    - Opening a new Form on top of the main form Basically I wanted to do the following: 1. Open a new form 2. Disable the main form while the new form is loaded. (prevent it from being accessed at all) 3. when the new form is closed, the main form will return to its original state. can anyone give me some pointers as to how to do that? this is what I have so far.... //upon clicking a button in the main form....

    - Any point in pre-creating a file for write performance? Hi! I'm creating a data accusition system which needs to dump data to disk, basically as fast as possible. I've used aligned buffers (VirtualAlloc) and overlapped unbuffered IO so far. The write speed is good, probably as good as it will get on my system (~35 MB/sec). I sort of expected to see a difference in speed when overwriting an already created file versus writing to a new file (in the favor of the already created file) because the old one would already be 'laid out' on disk. Is this the case? I dont see a difference, but I got a lot of space on my HD. Would it matter if the disk was almost full and badly fragmented? Thanks! Tag: My own icon for MessageBox ? Tag: 259309

    - Can pre-innitialized array be changed? Hi, I am reviewing some array stuff in 'C' and I would like to understand something. The code fragment below displays the words innitialized in the words array. =============================================== char words[][2][10] = { "We", "Are", "All", "Human" }; printf("All the words will be displayed. Press any number to continue! \n"); scanf("%d",&p); for(i = 0; i<2; i++) for(ii=0;ii<2;ii++) printf("Word > %s:\n",words[i][ii]); //words[1][1]="Nice"; printf("ENTER A NUMBER[#] TO EXIT: >> "); scanf("%d",&p); =============================================== Lets say that further down this program I would like to replace the last word "Human" to "Nice". Why wouldn't I be able to do it with the following line: words[1][1]="Nice"; Anyhow, if I try this, it gives the following error: c:\_DTS_PROGRAMMING\c\GREEN_OSBOURN_P177_PointersWithArrays\P177.cpp(108) : error C2440: '=' : cannot convert from 'const char [5]' to 'char [10]' The error seems to not be able to convert a 'const char' (Nice) to a char (as array defined). So is it that when we declare an array this way: char words[][2][10] = { "We", "Are", "All", "Human" }; then we cannot modify its contents anymore? Lets say we wnat to modify the contents, what do we do? I am reading a C book from Osborne and it shows many examples, but this scenario is not really shown, can someone help me resolve this issue... All much appreciated! -- Best regards Robert Tag: My own icon for MessageBox ? Tag: 259308

    - Can a class' static member func be a friend of that class? My class has a static creator function that will instantiate and initialize an object. The initialization requires access to private members.

    - Tracking down a access violation Hello, I'm getting an access violation when my program starts up. My program is linked to a few dll's of mine, and I think one of them is causing the access violation. Here's what Visual Studio says (7.1.3088): First-chance exception at 0x02b72e04 (GComm.dll) in runner.exe: 0xC0000005: Access violation reading location 0x00000000. The problem is that there is no source to display, only disassembly. I suspect there is a global object that accesses another global object not yet initialized. Can I somehow figure out what code is at location 0x02b72e04 in GComm.dll, or is there a better way? Since this happens before debugging even starts, it is difficult to find the problem.

    - OLE2A() problem Hi I'm using OLE2A(bstrVal) at many places in my COM. where bstrVal is usually the parameters passed to the COM method. What happens is that if somebody send bstrVal = NULL, than OLE2A() crashes. Is there any way I could REDEFINE the behaviour of the macro OLE2A so that it can take null argument too and return empty string instead of giving an exception. The macro is being used at lots of places and its really hard to replace it or add additional checks for null value. Please reply if there is any solution.

    - "Double dispatching" of operator-> Consider the following program: // P is designed to be some proxy for T template<class T> struct P { T* operator ->(); }; // PP<T> is designed to be some proxy for the proxy P<T> template<class T> struct PP { P<T> operator ->(); }; // Any old class class C { int f(); }; int main(int, char**) { PP<C> c; return c->f(); } This compiles successfully on MSVC6, MSVC8 (beta 2) and Comeau Online. How is C::f() found? (it is indeed being found, as can be confirmed by attempting to link it.) By what rule does "c->f()" get interpreted as "c.operator->().operator->().f()"? Usually one cannot do more than one "implicit conversion" in one go. Is there a special rule, or indeed a general rule that I am missing here? One can seemingly extend the example to further layers of indirection, e.g. template<class T> struct PPP { PP<T> operator ->(); }; template<class T> struct PPPP { PPP<T> operator ->(); }; then change PP<C> in main to be PPPP<C>.

    - message issue i'm trying to make the screen refresh continuously while still handling windows messages correctly. here's what i have: #define MYMSG 19000 PostMessage(hWnd, MYMSG, 0, 0); while (!bQuit) { if (PeekMessage (&msg, NULL, 0, 0, PM_REMOVE)) { TranslateMessage (&msg); DispatchMessage (&msg); } } ... case MYMSG: boardgraphics.drawboard(board); SwapBuffers (hDC); Sleep(10); PostMessage(hWnd, MYMSG, 0, 0); return 0; my understanding is that it should post MYMSG at the end of the queue, and that it will be read after any keyboard and mouse messages. however, the window doesn't seem to be handling keyboard and mouse messages. any ideas?

