### Start Debugging a DLL from the Breakpoints List Window

You can start debugging a DLL from the Breakpoints List window by setting a line breakpoint in that DLL, then issuing the Run command. You can only do this if the compile unit you want to place the breakpoint in was compiled with debug information. To set a line breakpoint in a DLL and then start debugging the DLL, do the following:

1. Open a Breakpoints List window
2. From the Set menu choose Set line
3. In the Line Breakpoint dialog, from the Executable pulldown list choose the DLL you want to debug.
4. From the Source pulldown list choose the source file containing the code you want to debug.
5. In the Line entry field, enter the line number within the source file you want to place a breakpoint in.
6. Click on the Defer breakpoint check box.
7. Issue the Run command by pressing Ctrl+R.
