    - Optional values? Hi, In my C# applicaiton, I use ADOX to reach and check the user permissions in my Access database. To do this, there is a function named "GetPermissions". This function gets 3 arguments where the 3rd one is optional. But the C# compiler doesn't accept giving only 2 parameters and whatever I put into the third one (null, "", etc.) I get an exception. I want to ask whether anybody knows how to handle those optional parameters in C#? Thanks in advance... Regards, Özden Tag: System.Text.RegularExpressions Tag: 96258

    - FileSystemFileWatcher I write an application. When one file is created in the specified folder, it runs one method (using SystemFileWatcher). I test my app carefully. But my customer report that: When copy file to that folder (that folder is empty) , that method doesn't run. I read file log, and I reliaze that: event "OnCreated" of FileSystemWatcher isn't raised. Besides the reason is coping overwrite file (will not fire OnCreated event), are there any other reasons ? Thanks a lot !!! Tag: System.Text.RegularExpressions Tag: 96255

    - About IE Hosted UserControl auto download I have just finished an IE Hosted UserControl named MyUserControl, which can automatically download from IIS site if I assigned the URL to http://MyComputer/MyFolder/index.htm. However, if I assigned the URL to http://www.MyCompany.com/MyFolder/index.htm or http://localhost/MyFolder/index.htm, IE will not automatically download the MyUserControl from iis. Where three of MyComputer, www.MyCompany.com, and localhost means same machine. Why? They are same machine, why only a shortly computer name can download, but long site name and localhost cannot download? Because of security issue?

    - Calling WebService from Windows App causes Windows App to never qu I created a WebService on the order of a WindowsUpdate type of functionality. I call the following routine, and once I've done that, my Windows Application stays around as a running process forever (or until I kill it with task manager). This is very odd. The application does not appear to hang, it seems to work perfectly. It even appears to exit, but looking in task manager you can see that it stays in memory. There must be something I have to do to properly dispose of my web service, but I'm not sure what it is. Can anyone help? (Yes, I call the dispose method, but that doesn't appear to do anything). public string[] getVersions() { FileVersionInfo myFileVersionInfo; string[] tempList; string fileName; string[] dirs = Directory.GetFiles("http:\\xxxxx\\modules"); tempList = new string[dirs.Length]; for(int x = 0; x < dirs.Length; x++) { myFileVersionInfo = FileVersionInfo.GetVersionInfo(dirs[x]); fileName = dirs[x].Substring(dirs[x].LastIndexOf("\\")+1); tempList[x] = fileName + "," + myFileVersionInfo.FileMajorPart + "." + myFileVersionInfo.FileMinorPart + " Build " + myFileVersionInfo.FileBuildPart + "." + myFileVersionInfo.FilePrivatePart; } return tempList; } Tag: System.Text.RegularExpressions Tag: 96239

    - C#2.0 Form to COM object? I have a standalone app created in C# that is used to browse a database of archived documents called DocDB. We have some older legacy code written in Delphi that we wish to enhance with the DocDB's functionality. My idea was to give DocDB methods for controlling it from a seperate process via COM (much like Word for example, but with only a few public methods) I have defined public methods in my forms based class, I have used an SNK file, I successfully installed it into the GAC and run regasm. I have also created a public interface for the few methods I need. But no matter what I have done, the TLB that I create never exposes the public methods when imported into my legacy app. The code looks something like this (using C# 2.0): namespace DocsDB { [Guid("3100EBCE-1E40-500b-A247=AD-C777D72BB2ED")] public interface IDocsDBUI { void ViewDocsForLoan(int loan); void IsVisible(bool visible); void Quit(); } [Guid("AA218A41-ED34-5f4e-95C1=AD-0F1DB0402AD9")] [ProgId("DocsDB.App")] [ClassInterface(ClassInterface=ADType.AutoDual)] public partial class frmMain : Form, IDocsDBUI { public frmMain() { InitializeComponent(); } public void IsVisible(bool visible) { this.Visible =3D visible; } public void Quit() { this.Close(); } public void ViewDocsForLoan(int loan) { // do something here } } } Can someone tell me what I might be doing wrong? A small working example would be very much appreciated. Tag: System.Text.RegularExpressions Tag: 96227

