小弟有一事不明,只好向各位请教了,关于 vb 中对windows注册表的操作。
我想在
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run中添加一个键可怎么办呀,我怎么弄都是把 这个键给添加到 HKEY_CURRENT_USER\Software\VB and VBA Program Settings\
去,
很不爽。我的系统是 win 2k(sp3) + vb6.0
我对注册表 的操作用的是 vb 里的 saveSetting() 函数请各位 大虾帮帮小弟吧哦,还有一件事,我做的一个程序 ,刚开始运行的时候占 2m内存,使用句柄数=65,
等打开另一个窗口(form2)后,占3m内存 使用句柄数=112。
等我把form2给 unload 以后, 还是占3m内存 使用句柄数 =111。
这是怎么回事?我不是已经把 form2 给unload 了吗?怎么还赖在内存里不销毁?
请教!
