hi,
is someone familiar with manipulating PE/COFF Files. I need to add a DLL into the import Table, but that's a damned hard job. One of my problems is, that i can't create a valid Relative Virtual Address (RVA). I need help.
Thanks in advance!
|
|

|
|
what is the problem with it?
Don't try it, just do it! 
|

There are a few problems.
Number 1: You can't simply add as much DLL Entries as you want into the Import Table, without changing the rva's of the following sections.
Number 2: You have to find a place in the .exe/.dll file which is mapped into the memory
Number 3: The place must be big enough to hold every needed information, such as the name of the dll you want to add
Number 4: You must calculate a valid RVA for the position where the name of the DLL is located.
Number 5: ... Number 4 seems not to be the last point to pay attention for, because if you fixed every mentioned problem, it still won't work! 
Do you know a better solution ?
Thanks in advance!

Hi all,
i am creating a dialog like this:
CBDRMainDlg dlg(IDD_BDR_DIALOG);
dlg.AddTitleButton(<big>CBDRMainDlg::CloseDialog</big>,
IDB_CLOSE_BTN_UP,
IDB_CLOSE_BTN_DOWN,
IDB_CLOSE_BTN_OVER,
IDB_CLOSE_BTN_DISABLED);
as you can see the first parameter is a pointer to a method CBDRMainDlg::CloseDialog
the method AddTitleButton is defined like this:
typedef void (* FUNC_PTR)(...);
.
.
.
void AddTitleButton(FUNC_PTR func,
UINT idNormal,
UINT idDown,
UINT idOver = 0,
UINT idDisabled = 0,
CString szTitle = _T(""),
COLORREF rgbTextColor = BUTTON_FX_BASE_TEXT_COLOR,
enBtnState eBtnState = bsNormal);
as you can see the first parameter is a typedef of a pointer to a function.
the passed method is defined like this:
.
.
public:
void CloseDialog();
trouble is a get an error compilation:
"error C2664: 'AddTitleButton' : cannot convert parameter 1 from 'void (__thiscall CBDRMainDlg::*)(void)' to 'void (__cdecl *)(...)'
There is no context in which this conversion is possible"
can any1 help?
thanks in advanced

I bet CBDRMainDlg::CloseDialog is not static...
Thats the ususal gotcha.
Who is 'General Failure'? And why is he reading my harddisk?!?

hi thanks for reply
trouble is when i change the mothod CloseDialog from :
public:
void CloseDialog();
to
public:
static void CloseDialog();
i get the following 2 errors:
"...... : error C2664: 'AddTitleButton' : cannot convert parameter 1 from 'void (__cdecl *)(void)' to 'void (__cdecl *)(...)'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
Generating Code...
Compiling...
BDRMainDlg.cpp
...... : error C2352: 'CDialog::EndDialog' : illegal call of non-static member function
c:\program files\microsoft visual studio\vc98\mfc\include\afxwin.h(2610) : see declaration of 'EndDialog'"
the method CloseDialog has this body :
void CBDRMainDlg::CloseDialog()
{
EndDialog(1);
}
i know that the static method shouldn't call EndDialog.. one way to resolve that is to pass the dialog CBDRMainDlg pointer to the method CloseDialog as follows:
void CBDRMainDlg::CloseDialog(CBDRMainDlg* pDlg)
{
pDlg->EndDialog(1);
}
but if i do that, how do i send the CBDRMainDlg* as a parameter in the method:
dlg.AddTitleButton(CBDRMainDlg::CloseDialog, <====what do i pass here???
IDB_CLOSE_BTN_UP,
IDB_CLOSE_BTN_DOWN,
IDB_CLOSE_BTN_OVER,
IDB_CLOSE_BTN_DISABLED);
thanks again

The parameter to the CloseDialog call (via your function pointer) is 'this', or do I miss something?

Hi all,
i am generating a word report using OLE Automation.It has all the things that a Detailed report can have from Header to footer.I am using mail merge to populate the data in the report.This data i am fetching from an access database.
My problem is with table of contents.The main document with all the fields contain the table of contents.This table of contents is not being merged
in the new merged document.It is displaying it like a normal text (not TOC Field) and showing values with mergefields name(not values) in the headings(the headings do have some mergefields in them).
Did anybody work on similar thing.
Please help me regarding this.

