normally u should use CInternetSession.
if socket, does the server side send the page and allow u connect to the socket pipe?

Hello to everybody,
I have added wit the wizard 2 methods for my ActiveX :
PutNumber (ULONG uNumber)
PutData (BYTE* pData )
I compile the application and I run the ActiveX to test it with the Container of Visual Studio. I have set two stop points in both methods. When I invoke the first method, it works well. It goes inside the function but when I try the second one it doesn't work...I think it is a problem that pData is a pointer cause I have created several methods to test it and it doesn't work only when I use a pointer.
Please Help
Thanks
Javi

Check out the data type converion ur using, coz u might be passing some other datatype n while using pointers always chekout type conversion.

hi
i wrote a function which conjnects me to an online mysql database from my app. when i use the function from a win32 console application, all is well. when i port the same function to my mfc application, it gives all sorts of linker errors saying that there's a conflict between libc.lib and mysql++.lib. putting libc.lib or libcmt.dll in the ignore library list from the settings does not help.
anybody have any idea ? you guys ever used mysql++ from an mfc application ? if yes please give me the project settings and a few snippets ....
thanks in advance.

Did you compile MySQL++ yourself, or download a precompiled version? If you compiled the latest version yourself, and you used the provided .vcproj, it should have built with the Multithreaded DLL version of the C run-time.
The default configuration for a Win32 Console Application is to use the single-threaded static library CRT. The default for an MFC application is to use the multithreaded DLL. You can't mix-and-match within an application - if you're going to use the MFC DLL you must use the CRT DLL.
The home page[^] suggests that before version 1.7.16, the single-threaded static CRT was used.
Stability. What an interesting concept. -- Chris Maunder

Thanks for the help Mike!
i downloaded my mysql++ from this website only, i downloaded the precompiled "ancient" version because i have visual studio 6 with service pack 6. my mysql++ version is 1.7.1 the page says that newer versions won't build with vc++6..what do u suggest i should do ? Can i compile the lib with borland c++ and use it in my vc++ projects ? or is it absolutely necessary for me to upgrade..?

I use pipes with CreateProcess(), but my code works well on win98 and doesn't work on XP.
only special code for XP in my app looks like:
=========================
void*psd=0;
LPSECURITY_ATTRIBUTES psa=0;
DWORD bNT=(GetVersion()<0x80000000)?1 ;
if(bNT)
{
psd=::GlobalAlloc(GPTR,SECURITY_DESCRIPTOR_MIN_LENGTH);
::InitializeSecurityDescriptor(psd,SECURITY_DESCRIPTOR_REVISION);
::SetSecurityDescriptorDacl(psd,-1,0,0);
psa=(LPSECURITY_ATTRIBUTES)::GlobalAlloc(GPTR,sizeof(SECURITY_ATTRIBUTES));
psa->nLength=sizeof(SECURITY_ATTRIBUTES);
psa->lpSecurityDescriptor=psd;
psa->bInheritHandle=1;
}
const BOOL bOK=CreateProcess(0,pszCmdLine,psa,0,1,0,0,0,&si,&pi);
//======================================
do i need more special code for XP?
thx

Define "doesn't work." Are you getting a compiler/linker error, a runtime error, a fired assertion, or a thrown exception?

void*psd=0;
Shouldn't this be:
PSECURITY_DESCRIPTOR psd = 0; includeh10 wrote:
::SetSecurityDescriptorDacl(psd,-1,0,0);
I'm not sure of the behavior of this function when bDaclPresent is neither 0 nor 1.

What happens if you call this function with lpProcessAttributes set to NULL?

"doesn't work" means that messages do not exchange between pipes at all, the dos app respones for command in CreateProcess(), after that, communication stops.
i will test ur suggestion.

lpProcessAttributes!=0 is commented by docs, which say it is special for NT.
if lpProcessAttributes=NULL, it is the same (works on Win98 but not on XP).
I had many apps which use code above and work well on all platform - but they are Windows apps, not DOS one.
i can not find reason why the code has trouble on DOS app.
by the way, PSECURITY_DESCRIPTOR is just void*, some people define many sick definitions.
thx

I see it saying that the handle cannot be inherited and the process gets a default security descriptor. In any case, ...

Which should indicate to you that the following code has no bearing on the problem:
DWORD bNT=(GetVersion()<0x80000000)?1:0;
if(bNT)
{
psd=::GlobalAlloc(GPTR,SECURITY_DESCRIPTOR_MIN_LENGTH);
::InitializeSecurityDescriptor(psd,SECURITY_DESCRIPTOR_REVISION);
::SetSecurityDescriptorDacl(psd,-1,0,0);
psa=(LPSECURITY_ATTRIBUTES)::GlobalAlloc(GPTR,sizeof(SECURITY_ATTRIBUTES));
psa->nLength=sizeof(SECURITY_ATTRIBUTES);
psa->lpSecurityDescriptor=psd;
psa->bInheritHandle=1;
}Remove this and the problem becomes more refined. By removing unnecessary code, you'll eventually get down to just the few lines that are necessary to demonstrate the problem.

Fair enough, but it would make more sense to others if PSECURITY_DESCRIPTOR were used. There's also the (small) possibility that it may change from void* in the future.

Hello!
I need to interface my VC++ application with Outlook Express 6.0.
I'd need:
- access to email messages in Outlook folders,
- eventually, copy email messages in other files (with EML format and other
place);
- make email messages and send them with Outlook Express (Outbok).
I found a very useful sample on codeproject.com (made by Pablo Yabo), about using IStoreFolder and IStoreNamespace to manage Outlook Exp folders.
But ... what about outgoing emails? The sample can just make a "streamed" file, that's not sent by Outlook Express.
Do I need to use IMimeMessage interface?
Is there any sample that show the use of IMimeMessage interface?
Thank you in advance!
Chiara
