  • Localizing MVVM based WPF applications

    - by bitbonk
    What would be a good aproach to localize a MVVM based WPF allication that can change its language at runtime? Of course I could create a string property in the ViewModel for each and every string that is displayed somewhere in the View but that seems rather tedious to me. Is there a common approach/best practice for this?

  • jqgrid and django models

    - by Andrew Gee
    Hi, I have the following models class Employee(Person): job = model.Charfield(max_length=200) class Address(models.Model): street = models.CharField(max_length=200) city = models.CharField(max_length=200) class EmpAddress(Address): date_occupied = models.DateField() date_vacated = models.DateField() employee = models.ForeignKey() When I build a json data structure for an EmpAddress object using the django serialzer it does not include the inherited fields only the EmpAddress fields. I know the fields are available in the object in my view as I can print them but they are not built into the json structure. Does anyone know how to overcome this? Thanks Andrew

  • 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

  • Setting UITableViewCell button image values during scrolling

    - by Rob
    I am having an issue where I am trying to save whether a repeat image will show selected or not (it is created as a UIButton on a UITableViewCell created in IB). The issue is that since the cell gets re-used randomly, the image gets reset or set somewhere else after you start scrolling. I've looked all over and the advice was to setup an NSMutableArray to store the button's selection state and I am doing that in an array called checkRepeatState My question is: where do I put the if-then-else statement in the code to where it will actually change the button image based on if the checkRepeatState is set to 0 or 1 for the given cell that is coming back into view? Right now, the if-then-else statement I am using has absolutely no effect on the button image when it comes into view. I'm very confused at this point. Thank you ahead of time for any insight you can give!!! My code is as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // set up the cell static NSString *CellIdentifier = @"PlayerCell"; PlayerCell *cell = (PlayerCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { [[NSBundle mainBundle] loadNibNamed:@"PlayerNibCells" owner:self options:nil]; cell = tmpCell; self.tmpCell = nil; NSLog(@"Creating a new cell"); } // Display dark and light background in alternate rows -- see tableView:willDisplayCell:forRowAtIndexPath:. cell.useDarkBackground = (indexPath.row % 2 == 0); // Configure the data for the cell. NSDictionary *dataItem = [soundCategories objectAtIndex:indexPath.row]; UILabel *label; label = (UILabel *)[cell viewWithTag:1]; label.text = [dataItem objectForKey:@"AnimalName"]; label = (UILabel *)[cell viewWithTag:2]; label.text = [dataItem objectForKey:@"Description"]; UIImageView *img; img = (UIImageView *)[cell viewWithTag:3]; img.image = [UIImage imageNamed:[dataItem objectForKey:@"Icon"]]; NSInteger row = indexPath.row; NSNumber *checkValue = [checkRepeatState objectAtIndex:row]; NSLog(@"checkValue is %d", [checkValue intValue]); // Reusing cell; make sure it has correct image based on checkRepeatState value UIButton *repeatbutton = (UIButton *)[cell viewWithTag:4]; if ([checkValue intValue] == 1) { NSLog(@"repeatbutton is selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeatselected.png"] forState:UIControlStateSelected]; [repeatbutton setNeedsDisplay]; } else { NSLog(@"repeatbutton is NOT selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeat.png"] forState:UIControlStateNormal]; [repeatbutton setNeedsDisplay]; } cell.accessoryType = UITableViewCellAccessoryNone; return cell; }

  • SQL Reporting Services: Why does my report shrink when it's emailed?

  • Any way to speed up this hierarchical query?

