 - TraceSwitch XML file error I am working through the Windows Applications with C# book by Amit Khalani for the 70-316 exam, I am using VStudio version 7.1.3088. In the chapter on Testing and Debugging there is an example where you are asked to do as follows..... "In Solution Explorer, select View All Files from the toolbar. Navigate to the bin\debug folder. Right-click and Add New Item. Choose to create an XML file and name the file StepByStep12_3.exe.config". You then add some xml code to specify a trace switch. The rest of the project is a basic Form with code that aims to demonstrate various levels of output from the TraceSwitch class by changing the value of the switch that was set in the XML file above. The following variable is declared in the Form... static TraceSwitch traceSwitch = new TraceSwitch("FactorialTrace", "Trace the factorial application"); I managed to do add the xml file to the debug folder after figuring out that you have to choose to select 'Include in the Project' for these normally hidden folders to be available in the IDE. However when I Build the project the new XML file is deleted and therefore the switch value is not picked up. Has anyone come across this behaviour? Maybe there has been a change since the book was written. I have downloaded the errata for the book from the Que website and there is nothing about this chapter being wrong.

 - Array of value-types Another question, related to my previous post: Is array of value types a value type or a reference type? From what I know it is a reference type in normal usage in .Net 1.0 and 1.1. Do you know of any case where it would become a value type? Maybe in .Net 2.0?

 - Struct with fixed-length array member - is it possible? Hello, Can you provide some hints on how would you solve a problem like this? I'm out of ideas... Here's the problem: Let's imagine a C structure containing a fixed-size array struct XYZ { int V1; int V2; double V3[50]; }; This structure, when allocated, occupies a contiguous block of memory (408 bytes in my compiler). Now I would like to have the same structure in C#, such that it would have THE SAME MEMORY LAYOUT as the C structure. The memory size does not need to be identical as in C, but the structure should occupy a single memory block and all data, including the array, should be placed in this block. There is no possibility in C# to declare a fixed-size array and to 'embed' it completely in a struct. When I make a declaration like this: public struct XYZ { int V1; int V2; double[] V3; } the V3 member is a reference to array object, not the array itself. Can you think of any way to get the C/C++ layout? Best Regards, Rafal Gwizdala Tag: Serialization of enums Tag: 95184

 - Reflection GetObjectByStringReference(string) as object Hi I am searching for a method like this GetObjectByStringReference(ObjectName as string) as object E.g. Dim var1 as string = "Test" Dim O as object = GetObjectByStringReference("var1") Console.writeline("Value of O:" & O.ToString()) Should Output Test I need this to get detailed error logging information from my methods. I can get the Argument names my this code Dim _methodif As Reflection.MethodInfo = Reflection.MethodInfo.GetCurrentMethod Dim _param() As Reflection.ParameterInfo = _methodif.GetParameters() For Each _pi As ParameterInfo In _param MessageBox.Show(_pi.Name) Next What I need is to get the object reference of a variable by the name of the variable.

 - Databinding w/Update Hi All, I am under the impression that databinding allows a control to be updated automatically by the interface when the underlying value changes. However, many of my controls will not update after the initial display. If I have a boolean property and I bind it to a checkbox's checked property, I should be able to change the boolean from true to false and observe the checkbox go from checked to unchecked. Is there something else I should be doing or am I totally off-base? -- Thanks, Harry Tag: Serialization of enums Tag: 95172

 - Using XMLDocument.Load with a memory stream... I am looking for examples that would illustrate something similar to the following requirements: I am building an in-memory xml structure using the following as the setup and classes to perform this step: If fileOutput Then Dim XmlWriter As New XmlTextWriter("D:\QICS_MT\Debug Output\" & _ fileName, System.Text.Encoding.UTF8) XmlWriterXsdMultiLevel(regexObject, _ elementCollection, _ XmlWriter) Else Dim coreStream As New MemoryStream Dim XmlStreamWriter As New StreamWriter(coreStream,Text.Encoding.UTF8) Dim XmlWriter As New XmlTextWriter(XmlStreamWriter) XmlWriterXsdMultiLevel(regexObject, elementCollection, XmlWriter) End If If I take the upper branch I can successfully create and write the document and subsequently I can open the resulting Xml file and validate it against an external xsd file. I would like to be able to take the lower branch and create the same xml structure, yet in this instance I would like to be able to pass the created xml content to an XmDocument class, so that I can pass and use it elsewhere in the application. I am having problems understanding how to use the XmlDocument.Load(Stream) method, though I believe this is how I should do this. I have not found many examples of using this method, so I was looking for assistance in that area. Thanks, Tim Tag: Serialization of enums Tag: 95168

