I have tested this using Intel Fortran 2020 Update 4 for both 32 and 64 bit targets. #DIALOGS SIMPLY FORTRAN PLUS#means needing a second install, plus creating a way to get the information to and from the external language.Įven if you wanted to create a full-blown Windowing application, there are Fortran libraries available (free and paid) to make it easier.įWIW, I rewrote the Intel example to be self-contained and Fortran 2018-compliant (except for the one line of directive). I do not agree that calling Python or Tcl is any less of a hassle than the 30-odd (not 100) lines it takes to use the Windows API. #DIALOGS SIMPLY FORTRAN HOW TO#!

SAMPLE SOURCE CODE - SUBJECT TO THE TERMS OF SAMPLE CODE LICENSE AGREEMENT, Here is the complete Intel code sample (I can’t get the whole thing to format as code): (Visual Studio is also not required to use the Windows API.) ![]() The code sample from requires some modules (Constant and Toolbar) that they must have created themselves, as those are not part of Intel Fortran. All that is necessary is a compiler that supports the STDCALL calling mechanism (on 32-bit only, not an issue on 64-bit), a declaration of the appropriate derived type, and linking against comdlg32.lib (part of the Windows SDK). It does, however, include predefined declarations that make it easier. I even got asked if I could improve the code/user experience further for Intel Fortran is not required to use the Windows API routines. ![]() The purpose of the program was to measure the surface tension of a liquid drop from a set of images and produce a small text report. As soon as I added the file selection dialog box, they found it much more convincing and easier to use. In the first iteration of the program I had a command-line interface, but the users (fellow scientists and master students), were not that happy to work with it. Recently, I did a project in MATLAB where I used the uigetfile function (“Open file selection dialog box”). While it might be difficult to get it to work across operating systems, a simple file dialog can be a very effective way to bring a program closer to the users. API for file system operations: directory manipulation.Well there is a file system operation module in development (see here) which aims to work across operating systems. Ret=TextOut(iret,100,100+100*i,FileBuf,LEN(FileBuf)) !输出新的字母Ĭoncerning dlgopenfile() and dlgsavefile() or equivalent, I doubt they could be included in the Fortran standard library because it’s too dependent on the operating system.
