I collected my notes about getting msvc4's setup running under Wine at http://www.kegel.com/linux/winelog.html I now have wordpad reading .wri files properly under Wine (needed for the "STL" button). The next problem is that the setup program does ShellExecute(..., "explorer.exe", ".", ...) to pop up an explorer window.

Well, wine has Winefile, but not explorer.exe. It looks like the path of least resistance is for me to write a trivial little explorer.exe that just cd's to argv[1] and fires up winefile (which always operates on the current directory). I've written it, and I expect when I add the needed registry entry, it'll make msvc4's setup's "explore this cd" button work fine.

Anyone think that'd be a bad thing to put into the Wine tree? - Dan

Hi!

I attached a small explorer like programm onto http://bugs.winehq.com/show_bug.cgi?id=1227 maybe we could port it into c code and include it into wine. It might be a good starting point to start a full featured explorer like programm. (And it's a good test for built in shell32)

I think that Dan has a shorter and better solution. After all its easier to fix the existing code and write a wrapper than coding a new program. --- Jürgen_Schmied j.schmied@t-online.de a écrit : > Hi!

OK, then. Here's a patch that makes 'start explorer.exe d:' work (needed by msvc4.0's setup program).

Note that winefile had not in the past been installed in the fake windows area. This patch causes it to be installed there, and indeed under the name 'winfile.exe'. Hope that's ok.

I'm tempted to wait until somebody else agrees that this works before posting it to wine-patches... - Dan
