Hi all !
I have a SDI apllication in wich I start another apllication (from the document). I need to make some things when this application has closed so I start a new thread that waits for the termination of this application.
But how can I send a message to the main Thread ?? I read that we cannot pass MFC classes from a thread to another so I cannot pass a pointer to the main window.
Thanks

Although CWnd object are not thread safe, they are a wrapper for the windows HWND member, which is. Pass this through as a parameter to the tread and send the message to that.

Hum hum !
Yes that was so easy that I didn't think about that 
Thanks a lot for reply

Ok so That works but the problem is I have to pass also the handle to the process I have to wait for.
So I create a structure with the HWND (window) and the HANDLE (process) and I send this to the Thread. This structure is a local one so datas are no more valid after the functions is left.
What is the best solution ? Dynamically create the structure and delete it from within the thread ?? Or what?

You get better results by using "PostThreadMessage" and related macros. And never use CWnd* as as already mentioned.
Try this @ home. (B&B)

I still have to pass two parameters: the HANDLE of the process I have to wait for and the Id of the main Thread. So The problem remains the same...
Or is it a way to retrieve the ThreadId of the application main's Thread ?

Hi
I want to write information to the registry 'HKEY_LOCAL_MACHINE\Software'.
I don't think it is possible by using the MFC function (WriteProfileString).
How can i fix the problem without having to fear that it won't run perfectly on all windows systems?
What do you guys/girls recommend me?
Greetings
Jens

No its not possible using the standard MFC functions. We needed to do the same in our app. We took the existing code in the GEtProfileString() and the ancillary functions, pasted them verbatum and changed all the HKEY_CURRENT_USER references to HKEY_LOCAL_MACHINE. After adding a LM to the end of each function name it worked really well.
The only issue you may have is access rights. Depending on how the admin sets up registry access, your application could possible be blocked from writing to HLM.

Use CRegKey class to read and write to registry.

I've just read this article:
'http://www.endurasoft.com/techtalk/regdemo2.htm'
Does this API work on all Windows version correctly?

Those SDK Functions will surely work on all window platforms.

Well, i'll try the CRegKey class first out.
If that works good enough, i won't use the SDK functions.

Okey. CRegKey is easier than SDK methods. If any help, feel free to ask.

Jijo.

Yes. Totally right.
I just discovered that CRegKey is a wrapper around the SDK methods which allows easier usage / less coding work.
(We all love that .. don't we )
So using the SDK functions directly wouldn't be smart.
I already managed to deleted/create a new key at the 'HKEY_LOCAL_MACHINE' so that's cool.
But i miss 1 big feature (maybe you can still help me with this one).
Let's say i want to copy all contents (all keys and all values of it subkeys) of 'HKEY_CURRENT_USER\Software\CompanyName\ProgName\'
to 'HKEY_LOCAL_MACHINE\Software\CompanyName\ProgName\'
So it's an entire "copy" that has to be made + sub keys should be copied too.
How can i achieve this? I'd like to combine this with the CRegKey class anyways.
Greetings
Jens

I think there is no readymade function to copy the regkeys recursively. 
Using the RegEnumKey () or RegEnumKeyEx () function, we get all the subkeys under a specific key.
Then using this function you can recursively traverse the registry subtree. For that you should know the tree traversal algorithm. Then while reading each key, make an identical copy of it under the destination keytree.
Hope this helps you. The only problem is the tree traversal. It will be a little bit difficult. Dont worry. Im searching some more easier method for copying the registry and will inform you, when i get it. 
Regards,
Jijo.

