If your fonts are changing when viewed on other computers - epecially those running windows - you need to look at using web-safe fonts...

Also make sure you clear your browser cache before viewing you published files.

So now that you have repeated the same thing three times that doesn't make things any clearer at all.
You are copying files from where to where?
How are you attempting to copy files, software or click and drag?
Any other detail would be helpful.

Problems with loading .bmp or .png files.

When I try to load a .bmp (or .png) file (with the example from the LabView-Homepage) I do not get the picture. There are only lines which (I guess when they are in the right order) will display the image correctly. Can you help me?
Thanks,
Armin Herzer
P.S.: I'm using LabView 6.0 for Linux

Hello,
yesterday I came across the following: If you save the PGM-Image as a BMP with the following command
convert 00.pbm 00.bmp
you ran into trouble with Labview (because the image is saved in a packed format). If you save the image with this command
convert +compress 00.pbm 00.bmp
Labview displays the image correctly (because packing is now disabled). I suppose, that Labview (at least the Linux version) cannot handle compressed BMP's correctly. You can verify the same with the Gimp. If you enable RLE packing, the image is distorted. If you disable it, everything is o.k.
By the way, I wasn't able to display a PNG Image (but I tried not all variants of saving it). JPG is not of interest, because the image
s that must be processed are not allowed to be compressed with information loss (o.k., I can use 0% compression mode, but then I can use BMP).
Can you verify this behavior with Windows too?
The PGM-Image is created by a C-Programm written by me.
This program acts as a driver for a Leutron LFS-AT framegrabber board and should be included in Labview as a CIN (if I find a way to display the images :-)
Thanks in advance,
Armin

How to make the result showing one time and make the result to csv file?

My script having problem of showing out all the AD computer name result from Active Directory once when running it and storing the result to csv file. I am a newbie in AD and powershell.
This is the code:
$strADPathFile = "D:\Powershell for AD\ADPathList.txt"
$strErrLogFile = "D:\powershell for AD\errorADComputer.log"
$arrADPath = Get-Content -Path $strADPathFile
foreach ($strADPath in $arrADPath)
try
$objSearch = New-Object DirectoryServices.DirectorySearcher
$objSearch.Filter = '(objectCategory=computer)'
$objSearch.SearchRoot = $strADPath
$objSearch.SearchScope = "Subtree"
$objSearch.PageSize = 1000
$objResults = $objSearch.Findall()
write-host "Retrieving AD computer information in the domain $strDomain"
write-host "Number of AD Computer Name result: "$objResults.Count
foreach($objResult in $objResults){
$objComputer = $objResult.GetDirectoryEntry()
write-host $objComputer.dNSHostName
try
# InsertSQLTable $objComputer
catch
write-host $error[0]
$strError = $objComputer.dNSHostName + " " + $dateNow + $error[0]
Add-Content $strErrLogFile $strError
catch
write-host $error[0]
Export-Csv D:\PowerShellforAD\test2.csv
This is the error that I had get is that it will get the result for 2nd time again.
By the way, what is InputObject about? I had research some of it and still did not quite get it. Can anyone explain? Thanks

Hi,
in the final line you call Export-Csv. which is a great command at exporting information. However, for it to work it needs a path to export to (D:\PowerShellforAD\test2.csv in your case) and Information (InputObject) to export.
You do not give that command any Information, so it throws an error.
Cheers,
Fred

Hi - I'd recommend running the print diagnostic utility for starters. It should help isolate the problem and hopefully resolve it automatically. At the very least, it is a good starting point.
Hope that helps.

Illustrator CC2014 won't reopen file just recently edited and closed. "Illustrator cannot open file" message.

Windows 7 Home Premium, Dell XPS desktop. First problems with AI in a LONG time. Used to be able to go to the control panel for programs and "repair" the installation, now can only un-install.
This file is originally from a previous version of AI, opened it in CC2014 and edited, nothing extensive, just text updates, and after closing, it won't open again. And the program crashed. After a re-start of the computer, I could open a different file, but not the "problem" file. After re-doing the edits on another (even earlier) copy of the source file, the same thing happened. I can place the file in InDesign, and export to pdf, which views fine. I plan to try to edit the InD pdf in Illustrator, to see what happens.
Otherwise the computer seems to be fine, all other apps seem stable. So far.

The file size is the same as the previous version. I placed the AI file into InD, made a pdf, and can open and edit that pdf in Illustrator. If I could get the "bad" file to open, I would save as to a new file, see if that would help, but since it won't open.... Just weird. I should have what I need now, so I don't plan to spend any more time on it. Thanks for thinking about it. I just hope I don't end up eventually having to uninstall/re-download and re-install Illustrator!
The only image is embedded, no link. I don't have any non-standard plug-ins. I will keep in mind about the preferences, but why only this 1 file having a problem with them? I did install some fonts for another job while also working on this; I will keep that in mind, too.
Thanks again.

