    - Maintaining Sessions HttpWebRequest I'm having problems to maintain a session with a remote server using HttpWebRequest in .NET v2 I read a page using, which gives me data and holds it in a session. (classic ASP) The second request I need to use data from that session with the new data I provide from ASP.NET. My problem is that both requests appear to have a seperate Session; asp.net <- classic asp session-related data (session 1) asp.net -> classic asp session-related data + asp.net data (session 2 opened) Instead of sharing one; asp.net <- asp session-related data (session 1) asp.net -> asp session-related data + asp.net data (session 1) Is there a way to force the same session being used by the ASP.NET page? The code I currently am using, but isn't hooking back to the first session: public class Remote { public static string GetRemoteHTML(string ContentURL) { try { // Get HTML data HttpWebRequest wreq = (HttpWebRequest)HttpWebRequest.Create(ContentURL); wreq.KeepAlive = true; if (HttpContext.Current.Cache["ASPSESSION"] != null) { //string Cache = HttpContext.Current.Cache["ASPSESSION"].ToString(); //string CName = Cache.Substring(0, Cache.IndexOf("=")); //string CValue = Cache.Substring(Cache.IndexOf("=") + 1, Cache.IndexOf(";") - Cache.IndexOf("=") - 1); //CookieContainer Cookies = new CookieContainer(); //Cookie Cookie = new Cookie(CName, CValue); //Cookie.Path = "/"; //Cookie.Domain = ContentURL.Substring(0, ContentURL.IndexOf("/",8)); //Cookies.Add(Cookie); //wreq.CookieContainer = Cookies; wreq.Headers.Add("Set-Cookie", HttpContext.Current.Cache["ASPSESSION"].ToString()); } HttpWebResponse wres = (HttpWebResponse)wreq.GetResponse(); System.Web.HttpContext.Current.Cache.Insert("ASPSESSION", wres.Headers["Set-Cookie"].ToString()); Stream streamResponse = wres.GetResponseStream(); StreamReader streamRead = new StreamReader(streamResponse); string responseString = streamRead.ReadToEnd(); streamResponse.Close(); streamRead.Close(); return responseString; } catch(Exception e) { throw e; } } } Is there something I'm overlooking?

    - QUERY: Adding more JS/DOM attributes to DataGrids I know that JavaScript lets us add: ondragenter, ondragover, ondragleave, ondrop events to normal HTML table td tags. This lets us do highlighting of table cells/rows, and capture drag & drop events. So to handle ondrop we can use JavaScript: this.OnDrop = function(obj) { obj.parentElement.style.backgroundColor = "white"; var strData = window.event.dataTransfer.getData("text"); this.InsertRow(obj.parentElement.rowIndex, strData); window.event.cancelBubble = true; } The obj is the object that was dropped onto. So obj.parentElement is the tr element, etc. Does all tr elements implicitly have a rowIndex member which contains the row number of the table? What am wondering is how can one add the ondrop="" attribute to a table which was generated from a DataGrid? If it is not possible adding JavaScript/DOM attributes to DataGrid's generated tables, then is there any way to capture these window.events and knowing exactly which DataGrid table row/cell it was dragged onto? I was told to look for "DataGrid Overviews" at 4guysfromrolla.com but could not find anything about it. Not even google.com could help. Is there no drag and dropping support for ASP.NET datasource tables? Tag: PadLeft ?

    - RadioButtonList .NET 2.0 Breaking Change Can anyone shed any light on this issue. We were generating HTML outside of a HttpContext in 1.0 and 1.1 by building a control structure the calling RenderControl on the parent. There has been a change to RadioButtonList Render method that causes a null reference exception when Render is run without a HttpContext. if (!base.DesignMode && !this.Context.Request.Browser.Tables) This isn't listed in the breaking changes and I have never read that you can't render controls without a Context.

