  • Declaring variables with New DataSet vs DataSet

    - by eych
    What is the impact of creating variables using: Dim ds as New DataSet ds = GetActualData() where GetActualData() also creates a New DataSet and returns it? Does the original empty DataSet that was 'New'ed just get left in the Heap? What if this kind of code was in many places? Would that affect the ASP.NET process and cause it to recycle sooner?

  • C# and NpgsqlDataAdapter returning a single string instead of a data table

    - by tme321
    I have a postgresql db and a C# application to access it. I'm having a strange error with values I return from a NpgsqlDataAdapter.Fill command into a DataSet. I've got this code: NpgsqlCommand n = new NpgsqlCommand(); n.Connection = connector; // a class member NpgsqlConnection DataSet ds = new DataSet(); DataTable dt = new DataTable(); // DBTablesRef are just constants declared for // the db table names and columns ArrayList cols = new ArrayList(); cols.Add(DBTablesRef.all); //all is just * ArrayList idCol = new ArrayList(); idCol.Add(DBTablesRef.revIssID); ArrayList idVal = new ArrayList(); idVal.Add(idNum); // a function parameter // Select builder and Where builder are just small // functions that return an sql statement based // on the parameters. n is passed to the where // builder because the builder uses named // parameters and sets them in the NpgsqlCommand // passed in String select = SelectBuilder(DBTablesRef.revTableName, cols) + WhereBuilder(n,idCol, idVal); n.CommandText = select; try { NpgsqlDataAdapter da = new NpgsqlDataAdapter(n); ds.Reset(); // filling DataSet with result from NpgsqlDataAdapter da.Fill(ds); // C# DataSet takes multiple tables, but only the first is used here dt = ds.Tables[0]; } catch (Exception e) { Console.WriteLine(e.ToString()); } So my problem is this: the above code works perfectly, just like I want it to. However, if instead of doing a select on all (*) if I try to name individual columns to return from the query I get the information I asked for, but rather than being split up into seperate entries in the data table I get a string in the first index of the data table that looked something like: "(0,5,false,Bob Smith,7)" And the data is correct, I would be expecting 0, then 5, then a boolean, then some text etc. But I would (obviously) prefer it to not be returned as just one big string. Anyone know why if I do a select on * I get a datatable as expected, but if I do a select on specific columns I get a data table with one entry that is the string of the values I'm asking for?

  • Binding Programatically Generated Datasets To Report Viewer

    - by mavera
    Today I researched about reportviewer to use it in my project. As I see the samples and tutorials in the web, We should create an dataset file to Solution Explorer and bind it to report viewer to show data. However I want to create dataset programatically like sample code below. And I want to bind it. Dim ds As New DataSet DB_Gateway.myDataSet("select * from users", ds, "users") How can I do it?

  • Vaadin: Downloaded file has whole path as file name

    - by javydreamercsw
    I have a download action implemented on my Vaadin application but for some reason the downloaded file has the original file's full path as the file name. Any idea? You can see the code on this post. Edit: Here's the important part of the code: package com.bluecubs.xinco.core.server.vaadin; import com.bluecubs.xinco.core.server.XincoConfigSingletonServer; import com.vaadin.Application; import com.vaadin.terminal.DownloadStream; import com.vaadin.terminal.FileResource; import java.io.*; import java.net.URLEncoder; import java.util.UUID; import java.util.logging.Level; import java.util.logging.Logger; import java.util.zip.CRC32; import java.util.zip.CheckedInputStream; /** * * @author Javier A. Ortiz Bultrón<[email protected]> */ public class FileDownloadResource extends FileResource { private final String fileName; private File download; private File newFile; public FileDownloadResource(File sourceFile, String fileName, Application application) { super(sourceFile, application); this.fileName = fileName; } protected void cleanup() { if (newFile != null && newFile.exists()) { newFile.delete(); } if (download != null && download.exists() && download.listFiles().length == 0) { download.delete(); } } @Override public DownloadStream getStream() { try { //Copy file to directory for downloading InputStream in = new CheckedInputStream(new FileInputStream(getSourceFile()), new CRC32()); download = new File(XincoConfigSingletonServer.getInstance().FileRepositoryPath + System.getProperty("file.separator") + UUID.randomUUID().toString()); newFile = new File(download.getAbsolutePath() + System.getProperty("file.separator") + fileName); download.mkdirs(); OutputStream out = new FileOutputStream(newFile); newFile.deleteOnExit(); download.deleteOnExit(); byte[] buf = new byte[1024]; int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } in.close(); out.close(); final DownloadStream ds = new DownloadStream( new FileInputStream(newFile), getMIMEType(), fileName); ds.setParameter("Content-Disposition", "attachment; filename=" + URLEncoder.encode(fileName, "utf-8")); ds.setCacheTime(getCacheTime()); return ds; } catch (final FileNotFoundException ex) { Logger.getLogger(FileDownloadResource.class.getName()).log(Level.SEVERE, null, ex); return null; } catch (IOException ex) { Logger.getLogger(FileDownloadResource.class.getName()).log(Level.SEVERE, null, ex); return null; } } } I already debugged and verified that fileName only contains the file's name not the whole path.

