Hello..
How do i import a third party libary (.lib) in Visual C++ .NET. I keep on getting the LNK2019 error during linking. I already added an entry on
Project->Properties->Linker->Advanced->Import Library = $Path\MyLib.lib..
I know this is pretty much the way to add libraries in VC++ 6...
But I still get the same error....

Ok.. sorry for this post.. I got this to work already.. I was supposed to insert the .lib file on the ... LInker->Input parameter...
sorry for the dumb question...

Hi,Everyone:
i create a project CFormView as its base class. i add "List Control" in the Mainform, and i use the "List Control" with code below:
-----------------------------------------------------------------------
class CvcydcjView : public CFormView
void CvcydcjView::OnInitialUpdate()
{
...
CListCtrl* pList = (CListCtrl*) GetDlgItem( IDC_LIST_MEM);
pList->InsertColumn(0, "TestColumn", LVCFMT_CENTER,40);
...
}
-----------------------------------------------------------------------
now i want to use the control in my other class, obviously i can't use that code to get the DlgItem, can anyone help me to solve the problem? -- use the Mainform Control in other class.
Thank you so much!

First Obtain the ptr of view class "CvcydcjView"
as
CMainFrame* pMainFrmWnd = (CMainFrame*)AfxGetMainWnd();<br />
ASSERT(pMainFrmWnd != NULL);<br />
CvcydcjView* pYourView = NULL;<br />
CWnd* pchildWnd = pMainFrmWnd->GetWindow(GW_CHILD);<br />
ASSERT(pchildWnd->GetSafeHwnd() != NULL);<br />
while(childWnd->GetSafeHwnd() != NULL)<br />
{<br />
ASSERT(childWnd->GetSafeHwnd() != NULL);<br />
if(childWnd->GetRuntimeClass()->m_lpszClassName == "CvcydcjView")<br />
{<br />
pYourView = (CvcydcjView*)childWnd;<br />
break;<br />
}<br />
childWnd = childWnd->GetWindow(GW_HWNDNEXT);<br />
}<br />
ASSERT(pYourView != NULL);
Now you have got ptr to your class you can call the functions as
CListCtrl* pList = (CListCtrl*)pYourView->GetDlgItem( IDC_LIST_MEM);<br />
pList->InsertColumn(0, "TestColumn", LVCFMT_CENTER,40);
At the moment i dont remember whether GetDlgItem() is public or not.
If its not public create your own function that should be public which calls GetDlgItem inside the class as
The below is the public function
CWnd* CvcydcjView::getItem(UINT p_nResourceID)<br />
{<br />
return GetDlgItem(p_nResourceID);<br />
}
now call this function form your other class as
CListCtrl* pList = (CListCtrl*)pYourView->getItem( IDC_LIST_MEM);<br />
pList->InsertColumn(0, "TestColumn", LVCFMT_CENTER,40);
..RR..

error C2065: 'CMainFrame' : undeclared identifier

and in my project i don't have CMainFrame Class cos it's Form based
Do you have any other suggestions?
Thx a million! (it's really lots of informations you provide!)

If you are workin on a dialog based application, the dialog is declared and created in InitInstance() of the Application class.
Why dont u declare the dlg as public in the class, instead of InitInstance().
Create and display it in InitInstance but declare it as a public variable.
Then you will be able to accessit anywhere as theApp.yourDlgVariable;
..RR..

it's a bit different.
i created the project using single document and last step choose form-base, so i do have CvcydcjApp class as well as CvcydcjDoc & CvcydcjView.
i don't know whether your method can be used in this case and how ? could you tell me the details.
Thx a million!
Best wishes!

If you are using a SDI application, then you ould definitely have a CMainframe class (the one i mentioned in my first reply).
CMainfrmae is the class derived from CFrameWnd, and without it u can cannot create a SDI application.
Check it you will have a CMainFrame class in your application and let me know.
The solution in my first reply should definitely work.
Let me know if you have a class name CMainframe (or a class derived from CFrameWnd)
..RR..

i'm so sorry! i do have CMainframe Class!
i'm so stupid! sorry!

