• I can't delete a file - even when using unlocker

  - by chipperyman573

  So I have a 64 bit windows 7 ultimate computer. On my desktop, I have a .iso file that should NOT be used by anything. However, when I use lockhunter (unlocker doesn't work for me), it says it can't unlock or delete it. When I check what it's being used by, it says by the system. Here's a picture when I click delete: Here's a picture of when I click unlock it: When I click Other Close locking process: I've had this file on my computer for a LONG time now and haven't been able to delete it. I've also tried eraser erase on startup, but that doesn't work, either. How can I remove this file?

• Cannot Delete "Account Unknown" account in Windows XP SP3

  - by naspinski

  If I Right click on My Computer, Select Properties, then click on Advanced-User Profiles-Settings, I get a list of user accounts on my machine and I see a few that are "Account Unknown" in there with large profiles and I want my space back. I am assuming this is because these users are long gone and AD no longer recognizes their SIDs. The problem is that the Delete button is grayed out, but only for the accounts, the ones that are recognized, I can delete jsut fine. These accounts do not show up in Computer Management at all, and I am an administrator on my machine - any ideas on how to delete them?

• Weird files in User folder

  - by Vervious

  In my user folder (C:/Users/myAccount/) theres a set of interesting hidden files that I've never seen before (right now it's a fresh install of Windows 7 Ultimate). These are: NTUSER.DAT, ntuser.dat.LOG1, ntuser.dat.LOG2, and NTUSER.DAT(whole chain of numbers and letters).TM.bif, NTUSER.DAT(whole chain of numbers and letters).TMContaineretcetc.regtrans-ms, and another similar one. When I try to delete them, it says the system is using them. I've never seen these files before. Are they ok to delete? Or should I leave them in my home folder? I always keep "Show hidden files" as well as "Show System files" checked, since I prefer being able to see all the files on my computer. If I shouldn't delete them, is there at least a way to tidy them up a bit? Thanks.

• Delete files on external hard drive affect SSD?

  - by haar

  I've got a SSD as my primary hard drive. I have an external HDD hard drive which I use to store downloaded files. At the moment I have to delete 80 GB of that external hard drive. I realized that if I delete it normally, it would probably go to the recycle bin of my SSD. I am wondering how I can delete the files on my HDD without affecting the SSD or putting any files on it. Do you know how to do this? Best, haar

• Deleting file in Samba doesn't delete file?

  - by Jeff Welling

  Why, when I delete some files in Samba, does it not delete them but instead merely change their filename from filename.txt to ._filename.txt? This is not the behaviour one would expect when "deleting" a file, so I'm wondering if there's an option I forgot to set somewhere in the samba config. It does this to some files but not to others, I have not yet spotted a pattern to its choosiness. There is a Ubuntu 12.04 machine and a Mac OS X machine which have write (and thus delete) capability, no Windows machines have write permission.

• Unable to remove a file which have a name like a command argument

  - by Justin

  By inadvertance, I've created a file called -r into my home directory. Please don't ask me how and why, I don't recall. But the fact is that now I cannot get rid of it : rm -rf rm: missing operand Try 'rm --help' for more information. Other try : rm /-/r rm: cannot remove ‘/-/r’: No such file or directory Another one : rm \-r rm: missing operand Try 'rm --help' for more information. Is there a way to remove this file without deleting the whole directory ? Thanks.

• Unable to delete files in Temporary Internet Files folder

  - by Johnny

  I'm on Win7. I have a large number of of large .bin files, totaling 183GB, in my Temporary Internet Files folder. They all seem to come from video sharing sites like youtube. The files are invisible in Explorer even after allowing viewing of hidden files. The only way I can see them is by issuing "dir /fs" on the command line. Now when I try to delete them from the command line nothing happens. Trying to delete the whole folder from Explorer results in access denied because another process is using a file in the folder (IE is not running while I'm doing this). Trying to clear the folder using IE is also unsuccessful. How do I delete these files? How did they end up being there without being deleted by IE?

• Using a PowerShell Script to delete old files for SQL Server

  Many clients are using custom stored procedures or third party tools to backup databases in production environments instead of using database maintenance plans. One of the things that you need to do is to maintain the number of backup files that exist on disk, so you don't run out of disk space. There are several techniques for deleting old files, but in this tip I show how this can be done using PowerShell.

