.net - GDI+ Change Line SmoothingMode?
Feb 17, 2010
Is it possible to change PowerPacks.LineShape smoothingMode?I tried to use this code(a class that inherits LineShape):
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
Dim g As Graphics = e.Graphics
' no difference when changing the SmoothingMode '
g.SmoothingMode = SmoothingMode.AntiAlias
[code]....
Result (don't take in consideration labels and circles):apparently smoothing mode is not taken inconsideration...

A string contains the following lines:
:61: C123456,1235AC
:81: hekljkjkjskdjfjafja;f
Bet. kenmerk 123456
I have code for regex.replace which is working.
The problem is that I only want to change the line: Bet. kenmerk 123456.
Not the lines which starts with :61: and :81:.

I have a text file with the format:
(title,price,id#)
CD1,11.00,111111
CD2,12.00,222222
CD3,13.00,333333
[Code]....
What is the best way to go change the price of the appropriate CD if I'm given the id# and new price?
I'm sure it has something do to with getting the line and splitting it, but I'm not sure how I edit just one line and not mess up the whole file.

Retrieving strings from a serial port with ReadLine works fine as long as the line ends with a linefeed chr$(10).However if no more strings are available to be read, Do Loop or For Next hang up waiting for the linefeed which never occurs.I believe using chr$(0) in place of linefeed would still work with strings ending with a linefeed..Just that the linefeed would be output.I have the complete MSDN Library.

I've got a listbox in visual basic 2008 with lines that look like:
item 0; item 1; item 2; item 3
How can I select that line and change within that line the value of e.g. item 3? (by default it's set to 0 and should be set to a value > 0 when entered by the user.
After that I need to calculate the total price based on the price in item 2 and the new value of item 3 (being >0)

Recently, I just helping my friend for developing game private server, in Game Client there are 3 application is needed, its is a patcher, launcher, and main exe, my friend use open source (C++ language) application for the patcher, the patcher is work nicely, and the launcher is program that launch main exe, its using launcher because main exe is need some argument to run, the launcher is created by me.The problem is the user can be run game directly without opening the patcher, so I want to change default command line (usually "0" / "1") in launcher to 3, and I have the trap if user open directly the launcher
If My.Application.CommandLineArgs.Item(0) = "3" Then
MsgBox("Please Run Patcher to proceed the game!")
End

I'm using Visual basic 2010.net with service pack 4.0. I'm using the built in chart control to generate a line graph. I have a series plotted on the fastline graph. Is there a way of accessing the weight/thickness/boldness of the line and changing it? I was able ton change the colour and I could even change the point size on the fastpoint graph.
Code:
Private Sub DisplayGraph_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am currently drawing a line with Graphics. Drawline. Once this is drawn, under certain circumstances I want to change the colour of it. When the line is drawn, does it become an object that I can then refer, or do I simply draw a new line over the original in a different colour

I have a problem with a mutli-line text boxes, ListBoxes and DataGridView controls which contains a vertical scroll bar. The scroll bar is too small for anyone with big fingers. Is there any way to make that scroll bar wider so that it's more "finger friendly"?

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
