Application invokes Read(Char[], Int. Int) method for a serial port to read
a single port. Framework appears to first do a GetCommStatus() call to the
serial port driver to see if data is available. If data is present, then a
single byte Read call is made to the serial driver and everything is fine.

However, if GetCommStatus() returns with no data being available, then the
Framework makes a multiple byte (observed to mostly be for 2 bytes, but
sometimes for 3) Read call to the serial driver which eventually results in
a request timeout since the device connected to the serial port only sends a
single byte (as the application was expecting).

Observed behavior is that between the GetCommStatus() and Read call to the
serial driver, the desired byte arrives so that when the Read request comes
down to the driver it is immediately moved into the return buffer for the
request, but the request gets pended until it times out because the
Framework issued the request for multiple bytes instead of the single byte
which the application requested.

Why does the Framework change the Read request sent to the serial driver
from being the single byte request made by the application into a multiple
byte one when the GetCommStatus() call returns with a data count of zero (0)
for the incoming data?

Is it possible to display context-sensitive help from a .chm or .hlp
file on a .NET win forms application?

We want to associate UI controls with placeholders from the chm or hlp
file so that if a user invokes the "help" button and then clicks on a
control, the help specific to the control is displayed in a floating
rectangle.

Does .NET provide built-in support for this?
HelpProvider opens the CHM file. Instead I want to show the help
associated with the control like a tooltip. The help text will not be
hardcode in
the program but will come from an existing CHM/HLP file.
I should be able to do something like
ContextHelp.AddHelp(txtBox1,4000) where 4000 is the ID of some help
text present in the CHM or HLP file.

Thanks,
Yash

Is there a way (preferably an easy one!) to detect the supported baud rates
of a given serial port???

Some coms devices I'm using work fine at 115200, others need to be at
460800, and I need to detect the available baud rates to see whcih one I
have in place.

If I select the different devices in Hypertemrinal, it will list the bauds
available, so surely I can pick them out from somewhere...?

VS2008
I am displaying various reports using the ReportViewer control in a Windows
Forms application.
The user can choose from a number of different reports by selecting an rdlc
file to load into the ReportViewer.
For some reports I need some additional information to be available to my
application.
At the moment this data simply consists of a list of named items, the value
of each item is an integer (or an enum).
I could create my own new file format which included everything in the rdlc
file and my extra data, but I wondered if there might be a way to actually
store this data within the rdlc file.
I can easily extract data from an rdlc file in my code, as it is an XML
file, but I would like a nice simple way to allow my colleagues who will be
designing the individual reports to add this data.
I was wondering whether this could be done using a custom report item?
People could then add this information in the report designer.
I have started reading about this, but all the articles refer to SSRS which
I am not using. Before I spend too much time learning all this stuff can
someone please confirm that I can still user CRIs with the ReportViewer ...

Hi,

Urgently require help on this.

I've deployed an application developed using VS2008, complied in .NET
Framework 2.0, into a web server whose applications were developed with
VS2003. I've added a virtual directory via IIS

After my deployment, older applications that used .NET Crystal Report
component developed with VS2003 were affected. Is there any advise on what
can i do to the web server?

Web server is already with .NET Framework 2.0.

Thanks!!

Does NET 3.5 run on Win2K Server?

Hi All,

I was giving a task to find a flash type module that will be closed to
functionality to the flash one used on http://www.zinio.com/gncoffer?issn=CDSPVGB&of=ZH01&ns=usa
(click on the cover page to activate the flash). Now, I understand
that it is custom written for that application but I was hoping to
find somewhat similar along those lines, I spent three days looking
and searching, so far nothing.

If any of you know, heard or have seen something similar, please share
with me and the community.

THANK YOU IN ADVANCE.

I am inputting data into a form that was created by an associate. Example:
Name (tab)street (tab) city(tab) etc. however it does not tab to the next
box. How can I change it to make it tab over? This person told me they
forgot this box and put it in at the end. I am in form design but can't
figure out how to correct it. Thank you.
