Exclamation(!) Operator Used On A Number?
Jul 18, 2011I'm looking at inherited code and I found this in a vb.net windows form:New System.Drawing.SizeF(6.0!, 13.0!)My question is, what is the significance of the ! (exclamation) operator here? Most of my searching for the exclamation operator ends up returning recordset format or the ! gets ignored in the search and I get hundreds of unrelated items.

May 15, 2011In my application I have bound a datagridview to a SQL2005 bindingsource.I really had to change a database field (more length allowed) and now de DGV displays red exclamation marks and states: 'Colomn 'password' exceeds the MaxLength limit'. (the 'password'-colomn isn't even displayed, but that's a sidenote).I tried different things but can't get rid of the exclamation marks. how I can manage this. I really don't want to create a new DGV, because there a lot of code and stuff involved.

View 3 RepliesPossible To Use Exclamation System Event To Validate Data Capture?
Aug 23, 2010In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.
When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.
My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.

View 6 Replies.net - Suppress COM Generics Warning?
Dec 8, 2010I'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.
Create A 15 Warning Before Timer Even?
Oct 6, 2010I 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.

View 6 RepliesNo Warning In .NET When Function Has No Return?
Feb 25, 2010warnings 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.

Unable To Display Warning
Jan 29, 2011I 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 .

Windows 7 Resize Warning?
Feb 11, 2010Not 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.

CA2202 Warning About Disposing Objects
Sep 26, 2011I 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 RepliesIDE :: Warning BC40010 In VS 2005 Project
Oct 8, 2009Using 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.
