ive been trying to use System.Security.Cryptography to encrypt and decrypt a file but its not working for me
this code
Private Sub EncryptFile(ByVal sInputFilename As String, ByVal sOutputFilename As String, ByVal sKey As String)
Dim fsInput As New FileStream(sInputFilename, FileMode.Open, FileAccess.Read)
Dim fsEncrypted As New FileStream(sOutputFilename, FileMode.Create, FileAccess.Write)
Dim DES As New DESCryptoServiceProvider()

called with
DecryptFile(OpenFileDialog1.FileName, SaveFileDialog1.FileName, "12345678")[/CODE]
outputs a file that is almost 2x as large as the source file that was encrypted.
What I am doing is making a Media Player, but I am making it to be some sort like BS Player.
The Video part of the player is on its own with no border and then there is going to be a separate Form for the controls. (I might need help with that later) But the first thing that I have to do is make the window movable and re-sizable by dragging the Media Player (WMP). WMP is taking up the whole screen of the Form so there is no where to click on the original Form. If possible, I would like it to show contents while dragging, ignoring the Windows Appearance and Performance. If that can't be done or is to much work, I will settle for just the border of the Form being showed while moved.
For re-sizing, the media player has to stay the same size as the form, but it also has to stay the same Ratio of the video. So as long as I can specify the current height and width of the window and also get then get the width while the window is being re-sized, I can get the height that the window needs to be by using this formula.
Window.y / Window.x * Sized Window.x = New Window.y .
I know that may sound complicated or maybe I am making it harder then it actually is, this is just how I know how to do it. I will explain what each variable in the Formula means.
Window.y is the current height of the window
Window.x is the current width of the window
Sized Window.x is the width of the window while it is being re-sized
New Window.y is the final height for the new size of the window
Which of the MediaPlayer events is related to "FileEnd" (when the playing file reaches to its end)?
I tried "EndOfStream" event, but it didn't work.
I want a rich text box to display public variables like (pizza toppings links etc that have been selected in other forms) these variables have declare in a module. But I want the rich text box to display these variables as soon as the screen loads ( a on form load event) if you know what I mean.

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
How can I load a form and allow it to run it's code in the form load but keep it not visible. I want it to do what it needs to but but not display.
View 3 RepliesI just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

This has always worked until I started using W7.

View 1 RepliesI am trying to write some code that will allow me to dynamically load DLLs into my application, depending on an application setting.
