System.Xml - Controlling linebreak/indentation on child/inline ele
I'm going insane fighting against the xml reader/writer. I have xml that
should look like this:
<source><g>varname</g> some text <g>varname</g> <g>varname></source>
This is a simplified version, but the point is that all spaces in the
<source> element are significant. My problem is two-fold. First, the writer
is determined to format this like so:
<source>
<g>varname</g> some text <g>varname</g> <g>varname></source>
If I use the xml:space="preserve" attribute, I get the linebreak and
indentation spaces. If I don't, I lose the space between </g> and <g>. The
problem comes in when there might actually be significant spaces before the
first <g> element. Distinguishing between significant spaces and the
indentation spaces can't seem to be done. So the solution is probably to have
the writer not put the <g> elements on a seperate line. But I can't figure
out how to do this. Or maybe there's another way?
This is killing me. Please help. Tag: Using Webclients through proxy servers. Tag: 88410
Calling a service from a windows client
Hi
I'll try and keep this short! When calling a web service async. I can use
the Beginxxx method on the generated proxy. But if me 'service' was not a web
service but something else, is it better to create a new Thread for the call
or use the threadpool; baring in mind that the service call could take a
little while (between 1 and 10 seconds, depends on the amount of data
returned!)

Avoiding deadlock caused by Invoke
I?ll try to explain my situation as clearly as possible? J
I have a UI form that fires a worker thread. The worker thread regularly
updates the UI via an Invoke (naturally). So far so good. The UI form also
has a button that can abort the thread. What I?m trying to achieve is for
the UI to say that the thread has been aborted once it has indeed been
aborted. Here?s my problem:
The user hits the Abort button which does an Abort() on the thread (after
interrupting a waitsleepjoin) and, as per the MSDN documentation then does a
join() to wait for the worker thread to finish (the documentation says that
I *must* join). The worker thread captures the abort signal and attempts to
update the UI via an Invoke. Of course, the main UI thread is now already
joined to the worker thread, so the invoked method called by the worker
thread sits in the UI thread queue and is unable to proceed because the UI
is waiting for the worker thread to abort. Result à deadlock.
I?m sure that there?s a ?standard? way to resolve this presumably common
scenario, but I just can?t seem to track it down. Any ideas?
TIA

Slow AD query
Hi there,
I'm creating a little application that between other things will get the
logged user information and will do a AD query to get his distinguishedName
attribute but that query is taking too long (about 8 seconds).
The code for the C# method is as follow:
string[] propToLoad = new string[] { "distinguishedName" };
string filter = "(&(objectCategory=user)(sAMAccountName=" + accountName +
"))";
DirectorySearcher searcher = new DirectorySearcher( filter, propToLoad );
SearchResult sr = searcher.FindOne();
if ( sr != null )
{
return sr.GetDirectoryEntry().Properties[ "distinguishedName"
].Value.ToString();
}
return null;
where accountName is the logged user account name.
Any idea why that's happening?
Am I missing some initialization?

Interop problems using VFP 6.0 and Framework 2.0 beta
Hi All,
There is a incompatibility between VFP 6 and Dotnet 2.0.
we have a VFP class called message.dll, initially this was compiled in
VFP 6.0
we did the folowing
1) use regsvr32 "message.dll" and register on client machine
2) used tlbimp message.tlb /out:messageDotnet.dll to convrt it to a
dotnet DLL
the above two steps gave no problems
We then referenced the messageDotnet.dll class from dotnet 2.0 and
whenever we executed the code it returned the following error
"user-interface operation not allowed at this time".
the funny thing was that when we tried to reference the original VFP
6.0 dll i.e "message.dll" from vb 6.0 it didnt throw any error.
Now on a hunch we RE-compiled the VFP message.dll using VFP 7.0 and
re-added it to the Dotnet solution, after recompiling as outlined in
the steps 1 and 2; and
Viola there was no problem and all worked fine
What is this weird behaviour about, please enlighten us !!!!

Code runs with breakpoint, but without bPoint gives StackOverflowE
Okay, I have this app. On load it runs an initialization routine on an
unmanaged .dll. The code has a button. The handler calls a function
'FillCameras'. If I put a breakpoint at that line (Call FillCameras) the code
runs fine, even if I don't walk through the code after that. It seems to just
need to pause. I can then remove the breakpoint and click the button as much
as possible, and it fires as expected.
If I do not have a breakpoint at that line, or any other line, and let the
button fire on it's own, I get: An unhandled exception of type

Visual Studio Functionality
We're having a bit of a quandary at my office and this seems to be the
perfect place to get the answer and perhaps some clarification. Currently,
the "official" architecture for my organization is J2EE. It is my
understanding that the .NET framework serves essentially the same purpose and
that it exists as part of the operating system in Windows. In the past there
have been a number of applications developed in either MS Access or Visual
Basic. Many of these may never be converted to Java and it certainly won't
happen anytime soon. As a result, some people are asking for newer versions
of Visual Basic (i.e. .NET) in order to maintain and improve these existing
applications. Is it possible to use Visual Studio and only develop
"straight" VB code that does not use the framework (this has been
specifically prohibited by upper management)? Do all versions of Visual
Studio give you access to the framework or only the enterprise versions? If
all versions give you access is it possible to determine if/when you are
using the framework? I would really appreciate some guidance from those of
you who are very familiar with this product. Thanks in advance. Tag: Using Webclients through proxy servers. Tag: 88354

