    • Larry Roof's "Visual Basic Windows CE Programming" by Wrox Press, although written for the first version of VBCE, is still a great resource. Additionally, I believe that Larry Roof and Scott Lewis will be teaming up for some technical content as outlined on VBCE.COM.

  2. Q: What other products do I need in order to use VBCE 6.0? A: In order to use VBCE 6.0, you'll need the following:

    • Microsoft Windows 95 or later or Windows NT 4.0 with Service Pack 3 or later.
    • Microsoft Visual Basic 6.0 Professional or Enterprise Edition.

    Note that Windows NT or Windows 2000 is required for emulation.

  3. Q: Does VBCE provide database programmability? A: VBCE is able to provide database programmability via the ActiveX Data Objects control for the Microsoft Windows CE operating system (ADOCE), which provides a subset of ADO for Windows CE. The setup program for ADOCE is included on the VBCE 6.0 CD in the ADOCE directory.

    Here are some important notes regarding the two current versions of ADOCE:

    • ADOCE 2.0 only works on an H/PC 2.0 device that runs Windows CE 2.0.
    • ADOCE 2.0 does not support automatic Database Table Synchronization between the database tables on the desktop and the device.
    • ADOCE 2.1 only works on H/PC Pro 3.0 devices (running Windows CE 2.11), Palm-size PC 1.2 devices (running Windows CE 2.11 and with the Palm-size PC 1.2 SDK installed), and the H/PC devices with ROM upgrades (that is, running Windows CE 2.11).
    • ADOCE 2.1 supports automatic Database Table Synchronization.

  5. Q: Does ADOCE work in the emulation environment? ADOCE does work in the emulation environment. You'll need to ensure that you install the emulation components as a part of the ADOCE SDK installation from the VBCE 6.0 CD-ROM. You'll also need to ensure that you have copied your database tables to the emulation environment by using the EmpFile utility. For an illustration of how to do this, please see the EmulDB sample that ships with the ADOCE SDK. This sample is located, by default, in the following location: 
       C:\Program Files\Microsoft Visual Studio\Common\ADOCE\Samples\VB
    For additional information about the EmpFile utility, click the article number below to view the article in the Microsoft Knowledge Base:

  6. Q: Can I develop VBCE applications for Palm-size PCs? A: Palm-size PCs can be targeted with VBCE 6.0. The target Palm-size PCs must be running at least the Windows CE operating system version 2.11. Please note that the implementation of the Windows CE operating system on the Palm-size PC devices running the Windows CE operating system version 2.0 does not include sufficient COM support for VBCE applications.

    In order to target Palm-size PCs, the associated Windows CE Palm-size PC Platform SDK is required:

    For additional information about the Palm-size PC's support for VBCE applications, click the article number below to view the article in the Microsoft Knowledge Base:

    191478 INFO: Palm-size PC Does Not Support VBCE Applications

  7. Q: For which Windows CE platforms can I develop VBCE applications? A: VBCE 6.0 can currently target the following Windows CE platforms using the Platform SDKs provided by Microsoft:

    • Handheld PC version 2.0 (H/PC)
    • Handheld PC version 3.0 (H/PC Pro)
    • Palm-size PC version 1.2 (PsPC)
    For additional information, please see the following Microsoft Web site:

    Hardware Devices, Software Development Kits (SDKs)

    Also, please note that VBCE 5.0 applications can only be created for H/PC devices.

  8. Q: Are ActiveX controls supported in VBCE? Where can I get them? A: Yes. ActiveX is supported in Windows CE and you can use ActiveX controls in your VBCE applications. Currently, however, you cannot develop ActiveX controls using VBCE. Instead, you must use the Windows CE Toolkit for Visual C++ (VCCE) for ActiveX control development.

    Additionally, there are a growing number of third-party companies that are either developing or looking into developing ActiveX controls for use in VBCE. See one of Microsoft's Windows CE Web sites for the most current information:

  9. Q: Are the same Visual Basic controls supported in VBCE? A: Most Visual Basic intrinsic controls (such as CheckBoxes, TextBoxes, CommandButtons) are supported in VBCE. There are some differences in control appearance and behavior corresponding to differences in the Windows CE user interface model, however, and there are also differences in the Visual Basic built-in functions corresponding to differences in operating system features. For the most part, you will find that creating VBCE applications is very similar to creating Visual Basic applications on Windows 95, Windows 98, or Windows NT.

  10. Q: Can I use Windows 95, Windows 98, or Windows Me to develop VBCE applications? Yes. The Windows CE Toolkit for Visual Basic 6.0 can be installed on Windows 95, Windows 98, or Windows Me to develop Windows CE applications. The emulation environment, however, is available only under Windows NT or Windows 2000. Additionally, it is important to note that Windows CE Toolkit for Visual Basic 5.0 cannot be installed on a Windows 95, Windows 98, or Windows Me machine.

  11. Q: Can existing Visual Basic applications be ported to VBCE? A: You cannot directly port an existing Visual Basic application into VBCE due to some limitations and unsupported features in VBCE. The amount of work required to "port" an existing Visual Basic desktop application to VBCE will depend on many factors, including the complexity of the application and whether it uses features not supported in VBCE. It may be significantly easier to create a VBCE application from scratch than to port an existing Visual Basic application.

  12. Q: How do I debug VBCE applications? A: There are two methods of debugging available for VBCE users. The first is to use the emulation environment to debug your application right on your Windows NT development workstation. The second is to use the remote debugging tools provided with the Toolkit. These tools let you execute your VBCE application remotely on your Windows CE device, while at the same time monitoring and controlling its execution from your Windows NT or Windows 2000 development workstation.

  13. Q: How do I distribute my VBCE application? A: Distribution of VBCE applications can be accomplished using the Application Install Wizard supplied with VBCE.

  14. Q: Can I access Pocket Outlook contacts, tasks, and so forth from VBCE? A: Using the new Pocket Outlook Object Model (POOM) you can now read, create, and modify items used by the Pocket Outlook's Calendar, Tasks, and Contacts, as well as accessing and creating cities used by the World Clock.

    In order to access Pocket Outlook objects, the Pocket Outlook Object Model (POOM) SDK is required:

  15. Q: Can I call APIs in VBCE applications? A: The current version of VBCE allows you to call many Windows CE API functions directly. You can use the existing Visual Basic API Text Viewer to view the API information from the winceapi.txt file. In certain circumstances, because VBCE does not support structure data type, you may still need to use the Windows CE Toolkit for Visual C++ (VCCE) to create an ActiveX control to wrap the appropriate API calls and then host the control in VBCE.

    Please note that API calls could not be made from VBCE 5.0 applications.

  16. Q: Do I need a Windows CE device to run VBCE? A: You do not need a device to begin developing VBCE applications. You can create and debug Windows CE-based applications from your desktop. Built-in emulation technology provides the look and function of a device, right on your PC.

    It should be noted that in order to install ADOCE, Windows CE Services is required. Windows CE Services only ships with the devices. So although ADOCE will work in the emulation environment, currently it cannot be installed without the presence of Windows CE Services.

  17. I'm confused. Which devices and platforms will VBCE 6.0 and ADOCE run on? A: The following table lists what is supported and what is not:

    Handheld PC 2.0Handheld PC with ROM UpgradeHandheld PC Professional Edition 3.0Palm-size PC 1.2Palm-size PC 1.0
