I'm trying to access Window Handle (HWND) in Labview. This is an argument of a DLL. Also I need to get a pointer of an image buffer.
Call library function in Labview:
=================================
Hi all,
I'm trying to access a DLL using Call library function in Labview.
1) I have problems in obtaining the window handle (hDC) of an object in Labview.
2) Also to get the pointer of an image buffer.
thanks

I'm trying to do something similar right now and coming to the same problems. I am trying to get the image from a Nikon DXM1200 camera that is mounted on a microscope. It has its own commands and capture card and is not playing well with the imaq stuff. I am using their SDK in an effort to get the images into LabVIEW.
As I said, I am having the same types of problems. I managed to wrap everying into a dll and into a .net assembley, but I have been unable to figure out a way to get it into LabVIEW. I can call either of these things from LabVIEW to make an image capture. But, I have been unable to transfer that image into LabVIEW. I also have been unable to get enough windowing information to get the information into LabVIEW.
I am not sure what Code Warrior is doing, but here is why I have been tracking this thread with great interest.
Thanks for the thread,
Bob
You might want to look at http://www.hytekautomation.com/products.html. They have a Nikon interface for LabVIEW and since you already have the SDK, the issue mentioned on their site won't be a problem for you. It is for sure much more cost effective to pay them some money for that interface than trying to develop an interface yourself. The issues are quite involved and even if you knew quite some stuff about LabVIEW memory management and its internal C programming interface (and you can get quite some information from looking at the NI-IMAQ VIs too, eventhough they are anything but a nice example for good programming style), it is a work counting into weeks to get it done right.

I just updated my Mac to the new op system and when I tried to open my Ai it gave me this message, "To open "Adove Illustrator CS5.1 you need to install the legacy java SE 6 runtime." I updated my Java to 8 and it still won't open. I tried to update my Ai to 11...it won't update.
Steven,
The right way/order is to update the OP, then reinstall the applications.

Referred to start menu whe trying to access windows updates
When I try to access windows update from Firefox browser I am sent to start menu and windows update for windows 7. I am trying to avoid this for security sake. Windows is having the most problems and also google on security issues which is why I am using Firefox forinternet security. Not even the Norton my supposed security I am paying for can provide security for yahoo mail or windows. Yet I am forced to access under windows update. Am I secure if I leave the firefox browser up when I access windows update from my start menu? Or is there a way around this?
Hi @khamm56 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Notebook and issues with screen flickering and freezing. If the Notebook works in safe mode with no issues it is either driver or software related.
Can get to safe mode with command prompt?
F11 upon startup choose safe mode with Networking.
Then you can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook. I recommend doing this for at least 2 weeks prior to this happening.
When performing a System restore please note remove any and all USB devices. Disconnect all non-essential devices as they can cause issues.
I hope this helps.
Thanks.

Trying to access Windows 2003 Server share with Mac OS 9.04
Hi
I cannot connect to a Windows 2003 Server share on my 2003 domain. I can access the share with my MacBook (10.4.9) & my G4. I have File Services for Mac installed & can ping the server from all OS 9 Mac.
Can anyone give me some tips?
MacBook AdministratorHow are you trying to connect to the server? Via AppleTalk or IP? (What utility are you using to ping the server from the Mac OS 9 machine?) Since you're not providing any information about error messages you're receiving or the symptoms of your problem I can only provide the following information.
If you're selecting the server from a list in the Chooser and clicking the OK button then the connection should switch to IP automatically. Make sure your Mac has TCP/IP enabled and is receiving an IP address or that you have an appropriate IP address hard-coded. You can try forcing an IP connection by entering the IP address or DNS name of the server in the Chooser rather than selecting it from the list in the Chooser.
Or you can try forcing an AppleTalk connection by selecting the server in the Chooser and holding down the Option key as you click the Connect button. If you're asked to enter your name and password then you're communicating properly with the server. This is, however, a very slow connection compared to IP.
Finally, be sure you update to the latest version of Mac OS 9, which is 9.2.2 <http://docs.info.apple.com/article.html?artnum=75288>.
Hope this helps! bill

Time Machine Backup Trying to Access Windows Exchange
I have an iMac that used to have access to a Windows Exchange email account. That email account has now been deleted as it caused too many conflicts. However, when I now access Time Machine my iMac tries to reconnect to the old Exchange server with an old password and that locks me on the Exchange email account as I assume it keeps attempting multiple logins. Unfortunately I dont have control over the Exchange account so I have to have that reset everytime I use iMac Time Machine. Is there ay way around this? Many thanks

