I want to create a splash screen before my application starts, but i have some troubles with it. I have a image which contains some drawings and it is transparent ( has no background ).
Something like "Blade and Soul" splash screen. I can't post a link here with it, sorry.
I tried to create a panel, give it a color and in my form i set that color to be shown as transparent, but i can still see the borders even though i have set it to be border less.

And another problem that i have encountered is about 3 forms. I have the first form ( main form ), a second form and a third form. I want them to be shown as follow: Main form ( stays 5 seconds on desktop, gets away- i want to hide it - then comes the 2nd form ) Second form ( stays on desktop till i press a button which shows the 3rd form and makes the second one dissapears )
I did this by writing the following code:

Form2->Show();

this->Hide();

Of course, i added a timer and this code is executed after the timer finishes counting so it's 5 seconds.
It works flawless, but from Form2 to Form3 it doesn't work correctly.

Form3->Show();

this->Hide();

I created a button and i wrote this code in it. Form3 appears while Form2 dissapears but then Form2 appears back and i don't understand why...

I'm sorry for my bad english. :)
