String Concatenation.
VB does do a poor job of string concatenation - but there are ways around that. The problem lies in the memory management involved in resizing the string. The solution is to create a fixed length string of desired size and then replace the contents of the string with your data.
That is a really sad statement. Maybe you should start trying to improve your skills and stop complaining. It is possible to write poor code in any language. Unfortunately, the ease of use of VB allows below average programmers to pass themselves off as lead developers when in fact they have a minimal grasp of the language. A good good developer needs to have a grasp of the the way the language operates. A good understanding and knowledge of the strengths and weaknesses of any language is essential. If you don't have the patience to learn the language fully, perhaps you should switch to another language or stop calling yourself a programmer. VB has a bad reputation as it is, it doesn't any more below average programmers writing buggy apps...

The trouble with BASIC variants, including Visual BASIC and Dark BASIC and Power BASIC, is that the languages tend to grow in all directions at the same time, with whatever mish-mosh of features seem good at the moment. After a while, that's what drives people away from languages like this. You need to spend a good amount of time becoming a Visual BASIC expert, and it keeps getting more complex with each release. Eventually it's easier to go with a language with a slimmer core.

Seriously, I like the idea of having a good/great language with a kick-ass IDE. The danger is that a mediocre/bad language with a kick-ass IDE will survive because of the IDE. When the limitations of the programming language become a real problem, there will be too much time and effort invested in the project to back out. This is what happens with a lot of VB programmers; people I know who have used VB (I'm not one of them) hate it with a passion. A better approach is to develop the IDE around a good language like python (which I use all the time); everyone I know that knows python loves it, and it scales well with increasing project complexity.

One of the reasons Windows spread to the desktop so well is because of its wealth of applications. The biggest cause of this wealth of applications was Visual Basic-- a language/IDE that would allow even the beginning programmer to create a useful application for the everyday Joe.
As a seasoned C++ programmer, I fully agree that any BASIC variation could never perform as well as its C++ counterpart. However, as a seasoned network administrator, I can also tell you the sole reason our corporation uses Windows is because one of the critical applications is a Windows only application. While C++ and most other languages provide better performance and control than BASIC variants, a good majority of applications in use dont require such performance and control-- and having a pool of programmers that is 10x as large to choose from usually makes for a better application in the end.

A source code converter would be better. (Score:1)
It seems to me that Microsoft put efficient tools into Visual Basic because the company wants to make sure it doesn't deliver a good programming tool. It isn't Basic that people like, it is the tools available in VB.
Visual Basic is written in C and C++, I understand. Microsoft wants to make sure that its customers are not able to become good enough programmers to compete with its own products. That's why it delivers efficient tools for a ridiculously bad language.
Most people don't seem to realize that the limitations of Microsoft products are deliberate. Windows 98 crashes because there is a deliberate limitation (of 128 K memory, I understand) in GDI and User resources. Exceed those limitations, and the operating system crashes without warning. Deliberate limitations like this are the action of a monopoly wanting to insure that the customers always have a reason to upgrade.
(Run Microsoft's own Resource Meter software in Windows 98 to see the limitations in action.)
It is a challenge for open source software creators not to get involved with Microsoft's destructiveness. Possibly what is really needed here is converter to take source code from a VB program and turn it into source code in a sensible language.
If the conversion could go in both directions, the need to write in VB would completely disappear. This is the desired effect. The present plan, of providing a VB-like language in open source software has the negative effect of encouraging VB programming.

Re:A source code converter would be better. (Score:2)
A difficult task, at least if you wish to make it platform independent at the same time. A lot of VB's "power" comes from it's ability to use COM stuff, which makes stuff like
Set xl = CreateObject("Excel.Application")
xl.visible = 1
possible (This pops up an Excel window, in case you couldn't guess).
But if you were prepared to shift languages but keep with win32 for simplicity's sake... I don't see any real barriers to mechanically converting VB to, say, Python. In fact, it should be dead easy - Python has all the features of VB, including COM support, plus ALOT more.
The trick would be converting it to efficient code, i.e. noticing certain idioms and converting them to Python equivalents - it'd make no sense to use the Scripting.Dictionary object in Python, for instance. The only feature of VB that I can't immediately think of a Python equivalent for is it's "With" statement... which would hardly be hard to cope with.

