Hi all,
I has been created one MFC extension dll called SRecordset.dll,which has been one .h file and one .cpp file
my dll .h file..
#pragma once<br />
#include afxdb.h<br />
<br />
<br />
class AFX_EXT_CLASS SRecordset : public CObject<br />
{<br />
DECLARE_SERIAL(SRecordset)<br />
<br />
<br />
public:<br />
SRecordset(void);<br />
<br />
public:<br />
~SRecordset(void);<br />
<br />
protected:<br />
CStringArray saDataContainer;<br />
short iNumFldCount;<br />
long iNumRec;<br />
int iRecCount;<br />
int iTotalSize;<br />
int iRecordState;<br />
int iLocalIndex;<br />
public:<br />
BOOL SSOpen(CDatabase &dbConnectedObj,CString sQuery);<br />
BOOL SSIsOpen(void);<br />
void SSClose(void);<br />
public:<br />
BOOL SSIsBOF(void);<br />
BOOL SSIsEOF(void);<br />
public:<br />
void SSGetFieldValue(int iIndex,CString &FldValue);<br />
short SSGetFieldCount(void);<br />
long SSGetRecordCount(void);<br />
long SSGetCurrentRecordCount(void);<br />
public:<br />
void SSMoveNext(void);<br />
void SSMovePrevious(void);<br />
void SSMoveFirst(void);<br />
void SSMoveLast(void);<br />
public:<br />
virtual void Serialize(CArchive& ar);<br />
};
I has been created my dll successfully. But, it won't support to the client application,it will be thrown only one linker error, when i call rather the SSOpen(CDatabase &dbConnectedObj,CString sQuery) function only, not other function calls from my above the class during the runtime.
Here the part of code from my client app...
void CtestingDlg::OnBnClickedOk()<br />
{<br />
<br />
<br />
CDatabase db;<br />
CString sIp,sDb,sPwd,sConn,sPort,sUn;<br />
sIp="192.168.2.17";<br />
sPort="5432";<br />
sPwd="fasp";<br />
<br />
<br />
try<br />
{<br />
sConn = "DRIVER={PostgreSQL ANSI};SERVER=" + sIp + ";port=" +<br />
sPort + ";DATABASE=" + sPwd + ";UID=" + sPwd + "WD=" + sPwd + ";";<br />
db.OpenEx(sConn);<br />
AfxMessageBox("Success");<br />
}<br />
catch(CDBException *e)<br />
{<br />
MessageBox("Database Connection Refused."+e->m_strError,"DataBase<br />
Connection Error",MB_OK|MB_ICONERROR);<br />
e->Delete();<br />
<br />
}<br />
<br />
<br />
SRecordset set1;<br />
<br />
set1.SSOpen(db,"select name from master;");<br />
set1.SSGetFieldCount();<br />
set1.SSGetRecordCount();<br />
set1.SSClose();<br />
<br />
OnOK();<br />
}
where set1.SSOpen(db,"select name from master;"); is the problem
Error is.....
testingDlg.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: int __thiscall SRecordset::SSOpen(class CDatabase &,class ATL::CStringT > >)" (__imp_?SSOpen@SRecordset@@QAEHAAVCDatabase@@V?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@@Z) referenced in function __catch$?OnBnClickedOk@CtestingDlg@@QAEXXZ$0
please note that my class is derived from CObject class meanwhile CDatabase is also derived from CObject class...i think may be this is the reason for my problem?
please help me!

Did you provide a body for this function ?

|

this is my function body..
IMPLEMENT_SERIAL(SRecordset,CObject,VERSIONABLE_SCHEMA | 2)<br />
<br />
BOOL SRecordset::SSOpen(CDatabase &dbConnectedObj,CString sQuery) <br />
{<br />
if(!dbConnectedObj.IsOpen())<br />
return FALSE;<br />
<br />
CRecordset rsObject(&dbConnectedObj);<br />
<br />
CString sValue;<br />
<br />
if(!rsObject.Open(AFX_DB_USE_DEFAULT_TYPE,sQuery)) <br />
return FALSE;<br />
<br />
iNumFldCount = rsObject.GetODBCFieldCount(); <br />
<br />
iNumRec = 0; <br />
<br />
while(!rsObject.IsEOF())<br />
{<br />
rsObject.MoveNext(); <br />
iNumRec++; <br />
}<br />
<br />
iTotalSize = iNumFldCount * iNumRec; <br />
<br />
saDataContainer.SetSize(iTotalSize); <br />
<br />
rsObject.MoveFirst();<br />
<br />
iRecCount = 0;<br />
<br />

