If you have code for creating a cookie, why can't you access it?

Thanx a lot DavidCrow,
in that post , i do not understand how to create m_piRequest object
before making a call "hr = m_piRequest->get_Cookies(&pDict);"
i am not that familier with COM.
I googled it : m_piRequest is The IRequest interface pointer ( if am not wrong)
please let me know how to create m_piRequest object before start using it,
do i need to do cocreate instance?
please help me in this.
basically.. i am hosting CWebBrowser2 derived class object on a dialog.
and using Navigate funtion to navigate to any URL of a web application.

My class which cooperates with MS Acces base looks like below:
In doted place I removed code as a not relevant for case:
Problem is that field mTekst in Acces is set as Memo type. And I wish
to place long report texts in.
My class can't transfer longer text then 255 chars otherwise it shows
an error. Temporarily I deal with it by cutting part of chars.
(Look in function LeftF()) . But a program is not functionally then.

What error? I believe that is a limitation of a Text field in Access. Consider a Memo field instead.

Field in Access is set as Memo.
When is put more then 255 characters an error appears:
"Error: field address (column 2) has changed!"
and shows assertion info
Debug Assertion Failed
.....
File:dbrfx.cpp
Line 287
It happens while program executes Update() function.

The actual assertion is line 287 of dbrfx.cpp in the CFieldExchange::Default() method. You might want to step into that code to see why the field's address is changing.

It seems to me that the error can cause code (line 1008 in DBRFX.CPP file):
............
pFX->Default(szName, &value, plLength,
SQL_C_CHAR, value.GetLength(), nMaxLength);
..........
While debbuging program nMaxLength has value 255, but I do not know where gets it from.
And what can I do.

Hi,
is there any way to set property of a folder as zip-folder?
I create a new folder using CreateDirectory() for some data from my program, and set this folder as compressed, now i need to set this same folder as zipped folder!!
I don't want to create first a zip file and add some files to them, i create a compressed folder with CreateDirectory() and add some files to them,
and now i like to set them as compressed(zipped), is there any way how to do this?? Any idea how to do this??
Thanks for any help!

Feel free to correct me but...
There is no such thing as a "zip-folder".
There are normal directories, and NTFS can compress files in it. You gain space, and lose time.
There are zip files. Explorer very kindly has an already installed shell extension which makes them look a lot like a directory. Explorer is lieing to you, in the interests of ease of use. This is good.
I can't really help you, as it sounds like you already know how to do this, you just don't like it.
Did that make sense?

Hello Ian,
thanks for answer.
I don't know how to do this, if yes, i will never ask something here, the time is to expensive for that!
You know that, when you make a right mouse click on a folder or file in explorer, its open a menu, and one of choices is "Send to archive" (or similar, sorry about my english),
that is what i mean!!
If this don't work, i know here is a Zip Utils that i can use, but i like to try this first!
I can only show my try, its like this:
DWORD dwFileMask;
long mask;
dwFileMask = GetFileAttributes(csCurFolder);
mask = dwFileMask;
if(!(dwFileMask & FILE_ATTRIBUTE_ARCHIVE))
{
mask = dwFileMask | FILE_ATTRIBUTE_ARCHIVE;
SetFileAttributes(csCurFolder, mask);
}
but thanks for your help 
Arrin

The archive attribute for a folder is used by backup programs - it's not the same thing as a zip file.
There are zip library articles here on CP. I don't know a specific one to recommend, but CP is searchable. Once you've read several, you will know more than me about them.
1/ So, make the files you want. Put them somewhere temporary.
2/ Make a zip file containing those files. <-- this is the hard bit, but look at CP articles.
3/ Delete the original temporary files.
The right-click thing in explorer is a context menu extension, and just does step 2 above.
Good luck,
Iain.

Hi Guys,
I am having an issue with vsnrpintf() function.
My function posts an error message by formatting it using vsnprintf()
Ex:
void SetErrorInfo(const CHAR* lpzformat, ...)
{
va_list();
va_start(vargs,lpzformat);
_vsntprintf(szbuf,MAX_PATH,lpzformat,vargs);
}
This is crashing when i dont have arguments passed to this function and the formatted string has "%n" or "%s" which are known place holders for BufferOverflow.
Can anyone let me know if i can get a count of vargs argument list and based on that decide whether to use
vsnprintf() or not?

shriniwas1985 wrote: This is crashing when i dont have arguments passed to this function and the formatted string has "%n" or "%s"...
This is a side effect of variable argument functions like printf(). You can have more arguments than % in the formatting string, but not vice versa.

Hi,
That is very much true, but cant we have a check on the arguments, as in if there are no arguments and the formatted string has %n or %s, then instead of vsprintf() simple sprintf(buf,"%s",lpsformat); can be called.
Atleast that solves the problem.
But i am not able to find the count for no of arguments.
|
|
|
|

I think it is not posible to avoid such error in generally.
Because we cannot detect argument count for function(format, ...) at execution time.
Uncertain ideas here.
1. Always pass some constant which has reserved pattern which indecates the last arg.
2. Use try-catch block defined in c++.
3. Use SEH (__try-__catch) defined by MS.
4. Abandon f(a,...) style function. 
|
|
|
|

Even if you count them yourself, so what? You still can't pass, say, a 1 for a %s parameter and not have it fail.
I have a safe format function which is basically the following (with more error and exception processing, but this gives the gist):
__try
{
return _vsnprintf(pBuffer, bufferLen, pFormat, args);
}
__except (EXCEPTION_EXECUTE_HANDLER)
{
Copies raw format string into buffer
}
