  • My Android ListView item layout looks terrible

    - by jnylen
    I wanted to create a layout like the CyanogenMod call log in that there is a list item and a call button on the left which gets focus separately (screenshot). Instead, I get this mess. Here's my code: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:minHeight="?android:attr/listPreferredItemHeight" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="4dip" > <DontPressWithParentImageView android:id="@+id/play_icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:paddingLeft="14dip" android:paddingRight="14dip" android:layout_alignParentRight="true" android:gravity="center_vertical" android:src="@drawable/sym_play" android:background="@drawable/play_background" /> <View android:id="@+id/divider" android:layout_width="1px" android:layout_height="fill_parent" android:layout_marginTop="5dip" android:layout_marginBottom="5dip" android:layout_toLeftOf="@id/play_icon" android:layout_marginLeft="2dip" android:background="@drawable/divider_vertical_dark" /> <TextView android:id="@+id/file_info" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_marginBottom="8dip" android:layout_marginTop="-10dip" android:layout_marginLeft="10dip" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:textAppearance="?android:attr/textAppearanceSmall" android:textStyle="bold" /> <TextView android:id="@+id/file_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_above="@id/file_info" android:layout_alignWithParentIfMissing="true" android:layout_marginBottom="-10dip" android:layout_marginLeft="4dip" android:textAppearance="?android:attr/textAppearanceLarge" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" /> </RelativeLayout> For reference, the code I started with is here and here, and the source to DontPressWithParentImageView is here (but as you can see from my screenshot, that part is working). What am I doing wrong?

  • Assigning console.log to another object (Webkit issue)

    - by Trevor Burnham
    I wanted to keep my logging statements as short as possible while preventing console from being accessed when it doesn't exist; I came up with the following solution: var _ = {}; if (console) { _.log = console.debug; } else { _.log = function() { } } To me, this seems quite elegant, and it works great in Firefox 3.6 (including preserving the line numbers that make console.debug more useful than console.log). But it doesn't work in Safari 4. [Update: Or in Chrome. So the issue seems to be a difference between Firebug and the Webkit console.] If I follow the above with console.debug('A') _.log('B'); the first statement works fine in both browsers, but the second generates a "TypeError: Type Error" in Safari. Is this just a difference between how Firebug and the Safari Web Developer Tools implement console? If so, it is VERY annoying on Apple's Webkit's part. Binding the console function to a prototype and then instantiating, rather than binding it directly to the object, doesn't help. I could, of course, just call console.debug from an anonymous function assigned to _.log, but then I'd lose my line numbers. Any other ideas?

  • PDCurses TUI C++ Win32 console app - Access violation reading location

    - by Bach
    I have downloaded pdcurses source and was able to successfully include curses.h in my project, linked the pre-compiled library and all good. After few hours of trying out the library, I saw the tuidemo.c in the demos folder, compiled it into an executable and brilliant! exactly what I needed for my project. Now the problem is that it's a C code, and I am working on a C++ project in VS c++ 2008. The files I need are tui.c and tui.h How can I include that C file in my C++ code? I saw few suggestions here but the compiler was not too happy with 100's of warnings and errors. How can I go on including/using that TUI pdcurses includes!? Thanks EDIT: I added extern "C" statement, so my test looks like this now, but I'm getting some other type of error #include <stdio.h> #include <stdlib.h> using namespace std; extern "C" { #include <tui.h> } void sub0(void) { //do nothing } void sub1(void) { //do nothing } int main (int argc, char * const argv[]) { menu MainMenu[] = { { "Asub", sub0, "Go inside first submenu" }, { "Bsub", sub1, "Go inside second submenu" }, { "", (FUNC)0, "" } /* always add this as the last item! */ }; startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); return 0; } Although it is compiling successfully, it is throwing an Error at runtime, which suggests a bad pointer: 0xC0000005: Access violation reading location 0x021c52f9 at line startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); Not sure where to go from here. thanks again.

