Hello fellows. I've been wondering, how can I perform a soft-reset (cold-reset) from a CAB installation file?

Regards,

You're wanting to restart the computer? Look at ExitWindowsEx()

Thanks. I'm trying to restart my pocket pc indeed, but not from a common program, but from a cab installation file.

Regards,
Fernando.

Problems with an ActiveX/com control

Hi,

I need to implement an ActiveX control in a simple Dlg based MFC application.
This controls scans the serial port after messages and sends them to my application
( Sniff | :^)

in theory that is)
In a VB application there is no problem to receive the event. But i need it in VC (MFC)
the init of the object seems to work and the messages should be sent (trace line in the
on_fire call) but i don't receive anything in my dlg.

I think that i missed some small init to work with events but i simply can't rememeber
what or wich. Any pointers would be very appriciated.

The following is for MSVC6. If you right click on the ActiveX control on the dialog and select "Events..." a dialog appears which will let you add event handlers.

Very strange ???

I tested it with the calendar control and it works fine. I would guess the control isn't actually firing the event.

Ok
i've done some deep debugging into that altough the Fire_Message is called
there are no connections (connected appz) for this control ????

how is this possible ??? I have attached my project(activeX control) to the
test application (MFC dlg) and I am falling into a breakpoint in the
Fire_Message function, but there is no connection ???

Something wierd is going on.

It all depends on the context (e.g., how did it get there (Lint is assumed)? what code is it near?), I guess.

They want to ignore the Error 470 that the lint might have output for the following code.

You can maybe find out wht PC-Lint Error 470 is, and then that would give you some idea of what potentially squirelly code you are looking at.

Thanks for noticing. I think some people do not beleive there is a difference ... Frown | :(

That is why I kept it as the byline for quite awhile now.

I think it's related to LINT[^] which is a static C/C++ Analyser, to check for programming errors and other stuff like that.

might be to suppress error 740 when running lint on that file ( or next few lines ).

With Win32, use OutputDebugString(). With MFC, use TRACE().

Can't you use OutputDebugStr()? Try the TRACE macro also.

Why is common sense not common?

I have given the following arguments to a program.

-i:Test_Data1.txt -i:Test_Data2.txt -o:Test_Data_Diff.txt
-c:"TOW:Udop:dN,0.2:vU,0.0005:L1P Sats:Slow nSat" -r:TOW -a:alertfile.txt

-i:Test_Data1.txt ....... This is the filename of first file
-i:Test_Data2.txt ....... This is the filename of Second file

My goal is to do the differences between both the files. I have 39 columns in both the files. I need to get the differences for only the columns i need.
so, i am giving the column names for which i want the differences as arguments i.e the following
-c:"Time:Salary:limit,0.2:age,25:Status:hours".

Suppose i declare two variables int argc, char *argv[]

i know that i would have "-" in argv[i][0], i/i/o/c/r/a in argv[i][1] etc

I want to take out 0.2 or 25 from this argument and store it in another varable. How can i do it?
c:"Time:Salary:limit,0.2:age,25:Status:hours".

the argument can also be like this.
c:"Time,0:Salary:limit:age,25:Status,1:hours".

I want to pick up the number which comes after the comma and store it in another variable. How is this possible?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
