Hi, I have two graphs with different amplitudes. How is it possible to compare this two signals? I thought I can write the signals, frequency, hz, time(?) in a field and compare this values then I can connect a LED for the status. But there is the problem with the amplitudes

Hi, I like to ask, if there is someone registered in the discussion forum on the .ni website. Maybe there are other peoples with the same problem. I like to login (I have an account) but then it switches between my login account and the status "ghost". You can see this in the URL. I made some screen shots

Hi! I have still problems with replacing a string. I find an example in the LV help about this - "search string and replace.vi" I built the same code in my vi and test it. But there is no change. The same stings comes out as the string which go in :headbang: So I take the example, made a sub vi and paste it in my code. Second test. I saw how the string goes in, the string was displayed in "string in". Then the character to replace and the new character were set. After this the replaced string was displayed in "string out". But at the end the unreplaced string comes out I will replace a : with a _. In the time/date string I build the time is displayed like this: 09:20. And windows don't like : in a path name :headbang: What can be the problem?!

Oh, I just find an icon which can convert a path to a string I used my builded date and time sting connect this with link strings. This string is able to connect at standard name from open/create/replace a file (there I used <create> but I get a dialog which I don't want)

Hi, I like to create a kind of log file after before my LV programm is closed (only if a failure exists). The first log file was OK, but now I notice that the file names of the created log files must be expedient for later checks. My idea is, give the files a standard name e.g. log error messages. Then add the current date and time to this file name. But how can I manage this? :headbang:

OK, this two options were marked. I will try this if an other pc with LV installed is free. I remember, somebody said this should be marked...

Hi I like to test my code on an other PC, I transfer the code via USB. After run my LV programm all lines were contorted. I'm not able to see the cross from windows to close the application. Everything is contorted. The resolution on the pc I'm developing is 1280x960. The resolution on the other pc is 1024x768. How can I set LV for solving this problem?

I have a question about this attachment. What's this for a symbol with the constant "3"? I don't know this symbol and can't find it :headbang:

Hi, if I write some error messages into a file, can I attach a date and a time? This attachments must be the actually time/date from the error. The error must be comprehensible.

ahh I only want to edit my post

OK

I can't find the proberty PageVIs If I connect thearray index with the proberty node, I get Page, ok, but if I click for the proberties, I can't find PageVis, only page active, page visible.... If I disconnect this I can choosea class ...

Oh, you're right :thumbup: I choosed the local variable zero

Hi, is there a function to set numeric elements blank like for stings the blank string constant?

How to compare is clear, but how to sent the stings back .... I will try to find out something about Bryan's solution

Hi Alex, LTR? Do you have a link for me? Now I'm just happy to have a connection

Hi, ok, now the failure message 66 is off Now I have an connection between my two PC's, I can sent one string from one PC (1) to an other PC (2) :thumbup: My next challenge is to send this string back to PC 1 and there I have to compare these two strings (I must find out if the sting I sent is the same string I received) and make it visible with an LED. But I don't know how to sent my string back. Must I open the TCP connection a second time after reading TCP on PC1? Is it possible to send a string from a PC to an other PC without LV installed and sent this string back to the PC where LV is installed? Or must LV be installed on both PC's?

Hi! Now I have a tcp connection but every time there es failure message: Failure 66: LV: The network connection was closed by a partner. Which partner???? :headbang: I simulated a server like the example simple data server.

Thats funny, we have the same project :thumbup:

Thanks!

Hi! I like to hide some tabs of an index card depending on a radio button. How can I enter this hide property on the index card? Or ins't there any property and I must create a case or an event? I try to put my index card into ab event but there is no help for how to connect an index card (my help said no description available :headbang: )

Hi, I like to know if it is possible to send some data via TCP/Ip with LV. Are there some examples? Must I open one port for every data or could I send three signals over one? (synchro, ttl and audio)
