关于控件属性设置，我觉得这个结果很奇怪
一个面板上有八个文本控件，分别显示四个轴的位置，速度，显示时我分开显示，即按一个显示位置的键时显示四个位置控件，按显示速度键时显示四个速度控件，属性设置部分程序如下：int CVICALLBACK posdisplayerfun (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
{
switch (event)
{
case EVENT_COMMIT:
SetCtrlAttribute (tempPanelHandle, TOPERATE_X_position, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_Y_position, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_A_position, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_B_position, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_XAXISVEL, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_YAXISVEL, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_AAXISVEL, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_BAXISVEL, ATTR_VISIBLE, 0);
break;
}
return 0;
}
int CVICALLBACK Jogparamdisplayerfun (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
{
switch (event)
{
case EVENT_COMMIT:
SetCtrlAttribute (tempPanelHandle, TOPERATE_X_position, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_Y_position, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_A_position, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_B_position, ATTR_VISIBLE, 0);
SetCtrlAttribute (tempPanelHandle, TOPERATE_XAXISVEL, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_YAXISVEL, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_AAXISVEL, ATTR_VISIBLE, 1);
SetCtrlAttribute (tempPanelHandle, TOPERATE_BAXISVEL, ATTR_VISIBLE, 1);
break;
}
return 0;
}
可是运行时报错了
531, 70 Illegal expression.
531, 72 syntax error; found 'integer constant' expecting ')'.
531, 72 Insufficient number of arguments to `SetCtrlAttribute'.
531, 72 syntax error; found 'integer constant' expecting ';'.
531, 87 syntax error; found ')' expecting ';'.
531, 87 Illegal statement termination.
很奇怪的是报错的只有设置显示速度的那几条语句，显示位置的很正常，为什么一样的控件，一样的语句，结果不一样呢？
<P>好着的阿</P><P>我把你的代码调试了一下</P><P>显示很正常</P><P>是不是什么地方犯了低级错误了</P> <P>呵呵，不好意思，这个问题已经解决了，我改了源程序但是头文件没有重新生成</P><P>我是个新手，让你见笑了</P><P>谢谢你了！</P> <P>我以为头文件只要自己相应的改一下就可以了，原来不行哦，它后面的序号都必须自己生成，不能自己想当然去改，希望各位新手不要犯我这种低级错误。</P><P>看样子我还有很多东西要学哦</P>
