Why?
Do you think you're getting some benefit from having a second thread
used that way?
That sure is a complicated way to do single threaded programming.

Hi All,
I wanted to use NET API in my MFC application, since this was new to me I started out with a simple application listed below
#include "stdafx.h"
#include "myapp.h"
#using <mscorlib.dll>
#using <system.dll>
using namespace System;
// The one and only application object
CWinApp theApp;
using namespace std;
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;
// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
_tprintf(_T("Fatal Error: MFC initialization failed\n"));
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
Console::WriteLine("This is a MFC app using NET API");
}
return nRetCode;
}
Till few days back I was able to successfully compile and run this simple application using VC++ 2005 with SP1, however now when I am trying to compile the application I am getting the following error
1>.\myapp.cpp(45) : error C3666: 'System::Security::IEvidenceFactory::IEvidenceFactory' : override specifier 'new' not allowed on a constructor
1> This diagnostic occurred while importing type 'System::Security::IEvidenceFactory ' from assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

The MSDN documentation is not very helpful on the error message and also the fact that I am new to NET arena so I really do not understand what went wrong.
In the last few days I have installed DotNET framework 2.0 SP1 on my machine and many other applications required by my project so it is difficult for me to go back to pre 2.0 SP1 configuration.
Does someone no what is this error? And how do I get rid of this.
Thanks and Regards

You cannot use the .NET framework from a native application (MFC, C, C++, whatever).
If you want to use applications that exploit the features of .NET framework, then you will need to write code in one of those managed languages (C#, VB.NET, CLI/C++)

You can make a dll and use of it on the c++ or vice versa.

what do you think the docs[^] are for ???

Use CreateProcess if you want more control over process being spawned
Somethings seem HARD to do, until we know how to do them.

What does RPC or MIDL has to do here?  You want to learn RPC or just run an executable?
If you need to run an executable, you just need ShellExecute or CreateProcess as someone already said.

Reason is here[^]. Check whether you've defined your _STORAGE_BUS_TYPE more than once.

thax's problem solve.Just i comment it..
But i have found some more error..
[code]
error C2061: syntax error : identifier 'PSTORAGE_DEVICE_DESCRIPTOR'
error C2511: 'bool CMy4Dlg::GetDisksProperty(HANDLE,PSTORAGE_DEVICE_DESCRIPTOR)' : overloaded member function not found in 'CMy4Dlg'
error C2061: syntax error : identifier 'PSTORAGE_DEVICE_DESCRIPTOR'
[/code]
so plz help me
|
|
|
|

From MSDN[^], i found STORAGE_DEVICE_DESCRIPTOR is declared in header file - Ntddstor.h. So check whether you've included it or not.
Regards,
Jijo.

Check whether the signature of CMy4Dlg::GetDisksProperty() is exactly same in header and in cpp file?

Jijo.

Hello everyone,
I am inserting vb activex control in VC program.In VB ocx program i am passing variables of type recordset from database.when i am inserting this ocx into my VC program those recordset datatypes are converting as LPDISPATCH* type. and my variables of type CRecordset. it is giving error like this:
C:\Program Files\Microsoft Visual Studio\My Projects\RecordSetPgm\RecordSetPgmDlg.cpp(255) : error C2664: 'Processattendacne' : cannot convert parameter 1 from 'class CRecordset' to 'struct IDispatch ** '
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
VB ocx Code is like this:
void C_UserControl1::Processattendacne(LPDISPATCH* rs, LPDISPATCH* rs1, BOOL* blnprocess)
{
static BYTE parms[] =
VTS_PDISPATCH VTS_PDISPATCH VTS_PBOOL;
InvokeHelper(0x60030000, DISPATCH_METHOD, VT_EMPTY, NULL, parms,
rs, rs1, blnprocess);
}
And VC++ Code is like this:
database.Open(NULL,false,false,sDsn); // Open Clients.MDB
CRecordset recset( &database );
SqlString="SELECT field1 FROM sample";
recset.Open(CRecordset::dynamic,SqlString,CRecordset::readOnly);
CRecordset recset1(&database);
Client= "SELECT field2 FROM sample";
recset1.Open(CRecordset::dynamic,Client,CRecordset::readOnly);
m_UserControl.Processattendacne(recset,recset1,bstr);
database.Close();
please tell me what type of parameters i have to take and how should i declare those please tell me...please Help me out..i am trying this but i am not getting...please give me some suggestions..
Thanks in Advance,
Savitri

CRecordset is an MFC class which is not IDispatch compatible. VB ActiveX method that you are using, requires an IDispatch interface as parameter. If you use ActiveX Data Object (ADO) instead of CRecordset class then you will be able to pass the object to your VB ActiveX methods. I have included the link to samples in my previous post. These will help you get started.
I hope this helps.
