I'm trying to write a pro-forma ISAPI extension in an attempt to better understand IIS. I have the following code for the exension:
#include <httpext.h>
#include <cstring>
#include <cstdio>
#include <fstream>
#include <iostream>
#include <windows.h>
BOOL WINAPI GetExtensionVersion(HSE_VERSION_INFO * versionInfo)
{
versionInfo->dwExtensionVersion = HSE_VERSION;
strcpy_s( versionInfo->lpszExtensionDesc, "ISAPIExtension.dll");
return TRUE;
}
DWORD WINAPI HttpExtensionProc(EXTENSION_CONTROL_BLOCK* ecb)
{
char * msg = "<html><head/><body>Hello world</body></html>";
DWORD msg_length = strlen(msg) * sizeof(char);
DWORD sent_length = msg_length;
std::cout << sent_length;
auto result = ecb->WriteClient(ecb->ConnID, msg, &sent_length, 0);
if (!result || sent_length != msg_length)
{
std::fstream output("errors.txt");
output << "Could not write to client. Last error was " << GetLastError();
output.flush();
output.close();
return HSE_STATUS_ERROR;
}
std::cout << sent_length;
return HSE_STATUS_SUCCESS;
}
IIS Express responds with HTTP 200, but zero bytes were sent back to the client. Is anything in the above wrong? For reference, this is my applicationhost.config:
<?xml version="1.0" encoding="UTF-8"?>

Adding a Content-Type header fixes the issue:
DWORD WINAPI HttpExtensionProc(EXTENSION_CONTROL_BLOCK* ecb)
{
char msg [] = "<html><head/><body>Hello world</body></html>";
DWORD msg_length = strlen(msg);
DWORD sent_length = msg_length;
HSE_SEND_HEADER_EX_INFO HeaderExInfo;
HeaderExInfo.pszStatus = "200 OK";
HeaderExInfo.pszHeader = "Content-type: text/html\r\n\r\n";
HeaderExInfo.cchStatus = strlen(HeaderExInfo.pszStatus);
HeaderExInfo.cchHeader = strlen(HeaderExInfo.pszHeader);
HeaderExInfo.fKeepConn = FALSE;
ecb->ServerSupportFunction(ecb->ConnID, HSE_REQ_SEND_RESPONSE_HEADER_EX, &HeaderExInfo, NULL, NULL);
auto result = ecb->WriteClient(ecb->ConnID, msg, &sent_length, 0);
if (!result || sent_length != msg_length)
{
return HSE_STATUS_ERROR;
}
return HSE_STATUS_SUCCESS;
}
Microsoft has posted a similar ISAPI extension sample on their GitHub account: https://github.com/Microsoft/Windows-classic-samples/tree/master/Samples/Win7Samples/web/iis/extensions/simple

