  • How to query collections in NHibernate

    - by user305813
    Hi, I have a class: public class User { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IDictionary<string, string> Attributes { get; set; } } and a mapping file: <class name="User" table="Users"> <id name="Id"> <generator class="hilo"/> </id> <property name="Name"/> <map name="Attributes" table="UserAttributes"> <key column="UserId"/> <index column="AttributeName" type="System.String"/> <element column="Attributevalue" type="System.String"/> </map> </class> So now I can add many attributes and values to a User. How can I query those attributes so I can get ie. Get all the users where attributename is "Age" and attribute value is "20" ? I don't want to do this in foreach because I may have millions of users each having its unique attributes. Please help

  • iPhone: Cell imageViews repeating when loaded from url

    - by araid
    I'm developing a demo RSS reader for iPhone. I obviously have a tableview to display the feeds, and then a detailed view. Some of this feeds have a thumbnail that I want to display on cell.imageview of the table, and some don't. The problem is that when scrolling the table, loaded thumbnails start repeating on other cells, and I end up with a thumbnail on every cell. Here's a piece of my code. I may upload screenshots later - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: @"rssItemCell"]; if(nil == cell){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"rssItemCell"]autorelease]; } BlogRss *item = [[[self rssParser]rssItems]objectAtIndex:indexPath.row]; cell.textLabel.text = [item title]; cell.detailTextLabel.text = [item description]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; // Thumbnail if exists if(noticia.imagePath != nil){ NSData* imageData; @try { imageData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:item.imagePath]]; } @catch (NSException * e) { //Some error while downloading data } @finally { item.image = [[UIImage alloc] initWithData:imageData]; [imageData release]; } } if(item.image != nil){ [[cell imageView] setImage:item.image]; } return cell; } Any help will be very appreciated.

  • python calendar to calculate month backwards

    - by Suhail
    Hi, we are trying to create a calendar function in python. we have created a small content management system, the requirement is, there will be a drop down list on the top right hand corner of the website, which will give the options - Months - 1 month, 2 months, 3 months and so on..., if the user selects 8 months then it should show the postscount for the last 8 months. the issue is we tried to write a small code which would do the month calculations, but the bug is that it does not consider the months beyond the current year, it shows the postscount only for months of the current year. for example: if the user selects 3 months, it will show the count for the l 3 months i.e present month and the previous 2 months, but if the user selects option more than 4 months, it does not consider the months from previous year, it still shows the month of the present year only. I am pasting the code below:- def __getSpecifiedMailCount__(request, value): dbconnector= DBConnector() CdateList= "select cdate from mail_records" DateNow= datetime.datetime.today() DateNow= DateNow.strftime("%Y-%m") DateYear= datetime.datetime.today() DateYear= DateYear.strftime("%Y") DateMonth= datetime.datetime.today() DateMonth= DateMonth.strftime("%m") #print DateMonth def getMonth(value): valueDic= {"01": "Jan", "02": "Feb", "03": "Mar", "04": "Apr", "05": "May", "06": "Jun", "07": "Jul", "08": "Aug", "09": "Sep", "10": "Oct", "11": "Nov", "12": "Dec"} return valueDic[value] def getMonthYearandCount(yearmonth): MailCount= "select count(*) as mailcount from mail_records where cdate like '%s%s'" % (yearmonth, "%") MailCountResult= MailCount[0]['mailcount'] return MailCountResult MailCountList= [] MCOUNT= getMonthYearandCount(DateNow) MONTH= getMonth(DateMonth) MailCountDict= {} MailCountDict['monthyear']= MONTH + ' ' + DateYear MailCountDict['mailcount']= MCOUNT var_monthyear= MONTH + ' ' + DateYear var_mailcount= MCOUNT MailCountList.append(MailCountDict) i=1 k= int(value) hereMONTH= int(DateMonth) while (i < k): hereMONTH= int(hereMONTH) - 1 if (hereMONTH < 10): hereMONTH = '0' + str(hereMONTH) if (hereMONTH == '00') or (hereMONTH == '0-1'): break else: PMONTH= getMonth(hereMONTH) hereDateNow= DateYear + '-' + PMONTH hereDateNowNum= DateYear + '-' + hereMONTH PMCOUNT= getMonthYearandCount(hereDateNowNum) MailCountDict= {} MailCountDict['monthyear']= PMONTH + ' ' + DateYear MailCountDict['mailcount']= PMCOUNT var_monthyear= PMONTH + ' ' + DateYear var_mailcount= PMCOUNT MailCountList.append(MailCountDict) i = i + 1 #print MailCountList MailCountDict= {'monthmailcount': MailCountList} reportdata = MailCountDict['monthmailcount'] #print reportdata return render_to_response('test.html', locals())

  • Delphi, PGDac vs Zeos, Fetch, Lookup?

