• .NET Development Plugin Security

  How can i assign a CAS permissionset to a dynamically compiled and loaded assembly so as to prevent it from executing malicious code. It seems that this is needed for any kind of Plug-in architecture but I cant find a solution to the problem. I need the compiled code to run in a totally different security context than the application code, however i need it to be able to make callbacks into the application code to perform things like IO, or network access in a controlled way. I'm scratching my head here cuz there just are no samples. In order to successfully sandbox code, you need to keep it in a se ...Show All

• Visual Basic Setting the Primary key as a foreign key in an intersection table

  I need to be able to add information to table1 then click a button to bring up a new screen with information from an intersection table, table2, and another table, table3, while putting the PK from table1 into table2 for several records. Table3 is a static table and will not change so I know how to do that, but I don't know how to do it with a table that will not remain static. I am using VB '05 Express and SQL '05 Express. Simplified version: I need to be able to put a primary key as a foreign key into an intersection table. TABLE1 ............... TABLE2 ..................

• SQL Server MySQL to SQL Server migration

  Hi, I would liked to know the SQL Server equivalent for the below MySQL query : SELECT a.col1, a.col2, max(a.col1) FROM test a, test1 b WHERE a.col2 = b.col2 GROUP BY a.col1 Thanks, Smitha You can do it the same way except you can't just show a.col2. You use groupby, so it must belong to some logical output. You can do it like: SELECT a.col1, max(a.col2), --or other functions... max(a.col1) FROM test a, test1 b WHERE a.col2 = b.col2 GROUP BY a.col1 OR SELECT a.col1, a.col2, max(a.col1) FROM test a, test1 b WHERE a.col2 = b.col2 GROUP BY a.col1, a.col2 Hope it helps ...Show All

• Windows Forms System.Deployment.Application missing! (VS2005 Beta 2)

  Hi! My first post on here, so be gentle! I'm running Visual Studio 2005 Beta 2 and experimenting with ClickOnce deployment to work. So far so good, but I'm trying to get the publish version in code, so I can display it in an "About" box. The following thread says you can find it in code using the property System.Deployment.Application.ApplicationDeployment.CurrentDeployment.CurrentVersion http://forums.microsoft.com/msdn/ShowPost.aspx PostID=9145 However, the namespace System.Deployment.Application doesn't seem to exist on my VS2005! Intellisense only recognizes one namespace within System.Deployment and that's the unhopeful-sounding Syste ...Show All

• Windows Forms Deployment identity does not match the description

  Hi, I have a ClickOnce project that had been working fine for several deployed versions. At some point something happened and I began getting errors when I tried to publish -- "Cannot publish because a project failed to build" (even though there were no build errors). and "SignTool reported an error 'Keyset does not exist.'" I couldn't resolve these issues, so I created a new project and imported the forms, classes, reports, etc. It works okay and will publish fine, but if I publish it to the original location, when a user runs the program and it tries to upgrade to the new version, they get "The deployment ide ...Show All

• Visual C++ Date time stamp can't be this difficult

  Hi, I'm writing what should be a simple program to auto-edit a text file.  If an error occurs, the program makes an entry in an errlog file which should include an date/time stamp. Unfortunately, I can't figure out how to do it.  I started in namespace std and included <string>.  I found <ctime> but as I struggled to make it work, I received warnings that it was deprecated. After some digging, I found DateTime, which required that I change to namespace System.  So, now I have a function that finds the date and time but I can't use it because my program uses strings and the DateTime.ToString() functions returns ...Show All

• SQL Server Improving Cursor Performance

  Hello Can we use rowsets in sql server triggers and stored procedures for improving cursor performance. Any other solution in this context is welcome Chikuu Why are you using cursors There are very few problems that require use of cursors. And using them within triggers is even more of a performance hit. Try to use set-based operations inside triggers so it can execute quickly and reduce blocking issues which can otherwise happen due to long running trigger code. Maybe if you post a simple example of what you are trying to do with the cursor it will be easier to suggest a set-based alter ...Show All
