If your admin account is different to your user account, you must add the user to the docker-users group. Right-click to add the user to the group. Log out and log back in for the changes to take effect. It includes a change to the terms of use for Docker Desktop. Click the checkbox to indicate that you accept the updated terms and then click Accept to continue. Docker Desktop starts after you accept the terms. If you do not agree to the updated terms, the Docker Desktop application will close and you can no longer run Docker Desktop on your machine.

You can choose to accept the terms at a later date by opening Docker Desktop. For more information, see Docker Desktop License Agreement. This tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub. When an update is available, Docker Desktop displays an icon on the Docker menu to indicate the availability of a newer version.

Additionally, the Software Updates section in Preferences Settings on Windows also notifies you of any updates available to Docker Desktop. Starting with Docker Desktop 4. For more information, see Software Updates. Click Download update When you are ready to download the update. This downloads the update in the background. After downloading the update, click Update and restart from the Docker menu.

This installs the latest update and restarts Docker Desktop for the changes to take effect. Read the information presented on the screen to understand how the changes impact you. Yes, arrays are supported in the Visual Basic runtime.

However, I don't see this as a huge problem. In general, I believe that developers of large applications will hide most complexity inside a DLL or in an ActiveX control. Most of the variables that you'll need will be used to manage both the user interface and the interactions between components.

Developers who have used the Api Text Viewer tool from the desktop will be happy to know that it can also be used with eMbedded Visual Basic. As mentioned earlier, it gets placed within the Start menu next to the other eMbedded Visual Tools. It provides function declarations, constants, and structure type information for calling Win32 functions from Visual Basic.

Since eMbedded Visual Basic doesn't support user-defined types, only the function declarations and constants are useful. A quick perusal of the definitions file showed that not all Win32 functions supported in Windows CE are present CreateWindow, for example, is missing.

Assuming that you are familiar with Visual Basic, the first application you write for Windows CE will probably take a bit more effort than would be required on the desktop. That was certainly the case for me when I wrote VBEdit. Part of the extra work was due to the fact that fewer features are present in eMbedded Visual Basic than I had anticipated.

Another commonly overlooked fact is that it simply takes longer to build on one computer and then run on another. The downloading of the application takes time, as does the downloading of all the sundry support files like the Visual Basic runtime and the supporting ActiveX controls.

Even if things have been downloaded once, a check is done every time to make sure that things are as they need to be. VBEdit lets you create and edit Unicode text files. Most of the code in this program handles the various menu selections.

I incorporated three ActiveX controls that were part of the standard set that ships with a common dialog control, a file system control, and the Pocket PC menu control. When I was finished designing my program, I ran the Application Install Wizard, which packaged up everything that would be needed to ship my program.

Figure 7 lists and describes the files that were included. The code that I wrote had gotten parsed and tokenized, so that my original source code isn't available for you to read unless you want to go to the trouble of reverse-engineering this file. My program by itself was a mere 8KB. As written, my program required another KB of ActiveX controls. It is reasonable, I think, to regard this as overhead for my program, since these controls are not installed on a typical Pocket PC.

This KB image is listed here as part of the total cost to run my program, although you'll have to determine whether these are in ROM on the device you are targeting. If not, they'll need to be installed to the object store of the target device. Object store compression will ease this cost somewhat because of the 2x compression that you get for free. It provides the way to write the smallest and fastest applications.

Even if you don't write your entire application using Win32, you'll need to write some code using it in one form or another no matter which programming technology you adopt.

Win32 is important to Windows CE because it represents the only programming API supported natively by the operating system. This is the first time in many years that an operating system from Microsoft only supported one API.

But with Windows CE, there's just one: Win In particular, with a few mouse clicks you'll be able to create everyone's favorite first program: Hello World. Even if you're an old hand at programming in Win32, you'll probably want to review the code that the wizard creates.

The reason is that there are some device-specific function calls that are demonstrated very nicely. In particular, if you are getting started with the Pocket PC, you'll want to know how to tame the software input panel SIP. Figure 9 Software Input Panels. In some cases, your program will display the SIP automatically, which will certainly be the case when focus gets passed to an edit control. For all of these cases, you want to make sure you respond in an appropriate manner: a window might need to be resized, some scroll bars might have to be moved, or drawings might have to be scaled.

Unfortunately, there were a few changes made to the Pocket PC at the last minute, and some of these changes mean that you'll need to edit the Hello World program that the wizard creates. Figure 11 outlines two changes that you'll want to make to a Hello World application to bulletproof its SIP handling. While these changes are pretty simple, it took a bit of futzing around to figure out that they were needed. The first is that a data structure needs to be initialized.

