    - communicate between two exe applications Hi, There are are two app,named App1 and App2. When run App1, it will run App2 automatically. On the other hand, when terminate App1, App2 will aslo be terminated. I think App1 and App2 in a different domain, how to communicate them? I don't want to use process.kill() method to find and kill app2 process when App1 terminated. does "delegate" can do it? Tag: Sending chr(255) to serial port Tag: 119791

    - SaveFileDialog translation issue Hi all. In my application I use SaveFileDialog as follows. SaveFileDialog exportFileDialog = new SaveFileDialog(); exportFileDialog.Filter = "csv files (*.csv)|*.csv"; exportFileDialog.RestoreDirectory = true ; exportFileDialog.CreatePrompt = true; Since I have enabled CreatePrompt to true, for every new file am prompted with a message box with the following message. "C:\xyx.csv" does not exist. Do you want to create it?" My issues is that, when I execute this application in French Windows XP, title and the buttons of this message box are translated to French but the above message is in English. I don't understand why this message ("...does not exist. Do you want to create it?") is not translated to French? Title was translated to "Enregistrer sous" and OK and cancel was translated to "Oui" & "Non". Thanks in advance. SaveFileDialog translation issue Tag: Sending chr(255) to serial port Tag: 119790

    - Launching and Monitoring Executables I have a Windows Service I am writing in C# and a set of, let us say three, other executables written in C# (mostly console applications). I want that the Windows Service must do so every few seconds: Check to see if each of the other executables are running or not. If they are not running, it should load them. For this purpose, I am planning the following: I'll take a timer object and set it to an appropriate interval. In the timer's timer/elapsed event, I will check if the other executables are running or not. For checking that, I can use either of the following approaches: 1. Use OpenProcess/CreateProcess with LP_SECURITY_ATTRIBUTES set to NULL and with PROCESS_INFO. This will give me everything I need to know, like, the threadID, the processID, in order to determine if the process is running or not. The processID will be constant throughout the life of each process. This will help me check if a process is running or not. 2. ShellExecute/ShellExecuteEx - I am not sure if this is the right approach. If I am assuming correctly, ShellExecuteEx only sets GetLastError and returns a bool/int indicating success or failure. This may not be the approach I might want to take as this will not give me any information as to the status of the executable I have launched. Besides, even semantically, this method might not be suited for the purpose I have at hand, which is not to "launch documents in their associated application." 3. Create a new app domain for each process I want to launch, add all the appDomains to the same process, call ExecuteAssembly the Application Domain for each executable I want to launch. However, with the third approach, my knowledge of application domains is still limited. I have a couple of questions in this regard. a. Given that all this checking will be performed by a Windows Service, which is not really a Win32 process, like ordinary Windows PE files or executables, whether managed or unmanaged, what are the implications of creating appdomains from within a Windows service? Is it an alright thing to do to launch other Win32 processes from within a Windows service? b. Would it be possible for me to monitor the lifetime of an executable which I execute inside an application domain? Remember that my main purpose is to monitor in a timer if an application is running or not, and if not, to launch it again. c. What is the difference between System.AppDomain.Load() and System.AppDomain.ExecuteAssembly()? Sorry, I am being lazy here, but it is easier to ask a forum. I'm on my way to the MSDN, anyway. But kindly oblige. Thanks very much for your thoughts. Tag: Sending chr(255) to serial port Tag: 119789

    - Intra-thread lock Hi Is there something like an intra-thread lock? I'm trying to prevent re-entrant code, and the lock statement will only prevent one thread from entering the critical section while another thread is in it - since my code is triggered by a gui event, it's not impossible that it could be called twice from the same thread. I could simulate a lock by having a private variable "busy" and setting that to true when I start processing, false when I stop, and check it before I begin processing - but then either I have to throw an exception if I'm already busy processing (which I'd prefer not to do), or I'd have to use a polling wait loop to simulate a blocking call - which seems ugly. Any ideas of a better way to do this? Thanks Tag: Sending chr(255) to serial port Tag: 119755

    - Convert asynchronous to synchronous Hi I have a method which I want to present as a synchronous call - you pass in your parameters, and the result as a return value. But within that method, I need to spin off a thread, wait for it to finish doing some stuff, and return a value to the calling method. The problem is that my method may be called on the gui thread (since it's out of my control where my method is called from), and the gui will become unresponsive while my method is running if I wait for the thread to finish using Thread.Join. So what I'm doing at the moment is a loop like this: while (Thread.IsAlive) { Thread.Sleep(100); Application.DoEvents(); } Now I know that using Application.DoEvents like that is horrible, but I can't see any other way to wait for the thread to finish before returning the value to the calling method. Sure, I could pass the thread a delegate to call when it's finished, but I want the whole process to appear to be synchronous to the calling method. Is there a better way to accomplish this?

