hi all,

I am building a system tray like utlity for a mfc dialog based application( infact property sheet based application). just like Date/Time Property sheet application. in system tray.

I have done following.

1. Initialize the NOTIFYICONDATA structure m_nidIconData
2. Declare and defined a called back function using a user defined message.
3. Calling Shell_NotifyIcon(NIM_ADD,&m_nidIconData)in InitDialog of PropertySheet class.
4. handing msg in call back function such as WM_MOUSEMOVE,WM_LBUTTONDOWN etc.
5. Calling Shell_NotifyIcon(NIM_DELETE,&m_nidIconData) in d'ctor of PropertySheet class.

When ever i moved my mouse message the tray icon gets disappeard.
Can someone throw light on the problem?

Thanks in Advance

No "Press any key to continue"

Suddenly all the console applications written using the wizard in Visual C++ 6.0 no longer finish with "Press any key to continue" so I have to use my own few lines of code to see the results.

What have I done

From where are you running the console applications?

I have been running them from inside the Visual C++ development environment using the F5 key, however running the exec file directly has the same result.

Unfortunately I do not have any "old" console applications lying around that I am certain are working (eg that the file they were reading is still there etc )but the ones I have tried all seem to start up and then immediately close again with no message.

Could it be something that has changed in the operating system which is Windows XP? I believe that the service pack 2 updates may have been made since I last used a console application.

It used to be that when you ran a console application from an already-open console window, the console window would remain open after the application exits. When you ran a console application from within the IDE, the console window would prompt you then close.

To be honest I cannot remember what happens is you run outside IDE but something has definitely changed as an "Hello World" program run from within IDE runs and immediately closes. So either I have inadvertently set some switch within IDE or there has been a change in the operating system.

add this in your code to pause temporarily your running program :

add this header :

<font color=#0000FF>#include</font> <conio.h>

and this where you want to stop :

getch();

How are you calling ShellExecute()?

Hi David,
Thanks for showing interest.
I am invoking this function when a dialog-print button gets clicked.
ShellExecute("Print", "ABC.htm", NULL..);
I get the html page printed , but before printing, its opening up the print dialog. Do you know how to suppress!

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.

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)?

sscanf() vs atof() !?

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>//...</font>
sscanf(strVersion, <font color=#808080>"%f"</font>, &dVersion);  <font color=#008000>// dVersion is about 3.846..........E-314</font>
 
dVersion = atof(strVersion);         <font color=#008000>//Works fine</font>

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
