    - Need suggestions: integrated browser in Explorer I'm working on a team project that requires providing the capability to allow the user to browse for some non-filesystem-based data. In addition to that data, the application also supports opening filesystem-based data. Some on the team want to just create a new dialog for the non-filesystem-data that allows the user to browse, etc., providing similar behavior to the standard File Open dialog, and use the standard File Open dialog when browsing for filesystem-based data. There would be 2 menu options, something like File Open and Data Open. I think that it is bad design, and we end up re-creating a second dialog that looks and feels, for the most part, like the standard FO dialog. My idea is to create an Explorer plug-in that would basically allow for the navigation of our non-filesystem-based data through the embedded Explorer window in the File Open dialog -- seems much cleaner to me. However, I'm getting some push-back on the idea. Anyway, I'm posting here (maybe not the best, but a forum that I frequent) asking for suggestions or anything that demonstrates similar behavior so that I can take it to the group and hopefully come to the correct conclusion. Any suggestions? Thanks Tag: FileSystem.GetDirectories Tag: 117484

    - DataTable.ImportRow question Hi, I have a question about the .NET DataTable.ImportRow method. If I import a DataRow into an empty DataTable, will the empty DataTable pick up the schema of the DataRow I'm trying to put into it? For example, I have code that looks like this: DataTable tableWithData; DataTable emptyTable = new DataTable(); emptyTable.ImportRow(tableWithData.Rows[0]); If I call tableWithData.Columns.Count, I get 5. If I call emptyTable.Columns.Count before calling ImportRow, I get 0, which is what I expect from the DataTable constructor with no arguments... But when I call emptyTable.Columns.Count after calling ImportRow, I still get 0. And just to make sure that a DataRow is being imported, calling emptyTable.Rows.Count after the ImportRow statement gets me 1. Does anybody know if there's some way that I can programmatically import a DataTable's schema along with the data? Thanks. --Jay Tag: FileSystem.GetDirectories Tag: 117482

    - Best practice for sharing code between ASP and Winforms apps? Hi all, I've got a situation where I need to create a Windows Forms application as an admin tool which is driven by the same data as an ASP.NET application. Luckily my 3-tier-ish design means my data and business objects will cope quite well with this, but I'm wondering what the best way to do this is? I'm not sure I want both apps in the same folder, but I want some of my classes shared between the apps. Can anyone who's done this comment? Any articles I should read? Cheers, JC Tag: FileSystem.GetDirectories Tag: 117479

    - ASP.Net Framework 2.0 not showing up as an IIS property page I have installed (and un-installed, and reinstalled) framework 2.0 on a Windows 2003 server. I still cannot get the property page to come up on it. When I run aspnet_regiis -lv on the 1.1 framework folder, I get this: > C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322>aspnet_regiis -lv > 1.1.4322.0 Valid C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\asp > net_isapi.dll > 2.0.50727.0 Valid (Root) C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\as > pnet_isapi.dll > > C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322> I get identically the same thing when I run that same command from the v2.0.50727 folder as well. I know that I should get the property page when I have multiple versions of .net framework on this computer, but that property page is not showing up. Is there any way to fix this, to set which framework is going to be used on which website (there are multiple websites on this server)? Server is running Windows Server 2003, with all service packs & updates on it. It is also running sharepoint services (the small, condensed version, not the full-blown Sharepoint). That appears to work, too. The 1.1 framework website works, but not the one that is using Framework 2.0. Any help would be greatly appreciated!!! BC Tag: FileSystem.GetDirectories Tag: 117478

    - Case sensitive search in the combobox [.Net 2.0] Greetings! I am using a combobox bound to a list of items. The AutoCompleteMode is set to SuggestAppend and the AutoCompleteSource is set to ListItems. The list has items like \\lastname and \\LastName. The control's display and value member properties are set to the same field in the collection. If I start typing \\lastname, I do not see that in the suggested list and instead, I see a list of items starting with \\L. Is there a way I can have the list display the correct list?

