This produces the same result as if you had right-clicked the file in Windows Explorer and selected Print. I do not know of a way to circumvent the Print dialog box.
My first guess would be an SDI application that used a CHtmlView. You could then programmatically print whatever was in the view.

i use serial communication both two class.
first,i open com port from one class for receiving data and displaying data in the dialog.
and i receive data from com.
this is fine work..
samelly,i open com port from another class in my application for displaying another format in another dialog.
in case, i have problems.
it doesn't work.
i have not receive data from com port.
i want to know
can i open same com port(eg:com1) in both two class within one application?

No, you can only open a COM port once. So, you'll need to share the handle of the port to be able to read/write data from another class

Hi
I´m quite new to VC++ .NET, and I´m building an application that is going to display graphically the readings from a sensor.
What kind of container (if container is the right word) should I use for displaing the graph?
Appreciate any suggestions,

We found that NTGraph controls (below) were fantastic on my last project. Very easy to use, easy to control and lots of functionality. If all else fails you could always save out as comma delimited files and use excel or excel automation as an alternative.

I have a CToolbarCtrl with an CEditControl and a CComboBox in it.
In order to have a tooltip for those controls I added ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipText)
to the toolbar. This solution worked fine until I added Manifest to the application.
With manifest I don't get the wanted tooltip. OnToolTipText doesn't get called.
Does anyone how to solve this problem?

On top of what, all other windows in your application (this is a modal dialog), or all windows in general (this is a system model and is used only in extreme cases)?

Hi everybody,
i've been having a strange behavior of the sscanf() function, which i replaced then by atof() (that works fine now).
i would like to repport this here to see if anyone has already encountered this before, and if any explaination was posted...
here is a sample of the code :
CString strVersion = <font color=#808080>"2.05"</font>;
<font color=#0000FF>double</font> dVersion = 0;
<font color=#008000>
sscanf(strVersion, <font color=#808080>"%f"</font>, &dVersion); <font color=#008000>
dVersion = atof(strVersion); <font color=#008000>
TOXCCT >>> GEII power
[toxcct][VisualCalc]
|
|
|
|
|
As indicated by the "%f", dVersion should be declared as a float and not as a double.
|
|
|
|
|
false.
%f is for both floats ans doubles
TOXCCT >>> GEII power
[toxcct][VisualCalc]
|
|
|
|

You can either change dVersion to a float (not recommended), or change the format specifier to use "%lf" instead. In either case, the third parameter being passed to sscanf() must be a pointer to dVersion.

Why? lexical_cast is intended exactly for such scenarios. All he needs to do is to include a header file and then to use it like:
double dVersion = lexical_cast<double>("2.5");
Much easier than sscanf and atof, isn't it? Not to mention that it throws in case of error, unlike atof which returns 0
|
|
|
|
|
How is
double dVersion = lexical_cast("2.5");any easier than
double dVersion = atof("2.5");The former requires at least another header file while the latter does not.

For one thing, there is only one lexical_cast and for each type of conversion (string to float, string to int, int to float...) you have a different version of ..to.. function.
But, even more important, atof is simply broken. Consider:
int i = atoi (argv[1]);
if (i == 0)
{
}

The concern was which statement easier to use in a specific context, not which was better adept at error handling or which was more robust.

Hi Everybody,
In my application, i want to erase the particular rectangle area in the client area. I tried using "InvalidateRect()" function. But finally i got the result as erasing of whole screen. Please give some suggestions regarding that.
Actually when we call InvalidateRect function, it invokes the OnPaint() method. In OnPaint() method how can we get the rect region that specified in InvalidateRect() ?
Regards,
Prakash.

 .....well.....
hmmm.....
when u give the InvalidateRect command.....it implies invalidate the whole area.....since
InvalidateRect()----------->meanz....Invalidate(TRUE);
try using.....
Invalidate(FALSE); //THIS ONLY UPDATES THE CHANGES.....NOT THE WHOLE SCREEN.....
hope that helpz.....
happy programmin.....
cheerz.....

i hope to display messageBox in the way of "always on top", that is - HWND_TOPMOST.
do you know how to do that?
if no, is there another easy-to-use dialog similar to MessageBox which can be displayed "always on top"?
thx
