In a new or existing process View code of the module (or click on the Code Window) and select Tools, Add a Procedure and add a procedure. In the property dialog choose as startup object Sub Main. Pull-down menu, Add module, select the project properties at the end of the Project tab. StartingĪ new project, delete forms and controls, insert a Module using the Project We will only discussĬreating procedures in modules, given the purpose of this tutorial). You create a procedure in a module or form. Pattern: For counter=start To end statements Next. Pattern: Do While expression statements Loop. Note that statements do not require any statement terminators. True-elseif-statements Else false-statements End If Please General pattern: If expression true-statements ElseIf expression You should use help in VB 6.0 to obtain more information You declare arrays as any other variables indicatingĪn upper bound in parenthesis, e.g. Arrays can be of fixed size or dynamic, and single.Variables are defined In between as discussed previously. User defined types use the structure Type typename.( ) remove, respectively, leading and trailing spaces. Trim ( ) to remove both leading and trailing spaces. Strings are either padded withīlanks (if smaller) or truncated (if greater than the fixed lenght). Fixed-lenght strings are defined using *n after the.Strings, (b) defined user type and (c) arrays. Three other cases are important for Web programming: (a) fixed-lenght Variant - any of the above types (default).Boolean - True or False (default is False).Currency (-922 trillions to 922 trillions).Floating point can be declared as Single or Double.Integers can be declared as Integers (- 32,768) toģ2,767) or Long (- 2 millions to 2 millions).Global variables areĭeclare as PUBLIC varname in the Declarations (in the case of Web programming, only modules). As we saw before a project is comprised of modules and forms In general you declare local variables using DIM varname Variables You declare variables taking into consideration their scope: Some VB 6.0 libraries are available for simplifying many of the Web tasks. Finally, functions/subroutines are also easy to create and use. Also good file I/O commands for sequential, random and binaryįiles. VB 6.0 provides easy I/O statements using formsĪnd controls. block statements, if/then/else, do/loop, For/Next, Foreach/Next (no VB 6.0 supports a variety of control structures Integer, long, single, double, currency, string, boolean, date, variant, There are many types of variables in VB 6.0, including

You can download the form and the projectįiles for practice. You set the properties of the form by changing its properties. A menu, toolbar and a toolbox also make the programming taskįorms and Controls (very brief tour).

Windows are also open to help you develop programs, like Forms, Project, Your program by running it and seeing results in the Debug Window. Project requires either a Form of a Main procedure to run. Or project, is a collection of modules, including forms (.frm), Basic code Visual Basic 6.0 (VB 6.0) is installed in the UB labs, but not in the MISLab.ĭevelopment Environment VB 6.0 is a graphical development environment.
