ni ada contoh prog yang saya ambik kat internet untuk panggil cert store dan listkan dlm web page ,and saya cuba compilekan,and ada error muncul kat bhg ini:

#define _WIN32_WINNT 0x0400
#include <windows.h>
#include <jni.h>
#include <wincrypt.h>
#define MY_ENCODING_TYPE (PKCS_7_ASN_ENCODING | X509_ASN_ENCODING)

#include "Testapp.h"

saya cuba surf byk tempat tapi agak blur so mintak tolong sgt nie
tlg jelas kan yer.



yang kat bwh ni permulaan prog code dia

import java.awt.*;
import java.io.*;
import java.lang.*;
import java.applet.*;

public class Testapp extends Applet {



String ret=null;


public void init(){




System.out.println("in init");

loaddll();

}

public void loaddll(){


System.out.println("before loading DLL");
System.loadLibrary("Msgimpl");
System.out.println("After loading DLL");

}

private native String crypto(String store);


public void paint(Graphics g) {
g.setColor(Color.blue);
g.setColor(Color.magenta);



g.drawString("call before native function", 25, 25);


ret=crypto("My");


g.drawString(ret, 25, 50);

g.drawString("Finally", 25, 75);

}

#define _WIN32_WINNT 0x0400
#include <windows.h>
#include <jni.h>
#include <wincrypt.h>
#define MY_ENCODING_TYPE (PKCS_7_ASN_ENCODING | X509_ASN_ENCODING)

#include "Testapp.h"

}



BOOL APIENTRY DllMain(HANDLE hModule,
DWORD dwReason, void** lpReserved) {
return TRUE;
}

JNIEXPORT jstring JNICALL
Java_Testapp_crypto(JNIEnv * jEnv,jobject obj,jstring jstore) {
HCRYPTPROV hProv;
BOOL bResult;
HCERTSTORE hStoreHandle = NULL;
PCCERT_CONTEXT pCertContext = NULL;
char pszNameString[256];
CRYPT_KEY_PROV_INFO *pCryptKeyProvInfo;
DWORD dwPropId=0;
DWORD cbData;
const char *msg;

jstring jstr;
msg = (*jEnv)->GetStringUTFChars(jEnv, jstore,0);

//printf("Before context\n");

if (hStoreHandle = CertOpenSystemStore(NULL,msg))
{
printf("The %s store has been opened. \n", msg);
}
else
{
printf("The store was not opened.\n");
exit(1);
}

while(pCertContext= CertEnumCertificatesInStore(hStoreHandle,pCertCont ext))
// on the first call to the function,
// this parameter is NULL
// on all subsequent calls,
// this parameter is the last pointer
// returned by the function
{


if(CertGetNameString(pCertContext,CERT_NAME_FRIEND LY_DISPLAY_TYPE,0,NULL,pszNameString,1000))
{
printf("\nCertificate for %s \n",pszNameString);
}
else
{
printf("\nGetNameFailed\n");
}




}//main while
return (*jEnv)->NewStringUTF(jEnv, pszNameString);
//(*jEnv)->ReleaseStringUTFChars(jEnv, jstore,msg);




if (!CertCloseStore(hStoreHandle,0))
{
//printf("Failed CertCloseStore\n");
exit(1);
}


//printf("After context\n");




}




thank u in advance

well... depend on my knowledge of C and JAVA ( :P ), starting from line #define _WIN32_WINNT 0x0400 until the end, are C source code, not Java.

Since you did not provide the URL of where you the these codes, we have difficulty to trace the errors.

Try...

From the codes, it seems like divide into two parts. The Java applet and C. Try to save all codes infront line #define _WIN32_WINNT 0x0400 to filename Testapp.h

Then, create a C source code file and paste all codes begin from #define _WIN32_WINNT 0x0400 until then end into it, compile and run.

I am sure there is/are still error(s)... } after #include "Testapp.h" seems like reduntant...

Just my little ideas. Good luck!

fuuu, complicatednye source code yang ko kasik nih. aku suggest better carik lain la, aku pon pening tengok. ape yang ko nak buat actually, nak buat authentication certificate untuk secure transaction ke?

Your trying to develop some hybrid application with source code that is way to complex for a beginner. I suggest that you start simple and stick to a single language.

I think you need to learn the fundamentals of the language before you can even think of tackling projects like this.

I guess he/she just simply copy & paste the code that he/she found and think suitable...

hmm, ni mesti assignment ni, curik source code kat internet, skali nak run error! hahaha. well, been there, done that.

ahaks maybe tepat tekaan kamu masterix
