 - Memmory dc and fonts I am new to using memory dc's. My drawtext function is drawing the wrong text type to my memdc. Text comes out bold and wrong text type. So my question is, how do I set the memory dc to the same font as my windows dc?So that the text will appear the same. My code is below. It is basically a ownerdrawn cbutton. Thx ahead of time for any help. CDC memdcRaise; TCHAR buff[MAX_PATH]; int a = GetWindowText(buff,MAX_PATH); //Get client size CRect ct; GetClientRect(&ct); CBitmap rbm; memdcRaise.CreateCompatibleDC(GetDC()); rbm.CreateCompatibleBitmap(GetDC(), ct.Width(), ct.Height()); HBITMAP oldBitmap = memdcRaise.SelectBitmap(rbm); memdcRaise.FillRect(ct,CreateSolidBrush(GetSysColor(COLOR_BTNFACE))); memdcRaise.SetBkMode(TRANSPARENT); memdcRaise.DrawText(buff,a,&ct,DT_VCENTER | DT_SINGLELINE | DT_CENTER); Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 243073

 - functionally equivalent According to Petzold: printf("The sum of %i and %i is %i", 5, 3, 5+3); and char szBuffer[100]; sprintf(szBuffer, "The sum of %i and %i is %i", 5, 3, 5+3); puts(szBuffer); are functionally equivalent. Consider this small c program: /* lines3.c */ void main(void){ int x, y; char szBuffer[100]; for (y =3D 1; y < 24; y++){ for (x =3D 1; x < 24; x++) if ((x =3D=3D y || x =3D=3D 24 - y) && y !=3D 12){ // sprintf(szBuffer, "\xDB"); printf("\xDB"); // puts(szBuffer); } else printf("\xB0"); printf("\n"); } return; } This is a command console application which makes a design when run. cl = lines3.c should get the executable. But if we uncomment the sprintf and puts statements and comment out the = accompanying printf the result is very different. So that tells me they are not functionally equivalent. What's the = trouble here? --=20 George Hester _________________________________ Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 243069

 - Reading Pipe & Log Hi, I'm looking for some idea of using a listbox instead of a textbox to log.

 - possible unnamed temporary problem? Hi, I have code that goes something like LNstring s = LNstring::convert(i) + ":" + LNTableMsg(vect[i]).toStr() + LNLog::getMsgFieldSeparator(); and causes a crash. Stepping it through the debugger I noticed that the statements are executed in the following order: 1) LNLog::getMsgFieldSeparator() 2) LNTableMsg::LNTableMsg(vect[i]) 3) LNstring::convert(i) Crash!!! I was wondering if there is a possible compiler issue here with MSVC's handling of unnamed variable LNTableMsg (hence .toStr() was never called) Any info is appreciated! thanks, max Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 243039

 - Problems with printf() and globals in multi-threaded app? I hope someone can point me in the right direction. I'm having problems with a console app I'm writing in MSVC using multiple threads. I assume that there is a setting I need to enable, function I need to call or some struct I need to initialize to get around these problems which seem somewhat related (accesses to global resources). Before someone suggests it, I've got the build settings setup for multi-threaded libs (MT d) Application description: The app is a simulation of another (embedded) OS and starts by setting the base thread, main(), the highest priority (THREAD_PRIORITY_TIME_CRITICAL) it then does a _beginthreadex(), CREATE_SUSPENDED, to create three child tasks setting their priority to THREAD_PRIORITY_LOWEST. The main() thread is used to control which one of the three other threads is currently running. It does this by doing a SuspendThread() on the current child thread that is running and a ResumeThread() on the thread to run followed by a Sleep(1) on the main() thread. When main() wakes up it decides which of the three to run and goes through the process again. The main() thread does nothing else except debug printf(). The three spawned threads make a lot of calls to printf() and access application globals. The spawned threads have no local variables. The problem(s): The printf() calls by the child threads, there's a LOT of them, seem to be locking up the application. They will run for a little while (a couple dozen printf() calls, then freeze. If I step the code in debug the problem goes away. If I disable the printf() calls, the problem goes away. If I have the child threads use sprintf() and route the results through the main() letting the main() thread handle all printing they run fine. The threads also seem to be having problems with accessing global memory in the order they are told to access it. A variable will have the same data that was read last time the thread ran even though another thread has modified the variable. I'm using 'volatile' qualifiers on all globals so that isn't the problem. I've seen this happen when stepping through the code in debug. As an example, thread #2 will set a variable and wait (watchdog counter method) for another thread to change it. Thread #3 changes it and when thread #2 runs again it still doesn't see the change. If anyone has any idea what I'm missing, it would be greatly appreciated! Grant Killey Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 243032