Use the following code. I got it from my friend - John AV, who is a registry expert. Okey. First be thorough with the code, make any changes if you need, then use it.
const static int nMaxValueNameSize = MAX_PATH;
const static int nMaxValueValueSize = 4096;
const static int nMaxClassSize = MAX_PATH;
const static int nMaxKeyNameSize = MAX_PATH;
BOOL CopyRegistryKey(HKEY hkRootFrom, const CString& strFromPath, HKEY hkRootTo, const CString& strToPath)
{
HKEY hkFrom;
LONG res = ::RegOpenKeyEx(hkRootFrom, strFromPath, 0, KEY_READ, &hkFrom);
if (ERROR_SUCCESS != res) {
return FALSE;
}
HKEY hkTo;
res = ::RegCreateKeyEx(hkRootTo, strToPath, 0, 0, REG_OPTION_NON_VOLATILE, KEY_WRITE, 0, &hkTo, 0);
if (ERROR_SUCCESS != res) {
::RegCloseKey(hkFrom);
return FALSE;
}
BOOL bRes = CopyKeys(hkFrom, hkTo) && CopyValues(hkFrom, hkTo);
::RegCloseKey(hkFrom);
::RegCloseKey(hkTo);
return bRes;
}
static BOOL CopyKeys(HKEY hkFrom, HKEY hkTo)
{
TCHAR lpstrName[nMaxKeyNameSize];
TCHAR lpstrClass[nMaxClassSize];
for (int i = 0;;i++) {
DWORD nNameSize = nMaxKeyNameSize;
DWORD nClassSize = nMaxClassSize;
LONG res = ::RegEnumKeyEx(hkFrom, i, lpstrName, &nNameSize, 0, lpstrClass, &nClassSize, 0);
if (ERROR_NO_MORE_ITEMS == res) {
break;
}
HKEY hkNew;
res = ::RegCreateKeyEx(hkTo, lpstrName, 0, lpstrClass, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, 0, &hkNew, 0); ;
if (ERROR_SUCCESS != res) {
return FALSE;
}
::RegCloseKey(hkNew);
BOOL bRes = CopyRegistryKey(hkFrom, lpstrName, hkTo, lpstrName);
if (! bRes) {
return FALSE;
}
}
return TRUE;
}
static BOOL CopyValues(HKEY hkFrom, HKEY hkTo)
{
TCHAR lpstrName[nMaxValueNameSize];
BYTE pValue[nMaxValueValueSize];
for (int i = 0;;i++) {
DWORD nType;
DWORD nNameSize = nMaxValueNameSize;
DWORD nValueSize = nMaxValueValueSize;
LONG res = ::RegEnumValue(hkFrom, i, lpstrName, &nNameSize, 0, &nType, pValue, &nValueSize);
if (ERROR_NO_MORE_ITEMS == res) {
break;
}
res = ::RegSetValueEx(hkTo, lpstrName, 0, nType, pValue, nValueSize);
if (ERROR_SUCCESS != res) {
return FALSE;
}
}
return TRUE;
}
Hope this helped you.
Regards,
Jijo.

Hi all,
Is there any way by which we can spy on the actual HTML being sent to the Browser Window.
Irrespective of the Browser we are using !
Do i have to write some driver to actually filter the HTML content ?
And it should be installed seamlessly (without having to set Ports manually)
Any suggestions will do
but please reply

For this you will have to run your code on the event a port opened in local and connected to remote 80. Remote port may be different if http port for that server is different eg:when ssl is installed.
However i dont feel there is any such event in windows.
Also may be you can try to run a netstat like application and moniter all the current connection and do wot you want. But this has the disadvantage that its like a polling mechanism.
greatest thing is to do wot others think you cant

i want something of this sort
http://www.codeproject.com/tools/htmlfilter.asp[^]
But it requires change to the proxy settings of browser window
can that be done automatically ?
Any suggestions ?

Hi,
what problem in this code.
//function call
m_hThread1 =(HANDLE)_beginthreadex (NULL,0,RequestProcess1,NULL,0,&m_dwThreadId1);
/fucntion
unsigned __stdcall CIFakerDlg::RequestProcess1(void *dummmy)
{
statements
}
i got the following error
error C2664: '_beginthreadex' : cannot convert parameter 3 from 'unsigned int (void *)' to 'unsigned int (__stdcall *)(void *)'
None of the functions with this name in scope match the target type
any one help tome. thanks in advance.

Make the RequestProcess1 as static function. Refer the SDK.
The _beginthread is declared as
unsigned long _beginthread( void( __cdecl *start_address )( void * ), unsigned stack_size, void *arglist );
