  • A Question about dereferencing pointer to incomplete type In C programming

    - by user552279
    Hi, can you explain this error for me? Blockquote /////////////////////////////// In my A.h file: struct TreeNode; struct TreeHead; typedef struct TreeNode * Node; typedef struct TreeHead * Head; /////////////////////////////// In my A.c file: struct TreeNode { char* theData; Node Left; Node Right; } ; struct TreeHead{ int counter; char type; Node Root; }; Head Initialisation() { Head treeHead; treeHead = malloc(sizeof (struct TreeHead)); treeHead-Root = malloc(sizeof (struct TreeNode)); return treeHead; } /////////////////////////////// In my Main.c file: Head head; Node tree; int choose =5; head = Initialisation(); (head-Root) = tree; //When compiling, this line has an error: error: dereferencing pointer to incomplete type Blockquote haed-Root will return a Node pointer, tree is also a Node pointer. So why error is dereferencing pointer to "incomplete" type?

  • Probability Question

    - by Juddling
    if i pick 10 numbers from a possible 80. what is the probablity for someone else picking the same 10 numbers as me? or just 4 numbers? or no numbers? i think it's no matches: 10/80 one match: 10*9/80*79 so the formula would be (10!/matches!)/(80!/matches!) is this right? i've only just started doing this at A-level and i need it for a game script i'm making.

  • Another void C# question

    - by Jim Jones
    Have a type in the header files I'm working with called VTVOID it is the type of a struct element and a number of parameters. In the header file defining types is the line #define VTVOID void I read in another discussion the void maps to System.Void however when I plug that into the C# code I get the error "System.Void cannot be used in C# -- use typeof(void) to get the void object." So what type do I plug in? Jim

  • ASP.NET MVC URL/Routing question

    - by Hobbes
    Hello! I am an MVC newbie. I'm trying to get my URLs to look like this: /Corporate/Users/Edit/1 /Corporate/Stores/Edit/17 /Corporate/Contacts/Edit/17 /Store/Contacts/Create /Store/Products/Edit/29 Pretty much like plain-vanilla urls, except with a user type at the front. I'm running into a lot of problems with duplicate controller names, etc. Is there a simple way to do this? I looked briefly at Areas, but this seemed way to complicated.

  • javax.activation.DataSource size question

    - by folone
    How do I get the amount of physical memory, consumed by the DataSource (specifically — ByteArrayDataSource)? I use ByteArrayDataSource (byte[] bytes, String type) constructor, where I get bytes like this: String str = "test"; byte[] bytes = str.getBytes(); Would that be str.length() in bytes? Any other ideas?

  • Basic SQL query question

    - by user318573
    Hello, I have the following query: SELECT Base.ReportDate, Base.PropertyCode, Base.FirstName, Base.MiddleName, Base.LastName, Person.FirstName, Person.MiddleName, Person.LastName FROM LeaseT INNER JOIN Base ON LeaseT.LeaseID = Base.LeaseID INNER JOIN Person ON LeaseT.TenantID = Person.ID works fine, except there could be 0 to 'N' people in the 'Person' table for each record in the Base table, but I only want to return exactly 1 for each 'Base' record (doesn't matter which, but the one with the lowest Person.ID) would be a reasonable choice. If there is 0 rows in the person table, I still need to return the row, but with null values for the 'person' fields. How would I structure the SQL to do that? Thanks. Edit: Yes, the tables are probably not structured properly, but restructuring at this time is not possible - got to work with what is there.

    - by Bruce
    I am working on VC++ compiler. I want to accomplish the following The variables s.AddrFrame.Offset and s.AddrStack.Offset contain the value of EBP and ESP respectively. I want to extract the value of old EBP and the return address.

  • C# Property inheritance question

    - by mcxiand
    Hi all, How do i inherit a property in c# from an interface and give that property other name on the class? For example: public interface IFoo { int Num {get;set;} } public class IFooCls : IFoo { int Ifoo.Num{get;set} } In this case, what the property name in the interface is also the same in the class. What i want is to give other property name on the class but still pointing to "Num" in the interface in this case. In VB, we can do it like this: Public ReadOnly Property UserId() As String Implements System.Security.Principal.IIdentity.Name Get Return _userId End Get End Property

  • MS SQL Query Question

    - by Lp1
    Running MS SQL 2008, and I am definitely a new SQL user. I have a table that has 4 columns: EmpNum, User, Action, Updatetime A user logs into, and out of a system, it is registered in the database. For example, if user1 logs into the system, then out 5 minutes later, a simple query (select * from update) would look like: EmpNum User Action Updatetime 1 User1 I 2010-01-01 23:00:00:000 1 User1 O 2010-01-01 23:05:00:000 I'm trying to query the Empnum, User, Action, I(in time), O(out time), and the total time. Any help or a point in the right direction, and I would be eternally grateful. :)

  • Simple iPhone tally method question

    - by Rob
    Just trying to create a simple method that counts up 1 on the tally when the button is pressed. My knowledge is extremely limited and I am pretty sure that my problem is somewhere in the method implementation: -(IBAction) updateTally:(id) sender { NSString *text; int total = 0; total = total + 1; text=[[NSString alloc] initWithFormat: @"%i", total]; lblTally.text = text; } I have done the necessary interface declarations for the lblTally UILabel and the updateTally method. I suspect that there is some sort of an NSString/int/%i/%@ mixup that I am making but I'm not sure how to fix it. When I run the program as it currently is it displays a 0 in the lblTally label field on the iphone. When I press the button it then displays a 1 in that field. However, if I continue to press the button - nothing happens.

  • Java - Reg. Ex. File Question

    - by aloh
    I'm grabbing lines from a text file and sifting line by line using regular expressions. I'm trying to search for blank lines, meaning nothing or just whitespace. However, what exactly is empty space? I know that whitespace is \s but what is a line that is nothing at all? null (\0)? newline (\n)? I tried the test harness in the Java tutorial to try and test to see what an empty space is but no luck so far.
