TWIAV - Tips & tricks

On this page you will find some MapBasic code samples, both the program source and the compiled application. Everything on this page is offered "as is" without warranty of any kind, either expressed or implied, including limitation warranties of merchantability, fitness for a particular purpose, and noninfringement.

Unless otherwise stated MapBasic 9.0 has been used to compile the files - this means that the MBXs offered here will only run with MapInfo Professional 9.0 or higher. If you want to use the tools with another (an older) version of MapInfo Professional, you will have to compile the tool using the relevant version of the Mapbasic compiler.

The goal of this project is to provide some examples of how to use certain MapBasic functionality - not to offer full-blown applications. The applications below each focus on one 'trick'. You can study the source, modify it to suit your needs and implement it in your own apps.

The following code samples are available here:

• C# Sample Code - convert a Date value to a Long Date string

• Context Menu Sample Code - add a new menu item to a context menu

• CreatePoint Sample Code - import a txt file and create points in one step

• Custom Functions - create a custom function in MapBasic

• Date Functions Sample Code - use Date functions in SQL Statements

• DrawMode DM_CUSTOM_POLYGON Sample Code - a ToolButton to create custom polygons

• EventHandler Sample Code - use the event handlers WinFocusChangedHandler and WinClosedHandler

• Layout Sample Code - use the Layout statement in your MapBasic application

• Modular Programming Sample Code - an example on how to set up your own project

• MultiListBox Sample Code - use a MultiListBox control in your MapBasic application

• SearchPoint Sample Code - use the SearchPoint() and SearchInfo() function in your MapBasic application

• Thematic Mapping Sample Code - use MapBasic to create a ranged thematic map

This application demonstrates how to set up a MapBasic project consisting of several modules. The actual application - showing current date and current time - is not that exciting at all. It is the source files you should be after: Project.mbp ProjectUI.mb, Functions.mb, ModuleOne.mb and ModuleTwo.mb Project.def You can compile the source files (*.mb) to become object files (*.mbo) and you can link the object files to become an executable application file (*.mbx). This little app is purely meant to be an example on how to set up your own projects.

In the document below you will find a description of the building blocks of a project:  TWIAV_TIP_MB003.pdf: Modular Programming in MapBasic Please see the file below for Project.mbp, ProjectUI.mb, Functions.mb, ModuleOne.mb, ModuleTwo.mb, Project.def and Project.MBX:  Modular Programming.zip

If you are using Notepad++ to develop your MapBasic applications, you can configure your text editor to compile all object files, link the project file and run the resulting application, all with one mouse click or keystroke. More information can be found here.

In this application a custom function is used. This function - LongDate() - converts a Date into a string with weekday and month. In this document you will find description of how to create and use a custom function in MapBasic.

More code samples will follow...;-)
