    - Threading and raising events hello, I'm using C# and having a little thread communication problem : -one thread (and its associated object) receives UDP packets using the UdpClient class -another object (say Object2) needs to raise an event from another thread when a packet is received. -as Object2 *could* be sitting on the main thread, it cannot be blocked waiting on the "UdpThread" -Object2 is not a System.Window.Forms.Control -I'd rather avoid polling some synchronized variable. in the good old win32 times, i would have allocated a window handle in Object2's thread and used PostMessage from the UdpThread.=> no polling and no locking... Any advice on what should be done to remain in the .NET spirit while achieving such goals ? thanks in advance Sacha De Vos Tag: scheduling Tag: 75538

    - HideEditBox in a DataGrid. Please Help. Hi All, Has anyone out there used HideEditBox, successfully? I am writing developing in VB .NET (VS .NET 2002) for the desktop. I have a datagrid which is ReadOnly. When you click in a cell, the text edit box appears which looks bad and distracts the user, AND it captures DoubleClick which I want to handle at the DataGrid level. I have set up a TableStyle and GridColumnStyles - all ReadOnly. I have created a new class for the columns, which inherits DataGridTextBoxColumn, and have called HideEditBox in the constructor. It does absolutely nothing. Here is the class: Public Class DataGridPassiveColumn Inherits DataGridTextBoxColumn Public Sub New() Me.HideEditBox() Me.Alignment = HorizontalAlignment.Right End Sub End Class ... I put the Alignment in there just to get some feedback so I know my class is working (I have to admit I'm new at this). The Alignment works, the HideEditBox does not. Can alybody help? I would appreciate it vey much. Randall Smallwood. Tag: scheduling Tag: 75530

    - TCPListener and Windows service Hi All I have a scenario The server can dial into the client for several task 1. To fetch several rows from 2 or 3 tables - I plan to zip the files and send it across the network; to increase performance, instead of row-by-row update on the serve 2. To execute a remote application on the client and fetch data returned by the client application to the serve 3. To transfer some files to the client which would be either stored on the client's hard disk, or execute an application and pass the file to the remote applicatio 4. To update sql data on the client databas My initial design was to make four TCPlistener exes listening to 4 ports and appropriately make the listeners to the appropriate jobs depending on the port that receives data Is it possible for me to have just one windows service to be running on the client, and depending on the parameter sent from the server, do one of the four options stated above Please advise Thanks Tag: scheduling Tag: 75498

    - PerformanceCounter & PerformanceCounterCategory on Windows 2003 We are trying to create a custom performance counter and category in .Net 1.1 with Windows 2003 and XP as our operating systems. We use the following code to do this if (PerformanceCounterCategory.Exists(categoryName) PerformanceCounterCategory.Delete(categoryName) CounterCreationData ccd = new CounterCreationData(counterName, counterHelp, PerformanceCounterType.RateOfCountsPerSecond32) CounterCreationDataCollection ccdc = new CounterCreationDataCollection() ccdc.Add(ccd) PerformanceCounterCategory perfCategory = PerformanceCounterCategory.Create(categoryName, categoryHelp, ccdc) OurLibrary.Error.AssertThrow(perfCategory.CounterExists(counterName), String.Format("Expected \"{0}\" counter to exist.", counterName)) PerformanceCounter counter = new PerformanceCounter(categoryName, counterName, false) We get a "Category does not exist" InvalidOperationException when we assert that the counter exists. perfCategory != null at this time. The PerformanceCounterCategory.Create does NOT throw. We have tried many permutations of calls to try to get this to work, but it always throws. The odd thing is that the category and counter are actually created in the perfmon utility. We can see them from .net too, but not in the process that created them. We have tried this same code on Windows 2000 boxes and it works correctly. What is the problem with the Windows 2003 and XP operating systems that cause this to fail? We have searched the newsgroups and have not seen any explanations and very few instances of this problem. Are we the only ones using the .net performance counters Thanks Frank Tag: scheduling Tag: 75487

    - RSACryptoServiceProvider constructor very slow under Win XP I have a .NET app that uses the RSACryptoServiceProvider class to perform a key exchange with a server. During testing we've found that on some Windows XP machines, the call to the constructor for this class can take 15 or more seconds! On our Win 2K and Win 98 test machines it always takes less than 3 seconds. The problem's very easy to reproduce -- just create a console app with one line of code in it: RSACryptoServiceProvider p = new RSACryptoServiceProvider(); One most machines, this should run fairly quickly. On the afflicted machined, it's very slow. I know that the key generation goes on during the constructor, but 15 seconds...?!?! Also, as I said, this only affects SOME XP machines -- we have others that work just as the Win 2K boxes. To compare the XP machines that work fine to those that don't, we compared the advapi32.dll versions/dates, but they were identical. Has anyone else seen this issue or have any idea why XP would be so slow in generating running this constructor? Thanks for your help - Ken Tag: scheduling Tag: 75465

