    - Getting CD-ROM & DVD Drives Infomation... I am looking for a way to get information about all CD-ROM/DVD Drives on system & tell difference between CD-ROM/DVD drives & their ROM/R/RW Media & check if media is in the drive...

    - How to securely publish a Click Once application I want to provide a small Click Once application to a small number of selected users, when the application is published on an otherwise public web server (I don't want everyone to have access to my application). My first solution was to setup a virtual directory (the publish location) with "Anonymous Access" turned off - setting up a special username and password for it which I give to my selected users. The users then 'log on' to the initial install page, and install the application. However, subsequent running of the application should check for any updates - but because the update location doesn't allow anonymous access, the application fails to log on and assumes that its offline, so continues to use the initial version, never downloading any updates. What am I missing? How can you securely publish a Click Once application to a public website? Tag: DataGridView, can it display related from a relationship in dataset in heirarchical View Tag: 111079

    - Establishing VPN Connection Using Extranet Using VB Net 2005, WIN XP. Want to start Nortel Networks' Extranet to establish VPN connection. When that is confirmed, start Netscape using a URL to automatically accessed a web site. Need a method to test when the VPN connection has been established. I tried: I started Extranet using a Process.Start, typed in the information in the Extranet form and submited it. Now I loop while waiting for the connection to be established. Symptom: While waiting I get ContextSwitchDeadLock error. I've tried: I have tried a Sleep function for 60 seconds. Also, I tried to test for memory changes and thread count changes on Extranet.

    - inserting Items in Listview too slow Hi, I need to insert thousands (up to 50000) of items taken from a Database into a ListView control. But this happens to be too slow. Constructing all the items and putting them into an array is pretty fast (split second). But when adding the Items with ListView.Items.AddRange(itemArray) it takes 10 seconds for 37000 items on my machine (Athlon XP 1700+ 768MB Ram). Is there a way to speed the task up, or does anyone know an alternative widget which has basically the same functionality (multi column view with sorting capabilities for each column).

    - GZipStream Decompress always reads 4K minimum...! I have a network stream of data I am reading, of which, a section is compressed and can be decompressed using GZipStream's decompression. This part works great, however, even if the part being decompressed is 1K, GZipStream /always/ reads 4K minimum off my primary stream. Using .NET Reflector I can see they have a 4K buffer internally and always read in chunks of 4K. Basically, I have to force GZipStream to only read what is compressed, and no more. This should be possible because I am reading fixed sized structures out of GZipStream and upon the last structure I should begin reading uncompressed data again. Do I have any options here?

    - COM+ SOAP VB components fail We have numerous COM components that we typically expose through component services "Activation > uses SOAP" mechanism. This has been working great on several servers in the past (w2k3). However, the last four servers we have deployed for our clients - we are having problems... An application we deploy in component services contains about a dozen dlls. It seems that only ones NOT written in VB manage to get their proxy stub created and are subsequently exposed through web-services (via entries in the disco and config files). I have painstakingly checked everything I can think of, and on the servers where it works and the servers where it doesn't - there is no difference in the binaries or the component services settings. As I mentioned, strangely - COM+ dlls written in Delphi work on all servers.... Any ideas? Can I give you more information?

    - Hello World Web Service Hello, I recently developed the hello world web service in Visual Studio 2005. If I right-click on the Service.asmx file that is created, everything works fine in Visual Studio. After verifying this, I did a Publish Web Site for this web service. After that, I installed IIS and wanted to view hello world from another machine to my development machine. However, after publishing the web site, if I go to look at it from another box on the network, I get the following error: The XML page cannot be displayed Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later. A name was started with an invalid character. Error processing resource 'http://192.168.40.20/XMLService/Serivce.asmx'. Line 1, Position 2. After looking around on the net for a while, I've tried the following: \Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i \Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -r \Windows\Microsoft.NET\Framework\v2.0.50727\regsvr32 aspnet_isapi.dll I tried the above for both version 1.1 and 2.0 even though I using 2.0. After that didn't seem to work, I tried re-installing/re-pairing version 1.1 and version 2.0 of the .NET framework. After that didn't work, I tried enabling Access data sources across domains in IE on the client. However, this didn't seem to work either. All I want to do is see the page that comes up in Visual Studio 2005 when I right-click on Service.asmx and select View in Browser from a remote client. Does anybody have any other ideas?

