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.

Buy a book, take a class, or learn how to use Google. I know this is going to sound harsh, but we expect people here to at least have an understanding of the very basics of what they're trying to accomplish. We can't possibly be expected to teach you the basics.

Hi there,
how can I add any number of radio buttons to a panel in C# code , in other words : how can I add radio buttons during run time to a panel in C# application
Thanks in advance

You can use a RadioButtonList and add the items in the serverside code, you can also use its datasource property and dtabound method to bind the list from the database, or just use Items.Add if you want to hardcode the list.
<edit> sorry i assumed that you were using asp.net fogot i changed forums. there my be a similar control in winforms i cant remember, or you might be able to add them to the forms or panels control collection, but positioning them correctly would be difficult, it may be easier to have a fixed number and just show or hide them.

thanks for answering ,
but I did not find such control in windows form
and I need the number of the radio to be for example from the user , so I should create as many as the user needs
when I tryed to use Controls.Add of the panel , it added only one radio button,
should I change some of the properties of the panel ?
Thanks

each time you call Add it will only add one button you'd have to use a loop to add multiple, but then finding them in the form to do something with becomes slightly difficult but not impossible. or if you knew the maximum number of controls you could have them already there but just invisible then go through and make them visible for each case. I'm not sure how well the layout will work if you add them via a loop and the Controls.Add method, and you have the possibility of adding controls that the user cant see or interact with.

mmmmm, thanks for replying
the fact is: there is no max number of those radio buttons ,
also I am already using loop , but still I only see the first radio button in the run instead of all of them
any other ideas!
thanks again

If there's no max number, then you'll have to resize the form to fit all of the controls.. However Have you tried creating a new control in the code i.e. RadioButton rb = new Radiobutton(); then setting its x,y coordinates to something, they may be defaulting to 0,0 and just appearing on top of each other. you'll have to use those settings to make sure that they are all visible to the user and visible so that they can be clicked on. Also if you do this after the form has been shown they user may notice a delay and/or see the controls appearing and the form resizing, which isnt the best in terms of UI, some users may freak out a little bit.
