• Windows Forms: Unable to Click to Focus a MaskedTextBox in a Non TopLevel Form

  - by Overhed

  Like the title says, I've got a Child form being shown with it's TopLevel property set to False and I am unable to click a MaskedTextBox control that it contains (in order to bring focus to it). I can bring focus to it by using TAB on the keyboard though. The child form contains other regular TextBox controls and these I can click to focus with no problems, although they also exhibit some odd behavior: for example if I've got a value in the Textbox and I try to drag-click from the end of the string to the beginning, nothing happens. In fact I can't use my mouse to move the cursor inside the TextBox's text at all (although they keyboard arrow keys work). I'm not too worried about the odd TextBox behavior, but why can't I activate my MaskedTextBox by clicking on it? Below is the code that shows the form: Dim newReportForm As New Form Dim formName As String Dim FullTypeName As String Dim FormInstanceType As Type formName = TreeView1.SelectedNode.Name FullTypeName = Application.ProductName & "." & formName FormInstanceType = Type.GetType(FullTypeName, True, True) newReportForm = CType(Activator.CreateInstance(FormInstanceType), Form) Try newReportForm.Top = CType(SplitContainer1.Panel2.Controls(0), Form).Top + 25 newReportForm.Left = CType(SplitContainer1.Panel2.Controls(0), Form).Left + 25 Catch End Try newReportForm.TopLevel = False newReportForm.Parent = SplitContainer1.Panel2 newReportForm.BringToFront() newReportForm.Show()

• Python: puzzling behaviour inside httplib

  - by Anna

  I have added one line ( import pdb; pdb.set_trace() ) to httplib's HTTPConnection.putheader, so I can see what's going on inside. httplib.py, line 489: def putheader(self, header, value): """Send a request header line to the server. For example: h.putheader('Accept', 'text/html') """ import pdb; pdb.set_trace() if self.__state != _CS_REQ_STARTED: raise CannotSendHeader() str = '%s: %s' % (header, value) self._output(str) then ran this from the interpreter import urllib2 urllib2.urlopen('http://www.ioerror.us/ip/headers') ... and as expected PDB kicks in: > c:\python26\lib\httplib.py(858)putheader() -> if self.__state != _CS_REQ_STARTED: (Pdb) in PDB I have the luxury of evaluating expressions on the fly, so I have tried to enter self.__state: (Pdb) self.__state *** AttributeError: HTTPConnection instance has no attribute '__state' Alas, there is no __state of this instance. However when I enter step, the debugger gets past the if self.__state != _CS_REQ_STARTED: line without a problem. Why is this happening? If the self.__state doesn't exist python would have to raise an exception as it did when I entered the expression. Python version: 2.6.4 on win32

• Extending EF4 SQL Generation

  - by Basiclife

  Hi, We're using EF4 in a fairly large system and occasionally run into problems due to EF4 being unable to convert certain expressions into SQL. At present, we either need to do some fancy footwork (DB/Code) or just accept the performance hit and allow the query to be executed in-memory. Needless to say neither of these is ideal and the hacks we've sometimes had to use reduce readability / maintainability. What we would ideally like is a way to extend the SQL generation capabilities of the EF4 SQL provider. Obviously there are some things like .Net method calls which will always have to be client-side but some functionality like date comparisons (eg Group by weeks in Linq to Entities ) should be do-able. I've Googled but perhaps I'm using the wrong terminology as all I get is information about the new features of EF4 SQL Generation. For such a flexible and extensible framework, I'd be surprised if this isn't possible. In my head, I'm imagining inheriting from the [SQL 2008] provider and extending it to handle additional expressions / similar in the expression tree it's given to convert to SQL. Any help/pointers appreciated. We're using VS2010 Ultimate, .Net 4 (non-client profile) and EF4. The app is in ASP.Net and is running in a 64-Bit environment in case it makes a difference.

