Hello, PrathyushaCH
To call a method from an imported DLL in TestComplete using C#, you'll need to ensure that you correctly define and invoke the method. Here’s a structured approach to help you access the NavigateTo method from Core.dll.
Step-by-Step Guide
Define the DLL: Make sure you properly define the DLL and the function signature you intend to call.
Load the DLL: Ensure you load the DLL correctly. Use the DLL.Load method to reference the DLL.
Define the Function: You need to define the function you want to call from the DLL correctly. The parameters and return types must match the definitions in the DLL.
Example Code
Here’s an example that outlines how to do this:
function callDll() {
// Load the DLL
var lib = DLL.Load("C:\\auto\\ExternalLibraries\\Core.dll");
// Check if the DLL was loaded successfully
if (lib == null) {
Log.Error("Failed to load DLL");
return;
}
// Define the NavigateTo method from the DLL
var navigateTo = DLL.DefineFunction(lib, "NavigateTo", vt_string, [vt_string]); // Adjust parameter types as needed
// Call the NavigateTo method
var result = navigateTo("YourParameterHere"); // Replace with actual parameter
// Log the result
Log.Message("Result from NavigateTo: " + result);
// Unload the DLL if necessary (optional)
DLL.Unload(lib);
}
Key Points:
DefineFunction: Make sure that the function signature matches what is defined in the DLL. The types (vt_string, etc.) need to be accurate.
Parameter Types: Update the vt_string in the DefineFunction method with the correct parameter types according to the function definition in Core.dll.
Error Handling: Always check if the DLL is loaded successfully and handle errors gracefully.
Logging: Utilize logging to check if your calls are successful and to debug issues.
Debugging Tips:
Ensure that Core.dll is accessible at the specified path.
Verify that the NavigateTo method exists in the DLL and that its signature matches what you're trying to define in TestComplete.
Check the TestComplete documentation for any specific notes on using DLLs and calling external functions.
