    - Hooking the keyboard from IE Hi all, I have developed a BHO that installs low level keybaord hooks and CBT hooks globally whenever IE is opened.The keys that are pressed when IE is active are to be captured.I am trying to check whether the IE is active first, If it is i set a boolean flag.In the key hook proc ,if the flag is set, the keys are sent for further processing.The keyboard hooks is working fine(when checked separately), but the CBT hooks is not working properly. The IE page is taking a long time to load and after it loads, its not informing me abt whether the IE is active. The only code returns is the Window creations.Nothing else is happening. My hook proc is as follows: LRESULT CALLBACK CBTProc(int code, WPARAM wParam, LPARAM lParam) { if(code==HCBT_ACTIVATE) { GetClassName((HANDLE)wParam, text, TXTLENGTH); if (text[0]=='I' && text[1]=='E') IE_is_active=TRUE;// based on this my keyboard hooks is checked. else IE_is_active=FALSE; } return CallNextHookEx(hhookMsg, code, wParam, lParam); } Is this correct? wat am i missing in this?. thanks and regards, Hema Tag: Excel automation problem - dialog becomes visible Tag: 262628

    - CString memory allication question Hello there, I have a question on CStrings (the MFC class). When created from a character array, does the CString class free the memory of the array from which it was created automatically or does the caller have to to this? And if the later, can it be safely be done immediately after the construction of the CString? Here is an example. The question would be whether this code causes a memory leak or not. CString getSomeString() { TCHAR* test = new TCHAR[MAX_PATH]; _tcscpy(test, _T("myfile.txt")); return test; } void main() { while (true) { CString x = getSomeString(); } } Thanks in advance!

    - Can I change the toolbar icon dynamically ? Hi, I need to change icon of my toolbar dynamically. I mean as per the state of the application, i need to change the icon. Like, I have a button on toolbar for checking mails. And I also have autocheck functionality. Now, when application is checking the mails, i need to show stop icon over there (on the same place). And after finishing checking, i need to show the normal check icon at that position. Can anybody let me know how can I achieve this using MFC ??

    - char *pString question Hi folks, Easy one for the die-hard coders out there. I want to use a string in my program so I'm using a global (declared in the header file for my class) char *pString. So for example.. // In "MyClass.h" char *pString; In the .cpp file I wish to use this string i.e. assign it an intial value in the constructor such as - // In "MyClass.cpp" constructor pString = "Hello"; But, later on in the program I wish to reuse this same pointer to have different text. So for example, later on in the code I would like to make the string, for example, "Goodbye" such as - pString = "Goodbye"; Is there any harm in doing this?

    - bug: access to protected base class The following (simple, stripped down) combination of classes yields a compilation error at //1 using Visual C++ 2005 Express Edition : class A { public: typedef int type; }; class B { public: typedef A A_type; }; class C : protected B { public: using B::A_type; }; void test(C const & c) { //1 typedef C::A_type::type type; //2 typedef C::A_type a_type; typedef a_type::type type_2; } int main() { C c; test(c); } However, //2 , which is simply //1 broken up into two statements, does not yield a compilation error. Comeau compiles the code without error, and I cannot see any access-rule-violation in the code (that is, I agree with Comeau). Can anyone reproduce the bug on other versions of Visual Studio? Can anyone with a direct link to the VS-team report the bug? regards, Thomas Tag: Excel automation problem - dialog becomes visible Tag: 262600

    - LNK2005 when using using overloaded malloc/free (dlmalloc) Hi, I want to use dlmalloc in VC C++ Projekt. dlmalloc (http://g.oswego.edu/dl/html/malloc.html) is a memory pool which performs (in my case) better than using the normal heap management. The files from dlmalloc are one *.c and one *.h file. I tried simply to add these files to my projekt. I then get LNK2005 error (multiple defined symbols) in the Debug Version. It compiles and links fine in the Release Version. But in the Release I get an exception in msize.c when the runtime initializes. I also tried to put dlmalloc into an extra static lib projekt, with the same results. I have tried to get this work for days now and I am not getting any further. With gcc and g++ I can just compile dlmalloc and link it into my application. But with Visual Studio I keep getting the mentioned behaviour. Any suggestions are highly welcome :) Thanks a lot, Chris Tag: Excel automation problem - dialog becomes visible Tag: 262573

