View 2 RepliesI'm trying to send an image over TCP... I believe I'm sending the image correctly, but how do I receive the image?
Here's my code in sending the image (To shorten the code, I didn't show how the image is created).
Code:
Dim tmpImage As System.Drawing.Bitmap
'client is the connected Net.Sockets.TcpClient
tmpImage.Save(client.GetStream(), System.Drawing.Imaging.ImageFormat.Bmp)

I have googled this and found older vb codes that do not work in 2010. The user, in this case a "cheater/hacker" isn't suppose to be aware of a running program that checks memory and some other information. I have succesfully read the values of certain memory adresses in my program, now I need to send those values to another program secretly opened as a date and time sort of thing. The program checks for malicius attempts to edit memory or edit information inside the software and it automaticly deletes all the data or does a "ban" if somebody attempts to freeze memory and edit it.
So the problem is how to send this data to program out of focus, I can send strings with appactivate but it will open my security program to screen everytime memory changes witch is almost every milisecond so it's almost useless cause it keeps switching focus. I need something to send it out of focus, so my question is;
I make a hook between my program and my security program, send messages/strings out of focus or in tray?Also it would be good if I could make my program "invisible" so he can't be seen even in tray and still keep working.

View 39 RepliesI'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.

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)

I am toiling with the best way of doing this. So far, I am not having much luck. I have used arrays quite successfully in Java, but I am not sure that this is the best way to go here. I would have to get how many lines there are and read each line. Make the changes, and then go on to the next line. I think scanning the document line by line using a loop is the best way. However, I am not sure.
