I am accessing Files, folders, drives over network. Through SHBrowseForFolder I get the path over network. The problem arises when I check the path for validity with CFileFind.
Assume that there is a pc with name PCabc over the network, and it has a folder in one of it's drive with name FOLDER1, which is sharable, with the same name.
The path I recieve is \\PCabc\FOLDER1, Now when I pass it through CFileFind::FindFile() and CFileFind::FindNextFile(), the path is rejected. However if I take a folder say SUBFOLDER1 in the share FOLDER1 (which is also the exact name of the folder), I get no problem, ie, the path \\PCabc\FOLDER1\SUBFOLDER1 gives me no errors. It is accepted by CFileFind.
Can you suggest me what should I do to get the path for the shares which will be accepted by CFileFind.
Thanks

CFileFind::FindFile("\\\\PCabc\\FOLDER1\\*.*", ...); should work. If not, you'll need to step through the FindFile() code to see what it does not like.

Well, some of your choices are as follows:
1) Expose the SQL server to the internet and connect via the IPAddress as usual (Security NIGHTMARE)
2) Use RemoteDataAccess (requires IIS server and code changes)
3) Write your own Web server service that will authenticate the client and pass the SQL Statements on to the database behind the firewall.
4) VPN.

Hi all,
I guess this question will be easy for the windows expert on the CP, but I'm stuck with it.
Basically I enumerated all the processes on the system with PSAPI.dll's EnumProcesses.
Now from each process's HANDLE, I'd like to get a handle to its main window's HWND, in order to send messages using SendMessage.
How can I do that?
Thanks in advance,
Arnaud

One solution is OpenProcess(). Is one a reference from MSDN.

Hi everyone,
I'm pretty new to multimedia programming, have a task here that need expert guidance from you all  .
What I'm trying to do is to embed a mpeg 4 player into a MFC program I'm doing.
I'm pretty lost as to how to get started, I've read that DirectX is pretty useful for multimedia application in VC++. Should I focus on DirectX? Does it support Mpeg 4?
Thanks in advance.
Sincerely yours.

Probably not and No. I would do a search for ActiveX controls that serve that purpose. There are a couple of direct show media applications that will play your format provided you install a mpeg4 codec. A quick search on the internet and I found one at http://ffmpeg.sourceforge.net/[^]

yes, i'm agreed the above's suggestion, but here
i'll give you suggestion that you should learn the

I've created MFC application with Doc/View support. My view class is inherited from CRichEditView class.
I need to obtain the row and column number of the current cursor position.
The following function gets the current line number.
GetRichEditCtrl().LineFromChar(-1);
The question is "How can I get the column number"?
The ideal example is the Visual C++ IDE that shows the row and column of the cursor in the status bar. The row and column updates whenever the cursor changes.
|
|
|
|

A quite complicated solution :
Use GetSel to retrieve the caracter number.
Make a loop on LineFromChar with parameter the character number, which you decrement until LineFromChar changes.
Then, the first number minus the final one should give you the pos.
long int i,j;
m_RichEditCtrl.GetSel(&i,&j);
i=(i<j?i:j);
long int counter=m_RichEditCtrl.LineFromChar(-1);
while(m_RichEditCtrl.LineFromChar(i)==counter)
i--;
long int pos=counter-i;

Got used that Microsoft Word underlines the errors in red?
Nice isn't it?
Well, when editing my C programs, the editor didn't do that. What a bore.
So, I decided to add that feature to the editor. It is very simple:
After some period of time has elapsed since the last key was pressed, save the text in a temporary file, and call the compiler to compile that file. Save the output of the compiler and parse it.
Do messages like "undefined symbol "xxx" appear?
If yes, store the line and position of the offending symbol, and when that line is displayed in the editor, underline the symbol with red.
Want to see it in action?
Download the editor with the associated compiler (no charge, no registration, no questionnaire to fill, no popups) from:
http://www.cs.virginia.edu:/~lcc-win32
It is a nice feature, that doesn't hide the fact that it is not Visual Studio of course. Maybe because of its small size this algorithm is at all doable. The compiler is small and very fast. So fast that can be used as a background compiler, running most of the time behind you when you type.
Is C outmoded?
Yes, of course. C will be always outmoded because it is not fashionable. As languages come and go away, C remains. If you write in C there is a bigger chance that your code will run in the unknown machines of the future.
You probably know C. It has be cloned a thousand times, in all tones, even in the C Sharp scale.
The whole download is 3.5 MB. And there is packed a system with all the headers and import libs to use the full Win32 API. The editor, including the debugger, the project generation facility, a versioning system, a software metrics module, an object code analyzer, etc, is 700K.
Yes. 700K.
Including a spell checker for C.
I noticed that the latest versions of Visual Studio show the current function at the top right corner of the window. Lcc-win32 has been offering this since 1999 but it shows it at the bottom right corner.
But this is publicity, and is therefore biased. Look for yourself, and tell me if you like it.

Yes. As the above poster suggested, please write an article and post it in the free tools section. That way your article will get seen by more users. A post in a forum will only be good for a few days because no one will scroll ahead more than a few pages of posts.

I want to add the flexibility to my application to allow the user to write and use custom functions within the application. The functions would be added to a library. I don't want to write an interpreter. One thought I had was to let the user write C functions and write them to a dll source file, then my application could shellexecute a compiler and linker to generate the dll. The application could then turn around and call the dll function. All of this would be transparent to the user.
Now for the question. Can the VS C command line compiler and linker be shipped with my app?...I think I already know the answer, it would have to be licensed.
Is there a suitable free-ware compiler and linker that I could use?
Is there another way to skin this cat?...I don't want to try a VBA interface, but that might accomondate the largest audience.

The lcc-win32 compiler system does just that. Many people use it exactly for that. Their users type a function, then it is compiled to a dll and loaded into the system.
Lcc-win32 has also the possibility of loading an object file "on the fly", not a Dll. This eliminates a lengthy link step, and links the code "live" to the system. But that algorithm has other drawbacks. The dll way is more portable and is not so much longer to perform.
The interesting thing is that your users will say they want to debug their functions. The lcc-win32 system features a debugger too.

I am about to install the lcc-win32. I am a little leary of installing things. Will the program steal any of the file associations from VC?

No, the VC compiler cannot be shipped with your product, unless you bundle in a copy (license) of VC.
A few options include:
1) gcc compilers (free)
2) Using the Script Host to support users writing in javascript and vbscript
3) embed your own macro language (I have done this in the past and you will want to avoid this if at all possible!)
4) programmatically post the user-entered code to a service on your web site, compile it and return the DLL as the result (or error page)

These have possibilities, I will have to look into them.

Can't say I much like the idea of "end-users" running compilers etc. unless they are technically competant, and even then this doesn't sound right.
Using the Scripting Host is one solution, then users can write in JScript, VBScript, Perl (heaven forbid) etc.
Another is a C Interpreter, which is what I do in ED (see sig). Have a look at UnderC http://home.mweb.co.za/sd/sdonovan/underc.html[^] I haven't actually used this, but I'm suitably impressed with what Steve is doing.

I would be interested in your reasons why. The app would take care of setting the proper compiler and linker switches and report any errors generated by either. how is this functionally different than running an interpreter? I am not arguing with you, I never miss an opportunity to learn new things.

Thanks for the link...looks interesting, but I am worried about speed. my program, among other things is doing rather large monte carlo dispersions. I have the same concern about the scripting host
