Function Can Only Happen In Specific Container?
Oct 21, 2011Strange problem: This code gives the appearance the I have 'Split' 1 button into 2 (B -> B(1) & B(2)) and then can 'Join' them back(B(1) & B(2) disappear and B returns). All this works fine, 'cept when I try to declare the only container where this can happen. The 'Control-S' part works as long as the lower portion is commented out, when I uncomment the lower portion 'Control-J' neither part works - the code skips down to the msgbox -
If e.Modifiers = Keys.Control AndAlso e.KeyCode = Keys.S Then
If DirectCast(sender, Button).Parent Is flp1 Then

System.AccessViolationException Happen Because Of Faulty RAM?
Sep 18, 2009I have a website that i've been working on for about a year now.Recently, it's started throwing System.AccessViolationException every now and then, in my dev machine, mostly, when I was away from the machine.I haven't changed anything on the server code in weeks, since I've been working 100% on the Javascript part, and this error started appearing recently.
Also, the code I'm doing is 100% managed. I'm not doing any interop, calling strange DLLs, nothing. It's pure VB.Net, so I don't see how I could be generating one of these myself.Now, I've been using this new machine for a couple of months, and it's not working 100% right. Every 2 or 3 days I'm getting a blue screen for example. I haven't had time to diagnose it properly, but I'm suspecting I may have a faulty RAM chip.

View 7 RepliesMake Loop To Make Certain Thing Happen About 10-30 Times Without Taking In Too Much Memory / CPU?
Oct 16, 2011A few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?
View 7 RepliesAssigning New Things To An Image?
May 1, 2010OK, Well I'm creating a "Card" creating app. The app will let you type in the name you want in the name field and then select a picture. But the problem is, is the saving. I want the card to be transparent like the original. The original is just a blank card. And theres a picturebox on the form that shows the original transparent image, and then a label over the name tag part of the original transparent image, and then another picturebox over the original pictures box for the picture, everything works for designing and it looks great after your done designing the card. But saving will not be transparent and it will not blend with the background.
How do I add onto the image and still keep the transparency of the original and then save it?
This is my code:
Label1.SendToBack()
PictureBox2.SendToBack()
Dim Card As New Bitmap(Panel1.Width, Panel1.Height)

C# - Generating Excel Through .Net Doing Odd Things?
Feb 4, 2010I have a rather odd thing happening with an Excel WorkSheet that I am creating through .Net.I load up an existing workbook
Dim _xlApp As New Excel.Application
Dim _xlWorkbook As Excel.WokBook = _xlApp.Workbooks.Open(_templateFileName)
set it to be visible before populating it (for debugging purposes)
_xlApp.Visible = True
I then go on to populate the existing template.
Private Sub GenerateOceanFreightGrid()
Dim columnCount As Integer = 4 ' _standardColumnCount
Dim columnInsertPosition As Integer = 5
[code]....
When i set a breakpoint on the "Private Sub Gen.." line, and step through the code line by line, it inserts a new column for each variable declared, so in this case it will insert two columns before it even hits the "If MyBooleanValue()..." line (I can watch it actually happen due to the Excel app being visible). However, if i dont set a breakpoint and just let the code run straight through this doesnt happen.There is no multi threading happening or anything else that i suspect would have any impact on the code.

Running Things In The Background?
Jul 20, 2010I have a class that wraps up a few methods (e.g. OpenPort, SendMessage etc.). Some of the methods accept a number of parameters and return a value (e.g. SendMessage accepts port and a string that is the message to be sent and returns true or false depending on whether the mesage was sent successfully or not). I create an instance of my class when my form loads and I call the various methods throughout the lifetime of the app.In my SendMessage method there is actually a few steps that involves a delay as I send commands to an instrument and wait for a response. I'm using the AutoResetEvent class to synchronize things. Whilst this works ok I've noted that the UI is unresponsive during the wait period.
Public Class MyClass
Private _receiveNow As AutoResetEvent
Public Function OpenPort(ByVal portName As String, _