The primary benefit of calling this function is that it resizes your program's main window to accommodate the SIP. This is especially important if your program tries to draw into its entire client area because the SIP will clip any such drawing if the window is not properly sized.

A window that's not sized properly also becomes obvious if you have a scroll bar, because the SIP will likely also clip a scroll bar that is attached to an improperly sized window. Here is the code to handle this:. One final change that I always like to make to the typical Hello World application is to add an OK button to the caption bar.

This makes it convenient to shut down an application that you are developing. Here is the code I like to use:. If you haven't used a Pocket PC before, you might wonder why an extra step is needed to shut down a program. Users don't shut down applications; they just run forever.

Programs don't ask users if they're sure; a program always assumes that a user is sure. If a user erases something, it is gone for good. In other words, you'll probably want to have an OK button on the caption bar of your programs while you are developing them. And OK buttons will appear in dialog boxes.

But, in general, your shipping Pocket PC-based applications won't have a Close menu, an OK menu, or any desktop trappings that allow them to close or require a user to think about closing an application.

Like VBEdit, my Winbased editor uses the built-in common dialog boxes to allow the user to select a file to open, and also to pick a name and a location for saving a file. On the subject of opening and closing files, it's worthwhile to point out how files are viewed on the Pocket PC, since it is different from the desktop.

There are two views that are interesting here: what really exists, and what the user sees. What really exists is a hierarchical file system that looks an awful lot like what you have on the desktop. There is a Windows subdirectory and a Program Files subdirectory, both of which contain the kind of things you find on their desktop counterpart.

Things look a bit different to a user. In particular, the common dialog boxes only let the user see into a directory named My Documents.

For programs that bother to show users the file system, what they can show the user is an area set aside to hold user files. This is a nice thing, since it prevents users from mucking about with OS or application files.

Of course, developer types always like to see what is really there. Fortunately, there is a File Explorer program, which is basically a Pocket PC version of the desktop file explorer. With this utility, you can look into any subdirectory, as well as onto a CF storage card you might have plugged into the CF card slot.

From a pure lines-of-code perspective, Visual Basic came out ahead as the smaller of the two. From the perspective of final executable images, though, the Winbased program was clearly the leader. Most drivers for built-in devices follow a layered architecture because Microsoft provides layered samples for them. Nonetheless, an OEM can re-implement those drivers to better fit its devices.

The only drawbacks are that the modified MDD might not be as portable as the original of course, this might not be an issue , and changes might be required in the PDD. Microsoft provides a driver development tool called Platform Builder. Actually, Platform Builder allows building, downloading, and debugging complete Windows CE images including device drivers for various processors. It integrates an editor, cross-compilers for all supported processors, a linker, an integrated debugger, an image loader, and a flock of additional tools.

New to Platform Builder v. It also includes the device driver test kit DDTK to test the native drivers extensively.

Real-time considerations. Windows CE v. Device drivers are not immune to those changes and can, in fact, diminish real-time performance if not properly implemented. As mentioned earlier, nested interrupts are supported based on their priorities. Note that some architectures do not support nesting interrupts on their priorities x86 is one , so this concept does not always apply.

If it does, ISRs must be written accordingly. For instance, critical sections might require turning off all interrupts. This is even more true if, for performance consideration, the interrupt is directly processed in the ISR instead of the IST. In such a case, turning off interrupts directly impacts the systems' interrupt latency, and may degrade the overall system performance if not carefully fine-tuned.

Interrupt service threads are subject to premption by the scheduler based on their priority, a situation that may not be acceptable in some cases.

Under 3. Real-time processing can be achieved by raising a given IST's priority, but again, the impact of doing so must be reviewed against the other ISTs in the system. It is a good practice to store a driver's priority in the registry where it can easily be modified, as opposed to hard-coding it in the driver.

This naturally requires the driver to load the priority value from the registry and adjusts the IST's priority accordingly once created. An IST can also set its quantum the time it executes before the scheduler kicks in to a value other than the default which is set in the OAL. In particular, an IST can set its quantum to 0, which means run to completion.

However, whatever the quantum value is, interrupts are still processed. Should a higher priority thread become ready to run as the result of processing an interrupt, this thread will preempt the current thread. Therefore, run-to-completion is useful if the driver doesn't want to be interrupted by another thread of the same priority in a multi-threaded driver for instance. Running to completion has little impact on the overall system performance, since higher-priority threads can still preempt as needed.

There is no doubt that developing drivers for Windows CE 3. However, it is important to note that custom driver development requires substantial work, ranging from a few weeks to a few months.

Engineers new to CE typically require three to six months to go through the steep learning curve, although training class will probably reduce the period of time. No matter what approach you take, it is important to allocate ample resources and time for Windows CE device driver development. Since , he's been involved in the development of Windows CE devices, from platform adaptation to application development.
