have tried using 1 timer set to 45 seconds (for the warning) and another timer at 60 seconds(for the event) but they go out of synch after 1 iteration and will not consistently stay 15 seconds ahead of the other. i dont want to post any code i have, because it is all trash and i want to start over from scratch.

warnings got me thinking about old issues that always goofed me up when I was writing more VB.NET code.One of them was the fact that the compiler didn't warn if you declared a Function but never did an explicit Return statement or assign to the Function name. Running Visual Studio 2008, I just made a small experimental project, and it seems as though the behavior has never been fixed.I created a Visual Basic Console application, with the following code:
Module MainModule
Sub Main()
Dim test As Boolean = TestWarning()[code].....
I also went into the Project Settings and turned On Option Strict and Option Explicit.I also set the Warning Configurations so that "Function/Operator with no return value" was set to Error.I compiled the project and got no warning, and no error on the TestWarning() Function. This seems like a great place to put a warning, because it will default to False, and you may have simply forgotten to do a return. C# will error without a return statement. I thought that VB.NET did the same thing with the "Function/Operator with no return value" configuration. Is this a bug, or is there something I'm missing?
Edit: Further Experimentation
Function TestWarning() As Boolean
If DateTime.Now.DayOfWeek = DayOfWeek.Monday Then
Return False[code].....
If, and nothing in the Else, there is also no Warning/Error. It will simply take the default, even though you likely intended (via programming style) to have an explicit return. In this case, I explicitly returned False (which is the default for Boolean), so it's likely a hidden bug that I should have returned True in the Else.

I wrote a small VB6 program to monitor the status of a Shared Network Drive. In this case it's an external hard drive. The drive is used for backup. The program is invoked automatically when the computer is booted and runs minimized.
If the backup drive is not turned on or otherwise not functional then the program changes from minimized to a normal window and displays various statistics and a warning that the backup drive isn't working.
I want to make the warning much more prominent, like minimizing the program that happens to be running or displaying the warning window in front of the progrmam that happens to be running. I want something really noticaeble. The computers don't have speakers so I can't play an warning.wav .

Not a query, just mentioning a problem that might affect others, assuming it is not just some wierd bug on my system, that is. Perhaps someone can check this out.Under screen resolution, Windows 7 has a "make text larger option". On my machine at least, this has the effect of increasing the sizes/positions of any controls set in design mode. Not just in executable, it actually changes the values in design mode.
If you are relying on rescaling sizes/position set in design mode according to screen resolution only you may get incorrect positions when this mode is in use.This affects both VB.net and VB6.
I've been mostly working with VB.Net for over a year and just noticed this Am I going insane, or does VB.Net NOT have an "Unreachable code" warning? The following compiles quite happily with nary a warning or error, even though there is a return between the two writeline calls.
[Code]...
I misidentified the problem. It is actually like this:[code...]
Code analysis complains about this because ms can be disposed twice. That will only be true if zStrm, which takes the memory stream as an argument to its constructor, disposes of the memory stream when it cleans up. That seems like a totally nutty thing for the disposer to be doing. Does it really do that? Would a class that takes another class as an argument, be so uncivil as to dispose of that argument?
I suppose it would, since the alternative would be that the memory stream might not be disposed at all if it was created in the constructor like this:[code...]
I guess the only real question is whether or not I have to worry about this?

View 8 RepliesUsing VS 2005, I create a new VB .NET class library project. The project created is automatically populated with an "Any CPU" build target. I create a COM visible object, check the register for com interop and build the project. The resultant assembly is NOT registered in HKEY_CLASSES_ROOTCLSID. Instead it goes into HKEY_CLASSES_ROOTWow6432NodeCLSID. I have a 64 bit machine and 64 bit OS. I would swear that with VS 2003 on such a setup, I got an entry in the 64 bit registry hive.So I went to the configuration manager and specifically created a x64 config, copying from the (only) Any CPU config. But when I build I get two BC40010 warnings. One was for System.Data.dll. So I went to the project properties/References tab and then removed "System.Data.dll" (no mscorlib entry there - the other BC40010 warning) and then ran the add command and re-added System.Data.dll thinking that since I was working on the x64 config, the IDE would bring in the correct assembly.Still I get the warning. Why doesn't the IDE understand the meaning of the "x64" configuration the wizard created? The MSDN tells me I have to fix this:
To correct this error Examine the quoted error message and take appropriate action.Compile the program again to see if the error recurs.If the error recurs, reinstall the Visual Basic compiler.If the error persists after reinstallation, gather information about the circumstances and notify Microsoft Product Support Services.
