[RESOLVED] Trying to close a bubble window that pops up from a tray icon

I am configuring the windows supplicant for 802.1x. While doing so, it pops up a bubble notification from a tray icon that says something like "Click to provide additional information..." I wish to suppress this so I do not get this bubble notification. I figured I could enumerate through all the windows and send that window a WM_CLOSE.

Anyway if I enumerate through child windows of the desktop I never see this window (code follows). However if I use a dev studio 2008 tool, spy and I use the find window and drag the cursor thing over the window, it finds it.

So what am I doing wrong and/or is there a better way to go about doing this.

Code:

---

#define SEARCH_TEXT_XP2000        "Click here to enter your user name and password for the network"
#define SEARCH_TEXT_VISTA        "Click to provide additional information and connect"
//#define SEARCH_TEXT_VISTA        "additional information"
       
// Size of the smaller of the above strings
#define SEARCH_TEXT_LEN sizeof(SEARCH_TEXT_VISTA)

// Window Clicker section.  There are some windows
BOOL CALLBACK EnumFunc(HWND hwnd, LPARAM lParam)
{
        int Len;
        char Buffer[1025];
        bool *DidClick = (bool *)lParam;
        Buffer[0] = 0;
       

        Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

        if (Len >= SEARCH_TEXT_LEN)
        {
                CString MatchBuff;
                MatchBuff = Buffer;
                printf("%s\n", MatchBuff.GetString() );

                if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                {
                        SendMessage(hwnd, WM_CLOSE , NULL, NULL);
                //        SendMessage(hwnd, WM_LBUTTONUP , NULL, NULL);
                        *DidClick = true;
                        return FALSE;       
                }
        }

        return TRUE;
}



void WaitForClick(void)
{
        bool DidClick = false;

        while ( false == DidClick)
        {
                printf(" ------------ \n");
                EnumChildWindows(GetDesktopWindow(), EnumFunc, (LPARAM)&DidClick);
                Sleep(500);
                printf(" ------- \n");
        } 
}

---

I also printed out the windows to the console and verified that I do not see that window anywhere.

It only means that this window is NOT a child of the desktop window.

Well, then look at the parent of this window in the Spy++, then at the parent of the parent and so on until you find out the desktop window...

It's parent window is just a handle with no caption or anything. That window has no parent. I thought all windows were children of the desktop window. So how do I find that window?

But this window always has some window class! It is what need!

It is tooltips_class32. How does this help me? I am apparently not as smart or knowledgeable as you think I am.

I have tried this additional code, which I would think should find every window, but it doesn't.

Code:

---

#define SEARCH_TEXT_XP2000        "Click here to enter your user name and password for the network"
#define SEARCH_TEXT_VISTA        "Click to provide additional information and connect"
//#define SEARCH_TEXT_VISTA        "additional information"
       
// Size of the smaller of the above strings
#define SEARCH_TEXT_LEN sizeof(SEARCH_TEXT_VISTA)

// Window Clicker section.  There are some windows
BOOL CALLBACK EnumChildFunc(HWND hwnd, LPARAM lParam)
{
        int Len;
        char Buffer[1025];
        bool *DidClick = (bool *)lParam;
        Buffer[0] = 0;
       

        Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

        if (Len >= SEARCH_TEXT_LEN)
        {
                CString MatchBuff;
                MatchBuff = Buffer;
                printf("%s\n", MatchBuff.GetString() );

                if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                {
                        SendMessage(hwnd, WM_CLOSE , NULL, NULL);
                //        SendMessage(hwnd, WM_LBUTTONUP , NULL, NULL);
                        *DidClick = true;
                        return FALSE;       
                }
        }

        return TRUE;
}


BOOL CALLBACK EnumAllFunc(HWND hwnd, LPARAM lParam)
{
        EnumChildWindows(hwnd, EnumChildFunc, (LPARAM)lParam);
        return TRUE;
}


void WaitForClick(void)
{
        bool DidClick = false;

        while ( false == DidClick)
        {
                printf(" ------------ \n");
                EnumWindows( EnumAllFunc, (LPARAM)&DidClick);
                Sleep(500);
                printf(" ------- \n");
        } 
}

Use EnumWindows instead of EnumChildWindows.

You have to use Spy++ to obtain the whole windows hierarchy from your window and up to desktop one; for each window from this hierarchy you will need to know the window classes to use them then in your enumerations...

