    - Stl map and CString trouble Hi, I'm trying to keep MFC out of this project and so I'm using the stl std::map on the heap. I was originally using a char * as the key, but I ran into the "duh, obvious -- it's comparing pointers" issue, and switched to the CString (<atlstr.h> version, NOT the CLR version) use. I thought this would solve the pointer issue since the operators for CString are overridden. Now, I declare the map as: std::map<CString, byte*>* g_VarMap; //byte is typdef'd unsigned char. also on the heap. Now, I add strings to the map and this works entirely as expected. However, later on, I try to do a find() to grab the value. Now, digging into the guts, the find() is doing an == to detect if the objects are the same. CString has overrided this operator so that it compares the guts of the strings, not the pointers. I still get find failing. Here's an example of a little dummy test. Now, as you can see here, my map has the strings in it and pointers to memory locations. - g_VarMap [5](("AA",0x003a9e0b ""),("BB",0x003a9e1b ""),("XX", 0x003a9c95 ""),("YAR",0x003a9c96 ""),("YY",0x003a9c94 "")) find returned (<Bad Ptr>,0xcdcdcdcd <Bad Ptr>) when I do a find on YAR. The code is a bit long to put here, but I'm sure this is something you know the answer to. Any ideas? To me, the == operator should return that there is a match. Tag: broken samples.... Tag: 295498

    - VS2005 Profiler generating very huge .vsp file Development Environment : Microsoft Visual Studio 2005, Version 8.0.50727.42, Microsoft Visual C++ OS : Microsoft Windows Server 2003, Service Pack 2 Hello, While profiling a project using Linker /PROFILE option, the .vsp the Report file which gets generated is about 2GB. On 1GB RAM machine the .vsp through VS 2005 IDE would not even open up; even after 2 hours. On 4GB RAM machine it opens after 30 minutes. The report did not specify the % of total time it takes (it specifies the time it take but not percentage time). What could be the reason for such a huge report file getting generated? Is there some way(some setting) to reduce the size of the profiler report so that I am able to use it? I am also keen to get the % of time consumed by the functions called during an action in the applciation, How can I achieve it? Any kind of help or pointers would be highly appreciated. Thanks and Regards Ramesh Singh Tag: broken samples.... Tag: 295487

