    - The Register directive for the referenced assembly Hello everybody! I am authoring my custom webcontrol and faced a very difficult problem. I have two assemblies: the first one contains some base classes and the second one contains a class which 1) Inherits a class from the first assembly 2) Contains references to the first assembly's class instances. When I drop the control from the second assembly onto a form, it adds references for both assemblies to the project, but it creates only one Register directive (which defines the TagPrefix) in the aspx code. At design time the control is displayed fine, but at run-time it throws an exception. To solve the problem one should manually add the Register directive for the base assembly. Does anybody know what should I do to that the Register directives for both assemblies were created automatically when one drops the control onto a form? Any help is appreciated Thank you in advance!

    - remove an item from a drop down list Hi, if anyone can help me with this i would apreciate it. I have 2 drop down lists, and between them, they have some values that are similar. How can i fill the second drop down and remove the item thats selected in the first drop down, so that the same item doesnt appear on both drop downs? i have tried doing this after i load both dropdowns: 2ndlist.Items.Remove(1stlist.SelectedItem.Text) BUT NOTHING HAPPENS. I still get the value on both drop downs it only works with the index: 2ndlist.Items.RemoveAT(1stlist.SelectedIndex) BUT its not right since drop downs dont have the same amount of items.

    - General access denied error adding user to group when impersonating Hi, I'm successfully impersonating an administrative user (using KB306158). I know it is successful because after the impersonation, the WindowsIdentity.GetCurrent().Name returns the admin credentials (before the impersonation it returns the logged-in user's credentials). I'm also testing the user's role (using IsInRole()) and receive True for Administrator. However, when attempting to add a user to the group, I receive a 'UnauthorizedAccessException: General access denied error'. Assuming that I copy-pasted the code from KB306158, so that I have the impersonateValidUser() function: this.Response.Write("<BR>before: " + WindowsIdentity.GetCurrent().Name); // returns the current non-priviliged user if( impersonateValidUser(admin, domain, password) ) { this.Response.Write("<BR>after: " + WindowsIdentity.GetCurrent().Name); // returns the actual admin account WindowsPrincipal principal = new WindowsPrincipal( WindowsIdentity.GetCurrent() ); this.Response.Write("<BR>in role: " + Convert.ToString( principal.IsInRole( WindowsBuiltInRole.Administrator ) ) ); // returns True // ... (code which retrieves existing group and existing user ldap path) // fails 'UnauthorizedAccessException: General access denied error' grp.Properties["member"].Add(userPath); grp.CommitChanges(); } Thanks in advance, Elad.

    - Architecture: Scalability VS Performance This is a design / inheritance qus. I have class Task. This is a base class for some specific tasks Say WorkOrderTask : Task TimeSheetTask : Task Now Task has a function GetDetails() which gets all info about task. This makes a database call. I override this in the derived class. For implementing this in derived class i see following 2 approaches. Approach 1. WorkOrderTask .GetDetails() { Calls base.GetDetails(); to get base details, populates in the object Gets details specific to WorkOrderTask, populates in the object returns; } Approach 2. WorkOrderTask .GetDetails() { Get details specific to WorkOrderTask as well as the base class details, populates in the object returns; } The problem with Approach 1 I have to make 2 database calls. Approach 2 If theres some change in base class I need to take care of these in all the derived classes as well. Whereas, Approach 1 is advantageous here as by modifying only the Task.GetDetails funciton ( this is the base class ) function i have all the values and i do not need to touch the derived classes. Was thinking this might be a very common problem, so perhaps many of might be able to guide me on the approach i must take here. Perhaps anything other then the two i have talked about.

    - Visual Studio 2003 compatibility with original Visual Studio .Net My old laptop has the original version of Visual Studio .Net running on Windows 2000. My new laptop has Visual Studio .Net 2003 running on Windows XP. I imported an existing Web project to the new laptop, made some modifications, rebuilt the project, and pushed the changes, including the DLL and PDB files, to our "test and QA" server. The application blew up on the first screen; the error was something like "unable to find the query string collection object". I copied the changed .aspx and .aspx.vb files back to the old laptop, rebuilt the project, and again pushed all changes, including the DLL and PDB files, to the "test and QA" server. This time, no problem. What do I have to do so that our servers, including our client's production servers, can run applications developed with VS .Net 2003? Much obliged.

    - 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?

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.

    - 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: Copying files via URI 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: Copying files via URI Tag: 75465

    - StreamWriter Adds FFFE at the start of the file with Unicode Encoding!! Hi , all I'm trying to write unicode to a file for another app (not developed with vs2003) to read it. I used StreamWriter with unicode encoding.but I was surprised that the streamwriter adds FFFE to the start of the file,which stopes the other app from reading it!! any idea how to stope it frome doing that,do I have to use another class #####writer that supports unicode? help me Please!

    - Chicken and egg problem with FileIOPermission and Environment.GetFolderPath("My Documents") Hello, I am trying to assert a FileIOPermission to get access to the "My Documents" folder. To do this, I am using this code: FileIOPermission FilePathPerm = new FileIOPermission(FileIOPermissionAccess.AllAccess, Environment.GetFolderPath(Environment.SpecialFolder.Personal)); The problem I'm running into is that the code above throws a permissions acception. GetFolderPath method requires FileIOPermission to the path is is returning before it can return anything. So, it can't be used to return the path permissions are being requested for. So, how do I accomplish this task of requesting permissions for "My Documents" when I don't know ahead of time what the full path to "My Documents" is and I can't get access to it through the GetFolderPath method? Is there an environment variable or something that would hold this value? Thanks, Phred Tag: Copying files via URI Tag: 75426

    - Macro Question Hello I am writing a macro in Visual Studio .Net 2003, and I was wondering if it is possible for a macro to access properties of objects that are selected. For instance, assume I have the following object declared (on a different page, but it can still be instanciated) Class rectangl Private _height as doubl Private _length as doubl Public Property height( Public Property width( End Clas Now, is there a way, using a macro, to take a name of an object type and then print the properties to the screen For instance - the object name 'rectangle' would print out 'rectangle Property: heigh Property: weigh I'm relatively new to this, and I suspect that if it could be done, it might be done using reflection, but I don't know how to approach it Can anyone provide help in this matter Thanks Andrew Wied Tag: Copying files via URI Tag: 75420

    - Select a Specific Row in DataGrid at Form Load Time I have a DataGrid control in a Windows Form. At the time the form is displayed, I would like to have a specific row (record) being selected and highlighted. At form load time I can populate the data source of DataGrid control. At what time (handler of which event) should I go through the DataGrid control to locate the row and select specific record? Thanks. Jian Dai Tag: Copying files via URI Tag: 75415

    - 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: Copying files via URI Tag: 75406

Hello all,

What is the best way to copy files over a network? The remote server will
be accessed via http, and the files copied to a local drive.

I have tried using the System.IO.File class, but get URI errors when
accessing the remote files.

Thanks, Mike

Try either WebClient or HttpWebRequest/HttpWebResponse.

You need to do an HTTP download. You can do that using Indy, which is free:
