If you need badly to use LoadResData in .Net VB you will have to use the VisualBasic.Compatibility namespace. This also applies to otherΒ VB6 functions that areΒ notΒ supported in .Net VB any more.

Now write Microsoft.VisualBasic.Compatibility.VB6.LoadResData (…) and do whatever you want. If you don’t want to constantly write all the above extremely long line you can go to your project’s properties, select Common Properties->imports on the left window and add the namespace Microsoft.VisualBasic.Compatibility.VB6 into your project. After that you can directly write LoadResData(…)
