I have an embedded DLL in my app and I need to write it to the filesystem at runtime. I have this so far:
Dim _assembly As Assembly = Assembly.GetExecutingAssembly()
Dim _rawstream As Stream = _assembly.GetManifestResourceStream("MyFile.dll")
I just need to write _rawstream to a file now.
EDIT: This has to be .NET Framework 2 and CopyTo does not exist
Just starting up on VB 2008 Express (.NET). Trying to write to and read from a file. It runs without errors, but the messagebox only shows the 'OK' button, not the contents of the file as I want. I thought that maybe I have to rewind the file before reading, but AFAICS there is no 'StreamRead.Rewind' or Reset or something.

View 6 RepliesI have a small problem with this code. I am adding information to my listview from multiple textboxes. As I add the info I automatically update a text file with the code shown below. The problem I have is When I add my first row the code will not write the data back to the text file, however if I add a second row the code is quite happy to write both rows of data back to the text file. I cannot for the life of me see what is wrong.

I am trying to return a javascript function using response.write in an aspx page. The problem is that the function i am returning has lots of quotes and they are conflicting with the repsonse.write syntax. Here is a sample code:
Response.Write(" If hello.StartsWith("H", StringComparison.InvariantCultureIgnoreCase) OrElse hello.StartsWith("W", System.StringComparison.InvariantCultureIgnoreCase) Then")
This is giving me a problem as the quotes inside are cutting off the response early. Is there a better way to do this?

This app is trying to send messages to a client listening on the port. The client's logs show that their port is being opened and closed, but no data coming in. Is there a bug or something missing in the following code, like perhaps stream.flush or stream.endwrite or a thread.sleep(0) line, that could cause this? The puzzling thing is, WireShark on the client computer does show the message my app is sending coming into the listening port.

I use a custom tool to translate a flat text to xml text. I then create the file, with over-write set to True. When I try to write the text to the file, I get the error. The error says "Error: Invalid procedure call or argument", "System: Access is denied." It seems like the Create command is holding the file locked, so the Write command fails.
Running in VbsEdit IDE, I can see it fail. If I copy the text which is trying to be written, and paste it into UltraEdit, then attempt to save the file there, I get the same error This is expected, because the VBScript execution is holding the file locked. It should NOT be holding it locked for the script itself, right?[code]...
Im trying to write to a file I created and place "Unregistered" in it. Thought it would be a simple task but keep getting an error. Its happening when I try and open the file to write. This is the error: Access to the path 'G:\Projects\Project\pbss\bin\Debug\5\pbssv\Data.DB' is denied.
Ive tried adding the file attributes to read-write and still get the same. Most of the code ive looked at via a google search points to the same as ive got for the Added default value area. Im not sure if there is a conflict between the 2 different ways im accessing the file when creating and writing too? [Code]

I am getting an intermittent "System.Web.HttpException: Request timed out." error when my code hits the line response.write():

Response.write(sSetVal)
Note that Response.BufferOutput = false is set when the page first starts executing (well before the above code executes).The code is used to update a progress message while other threads execute long-running processes. One thread runs continuously and checks the status of the other threads. As the other threads finish, this thread outputs updated status messages to the end user. I realise that this could (should) be recoded using ajax, but it is a legacy app and that is not an option at the moment.
This code is run 10,000+ times a day, and the error only occurs about 5 times - so I suspect the response object is being blocked by other threads when the website gets busy. However, I don't know which performance counters to check in the performance monitor. Or is this problem caused by something else? I am using IIS 6, asp.net v2 and vb.net?