    - strcpy_s and friends Having at last upgraded to VC++2005, I am getting the usual myriad of errors and warnings one normally gets when porting a project to a new compiuler. I notice it *really* *really* wants me to use strcpy_s() etc instead of strcpy() etc. Out of curioity: I was under the impression that strcpy() was written into the tablets of stone which define the standard C-runtime library. Does strcpy_s() have a similar status or is it just a good wheeze by Microsoft to prevent them getting millions of complaints occasioned by buffer oveflows?

    - strftime crash?! Hi, I am using Microsoft Visual C++ Express Edition and have observed a nasty crash happening with the "strftime" function when you pass a format string that is not recognized by it. This code for instance seems to cause it to choke: char szBuffer[41]; tm *pTime; time_t now; time( &now ); pTime = localtime( &now ); // // crrrrasshh!! note the "%q" format specifier which is not // recognized by "strftime" // size_t len = strftime( buffer, 40, "%m-%d-%y %H:%M:%S,%q", pTime ); I would have expected the function to just ignore format specifiers that it didn't know about. Is it something wrong that I am doing or is it a bug? Please help. Thanks. -- Ranju. V http://nerdworks.in/ -- Tag: Excel automation problem - dialog becomes visible Tag: 262555

    - Variable number of arguments problem Hello, I have a class, which supports rollback for certain methods. Calls to these methods have the same pattern: class X { ... bool Validate() const; void BeginChange(); void CommitChange(); void RollbackChange(); ... bool SafeCall(bool (X::*pfn)()) { bool res = false; if(Validate()) { BeginChange(); res = (this->*pfn)(); if(res) CommitChange(); else RollbackChange(); } return res; } }; My problem is with passing parameters to method of class X. I could make SafeCall function as template and overload it for 0-N parameters. However, it will be ugly and unmaintainable. I could make small template for method call only: template < typename T, typename Result, typename P1, ..., typename PN> struct Call { Result operator()( T* This, Result (T::*Pm)(P1), P1 p1) { return (This->*Pm)(p1); } ... // all overloads from P1 to P1 - PN }; But I don't know how to embed it inside X::SafeCall without changing SafeCall signature for each overload. Currently I have quite unpleasant macro to solve this. I want to get rid of it. Unfortunately, I can't use boost::tuple/std::tr1::tuple. Is there any feasible solution for my problem?

    - Slow OS response with growing project I am using Visual C++ .NET Version 7.1.3088 to construct a Solution containing multiple projects. I run on a Dell PC using XP but the source files are on a server running OS Windows Server 2003 Service Pack 1. Over the past several months, I have gradually been adding source files to the projects. Right now I have a total of 113 source files being built in. What has happened is that somewhere along the line as my project has been growing, some aspect of it is affecting the way the OS is behaving. An example: If I simply start up Visual C++ .NET for this project (ie not building or editting or anything else), and I go to some other folder on the Server using Explorer and copy a small file (about 2 KB in size, using CTRL C, CTRL V) it is now taking about 35 seconds to do the copy! And this file has nothing to do with my project. It does not look like a very slow steady copy, it looks like something is blocking the command and then finally it does the copy. In this dead time, no controls in Visual C++ .NET respond to inputs either. If I shut down Visual C++ .NET, things are back to normal. If I load a "smaller" project, the problem does not come up. I am not sure how to quantify "smaller"; I tried deleting files out of my project to see if I could find an "edge". If I deleted enough out, the behavior went away, but I was not able to narrow it down to a specific number of files (or a specific file.) The phenomenum occurs for other users using other desktop PCs and the same server. It appears that it may not happen for other servers. Also if I operate entirely on a desktop PC, there is no problem. Does anyone have any idea what this is all about and how we can go about diagnosing the source of the problem? -- Wayne Tag: Excel automation problem - dialog becomes visible Tag: 262524