    - when is hashcode used? Hello All, I have been facing this bizarre problem within a combobox having a list of UK postcodes. When I assign the SelectedItem propoerty of the combobox, a completely different item was actually selected in the combobox. I broke into the code at the assignment statement and then looked at the values for different items in the watch window. It looked something like this : postcodeObj : EH11 1LQ comboBox1.SelectedIndex = -1 (nothing currently selected) comboBox1.Items.IndexOf(postcodeObj) : 1614 comboBox1.Items[1614].ToString() : EH11 1LA (something different to what i am intending to set as selected item) I also found out that my item was at the location 1621 in the combobox items. The combobox is no sorted, and I couldn't figure out what was going wrong here, till I added 2 more things in the watch window comboBox1.Items[1614].GetHashCode( ) comboBox1.Items[1621].GetHashCode( ) These 2 values appeared to be same, Now I remember that I have overriden the GetHashCode() method in my postcode object to return a hashcode, it creates a hashcode based on the postcode string and one more attribute. (XOR the number and the hashcode of the string) My question is, Is hashcode used internally by the 'SelectedItem' set method? Is there any way for me to get round this problem? I have the postcode strings and a unique number, Can I generate a unique hashcode from this combination? I don't want the number to be my hashcode.

Not only do I have to know who is currently using a remote desktop session, but also need to prevent other users from logging in. I found a way of getting a list of running processes and link them to the owning users, but there must be a better way... for example, Terminal Server brings a tool called query.exe which shows the users currently logged in.

    - Implications of using typeFilterLevel=Full after strong naming assemblies Hi, Env: Windows 2003, VS 2003, .Net 1.1 We just started strong naming our assemblies and ran into a .Net Security Exception when remoting between ASP.Net and our Windows service. The remoting call that failed with this exception returns an array of DataRows (from a strongly typed DataSet) from the service to ASP.Net. All our assemblies (apart from Microsft.Security.SSPI sink) are private. The exception is: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request failed. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [SecurityException: Request failed.] Anyway, we solved this by setting the 'typeFilterLevel' to 'Full' in our server config file: <formatter ref="binary" typeFilterLevel="Full" /> After some research I found that people have mentioned security and possible performance issues with setting this level to 'Full', so I've a few questions on the implications of opening this up: 1) Why does strong naming a private assembly cause this problem, when an unnamed private assembly works fine? 2) I doubt it, but are there any performance issues? 3) The security issues appear to be from spoofing and code injection: http://blogs.msdn.com/manishg/archive/2004/10/27/248841.aspx Can you please confirm that these security issues existed before we strong named our assemblies and had to set the typeFilterLevel to full? This doesn't mean we'll ignore the vulnerabilities (we already authenticate callers), but we're just trying to understand the impact of this change. Thanks very much, Stuart PS. This is reposted from 'microsoft.public.dotnet.security' as I didn't realise that one wasn't a managed group. Tag: System.Text.RegularExpressions Tag: 96178

    - InvokeRequired and CreateGraphics Hi, Here is what the documentation of InvokeRequired says : "In addition to the InvokeRequired property, there are four methods on a control that are safe to call from any thread: Invoke, BeginInvoke, EndInvoke and CreateGraphics. For all other method calls, you should use one of these invoke methods when calling from a different thread. " Could someone explain me why a call to CreateGraphics is "safe" ? One of my backgroud threads calls CreateGraphics on a control but when this control is destroyed (ie the application is closed), this thread is blocked on the call to CreateGraphics and isn't aborted. I don't understand why a call to Invoke isn't required in this case. Thanks Fabien Tag: System.Text.RegularExpressions Tag: 96167

    - Saving the state of UI Hi, User can adjust the size of columns of a table or the position of splitter in UI. We want these adjustments to be remembered when we restart the application. Currently, we are saving these adjustments by the user in an XML and saving that XML. We read the XML upon restart and make calls to set the adjustments. This approach becomes difficult as we add more controls and more settings can be made by the user. What other techniques can be use to save (perhaps automatically) the STATE OF UI? As in Java, can we use Serialization of UI to save its state [Java's Swings control are serializable while in .Net, Form and all the controls are not serializable]? Any pointers to articles on various approaches to SAVING THE STATE OF THE ADJUSTMENTS made by the user will be greatly appreciated.

    - Socket and multi-threading Hi, Socket class documentation says that it is not thread safe. We understand that if do simultaneous sends on ONE socket then it will be a problem (or simultaneous receive). Can we create TWO threads on OUR OWN such that one will do SEND and one will do RECEIVE using the SAME socket reference? This means that two threads WILL BE in the same SOCKET object - one doing receive and one doing send. We know we can use asynchronous calls on the socket to achieve this but whether we can do this using our own threads. Any pointers to official documentation that shows that this is permissible?

