windows service
Hi,
I have created a Windows service. In the project there is one service and
one installer. I have also created a Setup project. When I run my msi file
the service will not be installet into the Computer Manager/Service... the
application are installed into the Porgram Files/MyApp folder.
How can I trouble shoot this?

Word wrapping in Graphics.DrawString breaks words at umlauts
Hi,
I use Graphics.DrawString(string, Font, Brush, Rectangle, StringFormat) to
render a string inside a rectangle with word wrapping. It works fine so far,
but:
If words contain german umlauts (ä, ö, ü etc.), lines are broken before or
after these characters. The umlauts seem to be considered as delimiter
characters.
I can't find a language setting in the Graphics class or in the StringFormat
class either. I tried to set
stringFormat.SetDigitSubstitution(System.Globalization.CultureInfo.InstalledUICulture.LCID,StringDigitSubstitute.Traditional);
but to no effect.
TIA

Line numbers of methods in dynamically generated assemblies
Hello,
I am dynamically compiling .cs files to In-Memory assemblies at runtime
using CodeDom. This works fine.
The resulting assembly is parsed via reflection to detect the implemented
class and the the methods of that class. This works fine, too.
Now, I want to match the detected methods to the responding lines of code of
the original source file. This is the problem!
Maybee I have overseen something, but after a hard day trying to understand
and use the System.Diagnostics.SymbolStore namespace, I am completely stuck.
The methods of the SymbolStore seem to be only partially implemented and they
are quite poorly documented.
Does anyone have an idea how to get the line numbers of the first and the
last line of a method, from which I have the MethodInfo?
Any idea is greatly appreciated!
Thanks in advance

Cost of using functions [vb.net]
I was wondering if the use of functions decreases performance over placing
all code after each other.
For example: Instead of having function write anything to the screen using
Response.Write(strMessage), I usually call a function DisplayMessage
(strMessage), but now I'm wondering if this has any impact on the
performance, or does the Framework recode (or how it is called) this to
effecient code anyway.
The main advantage is that, if I decide that those functions should not
write anything to screen, I just have to disable that in only one place.
Plus readability is increased :)
Merely curious, as it is not really a performance issue, I'm wondering what
the groups thoughts are about this.

Problem deploying C# application with ClickOnce
Hi all,
I've created a simple application in C# to test for ClickOnce
deployment. After I've compiled the exe, I created the deployment
manifest and the application manifest with "mageui.exe", and then put it
onto a folder which could be recognized by IIS.
I tried to click on the .application file in Windows Explorer, and the
application is installed with no problem. Then I tried to do the same
thing through a web browser, typing the URL directly. The update screen
comes out normally, but after that an error message telling me that
"Unable to continue. The application is improperly formatted. Please
contact the vendor." is shown. The exception is attached at the end of
this message.
Since the XML files are created by mageui.exe without being modified, I
think they should have no formatting problem. And I have already
specified the Publisher. So is there anything that could cause this
problem? (FYI I'm using English WinXP, and have my default language for
non-Unicode programs set to Chinese (Taiwan)).
Thank you.

