通过脚本打开颜色选择窗口/使用Windows choosecolor dll<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

我想通过脚本打开JMP颜色选择窗口。应返回用户选择的颜色（RGB值）。

所以我想通过脚本打开这些窗口：

这可能吗？到目前为止，我没有找到办法（使用JMP 12.1）。

所以我认为你可以使用Windows DLL。我的问题是我不知道如何使用dll ...

使用JMP脚本指南和语法参考书以及下面提到的Internet页面，我创建了以下代码：

/*user32 = Load Dll( "User32" );user32 << DeclareFunction(    "FindWindowA",    Convention( STDCALL ),    Alias( "FindWindow2" ),    Arg( UInt32, input, "lpClassName" ),    Arg( AnsiString( 200 ), input, "lpCaption" ),    Returns( UIntPtr ));lpCaption = "Script - JMP";hWnd = user32 << FindWindow2( 0, lpCaption );user32 << UnloadDLL();*/dll = LoadDLL("C:\Windows\System32\comdlg32.dll");dll << Declare Function(    "ChooseColorA",    Convention(STDCALL),    Alias("ColorPalette"),    StructArg(        Arg(UInt32, "lStructSize"),        Arg(Int64, "hwndOwner"),        Arg(Int64, "hInstance"),        Arg(UInt32, update, "rgbResult"),        Arg(AnsiString, "lpCustColors"),        Arg(UInt32, "Flags"),        Arg(Int64, "lCustData"),        Arg(Int64, "lpfnHook"),        Arg(AnsiString, "lpTemplateName"),        update    ),    Returns(Int8));selected_color = 5;hwnd = 0;size = 36    ;result = dll << ColorPalette(    size,        // lStructSize    hwnd,        // hwndOwner    0,            // hInstance    selected_color,    // rgbResult    "",            // lpCustColors    2,            // flags;    2 = show all colors    0,            // lCustData    0,            // lpfnHook    ""            // lpTemplateName);show(result);dll << UnloadDLL();

此代码不起作用，不显示颜色选择窗口，但调用ColorPalette函数的结果始终为零。

我认为一个问题是我不知道'lStructSize'的正确值。我尝试了从1到10000的每个值，没有任何变化。所以很明显我的代码中有更多错误（正如我所说，我不知道如何使用dll）。

anybode可以帮忙吗？

这里有一些VBA代码可以在MS Excel中工作（我在互联网上找到了稍微修改过的代码）。我试着在JMP中做同样的事情。

Re：用脚本打开颜色选择窗口/使用Windows selectcolor dll

我有同样的要求。 谢谢你的示例代码。 我修改了它并通过了JMP 12中的测试。

这是我的剧本 

ChooseColor = Function( {intColor, flags=3},
 {Default Local},

 If( Host is( Windows ),
  dll = Load DLL("C:/Windows/System32/Comdlg32.dll",  Quiet );
  dll << Declare Function( "ChooseColorW", Convention(STDCALL), Alias("PickColor"),
   StructArg(
    Arg(Int64,  "lStructSize"),
    Arg(Int64, "hwndOwner"),
    Arg(Int64,  "hInstance"),
    Arg(Int32, "rgbResult"),
    Arg(AnsiString(64), "lpCustColors"),
    Arg(Int64,  "Flags"),
    Arg(Int64, "lCustData"),
    Arg(Int64, "lpfnHook"),
    Arg(UnicodeString, "lpTemplateName"),
    Update,
    "CHOOSECOLOR"
   ),
   Returns(Int32)
  );

  lStructSize = 72;
  hwndOwner = 0;
  
  lstRGB = As List( ( Matrix( Color To RGB(intColor) ) * 255 ) );
  hexRGB = Concat(Substr(Hex(lstRGB[3], "integer"),7,2), Substr(Hex(lstRGB[2], "integer"),7,2), Substr(Hex(lstRGB[1], "integer"), 7,2));
  rgbResult = Hex to Number( hexRGB ); 
  lpCustColors = Repeat(Hex To Char( "FFFFFF00" ), 16);
  lCustData = 0;
  lpfnHook = 0;

  intRc = dll << PickColor(lStructSize, 0, 0, rgbResult, lpCustColors, Flags,0,0,"");

  If(intRC == 0, 
   Return(intColor)
   ,
   hexRGB = Hex(rgbResult, "integer");
   Return( RGB Color( Hex to Number(Substr(hexRGB,7,2)), Hex to Number(Substr(hexRGB,5,2)), Hex to Number(Substr(hexRGB,3,2) ) ) );
  );

  dll << Unload DLL();
 );
);
