• Visual Basic Making settings mandatory and trusting locations

  Hi everyone, I'm working in a 300+ workstation school site which has 1500+ users. I have installed VB 2005 and setup the settings that I want them to have. How can I restrict Visual Basic so that it's 'profile' settings stay the same for each user after they log off and without an error message saying that it 'can't be written to I have tried restricting the settings file and it gives me an error. Is there a way of turning off the 'auto' saving function of the settings file Secondly, We have redirected all the user accounts to a mapped network drive on the server - ex H:\ . When I make a new project on H:\, it states that it is not a trusted program location... How can I make it so that H:\ is trusted Thanks ...Show All

• SQL Server Select customers who havnt made orders

  Using the northwind database, how do I select the cutomerID of customers who havnt placed an order. is it something like this select Customers.CustomerID FROM Customers INNER JOIN Orders ON Customers.CustomerID <> Orders.CustomerID and how can I display the customers who HAVE made orders alongside customers who havnt made orders. Thanks in advance. Using EXISTS/NOT EXISTS is the best way and straight forward. NOT IN will have problems if there can be orders with NULL CustomerID for example. Ex:   select t1.i from (select 1) as t1(i) where t1.i not in (select t2.i from (select null) as t2(i))   The query above will return NO row when it should return 1. With NOT ...Show All

• Visual Basic Troubleshooting with IDE - Unable to open search!

  Hi. I have Visual Basic 2005 Express Edition and I am having problems with the "Search" option, where you type in Keywords and it searches on 4 different websites / places including my on-board MSDN. It has worked before, in the past, and has been very helpful... But lately it will not open when I try to start it. When I click on the "Search" button at the top it gives me this message box: "The type initializer for 'Microsoft.VisualStudio.CommonIDE.Help.Sylesheet' threw an exception." and that is all that it tells me. I have no idea why it says this and will not open. I have also tried reinstalling my software and that did not help a thing. Thanks, I hope you can help. -Joe M. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. [IronPython] MS.Xna.Framwork.Components missing?

  Hi all, I've played around with the starter kit in C# for a while, and I really enjoyed what XNA can do, but frankly, I'd much rather tinker around in Python. I've been looking around, and I've found many, many code snippets from the August-September time period of "demo games" in IronPython, including this one here on MSDN: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=682285&SiteID=1 However, all of these snippets reference Microsoft.Xna.Framework.Components, which my IronPython interpreter insists does not exist. I've tried exploring the library throught the GSE's Object Browser, but I can't find any general equivalent. Has the library been changed since August/September Does it "make sense" that I'm ...Show All

• SQL Server Transactions in triggers

  I have an AFTER trigger which responds to a table update process. Within this trigger a separate stored procedure is called which does some additional processing. The problem is that if this inner stored procedure fails, for whatever reason, the entire trigger and the initiating update also rollback whereas I want the update to commit. I have tried using various combinations of SAVE TRANSACTION etc but each time I get messages similar to ' The current transaction cannot be committed and cannot be rolled back to a savepoint. Roll back the entire transaction.' Does anyone have any ideas I understand that - however what I'm not sure about is what is making this an uncommitable transaction Is it the ...Show All