    - Check for Common character sequence ( I will pay)? Hi, Anyone know how I can do this? I will pay anyone via PayPal who can do this for me. Let me know? Write a function in C# that takes in an array of ASCII strings and finds all common character sequences. A common character sequence is defined as 3 or more adjacent characters that appear in more than one string in the array. Use the following function signature for your response: //C# class FoundString { public int cOccurrences; //count of times this substring //occurred in the value array public string szSubstring; //substring that was found } FoundString[] countSubstrings(string[] rgszValues); Ex. input of ("will-01", "a_williams", "will_01_iam") would return "wil" (cOccurrences = 3) "will" (cOccurrences = 3) "ill" (cOccurrences = 3) "iam" (cOccurrences = 2) Provide coded unit tests cases that exercise your solution. For extra credit: 1a. Order the results in descending order based on the number of input values each sequence matched. 1b. Prune the results by removing all results that are a substring of another result that matched the same number of input values. In the above example "wil" and "ill" would both be discarded because they are both a substring of "will" and all 3 values match 3 input strings Tag: PadLeft ?

    - Microsoft .NET Framework Primer for the Visual Basic Developer I find it mildly amusing this following paragraph from a tutorial MS wrote on an introduction to VB.Net for VB6 developers. It's written in such a manner as to sound as the VS does something for you (auto-generates) that previous versions did not. As if you had to write the Form class by hand in VB6, lol. "Although the designer is very similar at first glance, many enhancements make Windows Forms development easier while giving you more power and flexibility. One of the most significant changes from Visual Basic 6 is that all controls and other UI components are actually classes in the Framework Class Library. When you drag a TextBox onto a form, Visual Studio 2005 auto-generates a field to hold a reference to a TextBox object and writes the code for instantiating a TextBox object when the form is initialized. The visual designer also writes the code for setting the properties of the control. If you change the BackColor property of the Text- Box in the Properties window, Visual Studio 2005 generates a line of Visual Basic code that sets the BackColor. Figure 1-9 shows some of the auto-generated code for the login form shown in Figure 1-8." Tag: PadLeft ?

    - Outlook Add In is not shown for 1 user... Hi, I developped some time ago an Outlook Add In (VB.NET 2005) that worked fine during several months with all the users. Suddenly, 2 weeks ago it stopped working for one of the users. The administrator desinstalled it and installed it again, but that didn't work. i did the same, desinstalled it, rebooted, removed everything I could find about it in the registry of file system (nothing in both cases), reinstalled it, but still not working... It works for every user on that pc, but not forthis specific user... I added a MessageBox at the beginning of the "Private Sub ThisApplication_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup"-startup to be sure if it started or not, but the MessageBox is never shown... Does anybody has any idea why this happens? and how to find a solution for this? Is there somehow a way to see which Add Ins are available for who? Thanks a lot in advance, Pieter Tag: PadLeft ?

    - Assembly.LoadFrom() ... multiple component versions You can load multiple versions of the same assembly into the same process using LoadFrom(). However, (straight from Don Box's book) this can cause problems (for example, multiple copies of static fields... one for each instance of a loaded type). I remember in the book he mentioned that you could set attributes to prevent loading of different versions of the same assembly, but I can't remember what the attributes were... and he also said that at the time of the writing, they weren't effective. Any hints? Also, are there any 2.0 changes with regard to the above? Thanks!!! Andrew Tag: PadLeft ?

    - How can I pass a different class and method name to a component? I have a lot of very similar code that moves data from place A to place B. Code gets new rows to be moved and for each row calls a component. In addition to that it keeps statistics of how many records were moved and how many were rejected, what was the throughput, etc. Without going into too much details, these are two examples: // Example 1 MyCompany.MyComponent o = new MyCompany.MyComponent(); foreach (DataRow dr in dt) { // Get pk o.MoveOrders (pk); } // Example 2 MyCompany.AnotherMyComponent o = new MyCompany.AnotherMyComponent(); foreach (DataRow dr in dt) { // Get pk or OrderDate o.MoveBills (pk, orderDate); } I would like to reuse common code by putting it into a base class. My question is, how can pass different class name and method name to a generic component? For example, in the first case I want to instantiate "MyCompany.MyComponent" and then call "MoveOrders" method with one integer parameter. In the second case I need "MyCompany.AnotherMyComponent" class with "MoveBills" method that takes two parameters, one int and another one DateTime. Is it possible? Thanks, -Stan Tag: PadLeft ?

