    - setting envrionment variable in C# and access it within native C++ We are having difficulties getting environment variable within native DLL written in C++ which is loaded by C# .NET assembly, the env var is set by the .NET assembly. We have an existing C++ application, and want to access it within C#. So we wrote Managed C++ wrapper which access the native C++ DLL. The Managed C++ wrapper is compiled as .NET assembly that C# can access. The native C++ DLL need to have an environment variable set to work properly. So within the C#, we use: [DllImport("Kernel32.dll")] public static extern int SetEnvironmentVariable( string name , string value ); to set the env var. But within the native C++ DLL, it will fail when trying to do "getenv()", with error: Object reference not set to an instance of an object. 1. If we make the C# application as console application and set env var in the console before start the C# application, it works. But we can't make the C# app a console app. 2. If we execute within the C# application a .bat file which prints out the env var, it shows that the env var is set. Looks that the native C++ DLL can't getenv() on the env var set within the C# app. Any solutions for this? Thanks a lot. Tag: How to add right click menu Tag: 108605

    - ASP Windows Service or Console based application Hi all, I am confused as to what kind of application to develop. I have to create an application thats like a "Engine" which continously monitors a DB or whatever. It has to work even if the user logoff as this engine feeds some other application. I tried creating a Windows service that runs continously but the status shows "Starting" and i cant "Stop" or "Pause" and was suggested by one BravesCharm that "Status does not change as the service never notifies the SCM that everything started OK" which makes sense. Is there a way for windows service to start some other application? is yes then how can i stop it from this windows service? Please do give me suggestions on how to achieve this. Thanks, Stephen Tag: How to add right click menu Tag: 108601

    - Clickonce install from CD Hi, I generated the deployment files into a local directory with specified installation URL. My prolbems: - If there is an internet connection on the client machine, it skips the files on the local hard drive, immediately start downloading from the web. - if there is no internet connection, the setup.exe fails (which is the startup program from a CD), but the application icon installs the software well. I implemented a custom async update. When I call the CheckUpdateAsync method I have got an exception in the Application.ThreadException event, not in the AsyncCompleted event as the MSDN says (in the e.Error)... Why? Thanks. lelez ------------ Here it is the code: try { ApplicationDeployment dep = ApplicationDeployment.CurrentDeployment; dep.CheckForUpdateCompleted += checkHandler; dep.CheckForUpdateAsync(); } catch (System.Net.WebException) { // never runs! System.Windows.Forms.MessageBox.Show("There is no internet connection."); } catch (Exception ex) { xxxx.Common.Util.Logger.LogException(ex); } Here it is the handler: private static void dep_CheckCompleted(object sender, CheckForUpdateCompletedEventArgs e) { if (e.Error is System.Net.WebException) { System.Windows.Forms.MessageBox.Show("There is no internet connection."); return; } ApplicationDeployment dep = ApplicationDeployment.CurrentDeployment; dep.CheckForUpdateCompleted -= checkHandler; try { if (e.UpdateAvailable) { ContinueQuestionEventArgs ce = new ContinueQuestionEventArgs(e.AvailableVersion.ToString()); // Ask the user about continue... if (updateIsAvailable != null) updateIsAvailable(null, ce); if (ce.Continue) { dep.UpdateCompleted += updateHandler; dep.UpdateAsync(); } } } catch(InvalidOperationException ex) { xxxxx.Common.Util.Logger.LogException(ex); } } // dep_CheckCompleted... -- ----------------------------------- http://www.lelez.hu ICQ: 177465172 Tag: How to add right click menu Tag: 108600

    - Caching architecture question. I am thinking about using Caching application block in my web application, for the performance reasons. My ideal sitiuation would be if i could plug in the application block between my Persistence layer and database, so that objects are created from the cache and cost of CRUd operation can be avoided.... the problem each object is not having a unique key, and caching application block does not provides any typed cache functionality, for example if i store a product object wtih uid 1 and a customer object with uid 1 then it would overwrite the product object, Iam thinking about creating a multiple cache managers according to the type of object, and keep all those cache managers in a super cache... in that case would the scavenger clean up caches inside a cachemanager object ? any comments Tag: How to add right click menu Tag: 108595

    - GDI leaks? Hello all, I've just found the issue that really scares me. It seems that ListView doesn't release some GDI objects. Here you are steps to reproduce the problem: 1. Run Task Manager 2. View->Select Columns 3. Check "GDI Objects", press OK 4. Run Visual Studio 2k3 5. Create new Window Forms application 6. Put into the form "ListView" and enter 5 items. 7. Run Application 8. Force application to refresh (e.g. move another window above this application) You will see that GDI objects increase really fast. The same situation with Add/Remove items, GDI objects still increas. I've noticed that I can increase it number even till 10k and after that application starts to glitch. It seems that the problem can be solved after: GC.Colelct(); But this is *really* bad solution which significant impacts to the performance of application. Any ideas?

