I will study the source data carefully when testing my UI!
I've just laid out a data bound WinForms form three times, the first two discarded with disgust because the databinding provided by the VS2005 wizard sucked. I was pressing back and forward on the BindingNavigator much better but the record detail was staying the same. Something was wrong, so I deleted the form and tried again from scratch. Same thing, so I try and create the whole data source again.
Then, on the third form, I notice that most of the records are for companies, who are allocated a range of phone numbers, and I have one record for each phone number, with ALL the other field values identical. then I noticed that clicking back and forward on the navigator is indeed changing records by my observation of the last digit of the phone number.

A few years back, I started a consulting engagement. We took over support of all client/server programs. Get this, it was a public utility and all internal databases were in Access. Anyway, there was a large complicated program written by a non-programmer. How bad was the code?
Well, if there was more than one way to connect to a database, the "programmer" used each type. If there was more than one way to do ANYTHING, they used every method. Then, to top it off, whenever we would make a change in one section of the program (tons of SQL) then another part would break. Each time a bug would be raised, it would be a few hours for fixing, testing, and fixing the sections that should not have broke but did. We stopped answering our phones at 4pm because we wanted to go home at 5. Otherwise, we'd work into dinner time.

Who cares about the skill level of the "programmer". Being written in Access is bad enough!

Yes, being written in bad enough, but, for SOME (very few) instances, that may be the best option available. There is a missions orgnanization near me that sends people to various areas of the world - they have no computer support near by, so, simple apps are written in Access for them to use... if they have to, they can probably ZIP the files to a floppy and mail them back to the support size if a program arises.
Again, not preferable, but what is best for them.

Live and learn! Programs like that is what made me so good at debugging. I was brought into a company to write a custom program and was later hired full time. One of my duties was to maintain and update their software. The first time I looked at the code I automatically wanted to rewrite it. I tried to fix the 350+ warning messages (most should have been errors), but doing so broke the code; that was out. Although I had discovered that touching a single line of code anywhere could break it, I soon learned how to modify it without breaking it.
Rule #1: Ye shall break down your code into individual stand-alone pieces, so that changing them has little or no effect on the rest.

Trying to track down a bug. Very simple little routine calls a few methods in an old COM DLL - some calculations and look-ups, nothing too special. Problem is, it only works once - if the routine is called twice in a row, it'll fail the second time around. Same inputs, same code to create the COM object, call a few methods, finish up... it just doesn't work twice.
So, i track down the code for this old DLL. VB6, which i haven't bothered to install in years, but i don't want to rebuild it anyway unless there's no way around it. Unzip the code and start browsing through it...
...and it's all forms. Except for a couple hundred lines in a .cls file for wiring up the COM interface, it's all forms. There is absolutely no UI for this damn thing, none, it exists only for some routine calculations and to retrieve a handful of numbers from an Access database... and it's all implemented by chaining 32 different forms together along with some sort of insestual communication between them.
I feel sick.

Sometimes its better to just trash things and recode. You get lost in the code and take 3 times as long to get done trying to patch someone elses work. Good luck with it.

Sounds like something a VB programmer would do.
|
|
|
|
|
Well, how else would you do it?
VB6 is all event driven you know, all you do is place a button on a form, and when the user clicks... oh, OK, maybe I can use SendKeys..., OK, back on track... wow, this really is as easy as the book said!

All VB6 programmers are not like that. I've done a ton of complicated stuff with vb6. it just that novices tend towards vb6 because of it's ease of learning factor.

I didn't say they were. I started my consulting career on a national client server system with hundreds of users, using VB6.
It even included vertical text headings for narrow report columns!

Fortunately, there's a VB-coding consultant working for us, so it looks like i can push the problem off on him...

You lucky sob!
I did not think VB6 programmers should have been writing DLLs to begin with, I considered it a ridiculous idea even when I was forced to use that language for the main interface. All of my DLLs and COMs where written in C or C++.
I have yet to decide about VB.Net.

That is the wave of the future – coding without understanding.
Modern MS languages are good for business – but it requires real programmers to create the frame works first. What that means is that people who understands how it all works decreases and the number of people who know how to use it increases.
Translation: If you know how it all works there are fewer jobs – If you know how to use it there are lots of jobs.

I've just stopped smoking and drinking at the same time, I'm working on abominable VB6 and VBA code between Acess and SQL Server, so I took on a little job for extra money, and I've just received the script for the table I am to code a front end for. Field names have been changed to preserve confidentiality.
The one redeeming point is that there is no code here, I get to insert fresh, sexy, new C# code.
CREATE TABLE "dbo"."clientTable" (
"oneField" varchar(8000),
"abotherField" varchar(8000),
"andGgain" varchar(8000),
"totalOf" varchar(8000),
"21fields" varchar(8000),
"like" varchar(8000),
"this" varchar(8000),
...
...
)
GO

INSERT INTO clientTable VALUES("a","b","c","d"....That's going to be fun - a database that's in negative numbers for normal form. I see that they don't want Unicode either; obviously because it takes up so much space

I surely don't need to point out that if the sum of field lengths used exceeds 8000 bytes, SQL Server will refuse to insert the row.
SQL Server 2000, anyway. SQL Server 2005 might do something different since it now supports varchar(max), but I think you actually have to use that syntax to get out-of-row varchar fields. SQL Server 2000 makes you use the slightly-differently-behaving text datatype, which confusingly can be set to be stored in the row if it's below a certain length of data.
(If you smoke and drink at the same time, aren't you in danger of putting your cigarette out?)

No, but I have just received the refreshing news that we have carte blanch with the databases for our development. This is a small company, and they are actually running seven different databases on the same server!
Not for too long I suppose.