    - user.config - where is it stored? Hi All, In my project I have a complex of applications which need to share the same settings. The settings are set in the main application. Other application need to read this settings. OpenMappedExeConfiguration method allows me to do this if I can provide the full name to the user.config. Here http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/html/vbmysettings.asp it is explained where user.config is stored: ************************* The user.config file is created in the <c:\Documents and Settings>\<username>\[Local Settings\]Application Data\<companyname>\<appdomainname>_<eid>_<hash>\<verison>. Where: * <c:\Documents and Settings> is the user data directory, either non-roaming (Local Settings above) or roaming. * <username> is the user name. * <companyname> is the CompanyNameAttribute value, if available. Otherwise, ignore this element. * <appdomainname> is the AppDomain.CurrentDomain.FriendlyName. This usually defaults to the .exe name. * <eid> is the URL, StrongName, or Path, based on the evidence available to hash. * <hash> is a SHA1 hash of evidence gathered from the CurrentDomain, in the following order of preference: 1. StrongName 2. URL If neither of these is available, use the .exe path. * <version> is the AssemblyInfo's AssemblyVersionAttribute setting. ****************************** Ok, I load main application's assembly using reflection and try to find the path. Everything is ok until I come to <hash>. My assembly is strong named so I can take it's strong name and calculate a hash. But the real path to the user.config of my application ends with .._wyj0d3ad0f1pysfh0zttpxzlifbcmb3d which doesn't look like string representation of a binary array. Does someone know how to find the path to user.config? Thanks, Artem Kliatchkine Tag: PadLeft ?

    - Using Assembly.Load(byte[]) to load multiple versions of dll, and AppDomain.AssemblyResolve Using dotnet 1.1, sp1, C#. I have assembly "A", which references assembly "B". Neither of these assemblies are stongly named. I have an application which uses a plug in architecture, to load assembly "A" using Assembly.Load(byte[]). The app (actually a web service) needs to be able to have loaded multiple versions of assembly "A" at the same time. eg. assembly "A" version 1, and assembly "A" version 2. The directory structure looks like this : -- Application's bin directory -- v1 subdirectory (contains "A" version 1, and "B" version X). -- v2 subdirectory (contains "A" version 2, and "B" version Y). i.e. "A" version 1 should use "B" version X, and "A" version 2 should use "B" version Y. Both versions are loaded into the same AppDomain (The application's current AppDomain). Assembly.Load(byte[]) is being used to load the versions of assembly "A". This works fine. My problems start when the versions of assembly "A" use the AppDomain.AssemblyResolve event to try to load the required versions of assembly "B". Ideally, I want to use that idea that assemblies in the same subdirectory should use each other at runtime. There does not seem to be enough information from inside the AppDomain.AssemblyResolve event to work out which subdirectory's "B" to load. Any ideas ? eg. Load different versions of "A" into different AppDomains, make assembly B version numbers more closely coupled with assembly "A"s version numbers ? TIA, Stephen Tag: PadLeft ?

    - windows service apllication Hello, Initially I created a socket server (listener) application which blocks and waits for communication from client socket applications running on other Windows XP machines on the network. Everything seemed to be working fine (where the listener simply displays a form whenever it recieve's communication from a client) then blocks again. However on logout/shutdown form machines running the listener, the listener seems to hang and the user always have to click "end now" on a dialog box that pops up. Without being sure of the source of the problem I decided to try making the listener run as a service and went about creating a windows service application which uses the system.timers.timer component. The Tick method is then used to start the socket listener. The service gets installed and starts without any apparent errors but nothing happens when i use clients to communicate with the service. Am I going about this correctly? Any advice is appreciated. Sean. Tag: PadLeft ?

