How to create controls at runtime in VC++?
Is there any good article for this?

Search the class in MSDN and read Overview or Remarks sections. It describes how to create each control on the fly.

What kind of controls? Windows controls?
Using MFC or straight Win32 APIs?

Controls are windows, so they are created the same as any
other window, except they have predefined window classes.
In MFC, windows are created in two steps and destroyed in
two steps - one step for the C++ object (an object derived
from CWnd), and one step for the Windows object (the HWND).
CListBox m_MyListBox;
...
m_MyListBox.Create(WS_CHILD | WS_VISIBLE | LBS_STANDARD, CRect(10,10,100,40), this, ID_MYLISTBOXID);
My favorite reference for controls is the Control Library in MSDN[^]
The MFC docs have the MFC-specific info for the various control wrapper classes.

For each control we have a class for it like CButton,CListBox,.. you can declare a variable of that class or derived your class of it and then make runtime control.

If I correctly understand. you would like to use your VC++ code from within Matlab. Right?
A solution is to turn your VC++ code into mex files. The benefit is that this will speed up the execution within matlab.
I know there is a tool called MexWizard. Have a look at www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=1368&objectType=file
Hope that answers to your question.
regards

CTime class deals with the system time. So u can't use this class to set the system time.

That makes a whole lot of sense.

CTime has a construcor that takes an hour, minute, and second value
(as well as year, month, and day, which you can use any valid values).

Hi,
I use the following coe in my applcation.and i found memory leak in that.
MyFunction()
{
char *czval;
czVal = new char[100];
memset(czVal,0,100);
.....
.....
}
But i failed to delete the memory allocated.
I use delete [] czval in OnDestroy it shows thw error czVal undeclared identifier and also delete is used for pointer only.
Whats my mistake.
I use new operator in my local function where i have to delete that.
And also i need tutorial for this new and delete.Because i have lot og memory leaks in my applicatin.I dont know the proper usage of new and delete operator.

Make czval to global. Use delete[] czval in destructor / OnDestroy.
|
|
|
|
|
I have doubt that when this OnDestroy() get called.
Whether we can give breakpoint in OnDestroy() and check that.
Because when i ahve breakpoint in OnDestroy in my view class,the control didnot go to the breakpoint.
I dont know why?
Anu

When the application is exited, CView::OnDestroy() will be invoked. So u can place the delete statement there.
