Hello friends,
I have created a folder, which is a shared folder on network.
Now as we know that there are sharing rights like Read, read/write,....etc.
I want to give Read only access to the folder. i hve tried with the ACCESS_READ Flag with the Netshare function but it Fails i mean the folder is still having Read/Write Access !!!!!!!!!!
Can anybody help me out ???????
Thanx

Hi,
I'm looking for some kind of "VC6 project templates" - i.e. generate the same settings based on an existing .dsp, with a new name etc., but keeping compiler/linker settings, project configurations, etc.
I looked into custom appwizard, but it only generates default configurations.
[edit]I figure a tool where I can pre-configure a search-and-replace, *including* S&R in file names, could dothe job...[/edit]

I never seemed to be able to get it to work when it generates from another project properly either.
Alternatively, create a default project *similar* to what you want (MFC / DLL / Console), then add the source code, you can then use the text from the 'project->settings->link->project options' and 'project->settings->compile->project options' edit boxes to rebuild your compiler options.
I've found that custom appwizards can take quite a while to get exactly right - so if you can use a find and replace for a one off, do that instead.
Some Gotcha's for Custom Appwizards
in 'void CYourProjectAw::InitCustomAppWiz()' make sure that the dictionary sets the correct type of project. For example,
m_Dictionary[_T("PROJTYPE_CON")] = _T("1");
in 'void CYourProjectAw::CustomizeProject(IBuildProject* pProject)' you can set all the compiler options. MSDN / VC6 samples are the best source of info for this. It can be really painful to do this right, because it has to be done for the debug and release builds.

Hi!
I try to wrap a c++ lib behind a COM dll to make it easy to use by VB or c#.
But i have some troubles. Look the demo:
There is two classes in COM DLL, one called Apple and another called Banana.
In Apple i try to hide a struct. It is not on the interface to the client. But the other class in the COM know it is there, and can access it.
struct Image
{
int num;
};
// CApple
class ATL_NO_VTABLE CApple :
public CComObjectRootEx,
public CComCoClass,
public IDispatchImpl
{
public:
Image img;
CApple()
{
}
The class banana has two methods, GetApple create an Apple object and initialize its value, QueryApple try to query the value in the Apple.
interface IBanana : IDispatch{
[id(1), helpstring("GetApple")] HRESULT GetApple([out,retval] IApple** apple);
[id(2), helpstring("QueryApple")] HRESULT QueryApple([in] IApple* apple, [out,retval] int * ret);
};
And in banana.cpp i try
STDMETHODIMP CBanana::GetApple(IApple** apple)
{
CApple* p = new CComObject();
p->img.num = 100;
*apple = p;
return S_OK;
}
STDMETHODIMP CBanana::QueryApple(IApple* apple, int* ret)
{
CApple* p = dynamic_cast(apple);
*ret = p->img.num;
return S_OK;
}
But when i use this dll in c#, it always get a System.ExecutionEngineException.
the script is
FruitLib.Banana banana = new FruitLib.BananaClass();
FruitLib.Apple apple = banana.GetApple();
int n = banana.QueryApple(apple);
What's wrong in my code? Any idea?
Thanks!

Firstly, when posting code to CodeProject, it's useful to use the <pre> format tag. You should also translate < to < and > to >. Alternatively select the 'Display this message as-is (no HTML) checkbox). Otherwise CP interprets template parameters and system includes as unknown HTML tags and removes them.
Now for the problem:
System.ExecutionEngineException, according to the documentation, is only thrown when an internal problem occurs in the runtime itself.
The problem seems to be occurring when the Interop layer tries to call QueryApple. It never actually gets into the C++ module.
I'll have to confess, I'm not an expert on Interop. I think you need actual support from MS on this one.

Hi,
is there any way through which i can check into the Access database wheteher the table is created or not?
|
|
|
|
|
you can check the MSysObjects table.
or search for something like:
m_pConnection->OpenSchema((ADOCG::SchemaEnum)eSchema)
it returns a recordset with some infos about the DB

Hi,
thanks for reply.
I am new to databases,so i am not able to implement your suggestion into code.
I am sending my present code .It will be of great help,if you show me direction from here.
CString sDriver;
sDriver = _T("MICROSOFT ACCESS DRIVER (*.mdb)");
CString sDsn;
sDsn.Format(_T("ODBC;DRIVER={%s};DSN='';DBQ=%s"),sDriver,sInstallDir + _T("\\v010\\Program\\MDD.mdb"));
if(!m_pDatabase->IsOpen())
{
m_pDatabase->Open(NULL,FALSE,FALSE,sDsn);
}
.............................................................
//HERE I NEED THE CODE TO CHECK WHETHER THE DATABASE HAS ANY TABLES ,IF YES ,I NEED TO DELETE THOSE TABLES.
..............................................................
I DON'T KNOW HOW TO GET CONNECTION OBJECT HERE BECAUSE I DON'T FIND ANYTHING LIKE CONNECTION OBJECT WHILE USING ODBC,CDATABASE AND CRECORDSET CLASS.
....................................................................
ANY HELP WILL BE GREATLY APPRICIATED.
..........................................
THANKS AND REGARDS.

How can i find out that where this error is originating. When i double click these lines in debug window, nothing happens.

Try out Numega Boundschecker. Fully automated.
Good tools.
Or manually in your codes. Place in CMemoryState to get the allocated bytes for in the codes to see the before and afterso that you know which part is leaking. A bit tedious but at least it is free. (Come with MFC)

I load one graphic file (jpeg) into picture control (picture control 1) using CImage with code image.Load(); and then by using .setbitmap((HBITMAP)image) to bind it into picture control.
I need to cut a portion of this image, I am using this code:
hdcDest = ::GetDC( CpThis->m_CpDest->GetSafeHwnd() );
hdcSrc = ::GetDC( CpThis->m_CpSource->GetSafeHwnd() );
::SelectObject( hdcSrc, CpThis->m_BackSurface.hBmp );
::StretchBlt(hdcDest,0,0,300,400,hdcSrc,pointlx,pointly,cutwidth,cutheight,SRCCOPY);
::DeleteDC( hdcSrc );
::ReleaseDC( CpThis->m_CpDest->GetSafeHwnd(), hdcDest );
and it work, the result will be display into picture control 2.
The problem here are it is not bind it into picture control, It just use picture control as an frame to display it and how to save it into a file (result.jpg).
Any body have the idea to solve this problem, I really appreciate it.
Thanks you.

I'm not 100% sure on this, but I think you need to use __try/__except to catch hardware faults or GPFs. try/catch are only for C++ exceptions.

Typically it might be because of the use of a NULL pointer.
Why don't you look it to the condition that creates this exception?
|
|
|
|
|
Exactly, do ASSERT in the codes.

actually, i don't know exactly the problem.
it occur sometimes. it is a serial commu. application. i think it related to overlapped IO problem.
