Hello,

<br />
double round(double Num, double Seed)<br />
{<br />
    double fac = Num / Seed;<br />
<br />
    fac = (fac < 0) ? (ceil(fac - 0.5)) : (floor(fac + 0.5));<br />
    // fac = (fac < 0) ? static_cast<int>(fac-0.5) : static_cast<int>(fac+0.5);<br />
<br />
    return fac * Seed;<br />
}<br />

round(3.7856, 0.001); = 3.786

Hope this helps.

Try this method

int nRoundFigure;
nRoundFigure = (int)( 24.58 + 0.5 ); // Answer will be 25
nRoundFigure = (int)( 24.34 + 0.5 ); // Answer will be 24

Hope this will work Smile | :)

How to disable the drag and drop operation in WebBrowser control

Hi,

I am using WebBrowser control to display the HTML help files. My html help files contains some graphics like jpg and png images. When user tries to drag and drop the items from the help pages the WebBrowser control gives debug assertion error. How can I disable this Drag and Drop facility?

I am also setting the RegisterAsDropTarget(VARIENT_FALSE)at runtime after the control in created, but still allowes to cdrag and drop the images.

How can I disable this Drag and Drop facility?

Regards,
Hemant.

   I do not know of any way to do this... If you can get notification of the D&D operation, you may be able to inhibit it, but I am not sure if the WB control gives you that information (easily, if at all).

   It might be worth finding out why you are getting the assert, and solving that problem.

   Peace!

hi,
does anyone know if I can record just, for example right channel using direct sound?
Is there any direct sound function where I select which channel i want to get.
thank you

Set the capture format to whatever multi-channel format you are capturing.
The recording format would be single channel of same sample-rate/bits-per-sample as the capture
format (you could, of course, convert the source samples to a different format as well).

The source samples for each channel will be interleaved. If capturing 2 channel 16-bit audio
you'd have two bytes left, two bytes right, two bytes left, etc. If you wanted just to record
just the right channel then just write the right-channel samples.

Make sense?

I have an app (that I've developped) running on my windows mobile PDA. When I have a wifi connection, it works a treat [*].

But I don't want my end user to have to use the wireless manager, make a connection, then switch to my app.

Is there a way for my app to kick off the wireless connection? I've done a ton of searching, and can't find an API.

I'm guessing its not quite as simple as WIFI_Make_Iain_Connection (), but a pointer towards the right API commands would be greatly appreciated. If nothing else, it would give me more useful search terms. Heck, sample code would be even nicer, but not necessary.

My next fun challenge is making a today page app to launch my main one....

   WNetOpenEnum(...)/WNetEnumResource(...)/WNetCloseEnum(...) may be easier if you only need the name of the shares available.

   Note that a share does not have a drive letter unless one is mapped (via NET USE) or subst (via subst) on the local machine - I believe a share server machine cannot dictate the drive letter a client will use to connect to it.

CDatabase's connect string

Hello,

If I have to provide CDatabase class with the connect string which gives me access to a database at the server or a PC then what should be my connect string (CString )?

What info about the PC on the internet should I have ex port address, IP address etc?

You can provide the connection information with either the CDatabase or the CRecordset object. A UNC path will be just fine.

I think you have to configure the proper ODBC first. And then provide the information in CDatabase::Open() function

So while configuring ODBC I will have to give the info about the Server and the database Is it?

Thanks for your reply.I will look into the detail of ODBC configuaration.

I'm using this structure while toggling my window between fullscreen and window modes. Now according to MSDN this is the definition:

typedef struct _WINDOWPLACEMENT {
    UINT length;
    UINT flags;
    UINT showCmd;
    POINT ptMinPosition;
    POINT ptMaxPosition;
    RECT rcNormalPosition;
} WINDOWPLACEMENT;

But my VS is showing an extra member RECT rcDevice. Great I thought, the monitors rect is given to me. But in winuser.h, this extra member is wrapped in a #ifdef _MAC #endif block. What does this mean exactly?

Having mac versions of a range of products doesn't necessarily mean that VS is able to build mac versions. Thats like saying VS builds will also run on linux ( with the exception of wine ).

VS isn't capable (to the best of my knowledge), but the header files are from the platform SDK, which is usable by other compilers. This way they keep a common source.

Dear All,
we are managing a very big ascii files that we should like to save in a DB as zipped file.
When user should like to know the content of the file I don't want to extract and save a local copy of the file, unzip and show to the user the content. What I want to do is to read the file and unzip it in the memory on the fly without saving it.
Does any one can help me ?

Thanks