  • how to generate the "create table" sql statement for an existing table in postgreSQL

    - by Raja
    I have a table created long ago in postgreSQL. Now i want to look at the sql statement used to create it but cannot figure it out. Also when i do the \dS+ tablename it says table not found, but \dt+ tablename is working fine. The \dS+ lists all the table names owned by the root postgres user and doesn't show up tables that i created with my user account. Any help is greatly appreciated. Thanks

  • Issues querying Access '07 database in C#

    - by Kye
    I'm doing a .NET unit as part of my studies. I've only just started, with a lecturer that as kinda failed to give me the most solid foundation with .NET, so excuse the noobishness. I'm making a pretty simple and generic database-driven application. I'm using C# and I'm accessing a Microsoft Access 2007 database. I've put the database-ish stuff in its own class with the methods just spitting out OleDbDataAdapters that I use for committing. I feed any methods which preform a query a DataSet object from the main program, which is where I'm keeping the data (multiple tables in the db). I've made a very generic private method that I use to perform SQL SELECT queries and have some public methods wrapping that method to get products, orders.etc (it's a generic retail database). The generic method uses a separate Connect method to actually make the connection, and it is as follows: private static OleDbConnection Connect() { OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\Temp\db.accdb"); return conn; } The generic method is as follows: private static OleDbDataAdapter GenericSelectQuery( DataSet ds, string namedTable, String selectString) { OleDbCommand oleCommand = new OleDbCommand(); OleDbConnection conn = Connect(); oleCommand.CommandText = selectString; oleCommand.Connection = conn; oleCommand.CommandType = CommandType.Text; OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter.SelectCommand = oleCommand; adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; adapter.Fill(ds, namedTable); return adapter; } The wrapper methods just pass along the DataSet that they received from the main program, the namedtable string is the name of the table in the dataset, and you pass in the query you wish to make. It doesn't matter which query I give it (even something simple like SELECT * FROM TableName) I still get thrown an OleDbException, stating that there was en error with the FROM clause of the query. I've just resorted to building the queries with Access, but there's still no use. Obviously there's something wrong with my code, which wouldn't actually surprise me. Here are some wrapper methods I'm using. public static OleDbDataAdapter GetOrderLines(DataSet ds) { OleDbDataAdapter adapter = GenericSelectQuery( ds, "orderlines", "SELECT OrderLine.* FROM OrderLine;"); return adapter; } They all look the same, it's just the SQL that changes.

  • How can I download all files of a specific type from a website using PHP?

    - by CheeseConQueso
    I want to get all midi (*.mid) files from a site that's set up pretty simple in terms of directory tree structure. I wish we had wget installed here, but that's another party.... The site is VGMusic.com and the path containing all of the midi files is: http://www.vgmusic.com/music/console/nintendo/nes/ I tried glob'ing it out, but I suppose that glob only works locally? Here is what I wrote to try to make it happen (doesn't work.. obviously..): <?php echo 'not a blizzard<br>'; foreach(glob('http://www.vgmusic.com/music/console/nintendo/nes/*.mid') as $filename) { echo $filename.'<br>'; //$newfile = 'http://www.mydomain.com/nes/'.$filename; //copy($filename, $newfile) } ?> I tried it also without the http:// in there with no luck.

Has anyone used any of the "game development" for kids softwares out there? Can you recommend any?

  • SmartGWT TreeGrid, adding and editing

    - by Banang
    I'm trying to programmatically add a new TreeNode to a TreeGrid, and then turn on editing for the newly added node. This is my data source: DataSource ds = new DataSource(); DataSourceTextField idField = new DataSourceTextField("key", "Id"); DataSourceTextField nameField = new DataSourceTextField("name", "Name"); DataSourceTextField keyField = new DataSourceTextField("id", "Key"); keyField.setPrimaryKey(true); ds.setFields(idField, keyField, nameField); ds.setClientOnly(true); My fields: TreeGridField name = new TreeGridField("name", "Name"); TreeGridField id = new TreeGridField("id", "Id"); TreeGridField key = new TreeGridField("key", "Key"); key.setHidden(true); id.setHidden(true); And my code for adding a new record: TreeNode parent = (TreeNode) treeGrid.getSelectedRecord(); if (parent == null) parent = treeGrid.getData().getRoot(); Tree data = treeGrid.getData(); node = data.add(node, parent); Now, how on earth do I switch on editing for the added node? I've tried startEditing(), but that defaults to the first node, and I don't see any way of obtaining the row number for the newly added node, which would allow me to use startEditing(rowNum, colNum, suppressFocus). Using startEditNew() is not an option for many reasons, mainly because that method adds the new node to the bottom of the tree, which doesn't work at all with my app. How do I do this? Grateful for any help you guys can give me.

