Hi,

we are going through the PB2025R2 and we came across that the WebBrowser control does now support GetSource().

The idea (we do it via OLE at the moment but we are like to go tonew HTML engine) is that we want to load a Confirmation Template HTML in a string (using NavigateToString()), allow users to do some changes on the WebBrowserControl (e.g change the person's address), get the modified HTML code (GetSource()) and email it.

I cannot get it to enter a design mode. Is it only for display-only operations?

Thank you

 

UPDATE: I found a post in here that gave me a solution:

wb_1.EvaluateJavascriptSync("document.designMode = 'on'", REF lsResult, REF lsError)

My new problem is that although I do make change on the browser, the GetSource() returns the initial HTML

 

UPDATE2: Just to sum up: 

The way I ended up doing it:

Fed the control with the HTML code

wb_1.NavigateToString(ls_full_body)

In the NavigationCompleted event of the control I added this code:

string lsResult, lsError
integer llIF issuccess THEN
    ll = this.EvaluateJavascriptSync("document.designMode = 'on';", REF lsResult, REF lsError)

    If ll <> 1 Then
        MessageBox("Error", "JS Failed: " + lsError)
    End If
End If

And in my send function (since the EvaluateJavaScriptSync returns JSON) I added:

string ls_error, ls_bodyjson
wb_1.EvaluateJavascriptSync("document.documentElement.outerHTML", REF ls_bodyjson, REF ls_error)

JsonParser lnv_JsonParser
String ls_Json
Long ll_RootObject

lnv_JsonParser = Create JsonParser
lnv_JsonParser.LoadString(ls_bodyjson)
ll_RootObject = lnv_JsonParser.GetRootItem()

ls_body = lnv_JsonParser.GetItemString(ll_RootObject, "value")

Destroy lnv_JsonParser
