• Windows Forms MDI Parent Menu

  How can I access and disable/enable an item in the MDI parent menu I displayed a mdi child after clicking the menu from the parent and wants to enable the menu that has opened it once the child form has been closed.

• SQL Server SQL Server CE 3 Constraint Problem

  SQL CE 3.0 I am trying to add constraints using SQL statements but get an error saying that the constraint would cause a cyclical reference. The same statements work with SSCE 2.0 Eg CREATE TABLE A(pkA integer NOT NULL CONSTRAINT pkAx PRIMARY KEY); CREATE TABLE B(pkB integer NOT NULL CONSTRAINT pkBx PRIMARY KEY, pkA integer NOT NULL, CONSTRAINT fkBA FOREIGN KEY (pkA) REFERENCES A(pkA) ON DELETE CASCADE ON UPDATE CASCADE); CREATE TABLE C(pkA integer NOT NULL, pkB integer NOT NULL, CONSTRAINT fkCA FOREIGN KEY (pkA) REFERENCES A(pkA) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT fkCB FOREIGN KEY (pkB) REFERENCES B(pkB) ON DELETE CASCADE ON UPDATE CASCADE); I dont see that the foreign keys should cause a cyclical reference problem.

• Smart Device Development Pocket pc application using Access 2003

  Hi there, this is my first ever post on a forum so please be nice if i get stuff wrong. I am wanting to develop an application for a Windows Mobile 5.0 device using visual studio 2005 but i want to store data on the device using pocket access. Can anyone tell me if this is possible or whether i am 'forced' to use SQLserver The reason i use the word "forced" is that all our software is written in vb6 and stores data using MS Access. The application i am wanting to develop needs to ultimately merge the data with the existing ms access databases. (There are only a limited number of people access these databases so i dont feel any need to upgrade to SQL just yet - If it aint broke dont fix it!!!!) I've found thread ...Show All

• SQL Server Help with SQL Server 2005 and IIS 6.0

  Hello, I am having problems with my system configuration. I am trying to access a SQL Server 2005 database from a C# .NET web page, but I keep getting this error, " Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'". I am using windows authentication. The SQL Server resides on one server and my web server is on a different server. If I run the both the web server and SQL Database from within the same server it works fine, the problem comes when I separate the servers.

  I've seen on links on several pages where there was supposed to be additional information about how goverment entities can or are using Virtual Earth, but most of them lead to something other than what I was expecting.

• Visual Studio 2008 (Pre-release) What's the difference between a template and a style in WPF?

  Please help me to clarify that or show me the reference. Thanks:) Cool, a debate. ok, I should've clarified that with a "can". A style can contain a template as the template is one of the properties in the Style. I guess you can leave out any property you like really, but a complete Style contains the Control Template. If you draw a button in Expression, right click and go to Edit A Copy Of The Style, then the Style generated will contain the Control Template. So the original questioner could probably mark this post as the answer ...Show All

• SQL Server Extremely Poor Performance - Identical DB's but very different performance

  Hello Everyone, I have a very complex performance issue with our production database. Here's the scenario. We have a production webserver server and a development web server. Both are running SQL Server 2000. I encounted various performance issues with the production server with a particular query. It would take approximately 22 seconds to return 100 rows, thats about 0.22 seconds per row. Note: I ran the query in single user mode. So I tested the query on the Development server by taking a backup (.dmp) of the database and moving it onto the dev server. I ran the same query and found that it ran in less than a second. I took a look at the query execution plan and I found that they we're the exact same in both cases. Then I too ...Show All
