Will Windows Barf on Constant Video Driver Overwrite?

- by Maarx

So, I've got a Win7 64-bit gaming PC with GTX 260's. Recently, StarCraft 2 had an issue with flickering, which NVidia fixed with a new set of drivers. However, these new drivers induce unplayable graphical errors with Neverwinter Nights 2, something me and my friends still play from time to time. I am seeking advice on the "best" way to rectify this situation, to be able to switch between two driver releases, without compromising the stability of my system (if Windows stability isn't an oxymoron). I'm wondering if Windows 7 is structured in such a way that I can constantly reinstall these two sets of drivers back and forth overtop each other, possibly six or eight times a day, without very quickly driving myself to reformat to maintain that "just like new" performance. I'm loathe to have to reformat the drive and maintain two copies of the operating system, but I'll do it if I have to.

problems with extended classes and overwrite with methods

- by Marco

I have a .net website written in C# and will make functionalities that other developers can use. So i will make some default implementation and a developer can overwrite some methods Example: i have a class ShoppingCart and a class Product the class product haves a method getProductPrice the shoppingcart will call the method getProductPrice for calculating the total price of cart The Shoppingcart and Product are in the same project and i will give the developers the .dll so they can't change the source code so we can update the assembly later So they need to make a other project and extend the product class and overwrite the method getProductPrice so they can implement there own logic The problem is that the shoppingcart will not call the extended method but the original If we make already a extended project for the developers and the shoppingcart will call the extended method then we have a circular reference because the extended product needs a reference to product and the shopping cart to the extended product partial classes also don't works because we only can use partials within the same assembly anyone a suggestion ? thanks in advance

How do I overwrite a file currently being read by Python

- by Brian

Hi guys, I am not too sure the best way to word this, but what I want to do, is read a pdf file, make various modifications, and save the modified pdf over the original file. As of now, I am able to save the modified pdf to a separate file, but I am looking to replace the original, not create a new file. Here is my current code: from pyPdf import PdfFileWriter, PdfFileReader output = PdfFileWriter() input = PdfFileReader(file('input.pdf', 'rb')) blank = PdfFileReader(file('C:\\BLANK.pdf', 'rb')) # Copy the input pdf to the output. for page in range(int(input.getNumPages())): output.addPage(input.getPage(page)) # Add a blank page if needed. if (input.getNumPages() % 2 != 0): output.addPage(blank.getPage(0)) # Write the output to pdf. outputStream = file('input.pdf', 'wb') output.write(outputStream) outputStream.close() If i change the outputStream to a different file name, it works fine, I just cant save over the input file because it is still being used. I have tried to .close() the stream, but it was giving me errors as well. I have a feeling this has a fairly simple solution, I just haven't had any luck finding it. Thanks!

is there a way to prespecify to overwrite files with same name?

- by Celeritas

Connections to network drives are ridiculously slow (e.g. 15kb/sec on really good days) and when I'm copying files I leave my desk. My problem is when there is a file with the same name to be overwritten, is there a way to specify in advanced to overwrite files? I know it has the option "do same for next x conflicts" but that doesn't popup until (in some cases) a long time after the files start copying. See my dilemma? Example: copying 500 files, estimated time 2 hours, I leave, after 10 minutes message comes up about file with same name and asks if it should overwrite (in this time copying stalls), I come back 30 minutes latter to find only the files in the 10 minutes copied. Out of curiosity how could the network speed be so bad? I asked the boss and he said because it gets routed around a lot and is just bad :(

Des chercheurs découvrent le premier malware à pratiquer l'overwrite, caché sous la forme d'un Adobe

Des chercheurs découvrent le premier malware à pratiquer l'overwrite, caché sous la forme d'un Adobe Updater Un code malicieux vient d'être repéré pour la première fois par des spécialistes en sécurité informatique. En effet, des chercheurs viennent de découvrir un malware qui se substitue aux mises à jour de certaines applications. Habituellement, ce type de programmes ne pratique pas l'overwrite. Seuls les ordinateurs tournant sous Windows sont touchés. Le malware se cache sous la forme d'un updater pour les produits Adobe ou Java. Une variante imite Adobe Reader v.9 et overwrite AdobeUpdater.exe, lequel a pour mission de se connecter régulièrement auprès des serveurs d'Adobe pour vérifier si une nouvelle version ...

