  • PostgreSQL triggers and passing parameters

    - by iandouglas
    This is a multi-part question. I have a table similar to this: CREATE TABLE sales_data ( Company character(50), Contract character(50), top_revenue_sum integer, top_revenue_sales integer, last_sale timestamp) ; I'd like to create a trigger for new inserts into this table, something like this: CREATE OR REPLACE FUNCTION add_contract() RETURNS VOID DECLARE myCompany character(50), myContract character(50), BEGIN myCompany = TG_ARGV[0]; myContract = TG_ARGV[1]; IF (TG_OP = 'INSERT') THEN EXECUTE 'CREATE TABLE salesdata_' || $myCompany || '_' || $myContract || ' ( sale_amount integer, updated TIMESTAMP not null, some_data varchar(32), country varchar(2) ) ;' EXECUTE 'CREATE TRIGGER update_sales_data BEFORE INSERT OR DELETE ON salesdata_' || $myCompany || '_' || $myContract || ' FOR EACH ROW EXECUTE update_sales_data( ' || $myCompany || ',' || $myContract || ', revenue);' ; END IF; END; $add_contract$ LANGUAGE plpgsql; CREATE TRIGGER add_contract AFTER INSERT ON sales_data FOR EACH ROW EXECUTE add_contract() ; Basically, every time I insert a new row into sales_data, I want to generate a new table where the name of the table will be defined as something like "salesdata_Company_Contract" So my first question is how can I pass the Company and Contract data to the trigger so it can be passed to the add_contract() stored procedure? From my stored procedure, you'll see that I also want to update the original sales_data table whenever new data is inserted into the salesdata_Company_Contract table. This trigger will do something like this: CREATE OR REPLACE FUNCTION update_sales_data() RETURNS trigger as $update_sales_data$ DECLARE myCompany character(50) NOT NULL, myContract character(50) NOT NULL, myRevenue integer NOT NULL BEGIN myCompany = TG_ARGV[0] ; myContract = TG_ARGV[1] ; myRevenue = TG_ARGV[2] ; IF (TG_OP = 'INSERT') THEN UPDATE sales_data SET top_revenue_sales = top_revenue_sales + 1, top_revenue_sum = top_revenue_sum + $myRevenue, updated = now() WHERE Company = $myCompany AND Contract = $myContract ; ELSIF (TG_OP = 'DELETE') THEN UPDATE sales_data SET top_revenue_sales = top_revenue_sales - 1, top_revenue_sum = top_revenue_sum - $myRevenue, updated = now() WHERE Company = $myCompany AND Contract = $myContract ; END IF; END; $update_sales_data$ LANGUAGE plpgsql; This will, of course, require that I pass several parameters around within these stored procedures and triggers, and I'm not sure (a) if this is even possible, or (b) practical, or (c) best practice and we should just put this logic into our other software instead of asking the database to do this work for us. To keep our table sizes down, as we'll have hundreds of thousands of transactions per day, we've decided to partition our data using the Company and Contract strings as part of the table names themselves so they're all very small in size; file IO for us is faster and we felt we'd get better performance. Thanks for any thoughts or direction. My thinking, now that I've written all of this out, is that maybe we need to write stored procedures where we pass our insert data as parameters, and call that from our other software, and have the stored procedure do the insert into "sales_data" then create the other table. Then, have a second stored procedure to insert new data into the salesdata_Company_Contract tables, where the table name is passed to the stored proc as a parameter, and again have that stored proc do the insert, then update the main sales_data table afterward. What approach would you take?

  • Deleting xml file using radio value

    - by ???? ???
    i using php to delete file, but i got table loop like this: <table border="0" width="100%" cellpadding="0" cellspacing="0" id="product-table"> <tr class="bg_tableheader"> <th class="table-header-check"><a id="toggle-all" ></a> </th> <th class="table-header-check"><a href="#"><font color="white">Username</font></a> </th> <th class="table-header-check"><a href="#"><font color="white">First Name</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Last Name</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Email</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Group</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Birthday</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Gender</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Age</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Country</font></a></th> </tr> <?php $files = glob('users/*.xml'); foreach($files as $file){ $xml = new SimpleXMLElement($file, 0, true); echo ' <tr> <td></td> <form action="" method="post"> <td class="alternate-row1"><input type="radio" name="file_name" value="'. basename($file, '.xml') .'" />'. basename($file, '.xml') .'</td> <td>'. $xml->name .'&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp</td> <td class="alternate-row1">'. $xml->lastname .'</td> <td>'. $xml->email .'</td> <td class="alternate-row1">'. $xml->level .'</td> <td>'. $xml->birthday .'</td> <td class="alternate-row1">'. $xml->gender .'</td> <td>'. $xml->age .'</td> <td class="alternate-row1">'. $xml->country .'</td> </tr>'; } ?> </table> </div> <?php if(isset($_POST['file_name'])){ unlink('users/'.$_POST['file_name']); } ?> <input type="submit" value="Delete" /> </form> so as you can see i got radio value set has basename (xml file name) but from some reason it not working, any idea why is that? Thanks in advance.

  • onCommand on button not firing inside gridView??

