Hello,
I'm finding some "smart" GDI obj(e.g. CPen, CBrush, etc.) wrapper class that implements the RAII idiom, to make the GDI coding somewhat easier. Is such stuff available?
Thanks.

I'd like to write a function that tells me how many documents I have open of a particular document type. I want to call this function whenever someone tries to open a new document and if that would exceed the predefined number allowed, notify them with a message box.
Any ideas?????
Thanks,

If you are dealing with MDI application in MFC using CMultiDocTemplate class, then I think you should use its members in this manner:
CMutiDocTemplate * t = ...;
int total_documents = 0;
POSITION pos = t->GetFirstDocPosition();
while(pos != NULL)
{
++total_documents;
pos = t->GetNextDoc(pos);
}
I hope this helps.

When you run this code you have two "test" in File last option and another after help
<br />
PROCESS_INFORMATION l_ProcessInfo;<br />
STARTUPINFO l_StartupInfo;<br />
<br />
ZeroMemory(&l_StartupInfo, sizeof(STARTUPINFO));<br />
<br />
l_StartupInfo.cb = sizeof(STARTUPINFO);<br />
l_StartupInfo.dwFlags = STARTF_USESHOWWINDOW;<br />
l_StartupInfo.wShowWindow = SW_SHOWMAXIMIZED;<br />
<br />
CreateProcess(NULL, <br />
"Notepad.exe", <br />
NULL, <br />
NULL, <br />
FALSE,<br />
DETACHED_PROCESS,<br />
NULL,<br />
NULL,<br />
&l_StartupInfo,<br />
&l_ProcessInfo);<br />
<br />
MessageBox("Wait");<br />
HWND hWnd = ::FindWindow("Notepad", NULL);
HMENU h=::GetMenu(hWnd);<br />
HMENU h2=GetSubMenu(h,0);<br />
<br />
AppendMenu(h2,MF_STRING,22,"test");<br />
AppendMenu(h,MF_STRING,22,"test");<br />

thanks alot
I didn't think it was easy like that to do what I am trying to, I thought I needed to hook the application first
I have one more question, how I can I add the WM_COMMAND ability to this code so when I click on "test" a MessaBox will pop up?
thanks in advance!

I am havin problems doing this c++ project.Its in regards to whether i can use one main class (e.g.main.cpp) or have to use a few classes.I am also a bit weak when it comes to c++ as java is my main language so any hints on the code or how to go about doing this would be great.The basic idea is :
Create a class called DataSet that stores a vector of floating-point values. Give this vector an initial size of zero, and use the push_back operation to add new elements.
The DataSet class should have a public member function for each of the operations described above, as well as a member function that adds an element to the vector.
I have to get the MEAN,MEDIAN and Standard Deviation.
I would very much appreciate if you could help me asap as I am desperately stuck.
PLEASE HELP ASAP IF U CAN
Thanks in advance,
klck2000

tell you the truth,im having a problem with everything,i dont know where to start.i just dont know how to do it,iv tried but get nothing but errors.can you help??heres my main class:
#include <iostream>
//#include "main.h"
using namespace std;
#include "main.h"
int main(){
Calcs calcs("input.dat");
cout << "Mean is " << calcs.findMeanHeight() << "\n";
cout << "Standard deviation in height is " << calcs.findStandardDeviation() << "\n";
heres my calcs class to get the mean etc:
#include <fstream>
#include <cmath>
using namespace std;
#include "calcs.h"
Calcs:: Calcs(string filename){
ifstream ifile("input.dat");
/*ifile >> _dimension;
for (int i=0; i<_dimension; i++){
for (int j=0; j<_dimension; j++)
ifile >> _heights[i][j];
}
}
void Calcs::print(ostream& s) const {
for (int i=0; i<_dimension; i++){
for (int j=0; j<_dimension; j++)
s << _heights[i][j] << " ";
s << "\n";
}
*/
}
double Calcs::findMeanHeight() const {
double runningMean=0;
for (int i=0; i<_dimension; i++)
for (int j=0; j<_dimension; j++)
runningMean+=_heights[i][j]/(pow(_dimension,2.0));
return runningMean;
}
double Calcs::findStandardDeviation() const{
// return standard deviation of heights
double squareOfMeans = pow(findMeanHeight(),2.0);
return sqrt(meanOfSquares()-squareOfMeans);
}
}
}
}
double Calcs::meanOfSquares() const{
double runningMean=0;
for (int i=0; i<_dimension; i++)
for (int j=0; j<_dimension; j++)
runningMean+=pow(_heights[i][j],2.0)/pow(_dimension,2.0);
return runningMean;
}
PLEASE HELP!!

It looks as though you have indeed started, and are well on your way.

What errors?
On a side note, you might want to update your post so that it is more readable (you'll get tons more help if folks don't have to squint their eyes and turn their head sideways to make sense of it all). Use the <pre> tags to surround the code and make sure the angle brackets are formatted correctly. The Preview button helps in this capacity.

ok sorry, im only fairly new at this.the project seems pretty basic but I just cannot do this at all.Could you give me the code or an idea on how to do this even,which would be a huge help:
Create a class called DataSet that stores a vector of floating-point values. Give this vector an initial size of zero, and use the push_back operation to add new elements
I just cannot get my head around this.From the input file I have to get the Mean,Median and standard deviation.The code I have used which I took from another c++ project I have done,is incorrect i think
thanks,
klck2000

Thanks,
I just pasted that from my project overview.By any chance would you be able to help me as I am desperate at this stage.I dont know where to start in regards to the code or what code to use??

Here is one idea:
class DataSet
{
public:
DataSet() { }
void Add( const double dHeight )
{
m_vecHeights.push_back(dHeight);
}
double Mean( void ) const { }
double Median( void ) const { }
double StdDev( void ) const { }
private:
vector<double> m_vecHeights;
};
void main( void )
{
DataSet ds;
}

thanks very much,i tried something like that lastnight though id to use floating point values so used
class DataSet
{
private:
float Vector[200]; //Holds the floating values
int Number_of_Elements; //Holds the number of elemets -1
void Sort_Vector(); //Sorts the vector to calculate the median value
public:
DataSet(); //Constructor of the class
~DataSet(); //Destructor of the class
void Add_Element(float float_value); //Add an element into the vector
float Calculate_Mean();
float Calculate_Median();
float Calculate_Standard_Deviation();
};
how do you think that looks??
thanks,
karl

One of your requirements was to use the push_back() method to add items to the vector. What you have does not satisfy that requirement.
