  • How to marshal the type of "Cstring" in .NET Compact Framework(C#)?

    - by SmartJJ
    How to marshal the type of "Cstring" in .NET Compact Framework(C#)? DLLname:Test_Cstring.dll(OS is WinCE 5.0),source code: extern "C" __declspec(dllexport) int GetStringLen(CString str) { return str.GetLength(); } I marshal that in .NET Compact Framework(C#),for example: [DllImport("Test_Cstring.dll", EntryPoint = "GetStringLen", SetLastError = true)] public extern static int GetStringLen(string s); private void Test_Cstring() { int len=-1; len=GetStringLen("abcd"); MessageBox.Show("Length:"+len.ToString()); //result is -1,so PInvoke is unsuccessful! } The Method of "GetStringLen" in .NET CF is unsuccessful! How to marshal this type of "Cstring"? Any information about it would be very appreciated!

  • Serialized form fields in Ruby on Rails problem

    - by Violet
    I'm having a problem making serialized columns in my model persist correctly in forms. If my model validation fails I want to redisplay the "new" page with all my model data still in the forms. Right now, everything except the serialized fields seem to persist (if my Order fails to purchase, on the "new" page the email is still filled in but the shipping address fields are not). Is this a Rails bug or am I doing something wrong? My model: class Order < ActiveRecord::Base serialize :shipping_address end My controller: def new @order = Order.new end def create @order = Order.new params[:order] if @order.purchase then render :action => "success" else render :action => "new" end end My view, new.html.haml: = form_for @order do |f| - if @order.errors.any? #errorExplanation %p The following errors occurred: %ul - for msg in @order.errors.full_messages %li= msg %h2 Billing Information = f.label :email = f.text_field :email %h2 Shipping Address = f.fields_for :shipping_address do |b| %p.field.address = b.label :address1 = b.text_field :address1 %p= f.submit "Place Order"

  • How can I match at the beginning of any line, including the first, with a Perl regex?

    - by JoelFan
    According the the Perl documentation on regexes: By default, the "^" character is guaranteed to match only the beginning of the string ... Embedded newlines will not be matched by "^" ... You may, however, wish to treat a string as a multi-line buffer, such that the "^" will match after any newline within the string ... you can do this by using the /m modifier on the pattern match operator. The "after any newline" part means that it will only match at the beginning of the 2nd and subsequent lines. What if I want to match at the beginning of any line (1st, 2nd, etc.)? EDIT: OK, it seems that the file has BOM information (3 chars) at the beginning and that's what's messing me up. Any way to get ^ to match anyway? EDIT: So in the end it works (as long as there's no BOM), but now it seems that the Perl documentation is wrong, since it says "after any newline"

  • App crashes when adding array data to table cells

    - by bassmandan
    I am trying to create a table view that loads a number of tweets into the table (one per cell etc). I am using NSXMLParser to get the information and have got as far as creating an array with the selection of tweets that I want. However, when I try to add them to the table cells, the app crashes on the line: cell.textLabel.text = cellValue; An NSLog before this shows in the console that the app is getting the correct data, so I am a bit stumped as to why this isn't working. This is the block of code that appears to be having the problem: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } // Set up the cell... NSString *cellValue = [statuses objectAtIndex:indexPath.row]; NSLog(@"%@", cellValue); cell.textLabel.text = cellValue; return cell;} If it makes a difference, I am using ARC and the latest version of XCode. I'm still quite new to all this, so if I need to give some extra information, let me know. Thanks in advance.

  • MSSQL 2000 Stored Procedure to Split Shift Times

    - by JClaspill
    I am being asked to alter a system to include the ability to have pay differentials based on hours worked. The old method included a stored procedure (MSSQL2000 db) that did the basics, but simply knows the start and end of every shift. So, this is the information I start with: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 8.643055 | 2011-01-08 07:57:35.557 | 2011-01-08 16:36:10.120 And I need to turn that into something like: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 4.00 | 2011-01-08 08:00:00.000 | 2011-01-08 12:00:00.000 Dave | ShiftDiff1 | 4.50 | 2011-01-08 12:00:00.000 | 2011-01-08 16:30:00.000 The ShiftDiff's range from hours to certain days, to a combo of both. Should I try to make the SQL2000 SP do this or pass the info back to my ASP.NET(C#) app and let it handle it, then send back?

