Well for starters you have an extra '}' at the end. In Visial Studio (or almost every good text editor) there is a way to match braces, brackets and parenthesis. Give it a shot; you'll find the culprit in no time.

You should do what I do. If I have a real stumper on my hands, I start writing a message here, but I ALWAYS go back and look a little harder at my code before posting the message. It doesn't always work out, but I have discovered quite a few "stupid programmer tricks" that saved me from having to ask a question.
BTW, your try block starts too late - it really should be around ANY code that can throw an exception.

Good Day,
IF File.WriteAllBytes and File.ReadAllBytes does not have the ability to "return" the progress of the operation, say writing a 1GB file, then what are my other options?
My major concern is to be able to extract the progress of the byte writing/reading since I am working with really large files.
Thanks!

Can't you read/write them in chunks of arbitrary size, for example 1mb per chunk?

Yes, that is what I'm hoping to achieve. The "older" way to write files.
But I need some example codes or a link perhaps.
Thank you.

You can use BinaryReader.Read[^] in a loop, starting with offset 0 until the end of the file is reached, increasing the offset with the chunk size in every loop step.
If you wish I can post an example later (unless you won't find one on google or someone else answers in the meantime), I have to leave right now.

Please do so if you have time. Thanks!

Hello,
Perhaps you can use timer and keep an eye on disk space being consumed...
Like:
1. Have a timer
//do what you want..
2. Get free space in hard-disk you are playing with big files
3. Play with files
in timer tick check free space again, you do know the size of the file right? use these two and check approximately how much work has been done.
HTH!

Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks.

Hi,
That approach won't work, unfortunately. I already tried a similar approach using FileSystemWatcher. The problem is that File.WriteAllBytes() will initially write the full file size. I do not know why.

Why not try out with System.IO.DriveInfo?

Alright, I'll try it and report back.

Hi, I've tried it and the outcome is also the same as using the FileSystemWatcher.

Take a look at the FileStream class. That's the basis of reading and writing files, that's what WriteAllBytes, ReadAllBytes and all the different reader and writer classes use to access files.

Hi Guffa,
My problem is that I don't know how to write a bytearray chunk by chunks.
Say I already have byte[] Data, and I want to write it 1024 bytes at a time.
Regards

Use a loop.
Example:
int pos = 0;
int left = data.Length;
while (left > 0) {
int len = Math.Min(left, 1024);
stream.Write(data, pos, len);
pos += len;
left -= len;
}

Exactly what I needed! Thank you!

Hi,
Hope this is the right place to ask, I have the following problem:
I have a .Net 2.0 Forms/C# solution in visual studio 2005, running on windows Vista Ultimate (both fully up to date with patches).
When I open up VS2005 and select the project from the VS Start page, weird stuff starts to happen: While loading the project, VS decides to spontaneously start up the application (without me having touched any buttons).
I can't stop the program once it's running from the IDE: shift-F5 and the debug menu don't work. But as soon as I close my app manually, Visual Studio sometimes crashes immediately.
This happens about a third of the times I open my Visual Studio project. But if it doesn't, there's always a chance of it happening at some random time while I'm happily coding about: My project will just start to run spontaneously: No compiling or anything, just running the version I last compiled.
I've had this VS installation for over a year now, never had any problems with it. The problem only seems to occur with one specific solution: I don't have it with any other solutions I made.
Any advice?

You have an exe maybe in your source control? I have never heard of this, so that is the best guess
|
|

|

Nope, no exe files in my solution. Haven't been able to even find someone with the same problem on the net and have been searching all day. This must be the weirdest problem I ever had.

That is weird indeed. Maybe something stuck in the addin manager? Maybe a rogue plugin?

I need to display content printed from a third party control in another third party PrintPreview control (SpreadsheetGear and Infragistics controls, by the way). The c# Printdocument only allows you to "draw" what is to be printed manually, by means of the Graphics interface. For my data that is contained in a spreadsheet and can therefor be anything at all, that is not a valid solution at all. Is there any way at all to rather "intercept" a PrintDocument from a print job, and then bind that to a PrintPreview control?

Learn a programming language, learn the associated libraries that go with the language and then create the application.
All of this should be relativly straight forward with books and online resources such as the MSDN, or you could even find someone to teach you.
