    - Read File Fast Hi, Which one is the fast way to open a file and read it. If possible without buffers and any other kind of conversion. I need one step from the harddisk to the Array. Right now I am using FileStream. Is this the best way? Thank you, Roby Eisenbraun Martins Tag: FileStream.Read method Tag: 97533

    - designers? I am getting this exception A first chance exception of type 'System.ComponentModel.Design.Serialization.CodeDomSerializerException' occurred in system.design.dll Additional information: The variable 'treeView1' is either undeclared or was never assigned. I am trying to call Deserialize on ((System.ComponentModel.Design.Serialization.RootCodeDomSerializer)(rootSeri alizer)) and that fails with internal exceptions on some of components (tree view and group box) which I placed on Panel.

    - FileSystemWatcher not firing events if Path is an empty string Dear All, In my C# application using .NET 1.1 I am trying to watch for file and directory events using FileSystemWatcher. Things are working as expected if I watch a specific directory. However I need to watch all folders on the local computer and I understood MSDN documentation that I can achieve it by setting FileSystemWatcher.Path to an empty string. I also set FileSystemWatcher.IncludeSubdirectories to true. However with this combination of properties FileSystemWatcher does not seem to fire any Created/Deleted/Renamed events on XP SP2. Am I doing something wrong? Thanks, - LR Tag: FileStream.Read method Tag: 97521

    - How to do simple memcpy in C#? Hi, I am very new to C#? How could I do a simple memcpy (in C/C++) in C#? Example; I have a Byte[] Data = new Byte[500]; And I want to copy various things like int32, other bytes etc into various section of the Data[]. How do I do that? With C/C++ is rather simple, which is memcpy( ). Thanks for readings and hope for some advices. Tag: FileStream.Read method Tag: 97514

    - Text Files, Encoding and NewLine character hi, I'm creating a component to read text files. I'm using TextReader with Encoding Text component, because there are several different types of text files and the encoding component translates the bytes from this file to the correct characters. To which one of this text file's types almost all the time '\r\n' is the new line character. But sometimes it could not be, that's why I'm using NewLine property to know exactly who the next line characters are in which case. At that point all work's fine with TextWrite, but hell knows why TextReader doesn't have a NewLine property. Is there any way to identify the NewLine character of a determinate Encode system? or just stop using the NewLine and work only with '\r\n'? Another question, TextReader copies all file from the harddisk as soon as it is initiated, or it copies part of the file when I'm using Read();?

    - A challenge to all MVP's.......GET A J.O.B. for once in your life You guys who hang around here are some of the sorriest and most incompetent programmers( if you can even be called that) ever!!! The only thing you know are reference books and theory that's been proven wrong in the real world You sit in front of your computer answering the SAME nickel and dime questions day after day, week after week, year after year so you can't possibly have any real experience in making an actual program and all you do is give BAD advice to those seeking it here. As far as I am concerned, Microsoft should end the MVP program as all that it fosters is wanna be programmers who only give bad advice and never DO as they ADVISE. You have essentially ZERO experience in coding .NET to begin with. DEAR MICROSOFT: Kill off the MVP program. It only fosters people who strive for publicity in trying to get a programming job as opposed to being actually able to do the job. The MVP's only make programmers and the software industry look bad as a whole as these people are supposed to be MOST VALUEABLE....when in they in fact are the MOST WORTHLESS programmers ever, especially when they actually do get a job they only sit around with theory, and all that nonsense of architecture and best practices only to not even deliver the project to begin with. Why not put all that theory and knowledge to the test and actually see if it really works? Ha ha ha..like you can even do that? All these people do is get silly certification and they STILL CANNOT GET A JOB!!! Much less actually do the job.....Imagine that!!! It's no wonder companies go off shore, as the quality of software sucks anyway, so why pay extra in the US when it's going to be late, buggy and not what the customer wanted anyway. MESSAGE TO MVP's: WAKE UP!!! START DOING SOME REAL WORK or someone will make sure the world knows how incompetent you MVP's are and if you think you will have a hard time now flashing your MVP and Certification letters around, wait till they know the real truth about you and will think twice about even mentioning you have a certification or MVP status......and no talking in front of user groups don't count as most those groups are also like you, unemployed, can't get the job done right.

