The information in this article applies to:
A FoxPro stand-alone executable ignores parameters passed to it if they are preceded by a hyphen, even if the whole expression is enclosed in quotes. The subsequent parameters (if any) are shifted to the left.
Pass the parameters with a different preceding character. Some valid characters are:
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
1. Create a new project by using the File menu.
2. In the project window, choose New; then choose program.
3. In the newly created program window, type the following code:
PARAMETERS n1, n2, n3, n4
WAIT WINDOW "Parameters received: " + LTRIM(STR(PARAMETERS()))
WAIT WINDOW IIF(TYPE("n1")=="N", STR(n1), n1)
WAIT WINDOW IIF(TYPE("n2")=="N", STR(n2), n2)
WAIT WINDOW IIF(TYPE("n3")=="N", STR(n3), n3)
WAIT WINDOW IIF(TYPE("n4")=="N", STR(n4), n4)
enter MYFILE.PRG.
type of executable in FoxPro for MS-DOS is irrelevant to this example.
Confirm the subsequent dialogs. When prompted for a name, type MYFILE
each time.
7. Start the executable, passing it four parameters, two of which are
negative numbers.
- In FoxPro for MS-DOS, type the following at the MS-DOS prompt
and press ENTER:
MYFILE.EXE 5 -6 7 -8
- In FoxPro for Windows, choose Run from the File menu, and type the
command line:
MYFILE.EXE 5 -6 7 -8
passed. The subsequent wait windows show that the executable ignored the
second and fourth parameters, and shifted the third parameter to the
left, assigning its value to the second variable. The last two wait
windows generate errors because they have no variable to display.
