• Android table width queries

  - by user1653285

  I have a table layout (code below), but I have am having a bit of a problem with the width of the cells. The picture below shows the problem. There should be a white border on the right hand side of the screen. I also want the text "Auditorium" not to wrap onto a new line (I would prefer that "13th -" get put onto the new line instead, I don't want to put \n in there because then it would mean it goes onto a new line at that point on bigger screens/landscape view). How can I fix those two problems? <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#013567" > <TableLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:shrinkColumns="*" android:stretchColumns="*" > <TableRow android:layout_width="match_parent" android:layout_height="wrap_content" > <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/textlines" android:gravity="center" android:text="@string/meeting_5" android:textColor="#fff" > </TextView> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/textlines" android:gravity="center" android:text="@string/meeting_5_date" android:textColor="#fff" > </TextView> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/textlines" android:gravity="center" android:text="@string/meeting_5_location" android:textColor="#fff" > </TextView> </TableRow> <TableRow android:layout_width="match_parent" android:layout_height="wrap_content" > <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/textlines" android:gravity="center" android:text="@string/AGM" android:textColor="#fff" > </TextView> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/textlines" android:gravity="center" android:text="@string/AGM_date" android:textColor="#fff" > </TextView> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/textlines" android:gravity="center" android:text="@string/AGM_location" android:textColor="#fff" > </TextView> </TableRow> </TableLayout>

• Calculations in a table of data

  - by Christian W

  I have a table of data with survey results, and I want to do certain calculations on this data. The datastructure is somewhat like this: ____________________________________________________________________________________ | group |individual | key | key | key | | | |subkey|subkey|subkey|subkey|subkey|subkey|subkey|subkey|subkey| | | |q|q|q |q |q |q|q|q |q|q|q |q |q |q|q|q |q|q|q |q |q |q|q|q | |-------|-----------|-|-|--|--|---|-|-|--|-|-|--|--|---|-|-|--|-|-|--|--|---|-|-|--| | 1 | 0001 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | | 1 | 0002 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | | 1 | 0003 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | | 2 | 0004 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | | 2 | 0005 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | | 3 | 0006 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | | 4 | 0007 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 |1|7|5 |1 |3 |1|4|1 | ------------------------------------------------------------------------------------ Excuse my poor ascii skills... So, every individual belongs to a group, and has answered some questions. These questions are always grouped in keys and subkeys. Is there any simple method to calculate averages, deviations and similar based on the groupings. Something like public float getAverage(int key, int individual); float avg = getAverage(5,7); I think what I'm asking is what would be the best way to structure the data in C# to make it as easy as possible to work with? I have started making classes for every entity, but I got confused somewhere and something stopped working. So before I continue along this path, I was wondering if there are any other, better, ways of doing this? (Every individual can also have describing variables, like agegroup and such, but that's not important for the base functionality.) Our current solution does all calculations inline in the queries when requesting the data from the database. This works, but it's slow and the number of queries equals questions * individuals + keys * individuals, which could be alot if individual queries. Any suggestions?

