connection

问题 I got another JCo-related question and hopefully finding help. With JCo you can easily build up a connection like it is explained in the example sheets which came with the JCo-library. Unfortunately, the only way building a connection is handled with a created property file. It wouldn´t be that bad, if there wasn´t any sensible data in it. But at least, the password for the SAP user stands in the file, so it is a lack of safety in this way of connection-handling. The manual of JCo says so,

问题 I am still struggling with AS3, but willing to learn as much as possible. I'm trying to write a small sample flash application which will be able to sent variables to the serial ports using socket class. I've done my homework and I know that flash can not sent data over serial ports like COM and USB. To do so you have to use use a program which will receive the outgoing data from Flash and send it to desire port. The best example of such process is described on Arduino website. From there I

问题 is there any way, to restrict hibernate not to create connection of its own(what we define in hibernate.properties or hibernate.cfg.xml), instead i can create and pass the connection to hibernate for further processing. The problem is that i need to set the ApplicationContext on the connection given that the i am using oracle connection. I know how to create a connection and set the applicationContext on to it.. but the problem is that i don't know how to force hibernate to use the connection

问题 here's my existing connection code, which works fine json_key = json.load(open('path/to/json.js')) scope = ['https://spreadsheets.google.com/feeds'] credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope) gc = gspread.authorize(credentials) but after 10 mintutes or so my connection will time out. after reading around a bit i came across the use of this in the connection code, headers = gspread.httpsession.HTTPSession(headers={'Connection':'Keep

问题 When you first open the app I want a screen where you can enter the broker information and click try and save. When clicking try it should just show a Snackbar saying if the information makes for a successful connection. This is the code I call when the try button is pressed: private void tryConnection(View v){ if(verifyInputs()){ Snackbar.make(v, getString(R.string.trying_connection), Snackbar.LENGTH_LONG).show(); String clientId = MqttClient.generateClientId(); MqttAndroidClient client =

问题 I can't figure out why my Java Server with Socket and ServerSocket is that slow while sending objects. Here a small ping program to demonstrate my problem. If I run both client and server on the same machine, everything is fine ofc (<1ms ping time). However, if I move the Server to a Linux machine I get a ping time of >500ms (ping via command line to that machine says 20ms). Thanks in advance Server: public static void main(String[] args) { try { ServerSocket serverSocket = new ServerSocket

问题 Been trying unsuccessfully to make the Hybrid Connection Manager work, it's my first hands-on experience: On Azure portal: I've installed Hybrid Connection Manager on my laptop (using local admin account, Win 7 Enterprise) and also used it as on-premise endpoint for a MS SQL Express instance. psPing (great toolset by Mark Russinovich) shows connectivity on port 1433 and I can connect through SSMS without any issue. I tried this in a workshop today and one of the trainers was able to get

问题 I have a function that attempts to clear every connection string from every connection, it works as follows: Public Sub RemovePasswordByNamePrefix() Dim w As Worksheet Dim qt As QueryTable Dim cn As Object Dim odbcCn As ODBCConnection Dim oledbCn As OLEDBConnection For Each cn In ThisWorkbook.connections If cn.Type = xlConnectionTypeODBC Then Set odbcCn = cn.ODBCConnection odbcCn.SavePassword = False odbcCn.connection = "" odbcCn.CommandText = "" ElseIf cn.Type = xlConnectionTypeOLEDB Then
