  • Weird Excel Formatting

    - by Gage
    Recently a new co-op was hired at our company and has been tasked to run a report. The report queries the database and returns a resultset and from there procedes to create the spreadsheets. Depending on the number of days selected a different number of reports are generated but I do not believe that is relavent to the question. Basically it runs the reports and loops through the resultset but at some point continues to loop through until tow 65536 at which it stops. For Example if the resultset contained 74 records then the first 74 rows would appear normally (formatted yellow) while everything after that would also be formatted yellow although it should be left alone. I am inheriting this code as I to am a new co-op. Apparently this only happens when a "change of guards" happens (New co-op has to run the report).` DoCmd.SetWarnings False DoCmd.OpenQuery ("DailySummaryQueryMain") strSQL = "SELECT * FROM DailySummaryMain" Set rs = CurrentDb.OpenRecordset(strSQL) DoCmd.Echo True, "Running first Report" If Not rs.EOF Then rs.MoveFirst Do While Not rs.EOF And Not rs.BOF xlapp.Range("A" & i).Value = rs.Fields(0).Value xlapp.Range("B" & i).Value = rs.Fields(1).Value xlapp.Range("C" & i).Value = rs.Fields(2).Value Set rs2 = CurrentDb.OpenRecordset("SELECT dbo_StatusType.StatusTypeID, dbo_StatusType.Name FROM dbo_StatusType WHERE (((dbo_StatusType.StatusTypeID)=" & rs.Fields(3) & "))") rs2.MoveFirst xlapp.Range("D" & i).Value = rs2.Fields(1).Value xlapp.Range("E" & i).Value = rs.Fields(4).Value xlapp.Range("F" & i).Value = rs.Fields(5).Value xlapp.Range("G" & i).Value = rs.Fields(6).Value 'count number of outages that start and end on same day If Format(xlapp.Range("F" & i).Value, "mm/dd/yyyy") = Format(xlapp.Range("G" & i).Value, "mm/dd/yyyy") Then dayCount = dayCount + 1 End If xlapp.Range("H" & i).Value = rs.Fields(7).Value xlapp.Range("I" & i).Value = rs.Fields(8).Value xlapp.Range("J" & i).Value = rs.Fields(9).Value xlapp.Range("K" & i).Value = rs.Fields(10).Value xlapp.Range("L" & i).Value = rs.Fields(11).Value xlapp.Range("M" & i).Value = rs.Fields(12).Value xlapp.Range("N" & i).Value = rs.Fields(13).Value 'highlite recently modified rows If rs.Fields(14).Value = "Yes" Then xlapp.Range("A" & i & ":N" & i).Select With xlapp.Selection.Interior .ColorIndex = 36 .Pattern = xlSolid End With End If 'break apart by sector If CInt(rs.Fields(2).Value) = 1 Then row = row1 ElseIf CInt(rs.Fields(2).Value) = 2 Then row = row2 ElseIf CInt(rs.Fields(2).Value) = 3 Then row = row3 Else row = row4 End If xlapp.Worksheets(CInt(rs.Fields(2).Value) + 1).Activate xlapp.Range("A" & row).Value = rs.Fields(0).Value xlapp.Range("B" & row).Value = rs.Fields(1).Value xlapp.Range("C" & row).Value = rs.Fields(13).Value xlapp.Range("D" & row).Value = rs.Fields(4).Value xlapp.Range("E" & row).Value = rs.Fields(5).Value xlapp.Range("F" & row).Value = rs.Fields(6).Value xlapp.Range("G" & row).Value = rs.Fields(7).Value xlapp.Range("H" & row).Value = rs.Fields(8).Value xlapp.Range("I" & row).Value = rs.Fields(9).Value xlapp.Range("J" & row).Value = rs.Fields(10).Value xlapp.Range("K" & row).Value = "" xlapp.Range("L" & row).Value = rs.Fields(11).Value xlapp.Range("M" & row).Value = rs.Fields(13).Value If CInt(rs.Fields(2).Value) = 1 Then row1 = row1 + 1 ElseIf CInt(rs.Fields(2).Value) = 2 Then row2 = row2 + 1 ElseIf CInt(rs.Fields(2).Value) = 3 Then row3 = row3 + 1 Else row4 = row4 + 1 End If 'activate main summary sheet for next outage xlapp.Worksheets(1).Activate i = i + 1 rs.MoveNext Loop` Also I should note that this is all happening within an access database which has its tables linked from SQL. The query is extremely slow to run from which I believe is the use of views but thats neither here nor there. All you have to know is attempting to debug takes an enormous amount of time due to having to wait for the recordset to return. My guess is that its not checking to see if the resultset is empty correctly. Is there a way I could check to see if theres a value is rs.Fields(0) and base it off that maybe? That is the ID column and there should always be a value. I am wondering why rs.EOF isn't catching this though.

