    - Why is HttpWebRequest different than IE? Why when I retrieve the response from a URL using HttpWebRequest, do I end up with HTML that is different than IE, even if I set the HTTP_USER_AGENT to be the same as IE? Here's a super-simple example. Note that in IE when you load this URL, there are "£" symbols in front of all of the prices (verified by View | Source), but in the HttpWebRequest response there are not...the actual HTML is definitely different... HttpWebRequest eRequest = (HttpWebRequest)WebRequest.Create( "http://cgi6.ebay.co.uk/aw-cgi/eBayISAPI.dll?ViewBids&item=2340661957"); eRequest.Headers.Add("HTTP_USER_AGENT", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)"); eRequest.Headers.Add("HTTP_ACCEPT", "*/*"); eRequest.Headers.Add("HTTP_ACCEPT_LANGUAGE", "en-us"); WebResponse eResponse = eRequest.GetResponse(); string eContent = new StreamReader(eResponse.GetResponseStream()).ReadToEnd(); Debug.WriteLine(eContent); Any help appreciated. BTW - I thought it might be cookies, so I disabled cookies in IE to see if that made a difference - it doesn't! Tag: Converting VB App for the web Tag: 55718

    - Bug database I was just wondering if there's a bug database for .NET framework. The reason I'd like to see one if that I can be aware of bugs in the framework and won't have to find the bugs the hard way (where I have to eventually realize something doesn't work because of a bug, not because I'm doing something wrong).

The form of the method to send an e-mail is: SmtpMail.Send(from, to, subject, body); I already know who the message is going 'to', the 'subject', and the 'body'. But I can't have the user type in their e-mail address because the app doing all this 'behind the scenes'. How can I get the e-mail address of the current user programmatically?

I am using the ODBC VFP connection drivers to connect the database to .net. I have added the primary key to the table in the DBC but it want be active unless the order is set to it, but from the SQL statement in .net it want allow any order to be set.

    - Lack of Unsigned CLS-Compliant Types in .NET I'm wrapping a native C++ API with MC++. One of the things that I have found frustrating is the fact that most (if not all) unsigned types in .NET are not CLS-Compliant. So, to me, that means you can't use them, say, as arguments in a method because a particular .NET language is not required to support those types. The C++ API has a lot of paramters that are U8, U16, and U32 types. Since the equivalent types in .NET are not CLS-compliant, I find my self using a larger signed type to hold the possible non-negative values of the corresponding unsigned type. For instance, for a U32 in the C++ API, I have to use an Int64 in .NET. While, this works, it's just sort of messy. For example, it forces you to do runtime checks on numbers that are larger than can fit in a U32 in case someone passes in a really large number in a method call (e.g. someone calling a method that takes an Int64 could pass in 4,294,967,306 - this is too large for a U32). I was just curious if there is a better way to handle this? Not making unsigned types CLS-compliant seems somewhat short-sighted to me, but maybe I'm wrong. Any thoughts?

    - ASP.Net and client side control (SelectedIndexChanged) I was wondering what capabilities ASP.Net has at the client level. I have been using a RadioButtonList. My control and additional textboxes look like this: o See item number [ ] o See items from Date [ ] to date [ ] I have the method defined for SelectedIndexChanged event. Basically, I am trying to clear and disable the text selections for the unselected item. Example: private void RadioButtonList1_SelectedIndexChanged(object sender, System.EventArgs e) { if (RadioButtonList1.SelectedValue.ToString() == "ItemNumber") { txtFromDate.Text = ""; txtToDate.Text = ""; txtFromDate.Enabled = false; txtToDate.Enabled = false; txtItemNumber.Enabled = true; } } The problem is that my SelectedIndexChanged event does not fire until the post. I can set the AutoPost=True, but this is still doing a post. That seems like a lot of traffic (back to the server and running code again, etc) just to disable some client level fields. I should be able to do this all on the client because the server does not need to know this information. Well, I could fall back by writing some JScript to do this for me, but I thought there would be a native way for ASP.Net to handle this. Does anyone have any ideas? Thanks in advance!

