I am struggling a bit with XML, even as I wade through endless help files and
several books. I thought it would be useful to toss my particular needs to
the group to see what you think is the best approach.
I have a form that is able to read/write from an embedded device with one of
several serial protocols. Through this interchange, I can read or write lots
of different settings in the target. What I want to do now is save the
settings to a file and back again. Here is what the data looks like that I
want to store to a file:
1. Device software info (several strings, "name", "version", "software part
nuber"
2. Configuration data (all binary data, no string) This C structure
contains 8 items, floats, 32-bit signed longs, and 8-bit chars. (Remember,
the target is a "C" guy)
3. Setting data (like #2 above, has lots of values)
4. Digital compensation settings for temperature adjustments (more floats,
5 of them)
5. Linearity compensation settings
....
So, there are lots of settings for each target device. Some of the settings
are determined at design time, some are unique to particular circuit board
configurations, and some are unique to each particular device.
I want to simple be able to write the settings to a file, and read them
back. One day, we may want to hook to a database (in the factory) but I will
likely leave that to the factory engineers to do that. Right now, the entire
app works except for this file reading/writing. Once again, I think I know
what I want to do and it seems simple, but I don't know how to get started.
One final thing: I have created a Schema and am squirting the data to a
file, but I'm not able to figure out how to read it back again and then tell
what I have so I know which text box to stick it into.
Thanks for your patience in reading this.

I run into this situation frequently. I find it very simple and elegant to
use xml serialization:
1. Use the XSD tool to convert your schema into C# classes: http://msdn.microsoft.com/library/de...nitiontool.asp
2. Use the generated classes to write read/write code: http://msdn.microsoft.com/library/de...lizetopic2.asp
Hope this helps.

Hello,
I would like to store multiple dictionaries in a file, if possible one per
line. My code currently produces a new dictionary every iteration and
passes it on to another peace of code. In order to be able to re-run some
experiments at a later date I would like to store every dictionary in the
same file.
I looked at pickel, but that seems to require a whole file for each
dictionary.

I've got an STL class (see below) with two functions to store and
retrieve data - msg structs.
The "Store" function when called will copy the received message
(depending on which message) into the appropriate array. For instance
if I receive a RCVD_MSG1, I'll copy into msg1 . Upon receipt of
the next RCVD_MSG1. I'll copy into msg1 .
The Retrieve function when called should retrieve the latest copy.
ie. msg1 or msg1 .

Hi all,
I have a need for a short program:
Given a drive letter, it would recursively search through all directories,
"generating" each filename that it encounters (need to pass each filename to
a function).
Can't help but think this "utility" already exists but f**ked if I can find
it.

I am used to working in Visual FoxPro and I would like to be able to create

Hi
I would like to ask you a question.
Ian creating app. that download from server directory structure ( whole
tree ) and those data are placed in proper places into my treeview control.
I decided that the most effective way would be : When i connect to the
server once, I download the list and disconnect, instead of connecting every
time i go, to the lower node in my tree hierarhy.
Thus i have a problem - how to store data.

When I write scripts for deleting records in databases, I tend to do it in
this fashion:
- delete link passes ID to a delete.aspx page
- delete.aspx page queries db using that ID to retrieve the file
information
- page displays file information with a 'are you sure you want to delete'
confirmation button.
- upon clicking said button, I delete the record.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