• TCP: Address already in use exception - possible causes for client port? NO PORT EXHAUSTION

  - by TomTom

  Hello, stupid problem. I get those from a client connecting to a server. Sadly, the setup is complicated making debugging complex - and we run out of options. The environment: *Client/Server system, both running on the same machine. The client is actually a service doing some database manipulation at specific times. * The cnonection comes from C# going through OleDb to an EasySoft JDBC driver to a custom written JDBC server that then hosts logic in C++. Yeah, compelx - but the third party supplier decided to expose the extension mechanisms for their server through a JDBC interface. Not a lot can be done here ;) The Symptom: At (ir)regular intervals we get a "Address already in use: connect" told from the JDBC driver. They seem to come from one particular service we run. Now, I did read all the stuff about port exhaustion. This is why we have a little tool running now that counts ports and their states every minute. Last time this happened, we had an astonishing 370 ports in use, with the count rising to about 900 AFTER the error. We aleady patched the registry (it is a windows machine) to allow more than the 5000 client ports standard, but even then, we are far far from that limit to start with. Which is why I am asking here. Ayneone an ide what ELSE could cause this? It is a Windows 2003 Server machine, 64 bit. The only other thing I can see that may cause it (but this functionality is supposedly disabled) is Symantec Endpoint Protection that is installed on the server - and being capable of actinc as a firewall, it could possibly intercept network traffic. I dont want to open a can of worms by pointing to Symantec prematurely (if pointing to Symantec can ever be seen as such). So, anyone an idea what else may be the cause? Thanks

• Using TaskDialogIndirect in C#

  - by Dennis Delimarsky

  I've been working for a while with the regular Windows Vista/7 TaskDialog for a while, and I wanted to add some additional functionality (like custom buttons and a footer), so I need to use TaskDialogIndirect. Following the MSDN documentation for TaskDialogIndirect, I got this signature: [DllImport("comctl32.dll",CharSet = CharSet.Unicode,EntryPoint="TaskDialogIndirect")] static extern int TaskDialogIndirect (TASKDIALOGCONFIG pTaskConfig, out int pnButton, out int pnRadioButton, out bool pfVerificationFlagChecked); The TASKDIALOGCONFIG class is shown below: public class TASKDIALOGCONFIG { public UInt16 cbSize; public IntPtr hwndParent; public IntPtr hInstance; public String dwFlags; public String dwCommonButtons; public IntPtr hMainIcon; public String pszMainIcon; public String pszMainInstruction; public String pszContent; public UInt16 cButtons; public TASKDIALOG_BUTTON pButtons; public int nDefaultButton; public UInt16 cRadioButtons; public TASKDIALOG_BUTTON pRadioButtons; public int nDefaultRadioButton; public String pszVerificationText; public String pszExpandedInformation; public String pszExpandedControlText; public String pszCollapsedControlText; public IntPtr hFooterIcon; public IntPtr pszFooterText; public String pszFooter; // pfCallback; // lpCallbackData; public UInt16 cxWidth; } The TASKDIALOG_BUTTON implementation: public class TASKDIALOG_BUTTON { public int nButtonID; public String pszButtonText; } I am not entirely sure if I am on the right track here. Did anyone use TaskDialogIndirect from managed code directly through WinAPI (without VistaBridge or Windows API Code Pack)? I am curious about the possible implementations, as well as the callback declarations (I am not entirely sure how to implement TaskDialogCallbackProc). PS: I am looking for a direct WinAPI implementation, not one through a wrapper.

• Persist changes in C

  - by Mohit Deshpande

  I am developing a database-like application that stores a a structure containing: struct Dictionary { char *key; char *value; struct Dictionary *next; }; As you can see, I am using a linked list to store information. But the problem begins when the user exits out of the program. I want the information to be stored somewhere. So I was thinking of storing the linked list in a permanent or temporary file using fopen, then, when the user starts the program, retrieve the linked list. Here is the method that prints the linked list to the console: void PrintList() { int count = 0; struct Dictionary *current; current = head; if (current == NULL) { printf("\nThe list is empty!"); return; } printf(" Key \t Value\n"); printf(" ======== \t ========\n"); while (current != NULL) { count++; printf("%d. %s \t %s\n", count, current->key, current->value); current = current->next; } } So I am thinking of modifying this method to print the information through fprintf instead of printf and then the program would just get the infomation from the file. Could someone help me on how I can read and write to this file? What kind of file should it be, temporary or regular? How should I format the file (like I was thinking of just having the key first, then the value, then a newline character)?