    - 813349: Support for Exchange APIs with the .NET Framework Hi, According to Article 813349, "If the .NET application assemblies do not reside directly on the Exchange Server, Microsoft recommends using WebDAV." But WebDAV can't access Recipient table. So WebDAV can't retrieve Undeliverable email contents (Non Delivery Report). For technical details, please go to Enterprise --> Exchange Server --> Exchange2000.development. Search "WebDAV" for "Re: Detect Undeliverable Email using WebDAV". I was told MAPI is the only way to access Recipient table. But MAPI is NOT supported by .NET Framework per 813349. That's why we implemented WebDAV. My question is if there is a way to at least workaround the problem to retrieve Recipient table to get fields like Undeliverable email addresses, reason codes, diagnose codes, etc. I don't intend to discuss the technical details here. I just like to know what support .NET Framework provides to access Undeliverable emails (Non Delivery Report). Thanks.

    - How to correctly handle exceptions in other threads Hi, I'm building a device application that works on two threads (using VS 2005 and CF 2.0). I'm using threads because one of my operations is quite long (up to 30 minutes or more), and I want to display the user a progress bar and messages in a listbox.

    - Customizing MSBuild I'm working on a big solution containing 12 projects. It takes hours (not realy, but you get the picture) to build and i'm looking for ways to cut corners and increase my "coding-not compiling time". To decrease build time, I created a SlimBuild configuration which only buildt the most necessary projects. This worked great in terms of build time, but as of now, its worthless because the loader project does not copy the dll which are not rebuild every time to the output folder of the loader project. The only dll's which are updated are the ones which are set to be build when i do my ctrl+shift+b. Sadly, it seems that the compiler does not check for newer versions of dll's other than the ones that are set to be build every time. I was wondering i there is a way to customize msbuild to manually copy all dlls in the solution to the output directory of the loader project as a post-build event?

    - Clickonce Prerequisites Order Hi Peoples, I am currently setting up the deployment for our product. The problem I have is that when running the clickonce install on a windows 2000 with no server pack machine I have a problem in that I need to install service pack 3 to install the 2.0 net framework. I want to automate this process in that when the install is clicked and the installer finds that it is installing on a 2000 box it will install service pack 3 and than install the .net framework. I have created a bootstrapper package to install the service pack and have tested this and it works fine. The problem i have is that when i have the 2.0 framework and the 2000 sp 3 prerequisites both selected it will not install because the 2.0 framework is loaded first and sees that the box is running 2000 without the proper service packs and kicks the user out of the install. Is there some way that I can order the prerequisites so that it checks the computer to see if it needs the 2000 service pack, than once thats sorted it does the install of the .net framework? -- Regards, Steve.

    - How can I access internal classes from another assembly? While working with Wintellect's Power Collections, I noticed that they have a unit test assembly that accesses internal classes in their power collection assembly. I thought the definition of "internal" was that you could not access an internal class from another assembly (without using reflection as a back door). I cannot find anything special that they have done, but cannot duplicate it. I must be missing something terribly simple about how assemblies work.

