Yes, because system and user DSNs are simply registry settings. If it's a file DSN (not recommended for an installation of course) you could include it in the install, but I wouldn't do that personally.
Were you looking for a yes or no answer or details as to which registry settings as well?

Can someone introduce to me a Autocad compatible drawing class library? I came across one at www.vdraw.com, but unfortunately, it is a ActiveX component. I prefer a C++ library that use MFC.
Thank you.

Then you'd need to search the web for the Word file format, and hope that it is organised so you can cope with all the different versions easily.

if((WM_KEYDOWN == pMsg->message ) && (GetAsyncKeyState(VK_CONTROL) < 0) && (VK_F4 == pMsg->wParam ))
{
TRACE("CTRL-F4 DOWN\n");

Kewl that you posted the answer.
But why is it that some folk avoid the PreTranslateMessage like the plague ?

I have added "myfile.exe" to the my project's resource. The ID for the file in the project is "IDR_FILE2". After that,I created a newly open file with CFile with the following code:
CFile newfile("c:\\test\\quest.exe",CFile::modeCreate|CFile::modeWrite);
Which ofcourse will create a blank "quest.exe" in the directory. But I want to copy "myfile.exe" in the project's resource in to the newly create file "quest.exe" Could you please tell me the exact code that do what i want?
Thanks in advance for your help

I guess you'd need to step over the file that is a resource, and write it's contents to the files. I could tell you how to do that with proper C++, but not with Microsoft's imitation classes.

Does the file contain text only, or is it binary data, like an image ?

The file is a binary executable (.exe) and i want the newly created file be able to execute as well. And could you show me the code for text file too please.
Thank you so much for your help.

The part I'm not sure about is stepping through the original file object. I'll have a look tonight and LYK. Otherwise, a text object is easy.
std::string sObject; // Has been set to the text of the file
std::ofstream aa("c:\\myfile.txt");
aa << sObject;
aa.close();
You need to #include <iostream> and <fstream> and then that would be fine. The file can be opened with ios::bin as a parameter to be in binary mode, but unless you have a method of stepping through the file object, that does not help much. I'll do some research.

I have compiled the boost library (specifically the regex++ portion), and have successfully used it in a test app in VC6. The problem is, that im getting no Intellisense (and I am using VisualAssist), and it is quite annoying. Its a small issue, but I am wondering what directories need to be included in VC and where I need to add those directories (I tried Tools:Options). Any suggestions?

I am trying to enumerate through all the process on running on my computer
so I can run through them and get a handle to the process using OpenProcess()
const DWORD dProcessCountGuesstimate = 200;
DWORD ardProcessIds[dProcessCountGuesstimate];
DWORD dNumberOfProccessFound = 0;
BOOL bReturn;
bReturn = EnumProcesses(ardProcessIds,
dProcessCountGuesstimate * sizeof(DWORD),
&dNumberOfProccessFound);
My question: Is there a better way other then guessing the number of process running on my computer. It kinda seems retarded to do it this way. Could someone please help.
Thanks.

The problem is that the process set is very volatile. Processes get started and stopped very regularly, without user intervention. Even if you could determine immediately prior to calling EnumProcesses how many there were, there's no reason to believe the count will be the same by the time EnumProcesses executes. So, just make a wild-ass overestimate of the count, and hope for the best. I'm sure that with statistical analysis, you could determine a value that has a 99.99% probability of being sufficient. But memory is cheap, right? Make your best guess at how many there will be -- and double that. Even if you allow for 1000 processes, that's just 4000 bytes.

I have a strange problem that I am not sure where it is coming from. I have a program (GUI) that runs fine. I added another Form to my program and put label etcs on. All my labels I have made a label class to customize the behavior. As such I subclass all labels and such on all forms I make. And I have a lot of forms in my project.
OK. Today, after I added ONE single extra label, the system runs fine but when I exit, it gives me an access violation error.
What I want to know, is there a limitation how many controls there are in a project? Is there a limitation how many BRUSHes etc that I can create? The reason is that I have CBrush variable to hold brushes of all sorts in these so that they can change the bkgnd etc at will in the Ctlcolor function.
I hope someone can help. This is just driving me nuts.
Thanks in advance.

Yes, there is a limit, but it is quite large.

hi all,
i am trying to write a client to connect to a non-mfc application thro' network. i am just at the beginning, i found that CSocket approach only support connecting to mfc application as the CArchive used. is it true?
would you recommend using winsock api or start from CSocket to connect to a non-mfc server? i don't have too much idea about these. pls try to give me some idea!
thanks,
jim

I'm actually going through a similar situation. And I can tell you that CSocket will not connect to a standard socket connection. If you use CSocket, you have to use CSocket throughout. If you can't use CSocket on all ends, use basic sockets. There's quite a bit of info out there.
Programming in binary is as easy as 01 10 11.

Hello, the codegurus around the world.;)
As the previous poster pointed out, CSocket or CAsyncSocket class
is closely related to GUI by MFC.
So, if you don't need to use MFC, you don't need these classes at all.
(In fact, WSAAsyncSelect function is inserted some messages like FD_WRITE
to Window message process at CSocket and CAsynSocket)
As a result, WinSock API is best choice for you.
Please, don't send me your email about your questions directly.
Have a nice day!