    - Passing an array of structures from a pointer [3] Hello, First and foremost, I want to thank everyone that is helping me with my posts! Okay, so I have finally been able to enter some small C programs in VC++ so that I can test them before I actually say that they compile without errors :) The subject of this post has the same name as my two (2) previous posts which indicates that this post is a sequel to the previous posts! On that note, reccomendations have been given to me where I should not define any arrays of structures in my headers and that structures should only be declared in headers. Now ! I am trying to accomplish the seperation of my structure's declaration from its definition of arrays of structures. In other words, I am trying to declare my structure globally (or in a header) and its definition in a function. To keep the program short I did not show a header. Therefore whatever we see as glogal, it is presumed that I would include it in a header. Some questions and notes before we begin: Q1) Is setting a pointer to 0 before using it a proper thing to do? Ex: obj_DDLB = NULL; Q2) Is it proper to declare and define a structure in a header if it is only used in one place in the whole project? This means that this structure would only have one purpose for one particular .c file. Or shopuld I still just declare it in a header and define it in a function of that particular .c file. Q3) What about enums, can they be defined in a header. I do lots of that!!! Ex: enum enum_BUTT_ACTUATE { e_ACT_UD_ARWS=1, e_ACT_EXIT, e_ACT_NEXT, e_ACT_CONFIG}; Q4) This question involves a #define macro. Basically, if these types of pre-processor directives should be in a header *and* if all definitions of structures should be in a .c function, then how is one to find the size of an array structures using: //CALCULATES THE SIZE OF THE DDLB INFORMATIONS-15 #define DDLB_ITEM_LIST1 (long) ((sizeof (COLL1) / sizeof (struct ddlbColl1))) I mean if the above statement is global (in a header) and my array of structures are defined in a function, this will generate an error! I can always put the macro in the particular function where the array of structures is defined.... but would this be proper? Anyways this is not a proiority right now, but is an important consideration for me, because exactly for this problem, I put macros all over the place.... in functions in headers..... not very practical when viewing code I guess! NOTE 1) For now, please disregard the global pointers issue and why they should not be defined globally. I will look at this later. Please consider the following program bywhich compiles and obtains the correct result of 200! This is the original version where I declare and define the structure globally and then we will look at the second code sample which declares the structure in a header and defines it in a function. However the latter has a problem! ============================================ #include <stdlib.h> #include <malloc.h> typedef struct ddlbColl1{ long LINK_ID; int LIST_NUMBER; } COLL1; COLL1 DDLB_COLL1[] = {200, 4, 201, 8}; typedef struct ddListBox{ int x; long y; struct ddlbColl1 *xxx; } DDLB; DDLB *obj_DDLB; // Eventually Won't be global! DDLB* ULC_DDLB_config_ddlb (struct ddlbColl1 DDLB_COLL1[], int x, int y); void ULC_DDLB_ddlb ( DDLB *obj_DDLB); int main(void) { obj_DDLB = ULC_DDLB_config_ddlb (DDLB_COLL1, 10,5); ULC_DDLB_ddlb (obj_DDLB); return 0; } DDLB* ULC_DDLB_config_ddlb ( struct ddlbColl1 DDLB_COLL1[], int x, int y) { obj_DDLB = NULL; obj_DDLB = (DDLB*) malloc (sizeof (struct ddListBox)); obj_DDLB->x = x; obj_DDLB->y = y; obj_DDLB->xxx = DDLB_COLL1; //Assign the address of the DDLB_COLL1[] array! return obj_DDLB; } void ULC_DDLB_ddlb ( DDLB *obj_DDLB) { // implementation file which uses the infos from DDLB_COLL1 array! long x; x = obj_DDLB->xxx[0].LINK_ID; //x = 200!!! Correct result! } ================================================ Now lets consider the following code sample where I delare the structure gloabally (or in my header) and define the array of this structure in a function. This version has the wrong result for x. please view code: ============================================ #include <stdlib.h> #include <malloc.h> typedef struct ddlbColl1{ long LINK_ID; int LIST_NUMBER; } COLL1; typedef struct ddListBox{ int x; long y; struct ddlbColl1 *xxx; } DDLB; DDLB *obj_DDLB; // Eventually Won't be global! DDLB* ULC_DDLB_config_ddlb (int x, int y); void ULC_DDLB_ddlb ( DDLB *obj_DDLB); int main(void) { obj_DDLB = ULC_DDLB_config_ddlb (10,5); ULC_DDLB_ddlb (obj_DDLB); return 0; } DDLB* ULC_DDLB_config_ddlb (int x, int y) { COLL1 DDLB_COLL1[] = { 200, 4, 201, 8}; obj_DDLB = NULL; obj_DDLB = (DDLB*) malloc (sizeof (struct ddListBox)); obj_DDLB->x = x; obj_DDLB->y = y; obj_DDLB->xxx = DDLB_COLL1; //Assign the address of the DDLB_COLL1[] array! return obj_DDLB; } void ULC_DDLB_ddlb ( DDLB *obj_DDLB) { // implementation file which uses the infos from DDLB_COLL1 array! long x; x = obj_DDLB->xxx[0].LINK_ID; // x = -858993460 ????? } ================================================ All help appreciated! -- Best regards Roberto Tag: broken samples....

    - Forcedly kill console session terminates service Hi All, I have a service that is registered to a windows 2003 server SP2 with option "Allow service to interact with Desktop" enable, and the Startup type is set as Automatic. Two process was spawned by the service. The Service is running under SYSTEM account, One of the spawned process that requires COM interface object is running under an administrator C account. The other one is running under SYSTEM account. What's happening is: - administrator A logs into the w2k3 server using "mstsc / console" the service is working fine and all 3 processes are running. - administrator B logs into the w2k3 server using "mstsc / console", and administrator A's console session is killed forcedly - then COM object is destroyed, the process running in the C account is terminated, as a result the service is terminated. However, if administrator B logs into the w2k3 server after administrator A is successfully log off, the service will be working and none of the related processes will be terminated. Does any one has any idea how killing the console session forcedly by second user impacts the COM object and the service that has option "Allow service to interact with Desktop" enable?

    - Did Microsoft slightly change C++ language in 2008? The textbook for the traditional C++ class that I had in Fall of 2001 at communnity college for the Microsoft Visual C++ 6.0 C++ compiler had examples like cout << endl; that worked with Microsoft Visual C++ 6.0 In 2008 the new Microsoft Visual Studio 2008 Express Edition C++ no longer supports traditional cout by itself. Microsoft might have attempted to change the C++ programming language. On the Microsoft website they had an example similar to std::cout << std::endl Then after changing this old C++ calculator program by using a std:: before every member of the iostream class it started working.

