Visual Basic 6.0 問題(急>.<)
有冇人識寫有關Profit and Loss 
要有依幾個point 
-Calculate the monthly profit and loss. 
-Print out on screen the monthly sales report. 
-Print out on screen the monthly purchassing report. 
 
仲有呢 
如果我叫左1個order 
之後我按一個新order 
最後我結算果陣 下出面有個box係顯示我總共叫左幾多個order(姐係張全部叫左概order數目加起黎再顯示比人睇) 
我做果陣正係顯示到最尾果次落order概數目 佢唔識再之前新order果d野加起黎 
唔該>.< |