I miss those old events in this brave new world!
This is just a comment.
I was very surprised to find out that there are no named events support in
.NET framework! Sure, mutex objects can do most of IPC work, but there are
some cases that mutexes do not fit in (because mutexes have a unique thread
ownership feature).
For example (this may be very hard to understand, just like all other
synchronizing problems):
1. A parent process spawns a child process to do a job.
2. The parent has to make sure that the child starts the job or the child
exits prematurely on errors. It also has to have a way to tell the child to
stop working.
3. So in this brave .NET world, I have only one choice - two mutexes for the
IPC. One is for 'quit' signal, the other is for 'error' signal (when errors
occur, the child process exits).
4. Now the parent has the following logic:
get_unique_signal_names(); // Guid is used
create_quit_signal(); // intially owned
create_error_signal(); // not initially owned;
create_child_process_config(); // create a config file for the child
process
create_child_process_with_config(); // spawn the child process with
created config file
wait_for_child_process_or_error_signal(); // wait any of them
if(process exited)
{
call_error_handler();
}
else
{
user_ineration(); // provide UI to let user stop child process
}
5. The child process does this logic:
get_signal_names_from_config(); // they are in app.exe.config
open_quit_signal();
open_error_signal();
try
{
intialization_for_job();
}
catch(error)
{
set_error_signal();
return -1;
}
start_job(); // e.g., starting a listening socket
wait_for_quit_signal(); // enter wait state;
6. Everything is fine, right? But there is only one *small* problem. This
problem is caused by the unique feature of mutex objects - thead ownership.
Simply put, the above logic does not gurantee
wait_for_child_process_or_error_signal() always indicate the correct
situation.
The error signal is created not owned. Since no thread has ownership of
this mutex, its state is always *signaled*; unlike event objects, they are
either signaled or nonsignaled. So it is not 100% safe that when the code
gets to wait_for_child_process_or_error_signal(), the child process has
already does open_error_signal()!
It took me hours to find out this *small* problem. I think it's a small
problem because programs now runs on fast computers, the chance is very rare
for the child process get choked before open_error_signal() and while the
parent process gets to wait_for_child_process_or_error_signal().
7. There is a solution. But it is clumsy (anyone who gets to this point
please point out a good way if he/she know one):
For the parent process:
for(;;)
{
Thread.Sleep(500); // don't exhaust CPU time
// wait for the child process to get ownership of this signal
if(done_signal.WaitOne(500, true)) // in case the child already has it
{
done_signal.ReleaseMutex(); // well, have to do get/release in pairs
}
else break;
}
For the child process:
open_error_signal();
get_ownership_of_error_signal(); // get ownership - a simple wait
8. That's why I miss those named events in the ugly old world. With named
events, I don't have to add the logic in note 7.
At last, I finished it. I thank for any explanation on why named events
extinct in the new world (except the performance issue). Tag: Setting Printer Tag: 93740
Should I use XML or not?
Hello,
I am writing a word add-in in C#.
This add-in has to attach some metadata to bookmarks in the document. =
The metadata is stored in Word document variables.
Typical metadata can consist of a string identifier, three lists of [0 =
to 50] person-names each and about 5 Yes/No flags.
The problem is that I have to parse the metadata whenever the user moves =
the cursor onto bookmarked text so it has to be very fast, otherwise =
moving through the document will feel sluggish.
I was thinking of formatting the metadata using XmlTextWriter and =
parsing it using XmlTextReader.
However, I am not familiar with these classes and I am afraid that this =
approach may prove too slow on computers that are not state of the art.
The alternative is formatting and parsing the strings myself, perhaps =
using some combination of string.Split, string.Join, string.IndexOf and =
StringBuilder.
Since the metadata is only intended for the internal operation of the =
add-in, it can be as ugly as I want (in fact, I was thinking about =
obfuscating it do discourage users from messing with it but this may add =
another slowdown).
What would you suggest?
Thank you,

CreateProcessWithLogonW doesn't work with XP service pack 2
I posted this in another group, so, sorry if you have already read
this.
I'm trying to run an application under another user within a winform
app writen in C#. I have tried a number of different things, but it
seems that the CreateProcessWithLogonW function should work to do what
I need to do. This appears to work just fine in Windows 2000 and XP
with service pack 1, but it doesn't work with XP service pack 2
installed.
I'm sure it's one of the "Enhanced security features" of service pack
2, but I can't seem to get this to work. The function returns a 1
indicating that it worked fine, but the applcation that I'm trying
launch does not launch.
To give a little background on what I'm doing:
I have written a small app that is basically just an interface for the
netsh command to change network setting for the user. The users do not
have admin rights on their machines, but a select few need to be able
to change their IP addresses for buisness reasons. Because of this, I
basically just call the CreateProcessWithLogonW function to start run
the netsh command under an admin account on the machine to change the
IP address to whatever the user specifies in the interface that I
provided.
As a test, I have created two very simple windows apps. The first one
calls the CreateProcessWithLogonW function to login as another account
on the machine. It then calls another simple application that uses the
WindowsIdentity to show the current user. This works fine on Win2K and
XP sp1, but not with service pack 2.
If anyone know how to get around this, that would be great.