  • Database Web Service using Toplink DB Provider

    - by Vishal Jain
    With JDeveloper 11gR2 you can now create database based web services using JAX-WS Provider. The key differences between this and the already existing PL/SQL Web Services support is:Based on JAX-WS ProviderSupports SQL Queries for creating Web ServicesSupports Table CRUD OperationsThis is present as a new option in the New Gallery under 'Web Services'When you invoke the New Gallery option, it present you with three options to choose from:In this entry I will explain the options of creating service based on SQL queries and Table CRUD operations.SQL Query based Service When you select this option, on 'Next' page it asks you for the DB Conn details. You can also choose if you want SOAP 1.1 or 1.2 format. For this example, I will proceed with SOAP 1.1, the default option.On the Next page, you can give the SQL query. The wizard support Bind Variables, so you can parametrize your queries. Give "?" as a input parameter you want to give at runtime, and the "Bind Variables" button will get enabled. Here you can specify the name and type of the variable.Finish the wizard. Now you can test your service in Analyzer:See that the bind variable specified comes as a input parameter in the Analyzer Input Form:CRUD OperationsFor this, At Step 2 of Wizard, select the radio button "Generate Table CRUD Service Provider"At the next step, select the DB Connection and the table for which you want to generate the default set of operations:Finish the Wizard. Now, run the service in Analyzer for a quick check.See that all the basic operations are exposed:

  • Which syntax is better for return value?

    - by Omar Kooheji
    I've been doing a massive code review and one pattern I notice all over the place is this: public bool MethodName() { bool returnValue = false; if (expression) { // do something returnValue = MethodCall(); } else { // do something else returnValue = Expression; } return returnValue; } This is not how I would have done this I would have just returned the value when I knew what it was. which of these two patterns is more correct? I stress that the logic always seems to be structured such that the return value is assigned in one plave only and no code is executed after it's assigned.

  • Passing Reference types by value in C#

    - by Ajit
    I want to pass a reference type by value to a method in C#. Is there a way to do it. In C++, I could always rely on the copy constructor to come into play if I wanted to pass by Value. Is there any way in C# except: 1. Explicitly creating a new object 2. Implementing IClonable and then calling Clone method. Here's a small example: Let's take a class A in C++ which implements a copy constructor. A method func1(Class a), I can call it by saying func1(objA) (Automatically creates a copy) Does anything similar exist in C#. By the way, I'm using Visual Studio 2005.