    - Help with strings in MS VC++ Express I need to know how to get from one comma delimited text string to many strings. from this: main_string = "onE,Two,Three , fouR,five, six " to these: string1 = "one" string2 = "two" string3 = "three" string4 = "four" string5 = "five" string6 = "six" the white space needs to be removed and the case needs to be all upper or lower. The result needs to be strings and not pointers or addresses in memory so I can test: string test = "three"; if (three == "three") some getlines will only have two strings some may have up to 10 Please help with examples, you input with exact syntax is greatly appreciated I have been struggling with not using pointers but every time I end up using them.

    - Emulating AtlWaitWithMessageLoop? Can it be done? I am not familiar enough with the queue servicing functions. They all seem to have little catch-22's that make me hesitant to fill in the empty "else" clause below. BOOL MyWaitWithMessageLoop(HANDLE hEvent) { MSG msg; DWORD dwWaitResult; while ( TRUE ) { dwWaitResult = MsgWaitForMultipleObjects(1, &hEvent, FALSE, INFINITE, QS_SENDMESSAGE | QS_POSTMESSAGE); if ( dwWaitResult == WAIT_OBJECT_0 ) return TRUE; else { /* empty the queue; check for WM_QUIT */ } } } For example, I am tempted to say while ( PeekMessage(&msg, hWndMe, 0, 0, TRUE) { if ( msg.message == WM_QUIT ) return FALSE; DispatchMessage(&msg); } but I read that PeekMessage() **automatically** dispatches 'sent' messages. I also read, of GetQueueStatus(), that "The presence of a QS_ flag in the return value does not guarantee that a subsequent call to the GetMessage or PeekMessage function will return a message" and that makes me hesitant to use GetQueueStatus(). How can I finish off this emulation of AtlWaitWithMessageLoop()? Thanks. Note that my window needn't worry about any input, timers, or anything that deals with it's being shown (it's never shown). -- - Vince Tag: My own icon for MessageBox ? Tag: 259247

    - 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: My own icon for MessageBox ?

    - 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: My own icon for MessageBox ? Tag: 259175

    - 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."

    - 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?

    - alt tab mystery i created a reversi game at http://www.coolgroups.com/reversigame2/ in C++. i noticed that, if i alt tab away from it in windows xp and alt tab back, the game screen is blank. however, if i do this on my win 2k system, the game screen shows up correctly. i'm using opengl and a separate thread for the graphics. any ideas why this might happen? btw, the game installs the source too. thanks.

    - linker error Hello, I've made a static lib using VSC++. I'm trying to call the library routine in another project that uses DDK compiler and I'm getting the following error advanced.obj : error LNK2019: unresolved external symbol "int __stdcall SaveXml(struct _XmlPortParams *)" (?SaveXml@@YGHPAU_XmlPortParams@@@Z) referenced in function "int __stdcall AdvancedDlgProc(struct HWND__ *,unsigned int,unsigned int,long)" (?AdvancedDlgProc@@YGHPAUHWND__@@IIJ@Z) objchk_w2K_x86\i386\Ctibhnp.dll : fatal error LNK1120: 1 unresolved externals I've even declared the function in librarry as __stdcall but that also does not solve the problem.

    - Help converting malloc to new Hi, I am new to c++ and I am converting a c program to c++. I changed malloc call to new and I am getting an exception violation. Here is the relevant piece of code. Compiler vc++ 7.0 (.Net 2003) SQLINTEGER nCols; SQLINTEGER cbColDataLength; PBYTE* pColumnData = NULL; === C style ==== pColumnData = (PBYTE*) malloc(nCols * sizeof(PBYTE)); pIndicators = malloc(nCols * sizeof(SQLINTEGER)); pColumnData[nCol] = (PBYTE) malloc(cbColDataLength) === C++ style ==== pColumnData = new PBYTE [nCols * sizeof(PBYTE)]; pIndicators = new SQLINTEGER [nCols * sizeof(SQLINTEGER)]; pColumnData[nCol] = *(new PBYTE [cbColDataLength]) I tried using my logical understanding of pointers but the compiler kept throwing me out. So looking at the compiler messsages I got it to compile by using the above syntax. Please help me in figuring out if this is correct. Thanks Prahalad Tag: My own icon for MessageBox ? Tag: 259090

    - 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. (yes, this is cross-posted to vc.lang and vb.winapi; apologies to whomever it irks ;-) Tag: My own icon for MessageBox ? Tag: 259079

    - __imp_ Linking question I've looked around and tried several suggestions on this topic, but to no avail. The program is C++ and getting LNK2019 error when trying to link in C functions from a DLL. I'm using eVc++4.0. The header file of the DLL looks like this. #define VEOCAMAPI_API __declspec(dllimport) extern "C"{ VEOCAMAPI_API HRESULT CamOpen(HANDLE* phCam); } I did a DUMPBIN /imports /symbols, and found this line: 0AD 00000000 UNDEF notype () External | __imp__CamOpen So the __imp__ is being added by the __declspec(dllimport) A DUMPBIN /exports /symbols on the library shows this line 5 4 00006D04 CamOpen So the linker says: error LNK2019: unresolved external symbol __imp__CamOpen referenced in function If I remove the VEOCAMAPI, The linker gives this error error LNK2019: unresolved external symbol _CamOpen referenced in function So how do I deal with the extra _ attached to the front of the function name?

    - 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: My own icon for MessageBox ? Tag: 259067

Hi Experts:

Under Windows XP, is there a way to force MessageBox() to display my own
little icon on its top-left corner (left end of the title bar)?

Thanks in Advance!

I suggest to post again in the UI group:

microsoft.public.win32.programmer.ui

On your way over take a look at MessageBoxIndirect() and MessageBoxEx()
which give you greater control than does MessageBox().
