I am creating an Add-in (using C#) for Microsoft Word and want to trigger some functionality when some text/image etc. is dragged from any source and dropped into Word. So basically I want to trap the Drop event in Word. However I am not able to find any Word API which helps in this. Can you please help in this?
No such beast exists.
The best (easy-ish) approach you can hope for is to watch the DocumentChange event, and try to monitor what changed (it'll be located at the current location of the "Selection").
A much hardy way would be to subclass the main Word Window and watch for whatever Drag/drop messages are being exchanged, and intercept them as appropriate.
The SelectionChange event can sometimes be used for this. Sometimes, because the selection will not always contain the dropped content. E.g. if you drop an image into a document, the image will not be selected.
A better alternate is to use a transparent window that you overlay on top of the Word window. This window is initiated when the drag process starts and placed on top of the document window. The drop operation is then received by this window instead of Word, so you know exactly what came in and at which location it was dropped. You can then translate these location coordinates into corresponding document location (using RangeFromPoint() method of Window class) and do whatever you need to do with the dropped data. After this you simply hide your transparent window and everything goes back to normal.
A complete implementation of this approach along with source code is available in this excellent MSDN article.

So I'm sure there's an easy way to do this but I don't know the exact terminology for what I'm wanting.
Essentially in my C# xaml uwp app I have a couple objects that need to have details added to them, kind of like file properties. I have a button that I would like to open up another window (still part of the app), just to enter in the properties. I just don't know the terminology to look up what this window would be called or find documentation for it. So the exact same as when you're in a file browser and you open the properties of a file; it opens in a little extra window that you can drag around.
I don't want to be able to use the main window while the properties window is open, and of course they need to be able to transfer data between one another.
In my previous apps I've simply made a grid that appears over everything else in the middle of the app and shaded the outer area. A workaround as I didn't know how to do this.
Can anyone help me out?
Maybe you can use Dialog refer to https://learn.microsoft.com/en-us/windows/uwp/design/controls-and-patterns/dialogs-and-flyouts/dialogs.
Dialog controls are modal UI overlays that provide contextual app information. They block interactions with the app window until being explicitly dismissed. They often request some kind of action from the user.
As a learning project in C# .net I am re-creating a Gnome 3 plugin for seeing who of the streamers you follow on Twitch is live. I have the settings form done, I am now working on the interface that is viewed from a click on the taskbar.
This is a rough image of what I want the interface to look like. When two or more streamers are live the interface would add another block and resize the form vertically similar to the menu for selecting a Wifi network in Windows.
What would be the best way for me to complete this?
My current thought is to maybe create a custom control and just place those inside a FlowLayoutPanel with some kind of code to change the vertical size of the form to match the added entries. Maybe this can be done without a custom control and be done with code inside a FlowLayoutPanel? I'm not too sure.
Ideally I would also have a click event in the panel for each streamer so I could then open a browser to their channel. A slight highlight would also be a plus (maybe change the background colour based on mouse hover).
Thanks in advance for any suggestions!
I have a c# application that runs in the bottom right corner of the page, i was wondering how i could go about making my application appear when the user selects some text anywhere (say a pdf, browser etc) and then right clicks, goes to my custome selection bit say and it pastes that text in to my running application.
If anyone made any sense of that could you advise me in to what i need to be researching to get it done.
Thanks
I've got this dictionary which does something similar.
Here's its mode of operation (or at least what I think it does)
When there is a double click, it sends a key command (probably Ctrl+C) to copy the selected text. It then reads the text from the clipboard.
For your purpose, you could implement the mouse listening and sending keystrokes with this article I found on CodeProject: InputManager library.
You then retrieve the copied text from the clipboard and do whatever you want with it.
Have a look at a Clipboard monitor
You can hook into the windows messaging api, probably there is a Text-selected event.
I've a winforms app that "docks" to the taskbar
I'd like to autohide the form and make it appear only when the mouse goes near/over the form
any suggestions ?
Install a global hook onto the mouse-move event and check to see if it is within the form boundaries. Should work even with the form hidden. If not just store the location as a rectangle and check against that.
Code for a simple and handy global hook implementation can be found at:
http://www.codeproject.com/KB/cs/globalhook.aspx
I've used this method to create "hotspot" functionality to a user desktop.
I'm not sure it is exactly answering your question, but there is a sample of this on Codeplex...
http://remoteaccessmonitor.codeplex.com/
Browse the source code and check out the MinimizeToTray.cs file - it has examples of pop up messages when hiding and I think its default behaviour is to re-appear on click (although I imagine this could be changed).
You could.
Poll mouse coords until it's within a certain radius of your app.
Position an invisible, always-on-top form above the docked app and have it fire a MouseEnter event.
That's all I can think of really. Either.
I'm searching a C# component or code snipped that does something like that:
I want to inform new users about the most important program functions if he opens a new window for example.
It should be a box showing text (formated if possible) that is of course not modal and has some mechanism to 'go out of the way' if the user enters the textbox area. So that he can access what's underneath it. Alternativly the window could also stick to the border of the window, but there needs to be a way that this also works if the window is maximized.
So I want to present him with a short introduction of what he can do in every corner of my app most painlessly.
Thank you!
I use a "bar" at the top of every window to display some information about the current window/dialog.
Use tooltips. They can be programmatically controlled, and you can have them appear at will. You'll need to add the functionality to your app to keep track of what tooltips have been shown to the user already.
You can add a "balloon" style by setting the IsBalloon property to true.
You can also replace them with smaller descriptions for when the user wants to hover over the control and have them displayed again.
I'm already using tooltips heavily. However, they aren't very practical when displaying bigger amounts of data and they are bound to specific user actions.
Have you considered having a contextual menu for each form / page which contains links to Adobe Captivate style presentations for each available task? That way the user can investigate an example of how to achieve a task relating to what they are trying to achieve from within the application / site.
This approach would require a good deal of maintenance and management if your code changes regularly but coordinating it with a training department can provide rich help features in your application.
