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);

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

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.

thanks !
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
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:
You want to create "dialogs" that look like "buttons?"

For make a dialog you can use of CreateDialog it makes a modeless dialog box.

VS is unable to locate the DirectShow library, probably Strmiids.lib

I have a project using DShow.It works well in VC6.
But when I convert it to VC2005,some errors occur.
Especially,a error like this:
1>d:\program files\microsoft visual studio .net\vc\platformsdk\include\winnt.h(222) : error C2146: syntax error : missing ';' before identifier 'PVOID64'
I thinks there is some wrong in the configuration of the DirectX(9.0b).
Someone would tell me how to config it and correct such error?
Thanks

The error has been resloved.
But another error occured.
It said that could not find such external :
_CLSID_VideoInputDeviceCategory
error LNK2001: _CLSID_SystemDeviceEnum
error LNK2001: _IID_ICreateDevEnum
How to resolve it?
Thanks
