I am aware that it is a horrible thing to do.
But for this example I highly doubt it is messing with anything I am doing.
I need to be able to get the Certificate Chain so I can plug it into an Adobe app.

I don't know why you feel the need to pick apart my wording.
The code complies, and runs, but I am not getting the expected results.

The while loop is failing and going to the end of the program. So it isn't picking up the certificates.

#include <iostream>
#include "windows.h"
#include "Wincrypt.h"
#pragma comment(lib, "Crypt32") 

int main()
{
	PCCERT_CHAIN_CONTEXT chainContext;
	HCERTSTORE certStore = "MY";
	DWORD dwCertEncodingType = X509_ASN_ENCODING;
	DWORD dwFindFlags = CERT_CHAIN_FIND_BY_ISSUER_NO_KEY_FLAG;
	DWORD dwFindType = CERT_CHAIN_FIND_BY_ISSUER;
	const void *pvFindPara = "MyIssuer";
	PCCERT_CHAIN_CONTEXT pPrevChainContext = NULL;

	while (chainContext = CertFindChainInStore(certStore,
		dwCertEncodingType,
		dwFindFlags,
		dwFindType,
		pvFindPara,
		pPrevChainContext))
	{
		printf((const char*)chainContext);
	}

	system("PAUSE");
	return 0;
}

Yes David you are right, that is the correct link.

Have you seen this?

That IS the first time I have seen that. It still doesn't iterate through any on my certificates though.
I really am a little confused...Every example I have tried to implement fails at the while loop.

mypicturefaded,

The code you have shown is looking for certificates in the certificate store named "MY" signed by "MyIssuer". Are you sure that you have certificates that match this criteria?

You can check by following the instrustions below.

How to: View Certificates with the MMC Snap-in[^]

You should also note that the default certificate chain is HCCE_CURRENT_USER. If you need to enumerate certificates in the local system account you will need to use the CertGetCertificateChain Function[^] with the hChainEngine argument set as HCCE_LOCAL_MACHINE.

Best Wishes,
-David Delaune

In a function OnSysCommand() check a parameter for equality SC_MAXIMIZE. Then wrote a code which works perfectly in OnSizing(), but GetWindowRect() and ScreenToClient() return the rectangle of that window which was to maximization. What is a problem in?

do you want ScreenToClient Information in maximize mode or before maximize

Hi all,

I have many compilation errors in my solutions and the type of errors are very different.

I am developing an MFC dialog application with visual studio 2005 and the follwoing is one of my work and with eash file I am adding the errors generated with each file.

// ( RulesMatching.h )

#ifndef RULESMATCHING_HEADER_ID
#define RULESMATCHING_HEADER_ID

#include "PatternMatching.h"

class CRulesMatching
{
public:
CRulesMatching();
int MatchRule(CString,int);

CPatternMatching OPM2; // create object OPM2 from the class
}

#endif

// ( RulesMatching.cpp )

#include "stdafx.h"
#include "RulesMatching.h"
#include "afxdb.h"
#include "odbcinst.h"

CRulesMatching::CRulesMatching()
{

}

int CRulesMatching::MatchRule(CString Str, int Cnum)
{

CDatabase database4;
CString SqlRulePattern;

CString sDriver("MICROSOFT ACCESS DRIVER (*.mdb)");
CString sDsn;
CString ssDSN("ODBC;DRIVER={%s};DSN='';DBQ=%s");
CString sFile("d:\\works\\ReadDB\\ASU.mdb");

sDsn.Format(ssDSN, sDriver, sFile);

database4.Open(NULL,false,false,sDsn);

CRecordset recset2( &database4 );

SqlRulePattern= "SELECT * from Patterns where CNum="+Cnum ;

recset2.Open(CRecordset::forwardOnly,SqlRulePattern,CRecordset::readOnly);
int Result2;
CString RContextNum,RRuleNum,RPatternNum,RPatternValue,RPatternContent;
CString BestRContextNum,BestRRuleNum,BestRPatternNum;

while(!recset2.IsEOF())
{
recset2.GetFieldValue(_T("CNum"),RContextNum);
recset2.GetFieldValue(_T("RNum"),RRuleNum);
recset2.GetFieldValue(_T("PNum"),RPatternNum);
recset2.GetFieldValue(_T("PValue"),RPatternValue);
recset2.GetFieldValue(_T("PContent"),RPatternContent);

Result2 = OPM2.MatchPattern(Str,RPatternContent);
if (Result2==1)
{
BestRContextNum = RContextNum;
BestRRuleNum = RRuleNum;
BestRPatternNum = RPatternNum;
recset2.MoveNext();
}

else
{
recset2.MoveNext();
}

}// while() closing

int i = _ttoi(BestRRuleNum);

return i ;

}

WHEN I COMPILE THE PREVIOUS ( .cpp file ) I HAD THESE ERRORS:

I am sorry for this long thread but I worked for two days to make the solution working and I can't and I checked every missing semicolon or bracket and there is no somthing missing..

Please anyone can help me let me know and I appreciate any type of helping.

You forgot the ; after the declaration of CRulesMatching in your RulesMatching.h.

always concentrate on the first error message first, solving it may reduce the list dramatically.

hello all, i have a problem need your help...

I'm with you so far.

Are you talking about using GetItemText() or GetItem() in response to a LVN_ITEMCHANGED message?

yiyinkuang wrote:

This is unclear in so many ways.

yiyinkuang27-Aug-09 3:46

yes，，i try to use GetItemText store item text ,,but GetItemText will trigger the item text change

Store it where, in the list control or some data structure?

yiyinkuang wrote:

Nonsense (assuming you are referring to the LVN_ITEMCHANGED message). That would only happen if you used SetItemText().

yiyinkuang27-Aug-09 4:25

27-Aug-09 4:25

thank you,,use GetItemText will send LVN_GETDISPINFO,,and function OnGetdispinfoList will change the item text

(assuming I understand what you want)

If you have a "virtual" list ctrl (CListBox or CListCtrl?), then you should have an underlying data structure somewhere that holds the data that is displayed by the list.

In you derived list ctrl control, there should be a method to display each item individually something like DrawItem); usually, it's in that method that you fetch the data from your data structure and "format" it correctly to be displayed in the list ctrl.

This signature was proudly tested on animals.
