wintypes.dcu not found and code completion stops working

Question

I'm getting the error: wintypes.dcu not found several times a day in the Delphi 2009 IDE, after this error code completion stops working, also I can't open any unit's source code with Ctrl + Click, then I have to reopen the IDE to fix it.

Anyone has a clue about what can be causing this?

The only IDE extension I have installed is GExperts.

Answer 1

Why wintypes.dcu cannot be found any longer, I do not know. But the other two are obvious follow up errors: if Delphi cannot compile the code due to syntax errors (and a missing file is considered a syntax error), it stops code completion and cannot locate source code any longer using Ctrl + Click.

Answer 2

wintypes.pas and winprocs.pas has been replaced with windows.pas (since a long time). You should use Unit Aliases to replace all wintypes with windows.

Answer 3

You must be still using the ancient (pre-Delphi 2) names for what is now the Windows unit. I recommend that you search and replace all your uses lists and replace WinTypes and WinProcs with Windows.

Alternatively, you can make sure you have "WinTypes=Windows" and "WinProcs=Windows" in the Unit Aliases section of your project options, but still, after all these decades, I'd move on to the 32-bit world! (16-bit being the prime limitation that meant WinTypes and WinProcs were two separate units.)

Answer 4

this is a really evil problem. i believe i've had years of very poor code completion functioning because a 3rd party package mentioned these units. very, very expensive problem for me.

Answer 5

I have the same problem. In my project there is no reference to WinTypes or WinProcs. I use only Quickreport5 as a 3rd party. Any suggestion?

Answer 6

Do you use the Decision Cube component? So look for references on the unit MXQEDCOM.pas in your sources.

On BDS 2006, is the only reference for Wintypes and Winprocs I found.

By the way, make sure that the Unit Aliases included the values that Barry Kelly wrote.

Answer 7

Örjan Jämte is right. I looked for WinTypes and WinProcs, and they are not found. However, Windows.pas can be found in the following directory of Delphi 5.

Program Files\Borland\Delphi 5\Source\RTL\Win.

Thanks!

Open Project - Options, Delphi Compiler ,into Unit aliases insert:

WinTypes=Windows;WinProcs=Windows;DbiProcs=BDE;DbiTypes=BDE;DbiErrs=BDE
