what's the different between window and panel in Extjs ? is it fine if i use window to display and handle too much data from database ?
Window is a specialized panel intended for use as an application
window. Windows are floated, resizable, and draggable by default.
Windows can be maximized to fill the viewport, restored to their prior
size, and can be minimized.
So if you don't need any of the features the window has - use a panel.

WinForms .NET 6.03 (C#)
In a Form that has a traditional menu and toolbar docked across the top...
I have a split container (vertical splitter) in the left panel I have a toolbar docked to the top and a user control filling Panel1 below the panel's toolbar.
When I resize the panel, the toolbar disappears and the user control shifts up in the panel.
This was not a problem in .NET 4.6. I'm only seeing it now that I'm building in .NET 6.03
Is there a fix?
It turned out that this was a z-order problem. Somehow during execution, the toolstrip was losing it's topmost condition regarding docking.
I am docking another application's window inside of my WPF window using HwndHost. To do this, I have to set the WS_CHILD style attribute of the window I am docking and I lose the system menu of that window which is not acceptable. Using HwndHost there is no way around this since it will throw exceptions if that attribute is not set.
My question is;
Since my application doesn't use a system menu, is there any way to directly copy the system menu of the docked application to my app's window? The WinAPI menu functions I'm aware of would all require me to build up the menus from scratch and I don't know how I could hook those menu into the hosted application.
I'm not sure if it matters, but the two windows are within the same process. My application is a plugin of the application window I am docking.
Use GetSystemMenu to get an HMENU for the system menu for the given window. You should be able to cross-reference your own window's system menu with the docked application's system menu, copy across any that your own window doesn't have, and forward them on by handling and forwarding the relevant WM_SYSCOMMAND messages. Or maybe just copy the whole system menu and forward all of them on.
This will probably require a bit of trial and error to make it all work (especially if the docked application isn't expecting to be used this way...) but the above might help get things started.
I have a Winform application and I would set two different icons, one for the application shown in the taskbar and the left-upper corner of the window and a different one for the ALT+TAB switch.
The properties Icon of the Form sets only the small one but seems that it is used also for the ALT+TAB view.
In Visual Studio 2012 I've already tried to select a diffenrent icon under Project Properties > Application > Resources > Icon and Manifest.
Any help will be appreciated!
I got the solution which is quite simple. Basically I created a multi-size icon with the same image (64x64, 32x32...) and I changed the 16x16 size with another icon. In this way you can have different type of icon inside one.
I want to open some custom Menu when the user left-clicks on the titlebar and / or the small icon of my WPF Application. The Menu itself must not open within the titlebar or overlay the titlebar! It's only a nice-to-have feature, but not a must. It can open within the Application itself.
I know that this is "easily" possible with creating a custom window in WPF, but i don't want to do this to maintain all the default window behaviour for now and for future windows versions, as my application lifetime is assumed to be several years.
So my question is:
Can i register some Eventhandlers to the MainWindow's Titlebar without changing the default Window style, behaviour and appearance?
Is it possible to mark the captured Events as "used" or "handled"?
I would like to change the size of the window's icon in the xaml window.
I know that I can hide the window's title bar and create a custom title bar, but is there
any way to change the icon size alone ?
I was looking for many forums and couldnt find a proper solution.
How do I change WPF Menu's icon column size?
The above link explains for menu's icon size but I want for the window's icon
The standard window chrome is handled by the Windows.
I guess the reason for that is consistency across applications which is also the reason why I dislike the Office/Ribbon replacement of the standard chrome.
In Windows 8 Metro applications there will be no window chrome so all UI will be up to you.
In Windows 8 desktop applications (and Windows 7 applications) you will need to replace the entire chrome completely.
