HELP! Trying to migrate from VB6 to dotnet 2003.... with MUCH frustration...

[Alex McMillan]

Hey - I know a bit about vb, written a few progs, upgraded to .net 2003 but
can't figure it out. Where has everything gone? Am I missing something
really obvious?

I'm trying to create a song-lyrics editing tool, pretty simple - a couple of
textboxes and a button or 2 to save/load from text files, but I want
something along the lines of a drivelistbox/dirlistbox/filelistbox combo
down the side to easily open saved files.

Also - how the hell would I do this in .net?

sub command1_click
form2.visible = true
end sub

??? seems im-bloodey-possible...

Any help much appreciated

Can't you use the FileOpen Dialog?

 

[Alex McMillan]

Well - I'm not exactly sure how that works.... and what I'm looking for is a
permanent box on the left side of the screen sorta like the 'folders' window
in windows explorer...

Like a tree control? But modified to handle folders?

Alex,

Like homer said you can use the File and folder dialog boxes.

You can drag those from the toolbox on your form and than enter the
properties to shart with.

Your question shows that you misses a lot of basic knowledge about VBNet,
maybe is this somethingh for you.

The global, auto-instancing, invisible variables, often causing much trouble
because people sometimes don't know what classes and objects are, and that
you couldn't get rid of (not the people but the variables...) in VB6 are
now gone - they are back in VB 2005. Do it like with all the other thousands
of classes: Declare a variable and assign a new object.

Hi,

Take a look at the vb power packs folder viewer and file viewer
controls.

[Alex McMillan]

Yeah - but, well... I'm a VB6 guru and have nobody to help me understand
..net, so how the hell a tree control works I dont know...

Maybe it's just a lost cause - thanks for your help anyway. I need to find
somebody who can walk me through a simple project and teach me how to switch
between forms.

THANKYOU thankyou thankyou thankyou!!!!!!!

I've been hunting for something like that for a couple of days now - all I
get is stuff I gotta buy, and living in New Zealand make's it nearly
impossible to buy a book from (e.g.) amazon.com - 'You must be a U.S.
resident to apply for an account' grrr

Thankyou more than anything!!!

Tried Gordon and Gotch? Mind you, I remember it taking a year for them to
special order a book for me.

Okay - here's where I become a newbie again...

Could you post a little bit of code so I can try and follow it? At the
moment I'm just writing a kinda 'notepad' lookalike - Ive added menu's and
want to open 'frmAbout' when the user clicks on Help-->About. I can't
understand how. In VB6 I would have just done it as above..
frmAbout.visible = True...

In VB6 I would have done it the same way I do it now:

dim f as new frmAbout
f.showdialog 'in VB6: f.show vbmodal

In general, if you want to access an object, you need a reference. If you
don't have it, you need to pass it. Using global variables was already bad
practice in VB6 because it works against the recommendation of
encapsulation. Passing variables is clearer because could simply pick some
classes and put them in a library without the need of unscrambling the
relations of the classes to modules (having relations to other classes
(having relations to modules (having relations to other classes....))).

showdialog!! there we go... now I understand...

Thanks a lot Armin - much appreciated.

Too bad I got impatient and uninstalled .net - replaced with VB6...

Didnt try, but would it be possible to have them both installed without any
'bad things' happening?

Am installing .net again now - just couldnt handle sitting at my computer
unable to code

Thanks again,
Alex

You can forever be the first after all those years that nothing happened
