I am writing an simple application that will delete a file/directory. The application recives the target file as an argument. I have also put a shortcut in the W Explorer contextual menu, via Shell registry subkey of the folder entry in the HKEY_CLASSES_ROOT. [HKEY_CLASSES_ROOT\Folder\shell\NewMenuOption] @="Wipe it ..." [HKEY_CLASSES_ROOT\Folder\shell\NewMenuOption\command] @="D:\\FileWiper\\bin\\Debug\\FileWiper.exe \"%1\"" If a launch the program from a shell with an filename/folder as an argument it does it's job. But if the program is launched via the option in the Explorer menu and the selected targer is a folder (with a simple file it works), then the deleting fails with the exception " ... file being used by another process". It seems that the program keeps an open handle on the directory. The delete operation is made via Directory.Delete() ( tried also working with DirectoryInfo ...same result). Any one has any idea how can I get past this ? ------------------------------------------------------------------ LATER EDIT : I managed to track the problem after all. Simple stuff really, but forgot about it. Windows set the current directory for the program was set to be the target directory, so a simple change of the current directory was enough to get the program going. -- modified at 4:04 Friday 9th March, 2007

I have a problem deleting a directory, when that directory is already open by another application (like WExplorer, or TCommander). I get the well known exception ".. the process cannot access the file because is used by another application". How can I get around this ? (TCommander as far as I've seen can delete a dir, even if the dir is open by explorer, so something can be done...). Thanks in advance to all that may give me some info on this problem.

How can I add an option to the r-click menu from Windows Explorer ? Can someone help me with some info or a source-code ?

I want to make a secure erase file tool using c#. I know that there are some rules to be followed when making such a tool(overwriting the file many times,renaming, truncating and than deleting), but i didn't manage to find a document or some site where all this is explained (all i found so far are tons of programs that offer me secure delete solutions, and some well written but old linux document on this matter ... from 96 till now thing have changed a bit ...). Can any of you offer me some recent documentation, or pointers on this ? Thanks.

So I found out how to set a proxy for Internet Explorer. It's documented here http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wininet/wininet/setting\_and\_retrieving\_internet\_options.asp My problem is the following . Using the above mechanism allows me to set the proxy for all the protocols. I want to set ( programaticaly )different proxy values for different protocols( ex. one value for http, https and another for sock ). How can i make this?

As short as i can explain... I have a RichTextBox that i want to use for syntax highlighting. For coloring i use: richControl.Select(...); richControl.SelectionColor= ...; and it works . The text is highlighted using a list of keywords. Lets say that I have te following line in my textbox: I like icecream In this line "like" is a keyword and its color is red(for explanation sake) and all the other words are black. THE PROBLEM is that if I move the caret just after the word "like" and I start typing, the new inputed characters will also be red,and i wanted them to be black. How can i escape this problem?

How can i change programaticaly the position of the caret in a RichTextBoxControl ?

put two pointers in the child dialog class, that will poin to xParent, yParent (lets say pXParent,pYParent).. Before calling the child dialog initialize them with the address of the xParent, yParent something like childDlg.pXParent = &xParent; childDlg.pYParent = &yParent; childDlg.DoModal(); In childDlg class in the onSet(or whatever name you have for the pushing of the Set button) out something like this *pXParent = xChild; *pYParent = yChild; .... now the xParent,yParent will have the values of xChild, yChild
