Thanks a lot for your kind help! I'll check them one by one! Hey, i2dx, do you have English version of your program?? I only know Chinese and English～～～

My computer sound card is : sigmatel high definition audio codec

Hey, my supervisor asks me to find a method to read and record the sound card. Is there any example in LabVIEW to realize this? Thanks in advance!

Thank you, Aristos Queue It's not very often to get the error. Sometimes my computer was shut down abnormally. Then when I turn on my pc and open LabVIEW, the error will be shown.

Oh, Aristos Queue You're right! The "LabVIEW Data" folder is "Read-Only"! However, the property of the folder will change back to "Read-Only" right after I clear the option. I'm the administrator of this computer... And ther're Log files in the folder!! :headbang: The latest one with information shown below: #### #Date: Thu, Mar 22, 2007 10:09:44 AM #OSName: Windows NT #OSVers: 5.1 #AppName: LabVIEW #Version: 8.2 #AppKind: FDS #AppModDate: 07/27/2006 05:08 GMT .\manager\ThEvent.cpp(116) : DWarn: DestroyPlatformEvent failed $Id: //labview/branches/Europa/dev/source/manager/ThEvent.cpp#4 $ 0x004C6D73 - LabVIEW <unknown> + 0 0x00EF060D - LabVIEW <unknown> + 0 0x00EF077B - LabVIEW <unknown> + 0 0x00EE79FD - LabVIEW <unknown> + 0 0x00CE4192 - LabVIEW <unknown> + 0 0x00CE5922 - LabVIEW <unknown> + 0 0x00CE5BE3 - LabVIEW <unknown> + 0 0x00583D68 - LabVIEW <unknown> + 0 0x00F934C4 - LabVIEW <unknown> + 0 0x00FA71CF - LabVIEW <unknown> + 0 0x005F7912 - LabVIEW <unknown> + 0 0x0055FE62 - LabVIEW <unknown> + 0 0x00C47531 - LabVIEW <unknown> + 0 0x00C497C6 - LabVIEW <unknown> + 0 0x004CCB39 - LabVIEW <unknown> + 0 It's too difficult for me to understand.

Thank you, Michael_Aivaliotis, Can you tell me why the path "C:\Documents and Settings\Workstation 2\My Documents\LabVIEW Data\lvfailurelog" doesn't work?

The error is shown below: http://forums.lavag.org/index.php?act=attach&type=post&id=5255 Does that mean I should change the location? But how? And why the current location did not work? Thanks！

Well, my problem has been solved. I have two instruments and I use two GPIB-to-USB cables... Actually, one cable is enough.

I also encounter this problem. However, I'm using "Rohde & Schwarz" SMU200A. I'm using LabVIEW 8.20 and the driver can be downloaded from: http://www.rohde-schwarz.com/WWW/DOWNLOAD....u_lv8_2_4_6.exe The example I used is the RSSMU Getting Started.vi The VISA resource name is right and the connection is good. However, I get the "Timeout error" which is related to the Initialize.vi SubVI.

I do know why there should be two reads.... However, the tests I do show such conclusion.

Oh, the problem has been solved! I add wait time before the second read part and with enough wait time, I could get the desired string now!! http://forums.lavag.org/index.php?act=attach&type=post&id=5091 And now I want to calculate the average of the total 51 hex values, is there such function offered by LabVIEW?

Even I change the Wait time to 1000ms, I still could only get the "c a" in String indicator 2.... With two read parts, I get nothing~~~~

http://forums.lavag.org/index.php?act=attach&type=post&id=5075 The hyperterminal is shown as above. However, I do not understand much about "display type".... I did not use the SubVI in this event so that I can get the string without previous information. And there's nothing shown in String Indicator 2 if I read the COM Port twice. http://forums.lavag.org/index.php?act=attach&type=post&id=5076 But it's strange that if I "Highlight Execution", the hex string what I want will be shown in the String Indicator 2. Why, why, why... I have no idea about "endchar enabled", the SubVI is also attached.

Thank you for your help!! So now I know how to convert the string to an array. However, the first problem is still there...I don't know how to get the exact hex string. http://forums.lavag.org/index.php?act=attach&type=post&id=5071 As shown, I could only get the "c a" command. It seems the hex string value will be received until next Read from the COM Port. http://forums.lavag.org/index.php?act=attach&type=post&id=5072 And if I replace the SubVI with detailed write and read implementation, I still could only get the "c a" in String Indicator 2 http://forums.lavag.org/index.php?act=attach&type=post&id=5073 It's so difficult to get the desired string from the COM Port...... And without the string, I could do nothing:(

Hi, all I'm writing a program to test a board. And the front panel is shown as follows: http://forums.lavag.org/index.php?act=attach&type=post&id=5056 When I click the "Start ADC" button, the computer will send a command to the board and the board will return both the command and hex string with 50 values. As shown "0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE...."(they're the same as a testing) My job now is to take out the 50 values and calculate the average of them. It seems there's a tool called "Hexstring to number", I think I could use it to take every element out(not include the "0x"). However, I could not get the "0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE0xC7CE...." in that button event as shown in the right string indicator. Only the command "c a" was received at that stage. Below is the block diagram of the "Start ADC" event: http://forums.lavag.org/index.php?act=attach&type=post&id=5055 As I did not know how to get the hex string, I could do nothing to get the average value..... Anyone could give me some tips?? Thanks a lot! The original VI is aslo attached.