  • jQuery Validator's "required" not working when value is set at statup

    - by nandrew
    Hello, I have a problem with jQuery Validator. I want to use "required" property on a text input. It doesn't work when input has set value attribute by HTML code (tested on Firefox (3.5), and on IE 8 - on IE it works a bit better). Story: 1. Page loads; 2. value is cleared; 3. focus is changed. 4. Nothing happens but the error message should be displayed; 5. getting back to the field and typing some characters. 6. changing focus; 7. getting back to the field; 8. clearing the field. 9. Error is displayed even before leaving the field. The HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script src="Web/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="Web/Scripts/jquery.validate.js" type="text/javascript"></script> </head> <body> <form id="form1"> <input type="text" id="name1" name="name1" value="test" /><br /> <input type="text" /> </form> <script type="text/javascript"> $(document).ready(function() { var validator = $("form").validate({ rules: { name1: { required: true, minlength: 2 } }, messages: { name1: "bad name" }, }); }); </script> </body> </html>

  • Unexpected key-value behavior in a Core Data Context

    - by ????
    If I create an array of strings (via key-value coding) containing the names of a Managed Object entity's attributes which are stored in the App Delegate the first time, I get an array of NSStrings without any problems. If I subsequently make the same call later from the same entry point in code, that same collection becomes an array of NULL objects- even though nothing in the Core Data Context has changed. One unappealing work-around involves re-creating the string array every time, but I'm wondering if anyone has a guess as to what's happening behind the scenes. // Return an array of strings with the names of attributes the Activity entity - (NSArray *)activityAttributeNames { #pragma mark ALWAYS REFRESH THE ENTITY NAMES? //if (activityAttributeNames == nil) { // Create an entity pointer for Activity NSEntityDescription *entity = [NSEntityDescription entityForName:@"Activity" inManagedObjectContext:managedObjectContext]; NSArray *entityAttributeArray = [[NSArray alloc] initWithArray:[[entity attributesByName] allValues]]; // Extract the names of the attributes with Key-Value Coding activityAttributeNames = [entityAttributeArray valueForKeyPath:@"name"]; [entityAttributeArray release]; //} return activityAttributeNames; }

  • Creating an IF statement for datagrid value

    - by EvanRyan
    This is something I thought would be easier than it's turning out to be. For whatever reason, I can't seem to figure out a way to make what I'm trying to do here work with an If statement: List<int> miscTimes = new List<int>(); for (int i = 0; i < MISCdataGridView1.RowCount; i++) { if (MISCdataGridView1.Rows[i].Cells[2].Value == "Something") { miscTimes.Add(Convert.ToInt32(MISCdataGridView1.Rows[i].Cells[3].Value)); } } return miscTimes; For some reason, I can't get it to like anything I do with the if statement. I've tried converting to string and all of that. How should I go about this?

  • C++ get method - returning by value or by reference

    - by HardCoder1986
    Hello! I've go a very simple question, but unfortunately I can't figure the answer myself. Suppose I've got some data structure that holds settings and acts like a settings map. I have a GetValue(const std::string& name) method, that returns the corresponding value. Now I'm trying to figure out - what kind of return-value approach would be better. The obvious one means making my method act like std::string GetValue(const std::string& name) and return a copy of the object and rely on RVO in performance meanings. The other one would mean making two methods std::string& GetValue(...) const std::string& GetValue(...) const which generally means duplicating code or using some evil constant casts to use one of these routines twice. #Q What would be your choice in this kind of situation and why?

  • Hash default value not being used

    - by ba
    Today I tried the following snippets of code and I don't understand why I get different results between them. As far as I can understand they are the same. One uses the default value off Hash and the other snippet creates an empty array for the key before it'll be accessed. Anyone who understands what's going on? :) # Hash default if the key doesn't have a value set is an empty Array a = Hash.new([]) a[:key] << 2 # => [2] p a # => {} nil p a[:key] # => [2] # Explicitly add an array for all nodes before creating b = Hash.new b[:key] ||= [] b[:key] << 2 # => [2] p b # => {:key=>[2]}

