說明：
如何透過RESTful WebService來更新後台的資料？


語法：

var strURL = WS URL;

var request = NSMutableURLRequest(URL: NSURL(string: strURL));

request.HTTPMethod = "POST";

        

NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) { (response, data, error) in

            

    if (response != nil)

    {

        var strResponse = NSString(data: data, encoding: NSUTF8StringEncoding);

[C#/Excel PIA] Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 8000401a The server process could not be started because the configured identity is incorrect. Check the username and password.

說明：
使用Excel PIA寫schedule job產出Excel，程式放在64 bits server上，執行出現該錯誤。


解法：
出現此錯誤，主要是COM元件的存取帳戶被設為Interactive，
因此程式執行時，需要有帳戶登入該server。看過網路上的解法，
打開Administrative Tools下的component service -> Computers -> DCOM Config，
找到Microsoft Excel Application或{00024500-0000-0000-C000-000000000046}，
右鍵Properties，找到Security tab或identity tab，將帳戶加進去，
但我找不到Excel Application，試過在command line下mmc comexp.msc /32等方法，還是沒顯示，最後是在登錄檔，HKEY_CLASSES_ROOT\AppID\{00020812-0000-0000-C000-000000000046}，將某個屬性值的Interactive改掉即可。