    - Passing an array of structuresfrom a pointer? Hello, I have a two part question. I do understand the principle of an array like so: int xxx[10]; where xxx holds the address of the first item. But, when using this analogy with arrays of structures, I feel a little unsure! Anyways, here is my problem! -[Q#1]- I am trying to pass the address of an array of structures, that have already been declared in one of my headers. I don't know... but I feel like I am drawing a blank ! I know I did similar stuff like this but not from the same exact perspective and the fact that I need to pass the address of an array of strucutes somehow confuses me! Basically I need to pass the address of the array of structures to a fiunction that will then store this address in another structure for later use. Here's what I am trying to accomplish! In a header file I will be declaring several strucutures that have several members. Furthermore, an array for every one of these structures will be declared. For example, as shown below, the "ddlbColl1" structure will have an array of itself declared as "DDLB_COLL1". In my example below I only declared one (1) such strucure called "ddlbColl1", but someday I could end up having 2, 3 or even 5 of them! The thing is, that in my main calling function I want to configure all the necessary components for my drop down list box by calling the ULC_DDLB_config_ddlb ( ) function which will setup informations in the "ddListBox" structure . One of the parameters of this function will be the desired array of strucutres collections such as the DDLB_ARY[] ! Then once back in main I would call the: ULC_DDLB_ddlb (obj_DDLB); function and pass the pointer to a ddListBox structure and manipulate its data, such as the data from the DDLB_COLL1 array within the function's implementation code. -[Q#2]- When I am in the void ULC_DDLB_ddlb () function, will I be able to reference data from the DDLB_COLL1 array? I believe that to retreive or modify the data in the DDLB_COLL1 array I can do it like this: right? DDLB_COLL1[1]. LIST_NUMBER; I could be wrong, this is the first time I am passing arrays around this way!!!! Here's the code sample, I really am unsure of the lines flagged with "[***]" !!! All help is appreciated! ============================================== typedef struct ddListBox{ int x; long y; struct ddlbColl1 DDLB_ARY[]; //Store address of DDLB_COLL1 here ! [***] } DDLB; DDLB *obj_DDLB; struct ddlbColl1{ long LINK_ID; int LIST_NUMBER; } DDLB_COLL1[] = { 200, 4, 201, 8}; DDLB* ULC_DDLB_config_ddlb ( struct ddlbColl1 DDLB_ARY[], int x, int y) { obj_DDLB = NULL; obj_DDLB = (DDLB*) malloc (sizeof (struct ddListBox)); obj_DDLB->x = x; obj_DDLB->y = y; obj_DDLB->DDLB_ARRAY = DDLB_ARY; //Store address of DDLB_COLL1 ! [***] return obj_DDLB; } void ULC_DDLB_ddlb ( DDLB *obj_DDLB) { // This is the implementation file where I would like to use the informations from // the DDLB_COLL1 array! } int main() { obj_DDLB = ULC_DDLB_config_ddlb ( DDLB_COLL1, 10, 5); ULC_DDLB_ddlb (obj_DDLB); return 0; } ==================================================== If this is too complicated I can simply find an easier more ineffecient way, but I really find this would be a good fit for my project since all I have to do, is set my drop down list box once with the ULC_DDLB_config_ddlb() function and then just fetch the ULC_DDLB_ddlb(obj_DDLB) function and access all the info's via the obj_DDLB pointer using the points to operator "->". I really would appreciate any help on how I can store the address of an array of structures in the respective places in the above example flagged by [***] ! Sincerely, thanking all in advance! PS. PLease note, I haven't shown the code for any testing of pointers returned by malloc or any free()'s in order to keep the code short and simple! -- Best regards Roberto Tag: broken samples....

    - Soliciting user input in an edit box Hello, I have an application in which a dialog contains an object that does some processing, during which it calls a callback function in the parent dialog. I would like to prompt the user to input something in an edit box in the dialog and suspend processing until the user input is complete (either the user hits <enter> or clicks a button, etc.). Then the callback function will return the user input. I could do this with a modal dialog that pops up. However, I don't want a separate dialog just for the input. Rather, I would like the edit box to behave like a modal component. Is there a way to suspend processing and wait on input in this way? Any help would be greatly appreciated.

    - Calling managed function from unmanaged code Hi to all! I am writing my first .NET app and I already have to subclass .NET window and work with unmanged code to get notification about any content being copied into clipboard. Here's a relevant part of my code: #pragma unamanged #include <windows.h> namespace UnManagedCode { void* lpFunc; // Pointer to managed function to be called void RegisterManagedNotificationFunc(void* lpFunc) { lpManagedFunc = lpFunc; } extern "C" long __cdecl UnManagedWinProc(HWND hWnd, unsigned int uMsg, unsigned int wParam, long lParam) { // Check to see if we have been notified of new data on the clipboard if(uMsg == WM_DRAWCLIPBOARD) { // Call a managed func __asm{call lpManagedFunc}; // Pass this message to another registered viewer window behind // TODO } // Pass control and data to default window procedure and return its return value to OS return CallWindowProc((WNDPROC)lngPrevWinProc, hWnd, uMsg, wParam, lParam); } } #pragma managed namespace ClipBoardApp { ................ private: System::Void SystemClipBoard_ContentsChanged() { // Called by unmanaged part as a notification event for managed part // TODO } } Now how will the unmanaged part of the code be able to detemine the pointer to managed function 'Void SystemClipBoard_ContentsChanged'?

    - VC++ 2005/2008 failed to open a file whose filename encoded in MBCS? Hi All, I've run across a problem of failing to open a file whose filename is encoded in traditional Chinese (BIG5). The example program is shown below. I've conducted a test using VC++ 2008 express, VC++ 2005 and VC++ 6.0, all on Windows XP-sp2 and found the programs compiled by VC++ 2008 and 2005 failed to open the file and hence to access the content. However, the program compiled vc++ 6.0 succeeded to do it. Almost the program settings are using the default ones except the following three items: 1) debug mode; 2) using MBCS; 3) no pre-compiled header. The file, =AD=BA=AD=B6.txt, is composed of a string of "=AD=BA=AD=B6.txt" a= nd the file, a.txt, is also composed of a string of "This is a string".

    - WAB (Windows Address Book) I'm trying to enumerate the WAB, which has names and email addresses. There seem to be two ways to do this, the old APIs load and call wab32.dll's WABOpen function and new (Vista-only) APIs that use the IContactManager COM interface. I have some code working for both of these ways, but in both cases it only sees the address book entries from Outlook Express/Windows Mail. It does not get any address book entries from Outlook. I'm wondering if I'm missing something in these APIs, or if Outlook does not make its (local contacts) list available via the APIs? -- Scott McPhillips [VC++ MVP] Tag: broken samples.... Tag: 295296

    - Can LoadIcon be used to load the icon of another process Hello LoadIcon take HInstance as one of its parameters. We usually use LoadIcon to load the icon of the current process instance: LoadIcon(hInstance, MAKEINTRESOURCE(...)) Can it be used to load the icon resource of another process?

    - Forward declaration of managed class: howto? Hi, I'm using VC++ 2008 Express. I have this managed class: ref class C1 { private: UINT i; public: C1() { //code }; void MyMethod() { //code }; } How am I to forward declare this class and it's public members? What do I have to put in the header file? I'd like to include the header file in another class, create an instance of C1 and access it's public members. However, if I only write ref class C1; it complains when trying to create an instance (using gcnew keyword) because it doesn't find the appropriate constructor. Now, if I do add it in the forward declaration this way ref class C1 { C1(); }; then it works but it complains at the definition of the class: error C2011...class redefinition. But the first should only be the declaration, not the definition. So, how to declare only but not define in the header file? I've searched for "forward declaration" a lot but didn't find anything satisfying. All I found was forward declaring the class but without mentioning it's members. Armin Tag: broken samples....

    - RichTextBox problem I am writing a debug logger (in C++/CLI VS2005, .NET 2.0, though problem is general and probably applies to Win32). As messages arrive they are added to the end of RichTextBox. By default the RTB always scrolls to the end to show the most recent message. I would like to allow the user to stop automatic scrolling, by clicking in the RTB, so they can examine messages which interest them. However when more messages are being added to the end of the RTB it is difficult to stop the text moving and still allow the user to scroll the section of the text they are interested in. I found a way to do it using EM_GETSCROLLPOS to get the position before the new messages are added and EM_SETSCROLLPOS to restore it afterwards. However as the number of lines increases the value I set with EM_SETSCROLLPOS starts to get rounded down until I end up right at the beginning of the text. Does anyone know why this happens or how to stop it? Is there a better way to achieve what I want to than EM_GETSCROLLPOS, EM_SETSCROLLPOS? TIA, KK Tag: broken samples.... Tag: 295217

