If you know another language it prolly won't take you too long. I would say 3-4 months if you already know Java.... It took me a couple of years to get a decent knowledge of c++, but that was on and...

A simple way would be to use the clock() function: http://www.cppreference.com/stddate_details.html#clock



int nStart = clock() / CLOCKS_PER_SECOND;
//Execute code to time here
int nTime =...

You could clear the screen using



#include <iostream>
using namespace std;
//..
void main()
{

If the user will be modifying the shapes it's so much better to store the shapes as vectors (i.e. by storing the co-ordinates of the vertices).

Having said that, it is easy enough to apply...

Use gluCylinder() to draw the cylinder, then apply the picture as a texture. If you want a full cylinder use gluDisk() to draw the disks on the ends.

Use
unsigned char m = (unsigned char)x;

The data format in the P5 data files is dictacted by the headers. The P5 data is just a sequence of bytes; sequences of either 2 or 1...

A quick search on Google brings up
http://netpbm.sourceforge.net/doc/pgm.html

According to that, P2 is a text version, whereas P5 is a raw binary data. If you want to perform the conversion from...

If you have an integer which is four bytes long, and you do

x & 255

You are effectively stripping off the last three bytes and hence losing that data. And yes, that means that there is no way...

I'm a terrible programmer, you don't have to tell me. I was demonstrating why his error was occuring, and not re-writing his program...

tempSize=strlen(tempS);

should be

tempSize = strlen(tempS.c_str());

because strlen parameter asks for a character array, not a string object...

Use cin.get() in a loop to retrieve the characters one after the other from the user. When you are satisfied that the sentence is complete (eg. when the user type a particular character) break out of...

Global variables are a lazy programmers shortcut... As long as you don't define vast amounts of global variables you should be ok; it's not like a globally declared integer is going to cause harm

#include <iostream>
#include <vector>

using namespace std;

void main()
{
vector<char> myVector; //Create the vector
myVector.push_back('h'); //Push an item onto the back

If you want to do it your way, you don't need the header file "somefile.h", you can simply put:

extern unsigned char SomeFunc();

at the top of the file that is to use the function...

The...

int nConverted = atoi(cStr.c_str());

You needed to pass the actual string buffer and not the string object...

You won't learn by getting us to do it for you :)

Or if you want to stick to the C way of doing it, use:

strcpy(newFileText, buffer);

You will have to make sure the size of newFileText is large enough to hold whats in buffer....

Yeah I should have stated that. The problem was because strtok doesn't like const char* as a search string since it modifies it.

Thanks anyway tho

I'm getting some very strange behaviour with strtok. I have a function containing this code:



char* token = strtok(strFilter, " ,"); //Tokenize the filter string (comma separated list)

You need:

EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_wndToolBar);

This tells the dialog that it's to handle docking toolbars. Just setting the toolbar to be dockable isn't enough.

Bobwilson has posted some pretty decent stuff, helping a lot of people out. Just because he's said one "naughty" word doesn't make him all big and bad!

The point of these forums is to help people...

int nBytes;
while(nBytes = File->Read(pszBuffer, 512))
{
//Do something with the buffer here
}

That will read in 512 characters at a time. Read returns the amount of bytes read, so will...

char x = 4;
int y = (int) x;


Should work.

Call ShowWindow(SW_HIDE) on all toolbars. Then when you want to make them visible, ShowWindow(SW_SHOW).

//Hide the toolbar
m_ToolBar.ShowWindow(SW_HIDE);
//..
//Re-show it...