I can access to all Methods, Properties but if I access to the structure (Called "InfoBlock") i´ll get the exception "Invalid access to memory location.".

    - Déployement compliqué...help! Bonjour, J'ai développé une dll (un objet COM plus précisément) sous Visual Studio 2005 et je dois l'installer sur un poste client ne possédant pas le framework 2.0. Le poste est en Windows XP SP2 tout simplément. Pour la faire fonctionner, je dois faire un "caspol" sur le répertoire de ma dll. Ensuite je dois l'enregistrer dans le GAC de windows (ma dll est signée bienentendu). Lorsque je fais un package .msi j'indique que je souhaite que le FrameWork soit installé sur la machine cliente s'il n'y ai pas déja. Mon soucis est le suivant : le framework que Microsoft me fournis est une version "lite" c'est le dot net fix de 22mo ne comprenant pas l'outils "gacutil.exe" entre autre et je ne peu donc pas enregistrer ma dll dans ce répertoire!!! Comment dois je faire?? installer le FrameWork SDK de 377mo sur chaque poste client??? Merci de vos réponses. David. Tag: FileSystem.GetDirectories Tag: 117462

    - Datagridview repositioning rows automatically Greetings! I am using a Datagridview bound to a custom collection [IBindingList] and it shows three columns- one is DataGridViewCheckBoxColumn and other two are DataGridViewTextBoxColumns. The list of the items is displayed in the datagridview and I start checking the DataGridViewCheckBoxCells. As I do so and scroll the list, the datagridview automatically switches the row position in the datagridview. The checkboxcell that I was trying to click is highlighted but is not checked and is not where my mouse pointer is positioned. This happens randomly and the application users are not really happy. In order to resolve this, I reset the SortedMode, tracked changes in CurrentCellDirtyStateChanged and CellValueChanged events but could not track the behavior. Has someone encountered this issue or someone direct me with some suggestions to resolve this problem? Thanks for your time. Regards, Raj Tag: FileSystem.GetDirectories Tag: 117461

    - Local Report with Object DataSource: BindingList in Table? Hi, I'm using VB.NET 2005 with a Local Report, and I used an Object as DataSource. The problem is: this Objects contains a Generic List (MyArticles, Inherist from BindingList), which contains other objects (Articles). I want a list of these Articles to appear in a table in my report, but I don't know how to do this. In the "Data Sources"-Window I can see the MyArticles-list, with the property's of the objects in it. But I can't drag and drop the List nor one of the Property's to the Report or a Table in the Report. Does anybody knows how I have to do this? Do I need to add the Article-object as a DataSource and change some things at runtime? Any help our hints would be really appreciated! A working sample would be great! :-) Thanks a lot in advance, Pieter Tag: FileSystem.GetDirectories Tag: 117450

    - Problem in IE automation upon Deployment Dear Sir I have a created a Web Service that uses ShDocVw.Dll and Microsoft.mshtml.dll for IE automation. For the development I am using VS 2005 installed on Windows 2000 Professional System. In my application, I use IE instance to navigate to certain site. This application runs fine on the VS Development server but when I deploy it on Windows 2003 server, my IE instance is unable to navigate to the specified page. However if I specify some local HTML file on Hard Drive it is able to read it. I have written the following code for creating IE instance and navigating. object Zero = 0; object Enmp = ""; ie = new SHDocVw.InternetExplorer(); ie.Navigate("http://www.website.com/default.htm", ref Zero, ref Enmp, ref Enmp, ref Enmp); //ie.Navigate(@"G:\Settings\LOG\23.htm", ref Zero, ref Enmp, ref Enmp, ref Enmp); while (ie.ReadyState != SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE) { } After running this code on Server I am getting "Open the www.website.com home page, and then look for links to the information you want. If you typed the page address in the Address bar, make sure that it is spelled correctly. If you still cannot open the page, click the Internet Explorer Search button to look for similar sites" as the content of IE HTML document. I have tried it several times by configuring IE setting and also by reducing the security settings and giving permissions to IIS worker process, but this error still persits. I think ,this seems to be configuration issue on the Windows 2003 server or could be some mistake in coding. If you could suggest anything that would be a great help to me.

