Re: array style codeprovider in .net - Visual Basic Discussion Boards

I'd like to allow my users to write code statements in array format, for instance

c = a + b

where a and b are really a() and b() arrays.

Any ideas how I could do this? I've checked math code parsers, but none of them seem to do arrays.

Thanks!

In what context, are you writing a library ? What are the rules for adding two arrays ?

Well the math is array math, as in c++.

OK, I clearly need to be more specific.

I'd really like to create an intellisense-capable editor that would allow my users to write and see their errors in vb.net code. However, for a few functions, I'd like add c++ type capabilities, such as:

c = a + b

where c a and b are actually arrays.

other relevant array operators are < > = - / *

Maybe the first question should be how to implement the intellisense editor.

Thanks again.

Hi,

you want to define your own type (class or struct) and use operator overloading.
Look for some articles here at CodeProject on such things as complex numbers, or big integers;
that will show you the principles.

Thanks Luc. I didn't know about operator overloading -- that's exactly what I need.

What about applying vb.net intellisense in a user editor?

Any ideas on that?!

Not sure I understand the question.

Inside Visual Studio Intellisense is at your service; it parses your project files and adds
class information to the system's .NET information and presents it while editing.

In a separate editor, you can do similar things; I have no idea some Intellisense component
from VS would be available to assist you in that. I trust big editors have it on their own,
you may (or may not!) want to have a look at Eclipse, the Java IDE started long ago by IBM.

What does 'the problem occur' mean ? What goes wrong ? Are you installing the .NET framework on the other machine ? Did you try to google your error message ?

Yes, I recommend you do some reading so you have a basic idea of what the framework you're using does, and how it works.

You need to change the values of the specific row, which means you need to grab the value from that one row, and change it. If you rebind then you will change them all.

Your view has properties for items, columns and rows. So, you change a specific value by accessing that row/column and changing it.

Hi All,
I'd like to build a video-phone, where the voice and video from my PC can be shared with some else and v.v. I'm not sure where to start. Can anyone recommend an article or other good starting place for this?

I'd like to use VB.NET or C#.NET.

Thanks!

Printing Problem [modified]

Hi,
I want to print a bill as follows: (Sorry it's in Dutch, but it doesn't matter for printing)
"www.uploadgeek.com/uploads456/0/factprev.jpg"
That means i want to print a logo in the upper-left corner, 5 lines of text in the upper-right corner, then print a horizontal line and above that line print "Factuur". Below that line i want to print 4 lines of text at the right AND the left.

Please help me out.

Thanks, Big Grin | :-D

Hi,

I don't know how you did this, but the URL is not visible in your post; it is visible
when I start a reply though, on top of the edit window I am typing in.

I haven't seen the JPG, uploadgeek seems extremely slow...

anyway, the normal way of doing print stuff is create a Control that somehow shows your
output on screen, then do the regular print operations to get that Control printed,
i.e. the OnPaint() method you create to display on screen will also be used when printing.
I tend to use a Panel, and paint all strings and images myself (with Graphics.DrawString
and Graphgics.DrawImage).

You can see a one-page printout example in my Sokoban article (it is C#, but exactly the
same stuff can be done in VB.NET).
