• .NET Development NoNullAllowedException on an Identity column in SQL

  Hi I have created an SQL database with two columns the first is an identity. When I try inserting a new row I get a NoNullAllowedException on the identity column. DataRow newRow; newRow = infoDataSet.infoTable.NewRow(); //newRow[0] = [int]; as an identity column I am hoping this is autogenerated newRow[1] = "Any Text"; infoDataSet.infoTable.Rows.Add(newRow); // NoNullAllowedException occurs here! infoTableAdapter.Update(infoDataSet.infoTable); Any help appreciated - cheers Hi, You are trying to insert a null value in the identity column (and identity columns don't allow this kind of values). I'm not sure, but I think that if it is auto-generated (if you defined that in ...Show All

• SQL Server SQL Server Integration Services - Stop large number from being converted to exponential

  I am importing a text file with a column (serial numbers) with alphanumeric data, some mixed and some only numeric. The very large values that are all numeric are being converted to exponential when I run it thru an import package in SQL Server Integration Services (2005) Ex. 4110041233214321 --> 4110040000000000 (displays as 4.11E+15) In the past I dealt with this by importing the text file into Excel and changing the format of the column to number. This works even when many of the values contain alpha characters. I am not sure how to accomplish this same thing without going thru Excel. If you have any ideas on this I would be happy to hear from you. I am importing the text file into a sql table. ...Show All

• Visual Studio 2008 (Pre-release) DataContract vs persistence model - Guidance needed

  Hi forum I really need some architectural guidance on the above subject. Here's the scene and how I chose to implement it so far: I have layered server, which host WCF services. These are the layers: - WCF Layer - Business layer - Persistence layer The persistence layer is not the database, but merely a repository of method, which operates on the persistence model. The persistence model is exposed with a OR mapper (Vanatec OpenAccess) and is highly navigable in respect to associations between persistent classes. The WCF layer is the transaction boundary, which has the role of calling the right methods (in the right order) in the business layer. So you can say that the WCF service methods controls the steps involved in each "business t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Bullet Fires Only Once--Never again

  Hi there, Like everyone else here, I have a problem. Basically, whenever I fire a bullet, it will fire only once. It fires just fine, only, when I hit space to fire a second bullet, a second never fires. Or any other number. So, I think this is all the relevent code for the bullet: void FireBullet() { for ( int x = 0; x < bulletnumber; x++) { if (BulletVisible[x] == false ) { BulletVisible[x] = true ; BulletPos[x].X = PlayerPos.X + 40; BulletPos[x].Y = PlayerPos.Y + 32; } } } Another section where there could be issues, this time in Draw(): for ( int x = 0; x < bulletnumber; x++) { if (BulletVisible[x] == true ) { SpriteBatch.Dr ...Show All

• Visual C++ partial serialize/deserialize a structure

  Hello everyone, I have a large number of strcture instances, the I can not have all of them in memory. So I have the idea of serialize/deserialize partial of them to/from disk. The operation I need on these structure instances is to enumerate elements one by one, and I want to provide applications which use this interface to enumerate elements be transparent to how and which parts of structure instances is written/read to/from disk -- and the application only will feel read from memory. I am wondering whether there are any samples/tutorials to make a reference thanks in advance, George Enumerating elements won't be possible, unless you're using C++/CLI and reflection.

• SQL Server keeptogether applied incorrectly on pdf export

  I've got a strange issue on a SRS2005 report.  I've searched the forums for something similar and found a couple of questions but no answers.  Any help anyone can provide would be greatly appreciated. So, the report has a list with an embedded list.  List of categories then list of detail items inside.  On both lists keeptogether, pagebreakatend, and pagebreakatstart are all false.  But when the report is exported to pdf it behaves like keeptogether is on for the outer list, creating page breaks after the list if the next one won't fit on the same page.  Which creates a lot of needless white space and makes the report several pages longer than it needs to be. I've checked for report width and height, mar ...Show All