  • ASP.NET MVC Custom Profile Provider

    - by Ben Griswold
    It’s been a long while since I last used the ASP.NET Profile provider. It’s a shame, too, because it just works with very little development effort: Membership tables installed? Check. Profile enabled in web.config? Check. SqlProfileProvider connection string set? Check.  Profile properties defined in said web.config file? Check. Write code to set value, read value, build and test. Check. Check. Check.  Yep, I thought the built-in Profile stuff was pure gold until I noticed how the user-based information is persisted to the database. It’s stored as xml and, well, that was going to be trouble if I ever wanted to query the profile data.  So, I have avoided the super-easy-to-use ASP.NET Profile provider ever since, until this week, when I decided I could use it to store user-specific properties which I am 99% positive I’ll never need to query against ever.  I opened up my ASP.NET MVC application, completed steps 1-4 (above) in about 3 minutes, started writing my profile get/set code and that’s where the plan broke down.  Oh yeah. That’s right.  Visual Studio auto-generates a strongly-type Profile reference for web site projects but not for ASP.NET MVC or Web Applications.  Bummer. So, I went through the steps of getting a customer profile provider working in my ASP.NET MVC application: First, I defined a CurrentUser routine and my profile properties in a custom Profile class like so: using System.Web.Profile; using System.Web.Security; using Project.Core;   namespace Project.Web.Context {     public class MemberPreferencesProfile : ProfileBase     {         static public MemberPreferencesProfile CurrentUser         {             get             {                 return (MemberPreferencesProfile)                     Create(Membership.GetUser().UserName);             }         }           public Enums.PresenceViewModes? ViewMode         {             get { return ((Enums.PresenceViewModes)                     ( base["ViewMode"] ?? Enums.PresenceViewModes.Category)); }             set { base["ViewMode"] = value; Save(); }         }     } } And then I replaced the existing profile configuration web.config with the following: <profile enabled="true" defaultProvider="MvcSqlProfileProvider"          inherits="Project.Web.Context.MemberPreferencesProfile">        <providers>     <clear/>     <add name="MvcSqlProfileProvider"          type="System.Web.Profile.SqlProfileProvider, System.Web,          Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"          connectionStringName="ApplicationServices" applicationName="/"/>   </providers> </profile> Notice that profile is enabled, I’ve defined the defaultProvider and profile is now inheriting from my custom MemberPreferencesProfile class.  Finally, I am now able to set and get profile property values nearly the same way as I did with website projects: viewMode = MemberPreferencesProfile.CurrentUser.ViewMode; MemberPreferencesProfile.CurrentUser.ViewMode = viewMode;

  • Returning Identity Value in SQL Server: @@IDENTITY Vs SCOPE_IDENTITY Vs IDENT_CURRENT

    - by Arefin Ali
    We have some common misconceptions on returning the last inserted identity value from tables. To return the last inserted identity value we have options to use @@IDENTITY or SCOPE_IDENTITY or IDENT_CURRENT function depending on the requirement but it will be a real mess if anybody uses anyone of these functions without knowing exact purpose. So here I want to share my thoughts on this. @@IDENTITY, SCOPE_IDENTITY and IDENT_CURRENT are almost similar functions in terms of returning identity value. They all return values that are inserted into an identity column. Earlier in SQL Server 7 we used to use @@IDENTITY to return the last inserted identity value because those days we don’t have functions like SCOPE_IDENTITY or IDENT_CURRENT but now we have these three functions. So let’s check out which one responsible for what. IDENT_CURRENT returns the last inserted identity value in a particular table. It never depends on a connection or the scope of the insert statement. IDENT_CURRENT function takes a table name as parameter. Here is the syntax to get the last inserted identity value in a particular table using IDENT_CURRENT function. SELECT IDENT_CURRENT('Employee') Both the @@IDENTITY and SCOPE_IDENTITY return the last inserted identity value created in any table in the current session. But there is little difference between these two i.e. SCOPE_IDENTITY returns value inserted only within the current scope whereas @@IDENTITY is not limited to any particular scope. Here are the syntaxes to get the last inserted identity value using these functions SELECT @@IDENTITY SELECT SCOPE_IDENTITY() Now let’s have a look at the following example. Suppose I have two tables called Employee and EmployeeLog. CREATE TABLE Employee ( EmpId NUMERIC(18, 0) IDENTITY(1,1) NOT NULL, EmpName VARCHAR(100) NOT NULL, EmpSal FLOAT NOT NULL, DateOfJoining DATETIME NOT NULL DEFAULT(GETDATE()) ) CREATE TABLE EmployeeLog ( EmpId NUMERIC(18, 0) IDENTITY(1,1) NOT NULL, EmpName VARCHAR(100) NOT NULL, EmpSal FLOAT NOT NULL, DateOfJoining DATETIME NOT NULL DEFAULT(GETDATE()) ) I have an insert trigger defined on the table Employee which inserts a new record in the EmployeeLog whenever a record insert in the Employee table. So Suppose I insert a new record in the Employee table using following statement: INSERT INTO Employee (EmpName,EmpSal) VALUES ('Arefin','1') The trigger will be fired automatically and insert a record in EmployeeLog. Here the scope of the insert statement and the trigger are different. In this situation if I retrieve last inserted identity value using @@IDENTITY, it will simply return the identity value from the EmployeeLog because it’s not limited to a particular scope. Now if I want to get the Employee table’s identity value then I need to use SCOPE_IDENTITY in this scenario. So the moral is always use SCOPE_IDENTITY to return the identity value of a recently created record in a sql statement or stored procedure. It’s safe and ensures bug free code.