  • Extra fulltext ordering criteria beyond default relevance

    - by Jeremy Warne
    I'm implementing an ingredient text search, for adding ingredients to a recipe. I've currently got a full text index on the ingredient name, which is stored in a single text field, like so: "Sauce, tomato, lite, Heinz" I've found that because there are a lot of ingredients with very similar names in the database, simply sorting by relevance doesn't work that well a lot of the time. So, I've found myself sorting by a bunch of my own rules of thumb, which probably duplicates a lot of the full-text search algorithm which spits out a numerical relevance. For instance (abridged): ORDER BY [ingredient name is exactly search term], [ingredient name starts with search term], [ingredient name starts with any word from the search and contains all search terms in some order], [ingredient name contains all search terms in some order], ...and so on. Each of these is defined in the SELECT specification as an expression returning either 1 or 0, and so I order by those in sequential order. I would love to hear suggestions for: A better way to define complicated order-by criteria in one place, say perhaps in a view or stored procedure that you can pass just the search term to and get back a set of results without having to worry about how they're ordered? A better tool for this than MySQL's fulltext engine -- perhaps if I was using Sphinx or something [which I've heard of but not used before], would I find some sort of complicated config option designed to solve problems like this? Some google search terms which might turn up discussion on how to order text items within a specific domain like this? I haven't found much that's of use. Thanks for reading!

  • Malloc corrupting already malloc'd memory in C

    - by Kyte
    I'm currently helping a friend debug a program of his, which includes linked lists. His list structure is pretty simple: typedef struct nodo{ int cantUnos; char* numBin; struct nodo* sig; }Nodo; We've got the following code snippet: void insNodo(Nodo** lista, char* auxBin, int auxCantUnos){ printf("*******Insertando\n"); int i; if (*lista) printf("DecInt*%p->%p\n", *lista, (*lista)->sig); Nodo* insert = (Nodo*)malloc(sizeof(Nodo*)); if (*lista) printf("Malloc*%p->%p\n", *lista, (*lista)->sig); insert->cantUnos = auxCantUnos; insert->numBin = (char*)malloc(strlen(auxBin)*sizeof(char)); for(i=0 ; i<strlen(auxBin) ; i++) insert->numBin[i] = auxBin[i]; insert-numBin[i] = '\0'; insert-sig = NULL; Nodo* aux; [etc] (The lines with extra indentation were my addition for debug purposes) This yields me the following: *******Insertando DecInt*00341098->00000000 Malloc*00341098->2832B6EE (*lista)-sig is previously and deliberately set as NULL, which checks out until here, and fixed a potential buffer overflow (he'd forgotten to copy the NULL-terminator in insert-numBin). I can't think of a single reason why'd that happen, nor I've got any idea on what else should I provide as further info. (Compiling on latest stable MinGW under fully-patched Windows 7, friend's using MinGW under Windows XP. On my machine, at least, in only happens when GDB's not attached.) Any ideas? Suggestions? Possible exorcism techniques? (Current hack is copying the sig pointer to a temp variable and restore it after malloc. It breaks anyways. Turns out the 2nd malloc corrupts it too. Interestingly enough, it resets sig to the exact same value as the first one).

  • Localizing DataAnnotations Custom Validation Attribute

    - by Gabe G
    Hello SO, I'm currently working in an MVC 2 app which has to have everything localized in n-languages (currently 2, none of them english btw). I validate my model classes with DataAnnotations but when I wanted to validate a DateTime field found out that the DataTypeAttribute returns always true, no matter it was a valid date or not (that's because when I enter a random string "foo", the IsValid() method checks against "01/01/0001 ", dont know why). Decided to write my own validator extending ValidationAtribute class: public class DateTimeAttribute : ValidationAttribute { public override bool IsValid(object value) { DateTime result; if (value.ToString().Equals("01/01/0001 0:00:00")) { return false; } return DateTime.TryParse(value.ToString(), out result); } } Now it checks OK when is valid and when it's not, but my problem starts when I try to localize it: [Required(ErrorMessageResourceType = typeof(MSG), ErrorMessageResourceName = "INS_DATA_Required")] [CustomValidation.DateTime(ErrorMessageResourceType = typeof(MSG), ErrorMessageResourceName = "INS_DATA_DataType")] public DateTime INS_DATA { get; set; } If I put nothing in the field I get a localized MSG (MSG being my resource class) for the key=INS_DATA_Required but if I put a bad-formatted date I get the "The value 'foo' is not valid for INS_DATA" default message and not the localized MSG. What am I misssing?

  • Can I make a "TCP packet modifier" using tun/tap and raw sockets?

