• Visual Basic my first DLL: Class is visible but not Functions

  I'm learning how to write a DLL in VB Express 2005. It compiles fine: Public Class Common Public Function FourTimes( ByVal x As Long ) As Long FourTimes = x * 4 End Function Public Sub SayHello() MsgBox( "Hello from Pearl4.dll" ) End Sub End Class Then I create a TLB library file, which also appears to work fine: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm.exe C:\Windows\System32\Pearl4.dll /tlb I want to access the functions in VBA, so in Access I added a Reference to the TLB, and now I can see the class named Common, but neither of the two procedures. How do I make them visible Thanks for your help. Henry You'll need to either c ...Show All

• Visual C# compile incompatibility: "/mt" and "clr"

  I am trying to write a C++ wrapper for my Csharp code -- essentially to go from "unmanaged" to "managed" code. I used some samples on the internet as a basis but have hit some issues when compiling in Release mode v. Debug mode.... It works fine in Debug mode ! It fails in Release mode : " D8016 " /clr and /mt are incompatible (etc.) I am using VS2005 and it seems like some things have changed with respect to the "clr" compile switch. It's frustrating because it works when compiled in debug mode. I have tried everything to resolve the compatibility issue, but it seems like VS2005 just overrides the options at run time and forces "/mt" on me (even though I change it to "/md&q ...Show All

• Visual Basic VB2005 Upgrade, or not?

  Hello, I am not sure if this is the right place to ask this question, but I couldn't find anything more fitting. I am considering getting the Visual Studio 2005 IDE, but I have a reservation. I currently have VS2003, and have heard that the .NET 1.1 framework is falling by the wayside, so to speak. I have used the trial version of VS2005, and like it very much. However, I have heard that VS 9.0 will come out soon, and I don't want to have to upgrade again in a year or two. So, I guess my question is, is VS2005 going to be viable long enough to make it worth the purchase Is Microsoft making the higher level languages like Visual Basic "disposable", in other words, changing every few years Please, don't take me as being an ...Show All

• Windows Forms NotifyIcon and fileSystemWatcher issue

  Greetings, I am writing a fairly simple app that uses a NotifyIcon and a FileSystemWatcher. The idea behind this is to alert users who share a resource to that resource's status. We have about 15 users who utilize this resource but only one can use it at a time. I want to use the NotifyIcon to display the status of the resource (in use or available). A user selects an option from the NotifyIcon menu (logging in or logging out) which updates a central xml file. The FileSystemMonitor monitors the xml file for changes and triggers an update to occure for each NotifyIcon running changing the Icon image and popping up an message bubble to the user. The problem: This all works as expected of only 1-4 instances are monitoring the XML file. But if ...Show All

• Commerce Server Site Unpacking Error Creating URL?