    - by sah302
    This is really driving me crazy. I've got a button inside a gridview to remove that item from the gridview (its datasource is a list). I've got the list being saved to session anytime a change is being made to it, and on page_load check if that session variable is empty, if not, then set that list to bind to the gridview. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'If Not Session("associatedFaculty") Is Nothing Then' ' Dim associatedFacultyArray As User() = DirectCast(Session("associatedFaculty"), User())' ' associatedFaculty = associatedFacultyArray.ToList()' 'End If' Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) Session("associatedFaculty") = associatedFaculty.ToArray() gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) Session.Add("associatedFaculty", associatedFaculty.ToArray()) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub Delete(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) End Sub End Class Markup: <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList> &nbsp;<asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" OnClientClick="incrementCounter();" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now here is the crazy part I am simply boggled by, if I uncomment the If Not Session... block of page_load, then deleteUser will never fire when btnUnassignUser is clicked. If I keep it commented out...it fires no problem, but then of course my list can never have more than one item since I am not loading the saved list from session into the gridview but just a fresh one. But the button click is being registered, because page_load is being stepped through again when I am viewing in debug mode, just deleteUser never fires. Why is this happening?? And how can I fix it??

  • Destroying a record via RJS TemplateError (Called ID for nil...)

    - by bgadoci
    I am trying to destroy a record in my table via RJS and having some trouble. I have successfully implemented this before so can't quite understand what is not working here. Here is the setup: I am trying to allow a user of my app to select an answer from another user as the 'winning' answer to their question. Much like StackOverflow does. I am calling this selected answer 'winner'. class Winner < ActiveRecord::Base belongs_to :site belongs_to :user belongs_to :question validates_uniqueness_of :user_id, :scope => [:question_id] end I'll spare you the reverse has_many associations but I believe they are correct (I am using has_many with the validation as I might want to allow for multiple later). Also, think of site like an answer to the question. My link calling the destroy action of the WinnersController is located in the /views/winners/_winner.html.erb and has the following code: <% div_for winner do %> Selected <br/> <%=link_to_remote "Destroy", :url => winner, :method => :delete %> <% end %> This partial is being called by another partial `/views/sites/_site.html.erb and is located in this code block: <% if site.winners.blank? %> <% remote_form_for [site, Winner.new] do |f| %> <%= f.hidden_field :question_id, :value => @question.id %> <%= f.hidden_field :winner, :value => "1" %> <%= submit_tag "Select This Answer" %> Make sure you unselect any previously selected answers. <% end %> <% else %> <div id="winner_<%= site.id %>" class="votes"> <%= render :partial => site.winners%> </div> <% end %> <div id="winner_<%= site.id %>" class="votes"> </div> And the /views/sites/_site.html.erb partial is being called in the /views/questions/show.html.erb file. My WinnersController#destroy action is the following: def destroy @winner = Winner.find(params[:id]) @winner.destroy respond_to do |format| format.html { redirect_to Question.find(params[:post_id]) } format.js end end And my /views/winners/destroy.js.rjs code is the following: page[dom_id(@winner)].visual_effect :fade I am getting the following error and not really sure where I am going wrong: Processing WinnersController#destroy (for 127.0.0.1 at 2010-05-30 16:05:48) [DELETE] Parameters: {"authenticity_token"=>"nn1Wwr2PZiS2jLgCZQDLidkntwbGzayEoHWwR087AfE=", "id"=>"24", "_"=>""} Rendering winners/destroy ActionView::TemplateError (Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id) on line #1 of app/views/winners/destroy.js.rjs: 1: page[dom_id(@winner)].visual_effect :fade app/views/winners/destroy.js.rjs:1:in `_run_rjs_app47views47winners47destroy46js46rjs' app/views/winners/destroy.js.rjs:1:in `_run_rjs_app47views47winners47destroy46js46rjs' Rendered rescues/_trace (137.1ms) Rendered rescues/_request_and_response (0.3ms) Rendering rescues/layout (internal_server_error)

  • Fastest way to read data from a lot of ASCII files

    - by Alsenes
    Hi guys, for a college exercise that I've already submitted I needed to read a .txt file wich contained a lot of names of images(1 in each line). Then I needed to open each image as an ascii file, and read their data(images where in ppm format), and do a series of things with them. The things is, I noticed my program was taking 70% of the time in the reading the data from the file part, instead of in the other calculations that I was doing (finding number of repetitions of each pixel with a hash table, finding diferents pixels beetween 2 images etc..), which I found quite odd to say the least. This is how the ppm format looks like: P3 //This value can be ignored when reading the file, because all image will be correctly formatted 4 4 255 //This value can be also ignored, will be always 255. 0 0 0 0 0 0 0 0 0 15 0 15 0 0 0 0 15 7 0 0 0 0 0 0 0 0 0 0 0 0 0 15 7 0 0 0 15 0 15 0 0 0 0 0 0 0 0 0 This is how I was reading the data from the files: ifstream fdatos; fdatos.open(argv[1]); //Open file with the name of all the images const int size = 128; char file[size]; //Where I'll get the image name Image *img; while (fdatos >> file) { //While there's still images anmes left, continue ifstream fimagen; fimagen.open(file); //Open image file img = new Image(fimagen); //Create new image object with it's data file ……… //Rest of the calculations whith that image ……… delete img; //Delete image object after done fimagen.close(); //Close image file after done } fdatos.close(); And inside the image object read the data like this: const int tallafirma = 100; char firma[tallafirma]; fich_in >> std::setw(100) >> firma; // Read the P3 part, can be ignored int maxvalue, numpixels; fich_in >> height >> width >> maxvalue; // Read the next three values numpixels = height*width; datos = new Pixel[numpixels]; int r,g,b; //Don't need to be ints, max value is 256, so an unsigned char would be ok. for (int i=0; i<numpixels; i++) { fich_in >> r >> g >> b; datos[i] = Pixel( r, g ,b); } //This last part is the slow one, //I thing I should be able to read all this data in one single read //to buffer or something which would be stored in an array of unsigned chars, //and then I'd only need to to do: //buffer[0] -> //Pixel 1 - Red data //buffer[1] -> //Pixel 1 - Green data //buffer[2] -> //Pixel 1 - Blue data So, any Ideas? I think I can improve it quite a bit reading all to an array in one single call, I just don't know how that is done. Also, is it posible to know how many images will be in the "index file"? Is it posiible to know the number of lines a file has?(because there's one file name per line..) Thanks!!

