  - by Surya sasidhar

  I get this error (file is being used by another process). Actually I write the code in a button click event like this, i am saving the excel file in a file using file upload, immediately i am fetching the file which i was save just now there i am getting this error. in my point of view i think it take time to save the excel file in that file. this is my code: FileUpload1.PostedFile.SaveAs(Server.MapPath("~/User/Excel/" + name.ToString() + ".xls")); string s = Server.MapPath("~/user/excel/" + name.ToString() + ".xls"); OleDbConnection DBConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + s.ToString() + ";" + "Extended Properties=\"Excel 8.0;HDR=Yes\""); DBConnection.Open(); string SQLString = "SELECT * FROM Contacts"; OleDbCommand DBCommand = new OleDbCommand(SQLString, DBConnection); IDataReader DBReader = DBCommand.ExecuteReader(); mygridOut.DataSource = DBReader; mygridOut.DataBind(); and i am getting error like this: because it is being used by another process.

• TableView on Tab Bar Application ? Application is crashing.

  - by Andrei

  Steps to reproduce: 1. Create a Tab Bar Application called "TestApp" 2. Add new file, a UIViewController subclass with a XIB user interface called "Table" 3. Open up MainWindows.xib, click on the Second tab bar item and in Inspector change the NIB Name from "SecondView" to "Table". Save and close. 4. Open up Table.xib and drag a TableView on top of the view. Now link the dataSource and delegate outlets of the TableView to the Table.xib File's Owner. 5. Add the following code to Table.m: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSLog(@"Returning num sections"); return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"Returning num rows"); return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Trying to return cell"); static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.text = @"Hello"; NSLog(@"Returning cell"); return cell; } 6.Run the application and select the Second tab bar item. If I start with a View-based application, add a TableView to it, link the outlets to the File's owner and add that piece of code it all works just fine. What am I doing wrong ? Why is the application crashing ?

• Binding the selected value from a combobox to a member of a class.

  - by CM

  I have a combobox that is bound to a an instance of a class. I need to get the user's selection ID of the combobox and set a class property equal to it. For example, here is the class: public class robot { private string _ID; private string _name; private string _configFile; [XmlElement("hardware")] public hardware[] hardware; public string ID { get { return _ID; } set { _ID = value; } } public string name { get { return _name; } set { _name = value; } } public string configFile { get { return _configFile; } set { _configFile = value; } } } Now here is the code to bind the combobox to an instance of that class. This display's the name of each robot in the array in the combobox. private void SetupDevicesComboBox() { robot[] robot = CommConfig.robot; cmbDevices.DataSource = robot; cmbDevices.DisplayMember = "name"; cmbDevices.ValueMember = "ID"; } But now I can't seem to take what the user selects and use it. How do I use the "ID" of what the user select's from the combobox? Settings.selectedRobotID = cmbDevices.ValueMember; //This just generates "ID" regardless of what is selected. I also tried Settings.selectedRobotID = cmbDevices.SelectedItem.ToString(); //This just generates "CommConfig.robot" Thanks

• Accessing my own datalayer using RIA & Silverlight

  - by Norsten

  Is it possible for me to connect to my own data provide via WCF RIA services? I've created a small datalayer that connnects to DynamicAX datasource. I would like to use Silverlight 4 & RIA service to access that datalayer. At it's most basic -I've done the following... 1) I've added an empty domainclass to the webproject and in that class I created a simple method to return a string... [EnableClientAccess()] public class ProjectService : DomainService { public string TestViaRIA() { return "Hello!"; } } 2) I then added reference to the web project in my silvelight class and created a bit of code to try and invoke the method... using ProjectApp.Web; namespace ProjectApp.Views { public partial class ProjectControl : UserControl { public ProjectControl() { InitializeComponent(); ProjectContext ctx = new ProjectContext(); var x = ctx.TestViaRIA(); testTextBox.Text = x.ToString(); } } } the returned value is "{System.ServiceModel.DomainServices.Client.InvokeOperation}". I'm obviously doing something wrong here and I would appreciate some guidance on how I can achive this. Thanks in advance