  • UI suggestions on how to display suggested tags for a given text to a user?

    - by Danny
    I am writing a web-app that uses a tagging system to organize the user's submitted reports. Part of it uses ajax to get suggestions for tags to present to the user based on the content of their report. I am looking for suggestions on how to present this information for the user. I'm not quite certain what a friendly way to do this would be. Edit: Well, most of the responses here seem to be focused on the user typing in keywords. The idea I'm trying to define here is more towards presenting the user a set of suggested keywords that they may accept or decline without having to type a tag in manually. (That option is of course still available to them) --------------------------- # say they can checkoff or select tags they like. | o[tag2] x[foo] o[moo] | | x[tag1] o[bar] | ---------------------------

  • Return order of MySQL SHOW COLUMNS

    Hey guys. Simple one this, but one I can't seem to find any information on so here goes. I need to find the columns in a specific table, which is no problem.... SHOW COLUMNS FROM tablename LIKE '%ColumnPrefix%'; But I need to know what order they will be returned, preferable by choosing to order the results ascending alphabetically. I have had no luck with using ORDER BY Field. Any ideas? Cheers!

  • P2 Touchpoint chmod not working?

    - by Michael
    I'm using Eclipse 3.5.2 and I've created a p2.inf with the following information: instructions.install = \ chmod(targetDir:@artifact,targetFile:$os$/libfoo.so,permissions:755); instructions.install.import= \ org.eclipse.equinox.p2.touchpoint.natives.chmod I placed the p2.inf inside the META-INF folder of the fragment, but when I install the update site, libfoo.so does not have execute permissions. After pulling my hair out, I tried a p2.inf referencing a non-existing *.so, but nothing seems to happen. No error messages, exceptions, or warnings of any kind to indicate the P2 touchpoint action failed... What's the deal? Any ideas?

  • How to handle similar items in rails MVC?

    - by mocker
    I'm working on building a pretty simple site mainly as an exercise in learning more about rails. You can see my rough progress at statific.com. It's working pretty much as I wanted it for keeping track of server information, but now I'd like to expand it to other things, next on the list being firewalls. I can pretty easily duplicate all the models, views, etc.. that I have for my servers. The problem I see with that is that it isn't very DRY since most of the code would look the same, the only difference would be the attributes I have setup for firewalls would be different than for servers. I know in plain ruby this is pretty simple, you can have a 'Product' w/ common attributes ('manufacturer', 'model') and then have children with more specific attributes. Does the same type of concept exist for rails, or am I just over thinking this?

  • C# Assembly Xna.Framework.dll does not load

    - by jbsnorro
    When trying to load Microsoft.Xna.Framework.dll from any project, it throws a FileNotFoundException. The specified module could not be found. (Exception from HRESULT: 0x8007007E), with no innerException. Even the simple code like the following throws that exception: static void Main(string[] args) { Assembly.LoadFile(@"C:\Microsoft.Xna.Framework.dll"); } I run XP x64, but I've set the platform in the configuration manager to x86, because I know it shouldn't(doesn't) work on x64 or Any CPU. I've manually added the dll file to GAC, but that didn't solve the problem. I have also tried the M$ Assembly Binding Log Viewer to see if those logs had any useful information, but they didn't. Everything, the loading etc, was a success according to them. Any suggestions? please?

  • calling a function without knowing the number of parameters in advance

    - by Sourabh Bose
    suppose i have a dll with 2 functions.name of dll="dll1" f1(int a, int b, int c); f2(int a); my program would take the funtion name ,the dll name and a "list" of parameters as input. how would i call the appropriate function with its appropriate parameters. i.e, if input is dll1 f1 list(5,8,9) this would require me to call f1 with 3 parameters if input was dll1 f2 list(8) it would require me to call f2 with one parameter how would i call the function without knowing the number of parameters in advance. further clarification: how do I write code that will call any function with all its arguments by building the argument list dynamically using some other source of information

  • Create Out-Of-Process COM in C#/.Net ?

