is it different to put the function in different place?

Hi all ,
I have written a program ,I want to realize the two different functions in respective Menu lists in MFC.one menu is "Init" to initiate the instrument ,the other is "zernike" to calculate something .
there is nothing wrong after compiling , but the result is different when I put the code in the two menu response functions. in fact if I put them in either "oninit()"or "onzernike()", I can get the result I want , but then the two different functions mixed together.if I put the corresponding part of the code in each responding function . nothing is wrong with compiling. but the result is strange when execute .
part of the code:

Code:

---

void CTest1View::OnInit()
{
  .....
  if(err = WFS_GetMlaCount (instr.handle, &instr.mla_cnt))
                handle_errors(err);
  ....
}

void CTest1View::OnZernike()
{
  ......
  if(err = WFS_CalcBeamCentroidDia (instr.handle, &beam_centroid_x))
      handle_errors(err);
  ......
}

---

in the above code, instr is an object of a class I defined to put some variables. I define the object in C**view,public, why the result is different when the code is like this:

Code:

---

void CTest1View::OnInit()
{
  .....
  if(err = WFS_GetMlaCount (instr.handle, &instr.mla_cnt))
                handle_errors(err);
  ....
    if(err = WFS_CalcBeamCentroidDia (instr.handle, &beam_centroid_x))
      handle_errors(err);
  ......
}

1. Closing tags use slash, not a backslash. So, please, edit your OP.

2. Where and how did you define the instr object?

3. What are all the other parameters you are passing in the WFS_CalcBeamCentroidDia and WFS_GetMlaCount functions?

4. What and how these WFS_CalcBeamCentroidDia and WFS_GetMlaCount functions do?

Hi VictorN,
1、I define the instr object in the header file of CTestView,

Code:

---

                          CVariable instr

---

mla_cnt、handle ...these variables are defined in the CVariable class, and are initiated in the constructor function.
2、other parameters such as beam_centroid_x is directly defined in the function of "oninit() "or "onzernike()"
3、instr.handle represents the ID of the instrument I am to detect. &instr.mla_cnt, &beam_centroid_x are the output of the WFS_GetMlaCount() and WFS_CalcBeamCentroidDia ()
where instr.handle is the output in the first function and is the input of the second function.

is there something wrong with the CVarialbe class I defined ? instr is defined in CTestView , I think the value of instr.handle can be used in the second function.
or is there something wrong when I define the instr object in the CTestView but I initiate the variables in the class constructor function of CVariable;
Regards

But you are using it in the CTest1View class?

sorry ，I have a typo. It is CTest1View, but this is not the problem
