    - Adjusting printing settings in MFC Greetings! I have an application where a vector font is printed. There are a few parameters (line width and colour, # of rows and columns) that can be adjusted for printing. What I wonder is how I would best integrate it into the printing framework of an MFC SDI application. In particular, I wonder about the following things: - There is a print setup dialog, but that seems to only be a printer setup dialog - is there a way I can add controls to influence the generated layout? - Also, using the print preview, is there a way to either start the print setup dialog or a custom setup dialog so that you can quicker see the effects of your changes? - Lastly, though not that important, why are there only three zoom levels in the preview? I observe that anything between one and ten pixels shows up the same in the preview, but different on the printer - I guess one could see the differences when zooming in closer ... is there a way to? cheers Uli Tag: Do specified libraries always get linked?

    - Icon in a child window! Hello everyone, This question requires you to know "Checker3" program from Petzold's book. All help is appreciated! I started chapter 9 (Child Window controls) of Petzold's book and as I started reading this chapter, it started to reference stuff we did in chapter 7, more particularly the "Checker3" program. So I immediately, stopped what I was reading and went back to review "Checker3" so I would be up to speed with the particularities of this sample program. All is OKAY... But you know silly me ! I always have to dig further than I have to. For the ones that are familliar with this example!!!! I am curious to know, what if we wanted to have a title bar and an icon in every one of the 25 child windows of the checker board. So first of all I tried to add the following line just before we would register the second wndClass window: wndclass.style = CS_HREDRAW |CS_VREDRAW; But then I thought to myself, this doesn't make sence, since this only allows re-drawing when vertical or horizontal resizes are done. So I commented out that line. Then I changed the following line just before we would register the second wndClass window from : wndclass.hIcon = NULL; to wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION); But that didn't help either. It clearly states on P.301 of Charles Petzold's book where he talks about the 4 fields that are required in the wndClass structure for registering the Checker3_Child class. The field in question is the hIcon field and he says: "The hIcon field is set to NULL because child windows such as the ones in Checker3 do not required Icons" However, what if we would want them to require Icons, is there something to set in CreateWindow or in wndClass or is it just impossible to have Icons or title bars in child windows ? I have read up on the CreateWindow function which for the 3rd parameter (dwStyle)states: "[in] Specifies the style of the window being created. This parameter can be a combination of window styles, plus the control styles indicated in the Remarks section." I looked at the available control styles... I found they don't really apply to what I am trying to do! However I did not try to experiment with them. If you need to see the whole program, just let me know and I will post it. -- Best regards Robert Tag: Do specified libraries always get linked? Tag: 259175

What is the relation between processId (which we come to know from the task manager) and hInstance (which is one of the parameter passed in the winmain function) of a program? Or there isn't any relation at all? if yes..why? as both give us the unique number related to a running program.. Thanks and Regards, Yogesh Joshi Tag: Do specified libraries always get linked?

    - Final and Cieled and nothing in C++ Has the fact that both Java and C# are garbage collected, and C++ in not, anything to do with the fact that there is no language item to prevent a class from being inherired from? I once read that Java and C# implement this feature for preformance, but the C++ creators said it was not worse the effort. So because Java and C# are garbage collected, in their case is it worse the effort? What is the connection? Tag: Do specified libraries always get linked? Tag: 259153

    - Prog. doesn't do waht its supposed to. Hi, I hate when I understand a piece of code and I know what its supposed to do, but then when I run it, there is a mysterious flaw, where to look now??????? Anyways this is the problem: I am finishing up chapter 8 of Petzold's book (Timers) and I seem to be stuck at the last program sample called "WhatClr" on page 352. I have looked it over for typo's but don't see anything wrong. I undertsand the logic but the program doesn't do what it claims. Its simply supposed to display the color of the current pixel underneath my pointer or as he says it "the pixel currently underneath the hot point of the mouse cursor." I don't know what he means by "Hot point" I guess he means the tip of my pointer? Anyhow if anyone is familliar with this code fragment, I would appreciate you taking a quick look at it.

