Hi ,

I have a CStringList that contains some filepaths, these paths need to be passed into a function:

eg: GetNewXML(LPTSTR PreviewFileArray[],int count)

How can I construct a LPTSTR array from CStringList?

thanks

Are you sure that you really need LPTSTR (don't you need LPCTSTR)?
As stated, you probably have to copy all the strings.

sorry, what do you mean "copy all the strings. "?

can you provide me a code? thanks

Yes the function prototype implies such copy.

however, I can't initialize the array like this:

LPTSTR[] files = new LPTSTR[count];

do you mean copy character by:
LPTSTR a = list.GetAt(0).CopyChars?

change to

LPTSTR* files = new LPTSTR[count];

Or another suggestion (if you can change the function signature): just pass the string array as a constant reference instead.

void GetNewXML(const CStringList& myList);

You wrote the GetNewXML function ?

sorry that I can't change the interface for function "GetNewXML", coz it has been written by pervious staff.

so I trying to do, but not work

/*
LPTSTR[] files = new LPTSTR[count];

for(int i=0; i< count ; i++)
{
files[i] = bmpList.GetAt(i).GetBuffer();
}
*/

Well, in principle, you can do the really weird thing you suggested:

LPTSTR* files = new LPTSTR[count];

for(int i=0; i< count ; i++)
{
  files[i] = bmpList.GetAt(i).GetBuffer();
}
GetNewXML(files, count);
for(int i=0; i< count ; i++)
{
  files[i] = bmpList.GetAt(i).ReleaseBuffer();
}
delete [] files;

I think you didn't really understand what the function accept: the function doesn't accept an array of strings, but one single string (and the count argument is the size of this string). So, you need to pass each string separately. Basically, what you'll need to do is loop through your string array, create a LPTSTR array of the size of the string and pass it to your function, then delete it.

That's completely stupid because if your previous team would have been smart enough so that they passed the string as a constant (LPCTSTR instead of a LPTSTR), then you wouldn't have to create a new string buffer, copy the string in it, pass it to the function and delete it. You would just have to pass the CString object (and it would have been automatically converted).

Oops, I forgot the [] after the first argument Unsure | :~

. So, forget what I said...

about this article: http://www.codeproject.com/KB/system/inject2exe.aspx[^]
can i resize the code section of a PE file?
for example: i want to add 100 bytes(fill with 0x90) end of the code section.
i change values of "SizeOfRawData" and "VirtualSize" for Code Section header. and i change values of "PointerToRawData" and "VirtualAddress" for next sections.

I would think you're more likely to get an answer by posting on the message board of that article.

For anyone here to answer, they'd have to know all about it, or download it and research it. The first is unlikely, the next is near impossible.

Good luck,

Iain.

What you are asking is extremely low level and involved. Not the sort of thing you can expect answered in a short message board post.
