私はメッセージError reading characters of stringUnable to read memoryを受け取り続けます。私はCString.Format（）関数が呼び出されたときにすべてが順番になっているように見えるので、それを修正する方法がわかりません。ここでCString Format（）がメモリを読み取れません。
は、エラーが発生しstrnlen.cppのスポットです：これはstrnlen呼び出している関数である 
： 
そして、ここでは、休憩の時に地元の人々です。 cpp（最後の行はブレークが発生する場所です）：
char comp[50];
gethostname(comp,50);
CString textmsg;
textmsg.Format("%s %s: %s",TEXT,comp, m_edit_message);
m_edit_messageはCString変数です。最後に、ここで

は、あなたが何を考えてやっていない
、sizeof(myTestArray)/sizeof(myTestArray[0]は8に等しい：
「テキスト」とは何ですか？どのように初期化されますか？ 'm_edit_message'とは何ですか？どのように初期化されますか？ 'gethostname'への呼び出しは成功しましたか？私の推測*は、 'TEXT'か' m_edit_message'のどちらかが普通のC文字列ポインタ（または配列）ではなく、Cスタイルの文字列への明示的なキャストなしには本当に使用できない 'CString'オブジェクトのようなものですポインタ。 –
また、それは何ですか？ [最小、完全、および検証可能な例]（http：//stackoverflow.com/help/mcve）で再現可能なエラーを作成してください。 –