    - using unmanaged dlls from managed dll wrappers. Hi, I hope someone can direct me to the correct newsgroup if this one is not correct. I have a unmanaged C++ dll that I need to use from a C# client. Rather than use dllImport directly, I created a managed C++ dll (in the same solution). In this managed C++ dll, I added a reference (under references) to the unmanaged dll (it's listed under the project tab). I also had to #include the header file for the unmanaged dll in my managed code. Then I created a C# client (.exe.) in my solution to test this idea. In the C# client I simply added a reference to the managed C++ dll. All worked great and I was happy. Now two weeks later, I would like to use this stuff from a real project. From a C# class library (which is used by my C# exe), I call into my C++ managed dll. I of course had to add a reference to the C++ managed dll. Everything compiled. However, when I run, I get the following runtime error: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in CSharpLibrary.dll. Additional Information: File or assembly name ManagedConverterWrapper, or one of its dependencies, was not found ManagedConverterWrapper is the managed C++ wrapper I wrote. I tried adding a reference in my C# class library to the unmanaged C++ dll using the 'Add Reference' tab. It did not work (got error saying could not add non DotNet dll) . Curiously, I was able to add a reference to the unmanaged dll to my managed C++ dll. Was that because it was within same solution or does C++ behave differently with respect to adding references. I also tried copying the unmanaged dll everywhere I could think of (bin/debug of C# class library and C# exe). No luck! My questions are: 1. When one uses a managed C++ dll that in turn makes use of unmanaged dlls, what else must one do to get things working? I.e. Compiler settings, additional references, file copying, etc. 2. Why did everything work fine when all the project where within one solution? Thanks in advance for any pointers, advice or references. Dave.

    - DataRow Iteration Guys if anyone has an answer to this - i'd appreciate some assistance. the problem is not building the dataset within String Builder - so i can render it as HTML in the email msg body. the problem is - the dataset can change and return more or less columns than i have here and my DataRows, Im specifing certain Indexes. so, one time the dataset will have say, 5 rows in it and the next time it may have say 12. i'm about at the edge of my expertise right now, so any code examples from an expert would be appreciated - other wise the only thing i can think of is to build separate Stringbuilder Components and pass a number to them that corresponds with the number of columns retrieved. i've only included enough of the snippets of code in the procedure - to give clarity. i can send all if need be, but the real problem is in the aRow.Item("index") thanks again for any help. rik Public ds As DataSet Dim oMailMsg As MailMessage = New MailMessage Dim sb As New StringBuilder oMailMsg.BodyFormat = MailFormat.Html sb.Append("<p><img SRC=C:\SelectLogo.gif></p><br>") For Each aRow In ds.Tables(0).Rows sb.Append("<table border=1 cellspacing=3><tr><td>" + aRow.Item(0) + "</td>" + "<td>" + aRow.Item(1) + "</td></tr></table>") Next oMailMsg.Body = sb.ToString SmtpMail.Send(oMailMsg) ********************************************************************** Sent via Fuzzy Software @ http://www.fuzzysoftware.com/ Comprehensive, categorised, searchable collection of links to ASP & ASP.NET resources...

    - Running DTS Package from VB.Net but need to pass parameters I can execute the DTS Package no problem. The thing I can't get working is that there is a stored procedure within the DTS package that need 2 parameters passed to it. I thought that if I used the code to add a global variables to the DTS package those would be passed to the stored procedure but that did not work (Put this code in *** below). Any help would be appreciated.

All my efforts to create an exe and dlls that will work on a machine without the 2.0 framework have failed.

    - Patch assembly in GAC Hi, Sorry if I don't post my question in the propper place. If so, please, direct me to the right forum. Thanks :) I have troubles building a patch (a PCP file) that propper update an assembly in GAC. I have setup1 that installs assembly ver 1.0.0.0 in GAC and setup2 that installs the same assembly ver 1.0.1.0 in GAC. When I build a MSP file according to the documentation and apply it, the previous assembly (ver 1.0.0.0) remains in the GAC. The newer one also appears in GAC. Have someone resolved the same problem?

    - FileStream exception: unknown error Hi, Whenever a customer of ours runs our software on any of his laptops, we get an IOException with an Unknown Error (-1) message at every call to the System.IO.FileStream constructor. This is really annoying, as none of our other customers have this problem, and we have no information whatsoever about the error. I looked into the SSCLI code and apparently on the CreateFile an INVALID_HANDLE is returned, and a call to GetLastError returns -1. It has nothing to do with permissions of security, I think, since new FileIOPermission(secAccess, new String[] { filePath }, false, false).Demand(); (filestream.cs, line 263) doesn't throw an exception. I can understand nobody can give me a "This is it"-answer, but could someone please tell me how to debug a situation like this? This is driving me insane...
