I posted an article called "Multi-threaded file finder class" and they're included in the source for it. You might want to download it and check it out. By the way, the classes use Unicode, but you could easily convert them to ANSI or TCHAR if you need to. Hope it helps. Re: List of strings 31-Mar-02 0:49 31-Mar-02 0:49  Thank you all for your help ! How to take over the desktop Chris Hafey30-Mar-02 7:44 Chris Hafey 30-Mar-02 7:44  My application is designed to run with at least two monitors. The main application is full screen on the primary display and creates full screen popup windows (without captions/borders) on all secondary displays. I would like to make it so any popup windows on the secondary displays are always on top of my full screen window. That is, any other popup window (from my app or another) is always on top of it. Windows supports "topmost" windows, but it doesn't have a "bottom most" concept. I have tried to subclass the desktop window, but it doesn't work. Right now I am making all of the popup windows my application creates topmost to workaround this, but that doesn't solve the problem with popup windows from other applications.

The application actually uses all the monitors to display the images! The problem is when the user wants to run other applications at the same time such as Internet Explorer or Word. Chris Hafey MFC SDI Status Text User 988530-Mar-02 6:04 User 9885 30-Mar-02 6:04  How do I update the status text on the StatusBar? Will the process be different, if I have to do it from a worker thread? Thomas modified 29-Aug-18 21:01pm. Re: MFC SDI Status Text Philip Patrick30-Mar-02 7:21 Philip Patrick 30-Mar-02 7:21  No, process is your application which can have many threads, so same process but other thread. I'd suggest to use messages, sending a message to main window (AfxGetMainWnd()) from any location and catch it and change the text in Status bar by using SetMessageText(LPCTSTR) of your frame window.

Use PostMessage instead. The Status Bar is usually updated by CMainFrame::OnUpdateStatusBar() so you shouldn't need to do anything much from your worker thread except set the value of whatever it is you want displayed.

Yes, right, only PostMessage, though I wasn't clear by writing "send a message" But this is not a point. I didn't know about any OnUpdateStatusBar, where it is declared? I know some handlers in CHtmlView for status bar though Philip Patrick Web-site: www.saintopatrick.com "Two beer or not two beer?" Shakesbeer Need Web-based database administrator?

Sorry, you didn't actually say this. But as soon as I saw "send a message" my brain automatically converted this into SendMessage(). I made a small mistake with OnUpdateStatusBar(). It isn't an MFC function. This is what I do: BEGIN_MESSAGE_MAP(CMainFrame, CEDMDIFrameWnd) //{{AFX_MSG_MAP(CMainFrame) .... ON_UPDATE_COMMAND_UI_RANGE( ID_INS_OVR_PANE, ID_SB_LAST_PANE, OnUpdateStatusBar ) ....

I have included all the files required according to their documentation. When I compile, I get C2065 messages on all the functions that should be included in the project from the PCAnywhere modules. I have checked and rechecked and it appears all declarations are correct. Has anyone run into this and how did you fix it? Any help would be appreciated.

Modifying Menus with MDI and Multiple Views Eldon Zacek30-Mar-02 5:09 Eldon Zacek 30-Mar-02 5:09  I have a MDI project that allows the user to open and close different views. What I would like to do is have the menu change based on which views are currently open. I have read that MFC keeps a common copy of the menu for each template. Therefore changing the menu will causes all document menus to also change. So, do I have to update the menu each time a different view is active, including being sensitive to the document, or is there a trick to modifying the menus. If no trick exists, then where is the best place to do the changing of each menu. Should this be done in MDIActivate or in MainFrame? Any suggestions would be helpful. Thanks in advance.

This example is how I have been doing it. This works OK but everytime you make a change to the menu structure, you have to duplicate it for every menu resource. What I would like to do, is have the core menu resource and add the each view's unique menu's resource as needed. This desire appears to be the problem. You are no longer changing a unique menu ID but one shared by more than one view/document. If you have any other insite, please let me know. Thanks.

Wish You Were Here-Pink Floyd-1975 Re: Modifying Menus with MDI and Multiple Views Eldon Zacek30-Mar-02 11:01 Eldon Zacek 30-Mar-02 11:01  Yes, the example uses two different menus. They both have an unique resource for each menu. What I want to do is have a common resource ID for all menus and add/delete from the menu as different views are opened and closed. This is also a passage from the "C++ Users Guide" about menus and MDI applications: "Multiple MDI child windows of the same document type share menu resources. If several MDI child windows are created by the same document template, they can all use the same menu resource, saving on system resources in Windows." As you can see this presents an interesting problem. If I change the menu for one document. Those changes will be reflected in all the opened documents. This is the other problem I am trying to solve. Thanks. Eldon Zacek Czech-Mate Enterprises, LLC help with self-checking executable (CRC) SeNs30-Mar-02 4:15 SeNs 30-Mar-02 4:15  I am trying to make a win32 PE program perform a CRC check on itself when executed, and quit if the check fails. I know how to implement a CRC check, but how should I make the program read the bytes of its own executable? Is it possible to just open the exe using ReadFile or will this cause an error? Also, the program is non-MFC, so I require a solution that does not make use of MFC. Any help appreciated! Thanks. Re: help with self-checking executable (CRC) Todd Smith30-Mar-02 4:21 Todd Smith 30-Mar-02 4:21  You can open the file with shared read only access. I use a separate program to open the exe, compute the crc and then write the value to the end of the file. When the exe runs it can compute a crc of itself, minus the last few bytes of the file where the crc is stored, to make sure the file hasn't been modified.

If you are doing it to check if your program has been hacked then using a separate thread also makes it more difficult to hack. Don't do it the second the app starts, but after a while. I'd also look at using something stronger than a CRC, such as MD5.

The problem is that I want to fire event when mail issent and I want to fire event when all mails are sent. The problem is that one of my worker threads has to fire event by asking main thread to fire event. But this doesnt work that way it gives error in kernel32. What seems to be the problem and how can i solve it. I can only fire event when I dont have any thread working.

Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Re: Firing Events in multithreaded OCX Tili30-Mar-02 7:35 Tili 30-Mar-02 7:35  Well here is the deal. I pass pointer to worker thread of Control Class so they can communicate. Everything works fine untill I call the COntrols public Function to call Private Event firing function and there I get Access violation and VS shows me assembler code. I am using MFC not ATL. I just want my each thread to be able to fire event telling the container that it just sent an email. SO in your opinion what should I do to make things go right. Thanks in advance In my dream, I was dorwning my §orrow§ But my §orrow§, they learned to §wim
