  • Java RegExp ViewState

    - by CDSO1
    I am porting some functionality from a C++ application to java. This involves reading non-modifiable data files that contain regular expressions. A lot of the data files contain regular expressions that look similar to the following: (?<=id="VIEWSTATE".*?value=").*?(?=") These regular expressions produce the following error: "Look-behind group does not have an obvious maximum length near index XX" In C++ the engine being used supported these expressions. Is there another form of regexp that can produce the same result that can be generated using expressions like my example as input?

  • SQL Server: Are temp tables or unions better?

    - by Jonathan Allen
    Generally speaking, for combining a lot of data is it better to use a temp table/temp variable as a staging area or should I just stick to "UNION ALL"? Assumptions: No further processing is needed, the results are sent directly to the client. The client waits for the complete recordset, so streaming results isn't necessary.

  • About fork system call and global variables

    - by lurks
    I have this program in C++ that forks two new processes: #include <pthread.h> #include <iostream> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> #include <cstdlib> using namespace std; int shared; void func(){ extern int shared; for (int i=0; i<10;i++) shared++; cout<<"Process "<<getpid()<<", shared " <<shared<<", &shared " <<&shared<<endl; } int main(){ extern int shared; pid_t p1,p2; int status; shared=0; if ((p1=fork())==0) {func();exit(0);}; if ((p2=fork())==0) {func();exit(0);}; for(int i=0;i<10;i++) shared++; waitpid(p1,&status,0); waitpid(p2,&status,0);; cout<<"shared variable is: "<<shared<<endl; cout<<"Process "<<getpid()<<", shared " <<shared<<", &shared " <<&shared<<endl; } The two forked processes make an increment on the shared variables and the parent process does the same. As the variable belongs to the data segment of each process, the final value is 10 because the increment is independent. However, the memory address of the shared variables is the same, you can try compiling and watching the output of the program. How can that be explained ? I cannot understand that, I thought I knew how the fork() works, but this seems very odd.. I need an explanation on why the address is the same, although they are separate variables.

  • Subdomain URL Rewriting and Web Apps

    - by Igor K
    So a lot of web apps have the customer choose their own subdomain, ie mycompany.webapp.com Presumably, every subdomain works off the same set of files and the unique subdomain is perhaps stored as a session object. So how does the URL rewriting work? If someone goes to mycompany.webapp.com, you have to rewrite their unique address to a dynamic page to set the session variable, ie webapp.com/mypage.php?cusomer=mycompany But then when you redirected, you'd be at webapp.com/theappdirectory/ and not mycompany.webapp.com/ So how do they do it?

  • Change a UIButton View's background upon press

    - by Michael
    This should be easy but its got me stumped. I've got a button on each row of a table cell. The button is to delete the file associated with that row. I have an image that indicates if the file is present on the iPhone or not present. When the user presses the button, the target action method (showDeleteSheet) then calls a UIActionSheet with a variable to give it the indexPath of the row pressed. Then the user presses delete on the action sheet and the action sheet's clickedButtonAtIndex method deletes the file. Now, I need to update the button's background image property to change the image in the appropriate table cell to the not downloaded image. This can be done in either the button's target action method or the action sheet's clickedButtonAtIndex method. Here is some code: In the table's cellForRowAtIndexPath method I create the button: UIButton *deleteButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; [deleteButton addTarget:self action:@selector(showDeleteSheet:) forControlEvents:UIControlEventTouchDown]; deleteButton.frame = CGRectMake(246, 26, 30, 30); if (![AppData isDownloaded:[dets objectForKey:@"fileName"]]) { [deleteButton setBackgroundImage:notdownloadedImage forState:UIControlStateNormal]; } else { [deleteButton setBackgroundImage:notdownloadedImage forState:UIControlStateNormal]; } In the button's target method: -(void)showDeleteSheet:(id)sender { //get the cell row that the button is in NSIndexPath *indexPath = [table indexPathForCell:(UITableViewCell *)[[sender superview] superview]]; NSInteger currentSection = indexPath.section; NSInteger currentIndexRow = indexPath.row; NSLog(@"section = %i row = %i", currentSection, currentIndexRow); UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom]; [table reloadData]; //if deleteButton is declared in .h then the other instances of deleteButton show 'local declaration hides instance variable' [deleteButton setBackgroundImage:[UIImage imageNamed:@"not-downloaded.png"] forState:UIControlStateNormal]; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Delete this file?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete" otherButtonTitles:nil]; actionSheet.tag = currentIndexRow; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; [actionSheet release]; } Perhaps the issue is that the call to [deleteButton setBackgroundImage...]; doesn't know which cell's button should be updated. If so I don't know how to tell it which. Because I test if the file is downloaded when the button is made and the background image is set, when I scroll down so the cell in question is de-queued then scroll back up it show's the correct image. I've tried to force the table to reload but [table reloadData]; is doing nothing. I've tried reloadRowsAtIndexPaths and still no good. Any one care to educate me on how this is done?

  • Should I deal with files longer than MAX_PATH?

    - by John
    Just had an interesting case. My software reported back a failure caused by a path being longer than MAX_PATH. The path was just a plain old document in My Documents, e.g.: C:\Documents and Settings\Bill\Some Stupid FOlder Name\A really ridiculously long file thats really very very very..........very long.pdf Total length 269 characters (MAX_PATH==260). The user wasn't using a external hard drive or anything like that. This was a file on an Windows managed drive. So my question is this. Should I care? I'm not saying can I deal with the long paths, I'm asking should I. Yes I'm aware of the "\?\" unicode hack on some Win32 APIs, but it seems this hack is not without risk (as it's changing the behaviour of the way the APIs parse paths) and also isn't supported by all APIs . So anyway, let me just state my position/assertions: First presumably the only way the user was able to break this limit is if the app she used uses the special Unicode hack. It's a PDF file, so maybe the PDF tool she used uses this hack. I tried to reproduce this (by using the unicode hack) and experimented. What I found was that although the file appears in Explorer, I can do nothing with it. I can't open it, I can't choose "Properties" (Windows 7). Other common apps can't open the file (e.g. IE, Firefox, Notepad). Explorer will also not let me create files/dirs which are too long - it just refuses. Ditto for command line tool cmd.exe. So basically, one could look at it this way: a rouge tool has allowed the user to create a file which is not accessible by a lot of Windows (e.g. Explorer). I could take the view that I shouldn't have to deal with this. (As an aside, this isn't an vote of approval for a short max path length: I think 260 chars is a joke, I'm just saying that if Windows shell and some APIs can't handle 260 then why should I?). So, is this a fair view? Should I say "Not my problem"? Thanks! John

  • Remove querystring from URL

    What is an easy way to remove the querystring from a Path in Javascript? I have seen a plugin for Jquery that uses window.location.search. I can not do that: The URL in my case is a variable that is set from AJAX. var testURL = '/Products/List?SortDirection=dsc&Sort=price&Page=3&Page2=3&SortOrder=dsc'