• Delete all traces of windows from Ubuntu

  - by TheOm3ga

  I used to have a dual boot in one of my hard disk drives - Ubuntu and Windows 7. Then, I added a SSD which is now my main hard disk drive, and I'm using it for Windows 7 completely, keeping Ubuntu in the old HD. I restored the Grub so everything works ok, except for one thing. Everytime I update the grub, it detects two windows: Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 Obviously, I don't want it to detect the Windows on sdb1. Because I no longer use it (I manually deleted the files). What can I do about that without wiping out completely the partition?

• Excel macro to delete empty rows isn't stopping

  - by RocketGoal

  How do I make it stop after a certain amount of rows? I've taken a VBA course and my teacher explained how to delete empty rows. I'm now trying to put this in place but my macro isn't stopping. I thought I had limited it to 200 rows. I'm missing something important. Any pointers much appreciated. Sub RemoveRows() ' Remove rows from last blank cell Dim LastRow As Long Dim ISEmpty As Long 'Count how many records in the list. This is done so that the Do loop has a finish point. LastRow = Range("A200").End(xlUp).Row 'Start at the top of the list Range("A1").Select 'Loop until the end of the list Do While ActiveCell.Row < LastRow 'Assign number of non empty cells in the row ISEmpty = Application.CountA(ActiveCell.EntireRow) 'If ISEmpty = 0 then delete the row, if not move down a cell into the next row If ISEmpty = 0 Then ActiveCell.EntireRow.Delete Else ActiveCell.Offset(1, 0).Select End If Loop End Sub

  I am writing a simple program to understand the new and delete operator overloading. How is the size parameter passed into the new operator? For reference, here is my code: #include<iostream> #include<stdlib.h> #include<malloc.h> using namespace std; class loc{ private: int longitude,latitude; public: loc(){ longitude = latitude = 0; } loc(int lg,int lt){ longitude -= lg; latitude -= lt; } void show(){ cout << "longitude" << endl; cout << "latitude" << endl; } void* operator new(size_t size); void operator delete(void* p); void* operator new[](size_t size); void operator delete[](void* p); }; void* loc :: operator new(size_t size){ void* p; cout << "In overloaded new" << endl; p = malloc(size); cout << "size :" << size << endl; if(!p){ bad_alloc ba; throw ba; } return p; } void loc :: operator delete(void* p){ cout << "In delete operator" << endl; free(p); } void* loc :: operator new[](size_t size){ void* p; cout << "In overloaded new[]" << endl; p = malloc(size); cout << "size :" << size << endl; if(!p){ bad_alloc ba; throw ba; } return p; } void loc :: operator delete[](void* p){ cout << "In delete operator - array" << endl; free(p); } int main(){ loc *p1,*p2; int i; cout << "sizeof(loc)" << sizeof(loc) << endl; try{ p1 = new loc(10,20); } catch (bad_alloc ba){ cout << "Allocation error for p1" << endl; return 1; } try{ p2 = new loc[10]; } catch(bad_alloc ba){ cout << "Allocation error for p2" << endl; return 1; } p1->show(); for(i = 0;i < 10;i++){ p2[i].show(); } delete p1; delete[] p2; return 0; }

Any easy way to do this without iterating through the objects in the vhost delete?

• Webbrowser control and cookies

  - by Mike

  Hello! I have a webbrowser control in my program and what I want to do is to delete all the cookies stored in my computer. The problem is that for example I'm in some site, and then I decide I want to delete all the cookies, so I do it by the command "Kill()" but the problem is that the cookies remain and this site still can recognize me, and to complete the kill command I need to close my program and enter it again. The webbrowser control uses Internet Explorer, and I think when you enter IE it somehow loads all the cookies into it so if you delete your cookies, they remain there. So I'm wondering how can I delete my cookies, completely delete them without the need to close my program and enter it once again. Any help will be appreciated!

