Tab navigation

I have two tabs open in IE. Tab 1 is active. How can I change the url of Tab 0? I tried IEApp.Navigate, but it seems to change only the active tab.

Thanks,
Neil

Hello Neil,

You need to send a message to the instance of your add-on in that tab, see {the module}.SendMessageToInstance(). You call IEApp.Navigate as part of processing that message. In the code sample below, you'll need to use SendMessageToInstance() instead of SendMessage. See alswo the section Messaging here.


private const int WM_USER = 0x0400;
private const int MYMESSAGE = WM_USER + 1000;
//...
private void adxKeyboardShortcut1_Action(object sender)
{  this.SendMessage (MYMESSAGE, IntPtr.Zero, IntPtr.Zero);  }
//...
private void IEBarModule_OnSendMessage(object sender, AddinExpress.IE.ADXSendMessageEventArgs e)
{
if (e.Message == MYMESSAGE)
{  //... }
}

But if I use SendMessageToAll, in the relative OnSendMessage can I use the IEApp.Navigate? Are there any differences between an IEModule and IEBarModule? I noticed that the OnSendMessage does not have the sender in case of IEModule.

Thanks again.

Yes. SendMessageToInstance sends a message to the specified add-on instance, while SendMessageToAll sends a message to all add-on instances.

They represent different IE extension types: IE add-in and IE Bar. Still they provide a similar set of methods/events.

This event doesn't provide that parameter. In case you need to pass something allowing to identify the module (=the add-on instance) which sent the message, you can pass it in the parameters of the SendMessage method e.g. if every instance of your add-on has an ID (integer), you can cast it to IntPtr and pass it in wparam or lparam parameters of the SendMessage method.

All the SendMessage/OnSendMessage machinery is developed in order to help you deal with many instances of your add-on running in different threads and processes.