    - C++ program paste paragraph of text Hello, I'm writing a C++ program that scans emails for words on our school "banned word list". I have got to the point where we can paste text from an email into command line which gets saved in a .txt file called 'emailscan' - this is then read by ifstream and scanned for the chosen word which if found is returned with its location The problem is that we cannot paste more than a single paragraph of text. For example if we copy an entire email, which more often than not contains several carriage returns, only the first block of text before the first carriage return is fed into the emailscan.txt file and subsequently only this part of the email is scanned. Is there a way of ignoring/discarding carriage returns or converting text after the cin >> operator in order to merge all the text into one 'paragraph'? Tag: broken samples.... Tag: 295195

The process is not started from my VC project, but already run as a Windows service for a while and I want to attach to it to see some of its variables' status or something. I have the related source codes, symbol files (PDB) and the binary file (running binary, including an exe and several dlls) of the same version. I opened the project in VC and using Debug --> Attach to attach the process, it is successful -- but the running binary exe and related dynamically loaded DLLs are not run from the VC project (I mean from Debug/Release directory of the VC project).

    - Bug with UNICODE and std::vector? Hello all, Im not sure, but I get some pretty strange results here. When I run this program debug compiled but NOT in debug mode, or release compiled I get an exception, sometimes immediately, sometimes after some time. If I run in debug mode, everything runs fine. I THINK it has something to do with reallocating of the vector if its capacity is too small. If I replace all UNICODE stuff with "normal" characters, I don't have any problem. anyone the same experience? Or am I doing something wrong?

    - Problem with placement operator delete [] I was trying to implement placement new and delete in my applicaiton as follows, class A{ int i; public: void * operator new[] (size_t size, Allocator alloc) { return alloc.Alloc(size); } void operator delete[] (void *ptr, Allocator alloc) { alloc.Free(ptr); } }; class B { Allocator &alloc; A *ap; public: B(Allocator a) : alloc(a) { ap = new(alloc) A[50]; .... } ~B() { // Since there is no way to call placement delete explicitly I have to do this A::operator delete[] (ap, alloc); } } Now the problem is, the placement new[] gets "size" as (sizeof(A) *50 + 4) the extra 4 bytes are added by the compiler for keeping track of the array dimension (i.e 50). Which means alloc.Alloc() actually allocates 204 bytes. Suppose the pointer which Alloc returned is 0x000100, Now compiler automatically adjusts it to 0x000104 to offset those extra 4 bytes and "ap" gets a value 0x000104. Now when I call placement delete[] directly then I pass 0x000104 to Free, but actually I should pass 0x000100. But for this I will have to subtract those 4 bytes from "ap". But I think that a very bad solution, Is there any better way to call placement delete[] so that we don't have to take care of the above mentioned 4 byte adjustment. Regards Tag: broken samples....

Anyhow, I have entered the following: ============================================= #include <stdio.h> #include <conio.h> #include <stdlib.h> #include "Main.h" //ACM152 HEADER FILE struct list { int value; struct list *next; }; int main(void) { struct list n1, n2; n1.next = &n2; return 0; //Breakpoint here! } ============================================== My question is, in debug mode, when my program stops at the breakpoint and I put my cursor over the "n1.next" I read this: n1.next = 0x0012fec0 {value=0xcccccccc next=0xcccccccc {value=??? next=???}} I guess that the 0x0012fec0 is the address of the n2 strucure which is stored into n1.next. But I don't understand what the rest means! I never assigned a value to "value" and yet why does it show that value is equal to 0xcccccccc ? And what does the "next=0xcccccccc" mean? And the doozee! what does the {value=??? next=???} mean? Any feedback appreciated. -- Best regards Robert Tag: broken samples.... Tag: 295090

    - SetLayeredWindowAttributes()?

    - Strange struct definition Hello everyone, This is what I found when reading atl/com internal implementation code (e.g. ATLCOM.h), for example in the definition of VARIANT. I show similar code segment below. I think the purpose of such struct definition is, defining struct and a variable of the type (in this sample type tFoo) altogether, any other benefits of using such type of definition? (I have such question is because I always use typdef to define a struct type, and then using a separate statement to define a vraible of the type, not merge type definition and variable definition together.)

Most C++ samples (OLE DB Providers & Tools) would not even compile with 2005
and 2008, mostly for embarrasing (defaulting to int) reasons like:

1. untyped const
2. even undeclared variables (also assumed to be int) like for(i = 0; blah,
blah blah)

Now that your compiler got better (and all these "wonders" are gone) it
would be nice to ask different teams to make sure that their samples still
compile... Practical example, in the Platform SDK, samples, dataaccess,
oledb, rowsetviewer... This application is also (binary) delivered as a
tool... So, this is like telling customers: we didn't even bother to rebuild
our tools... :-)

Daniel
