• Visual Basic Unable to cast COM object of type 'X.YClass' to interface type 'X._Y'.

  Dear all, I'm getting this nasty error and I cannot find any answers (google didn't help either). Here's the thing: I'm calling a VB6 DLL from a VB.NET (VB2005) application. This is the error I get when I call the DLL: Unable to cast COM object of type 'X.YClass' to interface type 'X._Y'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{780BDA61-8169-4A5D-AD31-59A902BC3B84}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Strange thing is, sometimes my code works properly, and the next hour I get this error. I rebuild the DLL, unregistered and re-registered the DLL, swept through the internet and the ...Show All

• Visual Studio Team System TFS SP1 and problem with get latest version

  Hello, I have installed TFS SP1 and have got the problem with VersionItems table. When I try to do "Get Latest Version" operation the error occures in rpc_Get stored procedure. It says that there is a collation conflict (SQL_Latin1 and "normal" Latin1). The stored procedure is encrypted so I cannot know what it tries to do. All other operations (check in, change workitems, etc) seem to work notmally. Can anyone help me and explain how to fix the problem Thank you. This was a bug which we fixed in SP1 RTM. It would occur if your TFS version control database collation was different than the collation of your tempdb. Alexey - did repairing SP1 work out ...Show All

• .NET Development Avoid serializing base class members

  Hi, I have extended System.Windows.Form.Label control and I also implement one additional interface containing some properties. public class MyLabel: System.Windows.Form.Label, IMyInterface { //... } What will be the simplest way to serialize an instance of MyLabel class to include only IMyInterface members. I do not need to serialize any of base class (Label) members. Thank you. Thank you Daniel, Of course I can apply your solution if the number of properties for the base class is relatively small. But for classes deriving from a Label control there is a lot of work... Trying to save some time by using IXmlSerializable ... I was just wondering if there is something in .NET Seri ...Show All

• SQL Server can service Broker talk to informix

  Hi, I am very new to Service Broker. Can I have a Service Broker which will Exchange Message from Informix and service broker sitting on SQL Server Box. If this is possible, How can we achieve it. Any Pointers will be very helpfull. Thanks Hello Remus, This seems fine for Informix installed on Windows, but in my case, I can have Informix on Unix Machine also. Therefore I want to have a generic design for both the cases, So that I don't have to do much of change when Informix is on Unix or Windows. That is the reason why I did not try to use Linked Server. Can a Service Broker Communicate with a service running on informix box. Thanks Dharmbir ...Show All

• Visual C# C# Remoting on PDA alternative

  I've just done an exam job on remoting on a PDA but I realized that this is not possible.. So therefor I need to know how I can make the same effect in another way.. I mean I can't make a remote connection on a PDA so what can I do to control my object on the server i've been in a similar situation, my best advice would be to use a webservice.. there are a few ways to accomplish this.. if IdeaBank, Subject, and Idea are all coming from a database somewhere, you can have your webservice call return a DataSet with with a DataTable for each.. This is the most painless way to do it, but isn't necessarily the best. A better way would be to ensure that IdeaBank, Subject, and Idea all support Xml Serial ...Show All

• SQL Server How to retrieve Top 3 records in the group level

  Hi all, I have a report which is grouped by a field called R_ID, which gives me a list of records for each R_ID. So here is the thing, I want to get only top 3 records for each R_ID. Is there any way to do this thing in the report level. I tried it from the query level, but the result is not like what I wanted. Please let me know if some body has any idea. Thx. Doing this in a report wouldn’t be the best way as you would get all the data from the server and then only would display a part of it. better filter the data on the server and send only back the appropiate results, then you would have no problem on the client / reporting service. Anway, if you want to do this, you might have a look at ...Show All

• Visual Basic Changing System Environment variables from VB6

  Hi All, Does anyone know of a way to change a system environment variable from within a VB6 program I have tried Environ() and SetEnviromentVariable - they only set/change environment variable that are visible to the application NOT the system.

Any help offered will be greatfully received! Thanks in anticipation. Ed These forums are for questions regarding .NET programming. VB6 is not supported here.

• Visual Basic how to get modified default filename when saving, based on the first line

  hello, i would like to create a system for a rather large amount of univ books, that i would name based on the section name and number them (eg: 0001_physical-clock.doc). this section name is usually the first line after the header. how can i create a form ( at the beginning of the word document ), so the contents of it would be added to the filename when saving ( saving me from typing it, much less finding it ) thank you hello again, thank you for your replies, i now know what i'm looking for. @spotty: yes, i am looking for a solution that would be entirely contained within word and hopefully, again entirely, automated. since i'm totally new to this kind of scripting, could you please point me to the f ...Show All

• Visual Studio 2008 (Pre-release) Extension Methods / Property conflict when they have the same name

  I have a question regarding how properties of the same name as an extension method are resolved. In the following example, i'd like q3 to compile. I understand the compiler might have issues with the name conflict, but there is a valid extension method, and the compiler is getting hung up because there is also a property. It can resolve it if i explicitly supply the generic type as in q4 - Why can't it be smart enough to do it for q3 List < int > nums = new List < int > { 0,1,2,3,4,5,6,7,8,9 }; int q1 = nums.Count; // works - uses the property on List<T> int q2 = nums.Count(); // fails: 'System.Collections.Generic.List<int>.Count' is a 'property' but is used like a 'method' - doesn' ...Show All

• SQL Server Creating A tab delimited export

  Hello all, I am trying customize the CSV rendering extension with different device information settings. I would loke to change the CSV extension to a Tab delimited output.

• Visual Studio Team System Email notifications stop working after a while

  I have some email notifications which are to be sent out on events (buildqualitychanged, buildcompleted, etc.) These work fine for a while, but every week or so they stop working and I have to reboot and then they start working again. I have to do this at least every week (more often recently). Are there any known issues about this Hmmm....I suppose that it could be something to do with the SMTP server since all of the other non-mail subscriptions continue to work. However, the SMTP server is on a different server and everything starts to work again after rebooting. (i.e. all emails which were not previously sent out are now sent out after a reboot). ...Show All