Prevent APT from overwriting JCE jars

- by Doc

My server runs a Java application that requires I replace a few java library files with ones I downloaded on my own. This has to do with JCE security extensions and isn't really relevant to my question. I've found that these library files tend to get overwritten by apt when it later updates my java package. Is there a apt-friendly way of masking these specific files so apt won't touch them? Potential Solutions I'm considering just removing the write flag from the files, though I'm expecting this will cause apt to spew its guts everywhere when it later tries to overwrite them? Perhaps there's a java custom library directory I don't know of, where I can park my files and they'll be loaded instead of the package's defaults? The last-resort option I'm considering is writing a cron job to periodically replace the files with my versions. I hate this option.

550 “Overwrite permission denied” when editing a file via FTP

DreamHost recently moved my accounts to a new shared box, and now I can't edit files via UltraEdit's built in FTP client, which messes up my work flow! What did they do that this is not working now?

Property overwrite behaviour

- by jeremyj

I thought it worth sharing about property overwrite behaviour because i found it confusing at first in the hope of preventing some learning pain for the uninitiated with MSBuild :-)The confusion for me came because of the redundancy of using a Condition statement in a _project_ level property to test that a property has not been previously set. What i mean is that the following two statements are always identical in behaviour, regardless if the property has been supplied on the command line - <PropertyGroup> <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA> </PropertyGroup>has the same behaviour regardless of command line override as - <PropertyGroup> <PropA>PropA set at project level</PropA> </PropertyGroup> i.e. the two above property declarations have the same result whether the property is overridden on the command line or not.To prove this experiment with the following .proj file -<?xml version="1.0" encoding="utf-8"?><Project ToolsVersion="4.0" > <PropertyGroup> <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA> </PropertyGroup> <Target Name="Target1"> <Message Text="PropA: $(PropA)"/> </Target> <Target Name="Target2"> <PropertyGroup> <PropA>PropA set in Target2</PropA> </PropertyGroup> <Message Text="PropA: $(PropA)"/> </Target> <Target Name="Target3"> <PropertyGroup> <PropA Condition=" '$(PropA)' == '' ">PropA set in Target3</PropA> </PropertyGroup> <Message Text="PropA: $(PropA)"/> </Target> <Target Name="Target4"> <PropertyGroup> <PropA Condition=" '$(PropA)' != '' ">PropA set in Target4</PropA> </PropertyGroup> <Message Text="PropA: $(PropA)"/> </Target></Project>Try invoking it using both of the following invocations and observe its output -1)>msbuild blog.proj /t:Target1;Target2;Target3;Target42)>msbuild blog.proj /t:Target1;Target2;Target3;Target4 "/p:PropA=PropA set on command line"Then try those two invocations with the following three variations of specifying PropA at the project level -1) <PropertyGroup> <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA> </PropertyGroup> 2) <PropertyGroup> <PropA>PropA set at project level</PropA> </PropertyGroup>3) <PropertyGroup> <PropA Condition=" '$(PropA)' != '' ">PropA set at project level</PropA> </PropertyGroup>

How to avoid clobbering files when creating a tar archive

- by Andrew Grimm

This question notes that it is possible to overwrite files when creating a tar archive, and I'm trying to see how to avoid that situation. Normally, I'd use file roller, but the version installed is playing up a bit (using 1.1 Gb of memory), and I'm not the system administrator. I looked at --confirmation and --interactive, but that only asks me if I want to add file x to the archive, not whether I want to overwrite an existing file. For example, tar --interactive -czvf innocent_text_file.txt foo* Will ask me about each file, but is perfectly happy to overwrite innocent_text_file.txt Is there any switch that acts like -i for cp? Note I am asking about creating an archive, not extracting an archive. Clarification What I'm worried about is accidentally doing something like this tar -czvf * #Don't do this! which would overwrite the first file listed in the glob. To avoid it, I want tar to complain if the first file mentioned already exists, like cp -i * #Don't do this! would check if it would cause you to overwrite an existing file.

How to get pngcrush to overwrite original files?