    - by Huck
    Hi, I need to create an out-of-process COM server (.exe) in C# that will be accessed by multiple other processes on the same box. The component has to be a single process because it will cache the information it provides to its consumers in memory. Note: the processes that will access my COM Server are mostly Matlab processes, thus the necessity for a COM interface. I have seen threads regarding creating in-process COM components in .Net on stack overflow (Create COM ...) and on the web, but am having a hard time to find a way to create out-of-process components with .Net. How is this achievable? Any suggested references? Thanks.

  • Do a database query on Textbox onblur event

    - by user279521
    I am using asp.net 3.5 with C#. I need to do a database lookup when a user enters ProductID in txtProductID. I guess doing javascript is out of the question since this will have to be server side call. I wrote this code in the page_load event of the webpage: protected void Page_Load(object sender, EventArgs e) { txtProductID.Attributes.Add("onblur", "LookupProduct()"); } protected void LookupUser() { //Lookup Product information on onBlur event; } I get an error message: Microsoft JScript runtime error: Object expected How can I resolve this ?

  • Caching roles in a cookie

    - by AspOnMyNet
    1) a) I assume roles are cached ( by setting Roles.CacheRolesInCookie ) only for current user? b) Besides Roles.GetRolesForUser(_currentUser), are there any other methods that will read role information for current user from role cookie and thus won’t have to connect to the data base? 2) a) I assume that normally role cookie gets updated only when current user is added or removed from the role(s) or when the cookie expires? b) Because role names can be cached apart from the data source, it is possible that changes to role management at the data source would not be reflected in the cached values. In this case, the user must close and re-open their browser to clear the cached cookie value. How exactly could role cookie get cached apart from the data source? 3) If the number of roles cached in a role cookie equals the value of Roles.MaxCachedResults, then I assume when Roles.GetRolesForUser (_currentuser) gets called, it will need to check the DB to see whether user is also a member of any additional roles? thanx

  • Windows 7: Loop through Taskbar items

    - by balint
    Hi, I'm trying to build a small utility for myself only to hide labels of running programs with windows visible in the taskbar where the label holds no information (for example "iTunes", "Microsoft SQL Server Mngmt Studio", "~cmd.exe") but keep windows like Windows Explorer and Visual Studio and MSN ungroupped, with labels (to know which folders you are currently listing, which projects are open, and who are you chatting with by name). I'm trying to loop through all windows in the taskbar on windows 7, but without any luck. I found some samples for XP's taskbar reorders, they no longer usable. I've checked the samples in WindowsAPICodePack for Windows 7 Taskbar manipulation, but it only lets me access my processes' windows.

  • Save in Sessions to reduce database load

    - by Kovu
    at the moment I try to reduce the load on my database extremly, so I had a look in my website and think about - what database calls can I try to avoid. So is there a rule for that? Sould I save every information in a Session that is nearly never changed? e.g.: The User-Table is a 35-coloumn-table which I need so often in so different ways, that in the moment I got this user-object at nearly every PageLoad AND in the master-site-page-load (Settings, display the username for a welcome message, colors etc etc.). So is that good to avoid the database query here, save the User-Object in a Session and call it from the session - and of course destroy the session whereever the User-Object get changed (e.g. User change his settings)?

  • Find user defined functions and their usage in a massive code base

    - by Frenck
    Hi, I'm currently working with an massive PHP codebase, witch is completely undocumented. Here's the deal. All of the PHP code is included every page call. They build a simple include all kinda function that scan's the directory and includes all PHP files it can find. It works recursively for all the subfolders. I would like to know what functions are used in what files and from which files those functions came. I need to know this in order to switch to normale includes. Also it gives me more information about not used functions and files (since it a really old and big codebase, there is a lot of legacy in it). It there a tool or something for PHP that can check this kind of stuff in a codebase?

  • How to deny payment via PayPal IPN?

