Can you do it like this?
<br />
struct SStop<br />
{<br />
CString m_strCompany;<br />
CString m_strTown;<br />
CString m_strAddress;<br />
};<br />
<br />
class CTempRun<br />
{<br />
CString m_strDriver;<br />
CArray <SStop, SStop> m_astStop;<br />
};<br />

Hi,
This isn't a technical question so I'm not sure if it belongs here but I'm not sure where else I could ask, please let me know if I'm in the wrong place.
I want to publish a game that I coded in Visual C++ 6.0. Now what do I need to license in order to publish? Do I need to just have a legally purchased copy of Visual C++? Or do I actually have to have some sort of registered business with a business license?
Thanks!

No, if you own VC++, then you are fine.

now I am doing a job to capture the screen and the data format is .bmp,I want to compress it. not save it to bmp file and compress it but convert the data of bmp to data of jpg in memory,what should I do?
thanks a lot
|
|
|
|
|
In memory, it must be a bmp to be of any use to you. To save it to disk as a jpg, you need libjpg, or better yet, use GDI+.

could you tell me how to do it by GDI+
|

Read my articles on GDI+, I present a paint program I called 'doodle' ( so search Code Project for doodle ), which has all the code you need in it.

can you tell me how the Task Manager list processes in system. I have make lots of tests, and found it use neither toolhelp functions or EnumeProcess functions.
I want to drectly create a process that the Task Manager can not find with not using dll injection or remote thread.

I dont think it's possible to create such process.but you may create a process that can not be killed using task manager(windows service).

i would like to write a letter in the center of the screen and rotate it, but when i rotate my later - it moves from the centre, who knows how to make it ?
I tried this:
CString str = "W";
CFont Font;
Font.CreateFont(96,
0,
angle*10,
angle*10,
FW_NORMAL,
FALSE,
FALSE,
0,
ANSI_CHARSET,
OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,
ANTIALIASED_QUALITY,
DEFAULT_PITCH | FF_SWISS,
"Arial");
dc.SelectObject(&Font);
dc.Rectangle(0,0,100,100);
CSize size = dc.GetTextExtent(str);
int posx = 100-size.cx;
int posy = 100-size.cy;
dc.ExtTextOut(posx/2-sin(3.14*angle/180)*size.cx/2,posy/2+sin(3.14*angle/180)*size.cy/2,ETO_OPAQUE,NULL,str,NULL);
but it works properly only from 0 to 45...

The problem is that the letter is rotating around its bottom-left corner. Use SetTextAlign() to centre the text so it will rotate around the centre of the letter.

Is there a quick and easy way to get the username of the current Windows user?
|
|
|
|
|
Figured it out myself:
GetEnvironmentVariable("USERNAME", username, username_size)
|
|
|
|
|
GetUserName() is the preferred solution, because in some security settings, applications may be prevented from reading environment variables.

and here is second
[b]
GetUserName
The GetUserName function retrieves the user name of the current thread. This is the name of the user currently logged onto the system.
Windows 2000/XP: Use the GetUserNameEx function to retrieve the user name in a specified format. Additional information is provided by the IADsADSystemInfo interface.
BOOL GetUserName(
LPTSTR lpBuffer, // name buffer
LPDWORD nSize // size of name buffer
);
Parameters
lpBuffer
[out] Pointer to the buffer to receive the null-terminated string containing the user's logon name. If this buffer is not large enough to contain the entire user name, the function fails. A buffer size of (UNLEN + 1) characters will hold the maximum length user name including the terminating null character. UNLEN is defined in Lmcons.h.
nSize
[in/out] On input, specifies the maximum size, in TCHARs, of the buffer specified by the lpBuffer parameter. On output, receives the number of characters copied to the buffer, including the terminating null character.
If the buffer is too small, the function fails GetLastError returns ERROR_MORE_DATA. The nSize parameter receives the required buffer size.