    - RegionInfo.ThreeLetterISORegionName returns TwoLetterIsoCode for B Hi all, I need to get the ISO-3166 code for BOSNIA AND HERZEGOVINA. What I am trying is 1) RegionInfo ri = new RegionInfo(5146); ==> works fine and gets RegionInfo 2) ri.ThreeLetterISORegionName ==> Output "BA". Expected "BIH". But I only get "BA" - not "BIH". Any help greatly appreciated I have noticed that BA/BIH is not listed in http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemglobalizationregioninfoclasstopic.asp Might this be the problem? I have also read about synthetic cultures http://blogs.msdn.com/shawnste/archive/2005/12/06/500675.aspx But anyway, BIH is a valid code found in ISO-3166. Any ideas how to get it via RegionInfo?

    - Dynamically import fusion.dll I'd like to dynamically import methods from the fusion library (fusion.dll). However, if I just do a straight [DllImport(blah)], I can't guarantee that I get the .Net 2 runtime version. I've found that the unmanaged method LoadLibraryShim in mscoree.dll will return a module handle to the latest runtime version, the thing I can't figure out is how to then use this handle to invoke methods on the library from C#.

    - automatic Time conversion ? Hello all, I am writting a client application that asks a DataSet from a server (WebService) and displays it locally in a DataGridView. The DataSet has a DateTime column. The problem is that the server and the client work in different time zones, and somewhere in the client the time conversion is made (added / substracted 1 hour). So in my grid I see different hours. How can I stop that ? Basically, I need to ignore this diference, but I can't find a way. Please help. Tag: How to add right click menu Tag: 108577

    - Hidden Attribute on file affects security? Hi --- I tried to write an application that uses a config file. When I set the Hidden attribute on the config file, I found that my application was no longer able to write (System.IO.File.WriteAllText as well as System.IO.File.StreamWriter), and also not able to delete (System.IO.File.Delete), the file. I get an access denied error. However my application can remove the Hidden attribute, after which writing and deleting work properly. Is this expected behavior? If so, can someone point me to the documentation that explains the relationship between hiddenness and file access? thanks, denise Tag: How to add right click menu Tag: 108563

    - Does Framework 2.0 trash COM for everyone else ? We are running Server 2003 for our critical server applications. We have been updating a number of core software pieces to VS2005 / Framework 2.0. This software is installed and pretty much working as it should. The PERPLEXING issue to me is that I have antique VB6 COM components that are failing after adding Framework 2.0 to this server. Usually when the component is done after a lengthy process, and is returning to the caller. The VB6 component seems to have completed successfully, but the exception "Object variable or With block variable not set" is being thrown to the calling script. I have a VB6 test application which invokes the same VB6 COM component, and it also fails with the same error, at this server. We are talking about software that has been in there doing its job for years. Wanting to see it fail first hand I ran the test application on a development computer, W2K, and it of course runs fine. Besides a few isolated and unrelated VS2005 applications of our own, the only thing new on this computer is Framework 2.0 redistributable installation. I have to be suspicious that this has some how trashed COM for others. Tag: How to add right click menu Tag: 108557