Question on - Automatic compilation of VB.NET files on a Web Server
Not sure if this is the correct newsgroup. Could be the IIS. Hopefully
someone can answer my question.
We are migration an ASP Web App to VB.NET. One of the benefits we're
enjoying so far with ASP is that we do not have to worry about a build
release. When an ASP file is modified and tested, we just deploy that file
to the production Web server through Visual SourceSafe without worrying that
we are releasing someone elses untested/unfinished code out.
Now I am hoping that .NET provides the same scenario where all we need to do
is copy the .aspx and .vb files to the Web Server, and all the .vb files
would automatically get compiled into the assembly when an .aspx file is
requested. Meaning that we wouldn't have to compile the application into a
DLL assembly. The environment would recognize that the .vb file has changed
and would get compiled into the existing assembly.
My question, does .NET work this way?
Thank you. Tag: Setting Printer Tag: 93724
Web Browser control throws exception when trying to navigate to ur
I have written a small app to help test code generated by Xslt
tranformations, these transformations are performed by various components -
basically this is a test rig for the components and Xslt they use.
All works fine the first time I invoke the method, save the output to file
and then browse to this file with the browser component. However, if I do
the same action again I get a "Exception has been thrown by the target of an
invocation." exception thrown when calling the Navigate() method (passing in
the same url as worked previously). The InnerException is "The requested
resource is in use.".
If I change the tool to point to a different component/xslt each time I
invoke the test then all is OK, it is just doing this when I do the same url
twice in a row.
I suspect it may be something to do with the some resources referenced in
the html not being available and the browser control not being ready for use
again - but why would it work for a different url?
Please help!!!

string which I want to parse using XmlTextReader. Can anyone give me
some pointers as to the best way to do it. Tag: Setting Printer Tag: 93703
CLR
I am new to .NET and going thru some books - these are the questions I have
1) When somebody says the process loads first CLR - "In .NET, executable
code must be loaded into the CLR to be managed while running" - what does it
mean? Is CLR a DLL? If so what is the name?
2) There used to be depends.exe in Visual Studio earlier that let us walk
thru all dlls loaded in an application? What is its equivalent in Visual
Studio 2003?
Thanks for the help

System.Web.Mail
How can I set sender and to adress of a MailMessage so that I have both the
email address and the sender's proper name.
Would something like this work?

Plugin assembles best practices
This is a lengthy post; please bear with me...
This will be a large system with dozens of plugins. In addition to plugins
developed internally there will be 3rd parties that will write their own and
integrate them into our application. I will be managing the identification
and loading of these plugins. In addition, there are a number of assemblies
that plugins will reference, some shared, and others private.
There are a couple of approaches I am considering.
It is expected that all plugins will need to be registered so that the app
does not blindly load up
all assemblies searching for plugins to load.
FIRST OPTION - separate directories
The expected directory layout is like this...
BaseDirectory (application)
PluginManifest.xml (info on which ones to load)
|
|
-- Common (shared.dll, all versions forced to latest)
|
|
-- PlugIn1 directory (Plugin1.dll, private1.dll, v1.0)
|
|
-- PlugIn2 directory (Plugin2.dll, private1.dll, v1.1)
|
|
-- PlugIn3 directory (Plugin3.dll, private1.dll, v1.2)
All assemblies that share types are to be relocated to the common
directory. This occurs when the
assembly is installed. This involves determining if an assembly is intended
to be shared - this
implies that the assembly is exporting a type that the consumer of that
assembly (i.e. the plugin) is
also exporting or importing.
All shared assemblies will have binding redirects so that all other
assemblies will all be pointing
at the same one.
All assemblies that are intended to be private will remain in the
subdirectory of the plugin. A codebase hint
for each assembly to be loaded will be placed into the app.config file so
that the assembly lives in the fusion load context.
ALTERNATIVE:
Put all assemblies into the same directory and enforce a naming convention
like this...
<namespace>.<asmName>.<version>.dll
This is intended to result in all assemblies having a unique name; the
name to include the assembly
version number.
No binding redirects to be done, nor will codebase hints be used, unless
there is a common assembly that
all others must share. This will be identified manually and a binding
redirect put into the app.config file.
The layout looks like this...
BaseDirectory
PluginManifest.xml (info on which ones to load)
|
shared.v1.0.dll, shared.v1.1.dll, shared.v1.2.dll,
|
|
PlugIn1.dll
PlugIn2.dll
PlugIn3.dll
private1.v1.0.dll
private1.v1.1.dll
private1.v1.2.dll
PROS and CONS:
Separate directories.
PROS
Prevents clutter. Makes it easier to separate "system" *(i.e. our)
assemblies from addins, 3rd parties,
etc.
Ensures that all private assemblies remain that way as they are isolated
by directories.
There is no global naming scheme we need to maintain or enforce.
Each plugin can have separate associated data files. Can use its own
subdirectories.
No naming conflicts.
CONS
Much more overhead in managing the system. I have to write a fusion-like
layer to handle all
the locations that assemblies can be in, the binding redirects, etc.
All plugins need to be analyzed for common items during the registration
process.
One directory
PROS:
Has the advantage of simplicity. Easy to locate and load assemblies.
No fusion-like layer to manage the assemblies is needed.
CONS
Requires a global naming scheme that everyone must adhere to.
Each plugin may be using a different version of an assembly and there is
no way to tell which one
is using what since they are all located in the same directory.
Identifying conflicts will be a nightmare.
If an assembly accidentally exports a type that is supposed to be private
will result in an error (typecase)
that will be very hard to troubleshoot.
Will be hard to "know" what assemblies are actually used and needed.
Clutters the directory.
If a plugin uses a data file may result in a name conflict with another
plugin.
So, anyone have any comments? Which method would be best? What other methods
are there that I did not mention?
Thanks,

