send CTRL-C to dchtmlviewer

[rdonnay]

We would need to know what the Input() class is.
Where does it come from?

Hi Roger,

I suppose it comes from ot4xb.

The following code comes from the htmleditor. It can be used to send a keystroke to the active application.

Problem is that I don't succeed to set the dc_htmlviewer as active or as focused component/dialog.
In the htmleditor code there is a COPY method and a SETFOCUS() method. It looks as the setfocus doesn't work when a PDF file is shown in the htmlviewer. The methods hasfocus() and focus() don't exist in the adobe activex for the pdf viewer.

I tried with events as ldDblClick, Killinputfocus, setInputFocus but I don't succeed.

Code: Select all

PROCEDURE SendCtrlKey( xKey )

   oInput:ki:wVk:= VK_CONTROL

GwstArrayNext(oInput)
   oInput:type  := INPUT_KEYBOARD
   oInput:ki:wVk:= xKey

GwstArrayNext(oInput)
   oInput:type      := INPUT_KEYBOARD
   oInput:ki:wVk    := VK_CONTROL
   oInput:ki:dwFlags:= KEYEVENTF_KEYUP

GwstArrayNext(oInput)
   oInput:type      := INPUT_KEYBOARD
   oInput:ki:wVk    := xKey
   oInput:ki:dwFlags:= KEYEVENTF_KEYUP

@user32:SendInput( nEvents, pBuffer, nSize )

oInput:_unlink_()
_xfree( pBuffer)
RETURN

Do you have a sample program that I can work with?

Hi Roger,

The above comes from c:\exp20\Samples\HtmlEdit_2\

It is working when there is HTML in the viewer. Then there is oHtmlviewer:document. When there is a PDF showing, it isn't clear to me how to set focus to i

Roger,

Meanwhile I added some code to your fileviewer sample. This way it will be easier to start with it.

I added a button to send the CTRL-C to the active-X window.

This should be possible:
- Double click a word in the PDF.
- Click on the 'send CTRL-C' button, so the selected word is copied to the clipboard.

If you use CTRL-C on the keyboard, the copy is done.

There is some testing code in it, so you can see what I tried.

It is ready to compile and run.

I copied some methods from the html viewer sample. I also copied some functions that are used in that sample. This way the input object is created.

The necessary include files are also added.

I suppose you have the ot4xb.dll? If not, I added it to the zip-file.

[rdonnay]

I tried a bunch of changes to your test app but I cannot determine a way to do this.

My guess is that the PDFViewer ActiveX Control does not receive events from the XbpHtmlViewer Active X control.

Roger,

I tried it also in different ways, but I also didn't succeed.

Thanks for taking your time to test this.

hi,

I suppose it comes from ot4xb.

SendInput* is a API function which is used now while keybd_event** API function is deprecated

In the htmleditor code there is a COPY method and a SETFOCUS() method. It looks as the setfocus doesn't work when a PDF file is shown in the htmlviewer. The methods hasfocus() and focus() don't exist in the adobe activex for the pdf viewer.

you have to use Windows API function "SetFocus" not Xbase++ function