    - Why should I code in header file [Visual studio C++ 2005]? Hi, In VC++.Net 2005 visual studio, if I create a new winform drag and drop a button, then double click it to write click event code, then it auto generates the template code for the event in Form1.h file rather than Form1.cpp file. This behaviour is against standard C++ coding standards, where my header file is supposed to just have declarations. I read in other topics that this is due to C# association of single file concept with the winform. Can someone (from MS or MS experts) explain why is this done? and how can I avoid it to generate template code in header file and write my code in .cpp file?

    - parameter passing between VC and VB Google is not my friend tonight. Or I am just being too impatient. Anyway can someone point me to relevant MSDN articles (or other up-to-date technical info) regarding parameter passing between C DLLs and VB programs. I haven't done that since the 16-bits days (VC1.5 & VB3). I hope to be able to use my old, trusty VC6, and the client would be VB.net. Not VB6, does that make a difference? I suppose I am really asking if VB.net is allowed to call unmanaged code. I seem to recall some special header was needed in order to be able to access (and return) VB strings from C. Has accessing non-Unicode C-style (zero-terminated) strings gotten any easier from the VB side, these last 10 years or so :-) Thanks in advance for pointers and hints, Bernard.

    - VS2005 is blocking when compiling two projects simultaneously VS2005 has the possibility to start several project builds in parallel. I found it nice, because I have a dual core. But I found, that there might be problems with this feature: The two build processes might block, if they work on the same file. (or perhaps on files in the same directory) The build process can be stopped without problems but the build can't be restarted corrrectly. Temporarily I switched back to compile only one project at a time, but I would prefer this feature to work correctly. Is it already a known bug, is there a Service Pack with fix? P.S. I think the developers of VS2005 will not get any reports through WinQual/OCA because the stopping of the build process breaks the deadlock. Tag: Do specified libraries always get linked? Tag: 259067

    - Sector reading and writing Hi All, I have problem in reading and writing to the sector beyond 6GB of data. The direct function Calls are used to deal with sector reading and writing. // First a handle is created using the following code. CreateFile(_devicename, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); // Then it is made to point to sector using the following. SetFilePointerEx (hDevice, L,&L1, FILE_BEGIN) //Reading of the sector is done using the following ReadFile (hDevice, buffer, 512*numberofsectors, &bytesread, NULL); //Writing to the sector is done as follows. WriteFile (hDevice, buffer, 512*numberofsectors,&byteswrite, NULL); I got the program in MSDN to know the hard disk details, so sure with size of sector. Reading and writing is done on block of the sectors, i.e, 100 * 1024. I am creating a image file of the read sector, and using this image file I am restoring back the contents of the disk or drive. There is no problem in reading and writing of data till 6GB it is working fine with no loss of data. Beyong 6Gb, I am able to create the image, but after writing the data i am unable see the contents. No files can be seen, but the size is reflected. But after that whats actually happening, not able to track it. Program is written in VC++.Net on Windows XP. Is there any limit or restriction of the harddisk or OS(whatever dont know exactly) after certain amount of data. Kindly suggest if any idea regarding this. Regards, sumana.

I did a search for semaphore c++ and came across this page: http://windowssdk.msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref22/html/T_System_Threading_Semaphore.asp I look under the sample for C++ and in part it has things like (I snipped a lot of code): #using <System.dll> public ref class Example { private: static Semaphore^ _pool; public: static void Main() { _pool = gcnew Semaphore( 0,3 ); for ( int i = 1; i <= 5; i++ ) { Thread^ t = gcnew Thread( gcnew ParameterizedThreadStart( Worker ) ); } } private: static void Worker( Object^ num ) { ... } }; AFAIK #using <System.dll> is not C++. static Semaphore^ _pool; is not C++. Thread^ t = gcnew Thread(... is not C++. Why does MSDN say this is C++ when it is obvoiusly something else? Tag: Do specified libraries always get linked? Tag: 259055

