I have a (mostly) peer-to-peer application that uses windows sockets to communicate with a server and also has it's own web server to serve up information to other peers.
This all works perfectly until users put themselves behind a firewall/router/etc.
As far as I understand (see disclaimer above), a user can use a SOCKS 4/5 proxy server to gain access to the outside world for this kind of application, but the P2P application needs to be SOCKS compliant.
- Is this true?If so, what do I need to do to make my application SOCKS compliant?
- Do I need to make any changes to the server application?
Your help, assistance and guidance would be gratefully received.

Im using mfc's hotkey control. I can get the key and modifier by doing this:
WORD v_Key;
WORD v_Modifiers;
m_Play.GetHotKey(v_Key, v_Modifiers);
Now how on earth do I put this information into a char* so I can save it in a file.
Then once thats done how do I convert the string back to the WORD? eg do is do this (assuming the value of v_Key is in charstring):
v_Key = (WORD) *charstring;
If someone could point me to a tutorial that would be great

Depends. If you need it in a readable way like "A" + Alt+Shift then it's not that easy.
If it doesn't have to be saved in a readable way, why not storing the 2 words as they are? Just save the 4 bytes raw to the file. Loading is easy: just read the 4 bytes and copy them back to the 2 words.
If it has to be an ASCII string then I would convert the words to their numerical strings (100 -> "100") and save that string (use function itoa). To convert it back, use atoi.

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

I programme using Visual C++ 7 on Windows XP but would like to develop code to run on a minimum of Windows 98. I am confused on what modifications (if any) to make to the stdafx.h file.
Below is the text from the define part of the file.
#ifndef WINVER
#define WINVER 0x0410
#endif
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0400
#endif
#ifndef _WIN32_WINDOWS
#define _WIN32_WINDOWS 0x0410
#endif
#ifndef _WIN32_IE
#define _WIN32_IE 0x0400
#endif
Thank you

I don't know what to tell you about your header file but,
you could actually do that by calling GetVersionEx to find the windows version your program is running on. If it's not the version that you like, then display a message and close the program.
However, my impression is that you want to do this because you want to make sure that a feature is present in the operating system. I read an article once about this and the only suggestions that I remember were to use LoadLibrary and then GetProcAddress to find out if certain functions are present. Also, you can use GetSystemMetrics for other features that you might be interested in. And finally you could use DllGetVersion. I am sure that there are other people that have more to add to this topic.

Thanks a lot.
I just want to ensure that my programme would run successfully in Windows 98, Me, 2000 even though I develop the codes on a Windows XP Machine.
Looking forward to getting a reply from you.

I am sorry. I thought you were asking about how to determine if your program is running on the correct windows version.
I really don't have an answer for your question. Usually when I use a function that is kind of new to me, I check the minimum OS requirements for it. Sorry, I can't help you.

I'm able to shut down, log off or restart windows by using ::ExitWindowEx, but don't know how to implement the "Lock Computer" feature which windows2000 has, any help appreciated.

First of all, thank you for providing the API name so I have some keyword to type when I start searching...
Second, I guess I need more help my compiler(vc++ 6.0) insists that "LockWorkStation" is an undeclared identity even though I have specifically(unnecessarily) included "<winuser.h>" which according to MSDN should be where "LockWorkStation" was declared, still got "undeclared identity". Maybe I need to install newer plateform sdk or something?
Thanks.

That would be a good idea
It is available with the files that come with VC6, but you need to #define _WIN32_WINNT (0x0500) or higher before including winuser.h.

