Proxy Stub Peter Liddle9-Mar-02 5:48 Peter Liddle 9-Mar-02 5:48  Hey Guys what are the advantages behind merging the proxy and the stub in a dll file and is there any need to enable MTS. In other words what do this features allow you to do i can't do in a standard dll with MFC support. Peter Re: Proxy Stub soptest9-Mar-02 13:30 soptest 9-Mar-02 13:30  COM has nothing to do with MFC at all. Proxy and stub also has nothing to do with MTS. When COM marshals and unmarshals interface it uses proxy and stub of that interface. So if proxy/stub is merged with your COM object that means no one can use it but owner. soptest MFC worker thread and message Queues Kevin Behilo9-Mar-02 5:31 Kevin Behilo 9-Mar-02 5:31  Hi, When I’m not using MFC and starting worker threads with _beginthreadex I can give them message queues by calling: PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE); and then later on in the thread use GetMessage. I can do this without a window which is pretty cool. I tried putting PeekMessage into the ThreadFunc of a CWinThread derived class but it fails and, of course, the later call to GetMessage causes the program to hang. Before I start pounding my head against the wall I figured I would ask here to see if anybody would know why this would fail and if it is possible to workaround (without creating a window and using a UI thread). Thanks, -Kevin Re: MFC worker thread and message Queues Tim Smith9-Mar-02 5:55 Tim Smith 9-Mar-02 5:55  GetMessage will hang if you don't have a message waiting. Are you using PostThreadMessage to post a message to that thread? If so, make sure you are doing that properly.

Re: MFC worker thread and message Queues Kevin Behilo9-Mar-02 6:06 Kevin Behilo 9-Mar-02 6:06  Tim, I’ve been writing server apps w/o a GUI so bear with me on my next question. Why would the GUI hang if a message queue has been created on an independent worker thread? I’m beginning to believe that a queue has not been created because the call to PeekMessage returns FALSE. -Kevin Re: MFC worker thread and message Queues Kevin Behilo9-Mar-02 6:34 Kevin Behilo 9-Mar-02 6:34  I figured out why the GUI was hanging. A mistake not related to the Message Queue. But I still can't get the Message Q to work. Is there any reason why the scheme in my first post would not work? Is the thread ID that I get from the CWinThread valid to use in: PostThreadMessage(pThread->m_nThreadID, 1,1,1); Thanks, Kevin Re: MFC worker thread and message Queues Tim Smith9-Mar-02 8:39 Tim Smith 9-Mar-02 8:39  Without more example code, I have no idea.

Re: MFC worker thread and message Queues Kevin Behilo10-Mar-02 5:14 Kevin Behilo 10-Mar-02 5:14  I gave up on trying to create a message queue in an MFC worker thread by calling PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE); There is a good article by Joseph M. Newcomer titled "Using User-Interface Threads" which describes what I wanted to do using UI Threads. I still would like to know why i can't create the message queue, though! -Kevin ShellNew / Namespace Extension :(( 9-Mar-02 5:25 9-Mar-02 5:25  I am having much trouble getting my shellnew object to appear on Explorer's right click New> menu... I have tried putting it in the Winnt\ShellNew, I have tried creating the ShellNew key (and even tried values) under my filename under HKEY_CLASSES_ROOT... There just seems to be nothing I can do to get it to work. I would appreciate ANY pointers you have, because this is crucial to my application's release. -- Chas gte761u@prism.gatech.edu Re: ShellNew / Namespace Extension :(( Michael Dunn9-Mar-02 6:35 Michael Dunn 9-Mar-02 6:35  Assuming your extension is .foo, under HKCR\.foo\ShellNew you need to create a value that tells the shell how to create new .foo files: Command Executes an application. This is a REG_SZ value specifying the path of the application to be executed. For example, you could set it to launch a wizard. Data Creates a file containing specified data. Data is a REG_BINARY value with the file's data. Data is ignored if either NullFile or FileName is specified. FileName Creates a file that is a copy of a specified file. FileName is a REG_SZ value, set to the fully qualified path of the file to be copied. NullFile Creates an empty file. NullFile is not assigned a value. If NullFile is specified, Data and FileName are ignored. --Mike-- Rollin' in my 5.0 With the rag-top down so my hair can blow.

Re: ShellNew / Namespace Extension :(( 10-Mar-02 6:07 10-Mar-02 6:07  I tried to use NullFile with no success... I tried Data too. Any other ideas? (or should I really do Command) Is there some kind of COM object in which you have to modify the context menu with InsertMenu or something? -- Chas gte761u@prism.gatech.edu Owner drawn tab controls Derek Lakin9-Mar-02 3:13 Derek Lakin 9-Mar-02 3:13  Anyone know how to increase the height of a tab header (the bit with the label and image on it). I have an override for DrawItem, but basically it just changes the font and colour. The trouble when the font is bigger than the default it gets clipped. It would be nice to work to work out the width and height (using GetTextExten32 I guess), but it's the height I want to increase specifically. Derek Lakin.

Re: Owner drawn tab controls Tomasz Sowinski9-Mar-02 4:25 Tomasz Sowinski 9-Mar-02 4:25  I'm not sure about tab control, but with owner-draw listbox you handle WM_MEASUREITEM if you want to change item height. At least give it a try. Tomasz Sowinski -- http://www.shooltz.com Problem in making a field !

For radio buttons call: CheckRadioButton Checkboxes uses: CheckDlgButton To clear the text in an edit box call: SetWindowText Re: clearing fields Nish Nishant9-Mar-02 6:52 Nish Nishant 9-Mar-02 6:52  If this is an MFC program you can do a short-cut trick. Call UpdateData(false) and assuming you have not misused UpdateData at all [which means your DDX member variables get UpdateData'd only on OK] this will reset every control back to how it was on dialog-load. Understand me?

Re: edit controls Christian Graus9-Mar-02 0:21 Christian Graus 9-Mar-02 0:21  GetWindowText, to get the text. atoi to convert it to a number. CString::Format to turn it back into a string, then insert it into the listbox. CString strNumber; MyEdit.GetWindowText(strNumber); int nNumber = atoi(strNumber); strNumber.Format("%d", ++nNumber); I forget how to insert strNumber into a listbox Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

Converting it to an int is only needed because you said to increment it. GetwindowText/SetwindowText allows you to grab and put the text in an edit box.