  • listview and datalist not updating,inserting

    - by raging_boner
    Data entered in textboxes is not getting updated in database. In debug mode I see that text1 and text2 in ItemUpdating event contain the same values as they had before calling ItemUpdating. Here's my listview control: <asp:ListView ID="ListView1" runat="server" onitemediting="ListView1_ItemEditing" onitemupdating="ListView1_ItemUpdating" oniteminserting="ListView1_ItemInserting"> //LayoutTemplate removed <ItemTemplate> <asp:Label ID="Label2" runat="server" Text='<%#Eval("id")%>'></asp:Label> <asp:Label ID="Label3" runat="server" Text='<%#Eval("text1")%>'></asp:Label> <asp:LinkButton ID="LinkButton2" CommandName="Edit" runat="server">Edit</asp:LinkButton> <asp:LinkButton ID="LinkButton4" CommandName="Delete" runat="server">Delete</asp:LinkButton> </ItemTemplate> <EditItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%#Eval("id")%>'></asp:Label> <asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("text1")%>' TextMode="MultiLine" /> <asp:TextBox ID="TextBox2" runat="server" Text='<%#Eval("text2")%>' Height="100" TextMode="MultiLine" /> <asp:LinkButton ID="LinkButton1" CommandName="Update" CommandArgument='<%# Eval("id")%>' runat="server">Update</asp:LinkButton> <asp:LinkButton ID="LinkButton5" CommandName="Cancel" runat="server">Cancel</asp:LinkButton> </EditItemTemplate> <InsertItemTemplate> <asp:TextBox ID="TextBox3" runat="server" TextMode="MultiLine" Height="100"></asp:TextBox> <asp:TextBox ID="TextBox4" runat="server" Height="100" TextMode="MultiLine"></asp:TextBox> <asp:LinkButton ID="LinkButton3" runat="server">Insert</asp:LinkButton> </InsertItemTemplate> </asp:ListView> Codebehind file: protected void ListView1_ItemEditing(object sender, ListViewEditEventArgs e) { ListView1.EditIndex = e.NewEditIndex; BindList(); } protected void ListView1_ItemUpdating(object sender, ListViewUpdateEventArgs e) { ListViewItem myItem = ListView1.Items[ListView1.EditIndex]; Label id = (Label)myItem.FindControl("Label1"); int dbid = int.Parse(id.Text); TextBox text1 = (TextBox)myItem.FindControl("Textbox1"); TextBox text2 = (TextBox)myItem.FindControl("Textbox2"); //tried to work withNewValues below, but they don't work, "null reference" error is being thrown //text1.Text = e.NewValues["text1"].ToString(); //text2.Text = e.NewValues["text2"].ToString(); //odbc connection routine removed. //i know that there should be odbc parameteres: comm = new OdbcCommand("UPDATE table SET text1 = '" + text1.Text + "', text2 = '" + text2.Text + "' WHERE id = '" + dbid + "'", connection); comm.ExecuteNonQuery(); conn.Close(); ListView1.EditIndex = -1; //here I databind ListView1 } What's wrong with updating of text1.Text, text2.Text in ItemUpdating event? Should I use e.NewValues property? If so, how to use it? Thanks in advance for any help.

  • mysql_close doesn't kill locked sql requests

    - by Nikita
    I use mysqld Ver 5.1.37-2-log for debian-linux-gnu I perform mysql calls from c++ code with functions mysql_query. The problem occurs when mysql_query execute procedure, procedure locked on locked table, so mysql_query hangs. If send kill signal to application then we can see lock until table is locked. Create the following SQL table and procedure CREATE TABLE IF NOT EXISTS `tabletolock` ( `id` INT NOT NULL AUTO_INCREMENT, PRIMARY KEY (`id`) )ENGINE = InnoDB; DELIMITER $$ DROP PROCEDURE IF EXISTS `LOCK_PROCEDURE` $$ CREATE PROCEDURE `LOCK_PROCEDURE`() BEGIN SELECT id INTO @id FROM tabletolock; END $$ DELOMITER; There are sql commands to reproduce the problem: 1. in one terminal execute lock tables tabletolock write; 2. in another terminal execute call LOCK_PROCEDURE(); 3. In first terminal exeute show processlist and see | 2492 | root | localhost | syn_db | Query | 12 | Locked | SELECT id INTO @id FROM tabletolock | Then perfrom Ctrl-C in second terminal to interrupt our procudere and see processlist again. It is not changed, we already see locked select request and can teminate it by unlock tables or kill commands. Problem described is occured with mysql command line client. Also such problem exists when we use functions mysql_query and mysql_close. Example of c code: #include <iostream> #include <mysql/mysql.h> #include <mysql/errmsg.h> #include <signal.h> // g++ -Wall -g -fPIC -lmysqlclient dbtest.cpp using namespace std; MYSQL * connection = NULL; void closeconnection() { if(connection != NULL) { cout << "close connection !\n"; mysql_close(connection); mysql_thread_end(); delete connection; mysql_library_end(); } } void sigkill(int s) { closeconnection(); signal(SIGINT, NULL); raise(s); } int main(int argc, char ** argv) { signal(SIGINT, sigkill); connection = new MYSQL; mysql_init(connection); mysql_options(connection, MYSQL_READ_DEFAULT_GROUP, "nnfc"); if (!mysql_real_connect(connection, "127.0.0.1", "user", "password", "db", 3306, NULL, CLIENT_MULTI_RESULTS)) { delete connection; cout << "cannot connect\n"; return -1; } cout << "before procedure call\n"; mysql_query(connection, "CALL LOCK_PROCEDURE();"); cout << "after procedure call\n"; closeconnection(); return 0; } Compile it, and perform the folloing actions: 1. in first terminal local tables tabletolock write; 2. run program ./a.out 3. interrupt program Ctrl-C. on the screen we see that closeconnection function is called, so connection is closed. 4. in first terminal execute show processlist and see that procedure was not intrrupted. My question is how to terminate such locked calls from c code? Thank you in advance!

