    - Framework 3.5 WSUS availability Its been 3 months since I last asked this question and little, nay no, information is avialable. My application is dependant upon features found in Framework 3,5 and its deployment is partially targeted to medium size organizations. So I'll ask again: Does anyone have a date or idea when .NET Framework 3.5 will be available for WSUS updates? -- Kenneth Lemieux Project Engineer Whelen Engineering Co., Inc.

    - Command Line compiler help Hello, I am trying to compile a Windows Forms project through command line. I have added some images on the buttons. These images are added as a resource and stored in the "Resource" directory inside the project directory. My project is quite small, (only a single form). I tried running csc in the same folder as my source files using command: csc /out:My.exe *.cs It obviously fails since I am not telling the compiler where my Resource files are. Error: EncoderWindow.Designer.cs(224,61): error CS0234: The type or namespace name 'Properties' does not exist in the namespace 'MPEGCompression' (are you missing an assembly reference?) Can you help me with the right command? (I tried a lot of combinations with /resource: option but without any luck). Thanks Tag: POS printer on LPT ready ?? Tag: 139181

    - WF Foundation & Multiple State Machines I have a system with three main components and each of these components is represented by a class. 1) A light source 2) A video camera 3) A motorized platform to move an object The user controls the light source (brightness, direction, etc), the motorized platform to move the object into different positions and the camera (framerate, sensitivity, etc). The video camera continuously shows the images. In this scenario all three components work mostly independently and in parallel (the user can adjust the light while the motor is still moving). Now there is an additional mode where the object can automatically be analyzed. The program automatically moves the object into different positions, adjusts the light and reads out the images at each position from the camera for processing. What is the best approach to implement all of this? I was thinking of using the WF Foundation. For the first case I could have three state machines. But then how could I make these state machines interact with each other for the second scenario? Also note that the end product is not necessary a full program but can also be an SDK where the user just sends commands to the different components and also has a command to start the automated analysis (without programing that part him/herself).

    - Looking for help with Framework update Hello, I am using Windows XP home edition version 2002 SP2 and my system has installed on it MS.NET Framework (English) V1.0.3705 MS.NET Framework 1.1 MS.NET Framework 1.1 Hotfix (KB928366) I have an update ready to install and when I try to do the install, after 30 or more seconds I get a message that reads The following updates were not installed: Microsoft .NET Framework 1.0 Service Pack 3, English Version I have tried to get help and the only thing I could find is at http://support.microsoft.com/kb/899619/ where it says that the installation of .Net Framework 1.0 Service Pack 3 (Kb867461) cannot be installed because you have one or more hot fixes installed. Remove them and try again. I removed the MS.NET Framework 1.1 Hotfix (KB928366) and tried to install the update again. The results were the same -- could not install and shortly afterwards the Hotfix reappeared in my system's Add/Remove programs list. I am getting desperate. Does anyone know what I must do get get this SP 3 update installed? Thanks in advance, Lee Tag: POS printer on LPT ready ?? Tag: 139171

    - SMTP Component Hello, I want to send with SMTP the eml files dropped by SmtpClient.Send when using a pickup directory (not IIS one). This can be useful for me as I send mails in several cases, included with SQL Express CLR procs, and I don't want (or it's not possible) to deal with asynchronous programming each time. Have you heard about such a component (a service) or do I have to program the SMTP protocol by myself ? Or any other idea I didn't have yet ?

    - clickonce crash / failure Our app uses the following chain of urls: 1. yoursite.com/launch.php?room=00000271 - validates the roomid appends an appropriate server variable and encrypts and adds a hash and sends on to #2 2. mysite.com/launch.php decodes the encryption and compares hash for alteration. Re-encodes and redirects to #3 3. clickonceinstaller.application?encoded variables here All redirects are done with: header("Cache-Control: no-cache"); header("Pragma: no-cache"); header('Location: ' . $url); If I open IE and type in the starting link I get the clickonce app with no problems.

