I want say read tags from PLCs and log in database. This operation isn't tima comsuming because i use only 2% of CPU time. Wich version of LabVIEW are you using? Update rate, deadband ... . I want know what you doing different, to make it work. In attached image you can see the system layout.

Hi, I'm developing a application thats need read and log a large tag database at period of 1 second. My system have actually 1200 tags and when I try to increase the number of tags my system slowdown and not update at requested period anymore. I'm using NI OPC Servers to read data of 4 different PLC's. In the SVE I've created an IO Server to bind variables and all variables are located in a single process. All variables are logging alarms and data. The Log Deadband and Update Deadband are set to 0. My machine is a DELL Precision T5400 with Dual Intel Xeon Quad Core with 4GB of RAM and Windows XP Sp3 installed. LabVIEW 8.6.1 Bruno Costa Automation Enginner

Many thanks Yair Bruno

This function accept a sql statement with parameters like format into string and you can resize this function to the number of input parameters. The output data can be a cluster or an array of cluster defined double clicking on function. How to use: Wire db connection input. Wire sql statement with parameters like format into string function. Resizes the function with the number of parameters into sql statement, If the sql statement produces data output, double click on function to Edit columns of data outuput. Requirements: Database conectivity toolkit Scripting tools This function isn't 100% complete. It's need to complete some abilities and code improvements. If anyone want help me, be welcome.

Hi, again Its possible intercept the messages sents to the app and send a response without app known See this article on CodeProject Site: http://www.codeproject.com/KB/dialog/messagehandling4.aspx Bruno

QUOTE (clementgirod @ May 11 2009, 12:23 PM) Hi, You must be able to handle windows messages, Whe a window is inactive and you click inside it, the OS sends to the window the message WM_MOUSEACTIVATE and the window must reply this message with MA_ACTIVATE, MA_NOACTIVATE or MA_ACTIVATEANDDEAT. In your case you must use MA_NOACTIVATE. I dont know how to disable alt+tab too. Bruno.

Hi, If you are using MS Windows you can do this. You must make 2 Windows API Calls First, you will get the handle of the window with the function FindWindow And after, you call the function SetWindowPos with thew option TopMost See on MSDN for the parameters of functions
