| Why properties cannot be used as ref or out arguments Dean Cleaver 10:23:37 |

passing, but I can't figure out why they can't be used as out arguments?
Any thoughts?

| Funny Comparison with Float Brady Kelly 06:56:09 |
| | My colleague has just noticed a funny in comparing a float to a literal
value. Where 'version' is a 'float', the expression "version == 1.1"
evaluates to false, where the comparison "version == 1.1F" does. Last
week's thread on floating point maths prompted me to raise the issue here to
find out from the experts just what happens here.

What are the main benefits of using a Web App project over a Website

Web App Project: You have to jump through hoops to use edit and continue
with a Web App where in a website it just works. I've figured this out
with the help of ScottGu. Thanks!

Website Project: how do you set up the project to use a bin directory
and compile and place the .dll within?

| MSMQ - Cannot find a formatter capable of reading this message Silky 01:25:29 |
| | Hi guys,
I've just received this error message in my app, after using MSMQ's
for quite some time in it. The error happened when moving the system
live [kind of].
The exact stack-trace:
System.InvalidOperationException: Cannot find a formatter capable of
reading this message.
at System.Messaging.Message.get_Body()
at [place where I call .Receive()]
So the point is; this works on my dev machine, and has previously
worked on the live machine, but only just started going wrong. I'm
thinking maybe it's a service pack, or perhaps the name of my queue?
At first I had a name in the form of "aaa_bbb - mmm" but I thought
perhaps it didn't like that (even though it created them fine). Now
they are simple of the form "aaa_bbb_mmm".
Anyway; just wondering if someone can shed some light. Searching
hasn't lead me anywhere yet.

Emne: Re: [DOTNET-WINFORMS] SerialPort.WriteTimout
Thanks, Don. I have a very small test c# (2.0) app that opens a serial
port, sets the baud rate and a few other items, and then writes a stream of
50 chars. Doesn't seem to present a problem. I have a much larger, more
complicated c# app that also writes to a serial port with similar port
settings and less characters and I keep getting a write timeout error. So
it doesn't seem to be the hardware. I am looking for other places I might
have screwed up (and yes, I do know the port is open!  .

It's not always just the length of the data and the baud rate. I've seen
write timeouts happen when using virtual serial port controls even though
given the baud rate and the length of the data there was ample time to
complete the operation. The most recent drivers for the siLabs 210x USB to
Serial chips seem to be especially slow. With a write timeout of 400ms I was
sometimes unable to write 2 characters to my device at 38400 baud.
If the write operation isn't completed during the timeout period a
timeoutexception will be thrown.

I have been searching for info on what actually will cause a WriteTimeout

articles that talk about a Write operation not being able to complete in the
time allotted. However, besides having a series of bytes to be written that
when taking into the account the baud rate cannot complete in the allotted
time, I can't think of another reason for this error to occur - nor can I
find reference to when it will occur.
Any ideas or places you could point me, please?

| Simple data binding in ASP.NET chris Burgess 20:01:33 |
| | I have a 'Person' object with 2 properties (name, age).
I want to bind these properties to textboxes on an ASP.NET page
(NameTB, AgeTB). Is there a way to do this that is similar to the
simple data binding methods used in a Winform (using the Binding
object)?
So far, I've only been able to setup INotifyPropertyChanged, and
handle this through event calls.
Thanks!

| Web Service returning untyped DataSets only; how to get typed data access? Per Bolmstedt 15:25:04 |
| | (I posted this to a newsgroup[1] this morning, but since I hold the
discuss.develop.com lists in high regard, I thought I'd try here as well.
I've search the list archives and found similar topics come up a few times,
but nothing that helped me.)
I am consuming an ASP.NET Web Service which returns only DataSets for
all operations. The format/schema of the data returned by each method
is known and doesn't change. Untyped DataSets are inelegant to use on
the client when the data format is known, so I want typed data access
to each response type. Using a typed DataSet would be fine, but
anything that programmatically lets me access data is fine.
What is the "Visual Studio" (2005, 2008, doesn't matter) solution to
this? I have attempted to create typed DataSets from the Web Service
using every VS method I could think of, but I haven't gotten it to
work. Things I've tried include
1. xsd.exe /d using actual response XML: the generated .xsd file is
not usable as a typed DataSet as far as I can see.
2. xsd.exe /d using an XSD generated with WriteXmlSchema on the
DataSet returned by the Web Method: same as above.
3. "Create schema" in Visual Studio using actual response XML: I've
found no way to go from here to a typed DataSet.
My current solution is very old-school and relies on XmlSerializer to
deserialize the DataSet/DiffGram XML embedded in the DataSet returned
by the Web Method. This seems to me like a very un-Visual Studio
approach. The only working alternative I have so far is manually
creating typed DataSets, using the Visual Studio designer, to match
the response DataSets. Obviously, this too feels like a suboptimal
approach.
There are numerous references to "Generate DataSet" in the
documentation, but that command is always disabled, regardless of how
I create an XML schema. I'm assuming strict requirements are made on
the XML schema for this to work, but I can't find any information in
the documentation. Maybe it doesn't work the way I imagine it does.
I've also found many references to the drawbacks of using DataSets as
response types in Web Services, but there's nothing I can do about
that.
Any thoughts? All I want is early-bound, typed, programmatic access to
data in the DataSet.
For example, the SOAP response can look like this:
<DataSet>
<xs:schema id="NewDataSet">
(Actual schema here.)
</xs:schema>
<diffgr:diffgram>
<NewDataSet>
<MyItem diffgr:id="MyItem1" msdata:rowOrder="0">
<MyProperty>1</MyProperty>
</MyItem>
</NewDataSet>
</diffgr:diffgram>
</DataSet>
(Currently, I am invoking all Web Methods, running the included schemas
through xsd.exe /c, and ultimately deserializing to the generated classes on
the client.)

| Update page from client JaveScript Paul ten Brink 10:57:34 |
| | Hi,
Asynchronous callbacks are great for responsiveness. But sometimes in such
a callback I find that the entire Page has to be refreshed, just like in a
normal postback.
Normally I would use Response.Redirect() or Server.Transfer() but both are
not allowed in an asynchronous callback...
So I'm stuck with updating the Page from client JavaScript, but the only
way I know how to do this (window.location.reload) results in a dialog box
"Are you sure you want..." and the Page does not really update.
Is there another way to issue a normal postback of a Page in client
JavaScript?
Thanks for your time and help.

| Structures not behaving as value types Richard Kucia 22:05:09 |
| | I have a VB.Net declaration of a structure strFieldMask. The intended
purpose is to store a bunch of bits, like a bit vector. The structure also
has operator declarations for =, <>, And, Or, Not and <<, plus some other
methods for bit manipulation.
The problem is that variables of type strFieldMask seem to behave as
though there was a singleton strFieldMask and all instances shared it.
Consider this:
Dim Mask1 as strFieldMask
Dim Mask2 as strFieldMask
Mask1 = (formula for computing the next unused mask value)
Debug.WriteLine(Mask1.ToString))
Mask2 = (same formula)
Debug.WriteLine(Mask1.ToString)) ' Yes, Mask1, not Mask2
The result from the first WriteLine might be "0x10" and the result from
the second WriteLine might be "0x20".
I've successfully used structures before, but this is the first time I've
tried overloading the operators. Has that caused the behavior I'm seeing?
Thanks.

| How to determine read/write status of a property chris Burgess 19:17:54 |

(other than trying to write to it)?
e.g.
If:
Public ReadOnly Property Name() As String

then I want the textbox on the form to be read only.
If:
Private _name As String
Public Property Name() As String
Get
Return _name
End Get
Set(ByVal value As String)
_name = value
End Set
End Property
then I want the textbox to be read/write.

| Merge MDI child toolstrip button(s) into parent toolstrip Holly Styles 22:40:27 |
| | Hi All,
I have the need to append/replace toolbar buttons in the MDI parent window
of my application. For example my child form has a toolstrip object, on that
toolstrip is a save icon. When the child form is shown/active I need that
save icon to be appended to the parent's main toolstrip, or added as a
toolstrip into a main ToolStripPane in the parent. I have been researching
this for a couple of days and there are many references to using
ToolStripManager and it's Merge and Revert methods etc. during Child
Activated event handling. I have read this technique can lead to hideous
screen flicker however.
Can anyone recommend a best practice for this type of MDI Application
scenario? Or where the best tutes can be found? I am drawing a bit of a
blank with this one. I'm fairly new to Windows Forms as most of my
experience is ASP.NET so I havn't touched Menu's and Toolbars since my VB6 days.
Any pointers much appreciated.
Thanks and regards.
-Holly.

| Button image is lost (???) Gyorgy Bozoki 08:25:11 |
| | Hi all,
I have a DLL project in C# that has a dialog with a few controls, one of
which is a button. The dialog has its own custom icon (stored in the
dialog's resx file.) This shows up fine.
I'm trying to assign a gif file to the Image property of the button using
the form designer - select the Image property, click the ellipsis (...)
button, select Local resources in the "Select Resource" dialog and then
click the Import... button to select the image file. When I hit Ok on the
dialog, the selected image appears on the button and when I save it, the
image gets saved into the resx file. Yet, when I close and reopen the dialog
in the designer, the image is gone. (It's still in the resx file.)
Am I missing something here or is this a bug?
Thanks a lot,
Gyorgy Bozoki

| Funny loop with post-increment. Brady Kelly 19:56:35 |
| | Why does this loop not exit? On the first iteration, one would expect i ==
0, and that 0 to be assigned to i, and then i incremented. Then, on the
second iteration, i should be 1 before the assignment operation, as well as
after the assignment operation, but i should be two after the
post-increment, before the next assignment.
int i = 0;

| [OT] ? FontFamily and PostScript font names... Gary Harpin 15:46:33 |
| | Hello All,
I am working on some code to process an SVG file. I have hit a problem with some of the test files that I am using (the problem files seem to be ones generated from Adobe illustrator). From what I have found so far It would seem that Illustrator saves the font information using a Postscript Font name (see table below). The problem I am having is that I can not find out how to get from the postscript font name to a font name that I can use. Can anyone point me in the right direction?
Font used in Illustrator Resulting font attribute in SVG file
======================== ====================================
Arial Black (Regular) font-family="'Arial-Black'"
Arial MT (Bold) font-family="'Arial-BoldMT'"
Square721 BT (Bold) font-family="'Square721BT-Bold'"
Swiss921 BT (Regular) font-family="'Swiss921BT-RegularA'"

| Problem with Parent Child Data Binding Brady Kelly 13:37:11 |
| | I have a parent child relationship, on DocumentID, between an invoice and
invoice lines. A form displays invoice fields and has a grid for invoice
lines. The grids BindingSource points to the Invoice Binding Source, and
it's DataMember to the relation, so I think this is correct.
Now, if I leave the relation type to Only Relation, the DocumentID in my new
Invoice is -1, and the DocumentID in my Invoice Lines grid is also -1, but
the Line record remains -1 after being written to the database. So, I think
maybe I should make the relation a constrain as well and add a cascade
update, but then I get an error that -1 doesn't exist in the parent table,
even though the Invoice datatable DocumentID is -1.

| StringBuilder Extension: IsQuotedBy Brady Kelly 12:28:32 |

and came up with the following method to see if a StringBuilder, that I use
for each of a collection of string fields, is surrounded by a certain
string, e.g. double quotes. I was just wondering if this is an efficiant
way of doing it:
public static bool IsQuotedBy(this StringBuilder sb, string
quoteString)
{
// Check if the first characters match the quote string.
for (int i = 0; i < quoteString.Length; i++)
{
if (sb[i] != quoteString[i])
{
return false;
}
}
// Check if the last characters match the quote string.
for (int i = sb.Length - quoteString.Length; i < sb.Length; i++

int qsIndex = 0;
if (sb[i] != quoteString[qsIndex++])

| Calling Webservice Thru an Interface Mark Potter 13:57:12 |
| | Hello,
I have a web service that implements an interface as follows:
[XmlInclude(typeof(AdvancedDTO))]
public class AdvancedWebService : System.Web.Services.WebService,
IAdvanced
{
#region IAdvanced Members
[WebMethod]
public AdvancedInterface.AdvancedDTO makeMessage
(AdvancedInterface.AdvancedDTO aDTO)
{
BusAdvanced ba = new BusAdvanced();
return ba.makeMessage(aDTO);
}
[WebMethod]
public AdvancedInterface.AdvancedDTO[] listMessage
(AdvancedInterface.AdvancedDTO aDTO)
{
BusAdvanced ba = new BusAdvanced();
return ba.listMessage(aDTO);
}
#endregion
}
On the client side when I register the web serivce the proxy generated
does not have the Interface implemented. I have to go in a touch up the
Reference.cs to implement the Interface.
public partial class AdvancedWebService :
System.Web.Services.Protocols.SoapHttpClientProtocol,
AdvancedInterface.IAdvanced {
Are there any tools out there that will generate the web service proxy
with the Interface.
Thanks in advance.
