Hi all.
I am trying to customize the cookie data in the http headers of my IE. That is to say I must add my own 'Cookie' header to standard IE http headers. But, each time when I use IWebBrowser2::Navigate2() function to add 'Cookie' header(such as 'Cookie: jsessionid=0DE9IIUD03D23'), the 'Cookie' header will be filtered by IE. It seems that the 'Cookie' header is maintained by IE itself and it is not changeable.
Is there any way to modify IE's 'Cookie' http header according to you need?
Any suggestion will be appreciated.Thanks very much.
Leo.

We have been developing a VC++ 6.0 application in Windows NT service Pack 6a OS, Which interfaces with Data collection
Hardwares(mounted in ISA/PCI slot of the computer) through their DLL's.
We have the following function call problem as follows:
Our application header files are defined as ollows:
***********************************Our application Header
file********************
#include "DLLHeader.h"// Dll definitions are included
Class OurClass
{
public:
void (*InitBoardfunction) (WORD Addr, WORD IRQNo);
WORDBOOL (*BoardIsOkfunction) (void);
: :
: : :
: : :
: : :
void (*Setfunction) (WORD set);
BOOL GetDLLPointers(void* ptr);
BOOL InitDAQ(void);
};
***********************************Our application Header
file********************
Our application Implementation files are defined as follows:
***********************************Our application Implementation
file********************
// This function gets function pointers of the DLL.
BOOL OurClass::GetDLLPointers(void* ptr)
{
HINSTANCE handle;
CString ErrMsg;
CString ErrTitle;
COurappDoc* pDoc;
pDoc = (COurapp*)ptr;
SetCurrentDirectory(pDoc-SetupEnviron.OurappInstalledDir); // Sets
the current Directory as the application Installed Dir.
handle = AfxLoadLibrary(_T"Board.dll"));
InitBoardfunction = (void(__stdcall*)(WORD,WORD)) ::GetProcAddress(handle,"InitBoardfunction");
ASSERT(InitBoardfunction != NULL);
BoardIsOkfunction = (WORDBOOL(__stdcall*)(void))
::GetProcAddress(handle,"BoardIsOkfunction");
ASSERT(BoardIsOkfunction != NULL);
: : :
: : :
: : :
: : :
Setfunction = (void(__stdcall*)(WORD)) ::GetProcAddress(handle,"Setfunction");
ASSERT(Setfunction != NULL);
return TRUE;
}
// DLL functions are getting called in this function.
BOOL OurClass::InitDAQ(void)
{
CString ErrMsg;
CString ErrTitle;
InitBoardfunction(0x300,5); // First DLL function call
: : :
: : :
: : :
: : :
Setfunction(1); // application crashes here.
}
About 8000 lines of "First-chance exception in Simple.exe (KERNEL32.DLL):
0x0EEFFACE: (no name)." messages are getting printed in Debug window,
after executing the first DLL function call (InitBoardfunction(0x300,5)) in our
application, While I am in the debug mode. After calling couple of other
DLL functions, Setfunction(1) is getting called in our application.
After executing the Setfunction(1) function call in our application,
my application crashes with the following message in the Debug mode.
"File: i386\chkesp.c
The value of ESP was not saved across a function call .This is usually a
result of calling a function declared with one calling convention with a
function pointer declared with a different calling convention."
I opened up Registers window, Disassembly window while debugging the sample code. The assembly code is as attached for
the "Setfunction(1)" function call
004036D9 8B F4 mov esi,esp
004036DB 6A 01 push 1
004036DD 8B 45 FC mov eax,dword ptr [ebp-4]
004036E0 FF 50 1C call dword ptr [eax+1Ch] //ESI register values are getting changed after this
function call.
004036E3 3B F4 cmp esi,esp
004036E5 E8 86 BF 01 00 call __chkesp (0041f670)
ESI register value is getting changed from 0012F82C to 0012F94C, after the function is getting called.
Can anyone help me by answering the following:
1. What are all the possible reasons for changes in ESI register value. Is there a problem with DLL. If it is, What
might be the problem in DLL & Please suggest what to Do for the DLL supplier to solve this problem.
2. The same typical code is working without any problem in Borland C++ Compiler. Is there any settings in VC++ to be done
to avoid this Crash.
3. How to avoid "First-chance exception in Simple.exe (KERNEL32.DLL): 0x0EEFFACE: (no name)." messages(about 8000+) in
the debug window. This message is getting printed when you call the first DLL function (InitBoardfunction(0x300,5); ) in
our application.
Also Please note that Our application is an existing application & it was working fine without any problem with an Old
DLL supplied by the supplier. Our Hardware supplier did some revisions in the DLL to make it work for both ISA as well as
PCI slot Data Acq Cards. The subject problem started there.
Please note that our application is being compiled with /Gz option as the DLL functions are written in Delphi & exported
by __stdcall function call type
Could you please help me to solve this problem in our application.

Shouldn't you have __stdcall here as well, so:
void (* __stdcall InitBoardfunction) (WORD Addr, WORD IRQNo);
?

Thanks for your reply.
I already tried by putting the function declared as you said.
void (* __stdcall InitBoardfunction) (WORD Addr, WORD IRQNo);
But Still the error exists.