    - Security Policy, Code Groups and Security Tools. Could someone who has active experience of assigning Security Policys please clarify my follow comments... Having gone through the MSDN documentation on this subject, my condensed version of the way the security code permissions works is thus :- 1. An Assembly will be mapped to one or more Code Groups based upon the membership conditions specified within each code group. 2. When an assembly belongs to multiple code groups, permissions assigned by one code group can be overridden (increased) by permissions assigned by another code group when they are both part of the same Policy level. 3. Code groups from a lower policy level cannot override (increase) permissions set by an upper level (apart from when the permission hasnt yet been set) *but* can reduce them. 4. The user policy level code groups cannot grant additional permissions to an assembly *but* can only reduce them further. 5. When the Exclusive attribute is used on a code group, the code group will become the only one within that policy level to apply permissions, although the further policy levels code groups will be evaluated. When an application belongs to more than one Exclusive code group it will not be run. 6. When the Level Final attribute is used on a code group, no other policy levels code groups are evaluated *although* the current policy levels code groups will. 7. When Level Final and Exclusive are used together then the codegroup on that level will be the only one that will apply to the application through all policy levels. Couple of points. a. Firstly is there any reason that the code groups are / can be nested, from what I can see the answer is no -although I am assuming that it allows for a more specific targetting of conditions. b. Since the default Enterprise code group is All_Code -Full Trust and changing it could effectly cause problems with the framework, I assume this is left alone. Because this code group would override any additional code groups within this policy, I am assuming that all Enterprise level code groups should be marked as Exclusive. c. Does Caspol utility expose any additional functionality than mscorcfg utility (apart from the ability to do scripted config)?

    - Exception Handling and Loops Hi, I have a while loop where for each value I execute a database query. I have a situation where one of these queries abort due to bad data. I want the application to continue processing the loop for other values. I have tired what I thought would do this but it still aborts the application on error. I have a Manager class that has the while loop that calls a Data class that fromulates the parameters and the the right stored proc and that calls the MS. Data Access application block to execute the query The block of code in the manager class looks like this SqlDataReader drIDs = GetInformation(); while (drIDs.Read()) { int iId = drIDs.GetInt32(0); try { GenerateReport(iId); } catch (Exception e) { throw; continue; } } The error I get is .Net SQL Client Data Provider. Subquery returned more than one value. How do I skip the error and continue processing the loop for other values. TIA Tag: scheduling Tag: 75406

    - C Library Problem when using Managed Code The following line of code does not work when using the /clr option TCHAR *p = _tcsrchr(_T("Test\\String"), _T('\\')); if(p==NULL) AfxMessageBox(_T("Error")); If I disable the /clr option, the message box "Error" is not shown. My program is compiled to use the Unicode Charset and I have the macro UNICODE define. If I change the code to use multibyte charset it works fine. Does anyone know how to get this problem fixed? (CString ReverseFind has the same problem). Regards, Lourenço. Tag: scheduling Tag: 75401

    - Connecting to existing remote project Hello, I have searched all over for the answer to this, to no avail. I have a web project already set up and running on a remote server, that I created from my home computer. I am now trying to connect to it from my work computer, but cannot figure out how to set up the project. Here are the various methods I've already tried: 1) When I try Open > Project From Web, I type in the URL, and then it prompts me for a project to open, locally. The problem is, I don't have a project set up locally -- that's what I'm trying to do. 2) When I try New > Project > Empty Web Project, I type in the URL (for Location), it tells me "There is already a project created on the Web" -- which makes sense. 3) When I try New > Project > New Project In Existing Folder, I give it a project name, then tell it the URL, then it tells me "Cannot create the project. There is already a project with the name '/myproject.vbproj' on the Web 'http://myproject.com'." 4) So, I tried copying the project files from the server to my local machine, and then tried opening the project, or pointing the prompt from method #1 (above) to the copied project file, but it then tells me "Unable to open Web project '/'. The file path '<path to project file>' does not correspond to the URL 'http://Localhost:'. The two need to map to the same server location. HTTP Error 404: Object Not Found". So I'm stumped. What the heck am I doing wrong, and why am I not finding any info on this? Please relieve me of my frustration -- I would be very much appreciative! Thanks in advance. Tag: scheduling Tag: 75397

    - Controlling MDIChild forms Hi I kind of a new programmer. I started a few wees ago with Visual Basic .NET and I'm trying to develop a simple (I think) application with an MDIForm and an MDIChild. Thus, I open the Child form and it works fine but, when I close, using the close button (X) on the upper-right corner of its window, I canÂ´t mange to catch this event on the MDI Parent form, so I can redefine the MDI Form main menu again (show & hide some options) Can someone tell me a way so that the MDI Parent form knows when its child form has been closed (with the close button on the upper-right) Thank Paulo Tag: scheduling Tag: 75394