    - VC2005 and boost::shared_ptr Hello group, There seems to be a bug int the interop layer in VC2005 when dealing with certain pointer types (or values?) Here is a repro case using Boost version 1.32 and C++/CLI : using namespace System; #pragma unmanaged #include <boost/shared_ptr.hpp> boost::shared_ptr<int> ReturnAPointer() { return boost::shared_ptr<int>(); } #pragma managed int main(array<System::String ^> ^args) { boost::shared_ptr<int> ptr=ReturnAPointer(); if (ptr) { System::Console::WriteLine("integer : "+ (*ptr)); } } ReturnAPointer clearly returns a NULL smart pointer (px==0). The boolean operator for shared_ptr is : typedef T * this_type::*unspecified_bool_type; operator unspecified_bool_type() const // never throws { return px == 0? 0: &this_type::px; } Clearly, this operator should return an int** equal to 0, and indeed it does so in the native layer. However, back in managed code, the return value of boolean operator - as shown by Visual 2005 - is 0xffffffff. Therefore, the WriteLine function is called, which, of course causes an assertion in shared_ptr::operator*. The obvious workaround is to replace the test by : if (ptr.get()!=NULL) But it kind-of defeats the whole purpose of shared_ptr' boolean operator, and it may be difficult to find those cases in existing code. Before I report this to MS feedback, can anyone confirm the behaviour? Any idea on a solution? Thanks in advance Arnaud MVP - VC PS : The problem is the same whatever the specialisation of shared_ptr Tag: Excel automation problem - dialog becomes visible Tag: 262515

    - Design for SCROLLINFO ??? Hello: *This is a design question, so do not try to understand the logic of what variables are supposed to do, for this is not relevant to my question. I have the following code in the WM_SIZE handler: case WM_SIZE: cxClient = LOWORD(lParam); cyClient = HIWORD(lParam); SetRect(&rectA1,_RECTA1_xTL,_RECTA1_yTL,_RECTA1_xRB,_RECTA1_yRB); si.cbSize = sizeof(si); si.fMask = SIF_RANGE | SIF_PAGE; si.nMin = iMinLines; si.nMax = ((iMaxLines-1)-_pdmTOTALOFLIMITS); si.nPage = ((_RECTA1_yRB - _RECTA1_yTL)/cyChar); SetScrollInfo(hwnd,SB_VERT,&si,TRUE); return 0; However, in my WM_COMMAND handler, I have a switch statement with 10 case conditions, where each 'case' needs to modify the SCROLLINFO structure. So right now I am doing redundant coding as so: case WM_COMMAND: switch (LOWORD(wParam)) { case : 1 //Set new limits _pdvSTARTITEMLINES = 1; _pdvFINISHITEMLINES= 5; si.cbSize = sizeof(si); si.fMask = SIF_RANGE | SIF_PAGE; si.nMin = iMinLines; si.nMax = ((iMaxLines-1)-_pdmTOTALOFLIMITS); si.nPage = ((_RECTA1_yRB - _RECTA1_yTL)/cyChar); SetScrollInfo(hwnd,SB_VERT,&si,TRUE); break; case 2: //Set new limits _pdvSTARTITEMLINES = 10; _pdvFINISHITEMLINES= 15; si.cbSize = sizeof(si); si.fMask = SIF_RANGE | SIF_PAGE; si.nMin = iMinLines; si.nMax = ((iMaxLines-1)-_pdmTOTALOFLIMITS); si.nPage = ((_RECTA1_yRB - _RECTA1_yTL)/cyChar); SetScrollInfo(hwnd,SB_VERT,&si,TRUE); break; case 3: //Set new limits _pdvSTARTITEMLINES = 2; _pdvFINISHITEMLINES= 20; si.cbSize = sizeof(si); si.fMask = SIF_RANGE | SIF_PAGE; si.nMin = iMinLines; si.nMax = ((iMaxLines-1)-_pdmTOTALOFLIMITS); si.nPage = ((_RECTA1_yRB - _RECTA1_yTL)/cyChar); SetScrollInfo(hwnd,SB_VERT,&si,TRUE); break; and so on... anyways , you get the idea.... this repeats for 10 times! Is their another way to set the SCROLLINFO structure without re-writting the following code for every case of the switch statement: si.cbSize = sizeof(si); si.fMask = SIF_RANGE | SIF_PAGE; si.nMin = iMinLines; si.nMax = ((iMaxLines-1)-_pdmTOTALOFLIMITS); si.nPage = ((_RECTA1_yRB - _RECTA1_yTL)/cyChar); SetScrollInfo(hwnd,SB_VERT,&si,TRUE); I tried to replace the above code with a SendMessage command as so: SendMessage(hwnd,WM_SIZE,NULL,NULL); so this would rise the WM_SIZE message in the queue and therefore re-fetch the SCROLLINFO definition in WM_SIZE. However, the fact that WM_SIZE also contains the definition for cyClient and cxClient, this assigned unwanted values to these variables. So, what to do in a case like this... should I do a local function and repeat the SCROLLINFO definitions in there...or use an 'if' statement in the WM_SIZE handler to not repeat unwanted code when doing the SendMessage instance (this doesn't sound like good coding habits)... Any suggestions would help. Thanking all in advance! -- Best regards Robert Tag: Excel automation problem - dialog becomes visible Tag: 262494

