InstallAware

Hi all,

I was wondering if it is possible to call a dll function which will allow me to read information stored on Hasp security keys/dongles? For example, how to get the serial number from the key.

Thanks in advance,
Sinead

As long as hasp company provides a native Win32 Dll to call the function from, yes it can be done.

Hi,

I have the following dll functions which I need to call, they are declared as follows:

extern "C" __declspec(dllexport) int CheckRegCode(int Version, char *UserName,char *RegCode,int& Result,int &Status);

extern "C" __declspec(dllexport) int IsDongleBitSet(int Bit,int& Result,int& Status);

extern "C" __declspec(dllexport) int GetDongleStatus(int& Status);

However when I try to reference these in a simple InstallAware project I am getting FUNCTIONNOTFOUND.

I use the following code in my InstallAware project:

Set Variable ReturnCode to Test
Set Variable Result to
Call DLL Function DmmDon.dll->GetDongleStatus (get result into variable ReturnCode)
MessageBox: $ReturnCode$

I read a post on this forum which recommended putting the dll into the support files section, which I have also tried but to no avail. (Note: when I put the dll into the support files section I then use
Call DLL Function $SUPPORTDIR$\\DmmDon.dll->GetDongleStatus (get result into variable ReturnCode)

Any ideas on why this isn't working?

Thanks,
Sinead

please post the Call Dll Function line just by copying it, not as text so we can see if you are calling it right

Hi,

On further inspection into my dll code, I saw that to call the functions I need to prefix with an underscore '_'. I am using the C calling convention.

All is working fine now. Thanks for your reply.