    - Simple string encryption (solution) This message includes a solution for encrypting and encoding a string into a "safe" character string that you can read or pass in ASP.NET querystrings, and then decode and decrypt it back to its original form. If you find it useful, please let me know. I had an issue with a web site that I was working on where I needed to pass around a moniker in my querystring. While the database itself performed relevant security checks, I didn't want to expose this to my users. The problem I had is that I just wanted to encrypt/decrypt a string without having to know or understand anything about the cryptography namespace. I also wanted to be able to pass this value around in my QueryString. This code takes the unmodified symmetric encryption example code that Lion Shi posted a while back on Usenet, converts the resultant bytes to hex and then performs a simple substitution for aesthetics. If you plan to use this for your own purposes, and since I've posted this publicly, I recommend you change the values of the two variables having the value of "password" (they don't have to match, but if I remember what I've read on DES, I believe they need to be a multiple of 8 characters in length). The code that Lion Shi originally posted is located here: http://groups-beta.google.com/group/microsoft.public.dotnet.languages.csharp/msg/eb7712e9e5cc1045?hl=en This is the modified version that encodes the resultant byte arrays into strings. It seems to work on the three strings that I've tested it with, but I make no guarantees on its security or reliability. Usage Example: string s = "Raw Text String"; Response.Write(s); s = Encryption.Encode(s); Response.Write(s); s = Encryption.Decode(s); Response.Write(s); Source: using System; using System.Collections; using System.IO; using System.Security; using System.Security.Cryptography; using System.Text; public class Encryption { private Encryption(){} static byte[] m_bDESKey = ASCIIEncoding.ASCII.GetBytes("password"); static byte[] m_bDESIV = ASCIIEncoding.ASCII.GetBytes("password"); static char[] hex = "0123456789ABCDEF".ToCharArray(); static char[] munge = "ZXCVASDFQWERPOIU".ToCharArray(); public static string Encode(string text) { byte[] data = DesEncrypt(ASCIIEncoding.ASCII.GetBytes(text)); char[] chars = BitConverter.ToString(data).ToCharArray(); ArrayList al = new ArrayList(); for (int i = 0; i < chars.Length; i++) { if ((i + 1) % 3 == 0) continue; //BitConverter.ToString(...) returns data in the format XX-XX-XX -- this skips the dashes. al.Add(munge[Array.IndexOf(hex, chars[i])]); } return new string((char[])al.ToArray(typeof(char))); } public static string Decode(string text) { char[] chars = text.ToCharArray(); ArrayList al = new ArrayList(); for (int i = 0; i < chars.Length; i += 2) { al.Add((byte)(Array.IndexOf(munge, chars[i]) * 16 + Array.IndexOf(munge, chars[i + 1]))); } byte[] decrypted = DesDecrypt((byte[])al.ToArray(typeof(byte))); return ASCIIEncoding.ASCII.GetString(decrypted,0,decrypted.Length); } static byte[] DesEncrypt(byte[] data) { MemoryStream ms = new MemoryStream(4096); DES des = new DESCryptoServiceProvider() ; CryptoStream encStream = new CryptoStream(ms, des.CreateEncryptor(m_bDESKey, m_bDESIV), CryptoStreamMode.Write); encStream.Write(data,0,data.Length); encStream.FlushFinalBlock(); //calculate the length of the encrypted data byte[] bResult = new byte[ms.Position]; ms.Position = 0; ms.Read(bResult, 0, bResult.Length) ; encStream.Close(); return bResult; } static byte[] DesDecrypt ( byte[] data ) { MemoryStream ms = new MemoryStream(data.Length); DES des = new DESCryptoServiceProvider() ; CryptoStream encStream = new CryptoStream(ms, des.CreateDecryptor(m_bDESKey, m_bDESIV), CryptoStreamMode.Read); ms.Write(data,0,data.Length); ms.Position = 0; string strResult = new StreamReader(encStream).ReadToEnd(); encStream.Close(); return ASCIIEncoding.ASCII.GetBytes(strResult); } } // -- // Alan Samet // http://www.alansamet.com/ // http://www.htmlwindows.net/ // http://www.usfbs.com/ // http://www.marshwoodwinds.com/ Tag: System.Text.RegularExpressions Tag: 96146

