Try to get the handle of child using GetWindow.
- NS -
|
|
|
|
|
if will will obtain a handle to the child window (GetWindow with GW_CHILD parameter) you can send or post a message to that window WM_CLOSE...

if you don't have a member or a pointer to the dialog, then that is the only good way i can think of...

Why are you attaching it to the this class?
You can simply call pWnd->PostMessage( WM_CLOSE );
I wonder how it is working!

If you are creating a child dialog you would be creating the pointer for that for that child dialog in Parent class.
So use hat pointer and call DestroyWindow()

i am trying to create a method in Visual studio C++ / MFC, i have been playing around with it for a few months now and never needed to create a new method to call untill now.
i tryed looking at C# to get a few ideas ( yes i know the are different )
i have looked a few places on this site and through google and still can not find what i need ..
to be exact on what i need i have a combobox that when the selectedIndex is chosen then it will call a calculation method
in C# would be like this ( i know C# better, and makes it easy for me to show an example what i am trying to do )
//Calculation Method
private void Calculation()
{
//calcuate the information
}
private void combobox_SelectedIndexChanged(Object sender, System.EventArgs, e)
{
//calling the calculation method
Calculation();
}
Thank you for your time!

Double-click on the ComboBox control on the dialog box editor, the wizard will generate you an event handler function.
And then right-click on that ComboBox control again on the dialog box editor, choose Add variable on the context menu, and the Class Wizard pops up for you to name your variable, say m_ctrlCombo for example.
Now back to the event handler,
void CMyDialog::OnMyComboClicked(...)<br />
{<br />
int iSelection = m_ctrlCombo.GetCurSel();<br />
if(CB_ERR != iSelection) {<br />
Calculation();<br />
}<br />
}

thank you for your time

I have a problem with using function poiter. My program has two parts:
part 1: mydll.dll
typedef BOOL (*SpeakFunc)(const CString s);
#define DLL_EXPORT __declspec(dllexport)
BOOL DLL_EXPORT Init(HWND hwnd,SpeakFunc func)
{
...
}
part 2: adding the mydll.lib of the part 1 into the project of the part 2
in the test.cpp file of the "Test" class
typedef BOOL (*SpeakFunc)(const CString str);
extern BOOL Init(HWND hwnd,SpeakFunc func);
BOOL CTest::Speak(const CString)
{
...
}
void CTest::TestMethod()
{
...
Init (NULL,&CTest::Speak) ; // the compiler notices an error here
...
}
The error message like below:
"error C2440: 'initializing' : cannot convert from 'int (__thiscall CTest::*)(const class CString)' to 'int (__cdecl *)(const class CString)'
There is no context in which this conversion is possible"
please help me...Thanks a lot.

In "part 1" you declare SpeakFunc as a global function but in "part 2" you attempt to pass a pointer to a member function.

Hai
How Can Run a Batch file ? as We can do with ShellExecute()/CreateProcess()/System()is there any method
so i can run a batch file .
Fly Like An Eagle With MIGHTY POWER.

system() is ok if you don't want to keep track it till the end of the tasks in the batch file.
Otherwise you had better choose other approaches.

You can run a batch file exactly like any other executable...