Visual Basic is a very poor language. The form editor isn't bad, the Object Browser quite handy, the IDE is so-so, but the language is terrible. Here is some food for thought:
Arrays. Say you've got a function which returns an array of some sort - let's say an array of variants to make it easy. How do you return an array of 0 items cleanly?
Object-Orientation. Ever attempted type-safe inheritance or polymorphism in VB? Variants do not count.
String Concatenation. Say you have an HTML page being generated by an ActiveX component called from ASP in IIS (apologies for the MS jargon... this really happened at my workplace though). If you are generating a table, and it has, say 20 columns by 100 rows (or in our case, sometimes more), you naturally would simply generate a big string of the HTML and pass it back to the ASP to spit out, right? But in the process of generating those 2000 table cells, you do quite a few string concatenations. Here's the problem: VB's string concatenation is O(n^2)! (as according to MS, apparently, not to mention our own testing). It can take many seconds or even minutes to spit out something that should be done in a fraction of a second. In the end we wrote a "FastString" component in C++ and used that in the VB. It instantly brought one test case down from 8.5 minutes to 2.5 seconds. Not exactly what I'd call getting a "job done quickly".
So, the obvious question: What's the alternative that's so much better, huh? As a matter of fact, I do have one in mind: Python. It does everything VB does, and much much more. The language is a lot nicer than Visual Basic. *Especially* for beginners. The in-built types are just so much more powerful. Lists and dictionaries being integral parts of the language automatically makes those simple jobs much simpler. (Yes, I realise there is Scripting.Dictionary for VB, but it's not as convenient.)
More impressively, with Python you don't hit your head against a brick wall when you decide to attempt something larger than 50 lines - it's a language that scales well between beginners *and* experts.
If you're wondering, yes I do hate VB with a vengenance, and I code in it (almost) every day. I feel qualified to rant.

An easy language, and a good graphical developmnet environment will encourage development of small programs that scratch the itch of the average user.
Back in older times when my dad bought our first computer (commodore vic 20) I started doing Basic. This continued on the commodore 64, and on our first PC it was gwbasic.
Then I accidently stumbled accros turbo pascal 5. I tried to take a program I made in gwbasic and converted it to pascal (thank god for the excellent help function in turbo pascal), and I discovered that it ran many times as fast on pascal.
Well perhaps others will try the same. Writing
10 print "Hello world "
20 goto 10
is sure an easy concept to begin with.
Besides that for many apps it isn't necessary to have the code highly optimized.

3 types of NULL? Hmm..
I can think of four: "Nothing", "Null", "Empty" and "Missing". Oh, and if you declare a variant array like this:
Dim fred() as Variant
but never ReDim it, then IsArray(fred) will be True, but both UBound and LBound choke on it. That sorta counts in a bizarre sort of way.
Btw, does anyone know a better way to detect if something is set to "Nothing" other than if typename(foo) = "Nothing" then ..., or catching errors?

Yes, it had a Palette command that was incredibly slow... you were much better off using:

(I think... it's been a while)
Incidentally, QBasic did have a logical and, but I didn't use it in that program... you're probably confusing the notation for hex with that. The and operator was simply "And", IIRC.

Core libraries should be shared with Gnome Basic (Score:3)
Now, before everyone starts screaming about viruses and the need for this, let me add another thought. At least for Gnome Basic, Michael Meeks was very conscientious about making gb have a secure sandbox from which an evil virus could not escape. The worst thing that can happen right now is DoS RAM consumption.
Also, there is an actual need for Basic in both Gnome and KDE. If we are going to capture any portion of the business users, Open Source must offer spreadsheets and word processors which are compatible with Micro$oft Basic. A large number of companies have huge collections of pre-existing documents which *must* work correctly or they will never even consider switching to Linux/BSD. Gnome Office and K Office must provide this capability before they can make serious inroads in the corporate world.

