• .NET Development How to generate custom code based on a custom method/sub/function attribute

  Our team is looking into performance logging; rather than asking developers to manually insert code for entry and exit timestamps we'd like to provide a custom attribute that they could attach to a method/sub/function of interest; this custom attribute would then cause, at runtime, a consistently formatted message with a timestamp to be logged at entry and another on exit, regardless of normal exit versus the throwing of an exception. I feel this could be done if code could be generated for such an attributed function that basically put "whatever code was there" in a try...catch...finally.  Then in the catch, re-throw whatever was thrown, and in the finally do the exit timestamp. example pseudocode, I wo ...Show All

• .NET Development Attempted to read or write protected memeory. This is often an indication that other memory is corrupt

  I am getting : Attempted to read or write protected memeory. This is often an indication that other memory is corrupt in a number of different applications. Mainly I am getting it in applications where I am using DLL functions. For example I am talking to an OLAP database through its API which sit in a DLL. When I am processing more than database the same code causes the above message to appear on the second database.I open and close the database in the appropriate places which is supposed to load and unload the DLL, But aside from this application I have other applications which work fine on some machines and not on others. An example of this sort of application is a Crystal Reports with subreports which works fine on some machin ...Show All

• .NET Development StDev returns NaN

  Hi Everyone: When using the code to calculate the StDev of a data column, it returns NaN. But all other aggregate functions, like Sum, Count, Min or Max return a number on the same data column. It seems this function has a limit on the maximum number of rows it can hundle. The number of rows in the column is 46712; if I reduce the row number to 46064, it works. DataTable.Compute("StDev(DataColumnName)", "") Does anyone has this problem before Does anyone know under what condition, this function returns a NaN Thanks. What's the version of .Netframework are you using What's the data type of the column It might have something to do with integrate overflow. 46712 * (4 ...Show All

• SQL Server USE MULTIPLE ROLES IN CUBE BROWSING

  Hi, I'm developing a cube browsing aspx application using the OWC11 controls, both Pivot and Chart, associated with Analysis Service on SQL2005. I did quite a bunch of that but now I'm having some troubles to solve the following problem. Using the SSAS IDE, I defined two Roles in a Cube and I defined a filtering function on the dimension in both of them. When I choose each one of them and I check the functionality they works because I can see what I expect to see, only one result from a dimension where the filter is acting in the role definition . But, if I choose both of the roles, and I can do that because it let me select the two checkbox instead of all (having more than two Roles), the filter doesn't work anymore, showing a ...Show All

  Hi, I wanted to know how to create certificate and use it for client server communication using sslstream. i downloaded the example from http://www.leastprivilege.com/SslStreamSample.aspx site but iam unable to run the example because of certificate. so please help me in creating the certificate and using it in the example. thanks vijayalakshmi Got this one working :-) I used makecert.exe to create the key. ensuring it had my machine name set and was marked as exportable.

• .NET Development Strange behavior when making remote call

  I'm calling a remote server (client activated, hosted in WinForms app). A simple call without parameters (or with a simple string param) works fine. When I pass certain parameters, it crashes. Build is the remote class. This call to CreateBuildTree() works: Build prp = new Build (); prp.CreateBuildTree(); This one doesn't: Build prp = new Build (); string BuildDir = prp.GetBuildDir(); TreeNode root = new TreeNode (); root.Text = BuildDir; prp.CreateBuildTree(root, BuildDir); even when CreateBuildTree doesn't contain any code!!! public void CreateBuildTree() { } The error I get on the client side is "Server encountered an internal error.
