After the Build succeeds (you should see a build succeeded message at the bottom of the screen) click on Start Debugging (green arrow) by the side of the Debug menu item. This displays the Deploy Pocket2 window as shown. There are a number of Pocket PC devices shown with the highlighted as the default.
"For years, stock car racing was pretty well closed to cigarette manufacturers, but we jumped when we saw this opportunity," Victory Brand CEO Steve Swick admitted, "The sport fits our demographic, with the huge numbers of adults who follow it, and with the large numbers of highly brand loyal smokers who are fans. We believe they will see our support for NASCAR racing and will try the VB brand.
Objects are listed in the order that the screen reader will read them in. The number next to each object indicates the position in the sequence. Objects without a number will be skipped because they are marked decorative.

The GetDeviceUniqueID() function returns a "hash" of the manufacturer assigned serial number and other information to give each device a unique number. It is unique to each device, but it is not the serial number assigned to each device by Juniper Systems.
If you are writing software specific to our Windows Mobile Field PCs, or have pre-existing software which already uses the multiple, varied methods for retrieving the individual serial number from different hardware device manufacturers, you can programmatically identify the Juniper Systems assigned hardware serial number using the JSAPI GetSerialNumber function as explained at our Custom APIs (Application Programming Interfaces) developer links.
To get the serial number, the Allegro contains a unique DLL called "AllegroAPI" that provides functions such as one to return the serial number. The "GetAllegroSerialNumber" function in the AllegroAPI.dll is as follows:
The AllegroGetSerialNumber function returns the unique serial number of the device in a zero-terminated, fixed length (leading zeros) character string. If you only want to know the length of the serial number (to allocate space, for example) pass NULL for szSerialString.
The point of licensing isn't to stop crackers from cracking your software. The point of licensing is to increase your revenue by preventing casual piracy (using serials over and over again). There is real money to be made by stopping casual piracy.
There are some variations of serial-only licensing. One such variation is asymmetrically encrypting a large block of data and including this encrypted data in a license file for the user. But the principle behind all of these variations remains the same: the license (whether it's a product key or a file) can be shared over-and-over again.
False positives. A false positive in online activation is when the licensing (rather, your program using the licensing) sees 2 completely different computers as the same. That is, with a false positive match a user can use the same serial over and over again on multiple computers.
The Philips Data Export protocol that conveys this data is complex, not well documented, and is not supported to any great extent by Philips. The Data Export Protocol is described in a 300+ page document that is convoluted, misleading, and incomplete. I spent about 600 hours working out the details required to implement this protocol in a Visual Studio .NET control. My original time estimate for this project was 40-80 hours. You might imagine how frustrating this project became over time! Regardless, I completed it, though far behind schedule.

Back to top Publications Visual Basic Programmer's Guide to Serial Communications A Tutorial: Porting VB6/MSComm32 applications to Visual Basic .NET ASIN: B009AE7NZW Published September 2012 by Grier, R.Visual Studio .NET and its supported languages, such as VB and C# provide a modern and well supported application development environment. There are a wealth of legacy VB6 programs that can benefit from moving to VB .NET.This tutorial is devoted to those VB6 applications that rely on serial communication to exchange data with other computers or devices. Porting VB6 based serial communication programs to VB .NET can be tricky. The tutorial guides the porting process and provides critical information and working example code to illustrate the process.The tutorial also provides help for maintaining legacy VB6 applications by employing COM Interop controls and forms developed using VB .NET to add important capability that is best done using .NET tools.
One of the major benefits of using Visual Basic is that the language has been stable for a very long time. The significant number of programmers using Visual Basic demonstrates that its stability and descriptive style is valued. Going forward, we do not plan to evolve Visual Basic as a language. This supports language stability and maintains compatibility between the .NET Core and .NET Framework versions of Visual Basic. Future features of .NET Core that require language changes may not be supported in Visual Basic. Due to differences in the platform, there will be some differences between Visual Basic on .NET Framework and .NET Core.
The 1-Wire bus is a simple signaling scheme that performs two-way communications between a single master and peripheral devices over a single connection. A powerful feature that all 1-Wire bus devices share is that each and every device, in a chip or an iButton, has a factory-programmed registration number that will never be repeated in any other device. In effect, every device is unique. This allows any single device to be individually selected from among the many that can be connected to the same bus wire. Because one, two, or even dozens of 1-Wire devices can share a single wire for communications, a binary searching algorithm is used to find each device in turn. Once each device registration number is known, any device can be uniquely selected for communication using that registration number to address it.
The first part of any communication involves the bus master issuing a reset, which synchronizes the entire bus. A slave device is then selected for subsequent communications. This can be done by selecting all slaves, selecting a specific slave (using the registration number of the device), or by discovering the next slave on the bus using a binary search algorithm. These commands are referred to collectively as network function or read-only-memory (ROM) commands. Once a specific device has been selected, all other devices drop out and ignore subsequent communications until the next reset is issued.
An integral part of the unique registration number in each slave is an 8-bit family code. This code is specific to the device model. Because each device model performs different functions, this code is used to select the protocol that will be used to control or interrogate it. See Table 1 for a mapping of family codes for Maxim 1-Wire parts.
There are three sets of portable source files defined as 'general,' 'userial,' and 'other.' The first set is general purpose and is intended for platforms that already have the primitive link 1-Wire communication functions (general). This is the lowest level that is hardware dependent. The second set of portable source files assumes that the user has a serial port (RS-232) and wishes to utilize the 'Universal Serial 1-Wire Line Driver Master: DS2480B' (userial). This chip receives commands over the serial port, performs 1-Wire operations, and then sends the results back to the serial port. The source code converts the intended 1-Wire operations into serial communications packets to the DS2480B. The only module that need be provided for a platform are the serial port read/write primitives. The DS2480B is the interface chip used in all of the DS9097U series serial adapters. Finally, the third set of portable source files deal with specific 1-Wire adapter functionality and/or does not quite fall into the previous categories (other). An example of this deals with the USB port, specifically utilizing the DS2490 USB to 1-Wire bridge chip. In many ways, this is similar to the general build, but has been modified for DS2490 specificity. No matter which file set is used (general, userial, or other), in the end, the same API is actually published to the software developer.
These sets of portable source code files implement the same 1-Wire API functions and are interchangeable. Figure 4 shows the available API for version 3.xx of the 1-Wire PD code base. Note that the nonmemory-device-specific functions are not listed in detail due to their large number. Figure 4 maps the source files that provide the functions and the required modules for new platforms.
Keep in mind that some builds require native 1-Wire adapter drivers or equivalent. As most OS platforms have built-in serial port drivers, the userial builds of the 1-Wire PD API do not need any other driver. However, for USB and parallel port 1-Wire adapter support, native or cross-platform drivers will need to be installed. References to the appropriate driver downloads are available in the documentation of the actual 1-Wire PD Kit builds available online.
