[求助]问一个存储文件的问题
要怎么样存储文件可以使得后来的数据不覆盖以前的数据???我做的第二次存储时就会覆盖第一次的数据,要用什么方法存储才行??? <a href="http://www.cpubbs.com/old_bbs/dispbbs.asp?BoardID=4&replyID=23309&id=12417&skin=0" target="_blank" >http://www.cpubbs.com/old_bbs/dispbbs.asp?BoardID=4&replyID=23309&id=12417&skin=0</A> 恩`~~感谢兄台了~~~试验去~~~ 请问是在write to spreadsheet file前设定还是在write ti text file前设定?能不能给一个实例我看一看?
我现在连接图是这样的
<img src="attachments/dvbbs/2006-5/20065279443424029.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/2006-5/20065279443424029.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /> 还是不了解怎么连接Set File Position~~~附图上来~~~帮我看看要怎么连吧~~~多谢了~~~
<img src="attachments/dvbbs/2006-5/200652517543154161.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/2006-5/200652517543154161.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /> Set File Position这个节点有一个输入端子叫做from(0:start),用鼠标对着它右击,CREATE-->CONSTANT,这样就出来一个常量,从里面选择end就是最后面了! 我是这么选择的啊~~~但是还是会覆盖掉文件~~~是不是那个write to text file的问题啊?还是我连线有问题???我前面放上的那个图片帮我看看该怎么连把~~~ <P>你在写文件前先设定这个!</P>
