• SQL Server Need to convert NULL values to 0, (zero) in order to perform math calculations

  Using a reporting services model/report builder we have two related tables: - Fundings, (parent) - Draws, (child) Report Builder reports that subtract "Total Fundings.Amount", (which is SUM(FundingAmount)) from "Total Draw Amount", (which is SUM(DrawAmount)) to get a balance work as expected except when there are no Draw rows, in which case a NULL is returned. Obviously we want to convert NULL values of "Total Draw Amount" to zero so that when subtracted from "Total Fundings.Amount" the correct value is displayed. I've searched for a function similar to COALESCE (Transact-SQL) in report builder but found nothing. Can anybody help me with this Thanks Bruce ...Show All

• SQL Server Member.FetchAllProperties Error

  I get "System.NotSupportedException: The method specified is not supported by the current provider." AdomdClient v8, VS 2003, SQL Server 2000 What's the cause of this and is there any way around it Hi Mary. Thanks for this. It worked. We used the second technique because we need to be generic, i.e., we don't know in advance what user-defined properties will be available. But here's another question. Calling Member.Properties gives e.g., Property Name: MEMBER_KEY, Property Value: 13 Property Name: IS_PLACEHOLDERMEMBER, Property Value: False Property Name: IS_DATAMEMBER, Property Value: False ... Property Name: Allow Input, Property Value: 0 The last one here is one of our user-defined properties. The previous ones are the ...Show All

• Visual C# security: password encryption

  hi, in my winows application i'm connecting to database. I don't want to embed the user name and password to the code. i want to take these from a parameter text. So i have to encrypt the username and password before writing to parameter text, and then while connecting database i will decrypt them. Could you suggest me an algorithm or technique... thnx.. Hi, I'd propose not to put too much effort into it because the bad guy just would need to put a network sniffer on the wire to get the cleartext password when you login to the database. Thus, a simple way is to put the username/password information into a textfile which you protect using windows access rights. Encrypting username/ ...Show All

• SQL Server looping through table tom exec an SP many times

  Hi, If i have an SP called mySP that accepts one parameter @param If I have a table of paramaters with only one column like this: Param1 Param2 .. ParamN How do I do if I want to execute the SP on all the table fields: some thing like this: Exec my SP 'Param1' Exec mySP 'Param2' ... Exec mySP 'ParamN' I want that automatically since the parameters are going to be in a table called myTblParams Notice that I don t want to pass all the parameters to the SP just once but only one value each time I execute the SP since mySP ccepts only one parameter.

• Visual Studio Express Editions How do I plot a graph (with x and y axis) on my form?

  Hi, how do i plot a graph (with x and y-axis) on my form UGH.... About a week ago, my motherboard died and I've ordered another one. Meanwhile I'm running on a 9/11 vintage motherboard, with 1/2 gig of memory. I think this board just corrupted my C# templates and I can't start a new c# project. Normally that wouldn't be a problem because I could uninstall c# and reinstall it and everything would be fine....except my DVD drives are SATA and SATA wasn't around when this motherboard was made, so I have no DVD drives. What I do have is a working copy of this in VB..... If that would do any good and the architecture of this sure can be adated to real time. ...Show All
