• SQL Server A "not in"-lookup?

  Hi, This may be an easy one, but I can't seem to crack it: What would be the best way to implement a "not in"-loopkup. I want all the rows in my dataflow, where the key is not found in a specific table, to proceed in the data flow. I could modify my data source only selecting the rows I'm interested in. However I don't like this solution as it is not very transparent. I could also just use a Loopup transformation and then just use the Error Output for the rest of the flow. I don't like this solution either as it is a reverse approach. Is there a third, and better, solution or will I have to go with one of the two above Regards, Sune ...Show All

• Visual C# Problem with LRC-Checksum

  Hello, I try to get an LRC-Checksum (XOR of each string) of the following hex 41 30 31 54 30 30 30 30 30 30 30 30 30 30 30 31 30 39 39 34 35 30 30 03  and my result is 05 which seems to be wrong. I calculate it with string GetChecksum( string sentence) { // Loop through all chars to get a checksum //char Character; int Checksum=0; foreach ( char Character in sentence) { // XOR the checksum with this character's value Checksum = Checksum ^ Convert .ToByte(Character); } // Return the checksum formatted as a two-character hexadecimal return Checksum.ToString( "X2" ); } This string will be sent over RS232 to anot ...Show All

• Visual Studio Team System Check for true sentence

  I want to know how can I check a sentence like that on the code: if(isInt == true) I mean, I want to know if that sentence exist on the code... Rodrigo, What are you tried to achieve Are trying to determine the unnecessary comparision to true For example, you would fire on the following: if (isInt == true ) { } but the following would be okay: if (isInt) { } If so, then this is not possible. FxCop analyzes the end binary and not the source code, and both conditional statements above compile into the same IL. If this is not what you are trying to do, can you provide more information ...Show All

  Hi, if ClickOnce was a person i'd certainly give it a knock out right now ... I'm so frustrated with that thing, using it since the early alpha bits and always having problems with it ... now in beta 2 it doesn't work again the way it's supposed to. The specific problems I have right now are: As soon as I activate ClickOnce security settings, setting them to full trust and debugging the applicatin with this permission set, as soon I try to launch my application I get: "This application has failed to start because the application configuration is incorrect. Review the manifest for possible errors." In the EventViewer i get 4 SidebySide err ...Show All

• Visual Studio 2008 (Pre-release) Why the reverse German-like syntax?

  Why do the LINQ queries have to look like a SQL query in German   If you are trying to make it easier and are adding SQL-like keywords to the language, at least keep the ordering the same as SQL. The way this is, I have to know C#, SQL for triggers and stored procedures, and LINQ for the in-code queries.  I don't see how this is going to make my life any easier. > .... why then has VB decided to do it the wrong way This would hardly be a first for VB and cannot be taken as a guide for what C# should do.  I am not on the team, and am not from MS, but what's clear to me is tha ...Show All