    - Reference Set or Copy? I have a picturebox with an image loaded. I convert it into a bitmap, lock the bits, re-arrange the graphics, unlock the bits, and re-assign the bitmap to the image with: picturebox1->image = myBitmap; Everything works great! Question: Is the assignment statement above a copy function, or is picturebox1->image a reference to myBitmap? I know if I change the code as such: picturebox1->image = myBitmap; delete [] myBitmap; I get invalid object errors (implying picturebox1 is a reference). But, if I relock the bitmap, re-arrange the bits again, and unlock them without the re-assignment, the image never updates (even when I minimize/maximize to force a repaint) - implying picturebox1 has a copy of the data). So what exactly is going on here? (By the way, by using pictureboxes and lockbits/unlockbits, I can display & modify images without creating a graphics object or dealing with 'Paint' events - pretty cool!).

    - Setup file looking for wrong .NET framework. I had v1.0, v1.1 and v2.0 of .NET framework installed on my laptop and that was causing me a lot of grief. So I uninstalled v2.0 and pressed on with developing stuff in v1.0. Everything was great. I wrote a whole application. After completion I added a setup project. The setup project builds fine. But when I try to install the application, it gives me an error saying "This setup requires .NET framework." (Please install it). I checked the Windows Event Viewer and it shows the following error message which clearly shows that the setup file is trying to look for v2.0 of dotnet framework. How do I make it look for the correct version. Event Type: Error Event Source: .NET Runtime Event Category: None Event ID: 0 Date: 06/06/2006 Time: 3:32:02 PM User: N/A Computer: MIRSCP56579 Description: The description for Event ID ( 0 ) in Source ( .NET Runtime ) cannot be found.

    - Configuration problem depending on startup method Hi all, This is a little in-depth, so bear with me. I have a client application that uses the MS Config App block. Everything works as expected under normal circumstances and the ConfigManager is able to read items without problem when simply running the app. Here's the issue. We have also entered a registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\<MyAppName>\shell\open\command" that allows us to go to the IE address bar and type "MyAppName:<someargumentInfo>" and have it find our app. Problem is, when the application is started from this method, the Config Manager is unable to read any config data. It's confounding. My thought is that it's because the App starts out in the IE process, that the Framework isn't finding the App.Config file. When the App starts out in it's own process, all is good. Any ideas? Help! Thanks! Erik Blair Tag: FileSystem.GetDirectories Tag: 117379

    - windows app to retrieve data from asp.net I have an ASP.NET Web App that generating some files in realtime and it does a bunch of other processing stuff. The user then will launch a desktop Windows App to print the files that were generated from the ASP.NET Web App. According to my research I have to either use activex or there is not way to automatically download some files from the Web App to the user local machine. (I'm told Activex is out of the question.) I then decided to pull the files from the server. I've used the WebClient and there is a DownloadFile method which allows me to download files from the server to the local machine programmatically without user interaction. However, the file name is dynamic and generated in realtime. Is there a way that I can at least transfer or pass a string or variable from the ASP.NET to the Windows App or vice versa? Any suggestions is welcome. I really need a solution quick. Thank you! Tag: FileSystem.GetDirectories Tag: 117378

    - Hi, how do I create a partial trusted sandbox of an embedded scripting Hi, I'd love to enable the writing of custom scripts by users. The main purpose is to do smart merge tags for a mail merge. Each such smart merge subroutine will add an additional dimension in transforming the looked-up substitution value. For example, one such sub routine would derive a suitable default naturalized salutation in Spanish when the looked-up value is a DBNull. It would be nice to cache and host the scripting engine and serve the execution via web services. The web service would take script snippets matching a certain call signature. Verify it * doesn't try to get out of the sandbox; * makes use of a small selection of safe libraries; * enjoys completion within a certain amount of time, free of infinite loops The web service would then pre-compile the snippet and cache it for calling on the fly. Script updates would prompt recompiles. The web service will then field directives to call these subroutines. These web service calls will provide the parameter values. The web service is then responsible for loading the embedded scripting engine environment, calling the script, and then returning the value. The web service may cache the scripting environment to eliminate unnecessary initialization. I have been made aware that we should investigate CRL concepts such as AppDomains with partial trust domains. And to study recent articles embedding IronPython into MDbg. But has anyone had to do something like this? With IronPython or another scripting language engine? Any help or assistance would be greatly appreciated, thank you ahead of time!