 - Match Blank Characters outside Multiline Comments Hi, all, I'm now writing a program to compress JavaScript code. One puzzle is how to write a regular expression to find out and remove all the redundent blank spaces. However, those blank spaces that are in the comments should be kept intact. I've tried to write some Regexs, and I list them here for your information: regex = new Regex(@"/\*[\s\S]*?\*/"); // pattern used to match a multiline comment block regex = new Regex(@"//[^@\n]*\n"); // pattern used to match a single-line comment regex = new Regex(@"(?<!(?://[^\n]*))\s+"); // pattern used to match blank characters outside single-line comments Now the problem is how to match all the continuous blank characters outside multiline comments? I tried the following Regex: regex = new Regex(@"(?<!(?:/\*[\s\S]*))\s+"); but this does not work, and will lead to a CPU dead-loop with no reactions for a long time. I'm a newbie in Regular Expression. Can sombody help me? Thanks a lot! Best regards, Laser Lu Tag: Serialization of enums Tag: 95162

 - Error When Interop'ing to COM+ Managed Object with Library Activation I have a remoting server that is on the same local box as a COM+ managed object with Library Activation. When I try to activate the object from the remoted assembly, I get the following error: "The specified activation could not occur in the client context as specified."

 - HttpWebRequest & SSL problems I have a HttpWebRequest connecting to a SSL server. The server has a valid Verisign certifcate installed, so no client-side cert is needed. I am getting intermittent errors when connecting to the server. One in every five times I try to connect, I see the error: "The underlying connection was closed: Could not establish secure channel for SSL/TLS.)" I tried using a ICertificatePolicy to allow any certificate, but that didn't work. The funny thing is when I load my own certificate using: request.ClientCertificates.Add(X509Certificate.CreateFromCertFile("mycert.cer")); ...I never see the error. However, I don't want to ship the app with a client cert. Suggestions? Tag: Serialization of enums Tag: 95149

 - String.Empty vs. string literal Anybody have a definitive, backable answer to which version performs better: String.Empty vs. ""? Given: private void TestEmptyObject ( string value ) { int nCt = 0; if (value == String.Empty) ++nCt; } My experiments show that they are equivalent except for String.Empty is loaded through ldsfld and "" is loaded through ldstr. They both eventually call String.Equality(string, string) which will treat them the same. My rule is to use "" because to me it is clearer to read. Anybody have a really good reason why String.Empty should be used instead? Of course I'm only talking about a single language here. Understandably String.Empty is useful when trying to represent an empty string in a (programming) language neutral way but this is rare.

 - String Concat vs. Plus operator Does anybody have a definitive, backable answer to which way is better when concating strings (String.Concat vs. +). You can easily prove one faster than the other in contrived examples. I'm interested in real-world examples. My experiments have shown that both versions are equivalent. Given: void TestStringOp ( string value1, string value2, string value3 ) { string result = value1 + " " + value2 + " and " + value1 + " " + value3; } void TestStringConcat ( string value1, string value2, string value3 ) { string result = String.Concat(value1, " ", value2, " and ", value1, " ", value3); } Dumping the IL for TestStringOp reveals that this is converted to the equivalent of this: string[] temp = new string[] { value1, " ", value2, " and ", value1, " ", value3 }; string result = String.Concat(temp); Dumping the IL for TestStringConcat reveals that the exact same code is generated. Therefore the performance is identical. The bad thing about this is that internally String.Concat will allocate another string array and copy the strings into it before finally calling the fast string allocator. The only time I think Concat is a better choice is when the # of strings to concat is 4 or less. In this case the optimized version of the concat routine is called. Therefore my running rule is that if concatenating 4 or less strings then use String.Concat otherwise it doesn't matter. Understandably timing this code won't be very revealing since the optimizer will probably get rid of all the code anyway but by comparing the IL I should be able to overlook the optimizations that will be done. Anybody have definitive, backable answers to this? Thanks, Michael Taylor - 4/18/05 Tag: Serialization of enums Tag: 95140