To all of you Linux Hypocrites out there who are spitting on a legitimate GNU/Free Software project, I have a few words for you. KBasic could, in fact catapult Linux onto many corporate desktops almost overnight, I would like to remind all of you that if it were not for the toolset M$ provides to actually code something for the Windows platform, I don't think that corporate America would have remained stuck in Windows for so long.
Certainly Visual Basic is is one of those tools. The bottom line in corporate America is that a button is a button and a combo box is a combo box, and a text box is a text box. Corporate America wants tools that are easy to use so they can:
1) connect to their databases
2) put stuff into them, pull stuff out of them,
3)and maybe show the user a little something along the way.
It seems like the KBasic team has the vision thing and all of you who posted negatively about a VB or Basic clone, will be kissing their feet in a few years.
Once again, good luck to the KBasic team.

Forget the language - it's the IDE that I want.
This is probably the ONLY thing M$ has done right - an IDE that has a "forms" editor (to lay out your windows), an attribute settings editor (to modify controls), code editing windows (intrinsically tied to the controls*), and controls to drop on the form, to build the forms easily.
I don't know of any comparable system for Linux (now, I know I am showing my lack of Linux knowledge here - I am sure there are good IDEs, and code editors, and maybe even form layout editors for X - who knows? - I just haven't gotten to the point of investigating about them yet). I know there is some similar things for Java...
After I learned C/C++ (stronger in C than C++ - yes, amazingly I am a coder who knows about both!), I realized that what I wanted was the ability to have an IDE like VB's, but the ability to write the "glue" code in C/C++ (and glue code is what most of VB is - it is almost possible to build an app in VB, that does useful work, without writing a line of code - that isn't to say it will be a perfect app - nay, one needs to add code to add exception handling, so that one doesn't screw up a DB table or something). Such a beast has yet to appear - the closest I have seen has been some of the Java IDEs.
If this could be done - if the Linux dev community can see past it's arrogance (yes, VB is limiting in some respects, but it is also very powerful - if only in the RAD arena alone - once you know how to leverage it, it can be great for many types of applications - Quake clone? Unlikely - Frontend for data visualization - Done every day), they would realize the importance of the IDE, and not of the language (this also assumes the IDE will be extractable from the rest of the code).
(*) - This is one of the powers of the VB IDE above VisualC (and the few other IDEs for other languages/platforms). With VisualC, one must build the form(s), then build the code, then do a wierd "hooking" process to "attach" the code to the various events that the form sends out, so that when an event occurs, the code is executed (and overrides a default action). Then the programmer can compile and link the app to form an executable. I like the way VB does this - just double-click the control, select the event procedure to override, and code - then compile to "test" the app. A real RAD tool...

Anyways, of course they have a right to do whatever they want with their free time, but I hope that all the designers are aware of the great choices out there.
Really, the key to Visual Basic is that you can easily add a new widget (component, VBX, whatever) and have it integrate smoothly into the designer. Without that feature, these GUI designers are really just going to be toys, sadly.

Their (yuck!) Win32 port closely resembles a (yuck!!!) VB clone, but at least it works in wine.

without remaining compatible, though, unfortunately. More fragmentation in programming languages ("this program requires xyz's implementation of the abc compiler, version 1.23.45") is just what we need (not).
Still, KBasic is probably a good idea - it will make it much easier for VB programmers to port their stuff to real OSes.

While there's no really working free JDK (kaffe still isn't there, probably some time in the future...), there are other reasons not to do Java.

No way. KDE doesn't have a bluescreen module, a "send-everything-to-microsoft"-feature (aka windowsupdate.microsoft.com), useless drive letters,
KDE is just trying to make the transition from a broken OS to a real OS as easy as possible, which is a good thing.