    - Click Once - Additional actions on file download Hello all. I have an application that will be deployed remotely on tablet pc's. It uses SQL Server Express for storing it's data. I am planning on deploying the application using click once but I need to make sure first that it provides me with certain features I cannot live without: I need to be notified every time a new application file is downloaded so that I can perform some custom actions. For example, I keep the database schema definition in an xml file. Whenever the schema changes, a new xml file will be distributed to the clients. When this file is downloaded by a client, it must be provided to a SchemaUpdater class which will handle the uprade of the database schema. There seems to be no events under the System.Deployment.Application that provides this kind of detailed information. Tag: FileSystem.GetDirectories Tag: 117373

    - hosting controls in IE, best practice for disposing of memory? Hi, I'm currently looking into an issue I've noticed with the .Net framework and hosting controls in IE. We have a webpage which has 2 frames, the topbar frame hosts a .Net control that acts as a client and talks to a server. The bottom frame hosts various java views and some .Net views to display the information in the client control. I noticed whilst debugging that when the page is moved from one view(control) to another the old one is still running in memory, in the background, I saw this by some debug traces that were still in the code. it appears that when the page changes it doesn't actually dispose of the controls but just disposes of their Handles. Thus all arrays of data etc stored in them sit there gobbling memory. Take for instance, initially IExplore process before a "view" is loaded consumes approx 40mb with the topbar .Net client loaded... I then load up one of my biggest controls/views and this jumps to around 85mb, I then switch to a java view, which is another webpage, and it drops to about 83mb... hardly any memory recovered what so ever... Once I realised this was happening I overrode OnHandleDestroyed and cleared out my arrays, and regained a lot of the memory, down from 85mb to about 60mb... So my question is, is there some documentation somewhere about this? Best practise for disposing of .Net controls hosted in IE, as they consume memory when really they should be disposed and the garbage collector (or whatever it's called in .Net) be regaining almost all the memory.

This button adds the value of the text box to the session state and then forwards the user to the search page. The search page inserts this value into the text attribute of another text box and runs a site search against the MS index service based on the text of this second text box on the webserver and populate a datagrid with a template column with the results. This is, I think, a fairly standard site search scenario. When doing one or two searches from the header, everything functions fine. After the third or fourth time though, I get the famous "Invalid postback or callback argument" error message. I have tried turning eventvalidation off in the web.config, although I would rather keep it on. I also tried manually registering the buttons for eventvalidation in the render methods of the pages. Nothing has seemed to work. Any help would be appreciated. Thanks, Matt Tag: FileSystem.GetDirectories Tag: 117369

    - Issue with multiple GUI threads on .NET 1.1 Hello! I am writing a desktop application that uses multiple GUI threads to interact with the user. Secondary GUI thread creates a main form for this thread, having application's main form as its parent and calls System.Windows.Forms.Application.Run() with this newly created form. The problem is that, under certain conditions (described below) secondary GUI thread strangely crashes after it has exited the 'threadstart' function. The crash is 'Unhandled access violation exception' (0xc000000a) in ntdll.dll with the following call stack: ntdll.dll!_RtlFreeThreadActivationContextStack@0() + 0x1eda4 kernel32.dll!_ExitThread@4() + 0x39 kernel32.dll!_BaseThreadStart@8() + 0x3d My environment is .NET 1.1, Microsoft Windows XP SP2. Condition for crash is that thread crashes only after I create and display a modal dialog box (another custom form), heaving main form for GUI thread #2 as Parent. This dialog box is used to display messages to the user instead of System.Windows.Forms.MessageBox (it has enhanced functionality like "Don't show this anymore" checkbox and timeout timer allowing it to be dismissed if user haven't clicked any buttons. When I switch back to System.Windows.Forms.MessageBox everything is fine. As this issue occurs in a big solution, I created new simple little CrashTest Project to isolate and simulate this behavior, but so far I haven't succeeded. Does anyone know what could cause this behaviour? Best regards, Alexei N. Adadurov (alexei.adadurov at super-lab dot ru) Tag: FileSystem.GetDirectories Tag: 117367

