• .NET Development Problem in GZipStream Class

  Hi All, I want to compress some data and send it to a web service as string and decompress it there and use it. I use GZipStream class for this and i'm getting an error "The magic number in GZip header is not correct. Make sure you are passing in a GZip stream" when i try to read from the stream. However i dont get this error when i send the stream as byte array.The problem comes only when i convert the compressed stream to string and try to read it (decompress it). Here is the code public static string Compress( string data) { byte [] buffer = Encoding .ASCII.GetBytes(data); MemoryStream ms = new MemoryStream (); GZipStream compressedZipStream = new GZipStream (ms, CompressionMo ...Show All

• Windows Forms Can't disable a button

  I am programming in c#. I have a button on my form that when clicked, it plays a wav file using the PlaySound method from winmm.dll. The wav is about 3 seconds long. The problem is that if I keep clicking the button during the 3 seconds the sound is playing, it queues all of the clicks, and plays the wav over and over. My Button is named btn. So I tried: this.btn.Enabled = false; PlaySound(...); this.btn.Enabled = true; Doing this successfully greyed out the button while the sound is playing, but it still accepts clicks, so it didn't fix my original problem. Is there some way to clear the event queue Or is there something else I'm doing wrong. I just want the button to not work while the sound is playing. I have also tried ...Show All

• SQL Server SSIS- Package Performance Issue

  Hi, I have multiple data flow tasks defined in my package. The task of the package is to extract data from Oracle/InfoLease tables and put them on to a SQL Server 2005 database. Listed below are few queries that I had: 1. In SSIS package, I need to add "Data Conversion" component to convert from Unicode string datatype to String datatype. This was not required in SQL Server 2000 DTS package. 2. By default, Individual transformation is created for each column. Is there a way, to create one transformation for all columns. 3. This SSIS package is being executed as part of a job. The execution time takes around 33 mins. The same functionality of the SSIS package was replicated in form of SQL Server 2000- DTS package an ...Show All

• SQL Server Adding subscibers periodically.

  Hi, In my application, i am sending mails to the respective approvers who have to approve the pending requests allocated to them. Currently,i am adding the subscriber using the sql statement : select distinct users from requestapprover. For every user i am adding the subscriber device info and subscription data. So, this way it will send mails to only those approvers (subscribers) whose ids are stored. How do I add new subscribers because this statement will run only once. Is there a way to add subscribers periodically or a way to run the AddSubscriber.cs periodically, so that the new subscriber can be added. Currently, only those subscriber which are added at the first are added. Is this approach good , if not , pleas ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DrawIndexedPrimitives problem

  Hi, I've got some polygons being drawn with the simple shader using DrawUserIndexedPrimitives(... This works fine on my main laptop with a GForce 7800 card, however I run into problems when I try and run on the same exe on my Samsung Q1 (Intel 915G card, dx9 compat with latest drivers and dx 9.0c). The problem is that it only draws polygons that are intersecting either the front or back clipping planes. DrawUserPrimitives however work fine. So I'm at a loss as to what I'm doing wrong. I've tried setting wire frame / alpha blend / scissor rectangles but still the same. Any ideas Cheers, Steve. This could be a bug in our product. We don't have a Q1 to test against, but I am ...Show All

• SQL Server DTS & .NET

  I have a simple DTS package that is being executed within a .Net application using the MS DTSPackage Object Library. Since I have the SQL Server 2000 desktop tools installed, the package executes with no problems, however, when another user tries to execute it, the following exception is thrown: Retrieving the COM class factory for component with CLSID {10020200-EB1C-11CF-AE6E-00AA004A34D5} failed due to the following error: 80040154 I've tried including all the DTS references, rather than just the Package object reference, and that didn't help. Thanks in advance for your help. THis is really frustrating. 0x80040154 is 'class not registered', i.e. DTS is not installed on this machine. Solut ...Show All

• Visual C# Printing PDF from specific printer tray problem

  Dear all, For a C# project I would like to be able to print PDF documents from specific printer trays. Up to now I did succeed in doing half the work. 1. I can print PDF documents by doing a DllImport of winspool.drv and send the raw bytes to the network printer. By doing so, the PS/PDF capable printer understands the PDF bytes and prints the PDF flawlessly albeit using the default printer tray. I thought of making copies of the printername with different default trays and use the different names in my application, to no avail... 2. I found a way of printing with different printer trays (using WMI or even better C# PrintDocument). This works perfectly apart from that it is only capable of printing Strings (plain text that is). When I open ...Show All

• SQL Server Set QUOTED_IDENTIFIER and ANSI_NULLS on all objects...

  Is there any way via T-SQL to run through a database and ensure that QUOTED_IDENTIFIER and ANSI_NULLS is set for all stored procs and functions etc on a database without having to recreate every proc / fn The reason this is an issue is I'm trying to take advantage of indexed views to get a performance increase in an application - but not all of the procs/fn's have historically been created with ANSI_NULLS and QUOTED_IDENTIFIER set - so any proc that's not set correctly will fail once the indexed view has been created. I could I suppose, script out all the procs / functions and do a bit of search and replace to ensure that these are set correctly by recreating all procs and functions - but I'm trying to avoid doing that as I've over 500 da ...Show All

• SQL Server Programmaticaly associating a schedule with a deployed report?

  I have a report deployment system (in C#) set up such that it takes all the RDL files in a folder and deploys them to the target server. Since many of these reports are computationally fairly expensive, I wanted them to display from a report snapshot, on a daily schedule. Although I know how to do this manually via Report Manager, I wasn't sure which SOAP methods to call on the ReportingServices webservice to make this happen. Anyone have any experience with this or tips Thanks, Arjun It can be set using SetExecutionOptions method ( http://msdn2.microsoft.com/en-gb/library/microsoft.wssux.reportingserviceswebservice.rsmanagementservice2005.reportingservice2005.setexecutionoptions.aspx ) ...Show All

• SQL Server What does AverageOfChildren aggregate function in SSAS 2005 actually do?

  Folks, Have any of you been playing around with SSAS 2005 to have worked out what the AverageOfChildren aggregate function actually does I was expecting it to do the equivalent of a simple AVG() with a GROUP BY in SQL, but it seems to be doing something additional to that. No-one in the team I work in has been able to work out what exactly it is doing. Any info would be appreciated! Cheers, Kenneth If I'm interpreting what you're saying correctly then, AverageOfChildren works like an average if you are aggregating by a time dimension, but doesn't for any other type of dimension. I suppose the next question would be... why! Why didn't Microsoft provide an aggregate function ...Show All