 - Changed functionality in system.directoryservices ver. 1.1.4322.20 Dear all, we have the following problem. We like to update a LDAP diretory using system.directoryservices. This worked fine in the past but now it stopped working, we get a System.NotSupportedException. We use the following syntax: <DirectoryEntry>.Properties[<attribute>][0] = <value>; Further research turned out that this does work using system.directoryservices.dll 1.1.4322.573 but doesn't work using version 1.1.4322.2032. To investigate the difference I used Reflector (c# disassembler). I found the following code (for set_item) in version 1.1.4322.2032: if (this.needNewBehavior && !this.allowMultipleChange) { throw new NotSupportedException(); } base.List[index] = value; Version 1.1.4322.573 doesn't has this "if" criteria, it simply sets the value. If I look at the values using the debugger I see that this.allowMultipleChange is false and needNewBehavior is true, therefore I get a NotSupportedException(). So now I have a huge problem: I can't update my LDAP anymore. Can anybody help me with this problem? Or does anybody know where I can find documentation about the differences in the different releases of a dll? Or does anybody know where I can find system.directoryservices newsgroups? Or does anybody know how to contact miscrosoft about this matter (somebody must have changed the code for some reason without documenting it)? Thanks, RenÃ© Tag: Serialization of enums Tag: 95131

 - Code isolation with the AppDomain class I am responsible for the plugin-loading part of an app. One of the things the loader has to do is check licensing, and unload any unlicensed plugins. I naively did this as: AppDomain Sandbox = AppDomain.CreateDomain("Sandbox"); try { Assembly Suspect = Sandbox.Load(PluginName); // do some tests on Suspect.GetExportedTypes() } finally { AppDomain.Unload(Sandbox); } The code seemed to work, but it turns out that Sandbox.Load(PluginName) is actually loading the PluginName into both the Sandbox AppDomain and the default AppDomain. When I unload Sandbox, I'm left with all tested plugins still loaded into the default AppDomain, whether they are licensed or not. I do NOT want to execute any assemblies: I just want to load my suspects; do some tests in the temp AppDomain; and return the test results to the default AppDomain. It looks like my only option is to use AppDomain.DoCallBack to execute my tests, and use SetData to store the results.

 - Updating Service Installers This is a question from the automated practice test that comes with the Micrsoft MCSD boxed set of books. I think it's wrong. You create a Windows Service that connects to a SQL Server data source when a user logs on. You find that because of network problems the client application disconnects from the data source. You need to change the Windows Service so that it checks the connection every five minutes and reconnects to the data source if the connection is broken. You need to add this functionality to the Windows Service, so you uninstall the service add the functionality. You then rebuild and reinstall the service. However, when you run the service, you cannot see the newly added functionality. Which of the following tasks should you perform to view the new functionality? (Choose one correct option.) 1) Update the existing installers, and then rebuild the service application. 2) Debug the service, and find out why you cannot view the functionality. 3) Remove the existing installers, add new installers, and then rebuild the service aplication. 4) Verify the permissions for the security context, and then rebuild the service application. Answer: 3 (???) What does removing the installers do? If you look at the code in the studio-generated installers, it just consists of basic properties like the service name and the account. Why would removing the installers and adding identical installers have any impact at all? Tag: Serialization of enums Tag: 95072

 - .NET SP1 messed up... Hi... I recently installed .NET1.1 SP1 from the windows update website (this cannot be uninstalled). Also installed MS Installer 3.1, which I uninstalled now, after facing problems in VStudio. This is what happened: I had a solution with several projects and a setup project. After installing .NET1.1 SP1, whenever I start to 'Build' the setup project, it stops after the first line: ------ Starting pre-build validation for project 'Setup' ------ ------ Pre-build validation for project 'Setup' completed ------ ------ Build started: Project: Setup, Configuration: Debug ------ Building file 'C:\...\Visual Studio Projects\Project1\Setup\Debug\Setup.msi'... Then MSIEXEC.EXE shows up in the task manager process list - It now comes up with a dialog saying it is looking for VS .NET 2003 installation vs_setup.msi file. I have to cancel out of this dialog so the 'Build' can proceed. However, this problem remains even after I uninstalled MS Installer 3.1. So something must be wrong with SP1. Anybody knows about any problems with .NET1.1 SP1? Is there a fix for this? Can I get rid of SP1 if I reinstall .NET1.1? TIA Dumbo DotNet Tag: Serialization of enums Tag: 95063