    - How to compute CRC I am processing a very large (20+ GB) file. As part of my processing I need to compute a CRC or hash value for the file. To improve the efficiency of my algorithm I'm looking for a way to do this without having to read the file twice (once for my processing and again to compute the hash). My processing involves reading the file one 64K byte chunk at a time into a byte array. As I'm reading the file I'd like to generate a running CRC or hash code that I can update each time I read another bunch of bytes from the file. Is there a way to do this without writing my own CRC32 implementation? Thanks! - Bob Tag: PadLeft ?

    - Is Dot Net Really belongs to Object Oriented ? Correct me if I am wrong. In an Object Oriented environment each and everything are objects. That means we cannot directly instantiate a class nor we can directly reference a member belongs to a class i.e. ClassName.MethodName () If I am right in that sense, we are doing the just opposite in .NET. For example in the sample Hello World Application given below Imports System Class HelloWorld Public Shared Sub Main () Console.WriteLine (?Hello World?) End Sub End Class As per MSDN Console is a Class defined inside the System Namespace. Here we are directly calling the Method () defined inside the Class Console.

    - Redirect StdIO-Problem: Console.In.Peek() hungs ! Hi All ! I think, there is a bug in the System.Console class related to use the STDIO streams. I am doing a very simple thing in a console-based program named CS [ConsoleTest] Console.In.Peek(); and the program hungs if no parameters were provided on the commandline. If I use simple redirection like "echo "hallo" | cs.exe" everything is fine. I thing this is a bug in the console class. Because I am delaing with different streams, I need to pass "TextReader" instances to a method and have to expect, that it works with all types of TextReaders well. I have urgent needs, because I have to distribute an I/O-filter very quickly. I am MSDN Universal Abonnent and can require support! Thanks so far and best regards, Manfred Note:There was a similar request [perhabs from a person, which has possibly no validity of claim], but no answer!

    - ClickOnce LONG DELAY When clicking the link from a client PC that points to the MyApp.application file, initially there is a windows that pops up in the upper left hand corner of the screen that says "Verifying Application Requirements" This windows seems to pop up very quickly and then just goes away. Then, instead of the program starting to download with progress bars, there can be anywhere from a 10 second to several minute delay before the progress bar window finally shows up. The progress bar / install windows will always show up, install, and eventually the program runs, but the huge delay when it appears that nothing is going on is quite troublesome. We actually have warnings next to the link telling users to be patient that the program will eventually load, but the long delays can be frustrating. Something must be going on because this doesn't happen only on one client, but all of them without fail. The time will vary, and it doesn't seem to be predictable, but it does happen. Has anyone else seen this? Does anyone know the reason for this? Is there anything I can do during publish time that will eliminate this problem? I've googled and googled but I can find any other mention of this problem. Thanks. Tag: PadLeft ?

    - Deserializing XML file Hi, How do I deserialize an object based on a random XML file? I have tried using the XMLSerializer.Deserialize method but it does not set the values for the members. I need tto do this because I am trying to invooke a web service by passing this object as the input.

