BUG: _WSetPort Function in LCK Does Not WorkID: Q108334 The information in this article applies to:
SYMPTOMSThe _WSetPort() function of the FoxPro Library Construction Kit (LCK) does not return the correct WHANDLE to the previous window on the Microsoft Windows platform. RESOLUTIONTo work around this problem, use _WGetPort(), which returns the correct value. To correct the sample code in the "More Information" section below, replace the following line fpdt=_WSetPort(wh); with: fpdt=_WGetPort(); =_WSetPort(wh); STATUSMicrosoft has confirmed this to be a problem in FoxPro 2.5, 2.5a, 2.5b, and 2.6 for Windows and in the FoxPro 2.5 Library Construction Kit. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available. MORE INFORMATIONSteps to Reproduce Problem1. Using any compiler, build a FoxPro link library (.FLL) file from the following C code: #include <PRO_EXT.H> void FAR One () { WHANDLE wh,fpdt; wh = _WOpen (1,1,10,50,CLOSE,USER_SCHEME,(Scheme FAR *)0,WO_PANELBORDER); _WShow(wh); fpdt = _WSetPort (wh); _Execute ("Wait"); fpdt = _WSetPort (fpdt); /* Restore FoxPro Desktop */ _WClose (wh); } FoxInfo myFoxInfo[] = { {"ONE",(FPFI)One,CALLONLOAD,""} }; FoxTable _FoxTable = { (FoxTable FAR *)0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo }; 2. In FoxPro for Windows, execute the following commands: SET LIBRARY TO <.FLL created in step 1> ? "Hello" && This should cause a GP Fault NOTE: In FoxPro version 2.6, a "Resource Manager Internal Consistency Error" message will be displayed just prior to the GP fault.