Thx a million!!!!

Hi,Rahim:
Your code run very well in my class, thx!
now i met some problem when it's running in a thread,
<br />
DWORD WINAPI CallOut(LPVOID lp)<br />
{<br />
...<br />
CMainFrame* pMainFrmWnd = (CMainFrame*)AfxGetMainWnd();<br />
ASSERT(pMainFrmWnd != NULL);<br />
CvcydcjView* pYourView = NULL;<br />
CWnd* pchildWnd = pMainFrmWnd->GetWindow(GW_CHILD);<br />
ASSERT(pchildWnd->GetSafeHwnd() != NULL);<br />
while(pchildWnd->GetSafeHwnd() != NULL)<br />
{<br />
ASSERT(pchildWnd->GetSafeHwnd() != NULL);<br />
if(pchildWnd->GetRuntimeClass()->m_lpszClassName == "CvcydcjView")<br />
{<br />
pYourView = (CvcydcjView*)pchildWnd;<br />
break;<br />
}<br />
pchildWnd = pchildWnd->GetWindow(GW_HWNDNEXT);<br />
}<br />
ASSERT(pYourView != NULL);<br />
}<br />
when i debug, the program stopped at:
<br />
while(pchildWnd->GetSafeHwnd() != NULL);<br />
i create the thread using following code:
<br />
m_hCallthread = CreateThread(<br />
NULL,
NULL,
CallOut,
NULL,
0,
NULL
);<br />
can u give me some suggestions? Thx!

What were the values in PMainFrmWnd and pChildWnd when the program broke up.
Also tell me the how many times the while loop had processed when this problem came.
Was it a ASSERTION or an unhandled exception.
Also paste the stack trace.

yes, it's
<br />
ASSERT(pYourView != NULL);<br />
the programme can't run into
<br />
pYourView = (CvcydcjView*)pchildWnd;<br />

I dont have a clue whats the problem. But still I woudl suggest that instead of obtaning a pointer to the view in a thread and working on it. You should obtain a pointer to it before initiating the thread and pass it to the thread as a parameter. I will consider it as a much better option.

Thxs! a million,Rahim. You're so kind! so i'd love to ask you another question, your solutions are always Great!!
Rahim Rattani wrote:
before initiating the thread
i think maybe there will be some diffiulties,we initialize the thread in view class. but that's ok, i think now we can use the control using your getitem method, so coooooooool!
now i got another question,wish you can take a look:
i want to use message method, but i don't have a very clear idea about how to use it. here is the circumstance:
there is a process running in my CvcydcjView:
<br />
int CvcydcjView::ReadRecord()<br />
{<br />
OpenDatabase();<br />
CopytoMemory();<br />
SendMessages();<br />
}<br />
<br />
DWORD WINAPI CallOut(LPVOID lp);<br />
{<br />
if(ReceiveMessageFromReadRecord)<br />
DoSomething();<br />
else<br />
Wait();<br />
}<br />
i don't know how to write the code, if you can help, that will be very Great!!!!!!!! Thanks in advance!!!!!!!!!!!

Hi,Dear Rahim:
<br />
pYourView = (CvcydcjView*)pchildWnd;<br />
then i can get pYourView rightly

Can't you pass the control's pointer to the other class?
"If I don't see you in this world, I'll see you in the next one... and don't be late." ~ Jimi Hendrix

This is a really bad idea. It means the other class has knowledge about the details of the implementation of the representation, which is none of its business. This violates basic principles of object oriented programming, data abstraction, etc. Even the idea that it is a list control should be a secret from all other classes.

Anyone have any idea why when I call PostMessage in a callback function, it works just fine on W2K and WinXP, but doesn't work on Win98SE?
On all of the above O/S's, it makes it to the callback just fine, and the PostMessage() succeeds, but on Win98, it never makes it to function which handles the message.
Any ideas? Thanks!
