Thread: very bad delay in picking up WM_MOUSEMOVE

I set my dialog proc to pick up WM_MOUSEMOVE

in my dialog proc :

Code:

BOOL CALLBACK MenuProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
    switch(Message)
    {
        case WM_INITDIALOG:
			{


			}
			break;
        return TRUE;


			
		case WM_MOUSEMOVE:
			{
				MessageBox(NULL, "mouse is IN!", 
					"GOOD",MB_ICONEXCLAMATION | MB_OK);		
			}
			break;
.....

mouse is IN!" messagebox come only after about 5 seconds of my mouse constantly moving in the window area. This is bad because i need immediately response. I have no idea how the 5 seconds delay come about. I ran spy++ to check on the messages sent to the dialog and they were all fine and constant flowing

any idea what's going on??

using
- win98se
- vc++6.0
- API style of coding

You're causing your dialog proc to recurse infinately...

Code:

case WM_MOUSEMOVE:
{
    static bool showing = false;

    if (!showing)
    {
        showing = true;
        MessageBox(NULL, "mouse is IN!", "GOOD", 
                   MB_ICONEXCLAMATION | MB_OK);		
        showing = false;
    }
}
break;

gg

Thnx for reply
why am i causing it to recurse repeatly??
is it because of
MessageBox(NULL, "mouse is IN!", "GOOD",
MB_ICONEXCLAMATION | MB_OK); ??

i tried the code you provided but it still doesnt solve the problem of the delay...
i used this

Code:

		case WM_MOUSEMOVE:
			{
				static bool showing = false;
				if (!showing) // if it's false
				{
					showing = true;
					OutputDebugString("mouse is IN!\n");	
					showing = false;
				}
			}
			break;

what happens is that OutputDebugString("mouse is IN!"); causes the string "mouse is in" to be displayed onto the debugging section of vc++6.0 everytime it picks up the WM_MOUSEMOVE message

still... the unwanted delay is there. What would be expected would be a very quick repeated strings occurring non-stop everytime i move my mouse on the client area

I ran Spy++ to spy on the messages sent to the window and saw a non-stop repeated string of mousemove messages flowing.

ok guys, this might be rather interesting....

Code:

BOOL CALLBACK MenuProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
	char tempx[10];
	tempx[0] = '\0';
	_itoa( Message , tempx, 10);
	strcat(tempx,"\n");

	OutputDebugString(tempx);

	



    switch(Message)
    {
							


        case WM_INITDIALOG:
			{


			}
			return TRUE;
	//	break;

		case 32:
			{
					OutputDebugString("mouse really moved");	
			}
			break;
					
		case WM_MOUSEMOVE:
			{
					OutputDebugString(" WM_MOUSEMOVE message picked up");	
			}
			break;

i changed wm_mousemove to int 32 and it worked!! no more delays. Strange huh?? anybody knows why?

Why do you insist on posting Windows Programming in the non-Window Programming forum?