    - MSBuild heirarchy of projects like corext I'd like to use msbuild to build on a heirarchy of projects, based on the directory structure of the sources like CoreXt does. Is there a good way to do this? I'd like to have some folders where external libraries are located, and some folders where some libraries are built. Further, I'd like to have other projects which depend on some of these libraries, and also depend on each other. I'd like to organize these projects in seperate folders, but I dont' want to have a master "Solution" file which knows about all of these. I would like to have each project as an independent entity and allow the build to be started from anywhere in this heirarchy. For example, a root directory would contain several subdirectories, each of which would contain several projects, or even more subdirectories with more projects. I like the notion of the corext dirs file which allows independently adding/removing projects from the "build" by just editing the dirs file in the projects parent directory. Is there a good way of doing this with msbuild? If msbuild does not support this sort of thing, will it in the future? -- Jaan Tag: Sending chr(255) to serial port Tag: 119744

    - Possible VS2003 c# compiler bug: error CS0584: Internal Compiler Error: stage 'COMPILE' symbol '' Hi everybody! It's the second time it happens to me... Working with typed DataSets and doing copy & paste, I compile and get weirds messages like these: An internal error has occurred in the compiler. To work around this problem, try simplifying or changing the program near the locations listed below. Locations at the top of the list are closer to the point at which the internal error occurred. error CS0584: Internal Compiler Error: stage 'BIND' symbol 'WindowsApplication1.Form1.Form1_Load(object, System.EventArgs)' error CS0584: Internal Compiler Error: stage 'COMPILE' symbol 'WindowsApplication1.Form1' error CS0584: Internal Compiler Error: stage 'COMPILE' symbol 'WindowsApplication1' error CS0584: Internal Compiler Error: stage 'COMPILE' symbol '' error CS0586: Internal Compiler Error: stage 'COMPILE' Once you get one of these you must exit VS2003, because the compiler does not work anymore... Here is how to reproduce it: Create a Solution, with 2 projects, one client app and one class library. In the class library proyect add a typed Dataset, and a class with a method like this: public MyDataset FakeFunction (MyDataset.ClassificationDataTable table) { return new MyDataset(); } In the client app, call the method in this way (here's where the error is): MyDataset ds2 = MyClass.FakeFunction(ds.ClassificationDataTable); That is you miss it doing copy-paste, you should have written: MyDataset ds2 = MyClass.FakeFunction(ds.Classification); And you got the evil messages, very descriptive, aren't they? The curious thing about it is that if you place the class with the method and the Dataset in the client app proyect, the error message is accourate, so the error only happens when referencing another project: error CS0572: 'ClassificationDataTable': cannot reference a type through an expression; try 'ClassLibrary1.MyDataset.ClassificationDataTable' instead Tag: Sending chr(255) to serial port Tag: 119743

    - Single or multiple assemblies for big apps and code reuse? Hi everyone, I have a question about .NET code sharing and reuse, and also about application design best practices / guidelines. Currently, we have many different .NET projects in source depot. Although they are different, in some of them we share C# code by referencing source files that are external (not part of the projects) on each project. For instance, some of our projects have the typical â??sourcesâ?? file with: SOURCES = \ ..\..\some_other_different_unrelated_project_A\fileA1.cs \ ..\..\some_other_different_unrelated_project_B\fileB1.cs \ ..\..\some_other_different_unrelated_project_B\fileB2.cs \ Program.cs Class.cs And so on. Some people in my team think that DLLs and assemblies are evil and should be completely avoided. Therefore, they advocate treating all projects in the depot as one huge, monolithic project (even they are not, as they are different projects), sharing code by referencing source files all over the depot. Basically, each application has one and only one assembly containing all the application source code plus all source code that belong to other projects too but is reused by referencing the other project(s) C# source files. Other team members (BTW facing huge opposition) insist in packing the shareable code into one or more assemblies, although for some people, assemblies and DLLs are absolutely forbidden. Can someone please tell me the pros and cons of each approach? Is it right to be completely against packing certain substantial modules or pieces of functionality into separated assembly/assemblies, as opposed to having one and only one single, huge monolithic assembly containing the whole application + other project source files? Those in favor of having shareable code packed into separate assemblies, instead of putting everything (all the source code of the application plus the sources of our libraries, plus the sources of all subsystems, etc.) into one, big monolithic assembly, point to these other URIs: http://msdn.microsoft.com/practices/compcat/default.aspx?pull=/library/en-us/dnbda/html/distapp.asp http://msdn.microsoft.com/practices/compcat/default.aspx?pull=/library/en-us/dnbda/html/apparchch2.asp http://weblogs.asp.net/savanness/archive/2003/07/22/10417.aspx http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconassembliesoverview.asp So, I wonder, are there any guidelines and/or best practices/patterns/anti-patterns in regards to C# source code sharing and reusing among different projects? Any authoritative answers? Is it reassonable to build big, different applications from one huge source tree, having only one and just one assembly per application and nothing more? Or it makes more sense to split the app into multiple assemblies, but keeping the number of assemblies to a minimum? Thanks and regards, Claudio Tag: Sending chr(255) to serial port Tag: 119736

