One doubt. if your using a 64 bit mechine, are you sure the above shifting is correct?. I found the original code was written for 32 bit mechine. Also confirm the TEB have same size in both 64 bit and 32 OS. Expecially in VISTA.

It may be a 64bit machine, but the exe is 32bit. Also, if you look at the code, before accepting the entry point, I check the PE headers to validate that it points to the correct location.
As far as this project goes, I'm going to have to give up, at least until I install VmWare. For now I will stick with being able to run only console apps, which is the main reason I started this.
The strange thing is, every single article I have found on the topic is the same as my code. I have played around with the TOKEN and SECURITY_DESCRIPTOR structs. But, when the initial pages are allocated for the process, they are done so with the PAGE_EXECUTE_WRITECOPY protection, and I can find no way around this.
I really must test this code on other machines to test if it is a Vista x64 'feature'!

BTW. Taking your suggestion of inserting the whole thing into a spawned process, but it requires a lot of work in the PEB and TEB headers.

hmm.. May be complicated..

My application is a MFC Win32 Dialog developed in VS6.0.
The dialog is used mainly for user input to parameters for a lengthy process called from a function within the dialog. I am using the windows UpdateWindow() method and Invalidate() from within the function to update the dialog indicating the number of records that have been processed and saved to a file. This seems to work correctly when ran on a Windows 2000 PC. but when I run it on a Window-XP PC the dialog is blanked with only the frame remaining whenever the application's focus is lost, by clicking on a desktop icon or launching an other application. Is there a solution to this problem? Could some sample code be provided to do this task?
Thank you.
Sample of my code follows:
<br />
while(!feof(In_File) )
{<br />
if(fgets(Sbuf,3000,In_File) != NULL)<br />
{<br />
rin++;<br />
DRec Srec(Sbuf, ',' , ',');<br />
Pn = Srec.Extract(m_uFieldNorth);<br />
Pe = Srec.Extract(m_uFieldEast);<br />
classNumber = (int)Srec.Extract(m_uClassField);<br />
<br />
Rn = Tn-Pn; Re = Te-Pe;<br />
<br />
RnRe = (Rn*Rn)+(Re*Re);<br />
<br />
if( ( RnRe ) <= Trr )
{<br />
fprintf(Out_File,"%s", Sbuf);
classCount[classNumber] += 1;
}<br />
}<br />
<br />
if((rin % 5000) == 0)
{<br />
SetDlgItemInt(IDC_SDataRecords,rin);<br />
<br />
UpdateWindow();
}<br />
}<br />
<br />
}
<br />

UpdateWindow() won't do anything if none of the window is marked for repainting.
Have you tried Invalidate[Rect]() before UpdateWindow() on the window or calling
UpdatwWindow on the control itself?

Wouldn't SetDlgItemInt() invalidate the window?

I would expect it to invalidate the control window (if it didn't draw
the text immediately), not the entire window.
I just tried to offer something to try.

My previous post was a test, and only a test. Had it been an actual post, it would have contained something intelligible.

If a make a call to CreateProcess() from within my code, is there any way I can break and start debugging the newly created process? Having no sources is no problem, I have become quite good at stepping through assembly.
|
|
|
|
|
in the VS Debug menu, you can use 'Attach To Process' to start a debugging session on the process you just launched.
|
|
|
|
|
I'm guessing the debugger needs an actual file on the disk to work with 
I'm getting "Unable to find file" error messages every time I try to attach.
|
|
|
|
|
it needs a running process - and a process needs a .EXE .
what file is it not finding?
|
|
|
|
|
Well, that's the thing, I don't have an .EXE
I'm launching a process from a file stored in the resource section ( NOT a file on disk ), so I'm guessing the debugger is looking for this file so it can display the assembly.

ah... in that case, you've moved beyond my sphere of knowledge

I've begun using C++ again after mainly using C# for the past several years. I was wondering what is considered the best way to pass a collection of objects to a function assuming the use of the Standard Template Library.
The function that's receiving the collection doesn't care if the collection is a vector or list or whatever, it just wants the objects. Is there a way to pass a collection that decouples the collection type, e.g vector, list, etc., from the function receiving the collection?

how does that work ?

Well, that's kind of the question I'm asking. What I'm doing now is this:
void MyClass::SomeFunction(const std::vector<SomeObject *> *collection)
{
std::vector<SomeObject *>::iterator it;
for(it = collection.begin(); it != collection.end(); it++)
{
}
}
The function just wants to iterate over the collection. If I were in C#, I'd pass an IEnumerable object. The function could iterate over it without having to know what the underlying collection is. I'm not sure how to do the same thing in C++ with the Standard Template Library.

ah. ok.
then, you would pass two iterators, a start and an end, to your function.
template < class _InIt > void DoStuffToIterators(_InIt _First, _InIt _Last)
{
for (; _First != _Last; ++_First)
DoStuff(*_First);
}
...
DoStuffToIterators(collection.begin(), collection.end();
that's a stripped-down version of STL's "for_each" function.

Oh, I see! Thanks Chris and Michael for helping me out with this.
|
|
|
|
|
You can model your code after the functions in <algorithm> - pass iterators marking the start and end of the sequence.

Is it possible to prototype a struct to allow a declaration of that struct in the body of the struct.
typedef struct<br />
{<br />
Node child[4];<br />
}Node;
The above code throws an errors as Node has not been declared. Can Node be used inside the struct Node?
Thanks for any help.

It is a little easier to do with a class than a struct, but you need a struct name rather than a typedef, and you need pointer references.
<br />
typedef struct stNode<br />
{<br />
struct stNode *child[4];<br />
} Node;<br />
The main reason you want pointer references is that every child would have children, which would have children, which would have children, which would have children, etc. A pointer is a fixed size.