    - Moving and copying files I'm working on a utility program to move files from one directory to another at a controlled rate and under controlled circumstances. My logic is such that if MoveFile returns an error (from/to different media) it defers to CopyFile with deletion of the original file. The problem is I can't test the logic because I can't get MoveFile to fail. Even if I'm trying to move a file from my hard drive to the network it won't fail. In general that's good but I can't guarantee what it will behave that way in all circumstances. First, could someone explain to me what it won't fail? Does MoveFile have a built in CopyFile? Second, is there a way to force it to fail so I can track the logic to make sure that I'm putting out a viable program? TIA, Lilith Tag: Do specified libraries always get linked? Tag: 259045

    - thread-safeness and static CStrings I have some statically defined strings, as in: static CString strThisIsStatic = "Hello"; I have a thread that references my static CStrings with statements like: CString m_LocalString; m_LocalString = strThisIsStatic; if (m_LocalString.CompareNoCase(strThisIsStatic)) ... I am never modifying the strings ocntained within those staticall-defined CStrings. Is it thread-safe to do the above kind of referencing to statically defined CStrings? In general, is it thread-safe to reference statically-defined objects, as along as I never do anything to modify the statically-defined objects from with the thread? - Roger Garrett Tag: Do specified libraries always get linked?

    - windows.h winsock.h and winsock2.h problem Hi, When compiling some program which included a header file from a library I created I got a lot of errors saying that struct etc in winsock2.h where already defined in winsock.h. Looking through the windows.h winsock2.h and winsock.h I noticed that apparently winsock2.h should always be included before winsock.h. Doing that seemed to have solved the problem. However since windows.h is normally the first file included in stdafx.h I have to remember with every project to include winsock2.h manually before it. Am I doing something wrong and or is there a better way to do this? I'd rather not have to remember this kind of stuff but just be able to include a header file when I need it. -- Regards, Ron AF Greve http://moonlit.xs4all.nl Tag: Do specified libraries always get linked?

    - ConvertStringToBSTR Linker error Hi there, I'm having linker problems with the ConvertStringToBSTR function. I have included comsupp.lib as this thread suggests... http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=145979&SiteID=1 But it is still not working. If I run a search for comsupp.lib on my PC I come across it in the following paths, C:\Program Files\Microsoft Platform SDK\Lib\AMD64 C:\Program Files\Microsoft Platform SDK\Lib\IA64 C:\Program Files\Microsoft Visual Studio 8\VC\lib C:\Program Files\Microsoft Visual Studio 8\VC\lib\amd64 I am not including any of the AMD ones either in VC's global directories or the projects specific directories, but the following is... C:\Program Files\Microsoft Platform SDK\Lib\ Does it automatically recurse the directories? The only one out of those directories that is included is the "C:\Program Files\Microsoft Visual Studio 8\VC\lib" one. Any suggestions on this would be really helpful.. as mentioned above, I have actually included comsupp.lib in the linker inputs for the project. Thanks loads in advance Nick.

    - SetParent() from WS_POPUP I am creating a ListView through CreateWindowEx(). It works fine when I create it as a child window as so: hControl = CreateWindowEx(WS_EX_CLIENTEDGE, WC_LISTVIEW, NULL, WS_VISIBLE | WS_CHILD | LVS_REPORT, 300, 100, 100, 100, hWnd, NULL, NULL, NULL); However, I want to create the control with no parent, then add it to the parent form later. Something like this... hControl = CreateWindowEx(WS_EX_CLIENTEDGE, WC_LISTVIEW, NULL, LVS_REPORT, 300, 100, 100, 100, NULL, NULL, NULL, NULL); SetParent(hControl, hWnd); The drawing of the ListView in that code goofs up the window drawing. I played arround a bit and came up with this: hControl = CreateWindowEx(WS_EX_CLIENTEDGE, WC_LISTVIEW, NULL, WS_POPUP, 100, 100, 100, 100, NULL, NULL, NULL, NULL); SetParent(hControl, hWnd); dwStyle = GetWindowLong(hControl, GWL_STYLE); dwStyle &= ~(WS_CLIPSIBLINGS | WS_POPUP); dwStyle |= WS_CHILD | WS_VISIBLE | LVS_REPORT; SetWindowLong(hControl, GWL_STYLE, dwStyle); ShowWindow(hControl, SW_SHOW); This works for the drawing, but if you right click in the header area, you will get a stack error.