    - Strange Excel importing problem I have a routine that imports a list of part numbers into a dataview: strExcel = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & boxFile.Text & ";Extended Properties=""Excel 8.0;HDR=NO""" cnnExcel = New OleDbConnection(strExcel) da = New OleDbDataAdapter("Select * from [ODRJYUFI$]", cnnExcel) da.Fill(ds, "Excel") dv = New DataView(ds.Tables("Excel")) This works fine exept when the following condition happens: The part numbers are alpha-numeric. When a numeric only part number (mixed in with alpha's) is read in, NULL is stored. The routine will read in numeric values ONLY when all the part numbers in the spreadsheet are numeric. I've tried formatting the column in the spreadsheet as Text to try and trick the routine, with no luck. Any suggestions? Thanks Tag: FileStream.Read method Tag: 97460

    - Parameter Methods Performance (val,ref,out) Hi, I would like to know which one of the following parameter types is faster. I think is ref because sending a pointer to a class seems to be much more faster then copy all the class at once in the method call. But when I was having classes about C# programming in Microsoft Official Course, my teacher told me that in .NET val is faster, that's why it is the default parameter type. But he couldn't explain why. Any ideas? Thank you. Roby Eisenbraun Martins Tag: FileStream.Read method Tag: 97441

    - Checking for implementation of an interface I have an application that accepts plugins. It allows the user to choose which plugins they want to run from a list of available plugins. My problem is that I need to build that list of plugins by checking the assemblies in the plugins folder to see if they implement the plugin interface. If I load each assembly and check it, then I have all those assemblies in memory until the application gets shutdown, even though the user may only want to use a few of them. My idea was to load them all into a separate appdomain to check them and build my list, and then unload that domain. Then I could just load the plugins that the user chooses. My problem is that I don't know how to check the assembly to see if it implements the plugin interface once its loaded into the separate appdomain. Can anyone point me to an article on this, or some sample code? Thanks! Tag: FileStream.Read method Tag: 97414

    - EnvDTE and EnvDTE80 I am using Visual Basic Express (May release) and I am trying to create a solution programatically. How do I do this? I know I need to use the AddFromTemplate but how do I determine the path to the template that I want to use, let's say the template is the "winfxapplication" template, which on my machine is "C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\VBExpress\ProjectTemplatesCache\1033\WindowsApplication.zip\windowsapplication.vstemplate" Or do I point it at the .vbproj file: "C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\VBExpress\ProjectTemplatesCache\1033\WindowsApplication.zip\windowsapplication.vbproj" I'm assuming there are just a few lines of code required. First of all, I want to create a VS2005 object. I have tried: Dim env As EnvDTE80.DTE2 = CType(Microsoft.VisualBasic.Interaction.CreateObject("VisualStudio.DTE.8.0", ""), EnvDTE80.DTE2) but that tells me it cannot create the ActiveX object. I then tried: Dim env As EnvDTE.DTE = CType(Microsoft.VisualBasic.Interaction.CreateObject("VisualStudio.DTE.7.1", ""), EnvDTE.DTE) and that creates the object, so when I do this: ENV.Solution.ADDFromTemplate("C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\VBExpress\ProjectTemplatesCache\1033\WinFXApplication.zip\WinFXApplication.vbproj", "e:\mytests", "myproject.vbproj") I get the message "The file blah blah is not a valid project file. The project file is missing the 'VisualStudioProject' section." whatever that means. I think I am on the right track here, can anybody out there just straighten me out on this? I am starting to tear my hair out. Thanks in advance, Richard Tag: FileStream.Read method Tag: 97413

    - Protecting classes with LicenseManager: COM issue Hello, I have a class (C#) in an assembly that I wish to protect with a licensing scheme. The class is designed to be consumed by any other managed code language, and via COM clients. That is, the class is registered for COM interop, and may be instantiated by VBS code, etc. We are using the inherent .NET Framework licensing classes. We've used the LicenseProviderAttribute to specify a LicenseProvider descendent. The LicenseProvider descendent's GetLicense() method checks the LicenseContext for LicenseUsageMode.Runtime or LicenseUsageMode.DesignTime. This works great when the class is being instantiated by a .NET application. We run into a problem when the class is instantiated via COM interop from, say, a VBS script. When started this way, the GetLicense() method LicenseContext argument is _always_ LicenseUsageMode.DesignTime. This upsets the licensing model we want to use. Is this working as designed? I had hoped a class instantiated via COM interop would be seen to be working in LicenseUsageMode.Runtime mode, not LicenseUsageMode.DesignTime. Thanks in advance, Grant Tag: FileStream.Read method Tag: 97411