    - cookie problem Greetings... I need desperate help with my problem. I guess the solution is related in some way with the cookies getting lost in the authentication process working with some web servers. Appreciate any help you could provide. I've created an application that does the authentication process using forms. I've succeed to install it in a lot of web servers and it works perfect. But, and here is the problem, in some of the web servers this is what happens: Starting the application the user has to follow the authentication process. If the user fails to enter the password, the server communicates him that either the password or the user name is incorrect. At this point, the process works fine. The problem starts when the user follow the authentication process correctly (user name and password are correct), after this, the system fails to continue to the next page, the user is sent back to the authentication page (like he was trying to violate the security using the URL). This problem happens when a user is trying to do the authentication process in a client machine; it doesn't happen if the user is in the server machine. I've done some research and these are the results: As the application works fine in most of the servers I've installed it, it shouldn't be an application problem. As the application gives the user an answer when either the user name or the password is incorrect, the server is responding correctly. As the application works fine if the user is in the server machine, installation or database problems are discarded. I've been tracking the cookies and this is what happens: If the user is working directly on the server machine, the system creates the cookies and everything works fine. But, if the user is working on any client machine the cookie never arrives. The problem is not on the client machines as if I connect them to another server, the cookie is created and the application works fine. The user is redirected to the authentication page because the cookie gets lost (Again: The client machines works fine connected to other servers) and he loses his credentials. Searching through the web I've found that there is a problem with the server name when it has characters like "_", but this is not my case. I've tried names like: Server/MyApp/Authentication.aspx 192.168.1.100/MyApp/Authentication.aspx OtherName/MyApp/Authenticacion.aspx But none of them works. I hope I've been clear enough with my explanation. Thanks in advance for any help you can give me. PD: The application has been developed using C# in VS .NET.

    - SMTP and CDO.Message Object error This is a multi-part message in MIME format. ------=_NextPart_000_0011_01C60176.1A6EDE40 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable In my Win app I found that using the SMTP object doesn't release = resources after closing the application. During testing I have to open = and close the app many times and I found that after about three times it = locks up when I call the Send() method and returns the error "Could not = access CDO.Message Object". I found that if I create a new Win App and = copy and paste the code into it, then it runs fine for the first couple = of times and then starts returning that error.

    - Stopping toolbars from dragging onto other specific toolstrip containers Hi, Ive got 2 toolstrip containers on a page, the first should allow the user to move a toolbar onto any of the 4 sides of the form, the 2nd container should only allow the user to move the toolbar left or right on the form (without detaching and re-attaching to another toolbar). Is there an easy way of doing this? Tag: How to add right click menu Tag: 108522

    - Remoting between 2.0 and 1.1 Hi everybody, I have a 3rd party 1.1 framework dll that I want to use in a .net 2.0 application. Alvin Bruney already told me here that I can't use it as a reference in my 2.0 app because it will be run in 2.0. So, I'm wondering if it's possible to make a little 1.1 app that will reference that dll and then it will communicate with my 2.0 app using remoting. Will that work? -- Hugo Vale www.datastreamcs.com Tag: How to add right click menu Tag: 108519

    - Removing the navigation sound in Web browser Hello, since .Net Framework 2.0, it's now possible to use the built-in Web browser component. I migrated my software to use it without any problem. I don't use the browser for opening URL but instead I simply generate the HTML content that I assign to the component using the WebBrowser.DocumentText method. I have only one problem left : each time I update the page content with the above method, I get the "click" sound that IE produces when a new page is refreshing. I couldn't find any properties to turn sound OFF. Is there a work-around to make sure the browser doesn't make a sound? Thanks, Neb Tag: How to add right click menu Tag: 108517

    - Cannot instantiate EnvDTE.DTEClass class Hello, I am currently developing an add-in for Visual Studio .NET 7.0, 7.1 and 8.0. I am using Visual Studio .NET 2003 to develop it and C# as a programming language. I have installed Microsoft .NET framework 1.0, 1.0 and 2.0 on my machine. Normally, my add-in registers his own commands, bound to UI command bar buttons. To perform a clean uninstall, I added an Installer class, in whose Uninstall method I am trying to delete the commands, registered by my add-in. But in this Installer class I don't have a valid instance of DTE object, so I have to create it. The class which represents the Visual Studio .NET IDE is EnvDTE.DTEClass class. Unfortunately, when I am trying to instantiate it, I get the following exception: System.Runtime.InteropServices.COMException (0x80040154): COM object with CLSID {3C9CFE1E-389F-4118-9FAD-365385190329} is either not valid or not registered. Now, I checked whether there is a such COM server with CLSID {3C9CFE1E-389F-4118-9FAD-365385190329} registered in HKEY_CLASSES_ROOT\CLSID (that is there is a well-formed key under HKEY_CLASSES_ROOT\CLSID\{3C9CFE1E-389F-4118-9FAD-365385190329} having the required InprocServer32 subkey, pointing to: EnvDTE, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a I also created a standalone Windows forms application that actually tries to create a new instance of DTEClass class, but still I have the same exception. That is to show that this error is not caused by Windows Installer or something - this is obviously a generic error. I found an article in Internet about the same problem, but still it hasn't any prescribed solution for it. Does anyone has an idea how I can solve this issue?