• Adding rows with linq trouble with reference table

  - by Laurence Burke

  I am adding a new address and I know the structure as AddressID = PK and all other entities are non nullable. Now on insert of a new row the addrID Pk is autogened and I am wondering if I would have to get that to create a new row in the referencing table EmployeeAddress or does that automatically get generated also. also I want to be able to repopulate the dropdownlist that lists the current employee's addresses with the newly created address. static uint _curEmpID; protected void btnAdd_Click(object sender, EventArgs e) { if (txtZip.Text != "" && txtAdd1.Text != "" && txtCity.Text != "") { TestDataClassDataContext dc = new TestDataClassDataContext(); Address addr = new Address() { AddressLine1 = txtAdd1.Text, AddressLine2 = txtAdd2.Text, City = txtCity.Text, PostalCode = txtZip.Text, StateProvinceID = Convert.ToInt32(ddlState.SelectedValue) }; dc.Addresses.InsertOnSubmit(addr); lblSuccess.Visible = true; lblErrMsg.Visible = false; dc.SubmitChanges(); // // TODO: insert new row in EmployeeAddress to reference CurEmp to newly created address // SetAddrList(); } else { lblErrMsg.Text = "Invalid Input"; lblErrMsg.Visible = true; } } protected void ddlAddList_SelectedIndexChanged(object sender, EventArgs e) { lblErrMsg.Visible = false; lblSuccess.Visible = false; TestDataClassDataContext dc = new TestDataClassDataContext(); dc.ObjectTrackingEnabled = false; if (ddlAddList.SelectedValue != "-1") { var addr = (from a in dc.Addresses where a.AddressID == Convert.ToInt32(ddlAddList.SelectedValue) select a).FirstOrDefault(); txtAdd1.Text = addr.AddressLine1; txtAdd2.Text = addr.AddressLine2; txtCity.Text = addr.City; txtZip.Text = addr.PostalCode; ddlState.SelectedValue = addr.StateProvinceID.ToString(); btnSubmit.Visible = true; btnAdd.Visible = false; } else { txtAdd1.Text = ""; txtAdd2.Text = ""; txtCity.Text = ""; txtZip.Text = ""; btnAdd.Visible = true; btnSubmit.Visible = false; } } protected void SetAddrList() { TestDataClassDataContext dc = new TestDataClassDataContext(); dc.ObjectTrackingEnabled = false; var addList = from addr in dc.Addresses from eaddr in dc.EmployeeAddresses where eaddr.EmployeeID == _curEmpID && addr.AddressID == eaddr.AddressID select new { AddValue = addr.AddressID, AddText = addr.AddressID, }; ddlAddList.DataSource = addList; ddlAddList.DataValueField = "AddValue"; ddlAddList.DataTextField = "AddText"; ddlAddList.DataBind(); ddlAddList.Items.Add(new ListItem("<Add Address>", "-1")); } OK I am hoping that I did not include too much code. I would really appreciate any other comments about I could otherwise improve this code in any other ways also.

• linq to sql with nservicebus table lock issue

  - by IGoor

  I am building a system using NServiceBus and my DataLayer is using Linq 2 SQL. The system is made up of 2 services. Service1 receives messages from NSB. It will query Table1 in my database and inserts a record into Table1 If a certain condition is met a new NSB message is sent to the 2nd service Service2 will update records also in Table1 when it receives messages from Service1 and it does some other non database related work. Service2 is a long running process. The problem I am having is the moment Service2 updates a record in Table1, the table is locked. The lock seems to be in place until Service2 has completed all it is processing. i.e. The lock is not released after my datacontext is disposed. This causes the query in Service1 to timeout. Once Service2 completes processing, Service1 resumes processing again without problem. So for example Service1 code may look like: int x =0; using (DataContext db = new DataContext()) { x = (from dp in db.Table1 select dp).Count(); // this line will timeout while service2 is processing Table1 t = new Table1(); t.Data = "test"; db.Table1.InsertOnSubmit(t); db.SubmitChanges(); } if(x % 50 == 0) CallService2(); The code in service2 may look like: using (DataContext db = new DataContext()) { Table1 t = db.Table1.Where(t => t.id == myId); t.Data = "updated"; db.SubmitChanges(); } // I would have expected the lock to have been released at this point, but this is not the case. DoSomeLongRunningTasks(); // lock will be released once service2 exits I don't understand why the lock is not released when the datacontext is disposed in Service2. To get around the problem I have been calling: db.ExecuteCommand("SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED"); and this works, but I am not happy using it. I want to solve this problem properly. Has any one experienced this sort of problem before and does any one know how to solve it? Why is the lock not released after the datacontext has been disposed? Thanks in advance. p.s. sorry for the extremely long post.