I have a bash script as follows:
foldername=camera_calibration_$(date +"%m-%d-%Y")
im_name="/cam0"
roslaunch image_pub cam_calibration.launch foldername:=$foldername image_name:=$im_name
My roslaunch script is as follows:
<launch>
<arg name = "foldername" default="camera_calibration" />
<arg name = "image_name" default="/cam1" />
<param name="foldername" type="string" value="$(arg foldername)" />
<param name="image_name" type="string" value="$(arg image_name)" />
<param name="size_name" type="string" value="12x8" />
<param name="square" type="string" value="0.05" />
<node name="im_pub_sub_node" pkg="image_pub" type="im_pub_sub" output="screen"/>
<node name="cameracalibrator_node" pkg="camera_calibration" type="cameracalibrator.py" output="screen"/>
</launch>
My C++ script (im_pub_sub.cpp) as follows:
int main(int argc, char** argv) {
std::string foldername;
std::string imagename;
std::string si_name;
ros::param::get("/size_name", si_name);
ros::param::get("/foldername", foldername);
ros::param::get("/image_name", imagename);
std::cout<<imagename<<std::endl;
std::cout<<foldername<<std::endl;
std::cout<<si_name<<std::endl;
std::cout<<"hi"<<std::endl;
}
When I launch it I only get "hi" print on my console but not foldername, image_name defined from bash and si_name param defined in launch file. It prints empty like nothing for other params defined.
I can get these params printed in my python script, but I am unable to do the same using c++. This is completely "weird".
Can anyone please let me know what is wrong in my syntax?
I got it. That's because you can't get rosparams from launch file until rosnode initilaization and node Nodehandler is being defined.
int main(int argc, char** argv) {
ros::init(argc, argv, "im_sub_pub_cpp");
ros::NodeHandle nh_;
std::string foldername;
std::string imagename;
std::string si_name;
ros::param::get("/size_name", si_name);
ros::param::get("/foldername", foldername);
ros::param::get("/image_name", imagename);
std::cout<<imagename<<std::endl;
std::cout<<foldername<<std::endl;
std::cout<<si_name<<std::endl;
std::cout<<"hi"<<std::endl;
}
Then this works.
I am learning by myself and i want to know how to use precompiled headers in my console app. I have read a lot of guides, it seems i am doind everything right but i still get error.
I use visual studio 2019. So i have main.cpp file with code that uses and libraries i would like to be precompiled. I have created a file called stdafx.h and have included all libraries there. Then i created stdafx.cpp which only includes stdafx.h. In project properties for stdafx.cpp precompiler headers are /Yc and for main it is /Yu.
stdafx.h:
#include <iostream>
#include <cmath>
stdafx.cpp:
#include "stdafx.h"
main.cpp:
#include "stdafx.h"
using namespace std;
double getInfoFromUser()
{
double info;
cin >> info;
return info;
}
double computeSqrtDiscriminant(double A, double B, double C)
{
double i{ sqrt(pow(B, 2) - 4 * A * C) };
return i;
}
double computeX1(double A, double B, double SqrtDiscriminant)
{
double X1{ (-B + SqrtDiscriminant) / (2 * A) };
return X1;
}
double computeX2(double A, double B, double SqrtDiscriminant)
{
double X2{ (-B - SqrtDiscriminant) / (2 * A) };
return X2;
}
void computePoint1(double X1, double K, double M)
{
double Y{ X1 * K + M };
cout << "Первая точка пересечения:[" << X1 << "," << Y << "]" << endl;
}
void computePoint2(double X2, double K, double M)
{
double Y{ X2 * K + M };
cout << "Вторая точка пересечения:[" << X2 << "," << Y << "]";
}
double equateX(double B, double K)
{
double NewB{ B - K };
return NewB;
}
double equateC(double C, double M)
{
double NewC{ C - M };
return NewC;
}
int main()
{
setlocale(LC_ALL, "rus");
cout << "Введите уравнение параболы (aх^2+bx+c=0):" << endl;
cout << "Введите a:";
double A{ getInfoFromUser() };
cout << "Введите b:";
double B{ getInfoFromUser() };
cout << "Введите c:";
double C{ getInfoFromUser() };
cout << "Введите уравнение прямой (Kx+m)" << endl;
cout << "Введите k:";
double K{ getInfoFromUser() };
cout << "Введите m:";
double M{ getInfoFromUser() };
B = equateX(B, K);
C = equateC(C, M);
double SqrtDiscriminant = computeSqrtDiscriminant(A, B, C);
double X1{ computeX1(A, B, SqrtDiscriminant) };
double X2{ computeX2(A, B, SqrtDiscriminant) };
computePoint1(X1, K, M);
if (X1 != X2)
{
computePoint2(X2, K, M);
}
return 0;
}
main.cpp compiles greatly even without precompiled headers, but i want to learn how to use them. If compiled with precompiled headers i get theese two errors:
error : Element has an invalid value of "/Yu".
error MSB6011: в задачу Microsoft.Build.CPPTasks.CL переданы недопустимые параметры.(i am from Ukraine so i use Russian localization).

So the problem was that i was typing manually the /Yu and /Yc in the file`s properties, although there is dropbox-box in the upper right corner. If you use the dropbox the problem fade away.
The translation unit for the precompiled header needs to use /Yc instead of /Yu.
In your example you need to enable that setting for stdafx.cpp
In the GUI this is done like this:
1. Right click the file in the Solution explorer
2. Select "Properties"
3. Make sure that "Configuration" at the top is set to "All Configurations" and the Plaform setting is what you want it to be
4. Go to the "C/C++ -> Precompiled Headers" menu on the right
5. Change the "Precompiled Header" setting to "Create (/YC)"
The values in the *.vcxproj file should be
<Project DefaultTargets="Build" ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<!-- ... -->
<ItemDefinitionGroup>