{<br />
for(int ic=0; ic < iNumFldCount; ic++)<br />
{<br />
sValue = "";<br />
rsObject.GetFieldValue(ic,sValue);<br />
saDataContainer[iRecCount] = sValue; <br />
iRecCount++;<br />
}<br />
<br />
rsObject.MoveNext();<br />
}<br />
<br />
rsObject.Close();<br />
dbConnectedObj.Close();<br />
return TRUE;<br />
<br />
}

I am not sure: check that for both projects you are using the same unicode settings (unicode needs to be defined for both or for none of them). Maybe it is due to the fact that for one of the project, CString will be defined as CStringA (non unicode) and for the other, CString will be defined as CStringW (unicode). Thus, a linker error.
But I'm not sure at all.

ok fine you are correct my dll is unicode character set but my client is non unicode set,now its working fine. thank you.

I am attempting to POST to a HTTPS server all is apparently S_OK but I get a STATUS code returned of 12019 and no ResposeText! Is this because MS XMLHTTP40 does not cater for certificates? If so any idea how I can POST my XML to the HTTPS server and successfully receive responses???
|
|
|
|

I have added:
hr = pXMLHTTPReq->setOption( (MSXML2::SERVERXMLHTTP_OPTION)2, 13056 );
and now get the following response:
<code>STATUS CODE: 405
Response Text: <HTML><HEAD><TITLE>Method Not Allowed</TITLE></HEAD><BODY><H1>Method Not Allowed</H1>An error occurred.</BODY></HTML>
All Response Headers: Server: Sun-ONE-Web-Server/6.1 Date: Thu, 10 May 2007 10:10:58 GMT Content-length: 124 Content-type: text/HTML Allow: Head, GET Connection: close</code>
I would very much appreciate if anyone could shed any light on how to resolve this.

This is getting rather anoying!
I have changed:
hr = pXMLHTTPReq->open( "POST", bstrURL, VARIANT_FALSE );
to:
hr = pXMLHTTPReq->open( "post", bstrURL, VARIANT_FALSE );
This changes the returned STATUS code from 405 "Method Not Implemented" to 501 and the resposeText I now get is: "This server does not implement the requested method". How else other than using the "post" method do we SEND XML to a HTTPS service?

How are you trying to close it?

Can you show code snippet that you got error?
|

yes this is the code
BOOL CMyConnCustomInstall::OnCUSTInstall()
{
int MyConnecCheck = 0, ChatCheck = 0, PwdMgr = 0, Response = 0, nStatus = 0;
int EKMyConnDLSuccess = 0, EKChatDLSuccess = 0, EKPwdMgrDLSuccess = 0;
CFileOperation *fileOpr = new CFileOperation();
m_Downloading = 1;
BeginWaitCursor();
if(m_Ekpass==1)
{
//Check if the Tools are already installed
PwdMgr = ToolExistCheck(EKPWDMGR, "EKPassword Manager");
//Downloading
if(PwdMgr)
EKPwdMgrDLSuccess = Download(EKPWDMGR, "EKPassword Manager");
//Installing
if(PwdMgr && (EKPwdMgrDLSuccess == DLSUCCEED))
{
nStatus = InstallTools(EKPWDMGR, "EKPassword Manager");
if(nStatus == DLSUCCEED)
InstallPackages(EKPWDMGR, "EKPassword Manager");
}
this->EndDialog(0);
}

Why you use of this code
CFileOperation *fileOpr = new CFileOperation();
|
|

|

Hi,
have you tried to insert your own "stop"-points with AfxMessageBox () to see where it exactly crushes?
And, on the other hand...
this->EndDialog(0);
void EndDialog( int nResult );
Parameters
nResult: Contains the value to be returned from the dialog box to the caller of DoModal.
Why don't you use a simple "return 0;" ??

I got some crashes in the same moments.
In my case it was because I tried to free things in the destructor of the dialog and, as the window doesn't exists at that moment... I got assertions while trying to delete contents of members.
Maybe...