    - by durumdara
    Hi! I used Zeos to test to know: is ZTable uses fetch technics, or not? May in the future we migrate our lesser system to PGSQL, and this used now "Table" components (as BDE, but it have an SQL-like server). These tables use real cursors, a "Window" with N record, so lookup is very fast, because the Locate/Lookup is started on server, and only these N records are refreshed, no matter, how many records in the lookup table. PGSQL uses fetch technics as I know, and I tested it with a table (id int, name varchar(100)), and 1 million records. (I also trying this with mysql). The adapter is Zeos. ID, sec to find, allocated memory in bytes on client. MySQL 500000 2,761 113 196 344 1000000 3,214 225 471 232 313800 0,437 225 471 232 328066 0,468 225 471 232 276374 0,390 225 471 232 905984 1,264 225 471 232 260253 0,359 225 471 232 PGSQL 500000 3,042 113 188 184 1000000 3,744 225 463 064 313800 0,436 225 463 064 328066 0,452 225 463 064 276374 0,375 225 463 064 905984 1,295 225 463 064 260253 0,359 225 463 064 142023 0,203 225 463 064 As you see the records are fetched locally, this cause the 225 MB usage, and searches are slow a little, based where is the record we must find. I want to ask more things: a.) Is PGDAC have some technics to we can use the lookups without pay the fetch with memory and secs? b.) Or is PG ODBC driver can help in this problem with ADO? (As I know ADO can use server side cursors)? c.) Have anybody some experience with lookup tables, and performance? Is this critical question or it is not? (With client memory usage too). d.) If no chance to avoid fetch hell with lookups, what we can do? Server Side Joins, and unique code for Lookup field changing without real Lookup? Thanks for your help: dd

  • Fatal error when using FILE* in Windows from DLL

    - by AlannY
    Hi there. Recently, I found a problem with Visual C++ 2008 compiler, but using minor hack avoid it. Currently, I cannot use the same hack, but problem exists as in 2008 as in 2010 (Express). So, I've prepared for you 2 simple C file: one for DLL, one for program: DLL (file-dll.c): #include <stdio.h> __declspec(dllexport) void print_to_stream (FILE *stream) { fprintf (stream, "OK!\n"); } And for program, which links this DLL via file-dll.lib: Program: #include <stdio.h> __declspec(dllimport) void print_to_stream (FILE *stream); int main (void) { print_to_stream (stdout); return 0; } To compile and link DLL: cl /LD file-dll.c To compile and link program: cl file-test.c file-dll.lib When invoking file-test.exe, I got the fatal error (similar to segmentation fault in UNIX). As I said early, I had that the same problem before: about transferring FILE* pointer to DLL. I thought, that it may be because of compiler mismatch, but now I'm using one compiler for everything and it's not the problem. ;-( What can I do now? UPD: I've found solution: cl /LD /MD file-dll.c cl /MD file-test.c file-dll.lib The key is to link to dynamic library, but (I did not know it) by default it links staticaly and (hencefore) error occurs (I see why). P.S. Thanks for patience.

  • How to create minidump of a .NET process when a certain first chance exception occurs.

    - by mark
    Dear ladies and sirs. My application throws InvalidCastException in the QA environment, something I cannot reproduce in development. I wish to obtain the minidump at the exception moment. I know about adplus, but I am not sure how to use it so that it creates the minidump when InvalidCastException is thrown. Apparently, it does not distinguish one .NET exception from another. May be I am wrong and there is a way. Or, there is another tool to do it. Preferably free one. Anyway, can anyone advice how to handle this issue? Thanks. UPDATE The build is a Debug build in both QA and dev. However, QA runs complex scenarios made possible in the lab, which devs cannot reproduce. Hence I need an ability to make dump when running in QA. I can modify the code and create minidump from code. However, I wish for a more flexible solution, the one not requiring to modify the code every time an issue like this occurs.

