yeah,
it's better, but it makes no difference between
waterlevel&rainfall
and
waterlevel&mudSand
Is there and other data type instead of enum can help fix the problem?
Thnx

That should be
waterlevel | rainfall (which = 3)
and
waterlevel | mudSand (which = 5)

Hi,
There is a limitation, right? Max number of item inside enum must less than 32.
In case that happens, how to deal with, then?

You'll have to use another int or a double if you want more than 32 bits. The number of items can be up to 32 not less than.

Only if you define the enumerator values to be one bit each, as in:
enum HydroElement
{
waterlevel = 1,
rainfall = 2,
mudSand = 4
};

If "waterlevel and rainfall" is a distinct type, make it so.
It however seems odd to mix waterlevel (measuring a distance) with rainfall (a weather phenomena) and mudSand (which is a particular type of sand, or mud depending on how you look at it).
Maybe it could use some more design before implementation?

Hi,
It's about hydrology, something relative to water system, where sensors are used to measure the water level of a river or a reservior. Other Hydro element includes rainfall, flux, sediment, water quality, flood warning etc.
In this system, GIS is used.

OK. But what is it you want to explain/quantify with this bitset/flags/enum/whatever-it-becomes? The types of sensors present at a particular station? The stations "purpose"?
If this data is to tell what types of sensors are present, and it just happens that there is more than 32 possible sensor types, what about creating an enum of (not as bit-flags, but as simply counting upwards) and put them in a collection (e.g. std::set, vector, ...)?
If you have 32 < nTypes <= 64, you could use a (non-portable) unsigned __int64 data type, but then an enum is out of the question (MSVC6 is unfortunately hard-coded to use 32-bit enums no matter how small they are - I don't know if VC7 allows >32-bit enums).

i may get the value of lparam from these function
long MouseX;
long MouseY;
MouseX = (long) (lParam & 0x0000FFFF);
MouseY = (long) (lParam >> 16);
//////////////////////////////////////////////
may i set different x an y values at the exect lParam's
location ?
if yes how ?i need syntex ?

What are you asking ? You want to put in a new location ? I don't think that will set your mouse position for you, in fact I'm sure of it. But you can use MAKELPARAM to join two values into a suitable LPARAM value.

Hi.
Does 32-bit Windows console support multithread programming? For example, is is possible to use _beginthreadex(), WaitForSingleObject(), and CloseHandle() in a 32-bit Windows console program?
Thanks,

Yes. #include <windows.h> and you're away.

Yes, and the best part is that normally you won't need the MsgWait* functions, only the normal Wait* functions

OputputDebugString outputs its message in the Visual Studio debug window: Press F5 to launch your program, click on Visual Studio and look for it --usually a lot of "foo.dll loaded" messages appear right at the beginning of execution.

hello @all,
i have a vc++ MDI programm. in this i need a dialog box. the dialog box is not the problem. my problem is the placing of it. is there a way, how i can place the dialog box in a corner (at the bottom left hand corner).
thanks

In OnInitDialog() your Dialog, uses MoveWindow or SetWindowPos functions for move your dialog
Best regards,

can you give me a example how i can use the function "SetWindowPos" ?
I must place the dialog box in a corner (at the bottom left hand corner)forever and ever.
thanks
lucky

|

You're must get the coordinates of a corner and then ...
SetWindowPos(HWND_TOP, x, y, 0, 0, SWP_NOSIZE);
Best regards,
