    - how to make an object readonly in runtime? I have some data in a DataTable object that I'd like to put into a static class for the entire app to use, kind of like a cahced global value. The data in there should not change, but DataTable by default can be changed. Is there an easy way to make it read only. I can probably create my own wrapper class to accomplish this but hopefully there is a way to do this directly on the DataTable. Thanks in advance for any help Bob Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80721

    - Best practice to lock DB SQLServer records in VB.NET application Hi all; I wonder if you have an opinion about this matter: Besides using "Version Number Approach" and "Saving All Values Approach" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskPerformingOptimisticConcurrencyChecking.asp suggested by MS for solving lock problems, is there any other options to do this? In my opinion there's one limitation in these methods: if you loose your connection to your db for some reason while comitting the transaction, how can you be sure the lock is in the rigth state? Can you use threads to lock and unlock records? If so, can someone point me to some kind of a sample or tutorial to learn more about it? Urgent! Thanks in advance!

    - Type.GetType Access is denied Hello, The .NET application I have just installed at a client web site is throwing a strange error. At first the applications works without any problems, but after 10 mins or so Access denied error messages are thrown. The application, web based, late binds to a series of assemblies, none of which are in the GAC. I have configured the application to impersonate the IIS user and have set the user to have access to all relevant directories (wwwroot, wwwroot/bin, Microsoft.Net/framework/v1.1.4322) and disabled the index services service. After digging a little deeper it seems the error is thrown when calling Type.GetType, but like I mentioned earlier everything works fine but then suddenly dies. Can anybody think why this is the case and what I can do to resolve this irritating problem. Thanks Richard. Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80690

    - Microsoft's DNP for Oracle. HELP!! (sorry for the x-post) Hello all, I am currently working on a project that uses MS's .net provider for Oracle. Now, here is where it gets WEIRD!!! for some reason when we run it in VS.NET's IDE it is fine, a previous build deployed (xcopy) onto a test PC is fine. However; when we have recently but a new build on it doesn't work. The only thing (and I ain't buying it) that my work mate says it is down to is that the path of the EXE has brackets in it!!! When we remove the brackets it is fine (something ain't right)!!!! Has anyone had a similar scenario or a explanation for this bizarre behaviour????

My old asp code successfully posted using a form action with fields such as &name="Joe Jackson" in .NET, if I pass this to the requeststream the cgi interprets some extra double quotes &name=""Joe Jackson"" If I leave off the quotes entirely the CGI script fails.

    - Serialized Hashtable Hi I've tried moving a serialized hashtable made in WinXP (std .Net framework), to a PocketPC device (Compact Framework). I've ran in to all kinds of problems, and have not been able to get this to work. The problem is not in the actual filecopy. I've tried the CompactFormatter (http://www.freewebs.com/compactFormatter/) for binary serialization. No luck when deserializing on the device. CF wont deserializa std framework, vice versa. I've tried XML serialization from opennetcf (http://www.opennetcf.org/library/OpenNETCF.Xml.Serialization.html). Got a problem since Hashtable implement IDictionary. For some reason. Is there another way to do this? Is there a reason why this should not work, or is it me who's doing this all wrong. If Hashtable in std framework is differently implemented than the Hashtable in CF, that would explain incompatibility when deserializing. But is that the case?

    - Binary Compatibility equivalent in .NET ? I have a client that insists that there be some sort of binary compatibility equivalent in the .NET assemblies I'm producing (converted from VB6 code). I understand their concern: while you don't *need* binary compatibility since you can just plunk in newer versions of assemblies (unlike in COM where the entire mess had to be recompiled if you didn't use binary compatibility), you might want some way to warn or prevent developers from making changes that may break an app using the assembly. I think this was the other main advantage of binary compatibility - it prevented thoughtless breaking changes thrown in all over the place. Any ideas?

