hi,

I want to know how to convert a code below in C++. Before this i write a code in VB. Can give me a detail code on C++?

Public WithEvents instHtmlButton As mshtml.HTMLButtonElement

Private Function instHtmlButton_onclick() As Boolean Handles instHtmlButton.onclick
MessageBox.Show("OK")
End Function

Private Sub IEModule_DocumentComplete(ByVal pDisp As Object, ByVal url As String) Handles Me.DocumentComplete

Me.instHtmlButton = Nothing

If (Not IsNothing(Me.HTMLDocumentObj())) Then
Me.instHtmlButton = Me.HTMLDocument.getElementById("sampleButton")
End If
End Sub

TQ

Please use the iemodule designer to add IE events. You just need to open IEModule.h in the design mode.

If you don't mind, can give me some examples regarding the design mode in IEModule.h.

Really thanks.

You just need double click on the IEModule.h file and Visual Studion will open the designer.
Another way is right click on the IEModule.h file and choose the View Designer option in the context menu.

Actually, I'm trying to develop Add-on for IE using ADXIE Addon (ADX IEModule) in C++, the idea is like this :

1) When i open my web page (http://localhost/test.html),
IE will show a message box "Welcome".
For that solution, i used DocumentComplete method like following code.

void IEModule_DocumentComplete(System::Object^ pDisp, System::String^ url)
{
if (HTMLDocument()->url == "http://localhost/test.php")
{
System::Windows::Forms::MessageBox::Show("Welcome");
}
}

Problem : When the web page has been loaded, the message box doesn't appear,
because i don't know how to set the event handler for IEModule_DocumentComplete.
When i set the event handler like following

this->DocumentComplete += gcnew
System::EventHandler(this,&IEModule::IEModule_DocumentComplete);

Error : 'void MyIEAddon1::IEModule::IEModule_DocumentComplete(System::Object ^,
System::String ^)' : the specified function does not match the delegate type
'void (System::Object ^,System::EventArgs ^)'

Question : What a correct code to set the event handler for DocumentComplete?

Really need your help on this problem.

TQ.

Hi Putra.

When the web page has been loaded, the message box doesn't appear,
because i don't know how to set the event handler for IEModule_DocumentComplete.

Please do the following:
1. Right click on the IEModule.h
2. Choose the View Designer option.
3. Go to the Properties windows and click on the Events tab.
4. Double click on the DocumentComplete event handler.

After this is done, Add-in express should generate the code automatically.

Hi Sergey,

really thanks, it's done successfully. One of my problem settled, just another one problem that i am trying to solve it. In the same project, i am trying to detect whether the button "OK" on my web page exist or not.

Example : In test.html, there is a code to create button "OK" like
<input id="btuOK" name="btuOK" type="button" value="OK">

Is it correct if i use declaration like

mshtml::HTMLButtonElement^ btuOK;

OR

mshtml::IHTMLElement^ btuOK;

as a button variable?

Then, i use the following code as my method btuOK_onclick.

private : System::Void btuOK_onclick(){
//If button OK clicked
MessageBox::Show("OK");
}

Is it correct?

TQ.
