C++ :: Boost Wave Tool Not Find Default Include Directory?
Jun 2, 2013
I have built the wave tool and now am trying to run my source code through it. But it just doesn't want to find the include directory. I just don't understand. Here's my command:
#include <stdio.h>
#include <vector>
#include <map>
#include <string>
Perhaps it how I built it since there is no info on how to do this? I just ran ../b2.exe from the boost_1_53_0/tools directory.
I'm running CYGWIN_NT-6.1-WOW64 TARDIS 1.7.18(0.263/5/3) 2013-04-19 10:39 i686 Cygwin with a g++ version of 4.5.3. g++ has no problem finding the default include directory (I don't have to specify the -I switch). The -I switch doesn't seem to work for any of the other include directories that I wan to use either, but I want this cleared up before I get into that since it might be related.

I've forgotten how to include a path to a folder from my current directory!
I mean, instead of loading my dice images as "dice6.png", I'm trying to load them from a file, as ".Imagesdice6.png"
Not sure why, but this isn't working. Google searching has got me nowhere.

There was an "impovement" since Windows 7 in algorithm for selecting the initial directory, which is described here OPENFILENAME structure. Briefly:
Windows 7:
If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory. Otherwise, if lpstrFile contains a path, that path is the initial directory.
Otherwise, if lpstrInitialDir is not NULL, it specifies the initial directory. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. Otherwise, the initial directory is the personal files directory of the current user. Otherwise, the initial directory is the Desktop folder.
The problem that this behavior is not what users of my program expect. Another constraint is that I need to use old CFileDialog dialog, not Common File Dialogs. I've tried to use advises described on StackOverflow and on MSDN. This solution by EllisMiller works perfectly:
Specifying a full path (including filename) in lpstrFile. The filename of course shows up in the filename box which is annoying. I ended up using a filename of "." and adding a bit of code to clear the filename combobox once the dialog is open.
BUT I can't figure how to clear the filename combobox. I've tried to add hook procedure, enumerate windows and clear text, but this didn't work for me. So, my question is: how can I clear text in the filename combobox of CFileDialog?

I'm doing a mixer with wave files. I can play and even apply the reverse effect to them. the logarithm is like this:
for( unsigned int i=0; i<sampleCount/2; i++ )
{
// swapping with the other half
double temp = samples[i];
samples[i] = samples[sampleCount-i-1];
samples[sampleCount-i-1] = temp;
}
Now I want to apply these effects to the files: delay, slow, and fast but I don't know how to do it. The teacher told me that to do it slow I need to double the Samples so I tried to do this samples[i] = samples[sampleCount*2]; it does not work......Also I apply the contrary to do make the sound fast samples[i] = samples[sampleCount/2]; the samething I don't get the sound desired.
For the daley part I'm thinking on play the audio one without touch it and then repit it 8 times or more to create the delay.... I did it like this:
double temp = samples[i];
samples[i] = samples[sampleCount-i-1]+ (samples[sampleCount -i-1]*8);
It didn't work..why the use of -i-1 after sampleCount!!

I have the following initial code:
Code:
double objectAngle = -90.0f;
double objectSpeed = 3.0f; // meters per second
double objectDistance = 300.0f;
double objectTime = 0.0f;
double objectHeading = 90.0f;
double elapsedTimePerCycle = 1.0f;
My coordinate system looks like this:
Code:
90 y
|
|
|
+-180 -------------------- 0 x
|
|
|
-90
I want to calculate a new x,y such that it follows a sine wave like pattern until it gets to point (0,0). I want the width of the arc to go out to about -45 degrees, and the same on the other side to about -135 degrees.
How can I compute these new x,y coordinates in C++?

I am currently working on an arcade game for my final assignment this year. I am struggling to get a sine wave movement with the saucer. Here is the code for it:
void ArcadeGame::spawnSaucer() {
Texture* pTexture = getTexture("saucertexture");
m_pSaucer = new GameObject(pTexture, "saucer");
m_pSaucer -> setPosition(1000, 300);
m_pSaucer -> setVelocity(-1, 10 * sin(1 * 3 * PI / 180), sin(1) * OBJECT_DEFAULT_SPEED);
addGameObject(m_pSaucer);
m_pSaucer->setSolid(true);
}

I have problem with this code:
Code:
#include <string>
#include <fstream>
#include <iostream>
#include <cstdlib>
using namespace std;
// multiplier
const double MULTIPLIER = 0.0000001;
[Code] .....
It should cut wav files into smaller pieces using text file .lab (the values multiplied by * 0.0000001 gives time in second. For example, i have such file with recorded yes and no: [URL] ..... and such boundaries [URL] .... It all should be in the same folder, then, after puting "yesno.wav" into command line and press enter it should gives 2 files with yes and no words. But it doesnt - i obtained one file with silent and one short sound. The record is recorded by Audacity, default sample rate 44100, default sample format 16-bit.

