Write their own code

 CArray CPlotChartControl: : GetXSeletedIndexs (void) 
{
Double scaleX=m_rectPlot. Width ()/(m_xAxis. FMax - m_xAxis. FMin); 
Double fxL; 
Int Max=m_curSelectRect. Right; 
Int min=m_curSelectRect. Left; 
for(int i=0; i{
FxL=m_rectPlot. Left + (m_pXData [I] - m_xAxis. FMin) * scaleX; 
If (fxL> Min& & FxLM_selectPointXIndexs. Add (I); 
} 
Return m_selectPointXIndexs;

Ask god to help

I type is not int & amp;

reference 1st floor zhao4zhong1 response:

I type is not int & amp;

?? Specific how to modify??

 CPoint MaximaPoint; 
MaximaPoint. X=static_cast & lt; Int> (m_rectPlot. Left + (m_pXData [j] - m_xAxis. FMin) * scaleX); 
MaximaPoint. Y=static_cast & lt; Int> (m_rectPlot. Bottom - (m_pYData [j] - m_yAxis. FMin) * scaleY); 

if(! M_selectPointVIndex. IsEmpty ())//check if there is a repeated m_selectPointVIndex index number 
{
Bool bflags=false; 
For (int k=0; K{
If (j==m_selectPointVIndex GetAt (k)) 
Bflags=true; 
} 
If (bflags)//a repeat sequence number 
; 
The else//not repeat number 
{
M_selectPoint. Add (MaximaPoint); 
M_selectPointVIndex. Add (j); 
} 
} 
The else//selected points for the first time 
{
M_selectPoint. Add (MaximaPoint);//save extremum point coordinates 
M_selectPointVIndex. Add (j);//save extreme value point index number 
} 
Invalidate (). 
}

Others program compiled so no problem

What's the matter with your m_selectPointXIndexs defined

CodePudding user response:

 CArray -> CArray

CodePudding user response:

reference WUYUAN2011WOAINI reply: 3/f

m_selectPointXIndexs how you define the

CArray M_selectPointXIndexs;//select frequency index of X

This definition of

CodePudding user response:

 test and will not go wrong 
CArray M_selectPointXIndexs; 
For (int I=1; i <3; I++) 
{
M_selectPointXIndexs. Add (I); 
}

CodePudding user response:

refer to 6th floor WUYUAN2011WOAINI response:

 test and will not go wrong 
CArray M_selectPointXIndexs; 
For (int I=1; i <3; I++) 
{
M_selectPointXIndexs. Add (I); 
}

Headache, run before that's true, then write a function, operation have a problem, now the function is cancelled, or useless

CArray

The CArray class supports arrays that are similar to C arrays, but can dynamically The shrink and grow as necessary.

Template
At a Glance
The Header file: Afxtempl. H
Platforms:
Versions: 1.0 and later
Complete documentation: Visual c + + documentation

See Also
CArray Member Functions provides to CArray Operators, CObArray

CArray: : Add
Int the Add (ARG_TYPE newElement);
Throw (CMemoryException);

The Return Value

The index of The added element.

The Parameters

ARG_TYPE

Template parameter specifying the type of the arguments referencing elements in this array.

NewElement

The element to be added to this array.

Few

Adds a new element to the end of an array, growing the array by 1. If SetSize has had 2 with an nGrowBy value greater than 1, then extra memory may be allocated, clear that the upper bound will happens by only 1.

Example

//example for CArray: : Add
CArray PtArray;

CPoint pt (10, 20);
PtArray. Add (pt);//Element 0
PtArray. Add (CPoint (30, 40));//Element 1

CodePudding user response:

His whole into a member variable why return value I would never use it

CodePudding user response:

Return to CArray need copy constructor,
And CArray CObject based,
CObject forbidden,
Her copy constructor is private,
