• .NET Development security code groups and subgroups at the enterprise level

  I hope I'm asking this question in the right place. If not, please point me in the right direction. I'm trying to create a security template to distribute within my organization. The organization demands that I set the "All_Code" code group to the "Nothing" permission set, and then we will publish a new exception for each and every .Net application we distribute to our end users. Basically, this will mean that no .Net applications will run unless we provide explicit permissions for it to run. The problem I'm having is that I can't seem to make it work. I have an example app I downloaded from a code example site (all it is is a button that ...Show All

• Visual Studio Express Editions VB Express Reporting capabilities

  For the moment there is not any reporting capabilities in vs express editions (except for vs web developer express editions). Is it true that MS will provide  such reporting Add-ins for other express  editions in near future if true, When   Seems everyone wants reporting . I'm not aware of any reporting tool for use with the express edition(s). If there was, I'm guessing it wouldn't be free. However, you have several options: Upgrade to one of the full versions (Standard or Pro, which you will have access to the SQL Server reporting services, or Crystal Reports in ...Show All

• Software Development for Windows Vista InsertTrackingProfile doesnt seem to exist

  I am trying to get a basic tracking profile created and installed. The problem is that the online docs have a CreateAndInsertTrackingProfile() that wont compile.

• Windows Forms creating a DataMember property that shows list of fields at design time

  I have created a custom control that inherites from TreeView and then exposes properties so it can be bound to a hierarchical table. I expose the DataSource, DataMember, ParentMember, and ValueMember fields and then use these to build the tree based on the table data. This all works, but when the developer assigns the DataMember property, it is just entering the column name as a string and has no checking. How can I make the DataMember show a drop down list of the columns in the DataSource like the ComboBox and other controls do Dave ...Show All

• .NET Development System.Net.Mail: Method Clear() of MailAddressCollection leaves 1 element unremoved

  Visual Studio 2005 Version 8.0.50727.42 The task is to send an email to every recepient that is contained in a DataTable. After MailAddressCollection.Clear()   MailAddressCollection.Count changes to zero, but the next message sent still contains the first MailAddress added to the MailAddressCollection. This can be seen only if there will be no new MailAddress added to the MailAddressCollection - see below if column "EmailCC" is empty. Very strange. Any idea except from creating a new MailMessage for every recepient private System.Net.Mail. MailMessage  _Msg; foreach (System.Data. DataRow row in table.Rows) ...Show All

• Visual Studio Express Editions valid assemble and com component for dll reference

  Hi, I am trying to add a DLL reference into a C# project in 2005 Express. But it says not a valid assemble or com component. Any idea where shall I look into Thanks... If it’s not a COM or .NET dll then you shouldn’t be adding a reference that way, instead you’ll want to look into P/Invoking it. Is it a common Windows DLL If so take a look at Pinvoke.net for a huge collection of signatures that can be used to get it working in your app. If not, you’ll need to write your own, which in itself is pretty easy. Take a look at this Platform Invoke Tutorial for more info to get you started. ...Show All

  Hi: one of our study group members noticed a strange behavior and has the following question. Any thoughts are appreciated.

The severity of Insert into t3 values ( 3 ) is Msg 208 , Level 16 , State 1, Line 2 Invalid object name 't3'.
