hey all,
say you have CSocket, or a plain WSA socket as a pointer member of a class, and you block the socket on a read method, and while it's blocked, you pass a reference to the class containing the socket to another thread through a casted pointer through the LPVOID pParam of a thread message,
THEN, you start doing other operations on the CSocket from thread 2 through the pointer, while thread 1 has the thread on the blocked receive method.
Like say thread 1 has the socket blocked receiving and thread 2 does a send on the same instance of the class with the m_pcsocket???
Does the world suddenly blow up if that happens?
I used to do this all the time with java, but I'd like to know if it will properly work before I try it with CSocket.
hey

No. I think given that a socket is blocked, you have to wait for the thread to free the socket. One solution is WSA non-blocking model. WSA modes will return immediately and allows any other threads to process the socket.

"void CancelBlockingCall( );
Remarks
Call this member function to cancel a blocking call currently in progress."
This is nuts, how are you going to cancel a blocking call if the call is blocked?
They HAVE to mean from another thread right?
Then you can cancel the receive before you send text then restart it right after your data is sent right?
am i wrong or am i right?

MFC CSockets can't be passed between threads. It should be possible with a plain WinSock socket.
|
|
|
|

It turned out I was actually looking for CSocket's OnReceive function, overriding that gave the class i was writing the desired effect.

I have a CEdit control defined like so:
EDITTEXT IDC_LOG,7,177,437,86,ES_MULTILINE | ES_AUTOVSCROLL | <br />
ES_READONLY | WS_VSCROLL<br />
I add text to it like this:
bool CFLModManagerDlg::Log(CString text, bool NewLine)<br />
{<br />
LogString += text;<br />
if(NewLine)<br />
LogString += "\r\n";<br />
UpdateData(FALSE);<br />
LogCtrl.SetSel(0,-1,FALSE);<br />
return false;<br />
}<br />
Now, no matter what I do to try to make it scroll to the bottom, it won't! What am I doing wrong?

I Got an own custom controller.
Lets call it.
class CMyCtrl , public CWnd
{
public:
// ...
//
private:
CButton m_Btn;
};
and this controller creates the CButton ( m_Btn ) inside CMyCtrl dynamically.
How can CMyCtrl know if m_Btn is clicked ??
I Can subclass CButton and overload OnLButtonUp() and to
GetParent()->SendMessage(…) but I don’t want to. There must be a way to get CMyCtrl to get the information that a child window has been click or ??

Does anyone know if it is a fact that ActiveX components such as a DataGrid on a Dialog breaks DialogBoxParam such that WM_INITDIALOG never gets called but instead immediately shuts-down (WM_DESTROY) the Dialog?
I am using code that does not use MFC. A friend says that COM (ActiveX) does NOT work in a non-MFC environment. Is there a workaround???
Thanks --

I am trying to do something simple. A user types in a share name of a resource (e.g., \\Mycomputer\MyShare), and I want to validate it to make sure the resource actually exists before going any further.
Apparently, nobody else does this, becuase the documentation for all the Microsoft networking APIs sucks, and there are very few examples on the Net (I couldn't find anything relevant). Here are some of the things I've tried to do so far:
resource.dwType = RESOURCETYPE_PRINT;
resource.lpRemoteName = uncShareName.GetBuffer(0);
size = 0;
error = ::WNetGetResourceInformation(&resource, NULL, &size, NULL);
I always get error code 487 - Invalid address. (Of course, MSDN does not list this as an error that WNetGetResourceInformation should return.)
So then, I tried seeing if I could set the NETRESOURCE's lpProvider and perhaps that would make things go smoother. But this simple code:
DWORD size = 1000;
char provider[1000];
DWORD error;
error = ::WNetGetProviderName(WNNC_NET_MSNET, provider, &size);
always returns an error 1222, network cannot be found (network not present or cannot be found). Apparently my network type is wrong, but there are no others that look anywhere near correct.
For printers, I can use EnumPrinters and get it to work - but only if the remote server is Windows NT, 2000, or XP. It gives me an error, RPC Server unavailable, if I try to look for shares on a 9X machine.
One final piece of the puzzle - I know it is not a networking issue, becuase I can see any object I want using Windows Explorer or "Run" from the Start menu.
Any help would be appreciated.

Ah, nevermind, I figured it out. The key is to use WNetEnumResources.

I am trying to find a way to display a form from a
Visual studio macro. I have opened the Macro IDE,
but cannot find a way to insert a form. Can anyone
tell me how to do this, or do I need to build an
add in for such a thing? (Coding the macro in VB)
Thanks,
NDP.

As far as I know, it's not possible in VC6. An add-in is your only option.

The story so far...
Using MSVC 6.0, I've created an MDI MFC application, and selected "Container" compound document support. I also ticked the Active Document container checkbox.
I run the application, and insert an object from a file - an existing Word document - into my document. As expected, it shows the whole Word document in the application.
I then select Print Preview from the menu. The print preview window comes up, showing an empty document. The document content is now spewing out of my printer 
So, does anyone know how to fix this so the content goes to the print preview DC, not the printer DC?
Thanks in advance

Hi,
I am trying to get XP alpha icons working in a ListView. I have created a manifest file which link to comctrl 6 but the XP style icons come out crappy. I have noticed in .NET there is a FlatStyle property that you need to set to FlatStyle.System to get it to work correctly.
How can I make XP Icons show correctly in MFC?
Thanks

I have a bunch of local MyCDlg windows that I made using: MyCDlg* pDlg = new MyCDlg that have their pointers in a stored in a vector. At some point I want to kill all these windows so I cycle through the vector and do
pVec[i]->DestroyWindow()
Right after the destroy is it okay to do "delete pVec[i];" ? Is that the way to do it?
Appreciate your help,
ns

Yes. I assume they're modeless dialogs.

That's like stopping a car by removing its key while driving. 
The proper way to force a modal dialog to end itself is to post an IDOK (or IDCANCEL) WM_COMMAND to it. That will cause the proper cleanup actions to occur. You can then delete the saved pointer to your dialog class.
