を使用して実行可能ファイルを実行するプログラムがあります。私が呼び出す実行ファイルは、ProgramData
のフォルダを更新する第三者プログラムです。 ProgramData
のフォルダが更新されると、プログラムの次の行が更新され、最新の変更が読み込まれます。ProgramDataの最新の変更を読み取ることができません
私は、実行可能ファイルが実行された後でも最新の変更を読み取ることができないことに気付きました。しかし、私が最初からプログラムを再実行すると、変更が正しく読み取られることがわかります。私はこれが実行中に変更を見ることができないAppDomain
と関係があると仮定しています。
私はここで働くことができますか?方法HSMTransactionHandler
内部以下のコードで
HSM_ENCRYPTION_KEY_NOT_FOUND
メッセージと例外が発生した場合、私はメソッドUpdateFromRFS
を呼び出すことによって、EXEを実行し、再帰的HSMTransactionHandler
を呼び出します。 exeの実行は必要なリソースを取得しますが、コードはそれを読み取っていません。現在のプログラムの実行中に別のプログラムを実行すると、2番目のプログラムは問題なくリソースを読み取ります。どのようにして、プロセスやアプリケーションドメインが起動した後にProgramData
フォルダに起こった変更を見ることができるのでしょうか?
私はPKCS11Interop
ライブラリを使用していて、ネイティブdllの周りに構築された.net
ラッパーを使用していることを知っています。ネイティブdllを使用するとこの問題が発生する可能性があるかどうかもわかりません。
ご協力いただければ幸いです。
