Dear R-devel,
I would like to launch the Rgui.exe from a Fortran console application (we will call this FortranCon.exe), that I have written myself. To do this, I send the command line "C:\Program Files\R\R-X.X.X\Rgui.exe" (where X.X.X is the version number) as an argument to the Windows API function CreateProcess (see http://msdn.microsoft.com/en-us/library/ms682425(VS.85).aspx) I use the createprocess command because I want the Rgui.exe and the Fortran console application to run in parallel. I have done this before with other executables (e.g. Tinn-R.exe, textpad.exe) and there hasn't been a problem. But with the current version of R(v2.9.1), there is a problem. The problem is that after Rgui.exe is launched by FortranCon.exe, the console window for FortanCon.exe does not close properly when it finishes running. I have to manually close it, by clicking on the topright X on the window. When I do this the Rgui.exe window also closes - which again is different to normal, and then the Windows EndProgram dialog comes up and asks me whether I wish to close FortranCon.exe I have experimented with different versions of R, and this problem only occurs in R(>=v2.7.0) If I launch Rgui.exe for v2.6.2, then the FortranCon.exe window closes automatically when it finishes and the Rgui.exe window remains open - this is the behaviour I expect and want to happen. Indeed, this is what usually happens If I launch other executables using the CreateProcess function. This error does not occur if I launch Rgui.exe from a Fortran windows application. (as opposed to console application) I am running R on Windows XP (Service Pack 3) 32-bit (I have also found the problem occurs using 64-bit Windows XP). The FortranCon.exe is complied and linked by Intel Visual Fortran IVF11.1.035 and Visual Studio 2008. So my query is. What has changed in the R Windows interface from v2.6.2 to v2.7.0 to cause this problem. I had a look at the CHANGES for R2.7.0 and I couldn't see anything the instantly could cause this problem. Any help on this matter is greatly appreciated. The ability to launch R from a Fortran application is important for the usability of the RFortran software library (www.rfortran.org <http://www.rfortran.org/> ) that we are developing.