    - FileLen reports wrong file size 1. A function starts an unknown external program. 2. The external program starts writting a file. 3. The function should report the size of the file being written by the external program. How to achieve the 3rd point using .net framework 2003 only? Notes: for a certain external program .Net's FileLen reported file size is allways 0 until the file is closed. Microsoft Scripting Runtime's FileSystemObject.GetFile(FileName).Size retports the correct file size while it is being written. VB Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80650

    - Shared Static Variables in vb.net please? Does anyone know if MS has / is planning to introduce a shared static local variable to VB.net? I have had a few instances now where I thought this would be a tidy way to write some code. i.e. an instance method needs to access a shared (class) variable, and it is the only method that needs to access it. I really like the concept of static variables in vb.net, they make class definitions a lot tidier I think. Just a shame they called the keyword "static" as seems to confuse people. Cheers.

    - Bug in timers.timer ? Hi, Maybe Iâ??m doing something wrong but I canâ??t know what. Iâ??m using timers in my applications to do things after n seconds after do any other thing. Symptoms: After a random time the Elapse event just stop to be raised. I tried to debug and found something curious: Although I specified AutoReset property to False, at some time in the Elapse event the Enabled property came at value of True!!! After that happen, the Elapse event simply stop to rise. That means that my host applications freeze will waiting some work to be done based on that event. Please analyze this problem. I created a simple example that demonstrates that problem. The code is below this message. Just run it in debug mode, click Start button and wait till form turn red. At that time the problem I mentioned just happened. You can insert a breakpoint just after â??If T1.Enabled Thenâ?? line at â??T1_Elapsedâ?? sub and just after â??If T2.Enabled Thenâ?? line at â??T2_Elapsedâ?? sub to analyze what is happening. I couldnâ??t found an exact time that happened, so you can just start my example application and do other things while wait form turn red, or application stop at your break points. In my example I had a button to restart timer after it stops raising events. It seams that to restart raising Elapse events is just needed to set Enabled property to false and call start againâ?¦ But this behavior is not good! If I start many instances of this example app, them the error appears more offen. Is that a bug?

    - Installing .Net Framework Hello, although not a typical development problem per se, it is a situation that prevents me for developing in the .net framework v1.1. In a Windows 2000 Server with .Net Framework version 1.0.3705 installed, all asp & aspx files ran fine. I tried to install the newest version (1.1x) without uninstalling version 1.0 and installation seemed fine, aspx files were running OK. However, asp pages did not run, with an HTTP Error 500 (Internal server error). An uninstallation of the newest version, alongside a reboot that followed, corrected the problem. The particular server hosts numerous client asp pages, and all of them had the Internal server error, even when application protection was at the "low" setting. Please note that I am not an experienced developer, so I might have missed some tweaks that might make it work. What could have cause the problem?

    - Problems copying output dll's in a post build step I have a solution that has several projects, where many of the projects contain controls that are discovered at runtime, rather than direct reference (this is a requirement). Therefore, the 'copy local' reference copy mechanism of visual studio does not help me move projects around. My first attempt at setting up the solution was to set the output directory for the projects to a common directory. This did not work for the common dll's that are referenced by several projects because the dll is locked, presumeably because of intellisense. This was a while ago, so I don't remember all the exact problems, but they all had to do with projects being in use, preventing me to build. My second attempt (and current) is to let each project have its own output directory, and also copy the output in a post build step to a bin directory. This works most of the time. However, occasionally, the post build step will fail for some projects will fail, claiming the dll is locked - presumeably for the same reason as my first attempt. Why this sometimes works, and others not, I have no idea. My question: is there any way to reliably setup a project so that I can copy the output dll after it builds to another location. It seems like a simple need, doesn't it? Thanx... Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80586

    - Validating Email address with System.Text.RegularExpressions.RegEx Hi John, Using this regular expression: "\w+([-+.]\w+)*@\w+([-.]\w+)*\.([a-zA-Z]{2,4})" and testing it with an email address of dnlwhite@dtgnet.comabcdefg will come back and indicate that is a valid email address but the {2,4} should restrict the values after the '.' to no more than four characters. That's the first part of the neither I was referring to. Using the same expression, the email address dnlwhite@dtgnet.com1234 also returns that it is a valid email address but the [a-zA-Z] seems to indicate that there should not be anything other than alphabetical characters after the '.'. That's the second part of the neither. However, using the ^ and $ like you indicated solves the problem for me. Thank you for that!