    - Automate screen scraping: How to programmically "push" a Login button on another web page? I'm hoping to write a utility program that will navigate to another web site, logon with my username/password, and download data automatically on a schedule. When I use HttpWebRequest to get the initial logon screen, there are multiple embedded forms (Login, Forgot your Password, etc). I want to be able to pass my username/password information to the web page's login form and "push" the button (on their webpage, this is done through some javascript code). When I view the source code of this page, it appears that several hidden variables are set, so I imagine the I would need to get/accept/return cookies. I'm not sure how to "direct" the infomration to a page's particular "form" - in my case, "pushing" the Login button.

    - Any idea for create a combobox-like control I am combining a combobox-like control (named mycombo) with a textbox and a form (named comboform) in which there is a listbox with same size of form. The control mycombo has a method named dropdown in which mycombo show comboform and set its location beside the bottom of the textbox. I dont know what I do is a good idea or not. I mean the mycombo look like a real combobox. However, the MyCombo.form doesn't really belong to MyCombo.textbox or MyCombo, which is an indepedant control. When user click on another application to make the mainform which mycombo belong to deactive, the mycombo.textbox disappear with the mainform, but the mycombo.form just hang up there. Another example is, if the user drag the mainform to move from location A to location B, mycombo.textbox move together, but mycombo.form doesn't. I don't know how to make mycombo.form has a same behave with mycombo.textbox. Form control is the topest level control which cann't assign parent property.

    - Admin rights required for framework Installation ? I searched the archives and web and could not find a definitive answer. I am working on an installer (using Wise for Windows Installer) for the client piece of a client/server application. Question is: Will the clients need Admin Rights on their machines to install the .Net framework if it isn't already present on their machine? (My client app requires the .Net Framework 1.1 to run). Thanks in advance. Tag: System.Text.RegularExpressions Tag: 96121

    - displaying country name in current UI culture? I have a two-letter country code and I need to display the name of this country in the current UI culture. Sadly I can't create a CultureInfo and use the DisplayName property because this displays it in the localised version of the .NET framework and not in the current UI culture which I might have changed (it is calculated regardless of the language that the system is set to display). e.g: country code: US current ui culture: Spanish: test string i need: "Estados Unidos" Any suggestions?

    - Redistributing DIA dll problems Hi All I'm trying to distribute msdia80.dll (Debug Interface Access SDK) with my application. The problem is that regsvr32 generates the following error when I try and register the dll on the installation machine. "LoadLibrary ( "msdia80.dll" ) failed - This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." I have installed the .NET Framework Version 2 Redistributable Package on the installation machine as msdia80.dll has a dependency on msvcr80.dll. As far as I'm aware this should be all I need to do but obviously not. Can anyone help? Thanks in advance Tag: System.Text.RegularExpressions Tag: 96102

