Not 100% sure as it's 2 years since I wrote GDI wrappers but I think SetDCBrushColor is that wierd API that is documented everywhere but doesn't exist/work anywhere, at least pre-Vista. I'm sure Google will confirm or deny this pretty quickly, it's worth a check. If memory serves there is an alternative possibly Ex variant which works at least in XP.

DC_BRUSH is defined in WinGDI.h iff _WIN32_WINNT >= 0x0500 so you need to be building for Windows 2000 or later to use it and linking to gdi32.lib of course.

Nothing is exactly what it seems but everything with seems can be unpicked.

what have you tried so far, and where are you stuck with the code ?

this looks like a homework, and if you don't try by yourself, how will you learn things ?

The big deal, my dear, is to fit all the above calculations in few classes...

1 meter = 39,370079 inch = 3,28084 foot

1 inch = 0,083333 foot = 0,0254 meter

1 foot = 0,3048 meter = 12 inches

Re: how to delete specific elements in a char pointer

10-Oct-07 22:58

Here is the declaration statement.

unsigned char *String;

Now i have made String point to "{abcdef}".

Here i need to delete the paranthesis, i.e, i need to delete the first and last character in 'String'.

How to make it point to a val of just "abcdef" without the first and last character??

Kindly help!

are you using MFC?
i.e. CString

Suggestion to the members:
prefix your main thread subject with [SOLVED] if it is solved.

Re: how to delete specific elements in a char pointer

10-Oct-07 23:45

Thanks for your concern.

Yes i use MFC.

By your question, I got an idea to convert it into a CString and apply delete and then save it back - something like this;

<br />
    unsigned char *String;<br />
	<br />
    CString cString,result;<br />
    cString="{abcdef}";<br />
    int n=cString.GetLength();<br />
    result=cString.Mid(1,n-2);<br />
<br />
    String = (BSTR)rest; <br />

However, here i am not able to store it back to 'String'. i am getting various compiler errors like

" error C2440: 'type cast' : cannot convert from 'class CString' to 'unsigned short *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called "

Need help in typecasting in the last line.

What is rest, and why are you trying to cast it into a BSTR, when what you wand is a unsigned char*?
And why unsigned char? Thats uncommon.
