creating a SOAP-Server with gSOAP[^] is pretty straightforward.

For you client, you could then use a crippled WEB-Gui, which is so fancy these days, or a real client written in almost anything.

Failure is not an option - it's built right in.

what im trying to do is on a keystroke it +1 to an int and on my dialog im just trying to print the value in a static text box

To format a string for an int, you could use sprintf() (or similar) with %i/%d (signed int) or
%u (unsigned int), something like:

// generic - works for unicode and non-unicode builds

int MyInt = ...;

// get string representation of MyInt
TCHAR IntString[16];
_stprintf(IntString, _T("%d"), MyInt);

// set the static control text
::SetWindowText(hwndStatic, IntString);

plotting in real time

hi!

i have a visual c++ prog which gives me value( dist ) which i have calculated.The value varies between 1-5.( i.e not a lot ). I want to plot this in real time. Maybe just a simple bar which changes size as this would be much more eaasier than a graph as it would need scrolling.
Any one have a code for this ??or a suggestion
Thx !

[code]
LONG FAR PASCAL
MainMessageHandler(HWND hWnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
HDC hDC; /* handle for the display device */
PAINTSTRUCT ps; /* holds PAINT information */
TEXTMETRIC tm; /* holds TEXT information */

static HRGN hRgn; /* Rectangle region Handles */
static int CharWidth, CharHeight;
...
...
...
y += CharHeight*2; /* Print raw data value */
sprintf (OutString,"dist = %lf ", dist);
TextOut(hDC, x, y, OutString, strlen (OutString));

}

[/code]

thanks!

To draw a bar you could use something like FillRect().

Can you be more specific about what part is giving you trouble?

thanks for the reply.
To be honest, i have no idea how to start the plotting. The only thing i have now is my value which has to be plotted ... The book which i have doesnt say anything about real time plotting

Mark Salsbery15-Jul-07 9:51

How you plot depends on what you want to see...

You showed what looks like a window procedure - Is the value being delived at regular intervals
through a window message?

The basic steps for drawing to a window are:

Create or obtain a device context (DC)
Set up the DC for drawing - select the appropriate pen/brush/font into the DC
Do the drawing
Restore the DC's original pen/brush/font
Free the DC

You can do all this in response to the WM_PAINT message.

When the value changes, invalidate the rectangle or region that you want redrawn and call
UpdateWindow() to force a WM_PAINT to be sent immediately.

yes i am already having a bunch of cases. I get out about 10 values per second so its really current. I give out the value right now in WM_paint.
i shpuld read up on the deice context!

Thanks for the reply ..

Yes, definitely! Also check out the BeginPaint()/EndPaint() APIs for obtaining a DC when drawing
in response to WM_PAINT.

No such thing IMO - misworded maybe Smile | :)

You can add buttons to the dialog resource or

CreateWindow()/CreateWindowEx() can be used to create buttons on an already-created dialog.

For the appropriate window class to use when creating controls, see
Windows Controls[^]

Come on, Mark. Put your double-quote fingers up when you ask those questions:
