I want to write an application interacting with Picasa Web Albums of Google by MFC. I've read this document : http://code.google.com/apis/gdata/basics.html[^] but I still have no idea how to write it in MFC. Some one plz help me :rose:

:D R u present me a software to convert. I would like to use MFC to do that :(.

I'm writing a program to record window activities but I just can save in AVI format. I would like to convert it to WMV format. Some one plz help me :rose:

This is my code :

HWND windowHandle = ::FindWindow(0, _T("Test"));
INPUT *key;
::SetForegroundWindow(windowHandle);
key = new INPUT;
key->type = INPUT_KEYBOARD;
key->ki.wVk = VK_CONTROL;
key->ki.dwFlags = 0;
key->ki.time = 0;
key->ki.wScan = 0;
key->ki.dwExtraInfo = 0;
SendInput(1,key,sizeof(INPUT));
key->ki.dwExtraInfo = KEYEVENTF_KEYUP;
SendInput(1,key,sizeof(INPUT));

::SendMessage(windowHandle,WM_KEYUP,0,0); //==> No effect ?

I've read many pages from the pages you gave me but I still can't find the answer :( They recommend to use SendMessage but it doesn't work with SendMessage...

Plz help me one more time. I would like to know how to send WM_KEYUP by SendInput. When I send a key, it seems to be pressed forever ...

Thank you very much :D

Could you show me an example of using SendInput to send a key to an active window plz ? I find it difficult to find a specific example :(

What do you mean ? Do I have to send three messages at one time ?

I want to send a key to a window. I used Global Hook and my code is like this : //In hook proc : if(nCode <0) CallNextHookEx(MyHook,nCode,wParam,lParam); hWndApp = CWnd::FindWindow(0,_T("Test")); if (hWndApp == NULL) MessageBox(NULL,L" Can't find the window", L"",0); hWndApp->SendMessage(WM_CHAR, 8, 0); //Backspace It can find the window but it can't send the message. Some one plz help me :rose:

Thanks so much Nibu babu thomas, I got it :D

I write a program to capture window controls. I used global mouse hook to catch mouse message. I want that when I move my mouse to a control, there's a rectangle around that control. I got the handle of the control, drew the rectangle but my problem is when I move to another control, the previous rectangle hasn't disappeared yet. I tried RedrawWindow() like this but there was no effect :

CDC *hScrDC;
hScrDC = CDC::FromHandle ( ::GetDCEx(NULL, NULL, 0));
//Tmp is the CDC * of the control
Tmp->RedrawWindow(NULL, NULL, RDW_ERASE | RDW_INVALIDATE | RDW_FRAME | RDW_ALLCHILDREN);
RECT rect;
Tmp->GetWindowRect(&rect);
int nX = rect.left;
int nY = rect.top;
int nX2 = rect.right;
int nY2 = rect.bottom;
hScrDC->Rectangle(nX, nY, nX2, nY2);

Some one plz help me :rose:

I created a dll file like this :

HHOOK MyHook;
HINSTANCE MyInstance;
LRESULT CALLBACK MyMouseHookProc(int nCode, WPARAM wParam, LPARAM lParam);
extern "C" __declspec(dllexport) void Hook();
extern "C" __declspec(dllexport) void Unhook();

//I initialized MyInstance
BOOL CMouseHook1App::InitInstance()
{
CWinApp::InitInstance();
MyHook = NULL;
MyInstance = this->m_hInstance;
return TRUE;
}

void Hook()
{
if(MyHook == NULL && MyInstance != NULL )
{
MyHook = SetWindowsHookEx(WH_MOUSE,MyMouseHookProc,MyInstance, 0);
if(MyHook!= NULL)
MessageBox(NULL,_T(" HOOKED "), _T(""),0);
}
else
MessageBox(NULL,L" Not Hooked", L"",0);

}

LRESULT CALLBACK MyMouseHookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if(nCode <0)
{
CallNextHookEx(MyHook,nCode,wParam,lParam);
return 0;
}

if(wParam == WM_LBUTTONDOWN || wParam == WM_NCLBUTTONDOWN)
{
MessageBox(NULL,_T("OK"),_T("Test"),MB_OK);
PostMessage(hWndApp,WM_LBUTTONDOWN,0,0);
}

return CallNextHookEx(MyHook,nCode,wParam,lParam);

}

But in my app, when I use the function Hook(), it doesn't work at all. Did I do anything wrong? Someone plz help me

Thanks so much :D

I'm using ADO to connect to database in C++. I would like to understand about the technique "Connection pooling" but I can't find any document about it in C++. Some one plz help me ...

Thanks so much. It's really helpful ...

Do you mean setting the visible property to false ? I did so but there's no effect :(

I have an app with an icon on system tray. I want to hide the window (just let the icon appear). I tried to use dlg->ShowWindow(SW_HIDE)instead of DoModal() but when the icon appears, it's useless (when we move the mouse to it, it disappears). Someone plz give me a solution, thanks :rose:

I don't know :-O I will wander some IT forum to ask if anyone has the same problem. Thanks for all of your answers :)
