Use TProcess class from Process unit.

Also the url is bit strange. You probably need a web server installed. Or created one by yourself using FPC faculties.

i used it but there's no result and i used this little code :   

Code: Pascal  [Select][+][-]

1. rundll32 url.dll,FileProtocolHandler localhost/a.html

Step one would be to fill in the comment about errorhandling with code that does something?

Also start is like a separate form of createprocess, that also takes certain parameters to do things (like show window).

Configuring both createprocess with options, AND use start seems to be a bit double.

i just fix it with this :

Code: Pascal  [Select][+][-]

1. comand :='C:\Program Files (x86)\Google\Chrome\Application\chrome.exe 127.0.0.1/a.html';

i want to know how can i start the a.html file in a hidden way that the new tab doesn't appear

Sounds very fishy to me. What are you trying to accomplish?

chrome (and chromium-browser) has loads of command line options. One of them is

Code: Bash  [Select][+][-]

1.  --app=<URL>

<URL> is the path. Chrome will start without toolbars (also known as kiosk mode)
That is probably what you mean.

Also note it is a bit annoying you use the AnsiString windows API. In your case it is better to use the UnicodeString API: W, not A.
There is - a lot - more wrong with youtr code, but start here. You will see that  --app=<URL> does what you want.

Looks like you need to start a new browser window, so ...

First, as they say above, use TProcess and google for commandline options for chrome, (there are tons of them) particularly those which controls window behavior.

Second, if you want to show contents of local html-file your url should be in a form of

Code: [Select]

path/to/local/file.htmlBut if you want your html to be served by (local, or any other) webserver, your url should look like this:

Code: [Select]

http://localhost/path-as-it-served-by-webserver/file.html

sash, posts crossed. I think he just means kiosk mode, which is like I wrote. Your tip may help too.
[edit]
example for chromium, but also works for chrome that returns your external ip from my servers in kiosk mode:

Code: Bash  [Select][+][-]

1. chromium-browser --app=http://ip.thaddy.com

But that can also be a local path like file://xxxx/a.html