Operating System: Windows XP Language: VC++ 6.0
Does anyone know of a good method to scroll images into a window (similar to how PowerPoint scrolls slides into view during a PowerPoint presentation). In particular I'm trying to develop an application that:
1. Loads images from disk and stores them in memory.
2. Scrolls a previously loaded image onto a window (bottom to top) at a configurable speed, over the top of any image that is already there.
3. Keeps processor usage to a minimum
I've done some experimenting with GDI+ using Graphics::DrawImage() to redraw the image onto the screen a couple of pixels at a time but it sends the processor usage on my computer up to 100%.
Regards
Martin

I use GDI+ and use FillRectangle() with a TextureBrush - it's considerably quicker than using DrawImage(). I haven't looked at the processor usage, but I think it would be much less - it doesn't have to scale the image like DrawImage() does (unless you specifically tell it to).
Hope this helps,

 I might try that myself. Thanks for the tip.

You're welcome
I can't remember how I found that out. I think I just experimented

Is there priority when you set Background,
Foreground and Fog color?
I made Background & Fog the same color, but
I can't change the color of object drawn in the 3D space
When I change the color of background, this object color
changes as well. It wasn't problem before I insert this
fog function. Any Idea?
Thanks for help

call glColor[X] before calling the glVertex[X] functions!
Don't try it, just do it!

Thank you very very much. I've searching for this answer.
It worked this time. But Do you know why?

Hi!
I write a image processing algorithm library in c++. Now i try to port it into a com dll server, in that way we can use it outside c/c++ environment. Then i can sell it to the developers of vb or c#.
But there is a problem, how can i protect it. Users of my client's application should not directly use it in their own development.
I read in msdn, and know activex control has a license engine (use lic file?). Is COM dll server the same as activex control (i really puzzled in this)?
Is there some method to protect it besides controlling document of library and some law warning?
Thanks!

ActiveX controls let you develop controls based on the Common Object Model (COM) that can be installed in dialog boxes or any ActiveX control container application. An ActiveX control is an COM-based object. Therefore the article that you read on the lic file should apply to your com server (is it, MFC ActiveX Controls: Licensing an ActiveX Control?).
In my opinion you could try to protect the dll by distributing one version for the application and another one for the developers.
To protect it you can have the initialize functions such as CoCreateInstance perform a license check before they return anything. The license key can be generated internally by the dll (i.e. have a function that generates a key based on some hardware numbers). You know that is not a topic that can be discussed with just a few sentences. So I will stop here. Check out some packers that can protect your software and that way you won't have to worry about implementation details.

I've been looking at a mass of spagetti code (which is supposedly an MFC app) from one the other monkeys here which for some reason has a dependency on msvcp60.dll. All our other MFC apps dont have this dependency - they only require mfc42.dll and msvcrt.dll - why this one?
|
|
|
|
|
msvcp60 contains classes such as basic_filebuf, basic_ios, etc. that start with the word basic_ (those are the ones I recognize at least). Those are not the only things in the dll, there are a lot more functions and classes. Try to use dumpbin /exports to see all the functions that are being exported.
I just had another idea. Remove msvcprt.lib (that's the library I believe) from the linker's options and you will get a bunch of errors telling you that you have external dependencies missing. That way you will be able to see what functions in the source code are linked to msvcp60.dll. I hope that makes sense.

Halo,
I still have some problems retrieving the selected data from a list box,
I showed my earlier code which was wrong, and got some ideas from a friend from this site and as suggested by him I used the function LB_GetItemdata.
Here is the code
void Cdlg4Dlg::OnDone()
{
HWND w=GetDlgItem(???? ,IDC_LISTBOX1);
LPARAM j=SendMessage(w,LB_GETITEMDATA,0);
}
so the GetdlgItem returns a handle to the list box, but i dont know what to be put for the first parameter (????).The MSDN site says that it is the handle to the dialog box containing the list box, how do i get it..can i put the id of the dialog box?? )like IDD_DIALOG1..
and another doubt..Will 'j' be the data which is selected in the list box or will that be a differént one..if thats not going to be the data selected , then how can i get the data (a number in my case) selected from list box be stored in a local variable?
some example codes will be helpful..
My question might be too stupid, please excuse since I am beginner..
Thanks,
Deepak Samuel