    - by Nick
    Hello all, I need to create dynamic 'Pay Now' buttons on my site, and PayPal says the way to do this is via an HTML FORM with preset variables for the price, currency, and item of the purchase. I use PayPal IPN to notify me when a payment has complete. However, what's to stop someone from modifying the query parameters of the Pay Now button to change the price? Some people have told me to redirect the button through a PHP file that sends you to a PayPal payment page with the parameters in place, but the price could just as easily be manipulated in the Web browser's address bar. My question is, how can I deny a payment if the information I receive from PayPal's IPN service is invalid (if the price doesn't match our records)? I'm quite confused and couldn't find any documentation on what I'm looking for. Hopefully, you guys can help. Thanks!

  • Determining a location's side of the road position with MapKit

    - by idStar
    Is there a way to use MapKit in iOS7 to not only get geocoding for an address, but determine what side of the road it is on? I'm not trying to build a full function navigation app, but similar to navigation apps that tell you things like "Your destination is in 100 feet on the right", I'd like to be able to obtain this information. Does MapKit give one a way to do this? Do I need to adopt routing privileges to access such, or is this just not available in the SDK period? If not available in the iOS7 SDK, knowing what options exist as services, would be a helpful pointer.

  • Is there any sense in performing binary AND with a number where all bits are set to 1

    - by n535
    Greetings everybody. I have seen examples of such operations for so many times that I begin to think that I am getting something wrong with binary arithmetic. Is there any sense to perform the following: byte value = someAnotherByteValue & 0xFF; I don't really understand this, because it does not change anything anyway. Thanks for help. P.S. I was trying to search for information both elsewhere and here, but unsuccessfully. EDIT: Well, off course i assume that someAnotherByteValue is 8 bits long, the problem is that i don't get why so many people ( i mean professionals ) use such things in their code. For example in Jon Skeet's MiscUtil there is: uint s1 = (uint)(initial & 0xffff); where initial is int.

  • MediaElement seems to disable lock screen when playing a video

    - by CrossProduct
    I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

  • Exception Class: When to Derive from it, In C# (.Net)?

    - by IbrarMumtaz
    I am continuing with my exam revision. I have come across the usage of the Base Exception class and I have seen it on exam papers also. My question is when do you derive from the Base Exception class? I am of the impression if you want a custom class to throw an exception with more meaningful information, then you can create a custom exception class that contains the exact data that is representative of how your custom class is used and what scenario it is designed to be used for? Why can't my custom exception class derive from 'ApplicationException' or 'SecurityException' or the base 'Exception' class? I am of the impression that I should derive from the base Exception class and not the previous two. My question second is, when would you derive from the other two??? Are there any clear-cut distinctions as to when you would derive from either one of these three? Assuming there are no others I have I have missed out? Thanks, Ibrar

  • Search a variable for an address

    - by chrissygormley
    Hello, I am trying to match information stored in a variable. I have a list of uuid's and ip addresses beside them.

So far I have just tried to get it to match the string to no avail. Can anyone point out a solution to this. Thanks

  • Linux Kernel - Slab Allocator Question

    - by Drex
    I am playing around with the kernel and am looking at the kmem_cache files_cachep belonging to fork.c. It detects the sizeof(files_struct). My question is this: I have altered files_struct and added a rb_root (red/black tree root) using the built-in functionality in linux/rbtree.h. I can properly insert values into this tree. However, at some point, a segfault occurs and GDB backtraces the following information: (gdb) backtrace 0 0x08066ad7 in page_ok (page=) at arch/um/os-Linux/sys-i386/task_size.c:31 1 0x08066bdf in os_get_top_address () at arch/um/os-Linux/sys-i386/task_size.c:100 2 0x0804a216 in linux_main (argc=1, argv=0xbfb05f14) at arch/um/kernel/um_arch.c:277 3 0x0804acdc in main (argc=1, argv=0xbfb05f14, envp=0xbfb05f1c) at arch/um/os-Linux/main.c:150 I have spent many hours trying to figure out why there is a segfault given that the red/black tree inserts properly. I'm thinking it's a memory allocation issue with new processes made by fork() of a parent process. Could this be the case and could it have something to do with kmem_cache files_cachep?
