Bug #: 34850
           Summary: Improve commctl32 TaskDialogIndirect stub to show
                    "content" part in task dialog box (more detailed error
                    messages for various apps/games)
           Product: Wine

Hello folks,
this is a bug split off from bug 34008 ("Bioshock Infinite won't start (needs
D3D11CreateDevice implementation to support at least D3D_FEATURE_LEVEL_10_0)")
The bug reporter complains that the reason for the error can't be seen in
message box Wine creates (as substitute for task dialog):
--- quote ---
Bioshock Infinite shows an empty message box on launch and closes after
pressing OK button. Nothing else is shown. After making a dirty hack in
commctrl.c (replaced pTaskConfig->pszMainInstruction with
pTaskConfig->pszContent) I can see the messagebox saying that I should have
DX10/11 compatible hardware and DX11 runtime: http://i.imgur.com/OxHDoKI.png
--- quote ---
This is actually true and I've also seen this for other apps that make use of
TaskDialogIndirect.
Wine currently only uses "pTaskConfig->pszMainInstruction" for display which
might not contain the essential information.
Various apps put the real info in "pTaskConfig->pszContent".
