To debug a DLL using the project for the executable file
From the Project menu, click Settings.
The Project Settings dialog box appears.
Choose the Debug tab.
In the Category drop-down list box, select General.
In the Program Arguments text box, type any command-line arguments required by the executable file.
In the Category drop-down list box, select Additional DLLs.
In the Local Name column, type the names of DLLs to debug.
If you are debugging remotely, the Remote Name column appears. In this column, type the complete path for the remote module to map to the local module name.
In the Preload column, select the check box if you want to load the module before debugging begins.
Click OK to store the information in your project.
From the Build menu, click Start Debug and Go to start the debugger.
You can set breakpoints in the DLL or the calling program. You can open a source file for the DLL and set breakpoints in that file, even though it is not a part of the executable file’s project.
