  • graphics don't draw when loop condition is dates. c#, winForms

    - by jello
    so i got this piece of code. (currPosX is defined earlier) while (earliestDate < DateTime.Today) { currPosX = currPosX + 5; e.Graphics.DrawLine(Pens.Black, currPosX, 0, currPosX, 10); earliestDate = earliestDate.AddDays(1); } the graphics don't draw. it's really weird, since this only happens when the condition statement is a date comparison. I debugged, and it does go in the loop, and the values are messed with (currPosX for example). But, no display. one more weirdness, if I add a MessageBox.Show("blabla") in the loop, the message box pops up, and graphics are drawn. what's going on here?

  • What is the underlying reason for not being able to put arrays of pointers in unsafe structs in C#?

    - by cons
    If one could put an array of pointers to child structs inside unsafe structs in C# like one could in C, constructing complex data structures without the overhead of having one object per node would be a lot easier and less of a time sink, as well as syntactically cleaner and much more readable. Is there a deep architectural reason why fixed arrays inside unsafe structs are only allowed to be composed of "value types" and not pointers? I assume only having explicitly named pointers inside structs must be a deliberate decision to weaken the language, but I can't find any documentation about why this is so, or the reasoning for not allowing pointer arrays inside structs, since I would assume the garbage collector shouldn't care what is going on in structs marked as unsafe. Digital Mars' D handles structs and pointers elegantly in comparison, and I'm missing not being able to rapidly develop succinct data structures; by making references abstract in C# a lot of power seems to have been removed from the language, even though pointers are still there at least in a marketing sense. Maybe I'm wrong to expect languages to become more powerful at representing complex data structures efficiently over time.

  • Warning when using qsort in C

    - by controlfreak123
    I wrote my comparison function int cmp(const int * a,const int * b) { if (*a==*b) return 0; else if (*a < *b) return -1; else return 1; } and i have my declaration int cmp (const int * value1,const int * value2); and I'm calling qsort in my program like so qsort(currentCases,round,sizeof(int),cmp); when i compile it I get the following warning warning: passing argument 4 of ‘qsort’ from incompatible pointer type /usr/include/stdlib.h:710: note: expected ‘__compar_fn_t’ but argument is of type ‘int (*)(const int *, const int *)’ The program works just fine so my only concern is why it doesn't like the way im using that?

  • Custom Sorting on Custom Field in Django

    - by RotaJota
    In my app, I have defined a custom field to represent a physical quantity using the quantities package. class AmountField(models.CharField): def __init__(self, *args, **kwargs): ... def to_python(self, value): create_quantities_value(value) Essentially the way it works is it extends CharField to store the value as a string in the database "12 min" and represents it as a quantities object when using the field in a model array(12) * min Then in a model it is used as such: class MyModel(models.Model): group = models.CharField() amount = AmountField() class Meta: ordering = ['group', 'amount'] My issue is that these fields do not seem to sort by the quantity, but instead by the string. So if I have some objects that contain something like {"group":"A", "amount":"12 min"} {"group":"A", "amount":"20 min"} {"group":"A", "amount":"2 min"} {"group":"B", "amount":"20 min"} {"group":"B", "amount":"1 hr"} they end up sorted something like this: >>> MyModel.objects.all() [{A, 12 min}, {A, 2 min}, {A, 20 min}, {B, 1 hr}, {B, 20 min}] essentially alphabetical order. Can I give my custom AmountField a comparison function so that it will compare by the python value instead of the DB value?

  • How to make an NSOutlineView indent multiple columns?

    - by Rinzwind
    What would be the easiest or recommended way for making an NSOutlineView indent multiple columns? By default, it only indents the outline column; and as far as I know there is no built-in support for making it indent other columns. I have an NSOutlineView which shows a comparison between two sets of hierarchical data. For visual appeal, if some item in the outline column is indented, I'd like to indent the item on the same row in another column by the same indentation amount. (There's also a third column which shows the result of comparing the two items, this column should never be indented.) Can this only be achieved by subclassing NSOutlineView? And what would need to be overridden in the subclass? Or is there an easier way to get it to indent multiple columns?

  • How to convert a plist file from mac os project to iphone project?

    - by Tom Pace
    I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's plist files are Mac OSX project plist files. This is an iPhone engine, and so I cannot understand why the plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings.