  • Integrating Magento with SAP ECC 6.0 Backend

    - by ikarous
    I'm a freshly graduated (read: inexperienced) developer who's been tasked with determining the feasibility of integrating Magento with an SAP-based backend. No developer at our company has any experience working with either SAP or Magento, so I was hoping that the Stack Overflow community may be able to point me in the right direction with my research. We're a small company (four full-time developers) and the timeline on this project would be tight, so I'm trying to gather as much information as possible. The client has a tiered pricing structure, tax calculation logic, promotional deals, and automatic freight determination all implemented in an SAP ECC 6.0 system. They would like to migrate all their online stores over to Magento while continuing to utilize all existing functionality in SAP. The idea is to accomplish this by overriding certain modules in Magento to place remote calls to SAP BAPIs. I've investigated SAPRFC, which looks promising but relatively stale in terms of update frequency. Do any developers have experience using SAPRFC with SAP ECC 6.0 (with or without Magento integration)? If so, what were your experiences, and what were the biggest risk factors involved? Any comments, suggestions, or links to resources would be greatly appreciated.

  • Why does my DataTemplate break the WPF designer?

    - by PRINCESS FLUFF
    Why does the DataTemplate line break the WPF designer in Visual Studio 2008? The program compiles and runs properly. The DataTemplate is applied as it should. However the entire DataTemplate block of code is underlined in red, and when I simply "build" the program without running, I get the error "Type reference cannot find public type named 'Character'" How come it can't find it in the designer yet the program applies the template properly? <UserControl x:Class="WPF_Tests.Tests.TwoCollecViews.TwoViews" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:DetailsPane="clr-namespace:WPF_Tests.Tests.DetailsPane" > <UserControl.Resources> <DataTemplate DataType="{x:Type DetailsPane:Character}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Name}"></TextBlock> </StackPanel> </DataTemplate> </UserControl.Resources> <Grid> <ListBox ItemsSource="{Binding Path=Characters}" /> </Grid> </UserControl> EDIT: I am being told that this may be a bug in Visual Studio 2008, as it worked correctly in 2010. You can download the code here: http://www.mediafire.com/?z1myytvwm4n - The Test/TwoCollec xaml file's designer will break with this code.

  • Internal bug tracking tickets - Redmine, Trac, or JIRA

    - by Tai Squared
    I've been looking at setting up Redmine, Trac, or JIRA to track issues. I want to be able to have my development team create internal tickets that are never seen by clients, while clients can create/edit tickets that are seen by the internal team. From the Trac documentation, you can set permissions to create or view tickets, but it doesn't seem to allow for viewing only certain tickets. It may be possible with Trac Fine Grained Permissions, but doesn't appear so. The Redmine documentation mentions: Define your own roles and set their permissions in a click but doesn't appear to have the level of granularity. From the JIRA documentation: At the moment JIRA is only able to support security at a project level or issue level. Currently there is no field level security available. According to this question, Redmine doesn't support internal tickets, so you would have to use multiple projects. I don't want a situation where I would have to create multiple projects - one internal, one external and have the external tickets brought into the internal repository. It seems as this would lead to unnecessary overhead and inevitably, the projects wouldn't be in sync. Is there any way with any of these products (possibly through a plug-in if not in the core product itself) to specify these permissions, or simplify having two projects with different users and permissions that must still share information?

  • PHP (A few questions) OO, refactoring, eclipse

    - by jax
    I am using PHP in eclipse. It works ok, I can connect to my remote site, there is colour coding of code elements and some code hints. I realise this may be too long to answer all questions, if you have a good answer for one part, answering just that is ok. Firstly General Coding I have found that it is easy to loose track of included files and their variables. For example if there was a database $cursor it is difficult to remember or even know that it was declared in the included file (this becomes much worse the more files you include). How are people dealing with this? How are people documenting their code - in particular the required GET and POST data? Secondly OO Development: Should I be going full OO in my development. Currently I have a functions library which I can include and have separated each "task" into a separate file. It is a bit nasty but it works. If I go OO how do I structure the directories in PHP, java uses packages - what about php? How should I name my files, should I use all lower case with _ for spaces "hello_world.php"? Should I name classes with Uppercase like Java "HelloWorld.php"? Is there a different naming convention for Classes and regular function files? Thirdly Refactoring I must say this is a real pain. If I change the name of a variable in one place I have to go through whole document and each file that included this file and change the name their too. Of course, errors everywhere is what results. How are people dealing with this problem? In Java if you change the name in one place it changes everywhere. Are there any plugins to improve php refactoring? I am using the official PHP version of Eclipse from their website. thanks

