  • How can I provide values for non-grouped columns in NHibernate?

    - by ddc0660
    I have a criteria query: Session.CreateCriteria<Sell043Report>() .SetProjection(.ProjectionList() .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.location)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.agent)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.cusip)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.SettlementDate)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.salePrice)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.foreignFx)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.batchNumber)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.origSaleDate)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.planName)) .Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.dateTimeAdded)) .Add(LambdaProjection.Sum<Sell043Report>(r => r.shares)) .Add(LambdaProjection.Sum<Sell043Report>(r => r.netMoney)) .Add(LambdaProjection.Sum<Sell043Report>(r => r.grossMoney)) .Add(LambdaProjection.Sum<Sell043Report>(r => r.taxWithheld)) .Add(LambdaProjection.Sum<Sell043Report>(r => r.fees))) .List<Sell043Report>(); that generates the following SQL: SELECT this_.location as y0_, this_.agent as y1_, this_.cusip as y2_, this_.SettlementDate as y3_, this_.salePrice as y4_, this_.foreignFx as y5_, this_.batchNumber as y6_, this_.origSaleDate as y7_, this_.planName as y8_, this_.dateTimeAdded as y9_, sum(this_.shares) as y10_, sum(this_.netMoney) as y11_, sum(this_.grossMoney) as y12_, sum(this_.taxWithheld) as y13_, sum(this_.fees) as y14_ FROM MIS_IPS_Sell043Report this_ GROUP BY this_.location, this_.agent, this_.cusip, this_.SettlementDate, this_.salePrice, this_.foreignFx, this_.batchNumber, this_.origSaleDate, this_.planName, this_.dateTimeAdded however the Sell043Report table has additional columns than those listed in the SELECT statement so I'm receiving this error when attempting to get a list of Sell043Reports: System.ArgumentException: The value "System.Object[]" is not of type "xyz.Sell043Report" and cannot be used in this generic collection. I suspect the problem is that I'm not selecting all of the columns for a Sell043Report and so it doesn't know how to map the dataset to the object. I'm trying to achieve something like this: SELECT this_.location as y0_, this_.agent as y1_, this_.cusip as y2_, this_.SettlementDate as y3_, this_.salePrice as y4_, this_.foreignFx as y5_, this_.batchNumber as y6_, this_.origSaleDate as y7_, this_.planName as y8_, this_.dateTimeAdded as y9_, sum(this_.shares) as y10_, sum(this_.netMoney) as y11_, sum(this_.grossMoney) as y12_, sum(this_.taxWithheld) as y13_, sum(this_.fees) as y14_, '' as Address1, '' as Address2 // etc FROM MIS_IPS_Sell043Report this_ GROUP BY this_.location, this_.agent, this_.cusip, this_.SettlementDate, this_.salePrice, this_.foreignFx, this_.batchNumber, this_.origSaleDate, this_.planName, this_.dateTimeAdded How can I do this using NHibernate?

    - by ProfK
    I have an ASP.NET Dynamic Data web application, with an entity called ActivationResource. One of the properties of this is a CellPhone field. Now, whenever I open a List or Details view of one of these entities, the cell phone number displays for a moment then disappears. Anyone have any ideas as to the cause of this mysterious behavior?

