sorry ! and thank's for the advice
I'll try to explain more:
when I insert the control activeX in my CFormView I create for it a member
variable with the wizard of "VC++ .net" as a control in the category.
so it's like this :
CPrincipale::CPrincipale()
: CFormView(CPrincipale::IDD)
, m_DTC()
{
}
then I do what I said before
i put in the class port.h this line:
CMyinterfacectrl1 *pDTC; //pointer to the class which was created when I insert the control.
and I use it like this in port.cpp
pDTC->setWorkIndex(...);
pDTC->ComPortOpen(....);
in my CFormView CPrincipale.cpp
I call my CDialog like this:
void CPrincipale::onPort()
{
Cport p;
p.pDTC=&m_DTC;
p.DoModal();
}
I hope that is clear enough
please help me !

But, why are you doing that ? Why have a pointer to your activeX control in a class that has nothing to do with it ? (and your explanation is still not very clear...)
|
|
|
|
|
because if I want to add a control ActiveX I must select the FormView
right click > insert Control ActiveX
then select the control add variable > category control
so it generate two files here you are some code of itdcinterfaceCtrl.h
class CItdcinterfacectrl1 : public CWnd
{
protected:
DECLARE_DYNCREATE(CItdcinterfacectrl1)
public:
CLSID const& GetClsid()
{
static CLSID const clsid
= { 0xFB05973A, 0x3C1E, 0x46DC, { 0x95, 0x93, 0xDC, 0xEE, 0xC4, 0x29, 0xDC, 0x88 } };
return clsid;
}
virtual BOOL Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle,
const RECT& rect, CWnd* pParentWnd, UINT nID,
CCreateContext* pContext = NULL)
{
return CreateControl(GetClsid(), lpszWindowName, dwStyle, rect, pParentWnd, nID);
}
BOOL Create(LPCTSTR lpszWindowName, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd,
UINT nID, CFile* pPersist = NULL, BOOL bStorage = FALSE,
BSTR bstrLicKey = NULL)
{
return CreateControl(GetClsid(), lpszWindowName, dwStyle, rect, pParentWnd, nID,
pPersist, bStorage, bstrLicKey);
}
// Attributs
public:
// Opérations
public:
// _DITDCInterface
// Functions
//
void DoorTimeSchedule(LPCTSTR DoorTimeSchedule1, LPCTSTR DoorTimeSchedule2, LPCTSTR DoorTimeSchedule3, LPCTSTR DoorTimeSchedule4)
{
static BYTE parms[] = VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR ;
InvokeHelper(0xb, DISPATCH_METHOD, VT_EMPTY, NULL, parms, DoorTimeSchedule1, DoorTimeSchedule2, DoorTimeSchedule3, DoorTimeSchedule4);
}
void AccessDoor(LPCTSTR DoorIndex1, LPCTSTR DoorIndex2, LPCTSTR DoorIndex3, LPCTSTR DoorIndex4)
{
static BYTE parms[] = VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR ;
InvokeHelper(0xc, DISPATCH_METHOD, VT_EMPTY, NULL, parms, DoorIndex1, DoorIndex2, DoorIndex3, DoorIndex4);
}
but if I create a class to this control and not a member variable I don't obtain attributs and function chown below!

Sorry, but I still don't understand... What do you mean by creating a class to this control ?? Simply declaring an instance of your class outside your view class ? But, why do you want to do that, that's the real problem ! An activeX is a control (it inherits from CWnd), so it will be displayed on your view, dialog, ... So, it is logical that it is a member variable of your view or dialog. Why do you want it to be outside of your class ?

Hi Radhika,
You can use string manipulations to remove the prefix of drive letter. There are so many helpful functions in CString class.

I add sth based on your code follow:
CString drv = ((CIFlappApp *)AfxGetApp())->m_strAppDrive;
drv+="\:";
drv+="\\";
CString str = drv + "MyFavourites";
CString str1 = str;
CreateDirectory(str,NULL);
str+="\\";
CString sub = str+"Online Bookmarks";
CreateDirectory(sub,NULL);
sub= str+"Music";
CreateDirectory(sub,NULL);
sub= str+"Pictures";
CreateDirectory(sub,NULL);
sub= str+"Documents";
CreateDirectory(sub,NULL);
str1.TrimLeft(drv);
m_bookmark.PopulateTree(str1);

Hi all,
I was wondering if someone could help me with the following problem that is occuring.
The thing is that every now and again a computer of mine, gives a message that the computer has run out of resources. So the thing is, is there any way I can handle such an event in VC++. When I try to connect to that PC throught PC Anywhere, I can't because of this message.
Can anyone help???
Thank you in advance

Hi Programm3r,
You could use task manager to identify which process is abusing system resources.
And then try running Perfmon on your test pc and add various counters (for the failing process) to see why its running out of resources.
Add:
Virtual Memory
Private Bytes
Handles

In MFC how to achieve the functionality of selecting the multiple files . That is pressing control button multiple files can be selected.

Do you need to CFileDialog class
|
|
|
|
|
You will need to use the CFileDialog class for that, as whitesky already said. To be able to select multiple files, the m_ofn.Flags should have the OFN_ALLOWMULTISELECT flag set.

use _T("") instead of L

After using _T("") this error :

why not you simple use
CString tszSQL=T("INSERT INTO TQuote (m_ID,m_DateTimeStamp,m_MarketNo,m_MarketName,m_Bid,m_Ask,m_MarketState) VALUES (Sessionid,Timestamp,a,Market,Bid,Ask,d)");
as CString overload Const STring operator
