  • Under what conditions will you get unresolved external symbol for __declspec(dllimport)?

    - by Mark
    I am converting an application to use .dlls and I'm riddled with linker errors stating unersolved external symbol"__declspec(dllimport) public: void __thiscall Rail::SetNextrail(class Rail *)" There is more gibberish at the end of this error message. Why should this happen and how do you fix it? __declspec(dllimport) is being placed with a macro defined as: #ifdef LUDOAI_EXPORT #define DECLSPECAI __declspec(dllexport) #else #define DECLSPECAI __declspec(dllimport) #endif

Ie, can I make the #special p expand over the top of 'Things'? As I currently have it set up #special won't ever grow outside the 220px wide td. Any ideas?

  • Passing XML data and user from coldfusion page to .NET page

    - by Mark Rullo
    I'd appreciate some input on this situation, I can't figure out the best way to do this. I have some data that's being prepared for me in a ColdFusion app and in an IFrame within the CF app we want to display some graphs (not strictly an image, it's an entire page) being generated on the .NET side of things. I'd like to pass XML data from the CF side to .NET as well as the user. On the .NET side I'm putting the data in a session so the user can sift through it without the need to have it re-queried and re-passed from CF. What I've tried: Generating XML with CF, putting it in a hidden form field, auto-submitting (with JS) a the form to the .NET side. The issue I'm having with this approach is the encoding being done on the form post. The data has entries like <entry data="hello &amp; goodbye">. It's an issue because it's being URL encdeded, Posted, and when I get it on the .NET side I get <entry data="hello & goodbye"> which isn't properly formed XML. What I'd like to avoid: An intermediary DB approach (dropping the data in a DB on CF, picking it up with .NET) I'd like to only display what is passed to the page. I have security concerns with the data, it's very sensitive. Passing the data to a webservice, returning a GUID, forwarding the user with a URL Parameter to access the passed in data. I think that'd be risky if someone happened on a link to that data. I can't take that risk. I was thinking of passing the data with JSON, but I'm very unfamiliar with it. Thoughts? Thanks for your time folks.

  • Is there anyway to show a hidden div in the last row of a html table

    - by oo
    i have an html table. here is a simplified version: <table> <tr> <td><div style="display: none;" class="remove0">Remove Me</div></td> </tr> <tr> <td><div style="display: none;" class="remove1">Remove Me</div></td> </tr> <tr> <td><div class="remove2">Remove Me</div></td> </tr> </table> i have javascript that clicks on Remove Me in the last row and it deletes the html row using: $(this).parents("tr:first").remove(); the issue is that when i remove this last row, i also want the "Remove Me" text to now show up on the second row (which is now the new last row). how would i show this div so that it would dynamically show the "remove me" from the new last row?

  • jquery select one class from many

    - by simnom
    Hi, I'm trying to achieve the following functionality. Within a form I have multiple fields with the class name .inputField if one of these fields is selected then the div associated with that element should be shown on focus and hidden on blur. However, when I implement the code below on selecting the second element the class is applied to both. Not sure where I'm going wrong?!?!? html markup: <form class="friendlyForm" name="friendlyForm" id="friendlyForm"> <ul> <li> <label for="testField">Test field</label> <input name="testField" value="here" class="inputField" id="testField" /> <div class="helper" style="display: none;">helper text here</div> </li> <li> <label for="testField">Test field2</label> <input name="testField2" value="here" class="inputField" id="testField2" /> <div class="helper" style="display: none;">helper text here</div> </li> </ul> </form> jQuery markup: $('.friendlyForm').find('.inputField').each(function(i) { $(this).blur(); $(this).focus(function() { //Add the focus class and fadeIn the helper div $(this).parent().addClass('focus'); $(this).parent().parent().find('.helper').fadeIn(); }); $(this).blur(function () { //Remove the focus class and fadeOut helper div $(this).parent().removeClass('focus'); $(this).parent().parent().find('.helper').fadeOut(); }); }); Any pointers here would be greatly appreciated. Thanks

  • How to store sorted records in csv file ?

    - by Harikrishna
    I sort the records of the datatable datewise with the column TradingDate which is type of datetime. TableWithOnlyFixedColumns.DefaultView.Sort = "TradingDate asc"; Now I want to display these sorted records into csv file but it does not display records sorted by date. TableWithOnlyFixedColumns.DefaultView.Sort = "TradingDate asc";TableWithOnlyFixedColumns.Columns["TradingDate"].ColumnName + "] asc"; DataTable newTable = TableWithOnlyFixedColumns.Clone(); newTable.DefaultView.Sort = TableWithOnlyFixedColumns.DefaultView.Sort; foreach (DataRow oldRow in TableWithOnlyFixedColumns.Rows) { newTable.ImportRow(oldRow); } // we'll use these to check for rows with nulls var columns = newTable.DefaultView.Table.Columns.Cast<DataColumn>(); using (var writer = new StreamWriter(@"C:\Documents and Settings\Administrator\Desktop\New Text Document (3).csv")) { for (int i = 0; i < newTable.DefaultView.Table.Rows.Count; i++) { DataRow row = newTable.DefaultView.Table.Rows[i]; // check for any null cells if (columns.Any(column => row.IsNull(column))) continue; string[] textCells = row.ItemArray .Select(cell => cell.ToString()) // may need to pick a text qualifier here .ToArray(); // check for non-null but EMPTY cells if (textCells.Any(text => string.IsNullOrEmpty(text))) continue; writer.WriteLine(string.Join(",", textCells)); } } So how to store sorted records in csv file ?

  • Limiting a search to records from last_request_at...

    - by bgadoci
    I am trying to figure out how to display a count for records that have been created in a table since the last_request_at of a user. In my view I am counting the notes of a question with the following code: <% unless @questions.empty? %> <% @questions.each do |question| %> <%= h(question.notes.count) %> end end This is happening in the /views/users/show.html.erb file. Instead of counting all the notes for the question, I would only like to count the notes that have been created since the users last_request_at datetime. I don't neccessarily want to scope notes to display this 'new notes' count application wide, just simply in this one instance. To accomplish I am assuming I need to create a variable in the User#show action and call it in the view but not really sure how to do that. Other information you may need: class Note < ActiveRecord::Base belongs_to :user belongs_to :question end class Question < ActiveRecord::Base has_many :notes, :dependent => :destroy belongs_to :user end

Please suggest me best and optimized query for this. UPDATE: if there is no open time and close time for school then college_open_time and college_close_time has to be returned( not to be filled in database,just return) as school_open_time and school_close_time. and there always must be college_open_time and college_close_time for a given day MORE UPDATE: i m using below query SELECT college_open_time,college_close_time ,school_open_time, school_close_time FROM tbl_college LEFT JOIN tbl_school ON school_owner_id=college_owner_id WHERE college_owner_id='".$_session['user_id']."' AND college_day='".date('l',time())."'"; it return single row (left hand having some value and right hand having blank value) when there is no row of a given day in table_school, BUT display seven rows with same value on left hand side(college_open_time, college_close_time) and 6 blank row on right hand side (school_open_time and school_close_time) i need only one row when both table have a row of a given day but using above query take only first row of corresponding table_school where school_owner_id is 50(let), it not see the condition that school_day name should be given day

  • Specified argument was out of the range of valid values. Parameter name: utcDate

    - by Rob
    Our logs show hundreds of these errors after our deployment if users are on the site. Anyone know what this means and how to fix it? Notes: We are using msdeploy, IIS 6 I recently noticed that our web server's time is about 10 minutes behind the real time, I think that may have something to do with it. If I log into our site, seems like any file that depends on a WebResource or ScriptResource type file doesn't look right. Seems to fix itself after an IIS reset

  • How to automatically reseed after using identity_insert?

    - by Earlz
    Hello, I recently migrated from a PostgreSQL database to a SQL Server database. To switch the data over I had to enable IDENTITY_INSERT. Well come to find out that I get all sorts of strange errors due to duplicate identity values(which are set as primary keys) upon doing an insert in any of the tables. I have quite a few tables. What would be the easiest way of automatically reseeding the identity of every table so that it is after max(RID)?

