• Windows Forms Accessing the value of a a DataRowView from a ListBox (How)?

  I'm trying to use a form with a ListBox to select from and populate another ListBox depending upon the selection in the first. The first is populated by a query to a project resident .mdb file. I'm running into a problem when it comes to figuring out the value of the item selected in the ListBox. I can see that the object selected upon the firing of the SelectedIndexChanged event is of type System.Data.DataRowView, but try as I may, I cannot figure out how to get access to the actual values ( strings " Core" and "Special" in this case). Am I missing a necessary cast somewhere, or is it just a property or method that I missed Am I trying to use something entirely wrong for the situation Any help would be greatly apprec ...Show All

• .NET Development PNG transparency being clipped

  I have an application that allows a user to position a graphic on a surface. Once the graphic is positioned, it is saved as a PNG that is set to a certain size. The image is always saved as the same size, so that the image will have different amounts of transparency, depending on how large the sub-image is. Later on the image will be reloaded and positioned at a known point, and the transparency will provide padding to make sure that the sub-image is in the right place. Make sense My problem is that when I load an image from a database, like this: primaryImage = Drawing.Image.FromStream( New IO.MemoryStream( DirectCast (primaryImageData( "ImageData" ), Byte ()))) It somehow comes out with all of the transparency cli ...Show All

• SQL Server SQL 2005 Express and Visual Studio 2003 - Connecting

  I have Visual Studio 2003 and had used it successfully with MSDE. I recently upgraded to SQL 2005 Express and cannot seem to connect to the SQL server. it appears in the list of servers on localhost, but when I try to create a new database it tells me that it "cannot create databases on this server." It will not even open up any existing databases. I have .NET 2.0 installed. I uninstalled SQL and reinstalled it, but nothing seems to help. I feel I must be missing something, but do not know what. I no longer have the MSDE installation files, so I hope I can get Studio to talk to SQL Express. Any help is appreciated. Further checking in the services list showed that SQLEXPRESS was fro ...Show All

• Visual Studio Team System Project/TFS Integration issue - please help

  Ok, this is my last effort before opening a ticket with Microsoft and spending the rest of my life on the phone with them. I have Project Server setup, and I have it receiving its data from TFS. The data is replicating between the 2, etc. Here is the problem. When I click "Refresh" on the Team plugin for project a couple times, the data will change. Here is an example: I have a work item with Actual (Completed) Work set to 8 hours. This shows in TFS. Refreshing it in project shows the 8 hours fine. However, if I refresh again it changes it bakc to 0. Clicking refresh 2 more times sets it back to 8, hitting it again makes it go back. This happens with most of the work items, and I cant for the life of me figure out what it is. ...Show All

• SQL Server How service broker queues can be mirrored?

  Hi, I want to know that how is it possible to achieve mirroring for the service broker queues in the database Since mirroring mirrors the entire database and queues, services, contracts, message types etc are all entirely contained within the database, the queues are mirrored too when a database is mirrored. Note that in order to reach a service (and a queue) hosted in a mirrored database, a mirrored route must be used, as described here: http://msdn2.microsoft.com/en-us/library/ms166052.aspx HTH, ~ Remus ...Show All

• Software Development for Windows Vista getting started: ideas for workflow in my content mgt app

  Can someone please offer me a architectural guidance/overview of how to use Windows workflow in the following scenario. I'm starting from a clueless point, so, any elementary guidance/samples to start from would be great. My (new) WCF web service will host the workflow runtime. Web requests will be requests that move a particular workflow, fetch available next states and events, get status on current state. Below are some super simplified examples: //this adds the document and binds to a preexisting workflow, and transitions AddDocument( newDocument, workflowID, "Ready") //this gets stages and events available for the document GetDocumentNextStages( documentID) GetDocumentNextEvents( document ...Show All

• SQL Server Row count validation between source flat file to target database table

  Hi all, I am new in SSIS. Anyone know how to valify number of record that I load from csv file to SQL database table For example, the source file call product.csv and target table in database named DSS table name PRODUCT. I load data from flat file to table then I need verification if count between source and target not match send e-mail to me. Thanks. Grace After your data-flow you should put a Send Mail task.

• .NET Development Acessing an Excel Sheet from a .Net web application

  I have a requirement where i need to import Excel data into a web application. The catch is I don't know in what format the data is i.e. either the columns can represent fields or the row represents fields. In case the column represents fields I can access the data. However in case the rows represents fields I am unable to do so. Any idea how I can handle a situaltion like this The difference lies in the orientation of the fields of the table in the excel sheets. The excel will be provided to the web application by the end user and there is no definite format of the same. As such all possibilities have to be considered. ...Show All