It shows unpredictable behaviour and stops listening for some folders and runs perfectly for the others. I hope you guys help me.I tried many ways but it doesnt work perfectly.Am I doing something wrong??? or there we have some other way to do this....... Please help me........I have to get this done withing few days...... Any help is appreciated!!!! Thanks in Advance Nemat

  • Hibernate: update on parent-child relationship causes duplicate children

    - by TimmyJ
    I have a parent child relationship in which the parent has a collection of children (a set to be specific). The child collection is setup with cascade="all-delete-orphan". When I initially save the parent element everything works as expected. However, when I update the parent and save again, all the children are re-saved. This behavior leads me to believe that the parent is losing its reference to the collection of children, and therefore when persisting all the children are re-saved. It seems the only way to fix this is to not use the setter method of this child collection, but unfortunately this setter is called implicitly in my application (Spring MVC is used to bind a multi-select form element to this collection, and the setter is called by spring on the form submission). Overwriting this setter to not lose the reference (ie, do a colleciton.clear() and collection.addAll(newCollection) rather than collection = newCollection) is apparently a hibernate no-no, as is pointed out here: https://forum.hibernate.org/viewtopic.php?t=956859 Does anyone know how to circumvent this problem? I've posted some of my code below. The parent hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="ReportCriteriaBean" table="masterPkReportCriteria"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <set name="treatmentArms" table="masterPkTreatmentArms" sort="org.fstrf.masterpk.domain.RxCodeComparator" lazy="false" cascade="all-delete-orphan" inverse="true"> <key column="runid"/> <one-to-many class="TreatmentArm"/> </set> </class> </hibernate-mapping> The parent object: public class ReportCriteriaBean{ private Integer id; private Set<TreatmentArm> treatmentArms; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public Set<TreatmentArm> getTreatmentArms() { return treatmentArms; } public void setTreatmentArms(Set<TreatmentArm> treatmentArms) { this.treatmentArms = treatmentArms; if(this.treatmentArms != null){ for(TreatmentArm treatmentArm : this.treatmentArms){ treatmentArm.setReportCriteriaBean(this); } } } The child hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="TreatmentArm" table="masterPkTreatmentArms"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <many-to-one name="reportCriteriaBean" class="ReportCriteriaBean" column="runId" not-null="true" /> <property name="rxCode" column="rxCode" not-null="true"/> </class> </hibernate-mapping> The child object: public class TreatmentArm { private Integer id; private ReportCriteriaBean reportCriteriaBean; private String rxCode; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public ReportCriteriaBean getReportCriteriaBean() { return reportCriteriaBean; } public void setReportCriteriaBean(ReportCriteriaBean reportCriteriaBean) { this.reportCriteriaBean = reportCriteriaBean; } public String getRxCode() { return rxCode; } public void setRxCode(String rxCode) { this.rxCode = rxCode; } }

  • Clearcase - selective merge.

    - by Keshav
    Hi, I have a peculiar Clearcase doubt. I cannot fully describe why I'm doing such a confusing architecture, but I need to do it (thanks to the mistake done by someone long back). Ok, here's a bit of detail: B1 is a contaminated branch where both my group's changes and another group's changes got mixed together so badly that there is no way of finding which code is whose). So the solution proposed is to create a new branch called B2 (at the same level as B1) and put all the unmodified code of the other group on it (The way to do that would be to merge B1 with B2 and then go about removing all changes from it till it becomes original). Then create a CR branch on B1 and keep only my group's newly added files or modified files on that branch. Finally create an integration branch out of B2 and merge the changes from CR branch of B1 to integration branch of B2. So here is what I did: (The use case is where I have dir D where file a, b and c are there. My group ended up modifying file a while b and c are not modified at all). There is a branch B1 on which there are files a, b and c. There is another branch B2. A merge is done from B1 to B2. Now B2 also has a, b and c. At this point both branch B1 and B2 are same. Now I delete file a from branch B2 (rmname). Now B2 has b and c only. I put a label to this branch called Label1. This makes the code with label Label1 as the unmodified code from other group. Now I create a sub branch called CR1 from B1 and delete all the files that are there in B2 branch (i.e b and c) such that it contains only the modified code from original code on it. In my case it is file a. At this point branch B2 with label Label1 has files b and c (those are unmodified code) and branch CR1 coming off B1 has only a (that is modified by us). Now I create another branch called integration branch that comes off B2 Label1. And then I do a merge of CR branch on to that expecting that it will have all three files a, b and c for me. All I'd need to do is to do a version tree view and see who modified what. But the problem I face is that since I had done a rmname of file a on branch B2 earlier to putting Label. The merge does not really take the file a from CR branch. How to I get around that problem. I want to selectively merge. Is it possible? sorry if it is a bad design. I'm not really conversant with Clear case and have limited options and time to clear some one else's mess.

