I'm trying to create a windows form app that will be able to handle icons from desktop, like keeping them and changing their properties etc...Can you please give me some advice how to create this pseudo-desktop? I haven't found anything that allows me to place .lnk shortcuts on Form.
Thanks
For that, you do not need real LNK files (For creating them you need to use p/invoke).
Just make a ListView with Icon-View. If the User doubleclicke on a item you can handle the click and launch whatever you want to associate with this action.

I want to build a software.
This software will just get the path of currently selected file.
Suppose I click a file on my desktop.
Now I want to get the path of this file.
So whenever a new selection is made just get the path of newly selected file.
Any ideas?
The windows Desktop window is a ListView Control like in the end (at least it was in Windows XP...) so if you need to know selected item of a ListView you basically need to get the handle of the desktop and check what has been selected.
Not sure about windows Vista and 7 bit I guess it's not too different, as David has commented, if you want this for every single explorer window could be more difficult but should still be possible, have a look here for a start:
How do I get the window handle of the desktop?
Maybe you should look at the OpenFileDialog class
I think you can use what Shaun had said about looking at OpenFileDialog.
You can also refer to this link below:
How to use OpenFileDialog
That link also teaches you how to change the title, filtering files of type and 1 or 2 others regarding OpenFileDialog.
Hope this helps.
I've been searching for days about this, but haven't found anything.
I am trying to find out how I can add a context menu item to the windows explorer. I do not want it for specific filetypes, BUT I want it to appear on everything inside a specific path.
For example, I want right-click menus of anything inside "C:\folder" to contain this item, but it shouldn't appear outside this folder...
Is that possible?
Any help will be really appreciated!
Thanks in advance,
John.
The normal way this is achieved is to add it to the Registry under:
HKEY_LOCAL_MACHINE/Software/Classes/Folder/Shell
However in your specific case you want to do some preprocessing before it is displayed (eg is it in the specified directory) which wouldn't work with a simple registry alteration.
I think there is a way to force you way into any operation and add a hook to it. I'm talking about old school knowledge now though and I cannot think what the technology would be called. I think its how you would have, for example, forced your way into the rendering engine to put custom skins on normal explorer windows or inject an extra button into the title bar of apps like you used to see back in the day.
It just occurred to me that adding a button to the windows title bar might have given a search starting point, I found this article which refers to subclassing windows components and injecting your own behaviour. I think that is what I'm talking about above:

Hope this gives you a new direction to search in.
I need to create a dialog that allows user to choose between several rather complex actions. I really like the usability of the windows 7 file replace dialog and I think it would suit my needs very well. Here's a screenshot for reference:
Is it possible to use the controls that were used for windows dialog? If not, how would you recommend creating UI similar to this dialog?
Seems like this could easily be done with a window containing a few labels for the text and three custom controls - with some images for the arrows and file icons - each of which changes their background image when the user mouses over them - and fires an event the window picks up on when they are clicked. Fairly standard WinForms stuff.
Is there a particular part of the process you need some extra help with? Like, for example, the mouse over?
I would like to add a control to my app where the user can browse his local file system and select a directory. I would prefer to host this control on my main app window, and not do this via a pop-up dialog.
There isn't one built in.
You can either use the WinForms file/folder browser, search Code Project or similar site for someone else's implementation or write your own.
I've found one on Ookii Dialogs that includes some other standard dialogs.
If you want to host the controls on your own form, use controls from Shell MegaPack.WPF
How to put a C# programm (ex WPF or WF) under desctop Icons (like a wallpaper)?
I want my Old Good XP Active Desktop made by a some open source C# programm on my Win 7!)
Something like this - Fences .
They have there "windows" appearing underneath icons. I do not want to manage Icons - just put my window under them... BTW any one knows about such operations in other OS’s (Mac etc)?
And I DO NOT WANT TO MANAGE ALL THE ICONS ON MY OWN LIKE bumptop
I think it is quite possible, try this:
Find handle to window with the class "Progman".
Create some window in your application (or, perhaps, in some separate application, you will see the purpose later) and turn off its borders.
Set the parent of the newly created window to desktop handle.
Set the parent of "Progman" window you have found previousely to the window you created.
Desktop will be put on a window owned by your application and it will be possible to manipulate it in the way you want (namely, put something under it).
Also, do not forget to restore desktop's parent when application owning it is closed.
Look for FindWindow, GetClassName and SetParent at http://www.pinvoke.net/
Short answer is you can't really do it (in managed C# anyway). If it's possible, you would need to use Interop, and you'd likely be calling something that Windows doesn't offer as an API.
... although... as Ole Jak mentioned, Stardock looks to be doing it somehow...
The desktop is its own contained item. The same process handles the icons and the wallpaper "behind" those icons.
You are allowed to change the wallpaper to a different image, and you used to be able to create an Active Desktop where HTML content would be displayed, but this was discontinued in Vista.
What are you actually trying to do? Maybe there's another way to achieve a similar result?
There was DreamScene for vista. You could put a video as explorer background. I dont know if you could run a C# program to output the background video.