Access Denied when trying to access shared folders on the server with administrative privileges
I have problem accessing shared folder on the server machine from Windows 7 machine even if I try to access it with administrative privileges (server Administrator account). I will try now to explain better my situation.
In my company, we have small network infrastructure with one main server machine (HP ProLiant server) with Windows Server 2012 R2 installed and couple of desktop machines. The network is administrated by me.
On Windows Server we have installed and setup DHCP, DNS, Remote Access and Routing, File and Storage and Active Directory services. Desktop machines are having Windows 8.1 Pro, Windows 8.1 or Windows 7 Home Premium installed on them. In Active
Directory I have created domain, User groups and Users for employees in my company and so far, I didn't added desktop machines to the domain.
Also, I've created one folder on the server which should contain different projects data for network users and I have set access permissions and security for this folder and shared it on the network (I've added couple of users to one user group and I
gave Full control to this group over this folder). When I try to access this folder from network, I've been asked for login credentials (normally), where I just type in one of users username and password who has been given access permissions to (who is member
of group with full control over the folder). From Windows 8.1 Pro and Windows 8.1 machines I can access and work on this folder without any problems.
The problem comes with Windows 7 machines. On Windows 7 machines (I have also tried this with Windows 7 Ultimate in VMWare) I can access server, I can see its shares, but as soon I try to access folder I've created for projects, I get Access Denied message
with request for User login credentials. Whichever user account I use (even servers main Administrator account) I keep getting this message over and over and I'm unable to access it at all.
I have also tried to access the server through VPN (from local or outside) but I'm getting the same error again. Also I've tried to add these Windows 7 machines to the domain and login with domain user but the result is the same. Turned off both firewalls
(on server and desktop machines, which I know is unnecessary, but lets try it), still same case. I've tried couple more things with registry editor on desktop machines which I found on different forums and websites but still no luck. And now I don't know
what else I can do.
Does anyone knows what's the problem here, have I set something wrong, have not set something I should?Hi MeipoXu,
thanks for your response. I will first answer on your question.
Yes, the main issue is that we can see the folder when we access the server but we cannot access its contents from Windows 7 machines. I have tried on two machines, one with Windows 7 Home Premium version and the other one with Windows 7 Ultimate version
and the situation is the same.
As you recommended, I've checked Network Discovery and File and Printer Sharing and the situation is next: File and Printer Sharing is turned on all layers (Private, Public and Domain) while Network Discovery is off for all layers too. I don't know if this
is normal thing but Network Discovery cannot be turned on in Windows Server (I'm able to select Turn on Network Discovery and apply the changes, but when I get back to this settings page, I again see that it's turned off, so I assume this can't be changed
at all).
I also tried with icacls in command prompt and everything seems to be ok there regarding permissions. Share permissions are set to Full control to Everyone and Security permissions are set to Full control only for Administrators and the user group I've created
for employees in my company. The confirmation for this is that on Windows 8 machines you can access this folder without any problem and without getting any message connected with access permissions with any user account within this user group. This share is
created through File and Storage Services service in Server Manager panel.
And then something came up on my mind. I went in Server Manager to check shared folder settings in File and Storage Services and under Settings page I saw that "Encrypt data access" has been enabled (I enabled this option because I thought
I will get more security with this option). I asked my self what would happen if I disable it, tried it and now everything works ok on Windows 7 machines too. Now I assume that Windows 7 doesn't have this feature implemented or there are some
settings which needs to be set on Windows 7 machines to make this encryption thing work with Windows Server. So basically, I will let this feature off for now until I find out more about it and how to implement it to work with all operating systems.
I want to thank you once more for your kind help! -

Have you tried accessing the share using smbclient? (smbclient //server/share)
I have been receiving the original dbus error for some time now.
I am using share level security on the server.
Using smbclient results in a segfault. Using nautilus also results in an error from libsmbclient which can be seen in one of the log files.
[mythtv@tvee ~]$ smbclient //sirschmoopy/shared
Enter mythtv's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.1]
Server not using user level security and no password supplied.
Segmentation fault
There is a samba bug which looks similar but it only affects people with ipv6 disabled. I have disabled and enabled ipv6 several times and the errors persist.
I think it may be related to this bug: https://bugzilla.samba.org/show_bug.cgi?id=7250

JNI: get Window-Handle of JFrame
Hello,
I'm calling a DLL method (written in VC), that needs a Window-handle (HWND) as parameter. How can I get the Handle of my JFrame to pass it into the DLL function?
All samples are designed for getting the HWND of a Canvas. But obviously it does not work with any kind of Frame.
Can somebody tell me ?
Thank you, Lars

You don't need to download the Windows support software, because in Snow Leopard, they are only available as a download for the Late 2010 MacBook Air.
Instead, you have to buy Mac OS X Snow Leopard. The Snow Leopard disc contains the Windows drivers for your Mac, so you have to install them after finishing the Windows installation -

Hi All,
I am facing below issue while access 10gr2 database from sqlplus.
I am having two oracle homes on one server one belongs to 11gr2 and another belongs to 10gr2.
I want to access a 10gr2 database through sqlplus utility.but instaed of connecting to 10gr2 it is connecting to 11gr2 after I enter a user name and passowrd.
I have set all the env variables such as oracle_home ,oracle_sid and path with respect to Oracle 10gr2.
Can you please let me kno what I need to do to connect to 10gr2 database and not 11gr2 database through sql plus.
Let me know if I need to give any more details on this.
Best Regards,
Dipti SHi Rocky,
I got the resolution.
I made a mistake by creating an oracle instance/service(e.g. fsdmo) when Oracle_home was pointing to 11gR2 Directory.so that service was refering to 11gr2 oracle home.
hence when I was setting oracle_sid(fsdmo) and trying to access database instance from 11g sqlplus utility ,it was directing to 11g and not 10g since oracle service was pointing to 11g.
So now after chnaging the oracle home directory to 11g,I am creating a service and its working fine.
thank you so much for responding.
hope I am clear with my reply.
Best Regards,
Dipti S