    - File or assembly name System.Windows.Forms error in Visual Studio.NET Beta 2. I am using Visual Studio .NET Beta 2, because this is the only version I could get. I installed it. Had some problems with starting it. I was getting a message like this: "Visual studio was installed under another user". I found out that the way to go around it is to delete the key from registery.

    - Accessing VB6 activex exe in a .net Windows Service I've been able to acces my VB6 ActiveX Exe via a console application by building a wrapper around my component. But when I do the same thing using a windows service, I get an error during execution saying FileNotFoundException for the ActiveX Exe. This ActiveX exe component is registered on my computer. Is it possible to do this with a Windows Service written under .net? If so, what am I doing wrong. I've added the reference for the component, then did the following: Dim oMyObject as MyACTIVEXComponent.clsServer oMyObject = new MyActiveXComponent.clsServer Like I said, this works with the Console Application, but not with the windows service.

    - O/R Mapping tool like Apple has.....for .NET?!?! Hi! I post this text 1 year ago. But no one really could give me an answer. This is the text that I posted long time ago: I have a fundamental question about The way .NET handles the object orientated way of Persistence. I am coming from JAVA and WebObjects (Apple) World and I am looking for a convenient way of working with objects without seeing any SQL statements only objects. I have used that approach for years on the WebObjects Platform (Enterprise Object Framework) and in Java recently (Container Managed Persistence). I am looking for something like that in the Microsoft world. As far as I understand Microsoft does not distinguish between the Object Model and the Relational Model. The main difference is that the Object model allows n : m relationships and the Relational does not allow them. Here a small example to visualize the problem: Example: There is a Patient object with following Attributes String patientGUID; String name; Int age; Hashtable diseases; (or some other Container like Collection or Array) And there is a Disease Object String diseaseGUID; String name; In the object Model there is relation between Patient and Disease where the patient has his diseases but on the other site one disease can belong to 1..* patients. (n : m) That n : m relationship can not exist within a relational database without a link table that contains the connections between the tables: Patient and Disease. Now, I would like to connect the object Model containing TWO Entities (Patient, Disease) with the relational database (containing THREE tables). Then I want to work with my objects; e.g. create new diseases connect them to existing patients by putting the diseases into the array or create new Patients and connect them with already existing diseases or just change a Patients name. When I am finished I just want to say SAVECHANGES and the database is updated accordingly including all link table entries. So all I have to care about are my objects and the relations between them, some invisible layer does all the dirty work like building SQL, converting the data types and caching. So if I fetch a Patient with a specified GUID I do not have to care about fetching his diseases. They are fetched automatically. If there are too many Diseases I do not care some kind of algorithm handles that problem in such a way that if I have to search all of them for something they are simply there. They are loaded on demand (lazy evaluation) Supposing that the disease has a further connection with some DiseaseType Object/Table and that table has an attribute/column "Description" I can access it by typing the following code: TextField1.Text = currentDisease.type().description() Please note that to retrieve the description value I did only fetch the Patient. The diseases and its types were fetched automatically. Is something like that possible or am I excepting too much of the .NET? ------------------------------------------------------------------- This tool should be a mixture between Microsoft Visio (I mean ORM modelling) and a good object-to-relational mapping tool. Is something like that NOW available???? thx! gicio Tag: Converting VB App for the web Tag: 55661

    - .Net remoting newbie I'm trying to set up the following: 1. a C# server is instantiated by our hosting application on computer A. 2. a C# client on computer B gets a reference to the server with nothing more than the server's URI (or URL, I still don't see the difference). I've found some good documentation on how to create a server that derives from System.MarshalByRefObject, and activate it with the desired URI using System.Rumtime.Remoting.RemotingConfiguration. I cannot, however, find how a client can get an object reference by URI. I am finding plenty of examples where the server is just-in-time created after a client request, but I need the server to run even if there are no clients. Another stupid question, how do I read a server's URI after activation? I see that the System.Runtime.Remoting.Channels.ChannelServices has a static GetUrlsForObject method, is that how I do it? I guess I'm old fashioned in that I believe that if an object has a property, it should expose it through accessors - you shouldn't have to pass your object into a static method on a third party object.