    - Bug on DataRow object´s GetColumnsInError method According to .NET Framework v1.1 Documentation, the DataRow object´s GetColumnsInError method gets an array of columns that have errors. This description made me think, develop and test a .NET Windows Application in a disconnected scenario. This application has a WindowsForm with a SqlDataAdapter object that fills a DataSet object. The resultant relational data is then displayed on a DataGrid control. At this time, the data can be modified. In this situation, various instances of the same .NET Windows Application running simultaneously can generate a System.Data.DBConcurrencyException when the SqlDataAdapter object´s Update method is called. Note that the SqlDataAdapter object is configured to use optimistic concurrency. If this exception occurs, the exception-handling structure´s Catch block can implement code to show, for example, a friendly message to the user detailing the accurate cells that had caused the errors. DataSet, DataTable and DataRow objects have the boolean property HasError that help developers to find rows with errors. The only information missing to show in the friendly message is the columns with these errors. To discriminate only the rows is not enough. To get these columns, the perfect method would be GetColumnsInError of the DataRow object. But concurrency exceptions do not set errors in DataColumns objects. In other words, the GetColumnsInError method do not return any columns. I assume that this behavior is a bug. Is there another way to reach this goal? Thank´s, Otávio F.

    - Compact Framework firewall issue MS Support: At one customer site, we can connect to the web from Pocket IE, but we can't from our .NET CF app. If we set the Passthrough setting in ActiveSync to "Work" and try to connect to the web from Pocket IE, we get a popup window that gives the firewall name and asks for a user, password, and domain. We enter an employee's username and password and the domain name and the web site comes up ok. In our .NET CF app, I specify the SAME user, pw, and domain as Credentials on the WebRequest and WebProxy objects, but we still get back a "407 Proxy Authentication" error.

I can't see a way to unlock the file...MailMessage and MailAttachment objects don't have Dispose or Close methods. Any ideas on how to unlock the file??

    - namespaces - what's the point? Hi Can somebody please tell me what namespaces are actually for? I notice that when I start a new project in C#, it puts everything in a namespace of the same name as the project. I found them a bit annoying as when I save a class's .cs file to my 'generic code' folder, and then put it in another project, I have to manually go and change the namespace name. This I find a bit of a PITA. I used VB.NET for a bit and found it didn't have namespaces by default, but that it can have them if it wants. I also found that although C# has them by default, I don't actually have to have them in order to compile. So - they're not necessary, and seeing as I don't like them, why can't I turn them off? And what's the logic behind them being optional in both languages, but on by default in C# yet off by default in VB.NET? Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80556

    - Can you reverse the sort order of a sortedlist class Hi, I am using the sortedlist class but would like the order of the class to be reversed. I know i could loop through the sortedlist class backwards using the index but i would rather have a method on my class which has a private instance of the sortedlist class and be able to specify the order that the sortedlist class is sorted by. Is this possibe? I know an alternative is to use the arraylist class where i can reverse order but this doesn't allow me to access the objects in the arraylist by a key which the sortedlist class does? ANy help would be excellent. THanks T Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80554

    - activating an application I'm developing a stand-alone windows application i VB.NET. The app starts another application via the Process class in background (no window yet) and then establishes a socket communication between them. The main-app has a button which shall activate the 2nd app to display it's main frame. Arguments are sent via the socket and the 2nd app responds and shows the desired frame. And now to my problem: everything works fine except that the 2nd app is not becoming the active application, it is displayed under the main app's window. How can I force the 2nd app to become the active application? Two desired solution alternatives could be: 1) the main app forces the 2nd app to be the active application (via the Process instance) 2) the 2nd app forces himself to be the active application I hope that someone has hints to this!

