#47 hwg_ShellExecute() doesn(t work anymore under Linux

[Aupeix Alain]

Hi,
In my programs, I allow to use the default browser or another browser using a variable (cBrowser)

When this variable isn't set (cBrowser=""), I use hwg_ShellExecute() which uses the default browser, when I want to use another browser than the default, I set this variable.

Since a few time (I don't know exactly when), hwg_ShellExecute() doesn't work anymore, and I must set cBrowser to make it work

Here is my test

if cBrowser == ""
hwg_ShellExecute(chr(34)+curl+chr(34))
else
run(cBrowser+" "+curl+" > /dev/null 2>&1 &")
endif

Can somebody repair this function ?

Hello Aupeix,
i use the function "hwg_RunApp()" successfully on Windows and LINUX for starting GUI programs asynchronious. It seems to be, that hwg_shellexecute() is outdated (analyse it, if i have time).
I appended a sample of my app "CLLOG".
I hope, this helps.
Please give feedback, if you have success or not.

Hi, Wilfried,

Thanks for your answer.

After some tests, I find that hwg_ShellExecute() works correctly, except for to types of links with google :

https://www.google.com/maps/place/@45.5858333333,0.758888888889,21060m?hl=fr

http://maps.google.com/maps?ll=45.5858333333,0.758888888889&spn=0.1,0.1&t=k&q=45.5858333333,0.758888888889&hl=fr

I don't understant why it fails.

I didn't know hwg_RunApp( cCommand [, nFlag] [, lAsync] ) ).
What are the purpose of the two last params ?
I suppose the last allows to wait or not the end of cCommand execution, but I don't understand the purpose of the second param ...

Thanks

Hello Aupeix,
because i am very busy, could you do me a favour:
Can you post as an attachment ("Add attachment") a simple sample program with a mini menu ?
(I think the sample of browser usage is a very good template for the community).
Please add the the copyright header of another HWGUI sample program, so that i can
commit it under "samples/gtk_samples" after bugfixing.
I have a suspicion what your problem causes. I'll test it under UBUNTU16/AMD64
with the Firefox browser.

In the next few days i will complete the documentation of the function "hwg_RunApp( )".

Hi Wilfried,

The problem is related to my code, now it works.
I first tried, before posting this bug, to add chr(34) around curl, because I saw that there were spaces at this end of the variable cgoogle
I then use strtran to remove spaces (it was better to use trim())
Now, with this code, removing chr(34), it works
~~~
cgoogle:="http://maps.google.com/maps?ll~~$1$,$2$&spn~~0.1,0.1&t~~$3$&q~~$1$,$2$&hl~~fr"
curl= strtran(strtran(strtran(strtran(cgoogle,"$1$",clat),"$2$",clon),"$3$",ccarte),"~~","=")
curl=strtran(curl," ","")
if withsource
qout(curl+chr(10))
endif
if cBrowser == ""
hwg_ShellExecute(curl)
else
Close_db()
run(cBrowser+" "+curl+" > /dev/null 2>&1 &")
Open_db()
endif~~~

Sorry for this erratic bug report :(
You can obviously close it