    - Problem faced while creating setup file for Pocket PC application I Created a Pocket PC application for iPAQ 5450. Every thing went fine even installer creation. I could run the setup and install it into the actual device and worked fine. The application enables syncronization with remote database using merge replication. I found contradictory results while installing the application. I will mention here all the steps that I done while creating and installing setups. Result: Case 1: worked fine. Case 2: show problem. Case 1: --------- Developing and installation site Details ------------------------------------------- Operating System 1. Windows 2000 server 2. Windows XP with SP2 Development Environment 1. Microsoft .NET 2003 2. Framework 1.1 with SP1 Backend 1. SQL Server 2000 Standard Edition 2. SQL CE 2.0 Communication Tool with Pocket PC 1. Microsoft Active Sync 3.8 Steps followed to create the Setup file 1. Created cab file for my application. 2. Included the cab file names in the INI file to install the cab file corresponding to the Pocket PC processor. 3. Created another INI file to include the names of the .NET Compact Framework cab(netcf.core.ppc3.x86.cab, netcf.core.ppc3.x86.cab, netcf.core.ppc3.x86.cab, netcf.core.ppc3.x86.cab) files to install .net compact framework corresponding to the Pocket PC processor. 4. Created another INI file to include the names of the SQL CE cab (sqlce.ppc3.mips.cab, sqlce.ppc3.sh3.cab, sqlce.ppc3.x86.cab, sqlce.ppc3.ARM.cab) files to install sql ce corresponding to the Pocket PC processor. 5. Created an Installer project to run CEAPPMGR while installing and uninstalling. 6. Created dll file from the Installer project. 7. Included new setup project to the solution. 8. Added Installer dll to the setup project. 9. Referred that dll in the install and uninstall process of custom action. 10. Added three INI files to our setup application to install .NET Compact Framework, SQL CE and my application. 11. Included all cab files to the setup project, which includes .NET Compact Framework, SQL CE and my application. 12. Build the Setup file. By doing so, setup installed everything (.NET Compact Framework, SQL CE and my application). I have tested this many times in my Pocket PC. Every time it installed successfully. Case 2. --------- Developing and installation site Details ------------------------------------------- Operating System 1. Windows 2003 server 2. Windows XP with SP2 Development Environment 1. Microsoft .NET 2003 2. Framework 1.1 with SP1 Backend 1. SQL Server 2000 Enterprise Edition 2. SQL CE 2.0 Communication Tool with Pocket PC 1. Microsoft Active Sync 3.8 Steps followed to create the Setup file I have followed all the steps in the Case 1 But in this case I failed to install the application to the Pocket PC along with Sql CE Cab and netcf cab. In 2003 server it is showing CEAPPMGR.EXE Application error. In Windows XP it is showing â??Send error reportâ??. Error produced in windows XP is in fact a contradictory one from CASE 1. But I tried with separate installation for each cab file. At that time it is working fine. But while installing along with any one of supporting cab files it shows error message. I tried this in different machines, but same error is throwing. I tried again in Windows 2000 server; it again failed to install the application so this again is contradictory result from Case 1. I have sent the error report to Microsoft using â??Send error reportâ?? option. I have searched a lot in the internet for a solution. Where could I have gone wrong?

    - Oracle Reference Cursors using Enterprise Library I have the trouble with the stored procedure returning ref cursor. I used the code provided by Horst. The Package ... ---------------------- CREATE OR REPLACE PACKAGE employee_main AS TYPE ref_cursor_type IS REF CURSOR; PROCEDURE get_employees (emp_cursor OUT ref_cursor_type); END employee_main; / CREATE OR REPLACE PACKAGE BODY employee_main AS PROCEDURE get_employees (emp_cursor OUT ref_cursor_type) IS BEGIN OPEN emp_cursor FOR SELECT * FROM employees; END get_employees; END employee_main; / The C# snippet which accesses the package... --------------------------------- public DataSet GetEmployeeData() { string pkgName = "employee_main.get_employees"; Database db=DatabaseFactory.CreateDatabase(); DBCommandWrapper cmdWrapper = db.GetStoredProcCommandWrapper(pkgName); cmdWrapper.AddOutParameter("emp_cursor", DbType.Object, 2000); return db.ExecuteDataSet(cmdWrapper); } Another procedure that updates the record with only IN and OUT parameters executes without problems. However as soon as I try to include parameter cmdWrapper.AddOutParameter("emp_cursor", DbType.Object, 2000); it gives me error on execution db.ExecuteDataSet(cmdWrapper): "ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of arguments in call to 'GET_VERSIONS'\nORA-06550: line 1, column 7:\nPL/SQL: Statement ignored\n" Help greatly appreciated.

    - overload several config files? Hi I am building a dotnet 1.1 app, in VB.net ... I would like to have several config files corresponding to multiple envirronment (Database, local Machine, Application, User...) and overloads each, in order to have, by the way, one config. So I would like to load a config file (app.config) at startup (as usual), then overload this file with a new file (came from SQL for exemple), then overload with a second file.....etc.... What do you think about that? is it possible? Do i must access to each file manually (with xml methods) ? read them and then construct one config file, and then load it? Thanks!!!!!! bye syl Tag: System.Text.RegularExpressions Tag: 96094

Hi,

I want to do the following:

"Pete jan jan john jan mark" --> "Pete B jan john jan mark"

So I would like to wite a RegEx that would replace the first occurence of
the matched string (in this case replacing "jan" by "B")
.replace replaces all occurences, but maybe a smart regex would solve that,
or let them find all occurences and use MatchEvaluator to only replace the
first and copy all the others back?
Any good Ideas?

Best Regards,

Jeroen Vandezande.

Jeroen,

The Replace method on the Regex object has an overloaded method that
allows you to specify how many times you want to perform the
replacement. That should allow you to limit the replacement to only
the first occurence.