- by DisgruntledGoat

I've read through man pngcrush and it seems that there is no way to crush a PNG file and save it over the original. I want to compress several folders worth of PNGs so it would be useful to do it all with one command! Currently I am doing pngcrush -q -d . *.png then manually cut-pasting the files from the tmp directory to the original folder. So I guess using mv might be the best way to go? Any better ideas?

Overwrite previous output in Bash instead of appending it

- by NES

For a bash timer i use this code: #!/bin/bash sek=60 echo "60 Seconds Wait!" echo -n "One Moment please " while [ $sek -ge 1 ] do echo -n "$sek " sleep 1 sek=$[$sek-1] done echo echo "ready!" That gives me something like that One Moment please: 60 59 58 57 56 55 ... Is there a possibility to replace the last value of second by the most recent so that the output doesn't generate a large trail but the seconds countdown like a real time at one position? (Hope you understand what i mean :))

How to overwrite Ubuntu with Windows 7?

- by Will Cowled

So I have a Windows DVD and it works. But when it gets to the part when it says "Upgrade" or "Custom" I click on custom and at the bottom it says cannot install over it because Windows 7 can only be installed on an NTFS drive? I know that Ubuntu formatted my partitions into one big on that's an ext4. What can I do? I know that I can maybe create a 30-50 GB partition that's an ntfs then when I go into windows I can format the Ubuntu one and combine them but I don't know how to make a partition much less make a big partition in the "GParted" program? So any ideas would be very helpful. I know how to do anything with a hard drive using the default program that comes with Windows 7 but I feel like a mouse in a maze when I open GParted.

Linux: Can't overwrite files on samba store

- by jonescb

I'm using CentOS 5.5 with smbclient 3.0.33-3.28-el5 (latest version in repo), and I can't overwrite files in my Samba store. I am not the admin for the Samba server, so there isn't anything I can do server side. But I do have write permission to the server. I know the server runs Windows XP or Server 2003; I don't know. I can delete the file, and then copy the new version over, but I can't overwrite it. Using the cp command I'll get this error: [jonescb@localhost ~]$ cp foo.txt /mnt/si_storage/foo.txt cp: cannot create regular file `/mnt/si_storage/foo.txt': No such file or directory` And if I edit a file on the server using vim, I can save it once, but if I save it again I get this: "/mnt/si_storage/foo.txt" E212: Can't open file for writing This is my /etc/fstab entry for the samba server: //192.168.1.2/SI_STORAGE /mnt/si_storage cifs username=myuser,password=mypass 0 0 Edit: I can overwrite files just fine on my XP machine. The CentOS box is the only one having problems.

SFTP - Unable to Overwrite File - "EOF received from remote side"

- by NateReid

I am working with a customer to troubleshoot an error they have when trying to overwrite/"PUT" a file to our SFTP site. When the root directory is empty and they try to upload the file there is no problem but when they try to overwrite an existing file this is when the error occurs. The error they receive when trying a put command in Java Caps is: The error is: Batch SFTP eWay error when doing data transfer operation in [PUT()], message=[EOF received from remote side [Unknown cause]].|#] When they use WinSCP or FileZilla to put the file it overwrites fine with no errors. We have tried: Multiple different files Checking their SFTP user permissions Gave full access permissions to "everyone" to the user's root directory in Windows Recreating their user account Ensured no other processes are using/locking the files that are being overwriten We are using Cerberus Professional FTP server software. Any ideas of what else we could try?

How to allow wget to overwrite files

- by Gnanam

Using wget command, how do I allow/instruct to overwrite my local file everytime, irrespective of how many times I invoke. Let's say, I want to download a file from the location: http://server/folder/file1.html Here, whenever I say wget http://server/folder/file1.html, I want this file1.html to be overwritten in my local system irrespective of the time it is changed, already downloaded, etc. My intention/use case here is that when I call wget, I'm very sure that I want to replace/overwrite the existing file. I've tried out the following options, but each option is intended/meant for some other purpose. -nc = --no-clobber -N = Turn on time-stamping -r = Turn on recursive retrieving

mv directory to overwrite another

- by gbjbaanb

I may be going bonkers here, but I'm trying to move a directory to a new location, overwriting the contents (on Linux, using bash). Everytime I try it, it responds with "mv: cannot move `./src' to a subdirectory of itself" eg. I have: /src /new/dir/src /$ mv src/ new/dir/ If I delete the destination dir, then it works. I know I can move the contents of the source dir to overwrite the destination, but I'd like to use the same command to overwrite the destination if it already exists, or move the source if it doesn't.

