度々すみません。
Graphicsのインスタンスを取得したんですが、
g->DrawLineでブレイクを掛けても止まりません。
何が原因なのでしょうか?
以下、ソースです。

button1 と ButtonGraph とは何が違うんですか?
どっちも"グラフ表示"ですが、なぜ二つあるんですか?
失礼しました。
グラフ表示がふたつありましたね。
一応、線を引くことができたのですが、Form1上に線を引いてしまいます。
Form2上に線はどのようにして引けばよいのでしょうか?

なぜそうなるかがわかっていれば対処法は明らかですよね。
PictureBoxをForm1,Form2のどちらに貼っていますか?
# いきあたりばったりに書きなぐってデバッグを人任せにしてない?
てかそんなの現象から明らかやん。
pictureBox1->Paint += gcnew System::Windows::Forms::PaintEventHandler
( this, &Form1::pictureBox1_Paint );
↑では、Form1にしていますが、ここはForm2にはできないですよね?
すみません。初心者ですので、
PictureBoxをForm2に貼るというのは、どの命令のことをいっているのでしょうか?
>↑では、Form1にしていますが、ここはForm2にはできないですよね?
ごめん、何言いたいのかわからんです。
> PictureBoxをForm2に貼るというのは、どの命令のことをいっているのでしょうか?
↓こんなのがForm1のメソッド中にありますよ? 自分で書いたんちゃうの?
this->Controls->Add( pictureBox1 );
ありがとうございます。
Form2->Controls->Add( pictureBox1 );
で解決できました。m(__)m
