.net - Silverlight - Sending Variables Between The Frame?
Dec 27, 2009
I have one main page in my Silverlight project. I have two frame inside this page. The one called Contents and the other called Footer. What I wonder is, how can I change the variables in the content in the Content of whether that's a click event in the Footer?

The program I write is in VB.NET. But examples can with c# are also accepted.
I am creating 2 forms (btw these is test script just to learn and understand it.) 1 form is where the info comes from like the Username and other stuff the second form is where the data will be shown.. i got it to transfer the data to second form but what im having problem with is well more of a question is how can i send the variable to a statusbar?
I have a LOB app written in VB.NET with a WinForms front-end and SQL back-end. After many months weighing up how to get onto the Web, I decided last month to use Silverlight 2. Now, Silverlight 3 Beta is out, but there is no end-user runtime.
Does anyone know when the runtime will be available for deployment of SL 3 apps onto client sites? My dev timeline is about 3 months: should I persist with SL 2 and then u/g to SL3, or jump straight in to SL3?
how does this function works. How does it copy the frame? HDC BiBlt???
ublic Function copyFrame(ByVal src As PictureBox, ByVal rect As RectangleF) As Bitmap If isRunning Then Dim srcPic As Graphics = src.CreateGraphics[code].....
the above function is called from the below command which is in a timer event. mycam is a class including the copy frame function.
bm2 = myCam.copyFrame(PictureBox1, New RectangleF(0, 0, PictureBox1.Width, PictureBox1.Height))
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.
Here's what I have (Portion of it): Private Sub SendMailOneAttachment(ByVal un As String, ByVal pass As String, Optional ByVal smtp As String = "smtp.gmail.com") Using oAttach As Net.Mail.Attachment = New Net.Mail.Attachment((Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "\" & My.Computer.Name & "_" & fName & " .zip")) Dim client As SmtpClient = New SmtpClient(smtp) [Code] .....
The ports are correct I believe, no firewall up on my PC...
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 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]
I 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.)
Does the memory used in declaring variables are reclaimed by the OS when these variables go out of scope?Does the memory used be released by setting thier value to nothing? if not, then how can I force the garbage collector to run or excecute at a certain/desired time..How about in Windows Forms..How can we make sure that the memory used in initializing and showing forms be released if those forms were closed?
Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.
I'm new in .NET programming.I have a class Form1 that includes Button1_Click event.Button1_Click creates a multiple Text Boxies at run time)Here is the class:

I have a personal project to complete and one of the smaller aspects is to capture about 10-20 seconds of video or a screenshot (bitmap,jpg, etc)from a DVD. This is made even more complicated by the fact that the video files may be .VOB, .AVI or .MPG and using numerous codecs (DivX, Xvid, etc).
I have searched on google and the tutorials here, but nothing seems to fit.
Does anyone have some "simple" references, URL's, blogs, code examples that would help with my quest? (My policy is not the KISS principal, but the KISFSP ... "Keep It Simple For Stupid People")

I am writing code to automate internet explorer. I have successfully done it for a few sites, essentially I need to be able to access the html, and elements such as input boxes to automatically fill out forms, and pull back the results. But for the current project the website has a framset and frames, I was wondering if there is a way to get access to the html and elements within the frame.
I am using Interop.SHDocVw to control internet explorer. I have been trying some code similar to the following, but after I get the frame I need and the documentElement off of it, I can't get the actual html inside the frame. I can get the outer page/framset html, but whenever I try to get inside the frame is comes up as Nothing. I was thinking it may have to do with IE frame security

[code] the part way at the end where it uses .elements(mySearchInput).Value = "bob" I get a compile error it says object variable not set? my guess is this text box is inside a frame called "mainframe" so how would I access an element inside of a web frame? it works fine on another site without frames?

i would like to create a fixed size frame for user photos uploaded. I've tought: i, can create a fixed sized image (200 width x 600 height for example), with my personal frame (top, left, bottom, right element graphics) , and in the center a transparency.
Ok, but i don't know how to merge the photo into the frame and save the new photo format.
