Hi,
I'm writing a utility application which needs to send and receive messages to/from a plugin I've written for another application, but I'm not sure where to start looking...
The plugin is developed using an architecture derived from COM (apparently) and I've got this up and running and talking to its host app just fine. My own utility application is also up and running and working fine. Now I need to send messages back and forth between the two.
I don't think I can use custom Window messages as the plugin doesn't have a window it just runs inside the host app. I'm investigating network related stuff but I'm guessing this is overcomplicating things.
Any advice would be greatly appreciated.
Cheers,
Simon

If they are on the same machine, look up WM_COPYDATA in MSDN.

You can also post messages to a thread[^].
But if you're using COM, shouldn't you be using events?

You need to implement the connnection point in your com.

screw COM, it's for VB programmers 
There are multiple options you have. You could try the following...
- Use sockets. CSocket kicks butt for simple communication and free of charge you also them communcating on different machines.
- Create a dummy window and try using a registered windows message (RegisterWindowMessage in MSDN).
- Use pipes. Never done this myself but its another form of process communcation.
- If you really want to pass a lot of data and want it to be very speedy but at the same time a bit of a management nightmare try creating some shared memory between the applications.

Guys,
Thanks to all of you for going to the trouble of answering my plea. CodeProject rules!
I plan to start investigating CSocket first as the next stage of development is a multi-machine version of the app anyway - GeMe you just saved me from another embarrassing post!
Thanks for all your great feedback though.

Does anyone know how to make a cube with a circular hole (Cylinder) across it?
Thanks
|
|
|
|

You can build "faces" with holes by using tesellators...
The code looks something like this:
GLUtesselator* pTess1 = gluNewTess();
glNewList(m_nIdDisplayList, GL_COMPILE);
gluTessCallback(pTess1, GLU_TESS_BEGIN, (void (CALLBACK *)()) glBegin);
gluTessCallback(pTess1, GLU_TESS_END, (void (CALLBACK *)()) glEnd);
gluTessCallback(pTess1, GLU_TESS_VERTEX, (void (CALLBACK *)()) glu_vertex);
gluTessCallback(pTess1, GLU_TESS_ERROR, (void (CALLBACK *)())tess_error_callback );
glNormal3f(0.f, 0.f, -1.f);
gluTessBeginPolygon(pTess1, NULL);
// Outer loop
gluTessBeginContour(pTess1);
gluTessVertex(pTess1,...);
gluTessEndContour(pTess1);
// Inner loops
gluTessBeginContour(pTess1);
gluTessVertex(pTess1, ...);
gluTessEndContour(pTess1);
...
gluTessEndPolygon(pTess1);

Thank you, but it doesn't work to me. 
If you could put the hole code you will made me a grat favour. Thanks

Yep.

I found some errors in Win95, in conjunction with MFC. One of them is that SetBkMode is not working properly.
1. How can I determine thename of component responsible for the function?
2. Can I transfer (and distribute) the working component from Win98 or XP to Win95?

Are you talking about SetBkMode() itself, or the wrapper around it, CDC::SetBkMode()? What is it that is not working? Perhaps a code snippet would better illustrate the problem.

What do you mean by "working component?"

Hi,
1. I found the error. I am working with the CDC wrapper. Under certain circumstances the BkMode was not set. Even though it worked well in Win98 and XP, despite that the default BkMode is per definition OPAQUE.
The reason not to set the BkMode was, that BkColor will not be set either. Painting occurs in the OnCtlColor function, and in the mentioned case it returns a bit map brush to paint the background. I thought BkMode does not apply here - and XP and Win98 think the same way. However XP does not take an offence when using SetBkMode in this situation, so now it's working in all three systems 
2. "Working component": I'm using CRichEditCtrl. It's functionality has been gradually increased since Win95. I took the corresponding components, for example riched20.dll from XP or from Win98SE and installed them in Win98 1sted and Win95; they work fine.
I was thinking of a way like this.
Do you know of a cross-reference between functions and components (DLLs)?
In Win95 the GetWindowPlacement function always returns a negative value in rect.right (rect.buttom is ok). In my system it is always (correct value - 5428), but I'm not sure if it is an universal number like the gravitational constant. I would like to try to replace the respective component of Windows.
Thanks anyway

Hi
I have a directory where i want to get a directory listing of all files.
How can i achieve this by using MFC classes?