  • Is there a potential for resource leak/double free here?

    - by nhed
    The following sample (not compiled so I won't vouch for syntax) pulls two resources from resource pools (not allocated with new), then "binds" them together with MyClass for the duration of a certain transaction. The transaction, implemented here by myFunc, attempts to protect against leakage of these resources by tracking their "ownership". The local resource pointers are cleared when its obvious that instantiation of MyClass was successful. The local catch, as well as the destructor ~MyClass return the resources to their pool (double-frees are protected by teh above mentioned clearing of the local pointers). Instantiation of MyClass can fail and result in an exception at two steps (1) actual memory allocation, or (2) at the constructor body itself. I do not have a problem with #1, but in the case of #2, if the exception is thrown AFTER m_resA & m_resB were set. Causing both the ~MyClass and the cleanup code of myFunc to assume responsibility for returning these resources to their pools. Is this a reasonable concern? Options I have considered, but didn't like: Smart pointers (like boost's shared_ptr). I didn't see how to apply to a resource pool (aside for wrapping in yet another instance). Allowing double-free to occur at this level but protecting at the resource pools. Trying to use the exception type - trying to deduce that if bad_alloc was caught that MyClass did not take ownership. This will require a try-catch in the constructor to make sure that any allocation failures in ABC() ...more code here... wont be confused with failures to allocate MyClass. Is there a clean, simple solution that I have overlooked? class SomeExtResourceA; class SomeExtResourceB; class MyClass { private: // These resources come out of a resource pool not allocated with "new" for each use by MyClass SomeResourceA* m_resA; SomeResourceB* m_resB; public: MyClass(SomeResourceA* resA, SomeResourceB* resB): m_resA(resA), m_resB(resB) { ABC(); // ... more code here, could throw exceptions } ~MyClass(){ if(m_resA){ m_resA->Release(); } if(m_resB){ m_resB->Release(); } } }; void myFunc(void) { SomeResourceA* resA = NULL; SomeResourceB* resB = NULL; MyClass* pMyInst = NULL; try { resA = g_pPoolA->Allocate(); resB = g_pPoolB->Allocate(); pMyInst = new MyClass(resA,resB); resA=NULL; // ''ownership succesfully transfered to pMyInst resB=NULL; // ''ownership succesfully transfered to pMyInst // Do some work with pMyInst; ...; delete pMyInst; } catch (...) { // cleanup // need to check if resA, or resB were allocated prior // to construction of pMyInst. if(resA) resA->Release(); if(resB) resB->Release(); delete pMyInst; throw; // rethrow caught exception } }

  • Pass existing model into AJAX PartialViewResult

I'm guessing I somehow have to pass the model to the SHIPDEL Action first. I couldn't find an @Ajax.ActionLink overload that would allow this. public PartialViewResult SHIPDEL() { return PartialView("AJAX_Views/_ShipDel", this.ModelState); } In the _ShipDel Partial View I need to expose the CmpAdrsSh properties so the model validates in the POST Action. The model is empty at this point. How do I pass the existing vM model into the _ShipDel partial view? Thank you,

  • jquery live problem

    - by Kay
    Hi, I have a website which uses jquery and lots of mouseover/mouseout effect. So far I used the .bind() method of jquery but if you have 1000 event handlers, this is slowing down your browser a lot. So, I want to move to use .live or .delegate. One part of my portal site is a chat area. User can set chat messages which will then be displayed in a simple table. There is a feature that if you move the mouse over a chat message a trash can will appear allowing you to delete the message (if it is by you or you are a moderator). The trash bin is in the same table cell as the chat message. The problem: Using .bind() it worked like a charm. This is the old code: function CreateChatMessageContextMenu(ctrl, messageID, message, sender) { var a = document.createElement("a"); a.href = "javascript:RemoveChatMessage(" + messageID + ");" a.id = 'aDeleteChatMessage' + messageID; a.style.display = 'none'; var img = document.createElement("span"); img.className = "sprite-common messages-image sprite-common-btnDelete"; a.appendChild(img); ctrl.appendChild(a); $(ctrl) .bind('mouseover', function(event) { $('#aDeleteChatMessage' + messageID).show() }) .bind('mouseout', function(event) { $('#aDeleteChatMessage' + messageID).hide() }); return; } 'ctrl' is the reference to a table cell. Now, using .live() the trashbin also appears but it is flickering a lot and when I move the mouse over the trashbin, it is disappearing or inactive. I have the feeling that more events are thrown or something. It seems like the 'mouseout' is thrown when moving over the trashbin, but the thrashbin is inside the tablecell so mouseout should not be triggered. The new code is as follows. $(document).ready { $('.jDeleteableChatMessage').live('mouseover mouseout', function(event) { var linkID = '#aDelete' + event.target.id; if (event.type == 'mouseover') { $(linkID).show(); } else { $(linkID).hide(); } return false; }); } function CreateChatMessageContextMenu(ctrl, messageID, message, sender) { if (!UserIsModerator && (UserLogin != sender)) return; ctrl.id = 'ChatMessage' + messageID; var deleteString = 'Diese Chatnachricht löschen'; if (UserLang == '1') deleteString = 'Delete this chat message'; var a = document.createElement("a"); a.href = "javascript:RemoveChatMessage(" + messageID + ");" a.id = 'aDeleteChatMessage' + messageID; a.style.display = 'none'; var img = document.createElement("span"); img.className = "sprite-common messages-image sprite-common-btnDelete"; img.alt = deleteString; img.title = deleteString; a.appendChild(img); ctrl.appendChild(a); $(ctrl).addClass('jDeleteableChatMessage'); } I add a class to tell jQuery which chat cell have a trash bin and which don't. I also add an ID to the table cell which is later used to determine the associated trash bin. Yes, that's clumsy data passing to an event method. And, naturally, there is the document.ready function which initialises the .live() method. So, where is my mistake?