• Reading column header and column values of a data table using LAMBDA(C#3.0)

  - by Newbie

  Consider the folowing where I am reading the data table values and writing to a text file using (StreamWriter sw = new StreamWriter(@"C:\testwrite.txt",true)) { DataPreparation().AsEnumerable().ToList().ForEach(i => { string col1 = i[0].ToString(); string col2 = i[1].ToString(); string col3 = i[2].ToString(); string col4 = i[3].ToString(); sw.WriteLine( col1 + "\t" + col2 + "\t" + col3 + "\t" + col4 + Environment.NewLine ); }); } The data preparation function is as under private static DataTable DataPreparation() { DataTable dt = new DataTable(); dt.Columns.Add("Col1", typeof(string)); dt.Columns.Add("Col2", typeof(int)); dt.Columns.Add("Col3", typeof(DateTime)); dt.Columns.Add("Col4", typeof(bool)); for (int i = 0; i < 10; i++) { dt.Rows.Add("String" + i.ToString(), i, DateTime.Now.Date, (i % 2 == 0) ? true : false); } return dt; } It is working fine. Now in the above described program, it is known to me the Number of columns and the column headers. How to achieve the same in case when the column headers and number of columns are not known at compile time using the lambda expression? I have already done that which is as under public static void WriteToTxt(string directory, string FileName, DataTable outData, string delimiter) { FileStream fs = null; StreamWriter streamWriter = null; using (fs = new FileStream(directory + "\\" + FileName + ".txt", FileMode.Append, FileAccess.Write)) { try { streamWriter = new StreamWriter(fs); streamWriter.BaseStream.Seek(0, SeekOrigin.End); streamWriter.WriteLine(); DataTableReader datatableReader = outData.CreateDataReader(); for (int header = 0; header < datatableReader.FieldCount; header++) { streamWriter.Write(outData.Columns[header].ToString() + delimiter); } streamWriter.WriteLine(); int row = 0; while (datatableReader.Read()) { for (int field = 0; field < datatableReader.FieldCount; field++) { streamWriter.Write(outData.Rows[row][field].ToString() + delimiter); } streamWriter.WriteLine(); row++; } } catch (Exception ex) { throw ex; } } } I am using C#3.0 and framework 3.5 Thanks in advance

• Table prefix for MySqlMembershipProvider

• Android - Retrieve all data from a SQLite table row

  - by Paul

  I have searched and cannot find an answer to my issue so i hope i am not completely barking up the wrong tree (so to speak). I am new to android and have started to create an app. My app on one screen creates and adds entries to a SQLite database using public class DatabaseHandler extends SQLiteOpenHelper and this all appears to work. I retrieve all the data and populate it into a grid, again this now works. My issue is I am unable to retrieve one complete line from the grid. I populate/display the grid with the following code. I have cut a lot out as the grid is made in stages, header, blank lines etc but the grid does display as I want. The id’s work as when I touch a line it displays its unique id. The onClick is right at the end and when I use getText() instead of getID() all it returns is the data in the labelDate. How do I retrieve all the labels as listed below? TextView labelDATE = new TextView(this); TextView labelCP = new TextView(this); TextView labelBG = new TextView(this); TextView labelQA = new TextView(this); TextView labelCN = new TextView(this); TextView labelKT = new TextView(this); TextView[] tvArray = {labelDATE, labelCP, labelBG, labelQA, labelCN, labelKT}; labelDATE.setText(re.getTime()); labelCP.setText(re.getCP()); labelBG.setText(re.getBG()); labelQA.setText(re.getQA()); labelCN.setText(re.getCN()); labelKT.setText(re.getKT()); for (TextView tv : tvArray) { tv.setTextColor(Color.WHITE); tv.setId(200+count); tr.setOnClickListener(this); tr.addView(tv); } //add this to the table row tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); public void onClick(View v) { if (v instanceof TableRow) { TableRow row = (TableRow) v; TextView child = (TextView) row.getChildAt(0); Toast toast = Toast.makeText(this, String.valueOf(child.getId()), Toast.LENGTH_SHORT); toast.show(); } } I can supply all the code for the grid creation if required. Thanks for any help.

