you don't happen to remember WHY I must use overlapped do you? I have a serious problem with what I thought was going to be a simple app.

Any chance you have a little time you might be able to lend me? I have a program that I'm having problems with. I'll leave the details dependent upon your response.
thanks

Lets say I have two extension dlls Dll1 and Dll2 and an Application MyApp. Now following is the scenario.
Dll1 uses Dll2.
MyApp requires Functions from Dll1 and some functions from Dll2.
Now the question(s)
1) In case of Extension Dlls , where does this Dll gets loaded? withing the memory space of MyApp ? or outside the memory space of MyApp ?
2) Since Dll2 is used twice , a) directly from MyApp, 2) indirectly through Dll1. So is it going to cost any how on performance ? in terms of memory or any other way ?
If yes then what should be the alternative ?

No, the OS uses memory mapping. Each DLL is loaded once into a global memory space and then the required DLL memory is mapped onto the applications process space. So no matter what you do each DLL will only ever be loaded once.

I have to implement a list that stores 2 strings and a pointer.
I have created a struct that hold this things:
struct TEST
{
CString s1;
CString s2;
int* pInt;
};
The struct holds the 2 strings and a pointer.
(CString because it's easy to handle in UNICODE and non UNICODE systems)
As next I have created a list with the STL vector class:
vector<TEST> myArray;
So, I can work very simple with my struct (example):
for (...)
{
TEST t;
t.s1 = _T("string 1");
t.s2 = _T("string 2");
t.pInt = NULL;
myArray.push_back(t);
}
Do you think it's a good implementation or is there something I could do better (memory, make something faster, ...) ???

reserve() memory for elements or you have lots of (expensive) relocations. alternatively you can use a std::list.

Did you remember to call AfxOleInit( ) or CoInitialize( ) at startup?

Hi,
I have to make an COM component with ATL, that needs some fancy GUI interface, it seems that WTL is the best thing to develop something cute and lightweight, but.... I'm wondering... Why Microsoft doesn't support that ? Is there something wrong on there ? Would be a better idea to try to make it with .net framework and forget ATL ?
Thanks in advance, Greetings

They never supported WTL.

The questions here are: do you use MS support? Will you use MS support?
How long does this project will last? If a long time project, IMHO, don't use WTL, or you'll be using VC 6.0 in your 22GHz 128-bit processor in 2008, running Microsoft Linux.

Yes you are right, now we in some part of the project tied up to the VS 6.0, I would'nt like to tie me up to that....
Thanks for the tip, greetings

Eh? Misinformation! WTL isn't compiler specific so your comment about having to stick with VC6 is incorrect. WTL is a bunch of templates in header files - works fine in VC7 and there is no reason that it won't continue to work with future MS compilers. The guy is using ATL so WTL is surely the obvious choice for adding a GUI.
MS Linux. he he he.

Try to compile some old DOS C++ code with <iostreams.h> on VC7 to generate a console application and you'll soon understand what I meant. I did it last week. On the long term, unfortunately, if MS does not support WTL, it will fade away, and probably will not compile on VC12.0

Mmmm. As long as MS continues to support ATL (any reason why they would stop?) then there is no reason for WTL to stop working. And, looking at how rich ATL7 is, MS is still very much behind it...

Why do you need MS support for it? You get all the source code so any bugs can be fixed yourself. WTL has a large user community who can help better than MS ever would. WTL is great for adding UI to ATL components.

WTL works just as well in Visual Studio 7, I use it all the time!

There are two versions of WTL, 3.1 (which is easy to use with VC6, and has an AppWizard for it), and WTL 7, which is usable with both. I'd go for WTL 7, since there are appwizards for VC6 and VC.NET

Just add the right mimetype in your HTTP headers :
Content-Type: image/jpeg

We've created an application that uses Winsock API. Now i want to create a separate application that intercepts the Connect() call made by the first application, do something with this call and then pass the control to the original Connect() of the Winsock API.
Is this possible ? Is this the topic of API hooking ?? Is there any other altranative to achieve my goal ?? Is there any article or sample source concerning this topic of Winsock API interception, you aware of ???

It did that already a few times, it is possible, and: It is very easy to accomplish
I use the Microsoft Detours library for that purpose, although it has some limitiations in it license. Take a look at
http://research.microsoft.com/sn/detours/
The libarary has a few examples, and I learnt to use that library withinh a few minutes