  • Delphi: EReadError with message ‘Property PageNr does Not Exist’.

    - by lyborko
    Hi, I get SOMETIMES error message: EReadError with message 'Property PageNr does Not exist', when I try to run my own project. I am really desperate, because I see simply nothing what is the cause. The devilish is that it comes up sometimes but often. It concerns of my own component TPage. Here is declaration TPage = class(TCustomControl) // private FPaperHeight, FPaperWidth:Integer; FPaperBrush:TBrush; FPaperSize:TPaperSize; FPaperOrientation:TPaperOrientation; FPDFDocument: TPDFDocument; FPageNr:integer; procedure PaintBasicLayout; procedure PaintInterior; procedure SetPapersize(Value: TPapersize); procedure SetPaperHeight(Value: Integer); procedure SetPaperWidth(Value: Integer); procedure SetPaperOrientation(value:TPaperOrientation); procedure SetPaperBrush(Value:TBrush); procedure SetPageNr(Value:Integer); protected procedure CreateParams(var Params:TCreateParams); override; procedure AdjustClientRect(var Rect: TRect); override; public constructor Create(AOwner: TComponent);override; destructor Destroy;override; // function GetChildOwner:TComponent; override; procedure DrawControl(X,Y :integer; Dx,Dy:Double; Ctrl:TControl;NewCanvas:TCanvas); // procedure GetChildren(Proc:TGetChildProc; Root:TComponent); override; procedure Loaded; override; procedure MouseDown(Button: TMouseButton; Shift: TShiftState; X, Y: Integer); override; procedure Paint; override; procedure PrintOnCanvas(X,Y:integer; rX,rY:Double; ACanvas:TCanvas); procedure PrintOnPDFCanvas(X,Y:integer); procedure PrintOnPrinterCanvas(X,Y:integer); procedure Resize; override; procedure SetPrintKind(APrintKind:TPrintKind; APrintGroupindex:Integer); published property PageNr:integer read FPageNr write SetPageNr; property PaperBrush: TBrush read FPaperBrush write SetPaperBrush; property PaperHeight: integer read FPaperHeight write SetPaperHeight; property PaperWidth: integer read FPaperWidth write SetPaperWidth; property PaperSize: TPaperSize read FPaperSize write SetPaperSize; property PaperOrientation:TPaperOrientation read FPaperOrientation write SetPaperOrientation; property PDFDocument:TPDFDocument read FPDFDocument write FPDFDocument; property TabOrder; end; I thoroughly read the similar topic depicted here: Delphi: EReadError with message 'Property Persistence does Not exist' But here it is my own source code. No third party. Interesting: when I delete PageNr property in my dfm file (unit1.dfm), then pops up : EReadError with message 'Property PaperHeight does Not exist'. when I delete PaperHeight then it will claim PaperWidth and so on...

Here's my listview control: <asp:ListView ID="ListView1" runat="server" onitemediting="ListView1_ItemEditing" onitemupdating="ListView1_ItemUpdating" oniteminserting="ListView1_ItemInserting"> //LayoutTemplate removed <ItemTemplate> <td align="center" valign="top"> <asp:Label ID="Label2" runat="server" Text='<%#Eval("id")%>'></asp:Label><br /> <asp:Label ID="Label3" runat="server" Text='<%#Eval("text1")%>'></asp:Label> </td> <td> <asp:LinkButton ID="LinkButton2" CommandName="Edit" runat="server">Edit</asp:LinkButton> <asp:LinkButton ID="LinkButton4" CommandName="Delete" runat="server">Delete</asp:LinkButton> </td> </ItemTemplate> <EditItemTemplate> <td align="center" valign="top"> <asp:Label ID="Label1" runat="server" Text='<%#Eval("id")%>'></asp:Label> <asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("text1")%>' TextMode="MultiLine" /> <asp:TextBox ID="TextBox2" runat="server" Text='<%#Eval("text2")%>' Height="100" TextMode="MultiLine" /> <asp:LinkButton ID="LinkButton1" CommandName="Update" CommandArgument='<%# Eval("id")%>' runat="server">Update</asp:LinkButton> <asp:LinkButton ID="LinkButton5" CommandName="Cancel" runat="server">Cancel</asp:LinkButton> </td> </EditItemTemplate> <InsertItemTemplate> <td align="center" valign="top"> <asp:TextBox ID="TextBox3" runat="server" TextMode="MultiLine" Height="100"></asp:TextBox> <asp:TextBox ID="TextBox4" runat="server" Height="100" TextMode="MultiLine"></asp:TextBox><br/> <asp:LinkButton ID="LinkButton3" runat="server">Insert</asp:LinkButton> </td> </InsertItemTemplate> </asp:ListView> Codebehind file: protected void ListView1_ItemEditing(object sender, ListViewEditEventArgs e) { ListView1.EditIndex = e.NewEditIndex; BindList(); } protected void ListView1_ItemUpdating(object sender, ListViewUpdateEventArgs e) { ListViewItem myItem = ListView1.Items[ListView1.EditIndex]; Label id = (Label)myItem.FindControl("Label1"); int dbid = int.Parse(id.Text); TextBox text1 = (TextBox)myItem.FindControl("Textbox1"); TextBox text2 = (TextBox)myItem.FindControl("Textbox2"); //tried to work withNewValues below, but they don't work, "null reference" error is being thrown //text1.Text = e.NewValues["text1"].ToString(); //text2.Text = e.NewValues["text2"].ToString(); //odbc connection routine removed. //i know that there should be odbc parameteres: comm = new OdbcCommand("UPDATE table SET text1 = '" + text1.Text + "', text2 = '" + text2.Text + "' WHERE id = '" + dbid + "'", connection); comm.ExecuteNonQuery(); conn.Close(); ListView1.EditIndex = -1; //here I databind ListView1 } What's wrong with updating of text1.Text, text2.Text in ItemUpdating event? Should I use e.NewValues property? If so, how to use it? Thanks in advance for any help.

