At the end of the day, how do you expect the web page to read the Access database ? Do you know anything about ASP or ASP.NET ? If not, then you're totally in the dark, and you've got a decent learning curve ahead of you. Your web server needs to be running IIS ( i.e. not just a directory of html files on your ISP provided web space ), and you need to write code to read the database, and asp or aspx pages to use that code and turn the result into HTML.

Hi Christian,

1) Might be you did not understand my request (or I wrote not clear enough), I do not mention about: the web page to read the Access database! Instead, I mentioned that: how my VC++ 6.0 can read the .mdb file on the Web page (at same Web-page location)

*) The reason was: I know (but not very good) how to use ASP to open the same .mdb file as I mentioned earlier! In fact, I already had an ASP application on the Web using ASP and it is able to open & access data from that .mdb file!

2) However, at the Client site (my personal PC) I have a VC++ 6.0 MFC application using very heavy programming!

*) It has one small option ---> requiring to get the information from the Web user in the same .mdb file who is using my Web-application ASP proram on the Web

- And I do not know: how to link to that .mdb by using only VC++ codes at the Client site

I hope that you understand my issue.

Thanks

ATC

In other words, your web application is moot, it is irrelevant. You want to connect to a remote database using an MFC app, in other words you need to write code to connect two applications over the web, to send requests and return the data. I'm sure you'll find that info here on the site, or in the MSDN.

SSL connection example

Hi, can anyone tell me where i might find and example/tutorial on how to establish an SSL connection with a server (not a web server, just in general..). I already know about OpenSSL but to be honest, i don't understand it, lol. So I'm talking something basic, hands on..

Thanks!

The examples that come with OpenSSL are as basic as it gets (I would even say that they are probably too basic).
Note that SSL communications can be really tricky and you really need to understand what is happening.
Trust me on this one.

Sorry to scare you off.
I only tried to explain that this isn't an area where you just slap something together and all works just fine.
Though, I should have mentioned that not everything about SSL is hard.
For example, writing a SSL-client using blocking calls and no clientside authentication is pretty easy.
Start off by going through the example that comes with SSL (try to ignore the IMHO bad coding style Smile | :)

)
and remember that they are taking some shortcuts that may not be approperiate for your application.

God luck!

ah! Faith again! lol
Thanks for the suggestions, i'll be sure to try it. But one more question, Is there perhaps something useful to learn before starting this, like something that would help me a lot understanding this. Or is it unnecessary? I know my way pretty well around sockets now so that shouldn't be a problem, but i was wondering maybe there's another field of importance, like for example encryption? I'm not sure but i just maybe thought that could be of some importance.
Anyways, thanks heaps Big Grin | :-D

Yes, some knowledge about encryption is a good start. Note that the thing you want to study isn't HOW the different encryption-algorithms work internally but what they require to function.
For example you need to understand what a certificate is, what a certficate-chain is, the role of a CA and the significance of its certficate.
Then learn about how SSL establishes the encrypted connection and how different settings affect how you need to initialize SSL.
Since I dealt with the subject it seems that the selection of books on the topic has expanded some:

http://www.rtfm.com/sslbook/[^]
http://www.wiley.com/legacy/compbooks/catalog/38354-6.htm[^]

And a short tutorial (haven't read it through so it might be crap...)

How to Overload bitwise AND operator

I need a simple example of overloading bitwise AND operator.

Atleast the signature to overload the bitwise AND operator.

Thanks in Advance.

are you talking about doing this for a class.....

class CDummy
{
  public:
    CDummy& operator & ( CDummy& rhs )
    {
      // do your stuff here
      return *this;
    }
};

That is untested.... it should work unless there is something funny about overloading bitwise operators compared to normal operators which i doubt.

I need some help please.

I am working on an application in which a DLL starts up a dialog box. This dialog box is started with a CWinThread I spawn specifically. After DoModal() returns the thread exits. The problem is that my application also uses an Ocx which does some image processing. Anytime the OCX blts something to the screen, the dialog box exits nad so does the thread.

I am not sure what is going on, Can anyone help please ?

Cant change mouse speed with SPI_SETMOUSE !

hi

i have been trying for bout 2 hrs to change mosu espeed with the floowing code and just doesnt work. Im using windows xp.

long speed[3], new_speed[3];

// Get current mouse speed
SystemParametersInfo(SPI_GETMOUSE, NULL, speed, NULL);

new_speed[0] = speed[0];
new_speed[1] = speed[1];
new_speed[2] = speed[2] * 2;

// Set the mouse speed two times faster
SystemParametersInfo(SPI_SETMOUSE, NULL, new_speed, NULL);

When i debug i can see that new_speed[2] is changing but it has no visual effect on the cursor. It just doesnt make any sense. When i go into control panel the speed is always the same!!

I could rerally use some help here.

Cheers Guys

Try using SPI_SETMOUSESPEED instead. SPI_SETMOUSE only sets the acceleration thresholds, not the actual speed.

Hi all,

i want to change the default file name that will be produced after the compilation. i.e , if i have an *.exe project and the name of the project is MyProj then the name of the output file will be MyProj.exe

i want to change the default name, but i am using code (I can't change it via project-->settings-->link-->general)....
i know there are interfaces of Object Model called IBuildProject, and IApplication and IConfiguration.......

can any1 tell me how to use these interfaces and change the default output file name????

thanks
Yaron

I use simple code, assuming that the only configurations will be debug and release

1/ Remove the old tool settings (I think you've got the basic idea, from the info in the question)
2/ Add the new tool settings to replace the ones you've removed.

// set the configuration number (debug / release)
_variant_t varj = j;
// work out if this is a debug build
BOOL bDebug = (BOOL) _tcsstr((const char*)outOpts, _T("Debug"));</br>
// remove the old output options
pConfig->RemoveToolSettings(linker, "/out:", varj);</br>
// load the new output options
_bstr_t outPath = bDebug ? "/out:Debug\\" : "/out:Release\\";
outPath += "foo.exe";  // set your new name here
pConfig->AddToolSettings(linker, outPath, varj);

Hi,

thanks for the help,

i have a question: how do i know it is Debug mode, i saw in your code:

// work out if this is a debub build
BOOL bDebug = (BOOL) _tcsstr((const char*)outOpts, _T("Debug"));

where do you get the outOpts???

thanks

// make a bstr
BSTR outOpts1;
// load the compile type (debug / release)
pConfig->get_Name(&outOpts1);	
// load into a _bstr_t (COM encaps ptr)
_bstr_t outOpts(outOpts1,true);	
// which configuration is it?
BOOL bDebug = (BOOL) _tcsstr((const char*)outOpts, _T("Debug"));

i want to ask you an other question, maybe you can help:

now that my appwizard is finished, i want by right click on one of my classes to do something (same as i right click on the project and i have a popup menu with the item 'New Class'....) what i want to do is to add my own entry to the popup menu......

can u show me sample code on how to do that please?

thanks again man

Not sure exactly - it's not something I've needed to do, but perhaps rather than AppWizard functionality you could you use a Developer Studio Add-in.

The link below is a new article, it's slightly different to what you want but it might get you going with Add-ins.
