I am looking at moving my company's internal business app from VB.NET to PHP. Some of the people were worried about losing GUI features that can be found in .NET. I am under the impression that with the right javascript framework, anything in .NET GUI can be replicated. While I am still researching this point, I would like to ask if for...

Is there a utility out there that will create VB.NET classes from a Dataset.xsd file? And I don't mean like the XSD.exe utility does - all that does is convert the XML of an XSD file into classes in a .vb - it doesn't append any "extended" functionality. I'm basically looking for something that will generate the beginnings of a busin...

OK thought I understood IDipose but just reading the best practices section of Accelerated VB.NET and it states that "The object doesn't contain any objects that implement iDispose, so you don't need to iterate through the containment tree calling iDispose" Is this "containment tree" just what the program know's he has used and then dis...
I don't even know what this is called. But some Windows apps used to have a "?" near the X in upper right corner. You could click that and then click on something on the screen and get help. Anyone know what that's called or (better) have any pointers to instructions on how to implement it? Oh, and I'm using vb.net 2005. ...

I recently had to write some code which parsed a file to set data in an object. As there were several objects and corresponding files involved here, I decided to separate the parsing code out. So I then had one class for parsing the files, CommandFileParser, and two classes per file/object type: one for the actual object itself and one ...

In C# if I want to create a "Custom Event" you do something like this: private EventHandler _MyEvent; Public Event EventHandler MyEvent { add{ _MyEvent += value; } remove{ _MyEvent -= Value; } } protected void RaiseMyEvent() { if(_MyEvent != nul) _MyEvent(this, EventArgs.Empty); } In VB this is not so straightforward n...
Hello, I need to use one of my VB.NET projects in a C++ project. The interface between the two will be for the C++ code to instantiate and call methods on one of the .NET assembly objects. Both compile to DLLs (and then the C++ DLL is loaded from the NTVDM as a VDD, but that's probably not relevant.) If possible I would like to avoid u...
