What is the purpose of Ansi keyword in VB.NET?

Ansi keyword specifies that Visual Basic should marshal all strings to American National Standards Institute (ANSI) values regardless of the name of the external procedure being declared.

Specifies that Visual Basic should marshal all strings to American National Standards Institute (ANSI) values regardless of the name of the external procedure being declared.

When you call a procedure defined outside your project, the Visual Basic compiler does not have access to the information it needs to call the procedure correctly.

This information includes where the procedure is located, how it is identified, its calling sequence and return type, and the string character set it uses. The Declare Statement creates a reference to an external procedure and supplies this necessary information.

The charsetmodifier part in the Declare statement supplies the character set information for marshaling strings during a call to the external procedure.

It also affects how Visual Basic searches the external file for the external procedure name.

The Ansi modifier specifies that Visual Basic should marshal all strings to ANSI values and should look up the procedure without modifying its name during the search.

If no character set modifier is specified, Ansi is the default.

Remarks

The Ansi modifier can be used in this context:

About the Author: Bernard Aybout

In the land of bytes and bits, a father of three sits, With a heart for tech and coding kits, in IT he never quits. At Magna's door, he took his stance, in Canada's wide expanse, At Karmax Heavy Stamping - Cosma's dance, he gave his career a chance. With a passion deep for teaching code, to the young minds he showed, The path where digital seeds are sowed, in critical thinking mode. But alas, not all was bright and fair, at Magna's lair, oh despair, Harassment, intimidation, a chilling air, made the workplace hard to bear. Management's maze and morale's dip, made our hero's spirit flip, In a demoralizing grip, his well-being began to slip. So he bid adieu to Magna's scene, from the division not so serene, Yet in tech, his interest keen, continues to inspire and convene.
