これについて助けが必要です、

3つの画像ボックスがあり、赤は幅を左に拡大し、緑は高さを上に拡大し、青は右に幅を拡大する必要があります

また、上部の境界線/テキストボックスに到達すると、エラーが発生するか、実行が停止します。

将来、画像ボックスを追加する必要があります。そのうちの2つが衝突すると、エラーが発生するか、実行が停止します。私はそれらを上に上げるようにコーディングすることができましたが、他の機能を動作させることができませんでした。誰かがこれを手伝ってください。

また

それを試してみてください。3つのPictureBoxですべてがうまくいく

ヘルプという名前の新しいWidowsアプリケーションを作成し、Form1.csコードをFollowingに置き換えます

それを実行します。TextBoxesからの値も含まれます
