The program I write is in VB.NET. But examples can with c# are also accepted.
Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
I made a notepad using vb 2008 and I am facing a problem who I'd make the Statusbar.

' Variable And Const
Private Const MEM_RELEASE = &H8000
Private Const MEM_COMMIT = &H1000
Private Const PAGE_READWRITE = &H4
Private Const WM_USER = &H400&
Private Const WM_GETTEXT As Integer = &HD

View 3 RepliesI have a label inside an update panel which I wouldl ike to use as a status bar.Basically the user clicks a button which executes a main fucntion that performs a series of tasks. I'd like to inform the user as to the state of the function as it progresses e.g.:
Stage 1: Retrieving data...
Stage 2: Calculating values...
Stage 3: Printing values...
Stage 4: Done!
I've tried updating the updatepanel directly from the function but it only updates the panel at the end of function (stage 4) and shows "Done!" (which I understand is how it should work).I've been looking into timers and threads to try and update the panel separate to the main function?
I am trying to Send an Email with an attachment (using Gmail) but I keep getting errors like "Operation Timed out" or Failure Sending Email". It was working earlier today but I found out that i needed to add Using statement because the email was having a file open that had to be deleted after it was sent but afterwards it doesn't work.

Private Sub SendMailOneAttachment(ByVal un As String, ByVal pass As String, Optional ByVal smtp As String = "smtp.gmail.com")

I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
View 15 RepliesI define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)

Email.From = New MailAddress(Settings.txtFrom.Text)
Email.Body = "Email Body"

The error I get is: The parameter 'addresses' cannot be an empty string. Parameter name: addresses And it's pointing to the Email.To.Add() section.
I've been able to create and send an e-mail using System.net.mail. But it appears that the message isn't being sent until the application closes. This causes two major problems for me.1) When the user tries to send a second message, I get the following error: a generic error occurred in GDI+. I believe this is caused because I'm creating and sending a screen shot. If I take out the screen shot the error goes away. The screen shot is nice but not necessary. I can work around it, if I have to.
2) I am using the e-mail to provide notification that a process has been completed. The sender may continue to do other work while in the application -- including sending an e-mail to another recipient.
What do I need to do to get the e-mail to be sent before the application is closed?
I've got a client/server communicating nicely using TCP to send text strings and to parse and act upon the messages at either end, but now I want to be able to send small files. I thought it would be as simple as reading the contents of the file into a buffer and sending that buffer as if it was a message but obviously not. When I retrieve the message at the client end I get "System.Byte[]" so its given me the variable type and not the actual contents of the array I thought I'd passed in!
My Sending code is this :
Public Sub SendFile(ByVal Filename As String)
Dim sw As IO.StreamWriter
Dim fs As IO.FileStream
[code]....
(NB I did search for this within the forum and found some examples but they just didn't fit very well with the framework of what I'm doing, such as creating a 2nd tcp channel to handle file transfers?