    - WPF Application and windows display properties Hi, I am designing a window in WPF application. I want my WPF application to respond to the windows display properties (just like windows form application would). For example if I change the display to 'Brik' or 'Desert' the window should change colours accordingly. However, the Window which has a WPF User Control does not change its layout color to 'Brick' or 'Desert'. But the buttons do change color. How can I make my WPF application behave like anyother window application when it comes to layout coloring. I do not want to use any style. Thanks Rick Tag: POS printer on LPT ready ?? Tag: 139154

    - System.IO.StringReader ReadToEnd() I'm doing screen scraping from a Windows Application and dumping certain data into a SqlDb, it's one of our parent websites, through a Proxy server using the the WebClient class. I have used the WebRequest/Response classes but the only benefit I got from that was the abiliy to control the timeout on the WebResponse. I can control the timeout on the ProxyServer here and that's all I need. For the issue I'm having the code below should suffice: System.Net.WebClient wc = new System.Net.WebClient(); System.Net.WebProxy wp = new System.Net.WebProxy(); wp.UseDefaultCredentials = true; wc.Headers.Add("User-Agent", "Mozilla/4.0+"); wc.Proxy = wp; strm = wc.OpenRead(nextSubURL); System.IO.StreamReader sr = new System.IO.StreamReader(strm); System.IO.StringReader strReader = new System.IO.StringReader(sr.ReadToEnd()); Here's my problem, eventually I'm getting a timeout on sr.ReadToEnd. I'm not getting it everytime; could it be that some pages being dumed into the StreamReader are just to big? I know that I can't control that but if there a way to stop that from timing out? Thanks everyone. -- Kevin C. Brown Developer Tag: POS printer on LPT ready ?? Tag: 139152

    - HasExited() generates an Access Denied error I have a C# program that relies on a service (let's call it myService.exe). So I wrote a routine that makes sure the service is running: int iProcessID = IsProcessRunning("myService.exe"); Process myProcess = Process.GetProcessById(iProcessID); These commands work great (I can post the IsProcessRunning() code if necessary, but since that's not the issue I thought I'd leave it out). Here's where the code fails: I check to make sure the process is alive using this code while(!bShutdown) { myProcess.WaitForExit(500); if(myProcess.HasExited) { break; } else { // Periodic functions go here... } } On Windows XP the code works great. On Windows Vista the .HasExited property causes an Access Denied error. I'm sure it has something to do with permissions, but I haven't figured it out yet. Can anyone help?

    - Symantec Endpoint prevents .NetFramework programs from launching Hello, We have a few laptops, different Dell models using Windows XP SP2, that are having a problem with .Net 2.0 and Symantec Endpoint. Whenever a program that uses .NetFramework attempts to launch we receive errors, different errors depending on the program. An example is when I try to launch Virtual Infrastructure Client 2.0 (VMware client), I receive the error "VPXClient.exe - Fatal error". CLR error: 8007000b. The program will now terminate. I know that it has something to do with the permissions between Symantec Endpoint and .NetFramework because I can run the program using "run as" and using the domain administrators credentials. Also, If I uninstall Endpoint all the programs that were affected launch without any issue. I have already put a ticket in with Symantec and hope that they are able to resolve this issue. I just want to stay ahead of the game in case they say that it is not there issue. Just thought that maybe someone in here might have a clue. Please be gentle as I am not a programmer.

    - Problem with AddNew row in DataGridView I created a custom class that implements IBindingList. I've tested the class and all properties and methods function as I expect. When I assign an object (of my IBindingList class) to the DataSource property of a DataGridView, everything appears to work fine. Records appear appropriately. I'm able to add a new record, edit an existing, and delete and existing all fine. However, if I enter the last row (AddNew row), exit the row (without making any edits), and re-enter the last row (AddNew row), then I get an error in my code stating that "Operation is not valid due to the current state of the object." I also notice that when I enter the last row, a new row is added to my underlying collection, but when I exit the row (without making any edits) then the row is not removed even though it does not appear in the DataGridView. How do I get the DataGridView to notify my IBindingList class that the new row has been canceled? I posted to this newsgroup, because I didn't feel this was related to a specific language. However, if there is a more appropriate newsgroup for this discussion, please let me know. For what it's worth, I'm working with a VB.NET application, using the v2.0 frameworks and Visual Studio 2005. Tag: POS printer on LPT ready ?? Tag: 139125

