MxDrawXCustomFunction::Mx_SetSysVar 方法

设置系统变量.

IDL

static BOOL Mx_SetSysVar(CString sVarName, Value);

参数

参数	说明
CString sVarName	系统变量名
Value	需要设置的值。

成功返回TRUE.

备注

例如: VB 设置系统变量DYNINPUT值为0

Dim param As MxDrawResbuf
Set param = New MxDrawResbuf
param.AddString "DYNINPUT"
param.AddLong 0, 5010 '5010 = RTLONG
MxDrawX1.CallEx "Mx_SetSysVar", param

例如: 设置图层

        Dim param As MxDrawResbuf
        Set param = New MxDrawResbuf
        param.AddString "CLAYER"
        param.AddString "图层1", 5005 ' 5005 = RTSTR,代码是一个字符串类型的值
        MxDrawX1.CallEx "Mx_SetSysVar", param

设置线型例如:

        Dim param As MxDrawResbuf
        Set param = New MxDrawResbuf
        param.AddString "CELTYPE"
        param.AddString "DOT", 5005 ' 5005 = RTSTR,代码是一个字符串类型的值
        MxDrawX1.CallEx "Mx_SetSysVar", param

例如:

设置线型设置颜色.
        Dim param As MxDrawResbuf
        Set param = New MxDrawResbuf
        param.AddString "CECOLOR"
        param.AddLong 255, 5010 ' 5010 = RTLONG,代码是长整型变量的值,255是RGB组合值。
        MxDrawX1.CallEx "Mx_SetSysVar", param

例如: 设置栅格，和栅格距离

        // 打开栅格捕捉
        axMxDrawX1.SetSysVarLong("GRIDMODE", 1);

        // 设置捕捉间距
        MxDrawResbuf param    = new MxDrawResbuf();

        MxDrawPoint ptSNAPUNIT = new MxDrawPoint();
        ptSNAPUNIT.x = 500;
        ptSNAPUNIT.y = 500;
        param.AddString("SNAPUNIT");
        param.AddPointEx(ptSNAPUNIT,5002);

        axMxDrawX1.CallEx("Mx_SetSysVar", param);

例如:

修改图纸的字符编码
     MxDrawResbuf param = new MxDrawResbuf();
     param.AddString ("DWGCODEPAGE");
     param.AddString ("ansi_936");
     MxDrawApplication app = new MxDrawApplication();
     app.CallEx("Mx_SetSysVar", param);
