Hey all.
I noticed the VS_VERSION_INFO resource that is inside my program that I am building.
I am building code that displays the current version in various places. I would like to be able to pull the values from this VS_VERSION_INFO resource, instead of having to declare a version-info variable in my class -- which just makes more places for me to update it.
I checked MSDN about this and all that I can come up with is GetFileVersionInfo() method. I do not want to have to use a method if I don't have to that acutally looks at its own .EXE to determine the current version.
I am wondering if there is another method or some other way to grab those values from the resource at compile time?
Thanks!

Hi,
Search google for a class 'CModuleVersion' which can be used as
TCHAR szPath[MAX_PATH];
GetModuleFileName(NULL,szPath,MAX_PATH);
CModuleVersion ver;
if(ver.GetFileVersionInfo( szPath , TRUE)){
CString s;
s.Format(IDS_STRING61504,HIWORD(ver.dwFileVersionMS), LOWORD(ver.dwFileVersionMS), HIWORD(ver.dwFileVersionLS));
SetDlgItemText(IDC_VERSION , s );//UnicodeConversion
}

Does anyone know off hand why I cannot add an additional
control to my control heavy dialog using the Dialog editor in VC++?
If I remove an existing control, I can then
add. I'm hitting a limit somewhere perhaps?
(Its a busy dialog... )
Thanks for your help.

It took a while but here you go!
0x00050000 - 0x0005FFFF
from the MSDN article "TN028: Context-Sensitive Help Support".
That,s 65,535 possible IDs.
You should not be hitting a limit. Unless you are running out of memory or the resource editor has an unrealistic limit. I have placed large numbers of controls on dialog boxes before without any problems.
As an experiment, may be you could try creating and placing controls on a dialog programaticaly and see when it fails.
Good luck!

As harsh as the statement might sound, I would have to agree.
It really sounds like the time for a UI redesign.

Get a life. There are words for geeks like you, but I will spare
this fine forum. You have no idea what the requirements/design problems are. Nor do you know whether or not I'm the designer!
So you are completely out of line to suggest that I lack design skills.
The fact is, the software does need UI rework, but I've seen many a fine
application with more than 256 controls on a single dialog.

VC++ (v6, anyway) only allows 256 (I think...) controls to be placed using the dialog editor. The rest you'll have to manually put in the .rc file and not use the dialog editor, or create them dynamically.

Thank you Ryan and John for some useful
input!
It does indeed seem to be the case that the VC++ allows one to only add
256 controls via the dialog editor.
A shame. Somewhat of an arbitrary limit, no?
Of course, I can simply add them by hand as Ryan suggests.
And speaking of design weaknesses... wouldn't surprise me if Christian
was the geek who decided a byte was enough to store the control count in
the VC++ Dialog Editor and that there is no need to inform the user when
the limit is reached !
Excellent help from the forum, despite the flames... Thanks again.

I have a class structure forming a linked list where there is another class (declared as private within the main class) such as
class Link
{
private:
class LinkElement {
friend class Link...
...
Is it possible to access the PRIVATE members of the LinkElement class from a function that is not part of either of the two classes? I am trying to go through the linked list in a thread and trying to set various pointers to both the class Link and LinkElement but can't get access to that member. Is this possible or am I wasting my time?
|
|
|
|
|
#define private public
Or cast (LinkElement *)(classpointer + whatoffestis)
Or make the accessing class a friend or make som
accessor functions.

Thanks for the speedy reply, but I'm a bit confused with your answer. Here is what compiles and what doesn't for me
cLink::cLinkElement *pPointer; (compiles with the class warning that it's not initialized to anything)
now doing this: pPointer->pNextLink = NULL; (it shows up fine on class view btw but I get this compilation error: error C2248: 'pNextLink' : cannot access private member declared in class 'cLink::cLinkElement'
Is there anyway to get around this by not making the privates publics?

You do get what private means, right? It's an implementation detail that you shouldn't rely on, because somebody is guaranteed to change it the moment you start monkeying about with it.
Ignore the suggestion of #define private public (although made in jest), because that's the sort of thing that shots you in the foot later on.
You can fudge a solution by declaring an identical class/struct (with the same compiler packing options, etc!), but without the use of private. If you're lucky, the compiler will generate matching object layouts, and you can reinterpret_cast a pointer from one type to the other, and then access the private members through that.
Use of this technique is extremely brittle, and if I was your boss or peer, I'd be distinctly unimpressed with you, and make you junk that code.
Generally speaking, what you're trying to do indicates you don't understand the problem correctly, you don't understand the language properly, or you have a crap design that needs rethinking.
And if this is homework, then go back to the textbooks

You are right on the issue that I have crap design, but this is no means homework. I have been programming c++ for about 2 years, completely self taught, and learning by my mistakes as I go along, since I have no one to teach me and I am not doing this for a living.
I have found a workaround to this by not declaring that member private anymore.
My understanding of private is that it's a member of a class that can be accessed only by the functions of that class and/or the class object, correct?
Also, although your criticism is appreciated, and I know I am a really bad coder (should have seen me 2 years ago!!!!) a little help would be appreciated to go along with the criticism.

Point taken
What exactly are you trying to achieve? I might be able to provide more constructive guidance with a brief outline of the task you're trying to solve.