You don't need to use EnumChildWindows at all if you are looking for a window which isn't a child.
Try this - your original code from the first post with one line altered (highlighted in red):

Code:

---

#define SEARCH_TEXT_XP2000        "Click here to enter your user name and password for the network"
#define SEARCH_TEXT_VISTA        "Click to provide additional information and connect"
//#define SEARCH_TEXT_VISTA        "additional information"
       
// Size of the smaller of the above strings
#define SEARCH_TEXT_LEN sizeof(SEARCH_TEXT_VISTA)

// Window Clicker section.  There are some windows
BOOL CALLBACK EnumFunc(HWND hwnd, LPARAM lParam)
{
        int Len;
        char Buffer[1025];
        bool *DidClick = (bool *)lParam;
        Buffer[0] = 0;
       

        Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

        if (Len >= SEARCH_TEXT_LEN)
        {
                CString MatchBuff;
                MatchBuff = Buffer;
                printf("%s\n", MatchBuff.GetString() );

                if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                {
                        SendMessage(hwnd, WM_CLOSE , NULL, NULL);
                //        SendMessage(hwnd, WM_LBUTTONUP , NULL, NULL);
                        *DidClick = true;
                        return FALSE;       
                }
        }

        return TRUE;
}



void WaitForClick(void)
{
        bool DidClick = false;

        while ( false == DidClick)
        {
                printf(" ------------ \n");
                EnumWindows( EnumFunc, (LPARAM)&DidClick);
                Sleep(500);
                printf(" ------- \n");
        } 
}

---

Peter_B: This works no better...

Code:

---

BOOL CALLBACK EnumAllFunc(HWND hwnd, LPARAM lParam)
{
        int Len;
        char Buffer[1025];
        bool *DidClick = (bool *)lParam;
        Buffer[0] = 0;
       

        Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

        if (Len >= SEARCH_TEXT_LEN)
        {
                CString MatchBuff;
                MatchBuff = Buffer;
                printf("%s\n", MatchBuff.GetString() );

                if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                {
                        SendMessage(hwnd, WM_CLOSE , NULL, NULL);
                //        SendMessage(hwnd, WM_LBUTTONUP , NULL, NULL);
                        *DidClick = true;
                        return FALSE;       
                }
        }
}

void WaitForClick(void)
{
        bool DidClick = false;

        while ( false == DidClick)
        {
                printf(" ------------ \n");
                EnumWindows( EnumAllFunc, (LPARAM)&DidClick);
                Sleep(500);
                printf(" ------- \n");
        } 
}

VictorN: I still do not understand what you mean. Why do I need to know the windows class for my enumerations? None of those API calls use a windows class. Is there an API call that uses the windows class that I do not know of?

Just because, as you wrote:

Then read MSDN about window functions and window class...
About Windows

The problem isn't actually anything to do with not finding the window now. It is to do with your string matching code not working.

Look at these #defines:

Code:

---

#define SEARCH_TEXT_VISTA        "Click"
#define SEARCH_TEXT_LEN sizeof(SEARCH_TEXT_VISTA)

---

(I've shortened the string for clarity)
Now, SEARCH_TEXT_LEN will be 6 as it includes the null terminator.

But the result of this

Code:

---

Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

---

for a window with text "Click" will be that Len = 5, as the return value for WM_GETTEXT is the number of characters copied, not including the terminating null character.

Therefore, even if you find the correct window, this line:

Code:

---

if (Len >= SEARCH_TEXT_LEN)

---

will not work.

Thanks peter_b, that could be a problem and I could have missed that window title however with this change to that function:

Code:

---

CString Output;

// Window Clicker section.  There are some windows
BOOL CALLBACK EnumChildFunc(HWND hwnd, LPARAM lParam)
{
        int Len;
        char Buffer[1025];
        bool *DidClick = (bool *)lParam;
        Buffer[0] = 0;

        if ( true == *DidClick )
        {
                return FALSE;
        }
        else
        {
                Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

                CString MatchBuff;
                MatchBuff = Buffer;
                if ( Len > 2 )
                {
                        printf("%s\n", MatchBuff.GetString() );
                        Output += MatchBuff + "\n";
                }

        //        if (Len >= SEARCH_TEXT_LEN)
                {
                       
                        if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                        {
                                SendMessage(hwnd, WM_CLOSE , NULL, NULL);
                                //        SendMessage(hwnd, WM_LBUTTONUP , NULL, NULL);
                                *DidClick = true;
                                return FALSE;       
                        }
                }


                return TRUE;
        }
}

I am saving all the window titles in the CString output. Now after one full iteration of that loop I should have the window name in the Output string, right? It has like 8000 window names in it when I run it. I pasted that string into a text editor and searched for all instances of the word "click" or "additional". That window name is not found, even though I make sure the pop-up window title is still visible during the whole enumeration. I even cut and past the text I got from the spy program just to be sure.

For whatever reason this window will not show up. Any ideas? Maybe these tool-tip pop-up windows are special and do not show up during a normal enumeration?

Is this using EnumChildWindows or EnumWindows?

Can you still find it with Spy++?
If Yes / have you found out the window hierarchy from this window up to all its parents?

