Calling a custom function in the dynamic link library in LoadRunner, writing a very simple example, I think the complex application process should also be almost.
Be a DLL file yourself:
Open the VC, create a new project: project-> Win32 Dynamic-link library method, follow the wizard, select "A DLL That Exports Some Symbols" when selecting the type, and then the VC will open the workspace after completion.
Add a custom function to zltest.cpp, very simple, is the return value.
Int Fun (int X)
{
Return X;
}
Add the following code in Zltest.h:
EXTERN "C" _Declspec (dllexPort) int fun (int x);
Run, generate ZLTEST.DLL and ZLTEST.LIB files in the debug folder.
Copy the zltest.dll file to the folder of the LoadRunner script, add the code in the LoadRunner script:
INT x = 1000;
Int R;
Ret = lr_load_dll ("zltest.dll"); // Load DLL library
RET = fun (x); // Call the custom FUN (INT X) function in the zltest.dll file
LR_output_message ("DLL value =% D", RET); // output function return value
This calls the custom function in the LoadRunner script.
