    Cleaning all Text fields

    I'm looking for a function, that would clean all EditText fields in a dialog - something like reset in HTML Forms...

    Thanks for help!

    I've never heard of such a function, but search MSDN to be sure. Is there a reason you can't just write a function to do this yourself? Why don't you know what text fields there are on a form?

    There isn't an API function to do this, but the code to implement it is fairly straight forward.

    Code:
    BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam)
    {
    	char empty = 0;
    	char className[32];
    	GetClassName(hwnd,className,sizeof(className));
    	if(!strcmp(className,"Edit"))
    		SendMessage(hwnd,WM_SETTEXT,0,(LPARAM)&empty);
    	return TRUE;
    }
    
    BOOL ClearDlgEdits(HWND hwndDlg)
    {
    	return EnumChildWindows(hwndDlg,EnumChildProc,0);
    }

    thanks for code, but i found one different solution:

    SetDlgItemText(hwnd, IDC_TEXT1, "");

    i have to write this for each Edit field, but I have only 4 fields in Dialog.

    Thanks for help anyway!