    - Code only executes on Step Through I am using VS 2005, VB.Net. I need to connect to an FTP server and get a list of files. I plundered the following code from MSDN to accomplish this task. It was part of a class called clsFTP: Public Function GetFileList(ByVal sMask As String) As String() Dim cSocket As Socket Dim bytes As Int32 Dim seperator As Char = ControlChars.Lf Dim mess() As String m_sMes = "" 'Check if you are logged on to the FTP server. If (Not (m_bLoggedIn)) Then Login() End If cSocket = CreateDataSocket() 'Send an FTP command, SendCommand("NLST " & sMask) If (Not (m_iRetValue = 150 Or m_iRetValue = 125)) Then MessageString = m_sReply Throw New IOException(m_sReply.Substring(4)) End If m_sMes = "" Do While (True) Array.Clear(m_aBuffer, 0, m_aBuffer.Length) bytes = cSocket.Receive(m_aBuffer, m_aBuffer.Length, 0) m_sMes += ASCII.GetString(m_aBuffer, 0, bytes) ' Console.WriteLine(m_sMes) If (bytes < m_aBuffer.Length) Then Exit Do End If Loop mess = m_sMes.Split(seperator) cSocket.Close() ReadReply() If (m_iRetValue <> 226) Then MessageString = m_sReply Throw New IOException(m_sReply.Substring(4)) End If Return mess End Function I connect to the FTP server perfectly. The rest of the functions in that class work great, such as download, upload, etc.. Sadly, GetFileList only returns the first file unless I step through, then it returns everything I have. If I put a break point at the Do While line, then run again, it executes perfectly. If I let it run, it gives me just the first file. The mask I am using is also correct. Any clues??? It is driving me insane. Does the code look tight? I have tried everything I know how. Thanks, Mike Tag: How to add right click menu Tag: 108513

    - Relative URI parsing I'm trying to test some functionality regarding relative URI's with the Uri class in .NET 1.1 and hitting problems. The Uri class can only hold absolute URIs, so there's a constructor that takes a URI and a string which is the relative address. However, some of the normative examples given in RFC 3986 (http://www.gbiv.com/protocols/uri/rfc/rfc3986.html) don't seem to be handled by the class or give incorrect results. For example, given a base address of http://a/b/c/d;p?q, the failing normative examples are as follows... "g:h" = "g:h" => System.UriFormatException : Invalid URI: The format of the URI could not be determined "//g" = "http://g" => http://g/ - Note trailing / "#s" = http://a/b/c/d;p?q#s => http://a/b/c/d;p#s "../../../g" = http://a/g => http://a/../g "../../../../g" = http://a/g => http://a/../../g "/../g" = "http://a/g" => http://a/../g Is this expected behaviour?

    - Database Dependancy Issue I have a very unusual problem which I would really appreciate some help with, if anyone has come across something similar before. Essentially we have three servers, a web server and two database servers. There are several applications running on the web server and the databases for each are distributed across the two servers. To even the load it is necessary to move the database for one of the applications to the other database server. So, Database Server A currently hosts the database Database Server B is where the database should be moved to The following steps were taken: 1) Detach database on Server A 2) Copy database MDF and LDF files to Server B 3) Re-Attach database on Server A in case rollback is required 3) Attach database on Server B 4) Change application to point at Server B 5) Test application - everything seems fine - can see data appearing in Server B 6) Detach database from Server A ** The web application is now no longer able to connect to Server B. ** The following steps were then taken: 1) Reboot all three servers 2) Check that the connection string is definitely set in only one place in the application The web application is still unable to connect to Server B. In a further peculiarity, as well as the Web Application there is also a Windows service which accesses the same database. This is able to connect to Server B fine, with or without the database on Server A being attached. Many thanks in advance Lewis Tag: How to add right click menu Tag: 108508