DataGrid
I have a problem with datagrid in .Net FW v1.0.
I am performing communication with meters. I need to prepare the test
conditions, for which I am entering the data from datagrid, and storing in
XML,
while performing the test the test conditions are displayed in the Datagrid,
which is readonly. When each test is finished the current row index is
increamented by one so that it shows the current test condition.
If the test conditions are more than the size of the datagrid ie when the
datagrid becomes scrollable.
I get a message from Just-In-Time Debugger
Kindly help me telling what the problem is

Control Visiblity Issue-Is this a bug?
Hi guys.Consider the following situation:
There is a panel on a form whose visible property is set to false(I mean it
is invisible
when it is created.)
there is a button on this panel which when pressed,shows a modal
form(ShowDialog function).
if we set panel's visible property to "True" at run time,and then press the
button,the modal form is displayed,but when you close the modal form,an
exception is thrown with the following message:
"An error has occured in the application"-it says something like
"SEHException".
I'm becoming angry now,since I encounter many of these situations.Is it a
bug?and
if it is,do you have any solution? Tag: Setting Printer Tag: 93692
What is a synchronization domain?
Can anyone tell me what is a synchronization domain? Or you can also direct
me to a good article.
<quote_from_msdn>
Waits for any of the elements in the specified array to receive a signal,
using a 32-bit signed integer to measure the time interval, and specifying
whether to exit the synchronization domain before the wait.
[Visual Basic]
Overloads Public Shared Function WaitAny( _
ByVal waitHandles() As WaitHandle, _
ByVal millisecondsTimeout As Integer, _
ByVal exitContext As Boolean _
) As Integer
[C#]
public static int WaitAny(
WaitHandle[] waitHandles,
int millisecondsTimeout,
bool exitContext
);
Parameters
waitHandles
A WaitHandle array containing the objects for which the current instance
will wait.
millisecondsTimeout
The number of milliseconds to wait, or Timeout.Infinite (-1) to wait
indefinitely.
exitContext
true to exit the synchronization domain for the context before the wait (if
in a synchronized context), and reacquire it; otherwise, false.

GAC question: Will a newer version be used for an application?
I found several articles about GAC, but none of them can answer my question
(perhaps I am reading too fast :-)).
Suppose I have an application that is built against a shared assembly
version 1.0. That asembly is installed to GAC. Later a newer version of the
shared assembly is installed, say 1.1.
I want to know:
1. If the runtime will automatically select the newer version for the
application (not rebuilt).
2. Or do I need to rebuild it in order to use the newer version.
