Visual basic is10/5/2023 ![]() ![]() Microsoft and HP were interested in creating an ISO standard language, which was the original goal, however HP dropped its support, and the ISO computer language never materialized as an International Standard. ![]() NET and C# use the same CLR (Common Language Runtime) today. (Microsoft's claim to fame with its operating system was to free consumers from hardware-specific devices by encapsulating those tasks within its operating system.) Code became "portable" due to the compiler, and in fact, both Visual Basic. Programming was hardware dependent by design more so for marketing reasons than to preserve the logical composition of programming that should transcend hardware. BASIC (Beginner's All-purpose Symbolic Instruction Code) was developed in the 1960s as a method to overcome the difficulties of using assembly language written for processor-specific and/or brand name specific mainframes and hardware. See Comparison of Java and C Sharp for more on this topic.īASIC's roots go back to Dartmouth College. Java and C++ are two other programming languages whose syntax is also based on the C syntax, so they share a common look and feel. NET Framework.Ĭ# and VB.NET are syntactically very different languages with very different histories.Īs the name suggests, the C# syntax is based on the core C programming language originally developed by Dennis Ritchie at Bell Labs (AT&T) in the 1970s. NET are the two primary languages used to program on the. Just so you know, the debugger says that the null object is comp.C# and Visual Basic. I've looked through VB books, searched several forums, and everything that SHOULD work doesn't! Sorry for asking such a remedial question, but I just need to know. If ((Not (comp.Container Is DBNull.Value)) And (Not ( Is DBNull.Value))) Thenįor i As Integer = 0 To () Step 1 ![]() If ((Not IsNothing(comp.Container)) And (Not IsNothing())) Then If ((Not IsDBNull(comp.Container)) And (Not IsDBNull())) Then All I want to do is check if an object is null, but no matter what I do, if it compiles, it throws a NullReferenceException just trying to check! Here's what I've done: If ((Not (comp.Container Is Nothing)) And (Not ( Is Nothing))) Thenįor i As Integer = 0 To () - 1 Step 1įixUIIn((i), style) ![]()