    - random_shuffle behavior differs, VS 2003 versus VS 2005 random_shuffle function produces different results for debug and release executables when compiled with /clr This console app, built without /clr using VS 2005, produces identical results for debug and release executables. But add /clr to the compile line and two different results occur. The debug result matches that of the "non-clr" executables. This poses a serious problem for QC of mixed-mode applications built with VS 2005. Lack of reproducibility of release executable behavior in a debugging environment is unacceptable. This discrepancy has not been observed using VS 2003. Will this behavior be fixed in a future release of VS 2005? // Shuffling.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> // C++ STL cout, endl #include <numeric> // C++ STL generic numeric algorithms (partial_sum) #include <queue> // Standard C++ Library queue using namespace std; int _tmain(int argc, _TCHAR* argv[]) { // create the deque (1, 2, ... 10) . . . std::deque<int> myDeque(10, 1); partial_sum(myDeque.begin(), myDeque.end(), myDeque.begin()); for (unsigned int i = 0; i < myDeque.size(); ++i) { cout << myDeque[i] << ' '; } cout << endl; // . . . and randomize it random_shuffle (myDeque.begin(), myDeque.end()); for (unsigned int i = 0; i < myDeque.size(); ++i) { cout << myDeque[i] << ' '; } cout << endl; getchar(); exit(0); } Debug (no /clr) 1 2 3 4 5 6 7 8 9 10 9 2 10 3 1 6 8 4 5 7 Release (no /clr) 1 2 3 4 5 6 7 8 9 10 9 2 10 3 1 6 8 4 5 7 Debug /clr 1 2 3 4 5 6 7 8 9 10 9 2 10 3 1 6 8 4 5 7 Release /clr 1 2 3 4 5 6 7 8 9 10 10 1 9 2 4 8 5 6 7 3 Tag: PadLeft ?

    - FileIOPermissionAttribute - how to use it Hi, I have a question concerning the usage of the FileIOPermissionAttribute. I have an assembly (essentially a loader) which reads files, does stuff with the contents and writes records to an SQL database. The paths to the files on which it operates are passed as parameters on a method within the assembly. I'd like to be a diligent programmer and tie-down the security requirements for the assembly. From the point of view of file IO, the requirements are as follows: 1. Be able to read the contents of any file passed to the assembly method. 2. Not be able to write to any file, anywhere. I cannot see how to achieve this with the FileIOPermissionAttribute. All of the examples that I can find show IO permission being granted or denied to explicit, hard-coded files or paths, eg: [FileIOPermission(SecurityAction.Assert, Read="c:\\")] This sort of thing doesn't strike me as being very useful for an attribute at the assembly, class or method level. It requires the path or file-name to be hard-coded, akin to having hard-coded paths and names in normal code. If I want to specify read-access to any local file or deny write access to any local file, I seem to need to know the layout of the drives of the target machine at compile time. Obviously I don't know this. E.g. does a particular target machine have a local C drive, or local C & D drives, or has the owner been particularly strange and re-arranged the drive mappings so that the local drives are C and H etc. So my question is this: Is there a more general means available to allow the programmer to specify the file IO requirements via the FileIOPermissionAttribute when the layout of the target file-system is not know at compile time?

    - SmtpMail connection question. I've got 2 different applications that use the same SMTP server. One is written in C# and uses the SmtpMail class. The other is in C++ and uses the ATL CSMTPConnction class. The SmtpMail code works just fine. The CSMTPConnection code fails. In digging down into the ATL code, I can see where it issues a "HELO" command to the smtp server and reads the result to check for a "250" return code as an indicator of success. Using telnet, I can verify that 250 is returned from a "HELO" command. The big wrinkle here is that the smtp server is using a 3rd party smtp security product. I suspect that the ATL code is doing something that the 3rd party product does not like. So, finally, my question is about how the SmtpMail class is successful. Does the underlying code issue a "HELO" command at all? TIA - Mitch Tag: PadLeft ?

    - Recursive WebRequest.Create() The WebRequest class implements IWebRequestCreate and hence, a method Create. This method has two other overloads, one of which is a private method.

Hi,

I came across a doubt on the String.PadLeft Method.The doubt is this --
What's difference it make if the argument to this function carries an
integer whose value is less than the length of the string object

For example in the sample code below(VB.NET) I could not see any difference

Dim str As String
str = "BBQ and Slaw"
Console.WriteLine(str.PadLeft(5)) ' Displays "BBQ and Slaw".

Console.WriteLine(str.PadLeft(15)) ' Displays " BBQ and Slaw".

I could not notice any difference with the output of str.PadLeft(5) and
the original str string.Both carries the same message "BBQ and Slaw"

Can any one tell me what is the use of this particular function if the
padleft paramater is less than the length of the string.

None. It is used to add padding to a string that is shorter than the number
passed. If a string is longer, it doesn't need any padding.
