M&Ms

First i want to know how i can make a dinamic loading bar like pieces of a clock anything diferent, the game maker owns only retangular bars. And i have a doubt, why games made in game maker dont need other load during the game??? and if can be possible plz send me a example  

i have a doubt, how i can use letters and simbols like this "ç","é","â","ó","ã","¬¬","ª","³" in the draw_text function???

i use game maker 6.1 and no type of bug had ocurred, but when i have downloaded the game maker 7.0 lite version i have tried to play a exemple and the game doesn't load.. he stops at the saving bar and backs to game maker editor.. i dont know what have to do.. i think that the problem not be with my sound card or video card .. no error messages appears too..

any suggestion?

i am making a program that needs to increase or decrease the view size, but the size didn't enlarge more than 640x480, the same size that i put in the "view in room" and "port on screen" i have used this script:

if largura > view_wview[0]
{
view_wview[0] = largura;
view_wport[0] = largura;
}
if altura > view_hview[0]
{
view_hview[0] = altura;
view_hport[0] = altura;
}
}

i've tried this too

if largura > view_wview[0]
{
window_set_size(largura,altura);
view_wview[0] = largura;
view_wport[0] = largura;
}
if altura > view_hview[0]
{
window_set_size(largura,altura);
view_hview[0] = altura;
view_hport[0] = altura;
}
}

but didnt work too  

ps: the view size decrease but don't increase

any one knows if this have a solution?