    - .Net network layer have DNS caching flaw? We have an asp.net app that makes an http request call to a server by dns name (there are 3 vips associated with this dns name). For some reason, all our calls are resolving to only one of the VIPs. Running an nslookup command shows all 3 IP address of the 3 VIPs (in different orders on each call); this confirms that DNS is not favoring any of these addresses; it was clearly doing a round-robin. We tried setting the TTL value to 1/0 but this did not work; most calls were still going to the one vip. Running "ipconfig/dnsflush" did not work either. If dns is not the problem, then can .net be the issue? The code leaves the dns resolution to the .NET Framework network layer (the ServicePoint class). We don't explicitly do anything to those objects. Is it possible that this resolves the IP address and caches it? Tag: Converting VB App for the web Tag: 55652

    - Explicit interface indexer implementations? Is there a way to explicityly implement an interfaces indexer? I need to create a collection class, that implements IList, ICollection, and IEnumerable. I'd like to create a custom indexer, with a return value of my choosing, rather than object. Whenever I try, though, the compiler spits out an error (I use C#, BTW). I've tried simply implementing object this[int index] in addition to MyClass this[int index], but got an error. I also tried IList.this[int index] in addition to MyClass this[int index] but also got an error. How does one explicityly implement the indexer of an interface so you can implement a custom one?