Code generation for array of components
Hello all,
I am trying to create a custom component which contains an array of another
custom component. A property is added to wrap the array - this allows .NET's
built-in property editor to provide a comfortable means to populate and edit
the array. The problem I have run into is that after all this is done, the
array itself is never generated into code and all the created objects simply
spill onto the form as well - which can be a problem because of the size of
the array I would like to create. I would prefer not writing a custom editor
and code generator because I think .NET should have all I need, I just need
to figure out how to control it.
Hopefully this example might clarify what I am trying to do. Assume I create
a new component, and add the following code to it:
**************************
private System.Timers.Timer[] tarray=null;
public System.Timers.Timer[] TArray
{
get
{
return tarray;
}
set
{
tarray=value;
}
}
***********************
Now, after I compile the class and add it to the toolbar and drop an
instance of the component onto my main form, it has a TArray property. I can
click on this property's ellipsis button ("...") and populate this property
with timer objects. As I do this, 2 problems occur:
1 - when I'm done and click OK, the array is never created in code - it
remains null regardless of any editing that occurs - so the next time I edit
my object's TArray it is empty again
2 - the timer objects are created, but apart from the array and they appear
separately in the form editor
In this example, I would still like to be able to create timer objects
outside the TArray property and have them appear on the form - only timer
objects which are created inside the array should not appear separately.
Any tips on how to generate the desired behavior (array's code generation
and only the container object in form editor) are greatly appreciated!
Thank you,

Monitor class not working as specified
Hi!
I have trouble with the Monitor class.
I did some troubleshooting and finally figured out the
problem. The thing is, the Monitor class simple does not work
as specified.
Better said, if used by the framework through lock( obj ) statements
it works fine, however if used through Monitor.Enter( obj ) and
Monitor.Exit( obj), deadlocks can occur.
Here is a simple example that shows this behavior. If the example
is run as specified everything is fine. If the lock statements are
commented, and Enter & Exit statements uncommented deadlock occurs.
Why this happens? .NET framework help specifies that this should be
the same. I found in the help, that Monitor maintains Waiting and
Ready
queues of threads for each object, but I haven't found the clear
explanation
of the meanings of this queues.
Any sugestions?

Problem converting OLE Metafile to Bitmap
I'm having issues converting a metafile into a bitmap. The metafile is
the presentation data stripped from an OLE object. The OLE headers
have been stripped off and what appears to be the MetafilePict header
has also been stripped off.
The metafilepict header, though, contains all of the sizing information
(which I need) in order to keep the resultant bitmap the same size as
the original presentation metafile.
When I try to force the metafile into the given size, the resultant
bitmap always looks as if the text within it has been scaled down (and
so the bitmap text looks nothing like the original presentation of the
OLE object.) This only seems to affect the text. More complex objects
(with graphs, etc), seem to translate OK.
I've tried numerous different methods for converting the files , none
of which seem to work. From basic ideas like:
Image i = Image.FromStream(fs);
Bitmap b = new Bitmap(i, new Size(pictInfo.xExt, pictInfo.yExt));
// gives correct size, but text is sized incorrectly
To more complex ones using hardware device contexts, sizing rectangles
for the metafile, etc. Nothing seems to make the text size come out
right (or in the case of the hardware device context -- not at all.
I'm sure I've got issues there.)
Is there an easier way to:
1) maintain the correct text size in the metafile to bitmap conversion?
2) dump the metafile to some other graphic?
-or- the point of this entire exercise
3) dump the presentation data of an OLE object (as it appears in the
application) to a file that can be viewed (jpeg, bitmap, tiff)?
Any ideas/code hints would be greatly appreciated.

Compiled Regex in 1.1 & 2.0
Hi,
I had a problem with a rather complex regex expression that didn't return
the same results in 1.1 and 2.0. I first thought that I could make a
utility assambly that referenced the 1.1 version of mscorlib and the use
that from the 2.0 application. But that didn't work so I drew the
conclusion that the problem was the runtime. That was wrong. I've compiled
the regular expression in 1.1 into a physical assembly using
Regex.CompileToAssembly and it works fine when referenced from the 2.0
application. The problem seems to be the actual parsing of the regular
expression in 2.0.
I don't know what goes wrong, but I now have a working workaround so I'll
let it drop. Now I'm just wondering if somebody at Microsoft would like to
pick it up to ferret out the possible cause.
Pattern (IgnorePatternWhitespace):
(?<list>
\[
(?>
([^[]|[]])+
|
\[ (?<DEPTH>)
|
\] (?<-DEPTH>)
)*
(?(DEPTH)(?!))
\]
)
|
(?<structure>
\w*\(
(?>
[^()]+
|
\( (?<DEPTH>)
|
\) (?<-DEPTH>)
)*
(?(DEPTH)(?!))
\)
)
|
('(?<quot>
[\w]*
)')
|
(?<variable>
[A-ZÅÄÖ]\w*
)
|
(?<value>
[a-zåäö]\w*
)
Input:
value,Var,[L1,L2,[L3,L4]],'Text',p(a,b)
Desired result (one row per match in Matches):
"value" in capture group 'value'
"Var" in capture group 'variable'
"[L1,L2,[L3,L4]]" in capture group 'list'
"'Text'" in capture group 'quot'
"p(a,b)" in capture group 'structure'