Create a new C# (Probably the same in VB dotNET but I've not tried it) Windows application with 2 forms, the default form -Form1 and one other one. that has a bunch of controls on it (say 20 buttons, 20 labels and a DataGrid) - Form2. On the default form, add a button to display the second form with some code like: private void button1_Click(object sender, System.EventArgs e) { using (form2 formTwo = new form2()) { form2.ShowDialog(); } } also on Form1 add a label, and a timer that updates the label text as follows (updates every 5 seconds -Interval = 5000-): private void timer1_Tick(object sender, System.EventArgs e) { label1.Text = GC.GetTotalMemory(False); } and finally a button that forces a Garbage Collection: private button2_Click(object sender, System.EventArgs e) { GC.Collect(); } OK, my question/query is this, if I repeatedly click the button to open the second form, then close the second form, click the button, close the form etc. about 20-30 times, the display of GetTotalMemory seems to keep going up, and even after forcing Garbage Collections, never seems to get fully reclaimed. Should I care? and if I should, what (if anything) can I do about it? I would really appreciate an answer from someone who understands these things... Thanks a lot, Chris.

 - Start Up Hi, Im not sure if im posting in the right place , here is the problem , I have some code (written in .net) that is started up when the PC starts and runs forms full screen with no borders. The problem is that, the program is hooked up to a wireless network to the server, but if my program is loaded at startup the wifi network doesnt connect, meaning that the program cant get access to the server. If the program is taken out of startup and loaded manually, the wireless network has enough time to connect and everyhting is fine. What im hoping is that there is some way of delaying the load on startup or any other work around for this Thanks Tag: Serialization of enums Tag: 95037

 - Transpose Dataset? Hi, I have an aspx page that queries and displays data from an Excel file. However, the entries inside this Excel file are in columns instead of rows. Is there anyway I can "transpose" the dataset with ASP.Net? I know I can transpose the Excel file before uploading it, but I'd just like to find out if it can be done in ASP.Net. Thank you.

 - Is there a max limit on the number of Managed Windows Services that can be run on Win 2000 server? We have a situation where we keep hitting below error 1053 The .......... service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. whenever we try to start managed windows service above a specific number. On one server (SERVER1) it is 25, on another (SERVER2) it is 27. There are 9 different services, each 9 constitutes a release version. Were are trying to use the same server to handle multiple versions, however, we have this limitation where we can only get a max of 3 sites (3 x 9services) at best running. It does not matter which services are running, when we reach this limit no other managed service will start. If I stop one, I can start another. I don't believe it is a licensing issue, we do use Crystal however, the same issue occurs if I do not start those services that use the Crystal dll's. The environment is Windows 2000 server. Framework is 1.0. Any help on this is much appreciated. Rgds Yucel Tag: Serialization of enums Tag: 95025

 - Custom counters file view is out of memory. We are using Microsoft's Enterprise Instrumentation Framework. The TraceSessions.config file just started logging this error in the Application Log when it gets saved. It didn't do this until about two days ago. Unable to read and validate the configuration file C:\Inginix\Logs\TraceSessions.config. The following errors were returned: Custom counters file view is out of memory. Can someone explain to me what this is and how to fix it? I can post the file if that would help. Thanks, John Tag: Serialization of enums Tag: 95019

 - Help with Addin I am trying to create an addin that will loop through all my projects in a solution and all the forms with in a project to set a form property. How can I test the project item to see if it is a form? foreach (ProjectItem p in theProject.ProjectItems) { System.Diagnostics.Trace.WriteLine("ProjectItem = " + p.Name); // Check to see if its a c# file Is there a better way if (p.Name.Substring(p.Name.Length - 3, 3) == ".cs") { } } Tag: Serialization of enums Tag: 95016

Is the enum embedded in the class or outside in the namespace (same file,
not in the class)?