  • Assert.AreEqual() Exception in VS2010

    - by Tom Miller
    I am fairly new to unit testing and am using VS2010 to develop in and run my tests. I have a simple test, illustrated below, that simply compares 2 System.Data.DataTableReader objects. I know that they are equal as they are both created using the same object types, the same input file and I have verified that the objects "look" the same. I realize I may be dealing with a couple of issues, one being whether or not this is the proper use of Assert.AreEqual or even the proper way to test this scenario, and the other being the main issue I am dealing with which is why this test fails with this exception: Failed 00:00:00.1000660 0 Assert.AreEqual failed. Expected:<System.Data.DataTableReader>. Actual:<System.Data.DataTableReader>. Here is the unit test code that is failing: public void EntriesTest() { AuditLog target = new AuditLog(); target.Init(); DataSet ds = new DataSet(); ds.ReadXml(TestContext.DataRow["AuditLogPath"].ToString()); DataTableReader expected = ds.Tables[0].CreateDataReader(); DataTableReader actual = target.Entries.Tables[0].CreateDataReader(); Assert.AreEqual<DataTableReader>(expected, actual); } Any help would be greatly appreciated!

  • Problem with asp.net function syntax (not returning values correctly)

    - by Phil
    I have an active directory search function: Function GetAdInfo(ByVal ADDN As String, ByVal ADCommonName As String, ByVal ADGivenName As String, ByVal ADStaffNum As String, ByVal ADEmail As String, ByVal ADDescription As String, ByVal ADTelephone As String, ByVal ADOffice As String, ByVal ADEmployeeID As String) As String Dim netBIOSname As String = Me.Request.LogonUserIdentity.Name Dim sAMAccountName As String = netBIOSname.Substring(netBIOSname.LastIndexOf("\"c) + 1) Dim defaultNamingContext As String Using rootDSE As DirectoryServices.DirectoryEntry = New DirectoryServices.DirectoryEntry("LDAP://RootDSE") defaultNamingContext = rootDSE.Properties("defaultNamingContext").Value.ToString() End Using Using searchRoot As DirectoryServices.DirectoryEntry = _ New DirectoryServices.DirectoryEntry("LDAP://" + defaultNamingContext, _ "kingkong", "kingkong", DirectoryServices.AuthenticationTypes.Secure) Using ds As DirectoryServices.DirectorySearcher = New DirectoryServices.DirectorySearcher(searchRoot) ds.Filter = String.Format("(&(objectClass=user)(objectCategory=person)(sAMAccountName={0}))", sAMAccountName) Dim sr As DirectoryServices.SearchResult = ds.FindOne() 'If sr.Properties("displayName").Count = 0 Then whatever = string.empty '' (how to check nulls when required) ' End If ADDN = (sr.Properties("displayName")(0).ToString()) ADCommonName = (sr.Properties("cn")(0).ToString()) ADGivenName = (sr.Properties("givenname")(0).ToString()) ADStaffNum = (sr.Properties("sn")(0).ToString()) ADEmail = (sr.Properties("mail")(0).ToString()) ADDescription = (sr.Properties("description")(0).ToString()) ADTelephone = (sr.Properties("telephonenumber")(0).ToString()) ADOffice = (sr.Properties("physicalDeliveryOfficeName")(0).ToString()) ' ADEmployeeID = (sr.Properties("employeeID")(0).ToString()) End Using End Using Return ADDN Return ADCommonName Return ADGivenName Return ADStaffNum Return ADEmail Return ADDescription Return ADTelephone Return ADOffice ' Return ADEmployeeID 'have commented out employee id as i dont have one so it is throwing null errors. ' im not ready to put labels on the frontend or catch this info yet End Function The function appears to work, as when I put a breakpoint at the end, the variables such as ADDN do have the correct values. Then I call the function in my page_load like this: GetAdInfo(ADDN, ADCommonName, ADGivenName, ADStaffnum, ADEmail, ADDescription, ADTelephone, ADOffice, ADEmployeeID) Then I try to response.write out one of the vars to test like this: Response.Write(ADDN) But the value is empty. Please can someone tell me what I am doing wrong. Thanks
