• SQL Server JDBC Driver setMaxRows documentation error

  The javadoc for statement.setMaxRows(maxROWS) reads: "Sets the limit for the maximum number of rows that any ResultSet object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped. " In fact, it seems that the driver calls set rowcount MAXROWS on the connection. While this superficially will work, if your query manipulates records sets that exceed MAXROWS, the subqueries will also be limited in their size. And this is not what you expect. The javadocs suggest that it is only the result that is truncated. Silently. It seems that setFetchSize is more appropriate. I am using a relatively recent jar (248KB). I hope that somebody finds this useful and that the development team will adjust ...Show All

• .NET Development Problem Making Requests to a non-.NET Web Service

  I'm attempting to utilize a web service written in something other than .NET. (Not sure what it is... probably J2EE.) I grabbed the WSDL via VS.NET (I'm using .NET 2.0, btw) and it created the proxy classes. When I make the request the remote server just returns an empty request body. After poking around a bit I discovered that their example SOAP request and my actual SOAP request differed quite a bit. First, their namespace prefix differed from mine. Their's is SOAP-ENV and mine is of course just SOAP. I assume that's fine. But then it gets more strange. The particular method I'm calling is called makePurchase. My SOAP request, however, looks like: <soap:Envelope ...> <soap:Body> <Purchase> Their example SOAP req ...Show All

• Visual Studio Express Editions Looping help

  I am very new to C++. I need help with a program that I am currently working on. The program is a basic statistical analyser which looks through datasets and find average, minimum, and maximum in the given dataset. I am using a batch file to automatically input the data into the program. The final data looks like this: 8 -5 9 13 -8 16 -11 5 -2 -7 10 0 8 9 13 16 5 10 0 -5 -8 -2 -11 -7 0 0 The idea of the program is to input data until it read a zero. For this i am using a While loops: while (x!=0) at the exit of the loop, the program then prints out the output (average, min, max). This is where I am having trouble. I want the program the continue inputing data from the last zero it finds. Thus I would get 4 different outputs. F ...Show All

• Visual FoxPro MS SQL Server or VFP Database???

  Hi every one, hi MVFPs, I am working with SQL Server database, but I wonder that I've got some big problem with SQL table that has more than 500,000 records. If there are about 50 connections access to that table with select, update,,, task, the SQL will become very slowly and return error message as: ....query out of time,,, or dead lock.... If I work with VFP database, there are about more 100 connections with command "use" the table, and so often tasks to seek, select, update.... but It still work well even if not too fast. And I have a VFP table with more than 1,5 billion records working hard like that. So now I don't know if I will working with VFP database or getting SQL instead because of the more security of usin ...Show All

• Visual Studio 2008 (Pre-release) ADO.NET vNext August CTP is here

  Just curious - why is it that the bits Pablo is working with in the Channel 9 video have a really nice looking visual designer for entity models - and the August CTP gives us nothing but raw XML to play with and no designer What happened between then and now that yanked the designer from the bits As is always the case during development, there are a number of things we have under development/investigation which are not in a form suitable for shipping even in a CTP. The visual entity designer is one of these. We are looking at the possibility of making it and/or other tools available at some point in the future, but we don't currently have any confirmed plans. - Danny ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Question about installing games...

  Hello, I created a small game in Game Studio and it runs fine on my machine. I wanted to install it on my wife's laptop and it won't work.
