Как писать текст на форме с помощью API

[Morfius]

Если я хочу написать что-то на форме с помощью Api, как мне во первых написать, во вторых регулировать шрифт размер.
И еще, могу я также с помощью Api создовать кнопки, мне кажется я где-то видел пример, но найти не смог... Может есть добрые люди???

p.s. в ApiGuide смотри функции DrawText и DrawTextEx

[Firestorm]

писать мона и так form1.print "asdfasdf"
там и шрифт в проперти смени и всё такое...
с помошью паи смотри в api-guide - в разделе text (можно и поиском)...
DrawTextEx, например...
пример находится на vbnet.ru где-то в примерах...

мля... опять тормазнул.... на 1 минуту
