Can't run execl() c++ method correctly and have no idea why

coss_cat · 01-20-2013, 04:37 AM

Hello everyone,

I work on a program that involkes at a stage a shell command. My command that i need to involke is this:

openoffice.org3 "macro:///Standard.Module1.findandreplace" file.doc
or
openoffice.org3 file.doc "macro:///Standard.Module1.findandreplace"

... both are correct, run perfect in terminal and do what they should.

My issue is that inside the c++ program i have something like and no matter what i do is a failure:

Code:

void openofficelaunchwithmacro()
{
QString filename=file.doc;
int code=fork();
if (code == 0)
execl("/usr/bin/openoffice.org3"," \"macro:///Standard.Module1.findandreplace\" " ,qPrintable(filename), 0);
...
}

or 

void openofficelaunchwithmacro()
{
QString filename=file.doc;
int code=fork();
if (code == 0)
execl("/usr/bin/openoffice.org3",qPrintable(filename)," \"macro:///Standard.Module1.findandreplace\" ", 0);
...
}

I use Qt 4.7 as devel environment. The reason why I got to this fork()/execl() solution is because i need a code like shoot and forget, meaning i need to start the process and still be able to do what i must in the user interface. If i use system() method instead, the program has to wait until openoffice is closed and like this stalls.
One more thing; does anyone has an idea where can i find libre office writter's macros folder? Couldn't find it with find.

When getting to this part the program does nothing.

Any suggestions?

Thank you.

Hello,

I also tried with QProcess. Same thing:

Quote:

QString program = "/usr/bin/openoffice.org3 ";
QStringList arguments;
arguments <<parameter<<" \"macro:///Standard.Module1.findandreplace\" ";//parameter is the file.doc

No success either

One possible problem are the way the last parameter is specified.

Code:

execl("/usr/bin/openoffice.org3",qPrintable(filename)," \"macro:///Standard.Module1.findandreplace\" ", 0);

This translates into the equivalent shell command:

Code:

/usr/bin/openoffice.org3 <filename> '"macro:///Standard.Module1.findandreplace"'

The " on the macro reference are included as part of the macro reference... and should cause openoffice.org3 to fail as not recognizing what "macro:..." is (quotes would be included in the match).

Thank you jpollard,

I managed to run oo, but now an other thing happens; the BASIC code window opens and i get this error message:
"Basic runtime error. Property or method not found: createReplaceDescriptor"
Searched the web, but nothing really helpful. Any clues?

Regards