    - News Analysis: Java? It's So Nineties DECEMBER 13, 2005 . Editions: N. America | Europe | Asia | Edition Preference News Analysis By Steve Hamm Source: http://www.businessweek.com/technology/content/dec2005/tc20051213_042973.htm Peter Yared, CEO of software maker ActiveGrid, spent a critical chapter of his career steeped in Java, the programming language developed by Sun Microsystems (SUNW). In the late 1990s, Yared was chief technology officer of NetDynamics, which pioneered an application server designed to boost the performance of Web sites. It was based squarely on then wildly popular Java. He went on to spend five years as an executive at Sun. So it's especially surprising that Yared holds this view: "Java is a dinosaur." But Yared has good reason for thinking that way. His two-year-old company sells what he calls a "next generation" application server, used to build Web sites and corporate applications, that doesn't rely on Java. Instead, it's tied to open-source software packages, including the Linux operating system, the Apache Web server, the MySQL database, and a collection of so-called scripting languages that all start with the letter P -- Perl, Python, and PHP. Hence the acronym LAMP. LIGHTING THE LAMP. Yared says developers far and wide are creating a new generation of Internet-based applications with LAMP and related technologies rather than with Java. Can it possibly be that Java -- once the hippest of hip software -- has become a legacy technology, as old and out of style as IBM's (IBM) mainframe computers and SAP's corporate applications? Mounting evidence points to yes. Reports by Evans Data Corp., which does annual surveys of the activities of software developers, show Java use is slipping as LAMP and Microsoft's (MSFT) .NET technology gain traction. In North America, the percentage of developers who use Java as one of their principal programming languages declined to 47.9 in Evans' fall survey, vs. 51.4% in the fall of 2002. The same surveys show that while Java use is climbing in Asia, it's on the decline in Europe. Meanwhile, .NET usage increased to 54.1% from 40.3% in the same period in North America, and exceeded Java use in Europe and Asia. In a different survey series, the use of PHP in North America grew to 36.1% this fall, from 26% in the fall of 2003. It grew almost as quickly in Europe and Asia. "There's more competition out there," says Evans President John Andrews. "These other technologies are catching hold. They're biting away at [Java's] share." "I VEHEMENTLY DISAGREE." Another indicator of possible Java decline comes from shifts in the popularity of books being bought by developers. According to O'Reilly Media, the leading independent publisher of books for programmers, sales of Java-related books are off 4% so far this year, while sales of books related to AJAX, a new Web site-building formula used predominantly with open-source software packages, are up 68%. Java book sales are still much larger, however. Sun is adamant that Java isn't losing momentum. "I vehemently disagree," says John Loiacono, executive vice-president of Sun's software division. "Is Java at the end of life? We think Java is just kicking in." He points to the continued strength of Java as a mainstay of large, complex corporate applications, as well as the popularity of Java in cell phones, where 600 individual models run Java, and seven of the top 10 mobile games are based on the technology. Even as Java holds its own in key areas, interviews with more than a dozen tech industry players and analysts indicate the landscape is shifting in ways that disadvantage Java. That carries serious implications not only for Sun but companies including IBM, BEA Systems (BEAS), and jBoss, which have made huge bets on Java. If Java's luster dims, so does the appeal of products based on the language. And that creates inroads for competitors such as Microsoft and the non-Java faction of the open-source crowd. NEW PROGRAM. Here's a look at a few of the seismic shifts underway. For one, many of the now-large companies built from the ground up to operate on the Internet don't make Java a major piece of their tech strategy. Those include Google (GOOG) and Yahoo! (YHOO). The new generation of lighter-weight programming tools, including AJAX and PHP, are immensely popular with the Web 2.0 startups, including the likes of Friendster, Flickr, and Facebook. The new tools allow programmers with less training to build applications rapidly. Browser pioneer Marc Andreessen, chairman of Zend, a PHP company, says the shift is like the one in the 1990s from traditional programming languages C and C+ to Java. "We're seeing it now with a big migration from Java to PHP in Web development," he says. Stats back him up. The number of Web sites using PHP has risen to 23 million today from zero in 2000, according to surveys by the Internet analysis firm Netcraft. When Java emerged in the mid-1990s, it was seen as a potential antidote to Microsoft's hegemony. Using Java, software programmers and Web site developers could write a program once and run it on a wide variety of computer operating systems. Java failed to make a dent in Microsoft's desktop Windows monopoly, but it became a powerful force in the world of server computers, used for running large corporate applications and Web sites. CORPORATE CONNECTION. So far, Java retains its stronghold in corporations -- even among heavy open-source software users. Red Hat (RHAT), the leading distributor of Linux software, recently created support programs for three separate groupings of Linux and related software. One is for simple Web sites and Web applications, and doesn't include Java. But the two other groupings, for more sophisticated Web sites and enterprise applications, have Java. "If you want to do more sophisticated things, you've got to have Java in it," says Tim Yeaton, senior vice-president for marketing at Red Hat. But even in corporations, Java can't rest on its laurels. "You see that technology migrates from hackers to innovative users and eventually to the mainstream," says Tim O'Reilly, founder and CEO of O'Reilly Media. The situation at Merrill Lynch & Co. (MER) in New York is telling. The investment bank runs many of its newer math-heavy applications -- such as options, futures, and derivatives -- using just Linux and the Apache server. These technologies are superior to Java in computational applications, says Andy Brown, chief technology architect at Merrill Lynch. "It's closer to the metal," he says. "When you write code on Linux there are less layers. You don't need Java for it." When it comes to writing new desktop applications for traders and salespeople, many are written with Microsoft's Visual Studio .NET programming tools. "It's very fast to develop," Brown says. A WIDER .NET. Microsoft, which recently released an update of its .NET technology, says it's seeing gains across the board -- in large companies and from small, complex applications to simple ones. Market research backs it up. An October report by IDC shows that 35.7% of large corporations surveyed said they use .NET for their most important applications, compared with 25.3% for Java. An earlier Jupiter Research report showed that 62% of midsize businesses have adopted .NET, vs. 36% for IBM's WebSphere technology, which is based on Java. Microsoft expects Java to gradually become less and less important for corporations. "The future of Java is to become an underlying programming framework that nobody makes any money on," says John Montgomery, a director in Microsoft's developer division. "It becomes a commodity." Montgomery acknowledges that Microsoft hasn't done well with the Web 2.0 set, but he expects that to change. It has released a test version of server software that enables Web developers to easily use AJAX on top of Windows. CLOSE RACE. Sun acknowledges that .NET is picking up steam in corporations. "There will be more than one language out there," says Sun's Loiacono. "Plus, it's Microsoft. They'll be a player." Still, he believes Java and .NET are essentially in a dead heat and denies that .NET has pulled out into the lead. Sun, IBM, and other members of the Java community are steadily adding capabilities to the software, though at a slower pace than during its go-go years. At the same time, Sun has offered open-source versions of its Solaris operating system and related software packages as competition to LAMP. IBM stands by its commitment to Java. Its WebSphere middleware is a multibillion-dollar business that grew 14% last quarter. Big Blue believes Java will remain a vital piece of technology for corporations. But when it comes to the dot-com world, IBM is hedging its bets. Earlier this year, it threw its weight behind PHP as a Web programming language. "The culture at IBM isn't to get enamored with one technology," says Rod Smith, vice-president for emerging software technologies at IBM. "People want to do different things. We say, 'We can do that.'" And to Java's possible detriment, so do a rising number of other developers. Tag: How to add right click menu Tag: 108488