    - Alternate Function for CreateFile on .NET Framework,... Hi all, sorry for Crossposting, but i dont know whether someone can help me here. If i remember right, there was a Class or a Member function in the .NET Framework that could do mostly the same as CreateFile can do for me, but i cant remember its Name. By saying the "same" i mean i was able to use it to open Handles to Devices and anything that could be opened with CreateFile and had a Symbolic Name that has been exported from Kernel to User-Space. But i cant remember the class/member name. I am sure there was something inside the .NET FW and natively supported by the .NET. AFAIK it was also something MS used internally in its base classes, but it was exposed to any programmer and was public/static or whatever available from the CLR/.NET. I really cant remember its name, but i used something in the past years ago for opening something, if i remember right to a drive. I think i used it the first time with .NET 2.0... Anybody can help me here, or am i remembering something wrong?

    - WebService and timeout Hi. I'm dealing with scenario when call to any web method ends up with timeout and I try to add the user a chance to retry (wait a little bit) My service proxy code looks like this: AsyncCallback cb = new AsyncCallback(ServiceCallback); IAsyncResult result1 = BeginInvoke(methodName, parameters, cb, this); if(result1.IsCompleted == false) { while(true) { bTO = result1.AsyncWaitHandle.WaitOne(Timeout, true); if(bTO == false)//time out occured { //display window and ask the user to wait a moment, user press OK when it sure that web method finished } if(result1.IsCompleted) break; } object[] ret = EndInvoke(result1);// error every time when time out occured (bTO = false) } My scenario is following: 1. BeginInvoke initialize asynch web method call 2. WaitOne waits for Timeout miliseconds 3. WaitOne returns false because timeout occured, and wait screen is displayed. When user close it the web methos is finished. 4. result1.IsCompleted is true so I expect that EndInvoke shall return the results but it throws excpetion "timeout" !!!. Why? Everything works fine if timeout doesn't occure. Thanks for any advise Shark Tag: POS printer on LPT ready ?? Tag: 139108

    - ClickOnce deployment to Vista 64 bit problems Hello Folks, Has anyone had any experience deploying to Vista 64 bit OS using ClickOnce?

The application in question has Crystal Reports Basic for Visual Studio (x86,x64) selected as a prerequisite. The machines in question have Crystal Reports Basic for Visual Studio (x64) installed and working OK. The first problem we encounter is that ClickOnce does not recognise the existing installation and attempts to install the Crystal Reports Basic runtime again. Then to make matters worse the installation fails with this message" Component Crystal Reports Basic for Visual Studio 2008 (x86, x64) has failed to install with the following error message: "Fatal error during installation. The following components failed to install: - Crystal Reports Basic for Visual Studio 2008 (x86, x64) See the setup log file located at 'C:\Users\martinh\AppData\Local\Temp\VSDB500.tmp\install.log' for more information.

We need to integrate the functionality of the command line "route.exe" utility to create a static route. I would appreciate any pointers to understanding how to do this with the .net framework classes. Thank you, Sid. Tag: POS printer on LPT ready ?? Tag: 139086

    - Funky Build Shows No Errors When Compiling Something got funky with my build. I had been happily developing my web site when all of a sudden F6 (or rebuild solution) decided it was not going to compile my .aspx.cs nor ascx.cs code and thus I do not get error messages until I try to open page in browser. Could someone walk me through how I get this functionality back. In property pages I have "Build Web site as part of soution" checked but does not seem to do anything. Sometimes if I right click on the web site project and select "Build web site" the first time i will get no errors in the error list and the second time I will get errors. This behaviour seemed to rear its ugly head rather unexpectedly. Not sure what I toggled, if anything, that invoked this (ahem) feature. Needless to say I am having another one of those Microsoft moments of which I am sure Bill Gates has needed to hire himself an army of psychic defense artists to repel the curses sent to him daily.

    - XML Comments and back ticks I am curious. When looking at the XML comments provided by .NET 2.0. What is the difference between a single and double back tick? MS documentation http://msdn2.microsoft.com/en-us/library/fsbx0t7x(VS.80).aspx states; For generic types, the name of the type will be followed by a back tick and then a number that indicates the number of generic type parameters. But they fail to mention the double back tick. *Samples from mscorlib.xml* <member name="M:System.Array.AsReadOnly``1(``0[])"> <member name="M:System.Collections.ObjectModel.KeyedCollection`2.ChangeItemKey(`1,`0)"> Tag: POS printer on LPT ready ??

