If I setup a static variable like this:
[CODE]
// .h file
class DisplayLine
{
static SolidBrush s_solidBrush;
...
};
[/CODE]
and initialize it like this:
[CODE]
// .cpp file
SolidBrush DisplayLine::s_solidBrush(Color(255, 0, 255, 0));
[/CODE]
and then in the draw() routine do this:
[CODE]
void DisplayLine::Draw(Graphics *pGraphics)
{
// Draw the text
pGraphics->DrawString(buf, -1, &font_big, lineRect, &sFormat, &s_solidBrush);
}
[/CODE]
that the text will not draw due to the brush. Weird.
What am I doing wrong? Why is the brush not getting initialized?
I even tried adding this:
s_solidBrush.SetColor(Color(255, 0, 255, 0));
but that didn't help.

How do you know this??

Because if I creat a brush in the draw() method it works fine.
This works:
void DisplayLine::Draw(Graphics *pGraphics)
{
Font font_big(L"FIXEDSYS", 18, FontStyleBold, UnitPixel);
Font font_small(L"FIXEDSYS", 12, FontStyleBold, UnitPixel);
StringFormat sFormat = new StringFormat();
sFormat.SetAlignment(textAlign);
sFormat.SetLineAlignment(lineAlign);
SolidBrush a_solidBrush(Color(255, 0, 255, 0));
// Set text to display
wchar_t buf[20+1] = { 0 };
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, lineText.c_str(), (int)lineText.length(), buf, 20);
// Draw the text
pGraphics->DrawString(buf, -1, &font_big, lineRect, &sFormat, &a_solidBrush);
}
}
Even if I make the s_solidbrush public, it still does not work.

is this...
[CODE]
// .h file
class CduLine
{
static SolidBrush s_solidBrush;
...
};
actually this? (what is the CduLine class?)
[CODE]
// .h file
class DisplayLine
{
static SolidBrush s_solidBrush;
...
};
In CPP file, outside of any function...
SolidBrush DisplayLine::s_solidBrush(Color(255, 0, 255, 0));

Yes... My mistake... I was changing names to make things clear.
the definition is at the top of the file outside of any functions.
|
|

|

Geez at least SetColor should have worked 
Beats me but I'll keep looking at it...I would expect it to work!

by my understanding of what i've found in msdn the folowing code should redirect the output of "ping www.google.com" to a file...and well...it doesn't. Where did i go wrong?
STARTUPINFO StartupInfo;
PROCESS_INFORMATION ProcessInfo;
ULONG rc;
HANDLE hFakeStdOut = CreateFile(
"C:\\myfile.txt",
GENERIC_WRITE,
FILE_SHARE_WRITE,
NULL,
CREATE_ALWAYS,
FILE_ATTRIBUTE_NORMAL,
NULL
);
if(hFakeStdOut==INVALID_HANDLE_VALUE)
{
printf("CreateFile failed with %d\n",GetLastError());
return;
}
memset(&StartupInfo, 0, sizeof(StartupInfo));
StartupInfo.cb = sizeof(STARTUPINFO);
StartupInfo.dwFlags = STARTF_USESTDHANDLES;
StartupInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
StartupInfo.hStdOutput = hFakeStdOut;//GetStdHandle(STD_OUTPUT_HANDLE);
StartupInfo.hStdError = hFakeStdOut;//GetStdHandle(STD_ERROR_HANDLE);
char sCurDir[1023];
GetCurrentDirectory(1023,sCurDir);
if (!CreateProcess( NULL,
"ping www.google.com",
NULL,
NULL,
TRUE,
NULL,
NULL,
NULL,
&StartupInfo,
&ProcessInfo))
{
printf("Failed with %d\n",GetLastError());
}
WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
if(!GetExitCodeProcess(ProcessInfo.hProcess, &rc))
rc = 0;
CloseHandle(ProcessInfo.hThread);
CloseHandle(ProcessInfo.hProcess);
CloseHandle(hFakeStdOut);
I've been reading about this for about an hour now and i can't get it. Please help

I think that you should specify the full path to ping.exe (always a good habit, ask any *nix person, it prevents a command hijack), and put that path into the first parameter. Put the parameters to ping.exe (www.google.com) as the second parameter and see if that works.
I have had situations in the past where specifying everything as the command line fails, but breaking them up works. Dunno why, but try it.
Also, did you try using pipes as suggested in the MSDN article located at http://msdn.microsoft.com/library/en-us/dllproc/base/creating_a_child_process_with_redirected_input_and_output.asp[^]? Maybe it works with pipes but not with normal files? I would get the pipes version working first.
Peace!

Thanks but the full path is not the problem. Braking the args and actual module name did not work either.
This sucks  msdn says that a handle can be anything that supports Read() and Write() so a hadle to a file created by CreateFile shoul work. I realy don't get it

The handle needs to be inheritable:
try
SECURITY_ATTRIBUTES SecurityAttributes;
SecurityAttributes.nLength = sizeof(SECURITY_ATTRIBUTES);
SecurityAttributes.lpSecurityDescriptor = NULL;
SecurityAttributes.bInheritHandle = TRUE;
HANDLE hFakeStdOut = CreateFile(
"C:\\myfile.txt",
GENERIC_WRITE,
FILE_SHARE_WRITE,
&SecurityAttributes,
CREATE_ALWAYS,
FILE_ATTRIBUTE_NORMAL,
NULL
);

Thanks...but it still does not work

if u want to redirect the out put u can use any of the following ways...
SHELLEXECUTEINFO stInfo = {0};<br />
stInfo.fMask = SEE_MASK_NOCLOSEPROCESS;<br />
stInfo.cbSize = sizeof(SHELLEXECUTEINFO);<br />
stInfo.lpVerb = _T("open");<br />
stInfo.lpFile = _T("cmd");<br />
stInfo.lpParameters = _T("/c ping www.google.com > c:\\result.txt");<br />
stInfo.nShow = SW_SHOW;<br />
ShellExecuteEx( &stInfo );<br />
WaitForSingleObject(stInfo.hProcess, INFINITE);
or
STARTUPINFO StartupInfo;<br />
PROCESS_INFORMATION ProcessInfo;<br />
ULONG rc;<br />
memset(&StartupInfo, 0, sizeof(StartupInfo));<br />
StartupInfo.cb = sizeof(STARTUPINFO);<br />
if (!CreateProcess( _T("c:\\windows\\system32\\cmd.exe"),<br />
_T("/c ping www.google.com > c:\\result.txt"),<br />
NULL,<br />
NULL,<br />
TRUE,<br />
NULL, <br />
NULL, <br />
NULL,<br />
&StartupInfo,<br />
&ProcessInfo ))<br />
{<br />
printf("Failed with %d\n",GetLastError()); <br />
}<br />
WaitForSingleObject(ProcessInfo.hProcess, INFINITE);<br />
CloseHandle(ProcessInfo.hThread);<br />
CloseHandle(ProcessInfo.hProcess);

Exactly the way the tutorial describes it.
Keep at, hopefully it will begin to sink in. Also you might try this site[^]. But don't expect to actually "know" C++ in 21 days.

Hi,
Could you specify what exactly gives you headache, please?

O.K well since I seem to be in the right forums I'm gonna have alot of questions scince I've never really used C++ or any other scripting language before. I hope I'm not a bother. Anywho I was wondering how functions can be applied, like can they have random things in them or do they follow a specific set? Generally I'd like to know a tad more on functions.
I'm a true failure.

Can you explain what do you need?

First, C++ isn't a scripting language. Second, what books on C++ have you read?

How do i setup timers in a console application? Is it possible? does anyone know any tutorial on this matter?
Thanks

It is fairly simple. Take a look at the MSDN documentation for CreateTimerQueueTimer()

Thanks! Didn't know about this one

Second time this has happened eh? I say TimerQueueTimer and you say WaitableTimer. 6 to one tomatoes to another.

Either one would work ... I've just used WaitableTimers more than TimerQueues so I knew that one off-hand.