  • allocating extra memory for a container class.

    - by sil3nt
    Hey there, I'm writing a template container class and for the past few hours have been trying to allocate new memory for extra data that comes into the container (...hit a brick wall..:| ) template <typename T> void Container<T>::insert(T item, int index){ if ( index < 0){ cout<<"Invalid location to insert " << index << endl; return; } if (index < sizeC){ //copying original array so that when an item is //placed in the middleeverything else is shifted forward T *arryCpy = 0; int tmpSize = 0; tmpSize = size(); arryCpy = new T[tmpSize]; int i = 0, j = 0; for ( i = 0; i < tmpSize; i++){ for ( j = index; j < tmpSize; j++){ arryCpy[i] = elements[j]; } } //overwriting and placing item and location index elements[index] = item; //copying back everything else after the location at index int k = 0, l = 0; for ( k =(index+1), l=0; k < sizeC || l < (sizeC-index); k++,l++){ elements[k] = arryCpy[l]; } delete[] arryCpy; arryCpy = 0; } //seeing if the location is more than the current capacity //and hence allocating more memory if (index+1 > capacityC){ int new_capacity = 0; int current_size = size(); new_capacity = ((index+1)-capacityC)+capacityC; //variable for new capacity T *tmparry2 = 0; tmparry2 = new T[new_capacity]; int n = 0; for (n = 0; n < current_size;n++){ tmparry2[n] = elements[n]; } delete[] elements; elements = 0; //copying back what we had before elements = new T[new_capacity]; int m = 0; for (m = 0; m < current_size; m++){ elements[m] = tmparry2[m]; } //placing item elements[index] = item; } else{ elements[index] = item; } //increasing the current count sizeC++; my testing condition is Container cnt4(3); and as soon as i hit the fourth element (when I use for egsomething.insert("random",3);) it crashes and the above doesnt work. where have I gone wrong?

  • How to copy bytes from buffer into the managed struct?

    - by Chupo_cro
    I have a problem with getting the code to work in a managed environment (VS2008 C++/CLI Win Forms App). The problem is I cannot declare the unmanaged struct (is that even possible?) inside the managed code, so I've declared a managed struct but now I have a problem how to copy bytes from buffer into that struct. Here is the pure C++ code that obviously works as expected: typedef struct GPS_point { float point_unknown_1; float latitude; float longitude; float altitude; // x10000 float time; int point_unknown_2; int speed; // x100 int manually_logged_point; // flag (1 --> point logged manually) } track_point; int offset = 0; int filesize = 256; // simulates filesize int point_num = 10; // simulates number of records int main () { char *buffer_dyn = new char[filesize]; // allocate RAM // here, the file would have been read into the buffer buffer_dyn[0xa8] = 0x1e; // simulates the speed data (1e 00 00 00) buffer_dyn[0xa9] = 0x00; buffer_dyn[0xaa] = 0x00; buffer_dyn[0xab] = 0x00; offset = 0x90; // if the data with this offset is transfered trom buffer // to struct, int speed is alligned with the buffer at the // offset of 0xa8 track_point *points = new track_point[point_num]; points[0].speed = 0xff; // (debug) it should change into 0x1e memcpy(&points[0],buffer_dyn+offset,32); cout << "offset: " << offset << "\r\n"; //cout << "speed: " << points[0].speed << "\r\n"; printf ("speed : 0x%x\r\n",points[0].speed); printf("byte at offset 0xa8: 0x%x\r\n",(unsigned char)buffer_dyn[0xa8]); // should be 0x1e delete[] buffer_dyn; // release RAM delete[] points; /* What I need is to rewrite the lines 29 and 31 to work in the managed code (VS2008 Win Forms C++/CLI) What should I have after: array<track_point^>^ points = gcnew array<track_point^>(point_num); so I can copy 32 bytes from buffer_dyn to the managed struct declared as typedef ref struct GPS_point { float point_unknown_1; float latitude; float longitude; float altitude; // x10000 float time; int point_unknown_2; int speed; // x100 int manually_logged_point; // flag (1 --> point logged manually) } track_point; */ return 0; } Here is the paste to codepad.org so it can be seen the code is OK. What I need is to rewrite these two lines: track_point *points = new track_point[point_num]; memcpy(&points[0],buffer_dyn+offset,32); to something that will work in a managed application. I wrote: array<track_point^>^ points = gcnew array<track_point^>(point_num); and now trying to reproduce the described copying of the data from buffer over the struct, but haven't any idea how it should be done. Alternatively, if there is a way to use an unmanaged struct in the same way shown in my code, then I would like to avoid working with managed struct.

