    - 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.

    - 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 Uli Tag: windows service Tag: 93820

    - 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. -- Message posted via http://www.dotnetmonster.com Tag: windows service Tag: 93817

    - 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 have marked the class as serializable, however the object will not deserialize correctly (error: "The constructor to deserialize an object of type xMapNodeSerialize.MapNode was not found").

    - Producer/Consumer example I am building an application where data is coming in from a hardware deveice attached to the serial port. The data needs to be queued ASAP. I figured a could create a custom class containing this data and store it in an ArrayList for future processing. I want to process this data continually so that is could be preserved in case of a system failure. I was thinking of implement a producer/consumer relationship using threading. However, I haven't been able to find an example that explains things in a way that I can digest. Does anyone know of any good resources for developing producer/consumer systems with C# and Threading?

I can see from Task Manager that my app is chewing up memory (over 1GB) just before I get this error. I've have double checked all my code and i'm closing all DB connections and memory streams etc so in theory there should be no memory leaks.

    - 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: windows service 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, Alex. --=20 Please replace myrealbox with alexoren to reply by email. Tag: windows service Tag: 93734

    - 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. Thanks, Jerry Tag: windows service Tag: 93730

    - 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: windows service 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?

    - 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, David Levine Tag: windows service Tag: 93694

    - 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 -- Regards Sandeep Tag: windows service Tag: 93693

    - 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: windows service 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. </quote_from_msdn> Tag: windows service Tag: 93685

    - 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. Thanks.

    - Abount DESCryptoServiceProvider Can I de-crypt the data by java which is crypt by DESCryptoServiceProvider? The following is my code to crypt data: string text = "This is My source data"; byte[] source = System.Text.Encoding.Unicode.GetBytes(text); DESCryptoServiceProvider des = new DESCryptoServiceProvider(); des.Key = this.key; des.IV = this.iv; ICryptoTransform desencrypt = des.CreateEncryptor(); System.IO.MemoryStream ms = new System.IO.MemoryStream(); CryptoStream cryptostream = new CryptoStream(ms,desencrypt,CryptoStreamMode.Write); cryptostream.Write(source, 0, source.Length); byte[] result = ms.ToArray(); cryptostream.Close(); ms.Close(); And then, I will send the release data(result) to other host via http connection. And the remote host platform is java. Could the java platform decrypt the data I sent to? Thanks! Tag: windows service Tag: 93677

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?

Thanks
Julia

Julia,

Even if it's a Windows service is normal that you would find the application
installed in the Program Files folder. It seems that your installer isn't
run during the setup.

Make sure that the installer class has the RunInstaller attribute set to
true:

[RunInstaller(true)]
public class ProjectInstaller : System.Configuration.Install.Installer
{
...

If you still have problems, try this post:
