I am trying to write my first VFP MTS DLL and it's giving me quite a bit of trouble. I have written several VB components and seemed like I knew what I was doing, but know I don't know. I searched the archives and didn't find anything to really help me. I have updated my developer computer with VS6SP3 and now can build single and multi use DLL's, when I build a multi for use with MTS and try to import the new component is gives my a long error about "One or more DLLs appear to be corrupt...". If I build it for single use, it imports fine, but doesn't create an exe when I export the package. Therefore when I create the object on my developer machine it doesn't seem to use MTS. I don't have VFP loaded on my MTS server and don't know if I need to. Any help or ideas? TIA.