  • MCV PHP Am I doing the Model right? [closed]

    - by Kosmo
    I'm trying to create a basic website using MVC in PHP to learn MVC. Its eventually going to be some sort of social networking website but right now I am trying to create a object that can create, delete, update members. What I've done so far for the Model is in the code below, I figure my Controller will take user input and build the array of data that are then passed to this Model. Am I designing this correctly? Should the Controller be the one building the Arrays? <?php class Connection { private $server; private $database; private $user; private $password; private $conn; function __construct($server, $database, $user, $password) { $this->server = $server; $this->database = $database; $this->user = $user; $this->password = $password; } function connect() { $this->conn = mysql_connect($this->server, $this->user, $this->password) or die(mysql_error()); if (!(mysql_select_db($this->database))) { throw new Exception("Could not connect to database!"); } } function deleteMember($memberId) { $queryString = "DELETE FROM Members WHERE MemberId=" . $memberId . ';'; if (!mysql_query($queryString)) { throw new Exception("Failed Deleting Member!"); } } function insertMember($columns) { $queryString = 'INSERT INTO Members'; $keys = '('; $values = '('; $count = 0; foreach($columns as $key => $value) { $keys .= $key; $values .= $value; if (!(++$count == count($columns))) { $keys .= ','; $values .= ','; } } $queryString .= $keys .

  • Reading input from a text file, omits the first and adds a nonsense value to the end?

    - by Greenhouse Gases
    Hi there When I input locations from a txt file I am getting a peculiar error where it seems to miss off the first entry, yet add a garbage entry to the end of the link list (it is designed to take the name, latitude and longitude for each location you will notice). I imagine this to be an issue with where it starts collecting the inputs and where it stops but I cant find the error!! It reads the first line correctly but then skips to the next before adding it because during testing for the bug it had no record of the first location Lisbon though whilst stepping into the method call it was reading it. Very bizarre but hopefully someone knows the issue. Here is firstly my header file: #include <string> struct locationNode { char nodeCityName [35]; double nodeLati; double nodeLongi; locationNode* Next; void CorrectCase() // Correct upper and lower case letters of input { int MAX_SIZE = 35; int firstLetVal = this->nodeCityName[0], letVal; int n = 1; // variable for name index from second letter onwards if((this->nodeCityName[0] >90) && (this->nodeCityName[0] < 123)) // First letter is lower case { firstLetVal = firstLetVal - 32; // Capitalise first letter this->nodeCityName[0] = firstLetVal; } while(n <= MAX_SIZE - 1) { if((this->nodeCityName[n] >= 65) && (this->nodeCityName[n] <= 90)) { letVal = this->nodeCityName[n] + 32; this->nodeCityName[n] = letVal; } n++; } //cityNameInput = this->nodeCityName; } }; class Locations { private: int size; public: Locations(){ }; // constructor for the class locationNode* Head; //int Add(locationNode* Item); }; And here is the file containing main: // U08221.cpp : main project file. #include "stdafx.h" #include "Locations.h" #include <iostream> #include <string> #include <fstream> using namespace std; int n = 0,x, locationCount = 0, MAX_SIZE = 35; string cityNameInput; char targetCity[35]; bool acceptedInput = false, userInputReq = true, match = false, nodeExists = false;// note: addLocation(), set to true to enable user input as opposed to txt file locationNode *start_ptr = NULL; // pointer to first entry in the list locationNode *temp, *temp2; // Part is a pointer to a new locationNode we can assign changing value followed by a call to Add locationNode *seek, *bridge; void setElementsNull(char cityParam[]) { int y=0, count =0; while(cityParam[y] != NULL) { y++; } while(y < MAX_SIZE) { cityParam[y] = NULL; y++; } } void addLocation() { temp = new locationNode; // declare the space for a pointer item and assign a temporary pointer to it if(!userInputReq) // bool that determines whether user input is required in adding the node to the list { cout << endl << "Enter the name of the location: "; cin >> temp->nodeCityName; temp->CorrectCase(); setElementsNull(temp->nodeCityName); cout << endl << "Please enter the latitude value for this location: "; cin >> temp->nodeLati; cout << endl << "Please enter the longitude value for this location: "; cin >> temp->nodeLongi; cout << endl; } temp->Next = NULL; //set to NULL as when one is added it is currently the last in the list and so can not point to the next if(start_ptr == NULL){ // if list is currently empty, start_ptr will point to this node start_ptr = temp; } else { temp2 = start_ptr; // We know this is not NULL - list not empty! while (temp2->Next != NULL) { temp2 = temp2->Next; // Move to next link in chain until reach end of list } temp2->Next = temp; } ++locationCount; // increment counter for number of records in list if(!userInputReq){ cout << "Location sucessfully added to the database!
