新手求教!!!!!!1
<P>我想调用一个DA卡的dll,不知道怎么做,我胡乱弄了一个,果然不行,求教大侠!多谢DA的两个函数前面一个是打开设备,后面一个是输入数据,全都是通过一个struct实现的
struct定义如下,我感觉我的数据传递有问题,
struct ZT_PCIBOARD
{
long lIndex; /* PCI卡索引值,该值在安装时被系统分配*/
HANDLE hHandle; /* PCI卡的操作句柄(只有涉及中断时才用)*/
short nCh; /* 通道号*/
longlData; /*输入输出数据变量*/
long* plData; /*输入输出数据指针*/
longlCode; /*设备控制字,具体含义见函数说明*/
};</P>
<P> 下面是一个截图</P>
补截图!!!<img src="attachments/dvbbs/2005-8/20058231274830.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-8/20058231274830.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