• plus minus table View cell

  - by user1748387

  I have the following code - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; UIImage * i1 = [UIImage imageNamed: @"inc_01.png"]; UIImage * i2 = [UIImage imageNamed: @"inc_02.png"]; UIImage * i3 = [UIImage imageNamed: @"inc_04.png"]; UIImage * i5 = [UIImage imageNamed: @"inc_05.png"]; UIImage * i6 = [UIImage imageNamed: @"inc_06.png"]; UIImage * i7 = [UIImage imageNamed: @"inchd.png"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } if(indexPath.row == 0) { UIImageView * header= [[UIImageView alloc] initWithImage: i1]; cell.backgroundView = header; // Configure the cell… } else if (indexPath.row == 2) { UIImageView *backgroundCellImage=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 280, 11)]; backgroundCellImage.image=[UIImage imageNamed:@"inc_06.png"]; [cell.contentView addSubview:backgroundCellImage]; } else { // Configure the cell… UIImageView *imageView = [[UIImageView alloc] initWithImage: i3]; cell.textLabel.text = @"text"; UIImageView *backgroundCellImage=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 57, 46)]; backgroundCellImage.image=[UIImage imageNamed:@"inc_02.png"]; UIImageView *backgroundCellImage2=[[UIImageView alloc] initWithFrame:CGRectMake(223, 0, 57, 46)]; backgroundCellImage2.image=[UIImage imageNamed:@"inc_04.png"]; UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(57, 0, 166, 46)]; label.text = @"wow"; [cell.contentView addSubview:backgroundCellImage]; [cell.contentView addSubview:backgroundCellImage2]; [cell.contentView addSubview:label]; } return cell; } that basically creates a table view and puts an image to the left and right of each cell. I want it so that people can click on the left or right image in each cell, and something different happens based on the cell number. So if they click on the left image for cell in row 1, a function gets call with the row number they clicked on, and an indicator telling me they clicked on the left image and not the right image. How can I do that using objective-c?

• Manipulating values from database table with php

  - by charliecodex23

  I currently have 5 tables in MySQL database. Some of them share foreign keys and are interdependent of each other. I am displaying classes accordingly to their majors. Each class is taught during the fall, spring or all_year. In my database I have a table named semester which has an id, year, and semester fields. The semester field in particular is a tinyint that has three values 0, 1, 2. This signifies the fall, spring or all_year. When I display the query instead of having it show 0 or 1 or 2 can I have it show fall, spring etc? Extra: How can I add space to the end of each loop so the data doesn't look clustered? Key 0 Fall 1 Spring 2 All-year PHP <? try { $pdo = new PDO ("mysql:host=$hostname;dbname=$dbname","$username","$pw"); } catch (PDOException $e) { echo "Failed to get DB handle: " . $e->getMessage() .

• SQL SERVER – Working with FileTables in SQL Server 2012 – Part 2 – Methods to Insert Data Into Table

  - by pinaldave

  Read Part 1 Working with FileTables in SQL Server 2012 – Part 1 – Setting Up Environment In this second part of the series, we will see how we can insert the files into the FileTables. There are two methods to insert the data into FileTables: Method 1: Copy Paste data into the FileTables folder First, find the folder where FileTable will be storing the files. Go to Databases >> Newly Created Database (FileTableDB) >> Expand Tables. Here you will see a new folder which says “FileTables”. When expanded, it gives the name of the newly created “FileTableTb”. Right click on the newly created table, and click on “Explore FileTable Directory”. This will open up the folder where the FileTable data will be stored. When clicked on the option it will open up following folder in my local machine where the FileTable data will be stored. \\127.0.0.1\mssqlserver\FileTableDB\FileTableTb_Dir You can just copy your document just there. I copied few word document there and ran select statement to see the result. USE [FileTableDB] GO SELECT * FROM FileTableTb GO SELECT * returns all the rows. Here is SELECT statement which has only few columns selected from FileTable. SELECT [name] ,[file_type] ,CAST([file_stream] AS VARCHAR) FileContent ,[cached_file_size] ,[creation_time] ,[last_write_time] ,[last_access_time] FROM [dbo].[FileTableTb] GO I believe this is the simplest method to populate FileTable, because you just have to move the files to the specific table. Method 2: T-SQL Insert Statement There are always cases when you might want to programmatically insert the images into SQL Server File table. Here is a quick method which you can use to insert the data in the file table. I have inserted a very small text file using T-SQL, and later on, reading that using SELECT statement demonstrated in method 1 above. INSERT INTO [dbo].[FileTableTb] ([name],[file_stream]) SELECT 'NewFile.txt', * FROM OPENROWSET(BULK N'd:\NewFile.txt', SINGLE_BLOB) AS FileData GO The above T-SQL statement will copy the NewFile.txt to new location. When you run SELECT statement, it will retrieve the file and list in the resultset. Additionally, it returns the content in the SELECT statement as well. I think it is a pretty interesting way to insert the data into the FileTable. SELECT [name] ,[file_type] ,CAST([file_stream] AS VARCHAR) FileContent ,[cached_file_size] ,[creation_time] ,[last_write_time] ,[last_access_time] FROM [dbo].[FileTableTb] GO There are more to FileTable and we will see those in my future blog posts.

