  已解决:

  貌似参数类型错误导致闪退

  
  

  在此感谢 qq群大神 : @kio1 提供解决办法和以下源码

  
  

  import win.ui;
  
  /*DSG{{*/
  
  mainForm = win.form(text="aardio form";right=759;bottom=469)
  
  mainForm.add(
  
  button={cls="button";text="打开文件";left=433;top=76;right=625;bottom=122;z=2};
  
  button2={cls="button";text="button2";left=434;top=132;right=626;bottom=178;z=4};
  
  edit={cls="edit";text="edit";left=266;top=30;right=628;bottom=61;edge=1;z=1};
  
  picturebox={cls="picturebox";left=90;top=206;right=400;bottom=436;notify=1;z=3}
  
  )
  
  /*}}*/
  
  
  
  import console;
  
  import fsys;
  
  import fsys.dlg;
  
  
  
  
  
  //重点: 如果没这个打开load就会闪退
  
  import win.ole;
  
  SysAllocString_ = Oleaut32.api("SysAllocStringA","pointer(string psz)");
  
  
  
  //原库dll函数声明
  
  var dll = ..raw.loadDll("\res\ImageWizard.dll");
  
  ImageWizardStartUp = dll.api("ImageWizardStartUp","void()") ;
  
  LoadImageFromFile = dll.api("LoadImageFromFile","INT(pointer FileName, pointer& Image, INT Index)");
  
  
  
  console.open();
  
  
  
  var filename;
  
  var imgHandle;
  
  
  
  mainForm.button.oncommand = function(id,event){
  
      //mainForm.msgbox( mainForm.button.text );
  
      filename = fsys.dlg.open("所有文件|*.*");
  
      mainForm.edit.text = filename;
  
      ImageWizardStartUp();
  
      console.log(filename)
  
  }
  
  mainForm.button2.oncommand = function(id,event){
  
  //路径有中文要进行转译先
  
      p = SysAllocString_(string.fromto(filename,65001,936))
  
      console.log(LoadImageFromFile(p,,0))
  
  }
  
  
  
  
  
  mainForm.enableDpiScaling();
  
  mainForm.show();
  
  
  
  return win.loopMessage();

  上面代码增加了状态输出,当调用getwidth函数的时候发现,提示:未初始化image

  import win.ui;
  
  /*DSG{{*/
  
  mainForm = win.form(text="aardio form";right=759;bottom=469)

  button2={cls="button";text="加载";left=434;top=132;right=626;bottom=178;z=4};
  
  button3={cls="button";text="释放";left=431;top=413;right=623;bottom=459;z=5};
  
  button4={cls="button";text="获取宽度";left=436;top=191;right=628;bottom=237;z=6};
  
  edit={cls="edit";text="edit";left=266;top=30;right=628;bottom=61;edge=1;z=1};
  
  picturebox={cls="picturebox";left=55;top=125;right=365;bottom=355;notify=1;z=3}

  mainForm.show();
  
  
  
  return win.loopMessage(); 
  
  

  显示:

  ok  pointer: 0A39C348

  ImageNotInitialized   0

  
  

  出错的含义,图片未初始化, 但是我已经初始化了啊????

  求解
