VFP中仿MSN的右下角消息提示窗口

1、.VFP中仿MSN的右下角消息提示窗口(转) *!* VFP中仿MSN的右下角消息提示窗口*!* 作者：MEIZIBBSRichardWZP 2006.04.14*!* 调用方法：*!* PopWindows(cFrmCap,cFrmIco,nLayer,nWaitTime,cLblCap,cMess)*!* cFrmCap: C型，窗口的标题*!* cFrmIco: C型，窗口图标，若你程序中使用SET PATH设置了搜索路径，此处可以写相对路径*!* nLayer: N型，窗口透明度，最小值0（完全透明），最大值250（完全不透明）*!* nWaitTime: N型，等待时间。以毫秒为单位

2、，1秒=1000毫秒*!* cLblCap: C型，显示信息的标题*!* cMess: C型，要显示的信息*!* 适用VFP版本：VFP6、7、8、9*!* 适用WINDOWS版本98、2K、XP、2003SER*!* 调用示例：popWindows('提醒','E:gdm_accessPRGICOmy computer.ico',200,2000,'提醒','欢迎使用'+CHR(13)+'小小设计')*!* 说明：*!* 1、这只是一个思路，你可以通过此思路创建自己的消息窗口，比如加入图片*!* 2、因为调用的顶

3、层表单，且设置了透明度，所以不会影响你的基本界面*!* 3、若不希望窗口自动消失，可设置“等待时间”为0；*!* 4、当然，当窗口的EDITBOX获得焦点时，也不会自动消失的（单击表单后消失）*!* 5、编译为EXE为200K，占用内存300K以下（我用DELPHI编译后50K，占用内存30K，为何如此差距？）FUNCTION popWindowsLPARAMETERS pcCaption,pcIco,pnLayer,pnWaitTim,pcMesCap,pcMes,plMaxButt,plMinButtPUBLIC oFrmPopWindowoFrmPopWindow=NEWOBJECT(&
