Pasting to any window

I managed to paste text that is currently in the clipboard using this:

CString csText = "Test";
HGLOBAL hglbCopy;

if(OpenClipboard())
{
EmptyClipboard();
TCHAR *wcBuffer = 0;
hglbCopy = GlobalAlloc( GMEM_MOVEABLE, (csText.GetLength() + 1) * sizeof (TCHAR));

wcBuffer = (TCHAR*)GlobalLock(hglbCopy);
_tcscpy(wcBuffer, csText);

GlobalUnlock(hglbCopy);
SetClipboardData(CF_TEXT, hglbCopy);
CloseClipboard();
}
}

// And then:

POINT pt;
GetCursorPos(&pt);
CWnd* editControl;
editControl = WindowFromPoint(pt);
editControl->GetFocus();
editControl->SendMessage(WM_PASTE, 0, 0);


It does work for notepad but it does not work for other apps ( for example - Word and a textbox in a browser window)


I've also tried to programatically click Ctrl+V and cause a paste like this:
editControl->SendMessage(WM_CHAR, 22, 0x56);

But it seems to have the same problem - only works in some places (notepad...)


Any idea how can I make this work for any input control ?
(just like Ctrl+V works for every control)

Try to use SendInput API rather than sending WM_CHAR message.

Still the same results - works on notepad but not in Word or in browser's textboxes

This is what I've used:
(should I try to change anything ?)


INPUT *key;
key = new INPUT;
key->type = INPUT_KEYBOARD;
key->ki.wVk = VK_CONTROL; // virt key code
key->ki.dwFlags = 0; // flags—see doc
key->ki.time = 0; // time stamp, 0 = dflt
key->ki.wScan = 0; // hw scan code
key->ki.dwExtraInfo = 0; // app-defined
SendInput(1,key,sizeof(INPUT));
//key->ki.dwExtraInfo = KEYEVENTF_KEYUP;
//SendInput(1,key,sizeof(INPUT));

key = new INPUT;
key->type = INPUT_KEYBOARD;
key->ki.wVk = 'V'; // virt key code
key->ki.dwFlags = 0; // flags—see doc
key->ki.time = 0; // time stamp, 0 = dflt
key->ki.wScan = 0; // hw scan code
key->ki.dwExtraInfo = 0; // app-defined
SendInput(1,key,sizeof(INPUT));
//key->ki.dwExtraInfo = KEYEVENTF_KEYUP;
//SendInput(1,key,sizeof(INPUT));

Also, FYI: I'm running Vista 64bit

:confused:



I do something like that in my Apps: However I go to ClassWizard and created a 'Member Control Variabale of the Edit box of CEdit type':

Code:

---


        CString source;
        //put your text in source

        source = "Line 1  :\r\n"     
                        "Line2    :\r\n"     
                "...etc,  :\r\n"     
                ".....";                               
                       
                       
        if(OpenClipboard())
        {
                HGLOBAL clipbuffer;
                char * buffer;
                EmptyClipboard();
                clipbuffer = GlobalAlloc(GMEM_DDESHARE, source.GetLength()+1);
                buffer = (char*)GlobalLock(clipbuffer);
                strcpy(buffer, LPCSTR(source));
                GlobalUnlock(clipbuffer);
                SetClipboardData(CF_TEXT,clipbuffer);
                CloseClipboard();
        }
       
        this->m_CntrlNotes.Paste();      //m_nCntrNotes is a CEdit Control Variable assigned in ClassWizard
        this->UpdateData();
        AfxMessageBox(m_Notes); //m_Notes is a varaiable assigned to the edit box in ClassWizard

---

This will copy a string to the clipboard and into an Edit control assigned to an edit box via Classwizard.

Still the same results - works on notepad but not in Word or in browser's textboxes

I've added this:

((CEdit*)editControl)->Paste();

instead of editControl->SendMessage(WM_PASTE, 0, 0L);


I wonder if there is some kind of Vista built-in security feature that is preventing me from doing this...

Are you trying to paste directly into MS WORD?

Also right into Html code? or into the address bar of the Browser?

Yes I was trying to paste into Word,

When I hit a hot key my function do copy the data into clipboard, but on Word it does not do the paste,
however, if I hit Ctrl+V it does copy my value from clipboard,

Also, it does work for the address line of Internet Explorer,
but not for TextBox inside web sites - for example: the search box at the google web page,

Thanks again.

Well the Edit box in a browser in NOT a CEdit control, the browser has over written the Ctrl-Paste function. ... I doubt you have access to that via, MFC.


