  • GDI+, using DrawImage to draw a transperancy mask of the source image

    - by sold
    Is it possible to draw a transperancy mask of an image (that is, paint all visible pixels with a constant color) using Graphics::DrawImage? I am not looking for manually scanning the image pixel-by-pixel and creating a seperate mask image, I wonder if it's possible to draw one directly from the original image. My guessing is that it should be done with certain manipulations to ImageAttributes, if possible at all. The color of the mask is arbitrary and should be accurate, and it would be a plus if there can be a threshold value for the transparency.

  • Need help recovering a corrupt SQL database

    - by user570079
    I have a very special case that I have been working on for several days. I have a very large SQL Server 2008 database (about 2 TB) that contains 500 filegroups to support very large partitioned tables. Recently we had a catastophic failure on one of the drive and lost several filegroups and the database became in-accessible. We have been doing filegroup backups on a daily basis, but due to other issues, we lost our most recent backup of the log and the primary filegroup. We have all the data backed up but the primary filegroup backup is old. There have been no schema changes since the primary filegroup backup, but the lsn's are now all out of sync and we cannot recover the data. I have tried everything I could think of (and have tried just about every trick and hack I could google) but I still end up at the same point where I get messages saying that the files for filegroup x do not match the primary filegroup. I am now at the point of trying to edit the system tables (we have a separate temporary environment to do this so we are not worried about corrupting any production databases). I have tried updated sys.sysdbreg, sys.sysbrickfiles, and sys.sysprufiles to try to trick SQL into thinking all the files are online, but a "Select * From OPENROWSET(TABLE DBPROP, 5)" shows a different database state from what I see in sys.sysdbreg. I am now thinking I need to somehow edit the headers of the actual data files to try to line up the lsn's with the primary. I appreciate any help anyone can give me here, but please do not respond with things like "you are not supposed to do edit mdf, ndf files...." or "see msdn article....", etc. This is an advanced emergency case and I need a real hack so we can just get to the data in this corrupt database and export to a fresh new database. I know there is a way to do this, but not knowing what the DBPROP system functions does (i.e. does it look at system tables or does it actually open the file) is keeping me from trying to figure out how to fool SQL into allowing me to read these files. Thanks for any help.

  • Storing records in a dropdownlist from DB without using LINQ Data source

    - by user1318369
    I have a website for dance academy where Users can register and add/drop dance classes. In the web page to drop a particular dance, for a particular user, the dropdown displays her registered dances. Now I want to delete one of the dances from the list. So i'll remove the row from the table and also from the dropdownlist. The problem is that everytime the item with the lowest ID (index) is getting deleted, no matter which one the user selects. I think I am storing the DataTextField and DataValueField for the dropdown incorrectly. Can someone please help me out? The code is: private void PopulateDanceDropDown() { var registereddanceList = from dd in context.DANCER_AND_DANCE where dd.UserId == dancerId select new { Text = dd.DanceName, Value = dd.DanceId }; dances.DataSource = registereddanceList; dances.DataTextField = "Text"; dances.DataValueField = "Value"; dances.DataBind(); } protected void dropthedance(object o, EventArgs e) { String strDataValueField = dances.SelectedItem.Value; int danceIDFromDropDown = Convert.ToInt32(strDataValueField); var dancer_dance = from dd in context.DANCER_AND_DANCE where dd.DanceId == danceIDFromDropDown select dd; foreach (var dndd in dancer_dance) { context.DANCER_AND_DANCE.DeleteOnSubmit(dndd); } try { context.SubmitChanges(); } catch (Exception ex) { Console.WriteLine(ex); } PopulateDanceDropDown(); }

  • xcopy not accepting a relative path as source parameter on certain computers

    - by slicedtoad
    xcopy /e /q ".\dlls\*.*" "%programfiles(x86)%\foo" >> TEMP xcopy /e /q dlls "%programfiles(x86)%\foo" >> TEMP xcopy /e /q ".\dlls" "%programfiles(x86)%\foo" >> TEMP All of the above work on two of my machines (windows 7 64bit). But on two peers' laptops (windows 7 64 bit and windows 8 64bit) they return file dlls not found or (in the case of the first one) file *.* not found Can someone shed some light here? The only difference I can see between the machines is possibly permissions. But I don't see how that would affect xcopy's ability to recognize a local path.

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

  • Delete data from a MSSQL standby database?

    - by SQL-Newbie
    Is it possible to delete data from a read only standby database that imports shipped log files? At least in my theory this shouldn't be possible because the deletion would change the LSN and the log shipping should break. What I need is a smaller sized database than the database that ships the logs. So basically I need a way to have the (readonly) standby server storing only the most recent data. Any ideas or recommendations on this?

  • LDAP user data caching on local database

    - by Eduardo
    I am integrating LDAP authentication in my web enterprise application. I would like to show listing of people name and email. Instead of querying the LDAP server for the name and email each time a listing containing several users I thought about caching the data locally in the database. Do you guys know about caching LDAP data best practices? Should I cache LDAP user data? When should I insert and refresh the data?

  • WPF control not being updated when source is changed

    - by Dave Colwell
    Hi, I have a ListBox which is bound to a list of objects. When the system initializes, the binding is done just fine, When i update the value in one of the fields on the ListBox, the item in the background updates as well, but when i update the value in the background it is not reflected in the ListBox. Does anyone know why this is?

  • Printing data in Excel ver 14.0 in a maxed cell

    - by Zppy
    I have set the cell to the maximum size (column width of 255 and row height of 409.5). In order to view all of the data in the cell, I have to use up/down arrows. I don't need to necessarily view all of the data in the cell at one time, however I do need it to print, and it's only printing what's viewable (not what you can scroll through).....any suggestions on how to get the entire cell to print? Thanks!

  • [Java6] Same source code, Eclipse build success but Maven (javac) fails

    - by EnToutCas
    Keep getting this error when compiling using Maven: type parameters of <X>X cannot be determined; no unique maximal instance exists for type variable X with upper bounds int,java.lang.Object Generics type interference cannot be applied to primitive types. But I thought since Java5, boxing/unboxing mechanism works seamlessly between primitive types and wrapper classes. In any case, the strange thing is Eclipse doesn't report any errors and happily compiles. I'm using JDK1.6.0_12. What could possibly be the problem here?
