in my application I want to try delete an image file.. but at every attempt I get an
[System.IO.IOException] {"The process cannot access the file '..\\addAll.png' because it is being used by another process."}
I am sure that this file is not in use because I just dispose the Image object using this file with :
((PictureBox)flowLayoutPanelThumbs.Controls[0]).Image.Dispose();
flowLayoutPanelThumbs.Controls.RemoveAt(1)İ
1-Why occurs this cannot access bla bla bla error and how can I avoid this?
2-How can I find the process using this file
I will REALLY appreciate any help..
thanks and best regards

Use this tool: Process Explorer [^] to find which process is holding the handle to the mentioned file.

As suhredayan suggested, first check if some other process is holding open a handle to the file. If it's your process, how are you creating the Image object? I vaguely remember there being a bug in the framework that caused this problem if the Image instance is created using Image.FromFile. If you're using Image.FromFile, you could try Image.FromStream instead.

If you load an image yourself, then the file handle stays open until you call dispose. If you've called dispose, you should be able to save it. The answer often is if you use FromFile, to make a copy, keep the copy and dispose of the original right away.

Thanks for the answers.. As you guessed the FileHandle stays open so I taked a copy and Dispose the orignal one..
rule 1 : always use "using(.....){ }" when you are working with object that needs to be closed by hand 
Thanks a lot..

I'll try to be brief...
Problem:
Using standard (de)serialization I'm saving the contents of a multiline textbox into a few different string variables (depending on which option the user has selected), which are then being saved into an XML document.
Upon reading the values from the XML files and displaying them into the textbox the actual linebreaks are being replaced by a square (which is actually char 13). This is making no sense to me. The textboxes are set to multiline, and if I use a rich textbox control instead of a standard textbox control it works fine.
If I take the square character and paste it into notepad or the VS IDE it creates an actual line break.
Why is this happening and how can I fix it? I'm stumped.

In the string being displayed, replace \n with \r\n and it should work as you expect (or it might be \n\r I can't remember which!)
|

Some systems use a single character (10) as line break, while DOS/Windows uses two characters (13, 10).
You can fix any "funky" line breaks with:
theString = Regex.Replace(theString, @"\r?\n", Environment.NewLine);
This code works regardless of the type of linebreak the current system is using, and it doesn't mess up line breaks in the string that already are correct.

Made a correction about what characters are used, and changed the regular expression pattern accordingly.

b { font-weight: normal; }

Thanks. This didn't work directly, but after making it search for just "\n" and replace it with an Env.NewLine that did work.
Strange...
|
|
|
|
|
Right. The square characters that you have is not the carrage return (char 13), but line feed (char 10). I have corrected the code that I posted earlier.

b { font-weight: normal; }

Hi all,
I have a program that generates some HTML and then needs to automatically print it. This automatic printing occurs within a separate thread (timer) and for the life of me, I just can't get it working.
After a couple of days Googling around, I found a couple of things:
1) Attempting to do it calling IE (or the equivalent DLLs) isn't an option since it'll always pop up a print dialog box and there's nothing that can be done about that.
2) webBrowser1.Print() should work, but doesn't. It doesn't call an exception, it doesn't have any problems, but it also doesn't print. I'm assuming it's related to the fact that this is all in a separate thread from the timer.
3) If I attempt to be "messy" and just call a complete new thread that creates the webbrowser object, loads the HTML and print it, it gives an exception complaining it's not STA, even though I did set it that way.
So basically, I'm fairly stuck at this point. Here's the code I've tried so far minus the messy one, since that's definitely barking up the wrong tree I think. (note that the html is both in my webbrowser object or in the file - I'd love to not have to use the webbrowser object if I can get away with it)

To clarify further, this code:
YttriumOxide wrote: /* //This doesn't work - maybe because of the thread?
*
* webBrowser1.Navigate(szTempFolder + @"\Temp\Body.html");
* webBrowser1.Print();
*/
DOES succesfully do the webBrowser1.Navigate, but NOT the webBrowser1.Print - which is extremely confusing in my books... Why does Navigate work inside a seperate thread, but not Print?

Hello all,
I wonder if any of you have found/written a free Ribbon Control (the office 2007 style)?
I found some ribbon controls while googling but none of them are free (not even for non-commercial use).

I have a c# exe that must tranfere files from one server to another. Well it works perfectly when I am logged on remotely to the server but if I am not logged on it give an error saying it counl not find the destination drive.
How can I make it to run while I am not logged on?
|
|
|
|
|
If you are referring to the remote system's file system using a mapped drive then don't. Refer to it using a UNC path name.
|
|
|
|
|
Could you please explain further. I am not an expert in C#(still learning).
|
|
|
|
|
Colin is suggesting you directly use the UNC[^] notation, instead of mapping a drive to that location. You typically would have used the UNC path to setup the mapping in the first place.

can i get some unique value when I will press the backspace in the following event
private void richTextBox1_TextChanged(object sender, System.EventArgs e)
|
|
|
|
|
Try it by selecting the keypressed property for the textbox then checking when backspace is pressed. You KeyPreview should also be true i think.
e.KeyCode = BackSpace
or Back or something like that.
|
|
|
|
|
Only on TextChanged event not in key press
|
|
|
|
|
No.
You get what the event's name is indicating: The Text property has changed, nothing more, nothing less.
For example, if your cursor is at the beginning of the text, pressing Backspace will not modify the text, so no TextChanged event will occur.
To find out how the text has changed you'll have to save the previous version of the text and compare it with the new value.

Why do you need to create the connections tring at setup time?
You can create a custom action in your install package to write the connection string.