  • How to differentiate new items from existing items in SharePoint workflow

    - by Jim Hoerber
    I have a SPD workflow that is set to run when an item changes but it keeps getting triggered on new items, which is pretty annoying. I'm looking into why this is happening but I'm also looking for a way to terminate the workflow if the item is new as a temporary workaround. I tried to compare the Created field to the Modified field i.e. if Created and Modified are the same then don't run. This didn't work, either as a date or string comparison. Any suggestions would be much appreciated.

  • Nonstandard SSIS lookup

    - by Stefan
    I have a situation where I am trying to lookup a value in one table based on values in another table, using a BETWEEN operator and not an = operator. In one table, I have a value "EffectiveDate". I want to get a Weight number from another table, but the other table has two fields: "Inception" and "Termination". What I want to do is extract the Weight from that table for use where the EffectiveDate is between Inception and Termination. SSIS doesn't seem to provide a way to do this. It's good at matching one column to another column, but doesn't seem to allow one to many-column comparison/operations. Am I missing anything? Is this possible to do somehow?

  • Crystal Reports: global variable running total not displaying in header

    - by phill
    Using Crystal Reports I'm trying to display the running total of a database field in the header where all the labels are. I've attempted to do this by placing the running total (RTversion) into a formula field with the following: Shared stringvar CurrentVers; CurrentVers := {#CurrentVers}; and then in the page header section I have the following: Shared stringvar CurrentVers; EvaluateAFter({#currentVers}); CurrentVers; with {#CurrentVers} running the 1st largest number. Is this incorrect? Update: The goal is to display the latest version in the header near the labels to show what the current verseion is for comparison.

  • ESRI frameworks: java vs javascript

    - by Luke
    I'm about to develop a web mapping application with ESRI Products like ArcGIS Server and Image Server. I can't find a good comparison between the Java Web ADF and the Javascript Framework. They're of course different because one is a full environment and the other is only client side but it's much more concise and the step to start is minimal. Another problem is that the Java Web ADF is not compatible with our current application server (JBoss 4.2.2) and require an old 4.0.2 version. Someone out there has experience that can help me? Many thanks.

  • I wanted to be a programmer

    - by Henrik P. Hessel
    Hello, let me ask your opinion. I'm 25 now, living in Germany. I started with QBASIC, did some Java in Highschool, and after School I created some Websites in PHP. Now, because my Company is Microsoft Gold Partner, I've to use Microsoft all the time. C#, MSSQL, ASPX and Sharepoint <- I really hate it! So, in my spare I concentrate to gain more knowledge (C++, Java, Silverlight or WPF), because it feels that I'm so far behind, in comparison for example to you guys, or other older employees in my company. Do think that my behaviour is useful? Should I focus my time to become i.e. a pure C# Programmer? I did C# even before I started to learn some C++. Should I learn what do with pointers, memcpy and stuff like that, even if managed code brings us so much benefits? Or is it a waste of time, better invested in learning the latest technologies? rAyt

  • Python - compare nested lists and append matches to new list?

    - by Seafoid
    Hi, I wish to compare to nested lists of unequal length. I am interested only in a match between the first element of each sub list. Should a match exist, I wish to add the match to another list for subsequent transformation into a tab delimited file. Here is an example of what I am working with: x = [['1', 'a', 'b'], ['2', 'c', 'd']] y = [['1', 'z', 'x'], ['4', 'z', 'x']] match = [] def find_match(): for i in x: for j in y: if i[1] == j[1]: match.append(j) return match This results in a series of empty lists. Is it better to use tuples and/or tuples of tuples for the purposes of comparison? Any help is greatly appreciated. Regards, Seafoid.

This is the line of code I've if (HttpContext.Current != null && HttpContext.Current.Request != null) and an exception is being thrown for second comparison.

  • Window 'onscreen' size puzzle

    - by Bender
    Okay, a REALLY fundamental question about window sizes here... If I create an NSWindow in IB, set its size to 216 x 144 points (exactly 3 inches by 2 inches) then print the window, it measures exactly what I set it to in IB. However, the onscreen display size measures approximately 156 x 105 points. What causes this, and is there any way to force the window to display at the required size onscreen? I ultimately want to draw to this (semi-transparent) window then use it as a full-sized overlay for comparison against a separately loaded scanned image of known size.

  • How can i query for null values in entity framework?