I have read some of the replies and the best way to learn is by doing.
If you wish to access a private memvebers of a class from a function that is not part of the class, you need to do one of three things: Provide member functions in your class to access the private member variables (preferded method), declare your function(s) as a friend of the class (this says the function knows what it is doing), or make the member data public (this is normaly a bad idea).
I recommend the books by Bruce Eckel for learning more about the C++ language itself, although they concern the langauge and not any specific OS.
Good luck, and have fun!
P.S. I love programming!

Thanks to everyone for their replies. Although I don't think that books can help me out any more because I am stubborn and never learn until I make the mistake. John's comment about creating another member function to get the details from the private members sounds the best way (don't know why I didn't think of it myself...been at it for 10 hours today, probably that's why!)
Thanks, again.

I would like to know if it is possible to have BOTH VC++ 7.1 and VC++ 6 installed on the same computer without anything going haywire?

|

Dunno why no-one has responded - am I the only one who does this ? I've run both for months with no hassles.

Same here. Works perfectly!
As a matter of fact, I literally have VC 6, and VS .NET 2002 and just recently installed VS .NET 2003 as well and I've had no problems.

Yes, all three versions 6, 7, and 7.1 work just fine. We have a few systems at work running all three versions.

I'm trying to make an application that uses a speech recognizer engine but it should write from a .cpp file in the dialogbox defined in other .cpp file and I don't know how could I do.
Here is some of my code so you can understand me better:
In my main code1.cpp I have defined a edit box with a member variable. In my code it appears on this way:
<br />
CIVOCOMDlg::CIVOCOMDlg(CWnd* pParent )<br />
: CDialog(CIVOCOMDlg::IDD, pParent)<br />
{<br />
m_strHeard = _T("");<br />
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);<br />
}<br />
<br />
void CIVOCOMDlg::DoDataExchange(CDataExchange* pDX)<br />
{<br />
CDialog::DoDataExchange(pDX);<br />
DDX_Text(pDX, IDC_GOT, m_strHeard);<br />
}<br />
Then in this code1.cpp I create a Grammar object:
<br />
BOOL loadGrammar( TCHAR *pszFile, BOOL bDictGram,<br />
ISRGramCommon **ppISRGramCommon )<br />
{<br />
...<br />
IUnknown * pIUnkGram;<br />
CGramDictSink *pGramDictSink = new CGramDictSink(NULL);<br />
pGramDictSink->AddRef();<br />
<br />
hRes = g_pISRCentral->GrammarLoad( SRGRMFMT_DICTATION, sData,<br />
pGramDictSink, IID_ISRGramNotifySink,<br />
&pIUnkGram );<br />
<br />
pGramDictSink->Release();<br />
...<br />
hRes = pIUnkGram->QueryInterface( IID_ISRGramCommon,(void **)ppISRGramCommon );<br />
pIUnkGram->Release();<br />
<br />
hRes = (*ppISRGramCommon)->Activate( NULL, FALSE, NULL );<br />
<br />
return SUCCEEDED( hRes );<br />
}<br />
In the code2.cpp file I have:
<br />
STDMETHODIMP CGramCFGSink::PhraseFinish( DWORD dwFlags,<br />
QWORD ,<br />
QWORD ,<br />
PSRPHRASE pSRPhrase,<br />
LPUNKNOWN )<br />
{<br />
if( !( dwFlags & ISRNOTEFIN_RECOGNIZED ) ||<br />
!( dwFlags & ISRNOTEFIN_THISGRAMMAR ) )<br />
{<br />
return S_OK;<br />
}<br />
<br />
PSRWORD pSRMax = (PSRWORD)( (BYTE*)pSRPhrase + pSRPhrase->dwSize );<br />
PSRWORD pSRWord = (PSRWORD)( pSRPhrase->abWords );<br />
TCHAR szText[256] = { _T('\0') };<br />
int nWords = 0;<br />
while( pSRWord < pSRMax )<br />
{<br />
if( nWords++ != 0 )<br />
_tcscat( szText, _T(" ") );<br />
<br />
_tcscat( szText, pSRWord->szWord );<br />
pSRWord = (PSRWORD)( (BYTE *)pSRWord + pSRWord->dwSize );<br />
}<br />
<br />
SetDlgItemText(m_hDlg, IDC_GOT, "Unrecognized\0");<br />
return S_OK;<br />
}<br />
This SetDlgItemText(m_hDlg, IDC_GOT, "Unrecognized\0"); doesn't work... It should write in the edit box the text "Unrecognized" whichever I say. I don't know what could I do so it works. Please, help me!
Thank you!
I have no idea

I'd like to make and edit control that only allows numeric entry with nothing else. Is the best way to do this through subclassing or simply deriving my control from CEdit. Also, what are the advantages or each? I'm new to this whole subclassing thing so I'm not really sure what it's best used for. Thanks in advance.

If the edit control is on a dialog box, select the styles property tab in the resource editor and check number. This only applies to integer values though and not floating point or doubles values.
If you need to validate that the contents will only be values of the form "00.00", then you will need to derive you own class from the edit control and override entry validation. In this case I sugest a search of codeproject and its' afiliates to find articles on overriding the edit control, who knows may be someone has already solved the problem for you.
