have a look at the book The C++ Language from Bjarne stroustrup. Inside, he gives an example of "mathematic calculator" (about p.120).

No code actualy understands a mathematical expression! What I think you are looking for is a "Recursive Descent Parser"; the best example I ever found was in "Advanced C Programming" (may be out of print), it is much easier to understand than the one in "Bjarne stroustrup" book.

I want to hide my menu bar but I've read in msdn that a menu bar is always visible, but I think I've seen an application (running fullscreen, probably with WS_POPUP) has the ability to hide/unhide its menu bar.
Can we really do this using MFC ??

Hi,
What is the best way of using MFC's List to store data of this type?
typedef struct DATAGRAM
{
UINT packetID;
ip_header* ipHeader;
pcap_pkthdr* wpHeader;
const UCHAR* pkt_data;
} DATAGRAM;
ipHeader* etc are pointers to further structs. I tried plain CList DATAGRAM, DATAGRAM& and are having problems with code like:
packetCapture.AddTail(filledStruct);
The addtail is in a fairly fast loop and added data is going in fine and coming out of the list corrupted (due to something going out of scope before the operation is completed perhaps?)
I am probably doing something extremely retarded, any ideas?
|
|
|
|
|
Did you mean to do this instead?
packetCapture.AddTail (&filledStruct);
Also remember that filledStruct must be in scope for its address to be valid when you access the list after populating it. You might want to consider new()ing instances of DATAGRAM and adding those instances to the list. They will be around as long as your application runs since they're created on the heap. Be sure to free up this memory before your app exits.

Hi all,
I would be pleased if any one have an algorithm for building a software program to make a Gantt Chart i need to know the steps thanx all .

I'm writting my own Gantt control right now as i wasn't able to find anything suitable out on the web.
When i searched for existing Gantt related work the best (only) thing i found was :
http://ganttproject.sourceforge.net[^]
although this is all in Java it might provide a starting point.
I have tended to use MS Project as a guide to what kind of data needs to be stored and how to present the data in an interface. If you are going to have access to MS Project you may want to look at the database schema information provided with MSP. It can usually be found in the install directory e.g. C:\Program Files\Microsoft Office\Office\1033 and will be named OLE_DB.HTM, or PROJDB.HTM, or something similar depending on the version of MSP you have installed.

hi,
I am trying to understand the Plot Grafhical Library (great library that plots grafhs that i downloaded from the PGL homepage and not the one you can download on the code project site) by programming a small example. but after i run the appliaction i find myself facing the next message : "Unhandled exception in try2.exe (MFCO42D.DLL): 0x0000005: Access Violation"
this violation occures while the program tries to call for a constructor of one of the PGL classes (CPGLRegion), and the debugger brings me to GetThreaterMode() function (from viewhtml.cpp).
if someone knows what is the problem, please help.

Hello all,
please, does anybody know how to setup the RichTextControl (2.0) that it will appear only as the text on dialog box and not as edit field (e.g. that cursor changes and user can select it)?
I tried to set it as read only, but it doesn't help.
Thank to you all!

Strange. This should work.
VERIFY (myRichEditCtrl.SetReadOnly (TRUE));
ASSERT (myRichEditCtrl.GetStyle() & ES_READONLY);

Hi dear,
yes, sure setting it to read only works,
but then when you will move over control the cursor changes and and you can also select the text.
So it doesn't look like normal text.

Hi Katerina, what you are doing is right according to me. But, there is one more thing that you need to add. Override the PreTranslateMessage and enter the code given below:
BOOL CMyDialog::PreTranslateMessage(MSG *pMsg)
{
if (pMsg->message == WM_MOUSEMOVE && pMsg->wParam == MK_LBUTTON)
return (TRUE);
return (CMyDialog::PreTranslateMessage(pMsg));
}
Don't remove the read-only setting.
Hope this proves useful.

Hello,
I am experiencing a very strange "phenomenon":
When I compile a Visual C++ program in VS 2002
(no GUI, just console output) into
an exe on XP Home it runs smoothly. However,
when I give this to someone with an XP Pro
machine, it does not run but stops with an
exception error message box.
We have tested this on 3 different XPPro boxes now
and everywhere the same result.
When I compile the program with the same VS 2002
installed on a XPPro machine into an exe,
it runs BOTH on XPPro and XPHome.
I am really puzzled and have no clue why this happens.
Seems that in terms of OS at compilation time the exe's
are downward compatible but not upward.
Could anybody please help me and tell me what is going on?
Thank you so much in advance,
Tony

A lot depends on what the exception error is. Is this an MFC app or a pure Win32 app. Do you use the CommonControls dlls.

Thank you very much for your quick answer. I am not quite sure how
someone can tell if it is an MFC app or pure Win32 app? I assume
you see it if it contains MFC*.dll?
I used depends 2.1 to see which DLL's my App uses. I have attached below a list of all used DLLs. Note that Column1 and Column2 contain
the same list of dll's, I have just sorted Column2 by name to facilitate analysis.
Thank you so much for any help on this.
If I cannot find an answer on why this happens, do you think it is safe to say:
"Compiled exes will
always work on XP Home when compiled on XP Pro but not necessarily the
other way around."
If I knew this was true, I could always only compile the progs on XP Pro and be on the safe side.
Thanks again,
Tony

Absolutely not. It doesn't matter what OS you compile on. I could run VC 5 on Win 95, build a GUI app, and it would run on XP or 2K3 or whatever.
It would help if you posted the error message.

Mike,
thank you very much. I get an error message box that says:
"The application failed to initialize
properly (0xc0000135). Click on OK to terminate the application."
Do you have any idea what could cause this?
Thanks,

Hi,
Ithink it's problem about some Upgrades!!
Try this,
Upgrade WinXP (That your prog. didn't work on) with FrameWork1.1 avalable in microsoft site and run your prog again
I think it works good.
Please tell me if this solve your problem.
Yours Mamad,
|
|
|
|
|
Dear Mamad,
thanks so much for your answer.
I will try it out but doubt that it works.
Why? Because I think that Framework 1.1 you are talking
about is the .NET Framework. But I have coded in
pure VC++, not VC++.NET.
So I cannot really see how the framework would influence
my native code (no IL).
I will try it anyway.
Thanks again,
Tony