    - by benhoyt
    I have a Linux application that talks TCP, and to help with analysis and statistics, I'd like to modify the data in some of the TCP packets that it sends out. I'd prefer to do this without hacking the Linux TCP stack. The idea I have so far is to make a bridge which acts as a "TCP packet modifier". My idea is to connect to the application via a tun/tap device on one side of the bridge, and to the network card via raw sockets on the other side of the bridge. My concern is that when you open a raw socket it still sends packets up to Linux's TCP stack, and so I couldn't modify them and send them on even if I wanted to. Is this correct? A pseudo-C-code sketch of the bridge looks like: tap_fd = open_tap_device("/dev/net/tun"); raw_fd = open_raw_socket(); for (;;) { select(fds = [tap_fd, raw_fd]); if (FD_ISSET(tap_fd, &fds)) { read_packet(tap_fd); modify_packet_if_needed(); write_packet(raw_fd); } if (FD_ISSET(raw_fd, &fds)) { read_packet(raw_fd); modify_packet_if_needed(); write_packet(tap_fd); } } Does this look possible, or are there other better ways of achieving the same thing? (TCP packet bridging and modification.)

  • XPath expression for a phpBB forum

  • iPhone app doesn't build crash reports

    - by BankStrong
    My app formerly created useful crash logs. I synced my iPhone in the past and found crash logs in library/logs/CrashReporter About a month ago, my app stopped creating crash reports. When I first discovered this problem, I assumed it was due to memory corruption (a possibility in my app). I just created a new project and added a crash to it. // Implement viewDidLoad to do additional setup after loading the view, // typically from a nib. - (void)viewDidLoad { NSMutableArray *array = [[NSMutableArray alloc] init]; [array removeObjectAtIndex:-1]; [super viewDidLoad]; } This app does not create a crash report either. Ideas I've started to explore: My phone is corrupted (tried restoring - somehow I brought it to the state from a few months ago) My XCode is corrupt (tried reinstalling, but current download demands Snow Leopard - and I can't upgrade to Snow Leopard online). This seems possible - I may have messed with device support around a month ago (similar to http://stackoverflow.com/questions/1224867/does-iphone-os-3-0-1-ruin-your-development-phone ) The location for crash logs has somehow moved. Suggestions?

  • Updating multiple related tables in SQLite

    - by PerryJ
    Just some background, sorry so long winded. I'm using the System.Data.SQLite ADO.net adapter to create a local sqlite database and this will be the only process hitting the database, so I don't need to worry about concurrency. I'm building the database from various sources and don't want to build this all in memory using datasets or dataadapters or anything like that. I want to do this using SQL (DdCommands). I'm not very good with SQL and complete noob in sqlite. I'm basically using sqlite as a local database / save file structure. The database has a lot of related tables and the data has nothing to do with People or Regions or Districts, but to use a simple analogy, imagine: Region table with auto increment RegionID, RegionName column and various optional columns. District table with auto increment DistrictID, DistrictName, RegionId, and various optional columns Person table with auto increment PersonID, PersonName, DistrictID, and various optional columns So I get some data representing RegionName, DistrictName,PersonName, and other Person related data. The Region, District and/or Person may or may not be created at this point. Once again, not being the greatest with this, my thoughts would be something like: Check to see if Region exists and if so get the RegionID else create it and get RegionID Check to see if District exists and if so get the DistrictID else create it adding in RegionID from above and get DistrictID Check to see if Person exists and if so get the PersonID else create it adding in DistrictID from above and get PersonID Update Person with rest of data. In MS SQL Server I would create a stored procedure to handle all this. Only way I can see to do this with sqlite is a lot of commands. So I'm sure I'm not getting this. I've spent hours looking around on various sites but just don't feel like I'm going down the right road. Any suggestions would be greatly appreciated.