  • Is it possible to write a class that interacts with controls on my WPF form?

    - by Adam S
    Hi all, I'm trying to write a class that I can use to interact with a group of similar controls in my wpf application. I have hit a few roadblocks and now I am wondering if this is a poor approach to begin with. I want to do this primarily to make my code more manageable - I have to interact with around 200 - 300 controls with my code, and it could get very tricky to have all my code in the main window class. Here's something I'd like to be able to do: class ProcControl { private CheckBox * [] Boxes = new CheckBox[10]; ProcControl() { //set boxes 0-9 to point to the actual checkboxes } //provides mass checking/unchecking functionality public void Refactor(CheckBox box) { //see what box it is int box_index = 0; while (Boxes[box_index] != box) { box_index++; } } } This doesn't work as it is right now. I have not figured out how to get my Boxes[] array to point to the actual checkboxes on my form, so I can't interact with them yet. Is it even possible to make an array that points to a bunch of controls so that I may process their properties in a nice manner? Why can't I access the controls at all from inside my class?

  • DDD: Persisting aggregates

    - by Mosh
    Hello, Let's consider the typical Order and OrderItem example. Assuming that OrderItem is part of the Order Aggregate, it an only be added via Order. So, to add a new OrderItem to an Order, we have to load the entire Aggregate via Repository, add a new item to the Order object and persist the entire Aggregate again. This seems to have a lot of overhead. What if our Order has 10 OrderItems? This way, just to add a new OrderItem, not only do we have to read 10 OrderItems, but we should also re-insert all these 10 OrderItems again. (This is the approach that Jimmy Nillson has taken in his DDD book. Everytime he wants to persists an Aggregate, he clears all the child objects, and then re-inserts them again. This can cause other issues as the ID of the children are changed everytime because of the IDENTITY column in database.) I know some people may suggest to apply Unit of Work pattern at the Aggregate Root so it keeps track of what has been changed and only commit those changes. But this violates Persistence Ignorance (PI) principle because persistence logic is leaking into the Domain Model. Has anyone thought about this before? Mosh

  • Accessing Static Methods on a Generic class in c#

    - by mrlane
    Hello, I have the following situation in code, which I suspect may be a bit dodgey: I have a class: abstract class DataAccessBase<T> : IDataAccess where T : AnotherAbstractClass This class DataAccessBase also has a static factory method which creates instances of derived classes of itself using an enum value in a which statement to decide which derived type to create: static IDataAccess CreateInstance(TypeToCreateEnum) Now, the types derived from DataAccessBase<T> are themselves NOT generic, they specify a type for T: class PoLcZoneData : DataAccessBase<PoLcZone> // PoLcZone is derived from AnotherAbstractClass So far I am not sure if this is pushing the limits of good use of generics, but what I am really concerned about is how to access the static CreateInstance() method in the first place: The way I am doing this at the moment is to simply pass any type T where T : AnotherAbstractClass. In particular I am passing AnotherAbstractClass itself. This allows compilation just fine, but it does seem to me that passing any type to a generic class just to get at the statics is a bit dodgey. I have actually simplified the situation somewhat as DataAccessBase<T> is the lower level in the inheritance chain, but the static factory methods exists in a middle tier with classes such as PoLcZoneData being the most derived on the only level that is not generic. What are peoples thoughts on this arrangement?

  • What is the correct way to implement a massive hierarchical, geographical search for news?

