• Windows Forms How do I access the main form?

  Hi! I've got two forms, MainForm (which is my main form) and LoginForm. And I would like to be able to get access to a method in the MainForm from the LoginForm. How can I achieve this If it helps, my main method looks like this: static void Main() { MainForm myMainForm = new MainForm(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(myMainForm); } Thanks in advance. The most appropriate mechanism is to expose a property off your global application object that contains a reference to the main form. It would be set in Main before calling Application.Run . Another approach would be to expose a static method off the Main ...Show All

• SQL Server SQL Server Express setup question

  Hi, I just installed the Express version locally and then tried to simply connect to the Northwind database from a .aspx web page. I get the following: Error reading the database. An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Do I have to do anything for setup Thanks, Eric Okay I just found out that sample databases are not installed by default in SQL Server Express. So I will either download Northwind or not. Have a go ...Show All

• SQL Server Process task hangs running bcp

  We are attempting to use Microsoft SQL Server Integration Services Designer Version 9.00.2047.00 to run a BCP command from a Process task. We are able to do so without a problem when running it interactively, but when run as a SQL Server Agent job the bcp process never completes and the job hangs indefinitely. We also tried using a Script task for this, with the same result. Has anyone else run into this problem Thanks, Ron We stumbled upon the solution for this, but it does seem that a glitch in SSIS may be the root cause. When running BCP in a Process task, the path to the BCP executable must be provided. When running a package interactively a UNC path name to bcp.exe works fine, ...Show All

• Visual Studio Team System Getting revision number from teambuild build number

  Hi all, It seems that TeamBuild defines the buildnumber for a given build in a manner similar to "20060531.13". We would like to use this information when updating the AssemblyInfo.cs files. Namely, to use the 20060531 part and the "13" part in the AssemblyVersion build and revision fields. We are already using the AssemblyInfo task, but we see that it maintains it's own incremental numbers, which are not related to the TeamBuild incrementals, which means that are Assembly versions will not tie in with the lables applied in TeamBuild Is there any properties other than BuildNumber that would give us separately the 20060531 and 13 parts so that we can pass them into the AssemblyInfoTask Sincerely Pete ...Show All

• SQL Server Which SQL Product? Everywhere or Express

  We are building a system that has mobile clients (laptop with XP and tablet with XP). These clients have data moving back and forth to a centralised n-tier server based system. The communications is proprietory and are very low bandwidth (5 KByte/sec). We've decided that the best approach to handling both the reference data (ranging from trivial to a complex list of items - about 2 million rows) and the day-to-day operational data is with a database product rather than attempting to handle it ourselves within code. The question is - what SQL platform to use SQL Everywhere seems to be a fairly good choice except that it does not seem to support stored procedures. SQL Express is another possibility but there are concerns about the size ...Show All

• SQL Server Strange bug with intellisense...

  Hi all, I've got a strange bug with VS.NET and SSRS. Whenever I build my solution and it automatically deploys the SSRS reports to our report server, my intellisense stops working and I have to restart VS.NET to get it back. It only happens when the reports are automatically deployed. It doesn't happen if a solution has no report project. Any ideas as to what I can do to fix this Regards, Stephen. Still having this problem and its driving me nuts! Anyone know if there's anything that can be done to stop it Regards, Stephen. ...Show All
