I have added the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\MyProg with the param value UninstallString="RunDll32 C:\WINDOWS\DOWNLO~1\MyProg.DLL,DllUnregisterServer" But when I launch Uninstall from the control panel, I get the message : "Rundll32 has performed an illegal operation and will be shut down" I put another entry point DllUnregisterServer2 doing nothing in my DLL, but I obtained the same message ... Could someone help me on how to uninstall a dll from the control panel or what is the right syntax of an entry point called for uninstall? Thank you!!

Just another thing : Is this implicitly calls the DllUnregisterServer function? ... the problem is that I ould like to add an event while uninstalling, like a message box or a shellexecute command ... Thank you once again!;) sequential member variable name lucy27-Mar-02 9:27 lucy 27-Mar-02 9:27  Could you please tell me if there is any easy way to do this? the problem is: I have a dialog, which have 14 radio buttons and 14 edit boxes. The 14 radio buttons are grouped and have an int m_nRadio assigned to it. Each radio button has an edit box to its right, and each edit box has a CString variable associated with them, they are named as m_edit0, m_edit1, m_edit2, ..... , m_edit13. now, when user press a button on the dialog, I want to get the contents of the edit box next to the selected radio button, that is: if ( m_nRadio == 0 ), I want contents of m_edit0; if ( m_nRadio == 1 ), I want contents of m_edit1; What I can think of now is using a 14 cases switch statement, which is clumsy, and stupid. Is there any good way to do this? Thank you very much for any input! Re: sequential member variable name Tim Smith27-Mar-02 9:45 Tim Smith 27-Mar-02 9:45  Well, I can think of 2 solutions. The first would be to make your edit variables an array. But I think that would cause MFC's automated dialog junk to get very confused. Another option would be to create an array of pointers and initialize it with the address of each edit field. Then you can still use the MFC automation junk while being able to get the proper edit field using an index. There really isn't a good clean way of doing it that I know of. 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: sequential member variable name lucy27-Mar-02 10:05 lucy 27-Mar-02 10:05  Hi Tim, I tried the second option. Besides the chunk of repeated coding to initialize the array of pointers, it works like whoosh. One thing for sure is it is much better than my switch-case option. Thank you! Re: sequential member variable name Tomasz Sowinski27-Mar-02 10:34 Tomasz Sowinski 27-Mar-02 10:34  One of the options is to assign sequential control IDs to edit boxes and use GetDlgItemText(IDC_EDIT_BASE_ID + m_nRadio, strEditContent). I have no idea what kind of UI you're having, but maybe one edit would be enough? Just an idea Tomasz Sowinski -- http://www.shooltz.com - It's for protection - Protection from what? Zee Germans? Re: sequential member variable name lucy27-Mar-02 11:29 lucy 27-Mar-02 11:29  This is neat. Thank you! Re: sequential member variable name Tim Smith27-Mar-02 11:52 Tim Smith 27-Mar-02 11:52  That will work great as long as the resource IDs are sequential.

If so, it may be that you need to scanf(%u,...) to input an unsigned integer. Pass class member function as paramter?

Why do not pass pointer to that class as a parameter to foo() and inside foo() call p->DoSomething() soptest Re: Pass class member function as paramter? Jim Crafton27-Mar-02 10:50 Jim Crafton 27-Mar-02 10:50  Well if you can keep the same parameters for the function then this might work template <typename T> class FunctionPointer { typedef void (T::*FuncPtr)(int); FunctionPointer( T* src, FuncPtr func ):m_source( src ), m_func(func) {}; void doit( int x ) { (m_source->*m_func)(x) } FuncPtr m_func; T* m_source; }; template <typename T> void foo(FunctionPointer<T> fp ) { int x = 0; for (int i=0; i<10; i++) { fp.doit(x); } } MyClass::blah() { foo( FunctionPointer<MyClass>(this, DoSomething) ); } would this work ? History list in browser window Aaron Schaefer27-Mar-02 6:24 Aaron Schaefer 27-Mar-02 6:24  Hi All, I'm deriving a view class from the CHtmlView, and sticking this in a child frame window of an MDI app. Anyway, I've got a toolbar with a forward and backward arrow for going forward and backward through the CHtmlView's history list. Going forward and back is simple enough (through CHtmlView::GoForward, and CHtmlView::GoBack), but how can I determine if there are previous entries or next entries in the history list of the browser from the current page? What I need is something like a CanGoBack or a CanGoForward method so I can update the buttons on the toolbar in the CmdUI handler. Thanks, Aaron