 - Typecasting without the correct constructor Hi there, I'm having problems typecasting an object in C++. What I have is several classes derived from 1 base class but the derived classes implement their own unique constructors. I only have references to the base class and at the moment I am having problems trying to call a method of the derived class via type casting as the constructors do not match. Is this not possible to do in C++? Or do I have to make solid references to the child classes from the beginning?

 - Terminating processes My application, A say, lunches another one, B, - written somewhere else by someone else and of which I know nothing about the source code. B puts up a window showing some information. I do this with CreateProcess, and I would need my program to be able to shut B down again under various circumstances. One way of doing this appears to be with TerminateProcess (using the process handle I get back from CreateProcess). But the documentation warns me that this is a draconian operation only to be used in dire emergencies. Is there a better way?

 - Side-by-Side Assembles on XP -using mainfest for COM components Hi We have an App with COM dlls. I want to run old and new version of this App which contains different COM dll versions. I was curious if anyone has attempted Side-by-Side Assemblies on XP using a manifest??? I have a couple questions 1)Is this correct - There is a Application manifest for the EXE that lists all the dll's I want to use different versions of ?? If my App uses foo.dll and mydll.dll and foo.dll is the only one that may have multiple versions - this is the only dll that needs to be in the Application manifest??? 2)Every COM dll that I want to have multiple versions on the machine - I need to create an assemble manifest for that COM dll and the dlll will also be listed in the Application manifest??? Where do the assemble manifest get stored??? How does windows find them to read??? 3)The old and new app would have different versions of COM dlls. If I have a COM dll foo1.dll and that #imports of COM dlls foo2.dll and foo3.dll - do I list all 3 dll in the application manifest??? Do I need 1 assemble manifest for each dll??? 4)Do I need to list only the dll's that I know will be different between the 2 Apps??? If I need msado015.dll but it doesn't matter what version - do I need to list in application manifest?? Any other helpful tips ???

 - Explicitly calling constructors/destructors Suppose you have a memory pointer to some allocated memory and a class. How can you call the constructor of the class so that it operates on your memory? The same question goes for the destructor.

 - new and delete operators for a class.. I want to add a new operator for one of my classes, that looks like this: void* operator new(size_t Size, void* tag); What should look like the delete operator? If I use something like this: void operator delete(void* Buffer, void* tag) it will not be called when I "delete" a class instance. If I use a delete operator like this: void operator delete(void* Buffer) It will be called, but I will get a complie warning because it's not matching my new operator. So, what is the right delete operator? Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 243001

 - Buffer Overrun Hi, I'm working on a Direct3D Project. This might not relevant though but part of it has a DirectInput routine. The d3d app launches and exception throws at me saying that buffer is overrun and the app must be terminated. What most likely be the cause of buffer overruns? Thanks PS: I have to cross-post as this is a hybrid question Jack Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 242966

 - redrawing in control with Invalidate() I have a CStatic which displays a plot - X, Y axes, tickmarks, etc. I want to change scaling of the plot by entering new ranges of X and Y. I call an overriden OnPaint for that: CPlot::OnPaint() { this->Invalidate() CPaintDC dc(this); ... draw lines and labeles DeleteDC(dc); } The problem is that it gets redrawn on top of the prevous drawing, w/o first erasing the prevous drawing. I also tried InvalidateRec() w/o success. I guess I can fill the whole area with a background color, but this seems lame. A search of this group showed that Invalidate should work, but it doesn't! What's the solution then? BTW... is there a quota of how many questions per day one can ask here? :) I wonder if I am abusing this group.