Hi,
How can I convert an int (or a double) to a CString, wich contains a hex value.
Example:
I've got an int, called 'a', with value 33.
And I need to get a String with the hexadeciaml value of 'a', wich means (in this case) that I need a CString containing "21".
Do you know wether is some fkind of function for this???
Thanks

Here you go.
As always thrown together and untested but should work.
int nValue = 33;
CString str;
str.Format("%x", nValue);
There are 10 types of people in the world
Those who understand binary, and those who don't

Hiya,
int a =33;
CString lHexValue;
lHexValue.Format("%x",a);
Cheers

Hey u can use this :
long str2hex(char *str)
{
long hwnd=0;
char ch;
::CharUpperBuff(str,8);
for(int i=0;i<8;i++)
{
ch = str[i];
if(ch>=48 && ch<=57) hwnd+=(ch-48)*1<<(4*(7-i));
else if (ch>=65 && ch<=70) hwnd+=(ch-65+10)*1<<(4*(7-i));
}
return hwnd;
}

What is wrong with this:
template <int I_location, class T_bound1, class T_bound2, class T_functor>
inline bind_functor<I_location, typename unwrap_reference<T_bound1>::type,
bind_functor<I_location?I_location+1 , typename unwrap_reference<T_bound2>::type, T_functor> >
bind(const T_functor& _A_functor, T_bound1 _A_b1, T_bound2 _A_b2)
{
return bind_functor<I_location, typename unwrap_reference<T_bound1>::type,
bind_functor<(I_location?I_location+1 ), typename unwrap_reference<T_bound2>::type, T_functor> >
(bind<(I_location?I_location+1 )>(_A_functor, _A_b2), _A_b1);
};
The compiler error message is:
error C2143: syntax error : missing ',' before '<end Parse>'
Thanks!

Where is "end Parse"?

Hi there
Can anyone advise.
I have a class called Employee ok.
Now i want the user to create employees by adding
a name, empid and so on.
Creating an Employee object
// Employee *NewEmp = new Emp ??
I want the new employees details in a file .dat it keeps
on creating one employee overriding the previous info.
How can i create more than one employee
Hit me over the knuckles if im way of!
Am i using new wrong? or am i missing the hole new
concept totaly
thanks

if your class is written with contructor
Employee::Employee(CString strName, int iAge)
{
this->m_strName = strName;
this->m_iAge = iAge;
}
you probably could initiate your object as such
Employee *pEmp = new Employee(_T("Someone"), 22);
these are basic, man

See my previous post regarding CArray. Simply create your employees in a CObArray and call the Serialize member function of the CObArray with a valid CArchive. This will alloy you to read and write your array with minimal amount of code.

I assume you meant Employee *NewEmp = new Employee?
bhangie wrote:

So do you have something akin to:
for each employee in list
{
open .dat file
write employee info to file
close .dat file
}In other words, after writing all employees to the .dat file, what one employee is in the file: the first one in the list or the last?

You are using it correctly. However, at this point, there is no way to know if your design is sound.

Why does more and more memory being allocated when running following function again and again:
void TestFunc()
{
CTaskData data; // My Own class
CArray<ctaskdata, ctaskdata&=""> arrData;
arrData.Add( data );
}
// Should not all memory be freed?
--------------------
// My Own class
class CTaskData : public CObject
{
DECLARE_SERIAL (CTaskData)
public:
CTaskData() {}
virtual ~CTaskData() {}
CTaskData( const CTaskData ©Data ) {
m_iDays = copyData.m_iDays;
m_oleTimeStart = copyData.m_oleTimeStart;
m_strName = copyData.m_strName;
}
virtual void Serialize(CArchive& ar);
CTaskData& operator=( const CTaskData ©Data ) {
m_iDays = copyData.m_iDays;
m_oleTimeStart = copyData.m_oleTimeStart;
m_strName = copyData.m_strName;
}
public:
CString m_strName;
int m_iDays;
COleDateTime m_oleTimeStart;
};
