Hi,

I am trying to put this html/javascript code into c# webbroswer control but it shot on script error.

This is the javascript code:

and this is what I wrote in my c# form init function:

webBrowser2.AllowNavigation = true;

webBrowser2.AllowWebBrowserDrop = false;

webBrowser2.IsWebBrowserContextMenuEnabled = false;

webBrowser2.WebBrowserShortcutsEnabled = false;

webBrowser2.ObjectForScripting = this;

webBrowser2.DocumentText =

" " +

"" +

"";

if someone can help, it would be great

thanks

You have missed a closing bracket for script tag before var loser...

Sorry this s just a google answer
The SendKeys class has been updated for the .NET Framework 3.0 to enable its use in applications that run on Windows Vista. The enhanced security of Windows Vista (known as User Account Control or UAC) prevents the previous implementation from working as expected.
The SendKeys class is susceptible to timing issues, which some developers have had to work around. The updated implementation is still susceptible to timing issues, but is slightly faster and may require changes to the workarounds. The SendKeys class tries to use the previous implementation first, and if that fails, uses the new implementation. As a result, the SendKeys class may behave differently on different operating systems. Additionally, when the SendKeys class uses the new implementation, the SendWait method will not wait for messages to be processed when they are sent to another process.
If your application relies on consistent behavior regardless of the operating system, you can force the SendKeys class to use the new implementation by adding the following application setting to your app.config file.

To force the SendKeys class to use the previous implementation, use the value "JournalHook" instead.

Hi,

it doesn't work, i tried few combintions but not working. Never mind, what I have is working good for me.

BTW, I am trying to send keys to this widget using button without typing on it but it does what I send only when I click on the webbroswer and after that I need to click twice on the button in order to be done.

This is the button code: (I have also tried sendwait method - same behavior)

webbrowser.select();
sendkeys.send ("DGX");
sendkeys.send("{ENTER}");

do you have any idea how to solve this?

Thanks

Hi,

It seems that if I insert the html to file and open in browser it works but in visual stodio with webbrowser control it doesn't work, don't know yet

I save the path to html file on my desktop and put it as url in the webbrowser and it is working.

another way I learn on the fly ...

thanks

Hi,

It doesn't show, it just doesn't show nothing on the webrowser.

if you can copy your webBrowser2.DocumentText here it would be great

Thanks

Now I took from other site this widget script and put it on my webbrowser but it doesn't show nothing. This is the code from the site:

and this is what I wrote:

webBrowser3.AllowWebBrowserDrop = false;
webBrowser3.IsWebBrowserContextMenuEnabled = false;
webBrowser3.WebBrowserShortcutsEnabled = false;
webBrowser3.ObjectForScripting = this;

webBrowser3.DocumentText =
""+
"";

Thanks a lot

Hi,

Thanks for your respond, I change it - no script errors but I don't see nothing on webbrowser:

webBrowser2.AllowWebBrowserDrop = false;
webBrowser2.IsWebBrowserContextMenuEnabled = false;
webBrowser2.WebBrowserShortcutsEnabled = false;
webBrowser2.ObjectForScripting = this;

webBrowser2.DocumentText =
" " +

You are missing your HTML , head, and body tag

webBrowser2.DocumentText =
" " +
" " +
"" +
""
webBrowser2.DocumentText =
" " +
" " +
"" +
";

Hope it works now
