I want to post message from this dialog to another class which is alos part of the same application. Say When I click a button,this dialog posts a message to another class. How should I achieve this? how should I know about the class recieve that particular message? Pls guide me with sample code. Regards YKUT Re: PostMessage Shay Harel5-May-04 4:42 Shay Harel 5-May-04 4:42  put that in the first dialog const unsigned int wm_uiImportDone=RegisterWindowMessage("Import_Done"); give wm_uiImportDone as a pointer to the class on the class, mae sure to add that to the message map ON_REGISTERED_MESSAGE(wm_uiImportDone, OnImportDone) then on the dialog, use: ::PostMessage (m_hWnd, wm_uiImportDone, 0, 0); when m_hwnd is a pointer to the class that has to be derived from a window to get a message Updating Dialog from a thread Shay Harel5-May-04 4:23 Shay Harel 5-May-04 4:23  Hi, Let's say I have a CStatic control that is represented by a CString (m_str_status) which I pass to a working thread. I want the thread to change this status while it works, and of course show it on the dialog.... THE PROBLEM IS --->Even if I pass a pointer to the dialog to the thread, UpdateData function is illegal and will cause an exception. How do I force the dialog to update itself after I changed the value of the status string ? Shay Re: Updating Dialog from a thread jmkhael5-May-04 4:43 jmkhael 5-May-04 4:43  Several options 1. Send a message to the dialog 2. Call a function of the dialog that takes the new string and update it 3. Signal an event ...

It's not a bug, it's an undocumented feature. suhredayan@omniquad.com messenger :suhredayan@hotmail.com Re: Updating Dialog from a thread RChin5-May-04 4:55 RChin 5-May-04 4:55  One of the precautionary don'ts that get repeated when it comes to multi-threaded programming is never, ever, directly interact with a control using another thread. This nice introductory article explains this[^]. Personally, if I need visual updates via a separate thread, I would post user-defined window messages to the displaying dialog.

I have one doubt on dll loading. if two or more different applications use a same dll. how many instance of the dll will be loaded in memory. My Question is whether each application will has its own instance of the dll. or just one instance of the dll will be loaded and all applications have its mapping to the single instance. please clarfy me. thankyou in advance Mohamed Hasan S Re: How many times DLL loaded for different Application? John M. Drescher5-May-04 3:18 John M. Drescher 5-May-04 3:18  The code will have one instance but data will have one instance for each appliction that is using the dll. You can use a shared data segment to share data between processes if you want, in this case this data will only have one instance.

I dont know any forums which give programming support for this protocol and hope somebody here helps me in it... Back to my question, I wanted to automate the data sending process and so I have a loop in my thread with a waitforsingleobject function . whenever new data arrives the object is signaled and data is thus transfered.I have a problem here The data is not transferred as such, but when I include a Afxmessagebox somewhere inside the loop.It works perfectly ok. I had to quit the box everytime. what difference does the AfxMessagebox does ? I dont understand it.Can anyone help me in it? Thanks. Deepak Samuel Re: DDE problem with afxmessagebox jmkhael5-May-04 2:46 jmkhael 5-May-04 2:46  Maybe the message box is giving somewhat a Sleep equivalent and is permitting the arrival of the data to the other system? I suspect its a timing issue Papa while (TRUE) Papa.WillLove ( Bebe ) ; Re: DDE problem with afxmessagebox Deepak Samuel5-May-04 2:52 Deepak Samuel 5-May-04 2:52  Hi, Thanks for the reply. I even tried introducing a sleep in the loop instead of the AfxMessageBox but it didnt work that way. CCriticalSection question oferbgu5-May-04 1:42 oferbgu 5-May-04 1:42  Hello, I have a little question regarding CriticalSection: I have a resource that is protected by a CCriticalSection variable. let's say that the CriticalSection variable has an owner. Now, another thread is trying to access the resource, and as expected - locked. My question is: if an additional event took place, and as a result, the locked thread needs to exit the waiting, and perform some other activities (not related to the locked resource), how can I exit the attempted lock? Is it possible? Thanks... He didn't fall? Inconceivable!!!

There is a function called TryEnterCriticalSection, this should be the right choice here. Don't try it, just do it!