MSWORD is another story. The client area probobly not a CEdit box.


I was doing some stuff a few month's ago where I had to get the address line of the brower, or a specif instance of the Browser. ... i.e, several sites were open.

I had to use FindWindow, and get into the use of that function. It gets pretty messy.

Regarding getting data into MSWORD you might have more success with that. What I posted only works with CEdit Boxes.

Regarding geting data in the edit boxes of the browers client area. I'm not sure if we have access to that via MFC. ..... Like I said I don't do much Internet stuff, so I could be wrong, I just know that those boxes in the Client area are not CEdit boxes.

One way of getting data into the Google Box would be to download the webpage into a file edit it and call that html file via the browser, basically scrub the file.

Well here you go, I think this get access to the Client area in the Browser.

Simply use COM

Your SendInput sequence is not entirely correct. Use this one it should work ( works for any of my applications )

Code:

---

void SendPaste()
{
        INPUT Input[4];
        memset(Input, 0, sizeof(Input));
        Input[0].type = INPUT_KEYBOARD;
        Input[0].ki.wVk = VK_CONTROL;
        Input[0].ki.dwFlags = KEYEVENTF_EXTENDEDKEY;
        Input[1].type = INPUT_KEYBOARD;
        Input[1].ki.wVk = 'V';
        Input[2].type = INPUT_KEYBOARD;
        Input[2].ki.wVk = 'V';
        Input[2].ki.dwFlags = KEYEVENTF_KEYUP;
        Input[3].type = INPUT_KEYBOARD;
        Input[3].ki.wVk = VK_CONTROL;
        Input[3].ki.dwFlags = KEYEVENTF_KEYUP | KEYEVENTF_EXTENDEDKEY;
        SendInput(4, Input, sizeof(Input[0]));
}

I like your SendInput sequence better, but I'm getting the same results,

if you say its working for you then I really start to think that it is something related to my Vista 64bit

I will try it in some other Windows emulators with Virtual PC and see,

Thanks.

Can you show us the exact code you are using at the moment (not only the SendInput sequence ) but all the parts . maybe if you could attach a sample project we could test on our pcs it would help debug the issue.

I gave him some links that expllain why he can't post information to Word (think about it, do you really think that Word is just one bigcCEdit Class, .. maybe a Richedit control, but most likely something derivied from CWND!, I havn't read the article but I'm sure he addresses it) .

Regarding posting information into forms: He has to get the content of the web page and parse the contents via CHtmlView->GetHtmlDocuement(); It's not a trivial task, it requires somes knowledge of COM and IHtmlDocument2 with one of the last SDK's if you are using V6 (which I' am and are having problems getting the SDK created in 2003 for V6, to work) or compiler newere than V6, since accessing a HTML Form requires having access to IHTMLelementPTR.


In a nutshell those are not CEdit Classes he is trying to communicate with, sendig a message via CEdit is not going to get you anywhere with those two apps he is trying to communicate with: .... it like the old saying, "Don't send a BOY to do a mans job". Your going to have to roll up your sleeves to get information to WORD and a HTML Form!!!

This might be the comand to solve you Web Editing problems

CHtmlEditCtrlBase::TextBox

Yes, thats true - I rather make it work with CWnd or by broadcasting some message than try to talk to each control separately,

I dont intend to try figure out how to post it through IE COM objects, who knows how many different object I have to deal with other than this one (Firefox, Word, other programs with strange COM objects...)

What I still dont understand is why SendInput() is not simulating Ctrl+V correctly and causes whatever COM object or edit control to do the actual paste to where the current cursor foucs is at.

May be interesting to read this "Nick on Silverlight and WPF" http://blogs.msdn.com/nickkramer/arc...15/576758.aspx

Greetings.

Very interesting article,

So how can I set my app to be at the highest privilege level ?

Anyone has a clue ?

Unfortunately I can't help on that question, but I suppose that the application per se can't do that, because it go against any security principle. I suppose that the application need to be started by a user of adequate rights. Although of course this is only an aloud thought.

I think this is the case here - I will try my app on an older OS and post the results here...

Maybe this should be used (with different SE_ flags... ?):



HANDLE hToken;
TOKEN_PRIVILEGES tkp;

if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) {}
LookupPrivilegeValue(NULL, SE_SECURITY_NAME, &tkp.Privileges[0].Luid);

tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
if (GetLastError() != ERROR_SUCCESS) {}