C# and VB.NET
Why does C# seem to get more "play" in the .NET world? Don't both of these
languages compile to the same IL language. I know both languages has its own
little features; but when I look at job postings I get concerned when I see
verbage like "C# is a Must". I program mostly in VB.NET; but I don't think
it will take me that long to get use to the c# style. Programming in .NET
language shouldn't matter right? Anyone else would like to comment? Tag: Using Webclients through proxy servers. Tag: 88306
XmlTextWriter and Extended ASCII
I am using XmlTextWriter to extract data into the database. The problem
is that I cannot get XmlTextWriter to support the extended ASCII.
Everytime it runs across an extended ASCII character, the XmlTextWriter
will translate it into '?'.
Is there a way to get around this or am I doing something wrong?
Thank you Tag: Using Webclients through proxy servers. Tag: 88304

Unsafe code: Converting "byte *" to "[] byte"
I've converted "[] byte" to "byte *" at times, using 'unsafe' and
fixed { .... }, but the reverse does not seem to work.
In this case, a C++ DLL returns a byte * and a length. What is the best
way to convert these to straight C#-compatible straight "[] byte" arrays?
PS: The C++ DLL is actually managed and I have access to the source.
Perhaps there is a simpler syntax for doing the conversion there, and
returning a C# compatible array rather than a pointer? Tag: Using Webclients through proxy servers. Tag: 88301
There are no context policies.
Could somebody explain this error for me? :
There are no context policies.
: Unhandled exception: System.Threading.ThreadAbortException: Thread was
being aborted.
at System.Threading.Thread.Sleep(Int32 millisecondsTimeout)
at Plugin.Chat.Run()
DotNet app use some C++ library thru wrapper and sometimes when the c++ app
throws an exeption (handled) i got errors like above. What is interesting
all threads worked in dotnet application throws exceptions like this.

Dataset.Merge Concurency Violation
I am using SqlClient and OleDbClient classes to copy data from an msaccess db
to a sql server db. These two dbs have the same structure.I want the changes
that have occured in the records in the msaccess db to be updated to the sql
server db.
I am loading data from a table in msaccess into a dataset(dsSrc) and loading
the same table from SQl Server into another dataset(dsDest). then i am
calling the dsDest.merge method to merge the changes in the two datasets.
Upon updatation of dsDest i get the following error from the sql server db
"Concurrency violation: the UpdateCommand affected 0 records"
I am the only user on the 2 databases.
I checked the contents of the dsDest before and after the merge.

information please ask at this thread.

app.comfogv Localization
Hi all,
is there any way to tell the program to execute under any given
CultureInfo setting, using the app.config file? Similar to the asp.net
web.config setting <globalization> tag, but for WIndows Forms????
I know how to set the CUltureInfo of the current thread, but have no
idea on how to set it at app.config level
Any ideas?

CompoundFile support in .NET framework 2.0
Hi,
The following links talk about .NET Compound Files in the .NET Framework
System.IO.CompoundFile namespace:
http://msdn.microsoft.com/longhorn/?pull=/library/en-us/dnlong/html/avalon-edocs.asp#edocs_topic7
http://www.winfx247.com/247reference/namespaces.aspx
I have just loaded the Visual Studio 2005 Beta, and MSDN Library for Visual
Studio 2005 Beta, and could not find any reference to the
System.IO.CompoundFile namespace.
Will this namespace be available in the release version of the .NET
Framework version 2, and where can I get a copy of the .NET Framework which
includes the CompoundFile support?

Terminating a thread from the main thread
Hello,
I have created a thread that writes data from a memorystream to the
harddrive. If the user, during the write decides to cancel the operation, I
call Abort on the thread.
i.e.
Private Sub WriteToDiskButton_Click
MyThread= New Threading.Thread(AddressOf WriteToDisk)
MyThread.Start()
End Sub
Private Sub WriteToDisk
Try
'do stuff
Catch Ex as System.Threading.ThreadAbortException
End Try
End Sub
Private Sub AbortButton_Click
MyThread.Abort
End Sub
When the Abort takes place I get two Abort Exceptions, I am able to catch
the fist one but how do I catch both exceptions so the user is not aware of
them.

Configuration Management Application Block multiple hashtables
Hi,
I'm using the CMAB and I'm trying to have more then one section of hashtable
in the config file. The way I do it, I get a validation error: "The same
table (XmlSerializableHashtable) cannot be the child table in two nested
relations".
Under the configsection I have a config elemnt for each of my hashtable
sections. Also under the applicationConfigurationManagement I have a
configsection element for each hashtable section.
What would be the way to have more that one hashtables defined in the config
file?
Thanks,