• Getting the first result from a LINQ query - why does ElementAt<T>(0) fails when First<T>() succeeds

  - by Mr Roys

  I have a method AddStudent() which looks for a student with the same name and returns an existing student from the database if there is a student with the same name, otherwise it creates a new student and adds it to the database. I'm curious why se = students.First<StudentEntity>(); succeeds when se = students.ElementAt<StudentEntity>(0); fails when I try to get the first result from the LINQ query. Aren't the two methods the same? The full code for the method is shown below. public Student AddStudent(string name) { using (SchoolEntities db = new SchoolEntities()) { // find student with same name via LINQ var students = from s in db.StudentEntitySet where s.name == name select s; StudentEntity se = default(StudentEntity); // if student with the same name is already present, return // that student if (students.Count<StudentEntity>() > 0) { // if i use ElementAt, if fails with a "LINQ to Entities does not // recognize the method 'StudentEntity ElementAt[StudentEntity] // (System.Linq.IQueryable`1[StudentEntity], Int32)' method, // and this method cannot be translated into a store expression.", // but not when I use First. Why? // se = students.ElementAt<StudentEntity>(0); se = students.First<StudentEntity>(); } else { // passing 0 for first parameter (id) since it's represented by // a BigInt IDENTITY field in the database so any value // doesn't matter. se = StudentEntity.CreateStudentEntity(0, name); db.AddToStudentEntitySet(se); db.SaveChanges(); } // create a Student object from the Entity object return new Student(se); } } Thanks!

• Best approach, Dynamic OpenXML in T-SQL

  - by Martin Ongtangco

  hello, i'm storing XML values to an entry in my database. Originally, i extract the xml datatype to my business logic then fill the XML data into a DataSet. I want to improve this process by loading the XML right into the T-SQL. Instead of getting the xml as string then converting it on the BL. My issue is this: each xml entry is dynamic, meaning it can be any column created by the user. I tried using this approach, but it's giving me an error: CREATE PROCEDURE spXMLtoDataSet @id uniqueidentifier, @columns varchar(max) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; DECLARE @name varchar(300); DECLARE @i int; DECLARE @xmlData xml; (SELECT @xmlData = data, @name = name FROM XmlTABLES WHERE (tableID = ISNULL(@id, tableID))); EXEC sp_xml_preparedocument @i OUTPUT, @xmlData DECLARE @tag varchar(1000); SET @tag = '/NewDataSet/' + @name; DECLARE @statement varchar(max) SET @statement = 'SELECT * FROM OpenXML(@i, @tag, 2) WITH (' + @columns + ')'; EXEC (@statement); EXEC sp_xml_removedocument @i END where i pass a dynamically written @columns. For example: spXMLtoDataSet 'bda32dd7-0439-4f97-bc96-50cdacbb1518', 'ID int, TypeOfAccident int, Major bit, Number_of_Persons int, Notes varchar(max)' but it kept on throwing me this exception: Msg 137, Level 15, State 2, Line 1 Must declare the scalar variable "@i". Msg 319, Level 15, State 1, Line 1 Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

• AJAX - querying a search engine and returning the number of results

  - by Moddy

  Right, so basically I need to query a selection of search engines in an AJAX app. As there is a number of different search engines - there's no search engine specific API I can use either. My main problem is getting the number of results returned by the search. So far, I have decided it is probably best to use a regexp from the returned search query HTML, and then convert the string of characters to an integer. However, this method just doesn't feel.. clean to me. It seems a bit rough around the edges and I think it could do with improving! I guess not being 100% confident with regular expressions doesn't help; but it just feels like it could be improved. Any ideas on how to implement this would be great cheers! It doesn't seem like that an exotic thing to do, so I was wondering if perhaps any of you guys have done this before and would have a few tips? Note: This is an AJAX app at the moment, but I may be re-writing this functionality in a different app soon - which won't be AJAX. I'm confident I can transfer any AJAX implementation to the other language though.

• Why does findstr not handle case properly (in some circumstances)?

  - by paxdiablo

  While writing some recent scripts in cmd.exe, I had a need to use findstr with regular expressions - customer required standard cmd.exe commands (no GnuWin32 nor Cygwin nor VBS nor Powershell). I just wanted to know if a variable contained any upper-case characters and attempted to use: > set myvar=abc > echo %myvar%|findstr /r "[A-Z]" abc > echo %errorlevel% 0 When %myvar% is set to abc, that actually outputs the string and sets errorlevel to 0, saying that a match was found. However, the full-list variant: > echo %myvar%|findstr /r "[ABCDEFGHIJKLMNOPQRSTUVWXYZ]" > echo %errorlevel% 1 does not output the line and it correctly sets errorlevel to 1. In addition: > echo %myvar%|findstr /r "^[A-Z]*$" > echo %errorlevel% 1 also works as expected. I'm obviously missing something here even if it's only the fact that findstr is somehow broken. Why does the first (range) regex not work in this case? And yet more weirdness: > echo %myvar%|findstr /r "[A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z][A-Z]" > echo %myvar%|findstr /r "[A]" The last two above also does not output the string!!