    - System.Diagnostics.StackTrace Hi, How do i get the line number of the calling method in debug-mode. This is what i do: StackTrace st = new StackTrace(); string s = string.Format("Method:{0}, line:{1}", st.GetFrame(1).GetMethod(), "??"); This method gets the callers function name, but i don't know how to get the line number. Is it possible to get the same line number as shown in Visual Studio ?? Thank you in advance. BR Peter Tag: POS printer on LPT ready ?? Tag: 139077

    - assembly always gets built optimized Hi Robert, I recently came across the same problem. I am not able to debug parts of the code when I attach my visual studio debugger to an already launched process. Did you find a way to get across it ? Do I need to modify the build settings for the particular assembly to solve the problem ? Thanks and Regards, Kousik ----------------- 03-Apr-07 02:30:25 I did not mention an important detail (since I didn't think that it matters). I attach to the process that references my assembly after the process is started. When I do not attach visual studio to the process but instead start the process directly from vs by hitting F5 I infact am able to debug. Also note that the probelm with "Cannot evaluate expression because the code of the current method is optimized." only happens with the one project. The sourcecode of all other projects in the same solution can be debugged just fine no matter if I attach later or start the process with F5. What does this hint? How could I narrow the source of this evil down? Does it have to do something with the visual studio hosting process (wich only is used when starting the process with F5) ? Or could it have to do with the working folder or the loaded symbols? ---------------- Tag: POS printer on LPT ready ?? Tag: 139071

    - click once command line parameters how to ? I want to pass parameters to a click once application run from the windows scheduler. I have found several references that tell me these applications are launced using a URL to the deployment manifest using query string parameter syntax: http://mydeploymentserver/MyApplicationFolder/MyApplication.application?param1=foo&param2=bar 2. The question is how can I do that? Is there a way to do this from a .bat file? Do I need to write an application to send the http request? Is there an example application somewhere? This seems like something that is common enough I should not have to write code to get it done. I have found several examples of how to retrieve this data within my click once applicaton but none on how to send the request. Thanks for any ideas. Have a great week-end.

    - ClickOnce exception in IE Our app uses the following chain of urls: 1. yoursite.com/launch.php?room=00000271 - validates the roomid appends an appropriate server variable and encrypts and adds a hash and sends on to #2 2. mysite.com/launch.php decodes the encryption and compares hash for alteration. Re-encodes and redirects to #3 3. clickonceinstaller.application All redirects are done with: header("Cache-Control: no-cache"); header("Pragma: no-cache"); header('Location: ' . $url); If I open IE and type in the starting link I get the clickonce app with no problems. If I leave the browser open and do it again (type in the url) I get: Cannot continue. The application is improperly formatted. Details reveal: the manifest may not be valid or the file could not be opened. + There are multiple root elements. Line 1, position 122. And I notice that I get a HTTP response of 206 instead of 200.

    - IsDnsEnabled We just moved to .NET 2.0, and in trying out System.Net.NetworkInformation and friends, I find that it always says IsDnsEnabled=false, even when that connection clearly is using DNS to resolve names, I can fetch back DNS server addresses, etc. Anyone else see this? All of the other settings look correct. I was also *very* disappointed to find that NetworkInformation only gave read access to network settings. To make changes I have to continue using that abominable WMI. Which causes me even more grief by behaving differently on Win2K than on XP. Is there any chance that there is something for this in 2.0 and I'm just missing it? (Yeah, I know, "Welcome to 3 years ago". Hey, large companies move slowly.) Tag: POS printer on LPT ready ??