The situation is this, if the application is to be used by say user from another country, they have their own local time and Time Zone Info, and their own system (server) time. I like these to be configurable. I know that to change timezone I need a class and method inside the System.Globalization. Can you help narrow it down or pinpoint it for setting and getting time zone? Also, how to get a list of Time Zone to be displayed in a Combo Box? Is there a method for this?

When I use .Connect, I get the expected SocketException 10061 No connection could be made because the target machine actively refused it. Now, when I use .BeginConnect / .EndConnect no exception is thrown on .EndConnect and the code continues. I get an error on .BeginReceive telling me the Socket is not connected. If I try the .BeginConnect / .EndConnect a second time, I do get the expected 10061 ErrorCode. This behaves the same in .NET 1.1 and 2.0. Am I missing something or is there a reason why the first .EndConnect does not throw an exception like I expect it to? Thanks, Mike Tag: How to add right click menu Tag: 108477

Tool: Visual Studio 2005

I have a custom photo library application previously written in VS 6.
Basically it has
1) DriveListBox, DirListBox, FileListBox, all listed as
Microsof.VisualBasic.Compatibility.xxx
2) PictureBox inside a Panel (for auto showing scroll bars when photo
exceeds viewable area).
3) Buttons under FileListBox to Rename, Delete, etc file.

I'm thinking there must be something equivalent to Explorer that allows
you to single click to rename, right click with a bunch of options
(Rename, Delete, Cut, Paste, etc) that I can replace the FileListBox
with. If not, then I'd like to make it so that right click on a
selected file would prompt a context menu with a few basic options.

Thanks.
