 | Desktop boot problems are difficult at best. Laptop boots are further complicated by power issues. First things first. I will assume you have an external monitor jack on the laptop somewhere. Hook this up to an external monitor and this will help eliminate the display. If the problem is the …  |
| | Esteemed folks of Daniweb, I find myself in a small quandry. I am part of a test organization working to test a piece of software that the developer does not feel needs the level of test we provide. My issue is this: As we all know, if you change code … |
| | Re: Circle algorithm Tyra, Folks at this site are more than happy to help. Having said that I have to tell you that they expect an attempt at coding, no matter how basic before they will help. |
| | I wonder, now in 2011 with Snow Leopard, if this still works? OlyComputers is correct, this will violate the MacOS license agreement. The poster indeed would have to have gotten lucky with hardware because the biggest difference is in the proprietary driver code Apple provides. My personal curiosity is how … |
| | I'm looking for a line (or more) of VBA that would tell me how to set the "required" property of a field to "No" instead of "Yes" Just so you have the context, I'm helping someone write a module that imports data into an Access database. Of course, sometimes a … |
 | RAM configurations are motherboard dependent. While the CPU may be the beating heart of your system, consider the motherboard to be the core body of your system. The bridge chips (north and south) are responsible for all the interfacing and addressing that goes on. Each manufacturer will have a list … |
| | Good morning folks...I have a pseudo concept question. I have a trio of unix text files that I need to load into an Access database, and then do a comparison for matches (knowing one field will never match). My original idea was to create a VB application to parse the … |
| | Crap...just saw the date on this...excuse me. |
| | The quickie troubleshooter's way to determine screen or motherboard is to hook up an external display. If the display comes on...it's the lcd on your laptop. If it doesn't...bye bye video capability on your motherboard. Your battery definitely sounds shot. Since you seem to be having boot issues, it may … |
| | Try going to the motherboard manufacturer's website. They will have a list of compatible CPUs and RAM configurations. Nothing else should have a problem as long as the video card slot is capable of the video card capabilities. The motherboard manufactuer's website should tell you that as well. |
| | Without being there to actually fool with the system, have you had the processor checked out? Meaning, are you sure it isn't dead to begin with? Just something to check out before you spend any real money. |
| | I'm not sure how to ask this and I'll probably sound a little stupid, but bear with me. How does a "membership" website store member data? Is it done with a database? Does it store the information in a flat file as pages that can be edited later? I see … |
| | I'm doing a lab where I must use three sorting methods, then merge sort the three arrays. While separating the larger array, I'm getting a "run time check error #2 stack around the variable x was corrupted: It does this for y and z as well. I think it is … |
| | Re: Data Structures You are correct V, data structures covers all those things. I am currently in a DS class myself and use MS Visual Studio 2005, although now many schools probably use 2008 by now. I'm not sure how your instructor will want you to do things, but mine does not allow … |
| | How do you delete the front cell of an array in an array based circular queue? Here's the Queue cpp functions [code] #include <iostream> #include <string> #include "Contributor.h" #include "myQueue.h" using namespace std; myQueue::myQueue() { front=0; rear =0; Index=0; size= 0; ArrayQ[10]; } myQueue::myQueue(const myQueue &CCmyQueue) { for(int i=0;i < … |
| | How would you do either or both (enqueue contributor objects or pointers to the contributor objects) I guess would be my question. As a beginner as well, I'm not sure how you would pass either into the function. I copied the code and started changing how it's done and no … |
| | I'm having trouble getting my delete function to work for a singly linked list. If I try to delete anything other than the entire list, it deletes everything up to that node. I know there is something wrong with it, but I can't tell what it is. I would like … |

 | two things you can do from a newbie point of view a) if you're using MS Visual Studio, try the menu option "Start without Debug" which will leave the screen up after the program finishes until you "press any key to continue" b) another thing you can do is put … |
| | I have a small question, why do you use the void destroyp function when you have a class destructor that appears to do the same thing? And not to beat a dead horse as AD is an expert, but I too saw the including of namespace in the main, but … |
| | Yes folks me again, but if I don't struggle through, I don't learn it. I'm constructing my main (no interactivity at this point), and when I start to declare/create my first object, it doesn't like the string portion of the input and tells me this: error C2664: 'Contributor::Contributor(std::string,double,gender,int)' : cannot …  |
| | My professor has assigned a lab that we will later be using to learn how to abuse the various types of data structures. In this first lab he asks for the default constructor, a copy constructor, and an overloaded constructor to accept the appropriate data, which you'll see in a …  |
| | I'm trying to create a contributor class with one enumerated type. I took the member functions from the header and put them in a cpp, but I get an error for the enumerated type when I try to compile. Is it because I haven't written a code body for that … |
| | This one actually tells me visual studio has a problem and needs to close this code. I'm sure it's in the insert/write section, but I'm not sure what I did wrong. I'll post the rather simple cpp below it. [code] #include <iostream> using namespace std; template <class T> class list … |
| | If you grab this code and run it, you'll see what I mean. The second half doesn't run, and when I can get it to run, it's all completely wrong. I'm trying, but I'm tired and just want to get it done...lol. The encrypt and decrypt are a separate cpp … |
