Okay. Thanks.
I re-read Jeffrey Ritchter's section on file-mapping. I believe using a file-mapping virtual memory is an effective, if not, the best way to share data across processes.

Hold an appropriate CFont object somewhere (for instance, as a member variable of the parent dialog) and set it as the one used for your static with CWnd::SetFont. As you only need to "boldize" the current font and leave all other aspects unchanged, you can construct it from what your static already has (see CFont::CreateFontIndirect, CWnd::GetFont and CFont::GetLogFont), changing only LOGFONT::lfWeight.

That is a *great* title. 'Bold, the text of static box'. It's almost poetic.

You could use the Crystal Report API engine, however it's just about reached the end of it's lifetime and I can tell you with a great degree of experience with all things Crystal and C++ that you really, really, really *do* want to use the ActiveX RDC (Report Design Component)
The crystal reports developers help file CrystalDevHelp.chm that is installed with Crystal Reports contains the full reference for using the API in the section titled "The Crystal Report Engine Class Library Reference".
We've used the API for many years but we're switching all our development to the ActiveX for many reasons: It's the only method they fully support, it's the only method they want people to use because their dropping the API by the looks of it quite soon, the ActiveX RDC has increasingly (after each release) more functionality than any other method.
Whenever they add a new function they only seem to be adding it to the ActiveX from now on.
But most importantly, it's far, far easier to use the ActiveX and there is no more overhead than any other method.

Hello Mr. Cardinal,
Thanks for reply !
But i have to use CR API engine ...
Because my BOSS told me that i don't register any ActiveX in the user computers
So, i have to use API engine ... right ?
If i use CR API engine then i don't need to register any ActiveX or DLL ??

even if you use the API, you still have to deploy a whole lot of DLLs into the user's "Program Files\Shared Files\..." directory and "%windir%\system32" directory...

Hello Hadi, even if you use the api you *still* need to install many .dll files as well as register some of them on the end users computer. There is no avoiding that. The API method just allows you to easily call functions in Crystal Report's .dll files, it doesn't wrap that functionality inside your program so that you don't need to include anything else. There is no way to do that.
Either way you have to register *something* on the end user's computer and both the API method and the RDC (activex) method are royalty free so you're in the same situation whichever way you go except for the very important facts that the ActiveX has more functionality, is easier to use for the programmer and will continue to be supported in future by Crystal Decisions.
I'm my own boss so I do what's best always! <grin>
However,it sounds like your going to have to explain the situation to your boss.
Specifically the information you should look at before you speak with the boss is look at the Crystal Reports developer's help file that I mentioned previously under the sections regarding deployment which will list for you each file that you have to include with your application for both the API method and the ActiveX method.
Good luck

You can turn off border and set "Static edge" extended style to achieve a semiflat look, or you need to use owner draw control.

Does Visual C++ support the statvfs object? If not, is there an object that is used to retrieve information about a partition (total size, size used, ect)?

Hi! I am develop a little application for a pocket pc with embedded Visual C++ 3.0... I tried to use the vector class of the stl, but I found out that there is no stl for embedded Visual C++, so I looked for a MFC class... but there are so many classes (CArray, CTypedPtrArray,...)...
Can anyone tell me what kind of mfc class I could use instead of the stl vector class?!?!? I need an array who stores pointer to a class (like "class CMeasureItem*")...
-- Sorry for my bad english!!!
Nice greets, Daniel.

Hi,
I have a MFC dialog app. Now, when I open an other dialog from the main one :
CSomeDialog dlg;
dlg.DoModal();
i want to access to some public member variable (for example CString m_Name) of the main dlg FROM the second dialog.. how to do this ?
Thanks for helping a beginner !
|
|

|

give the second dialog a pointer or reference to the first dialog.
void C1stDlg::OnY()
{
C2ndDlg d;
d.m_pFirstDialog = this;
d.DoModal();
}
void C2ndDlg::OnX()
{
m_pFirstDialog->m_Name = "Abe Lincoln";
}

When i press a button in my program, i get this message:
Unhandled exception at 0x00ef86a6 in MP3.exe: 0xC0000005: Access violation reading location 0x00000110.
And the strange part is that I get this message even before it has executed any of the procedures for the event of that button. It hasn't even come to the case line
case IDC_CONVERT:
When it pops up with the message.
This only happens if I, before I press the button, press another button which prompts the user to choose an ACM compressor driver. Here are the code for the button that i press before i press the second button which generates the message:
i = SendMessage(ghFormatHandle, LB_GETCURSEL, 0, 0);
j = SendMessage(ghTagHandle, LB_GETCURSEL, 0, 0);
hCurrentDriver = (HACMDRIVERID)SendMessage(ghFormatHandle, LB_GETITEMDATA, i, 0);
id = (HACMDRIVERID)SendMessage(ghTagHandle, LB_GETITEMDATA, j, 0);
SendMessage(ghFormatHandle, LB_GETTEXT, i, (LPARAM)szFormatName);
details.cbStruct = sizeof(details);
acmDriverDetails(id, &details, 0);
strcpy(szDriverName, details.szLongName);
SetDlgItemText(ghMainWnd, IDC_DRIVERNAME, szDriverName);
SetDlgItemText(ghMainWnd, IDC_FORMAT, szFormatName);
EndDialog(ghChooseWnd, 0);
I have found out that if i remove the hCurrentDriver = (HACMDRIVERID)SendMessage(ghFormatHandle, LB_GETITEMDATA, i, 0); line, no error happens! what could be wrong? Here's the call stack when the error happens:
LameACM.acm!00ef86a6() <--
winmm.dll!76b431ad()
msacm32.dll!77be4b5d()
MP3.exe!0040118e()
e877e88c()
(it's at the arrow when the error happens)
And here's the assembly code I get redirected to:
00EF86A0 push esi
00EF86A1 mov esi,dword ptr [esp+8]
00EF86A5 push edi
00EF86A6 mov edi,dword ptr [esi+110h] <---- THIS LINE
00EF86AC cmp dword ptr [edi],0FFF88E3Bh
00EF86B2 je 00EF86BC
00EF86B4 pop edi
00EF86B5 mov eax,0FFFFFFFDh
It jumps to the line marked with "THIS LINE".
The value of edi is 24653 and the value of esi and eax is 0.
Please help, I have no idea what could be wrong.
You're very welcome to email me to help me solve this error, thanks a ton!

Have you checked the return value assigned to i?
|
|
|
|

you must use a NULL pointer

Hi,
I recently installed the latest Platform SDK on Windows 2000 and now my Oct 2001 version of MSDN won't open. Has anyone had this problem before? When I try to launch the MSDN I get the following error:
Cannot open the file: c:\Program Files\Microsoft Visual Studio\MSDN\2001OCT\1033\MSDN130.COL.
I verified that the file is there, so I'm kind of confused about what is going on. I also tried uninstalling it and I get the same error.
Any help would be greatly appreciated.
Thanks,
Craig
