problem of current directory

Hello.
How can I force LabVIEW to go to a specific directory on the hard drive? I have a DLL function that loads some .exe files in a DSP, but if (for example) a different directory was previously specified in the file dialog box, then the DLL function fails (locate the .exe files). I tried all kinds of combinations to get the path current vi etc, by running a file of arbitrary commands in the folder I want, etc. None of this seems to work. The DLL (that I can't edit) looks in the same directory for .exe files.

pls help!
Thank you
Neil

You pass a path to the DLL or DLL is looking for the files in the current directory? If you need to set the current directory, a call to SetCurrentDirectoryA in the kernel32.dll module might do the trick. I have attached an example in LabVIEW 7.0 to show what I mean. It has a constant path that you can set for what you want.

  • Problems of file directory

    I'm under 7 Captivate, version 7.0.1.237 on a Windows 7 laptop.  I have problems of file directory.

    If I look at my directory of files using Windows Explorer, I see the following file:

    M04L01040 16/06/2014 21:03

    If I do file open in Captivate and navigate to the location of this directory even I can't see the following:

    M04L01040 13/06/2014 11:35

    I've recently updated to Captivate 6 7 Captivate on the same computer laptop and has not experienced any problems like that with 6. What could be wrong?

    The date two fields are different. One date, which generally corresponds to the date a file was created and the other is update that corresponds to the last time that the file was saved.

    What is the problem you are having?

  • OMB * Plus the command to the list of files in the current directory

    UNIX-based OMB * more customer supports the command 'ls' for a list of the files in the current directory (OS).

    Does OMB non-windows * more customer have a similar command? I tried the two 'ls' and 'dir' without a bit of luck.

    I use the Windows OMB 11.2.0.2 version * more customer.

    Thank you.

    Use tcl commands to get the platform independence, so, for example, you can use
    glob *.
    to list all the files or
    *.XML glob
    for all XML files in the directory.

    See below for details of the glob command
    http://www.tcl.TK/man/tcl8.4/TclCmd/glob.htm

    You can use cd to change directories because I think that the version of TCL used is older and does not support the - directive of the directory on the glob command.

    Hi Joseph,.

    You must first create a directory.
    SQL > create directory

    as '';
    SQL > grant all the Directory public /;

    Now, you must run the command ADB but make sure that the patch has permission 777 for all folders.

  • Problem with current path function screws...

    Hello world...

    Yesterday my application suddenly started to behave in a weird way...

    I have a Sub VI, in which I currently have function of path of screws. I created my app executable. launched and observed the current path of screws gives me some stupid trail all of a sudden.

    It should give me...            Program files\application\app.exe\subVI.vi

    but I'm files\application\app.exe\D:\Application name\sub directory\subvi.vi program

    "D:\Application name\sub directory\subvi.vi", this is the path where the real VI was located on the development computer

    While preparing the exe, I have selected "same as appellant" in the destination domain.

    and you know what?... This occurs only for a project.all other applications are very well... and still I created a test project and tried to reproduce this problem in that. but I'm way in the test EXE project...

    I don't know if I'm the first person to get that kind of weird error with current path of screw...

    I solved my problem at present using the property node: App Dir that I just wanted to know where my EXE is installed...

    Thank you

    Anil

    You're running in one of the new features in LabVIEW 2009. In order to solve the problem where by LabVIEW could end up having tons of screws outside the executable if LVLib or LVClasses was used, NOR changed the internal structure of a LabVIEW EXE to have folders rather than just a flat file list. This is a great advantage if your like me and use classes and lvlibs, but means that the old logic for dynamically calling screws must be changed a bit

    If you want the old behavior, check the advanced settings in the build definition and look for a setting called "8.x File layout" (or something like that).

  • Problem of current drawing of digital entry into PCI-6220

    We have card NI PCI-6220 mounted on card PCI-Raiser in a windows PC mini. We are using 8-channel digital input P1.4 - P1.7 and P2.2 - P2.5 to take a few entries of our entry card.

    When the computer is turned on then everything works well and we get of the digital inputs in Labview. The problem is that when the computer is off the digital inputs on current drawing of early card PCI-6220 and due to this voltage regulator IC on our card entry begins to heat upward.

    This problem occurs only when the PC is turned off, in a State that everything works fine.

    We will be grateful can anyone suggest a solution to our problem.

    Concerning

    Magalie

    I'm not familiar with this part OR special. But maybe there is protection on the output diodes. Usually, these diodes are connected since the entries on the power rail.