    - stl map/set and multithreading Hi All, I've got a question regarding using STL map and set class in a multithreaded situation. I'm developing a database program. The program fetches and parses millions of records from the database and build a map/set to allow faster access to records by certain rules. The type of map/set is: map<long, set<long> > m_map; It maps "category id" to a set of "record ids". So that I can easily get a set of record IDs by accessing m_map[CATEGORY_ID] later on. The fetch-and-parsing process is very long, and it takes more than 3 minutes in usual cases. So you know, during this period, I wanted to give the user some feedback on the UI, hopefully to show some already parsed records to users. So I put the parsing process in a background thread, it's doing all the fetching job and stuff such as m_map[CATEGORY_ID].insert(RECORD_ID);. And the UI access the map every few seconds, to fetch out record IDs. Of course, first, it used map<long, set<long> >::const_iterator to remember "CATEGORY_ID", and set<long>::const_iterator to remember the current position of RECORD_ID in the set, do a little iteration, and fetch all the relevant record IDs out. (well, during this process, the background thread is still running) I noticed that if I let the background thread finish before attempting to refresh the UI, it works flawlessly. But if I do what's planned above, refresh UI every few seconds, some how lots of records were slipped out. The debug message shows 100 m_map[CATEGORY_ID].insert(RECORD_ID) insertions (of course RECORD_IDs are all different), but the size of the set is only like 40 items or 30 items, it's random. I further checked the debug message and found that the thread is running fine with no errors or exceptions, all records are parsed the way they supposed to be. Now, why is the number of set entries less than the number of insertions (again, keys are all different)? My guess would be some kind of protection, when another thread is accessing the set, all insertions are dismissed. Is that true? How do I avoid this? I even tried pausing the thread while the UI refresh process and got no luck. I don't think it's a problem with compile settings, relevant options are all checked. Any help will be much appreciated. Thanks in advance, -- He Shiming Tag: Do specified libraries always get linked? Tag: 259001

    - stdext::checked_array_iterator problem In Visual Studio 2005 (beta 2, we hope our company will roll out the final version soon), std::copy gives a compiler warning if you try to copy to an unchecked buffer. It wants you to use stdext::checked_array_iterator instead of a simple pointer to the buffer, so I changed: char* mBuffer; to stdext::checked_array_iterator<char*> mBuffer; and std::copy now works fine. Unfortunately, now the simple and valid line mBuffer[0] = 0; triggers a debug assert. Inspecting <iterator>, it appears that the debug check that is done in operator[] does not accept an offset of zero! The question is: Is this a bug or a feature? If it is a bug, does anybody know whether it is fixed in the final version of 2005? And is there a work-around, other than writing our own checked_array_iterator? We may do that eventually anyway, so we can use the same code on WinCE as well, which does not have the stdext::checked_array_iterator at all, but it would be a lot easier if we could use the standard stdext::checked_array_iterator on WinXP at least.

VC++ 7.1

In a project's property pages, do all libs specified in Linker/Input
actually get linked into the app in all cases, or do only those that are
actually used get linked?

Thanks,

Normally the linker only links these symbols which are referenced. All
other will be thrown away...

But you can enable, that unreferenced data should be kept:
/OPT:NOREF
=> "Project|Settings|Linker|Optimization|References"