    - Range checking before atol I would like to perform underflow and overflow checks before invoking the atol function. What is the correct way? The input to atol is a MFC CString. const CString input_value = "99999999999999999999999999999"; // how do I check the input_value is suitable for a long type?

    - close() on a closed file descriptor in Visual Studio 8 Hi, normally closing a closed file descriptor is not a big deal, it just returns EBADF and everybody goes on with their lives. In Visual Studio 8 it seems to throw up an assertion. I'm dealing with some code that just goes through the file descriptor table and closes them all (pretty typical thing to do in Unix world and OK thing to do on Windows... until now). Would appreciate any ideas on how to change the behaviour of close() to relax and not assert it. Is there any way to tell whether fd is open (without digging into internal data structures of CRT)?

    - user breakpoint errors? I get an error "User breakpoint called from code at 0x...." Can someone explain to me what this means? When I catch it in the debugger, I scroll back through the call stack (passing the NTDLL calls) and its at the point where I delete an object. Some how this delete is throwing an exception, but I'm not sure why. Any ideas? Below is the code segment, but its not weird. mCleanBuffer is a BYTE * that's dynamically allocated at startup. try { //XTRACED1 ("'%d' attributes IVMsg", mAttribList.GetCount()); if (! mAttribList.IsEmpty () ) mAttribList.RemoveAll(); if (mCleanMsgBuffer != NULL) { delete [] mCleanMsgBuffer; <---- exception point mCleanMsgBuffer = NULL; } } catch (...) { XTRACEW0 ("Caught exception attempting to delete message buffer"); } TIA -C Tag: Excel automation problem - dialog becomes visible Tag: 262477

    - Interpreting memory usage information I've got a memory problem that I'm trying to debug; as part of this, I occasionally check image size using Task Manager. I am seeing that "Mem Usage" is larger than "VM Size". How can this be? My understanding is that "Mem Usage" is the amount of memory actually mapped to RAM whereas "VM Size" is the total amount of memory mapped, whether to RAM or not. What am I not understanding? Thanks!