    - Loosing reference to Thread I need to have a thread run as long as it needs to, and not stop until it is cancelled by either closing the application or manually be stopped. It is simply pinging a machine to see what the connection speed is. The ping code is not the problem, as I have used it to get the speeds before, and it is solid What happens is that after the thread has been running awhile, it just stops. I cannot stop it, but when I restart the thread, it is fine. I don't mind restarting the thread, but I want it to do it automatically. Is there some code that I can put in to detect if the thread has gone awry? I have a button on the form that simply starts and stops the thread. If I leave the thread running too long, the code stops to work. When that happens, I stop the thread, and I get the 'Thread cannot be stopped' message box (see code below). Then I can restart the thread I used the code samples that the MSDN has to make it work. Here is the code I have now Public CancelThread As New System.Threading.ManualResetEvent(False Public ThreadisCanceled As New System.Threading.ManualResetEvent(False Private Sub SomeLongTask( ' Run code until CancelThread is set While Not CancelThread.WaitOne(0, False) ' Do some kind of task here System.Threading.Thread.Sleep(CSng(txtPingDelay.Text) * 1000) 'txtpingdelay = . ThreadPing( End Whil If CancelThread.WaitOne(0, False) The 'Acknowledge that the ManualResetEvent CancelThread is set ThreadisCanceled.Set( End I End Su Public Sub StartTask( ' Starts a new thread Dim th As New System.Threading.Thread(AddressOf SomeLongTask CancelThread.Reset( ThreadisCanceled.Reset( th.Start( End Su Public Sub CancelTask( ' Stops any threads started by the StartTask procedure ' Notice that this thread both receives and sends ' synchronization events to coordiante the threads. CancelThread.Set() ' Set CancelThread to ask the thread to stop If ThreadisCanceled.WaitOne(4000, False) The ' Wait up to 4 seconds for the thread to ' acknowledge that it has stopped Els MsgBox("The thread could not be stopped."

    - EventLog Source I used the EventLog class to create an Event Source under the Application log. That was a snap. In order to register custom event categories, it appears that you need to know the guiid of the event source. Is that correct? If so what is an easy way to determine the guid of the event source? Please advise. Thanks for your help. Best Regards, Paul J. Lay Tag: scheduling Tag: 75389

    - Passing active SessionID to a HttpWebRequest Hello there.... I try to call a aspx file within an running asxp file. The key thing is that I need to pass the active ASP.NET_SessionID to this new aspx file via HttpWebRequest.GetResponse Method. Then I want to read the whole thing with a stream object. The weird thing happen at Line 9, after the timeout (1sec) is over. ASP.NET throws an timeout exeption. Even when I set the timeout to 5 min, ASP is waiting always until a timeout expires If I implement a Try/Catch at line 9, after the timeout my debugger jumps to the new aspx file where I set a breakpoint. Also it uses the same session ID :) But the "objResponse" in line 9 is set to NOTHING and all the following code fail because of that. What do I have to do that the GetResponse Method works properly. Thanks Michael ********************My Code******************** 1 Dim objResponse As HttpWebResponse 2 Dim objRequest As HttpWebRequest 3 Dim sr As StreamReader 4 Dim result As String '**1 Create the Request object****************** 5 objRequest = System.Net.HttpWebRequest.Create("http://localhost/aidsgame/test_result.aspx") '***2 Add the container with the active sessionID*** 6 objRequest.CookieContainer = New System.Net.CookieContainer(50) 7 objRequest.CookieContainer.Add(New System.Uri("http://localhost/aidsgame"), New System.Net.Cookie("ASP.NET_SessionId", Request.Cookies("ASP.NET_SessionId").Value)) 8 objRequest.Timeout = 1000 9 objResponse = objRequest.GetResponse() <---throws timeout exeption 10 sr = New StreamReader(objResponse.GetResponseStream()) 11 result = sr.ReadToEnd() ' Close and clean up the StreamReader sr.Close() ******************************************** Tag: scheduling Tag: 75378

    - MDAC/ Dot.net clash Hi, I am having trouble getting an oledb provider to work in a dot.net page. I get the message : "The .Net Data OLE DB Provider(System.Data.OleDb) requires Microsoft Data Access Components(MDAC) version 2.6 or later" Running the component checker tells me i have MDAC 2.7 refresh installed but a detailed analysis shows a few dll's and registry keys that refer to 2.5. I guess I have a 2.5/2.7 hybrid that dot.net doesn't like. I have tried reinstalling MDAC 2.7 but it still has the same discrepancies. Should I try and install 2.5 then 2.7? Please let me know if there is a more appropriate group to ask this on. Cheers -- http://www.flashgorman.com Tag: scheduling Tag: 75372
