• Visual Studio Express Editions Database Project in VB2005EE

  I am building a small database app. I have a question about displaying data from the DB on a form. I have a form with a listbox and several textboxes. In the listbox I have a list of items from the database (Table A) and when I click on an item in the list the textboxes populate with appropriate data from the database (Table A) applicable to said item. To this point all works well. Now I want the listbox list to be sorted alphabetically. I change the Sorted property of the listbox to true and the list now displays alphabetically but selecting an item in the list now displays the wrong info in the textboxes. I must have to change a setting or Cam This is my code at this point with er ...Show All

• .NET Development NET Framework written in C++?

  Hello there, the thing I want know is: In which language is .NET written. I am sure .NET supports so much prog languages, but in which language the .NET Framework was written (I mean the IDEs, the libs like System.dll, the interpreter). Another question: What about C# Is this language written in Assembler or was it created trough C++ like lots of other langs I am looking forward to hearing from you! Best regards Ian Peter is right, the vast majority of the framework is coded in C#. The C++ methods are fairly easy to spot if you look through the classes with a tool like Lutz Roeder's Reflector as they are decorated with [MethodImpl(MethodImplOptions.InternalCall)]. There are no 'pure' assembly methods as far as I kno ...Show All

• Visual Basic null TextBoxes in Database Entry Form

  Hello, 1. The Form has TextBoxes c1,c2,c3 receiving currency and c4 which shows the totals: c4=c1+c2+c3 As it is now, an "Add New" Button_Click event initialize all the TextBoxes to "0.0". While this works, it places a burden on the user when entering data (he has to erase the "0.0" or might make a mistake say typing "1" without erasing "0.0" turning it into "10.0"). 2. How could the c4 always show some result, starting from the initial 0.0 to c4=c1 then c4=c2 c4=c3 or c4=c1+c2 or c4=c1+c3 or c4=c1+c2+c3 Thanks, Hi Spotty, Thanks for your time. The EntryForm is the front-end to a Database and a somewhat more complicated that it was posted originally. (It h ...Show All

• Visual Studio Team System History information doesn't show up after branch?

  I recently performed a branch operation. It seems that after the branch my history information doesn't show up. It shows up for the source of the branch, but not for the newly branched items. I need the history information to show up in both places. How can I accomplish this You may want to look into the CodePlex project codenamed "Vertigo" ( http://codeplex.com/Wiki/View.aspx ProjectName=TFSVTreeBrowse ).

• Visual Studio Team System deploy/schema compare scripts - Option for checking IF EXISTS

  My scripts need to check for existence of tables, columns, etc. before creating or altering. My procs and functions need to check existence and drop if they do already exist then create. Is there any way to control script preferences to accomplish this Hi, just an idea (not sure of the feasability). I am assuming that your customers that you can not "connect" to are NOT manually modifying their copies of the DB schema themselves. Couldn't you deploy copies of the DB Schema for each customer DB (without data ) in your environment Then the build would have access to the customer schema and you could have the different status reflected each of the build scripts. Of course you would have to ...Show All

• Visual J# permission question

  I have a J# class BeanResult which inherits from Object (ie no declared parent class) and it does not have a ToString method so that inherits from Object. PermCalc gives the following listing which shows a permission request from ToString which means that every class will then require UnmanagedCode as every class eventually inherits from Object.

• SQL Server Excel pivot table

  Hi, I have several pivot tables in Excel that access data to a SQL 2000. We install SQL 2005, we change the ODBC from the 2000 server to the 2005 server. Now when we try to run the pivot tables I've got the following message: "User 'public' does not have permission to run DBCC TRACEON" Any idea on how to fix this problem Thanks, Arty Could you also look in Profiler and see what are the differences between the contexts that are executing the DBCC TRACEON command on SQL Server 2000 and SQL Server 2005. Make sure to select 'Show all columns' for the trace, so that you can see all information available for the DBCC event. I'm interested in columns like NTUserName, LoginName, DBUserName, ...Show All
