Tenta comentar o código, pode ser que assim alguém te ajude.... mas nao foi boa ideia teres usado o meu post para resolver o teu problema, uma vez que eu ja meti no titulo "RESOLVIDO" poucas serão as pessoas que irão abrir o post.

E já agora a Techzone não é o melhor lugar para tirares as tuas dúvidas, pois bem que te podes matar que poucas serão as respostas....

Ai terás mais ajuda !

Espero ter ajudado de alguma forma

void_ · 20 de Fevereiro de 2008

Boas! Qual é o teu problema na subtracçao?

O teu código o esta optimizado, no entanto teria obrigação de funcionar com:

string vl2 = tbx01.Text;
int vl22 = int.Parse(vl2);

tbx01.Clear();
int vl1 = int.Parse(label1.Text);
int res = vl1 - vl22;
tbx01.Text = res.ToString();

Diz qual é a tua duvida que fica mais facil ajudar :S