I've found something that is quite unusual happening to my VC source files. Occasionally, when I compile, I get errors due to one character having been changed in one of my source files, or the src or include files in my Visual Studio directories. Usually the character is simply changed from lower to upper case, it seems at random.
For instance, today I had this change in my xlocale file, which prevented me compiling:
***** goodXLOCALE
static const mask * __cdecl classic_table() _THROW0()
***** badXLOCALE
static coNst mask * __cdecl classic_table() _THROW0()
*****Has anyone else ever seen this? Does anyone have any clue as to what it might be?
I look forward to hearing suggestions!

I have never seen it but it almost sounds like a virus or something similar if it is randomly changing data on the hard drive.

Hi
How i can to create my ones callback function????
Thank.

Are you wanting to know how to create a callback funtion? If so, it depends on the context. Generally, however, you'll want to use the CALLBACK data type.

Another solution is __stdcall.
unsigned int __stdcall Function(datatype param);

(sorry for the repost but this is really bugging me still):
The first time i call EncryptString (below) I pass "asdf" it encrypts to to be a length of 25 and encrypts it right. But when i try to encrypt a 2539 length string it returns a string of a length of 225 and only partically encrypted. Why is this happening and how do I fix it?
CString CEncyptionClass::EncryptString(CString m_strUnencryptedString)
{
//variables
//Date:11 22 03
CString m_strResultingText;
HCRYPTPROV hProv = NULL;
HCRYPTKEY hKey = NULL;
HCRYPTHASH hHash = NULL;
DWORD dwLength;
BYTE * pbBuffer;
LPTSTR m_tContents=ConvertCStringToChar(m_strUnencryptedString);
TCHAR szLocalPassword[] = _T("alongrandompassword");
//
// Get handle to user default provider.
if (CryptAcquireContext(&hProv, NULL, NULL, PROV_RSA_FULL, 0))
{
// Create hash object.
if (CryptCreateHash(hProv, CALG_MD5, 0, 0, &hHash))
{
// Hash password string.
dwLength = _tcslen(szLocalPassword);
if (CryptHashData(hHash, (BYTE *)szLocalPassword, dwLength, 0))
{
// Create block cipher session key based on hash of the password.
if (CryptDeriveKey(hProv, CALG_RC4, hHash, CRYPT_EXPORTABLE, &hKey))
{
dwLength= _tcslen(m_tContents);
pbBuffer=(BYTE*)malloc(dwLength);
if (pbBuffer != NULL)
{
memcpy(pbBuffer, m_tContents, dwLength);
if (CryptEncrypt(hKey, 0, true, 0, pbBuffer, &dwLength, dwLength))
{
m_strResultingText.Format("%s",pbBuffer);
CString strShow;
strShow.Format("After: %s \r\n(%s)\r\n %d %d", m_strResultingText,m_tContents,strlen((const char*) pbBuffer) ,dwLength);
MessageBox(strShow);
}
free(pbBuffer);
}
CryptDestroyKey(hKey); // Release provider handle.
}
}
CryptDestroyHash(hHash); // Destroy session key.
}
CryptReleaseContext(hProv, 0);
}
return m_strResultingText;
}

You sure it's not MessageBox not showing full string?... I assume you may get not printable characters after encoding.

The length of pbBuffer and m_strResultText is 225 .. the plain text string is 2539

That means according to your code:
LPTSTR m_tContents=ConvertCStringToChar(m_strUnencryptedString);
returns 225 length string...
Check ConvertCStringToChar function.