  • L-Soft LISTSERV TCPGUI Interface for PHP Creation

    - by poolnoodl
    I'm trying to use LISTSERV's "API" in PHP. L-Soft calls this TCPGUI, and essentially, you can request data like over Telnet. To do this, I'm using PHP's TCP socket functions. I've seen this done in other languages but can't quite convert it to PHP. I can connect, I can change set ASCII or BINARY mode. But I can never quite craft the header packet the way I need to authenticate, so I'm thinking I'm messing up my conversion. C: http://www.lsoft.com/manuals/16.0/htmlhelp/advanced%20topics/TCPGUI.html#2334328 $origin = '[email protected]'; $pwd = 'password'; $host = "example.com"; $port = 2306; $email = "[email protected]"; $list = "mailinglist"; $command = "Query $list FOR $email"; $fp = stream_socket_client("tcp://$host:$port", $errno, $errstr, 30); $cmd = $command . " PW=" . $pwd; $len = strlen($cmd); $orglen = strlen($origin); $n = $len + $orglen + 1; $headerPacket[0] = "1"; $headerPacket[1] = "B"; $headerPacket[2] = "\r"; $headerPacket[3] = "\n"; $headerPacket[4] = ord($n / 256); $headerPacket[5] = ord($n + 255); $headerPacket[6] = ord($orglen); for ($i = 0; $i < $orglen; $i++) { $headerPacket[$i + 7] = ord($origin[$i]); } for ($i = 0; $i < $len; $i++) { $cmdPacket[$i] = ord($cmd[$i]); } fwrite($fp, implode($headerPacket)); while (!feof($fp)) { echo fgets($fp, 1024); } Any thoughts on where I'm going wrong? I'd much appreciate it if anyone could point me toward some code to do this, days of googling and searching here on SO has only lead me to examples in other languages. Of course, if you know C (or Java or Perl as linked below in my comment to bypass the spam filter), PHP, and socket programming fairly well, you could probably rewrite the whole of the code in an hour, maybe a few minutes. You'd have my eternal thanks for that.

  • Change video being played in HTML5 video

    - by Krt_Malta
    Hi! I'm using the tags in HTML5 to play a video on a web browser... (and I'm very impressed with this new feature) Is there the functionality to change the video being played through Javascript? Say when I select another video from a list, a Javascript function would be called which would contain something on the lines of MyVideo.VideoLocation = //location of new video to be played. Is this possible please? Thanks and regards, Krt_Malta

  • Can Drupal terms in different Taxonomies be synonymous?

    - by DKinzer
    Let's say Taxonomy_A is associated to Node_Type_A Taxonomy_B is associated to Node_Type_B. AND Both Taxonomy_A and Taxonomy_B have a term called 'yellow'. Is it possible to make terms 'yellow' synonymous, so that if I'm looking at a list of 'yellow' stuff, I'm seeing content of both types (Node_Type_A, and Node_Type_B)?

  • Forced closed only when put alphabetical string in edit text

    - by Abdullah Al Mubarok
    So, I make a checker if an id is in the database or not, the id is in numerical string, the type in database is char(6) though. So this is my code public class input extends Activity{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.input); final EditText edittext = (EditText)findViewById(R.id.editText1); Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub String nopel = edittext.getText().toString(); if(nopel.length() == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ List<NameValuePair> pairs = new ArrayList<NameValuePair>(); pairs.add(new BasicNameValuePair("nopel", nopel)); JSON json_dp = new JSON(); JSONObject jobj_dp = json_dp.getJSON("http://10.0.2.2/KP/pdam/nopel.php", pairs); try { if(jobj_dp.getInt("row") == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ String snopel = jobj_dp.getString("nopel"); String snama = jobj_dp.getString("nama"); String salamat = jobj_dp.getString("alamat"); String sgolongan = jobj_dp.getString("golongan"); Intent i = new Intent(input.this, list.class); i.putExtra("nopel", snopel); i.putExtra("nama", snama); i.putExtra("alamat", salamat); i.putExtra("golongan", sgolongan); startActivity(i); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }); } } the first check is to check if an input is null, it's going right for now, the second check is to check if an id in the database, and it's the problem. When I try some id in numerical value like "0001" or "02013" it's fine, and can run. but when I just got to put "abushd" it forced close. anyone know why I got this?

  • Getting IBindingList Property to sort by

    - by Josh
    I've got a class called DatagridBoundList that implements CollectionBase and IBindingList. The implementation of IBindingList.ApplySort looks like this so far: void IBindingList.ApplySort(PropertyDescriptor property, ListSortDirection direction) { throw new NotSupportedException(); } I'm binding the DatagridBoundList to a DataGridView (winforms). When I reflect over the property parameter, I can't seem to find the name of the actual property that the list needs to be sorted by. What's the trick to finding out the name of the property to sort by?