Hm. The code you showed would give this error. It's also typical when using DLL:s that works with Borland (due to different default calling conventions), and moreover, constistent with the error message.
Have you checked, double-checked and then triple-checked that you have really tested a version with __stdcall in the definition as well? Made a Rebuild All, made sure that the original DLL really uses the new code etc.
This might sound impertinent, but I sat the day before yesterday and debugged the same bad DLL for hours, until I realized that all the changes I made had no effect, the test-app didn't use the newly built ones 
|
|
|
|
|
Yes, I checked so many times that the function definition is with __stdcall type only.
|
|
|
|
|
Could you post the updated code here instead?

Where can I find the API for MS Outlook 2000? Searched MSDN but know where to read…
I’m heading into automation programming in VC++ and have created wrapper classes (for msoutl9.olb)

The documentation for programming Outlook via C++ is very poor. Try searching MSDN for "Microsoft Office 2000 Language Reference" which gives details of Outlook object model (in VB, but it's better than nothing).
Also try looking in the Knowledge Base for article 196776.

I recently had to do the same thing (retrieving message objects from the user's inbox), and I used two tools: one was doing a google search on words related to what I was trying to do. the other was using the outlook helpfile that should be on your machine 'VBAOUTL9.chm'; that helped me more than anything. If there's anything specific, post it and i'll see if there's a way I can help
If it's broken, I probably did it

I've manage to created wrapperclasses and starting using automation. (I'm not really sure what it means but anyway).
I manage to run this code:
...<br />
if(!app.CreateDispatch("Outlook.Application"))<br />
{<br />
AfxMessageBox("Couldn't start Outlook.");<br />
}<br />
else <br />
{<br />
app.Quit();
}<br />
and Outlook closes if I have it open. But I don't know how to for e.g. start Ouutlook, create a mailmessage, fill To, Subject and Body and then send it using “this automation stuff”.
Thanks

THANKS!! Your code made me think a bit and found out these simple lines to send a message:
_MailItem mail = app.CreateItem( 0 );
mail.SetTo( "blubb@syd.kth.se" );<br />
mail.SetSubject( "Mail from VC++ automation" );<br />
mail.SetBody( "The BODY" );<br />
mail.Send();<br />
but still I'd like to find any MS Outlook C++ Reference somewhere. I googeld but no success.

hi,
i got Doc/View app with database queries.
in which function in the Doc should i do the query?

Qué?
You can place your queries anywhere you like. Whether the appropriate place to put yor DB queries is in the Document, View or even the Application class is up to your program's design.
Maybe you should read up a little bit more on the
Doc/View[^] architecture to help answer your question.

PROBLEM
Unable to understand the variation in size of object
All the code is tested under Borland C++ ver 3.1
In borland V3.1 the int takes two bytes
Lets look at the following code
Class base<br />
{<br />
public:<br />
int b;<br />
base()<br />
{}<br />
virtual void f() {}<br />
virtual void g() {}<br />
};<br />
Class derive : virtual public base<br />
{<br />
public:<br />
int d;<br />
derive()<br />
{}<br />
virtual void f() {}<br />
virtual void g() {}<br />
};
………………
derive d;
cout<<sizeof(d); <b="">gives 12 why?
/*
But if I don’t give constructors in derive then the size of derive class object is 10, because there will be no 2 bytes extra in object layout as shown below. Please help me out about finding the myth of these extra two bytes.
*/
Object-Layout V-TABLE

Can I ask why you need to know? A compiler is at liberty to decide how to layout a class - the C++ standard doesnt define this. I recall finding a description of different methods on the net, so you should be able to find the details from google. I would imagine the extra byte is for some internal use by the Borland compiler, or maybe even just for padding. Either way, you shouldnt base code upon the size of an object, as compilers will give different sizes.

2 extra bytes meanse shortage of ram
Even if there is know reason one should know the myth of this mystry
------------------------------------------------------------You miss 100% of shots that u dont take.

|

Saving 2 bytes! You must be kidding - for a 1 000 instances of the class, this means (less than) a meagre 2 kbs of wasted space. This is not uncommon - "wasting" memory, that is - structs will be padded, for example, for reasons of performance.
You should just leave this to the compiler-writers, madness lies in this direction 
|

I think it's related to your use of virtual inheritance. What's your reason for making the inheritance relationship 'virtual'?
Paul

|

|

It may have everything to do with keeping VTables on 4-byte boundaries.
Since VTables will resolve into pointers to functions in derived classes, they want to keep them aligned so the performance on the CPU is better.
As an experiment, you can try changing
public:
int b;
base()
into
public:
byte b;
base()
And you will still probably get 12.
Then try
public:
int b;
int c;
base()
And you might still get 12.
I think it has do do with optimizing pointers to tables of function pointers, myself.

Hello Guys,
How ru doing, I need some help in FTP, first i will clearly explain u the situation.....
i have one one FTP user login, i have logged into the FTP server with that login, now by code i need to know how much space like .... The total space allocated for the user, the space occupied by the user, and the remaining space.
currently i have one solution...but its not working fine...i.e i can execute a FTP command through code like "ls", doing this will return a string to me containing the result(text string) for the executed command. the problem here is this is not working all the time....if the data commection is lost it just hangs offff and many other problems are there.
guys plz help me out of this problem....waiting for the solution

in UNI*/perl
<br />
$dir = "/myserver/mydir";<br />
$aa=qx(du -s -k -m $dir);<br />
print "<BR>size of website in MB $aa<BR>";
in FTP I think your only solution is to manually recurse through all the subdirectories geting the size of each file, if you are using the MFC CFtpFileFind is one solution

Ted...thanks for ur reply man...
Actually the Server which iam going to connect is Windows wunning Windows Media Server
