    - /clr option and CFileDialog Hi: I have added /clr option to my application, because I am working about the specific culture in order to be able to load the appropiate only-resource dll. But I have got a new problem, and I think is not directly related with the problem of the specific culture, else with a new problem with the using of CFileDialog. If I don´t use /clr option, my dialogs (CFileDialog) work fine, but if I put that option, when I lunch a CFileDialog, it shows files associated to my default extension, but if I selected any other extension, the files view is blank. The only way to see the associated files is changing the current folder. When I modify the folder (I go out, or I go back again to the default u other folder ) I see again files associated to the required extension. I don´t understand what is happened, because if I clean the /clr option my dialogs are fine again. Here is an example of one of my dialogs: CFileDialog *dlg = new CFileDialog(TRUE, "bmp", NULL, OFN_HIDEREADONLY|OFN_NOCHANGEDIR|OFN_EXPLORER|OFN_FILEMUSTEXIST|OFN_SHOWHELP , "MyApp Files (*.mtc)|*.mtc|Bitmap Files (*.bmp)|*.bmp|All Files (*.*)|*.*||"); Perhaps I have to change any other compiler option?

    - unicode I was wondering if anybody could advise me on unicode issues I have an application which consists of a C# program, that calls a unmanaged C++ DLL The details are as follows Environment: MSVS.NET 2k3, WinXP Pr Unmanaged C++ DLL _UNICODE defined Uses _TCHAR* for strings, and _tcs~ functions for string manipulation Uses _T("textconst") for text constants mixed debugging mode (to allow stepping into it Managed C# program Consists of one winforms control and one winforms project both have the same debug settings (allow unmanaged debugging) The DllImport interface to the C++ DLL calls it using [CharSet = CharSet.Auto and the string parameter is passed wit [MarshalAs(UnmanagedType.LPTStr)] From what it says in the documentation, it seems that by using UnmanagedType.LPTSt in the DllImport section, the operating system will decide automatically whether t marshal the string arguments as unicode or not. This is great if I just want my progra to work, but not if I want to understand what is going on with all this unicode stuff If somebody can try and understand the following questions and lend a hand t clear my understanding I'd be very grateful Will the .NET framework's interop marshal the C# calls to the DLL as unicode because the DL is unicode, or will it be because the operating system is XP On, say, a Win98 OS, which of the following are true - the DLL wouldn't compile unless unicode was turned of - the DLL would compile if unicode was kept on, but would produce garbage - the program (as compiled on XP with unicode on) wouldn't ru - the program (as compiled on XP with unicode on) would run, but characters 128-255 wouldn't be available On a computer with, say, NT/2000/XP OS, which of the following are true - the program (as compiled on XP with unicode on) would be faster than if unicode was of - the program (specifically the DLL) wouldn't be able to process characters 128-255 i unicode was turned off When I say 'if unicode was turned off' I mean the setting to switch the _UNICODE fla off correctly set in the compiler properties before compiling the DLL I notice that when I do this, sizeof(_TCHAR) = 1 and when it's on, sizeof(_TCHAR) is 2 I understand this (almost). But I'm lost when it comes to differences between different OSes And why do unicode characters take 2 bytes, when 1 - 255 can be fit in one Thank Tag: How to get text from message WM_SETTEXT, etc Tag: 229725

    - How do you use a derived CListCtrl in a dialog based MFC application? I have derived a class from CListCtrl in a dialog based app. I want to be able to use alternating colors for rows. When I use the designer, I create a ListView that I can access using GetDlgItem(the_id). If I use m_pListCtrl = (CMyListCtrl *) GetDlgItem(IDC_LIST); the constructor does not get called, and none of the overridden methods get called, because the object already has been constructed before I make the assignment. How do I get the dialog to use my CMyListCtrl when the ListView is constructed? Is it even possible to use the designer when doing this? Thanks.

