This tutorial will show you how to input data into a text box and get a barcode image from it. You will also learn how to work with clipboard and checksum controls.
Controlling Program Flow Visual Basic / Getting Started
To control the VB program flow, we can use various conditional operators. Basically, they resemble mathematical operators. Conditional operators are very powerful tools, they let the VB program compare data values and then decide what action to take, whether to execute a program or terminate the program and etc.
Staying in Control War Against Bugs Visual Basic / Error Handling
Program bugs are highly ecological because program code is a renewable resource. If you fix a bug, another will grow in its place. And if you cut down that bug, yet another will emerge; only this one will be a mutation with long, poisonous tentacles and revenge in its heart, and it will sit there deep in your program, cackling and making elaborate plans for the most terrible time to strike.
Basic drawing program Visual Basic / Complete Projects
This tutorial doesn't just show you how to make a simple drawing program, it also teaches you things like error handling. Good for beginners who want some hands-on approach.
Distribution of Applications Visual Basic / Miscellaneous
There are programmers out there who program solely for themselves. They write code/applications and no one but them ever sees their applications. However, most of you are like me and we want to revel in the accolades that our friends and peers heap on us when we provide them with exactly the right program to meet a need that they have expressed!.
Introduction to Procedures Visual Basic / General Development
A procedure is a set-aside assignment the compiler must take care of to complement a program. A program developer writes the procedure and a user would only see the result. There are two categories of procedures you will use in your programs: those that have already been created thus made available to you, and those you will create yourself.In v basic, like most other languages, there are two types of procedures: functions and sub routines.
Macronimous- Developing Windows Smartphone Applications using .NET CE framework Visual Basic / VB.Net
A Pocket PC (PPC) is a handheld-sized computer that runs a specific version of the Windows CE operating system. It has many of the capabilities of modern desktop PCs. Some of these devices also include mobile phone features. Pocket PCs can also be used with many other add-ons like GPS receivers, barcode readers, RFID readers, and cameras. PPC are enhanced to Smart phones using Windows Mobile v5.0 operating systems.
API Visual Basic / General Development
The API are procedures that exist in files on your PC which you can call from within your VB program - and there are thousands of them!.
Programming on Purpose Visual Basic / General Development
This tutorial is about detailed design. To illustrate the kinds of things you need to think about when designing an application, we'll be looking at the design and construction of a window-management scheme, perhaps the most fundamental part of any Windows program.
Using the Mouse Visual Basic / Miscellaneous
If you're expecting to have to drain your brain to understand VB's mouse support features, then you're going to be disappointed. Using the mouse within a program is actually very simple and in the next ten minutes you'll have been exposed to most of the things you'll ever need to know!.
Polymorphism in VB.NET Visual Basic / VB.Net
Polymorphism is one of the key concepts in Object Oriented Programming. Using polymorphism enables the programmer to design software that is easily extensible which, in turn, prolongs the life of that program.
Error Handling Visual Basic / Error Handling
The bottom line is that all of us make mistakes. VB is pretty clever about finding syntax errors within the IDE, but a number of the possible errors simply cannot be discovered until you try to run the program. This section discusses some of the available error detection and correction techniques.
GPS Monitor Visual Basic / Networking
This program shows how to connect to a GPS receiver (wired or bluetooth via SPP outgoing connection) and decode GSV, GSA and GGA sentences of NMEA protocol, display position coordinates and satellite informations such as signal strength, satellite ID and satellites used for fix.
Proxy on Visual Basic. Tutorial Visual Basic / Networking
The most elementary single-thread Proxy in Visual Basic. In creating this manual we set ourselves the task to develop a minimum program code playing the role of Proxy-server (transmitting information from one port to another).