Pshop CC -- saving JPG & PNG file size bloat

Saving JPGs & PNGs from Photoshop CC is creating what I can only describe as a obscene file bloat. Just recently, what should have been a 7k jpg saved as a 1.1 mb jpg file. PNGs which should average roughly 100-150k are coming out at 1.3mb. If I use the "Save for Web", sometimes it gives me the proper sized images.
I have noticed this on 2 computers --- one a mac & one windows with completely different file sets. So it is not an issue of my OS, the original files or anything specific to one particular common item.
FYI -- Doing the same thing with pshop cs6, I get the proper file sizes.
I have included a sample image here. This image is a straight out "save" from pshop CC -- it is 1.1mb. However, when I saved the same image as a JPG in pshop cs6, it was 7k.
Is anyone else experiencing this issue?

Haven't had a PNG or JPG go wacky here in that way so far...
I think the issue is revealed by looking in File - File Info in the Raw Data section. I don't know why, but there are a huge number of <rdf:li> XML elements showing up there with hex values in them. I don't know what that means, exactly, but I believe the accumulation of that metadata explains the size increase.
Do any of the terms you see in the raw metadata mean anything to you? Do you have 3rd party plug-ins that could be responsible for this?

How to call a SP with dynamic columns and output results into a .csv file via SSIS

hi Folks, I have a challenging question here. I've created a SP called dbo.ResultsWithDynamicColumns and take one parameter of CONVERT(DATE,GETDATE()), the uniqueness of this SP is that the result does not have fixed columns as it's based on sales from previous
days. For example, Previous day, customers have purchased 20 products but today , 30 products have been purchased.
Right now, on SSMS, I am able to execute this SP when supplying a parameter. What I want to achieve here is to automate this process and send the result as a .csv file and SFTP to a server.
SFTP part is kinda easy as I can call WinSCP with proper script to handle it. How to export the result of a dynamic SP to a .CSV file?
I've tried
EXEC xp_cmdshell ' BCP " EXEC xxxx.[dbo].[ResultsWithDynamicColumns ] @dateFrom = ''2014-01-21''" queryout "c:\path\xxxx.dat" -T -c'
SSMS gives the following error as Error = [Microsoft][SQL Server Native Client 10.0]BCP host-files must contain at least one column
any ideas?
thanks

Hey Jakub, thanks and I did see the #temp table issue in our 2008R2. I finally figured it out in a different way... I manage to modify this dynamic SP to output results into
a physical table. This table will be dropped and recreated everytime when SP gets executed... After that, I used a SSIS pkg to output this table
to a file destination which is .csv.
The downside is that if this table structure ever gets changed, this SSIS pkg will fail or not fully reflecting the whole table. However, this won't happen often
and I can live with that at this moment.
Thanks

How to get the value from a JavaScript and send the same to Java file?

Hi.
How to get the value from a JavaScript (this JS is called when an action invoked) and send the value from the JS to a Java file?
Thanks and regards,
Leslie V

Yes, I am trying with web application.
In the below code, a variable 'message' carries the needed info. I would like to send this 'message' variable with the 'request'.
How to send this 'message' with and to the 'request'?
Thanks for the help :-)
The actual JS code is:
function productdeselection()
var i=0;
var j=0;
var deselectedproduct = new Array(5);
var message = "Are you sure to delete Product ";
mvi=document.forms[0].MVI;
mei=document.forms[0].MEI;
lpi=document.forms[0].LPI;
if(null != mvi)

How can I get Indesign CS6 to open JPG/PNG files?

I recently purchased Indesign CS6. When I went to import a PNG, it failed to recognize it. I then tried a JPG to no avail. The exact error message reads as follows:
"Cannot open the file "photo.png". Adobe Indesign May not support the file format, a plug-in that supports the file format may be missing, or the file may be in another application."
How could the plug-ins be missing? Wouldn't these be installed with Indesign? Any advice as to how to proceed?.
Thanks in advance.

You need to use the file>place command.
This is very, very basic and I'd respectfully suggest that you take a step back and learn a bit about the program. This link will get you a free one week trial of Lynda.com where you'll find some fabulous video training: http://bit.ly/RS0GXs

How do I get a more modern look and feel for a compiled help file

I gather from reading various posts that there is no easy way
to generate a .chm file with a more modern look and feel (am I
right about this?). Are there no plug-ins available from Adobe that
will enable us to generate a help file that looks more modern?
I hesitate to move to flash help or something like that
because, of course, then the developers would have to hookup the
hundreds of dialog boxes we have in our product to the new files. I
also think that having one file is way easier to manage in terms of
getting updated help to the customers. What are online Help
developers generally delivering for apps where users are not
connected to the Internet except perhaps periodically while using
the software? I'm a writer (not a developer) so need soemthing that
is easy to implement :-)
Thanks for your help. It is much appreciated.

To add to the advice already offered, you can apply a skin to
a CHM file which allows you to customise it. However as with most
things there are issues with this approach. You can read about this
by downloading Rick Stone's excellent
tips
'n tricks file. Just look in the index under "skins". Something
else you may want to look at is the beta of Adobe's
AIR.