    - Enterprise Service Launch and Access Permissions Hi, How can I grand Launch and Access permissions only to several users or groups of my .NET Enterprise Services Server Application (DllHost)? I understand that COM+ uses DCOM security mechanisms, and that DCOM is actually checks Access and Launch permissions. But unfortunately, I can't see my Application under the DCOM MMC, only under the COM+ one. Thanks Tag: FileSystem.GetDirectories Tag: 117365

    - System.DirectoryServices and WinNT provider I am trying to clean up the remnants of an old NT4 domain and am trying to create a DirectoryEntry object referring to an NT4 group via the WinNT provider. That part works fine, but I cannot find a way to get the membership of the group. The same kind of operation works fine on members of an AD group via the AD LDAP provider. Anyone know how I might get NT4 group members without using Interop? Trevor Tag: FileSystem.GetDirectories Tag: 117361

    - Unable to get service to install automatically with custom actions I have not been able to determine why my installer package will not execute the custom actions that create the windows service when my service is installed. I even stuck a service notification message in the ProjectInstaller code and see nothing to indicate it is being executed. For my development environment I am using Visual Studio 2003 with the .Net Framework 1.1. I on Windows XP Professional. I currently have all Windows patches installed except for the .Net 2.0 framework. If I compile the service and manually run InstallUtil then the service is created and can be run successfully. That's how I tested the service. This does NOT seem to utilize the ProjectInstaller class within the executable; it works with or without this code. If I run the msi from the compiled installation project then the program itself is installed but, as far as I can tell, there is no attempt to register the service. There is only one service in the project. I created the ProjectInstaller.cs for my service and it has everything I would expect to be there including adding the ServiceProcessInstaller and ServiceInstaller to the Installers object. Each of the 4 tasks in the Custom Actions points to the primary output of the service. Each has the InstallerClass property set to True. I noticed that each of the custom actions actually uses the obj directory for the source instead of the bin directory but I don't know if this is normal. The service executable has the startup object set to the entry point. There is a file called servicename.InstallState in the install directory after the install that I don't recall seeing in past projects. It has SOAP code in it. Is there anything else I can check or anything that could cause this behavior? Thanks for any assistance, Bill Faulk Tag: FileSystem.GetDirectories Tag: 117359

    - Form resource files Hi there. I apolgize for posting this again (from June 2nd) but I've been researching for many days now with no success. I have an app that will be reading arbitrary ".resx" or "resources" files passed on the command line for instance. Given only a resource file IOW, does anyone know: 1) How the app can determine if the passed resource file contains (localized) form resources (i.e., it stores a form) 2) If it does contain (localized) form resources, how can I then generate that form dynamically Note that the native .NET utility "Winres.exe" is able to do this but I can't figure out how (not without using techniques that appear to be undocumented). Any help would be greatly appreciated. Thanks. Tag: FileSystem.GetDirectories Tag: 117342

Does anyone know in what order the directories will be returned? (i.e.
alphabetically or in date order)

Thanks

Regardless of which way they are currently returned, I wouldn't create a
mission critical application that depended on that order. I would recommend
that you get them as they come and then worry about sorting them later. Even
if it works now, MSFT could easily change the sort order in a future OS/Framework
version as they did with reflection between 1.1 and 2.0. (see http://devauthority.com/blogs/jwooley/archive/2005/11/02/597.aspx)