    In case the power rail is 0V (or below the input voltage supplied in them), the LEDs will be put and feeding current in the power of the PC rail, attractive and current of your external device. If this unit has a push-pull, HIGH level output configuration there will be excessive current from the power supply where the outputs are short-circuit or almost short as it will be in the configuration described above.

    I have no immediate solution except for additional hardware as the optocouplers, the outputs of your device from the inputs of the unit NOR the decoupling.

  • The problem "your current security settings do not allow this action" when I want to open the swf file in Windows Media Player.

    How to solve the problem when I want to open the swf file in windows media player? There, half year, when I click on a swf file, it could automatically play in Windows Media Player.

    Now when I want to open a SWF with Windows Media Player, it pops up a window "your current security settings do not allow this action".

    How to use watch the video in Windows Media Player swf?

    Hello

    SWF is a file format for multimedia, vector graphics and Action Script in the Adobe Flash environment. Origin with future Wave Software, then transferred to Macromedia and then coming under the control of Adobe, SWF files can contain animations or applets of varying degrees of interactivity and function.

    SWF functions as the dominant vector "animation" on the Web for graphics display format. It can also be used for programs, games by browser commonly, using ActionScript.

    Method 1:

    I suggest open he file in Internet Explorer and check to see if you encounter the same problem.

    Method 2:

    Step 1:

    You can also try reinstalling Flash Player on the system to fix the problem.

    To uninstall a program in Windows 7 refer to the link below

    http://Windows.Microsoft.com/en-in/Windows7/uninstall-or-change-a-program

    Step 2:

    Once you uninstall Flash Player reinstall rear and check to see if you encounter the same issue.
    To download the latest version of Flash player refer to the link below

    http://get.Adobe.com/flashplayer/

    Once you download Flash Player see the link below to install a program downloaded in Windows 7.

  • WebLogic with problem supplier Active Directory Authentication: < DN for user...: null >

    I have a java application (SSO via SAML2) using Weblogic as an identity provider. Everything works fine using created users directly in Weblogic. However, I need to add support for Active Directory. Thus, according to the documents:

    -J' set an Active Directory authentication provider

    I configured an instance of AD LDS (Active Directory Lightweight Directory Services) on a Windows Server 2008 R2. I created the users and a user admin "tadmin" that has been added to the members directors. I've also made sure to set the msDS-UserAccountDisabled property.

    After the restart Weblogic, I see that users and groups in AD LDS are properly recovered in Weblogic. But, when I try to connect to my application using Username:tadmin and the password: <>... it doesn't.

    Here's what I see in the log file:

    <BEA-000000> <LDAP Atn Login username: tadmin>
    <BEA-000000> <authenticate user:tadmin>
    <BEA-000000> <getConnection return conn:LDAPConnection {ldaps://10.20.150.4:5000 ldapVersion:3 bindDN:"CN=tadmin,CN=wl,DC=at,DC=com"}>

    <BEA-000000> <DN for user tadmin: null>
    <BEA-000000> <returnConnection conn:LDAPConnection {ldaps://10.20.150.4:5000 ldapVersion:3 bindDN:"CN=tadmin,CN=wl,DC=at,DC=com"}>
    <BEA-000000> <getConnection return conn:LDAPConnection {ldaps://10.20.150.4:5000 ldapVersion:3 bindDN:"CN=tadmin,CN=wl,DC=at,DC=com"}>
    <BEA-000000> <getDNForUser search("CN=wl,DC=at,DC=com", "(&(&(cn=tadmin)(objectclass=user))(!(userAccountControl:1.2.840.113556.1.4.803:=2)))", base DN & below)>
    <BEA-000000> <DN for user tadmin: null>
    <BEA-000000> <returnConnection conn:LDAPConnection {ldaps://10.20.150.4:5000 ldapVersion:3 bindDN:"CN=tadmin,CN=wl,DC=at,DC=com"}>

      at com.bea.common.security.internal.service.LoginModuleWrapper$1.run(LoginModuleWrapper.java:110)
    
    
    

    So, I tried to watch why did I: < DN for user tadmin: null >. The Apache Directory Studio I have reproduced the ldap search request used in Weblogic, and of course, I get no results. But, change filter only "(& (cn = tadmin)(objectclass=user))" (NOTICE, no userAccountControl), it works; Here is the result of Apache Directory Studio:

    #!SEARCH REQUEST (145) OK
    #!CONNECTION ldap://10.20.150.4:5000
    #!DATE 2014-01-23T14:52:09.324
    # LDAP URL     : ldap://10.20.150.4:5000/CN=wl,DC=at,DC=com?objectClass?sub?(&(cn=tadmin)(objectclass=user))
    # command line : ldapsearch -H ldap://10.20.150.4:5000 -x -D "[email protected]" -W -b "CN=wl,DC=at,DC=com" -s sub -a always -z 1000 "(&(cn=tadmin)(objectclass=user))" "objectClass"
    # baseObject   : CN=wl,DC=at,DC=com
    # scope        : wholeSubtree (2)
    # derefAliases : derefAlways (3)
    # sizeLimit    : 1000
    # timeLimit    : 0

    # filter       : (&(cn=tadmin)(objectclass=user))
    # attributes   : objectClass
    
    
    #!SEARCH RESULT DONE (145) OK
    #!CONNECTION ldap://10.20.150.4:5000
    #!DATE 2014-01-23T14:52:09.356
    # numEntries : 1
    
    
    

    (the "[email protected]" is defined as userPrincipalName in the tadmin on AD LDS user)

    As you can see, ' numEntries #: 1 "(and I can see as a result the entry ' CN = tadmin, CN = wl, DC = in, DC = com ' in Apache Directory Studio interface); If I add the userAccountControl filter I get 0.

    I read the AD LDS does not use userAccountControl but "uses several individual attributes to store the information contained in the userAccountControl attribute flags"; Among these attributes is msDS-UserAccountDisabled, which, as I said, I already have the value FALSE.

    So, my question is, how do I run? Why do I get "< DN for user tadmin: null >"? What is the userAccountControl? If this is the case, should I do a different configuration on my AD LDS? Or, how can I get rid of the userAccountControl filter into Weblogic?

    I don't seem to find the configuration files or in the interface: I don't have that "user of the name filter: (& (cn = %u)(objectclass=user))", there is no userAccountControl.»

    Another difference is that, even if in Weblogic, I put compatible ssl false flag, the newspaper I see ldaps and ldap, I noticed (I don't mean to install something ready for production and I don't want SSL for the moment).

    Here are some other things I tried, but doesn't change anything:

    -other attributes '-FS' were not resolved, so I tried their initialization to a value

    -J' tried other users defined in AD LDS, not tadmin

    -in Weblogic, I added users who were imported from AD LDS into the policies and roles > Kingdom roles > Global roles > roles > Admin

    -J' removed all occurrences of userAccountControl I found xml files in Weblogic (schema.ms.xml, schema.msad2003.xml)

    Any thoughts?

    Thank you.

    In the case of some other poor soul will fall on this issue: I did this job by configuring a generic ldap authenticator.

    I've been struggling with the installation of Flash 11 for more than 2 hours now. I try to install Flash 11 on my Windows 7 x 64 system.

    50% of the progress of the installation, I get the following message: "application already in use."

    I tried the following:

    -uninstalling Flash 10 (that I can not install more than elsewhere) with the Adobe uninstaller tool.

    -Remove the Flash folders.

    -Restart the computer.

    -Close all programs that are running in the background (even Windows Explorer).

    Anyone can help with this problem? She sucks a bit to do not have the ability to look at 90% of the video clips on the internet and a lot of sites.

    I found that interferes with the installation of Flash. There are files in my temporary folder that prevents the installation of Flash. After erasing my local temporary file, I was able to install Flash. So for people who have the same problem and it cannot be resolved by doing a clean installation of live / offline, try to clear your local temporary folder first!

  • loadVariablesNum problem in another directory

    Hey everybody,

    It is a bit strange (for me at least) and I would greatly appreciate pointers.

    I http://www.mydomain.com/index.php Installer that includes / poster http://www.mydomain.com/site.swf

    When I visit http://www.mydomain.com/index.php the site/flash file is displayed correctly

    I also install http://www.mydomain.com/subfolder/index.php that defines two variables and then includes http://www.mydomain.com/index.php

    When I visit http://www.mydomain.com/subfolder/index.php loading of the flash file and him then stops at the point loadVariablesNum usually works (which prevents the swf file to load).

    I would be massively grateful if someone could point me towards what I should search in for this problem that I have tried many things and I am very confused (and I was wondering if it is something completely independent I'm missing because I do not see how this would affect loadVariablesNum!)

    Thank you very much

    Dave

    I can't be sure since I don't deal with this button to include a file to another folder, but it may be a case of not to target the loadVariablesNum tries to access any other file.

    When you load a swf in a web page, this page sets the relative path for what this or that loads the swf file.  Thus, it may be a case where you place the data file in the same folder (relative) as index.php of the subfolder.  Even if the primary php file loads the swf file, the page of subfolder is the operating base.
