use of old DLL's in VB.NET

[Tachyon]

Our company has a lot of selfcreated DLL's but we want to create applications in VB.NET.

Does the use of old DLL's give any big problems?? Does anyone have experience with the use of old DLL's???

Unless you are using weird data structures, calling straight DLLs works fine. You can even re-use your old DECLARE statements from VB6 (the mail thing I've found is that you need to make sure you change all the declarations to use Integer where VB6 used long - a VB.NET integer is the same size as a VB6 long).
