It appear you are declaring the same object in two *.cpp files. That will happen if you declare something in a header file then include that header file in all *.cpp files. What you need to do to corect that is declare it with the [b]extern[/b] keyword in the header …

To change the value you have to completely rewrite the entire file. You will have to write the file back out in the same format from the data that is in the Form.

allocate and top the string first then reset pointer a [code] char* temp = new char[n]; char* p = temp; memset(temp,' ',n); temp[n-1] = 0; //null terminate memcpy(temp, a, strlen(a)); a = temp; [/code]

1) open the file [code] FILE* fp = fopen("myfile.txt"); [/code] 2) use fprintf() [code] fprintf(fp,"%x", 123); [/code] How difficult was that?? But this is c++, so you should be using the functions in <fstream> [code] #include <fstream> using namespace std; int main() { ofstream out("myfile.txt"); out << hex << 123 …

If you want to set all elements to 0 then you can use memset(). Microsoft compilers implement that function in assembly because the chip has an instruction that will do it, and that is about as efficient as you can get. I don't know how other compilers implement it. Also …

If the classes can be plugged into other projercts without change then make a shared library out of them. That way there is only one set of source files and the projects all link with the same library.

First you have to populate the two arrays dogs and cats. cin might be useful for that. After that is done then use a loop to sum them up

The functions in either stdio.h or <fstream> will do the job equally well, but for c++ most programmers would recommend <fstream> for consistency. If all the characters you want to write are all in one large block of RAM than you would write the file in binary mode, which is …

You can use[URL="http://www.codeblocks.org/"] Code::Blocks compiler[/URL], which is more up-to-date than Dev-C++.

try googling because it will answer many of the questions you have. The solutions are not simple, so you will need basic understanding of C and/or C++ languages.

trimleft() does nothing. After finding the last space you need to shift all remaining characters left. memmove() will do that for you, or you can do it yourself using two pointers.

You posted crappy unrealistic options. You can't learn Windows development without knowledge of either C or C++ (or some other computer language as well). So options B, D and E are impossible assuming you don't want to know about other languages. That leaves only options A and C as viable …

1) delete line 87 because its unnecessary. The function is prototyped in the header file. 2) line 108: time_after is never declared (see spelling on line 89)

Yes because the compiler can't optimize the code. It also makes the program at least twice the size it needs to be.

Contract your nearest military installation and ask them. If you don't know who to contact then start with the Base Commander's office. You don't have to speak to the commander, but anyone on his staff should be able to point you in the right direction.

Depends on the circumstances. Most of the time you will want loop counters to start at 0 because all arrays in C and C++ are 0 based, not 1 based. So the index number of the first element of any array is always 0. For consistency sake I always start …

If you did your googling then you had to come across [URL="http://www.geocities.com/Jeff_Louie/safearray.html"]this article[/URL]. It illustrates an array of BSTRs, but the syntax is nearly the same for any POD (plain-old-data) type.

>>any other ideas will still help Freaky's solution looks like a sure winner to me :) The only problem I see is if you unplug your computer before properly shutting down the program so the data can be saved.

Don't know the answer to your question until I know the contents of the text file. Without that knowledge, generally I would use fgets() to read a line, then parse it into its individual parts into the structure.
