Avoid loading dlls? 2

[Robertio]

Our program uses 3rd party postcode software to retrieve addresses. The problem is that we support multiple pieces of postcode software, and when the program starts up it auto checks for the dlls (the declarations are in definition units) and won't start if it can't find them.

This is inconvenient as the users are likely to only have one of these postcode programs on their machine, so we would have to ship the dlls for each program just so our program can start up.

Anyone know of a way of getting around this problem, by only looking for dlls once the program is up and running? (at which point we will know which dlls we should try to load)


Thanks

Load the DLL at runtime instead - dynamic dll loading.

Ever got the feeling you spoke too soon?

Following the above links instructions the program falls over when the dllfunc(parameters) is called it seems to be calling mov [ebx],ax thousands of times, resulting in an access violation.

The routine I am calling in the dll is a function, but that appears to be about the only difference, any ideas?