  • Excel 2007 file writer in C# results in a corrupt file

    - by Martin
    Hi, I am using a BinaryReader to read an Excel 2007 file from an Exchange mailbox using a OWA, the file is then written to disk using a BinaryWriter. My problem is that the two files don't match when the writer finishes. Worse still Excel 2007 won't open the writen file. Previously Excel 2003 has had no problem with the solution below. And Excel 2007 doesn't have an issue if the file is an Excel 2003 format file, only if the file format is Excel 2007 (*.xlsx). BinaryReader: using(System.IO.Stream stream = resource.GetInputStream(attachedFiles[k].Address)) { using(System.IO.BinaryReader br = new System.IO.BinaryReader(stream)) { attachment.Data = new byte[attachedFiles[k].Size]; int bufPosn=0, len=0; while ((len = br.Read( attachment.Data, bufPosn, attachment.Data.Length-bufPosn )) > 0) { bufPosn += len; } br.Close(); } } BinaryWriter: FileStream fs = new FileStream(fileName, FileMode.Create); BinaryWriter binWriter = new BinaryWriter(fs); binWriter.Write( content, 0, content.Length ); binWriter.Close(); fs.Close(); Suggestions gratfully received.

  • Wordpress displays posts of category ID

    - by Miker
    Can't seem to find the right answer for what I thought would be trivial. I have some categories arranged like this... Parent Category 1 - Child Category 1 - Child Category 2 - Child Category 3 ...and I have some posts that are in Child Category 2. I want my page to display all posts from the category I am currently in. This is what I am doing right now: <?php query_posts('cat=2&showposts=10'); if (have_posts()) : while (have_posts()) : the_post(); ?> <div class="timeline"> <h3><?php the_title(); ?></h3> <?php the_content();?> <?php endwhile; else: ?> <?php _e('No Posts Sorry.'); ?> <?php endif; ?> </div> As you can see I am having to manually specify the category (cat=2), but instead I want it to automatically detect the category I am already in and display the posts (that way if I'm in a different category it will display those posts). Any suggestions? Thanks in advance. (SO Community = Awesome Sauce).

  • SQL Joining on a one-to-many relationship

    - by Harley
    Ok, here was my original question; Table one contains ID|Name 1 Mary 2 John Table two contains ID|Color 1 Red 1 Blue 2 Blue 2 Green 2 Black I want to end up with is ID|Name|Red|Blue|Green|Black 1 Mary Y Y 2 John Y Y Y It seems that because there are 11 unique values for color and 1000's upon 1000's of records in table one that there is no 'good' way to do this. So, two other questions. Is there an efficient way to query to get this result? I can then create a crosstab in my application to get the desired result. ID|Name|Color 1 Mary Red 1 Mary Blue 2 John Blue 2 John Green 2 John Black If I wanted to limit the number of records returned how could I do a query to do something like this? Where ((color='blue') AND (color<>'red' OR color<>'green')) So using the above example I would then get back ID|Name|Color 1 Mary Blue 2 John Blue 2 John Black I connect to Visual FoxPro tables via ADODB to use SQL. Thanks!

  • Oracle rownum in db2 - Java data archiving

    - by HonorGod
    I have a data archiving process in java that moves data between db2 and sybase. FYI - This is not done through any import/export process because there are several conditions on each table that are available on run-time and so this process is developed in java. Right now I have single DatabaseReader and DatabaseWriter defined for each source and destination combination so that data is moved in multiple threads. I guess I wanted to expand this further where I can have Multiple DatabaseReaders and Multiple DatabaseWriters defined for each source and destination combination. So, for example if the source data is about 100 rows and I defined 10 readers and 10 writer, each reader will read 10 rows and give them to the writer. I hope process will give me extreme performance depending on the resources available on the server [CPU, Memory etc]. But I guess the problem is these source tables do not have primary keys and it is extremely difficult to grab rows in multiple sets. Oracle provides rownum concept and i guess the life is much simpler there....but how about db2? How can I achieve this behavior with db2? Is there a way to say fetch first 10 records and then fetch next 10 records and so on? Any suggestions / ideas ? Db2 Version - DB2 v8.1.0.144 Fix Pack Num - 16 Linux

  • Django 1.4.1 error loading MySQLdb module when attempting 'python manage.py shell'

Getting the output below: rrdhcp-10-32-44-126:django pavelfage$ python manage.py shell Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line utility.execute() File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 382, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/base.py", line 196, in run_from_argv self.execute(*args, **options.__dict__) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/base.py", line 232, in execute output = self.handle(*args, **options) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/base.py", line 371, in handle return self.handle_noargs(**options) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/commands/shell.py", line 45, in handle_noargs from django.db.models.loading import get_models File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/__init__.py", line 40, in <module> backend = load_backend(connection.settings_dict['ENGINE']) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/__init__.py", line 34, in __getattr__ return getattr(connections[DEFAULT_DB_ALIAS], item) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/utils.py", line 92, in __getitem__ backend = load_backend(db['ENGINE']) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/utils.py", line 24, in load_backend return import_module('.base', backend_name) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/backends/mysql/base.py", line 16, in <module> raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named _mysql Any suggestions really appreciated.

  • Where can I find free and open data?

    - by kitsune
    Sooner or later, coders will feel the need to have access to "open data" in one of their projects, from knowing a city's zip to a more obscure information such as the axial tilt of Pluto. I know data.un.org which offers access to the UN's extensive array of databases that deal with human development and other socio-economic issues. The other usual suspects are NASA and the USGS for planetary data. There's an article at readwriteweb with more links. infochimps.org seems to stand out. Personally, I need to find historic commodity prices, stock values and other financial data. All these data sets seem to cost money however. Clarification To clarify, I'm interested in all kinds of open data, because sooner or later, I know I will be in a situation where I could need it. I will try to edit this answer and include the suggestions in a structured manners. A link for financial data was hidden in that readwriteweb article, doh! It's called opentick.com. Looks good so far! Update I stumbled over semantic data in another question of mine on here. There is opencyc ('the world's largest and most complete general knowledge base and commonsense reasoning engine'). A project called UMBEL provides a light-weight, distilled version of opencyc. Umbel has semantic data in rdf/owl/skos n3 syntax. The Worldbank also released a very nice API. It offers data from the last 50 years for about 200 countries

  • ASPX FormsAuthentication.RedirectFromLoginPage function is not working anymore

    - by Mike Webb
    Here is my issue. I have an ASPX web site and I have code in there to redirect from the login page with the call to "FormsAuthentication.RedirectFromLoginPage(username, false);" This sends the user from the root website folder to 'website/Admin/'. I have a 'default.aspx' page in 'website/Admin/' and the call to redirect works on a previous version of the website we have running currently, but the one that I am updating on a separate test server is not working. It gives me the error "Directory Listing Denied. This Virtual Directory does not allow contents to be listed." I have this in the config file: <authorization> <allow users="*" /> </authorization> under the "authentication" option and... <location path="Admin"> <system.web> <authorization> <deny users="?" /> </authorization> </system.web> </location> for the location of Admin. Also, there is no difference in the code between the web.config, Login.aspx, or the default.aspx files on the current server and the one on the test server, so I am confused as to why the redirect will not work on both. It even works in the Visual Studio server environment, for which the code is also identical. Any suggestions and help is appreciated.

  • Detect click on URL in RichEdit

    - by Tofig Hasanov
    I am trying to update RichEdit so that it detects URL and enables clicking on it to open in the browser. Detecting URL is easy, I just use the following code from http://www.scalabium.com/faq/dct0146.htm mask := SendMessage(MNote.Handle, EM_GETEVENTMASK, 0, 0); SendMessage(MNote.Handle, EM_SETEVENTMASK, 0, mask or ENM_LINK); SendMessage(MNote.Handle, EM_AUTOURLDETECT, Integer(True), 0); but the second part doesn't work for me. They give the following code to capture EN_LINK message and processing it: type TForm1 = class(TForm) protected procedure WndProc(var Message: TMessage); override; end; ... procedure TForm1.WndProc(var Message: TMessage); var p: TENLink; strURL: string; begin if (Message.Msg = WM_NOTIFY) then begin if (PNMHDR(Message.LParam).code = EN_LINK) then begin p := TENLink(Pointer(TWMNotify(Message).NMHdr)^); if (p.msg = WM_LBUTTONDOWN) then begin SendMessage(RichEdit1.Handle, EM_EXSETSEL, 0, LongInt(@(p.chrg))); strURL := RichEdit1.SelText; ShellExecute(Handle, 'open', PChar(strURL), 0, 0, SW_SHOWNORMAL); end end end; inherited; end; When I run the program, URL is detected, but clicking on it doesn't do anything. Using debug I found out that Message.Msg = WM_NOTIFY is not true when I click on URL. I then tried to override TRichEdit's WndProc, but result is the same. Any suggestions?

  • Invalid security validation exception inside a SharePoint workflow

    - by Dan Revell
    I'm having a strange security problem with a SharePoint workflow. Particular calls seem to result in the following exception: Microsoft.SharePoint.SPException: The security validation for this page is invalid. I've come across this error before and the simple fix is web.AllowUnsafeUpdates = true; ... web.AllowUnsafeUpdates = false; However I've never once encountered this problem inside a workflow before since a workflow runs as system. I first got this error in a code activity where I set the value of a column on the list item. Wrapping the item.Update in AllowUnsafeUpdates fixed it. After the code activity I have a CreateTask activity. This also causes the same error but only after running the code inside the activity's MethodInvoking. In both cases there's a SPListItem.UpdateItem involved within the stack trace. This call is failing a security check. I don't know anything about how this check works so I don't know where to look next. This is a strange one, because this SharePoint dev machine has been working fine for some time. No other projects or workflows exhibit this behaviour so that rules out an installation problem. There's just something about this particular workflow. [UPDATE] I've gotten around the issue by just creating a new project and building it up again. I still have the broken one and I'd still like to figure out the problem with it. I'd appreciate any suggestions of what it might be.

  • IIS 7.5 refuses to load 64-bit assembly - possible CAS problem?

    - by Rune
    Hi, I just downloaded the Orchard CMS, opened it up in VS2008 and hit F5: Everything runs fine. I then created a website in IIS 7.5 and pointed it to the web project's directory and set up permissions correctly (I hope). I downloaded the 64-bit version System.Data.SQLite as suggested here: Orchard Work Item 14798 and here: SO: Could not load file or assembly 'System.Data.SQLite'. The site runs in Full Trust. When I point my browser to the site running through IIS I get Could not load file or assembly 'System.Data.SQLite, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. Failed to grant minimum permission requests. I don't know much about Code Access Security (if that is even what's at play here), so I am at a loss here. What am I doing wrong / not understanding / not seeing? How do I provide appropriate permissions and to whom / what? Is there any hope of ever deploying this application to a hoster where I am only allowed to run in Medium Trust? Any help, pointers or suggestions would be greatly appreciated. Thanks. NOTE: the question is not why this initially worked when run through Cassini. The answer to that question is contained in the answer to the SO question referenced above.

  • Accounting System for Winforms / SQL Server applications

    - by Craig L
    If you were going to write a vertical market C# / WinForms / SQL Server application and needed an accounting "engine" for it, what software package would you chose ? By vertical market, I mean the application is intended to solve a particular set of business problems, not be a generic accounting application. Thus the value add of the program is the 70% of non-accounting related functionality present in the finished product. The 30% of accounting functionality is merely to enable the basic accounting needs of the business. I said all that to lead up to this: The accounting engine needs to be a royalty-free runtime license and not super expensive. I've found a couple C#/SQL Server accounting apps that can be had with source code and a royalty free run time for $150k+ and that would be fine for greenfield development funded by a large bankroll, but for smaller apps, that sort of capital outlay isn't feasible. Something along the lines of $5k to $15k for a royalty-free runtime would be more reasonable. Open-source would be even better. By accounting engine, I mean something that takes care of at a minimum: General Ledger Invoices Statements Accounts Receivable Payments / Credits Basically, an accounting engine should be something that lets the developer concentrate on the value added (industry specific business best practices / processes) part of the solution and not have to worry about how to implement the low level details of a double entry accounting system. Ideally, the accounting engine would be something that is licensed on a royalty free run-time basis. Suggestions, please ?

  • Trying to build a Drupal-like CMS in ASP.NET MVC - Newbie Questions

    - by user252160
    I am new to ASP.NET MVC, and the ASP.NET technology in general, so, please, excuse the stupidity of my questions. I have a lot of experience with php development and CMS customization (Drupal and Wordpress mainly), and I wanted to know whether some techniques could be applied in asp.net mvc. I want to know what exactly could be modified without recompiling an already built application Can I edit the views without recompiling the app. Can I create custom themes ? Can I add plugins compiled as dlls and use them at runtime. Can I "mark" the assembly in such a way that the web application will check on the next request and will reference it, without me manually adding it to the project and recompiling. I've heard that this is possible. I will make sure to add more when something comes up. The reason I am asking is because I'd like to try and develop a Drupal-like CMS (custom types, views, etc) in asp.net mvc. The dynamism of php will be quite a challenge to replicate in a compiled technology, yet I am ready to try.
