i have got 85 users i have to store their login details in a file in the encrypted format each time the user selects the save button after providing the details i will be storing into the file in the following way
fpa=fopen(strFilename,"a");
file.open (strFilename);
str="URL="+data1+st+"USERNAME="+user+str1+"PASSWORD="+pwd;
pszDataIn4= new char[str.GetLength ()+1];
strcpy(pszDataIn4, str);
memset(szDataIn4, 0, 96);
memset(szDataOut4, 0, 96);
strcpy(szDataIn4, pszDataIn4);
iBlowFish.Encrypt((unsigned char*)szDataIn4,(unsigned char*)szDataOut4, 96, CBlowFish::ECB);
fputs(szDataOut4,fpa);
fputs("\n",fpa);
this will be done when user cliks on save button each time ;
now i need to decrypt it and show the corresponding details when the user cliks on the particular the next time
i have tried it by reading the whole file and then decryypt it but its not reading the encrypted file

parichaybp,
I think this code dont work because you declare
CCreateDlg *m_dCreateDlg;
[I think you get a error like this the variable m_dCreateDlg is begin used without.....]
and I again repeat question
whats type CCreateDlg ? (example in header file -> Is class CCreateDlg : public CDialog?or....)
|
|
|
|
|
CreateDlg is Dialog window its same as UpdateDlg both the dialog window i have added using add resources...

well,
-------------In Main File CssDlg-------------------------
#include "test2.h"
....
private:
class CTest2;
//Then declare a pointer:
CTest2 *m_dlg;
---------------------------
void CssDlg::OnBnClickedButton3()
{
m_dlg.DoModal();
}
d:\Projects\ss\ssDlg.cpp(418): error C2228: left of '.DoModal' must have class/struct/union type
then I use
void CssDlg::OnBnClickedButton3()
{
m_dlg->DoModal();
}
d:\Projects\ss\ssDlg.cpp(418): error C2027: use of undefined type 'CssDlg::CTest2'
d:\Projects\ss\ssDlg.cpp(418): error C2227: left of '->DoModal' must point to class/struct/union
I find your problem delete
private:
class CTest2;//Then declare a pointer:
CTest2 *m_dlg;
--------------------------------------
and you should CTest2 m_dlg;
Now It's work

hi whitesky,
Problem is there are 2 Dialog window, in the UpdateDlg dialog when i click on new button it should open create dialog window...
please can u tell me what should be done and how the declaration shd be done ...
|
|
|
|
|
|
you are declaring the pointer in the CreateDlg file for the dialog
That should be done in UpdateDlg.h
that's all

Hi,
I have a small problem when using enums with VC++. Although, I use enums a lot with C#, I am having problems using them in VC++. Let me explain.
I have the declaration in the header file:
class CContext <br />
{<br />
private:<br />
<br />
public: <br />
enum ContextType<br />
{<br />
Context1 = 0,<br />
Context2<br />
} ;<br />
<br />
CContextMenu() ;<br />
virtual ~CContextMenu() ;<br />
bool AddContextItems( ContextType cT ) ;<br />
};
Then I have the implementation in the cpp file:
bool AddContextItems( ContextType cT )<br />
{<br />
return true ;<br />
}
But on compilation, I get the error, ContextType undeclared identifier.
Also, when I click on the function AddContextItems in the Workspace explorer window, it says, Cannot find defination(Implementation) of this file. Can you tell me why this happens?
Thanks,
---

Oh.. Its there... just forgot to add it...
My mistake...

{
//Do something
return true ;
}

Although it compiling fine now, I still get the cannot find declaration(implementation) of this file error.
Also, when I try to use the function from another class, I get the error,
error LNK2001: unresolved external symbol "public: bool __thiscall CContext::AddContextItems(enum CContext::ContextType)" (?AddContextItems@CContext@@QAE_NW4ContextType@1@@Z)
Can anyone help me decrypt this mumbo jumbo.... ?
I just can't figure out, what the error means?