    - by Philip Brocoum
    The company I work for is in the business of sending press releases. We want to make it possible for interested parties to search for press releases based on a number of criteria, the most important being location. For example, someone might search for all news sent to New York City, Massachusetts, or ZIP code 89134, sent from a governmental institution, under the topic of "traffic". Or whatever. The problem is, we've sent, literally, hundreds of thousands of press releases. Searching is slow and complex. For example, a press release sent to Queens, NY should show up in the search I mentioned above even though it wasn't specifically sent to New York City, because Queens is a subset of New York City. We may also want to implement "and" and "or" and negation and text search to the query to create complex searches. These searches also have to be fast enough to function as dynamic RSS feeds. I really don't know anything about search theory, or how it's properly done. The way we are getting by right now is using a data mart to store the locations the releases were sent to in a single table. However, because of the subset thing mentioned above, the data mart is gigantic with millions of rows. And we haven't even implemented cities yet, and there are about 50,000 cities in the United States, which will exponentially increase the size of the data mart by so much I'm afraid it just won't work anymore. Anyway, I realize this is not a simple question and there won't be a "do this" answer. However, I'm hoping one of you can point me in the right direction where I can learn about how massive searches are done? Because I really know nothing about it. And such a search engine is turning out to be incredibly difficult to make. Thanks! I know there must be a way because if Google can search the entire internet we must be able to search our own database :-)

  • Adding time zone hours difference to time

  • C# naming convention for enum and matching property

    - by Serge - appTranslator
    Hi All, I often find myself implementing a class maintaining some kind of own status property as an enum: I have a Status enum and ONE Status property of Status type. How should I solve this name conflict? public class Car { public enum Status { Off, Starting, Moving }; Status status = Status.Off; public Status Status // <===== Won't compile ===== { get { return status; } set { status = value; DoSomething(); } } } If the Status enum were common to different types, I'd put it outside the class and the problem would be solved. But Status applies to Car only hence it doesn't make sense to declare the enum outside the class. What naming convention do you use in this case? NB: This question was partially debated in comments of an answer of this question. Since it wasn't the main question, it didn't get much visibility. EDIT: Filip Ekberg suggests an IMO excellent workaround for the specific case of 'Status'. Yet I'd be interesting to read about solutions where the name of the enum/property is different, as in Michael Prewecki's answer. EDIT2 (May 2010): My favorite solution is to pluralize the enum type name, as suggested by Chris S. According to MS guidelines, this should be used for flag enums only. But I've come to like it more and more. I now use it for regular enums as well.

  • Delphi Mock Wizard

    - by Todd
    Let me preface this by saying I'm fairly new to Unit Testing, Mocks, Stubs, Etc... I've installed Delphi-Mock-Wizard. When I select a unit and "Generate Mock", a new unit is created but it's very basic and not anything what I understand Mocks to be. unit Unit1; (** WARNING - AUTO-GENERATED MOCK! Change this unit if you want to, but be aware that any changes you make will be lost if you regenerate the mock object (for instance, if the interface changes). My advice is to create a descendent class of your auto-generated mock - in a different unit - and override things there. That way you get to keep them. Also, the auto-generate code is not yet smart enough to generate stubs for inherited interfaces. In that case, change your mock declaration to inherit from a mock implementation that implements the missing interface. This, unfortunately, is a violation of the directive above. I'm working on it. You may also need to manually change the unit name, above. Another thing I am working on. **) interface uses PascalMock, TestInterfaces; type IThingy = interface; implementation end. Looking at the source there seems to be quite a bit commented out. I'm wondering, has anyone gotten this to work? My IDE is D2010. Thanks.

  • loading child swf as3

    - by RichW
    Hi, I've been given an fla to make some changes too. Basically its a fairly long timeline animation with sound. So far I've successfully added a few button functions for sound etc.. but one has got me stumped. One of the buttons needs to load a child swf. I'm using the code below but I'm recieving an error - 'Error #1009: Cannot access a property or method of a null object reference'. I believe this may be refferring to an object that isn't set yet but I have no idea which one it is: Code: var mcExt:MovieClip = new MovieClip(); var ldr:Loader = new Loader(); ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded); ldr.load(new URLRequest("Downloads.swf")); function swfLoaded(e:Event):void { mcExt = MovieClip(ldr.contentLoaderInfo.content); ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded); mcExt.x = 50; mcExt.y = 50; addChild(mcExt); } Any help on what is going wrong would be greatly appreciated!

