Есть такой текст, если в диалоге выбрать сервер из допустимых в комобоксе, а потом попытаться выбрать базу, то на раскрытии комбобокса со списокм баз выдается exception "Unhandled Exception".
А если делать то же, но при выборе сервера ввести его имя вручную, то и базу можно выбрать и все работает ок.

С чем это может быть связано??

private void FormMainLoad(object sender, System.EventArgs e)
{
try
{
oleDbConnection1.Open();
}
catch(System.Data.OleDb.OleDbException myException)
{
for (int i=0; i < myException.Errors.Count; i++)
{
if(myException.Errors .NativeError!=0)
MessageBox.Show("Index #" + i + "\n" +
"Message: " + myException.Errors.Message + "\n" +
"Native: " + myException.Errors.NativeError.ToString() + "\n" +
"Source: " + myException.Errors.Source + "\n" +
"SQL: " + myException.Errors.SQLState + "\n");
}
Application.Exit();
}
}

Те, которые в стандартном OLeDb-окне выбора сервера, базы, юзера, если указать OleDBConnection.ConnectionString="...;PROMPT=1;..."

Кто-нибудь посдкажет, гуру?

Поставил такой exception, результат:
"No error information available: E_UNEXPECTED(0x8000FFFF)"
Причем такое же на нескольких машинах....:-((

Еще details для этой ошибки:

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.
