I want to use the Close button as it shown in WPF windows application into my application.
Is it possible to get the design/image from the existing resources? Anyone points to me to get Pressed, Normal and Hover icons for close?. I could not get them all in one place to match each other..
I have attached close button image here..
That part of the window, termed the chrome, is not rendered by the WPF framework. You can create a chromeless window and render you own chrome. There are quite a few articles / blogposts that describe this. For example:

If you just want the images, try a screen capture tool.

Is it possible to take a screenshot of a partially hidden window without brining it to front? I know this is possible because the Screen Capture API already does this.
https://developer.mozilla.org/en-US/docs/Web/API/Screen_Capture_API/Using_Screen_Capture
The picture shows the popup when you initiate a capture process. You can see the same popup on Discord or Slack whenever you would like to share your screen. In the popup, you can see the list of the windows that I have open. Some of the windows are partially or completely hidden. However the popup shows the entire contents of them, which is surprising to me. The popup does not show minimized windows, which is fine. This works cross-platform.
I would like to know how the Screen Capture API does this as I have never succeeded in doing so. I personally tried with Win32 + GDI32 APIs but I was unable to take the screenshot of a hidden window. I would prefer a cross-platform solution but for now I am only targeting Windows 10+.
Thank you in advance.

#NothingIsImpossible
I am working on a wpf project and want to open browser (IE,Chrome,Firefox,Microsoft edge) on button click. After the browser opens I need to detect it's settings button on right corner and display an arrow image or a tooltip pointing to it.
I know how to open the browser using process.start but how to detect the settings area?
Get the browser's handle (HWND) after you open it (as shown in this answer), and read this answer on how to draw the arrow.
What you're trying to do is not easy, and has many points of possible failure, so I would avoid it, if some alternative was present.
I need to write a text recognition (from image) application. The main idea is that while my application is running, I may have the need to transform some text of an image into manageble text. So, in this case with the mouse I need to draw a square around the area that i need to capture and the software must convert the content of the extracted picture into text.
I solved the problem of image recognition. I also find a very easy way to capture from screen.
What I need to do now is be able to select with the mouse the interesting area that is over an other running opplication (for example over a webpage or over an image opened in Paint). That must be like the screencapture on windows7, you create a selection of the screen and this is saved like a picture.
By looking around, I didn't find anything and I don't knwo where to start.
Many thanks
You can achieve that using either a 'tricky' easy way or a real but difficult approach.
The tricky way
Screen Recorder applications usually use this approach:
Whenever user wants to select an area, you display a full screen border less Window with 0% opacity, then user attempts to select the screen area, and he is actually selecting your Window area, so you can receive mouse events and display/draw a rectangular shape to show the selection area to the user.
In this approach, the program needs to know when to display the Window and when to hide it. This can be done by for example defining Hotkeys for capturing:
Program registers a hot key using RegisterHotKey to Windows.
User presses and holds that hot key
Program displays the tricky Window
User selects the interested area, program receives that area using mouse events of the tricky Window
User released the hot key and program hides the Tricky window.
The real way
Using this way, you need to set a message hook in order to receive mouse and keyboard events while user is interacting with desktop not your program. This is not an easy to accomplish approach and I recommend you the first one.
I am trying to develop an windows application like Google chrome Browser in WPF
using C#.I am facing problem in making my own Custom Window and Placing Tabs at the Place of the Title Position of that window.
Please suggest me how to go for it, is there any tool for this ?
Guide me please..........
Updated:
Hi Friends Thanks for your active responses and I also followed the links you gave and the way you told, but still I have doubts in developing the application please give me some more ideas where I can develop this application by using Google Chrome like controls. I want to give my application Google Chrome like look and feel.....
Google Chrome essentially custom-draws the non-client area of its window to remove things that it considers superfluous like the title bar. That's how it gets the tabs to replace the title bar of the window, just like how Microsoft Office places its "pearl" and quick access toolbar in the title area of document windows.
To do something similar in WPF, you may find this article useful: Link
Remember that any time you re-implement the standard windows chrome, you're going to have to handle a bunch of stuff that Windows normally makes transparent to you, like resizing, minimizing, maximizing, moving, and closing a window.
It is worth considering that both Google Chrome and Microsoft Office applications (among others) behave differently depending on whether Aero Glass and the Desktop Window Manager (DWM) are present/enabled. You're going to have to make sure that your application degrades gracefully when these things are missing. I would advise being sure that you can really make a convincing case for the necessity and benefit to the users before you invest all the time and energy it takes to do things like this in your application.
I just finished a Google Chrome-like Tab Control for WPF. You can find the project at https://github.com/realistschuckle/wpfchrometabs and blog posts describing it at
Google Chrome-Like WPF Tab Control
ChromeTabControl and Visual Children in WPF
WPF Chrome Tabs Functioning
Hope that helps!
It appears that Chrome draws its tabs within a limited region of the title bar area. When enough tabs are open, the width of existing tab controls is reduced to make room for a new tab.
I would suggest that you adopt a similar strategy by drawing your tabs in a suitably sized Rectangle which does not intersect with the caption buttons (Minimize, Maximize Close) and reducing the width of existing tab headers when the region becomes full
[Update 1]
While I haven't seen your code, I would suggest this happens because the tab header (the part displayed in the title bar area) and the tab page (the part covering most of the screen) are a part of the same control and are drawn as a unit, so when you try and draw the header in the region the tab content is redrawn too.
If this is the case, then you need to draw the tab header and the content page as separate controls and maintain some state in the tab that indicates which tab page should become visible when the tab is selected.
I'd like to create a popup dialog box in silverlight in which i can manipulate controls, enter data, and return a value. I want it to be modal, so that when it is open, the page "Below" is inaccessible. I havent found an easy way to do this yet. Any suggestions?
I know the question asked for a Silverlight 2 solution but in Silverlight 3 (Beta now, RTW in July 2009) there is a built-in ChildWindow that can do everything you're looking for.
I haven't found a perfect solution either. The closest I have seen is this:
Using Popup to create a Dialog class
If it is ok to be non-modal, you can try this tip using HtmlPage.PopupWindow().
How to Popup a Browser Window
I'm new to the Sliverlight framework and am just starting to figure it out, but I have a similar need for a popup modal dialog box. I just tried an idea that looks promising:
I created a Rectangle (named "Shield") that covers my entire application area. It exists on top of everything in the main app. I set the fill-brush to White, and the opacity-brush to 81% so that the main app contents show through, but lightly (as in disabled). Then make sure the "Shield" is hit-testable. Now, when the "Shield" is visible, it will also, in effect, block all input to the controls below (at least from the mouse, haven't tried keyboard yet). When the app initializes, set the "Shield" visibility to Collapsed. In that state it won't block input to the main app.
The dialog box is then constructed on another canvas element that exists in the z-order on top of the shield. Normally the dialog box will be invisible, but when I need it, I just set the "Shield" to visible, and the dialog to visible. Since the dialog is on top of the "Shield" I get a very modal-like behavior. When the dialog box is closed, make both the dialog canvas and "Shield" canvas invisible again and the main app is again active.
I'm sure this the most brute-force way of doing it and that I will eventually zero in on a more elegant construct, but it works for now.
A more elegant solution is here:

I had the same requirement and ScottGu's Building a Basic Modal Dialog Using a User Control was the best solution that fit my requirement.
Here's a free library that provides one: http://www.vectorlight.net/demos/popup_dialogs.aspx
