Hi,
can you show me how to process NM_CLICK message with sample, this is my idea too but dont know how to do this   
Do you mean this message that is from the msdn:
<br />
lResult = SendMessage(
(HWND) hWndControl,
(UINT) WM_NOTIFY,
(WPARAM) wParam,
(LPARAM) lParam
); <br />
regards

Yes, WM_NOTIFY/NM_CLICK is sent when the tab selection is changed. You can set a function to pick it up by adding
ON_NOTIFY(NM_CLICK, <tab control="" id="">, <function name="">)
to the message map.
Where your function is defined as -
void <class>::<function name="">(NMHDR* pNMHdr, LRESULT* pResult)

That's the one that will work. I've used it in my code successfully. However, I don't think it will fire your TCN_SELCHANGE handler - you'll need to do that yourself.
The structure I've used in the past is something like this:
MyDlg::OnTabChangedHandler(arguments)
{
ChangeTab(tab.GetCurSel());
}
void MyDlg::ChangeTab(int tab)
{
Do stuff
tab.SetCurSel(tab);
}
MyDlg::SomeButtonClickedHandler()
{
ChangeTab(0);
}
so - move the 'on tab changed' actions to a separate routine that you can call from other places.

I suppose you must be creating dialogs on each of the tab pages to place your controls.
If that is the case then use the following code to programatically switch to a tab page: ( else just let me know more details. )
void CMyDialog::ShowPage( int nPage )
{
//you need to hide the current dialog.
m_dlgArray[m_tabCurrent]->ShowWindow(SW_HIDE);
//switch the tab.
m_cTabAll.SetCurFocus(nPage);
m_cTabAll.SetCurSel(nPage);
//show the new dialog.
m_dlgArray[nPage]->ShowWindow(SW_SHOW);
m_dlgArray[nPage]->SetFocus();
}

SHBrowseForFolder Function may help you...
You need to google first, if you have "It's urgent please" mentioned in your question.

For lack of a better response, your question really makes no sense. If you want to access a file in the current directory, use ".\\somefile" notation. If you want to access a file in the parent directory, use "..\\somefile" notation. If you want to access a file in a subdirectory of the current directory, use ".\\subdir\\somefile" notation.
If that's not what you're after, blame it on my lack of understanding your request.

Thanks is advance

i got solution from msdn.

Hello Davitor,
You can use function - PathFileExists()[^].
Regards,
Jijo.

Also look at GetFileAttributes() (Which I used just yesterday!)
(One problem with FileExists() is that it returns true for both files and directories.)

hi every one
I create a static library with visual c++ 6.0 App wizard.
I create a new generic class and declared my variables in its header file.
Then I initialized my variables in class constructor.
I want to use it in a new dialog based project, so I add related header file and write my library name in linker tab at project setting.
I create one object of this class in my function, But at the end of function when application exits from function occurs an exception.
I can't handle this exception.
Note : when I comment initialized this exception don’t happen.
Please help me

i correct it ,but its not my problem.

Looks like good advice...

Shouldn't cause an accvio, though - you can delete NULL in C++.

but will result in a memory leak.

I didn't say it wouldn't - I was just saying that fixing it wouldn't solve the OP's problem.

Yes, but Carlo just indicated one of flaws in the OP's code. I agree that it wouldn't solve 'the problem' of the OP, but it might (hopefully) prevent the OP from shooting his own face sometime in the future.

i havent any problem with new delete , occur exception even this case
void CUseTestLibDlg::OnBinitlib2()
{
CTest pcTest;
}
|

The problem's obviously in CTest's destructor. The only significant activity in CTest's destructor will be calls to m_str1's and m_str2's destructors. Therefore, the access violation is happening somewhere in there.
I suspect there's something not quite right with your project settings - check that the library and main app are using hte same MFC and C run-time library settings.

I have just started at a new job. Here we are new to using JNI ( for bridging C++ / Java ). I am new to JNI so please forgive my noobness
In our (win32) Java app we are loading a C++ DLL. On the Java side we have several instances of "SomeJClass" each of these instances needs access to corresponding instance of "SomeCClass" on the DLL side. The DLL exposes entry-points such as GlobalDoSomethingInC(). Here I must call the instance method of Doer::DoSomethingInC(). So I need a smooth way to map the respective this-pointers. I also need to do the same mapping when a DLL thread discovers something interesting that it needs to notify the corresponding Java-instance of.
I can think of several solutions, but I do not like them too much. My question is, is there a better way than this ?
1 Java calls C:GetNewInstance(). This returns an int that is actually a pointer to the new C instance. Java stores it in m_myCInstance. Then Java calls GlobalDoSomethingInC(), and 1a
void GlobalDoSomethingInC()<br />
{<br />
jobj tmpJ = NewGlobalRef( env, obj );<br />
Doer* myDoer = <reinterpret_cast>( Doer )tmpJ->GetMyCInstance();<br />
myDoer->DoSomething();<br />
DeleteGlobalRef( env, tmpJ );<br />
}<br />
</reinterpret_cast>
1b or:
Doer* myDoer = <reinterpret_cast>( Doer )instanceParam->DoSomethingInC();<br />
<br />
</reinterpret_cast>2 For calling from C to Java, things look, maybe, better
In the constructor C calls back into Java and stores
the Java instance reference
in a member variable. m_myJInstance.<br />
In all subsequent calls m_myJInstance can be used to call back Java.<br />
In the destructor we need to call DeleteGlobalRef( env, m_myJInstance );<br />
Not too bad I suppose. But it really safe to store the jobject reference. I mean: What happens when the GC moves the object around?
3 Our present solution does "work". But it belongs on rather on http://www.codinghorror.com/blog/
Another question, for JNI experts only. How much juice does it cost to do this sequence:
<br />
jobj tmpJ = NewGlobalRef( env, obj );<br />
tmpJ->GetMyCInstance();<br />
DeleteGlobalRef( env, tmpJ );
Thanks
Adam
