I have a com dll written in C++ which is used in asp applications. The dll contains only one com object. There are static (global to the process) data objects within this dll. Obviously, I only want to initialize these static objects when the dll is first loaded.
However, IIS seems to be reloading my dll everytime the com object is created and used in an asp page.

Load it inside global.asa into Application object?

Sorry, I am using this C++ com dll in asp projects, not ASP.NET projects.

I have a question.
This is the way I connect to the file through http
CHttpFile *pHttpFile = (CHttpFile *)InternetSession.OpenURL(LPTHD->from,INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_DONT_CACHE | INTERNET_FLAG_RELOAD);
Everything works fine, but in case the url does not exist I obtain the pointer to the html error page. How to check that the url hasn't been reached?
Please help

Check HTTP response code, must be 200 (200 OK) or 2xx I think

CHttpFile::QueryInfoStatusCode

I have noticed while trying to compile the MySQL++ library and from the errors returned that:
the reverse_iterator class has changed. According to the Microsoft documentation there has been a change in the STL library.
I was wondering if this change is limited to the Microsoft version of the STL or is it a change in the ANSI C++ STL?

I doubt there has been a change in ANSI C++ STL. Microsoft STL that ships with VC 7.0 is more compliant with the standard.

Yes, this one has hit me too some times ago. Microsoft made the change to make it ANSI compliant.

Hi all,
I'm still working on my switch statement program (from previous post)thanks to Joaquin my loop is working but for some reason my switch statements are not being activiated.
I've included a portion of my code, the switch statements continue for each letter a state begins with (d,f,g,h,i,k,etc)
Thanks,
Aaron

set the breakpoint on "switch (firstLetter)" line and check the value of firstLetter and secondLetter variables to see what values exactly are in them.

It appears as if nothing is happening because all of your output statements (cout and outState) in your switch statement are wrong.
Your doing this:
outState << inAbrev << " is " << "California" << endl;<br />
cout << inAbrev << " is " << "Alabama" << endl;
What this is doing is trying to output the input filestream which, of course, will output nothing.
If I read your homework right, you should be doing something like this:
outState << firstLetter << secondLetter << " is Alabama" << endl;

I have recently written a Service that parses a large XML file using MSXML, breaks the xml down in to fragments, and then calls a SQL Server stored procedure to process the xml fragment. As each call to the stored procedure is made memory is leaked. I have not been able to find any information concering this particular problem. It also appears that the MSXML objects are also leaking memory. The code fragment that follows is where the leak occurs. All pointer are SmartPointers and no dynamic allocation occurs in my code. Anybody have any ideas?
IXMLDOMNodeListPtr LogEntries = pXMLDocRoot->childNodes;
IXMLDOMElementPtr LogEntry = NULL;
for( int i = 0; i < LogEntries->length; ++i )
{
LogEntry = LogEntries->item[i];
if(LogEntry->nodeType == NODE_ELEMENT )
{
CString nodeName = (TCHAR*) LogEntry->nodeName;
CString spName;
spName.Format(_T("sp_%s"),nodeName);
CString xml = (TCHAR*)LogEntry->xml;
// execute this data
if (S_OK != m_AdoCmd.Execute_StoredProc(spName, xml))
{
CString errorMsg;
errorMsg.Format("Failed to execute stored procedure %s: error: %s", spName, m_AdoCmd.m_errorStr);
LogErrorMsg("ProcessXML: " + errorMsg);
return false;
}
}
LogEntry.Release();
}
LogEntries->reset();

I have to do this for Windows 95/98/Me/200/NT/XP:
I have the ID of a process(obtained with Process32First/Next) and I want to get the full path of the executable hwo started that process. In PROCESSENTRY32 the member szExeFile gives me only the name of the file but not the full path...
Thank you!
Best regards,
radu.

One solution is EnumProcessModules().
OpenProcess()
EnumProcessModules()
GetModuleFileNameEx()

That's what MSDN says:
Windows NT/2000/XP: Included in Windows NT 4.0 and later.
Windows 95/98/Me: Unsupported.
So it's not a solution for 95/98/Me...

I'm working on a project which will need to read/write xls files(Microsoft Excel documents), hmm... I don't have any idea how xls files are serialized, is there any library for doing this? Oh is there any articles/documentation about this topic? Thanks a lot.

Ok im trying to count the characters that i have loaded into a buffer i have set up the following function
void countchars(char *buffer, int *count)
/*Counts the number of characters in the text file */
{
int i,counter;
char cdata;
count['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'];
do
{
{ for(cdata='A';cdata<='Z';cdata++)
if(buffer[i]==counter[count])
{
count++;
}
i++;
}
}while(buffer[i]!=EOF);
}
I am calling this function using the following code:
countchars(buffer,cdata);
printf("\nDistribution of letters in %s is:",fname);
for (c='A';c<='Z';c++)
{
N=cdata[c]+cdata[tolower(c)];
printf("\n'%c' %4d: ",c,N);
for (i=0;i