    - Unable to load dll I am working for migrating java applet - > J# Class Library. Applet was developed as MS VJ++ 6.0 Project . I have VS .NET 2003. I had loaded and installed Browser Controls Official Release v1.1b . I had finished migrating of java code and dll was created successful . I had loaded and installed tagconvert.exe. I had convertred start page with definition of <APPLET> by this tool. Please look at the modified section : <object MAYSCRIPT VIEWASTEXT CLASSID="clsid:a399591c-0fd0-41f8-9d25-bd76f632415f" ID="myapplet" VJSCODEBASE="myapplet.dll#myapplet" > <PARAM NAME = param1 VALUE = "20000"> </object> Then I made corresponding virtual directory under IIS and checked that myapplet.dll is in appropriate folder. Then I typed in IE address field: http://localhost/myapplet/main.html and ....: 1. Message box "The evaluation period of J# Browser Controls Utility v1.1b Beta has expired.Please install a newer release of product". OK. Passed. 2. Empty 'Gray screen' and in status bar in the bottom of IE window : Unable to load http://localhost/myapplet/myapplet.dll What is wrong ? What is my next step in migrating process ? Have I to change something else before to load myapplet.dll ? Thank you in advance , Eugene Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80551

    - Process.GetProcessesByName FileLength Hello, Is it true and a nown issue that I can't retrieve any process from which the filelengt of the executable exceeds 14 characters. In my case for example, I wanted to retreive the running process of a windows service with the name "SomeNameOfTheService.exe" and the Process.GetProcessesByName("SomeNameOfTheService") does return a process. When I try to retreive the processes WorkingSet for example, I get an exception. If I uninstall the service, rename the executable to "MyService.exe" for example, reinstall it and try exactly the same code (Process.GetProcessesByName("MyService") I am able to retreive the WorkingSet of the process. We resolved the problem by renaming the executable to a shorter name, but we are curious to find out if it is a known bug.

    - Re: Internal constructor "visible" outside of assembly. Compiler bug? Martin, OK... I've tried your code and yes, it doesn't compile (I guess I should have tried to run the code before posting!!). I agree with what JD says -- the compiler probably needs this information to hook up the right constructor, *but* in my opinion the accessibility of the constructor should have been checked first by the compiler. There's no point checking if a constructor is a good match if it can't be used anyway. Sure enough, even after adding a reference to DataManager, the following code doesn't compile either, namespace Foo.UserInterface { public class GUI { public void AddItem() { Foo.DataManager.TransactionHandler t = null; CategoryItem category = new CategoryItem(t); } } } with the message: 'Foo.Kernel.CategoryItem.CategoryItem Foo.DataManager.TransactionHandler)' is inaccessible due to its protection level So, the bug is not with the compilers interpretation of the internal keyword, but with the initial check for choosing the right constructor. Would someone at MS like to confirm this? Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80522

    - Time delay/lapse when adding days to a time value Hello, I do the following: DateTime dt = DateTime.Today.AddDays(0); // that's a zero then on my machine, the DateTime.ToString("yyyy-MM-dd") returns a date that is YESTERDAY! Thinking that I'd be clever, I then did the following: DateTime dt = DateTime.Today.AddDays(1); // yup, one day this resulted in the ToString("yyyy-MM-dd") being 2 DAYS in the past! I checked my timezone settings on the computer, and they all show the correct time. Any ideas?? Thanks -- Jake Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80516

    - JMS-style Topics The .Net program I am writing needs to use JMS-style topics. Is there a way to make a MS Message Queue work like a JMS Topic. Or is there a way to access a JMS Topic (preferable WebLogic 8) from a .Net application. Requirements: Multiple listeners on one queue. All listeners get all messages. Messages are deleted after all active listeners have read them. First Attempt Have messages with a limited TimeToBeReceived value. Use PeekNext instead of Receive to walk through the queue. Failed because System.Messaging doesn't expose the PeekNext method available to VB/C++. Any suggestions? Jonathan Allen Tag: Accessing mapped drives from Framework 1.1 & COM+ Tag: 80510

I have a COM+ application that was written using Framework 1.0 and runs on
Windows 2000. The COM+ app runs as domain user who has access to certain
network shares. These shares are mapped on the server. There is no issue on
Windows 2000.

I installed the same app on Windows 2003 without installing Framework 1.0.
Now the application says it cannot find the mapped drive.

Do I need to change some configuration?

Thanks.
James