  • List of Commonly Used Value Types in XNA Games

    - by Michael B. McLaughlin
    Most XNA programmers are concerned about generating garbage. More specifically about allocating GC-managed memory (GC stands for “garbage collector” and is both the name of the class that provides access to the garbage collector and an acronym for the garbage collector (as a concept) itself). Two of the major target platforms for XNA (Windows Phone 7 and Xbox 360) use variants of the .NET Compact Framework. On both variants, the GC runs under various circumstances (Windows Phone 7 and Xbox 360). Of concern to XNA programmers is the fact that it runs automatically after a fixed amount of GC-managed memory has been allocated (currently 1MB on both systems). Many beginning XNA programmers are unaware of what constitutes GC-managed memory, though. So here’s a quick overview. In .NET, there are two different “types” of types: value types and reference types. Only reference types are managed by the garbage collector. Value types are not managed by the garbage collector and are instead managed in other ways that are implementation dependent. For purposes of XNA programming, the important point is that they are not managed by the GC and thus do not, by themselves, increment that internal 1 MB allocation counter. (n.b. Structs are value types. If you have a struct that has a reference type as a member, then that reference type, when instantiated, will still be allocated in the GC-managed memory and will thus count against the 1 MB allocation counter. Putting it in a struct doesn’t change the fact that it gets allocated on the GC heap, but the struct itself is created outside of the GC’s purview). Both value types and reference types use the keyword ‘new’ to allocate a new instance of them. Sometimes this keyword is hidden by a method which creates new instances for you, e.g. XmlReader.Create. But the important thing to determine is whether or not you are dealing with a value types or a reference type. If it’s a value type, you can use the ‘new’ keyword to allocate new instances of that type without incrementing the GC allocation counter (except as above where it’s a struct with a reference type in it that is allocated by the constructor, but there are no .NET Framework or XNA Framework value types that do this so it would have to be a struct you created or that was in some third-party library you were using for that to even become an issue). The following is a list of most all of value types you are likely to use in a generic XNA game: AudioCategory (used with XACT; not available on WP7) AvatarExpression (Xbox 360 only, but exposed on Windows to ease Xbox development) bool BoundingBox BoundingSphere byte char Color DateTime decimal double any enum (System.Enum itself is a class, but all enums are value types such that there are no GC allocations for enums) float GamePadButtons GamePadCapabilities GamePadDPad GamePadState GamePadThumbSticks GamePadTriggers GestureSample int IntPtr (rarely but occasionally used in XNA) KeyboardState long Matrix MouseState nullable structs (anytime you see, e.g. int? something, that ‘?’ denotes a nullable struct, also called a nullable type) Plane Point Quaternion Ray Rectangle RenderTargetBinding sbyte (though I’ve never seen it used since most people would just use a short) short TimeSpan TouchCollection TouchLocation TouchPanelCapabilities uint ulong ushort Vector2 Vector3 Vector4 VertexBufferBinding VertexElement VertexPositionColor VertexPositionColorTexture VertexPositionNormalTexture VertexPositionTexture Viewport So there you have it. That’s not quite a complete list, mind you. For example: There are various structs in the .NET framework you might make use of. I left out everything from the Microsoft.Xna.Framework.Graphics.PackedVector namespace, since everything in there ventures into the realm of advanced XNA programming anyway (n.b. every single instantiable thing in that namespace is a struct and thus a value type; there are also