运行编制的程序报错，
自己编制了一个程序，运行就弹出对话框报错，连报三个错误，然后又运行正常，各位坛友帮我看一下是程序的问题，还是软件冲突的问题啊？谢谢！
报的错误 是 access violation at address 00407BD6 in moudle "prjmanager.exe" . Read of address 000000F8.
access violation at address 0040BE06 in moudle "prjmanager.exe" . Read of address 000000F8.
access violation at address 00408E0E in moudle "prjmanager.exe" . Read of address 000000F8.
[解决办法]
断点一步一步跟踪一下，就知道了，看看是不是访问了空地址
