Visual Basic Discussion Boards

Sir/Madam,
Can I programically ascertain , the number of users who has accounts on my operation system , using the VB.net 2005 .
I can find out the user who is currently logged in .
By the following code.
System.Environment.Username
But I want to know the no of users who has account on the operation system.
Please help.
Thanks and Regards
Pankaj

::Example code here:
--------------------------------------------------------------------------------------------------------------
Private Function draw(ByVal g As Graphics) As Integer
Dim sf As New SizeF
g.MeasureString("hello world!", New Font("Arial", 9), sf)
Return sf.Width
End Function

Private Sub pd_PrintPage(ByVal sender As System.Object, ByVal e As
System.Drawing.Printing.PrintPageEventArgs) Handles pd.PrintPage
draw(e.Graphics)
End Sub

Private Sub mySub()
Dim g As Graphics
' What should I do here with g in order to get equal results
from draw() functions
' in pd_PrintPage() and in mySub()?
draw(g)
End Sub

Tell me please if it is possible.

mySub should call Invalidate() to force a paint event. Although, I see that neither of your other blocks of code is a paint event. What are you trying to do ?

how to create 600dpi graphics

Oh, OK. You can use a scale transform to make everything you draw, bigger. There may also be a DPI setting, but I'm not sure what that would achieve.

Would you care to explain the problem or should we just guess?

Actually I am very surprised to hear this from an MVP, the thing is simple i need to dock a window form right above the task bar,

Now wht further explaning do you want?

Thank you!

"Mess with the Best, Die like the rest"

You'd be surprise how often a question shows up on the boards that can be answered with "Permission Granted". "Great! You want to do something, now what's the problem?" If you would have asked "what are the steps involved in...", that would have clarified where you were stuck - in your case, step 1.

I think you're referring to a Desktop Toolbar, something like this example[^].

Can you please give me a regular expression in c# to remove single line comments from a string and please kindly help me its urgent

Criteria
a. // text --- Should be removed
b. file:///text.txt -- should be retained
c }//abc -- hear //abc should be removed

Thanks in Advance

Thanks and Regards
Irsh

read each line as well as each character
and thus the comment line will get eliminated.

i want to expire the program after 30 day , how i can do that , and don't affect with windows calender if user set back the time

There are several approaches for this. Whenever user installs your application, you check user's internet connection. If he/she is connected to internet, you can check date and time according to user's location via a time zone in web and save this values as encrypted information somewhere under your application's directory. Therefore whenever user runs your application, decrypt this values and calculate remaining date or time.

Another approach is to calculate remaining time not date. Therefore, Whenever user installs the application, record time (HH:MM:SS). Accumulate time and convert it to date (if you want to) each time user runs your application.

I hope that helps for a bit. WTF | :WTF:

What a curious mind needs to discover knowledge is noting else than a pin-hole.

greate , may you help me with the code for the second approch , calculate the remaining time ..

Hi,

I would like to know how can I debug through multiple application at a time from a piece of code.
Like to perform "attach to process (Ctrl+Alt+P)" through code.
Any response in heartily welcome.

Thanks in advance
Regards
Parag

Are you writting a debugger? What are you trying to do with this "attached process"??

A. Title:
Pig-Latin

B. Application:
Control Structures
Procedures
Arrays
Object-Oriented

C. Program Specification:
Project Name: MacProb3
Project Type: Windows Application

D. Requirement Description:

This English to Pig Latin translation program performs a (near-) perfect
translation of any English text to Pig Latin. Words, phrases, sentences,
paragraphs and more.

Basically, the Pig Latin system used here works as follows:
* Words that start with a vowel (A, E, I, O, U) simply have "WAY"
appended to the end of the word.
* Words that start with a consonant have all consonant letters up to
the first vowel moved to the end of the word (as opposed to just the
first consonant letter), and "AY" is appended. ('Y' is counted as a
vowel in this context)

The algorithm incorporates the following features and special case functionality:

* Ensures proper capitalization
* Correct upper case and lower case formatting
* Correctly translates "qu" (e.g., ietquay instead of uietqay)
* Hyphenated words are treated as two words
* Words may consist of alphabetic characters only (A-Z and a-z)
* All punctuation, numerals, symbols and whitespace are not modified

Implement the conversion process in a class named CPigLatin with the following
basic structure (you may include other properties/methods if you want):

Properties:
- EnglishText
- PigLatinText

Method:
- Convert

Write a complete Visual Basic .NET program to translate english words
to pig-latin words. Use the CPigLatin class in a Form that accepts
long texts for english words. The Form should include a Convert button
that invokes the Convert method of the CPigLatin class and then displays
the pig-latin words in a textbox.

You may use any string manipulation functions available in Visual Basic .NET.

E. Sample:

English format text:

Enter the English text here that you want translated into
Pig Latin. This is accomplished via this HTML document and
accompanying JavaScript program. Note that hyphenated words
are treated as two words. Words may consist of alphabetic
characters only (A-Z and a-z). All punctuation, numerals,
symbols and whitespace are not modified.

Sounds like a really fun assignment.

My advice is free, and you may get what you paid for.

i dont get it..

Hi,

Sorry to be teasing you, but as Jonathan said, please do your homework yourself. Now Christian already pointed you in the right direction by advising you what to read up on. Your reply was, that you knew that bit, but don't know how to loop it.

Your original message only stated the assignment your teacher gave you, but you didn't describe any problem. As a matter of principal, everybody here is willing to help you out when you don't know something, but nobody is going to hand you ready made solutions.

In other words, if you want help, ask a question, or post the code you are having trouble with, or describe in a little more detail what it is that you don't know how to do. That way you don't get people like me brushing you off, and more importantly, you don't waste the valuable time of people like Chris, who now gave you advise that you apparently didn't need.

If you know what exactly it is that you need help with (loops), post that, and not only general information, that suggests that you want someone else to do your homework for you.

Now did you figure out a general structure for your app? Are loops the only thing you are having trouble with? Didn't your teacher already teach you all you need to know to do this assignment, i.e. is getting information on how to do certain bits of the app part of the assignment?

Johan

My advice is free, and you may get what you paid for.

OK, what you need to do, is read up on the string class, and the substring method. If you still can't work it out, or even make a start, ask your teacher for help.