    - by RenderIn
    I've got a serious performance problem with a hierarchical query that I can't seem to fix. I am modeling several organization charts in my database, each representing a virtual organization within our company. For example, we have several temporary committees that are created from time to time and there may be a Committee Organizer role at the top of this virtual hierarchy, with several people assigned to the Committee Member role beneath the organizer. Some of our virtual organizations have many levels and several branches at each level. I have a single table in which I represent all the role assignments. i.e. a ROLE_ID column and a PARENT_ROLE_ID column which is a foreign key to the ROLE_ID column. For each assignment we also store as a column the location in the company where this person has the assignment. For example, the Committee Organizer would have a company-level/ CEO assignment, while the committee members would have department-level assignments such as ACCOUNTING, MARKETING, etc. So to model the organizer/member relationship for two individuals we would have: ROLE_ID = 4 PARENT_ROLE_ID = NULL EMPLOYEE_NUMBER = 213423 COMPANY_LOCATION = CEO ROLE_ID = 5 PARENT_ROLE_ID = 4 EMPLOYEE_NUMBER = 838221 COMPANY_LOCATION = ACCOUNTING Here's where things get tricky. I have an application that every person in the organization can log in to. When they log in they should be able to view all the virtual organizations in our company. e.g. the committee members should be able to see the committee organizer and vice-versa. However, only the committee organizer should be able to edit the committee members. The difficulty is in determining whether an individual (who can have multiple role assignments) has edit access for each other assignment. While this seems simple in the example, consider a virtual organization in which we have President at the top, 5 departments directly beneath him, 2 subdepartments below each department. We only want people in the Accounting department to be able to edit individuals in the subdepartments belonging to the Accounting department. They should not have edit access to anybody in the Marketing department or its subdepartments. To determine edit access when a user views a virtual organization in our company I run a query that executes two inline views: A) Hierarchically query for all assignments in this virtual organization and using SYS_CONNECT_BY_PATH to store the entire path to each user/role/company_location and B) Hierarchically retrieve all the assignments the individual logged in has and using the SYS_CONNECT_BY_PATH to store the entire path to each of these assignments. The result of the query is all the records from A) plus a boolean determined by joining with B) which flags whether the logged in user has edit access for each record. Indexes don't seem to be helping... it simply appears that there is too much processing going on to separate all the records and then determine edit access. One issue is that I can't store the SYS_CONNECT_BY_PATH and index it... determining whether an individual record has edit access consists of comparing if: test_record_sys_path LIKE individual_record_sys_path || '%' Is a materialized view the answer?

    Our investigations have shown us that not all browsers respect the http cache directives in a uniform manner. For security reasons we do not want certain pages in our application to cached, ever, by the web browser. This must work for at least the following browsers: Internet Explorer versions 6-8 FireFox versions 1.5 - 3.0 Safari version 3 Opera 9 Our requirement came from a security test. After logging out from our website you could press the back button and view cached pages.

  • wrong operator() overload called

    - by user313202
    okay, I am writing a matrix class and have overloaded the function call operator twice. The core of the matrix is a 2D double array. I am using the MinGW GCC compiler called from a windows console. the first overload is meant to return a double from the array (for viewing an element). the second overload is meant to return a reference to a location in the array (for changing the data in that location. double operator()(int row, int col) const ; //allows view of element double &operator()(int row, int col); //allows assignment of element I am writing a testing routine and have discovered that the "viewing" overload never gets called. for some reason the compiler "defaults" to calling the overload that returns a reference when the following printf() statement is used. fprintf(outp, "%6.2f\t", testMatD(i,j)); I understand that I'm insulting the gods by writing my own matrix class without using vectors and testing with C I/O functions. I will be punished thoroughly in the afterlife, no need to do it here. Ultimately I'd like to know what is going on here and how to fix it. I'd prefer to use the cleaner looking operator overloads rather than member functions. Any ideas? -Cal the matrix class: irrelevant code omitted class Matrix { public: double getElement(int row, int col)const; //returns the element at row,col //operator overloads double operator()(int row, int col) const ; //allows view of element double &operator()(int row, int col); //allows assignment of element private: //data members double **array; //pointer to data array }; double Matrix::getElement(int row, int col)const{ //transform indices into true coordinates (from sorted coordinates //only row needs to be transformed (user can only sort by row) row = sortedArray[row]; result = array[usrZeroRow+row][usrZeroCol+col]; return result; } //operator overloads double Matrix::operator()(int row, int col) const { //this overload is used when viewing an element return getElement(row,col); } double &Matrix::operator()(int row, int col){ //this overload is used when placing an element return array[row+usrZeroRow][col+usrZeroCol]; } The testing program: irrelevant code omitted int main(void){ FILE *outp; outp = fopen("test_output.txt", "w+"); Matrix testMatD(5,7); //construct 5x7 matrix //some initializations omitted fprintf(outp, "%6.2f\t", testMatD(i,j)); //calls the wrong overload }

  • Cocoa: Creating a Window with a Variable Number of Interface Elements

    Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this? Create a custom view or create an empty window with a backing NSWindowController and then add stuff to it when the window is opened? I've seen the examples on the O'Reilly Cocoa book and those effectively create a custom NSView. Is this the right way to do it, 8 year later?
