| Simple Text Parser Matthew Bell 19:55:01 |
| | I am looking at developing a simple text parser. Is there an easy way to
format '<b>hello</b> world' and place it in a textbox or label.
I'm looking at implementing hyperlinks and maybe a picture from a text
document like the example above and I might as well add in the normal
b/u/i. Basically I'm looking for speed and a reduction in the size of
the file that needs to be stored as doing this using word documents
would be very sloppy.
Are there any useful controls out there or am I going to have to craft
something myself. And if I'm crafting it myself is there an easy way to
go about it or do I have to start hovering link-labels over textboxes
etc.
Cheers
Matt

| Enumerating Dictionaries Brady Kelly 23:31:48 |
| | I find it a tad irritating that when I want to iterate all the
ColumnDefintion objects in my RecordDefinition, I always have to use '.in
recDef.Columns.Values'.
Is there a nice way I can expose an enumerator over the values property as
my 'Columns' property? Then I have problems adding etc.

| Evaluation of post-increment Brady Kelly 21:49:34 |
| | Suppose I use the following to compare column names in my test columns array
with columns parsed by a parser under test. The parsed columns should be
the same as those used to create the string that is parsed.
RecordDefinition def = parser.ParseLineAsHeader(headerLine);
int i = 0;
foreach (ColumnDefinition col in def.Columns.Values)
{
Assert.AreEqual(testHeader[i], col.ColumnName, "Incorrect
name on column {0}.", i++);
}
Am I correct in assuming that 'i' will always be incremented?

| Guessing field delimiters Brady Kelly 21:28:42 |
| | I'm busy developing a tool to convert my existing base of template based
record layouts to record layouts defined by an XML schema. Maintaining a
record layout definition as one long string full of empty quotes and empty
field double delimiters is looking for trouble. I'm now working on a tool
where the user selects a single line in the existing template, or in an
example file, and my code infers a collection of columns that define the
record layout.
So far, just today, I have come across three different column delimiters,
v.i.z TAB, comma, and something that renders a right angled corner graphics
character. I would like to be able to guess the delimiter, if there is some
sort of pattern I can look for, but it's not easy finding one.
Maybe the best I can do is allow the user to guess, and give a visual
representation of the result of using the guessed delimiter. Another option
is to allow the user to select two field contents and find the non-printable
character in between the two field contents.

| ItemDataBound not Firing on Repeater Brady Kelly 18:04:51 |
| | I have a user control that comprises a Repeater that builds a vertical table
of buttons. In the Page_Load event of the user control I bind an event
handler, but the event never fires. My code is like this:
protected void Page_Load(object sender, EventArgs e)
{
rptPageButtons.ItemDataBound += new
RepeaterItemEventHandler(rptPageButtons_ItemDataBound);
}
void rptPageButtons_ItemDataBound(object sender,
RepeaterItemEventArgs e)
{
throw new Exception("The method or operation is not
implemented.");
}
However, if I use the OnItemDataBound attribute, the event fires. Why could
this be?

| web page and masterpage base classes Mark Aurit 18:03:49 |
| | I use a base page (which inherits from System.Web.UI.Page) behind my
.aspx, and I have a similar one behind my masterpage (inheriting from
System.Web.UI.MasterPage). Im seeing the need by both to use many of
the same functions, but Im assuming I cant use the same for both. Ive
played the cut-and-paste inheritance in the paste, and am not a fan.
Does anyone have any advice for a good strategy to do this? (share the
same functions between different base pages)
Thanks very much

| Custom Paging Brady Kelly 11:37:01 |
| | I'm trying to devise a custom paging control for use with our in house grid
(HTML table with lots of JavaScript). The paging should be alphabetic, so
what I've thought of doing is calculating a page set, with each page
displaying pagelen number of records between 'Aaron - Cook', e.g. where the
records from Aaron to Cook comprise one page. I favour this over just using
a single page button for each letter of the alphabet as the B page may have
more than pagelen records.
This approach will however potentially produce more page buttons than can be
display at once, and it's here I'm looking to enhance the user experience,
to avoid them having to scroll through the page buttons. Any ideas on how I
can present the page buttons to the user in more than just a scrolling list?

| Re: Hide the "X" on a Windows Form Mike Andrews 18:44:15 |
| | I don't believe there is a way to do that unless you want to create your own
owner-drawn form.
You can prevent the form from closing when the x is clicked by using the
Form_Closing event and setting the Cancel property of the CancelEventArgs
argument to true.

GPRS communications  Indy 06:39:55 |
| | I am developing a network of client Kiosk applications that sell virtual products and accept cash as payment. They need to communicate with a central server to find out if the product type is available and communicate with the Kiosk for offer to the customer. Since these client Kiosks will be in remote locations I prefer communication via GPRS modems. The client app is written in VB. How can I design the GPRS communications? |

I have the following declarations:
enum UploadTypes { utRPlus, utRdf, ut3000Extra, utBridge, utDealing
};
UploadTypes UserSelectedUploadType;
Later on I have the following:
UploadTypeCell.Value = UserSelectedUploadType.ToString();
Questions:
Is an enum an object?
Is there a way for me to override the ToString() method?
If not, what would be ways for me to provide a description for each
enumerated value?

| Flat File Generator (OT) Brady Kelly 17:48:51 |
| | Sorry for the OT, but I'm running short of places to ask.
I'm to develop, or integrate, a flat file generator into my integration
application. Using SSIS is proscribed by many client sites running SQL
Server Express, and while I have toyed with the idea of using existing RDL
and report designers to define delimited and fixed width layouts, unless
someone can recommend a tool particularly suited to this, I shall be
developing one.
I have two questions: Is there any way I can use existing ADO.NET
functionality for this, and, what would be a good XML schema to use for the
layout definitions? I see BizTalk has a schema, which I will look at now.
It would be advantageous for me to use a schema, maybe still RDL, that will
allow other tools to consume my file definitions.

| OT: RE: [DOTNET-CLR] Interesting issue Daniel Petersson 14:30:50 |
| | FransB: of course you are right tcp and queueing frameworks are nothing new and your suggestions are perfectly valid within a global scope. Gregs problem scope wasn't global but rather special; don't you agree?
I'm very sorry if I have upset you but i was trying to pass you a note on problem solving; which I thought that this list was all about; suggesting tcp will not solve the problem. I tried to pass this note with a little humor; but hey I'm a SW-engineer and not a comedian and as they say: "I shouldn't quit my day job" ;)
The reason for the note is simple I don't have infinate amounts of time; and I like to help-out on this list and educate my self on this list. Your mail was; as this one also is; off-topic since they wont solve THIS problem.
You previously stated that I shouldn't read your notes if I didn't find them interesting; but that is the problem: I DO find them interesting; (and I also read your blog posts) but when you post of topic you waste my time ...
get my point?
Best Regards,
Daniel

I don't need your freaking permission to post on this list, Daniel so
don't act like you can tell me what to post here and what not. I also now
expect you to bash the people who suggested a queuing framework, because
that's out of the question as well?
So pretty pleaze; with sugar on top; could you please get of your high-tcp- horse and realize that the problem described by Greg can't be solved with tcp. (cleary explained early in the mailings; hence my comment that you need to read the backlog of messages; or atleast state that you haven't) btw: tcp won't solve the problem since we can't change from udp to tcp and therefore it is just a un-informed suggestion (at best) or idotic suggestion (at worst).
Ok, you can't change the transportation protocol, but the solutions
provided by that transportation protocol-that-shall-not-be-named are still the
ones you have to implement as well, as it solves the same problems.
I missed the early mails indeed, so it might look as if I'm stupid, so
for that: sorry.
But that doesn't mean this problem is unique and hasn't been solved
before. It has, many times over. Or do you disagree with that too?

Subject: [DOTNET-WINFORMS] Minimize application - Form and their
Owners...
Hi All.
I have 3 forms:
- MainForm (my top level form) (MF)
- SecondaryForm (SF)
- TertiaryForm (TF)
MF is the Owner of SF.
SF is the Owner of TF.
MF can display SF non-modally, and subsequently SF can display TF
non-modally.
If SF is closed, then TF has no meaning and should be closed, and it
does because TF's Owner is SF. I want to maintain this relationship.
My problem is when I minimize MF. I want both SF and TF to be minimized,
but only SF gets minimized and not TF. I assume this because SF is
directly owned by MF, but TF is directly owned by SF.
How can I make it so that the relationship between SF and TF is
maintained, but when I minimize my MF, all of the forms minimize?
I would have thought that since SF owns TF, that when SF is minimized
(because MF got minimized), it would also minimize those forms that it
owns - but it doesn't!
I hope this makes sence..

| Deriving new Exception Class Brady Kelly 17:04:31 |
| | I needed to set the exception message to a string looked up using an error
code. The error code is passed to my only constructor for my derived
exception. I needed to include a decision on whether the error code was
null or unknown, or a valid key into my message dictionary.
I then found that the only way I could set the Message property was through
the base class constructor, as the property is read only. This meant I had
to implement a static function to determine the error text and use that in
accessing the base constructor. Is there any other way I could have done
this?
public SdkException(int? errorCode): base(GetErrorDesc(errorCode))
{
}
private static string GetErrorDesc(int? errorCode)
{
if ((!errorCode.HasValue) ||
(!sdkErrors.ContainsKey(errorCode.Value)))
{
return "Null or unknown error code.";
}
else
{
return sdkErrors[errorCode.Value];
}
