• Visual C++ Why is base class destructor unresolved in Release mode (VS2005)

  Abstract base class, Foo, exists in library F Derived class (from Foo), Bar, exists in library B Module M uses Bar (but never Foo directly). Linking M to B satisfies all external references in Debug mode. In Release mode, however, linking of M complains that the reference to Foo’s destructor is unresolved. This seems inconvenient. It is caused by optimization because if you disable the optimization on M, there is no link problem. Can this behavior be justified Does anyone understand what sort of optimization is happening that causes this behavior Is there a way around this other than either disabling optimization or linking M to F (also setting M’s C++ Properties/Optimization/Whole Program Optimizat ...Show All

• .NET Development Editing and Deleting nodes in VB

  Howdy, I'm working with a program using an XML file, and I'm trying to delete and edit nodes and attributes (well, delete nodes and edit attributes). I've looked around a fair bit, including through these forums, and simply can't find any good easy-to-use tutorial or documentation on this sort of thing. Does anyone know how I can edit or delete nodes using VB.NET, or any tutorials Any languages is pretty much fine (I can sort of try to translate it, but I would really prefer something about VB.net, if anyone has something of the sort). I've looked all over, and can't really find anything that I'm looking for. Thanks so much! Anything really is greatly appreciated. Thanks again! -Robert Hi, I tried looking up the documentation on ...Show All

• SQL Server How can we verify the Clustering algorithm models?

  Hi, all here, Since we are not able to use accuracy chart for Clustering algorithms there. So how can we verify the accuracy of clustering algorithm models here in terms of its classification and regression tasks Thank you very much in advance for your guidance and advices for that. With best regards, Yours sincerely, Actaully, you are able to use accuracy chart if you define any columns as predictable for the clustering model. You can verify this by using the Targeted Mailing data set from the Adventure Works DW. You can create a Microsoft Clustering model and set the bike buyer as predict. After you process your model, you will be able to get lift chart, profit chart and classification matrix for your clustering m ...Show All

• SQL Server Connection String Encryption for SQL Server Mobile

  I'm seeking suggestions on how to go about encrypting a database connection string in the compact framework. It's something that I thought would be relatively straight forward as I've accomplished it without much difficulty in the full framework, but I'm stuggling to find a solution. I've been trying to implement a solution using public/private key asymmetric encryption using the RSA provider. I've essentially been trying to encrypt the connection string once on my development machine so that I can include both the encrypted connection string value and public key in either code or an external file. I'd then keep the private key out of harms reach. The problem I've encountered in doing this is that that RSA provider seemingly only allows ...Show All

  Hi, I am performaing a load test on one asp.net application. In the results I see the execution time counter of ASP.NET to be very high(100 sec) .

What could be the reason of having high execution times Thanks.

• SQL Server Using Webservice in ReportViewer Control

  HI I want to use ReportViewer Control to show the data. Can I render report using Sql Server 2005 Reporting web service call. I didn't get any sample which allow me to host report on reporting server but view them using ReportViewer Control using webservice call rather than using URL. I need to hide Reporting server URL location. And If you show report using ReportViewer Control using URL mechanism, anybody can see the report server url. If you use the viewer control ( www.gotreportviewer.com ) hosted from an ASP.Net application, then you can isolate the user from the backend report server. In fact, it does this by default. ...Show All

• Windows Forms Sorting a treeview

  I have extended the TreeNode class to make my own class that has an extra property called 'order'. When my TreeView is initially populated new nodes are assigned a value in their order field. I've also defined my own IComparer class (TreeNodeSorter) that sorts the node based on this order property. When the Tree is populated or a new node is added at a later point then it is inserted in the right place according to the sort. However, I also want to be able to change the 'order' field of an existing node and for it to be then put in the right place. I originally tried this by updating the order field and then calling treeView1.Sort() but it didn't work. Can anyone tell me how I'd go about doing this please Thanks in advance, Tom ...Show All

• Windows Forms How to increase maximun folder/file path value

  Hi All, Windows operating system do not allow user to create a folder/file whose full path is greater than 260 characters. For example if we try to create the following folder hierarchy in windows OS, it will not allow us to create the same because last folder's full path contains more than 260 characters:   C:\This is my folder on level 1\This is my folder on level 2\This is my folder on level 3\This is my folder on level 4\This is my folder on level 5\This is my folder on level 6\This is my folder on level 7\This is my folder on level 8\This is my folder on level 9   In my current project we can't restrict user for the same, so using small names for the folders is not an option for us. &nb ...Show All
