• Visual C# how to give online updations for My own software?

  I have done one desktop application in visual c#, i want to give online updations for that software . i need full flow and coding for this. there are multiple ways of doing what you are asking but no doubt ciickonce would be the most appropriate way of updating your application. I have done previously (this was for .NET 1.1) a webservice which checks for updates on the server based on what my client application has sent in terms of details for itself, so when the webservice looks at the details sent from the client, it will then try to go through the files on the server to find an update for the client software, if there is one then it will send it down the wire to them, the client then accepts this and writes data to disk and no ...Show All

• SQL Server Carriage return in header of Flat File Destination

  I'm trying to create a flat file that has a header like: /INST=-1 /DELIMITER="," /FIELDS=FIELD1,FIELD2,FIELD3,FIELD4 /LOCATION=100 data,data,data,data data,data,data,data where 'data' represents the data written out by the data flow process to the flat file destination. This actually turns out quite nice except that when I place the lines that start with '/' in the header box for the flat file destination the carriage return doesn't get written correctly after each line and I end up with an unrecognized character when I open the file in a simple app like notepad. I've tried using different encodings for the flat file connection, but to no avail. It is also interesting to note that when I close the package and reopen it the ...Show All

• SQL Server Different execution timing

  I'm using SQL 2k. I wrote a query using the query analizer and tested it before turning it into a Stored Procedure. It worked fine an the execution time was acceptable (25 secs, since there was a lot of data to analize) When I executed the recently created stored procedure, the execution time happened to be three or four times higher. (1 min, 38 secs) It was the exact same code, i was logged in the same database server, the parameters were the same in btoh cases. So, my question is as follows: Why is it that executing a script and executing a stored procedure with the exact same script differ so much in timing Can you post some sample code Most probably you parameterized the values in the ...Show All