• MySQL script to delete data in chunks until everything lower then id has been deleted

  - by Chriswede

  I need an MySQL Skript which does the following: delete chunks of the database until it has deleted all link_id's greater then 10000 exmaple: x = 10000 DELETE FROM pligg_links WHERE link_id > x and link_id < x+10000 x = x + 10000 ... So it would delete DELETE FROM pligg_links WHERE link_id > 10000 and link_id < 20000 then DELETE FROM pligg_links WHERE link_id > 20000 and link_id < 30000 until all id's less then 10000 have been removed I need this because the database is very very big (more then a gig) thank in advance

• Confirm delete of record, from method

  - by Melt

  Hi all, How can I pop up a message box to confirm a delete, from inside a method? Normally i would just use the following line in my button: OnClientClick="return confirm('Are you sure you want to delete this comment?');" However this delete method can also be called by a querystring, so I need the confirm message box functionality in the method, please? // delete comment method private void DeleteComment() { int commentid = Int32.Parse(Request.QueryString["c"]); // call our delete method DB.DeleteComment(commentid); } I can't click the button through code, because it doesn't fire the OnClientClick event btnDelete_Click(null, null); Regards Melt

• Problem with cascade delete using Entity Framework and System.Data.SQLite

  - by jamone

  I have a SQLite DB that is set up so when I delete a Person the delete is cascaded. This works fine when I manually delete a Person (all records that reference the PersonID are deleted). But when I use Entity Framework to delete the Person I get an error: System.InvalidOperationException: The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted. I don't understand why this is occurring. My trigger is set to clean up all related objects before deleting the object it was told to delete. When I go into the model editor and check the properties of the relationship it shows no action for the OnDelete property. Why isn't this set correctly by pulling it from the DB? If I change this value to Cascade everything works properly, but I would rather not rely on this manual change because what if I refresh my model from the DB and it looses that. Here's the relivent SQL for my tables. CREATE TABLE [SomeTable] ( [SomeTableID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, [PersonID] INTEGER NOT NULL REFERENCES [Person](PersonID) ON DELETE CASCADE ) CREATE TABLE [Person] ( [PersonID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT )

• Javascript Confirm Delete in One PHP File (on href)

  - by gamerzfuse

  <p><span class="linky"><a href="deletephone.php?id=' . $row['id'] . '">Delete Phone</a></span></p><br /> I have the above code that I am using to link to a delete script. I want to somehow incorporate Javascript with a simple onclick confirmation. This way if they choose OK, I can run the code to delete the item from the database, but if they choose Cancel then I can cancel the operation and do nothing. I have tried a whole variety of functions with changing the window.location to the delete file, and trying to cancel the href= if they choose Cancel, but it always goes to the link regardless of what the user clicks. I would like to be able to keep the delete functions inside the same PHP file if possible, but this is not necessary at all. Thanks in advance! ASIDE: If there is a simple PHP way to check IF the alert was confirmed or denied, that could work also. Any way to check what the user chooses and then run my simple delete PHP command.

• Batch File to Delete Folders

  - by Homebrew

  I found some code to delete folders, in this case deleting all but 'n' # of folders. I created 10 test folders, plus 1 that was already there. I want to delete all but 4. The code works, it leaves 4 of my test folders, except that it also leaves the other folder. Is there some attribute of the other folder that's getting checked in the batch file that's stopping it from getting deleted ? It was created through a job a couple of weeks ago. Here's the code I stole (but don't really understand the details): rem DOS - Delete Folders if # folders > n @Echo Off :: User Variables :: Set this to the number of folders you want to keep Set _NumtoKeep=4 :: Set this to the folder that contains the folders to check and delete Set _Path=C:\MyFolder_Temp\FolderTest If Exist "%temp%\tf}1{" Del "%temp%\tf}1{" PushD %_Path% Set _s=%_NumtoKeep% If %_NumtoKeep%==1 set _s=single For /F "tokens=* skip=%_NumtoKeep%" %%I In ('dir "%_Path%" /AD /B /O-D /TW') Do ( If Exist "%temp%\tf}1{" ( Echo %%I:%%~fI >>"%temp%\tf}1{" ) Else ( Echo.>"%temp%\tf}1{" Echo Do you wish to delete the following folders?>>"%temp%\tf}1{" Echo Date Name>>"%temp%\tf}1{" Echo %%I:%%~fI >>"%temp%\tf}1{" )) PopD If Not Exist "%temp%\tf}1{" Echo No Folders Found to delete & Goto _Done Type "%temp%\tf}1{" | More Set _rdflag= /q Goto _Removeold Set _rdflag= :_Removeold For /F "tokens=1* skip=3 Delims=:" %%I In ('type "%temp%\tf}1{"') Do ( If "%_rdflag%"=="" Echo Deleting rd /s%_rdflag% "%%J") :_Done If Exist "%temp%\tf}1{" Del "%temp%\tf}1{"
