Systemqq

Intel_C_Intel — Wed, 28 Mar 2001 06:54:13 GMT

I tried using systemqq to launch winword, as follows:

l4 = systemqq('winword c:myfile.doc')

Apparently no success, as winword is not launched. However,
l4 is returned as .TRUE.

Was ist los?

winword would have to be in your PATH to make this work.

Have you considered the ShellExecute API routine? You could use it to "open" the document. I have used this many times with great success. It will automatically open the document using the default associated with the file type, including web pages!

Ah yes, the path. Actually, I did use the complete path, but still no luck. I still can't figure out why winword is not launched. However, your suggestion to use ShellExecute is a much better idea, and I will try it later today.

P.. If I weren't already using CVF, I would certainly buy it based on the great support!

If the complete path had spaces in it, you would need to enclose the path in "".

Tried ShellExecute today. Here is the command I used:

i4 = ShellExecute( GetHWndQQ(QWIN$FRAMEWINDOW), "OPEN", "c:2maxents.DOC", " ", " ", %VAL(0) )

i4 = 31 upon return. (No association for this file extension). I'm running all this under Win2000. I checked my associations. Indeed DOC is registered to Word.

What should I do next to figure out what the real problem is?

ShellExecute is a Win32 routine, so all strings must be C strings - for example, "OPEN"C.

Yes, and so my MSDN documentation said. This was my first attempt:

i4 = ShellExecute( GetHWndQQ(QWIN$FRAMEWINDOW), "OPEN"C, "c:2maxents.DOC"C, " "C, " "C, %VAL(0) )

Returned i4 = 2 (File not found).

And my third attempt, assuming that I couldn't pass a null-terminated string in such an implicit way, was this:

str1 = "OPEN"C
str2 = "c:2maxents.DOC"C
str3 = ""C

i4 = ShellExecute( GetHWndQQ(QWIN$FRAMEWINDOW), str1, str2, str3, str3, %VAL(0) )

Returned i4 = 2 as above.

Question remains: Do you have any hints for debugging this?

This works

i4 = ShellExecute( GetHWndQQ(QWIN$FRAMEWINDOW), "OPEN"C, "2maxents.DOC"C, ""C, "c:"C, %VAL(0) )

This does not work

i4 = ShellExecute( GetHWndQQ(QWIN$FRAMEWINDOW), "OPEN"C, "c:2maxents.DOC"C, ""C, ""C, %VAL(0) )

LSD,

Your real problem is the backlash in the -string. "2" is a correct escape sequence in a -string and has the decimal value 2.
You should use a double backlash in the string: "I:2maxents.DOC"I

LKD,

Sorry for the prior message. I misused the Spell Check.

Your real problem is the backslash in the C-string. "2" is a correct escape sequence in a C-string and has the decimal value 2.
You should use a double backslash in the string: "C:2maxents.DOC"C

Thanks Guus, that was EXACTLY the problem!
