I created a file with valentine study ( " .vsp " ) that interfaces with MySQL . The file is called by codide through a webapp created with XOJO . Compile it and I move into the cgi - bin XAMPP but when I call the file does not open by returning to an error as ever ? Help me please :( :(

This error means that file could not be opened.

Let's see, if Xojo can find this file. Can you try, for example:

dim f as FolderItem
f=GetFolderItem("").Parent.Child("Reports").Child("reports.vsp")
If f <> nil And f.Exists Then
MsgBox "Exists: " + f.Name
Else
MsgBox "File doesn't exist"
End If

Hello, Gabriele

Please try to surround suspicious block of code with Try...Catch, as I suggested before:


Try
mProject=new VProject(f)
mProject.Open
Catch e As VException
MsgBox e.Message
End


You should see the reason

HI, Sergey
After various tests , I noticed that the problem occurs when I do I value mProject.

dim f as FolderItem
f=GetFolderItem("";).Parent.Child("Reports";).Child("reports.vsp";)
mProject=new VProject(f)
mProject.Open

I set the permissions as you suggested...

Hello, Gabriele

Valentina plugin uses exceptions to notify the application, if something goes wrong.
Each exception has error number and description text.

It is necessary to catch an exception and handle it some way, so the application will be able to continue processing requests.

You can get exception message and show it to the user, if you just want to know, what's the problem:


Dim r As VReport
Try
r = prj.MakeNewReport( ...
Catch e As VException
MsgBox e.Message
End

MakeNewReport:
mReport=app.mProject.MakeNewReport(3,App.mDataSource_MySql,"SELECT * FROM T1";)

App.mDataSource:

I've just installed XAMPP + V4RB in clean environment on OS X 10.11 and get my Xojo Web app working in CGI mode without any problem:

1) Copied my files into cgi-bin folder:
/Application/XAMPP/xamppfiles/cgi-bin/

* test_cgi_local - it's an application folder
* Reports - folder which contains vsp file

2)
Important to change permissions, because in CGI mode web applications are started by apache.
Currently XAMPP runs apache as "daemon" user.

Execute these commands from Terminal.app to change permissions:
sudo chown -R daemon:staff Reports test_cgi_local
sudo chmod -R 755 Reports test_cgi_local


For testing (or if you don't know the user, etc) you can just allow everything to everyone on that folders:

sudo chmod -R 777 Reports test_cgi_local


3) Pointed browser to localhost/cgi-bin/test_cgi_local/testcgilocal.cgi

**********

So my question is - what error do you get and where do you see it?
In a case of an uncaught exception Xojo shows call stack right in the browser, so it is clearly visible, which method caused an error.

XAMPP is kind of MAMP?

as I know MAMP keeps site in the
Applications /MAMAP/httpdocs/...

Your Web app is copied inside of such path?
Do you copy vsp there also?
Or it is packed inside of web app by Xojo?


2) You can try install VSERVER on THAT machine,
and put vsp into VServer/projects folder

and change a little code to work with vsp via VSERVER.
See Examples.

In this way .. you exclude trouble with "where is vsp?"


3) was you able locate which exactly LINE of your web app cause trouble?
May be using logs, prints, ... debugger,

Checked CGI web apps earlier on OS X - they worked for me with built-in web server, haven't tried XAMPP yet for it.

Is a path to VSP file absolute or relative? Maybe it can't be accessed.

Hello, Gabriele

Have a few questions:

1. What OS do you use?
2. Web application is working when started from Xojo, right?
3. Is XAMPP located at the same computer, where you compile a web application?