two interfaces but interfaces cannot be instantiated at all and thus don’t figure in to this discussion). There are so many enums you’re likely to use (PlayerIndex, SpriteSortMode, SpriteEffects, SurfaceFormat, etc.) that including them would’ve flooded the list and reduced its utility. So I went with “any enum” and trust that you can figure out what the enums are (and it’s rare to use ‘new’ with an enum anyway). That list also doesn’t include any of the pre-defined static instances of some of the classes (e.g. BlendState.AlphaBlend, BlendState.Opaque, etc.) which are already allocated such that using them doesn’t cause any new allocations and therefore doesn’t increase that 1 MB counter. That list also has a few misleading things. VertexElement, VertexPositionColor, and all the other vertex types are structs. But you’re only likely to ever use them as an array (for use with VertexBuffer or DynamicVertexBuffer), and all arrays are reference types (even arrays of value types such as VertexPositionColor[ ] or int[ ]). * So that’s it for now. The note below may be a bit confusing (it deals with how the GC works and how arrays are managed in .NET). If so, you can probably safely ignore it for now but feel free to ask any questions regardless. * Arrays of value types (where the value type doesn’t contain any reference type members) are much faster for the GC to examine than arrays of reference types, so there is a definite benefit to using arrays of value types where it makes sense. But creating arrays of value types does cause the GC’s allocation counter to increase. Indeed, allocating a large array of a value type is one of the quickest ways to increment the allocation counter since a .NET array is a sequential block of memory. An array of reference types is just a sequential block of references (typically 4 bytes each) while an array of value types is a sequential block of instances of that type. So for an array of Vector3s it would be 12 bytes each since each float is 4 bytes and there are 3 in a Vector3; for an array of VertexPositionNormalTexture structs it would typically be 32 bytes each since it has two Vector3s and a Vector2. (Note that there are a few additional bytes taken up in the creation of an array, typically 12 but sometimes 16 or possibly even more, which depend on the implementation details of the array type on the particular platform the code is running on).

  • dynamically horizontal scalable key value store

    - by Zubair
    Hi, Is there a key value store that will give me the following: Allow me to simply add and remove nodes and will redstribute the data automatically Allow me to remove nodes and still have 2 extra data nodes to provide redundancy Allow me to store text or images up to 1GB in size Can store small size data up to 100TB of data Fast (so will allow queries to be performed on top of it) Make all this transparent to the client Works on Ubuntu/FreeBSD or Mac Free or open source I basically want something I can use a "single", and not have to worry about having memcached, a db, and several storage components so yes, I do want a database "silver bullet" you could say. Thanks Zubair Answers so far: MogileFS on top of BackBlaze - As far as I can see this is just a filesystem, and after some research it only seems to be appropriate for large image files Tokyo Tyrant - Needs lightcloud. This doesn't auto scale as you add new nodes. I did look into this and it seems it is very fast for queries which fit onto a single node though Riak - This is one I am looking into myself, but I don't have any results yet Amazon S3 - Is anyone using this as their sole persistance layer in production? From what I have seen it seems to be used for storage of images as complex queries are too expensive @shaman suggested Cassandra - definitely one I am looking into So far it seems that there is no database or key value store that fulfills the criteria I mentioned, not even after offering a bounty of 100 points did the question get answered!