Peter_b: EnumChildWindows, sorry about that. Here is the complete code I used:

Code:

---

#define SEARCH_TEXT_XP2000        "Click here to enter your user name and password for the network"
#define SEARCH_TEXT_VISTA        "Click to provide additional information and connect"
//#define SEARCH_TEXT_VISTA        "additional information"

// Size of the smaller of the above strings
#define SEARCH_TEXT_LEN sizeof(SEARCH_TEXT_VISTA)


CString Output;

// Window Clicker section.  There are some windows
BOOL CALLBACK EnumChildFunc(HWND hwnd, LPARAM lParam)
{
        int Len;
        char Buffer[1025];
        bool *DidClick = (bool *)lParam;
        Buffer[0] = 0;

        if ( true == *DidClick )
        {
                return FALSE;
        }
        else
        {
                Len = (int)SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)Buffer);

                CString MatchBuff;
                MatchBuff = Buffer;
                if ( Len > 2 )
                {
                        printf("%s\n", MatchBuff.GetString() );
                        Output += MatchBuff + "\n";
                }

        //        if (Len >= SEARCH_TEXT_LEN)
                {
                       
                        if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                        {
                                SendMessage(hwnd, WM_CLOSE , NULL, NULL);
                                //        SendMessage(hwnd, WM_LBUTTONUP , NULL, NULL);
                                *DidClick = true;
                                return FALSE;       
                        }
                }


                return TRUE;
        }
}


BOOL CALLBACK EnumAllFunc(HWND hwnd, LPARAM lParam)
{
        EnumChildWindows(hwnd, EnumChildFunc, (LPARAM)lParam);
        return TRUE;
}



void WaitForClick(void)
{
        bool DidClick = false;

        while ( false == DidClick)
        {
                printf(" ------------ \n");
                EnumWindows( EnumAllFunc, (LPARAM)&DidClick);
                Sleep(500);
                printf(" ------- \n");
        } 
}

VictorN: The spy thing has given me some weird, seemingly conflicting info on this window, Ill try and describe it:

You know the normal window list interface that lists all the windows in a tree view? Under this view, it shows this window as a child of the desktop window, however when you select it using the find window where you drag the icon, it says it's parent is the shell tray or the "Shell_TrayWnd" class.

Again under the graphic / tree view this window is not under this shell tray window, but when you go through the dialog and ask it for the parent, the parent is said to be the shell tray window.

Another slight difference in nomenclature is that the Spy program lists this string as the "Window Caption". Is this the same as the windows text I get as used with "WM_GETTEXT" message? If not, what message should I use to get the caption?

Just to make sure you've covered all bases, have you tried it with just EnumWindows? I.e.

Code:

---

CString Output;

BOOL CALLBACK EnumFunc(HWND hwnd, LPARAM lParam)
{
        // Get text and add to 'Output' etc...

        return TRUE;
}

void WaitForClick(void)
{
        bool DidClick = false;

        while ( false == DidClick)
        {
                printf(" ------------ \n");
                EnumWindows( EnumFunc, (LPARAM)&DidClick);
                Sleep(500);
                printf(" ------- \n");
        } 
}

---

Enum windows only does top level windows, not their children. I have tried it, and it does indeed return less results than EnumChildWindows.

There has to be a way to do this. I have no idea why this pop-up window is special, although I am not getting any other popup windows either.

I tried to find the processes, but when I click on the processID in spy, spy crashes.

So, find the Shell_TrayWnd window and enum its childen!

I did, and guess what? NADA. Didn't find it. I think tool-tip windows are special and do not show up.

What did you do?
Have you found the Shell_TrayWnd window?
Have you enumerate its children?

I figured out the general solution, I do not know why this works when enum windows does not, however here it is:

Code:

---

#define SEARCH_TEXT_XP2000        "Click here to enter your user name and password for the network"
#define SEARCH_TEXT_VISTA        "Click to provide additional information and connect"

void WaitForClick(void)
{
        bool Loop = true;

        char Buffer[1025];
        Buffer[0] = 0;

        while ( Loop )
        {
                HWND h1 = NULL, h2 = NULL;

                h1 = FindWindowEx(NULL, h2, "tooltips_class32", NULL);
                while ( h1 != NULL )
                {
                        int Len;

                        Len = (int)SendMessage(h1, WM_GETTEXT, 1024, (LPARAM)Buffer);

                        CString MatchBuff;
                        MatchBuff = Buffer;

                        if ( Len > 2 )
                        {
                                if ( (-1 != MatchBuff.Find(SEARCH_TEXT_XP2000)) || (-1 != MatchBuff.Find(SEARCH_TEXT_VISTA)) )
                                {
                                //        CloseWindow( h1 );
                                //        SendMessage( h1, WM_CLOSE, NULL, NULL );
                                        ShowWindow( h1, SW_HIDE );
                                       

                                        Loop = false;
                                        break;
                                }
                        }

                        h2 = h1;
                        h1 = FindWindowEx(NULL, h2, "tooltips_class32", NULL);
                }
        }
}

---

The only side effect of this is that the CloseWindow seems to cause the tool-tip window to become corrupt. When it pops the window up the next time (by going through the steps to get it to show naturally on its own) the window is all the wrong size and looks like a simple, short text box. The SendMessage() with WM_CLOSE seems to have made the window disappear all together and I may need to reboot to get it to show up again.

Once I get it back, Ill try SW_HIDE and maybe that will be gentler and just make it go away without corrupting it. Doesn't clicking on the close gadget in a window send the WM_CLOSE message?

Anyway this is resolved and thanks for all your help.