 - Assertion error when using Free (non-local pointer) Hi all, my application uses callback function in DLL (Written in C), The DLL sniff's the network card and then allocates new data dynamically using malloc() function , Then the data (pointer) passed to the host application (MFC), After I use the data and copying it, I'm trying to free the space using Free() But I get an Assertion error, After running step by step inside MS code I see that free() function check's if the new memory was allocated inside the current app (local) , if the memory wasn't allocated inside then Assertion error occur . How do I free memory from other application? [DLL] | | | | [App] steps : 1.. Application init the DLL and run it, the DLL now runs separately from the app . 2.. when ever the DLL find network data , it will allocate memory space ,and process incoming data 3.. Then it will notify the application using callback function, and pass the application a pointer to the new allocated space. 4.. the application uses the memory 5.. Application try to free the memory using the free function - Assertion Error !!!!! Env : Vs.net IDE (NO DotNet involved , pure c/c++ code .)

 - Run-time stack frame checks - false alarm? I get a run-time check failure message, saying: "Run-Time Check Failure #2 - Stack aroung the variable ... was corrupted." 1. I'm almost sure that my stack is not corrupted! 2. When I copy the func to another file, rename the copy, and call the copy instead, the run-time check message does not show. My question is: when such a message appears, does this necessarily mean that there is a problem with the source or this may be a false alarm?

 - Multiple compiler errors - this could hurt your eyes... sources : private, but very awesomely ass-huge sources. bug : I'm compiling, and on many occasions, the compilation dies with this. it ALWAYS dies this way, i think. hint : always seems to crash on cxx files (c++ surely?) possible solution : move to gcc? informations : Compiler : Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 80x86 -- the one that comes with Vs .net 2003 OS : Windows XP with Multilanguage user interface (we're msdn members where I work) tree : a mix of C, C++, and rarely but sometimes fortran. UC : small P4 1.7 with 512 mb RAM. strangely, all seemed to compile propely with the VC++ 6.0 compiler. Some people tell me it's just that .net plain s***s. While i'm more of the GNU/F_OSS breed and tend to have these type of opinions, this time i don't have them, as i am slowly having respect for microsoft. so, did VC .net 2003 break the compiler? if so, does VC Whidbey un-break it?

 - LNK4003: invalid library format -- why? I'm trying to compile and link a simple program which uses a third party DLL. When I try to link I get the error message "gci.dll : warning LNK4003: invalid library format; library ignored" I've run tool called Dependency Walker to take analyze the dll and it returned the information below, along with the warning: "Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module." Would this warning be enough to stop the link? Does anyone have any ideas about what the problem could be?

 - Exporting unmangled name from C DLL I'm new to the Microsoft C compiler and I'm having a problem. I'm trying to build a DLL from C source code and the compiler is exporting mangled names. I can't seem to figure out how to export unmangled names. Here's the source code for my function: __declspec(dllexport) long __stdcall TestExport(long integer) { return 0 ; } Can anyone explain how I can prevent the mangling? Do I have to use a DEF file to prevent mangling? I'm using this version of the compiler: Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 80x86 Thanks in advance.

 - re-sharing memory I am experiencing a problem where the data in a structure in shared memory is not being preserved. Process A creates the shared memory, spawns and passes the name to process B Process B opens and initialises the shared memory. All comunications between processes A and B work as expected. Process B then spawns another process (C) and passes it the name of the same shared memory. When Process C attempts to read an integer value in the shared memory, I am finding it to be set to a random large number, and not the value set by Process B. Note that I did not write Process A, nor design the structure used to share memory, I simply want to read and write values in processes B and C. Does anyone know what can cause this behaviour and how to prevent it? I am using VS.Net 7.1 WinXP.

 - Function pointers and dynamically loaded DLLs In my program, I load dynamically a DLL and I'm able to get a function pointer of type "int (__cdecl *)(void)" of any function in the DLL. If a DLL has a static class function, which calls the constructor and returns a pointer to the constructed instance of the class, then I don't have any problems. However, if a DLL doesn't have such static function, then I can't get it working. I'm able to get a function pointer to the class constructor, but I have no idea how to call the constructor in the way that that it also creates instance of the class (with 'operator new' obviously). Calling just the constructor, of course, doesn't return a valid instance of the class. The header of the DLL is basically like this: class dllclass { public: __declspec(dllexport) virtual ~dllclass(); __declspec(dllexport) dllclass(); __declspec(dllexport) virtual void dosomething1(); __declspec(dllexport) virtual void dosomething2(); __declspec(dllexport) virtual void dosomething3(); }; I cannot change the DLL, so that kind of workaround isn't possible. Any suggestions? Is it even possible? Thanks in advance. PS. I originally posted this to comp.lang.c++, but was asked to post it to this newsgroup instead since it'll require some compiler specific code to work.