• Storing records in a dropdownlist from DB without using LINQ Data source

  - by user1318369

  I have a website for dance academy where Users can register and add/drop dance classes. In the web page to drop a particular dance, for a particular user, the dropdown displays her registered dances. Now I want to delete one of the dances from the list. So i'll remove the row from the table and also from the dropdownlist. The problem is that everytime the item with the lowest ID (index) is getting deleted, no matter which one the user selects. I think I am storing the DataTextField and DataValueField for the dropdown incorrectly. Can someone please help me out? The code is: private void PopulateDanceDropDown() { var registereddanceList = from dd in context.DANCER_AND_DANCE where dd.UserId == dancerId select new { Text = dd.DanceName, Value = dd.DanceId }; dances.DataSource = registereddanceList; dances.DataTextField = "Text"; dances.DataValueField = "Value"; dances.DataBind(); } protected void dropthedance(object o, EventArgs e) { String strDataValueField = dances.SelectedItem.Value; int danceIDFromDropDown = Convert.ToInt32(strDataValueField); var dancer_dance = from dd in context.DANCER_AND_DANCE where dd.DanceId == danceIDFromDropDown select dd; foreach (var dndd in dancer_dance) { context.DANCER_AND_DANCE.DeleteOnSubmit(dndd); } try { context.SubmitChanges(); } catch (Exception ex) { Console.WriteLine(ex); } PopulateDanceDropDown(); }

• Load Empty Database table

  - by john White

  I am using SQLexpress and VS2008. I have a DB with a table named "A", which has an IdentitySpecification column named ID. The ID is auto-incremented. Even if the row is deleted, the ID still increases. After several data manipulation, the current ID has reached 15, for example. When I run the application if there's at least 1 row: if I add a new row, the new ID is 16. Everything is fine. If the table is empty (no row): if I add a new row, the new ID is 0, which is an error (I think). And further data manipulation (eg. delete or update) will result in an unhandled exception. Has anyone encountered this? PS. In my table definition, the ID has been selected as follow: Identity Increment = 1; Identity Seed =1; The DB load code is: dataSet = gcnew DataSet(); dataAdapter->Fill(dataSet,"A"); dataTable=dataSet->Tables["A"]; dbConnection->Open(); The Update button method dataAdapter->Update(dataSet,"tblInFlow"); dataSet->AcceptChanges(); dataTable=dataSet->Tables["tblInFlow"]; dataGrid->DataSource=dataTable; If I press Update: if there's at least a row: the datagrid view updates and shows the table correctly. if there's nothing in the table (no data row), the Add method will add a new row, but from ID 0. If I close the program and restart it again: the ID would be 16, which is correct. This is the add method row=dataTable->NewRow(); row["column1"]="something"; dataTable->Rows->Add(row); dataAdapter->Update(dataSet,"A"); dataSet->AcceptChanges(); dataTable=dataSet->Tables["A"];

• What is a better, cleaner way of using List<T>

  - by Tim Meers

  I'm looking to implement a few nicer ways to use List in a couple of apps I'm working on. My current implementation looks like this. MyPage.aspx.cs protected void Page_Load(object sender, EventArgs e) { BLL.PostCollection oPost = new BLL.PostCollection(); oPost.OpenRecent(); rptPosts.DataSource = oArt; rptPosts.DataBind(); } BLL Class(s) public class Post { public int PostId { get; set; } public string PostTitle { get; set; } public string PostContent { get; set; } public string PostCreatedDate { get; set; } public void OpenRecentInitFromRow(DataRow row) { this.PostId = (int) row["id"]; this.PostTitle = (string) row["title"]; this.PostContent = (string) row["content"]; this.PostCreatedDate = (DateTime) row["createddate"]; } } public class PostCollection : List<Post> { public void OpenRecent() { DataSet ds = DbProvider.Instance().Post_ListRecent(); foreach (DataRow row in ds.Tables[0].Rows) { Post oPost = new Post(); oPost.OpenRecentInitFromRow(row); Add(oPost); } } } Now while this is working all well and good, I'm just wondering if there is any way to improve it, and just make it cleaner that having to use the two different classes do to something I think can happen in just one class or using an interface.

And then when it gets submitted it fails cause it doesnt match the mapname in question. the results look like this " 320-197" So what is causing this? if i run the jsp page alone also get normal results for example 372-146, 376-146, 372-149, 368-149, 376-149, 380-149, 380-152, 376-152, 372-152, 368-152, 368-155, 376-155, 372-155, 380-155, 368-158, 380-158, 376-158, 372-158 thanks in advance

• How to compare date from database using C#?

  - by user1490374

  I would like to compare the date selected from the database (every entry in EndDate) and compare them with today date. Is there any way to do this programmatically? Like extracting the dates and comparing them individually? I need this because I need to update the status for the table. string username; username = HttpContext.Current.User.Identity.Name; string date = DateTime.Now.ToString("MM/dd/yyyy"); txtDate.Text = date; SqlConnection conn1 = new SqlConnection("Data Source=mydatasource\\sqlexpress;" + "Initial Catalog = Suite2; Integrated Security =SSPI"); SqlDataAdapter adapter; string end; end = "SELECT EndDate FROM Table_Message WHERE username = '" + username + "'"; adapter = new SqlDataAdapter(end, conn1); conn1.Open(); DataSet ds = new DataSet(); adapter.Fill(ds); //Execute the sql command GridView2.DataSource = ds; GridView2.DataBind(); conn1.Close();