    - by AZ
    I want to execute a query like this var result = from entry in table where entry.something == null select entry; and get an IS NULL generated. Edited: After the first two answers i feel the need to clarify that I'm using Entity Framework and not Linq to SQL. The object.Equals() method does not seem to work in EF. Edit no.2: The above query works as intended. It correctly generates IS NULL. My production code however was var value = null; var result = from entry in table where entry.something == value select entry; and the generated SQL was something = @p; @p = NULL. It seems that EF correctly translates the constant expression but if a variable is involved it treats it just like a normal comparison. Makes sense actually. I'll close this question

  • Avoiding Mixup of Language Details

    - by DarenW
    Today someone asked me what was wrong with their source code. It was obvious. "Use double equals in place of that single equal in that if statement. Um, i think..." As i remember some languages actually take a single equals for comparison. Since i sometimes forget or mix up the syntax details among the several languages i use, i stepped over to my laptop to try a quickie experiment... It costs a bit of time and is a break in the flow to try "quick" experiments (though maybe the practice is good for memory.) What tips do you have for keeping straight in your mind the syntax (and other) details of multiple languages? (And nowadays, this applies just as well to the many wiki-like markups!)

SELECT * FROM dbo.table1 WHERE dbo.RegexMatch(column1, '[0-9][A-Z]') = 1 -- match entries in col1 like 1A, 2B etc... I'm just thinking it would be nice to reformulate that query so it could be called like SELECT * FROM dbo.table1 WHERE column1 REGEXLIKE '[0-9][A-Z]' Is it possible to create new comparison operators using CLR Code. (I'm guessing from my brief glance around the web that the answer is NO, but no harm asking)

  • What is your ratio Bug fixing vs Enhancements ?

    - by Newtopian
    In the spirit of this question I wanted to have a sense of what is the proportion of time split between fixing bugs and implementing new features. If possible try to give an estimate for the product as a whole as opposed to individual developer stats and try to make an average over the course of a typical year. Do provide a general descriptive of the product/project to allow comparison. Specifically : Maturity of project Is it still actively developed or strictly in maintenance ? Size estimate of the product/project Size of team developing it (all inclusive) What is your team score on the Joel test. Ex : approx 80% time spent bug fixes 20% new stuff Mature software (20 years old) Actively developed 1.5M Line of Text, approx 700k - 900k LOC 12-15 actively coding in it. we got 5/12 for sure, some would say 7/12.

  • The fastest way to do a collection subtraction

    - by Tony
    I have two Sets. Set<B> b is the subset of Set<A> a. they're both very huge Sets. I want to subtract b from a , what's the best practice to do this common operation ? I've written to many codes like this , and I don't think it's efficient. what's your idea ? for(int i = 0 ; i < a.size(); i++) { for (int j=0 ; j < b.size() ;j++) { // do comparison , if found equals ,remove from a break; } } And I want to find an algorithm , not only applies to Sets, also works for Array.

  • SQL Server 2005 script with join across Database Servers

    - by Robin Day
    I have the following script which I use to give me a simple "diff" between tables on two different databases. (Note: In reality my comparison is on a lot more than just an ID) SELECT MyTableA.MyId, MyTableB.MyId FROM MyDataBaseA..MyTable MyTableA FULL OUTER JOIN MyDataBaseB..MyTable MyTableB ON MyTableA.MyId = MyTableB.MyId WHERE MyTableA.MyId IS NULL OR MyTableB.MyId IS NULL I now need to run this script on two databases that exist on different servers. At the moment my solution is to backup the database from one server, restore it to the other and then run the script. I'm pretty sure this is possible, however, is this likely to be a can of worms? This is a very rare task I need to perform and if it involves a large number of DB setting changes then I will probably stick to my backup method.

  • When to use Spring Integration vs. Camel?

    - by ngeek
    As a seasoned Spring user I was assuming that Spring Integration would make the most sense in a recent project requiring some (JMS) messaging capabilities (more details). After some days working with Spring Integration it still feels like a lot of configuration overhead given the amount of channels you have to configure to bring some request-response (listening on different JMS queues) communications in place. Therefore I was looking for some background information how Camel is different from Spring Integration, but it seems like information out there are pretty spare, I found: http://java.dzone.com/articles/spring-integration-and-apache (Very neutral comparison between implementing a real-world integration scenario in Spring Integration vs. Camel, from December 2009) http://hillert.blogspot.com/2009/10/apache-camel-alternatives.html (Comparing Camel with other solutions, October 2009) http://raibledesigns.com/rd/entry/taking_apache_camel_for_a (Matt Raible, October 2008) Question is: what experiences did you make on using the one stack over the other? In which scenarios would you recommend Camel were Spring Integration lacks support? Where do you see pros and cons of each? Any advise from real-world projects are highly appreciated.
