Compilation And Execution
Nov 12, 2011
read the COMPLETE email before giving me instructions.I say that because it seams like who ever is responding is only reading part of the email and responding.I have followed your instrutions and I still can not get myhello.vb to compile.
Both vbc.exe and mylello.vb is in the same folder c:program files
"C:Program Filesvbc.exe myhello.vb"
You stated that I should run command prompt as administrator and tye the same command as you do. what (as administrator) is. Please walk me through the complete process. Please do not tell me to run the command prompt as administrator because I do not know what that mean.I can not speak to my administrator. Also I attempting to compile a sample VB that came with the software, so using Visual Studio is not the solution.

I have a vb 6.0 file that compiles a CLS file in the same folder to a dll without the creation of any windows forms. Does anyone know of an example for this in VB.NET?

I'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. For example, an application with just a blank form and nothing else will take about a minute to build, and then it will sit for another minute or two until the app window pops up. It didn't use to do this!

I 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?
vb.net
#Const Debug = True #If Debug Then Console.WriteLine("Debug")'I also tried:#If Debug Then : Console.WriteLine("Debug") : #End If'
But that didn't work either?

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.

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 am getting a project-level conditional compilation constant error while trying to build my vb.net project. It reads:
project-level conditional compilation constant 'VB_VER=9.0,TARGET="exe",CONFIG="Debug",_MyType="Console",PLATFORM="AnyCPU",DEBUG;^^ ^^ TRACE' not valid: Character is not valid.
I recently upgraded it to the latest version (from 2.0), and I have a feeling that this has something to do with it.

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.

What is the best way to keep my source code separate to the output from compilation? I can change the "Build output path", but I am still getting files created in the "obj" directory whenever I compile. I want to have a directory tree that only contains source code.David Streeter

I 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
Error 2 Too many characters in character literal C: cdotnetdevsrcvbmainRtestHelper.vb 1 1 Component Sources
The first line of my code is simply:
' Copyright 2011
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...)

Quote:Value of type System.Nullable(Of Decimal) cannot be converted to System I have the code below which seems to work fine on my development server but causes a compilation error when I put it on my live webserver (uncommented).The error message I get from the event viewer in IIS is as above.
' <WebMethod(Description:="Insert into Referral Payments Table.")> _
'Public Function InsertReferralPayment(ByVal ReffererCustID As Integer, ByVal InstalledCustID As Integer, ByVal AmountReferrer As Nullable(Of Decimal), ByVal AmountInstalled As Nullable(Of Decimal), ByVal ReferrerChequeSentDate As Nullable(Of Date), ByVal InstalledChequeSentDate As Nullable(Of Date), ByVal ReferrerChequeNo As Integer, ByVal InstalledChequeNo As Integer, ByVal InputBy As String) As Integer

From what I can tell IIS is configured the same and both referenced DataTables seem identical.

I have seen a different behavior before, but this time my application just doesn't work properly when debugging, while it does everything perfectly after compilation.
My project is beginning and does just one thing: monitor the clipboard and save its contents to a XML. It has just one form (frmMain), which, when loaded, puts itself in Windows clipboard listening, via WIN32 API. Then, whenever receives a message, the form has to check if it's from clipboard and, if so, saves the actual contents.
The code is below:
Public Class frmMain
Private Const WM_CLIPBOARDUPDATE As Integer = &H31D
Private XmlDocument As System.Xml.XmlDocument
[CODE]...
So, as I've said, after compiling, everything works perfectly. However, when debugging the "AddItems" function is never called. I set a stop point in the line Win32 API is called (in frmMain_Load) and the execution NEVER STOPS THERE! Debugging line by line, I found out that after executing some lines from frmMain_Load, VStudio just jumps to WndProc and never comes back to frmMain. I mean, the form is shown, and the rest of its initialization code is never executed. Because of that, my form is never added to clipboard listening (this command is at the end of frmMain_Load) and, consequently, all messages my window receives are not from clipboard, and, therefore, nothing is saved.
Is it normal to VStudio just bypass some code because a event triggered other method? This could lead to lots of complications and it's not consistent with after compiling behavior. A proof that what I said is actually happening is this: I passed the last 5 lines from frmMain_Load (where the Win32API is called) to the beginning, so my program would call the API before initializing the XML file. OK, now what I have: the API is called, but the XML commands are never executed. Consequently, "AddNewEntry" is called, but I have a null-reference error, because my XML was never initialized. Have you ever faced that bizarre behavior? What can I do so my debugging is correct and I don't have to compile my program for each test I want to do?

In the above code I am trying to recurse the LoadData function when the connection is unavailable, I want to defer the loading to when it becomes available. The problem is the above code leads to a compiler error, since a ByRef param cannot be used in lambda expressions.