    - "scrolling buttons" I would like to make some kind of buttons that can be used to scroll other things. Actually it would like it to be exactly as in Lightwave's Envelope Editor - when you push the button, the mouse pointer should disappear and you should be able to scroll something with moving your mouse up/down and left/right. Perphaps hiding mouse wouldn't be that hard [or would it?], but I wonder about "scrolling" itself - I generally use MouseMove event, and in this case the pointer would quickly leave the button's area and i would get no event to handle...

    - 1.1 and 2.0 Can I install the 1.1 framework with the 2.0 framework on the same server and run VS2003 and VS2005 at the same time? I installed 2.0 on a workstation and it looks like the 1.1 framework stayed put. If anyone can clarify this it would be greatly appreciated. Thanks all, Andy Tag: FileStream.Read method Tag: 97388

    - ASP.NET lock up Hi. I'm experiening random lockups of my ASP.NET application. I see lots of these error messages from .NET runtime in the event log: The description for Event ID ( 0 ) in Source ( .NET Runtime ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: .NET Runtime version 1.1.4322.2032- Setup Error: Failed to load resources from resource file Please check your Setup.

    - .Net Framework 2 Beta 2 Hi Can anyone tell me what version of mscorlib is shipped with the .net framework 2 beta 2? On my machine it is 2.0.0.0 and on a colleagues machine it is 2.0.3600.0. Which is the correct version? I am havineg problems loading .net 1.1 assemblies when I have the .net2 framework installed on my machine and it seems to be because mscorlib is taking into account the "processarchitecture" attribute when creating the reference identity and comparing it with the definition identity which does not have the "processarchitecture" attribute, so it says the referenced file cannot be located. My colleague does not seem to have this issue, but his mscorlib version is 2.0.3600.0 and mine is 2.0.0.0. Regards Tag: FileStream.Read method Tag: 97361

A first chance exception of type 'System.IO.FileNotFoundExceptiÂon' occurred in mscorlib.dll followed by A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll Additional information: Type passed must be an interface. If i restart the machine i will receive the first error again.

I think if there is only one weak point in dotNet performance, it is its slow win forms, which make Win developers like me to deny the full power of .NET. It is not just the load time that teases, we have too much overhead with heavy treeViews and listViews that sometimes make us giving up the whole project on .NET and going back to C++.

    - Exit Code 67 I have a fairly simple Windows Forms application developed using C#. It basically listens to two serial ports and displays the results. There are three threads that each listen to a network socket. Additionally there is the GUI thread, the two serial threads, and some threads to process the data from the serial ports. For the serial communications I am using John Hind's NETSerialComm wrapper library. Occasionally, the tool will exit with error code 67. When you look that up, it is listed as "The network name cannot be found." At the time it happens there are no network connections, just three sockets in listen state. It can happen after 12 hours or 3 days. Or not show up for a while. Any insight into why this might happen is appreciated. Dave Uhrenholdt Tag: FileStream.Read method Tag: 97347

    - problems with Microsoft.Enterprise.Library I am trying to use EnterpriseLibrary packages in an IOC pattern. Note on implementation: I have LoggingServiceManager which is tightly bound to a Logging Application Block and implements an interface ILoggingServiceManager. ILoggingServiceManager is contained within an asssembly CommonServiceManager. My intended user (a class cMain) would refer to the CommonServiceManager and using ILoggingManager interface invoke methods of the Logging Application Block. Issue: The Logging Application Block uses run-time binding and hence needs references of Logging Application Block at the cMain level. And this breaks the IOC pattern completely. Has anyone comeacross such a scenario with Application Blocks. this problem occurs with Logging, Caching and Cryptograpghy Application Blocks (so far...).

Hi,

Do you know how the method FileStream.Read populate the Char array if
we don't use out or ref?

Thank you,

(I assume you either mean a byte array, or you're using managed C++ -
streams don't deal with characters, they deal with bytes.)

Because arrays are reference types. When you pass an array, you're
actually passing a reference to the array. The method call can change
the contents of the array without changing the value of your variable.

See http://www.pobox.com/~skeet/csharp/parameters.html for more
information.