• How does this code break the Law of Demeter?

  - by Dave Jarvis

  The following code breaks the Law of Demeter: public class Student extends Person { private Grades grades; public Student() { } /** Must never return null; throw an appropriately named exception, instead. */ private synchronized Grades getGrades() throws GradesException { if( this.grades == null ) { this.grades = createGrades(); } return this.grades; } /** Create a new instance of grades for this student. */ protected Grades createGrades() throws GradesException { // Reads the grades from the database, if needed. // return new Grades(); } /** Answers if this student was graded by a teacher with the given name. */ public boolean isTeacher( int year, String name ) throws GradesException, TeacherException { // The method only knows about Teacher instances. // return getTeacher( year ).nameEquals( name ); } private Grades getGradesForYear( int year ) throws GradesException { // The method only knows about Grades instances. // return getGrades().getForYear( year ); } private Teacher getTeacher( int year ) throws GradesException, TeacherException { // This method knows about Grades and Teacher instances. A mistake? // return getGradesForYear( year ).getTeacher(); } } public class Teacher extends Person { public Teacher() { } /** * This method will take into consideration first name, * last name, middle initial, case sensitivity, and * eventually it could answer true to wild cards and * regular expressions. */ public boolean nameEquals( String name ) { return getName().equalsIgnoreCase( name ); } /** Never returns null. */ private synchronized String getName() { if( this.name == null ) { this.name == ""; } return this.name; } } Questions How is the LoD broken? Where is the code breaking the LoD? How should the code be written to uphold the LoD?

• Javascript: Multiple mouseout events triggered

  - by Channel72

  I'm aware of the different event models in Javascript (the WC3 model versus the Microsoft model), as well as the difference between bubbling and capturing. However, after a few hours reading various articles about this issue, I'm still unsure how to properly code the following seemingly simple behavior: If I have an outer div and an inner div element, I want a single mouse-out event to be triggered when the mouse leaves the outer-div. When the mouse crosses from the inner-div to the outer-div, nothing should happen, and when the mouse crosses from the outer-div to the inner-div nothing should happen. The event should only fire if the mouse moves from the outer-div to the surrounding page. <div id="outer" style = "width:20em; height:20em; border:1px solid #F00" align = "center" onmouseout="alert('mouseout event!')" > <div id="inner" style = "width:18em; height:18em; border:1px solid #000"></div> </div> Now, if I place the "mouseout" event on the outer-div, two mouse-out events are fired when the mouse moves from the inner-div to the surrounding page, because the event fires once when the mouse moves from inner to outer, and then again when it moves from outer to the surrounding page. I know I can cancel the event using ev.stopPropagation(), so I tried registering an event handler with the inner-div to cancel the event propagation. However, this won't prevent the event from firing when the mouse moves from the outer-div to the inner-div. So, unless I'm overlooking something, it seems to me this behavior can't be accomplished without complex mouse-tracking functions. In the future, I plan to reimplement a lot of this code using a more advanced framework, like JQuery, but for now, I'm wondering if there is a simple way to implement the above behavior in regular Javascript.

• Extension Methods and Application Code

  - by Mystagogue

  I have seen plenty of online guidelines for authoring extension methods, usually along these lines: 1) Avoid authoring extension methods when practical - prefer other approaches first (e.g. regular static methods). 2) Don't author extension methods to extend code you own or currently develop. Instead, author them to extend 3rd party or BCL code. But I have the impression that a couple more guidelines are either implied or advisable. What does the community think of these two additional guidelines: A) Prefer to author extension methods to contain generic functionality rather than application-specific logic. (This seems to follow from guideline #2 above) B) An extension method should be sizeable enough to justify itself (preferably at least 5 lines of code in length). Item (B) is intended to discourage a develoer from writing dozens of extension methods (totalling X lines of code) to refactor or replace what originally was already about X lines of inline code. Perhaps item (B) is badly qualified, or even misinformed about how a one line extension method is actually powerful and justified. I'm curious to know. But if item (B) is somehow dismissed by the community, I must admist I'm still particularly interested in feedback on guideline (A).