• What's the best way to cache a growing database table for html generation?

  - by McLeopold

  I've got a database table which will grow in size by about 5000 rows a hour. For a key that I would be querying by, the query will grow in size by about 1 row every hour. I would like a web page to show the latest rows for a key, 50 at a time (this is configurable). I would like to try and implement memcache to keep database activity low for reads. If I run a query and create a cache result for each page of 50 results, that would work until a new entry is added. At that time, the page of latest results gets new result and the oldest results drops off. This cascades down the list of cached pages causing me to update every cache result. It seems like a poor design. I could build the cache pages backwards, then for each page requested I should get the latest 2 pages and truncate to the proper length of 50. I'm not sure if this is good or bad? Ideally, the mechanism I use to insert a new row would also know how to invalidate the proper cache results. Has someone already solved this problem in a widely acceptable way? What's the best method of doing this? EDIT: If my understanding of the MYSQL query cache is correct, it has table level granularity in invalidation. Given the fact that I have about 5000 updates before a query on a key should need to be invalidated, it seems that the database query cache would not be used. MS SQL caches execution plans and frequently accessed data pages, so it may do better in this scenario. My query is not against a single table with TOP N. One version has joins to several tables and another has sub-selects. Also, since I want to cache the html generated table, I'm wondering if a cache at the web server level would be appropriate? Is there really no benefit to any type of caching? Is the best advice really to just allow a website site query to go through all the layers and hit the database every request?

• Get mutually and non mutually existening Fields in same table in Two columns

  - by ranabra

  This is a question similar to another question I posted here but is a little different. I am trying to get a list of all instances of mutual and non-mutual existing Users. What I mean is that the returned result from the query will return a list of users along with their co-worker. It is similar to the question here, but the difference is that non mutual users will be returned too and with out the "duplicity" mutually existing users return in the list (See image below in-order simplify it all). I took the original answer from Thomas (Thanx again Thomas) Select D1.u_username, U1.Permission, U1.Grade, D1.f_username, U2.Permission, U2.Gradefrom tblDynamicUserList As D1    Join tblDynamicUserList As D2        On D2.u_username = D1.f_username            And D2.f_username = D1.u_username    Join tblUsers As U1        On U1.u_username = D1.u_username    Join tblUsers As U2        On U2.u_username = D2.u_username and after some several trials I commented out 2 lines (Below). The returned result are exactly as described in the beginning of this question, but with the "duplicity" returned by mutually existing users in the table. How can I eliminate this duplicity? Select D1.u_username, U1.Permission, U1.Grade, D1.f_username, U2.Permission, U2.Gradefrom tblDynamicUserList As D1    Join tblDynamicUserList As D2        On D2.u_username = D1.f_username            /* And D2.f_username = D1.u_username */    Join tblUsers As U1        On U1.u_username = D1.u_username    Join tblUsers As U2        On U2.u_username = D2.u_username /* WHERE D1.U_userName < D1.f_username */ *Screenshot that hopefully helps explain it all. Database is SQL 2005. Many thanx in advance

