NM_CUSTOMDRAW

I try to handle "NM_CUSTOMDRAW" event for merging column. But it is not proper work to merge column.

From that I change the font color but not abstract the column.
Can any one help?
“How to merge column using Custom control event?”

For that should I implement CDRF_SKIPDEFAULT event for drawing sub item my self?

Then how to do self drawing control?

Off course i mean it. U must draw each column by your self when draw stage is CDDS_ITEMPREPAINT. And must return CDRF_SKIPDEFAULT.

I am not as familiar with mfc.

Can you help me about draw each column by programmer.

Or you can give me any related project in which CDRF_SKIPDEFAULT return value is handle.

my platform is xp sp2 and vs2005. I downloaded the lastest platform sdk from microsoft website. But there is no declaration of GetExtendedTcpTable in iphlpapi.h. Then i check the output section of iphlpapi.dll, and there is.
My purpose is to make the program in static link, so i neek the dll link implicitly. Is there only way i use this function by linking the dll explicitly?
Thans for everyone who give me help.

Macro Preprocessing

31-Jan-07 19:14

Hi,

I am parsing C files to identify variable usage using lex and yacc.
But I am facing problem regarding macros, since a macro definition may contain some variable name. Since its within body of macro, I am not able to track the variable usage.
So I wanted to know, is there any way we can get this macro preprocessing done so that we have our C file with all macros expanded?

Any thoughts or ideas on this...please let me know
Thanks in advance.

You can use the /P[^] option with Microsoft compilers.

CMap problem

~Worried!31-Jan-07 18:59

31-Jan-07 18:59

I am using a CMap

CMap<cstring,lpcstr,int,int> my_map;
my_map.SetAt("abc",1);
my_map.SetAt("xyz",22);
...

I need this map to be globaly accessible in my application, therefore I am initialising this in a common header file of my application.

But when i compile the coe I get following errors:

: error C2143: syntax error : missing ';' before '.'
: error C2501: 'my_map' : missing storage-class or type specifiers
: error C2371: 'my_map' : redefinition; different basic types
: see declaration of 'my_map'

Any pointers?

CMap is declared in afxtempl.h, you need to include that file.

In this case, use extern.
In common header,

extern CMap my_map;

And in one on cpp file define it.
i.e.

CMap my_map;

Even then the error does not go.

Actually there is no seperate .cpp file here. This header file contains all the constants etc required in my app. I just want to associate some key-value pairs so that they can be searched some time later in the applicataion.
