Copy Left Half Of A Picture And Paste It Over The Right Half Of The Picture?
Feb 28, 2010
how to copy the left half of an image, in my case its the let half of a .jpg of a whale, and "paste" it over the right half of the image. Any help would be great, here is some code that might have something to do with it, i would prefer that i could get an answer that accomplishes this by modifying this code but if not that's cool. picture should go from looking like [] to [[
Dim mb, rb As Bitmap
Dim x, y As Integer
Dim r, g, b As Integer

What my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:

Imports System.Windows.Forms
Imports System.IO

I'm trying to copy a picture from one location and paste it into another location however VB throws out the following error
Exception from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED)
both locations are on my local computer. So not sure what is causing the problem.
Here's the code

Welp, I got half way there, I can convert and add 6 hours to the text in the textbox for CET_Hours.Text. The trouble is, what about when the CET part of the program is supposed to say that it's the next day...?
Public Class Form1
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If DateAndTime.Now.Hour > 11 Then[code]....
Like I said up top, it was easy to figure out how to add an additional 6 to the text in the textbox for CET_Hr.Text, and even display if it's AM or PM, ... So okay, that's that, now when it goes over 12PM and goes into Am, meaning, when I'm adding 6 to the text, If I didn't correct it, it would say... Say for example if it were 11PM now, EST, and I added 6, it would read, CET_ Hr.Text = 16 right, ... So how do I tell the program or the text in the textbox, that it't the next day... or better yet, when we get to the end of this month, 12.31.2009, and it becomes 01.01.2010 in CET, how do I do that, because I'm just so freakin perplexed about that it's crazy... Should I just give up, and just have a clock that tells me that it's 6 more hours then the bottom text boxes...?

I have a textfile with timestamps and the amount of minutes my machine has run.
To keep the size of the file in check, I would like to delete the first half of the text file, once the textfile exceeds 1 MB... I have a check in place to determine the file size.
What is the best way to go about deleting the first half of my textfile log?
Do you recommend storing the second half in a temp file, and transfering it to the original log?
Is there a simple way to remove the first few lines of a textfile?

I have two pictureboxes with images in them inside a panel. The two pictureboxes have the background color transparent. One half of one of the picturebox is over the other and that half gets the panel backgroundcolor. How can I make the pictureboxes to not get that behavior.

I'm reusing some code to paste parts of an image into a picture box. It works in the original programme, but not in new one.I have 'picMap.Image = New Bitmap(picMap.Width, picMap.Height)' in the form load subroutine. When an image is clicked, it send a message to this subroutine
Sub Draw(ByVal X As Integer, ByVal Y As Integer, ByVal S As Integer)
Dim g As Graphics
Dim Img As New System.Drawing.Bitmap(picNotes.Image)
Dim src_rect As New Rectangle(S * 44, 0, 44, 44)
Dim dst_rect As New Rectangle(X * 44, Y * 44, 44, 44)

I need to display the first c.200 characters of a longer string, for the homepage of a news website. I am using VB.NET. Obviously, cutting exactly 200 chars quite often cuts a word in half, e.g.: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at regu" I need a function that will produce: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at" I can then add "... [More]" or whatever to the end of this string and voila! Is there any way of using regular expressions (regex), substr or something similar to produce this output?

web app that has been created using VB.NET, nothing major, just a normal site. His original programmer couldn't continue so he wants me to finish it. Problem is I don't program using VB.NET nor have I any intention of learning it for a project this small. Usually I would run from something like this but I need the cash.Should I take the project and continue it using C# or just leave it. Has anyone had a similar experience and how did it turn out.

I want to display the first and last characters of any given string entered into a textbox. The strings can be of any length as the user wants (as long as it is one word) I would like to be able to do something like this... "william = will and iam" or "Celtic = Cel and tic"I understand I would have to split or divide the string. How would I go about doing this?

I created a program that has 11 threads running simultaneously.Each thread runs a stopwatch and measures the amount of time that passes between the Start and Stop.There is no code between the start and stop, so most often, the result is 0 milliseconds.I noticed that INITIALLY, after a few minutes, the program would slow and the output to the RichTextBox would become disjointed.So, every two minutes, I have a timer execute and end the threads and restart them all.This seemed to help, however, after about an hour and a half, the program becomes more sluggish, evident in the stopwatches recording more instances over 0 milliseconds.Does this have to do with 'garbage collection' and is that even possible in VB .NET (I thought C only had that), or perhaps memory management?

I have a situation that has puzzled me for weeks. I am running logic that does a bit of back and forth to and from the database for each time it is executed (about 20 times). The problem is that the same code works about half of the time. What could possibly be the reason for the difference in execution performance and how can I better shore that this problem is checked?
