how do I use the AProcess (or LocalProcess) class?
could you put an example? (I didn't really find in the examples how to use it to load the process or the documentation I don't know about)

(I tried to use the routine:

#include <cstdlib>
...
system("C:\\Windows\\System32\\notepad.exe");

but it opens the dos prompt and this is not recommended/or viable)

Dear BetoValle

If you want to open a GUI application like notepad, you do not need to use LocalProcess.

If you want to open a file named "C:\MyFolder\Myfile.txt", just call:

LaunchWebBrowser("C:\\MyFolder\\Myfile.txt")

The software assigned to that file extension will open your file.

Best regards
Iñaki

Hi,

there are 2 situations that involve parameters:

1- a chm file with the topic

2-how i execute jar file?

I tested it directly but it doesn't work LaunchWebBrowser. Is there any way?

C:\\Program Files\\Java\\jre1.8.0_261\\bin\\java.exe
-jar
C:\\Program Files\\spath\\file.jar

See, here is just an idea to include a launchwebbrowser extension in ui sources. I tested it for jar files and it worked now and it's up to you experts to better evaluate this issue.

1) App.cpp line
void LaunchMy(const String& url, const String& p, const String& d)
{
WString wurl = ToSystemCharsetW(url);
WString wp = ToSystemCharsetW(p);
WString wd = ToSystemCharsetW(d); // file.jar directory <---
if ((int64)(ShellExecuteW(NULL, L"open", wurl, wp, wd, SW_HIDE)) <= 32) {
int l = sizeof(wchar) * wurl.GetLength() + 1;
char *curl = (char *)malloc(l);
memcpy(curl, wurl, l);
StartAuxThread(sShellExecuteOpen, curl);
}
}

2) App.h / line 87
void LaunchMy(const String& url, const String& p, const String& d);

3) this work!

LaunchMy("C:\\Program Files\\Java\\jre1.8.0_261\\bin\\java.exe",
"-jar file.jar",
"C:\\Program Files\\pathA\\pathB");

ok, now i also solved the help chm load:

I changed the function to

void LaunchMy(const String& url, const String& p, const String& d, int howshow)
{
WString wurl = ToSystemCharsetW(url);
WString wp = ToSystemCharsetW(p);
WString wd = ToSystemCharsetW(d);
if ((int64)(ShellExecuteW(NULL, L"open", wurl, wp, wd, howshow)) <= 32) {
int l = sizeof(wchar) * wurl.GetLength() + 1;
char *curl = (char *)malloc(l);
memcpy(curl, wurl, l);
StartAuxThread(sShellExecuteOpen, curl);
}
} //howshow: SW_HIDE (0) SW_SHOW (5) SW_SHOWDEFAULT (10)

to work:

LaunchMy("hh.EXE",
"ms-its:FinestFI.chm::/IDH_Topic20.htm",
//or "mk:@MSITStore:file.chm::/IDH_Topic20.htm"
"path of file.chm ie C:\\abc\\def\\ghi",SW_SHOW);

if you want you can close this topic. Thankful.
