I am trying to write two classes that work togeather. One is a color storage class (CSoilColor) and a lookup table class (CColorChart). When I added a member variable to CSoilColor to hold a pointer to a CColorChart object, the compiler choked. Each header file has an include to each other so they should recognize each other, but from the error they apparently do not. Even though the comiler chokes, the development environment recognizes the CColorChart member variable because it allows me access to the CColorChart's members in the CSoilColor's cpp file.
Here are the class definitions:
#include "SoilColor.h"
class CColorChart
{
public:
bool IsValidColor(int nHue, int nValue, int nChroma);
bool GetHue(int nHueID, CString& sHueName);
bool GetRGBcolor(CSoilColor SC, COLORREF* RGBcolor);
void InitChart();
bool GetColorName(int nHue, int nValue, int Chroma, CString& sColorName);
CColorChart();
virtual ~CColorChart();
private:
CString Hue[nMAXHUES];
COLORCHART Chart[nMAXHUES][nMAXVALUES][nMAXCHROMAS];
};
=====================================================
#include "ColorChart.h"
class CSoilColor
{
public:
CSoilColor();
virtual ~CSoilColor();
int GetChroma();
int GetValue();
int GetHue();
COLORREF GetRGBcolor();
bool SetColor(int nHue, int nValue, int nChroma);
private:
CColorChart* m_pColorChart; //ERROR HERE
int m_nHue;
int m_nValue;
int m_nChroma;
};
I think it is probably a simple error, but I am going crazy  trying to find it! If anyone has Ideas, please let me know. Thank You.

Use forward declaration instead of #include:
class CColorChart;
class CSoilColor
{
...
CColorChar *m_pColorChart;
};

Now that you mention it I did know that at one point.
Thank you very much.

hi
if i work in VC for a while, i am unable to access the toolbar list that appears whenever you type something like CString p.
is it lack of memory? If i restart my PC it works again...

Simple answer:
VC is screwy, and has a habit of doing that just to annoy you 
usually it'll stop working if there is a syntax error somewhere in your code.
Visual Assist (http://www.wholetomato.com/[^]) is a handy Visual Studio addin that fixes lots of these problems

The phrase "Help me! I'm turning into a grapefruit!" was something utterly non-sensical that I picked up the top of my head to go as the text to a scrolly screensaver on my University Linux account. It drew lots of amusement from people who saw it, so it ended up as my email sig as well (and eventually when I came to create a decent website for myself, I thought up the name "grapefruitopia" as it rolls off the tongue nicely, is pretty bizarre, but easy to remember.)

When Intellisense stops working, it's usually due to a syntax error earlier in the function. However, I have seen it just stop showing the popup list (the VC status bar indicates that Intellisense is otherwise operating fine), and in that case just close & restart VC.

I need to develop an application that performs a query on
a database and stores the query output in an Excel document.
How can I develop the Excel document management (file creation
and data storage) ?
Thanks a lot

You need to use Ole Automation....

Use DAO, ODBC (.csv, .xls)
Or export to the Excel xml file format (you'll get the reference with this key search on MSDN : "Microsoft Office Drawing File Format". Using xml allows you to create charts or pivot tables as well.
And if you need the .xls format itself, yes the simplest way to do it is through Automation, at least if you are running Windows.
Final point, you may buy a finished product (softartisan).
Or crack the binary file format.
And I swallow a small raisin.

Hi,
how can i catch Scroll Mouse events (like OnVScroll) in my ListControl ?
Marco
|
|
|
|
|
derive your own class from CListCtrl (if you're using MFC) and add a message handler for WM_VSCROLL.
in plain win32 you will need to replace the default listctrl window proc with your own and handle WM_VSCROLL manually.
|
|
|
|
|
Thanxs,
can u give me the some more implementation hints, because i don't know such
message related thinks ?

What means "SVR4 system"?
Hi, everyone!
The following statements are taken from a C/C++
project.
--------
/* some SVR4 systems omit an underscore */

What means "SVR4" system? I use Google to search
but failed to connect. Anyone knows?

System V Relase 4.0 -- a UNIX version released in 1989 that later became what is now called Solaris (the OS of Sun Microsystems).
Joaquín M López Muñoz

PS: What I've said is not entirely true: Solaris is not the only descendant of SVR4. Novel also grew it to Novell Unixware, and apparently SCO Unix also has its roots in this OS.

Thanks, Joaquín pal!
Your reply helps a lot. Reading source codes that
can run on a lot of systems needs a lot knowlegde, I
think.

Does anyone else have the problem that every now and again VC6 loses one of your classes.
I just deleted a function and the class has disapeared from the Workspace. Its still included as part of the project and compiles fine?!?!
This has happened before and by removng and adding the files again it came back up but this isn't happening now!!!

This happens every now and then.
Normaly, I close the Workspace, exit the VC++-IDE and delete the *.ncd, *.opt and *.position files that sit in the same directory like my *.dsw.
After a restart of the IDE all is fine again.