  • Malloc inside another function (ANSI C)

    - by Casper
    Hi I'll go straight to it. I'm working on an assignment, where I suddenly ran into trouble. I have to allocate a struct from within another function, obviously using pointers. I've been staring at this problem for hours and tried in a million different ways to solve it. This is some sample code (very simplified): ... some_struct s; printf("Before: %d\n", &s"); allocate(&s); printf("After: %d\n", &s"); ... /* The allocation function */ int allocate(some_struct *arg) { arg = malloc(sizeof(some_struct)); printf("In function: %d\n", &arg"); return 0; } This does give me the same address before and after the allocate-call: Before: -1079752900 In function: -1079752928 After: -1079752900 I know it's probably because it makes a copy in the function, but I don't know how to actually work on the pointer I gave as argument. I tried defining some_struct *s instead of some_struct s, but no luck. I tried with: int allocate(some_struct **arg) which works just fine (the allocate-function needs to be changed as well), BUT according to the assignment I may NOT change the declaration, and it HAS to be *arg.. And it would be most correct if I just have to declare some_struct s.. Not some_struct *s. I hope I make sense and some of you out there can help me :P Thanks in advice

  • UTF-8 to Unicode conversion

    - by sandeep
    Hi, I am having problems with converting UTF-8 to Unicode. Below is the code: int charset_convert( char * string, char * to_string,char* charset_from, char* charset_to) { char *from_buf, *to_buf, *pointer; size_t inbytesleft, outbytesleft, ret; size_t TotalLen; iconv_t cd; if (!charset_from || !charset_to || !string) /* sanity check */ return -1; if (strlen(string) < 1) return 0; /* we are done, nothing to convert */ cd = iconv_open(charset_to, charset_from); /* Did I succeed in getting a conversion descriptor ? */ if (cd == (iconv_t)(-1)) { /* I guess not */ printf("Failed to convert string from %s to %s ", charset_from, charset_to); return -1; } from_buf = string; inbytesleft = strlen(string); /* allocate max sized buffer, assuming target encoding may be 4 byte unicode */ outbytesleft = inbytesleft *4 ; pointer = to_buf = (char *)malloc(outbytesleft); memset(to_buf,0,outbytesleft); memset(pointer,0,outbytesleft); ret = iconv(cd, &from_buf, &inbytesleft, &pointer, &outbytesleft);ing memcpy(to_string,to_buf,(pointer-to_buf); } main(): int main() { char UTF []= {'A', 'B'}; char Unicode[1024]= {0}; char* ptr; int x=0; iconv_t cd; charset_convert(UTF,Unicode,"UTF-8","UNICODE"); ptr = Unicode; while(*ptr != '\0') { printf("Unicode %x \n",*ptr); ptr++; } return 0; } It should give A and B but i am getting: ffffffff fffffffe 41 Thanks, Sandeep

  • Static variables and long running thread on IIS 7.5

    - by Dmitry
    Hello people. Help me solve next problem. I have ASP .NET MVC2 application. I run it on IIS 7.5. In one page user clicks button and handler for this button sends request to server (jquery.ajax). At server action in controller starts new thread (it makes long time import): var thread = new Thread(RefreshCitiesInDatabase); thread.Start(); State of import is available in static variable. New thread changes value of variable in the begin of work. User can check state of import too with the help of this variable, which is used in view. And user sees import's state. When I start this function few minutes everything is okey. On page I see right state of import, quantity of imported records is changed, I see changes in logs. But after few minutes begin troubles. When I refresh page with import state sometimes I see that import is okey but sometimes I see page with default values about import (like application is just started), but after that again I can see page with normal import's state. I tried to attach Visual Studio to IIS process and debug application. But when request comes to controller sometimes static variables have right values and sometimes they have default values (static int has 0, static string has "" etc.). Tell me what I do wrong. May be I must start additional thread in other way? Thanks in advance, Dmitry

  • What is your workflow when designing HTML/CSS layouts?

