I am using VC++ MFC control.I am having a form which contains a combobox,a listbox and button..now I hv few text files say for example abc.txt,cdf.txt and so on..Now if I select a particular name say abc from combobox all the parameter names which is in that file "abc.txt" will automaticaly get displayed in the listbox.Each file has a parameter number ,name and value,so while displaying the parameter names I have used indexes.
So the format stored in the text file is as follows:
Format: Example:
index no 0
parameter no1 4
parameter name1 fdf
paramter value1 A3434
index no 1
parameter no2 7
parameter name2 eter
paramter value2 B3565
.. ..
.. ..
and so on..
These values are copied into these text files from a particular text file
which contains parameter no,paramter name and parameter value without index numnber.I hv used it for displaying names on the listbox.
So my doubt is:
How to display the list of parameter names of each text file whenever the file is selected using combobox on the list box without using the index numbers.I dont want to use it since it takes extra space in the file.Is there anyway to do this?Please suggest me and help...

i have a cwnd object, and i have another one inside a cformview
i think the one inside the cformview is not capturing the notifications
NM_CLICK, for example, pretranslatemessage still gets them, but onnotify doesnt
the one outside the cformview works fine
any suggestions? thanks

Hi all,
I am currently writing a program that will be running on an XP-embedded machine that will act as a watchdog and launcher of another application. Naturally, since this needs to be persistent on the machine, it makes since to write it as a windows service. However, I'm not sure what benefits this will have over a standard application because I have not had a great deal of experience writing services. For one, these machines will never be touched by end-users so an application running in the taskbar would not have the problem of an accidental closure or user error. Two, this program may require relatively constant communication with the application it opens and know if it dies so it can report back to a central server, as well as status update to said server.
So I guess my overall question is are there any caveats to writing this as a windows service? Is there any performance gain or loss when it comes to messaging between the applications? Any opinions and thought are greatly appreciated.
Thanks,
Dustin

I work on XPe and we do everything quite deliberately as applications, not services. The only real benefit a service has is the built in ability to be restarted by the service manager. Our solution is make sure our "services" don't crash. (Some of our services can't really be restarted anyway
On the negative side, services are annoying to debug (when problems happen when in service mode) and maintain in an XPe environment. In our case, we push down updates, the machine reboots and the updates are xcopy installed. Can't do this with services.

Thanks Joe, that is very informative and helpful. We actually just had another meeting about it and I believe we are turning away from the service idea.
Thanks,

Hi Still i am not able to achive it.
I cannot use your dll,can you please tell me any other way i can achieve this requirement ?

I believe Excel files are locked for writing, so perhaps you could open the file requesting exclusive access.

There's this utility: http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx Mark used to publish the source and it may still be available somewhere. You could ask on the forums from the sysinternals subsite.

I think what Rajesh[^] said is a right choice for you.

You can check the Running object table for an already running instance of Excel. Get the properties of the document object to check whether it is your excel file.
You may get the VC++ code and details from this MSDN KB Article[^]

can you help with some othe option ?

Did you try the option which I mentioned in my previous post ?
Using GetActiveObject()[^] ??  to check whether excel is already running or not.

What I mentioned in last post[^] was VC++. Please click on this link to see the same VC++ code for checking whether excel is running or not.

So did you even bother trying to open it?

You seem to be contradicting yourself. "Multiply" and "Divide" are different, as are "Fahrenheit" and "Celsius."

As you can see the button have 2 hover states
What I intent to do
if the user clicked on the left half the button perform division or Fahrenheit to Celsius if the user clicked on the right half the button perform multiplication or Celcius to Fahrenheit
The button perform 2 operations depending which half you click

Which is exactly what the article I pointed you to does, although it has 8 "sides."