    - environment not passed to DLL I am having a problem with the environment variables after upgrading from VC6 to VC8. We have an executable which launches Java via the JNI_CreateJavaVM method in jvm.dll. Before launching the JVM we create several environment variables which the JVM uses. We are using SetEnvironmentVariable (have also tried _putenv) to set the variables in our process. Calls to GetEnvironmentVariable confirm that the variables are set properly. However, Java, launched through the dll, does not see the variables. The same exact code works if compiled with VC6. It only fails with VC8. Also, I tried creating another executable which modifies the environment variables then calls CreateProcess to start the other executable. In this case, it works and the JVM can see the environment variables. Did something change in VC8 that would cause this behavior? Tag: Excel automation problem - dialog becomes visible Tag: 262472

    - Magically appearing prototypes I've inherited a fairly complex application written using MSVC v6, which appears to rely on some odd features. It's behaviour with regard to header files and prototypes is strange. It seems often unnecessary to include a header or declare a prototype. For example the code uses "localtime", but does include time.h anywhere. Still, if the wrong number of arguments are given for localtime it gives an error. Windows.h is not included in many files, and it's functions still work. It does this with precompiled headers enabled or disabled. How is it doing this? Are prototypes being stored in a separate file somewhere? Is it possible to stop it from doing this, or at least emit warnings when missing prototypes are encountered?

    - Interesting #define #ifdef behavior Hello, I just spent an hour debugging an interesting problem involving the MS VC++ v6 compiler. Like most developers, we use #defines to trigger when certain code should be used. I found a module that simply refuses to process certain #defines and even #pragma message statements early in the source file. I'd like to know what problem I've run into and what the proper resolution needs to be. Obviously I can fix the code I'm working on. My problem comes with examining all our other code to look for similar problems. A short example follows: ===== start of sample code ===== // Uncomment the following line to use the secure servers #define USE_HTTPS_INSTEAD_OF_HTTP // NOTE: The above line is not honored and does not define the value. // NOTE: Neither of the messages appear in the compiler output. #ifdef USE_HTTPS_INSTEAD_OF_HTTP #pragma message( "Using HTTPS" ) #else #pragma message( "Using HTTP" ) #endif #include "StdAfx.h" #include "Delivery.h" #include <afxinet.h> #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif // NOTE: The following define is honored, but the one at the beginning of the file is not. // NOTE: The line was copied and not retyped. It appears to be where the #define // is located in the file. #define USE_HTTPS_INSTEAD_OF_HTTP // Much later in the source the following code appears #ifdef USE_HTTPS_INSTEAD_OF_HTTP printf ("Using HTTPS Connection\n"); CHttpConnection *HTTPConnection = InternetSession.GetHttpConnection (ServerList.GetAt (ServerIndex), HTTPS_FLAGS, HTTPS_PORT); #else printf ("Using HTTP Connection\n"); CHttpConnection *HTTPConnection = InternetSession.GetHttpConnection (ServerList.GetAt (ServerIndex), HTTP_FLAGS, HTTP_PORT); #endif // PROBLEM: Unless the second #define is added, the code always uses the HTTP Connection. ===== end of sample code ===== Thank you for your help, David Tag: Excel automation problem - dialog becomes visible Tag: 262450

hello,

I have a problem in my MFC class library (VS2003) w.r.t excel automation.

I open an excel file to grab some data and close it. When the user
clicks the button to open another excel file, the file that I previously
used is show in an excel window that opens... (i NEVER want excel to
be visible)

My interface to the excel automation is implimented through a singleton
object.

I think that the focus of excel (even though the visible property is
FALSE) is being propagated to the top when focus is lost on my app
(focus going to the open dialog). Trying to set breakpoints i can see
that the excel window opens before the code to launch the open dialog.

Any hints/tips would be appreciated.

Jamie

If no one responds here you can try posting again in one of the groups that
focuses on automating Office

microsoft.public.office.developer.*

On the off chance your problem is with MFC itself you can try

microsoft.public.vc.mfc
