well simplly you can move all the supporting exes to another folder, and then run the main application, Then it will start complaining about the exes missing and you then come to know the order of the supporting exes called.

Hi,
I don't know what are the exes called by the application. That's the problem.

U mean to say that U don't have the code of the application. Then U are trying to do reverse Engineering. If yes? you are going to loose Ur hairs soon.

This is an uninstall program.

after delete all other files, the uninstall app needs to delete itself.

but i failed to do that.

which function is available for deleting a program itself?

Most of us (now days) use some body elses program to create the install/uninstall and do not worry about the details. But basicaly a small program that is loaded in memory can delete its' own files and directories and when it exits it no longer exists.

DeleteFile() might do the job. I can not remmeber or find the standard C method.

hello david
this is my code for saving mail in outbox
this is automation code
its notworking but when i make call to send it send mail directly
but i only need to place in outbox folder

_Application pApp;
COleException e;

if(!pApp.CreateDispatch("Outlook.Application", &e)) {
CString str;
str.Format("CreateDispatch() failed w/error 0x%08lx", e.m_sc);
AfxMessageBox(str, MB_SETFOREGROUND);
return;
}

COleVariant covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);
_NameSpace pNameSpace;
MAPIFolder pOutbox;
_Items pOutboxItems;
Attachments pAttachments;
Recipients pRecipients;
Recipient pRecipient;

// Create NameSpace pointer.
pNameSpace = pApp.GetNamespace("MAPI");

pNameSpace.Logon(covOptional, covOptional, covOptional, covOptional);

// Prepare a new mail message
_MailItem pNewMail(pApp.CreateItem(0));

pOutbox = pNameSpace.GetDefaultFolder(4);//getoutbox folder
pOutboxItems = pOutbox.GetItems();

pNewMail=pOutboxItems.Add(covOptional);//put the message in out boxx

pNewMail.SetTo("global_com2000@yahoo.com");
pNewMail.SetSubject("Test...");
pNewMail.SetBody("Hi Mapi\n\n");

why to initialize like this ?

the initialization below ,why to written like this?
CStudent(const char* szName, int nGrade) : m_strName(szName)
{
m_nGrade = nGrade;//m_strName,m_nGrade are both the membe of the class C
}
but i written like this:
CStudent(const char* szName, int nGrade)
{
m_strName=*szName;
m_nGrade = nGrade;
}
the program still run normally,why the original don't write as the same as mine,i want to when to write like the first style rather than the second style?

be careful on such code... you are copying a string, but in fact, just copying the address of that string. this can be so dangerous !
for example, if that string come from a variable (dynamically allowed), you execute such code (CStudent()), and then you destroy the first, you m_strName will point then a free area.

What you have to do is to copy the entiere string while constructing your object :

<font style="color:blue;">#include</font> <string.h>    <font style="color:green;">// strcpy()</font>
 
CStudent::CStudent(<font style="color:blue;">const char</font>* szName, <font style="color:blue;">int</font> nGrade) { 
     strcpy(m_strName, szName);     <font style="color:green;">// you can do it by yourself if you prefer with a for loop</font>
     m_nGrade = nGrade;
}

what happens when you do CStudent(const char* szName, int nGrade) : m_strName(szName), it is that call a constructor that allocates a new object for fou, and then, copies m_strName with it. In this case, are you sure it really works ?

VERY WRONG m_strName = szName is not coping the address of the string, unless m_szName is a pointer. You can not copy use strcpy, unless the m_strName object already contains a string that is as long or longer than the string you are coping to it. He has various choices:

CStudent::CStudent(const char* szName, int nGrade) : m_strName(szName), m_nGrade(nGrade)
{}

CStudent::CStudent(const char* szName, int nGrade) : m_strName(szName)
{ m_nGrade = nGrade; }

CStudent::CStudent(const char* szName, int nGrade) : m_nGrade(nGrade)
{ strName = strName }

CStudent::CStudent(const char* szName, int nGrade)
{  m_strName = szName; m_nGrade = nGrade; }

But strcpy is not one of them. Of course your answer and mine have nothing to do with the actual question.

Sorry, but you scared me with your answer.

sorry but, szName and m_strName are char*, so they are pointers ! pointers contain addresses...

and when you use the operator=() on such type, it won't duplicate the string, but only what is inside the variables, here, the address of the C-string !

He did not give the definition of m_strName. Therefore we can conclude that it is a char*. If m_strName was a char* then you could not use m_strName(szName) in the initilization list, which is what the question was about. If he can use it in the initilization list then m_strName is not a char*.

i have a try in this way ,run well,the code is below:

class CStudent : public CObject
{
DECLARE_DYNAMIC(CStudent)
public:
CString m_strName;
int m_nGrade;

CStudent()
{
m_nGrade = 0;
}

CStudent(const char* szName, int nGrade) : m_strName(szName),m_nGrade(nGrade)
{ //strcpy(m_strName, *szName); //if this way ,it doesn't run well
//m_nGrade = nGrade;
}

CStudent(const CStudent& s) : m_strName(s.m_strName),m_nGrade(s.m_nGrade)
{
// copy constructor
//m_nGrade = s.m_nGrade;
}
i wonder m_strName,m_nGrade are only the member variable of the class CStudent,why in constructor to write : CStudent(const char* szName, int nGrade) : m_strName(szName),m_nGrade(nGrade)
?
whether this case still satisfy the other cases.

m_strName is a CString. You cannot 'strcpy' to a CString, this is a complete blind alley.

CStudent(const char* szName, int nGrade) : m_strName(szName)
{
}

calls the CString constructor that takes a const char *.

CStudent(const char* szName, int nGrade)
{
   m_strName = szName ;
}

calls the default CString constructor to initialise an empty string, and then calls the operator= function to set the CString to the string pointed to by szName.

In other words the former is more efficient and explicit, the string gets directly initialised with its contents. Additionally you could declare m_strName as 'const', assuming it isn't allowed to change during the lifetime of the class instance.