Since I am using IE as control in .net 2.0 and using some extension to it found on codeproject site, I want to handle all browser UI with my dialogs, but unfortunately event that is supposed to be firing doesn't fire. It is WindowClosing event, that even has cancel parameter. My ideas: 1. find out if there is some hidden property inside Internet Explorer registry that would default the dialog box to yes or to no (no success there) 2. find if there is a way to use Navigate() to the url, then use some event that is fired after the document is loaded but before the script runs (no success there either) 3. make local proxy server that would filter out window.close from the script Am I missing something, please advise.

    - Finally, handling resizes and and MDI's scrollbar. Been trying to figure out how to resize forms indside an MDI Form, when the form itself is resized dynamically, to maximize and anchors do not help. The problem was getting the size of the scrollbars, and effecting the resize at the right time. For me, the answer was finding the MDIClient and AddHandlering its Layout event. MDIClient is the client area inside the MDI form, in my case, without a scrollbar, MDIClient.ClientRectangle.Width was 4 less the MDI.Rectangle.Width (must be two pixels for each of the MDI's borders). With a scrollbar it jumped to 20 (likely the scrollbar is 16 pixels wide). Getting the MDIClient (as found in the newsgroups) is done with a ForEach cycling through all controls in the MDI's control collection and finding the one with the type MDIClient. Should probably be index of 0, unless the user makes it an MDI in the code after other controls are added. The second thing was handling those scrollbars. That is done by the MDIClient's layout event, at which time, the scrollbars et al have been taken into account. Since the MDIClient is not there right away, the Handler must be refered to in the code. The declaration of the MDIClient's Layout event is the same as the MDI's Layout event. B.

The code is as follows: jScript = "<script LANGUAGE=""javascript"">" & vbNewLine jScript = jScript & "function ToggleDiv(id){" & vbNewLine jScript = jScript & "var elem = document.getElementById(id);" & vbNewLine jScript = jScript & "if (elem)" & vbNewLine jScript = jScript & "{" & vbNewLine jScript = jScript & " if (elem.style.display != 'block')" & vbNewLine jScript = jScript & " {" & vbNewLine jScript = jScript & " elem.style.display = 'block';" & vbNewLine jScript = jScript & " elem.style.visibility = 'visible';" & vbNewLine jScript = jScript & " }" & vbNewLine jScript = jScript & " else" & vbNewLine jScript = jScript & " {" & vbNewLine jScript = jScript & " elem.style.display = 'none';" & vbNewLine jScript = jScript & " elem.style.visibility = 'hidden';" & vbNewLine jScript = jScript & " }" & vbNewLine jScript = jScript & " }" & vbNewLine jScript = jScript & "}" & vbNewLine jScript = jScript & "ToggleDiv('Page_Div');" & vbNewLine jScript = jScript & "</sc" & "ript>" Response.Write(jScript) I dont get any errors, but the javascript doesn't execute either.

    - Microsoft .NET Framework 2.0 Configuration OK, I have done a .NET 2.0 Framework install and under the Administrative Tools I am not getting the Microsoft .NET Framework 2.0 Configuration application. I looked for any MSC files in the V2.0.50727 directory and nothing exists. We are installing the .NET 2.0 Framework as part of our application. Why is this tool missing and how do I get it back? Our customers may need to reconfigure some of the settings this provides. Thanks, Eric Renken Tag: Sending chr(255) to serial port Tag: 119695

Surely this functionality could be packaged into and API and integrated with Windows Authentication. I know my users would be well served by logging in with a fingerprint scan rather than tapping out a secure password into the SIP. Bill Tag: Sending chr(255) to serial port Tag: 119693

    - xsd.exe and Enums Hallo, I have used the xsd.exe tool a year ago (version 1.1.4322.2032) to generate a vb class to serialize xml. All string enums in the xml are availible in the vb code as strings. If I use the same tool today the code is different to that a year ago - especially the enums are different. Now I get Integer values for enums which are strings. I have to use .ToString to get the string value. Why ist that different? regards Tag: Sending chr(255) to serial port Tag: 119687

    - System.Version Hi All, I've searched the documentation and Google for an answer to this but to no avail. It seems that System.Version does not serialize to XML. I checked the documentation and this type is flagged as being Serializable, it has a default parameterless constructor, and I'm pretty sure it can be binarily serialized without a problem. On my example class I have a field as follows: Public MyVersion As System.Version I initialise this to a new System.Version(5,5,5,5) before serializing. After serializing it to an XML file using the XMLSerializer class all I get in my XML doc is "<MyVersion />" - this seems to imply that none of the fields in the System.Version class can be serialized into XML? Can anyone confirm this? Thanks, Alex Clark Tag: Sending chr(255) to serial port Tag: 119677

    - Blocking memorystream, does it exists? Hi I'm looking for something like a blocking memorystream, ie. a memorystream that will block any further writes when the internal buffer is full, until data is read. What I want to do, it to apply some conversion to an XML file when I read it, and then right away (in another thread) read the converted stream using an xmltextreader.

    - Windows service not starting at boot time Hello: I'm currently developing a windows service, and in OnStart i launch a couple of threads to do some work. When i start it manually everything goes fine, but at start up the service just timeout. I have added all the dependencies i thought could be used by the service, included eventlog, rpc, sqlserver. Is there any way to get the service dependencies all? Or is there any detailed log of what is going on on startup? The timeout message in eventlog says nothing about the cause.

    - Async Sockets, pinned objects and .NET 2.0 Hi, I am migrating an application from .NET 1.1 to .NET 2.0. It is a network application that use asynchronous sockets intensively (with more than 300 active connections on average) With .NET 1.1 I had problems because the buffers used in the BeginReceive and BeginSend calls were pinned and prevented the heap to be compacted by the GC. I managed to solve this problem by allocating the buffers at the application start up using a buffer pool. Now, in the same application, compiled with .NET 2.0 the heap is heavily fragmented. I can see with perfmon that the pinned objects counter is about 4 times the number of pending asynchronous calls (it was exactly equal in .Net 1.1), so it seems that .NET 2.0 pins 4 objects for each asynchronous socket call instead of pinning only the buffer. This make senseless the approach of using a buffer pool (I get the same memory footprint in .NET 2.0 using the buffer pool or not using it). And the improvements done in .NET 2.0 in managing pinned objects are not good enough, so the situation became worse. Am I wrong with this conclusion? If not, Is there any workaround for this? or a way I can do that the asynchronous socket calls pins only the sending/receiving buffer? What other objects is .NET 2.0 pinning in the asyn socket calls?

    - Hashtable.Add fails Hi all, I want to assign a new key value to my hash table (okay, I use the Specialized.NameValueCollection, but this collection is based again on the HashTable). When the key already exists, then the value of the key shall be replaced. That's why I use the Add method which also replaces key values instead of Insert which fires exceptions when a key already exist. Now, I've got a very strange exception: ----SNIP---- System.ArgumentException: Das Element wurde bereits hinzugefÃ¼gt. SchlÃ¼ssel im WÃ¶rterbuch: "color_anchor_NavHeader2_all" HinzuzufÃ¼gender SchlÃ¼ssel: "color_anchor_NavHeader2_all" at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add) at System.Collections.Hashtable.Add(Object key, Object value) at System.Collections.Specialized.NameObjectCollectionBase.BaseAdd(String name, Object value) at System.Collections.Specialized.NameObjectCollectionBase.BaseSet(String name, Object value) at System.Collections.Specialized.NameValueCollection.Set(String name, String value) at System.Collections.Specialized.NameValueCollection.set_Item(String name, String value) at BOMAG.CorporateWebSite.DealerCustomizing.LoadDealerConfigurationSetting(String propertyName, DealerLookupModes dealerLookupMode) at _ASP.style_aspx.__Render__control1(HtmlTextWriter __output, Control parameterContainer) at System.Web.UI.Control.RenderChildren(HtmlTextWriter writer) at System.Web.UI.Control.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderControl(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain() ----/SNIP---- The add method is called, it identifies the key as missing and that's why it calls the Insert method internally. Then, the Insert method wants to insert the key - but by whatever reason, the insert fails because the key already exist. Somewhere between the execution of the IF in the Add method and the key-insertion in Insert, the key must have been created. So, I can only imaging that another process (very normal for web solutions) might be more fast and inserted the key value in the meanwhile. Is this a bug or is it a feature? Thanks for any advise!

Hi

I need to send a chr(255) to a serial port. When I send it, through
comm.write (chr(255)) it sends a chr(63) ... in Hex, I write chr(&FF) and it
actually sends chr(&3F) ... why does this happen, and how can I send it
right ?

I'm using vb.net 2005 express with framework 2.0

Not sure this will help as I am pretty new to this topic as well. But what is
the value of the serial port's DataBits property? The docs say the default
should be 8. But you never know...
