Please see screen shot with command window:
www.bipom.com/support/cc51shot.png
As you see i started new command line in Windows Vista and run cc51.com.
It runs and return usage info.
Any other messages/warnings.
So it works.
This is compiler for C programs. I also can compile files under Vista with it.
So it works well.
Please note, I have Vista 32bit, not 64bit.

Since I don't have a copy of cc51.com, I couldn't do any more tests to find out your problem  Sorry.
But from the sample screen and your original post, I have a question,
Are you missing something ?
The usage of CC51.com shows that you have to give the <name> right ? And the options too...
is it like C:\Temp>CC51.com some_file.c -q > res.txt

I simple use cc51 without parameters to show that it works.
Thank you for help.

Hello friend,
I have created DLL for the device using serial comport.
After sending the command, I am receiving ANSI characters raw data from device as below:
e.g 1>
0x00 0x08 0x1b 0x1a 0x10 0x00 0x02 0x00 0x00 .......
e.g. 2>
0x10 0x3c 0x0F 0x00 0x08 .......
I want to store this data in MS ACCESS (.mdb) file.
Problem :
1> Whenever trying to store the data, it stores into the database data
up to NUL(0x00) character.
2> Not able to store NUL(0x00) and data content after NUL character in database.
Please give me any suggestions for storing the data in database.
Thank you

Have you tried using an "OLE Object" field rather than a "Text" field?

Thanks for the reply.
But OLE object will just embed or link any file .doc or .jpg with the excel.
I want to store special charcters in the database.
Is there any way other than it.

About special character conversion,
Try encoding the characters, you may get some idea from here[^] and here[^]

To store binary data as such in MS ACCESS, use BLOB data type. See this [^]for details.

Hi,
The below code works fine in VC6.
double i =-3.3;
double j =2.4;
double result = pow(i,j);
if (result <1.0E-13)
{
printf("true");
}
else
{
printf("false");
}
In VC6, IF condition is true. Whereas in VC8, its failing.
Could any one explain the reason, why its failing in VC8.
Thanks,
Anandi

Have you looked at the actual value in both? In VS6, the value of result is -1.#IND000, indicating NaN for floating-point numbers.

Yes. In VC6, result value is -1.#IND000000000 whereas in VC8 -1.#IND000000000000

So rather than call pow() with invalid input, why not check the base value first, or call _isnan() on the result?

Because VC8 is compliant with IEEE754[^], whereas VC6 wasn't (did VC6 comply with any standards, I wonder, 'cause it didn't comply with the C++ standard either. Anyway.)

What is your definition of 'works fine'?

Hello,
I have a C++/MFC application, which can be extended by its users by means of a PlugIn interface. This interface uses simple dll mechanisms (no COM). Now I want to add a functionality to allow these PlugIns to be written in .NET languages. Therefore I created a wrapper PlugIn, which sits between the MFC application and the .NET user PlugIn. This works very well so far. However, I have one problem. Some PlugIns might require to extend the user interface of the MFC app by controls in order to apply specific settings. The method for this, which is to be implemented in the native dlls, has the following prototype:
HWND CreateSettingsWindow(HWND wndParent);
Where wndParent is the window handle of the parent window on which the control should be placed.
What I do in the wrapper is create a .NET form control from this handle and pass it to the wrapped .NET PlugIn like this.
HWND CreateSettingsWindow(HWND wndParent)
{
System::Windows::Forms::Control^ ctrl = System::Windows::Forms::Control::FromHandle((System::IntPtr)wndParent);
System::Windows::Forms::Control^ ctrlSettings = (*this->m_pWrappedPlugIn)->CreateSettingsWindow(ctrl);
if (ctrlSettings != nullptr)
{
return (HWND)ctrlSettings->Handle.ToPointer();
}
else
{
return NULL;
}
}
The wrapped .NET PlugIn now creates its control (derived from System.Windows.Forms.UserControl) and attaches it to the controls collection of the parent window:
public override System.Windows.Forms.Control CreateSettingsWindow(System.Windows.Forms.Control parent)
{
MySettingsControl ctrl = new MySettingsControl();
parent.Controls.Add(ctrl);
return ctrl;
}
The control is created correctly and as it seems I can even access it from the MFC application (at least I can read its size). But it will not show up on the parent window. Regardless what I do (visible property, show method, ...) it will not become visible.
Any idea what could be wrong with my approach or what might be missing would be very helpful.
Thank you very much

Did you make the HWND you originally created visible as well as the .NET part of the deal?

Yes, I did.
I found the problem. Obviously System::Windows::Forms::Control::FromHandle fails for window handles, which were created by Win32/MFC and not with .NET. Thinking about it, this makes sense.
Luckily I found a nice tutorial on the web, which pointed me into the right direction:
http://www.tech-archive.net/Archive/DotNet/microsoft.public.dotnet.languages.vc/2005-07/msg00752.html
So I moved the code, which attaches to control to the parent window, from the .NET to the native code section.
The .NET control creation changed simply to the following:
public override System.Windows.Forms.Control CreateSettingsWindow()
{
return new MySettingsControl();
}
And the attachment to the parent uses the good old Win32 function SetParent:
HWND CreateSettingsWindow(HWND wndParent)
{
System::Windows::Forms::Control^ ctrlSettings = (*this->m_pWrappedPlugIn)->CreateSettingsWindow();
if (ctrlSettings != nullptr)
{
::SetParent((HWND)ctrlSettings->Handle.ToPointer(), wndParent);
return (HWND)ctrlSettings->Handle.ToPointer();
}
else
{
return NULL;
}
}
Might it be worthwhile to publish an article about this here on codeproject?
Thanks

Definitely - it sounds like something that a) could trip up other people, and b) isn't documented as clearly as it could be.

Hi,
I am opening an application through another application using CreateProcess().
If the exe is running already I am sending a message through PostMessage otherwise I am opening run the exe and send message.
I found the running instance using FindWindow(). But some times FindWindow() is returning " NON-NULL" although app is not running.
I am confused with this behavior.
My Window Caption is "DDKK";
And My code to FindWindow() is:
HWND hWindow=NULL;
hWindow=::FindWindow(NULL,_T("DDKK"));
if(hWindow==NULL)
{
STARTUPINFO si = { sizeof(si) };
PROCESS_INFORMATION pi;
CreateProcess (CSanProApp::GetAppPath(0) + _T("abc.exe"),
_T(" und"),NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);
Sleep(4000);
}
::PostMessage(hWindow,Opendialog,0,0);
Please suggest me any solution, why the FindWindow() is returning NON-NULL value although window is not running.

Check out EnumProcesses to find if a process is running
You can also use OpenProcess, if it returns NULL process is not running etc etc.
You need to google first, if you have "It's urgent please" mentioned in your question.

FindowWindow() takes 2 parameter: classname, windowname....
Is there any method to register window with desired name.
My app using below code to register window
<br />
if( !CFrameWnd::PreCreateWindow(cs) )<br />
return FALSE;<br />
<br />
cs.dwExStyle &= ~WS_EX_CLIENTEDGE;<br />
cs.lpszClass = AfxRegisterWndClass(NULL,NULL,NULL,AfxGetApp()->LoadIcon(IDR_MAINFRAME));<br />
<br />
cs.style |= WS_CLIPCHILDREN|WS_CLIPSIBLINGS;<br />
return TRUE;<br />

Yes, but that does not answer my question. When FindWindow() returns a non-NULL window handle, how are you verifying that the application is not running?