• Resizing Images In a Table Using JavaScript

  - by Abluescarab

  Hey, all. I apologize beforehand if none of this makes sense, or if I sound incompetent... I've been making webpages for a while, but don't know any JavaScript. I am trying to make a webpage for a friend, and he requested if I could write some code to resize the images in the page based on the user's screen resolution. I did some research on this question, and it's kind of similar to this, this, and this. Unfortunately, those articles didn't answer my question entirely because none of the methods described worked. Right now, I have a three-column webpage with 10 images in a table in the left sidebar, and when I use percentages for their sizes, they don't resize right between monitors. As such, I'm trying to write a JavaScript function that changes their sizes after detecting the screen resolution. The code is stripped from my post if I put it all, so I'll just say that each image links to a website and uses a separate image to change color when you hover over it. Would I have to address both images to change their sizes correctly? I use a JavaScript function to switch between them. Anyway, I tried both methods in this article and neither worked for me. If it helps, I'm using Google Chrome, but I'm trying to make this page as cross-browser as possible. Here's the code I have so far in my JavaScript function: function resizeImages() { var w = window.width; var h = window.height; var yuk = document.getElementById('yuk').style; var wb = document.getElementById('wb').style; var tf = document.getElementById('tf').style; var lh = document.getElementById('lh').style; var ko = document.getElementById('ko').style; var gz = document.getElementById('gz').style; var fb = document.getElementById('fb').style; var eg = document.getElementById('eg').style; var dl = document.getElementById('dl').style; var da = document.getElementById('da').style; if (w = "800" && h = "600") { } else if (w = "1024" && h = "768") { } else if (w = "1152" && h = "864") { } else if (w = "1280" && h = "720") { } else if (w = "1280" && h = "768") { } else if (w = "1280" && h = "800") { } else if (w = "1280" && h = "960") { } else if (w = "1280" && h = "1024") { } } Yeah, I don't have much in it because I don't know if I'm doing it right yet. Is this a way I can detect the "width" and "height" properties of a window? The "yuk", "wb", etcetera are the images I'm trying to change the size of. To sum it up: I want to resize images based on screen resolution using JavaScript, but my research attempts have been... futile. I'm sorry if that was long-winded, but thanks ahead of time!

• iphone Dev - activity indicator with NSThread not working on Nav controller table view

  - by Frames84

  I really can't get this to work, basically when my JSON feeds loads I want the indicator to show, then hide when it's stopped. It loads top level menu items 1st "Publishing, Broadcasting, Marketing Services", then when Broadcasting is selected it loads a feed using the JSON framework hosted on Google. Round this load I call startIndicator and stopIndicator using the NSThread. Have I missed something? @implementation GeneralNewsTableViewController @synthesize dataList; @synthesize generalNewsDetailViewController; @synthesize atLevel; -(void) startIndicator { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc ] init ];

• JSF 2.0: java based custom component + html table + facelets = data model not updated

