• Is asking for control totals on a file an outdated means of verifying a file?

  - by CTKeane

  I'm in a new position where I need to process a flat files on a regular basis. The last time I did this was 5 or 6 years ago but as part of the file layout I received control totals. It gave me simplistic information on the file like the total number of records as well as sums of the important fields. This helped me during testing then also during production to verify the file arrived and has correct information. I have asked for similar data for this new project and have hit a wall of no. Is this no longer a standard practice? Is there a better way?

• which one consume less resources? opening text file or make an sql query,both a thousand times ?

  - by imin

  hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

• hosts file ignored, how to troubleshoot?

  - by Superbest

  The hosts file on Windows computers is used to bind certain name strings to specific IP addresses to override other name resolution methods. Often, one decides to change the hosts file, and discovers that the changes refuse to take effect, or that even old entries of the hosts file are ignored thereafter. A number of "gotcha" mistakes can cause this, and it can be frustrating to figure out which one. When faced with the problem of Windows ignoring a hosts file, what is a comprehensive troubleshoot protocol that may be followed? This question has duplicates on SO, such as hosts file seems to be ignored, HOSTS file being ignored, /etc/hosts file being ignored as well as numerous discussions elsewhere. However, these tend to deal with a specific case, and once whatever mistake the OP made is found out, the discussion is over. If you don't happen to have made the same error, such a discussion isn't very useful. So I thought it would be more helpful to have a general protocol for resolving all hosts-related issues that would cover all cases.

• Dreamweaver not loading due to workspace file problem

  - by Lynda

  I went to launch Dreamweaver CS 5.5 and this message popped up: XML parsing fatal error: Invalid document structure, line 1, file C:\Documents...(file path)...Workspace\My Workspace.xml It was followed by The following panel layout is missing or could not be read: C:...My Workspace.xml The application will not have a correct layout. Please load one from WindowsWorkspace After that, Dreamweaver acted as if it was going to load, but never did. When I tried to close the program, it crashed. I followed the file path and I saw two files: My Workspace.xml 0kb and My Workspace 5kb. The second one has an unknown file type. I deleted the first file and renamed the unknown file type to My Workspace.xml; everything worked fine after that point. Why did Dreamweaver do this? This has happened several times, but I have not changed anything that should affect that file type.

• How to uncompress a 9GB file in Windows FAT32

  - by Kashif

  I have a 2GB RAR file that contains a 9GB video file. I'm using a FAT32 file system. Now I want to unzip that file but after 4GB I get an error due to the FAT32 file size limit. Now I want to know that how I can extract that video? I know that one way is to convert my partition to NTFS but I don't want to follow that way. I've also tried 7-zip but that again gives error after 4GB. One other way is to split that file but I don't know how I can split a video file that is zipped. So any idea please? How can I get rid of this problem.

• Why does a zip file appear larger than the source file especially when it is text?

  - by PeanutsMonkey

  I have a text file that is 19 bytes in size and having compressed the file using zip and 7zip, it appears to be larger. I had a read of the question on Why is a 7zipped file larger than the raw file? as well as Why doesn't ZIP Compression compress anything? but considering the file is not already compressed I would have expected further compression. Attached is a screenshot. EDIT0 I took the example further by creating a file that contained random data as follows dd if=/dev/urandom of=sample.log bs=1G count=1 and attempted to compress the file using both zip and 7zip however there were no compression gains. Why is that?

• MPlayer refuses to generate mono wav file

  - by JCCyC

  I want to downsample an existing audio file to 8KHz mono. This command line downsamples it to stereo: mplayer -quiet -vo null -vc dummy -af volume=0,resample=8000:0:1 -ao pcm:waveheader:file="/tmp/blah1.wav" ~/from_my_cellphone.3ga It generates a file that the file utility identifies as stereo: $ file /tmp/blah1.wav /tmp/blah1.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 8000 Hz Now, if I read the documentation correctly, I should add pan=1:0.5:0.5 so I get a file that's half the size: mplayer -quiet -vo null -vc dummy -af volume=0,resample=8000:0:1:pan=1:0.5:0.5 -ao pcm:waveheader:file="/tmp/blah2.wav" ~/from_my_cellphone.3ga But it doesn't! blah2.wav is identical to blah1.wav! What am I doing wrong?

• How to Unblock Previously Unblocked CHM File

  - by OnesimusUnbound

  Wierd? Anyway, on Windows 7, I've downloaded a CHM file on the desktop and unblocked it by Property > Unblock. I moved the CHM file to a folder on the desktop to organize the files, and when I opened the file, the content of the CHM reader couldn't open the pages in the CHM file. I've open the file property, but the unblocked button is gone. Well, I can simply download the file, though I find the problem interesting and I need to know how to troubleshoot it. So, how can I unblock the said file? Update Clarified location. I was referring to a folder in the desktop, not in network drive.

• Unrecognized file format .mdb in Microsoft Access -- repair doesn't fix it

  - by user1282159

  So what I have is a file from a staff computer that I believe is an access file b/c its called .mdb, however it does not open! I even tried to follow the repair steps (create a new file and use the "compact and repair" tool. and all I keep getting is "unrecognized file format *.mdb" (replace the * with the filename). I am not even sure it is an access file. I have tried using Office 2007 and office 2010 but neither work. Is there a way to fix this that is not on the Microsoft website? Or to determine whether this is actually an access file and not some other file with the extension renamed? Any help would be appricated, thanks.

• How can I find the original un-changed configuration file to compare with the *.rpmnew file?

  While upgrading from CentOS 5.7 to 5.8 I've received the following warnings: warning: /etc/sysconfig/iptables-config created as /etc/sysconfig/iptables-config.rpmnew warning: /etc/ssh/sshd_config created as /etc/ssh/sshd_config.rpmnew warning: /etc/odbcinst.ini created as /etc/odbcinst.ini.rpmnew (To know the reason for such files, and what one can do with them read - Why do I have .rpmnew file after an update? ) I want to know what exactly has been change in the default config file by comparing the old default file (the original un-changed configuration file) with the new default file (*.rpmnew). Then, I can apply the changes to my modified file (aka diff merge). The problem is I don't know where can I find the original un-changed configuration file...

• word 2010 Macro to name and Save file when opened

  - by Phillip Clark

  I have a word document template and will be using a hyper link in Excel to access the word file. The issue I need to resolve is making sure once it is opened a message field box is "popped" up asking the user to create a new file name ... (in this case the current date) for each time the file is opened. In the message pop when finished entering in file name they click yes and then the save screen comes up with the path/file type (macro enabled document) and the file name they have already entered in the pop up.. All they should have to do from the save screen is click ok and it saves the file to a certain path/folder on the C drive of the computer. Once they finish typing in their notes they click a active x button to save and close and they are finished. If anyone can help with this it would be fantastic.
