I'm having a problem with mixing managed and unmanaged code. I have created two projects under a single solution in Visual Studio 2008 under Vista x64 SP1. One of them does not have CLR support and is a static library. My second project is compiled as an executable with CLR enabled. It depends on the first static library, and passes WinForms events to it. When I start the application without debugging, I get an exception, I put the info that I get from the exception here: <a href="http://pastebin.com/f46ad1211" rel="nofollow noreferrer">http://pastebin.com/f46ad1211</a>. Here is the code of the unmanaged lib that is run: <pre><code>void manager::init() // <-- Called from the .exe project { this->log.open("C:\\development\\log.txt"); this->storage = storage_manager(&(this->log), &(this->settings)); this->storage.load_settings(); } </code></pre> & <pre><code>void storage_manager::load_settings() { this->error_check(sqlite3_open("settings.db", &(this->db_settings_p))); sqlite3_stmt* read_settings; this->error_check(sqlite3_prepare_v2(this->db_settings_p, "SELECT name, value FROM settings", 1024, &read_settings, NULL)); int step_code; std::string name; std::string value; while(true) { step_code = sqlite3_step(read_settings); if(step_code == SQLITE_DONE) { break; } else if(step_code == SQLITE_ROW) { name = std::string(reinterpret_cast<const char*>(sqlite3_column_text(read_settings, 0))); value = std::string(reinterpret_cast<const char*>(sqlite3_column_text(read_settings, 1))); (*(this->settings))[name] = value; } else { this->error(); } } sqlite3_reset(read_settings); sqlite3_finalize(read_settings); } </code></pre> & <pre><code>void storage_manager::error_check(int rc) { if(rc) { this->error(); } } void storage_manager::error() //Sure of error { std::string error_msg; error_msg = "Storage Manager: SQLite Error ("; error_msg += sqlite3_errcode(this->db_p); error_msg += ") - "; error_msg += sqlite3_errmsg(this->db_p); this->log->write(error_msg.c_str(), error_msg.length()); this->log->flush(); } </code></pre> I can't see why I'm getting a managed (System.BlahBlahBlah) exception in an unmanaged library. Is there any way to get the two to be totally separate?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