    - anonymous structs and unions I tried to put an anonymous struct inside an anonymous union. Unfortunately, this does not work. With the complete code example below, I get the compiler error: error C2039: 'f1' : is not a member of 'dataElement' I can't think of any other way to define this type of structure. Basically, I want to be able to access a 32-bit integer in multiple ways, either as a full integer or broken out into bit fields, using the simplest notation possible. Actually, I'd much prefer not using an anonymous struct because these are Microsoft-specific. Anyone have any ideas? For the example below, the simplest notation would be: deTemp.f1 deTemp.f2 deTemp.dwAllData // ---------------------------- BEGIN CODE #include "stdafx.h" using namespace std; struct t_fields { unsigned __int16 f1 : 16; unsigned __int16 f2 : 16; }; class dataElement { public: union { // anonymous union unsigned __int32 dwAllData; struct t_fields; // anonymous struct }; }; int _tmain(int argc, _TCHAR* argv[]) { class dataElement deTemp; cout << "size is: " << sizeof(class dataElement) << "\n"; deTemp.f1 = 1000; return 0; } // ---------------------------- END CODE Tag: How to get text from message WM_SETTEXT, etc Tag: 229703

    - Uninitialized variables warning Hi, Though the compiler warns you of using uninitialized variables in many places, those warnings are not always shown, consider this program: #include <stdio.h> class X { public: int i; int& r; X() : r(r) // <- typo #1 { i = 27; } }; void main() { X x; int i = 28; int& r = r; // <- typo #2 printf("%d %d %d %d",x.i,x.r,i,r); } Typo #2 is detected by VC6, VC2K2, 2K3 and by the 2K5 Preview, but typo #1 is not spotted by any of these compilers, the program just crashes.

    - Why unwanted image is shown in the 1st column of CListCtrl? Hi: I'm using a CListCtrl and need to set an image for a sub-item (LVS_EX_SUBITEMIMAGES is enabled). But I noticed that as long as the SetImageList() is called, the image will show un-expectly for all items in the 1st column. When the 1st column is inserted, only lvi.mask = LVIF_TEXT | LVIF_PARAM is specified, there is no image here. Not sure what is going on. Below is the code to create the CImageList. Any thought is appreciated. // create the image list CImageList* pi = new CImageList(); pi->Create (IDB_BITMAP1, 60, 0 , RGB(255,255,255)); lc.SetImageList (pi, LVSIL_SMALL); // lc is the list control Thanks Polaris Tag: How to get text from message WM_SETTEXT, etc Tag: 229699

    - any training available on configuring VS & VC++ I'm looking to get some training in how to configure Visual Studio & Visual C++. We know C++ fairly well (migrating from a Sun environment), we don't understand configuration issues and this is becoming a stumbling block. We have an SDK that doesn't use namespaces to isolate things, we have other libraries that do have namespaces that end up with conflicts with the purchased SDK. I'm sure there are ways to resolve these issues, but they require someone who understands more of the in's and out's of configuration issues that are eluding us. We are trying to add some software engineering methodologies to this such as using CPPUnit that fail when linking with the SDK. There are things like how the syntax editor can be set to recognize non-CPP file extensions as C++ syntax and have it "stick". How a project workspace and a project work together - we have a project where the various checkboxes and menu items say "use multi-threaded library - /MT" but the PLG file shows /MD and then the compiler issues warnings about needing to use the DLL version of the libraries. I checked with Learning Tree and they tried to sell me a course on Crystal Reports, obviously there is a keyword match in there somewhere, but that probably wouldn't help much. I would like to say that we could accumulate this gradually, but we have been struggling with this for months and have made little progress. I've been following this newsgroup for the past several months, and while it's been occasionally useful, I think most of these problems are too weird for a forum such as this. -- Take care | This clown speaks for himself, his job doesn't Wayne D. | pay for this, etc. (directly anyway) Tag: How to get text from message WM_SETTEXT, etc Tag: 229648

    - InterlockedIncrement Given an instance of int, i, is the bare C++ increment/decrement operator on i atomic? int i = 0; i++; i--; I guess these operations are translated into corespondent single machine instructions. If that were the case, why would one use the Win32 routines InterlockedIncrement and InterlockedDecrement? If I were to build a COM class, is it a must to use InterlockedIncrement/InterlockedDecrement in preference to ++ and -- operators? Ben Tag: How to get text from message WM_SETTEXT, etc Tag: 229641

    - Advice on DLL parameters please Hi, I have an Excel spreadsheet that contains a VBA macro. However, this runs slowly! I have written the code in C++ which works. Currently the interface between the VBA / Excel system and the C++ program is via a file. i.e. data is exported in Excel & read into the C++ program, processed & written out to a file by C++ & them imported into Excel. I know I can use a DLL written in C++ & callable from VBA (i've already done that). I've mastered the problems of calling a DLL with an array parameter sucessfully too. My question is, is there a maximum amount of data that I can pass through a DLL call? Either a physical maximum limit, or an advisable maximum. Any advice / explanation would be greatly appreciated.