 - sendto() return WSAEINTR Hi all, Sorry that maybe I should not post it here, but it seems that HERE there are the experts. I wrote a program, which receive data from USB and then call sendto() to send the data to this machine's own network port, and then a download application will handle the packets. On one machine this program works well, but on many other machines, sendto() just return WSAEINTR. With this return value, I have no idea how to modify my program or do sth else to solve the problem. I did not get a good answer from MSDN about WSAEINTR. Anyone know the solution? Thank you in advance.

I created a simple dialog (my dialog class is BlobeyDlg) based program as a matter of fact I haven't added anything to it except the following code for when the user clicks on the ok button: GLInterface a; a.dostuff(); and of course I have added #include "GLInterface.h" at the top now in GLInterface.h I have: #include "someincludes.h" GLInterface { ... private: static GLInterface* inst; ... }; GLInterface * GLInterface::inst = 0; I get an error during the linking phase of the build: Blobey error LNK2005: "private: static class GLInterface * GLInterface::inst" (?inst@GLInterface@@0PAV1@A) already defined in BlobeyDlg.obj Blobey fatal error LNK1169: one or more multiply defined symbols found I have never added my own structure to a program in this environment before and I think its pretty clear I'm not integrating something correctly. Any ideas? Thanks, George Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 242843

 - Strange unresolved external I have a WTL MDI application. I have a template class I am using as a base class for all docking windows. Any window I have that needs to be docked is derived from this template class: // Base docking window template class template <class TThisWnd, class TImplWnd, class TWndTraits> class WBaseDockingWnd : public CWindowImpl<WBaseDockingWnd, TImplWnd, TWndTraits> { }; // Properties window class WPropertiesWnd : public WBaseDockingWnd<WPropertiesWnd, CListViewCtrl> The problem I am having has to do with the fact that one of the member functions of WBaseDockingWnd is calling the GetSystemMetrics() Win32 API function. When the linker comes to linking the actual implementations (i.e. my properties window) it complains that GetSystemMetrics() is unresolved, even though it managed to resolve it just fine for the other places where I am using it. I turned on the /VERBOSE option for the linker and this is what it is telling me: // Found it fine when I used it in MainFrame.cpp Found __imp__GetSystemMetrics@4 Referenced in MainFrame.obj Loaded user32.lib(USER32.dll) // Error in PropertiesWnd.cpp PropertiesWnd.obj : error LNK2001: unresolved external symbol _xGetSystemMetrics@4 I noticed that the mangled names don't match in the two references. I don't know if that makes any difference though. When I call GetSystemMetrics() from within my base docking window class I do qualify it with the global scope operator (e.g. ::GetSystemMetrics()) so it should be resolving to the correct function. I don't have any function I have implemented with the same name. Any one know what is going on here? Thanks Tag: How to integrate an MFC 7.0 DLL into a standard C++ application Tag: 242842

 - it's posibile ? Hello everyone, I have the following problem: I have a class, rc and a member function witch use EnumChildWindows(hWnd, Paint, (LPARAM)&p); Paint must be 'WNDENUMPROC lpEnumFunc' and can'not be member of the class. Please tell me i'm wrong. The problem is Paint, must set also some private members of the class rc, and .. this is the problem.. because is not member .. I will write some code (i guess is easy to undestand) class rc { private: int x; public: function1(); friend BOOL CALLBACK paint(HWND hwChild,LPARAM lParam); } rc::function1() { .... EnumChildWindows(hWnd, Paint, (LPARAM)&p); } BOOL CALLBACK Paint(HWND hwChild,LPARAM lParam) { //must set somehow x.... } it's posibile ?

Hi
How to integrate an MFC 7.0 DLL into a standard C++ application.

I'm going to use an OPC Toolkit for C++ and have to interface my MFC DLLs.
How do I do this?
Any recommendations? Links?

Regards
Kjell Arne Johansen