I need to create a sinewave. I have the values in an Excel file. The code reads the excel file and prints the values in the cmd but I need it to print back into excel as a sine wave. Pretty sure its currently values for a triangle wave but whatever I want a wave before I care about the type.
Description: Creates an array of values of a triangle wave, prints the result to the screen and creates a CSV (comma separated variable) file of data points. Allows user to enter number of amplitude and number of cycles
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#define N_SAMPLES 1000 // crashes if array size > 1000?
#define UP 1
#define DOWN 0
[Code] ....

I want to create an application that automatize different applications in the sense that my application will be able to press automatically different buttons on another application.
For example: my application will start, let's say, Microsoft Office, will press some buttons in MSOffice, and will close MSOffice.

I'm working with a game editor program, where the player can create their own maps. Right know I'm working with collisions, and since it's unpredictable where the player place the objects like trees, houses and cars...etc have I an idea with making a rectangle selection tool. Where the player can drag a collision box around the object, so the sprite stops when it hits the box. The problem is that I dont know how to make a tool like that. so my question is how do I create a tool like that (see picture under for more information)?
btw I'm using the SDL framework
here is a picture that illustrate the tool I want to create: [URL] ....

I was wondering if its possible to change the color of the anchor point in the transform tool.
Is this possible? Sometimes I'll move it and it takes forever to find it again on a dark image. The actual image of the cross hairs must live in the application contents somewhere? Or its made by script. After a quick search of "transform" I found this file.. Not exactly sure what I'm looking at inside but it appears to be c++ code? [URL] ....
SCREEN GRAB: [URL] ....
FILE: [URL] ....

I am working on a script compiler that must output compiled script into binary file. Compiling etc is not a problem. The problem is detecting some specific cases. Nothing seems to work. If it works, then it breaks as soon as i modify the script.
Here is example "script1":
Code:
1VAR1 c1 = 44
2VAR2 c2 = 66
3beginscript
4if(c1=44)
5do_nothing
[Code] ....
Second example "script2", when there can be also some command between ENDIF and ENDIF. In this case: do_nothing command.
Code:
1VAR1 c1 = 44
2VAR2 c2 = 66
3beginscript
4if(c1=44)
5do_nothing
[Code] ....
The INDEXES before each line are not in actual script. They are just to point YOU to specific lines. Although the INDEXes are in compiled script!! This is very important. As you see there can be simple IF_ENDIF and nested (more complex) IF_ENDIF.
i.e IF_ENDIF inside another IF_ENDIF.
There are also IF_ELSE_ENDIF and some other ones, but im trying to make simple IF_ENDIF work first.
ENDIF is "SPECIAL" command, the IF, DO_NOTHING are "usual" commands.
"Usual" commands must always jump over(!) the ENDIF. ALWAYS!!
They must "ignore" them!
One strong RULE is like this for usual commands: always jump over any ENDIF, not matter what. If there is one, two or more ENDIF's in a row, then just jump over them to the closest NEXT usual block command. If there is some "usual" block command between multiple ENDIFs, then jump to this command and this command must therefore check whats next command right after it. And do the same: check if next command is ENDIF, if yes, jump over it, until "usual" block command is found.
This is the place im stuck. When i some time ago thinked about some ideas, i saw some patterns. One of them was that: Seems like if its nested IF_ENDIF, then every usual block command jumps out of it, i.e. right after the final ENDIF of this current nested IF_ENDIF.
But as soon as i added do_nothing between the two ENDIFs the so called "pattern" broke. In script2 above you see index 11 is do_nothing. Ok its in nested IF_ENDIF it should jump out to command index 17. But no, because there is do_nothing between index 13 and 16. If we jump out at index 11, the command 14 would never execute. This is a BIG NO. One idea i was thinking and trying was to use STL::FIND, STL::FIND_IF to find next "usual" command after specific index. But my code seems to crash sometimes and not work always.
Code:
bool NextNonENDIF(int i) {
return (i!=98);
}
int findNextBlockCmd(vector<int>&vec, int curidx)
[Code] ....
Here i pass him the vector that contains all the command TYPES in current script. Each command has its own TYPE or better called unique ID in which way compiler knows what is what. So in this case im trying to find a command thats NOT "ENDIF", in other words im trying to find next usual command after specific type of command. Lets just say the TYPE or unique ID of do_nothing is 555, im trying to find it.
How i should continue with this? What to use maybe stl::stack, some custom command indexing, some sort of labelling for usual commands in nested IF_ENDIFs or what?
In general, look script2, and i ask: There is index 11, this guy should look if there is any usual block command left for him before the final ENDIF at index 16. If there is, jump to it. If there is none, jump out of this nested IF_ENDIF to index 17.
Question: how to do it? What algorithms to use? I can use STL, BOOST, whatever. And i can use C++11.

I'm not sure if I was some weird syntax problem or the way Ive ordered things. But a conditional statement I have created is not performing the way I want it to.
else if ( !( xDif == -1 && yDif == 1 && prevXDif == 1 && prevYDif == 0 ) )
{
foundArr[lastX][lastY] = 1;
}
When debugging, the condition was activated with the values:
xDif = -1
yDif = 1
prevXDif = -1
prevYDif = 0
However, I want the condition not to follow through as I am using the 'NOT' or '!' operator to negative the entire statement. For some reason, the line of code within the else if is still running.