The XSD file:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="urn:BookStore"
xmlns:bks="urn:BookStore">
<xsd:complexType name="BookForm">
<xsd:sequence>
<xsd:element name="author" type="xsd:string"/>
<xsd:element name="title" type="xsd:string"/>
<xsd:element name="genre" type="xsd:string"/>
<xsd:element name="price" type="xsd:float" />
<xsd:element name="pub_date" type="xsd:date" />
<xsd:element name="review" type="xsd:string"/>
</xsd:sequence>
<xsd:attribute name="id" type="xsd:string"/>
</xsd:complexType>
<xsd:element name="books"> <!-- not mapped to named typed! -->
<xsd:complexType >
<xsd:sequence>
<xsd:element name="book"
type="bks:BookForm"
minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
Reading the library (reading only two fields)
#include <iostream>
#include "books.h"
using namespace std;
using namespace BookStore;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
try {
// what do I do here since BooksForm is not defined now and XSD file
// doesn't map it to the root element of XML?
auto_ptr<BooksForm> bookBank (books( "books.xml" ));
for (BooksForm::book_const_iterator i = (bookBank->book().begin());
i != bookBank->book().end();
++i)
{
cout << "Author is '" << i->author() << "'' " << endl;
cout << "Title is '" << i->title() << "'' " << endl;
cout << endl;
}
}
catch (const xml_schema::exception& e)
{
cerr << e << endl;
return 1;
}
return a.exec();
}
So this code works if XSD file is in format as in this post but I want to know how can I read the XML if the XSD file is in above format. I need to do this in this small demo so I can resolve the similar situation in another larger and more complex XML file which is a given thing.
I am trying to build a server application using gsoap 2.8.17. I've created a header file with service function prototype and a result record definition
testserver.h:
#ifndef TESTSERVER_H
#define TESTSERVER_H
#include <string>
//gsoap ns service name: TestServer
//gsoap ns service namespace: http://mycomp:8080/TestServer.wsdl
//gsoap ns service location: http://mycomp:8080/TestServer.cgi
//gsoap ns schema namespace: urn:TestServer
class Record
{
public:
int id;
std::string name;
std::string address;
double param1;
};
int ns__GetRecord(int id, Record* result);
#endif
Then I've invoked the gSOAP RPC compiler:
soapcpp2.exe testserver.h
The compiler produced the following files:
soapC.cpp
soapClient.cpp
soapClientLib.cpp
soapServer.cpp
soapServerLib.cpp
soapH.h
soapStub.h
TestServer.h
TestServer.nsmap
TestServer.wsdl
TestServer.GetRecord.req.xml
TestServer.GetRecord.res.xml
ns.xsd

As documentation recommends I added soapServerLib.cpp to my project, but the C++ Builder 2010 compiler produces errors:
[BCC32 Error] soapC.cpp(1611): E2238 Multiple declaration for 'ns__GetRecord(soap *,int,Record *)'
[BCC32 Error] soapStub.h(224): E2344 Earlier declaration of 'ns__GetRecord(soap *,int,Record *)'
[BCC32 Error] soapC.cpp(1611): E2303 Type name expected
[BCC32 Error] soapC.cpp(1611): E2379 Statement missing ;
[BCC32 Error] soapC.cpp(1717): E2379 Statement missing ;
soapStub.h(224):
SOAP_FMAC5 int SOAP_FMAC6 ns__GetRecord(struct soap*, int id, Record *result);
soapC.cpp(1598-1619):
SOAP_FMAC1 struct ns__GetRecord * SOAP_FMAC2 soap_instantiate_ns__GetRecord(struct soap *soap, int n, const char *type, const char *arrayType, size_t *size)
{
(void)type; (void)arrayType; /* appease -Wall -Werror */
DBGLOG(TEST, SOAP_MESSAGE(fdebug, "soap_instantiate_ns__GetRecord(%d, %s, %s)\n", n, type?type:"", arrayType?arrayType:""));
struct soap_clist *cp = soap_link(soap, NULL, SOAP_TYPE_ns__GetRecord, n, soap_fdelete);
if (!cp)
return NULL;
if (n < 0)
{ cp->ptr = (void*)SOAP_NEW(struct ns__GetRecord);
if (size)
*size = sizeof(struct ns__GetRecord);
}
else
{ cp->ptr = (void*)SOAP_NEW_ARRAY(struct ns__GetRecord, n); // <<<-- error here
if (size)
*size = n * sizeof(struct ns__GetRecord);
}
DBGLOG(TEST, SOAP_MESSAGE(fdebug, "Instantiated location=%p\n", cp->ptr));
if (!cp->ptr)
soap->error = SOAP_EOM;
return (struct ns__GetRecord*)cp->ptr;
}
Why is ns__GetRecord interpreted as a structure while it's a function name? What should I fix in my TestServer.h to make soapcpp2.exe produce a compilable code ?
The only solution I found is to remove the soap_instantiate_ns__GetRecord function body.
SOAP_FMAC1 struct ns__GetRecord * SOAP_FMAC2 soap_instantiate_ns__GetRecord(struct
soap *soap, int n, const char *type, const char *arrayType, size_t *size)
{
return NULL;
}
Then the server code compiles and works fine.