    - ADO.net Got speed ?!?! I recently upgraded from VB6 to VB.net and decided that i would like to update a program i use a lot. The Program Connects to a M$ access database (access 2000). It reads in server logs and parses the infomation using the Split command and a select statement to pick out appropriate words. It then inserts each 'record' (each line in the server log contains 1 record) into the database. Under VB6 i used DAO (of course) and my program was fine. The searching was Fast, the data retreival was fast, the input FAST. It took less than 2 seconds to parse a single log file and insert the whole thing into the database. I timed it. To parse 62,398 records it took 6 minutes 23 seconds, Give or take 10 seconds. Now i switched to ADO.net (thinking new = better :oops:) I use Datasets to populate a Datagrid (easy and fast). I use dataadapters to insert the info to the database by updating the datset and using the .update command. Now i guess my question is why does it take my program 38 minutes 54 seconds (give or take 1 minute) to parse 62,398 records? ??!?!!?!?!?!? When i insert the data i dont fill any datasets (something which could if in a loop add vital seconds to each loop) i dont do anything other than add the data then update. Now i cant for the Life of me imagine that the M$ programmers Butchered the SPlit Code. So in my opinion i rule that out. So im afriad the only thing left is the data access.... Sample Code:: ----------------- PlayerDA.InsertCommand = New OleDbCommand("INSERT INTO Players ([Date], [Time], Name, WonID, IPAddress) Values(?,?,?,?,?)", DBConnection) PlayerDA.InsertCommand.CommandType = CommandType.Text PlayerDA.InsertCommand.Parameters.Add("@Date", OleDbType.Char, 50, "Date") PlayerDA.InsertCommand.Parameters.Add("@Time", OleDbType.Char, 50, "Time") PlayerDA.InsertCommand.Parameters.Add("@Name", OleDbType.Char, 50, "Name") PlayerDA.InsertCommand.Parameters.Add("@WonID", OleDbType.Char, 50, "WonID") PlayerDA.InsertCommand.Parameters.Add ("@IPAddress", OleDbType.Char, 50, "IPAddress") DBConnection.Open() Dim newRow As DataRow = DataSet1.Tables ("Players").NewRow() newRow("Date") = "" newRow("Time") = "" newRow("Name") = "" newRow("WonID") = "" newRow("IPAddress") = "" DataSet1.Tables("players").Rows.Add(newRow) PlayerDA.Update(DataSet1, "Players") DBConnection.Close() ---------------- Insert blank... is it that ^^^ ? or is it my Split code? Sample Code: ------------------------------ Do Until LineCount = NumberOfLinesInLogFile UnformattedLogLine = LogFile(LineCount).Word UnformattedLogLineSplit = Split (UnformattedLogLine, " ") UnFormattedLogLineNumOfValues = UBound (UnformattedLogLineSplit) 'Formatting the Info Do Until GettingParsedValues > UnFormattedLogLineNumOfValues Select Case GettingParsedValues Case 0 Case 1 Case 2 Temp = UnformattedLogLineSplit (GettingParsedValues) ParsedArray(0) = Temp.Trim (TrimValues.ToCharArray()) Case 3 Temp = UnformattedLogLineSplit (GettingParsedValues) ParsedArray(1) = Temp.Trim (TrimValues.ToCharArray()) Case 4 GettingName = Split (UnformattedLogLine, "NAME:") GettingNameUpper = UBound (GettingName) If GettingNameUpper > 1 Then GettingNameFoundToSplit = GettingName(1) GettingName2 = Split (GettingNameFoundToSplit, ",") Name = Trim(GettingName2(0)) ParsedArray(2) = Name Else GettingName = Split (UnformattedLogLine, " ") Name = Trim(GettingName(4)) ParsedArray(2) = Name End If Case 5 Case 6 Case 7 GettingWonID = Split (UnformattedLogLine, ":") gettingwonidupper = UBound (GettingWonID) If gettingwonidupper > 3 Then GettingWonIDFoundtoSplit = GettingWonID(5) GettingWonID2 = Split (GettingWonIDFoundtoSplit, ",") WonID = Trim(GettingWonID2(0)) ParsedArray(3) = WonID Else GettingWonID = Split (UnformattedLogLine, ",") WonID = Trim(GettingWonID(2)) ParsedArray(3) = WonID End If Case 8 GettingIP = Split (UnformattedLogLine, "IP:") GettingIPFoundToSplit = GettingIP (1) GettingIP2 = Split (GettingIPFoundToSplit, ":") IPAddress = Trim(GettingIP2(0)) ParsedArray(4) = IPAddress Case Else End Select GettingParsedValues = GettingParsedValues + 1 Loop IncrementLineCount() IncrementRow() GettingParsedValues = 0 InsertingParsedValues = 0 Col = 0 Insert_to_database() Loop -------------------- I really would like some insight from anyone :) I will be absolutely speachless to think my split code is causing this kind of performance degredation especially when its IDENTICAL to the previous version (under vb6).

    - Web Portal Hey all. I'm looking into creating a web portal that has a specific task. We have a multi-user environment and each user has some network space on a mapped drive. Through a login script, the user is automatically connected to their network drive when they log into a computer on the LAN. What I would like to do is have a web site that prompts a user for a username and password (if you have every used Outlook Web Access, it would basally be the same thing). Once the user is authenticated, they have access to their network drive. Nothing else, only THEIR network drive. The project was handed to me very open-ended. Basically, find a solution. I'm not a web programmer by trade - I have some experience, but nothing as advanced as what is being asked of me. So, the first thing I'm looking at is what are my options? I was thinking some sort of extranet setting, or some setup with .NET (if you are thinking VPN as I was originally, that is out -- this is to be a web interface, not VPN access). What are some other ideas out there? Does anyone have any experience with such a thing? Are there any websites out there that may be of assistance (preferably something that starts out simple and basic and works its way up). I would ideally be looking for something already out there vs. programming it. Thanks in advance for your responses!! Anthony Tag: Converting VB App for the web Tag: 55612