    - SingleInstanceApplication gets SocketException on Vista with .NET I have a single instance C# application I wrote in VS2005. When I update that to VS2008, I get a SocketException in the first instance, when the second tries to run. I made a very simple test using VB. In VS2005, make a VB win app. In the project properties, check the "Make single instance application" box. Run the app in the debugger. Launch a second instance from File Explorer. It will, correctly, startup briefly then close. The first instance will bring itself to the forefront. This is good. When I convert the app to VS2008 and run the app in the debugger, launch a second instance, the first instance will get a First Chance SockedException then an IOException (wrapping the SocketEx) in the debug output window. The exception is handled, but I'm wondering if I need to be doing some different setup or permissions something. I'm running this on Vista. I get the exception running normally, running as administrator and running with UAC off. When I do this test on XP, I do not get this exception. Is this something I need to be concerned about in my code? Is this a bug with the framework/Vista that needs to be reported? Thanks, Tag: POS printer on LPT ready ?? Tag: 139050

    - CodeBase and Dependent Assemblies Hi I have a question or two which I'm pretty sure of the answers, but wanted it confirmed by those who know more than me!! Basically we want to share assemblies across many applications and allow for side by side execution, but for reasons that I donâ??t quite agree with the GAC is ruled out! These applications are essentially scheduled tasks hence using the GAC means deploying to many boxes. So that leaves me with adding a CodeBase element for each dependent assembly. This works fine except when the referenced assembly also depends on another assembly in the CodeBase directory, in this case the application fails with a FileNotFoundException. Using FusLogVw it's clear that the CodeBase is not used when probing for this dependent assembly that is not directly referenced by the application. If I add another dependentAssembly element for this assembly then all is good. So at last I get to my questions: When loading an assembly via a CodeBase why doesn't Fusion use the CodeBase to find any of its dependent assemblies? Other than the GAC is there an alternative? Thanks for your help. Cheers Doug Tag: POS printer on LPT ready ?? Tag: 139018

    - VLAN, Socket and network configuration In our company we have touchscreen in appartment in a building. We want to 'secure' the touchscreen from each other, and we set each of them in a VLAN. Now we have security cameras and intercom (on other VLAN) and we need to share them across the appartment, for that we have a firewall whic does routing as well. Also I'm new to this company and I don't really understand very well how all of this work. Currently it's all TclTk and Linux. We are going (thanks to my evangelism) to .NET/WPF (and probably Windows Server as well). Now I wonder about: 1. how do I write a program on the intercom machine which access the flat? (they are on different VLAN and there is some tagging of the network packet going on as far as I understood) 2. what do you think of that architecture? it's just that VLAN are mysterious to me and I wonder why not having all the machines on the same network? Yet I'm sure with a bit of explanation it will all become clear,any MS link on the topic? andadvice about the config? 3. Also does Windows server could act as a router for this kind of configuration?

    - Windows Service & System.Timers.Timer production issue... I'm looking into a production issue related to a windows service and System.Timers.Timer. The background is the windows service uses a System.Timers.Timer to periodically poll a directory location on a network for files and then copies these files to another location (on the network) AND then updates a record in the database. The file copying is performed before the database update because the file system is not transactional. The code C# .Net (2.0) has the required try/catch/finally to capture any exception that might be generated during the Timer Elapsed event - any errors that are generated are logged. I also know about the issue relating to System.Timers.Timer swallowing unhandled exceptions. The code also logic (locks) to prevent to Timer Elapsed event being processed at the same time, the files are processed in a synchronous manner. The issue that is arising is intermittently files are being copied BUT the database record is not being updated as expected AND there is no error message in our logs. As I said this is an intermittent fault that I can't reproduce on the development server even when I chuck a large number of files (large file size as well) at it. I want to know has anyone had any similar experiences. Next step is to investigate the hardware & software configuration of the production server. Cheers Ollie Riches Tag: POS printer on LPT ready ??

Hi

What do you mean with ready?

You could send a zero byte printjob to the printer and after a slight delay
test if the print queue is empty.

This code I'm using to find out is POS printer on COM port is ready for
printing:

Dim oSerPort As System.IO.Ports.SerialPort
oSerPort = New System.IO.Ports.SerialPort(cPort, 9600, Ports.Parity.None, 8,
Ports.StopBits.One)
oSerPort.Open()
If oSerPort.DsrHolding Then
'Printer is ready
Else
'Printer is NOT ready

If LPT1 is an internal parallel port, not a USB connected device, then you
can use IONet.dll from my homepage to examine the printer status register.