  - by mikic

  Hi, I'm having problems getting the data model of a HtmlDataTable to be correctly updated by JSF 2.0 and Facelets. I have created a custom Java-based component that extends HtmlDataTable and dynamically adds columns in the encodeBegin method. @Override public void encodeBegin(FacesContext context) throws IOException { if (this.findComponent("c0") == null) { for (int i = 0; i < 3; i++) { HtmlColumn myNewCol = new HtmlColumn(); myNewCol.setId("c" + i); HtmlInputText myNewText = new HtmlInputText(); myNewText.setId("t" + i); myNewText.setValue("#{row[" + i + "]}"); myNewCol.getChildren().add(myNewText); this.getChildren().add(myNewCol); } } super.encodeBegin(context); } My test page contains the following <h:form id="fromtb"> <test:MatrixTest id="tb" var="row" value="#{MyManagedBean.model}"> </test:MatrixTest> <h:commandButton id="btn" value="Set" action="#{MyManagedBean.mergeInput}"/> </h:form> <h:outputText id="mergedInput" value="#{MyManagedBean.mergedInput}"/> My managed bean class contains the following @ManagedBean(name="MyManagedBean") @SessionScoped public class MyManagedBean { private List model = null; private String mergedInput = null; public MyManagedBean() { model = new ArrayList(); List myFirst = new ArrayList(); myFirst.add(""); myFirst.add(""); myFirst.add(""); model.add(myFirst); List mySecond = new ArrayList(); mySecond.add(""); mySecond.add(""); mySecond.add(""); model.add(mySecond); } public String mergeInput() { StringBuffer myMergedInput = new StringBuffer(); for (Object object : model) { myMergedInput.append(object); } setMergedInput(myMergedInput.toString()); return null; } public List getModel() { return model; } public void setModel(List model) { this.model = model; } public String getMergedInput() { return mergedInput; } public void setMergedInput(String mergedInput) { this.mergedInput = mergedInput; } When invoked, the page is correctly rendered with a table made of 3 columns (added at runtime) and 2 rows (as my data model has 2 rows). However when the user enter some data in the input fields and then click the submit button, the model is not correctly updated and therefore the mergeInput() method creates a sequence of empty strings which is rendered on the same page. I have added some logging to the decode() method of my custom component and I can see that the parameters entered by the user are being posted back with the request, however these parameters are not used to update the data model. If I update the encodeBegin() method of my custom component as follow @Override public void encodeBegin(FacesContext context) throws IOException { super.encodeBegin(context); } and I update the test page as follow <test:MatrixTest id="tb" var="row" value="#{MyManagedBean.model}"> <h:column id="c0"><h:inputText id="t0" value="#{row[0]}"/></h:column> <h:column id="c1"><h:inputText id="t1" value="#{row[1]}"/></h:column> <h:column id="c2"><h:inputText id="t2" value="#{row[2]}"/></h:column> </test:MatrixTest> the page is correctly rendered and this time when the user enters data and submits the form, the underlying data model is correctly updated and the mergeInput() method creates a sequence of strings with the user data. Why does the test case with columns declared in the facelet page works correctly (ie the data model is correctly updated by JSF) where the same does not happen when the columns are created at runtime using the encodeBegin() method? Is there any method I need to invoke or interface I need to extend in order to ensure the data model is correctly updated? I am using this test case to address the issue that is appearing in a much more complex component, therefore I can't achieve the same functionality using a facelet composite component. Please note that this has been done using NetBeans 6.8, JRE 1.6.0u18, GlassFish 3.0. Thanks for your help.

• How does one check if a table exists in an Android SQLite database?

  - by camperdave

  I have an android app that needs to check if there's already a record in the database, and if not, process some things and eventually insert it, and simply read the data from the database if the data does exist. I'm using a subclass of SQLiteOpenHelper to create and get a rewritable instance of SQLiteDatabase, which I thought automatically took care of creating the table if it didn't already exist (since the code to do that is in the onCreate(...) method). However, when the table does NOT yet exist, and the first method ran upon the SQLiteDatabase object I have is a call to query(...), my logcat shows an error of "I/Database(26434): sqlite returned: error code = 1, msg = no such table: appdata", and sure enough, the appdata table isn't being created. Any ideas on why? I'm looking for either a method to test if the table exists (because if it doesn't, the data's certainly not in it, and I don't need to read it until I write to it, which seems to create the table properly), or a way to make sure that it gets created, and is just empty, in time for that first call to query(...)

• What stage of normalization is this? (moving repeating data into separate table)

  - by Sergio

  Hi There, I have noticed that when designing a database I tend to shift any repeating sets of data into a separate table. For example, say I had a table of people, with each person living in a state. I would then move these repeating states into a separate table and reference them with foreign keys. However, what if I was not storing any more data about states. I would then have a table with StateID and State in. Is this action correct? State is dependant on the primary key of the users table, so does shifting it into its own table help with anything? Thanks,

• CakePHP. How can i make a model test in a table with another primary key?

  - by Marcelo

  I have this table CREATE TABLE myexamples.problems ( id INT, name VARCHAR(45) NULL , pk_id INT AUTO_INCREMENT PRIMARY KEY ); But when I try test a model in cakephp, it fails because the table has two autoincrement attributes. The following query CREATE TABLE `test_suite_problems` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(45) DEFAULT NULL, `pk_id` int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`pk_id`) ) DEFAULT CHARSET=latin1, COLLATE=latin1_swedish_ci, ENGINE=InnoDB; raise this error: "1075: Incorrect table definition; there can be only one auto column and it must be defined as a key" I have in the model class <?php class Problem extends AppModel { var $name = 'Problem'; var $displayField = 'name'; var $primaryKey='problems'; } ?> But I don't know how to make the field ID not having an autoincrement attribute, and I can't change the table structure.

• How to return table name from stored procedure in dataset.

  - by Shantanu Gupta

  I used a dataset to store 15 tables that I need at the time of loading. When i filled all the tables using stored procedure it returns me all the table but name of the table doesn't comes as that of actual table name in a database. It takes all the table with table name as Table1, Table2, Table3... I want them to be with the name as they actually are in table. SELECT PK_GUEST_TYPE, [DESCRIPTION] FROM L_GUEST_TYPE SELECT PK_AGE_GROUP_ID, AGE_GROUP FROM L_AGE_GROUP SELECT PK_COMPANY_ID, COMPANY_NAME FROM M_COMPANY SELECT PK_COUNTRY_ID, COUNTRY FROM L_COUNTRY SELECT PK_EYE_COLOR_ID, [DESCRIPTION] FROM L_EYE_COLOR SELECT PK_GENDER_ID, [DESCRIPTION] FROM L_GENDER SELECT PK_HAIR_COLOR_ID, [DESCRIPTION] FROM L_HAIR_COLOR SELECT PK_STATE_PROVONCE_ID, [DESCRIPTION] FROM L_STATE_PROVINCE SELECT PK_STATUS_ID, [DESCRIPTION] FROM L_STATUS SELECT PK_TITLE_ID, [DESCRIPTION] FROM L_TITLE SELECT PK_TOWER_ID, [DESCRIPTION] FROM M_TOWER SELECT PK_CITY_ID, [DESCRIPTION] FROM L_CITY SELECT PK_REGISTER_TYPE_ID, [DESCRIPTION] FROM L_REGISTER_TYPE Here is my frontend coding to fill dataset.

• How do you select form elements in JQuery based upon an html table?

  - by Swoop

  I am working on some ASP.NET web forms which involves some dynamic generation, and I need to add some onClick helpers on the client side. I have a basic outline of something working, except for one huge problem. There are multiple HTML tables, each generated by a different ASP.NET web control. Each table can contain overlapping field names, which is causing a problem with my JQuery click event handlers. The click event handler is linking to unintended form fields in addition to the intended form field. I have provided a simplified sample version of the code below. This code is trying to set the value of textbox box1 when a particular radiobutton is selected in the table with id=thing1. Obviously, the jquery code will be triggered for the form fields in both tables. The tables are dynamically added to the webpage based upon different conditions. It is possible that no tables will be loaded, only 1 table, or both tables might load. In the future, other tables could be added. Each table comes from a different .net web control. Other than renaming the form fields to make sure they are unique across all user controls, is there a way to have JQuery act only on the intended form fields? In other words, could the table ID be incorporated into the JQuery code in a manner that does not become a nightmare to maintain later? <script> $(document).ready(function() { $("[id$=radio1_0]").click(function() { $("[id$=box1]").attr("value", ""); }); $("[id$=radio1_1]").click(function() { $("[id$=box1]").attr("value", "N/A"); }); </script> <table id="thing1"> <tr><td> <radiobuttonlist id="radio1"/> <listitem>yes</listitem> <listitem>no</listitem> </td></tr> <tr><td> <textbox id="box1"/> </td></tr> </table> <table id="thing2"> <tr><td> <radiobuttonlist id="radio1"/> <listitem>yes</listitem> <listitem>no</listitem> </td></tr> <tr><td> <textbox id="box1"/> </tr></td> </table>

• Please help me to allow my `JTable` to search the text even the table is in editable mode on key-press

  - by Ashish Pancholi

  If user starts pressing keys using keyboards then JTable is supposed to be searched the matching text for him and if user double clicks on cell then Table should allow him to edit the text. And the issue is - Table is only searching text when the table is in non-editable mode and if Table is editable and user starts typing the text-using keyboard, cell is allowing him to edit the cell rather then search. Mr mKorbel has just solved my issue to allow edit only if double click on Table cell. Please help me to allow my JTable to search the text even the table is in editable mode on key-press.