    - Soliciting feedback on two features I am collecting data for two features that shipped with the CLR in v1.0 and v1.1. If you use and/or depend on these features, I would appreciate hearing from you with a brief description of how you use these features. 1) .NET Application Restore tool A few sources, including Jeffrey Richter's "Applied Microsoft .NET Framework Programming" book, describe a feature called the "app restore tool", which can be accessed via the .NET configuration tool. There is logging information recorded for each managed application that runs, which can be used by this tool to try to analyze any binding policy (e.g. binding redirect) changes that affected the application, and suggest ways to get your application back to an older state. 2) CacheLocation This is a relatively obscure feature that allows relocation of the GAC via a registry key setting. Support for this feature is limited, and there are a variety of known problems when this feature is actually used. Any comments you have would be apprecaited.

    - c# applet Hi, Im trying to get a c# 'applet' to work. Like demonstrated here: http://samples.gotdotnet.com/quickstart/winforms/Samples/IeSourcing/VB/IESourcing.htm but I can't get it running on my local server (so security should not be a problem) I tried simple examples like: http://www.csharphelp.com/archives/archive109.html but all I get is an empty object box. I use Visual Studio 2003 and windows 2000 professional. I there anything else I need to know? Do I need to sign the assembly of something? Do I need windows server to run a proper IIS. Could a different internal-external IP be a problem? thnx in advance, Paul. Tag: Converting VB App for the web Tag: 55589

    - Design Question I was looking for a clean way to have only get the Id of a reference object within an object The situation is when I want create an object for the purpose of adding it to the db. In that case I dont want to create objects of all the reference objects. IE. I want to create a new Address object to save. In the Db, I only need the Id of the state object in order to save it. Not the entire state object. I thought about adding a StateId in the Address object, but I dont want that. I was also thinking of adding a constructor to set the Id class BaseModel { int ID { get { return _id } set (_id = Value } } } class Address: BaseModel { string State { get { return _state } set (_state = Value } } string City { get { return _city } set (_city = Value } } } class State: BaseModel { string Name { get { return _name } set (_name = Value } } } Tag: Converting VB App for the web Tag: 55588

    - Free tools for .net development Hi all, I'm searching for free and open source solutions to develop .net applications for free. I've found the SharpDevelop IDE (http://www.icsharpcode.net/OpenSource/SD/), the WebMatrix IDE (http://asp.net/webmatrix/default.aspx), to develop in ASP.net, SharpZipLib (http://www.icsharpcode.net/OpenSource/SD/), a library to work with .zip files, and the Magic Library (http://www.dotnetmagic.com/), an user interface library with advanced controls. But I didn't found a free DBMS and an UML tool, that works with .net code. Does anyone knows if there's, and where can I find these tools? Is MSDE free to any .net developer / project, or only for WebMatrix / Visual Studio projects? There's a visual tool (like the SQL Server Enterprise Manager) to work with MSDE databases? Any other tip about free tools are welcome. Thanks in advance, Fabrício de Novaes Kucinskis. Tag: Converting VB App for the web Tag: 55586

    - no touch deployment of crystal viewer I'm looking at the possibility of distributing a crystal report viewer control within an application on our intranet using "no-touch deployment". It'll be internally only, and the crystal.net license documents appear to suggest I can do this, as it's "free runtime" I'm running into problems though since the dlls aren't part of the standard .NET runtime install and even with FullTrust for the web launched forms app I'm still getting security exceptions loading the crystal dlls. I've come across the Assembly.LoadFrom methods, but I can't yet see just how to employ this to load the crystal dlls from a web folder at the right time. I've set the crystal dlls to copy local, yet still no joy. Has anyone had any experience of doing something like this or who could point me in the right direction vis-á-vis internal dll references in an http distributed app, or even conversion of code to enable such functionality.

    - Loading UI Controls Our Windows.Forms user interface uses UserControls for the different parts of the application. The UserControls present a starting point for entity maintenance, data display, and data colleciton and displays related forms. We have constructed a launcher application that among other things creates a new Panel and Tab item when user's select options from a TreeView. The selected UserControl is loaded from a separate assembly and the object is created using CreateInstance then the UserControl is added to the Panel's control collection. The Tab item is used to select the loaded UserControl's that are basically stacked on top of each other, contained in their Panel's. All of the UserControl Panel's belong to one static Panel that is used as a work area. Everything works great except that this is all happening in one AppDomain and after these UserControls are destroyed none of the resources are being collected so naturally we eventually run out of memory. Using separate AppDomains for each UserControl seems like the way to go so that the AppDomains can be unloaded and resources freed. Although we were anticipating the next problem we continued down this path anyways. We can create the UserControls in separate AppDomains but Windows.Forms doesn't like it when we go to add the UserControl, in it's own AppDomain, to a Panel that is in the default AppDomain and we get the message: 'Remoting cannot find field parent on type System.Windows.Forms.Control.' Apparently, this property is not exposed through the TransparentProxy of the UserControl to the launcher application. Questions: 1. How can we load these UserControls in a separate AppDomain in order to free resources after they are destroyed? 2. Can we expose all of the members of the UserControl through the proxy so that Windows.Forms can utilize whatever members are need to site and manage the UserControl in the second AppDomain from a control container in the first AppDomain? 3. Is there another method that could be used to load UI controls from separate assemblies and still be able to free resources after they are destroyed?

    - BUG : Deployment Launch Conditions - Help I am having a real problem with the Launch conditions in VS .NET and can only come to the conclusion that it is a bug. It states quite emphatically in the MSDN that Launch Conditions WILL be executed in the order added. This statement holds true if every Condition has a InstallURL value set. but not if there is no InstallURL value. For Example : I want to check that W2K exists on the target machine before installing SP4. So, I add a Launch condition to check if versionNT=500. I leave the InstallURL Blank as you are supposed to if you do not want the user to continue and just display the OK button to terminate. This works fine by itself I add another Launch condition which check for SP4 viz. ServicePackLevel >=4 which has a InstallURL to enable me to install SP4 if it does not exist (ie sp1, 2, 3 is installed) As soon as I add it it jumps the queue and trie to install SP4 before even checking in W2k is installed. ??? Add a MDAC Check with option to install and it executes after the SP4 check (good) remove the SP4 Checks InstallUrl (ie quit if SP4 or greater not found) and MDAC jumps the queue. This is a problem as I do not want to put a installURL in for W2K Check as I don't want to install W2K (or the app) if the user is running W9x or NT or XP and I definately don't want to install the SP if W2k does not exist (granted that the SP install will moan, but too late!) Things I have tried : Launch condition addition in sequence of supposed execution ( no good) Alphabetical Naming sequence, any addition order (no good) Alphabetical Naming sequence with the correct addition order (no good) Physically Editing and Swopping (in notepad) the entries n the .vdproj file (no good) Adding the W2K check into the default Framework Check section (which happens before anything anyway) (no good) Not that it makes a difference but the application I am building a package for is written in C#...

The problem is that I also need to use my own custom object collection for my custom class. I have already done this with a custom ListBox control by overriding the protected method "CreateItemCollection()" and returning a new instance of my custom collection class which inherits from ListBox.ObjectCollection and that works perfectly.

Two things:

a) get ready for some work, it's not all straight-forward
b) get Ed Robinson's "Upgrading Microsoft Visual Basic
6.0 to Microsoft Visual Basic .NET" (Microsoft, 2003)

Hope that helps.

Hello,

Personally I would try to isolate as much code as possible as COM objects,
so that you reduce rewriting code. If your existing application is already
designed in layers it would be make more sense to reuse these components in
your web application than rewriting the whole thing again.

A big task would be the user interface, since you would have to create this
from scratch and you may not have all the freedom of using Windows controls
as you would have in a VB application.