| | If this is the original class: [code] class StorageBin { public: StorageBin(); ~StorageBin(); void PutInBin( int Item, int Location); int ReturnFromBin (int Location); bool FindInBin(int Item); void DisplayBin(); private: int *pBin; int NumberInBin; int BinSize; }; [/code] Would this be the correct conversion to make it a template? [code] Template …  |
| | When I'm opening a file, is it the file that is text or binary or is it the stream that can be text or binary? Also, when I close a file is that when the stream object is destroyed?  |
| | I'm being asked to make my default constructor "interactive" by having it prompt for an input and store the three phone number pieces you see below. They are strings, and they get called for display in main with the telnumber yournumber piece of main. How would one do that? [code] … |
| | I have the function below in three base classes, one base, then one derived, and another derived from the second. I'm getting external resolution errors when I try to build it. [code] virtual void printtostream(ostream& out); //Since it is a virtual function the above was not defined in any of … |
| | I have a "two stage" inheritance piece I'm writing. The overall class is telnumber, the worknumber is derived from telnumber, and billnumber is derived from worknumber. The problem is in in my billnumber.cpp. In the main there are two lines referring to the billnumber class with only 4 parameters, and … |
| | 3.6 * vector_a; why can I not implement this binary operator as a member operator of a class Vector? [code] class cycle { cycle(); ~cycle; pedal(); }; class bicycle { bicycle(); ~cycle; pedal(); }; bicycle *bikeptr = new bicycle; cycle cycleptr=dynamic_cast <cycle>bikeptr; cycleptr->pedal(); [/code] Okay, here are the questions I … |
| | I have some questions, some might seem kind of dumb, but we're studying overloading operators and inheritance/polymorphing. I'm having trouble finding some references on some things to show me how to do this stuff or why I'm doing it a certain way. what kind/type of binary operators can I use …  |
| | they've actually given you the psuedocode for it, if it helps to get you started, just pick two numbers and do the math operation on paper and that will help you write your functions...make sure you use the correct operators indicated by the results the psuedocode asks for. Your instructor … |

| | I'm having a little problem with a conversion error during compile. Here is the code: [code] #include <iostream> using namespace std; class costOfItem { public: costOfItem(float i_cost); void printMe(); private: const float price; }; // Free functions void displayPrice(costOfItem z) { z.printMe(); } void displayRefPrice(costOfItem &z) { z.printMe(); } void … |
| | Look at the errors you are getting. They concern the operators << and >> and then read the text after them...ostream. As someone else stated, you are also missing a namespace, or at least the specific portions of the namespace that you need. |
| | I've been given an assignment to write code for a sphere class. Now the point of this lesson is really formatting I/O, so they've given some member functions for the class. The problem is I don't know what they are all for. I've included them below and what I think … |
| | How do I prevent the user from entering characters when a float is required? I'm using a bool for valid entry so if they enter text it sends my loop running |
| | In my cdrom class I have a member function called returncost, and a private data member cost. [code] float cdrom::returncost() { return(cost) } [/code] Later, in a free function I call that member function to calculate a total cost and average cost. [code] void showcosts (cdrom &cd1, cdrom &cd2, cdrom … |
| | If I have a class called cdrom, and one of the member functions is loadinfo, what is the difference in these calls? cd1.loadinfo cd1->loadinfo I ask because my compiler is choking on the first and actually asking me if I meant to do the second. |
| | How does one declare a string as a data member in a class? I tried it this way, but my compiler says that's not it [code] class cdrom { public: cdrom(); void loadinfo(); float returncost(); void displayinfo(); void changedata (); private: float cost; string name; string cdtype; }; [/code] |
| | Okay, figured that much out but I'm getting compiler errors on my object (which has data members from another object) [code] void statistics (int rolls[];int rollsize; int rollresults []) threedice tryerluk; rollsize=200; rolls[rollsize]; rollresults[16]; for (int i=0;i<201;i++) { tryerluk.rollem(); rolls[i]=tryerluk.getsumFaces(); }void statistics (int rolls[];int rollsize; int rollresults []) threedice tryerluk; …  |
| | I have my two classes built, one actually uses the other as a data member. Now I need to call that object to fill an array and don't know the syntax to do it. The two classes are in this thread [url]http://www.daniweb.com/forums/thread114985.html[/url] The function prototype looks like this [code] void … |
| | I'm trying to construct a semi simple dice rolling project. I have two classes, onedie and threedice. The threedice class looks like this: [code] class threedice { public: void rollem(); int getsumFaces(); private: onedie die1; onedie die2; onedie die3; }; [/code] Now, when I try to code the two functions … |
| | A semi official definition of istringstream: istringstream provides an interface to manipulate strings as input streams. The objects of this class maintain internally a pointer to a stringbuf object that can be obtained/modified by calling member rdbuf. This streambuf-derived object controls a sequence of characters (string) that can be obtained/modified … |
| | I'll probably gain you some corrections to my post that will give you insight, but as a new guy I can tell you a couple things. I'm not sure why you chose int for main, you could use void as you are only defining and outputting character strings the first … |
| | I'm trying to write a while loop to terminate a program when asked if you want to enter another name and the answer is no (or a number since I'm using character strings) My first idea was to check the 0 element of the first name part asked for, but … |
| | I would agree with Vernon. AD helped me out quite a bit in this respect. What you can do is create a separate cpp file for your functions if you don't want to do it on the same "page" as your main. The way I have been doing it (yes … |