  • Converting non-delimited text into name/value pairs in Delphi

    I've got a text file that arrives at my application as many lines of the following form: <row amount="192.00" store="10" transaction_date="2009-10-22T12:08:49.640" comp_name="blah " comp_ref="C65551253E7A4589A54D7CCD468D8AFA" name="Accrington "/> and I'd like to turn this 'row' into a series of name/value pairs in a given TStringList (there could be dozens of these <row>s in the file, so eventually I will want to iterate through the file breaking each row into name/value pairs in turn). The problem I've got is that the data isn't obviously delimited (technically, I suppose it's space delimited). Now if it wasn't for the fact that some of the values contain leading or trailing spaces, I could probably make a few reasonable assumptions and code something to break a row up based on spaces. But as the values themselves may or may not contain spaces, I don't see an obvious way to do this. Delphi' TStringList.CommaText doesn't help, and I've tried playing around with Delimiter but I get caught-out by the spaces inside the values each time. Does anyone have a clever Delphi technique for turning the sample above into something resembling this? ; amount="192.00" store="10" transaction_date="2009-10-22T12:08:49.640" comp_name="blah " comp_ref="C65551253E7A4589A54D7CCD468D8AFA" name="Accrington " Unfortunately, as is usually the case with this kind of thing, I don't have any control over the format of the data to begin with - I can't go back and 'make' it comma delimited at source, for instance. Although I guess I could probably write some code to turn it into comma delimited - would rather find a nice way to work with what I have though. This would be in Delphi 2007, if it makes any difference.

  • Retrieve the Value of An Integer Variable

    - by Abluescarab
    This is probably easily figured out (I feel very stupid right now), but I can't find a solution anywhere, for some reason. Perhaps I'm not searching for the right thing. And maybe it's in some beginner tutorial I haven't watched. Anyway, I was wondering how to retrieve the value of an integer variable in C++? I know you can use cin.getline() for string variables, but I received an error message when I attempted that with an integer variable (and rightfully so, I know it was wrong, but I was looking for a solution). My project is a Win32 console application. What I'm trying to do is ask a user to input a number, stored in the variable n. Then I take the value of n and perform various math functions with it. In my header file, I have string, windows, iostream, stdio, math, and fstream. Do I need to add another library? There's not much more to tell. I can post my code if I must. EDIT: cout << "TEST SINE"; cout << "\nPlease enter a number.\n\n"; cin >> n; break; Here's the code I'm trying to use. Is this all I need to do? If so, how do I incorporate the variable so I can test it using sin, cos, and tan? Yet again, thanks ahead of time.

  • How do I assign a number value to a non-numerical value in Excel

    - by Keyslinger
    Greetings I have an some survey responses with values like "VU" for "Very Unlikely" and "S" for Sometimes. Each survey response occupies a cell. For each cell containing a survey response, I want to fill another cell with a corresponding number. For example, for every cell containing "VU" I want to fill a corresponding cell with the number 1. How is this done?

  • XUL: Printing value from SQL query without using value attribute

    - by Grip
    I want to print the results of an SQL query in XUL with word-wrapping using the description tag. I have the following code: <grid> <columns> <column flex="2" /> <column flex="1" /> </columns> <rows datasources="chrome://glossary/content/db/development.sqlite3" ref="?" querytype="storage" > <template> <query>select distinct * from Terms</query> <action> <row uri="?"> <description value="?name" /> <description value="?desc" /> </row> </action> </template> </rows> This works for printing the data, but since I'm using the value attribute of description, there's no word-wrapping. I don't understand entirely what I'm doing with the value attribute, but I don't seem to be able to get the values of my SQL query in any other way. So, how could I get those values without the value tag? Thanks.
