加载外部模块

问题描述：

客户端，用LoadLibrary的方式调用Lang.dll，dzhwt.dll 但dzhwt.dll 在VS中的pdb文件无法加载

1. 管理员身份启动windbg

2.symbol file path:设置正确的pdb路径

     srv*D:\windbgSymbols*http://msdl.microsoft.com/download/symbols;D:\Source\dzh2\bin\pdb

3.open excutable

    选择 dzh2pri.exe,填好命令行参数 main=$,并启动

4.启动程序，到Wt界面    

5.中断，查看当前哪些模块已经加载pdb

6.加载需要的模块 ld dzhwt,ld Lang

  7.Open Source File 加断点

8. 继续运行到断点命中,命中后为紫色

9.看堆栈，KB ,K20B

查看PDB是否是匹配

!itoldyouso dzhwt D:\Source\dzh2\bin\release\dzhwt\bin\dzhwt.pdb

 

总结:

1.设置pdb 路径要正确

2.用ld 加载需要的模块，执行完成后pdb会加载进去

3.用open Source file 打开需要加载断点的源文件

4.加断点

5.k20B 显示全堆栈