Can someone provide a simple code example of how I can get my code to work the way I want it to? Thanks!

  • How to link latest stable version of libCURL using vc++2010

    - by Rollie
    On 2 separate machines in completely different environments (work, home) I've been unable to compile libCURL out of the box. Running nmake -f Makefile.vc mode=dll VC=10, I get an unresolved external symbol errors for _IdnToAscii and _IdnToUnicode. I believe the definitions are in Normaliz.lib, which is referenced in LFLAGS, but it either isn't finding it or the version I have doesn't have those functions. But I don't see any option to download this file...anyone have a good solution short of commenting out the 2 lines that use these functions?

  • Execute client & server side code with one click?

    - by Abu Hamzah
    i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click. using : asp.net web form i have a web form with few textbox and a gridview control and a button. if i click on the button i am executing two things 1) asynchronously get data from server to client (working great) and able to display the data in the textboxes. 2) same click i want to bind the gridview. <asp:Content ID="Content2" ContentPlaceHolderID="cphMaster" runat="server"> <asp:Label runat="server" ID='Label1' >Id:</asp:Label> <asp:TextBox ID="txtId" runat='server'></asp:TextBox> <asp:Button ID="btnSubmit" OnClientClick="LoadDataById();" runat="server" Text="Submit" onclick="btnSubmit_Click" /> <br /> <br /> <asp:TextBox ID="txtName" runat='server'></asp:TextBox> <br /> <asp:TextBox ID="txtPurpose" runat='server'></asp:TextBox> <br /> <br /> <asp:GridView ID="GridView1" runat="server"> </asp:GridView> </asp:Content> server side protected void btnSubmit_Click(object sender, EventArgs e) { GridView1.DataSource = laodData(int.Parse(txtId.Text)); GridView1.DataBind(); } Jquery: function LoadVisitBasicByVisitId() { ContactServiceProxy.invoke({ serviceMethod: "GetDataById", data: { request: request }, callback: function(response) { processCompletedContactStore(response); }, error: function(xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); return false; } recap: 1) jquery script execute asynchronously to get data from server to client and display in the textboxes 2) server side code to bind the gridview.

  • How can I change the color of build output in a shell window?

    - by Tim Gradwell
    I have a build process which runs from a batch file. It produces a large volume of text. Sometimes it prints the word "Error" or "Warning" followed by a message. The errors and warnings are getting lost among a sea of text. Can I highlight those words in a different color, maybe in a dos window, or a cygwin shell window, possibly by piping them through some string manipulation program before posting them to the screen? Thanks.

  • Looking for a Python IDE with good support for libraries (Twisted).

    - by Omega
    I'm looking for a Python IDE that can help me easily locate and manage and use the libraries on my system (Ubuntu). Specifically Twisted. Code completion is important including the symbols I import. (I've so far had a look at PyDev as well as OpenKomodo, but while both offer code completion for default Python concepts, I wasn't able to get either to import Twisted into my project and was thus getting reference errors.) Usual disclaimer: I don't like EMACS or vi, please, nothing regarding those.

  • How to handle product ratings in a database

    - by Mel
    Hello, I would like to know what is the best approach to storing product ratings in a database. I have in mind the following two (simplified, and assuming a MySQL db) scenarios: Scenario 1: Create two columns in the product table to store number of votes and the sum of all votes. Use columns to get an average on the product display page: products(productedID, productName, voteCount, voteSum) Pros: I will only need to access one table, and thus execute one query to display product data and ratings. Cons: Write operations will be executed in a table whose original purpose is only to furnish product data. Scenario 2: Create an additional table to store ratings. products(productID, productName) ratings(productID, voteCount, voteSum) Pros: Isolate ratings into a separate table, leaving the products table to furnish data on available products. Cons: I will have to execute two separate queries on product page requests (one for data and another for ratings). In terms of performance, which of the following two approaches is best: Allow users to execute an occasional write query to a table that will handle hundreds of read requests? Execute two queries at every product page, but isolate the write query into a separate table. I'm a novice to database development, and often find myself struggling with simple questions such as these. Many thanks,
