However, if i try to use the graphics sctream write as below, it does not do as expected. The input is not written corrently into the ...Show All

• SQL Server putting dbo explicitly in select staetement

  I have witten a lot of stored procedures in my project where I did not put dbo before the user tables.My colleague told me that I have to put dbo for all statements other there could be a problem. Any thought , Please assist. I've heard it said that not including the schema owner (usually DBO) on your object prefix can result in a "Compile lock" against your stored procedure while the client determines whether there is an object in existence for its own schema. In this situation, multiple users executing the same stored procedure would suffer from a queuing effect as each would place a compile lock on the procedure (or statement). That being said, I've never been able to repro this ...Show All

• Visual C++ Compiler Crash

  OK I know I shouldn't have written it, it was a result of some slow responses on the machine that a class name got replaced by a bracket, and I;ve thrown away a lot of unnecessary stuff however:make a file containing typedef struct {} (; And the compiler will crash. .Net 2005, I haven't tried it on 2003 or Team System.

• .NET Development Sharing wizard-created datasets in a solution

  Hi there, I've created a solution that has multiple projects in it.These multiple projects compiles to become .dll dependency files that is used by my application. I've then used the datasource wizard (vs2005) to convert a large access database to a SQL Express dataset, and placed in under my main application. I have been doing work on it for many months now. All was well until I realize that I need to use some of the tables from that dataset in those dependency dlls as well. However as they are under a different project (or namespace ) , I can't seem to use them. 1. Is there a way we can share the dataset between projects which is in the same solution I tried copying the same dataset into another project and it came up with al ...Show All

• SQL Server strange problem with SQL Server CE 2.0

  recently I am enhancing an PPC application using VS 2005. I decide to use sql ce 2.0 cuz the old system is using this version. I am using the SqlCeEnging to create a new database, and create two tables: TableA and TableB. Inside the two tables, there are few fields without any primary key or index. Of course I dint insert any data so far. Below is part of my coding. query="Select * From TableA Where Con1= And Con2= " SqlCeCommand cmd = new SqlCeCommand(); cmd.Parameters.Add("@Con1", SqlDbType.Float); cmd.Parameters.Add("@Con2", SqlDbType.Float); cmd.Parameters["@Con1"].Value = con1; cmd.Parameters["@Con2"].Value = con2; ...Show All

• Visual Studio Express Editions ALT+F4

  Is there a way to stop ALT+F4 working on a form If possible I would also like to stop CTRL+ALT+DEL working as well. Thankyou Jeremy6996, not the solution i was hoping for but it works fine. Thankyou to everyone for their input on this topic. I relalise that it may have seemed a bit odd to want to disable alt+f4, but if i were making some kind of application to prevent people using their computer as it should for malicious purposes i would not post in a public forum and besides i would have no idea how to execute such a task and i would not want to do it in the first place. I also realise that nobody knows the context in which the program will be used or how good my knowledge of vb is, so i see the cause for suspiscion. Howe ...Show All

• SQL Server Connecting to SSAS on workgroup W2K3 server using SQL Server Management Studio...how?

  Hi All, I'm trying to connect to SSAS on a workgroup (i.e. non-AD) Windows 2003SP1 server from my XPSP2 PC, using SQL Server Management Studio and/or Visual Studio, with no luck. I have set up SSAS to accept anonymous connections, firewall is off, no anti-virus software, etc. I have added 'Everyone', 'NT Authority\ANONYMOUS LOGON' to the SSAS 'server' role (I don't care about security at this stage). I can connect to SSAS from my PC via code , though I have found out by trial-and-error that I need to specify a connection string that includes a User ID and Password; e.g.: "Data Source=sandbox; Provider=msolap; Initial Catalog=Analysis Services Tutorial;User ID =some_user; password= password ;" When I try to connect ...Show All

• Visual Studio Team System tfpt treediff - I'm missing "Get specific version..."

  Hi, Using the treediff feature in tfpt, could often be done with the purpose of detecting files, deleted by mistake in the local folder. This is nicely detected, but to get the missing file from the server, "Get latest" isn't enough - you have to "Get specific version..." and force the get from the server. It would be nice to have this command in the treediff view! Regards, Carsten Upon further investigation, we feel that Get Specific Version is nice to have but Get Latest Version is much more often used. In the spirit of keeping TreeDiff simple, we'll refer that functionality back to the Source Control Explorer. Thank you for your feedback. -Tan ...Show All