  - by lmmortal

  I have informix 11.5 running in my Win-2003 box and few databases running in it. System databases have locale en_us.819 My custom databases have locale en_us.57372 (UTF8). There is also application deployed to JBoss 4.0.2 which has few datasources configured for those custom databases. <local-tx-datasource> <jndi-name>InformixDS</jndi-name> <connection-url>jdbc:informix-sqli://@database.server@:@database.port@/tcs_catalog:[email protected]@</connection-url> <driver-class>com.informix.jdbc.IfxDriver</driver-class> <user-name>@database.username@</user-name> <password>@database.password@</password> <new-connection-sql>set lock mode to wait 5</new-connection-sql> <check-valid-connection-sql>select '1' from dual</check-valid-connection-sql> <metadata> <type-mapping>InformixDB</type-mapping> </metadata> I'm logged in as Administrator and when I start JBoss the following error is shown Caused by: java.sql.SQLException: Database locale information mismatch. at com.informix.util.IfxErrMsg.getSQLException(IfxErrMsg.java:373) at com.informix.jdbc.IfxSqli.a(IfxSqli.java:3208) at com.informix.jdbc.IfxSqli.E(IfxSqli.java:3518) at com.informix.jdbc.IfxSqli.dispatchMsg(IfxSqli.java:2353) at com.informix.jdbc.IfxSqli.receiveMessage(IfxSqli.java:2269) at com.informix.jdbc.IfxSqli.executeOpenDatabase(IfxSqli.java:1786) at com.informix.jdbc.IfxSqliConnect.<init>(IfxSqliConnect.java:1327) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:501) at com.informix.jdbc.IfxDriver.connect(IfxDriver.java:254) at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:151) ... 160 more Caused by: java.sql.SQLException at com.informix.util.IfxErrMsg.getSQLException(IfxErrMsg.java:373) at com.informix.jdbc.IfxSqli.E(IfxSqli.java:3523) ... 170 more DB_LOCALE and CLIENT_LOCALE are set to en_us.utf8 for Administrator. When I set in Server Studio DB_LOCALE and CLIENT_LOCALE to en_us.utf8 I can connect my databases. Where should I set DB_LOCALE and CLIENT_LOCALE to avoid this Database locale information mismatch error? Thanks.

• Script to check a shared Exchange calendar and then email detail

  - by SJN

  We're running Server and Exchange 2003 here. There's a shared calendar which HR keep up-to-date detailing staff who are on leave. I'm looking for a VB Script (or alternate) which will extract the "appointment" titles of each item for the current day and then email the detail to a mail group, in doing so notifying the group with regard to which staff are on leave for the day. The resulting email body should be: Staff on leave today: Mike Davis James Stead @Paul Robichaux - ADO is the way I went for this in the end, here are the key component for those interested: Dim Rs, Conn, Url, Username, Password, Recipient Set Rs = CreateObject("ADODB.Recordset") Set Conn = CreateObject("ADODB.Connection") 'Configurable variables Username = "Domain\username" ' AD domain\username Password = "password" ' AD password Url = "file://./backofficestorage/domain.com/MBX/username/Calendar" 'path to user's mailbox and folder Recipient = "[email protected]" Conn.Provider = "ExOLEDB.DataSource" Conn.Open Url, Username, Password Set Rs.ActiveConnection = Conn Rs.Source = "SELECT ""DAV:href"", " & _ " ""urn:schemas:httpmail:subject"", " & _ " ""urn:schemas:calendar:dtstart"", " & _ " ""urn:schemas:calendar:dtend"" " & _ "FROM scope('shallow traversal of """"') " Rs.Open Rs.MoveFirst strOutput = "" Do Until Rs.EOF If DateDiff("s", Rs.Fields("urn:schemas:calendar:dtstart"), date) >= 0 And DateDiff("s", Rs.Fields("urn:schemas:calendar:dtend"), date) < 0 Then strOutput = strOutput & "<p><font size='2' color='black' face='verdana'><b>" & Rs.Fields("urn:schemas:httpmail:subject") & "</b><br />" & vbCrLf strOutput = strOutput & "<b>From: </b>" & Rs.Fields("urn:schemas:calendar:dtstart") & vbCrLf strOutput = strOutput & "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<b>To: </b>" & Rs.Fields("urn:schemas:calendar:dtend") & "<br /><br />" & vbCrLf End If Rs.MoveNext Loop Conn.Close Set Conn = Nothing Set Rec = Nothing After that, you can do what you like with srtOutput, I happened to use CDO to send an email: Set objMessage = CreateObject("CDO.Message") objMessage.Subject = "Subject" objMessage.From = "[email protected]" objMessage.To = Recipient objMessage.HTMLBody = strOutput objMessage.Send S
