Instead of doing a direct link with the database why don't you write an SQL query in which you can filter the data any way you want then fill the combo box with the result set. [SELECT DISTINCT](http://www.w3schools.com/sql/sql_select.asp) profile_name will remove duplicates

>>PrintString(*array); That is not an array of strings like you originally declared because it only has one asterisk. All that takes is one character array.

Thanks for using code tags, but the code you posted contains no carriage returns '\n', and that makes it impossible to copy. Learn to use your compiler's debugger so that you can step through the problem one line at a time and see what it is doing.

Yes. Do you have a console or GUI program. What compiler and operating system. Its basically nothing more than a loop [code] int main() { std::string username, password; bool done = false; while( !done ) { // ask for user name and password. If corect set done to true, otherwise …

where is the implementation code for that constructor? BTW: it is almost never ever the fault of the compiler.

7/19 correct. I answered every question with using deadly force Rambo style.

Is it possible to allow someone to add new items to a poll after it has been initially created ? Often times I see that posters have other things they would like to add to the poll or something the OP forgot and would like to add.

download VC++ 2008 Express and that problem will be solved. With the 2005 version you also have to download the Windows Platform SDK, which is pretty large. And it is somewhat complicated to set that compiler up so that it will compiler windows programs. Microsoft fixed those problems with 2008.

The answer is in the [URL="http://www.cplusplus.com/reference/iostream/fstream/open.html"]open() function [/URL]-- see the flags for the second argument. If you want all writes to go at the end of the file the second argument should be ios::ate. Or you could do seekp() first to set the file pointer to end-of-file. But ios::ate is …

depends. If the code uses normal win32 api functions such as CreateFile() to open the com port, then you shouldn't have to change a thing. The device driver will make it transparent to your program.

do you know if $HISTFILE actually exists in the environment ? My guess is that getenv() returns NULL and your program is not checking for a NULL return.

>>stat = canWrite(hnd, 1234, size, 8, canMSG_EXT); what is the 1234 and 8 for? sizeof(size_t), which is an unsigned int, if 4 on most 32-bit computers, not 8.

you mean you want the structure to look like this: [code] struct exam { int examid; float total; }; [/code] You will have to make a lot of code changes to do that because total is no long an array of ints. I suppose instead of push_back(123) just add 123 …

Simple -- you already have the ranges declared as integers or floats in lines 84-94, now all you have to do is read their values from the input file. You don't have to change another thing. Do that right after line 103 in the post above and it should work …

I agree with Dani. I never heard of Moneybookers either. Just the name sounds a little slizzy to me.

lets say you want an array that can hold up to 10 divisors. Then you would declare it like this: In addition to declaring the array the code below will initialize all elements with 0. [icode]int divisors[10] = {0};[/icode] Each of the elements of the array are numbered 0, 1, …

>>while (a != 'A' || 'B' || 'C') wrong way to code that [icode]while (a != 'A' && a != 'B' && a != 'C')[/icode] or this [icode]while( a < 'A' || a > 'C')[/icode]

The problem is in some code before those functions. Most likely you forgot the function's closing brace }. That makes the compiler think that the next function is being nested inside the previous function. Count the braces and make sure there is a } for every {.

those warning could be safely ignored -- but to remove the warnings check the return value of strlen() -- it returns and size_t (an unsigned int), and you are attempting to compare it with an int. In the case of line 124 just change the data type of variable i …
