Does anybody know working thumbnail shell extension written in C# that works on winXP? Also if that doesn’t exists does anybody know how to implement IExtractImage interface and all needed structs in C#? Thanks in advance.
NOTE: It can be done using using .NET 4 and all in one code framework provides samples for it but there is no samples for preVista oses.
I wrote a tutorial on using the pre-vista thumbnail extension interface, IExtractImage. It’s pretty difficult if you start from scratch. I only recommend this if you understand all the issues surrounding shell extensions in managed code.
