I have a problem with the VB.NET compiler failing to compile a class (in a separate C# assembly) which contains two overloads of a method with generic arguments. The equivalent code in C# compiles against the same assembly with no errors. Here are the two method signatures:
protected void SetValue<T>(T newValue, ref T oldValue)
protected void SetValue<T>(T? newValue, ref T? oldValue) where T : struct
Here is the code to three assemblies that demonstrate the problem. The first is the C# assembly with a Base class that implements the generic methods. The second is a C# class derived from Base and calls both overloads of SetValue correctly. The third is a VB class also derived from Base, but fails to compile with the following error message:
[Code]...
Am I doing something wrong in the VB code, or are C# & VB different when it comes to generic overload resolution? If I make the method arguments in Base non-generic then everything compiles correctly, but then I have to implement SetValue for every type that I wish to support.
I'm running 64bits Windows 7 and using MS Visual Studio 2010. I'm doing a VB program connecting to mySQL database using 32bits ODBC connection. the program have no issues loading crystal report in Visual Studio IDE environment. However, after Build and install in the same machine the following error msg appeared when trying to load the crystal report with data call from database (ABLE
to display report when NO data call):

We were working with a VB.Net app that contains something like 2200 VB modules/forms/classes and got a not-uncommon error message when we went to compile it. (Didn't write down the exact message, but it's basically unable to copy an image file that's in use.)Problem, of course, is that not everybody got out of the app when we told them to. Like I said, not uncommon. (It's a shared app that runs from a server.)Now, the weird thing. After kicking the offenders out, when we recompiled the program the image, which we use on search buttons, was gone. The file was still there but all of the property settings that referenced it were gone. Looked into the Designer code & they were gone from there, too. Seems to me that a compiler should *mark* the code that won't compile, not delete it.Anyway, I only see two courses. Either we restore our app from a backup, losing all our changes, or we go thru all the forms (like I said, there are 2200 modules-not sure how many are forms, but it's a bunch) and manually replace the properties on all the search buttons. Either way it's going to cost us at least a day's work.
View 2 RepliesI am getting the following compilation errors from Microsoft Visual Basic 2010 Express on the first line of my code:
Error 1 Newline in constant C: cdotnetdevsrcvbmain estHelper.vb 1 1 Component Sources

The first line of my code is simply:

It is generating the same compilation error for all my comments. Does anyone know why MS VB Express 2010 is acting this weird? Comments in visual basic are supposed to start with a single apostrophe so I don't understand this weird behavior.
I'm using access to replicate something that is very simple in excel. I have one "due date" column, and I want the cell right next to those cells to tell me if there are less than 15 days to that date. In excel is a simple conditional function, but I want to do it in Access because it looks better.I'm new to access and even though I've been reading some posts and forums I haven't been able to pull this out. I tried to program a macro with the following
Sub Alarma()
[Alarma] = IIf([Fecha de vencimiento] - 15 > Date(), " ", "Faltan menos de 15 d�as")
[code]....
It shows the following error -> Compilation error: External name not defined.
So, it's not reading the "Alarma" field... how do I define this field? It's inside a formulary, and Alarma is the title (I downloaded a template from the internet and changed the titles so I wouldn't have to do it from scratch...)

View 2 RepliesI'm using Visual Studio 2010 Pro on a Windows 7 PC, to build simple VB Windows Form Applications (I've just started learning VB). Lately when I try to debug my applications, it takes unusually long.

It didn't use to do this!
View 1 RepliesI have tried looking at "related" questions for answers to this but they don't seem to actually be related...Basically I have a VB.Net application with a catalogue,administration section (which can alter the catalogue, monitor page views etc etc) and other basic pages on the customer front end.When I compile and run the app on my local machine it seems to compile fairly quickly and run very fast. However when deployed on the server it seems to take forever and a day on the very first page load (no matter what page it is, how many stylesheets / JS files there are, how many images there are, how big the page markup is and so on). After this ALL the pages load really fast. My guess is this is due to having to load the code from scratch; after that, until it is recycled, the application runs perfectly fast. Does anyone have any idea how I could speed this part of the application up? I am afraid that some customers

I have a project in VB.NET 2010 (compiling to x86, .NET 2.0 runtime) that I want to compile into two separate EXEs - a "lite" version and a "full" version. Unfortunately I cannot make two separate projects as it uses the Adobe Reader COM control - and sharing a form using that control between two projects seems to confuse the IDE (something to do with COM Interop, I assume - if someone knows how to share a form hosting the adobe reader control, that would solve my problem too).
I have found this thread: C#: VS.NET: Change name of exe depending on conditional compilation symbol however I don't have any MSBuild experience so I need more explicit instructions. On the "My Project>Compile" tab there is a "Build Events..." button. I was wondering if anyone knows how to set a conditional compilation constant and use that to determine the EXE name (or change it after build). If all else fails I can rename the EXE manually I suppose, but I'd prefer it to be automated.
How can you write a #If statement on a single line?

I've got a problem with a program that references a third party ActiveX component that I've been refused permission to distribute. The AX component is used on some user defined controls which the user can add programatically, which makes isolating them fairly easy. However, the problem is that if the program is installed on a machine without the third party component then it just crashes, where I would much prefer it to just alert the user to the missing component and then disable the functionality that requires the component.
In the past I've tried adding the reference programatically but have found that this solution doesn't work with this particular control.

In Debug mode my application compiles to a 4MB .msi file plus setup.exe at 368kb, and the installed app includes the .pdb file @ 2.3MB. If I change to Release mode I'd expect to avoid including the debug symbol file and considerably reduce the .msi size, but surprisingly the .msi goes up to 4.45MB and setup.exe to 420kb. Am I missing something here? I want to reduce the upload size of the application by avoiding the unnecessary debug file, but clearly I've misunderstood what's happening or maybe what I can do.