Why is scp not overwriting my destination file?

- by Noli

I'm trying to back up a file via the command scp /tmp/backup.tar.gz hostname:/home/user/backup.tar.gz When I run it, the scp progress bar shows up and it looks like its transferring the file, however when I log into the destination server to check the file, the timestamp and filesize haven't changed from the older version, so it looks like scp didn't overwrite the old file at all. It only sees to work when I manually delete the file from the destination server. I'm running ubuntu, and this is happening on two servers: one cygwin ssh, and one fedora core 3. Anyone have any idea why this is happening? I thought scp would ONLY overwrite existing files.. Thanks

Overwrite text in Windows Notepad

- by Mark Miller

I would like to be able to overwrite text in Windows Notepad. I am using Windows 7 Professional. Ideally I would like to be able to position the cursor next to a string of text and erase that text by pressing the spacebar until the cursor has passed over every character in the string without adding additional spaces to the document. Is that possible? I have tried pressing the 'Insert' key, but that does not help. Nor does using 'Num Lock' and pressing the 'Ins' or '0' key. Unfortunately, I have not been able to find a solution elsewhere on the internet. I do not think I am using notepad++. The application is listed as 'notepad.exe' under 'Properties'. Thank you for any suggestions.

Does ssh-copy-id overwrite previous keys?

- by decker

I haven't yet found any definitive answer on this using google. It seems like the answer is no, but I need to know for sure before I go ahead and do it. Does ssh-copy-id append the key to authorized_keys or does it overwrite the previous keys? Thanks. Addendum: So the answer is right there in the man page. Go figure. I guess the question can at least help fellow Google-jockeys like me who get a little too used to googling and finding tutorials (that often explain things in layman's terms for us poor folks who have only used Windows our whole lives).

Python XLWT attempt to overwrite cell workaround

Hi, Using the python module xlwt, writing to the same cell twice throws an error: Message File Name Line Position Traceback <module> S:\******** write C:\Python26\lib\site-packages\xlwt\Worksheet.py 1003 write C:\Python26\lib\site-packages\xlwt\Row.py 231 insert_cell C:\Python26\lib\site-packages\xlwt\Row.py 150 Exception: Attempt to overwrite cell: sheetname=u'Sheet 1' rowx=1 colx=12 with the code snippet def insert_cell(self, col_index, cell_obj): if col_index in self.__cells: if not self.__parent._cell_overwrite_ok: msg = "Attempt to overwrite cell: sheetname=%r rowx=%d colx=%d" \ % (self.__parent.name, self.__idx, col_index) raise Exception(msg) #row 150 prev_cell_obj = self.__cells[col_index] sst_idx = getattr(prev_cell_obj, 'sst_idx', None) if sst_idx is not None: self.__parent_wb.del_str(sst_idx) self.__cells[col_index] = cell_obj Looks like the code 'raise'es an exception which halts the entire process. Is removing the 'raise' term enough to allow for overwriting cells? I appreciate xlwt's warning, but i thought the pythonic way is to assume "we know what we're doing". I don't want to break anything else in touching the module.

Delphi overwrite existing file on save dialog

- by AfterImage

Hello everyone, I am using the TSaveDialog component to save a file from a button click. However, I am having trouble with saving on an existing file name. Generally, when you want to save over an existing file in Windows, a message box pops up asking you if you really want to overwrite the file. This is not the case with the TSaveDialog component and it will go ahead and write over the file without asking. I was hoping there was a TSaveDialog function or event that I could use but I have not seen anything that looks like it handles this. So it could be that I simplely haven't found the correct method to use. If there is an event, I could use if FileExists(saveDialog.FileName) then //and so forth but the events TSaveDialog has are OnCanClose, OnClose, OnFolderChange, OnIncludeItem, OnSelectionChange, OnShow, OnTypeChange... My question is, how do I pop up a message box to ask the user if they want to overwrite the existing file using the TSaveDialog component. Thanks.