As you could see, my GTrayIcon implemented had a member variable NOTIFYICONDATA. The declaration of this member variable is dependent on the value of _WIN32_IE. In other words, the size of the structure is dependent is dependent on a preprocessor define. As luck would have it, in the file calling new, _WIN32_IE was declared as 0x0400 and the constructor implementation _WIN32_IE was declared as 0x0560. Making both of these values consistant fixed the error. Robin Tag: How to get text from message WM_SETTEXT, etc Tag: 229620

    - Access violation error - sizeof returns very different numbers for same class ? Hello, I've been trying to fix this heap memory error for about 12 hours and I'm starting to pull my hair. Can you guys help me before I go bald? Since it's a memory heap error: HEAP[WebMedia.exe]: Heap block at 003376A8 modified at 003376EC past requested size of 38 I'm having a very hard time figuring it out what exactly is causing it. I tried to remove as much code as possible while keeping the error still there. Then I tried to use "AppVerifier", "gflags", "Windbg" to understand where the error is coming from with very little success. I'm running an MFC app, in debug mode, on Windows XP Pro. The code (as minimized as possible) executed is basically this: CApplication2App::CApplication2App() { int size = sizeof(GTrayIcon); GTrayIcon *tray = new GTrayIcon(NULL, WM_MAINFRM_TRAYNOTIFY); ... ... ... } The m_tray = new GTrayIcon(m_hWnd, WM_MAINFRM_TRAYNOTIFY); is causing the crash. It doesn't even return from the new. The declaration of GTrayIcon is quite basic: class GTrayIcon { public: GTrayIcon(HWND hwnd, UINT callbackMsg); ~GTrayIcon(void); BOOL IsVisible(); void SetIcon(HICON hIcon); void SetIcon(UINT nResourceID); void SetIcon(LPCTSTR lpszResourceName); void SetToolTip(LPCTSTR lpszToolTip); BOOL Show(); BOOL Hide(); BOOL Update(); BOOL SetMenu(UINT nResourceID,UINT nDefaultPos); BOOL SetMenu(LPCTSTR lpszMenuName,UINT nDefaultPos); BOOL SetMenu(HMENU hMenu,UINT nDefaultPos); LRESULT OnTrayNotify(WPARAM wParam, LPARAM lParam); protected: private: // void OnSysCommand(UINT nID, LPARAM lParam); void TraySetMinimizeToTray(BOOL bMinimizeToTray); void OnTrayRButtonDown(CPoint pt); void OnTrayLButtonDown(CPoint pt); void OnTrayLButtonDblClk(CPoint pt); void OnTrayRButtonDblClk(CPoint pt); void OnTrayMouseMove(CPoint pt); NOTIFYICONDATA m_notifyData; bool m_bTrayIconVisible; int m_nDefaultMenuItem; bool m_bMinimizeToTray; CMenu m_mnuTrayMenu; // the window responsible for the minimization and so on HWND m_hwnd; }; The crash comes from the the CMenu constructor, I guess it is trying to overwrite a block of memory that I've messed up elsewhere, but I can't see anything what I've could possibly have done. If I move the member variables around, the crash moves around as well, it may be on 'm_hwnd' or 'm_bTrayIconInvisible', or anything. (Although it stay constant within multiple sessions). Now, I tried something interesting. Just before doing: m_tray = new GTrayIcon(m_hWnd, WM_MAINFRM_TRAYNOTIFY); I decided to check the size of the GTrayIcon class using sizeof. It returns me 112 bytes. But, if I do sizeof in the constructor of GTrayIcon, it gives me 512 bytes! From this, only 2 conclusions are possible: 1) The 'new' only allocate 112 bytes of memory, while the class really needs 512. Thus, when assigning my member variable, I end up overflowing outside of the allocate memory block. (If that's the case, why is it doing such behavior and how do I fix it?). 2) Or, it has nothing to do with it. Since the heap is already screwed up, the second 'sizeof' actually returns the good value, it's just lost somewhere and I don't see it in the debugger. Or maybe the first value is screwed up already. Anyone can provide an insight? Thanks, Robin Lavallée Tag: How to get text from message WM_SETTEXT, etc Tag: 229615

    - The Removable Storage Manager, WM_DEVICECHANGE, and other fun stuff... I'm writing a utility that needs to be aware of media (CD, DVD, Zip disk, usb stick, etc) insertions and removals. Which seems to be more of a problem than I original imagined. I can't use any auto-run features because this is actually running on Windows XP Embedded... so that's the first thing to be aware of. Using WM_DEVICECHANGE works about half the time...that is, it works when a DVD or CD is inserted, but it does not work for Zip disks, usb sticks, etc. I looked into the Removable Storage Manager, or RSM, but the descriptions for it on MSDN changes enough that I'm not 100% that it is applicable. I'd write a test application but the definition is rather deep and there seem to be some key elements missing from the documentation. So...essentially is there a sure fire way to detect insertion and removal of all types of removable media? Thanks, Ryan Tag: How to get text from message WM_SETTEXT, etc Tag: 229611

Can I build my library such that it includes those dependent libraries as one entitiy? That way this other developer will link with my library and will be done.

    - Unexpected behaviour of enums Hello, developers, the current behaviour of enumerations in both VC6 and VC7.1 (I have no VC7.0 at my hands) seems very unexpected. The following snippet enum E { e1 = static_cast<unsigned int>(-1) }; typedef bool is_positive[e1 > 0 ? 1 : -1]; does not compile successfully **with enabled language extensions** although it does so using /Za mode (which is standard-conforming). Is the behaviour in /Ze mode by design? A recent discussion in comp.lang.c++.mod seems to lead to the conclusion, that the observed behaviour should be wrong even if it is supposed to reflect C(99) rules. So even if the 'enum is actually int' rule is followed strictly, one should expect, that the expression inside enum E { e1 = static_cast<unsigned int>(-1) }; should not compile.

    - ATL/Com Properties I'm trying to create a class that I can use in VBA using ATL/Com. My question is why a Property, e.g., put_x() which is supposed to set the value of the private data element x, is not recognized as a class method when I create an instance of the class in VBA. That is, if I say Dim myObject As myClass; myObject = new myClass; myObject.put_x(3); VBA won't compile it, saying put_x is not a member function. Yet, I can say myObject.x = 3; and it works. Each of the above is a surprise to me. In the first case, put_x clearly is, as created in VC6.0 using ATL. In the second case, how is it that x can be assigned to like this when I put x in the private section of the class? What am I missing?

Hi.

I'm trying to trap WM_SETTEXT messages using system hooks and all
seems to be going well with the hooking process (i.e. I get the
messages and they correspond to the same messages I see in Spy++,) but
for the life of me I cant figure out how to get at the string: "lParam
- Pointer to a null-terminated string that is the window text." All
attempts to strlen(lParam) or strcpy(lParam) just cause havoc.

I regularly work with the .NET framework, but most of my C/C++
experience is very rusty and was very unix-centric to begin with. I'm
assuming that I'm missing something here, like having to marshal the
string across processes (the messages are being snatched from another
process) or having to envelope the whole copying affair in a critical
section or perhaps even just using different APIs than the good ol'
stdio.h stuff.

Can anyone shed any light on this for me? It seems like "getting the
text" from a message should be a fairly straightforward task.

Thanks,
Ian

The "LPARAM lParam" is of the wrong type. If LPARAM is
representing a pointer to a string then use

LPCTSTR(lParam)

(LPARAM is a way to pass a 4 byte quantity of arbitrary type which
gets round C++' strict type definition rules - you have to know what
it is and cast it.)
