I want to be able to take snapshots of the desktop periodically(about 1 every 300 ms) then be able to view them live through a web browser.
Here is what I already have:
I already have a form which takes the snapshots, overwrites a file called 1.jpg with the image. I also already have an http server running which succesfully serves up html documents.[code]...

but if the email has attachment picture(NOT AN EMBEDDED PICTURE) then the Browser automatically display that image to the center of the browser for example the last line of the html code is <CENTER><IMG SRC="CID:{A4BE96B0-6195-4D93- 45E-97D4B1CA3539}/nature2.jpg"></CENTER> but actually the email dose not has this picture as embedded but is only an attachment ,and the browser is displaying it.
is there any way which i can easily disable that functionality or i should modified the code and replace that string with nothing. ?

I found that the overlay function was working fine. However, it seems that if I use the overlay function while reading an image from a stream, that it would enlarge the picture before overlaying it.
ie:
overlay = New Bitmap(stream)
g.DrawImage(overlay, 0, 0)
Seems to enlarge the image before overlaying it, whereas this:
overlay = New Bitmap(My.Resources.Pic)
g.DrawImage(overlay, 0, 0)
Seems to overlay the image fine.
What could be the reason for this?
I am new to .NET from VB6. So I do not have any background with streams, however the concept seems straight forward. I am trying to populate a listbox using the ADD method with the data originating in a text file. Using a stream reader I am aquiring the data (I can prove that the data is there at every itteration using the debugging tools). However, it doesn't make it into the listbox. I have other data appear withn the listbox in a couple of different ways just to prove that there is nothing wrong with the way the listbox is setup or coded. The listbox is a single instance item on a form, all setup is done through the properties window.

I experimenting with the Twitter streaming api, an am trying to open a stream for a user to consume events as they happen. I using a standard set of classes for making REST api calls to twitter. When using url... in a "GET" call the response stream never ends.I'm opening a StreamReader and reading the response as I would with any other REST call to Twitter. This is probably obvious to others, but how do I "consume" this stream... Is there a way to read the StreamReader as it's reading (meaning before it closes)? or maybe there a different method I can user to consume this stream.... again, I apologize if this seams to be elementary to some, but I can't figure it out at the moment. Here is the original source I started troubleshooting this with.This method was fabricated from a set of C# Classes I found in a forum on LinkedIn. At the line that reads "responseData = responseReader.ReadToEnd()" the method starts to "drink" the stream... but do so like a bottomless cup... reading this stream of data in real time before it closes (which is essentially until I stop debugging or kill the process) is the question I'm tackling.[code]
This write the opened twitter stream to the file, and every time I Tweet, Retweet, Delete, Direct Message... and so on.The file grows with a JSON object appended to the text. I used the Do While 0 < 1 for testing here, because I just wanted to see it working. I see on MSDN StreamReader Constructor Description that the New constructor is supposed to accept a Boolean value for "leaveOpen", but no such argument allowed when I try to add this to the constructor.Does anyone have a good example of how to do this with forcing and infinite loop or just a better approach than this... I would like to simply read new updates sent each time from Twitter, and address them accordingly? There is obviously a way, I'm just new to the concept of consuming a stream like this with out it being closed.

Apparently, there is some kind of "bug" or "feature" in 64-bit Windows that prohibits a 32-bit app from "seeing" certain icons. Testing this is simple:Create a basic Windows Form app on a 64-bit machine.In the Project Properties, go to Compile > Advanced Compile Options > Target CPU. Set Target CPU to "x86".Add a button to your app that triggers an OpenFileDialog. Run the app and click the button to open the OpenFileDialog.Browse to: C:UsersDefaultAppDataRoamingMicrosoftWindowsStart MenuProgramsMaintenance
You should see the "Backup and Restore" shortcut, but its icon will be a blank white sheet. (If you don't see it there, it might be in C:Users[MyUser]AppDataetcetcetcMaintenance).
Now, close your app... go back to Project Properties > Compile > Advanced Compile Options > Target CPU and set Target CPU back to "AnyCPU" (this will cause it to run as 64-bit).Run the app and browse to the same folder. Now "Backup and Restore"s icon will be visible.This happens on all 32-bit apps. I tried it in Firefox (using "Open File...") and it can't see that icon (and many others) either. as a result of this behavior, when I try to extract icons from files when running under 32-bit, it produces an error. If I run the same code under 64-bit, it works just fine. running my app as 64-bit isn't an option. I'd literally quit programming if I weren't able to use Edit-and-Continue, and for some brilliant reason, 64-bit apps can't Edit-and-Continue, so I make them all in 32-bit).
I have a system which needs to be secure which streams relatively large documents from a webservice to a proxy (Web site) whch then grabs the stream and pushes this to the client. This works but there are some issues where it seems the response is not being pushed until the entire stream is complete? whether this is the case Im not sure have run charles and until it completes it is "Waiting for response".
The documents are currently PDF but it needs to handle many other types for the future. The octet stream etc is mostly testing related, how to get the Dialog to show - saying save as? for the large files the little ones don't matter to much but the big ones leave a big waiting period with no response.

How do you create an array for images, specifically to develop a slot machine game so-to-speak. Because our class is using a really, really old version of Visual Basic (that is, VB 4.0...ick), I decided to move myself up in the ranks and play alongside and learn the newer software.I've mentioned arrays before if you recognize my screen name, but situations caused me to bump up again to 2010, so now I need some help reacquainting myself with the software.
View 3 RepliesPart of the app I am writing allows users to create an encrypted, password-protected output file that they can email safely to a central store. I can't have the users choose their own password for the encryption as the central store needs to access the contents of all the output files emailed to it. So there is one password that gets set within my vb app.I am worried that security will be compromised if the vb executable is somehow deconstructed? Is it possible to read the contents of an exe file (and thus find out the password)?
View 3 RepliesI am working on some sort of client + project management system. Each client can have many projects, many projects can have many staff. The Link (Junction) table allows for many staff members to be linked to the projects. I have attached the relationships which have been put together in Access 2007. In order to display the data in my VB forms, I am making use of OleDb, by having a OleDbDataAdapter and DataSet. I am using SQL queries to select, insert etc data from the original database tables.
My issue; I can't work out the best way to link the data together so it can be viewed on one form. So once I access Client 1, I can see the projects they have with us, and then within that, all the staff they have working on that project.