    - by DMin
    I have been working with PHP/MySQL as a hobby for close to a couple of years now, I have been working with photoshop for a very long time, I know CSS & HTML well enough to write without any reference, so, I would not consider myself someone who's very new at this. I have recently started developing websites professionally - (only person working on the project). I have seen the power of Joomla and how you can make a website ready for your customer in a matter of hours(if not minutes). I find it very hard to make layouts that remotely look like the themes on joomla. I find making even simple layouts a very cumbersome process and takes a lot of time to get a good enough output. I have a feeling I may not be using the right tools or workflow for the job. What I wanted to findout was, as part of the industry : How do, you, make your website when you do it from scratch? What are the tools that you use? What is your workflow? Just noted a few things I know already, for your reference(You can skip this if you like) I have seen the export for web for Photoshop that exports CSS - but (as far as I know) exports only absolutely positioned webpages so they need to be beaten and fixed if you want to use them for example for joomla. I have used the SiteGrinder plugin for Photoshop that exports HTML/CSS. It looks promising but haven't tried it extensively. One of the tools that save loads of time is FireBug. This makes it easy to edit html and css on the fly and get the page looking exactly as you want it. Recently stumbled upon fireworks. But haven't explored it much. Thanks! :)

  • Automation Error when exporting Excel data to SQL Server

    - by brohjoe
    I'm getting an Automation error upon running VBA code in Excel 2007. I'm attempting to connect to a remote SQL Server DB and load data to from Excel to SQL Server. The error I get is, "Run-time error '-2147217843(80040e4d)': Automation error". I checked out the MSDN site and it suggested that this may be due to a bug associated with the sqloledb provider and one way to mitigate this is to use ODBC. Well I changed the connection string to reflect ODBC provider and associated parameters and I'm still getting the same error. Here is the code with ODBC as the provider: Dim cnt As ADODB.Connection Dim rst As ADODB.Recordset Dim stSQL As String Dim wbBook As Workbook Dim wsSheet As Worksheet Dim rnStart As Range Public Sub loadData() 'This was set up using Microsoft ActiveX Data Components version 6.0. 'Create ADODB connection object, open connection and construct the connection string object. Set cnt = New ADODB.Connection cnt.ConnectionString = "Driver={SQL Server}; Server=onlineSQLServer2010.foo.com; Database=fooDB;Uid=logonalready;Pwd='helpmeOB1';" cnt.Open On Error GoTo ErrorHandler 'Open Excel and run query to export data to SQL Server. strSQL = "SELECT * INTO SalesOrders FROM OPENDATASOURCE('Microsoft.ACE.OLEDB.12.0'," & _ "'Data Source=C:\Database.xlsx; Extended Properties=Excel 12.0')...[SalesOrders$]" cnt.Execute (strSQL) 'Error handling. ErrorExit: 'Reclaim memory from the connection objects Set rst = Nothing Set cnt = Nothing Exit Sub ErrorHandler: MsgBox Err.Description, vbCritical Resume ErrorExit 'clean up and reclaim memory resources. If CBool(cnt.State And adStateOpen) Then Set rst = Nothing Set cnt = Nothing cnt.Close End If End Sub

  • Clear UITextField when standard number pad is pressed

    - by Manu
    Hi all, I'm sorry if I didn't explain my problem well enough in the title. In my application, I'm using a small subview to create a very basic calculator on the top side of the screen (I just have an UITextField to show the operations and two buttons). Instead of using a custom keyboard for it, I want to use the standard iPhone number pad. My problem is that after doing an operation (e.g. adding two numbers) and showing the result, I cannot figure out how to clear the screen when the user enters a new number. So, for example: User enters "6" - Number 6 is shown in UITextField User selects "+" - UITextField is cleared to make room for the next number User enters "10" - Number 10 is shown in UITextField User selects "+" - 16 is shown as the result of the previous operation, and should stay there until another number is pressed (he wants to continue adding more numbers) User enters "5" At this point, if I was using a custom keyboard, I could clear the UITextField as soon as the button "5" is pressed by the user, but I cannot figure out how to do so when using the standard number pad. So, the result I get at the moment is "165". Is there a way to detect when a key is pressed in the standard number pad so that I can clear the UITextField before the new number appears? I thought there may be a NSNotification for that, but I couldn't find it. I'm aware that I could solve my problem if I created a custom keyboard or if I used two separated UITextFields (one for the operations and another one for the total), but I would like to use the standard number pad if it's possible. Thanks very much!
