Setup Example

VB.NET

Dim StrSize, Ret As Integer

Dim Str As New String("", 256)

Dim DblData As Double

StrSize = 256

DblData = 0.000123

Ret = GpCnvDblToStr(Str, StrSize, DblData)

(Result)

Str : "+0.12300E-003"

StrSize : 11

C

DWORD StrSize, Ret;

char Str[256];

double DblData;

StrSize = sizeof(Str);

DblData = 0.000123;

Ret = GpCnvDblToStr(Str, &StrSize, DblData);

(Result)

Str : "+0.12300E-003"

StrSize : 11

C#

uint StrSize, Ret;

StringBuilder Str = new StringBuilder(256);

double DblData;

StrSize = 256;

DblData = 0.000123;

Ret = gpib.CnvDblToStr(Str, out StrSize, DblData);

(Result)

Str : "+0.12300E-003"

StrSize : 11

Python

StrSize, Ret = ctypes.c_ulong(), ctypes.c_ulong()

Str = ctypes.create_string_buffer(256)

DblData = ctypes.c_double()

StrSize.value = len(Str)

DblData.value = 0.000123

Ret.value = GpibPy.GpCnvDblToStr(Str, ctypes.byref(StrSize), DblData)

(Result)

Str : "+0.12300E-003"

StrSize : 11
