 | A good place to begin is [here]( http://winprog.org/tutorial/). That will only scratch the surface of MS-Windows programming. A better way to learn it is to buy a book from amazon.com. I also love www.codeproject.com, probably the largest repository of free MS-Windows code on the internet. |
| | line 5, form2. That is not the same as the original instance of form1, which is why you don't see the changes when from1 returns. What you want to do is to set a public int in form2 that can be read by form1 when it regains control, then use …  |
| | > I put the -9's there as sentinel values if that's right. I don't think you need that. The instructions states the exact number of grades in each category, so all your program has to do is read that quantity of numbers. No need for a sentinel value. setProg() -- … |

 | Re: XKCD Web Comics Cool! Some of those are very true, especially the line graphic of alcohol consumption vs progframming skill.  |
| | If DATA is defined as int, struct * can not be assigned the value of int without a typecast. line 19: You can not free() individual elements of an array. The number of elements of an array are fixed when the array is declared and can not be changed. The …  |

 | Only limited way can class A use class B before class B is declared, class A can declare a pointer to an object of class B but that's about the extent of it. ~~~ class B; // pre-declare class class A { public: B* b; // declare a pointer to …  |
 | For the second part you could use a regexp (regular expression) library so that you would search for either b*d or b?d, which * means any number of characters, and ? means only one character. So b?ne would find both bone and bane, whiew b*e whould find all the strings … |
| | You can not concantinate string2 to the end of string1 because (1) string1 is a string leteral so most likely its stored in read-only memory, and (2) there is not enough room in string1 to contain both strings. In main() try this: char string1[80] = "my"; The above allows you … |
| | Sort both strings so thzt the characgters appear in the same order in both strings, then eliminate duplicate characters. After that, convert both strings to the same case, e.g. upper or lower, doesn't matter which. Finally call strcmp() to compare them. Another method is to count the number of occurrences … |
 | I'd like to see the list of reputation comments in our Profile similar to the one that was in vBulletin. |
| | You can't actually delete an element from the array. All you can do is mark it as an unused element. There are numerous ways to do that and it doesn't really matter which one you use as long as your program recognizes the element as being unused. For example, in … |
| | use brackets or declare ofstream object before the switch statement. ~~~ switch(x) { case '7': { ofstream filestream("Test.txt",ios::out|ios::app); //... } break; case '8': cout<<This is a test."; break; } ~~~ |
| | >This is what I have so far, where I'm I going wrong? Don't know. What kind of problems are you having? If compiler error(s) then post the first two or three errors including the line numbers on which they appear. |
| | Learning a programming language is not easy for most people, especially if you try to learn it by yourself. Forturnately, you have lots of help such as DaniWeb on the internet today. A good place to start is by reading one of the books suggested in this thread: http://www.daniweb.com/software-development/cpp/threads/70096/c-books Take … |
| | >Hey guys, I am making a simple c++ compiler with Visual Studio 2010, but I am stuck on the converting it to assembly bit(with c++ coding). The compiler will generate an assembly code listing for you. All you have to do is go to Projects --> Properties (at the bottom … |
| | >Your requirements are pretty steep (challenging) for someone brand-new to C++ My guess is that course is NOT intended for beginners. Most likely an advanced programming course for which the OP does not have the prerequisites. If it is a beginner's course then fire the instructor and drop the course. |
| | How much or little work that is going to be is almost impossible for anyone to say without seeing the actual code, knowing the differences between the two versions of the files, and which functions your program uses. For example, are all the SDL include files listed in one single … |
| | Re: question Alot will depend on how much c++ you already know. Do you know about classes and <vector> yet? Start out by generating the two required text files. Then write a very simple program that opens and reads them. Don't get overwhelmed by the complexity of the program. Code, compile and … |

 | Re: New Moderators >And we're forgetting one ... Congrats to Sanjay for being promoted to co-Administrator! :) Does that mean we get to curse at him when things don't go right :) LOL Just kidding. Congratulations Sanjay. You have been one of the best contributors here and you deserve the promotion. And congrats …  |
| | The easiest way is not to return the matrix at all, but declare it in main() and pass it in as a parameter. This works becuse arrays are always passed by reference, never by value. ~~~ void matrixGenerato(int matrix[][3]) { } int main() { int matrix[3][3]; matrixGenerato(matrix); } ~~~  |
| | Re: Constructor C++ >The problem is that winner will never have the '1' or '0', it will have character that has ascii value 1 or 0 Huh? '1' has an ascii value of 48, 1 does not. Unless I missed something I don't see that as a problem with that program as long … |
| | Another possibility -- might need a new battery. They don't last forever.  |
| | Re: strcmp question strcmp() won't work for you because it expects an exact match. you can call strstr() to see if the line contains "-hello". If it does, then check for anything following to see if something other than spaces. You may need to do additional checks if there is a chance that … |
| | *.txt and *.ini files should be simple and straight forward to process as you described in your post. I don't know how the subject of this thread fits into that. *.docx files are more problematic because the are binary files, not text files. Other languages such as VB.NET and C# … |
| | Your first error is assuming there are exactly 20 characters in the line. What if there are 25 spaces? Or only 1 character and it is a space? To solve that problem check for end-of-line terminating character '\0'. ~~~ int empty_line(char line[]) { int i; for(i = 0; line[i] != … |

| | Re: Pie menu You might check [CodeProject](http://www.codeproject.com/search.aspx?q=pie+menu&x=0&y=0&sbo=kw) to see if they have anything useful for you. That site has the largest repository of C/C++ code for MS-Windows that you can find on the internet. Well work bookmarking if you use that os. |
| | I don't really care one way or the other. I think the old style of Link button was easier and more intuitive to use, but I'll get accostumed to the way it is now. About the only thing I use is code tags, Link, Quote, and on rare occasions List. |
| | 1) Use 64-bit version of VC++, I think its version of fstreams support huge files 2) call win32 api read/write functions which support huge files (see ReadFile() and WriteFile()) |
| | You need a while loop to find the correct spot. On line 5 just do a return. Then start the while loop to find out where to put the new node, like lines 30-32. temp -> price = price; if((*head) == NULL && (*tail) == NULL) { temp->next = NULL; … |
| | what operating system and compiler do you have in mind? And do you want a command-line text editor, something like edlin.exe or a graphical program like Notepad.exe? |
| | Why did you create so many threads for the same problem? It just confuses people. see my answer here: http://www.daniweb.com/software-development/c/threads/419598/linked-list-sorting |
| | Just use a normal sort algorithm, there are lots of them and google will show you the c/c++ source code for most of them. When its time to swap then just swap the data instead of the whole node. If you are not allowed to do that then you will … |
| | that makes no sense at all -- you can't put if statements in arrays. Post an example of what you want to do. |
| | You reopened (renamed) stdin to be a text file, therefore cin is getting the data from text file intead of keyboard. Check cin for errors. Also check that text file to see that it contains numeric digits, if it doesn't then cin will fail. |
| | Post your program so that we can see what you tried to do. Its likely either 1) the propgram did not compile because of errors, or 2) the program just doesn't do what you thought it should do. But we won't know until you show us your program. |