• Listing directories in Linux from C

  I am trying to simulate linux command ls using linux api from c. Looking at the code it does make sense, but when I run it I get "stat error: No such file or directory". I have checked that opendir is working ok. I think the problem is in stat, which is returning -1 even though I think it should return 0. What am I missing? Thanks for your help. #include <stdio.h> #include <stdlib.h> #include <string.h> #include <dirent.h> #include <sys/stat.h> #include <errno.h> int main(int argc, char *argv[]) { DIR *dirp; struct dirent *direntp; struct stat stat_buf; char *str; if (argc != 2) { fprintf( stderr, "Usage: %s dir_name\n", argv[0]); exit(1); } if ((dirp = opendir( argv[1])) == NULL) { perror(argv[1]); exit(2); } while ((direntp = readdir( dirp)) != NULL) { if (stat(direntp->d_name, &stat_buf)==-1) { perror("stat ERROR"); exit(3); } if (S_ISREG(stat_buf.st_mode)) str = "regular"; else if (S_ISDIR(stat_buf.st_mode)) str = "directory"; else str = "other"; printf("%-25s - %s\n", direntp->d_name, str); } closedir(dirp); exit(0); }

• How do I show information to users belonging to different groups (web) in modx

  - by Gaurav Sharma

  Hello Everyone, I have created a website using modx evolution v1.0.2. The website that I have developed has 12 different types of users (categorized in groups). Each user will be shown a different price depending on the group to which he belongs. Till now I have been able to fetch the group name of current logged in user (created a snippet for that), but how can I achieve the above mentioned functionality so that each user should be able to see only the price that I have coded according to his group. For example: If a user is associated with the 'ocassional' group then he should be shown the price as , say, 50 bucks and if a user is associated with the 'regular' group then he should be shown the price as, say, 40 bucks I can easily do this by coding a single snippet for every product's variant, but there are a lot of variants (more than 100 and growing). I have created a resource(page) for every product and it's variant. Every variant has a price. It is this price that I want to be shown according to the logged in user group membership. I hope I am able to explain my query clearly. Please help me do this functionality. Thanks

• How do you localize/internationalize an MVC Controller when using a SQL based localization provider?

  - by EBarr

  Hopefully this isn't too silly of a question. In MVC there appears to be plenty of localization support in the views. Once I get to the controller, however, it becomes murky. Using meta:resourcekey="blah" is out, same with <%$ Resources:PageTitle.Text%. ASP.NET MVC - Localization Helpers -- suggested extensions for the Html helper classes like Resource(this Controller controller, string expression, params object[] args). Similarly, Localize your MVC with ease suggested a slightly different extension like Localize(this System.Web.UI.UserControl control, string resourceKey, params object[] args) None of these approaches works while in a controller. I put together the below function and I'm using the controllers full class name as my VirtualPath. But I'm new to MVC and assume there's a better way. public static string Localize (System.Type theType, string resourceKey, params object[] args) { string resource = (HttpContext.GetLocalResourceObject(theType.FullName, resourceKey) ?? string.Empty).ToString(); return mergeTokens(resource, args); } Thoughts? Comments?

• Receiving an object in a unmanaged callback function

  - by Daniel Baulig

  Eg. I have following delegate method I want to use as a callback function with unmanaged code: public delegate void Callback(IntPtr myObject); Callback callback; I register it in the following way: [DllImport("a.dll")] public static void registerCallback(IntPtr callbackFunction, IntPtr anObject); // ... this.myObject = new MyClass(); this.objectPin = GCHandle.Alloc(this.myObject, GCHandleType.Pinned); registerCallback(Marshal.GetFunctionPointerForDelegate(callback), objectPin.AddrOfPinnedObject()); Now whenever the callback function is called it will have a Pointer/Handle of an object of the MyClass class. I could use Marshal.PtrToStructure to convert this to an object of MyClass. However, what I would like to have is that the delegate definition already contains the class MyClass. eg.: public delegate void Callback(MyClass myObject); I tried this, but it will not work. I also tried the following, which did not work: public delegate void Callback([MarshalAs(UnmanagedType.IUnknown)]MyClass myObject); I suppose I would need something like "UnmarshalAs" at this point, but sadly this is not available. Any suggestions how I could get lost of that IntPtr in my callback function and get a it packed up as a regular, managed MyClass object?

• python histogram one-liner

  - by mykhal

  there are many ways, how to code histogram in Python. by histogram, i mean function, counting objects in an interable, resulting in the count table (i.e. dict). e.g.: >>> L = 'abracadabra' >>> histogram(L) {'a': 5, 'b': 2, 'c': 1, 'd': 1, 'r': 2} it can be written like this: def histogram(L): d = {} for x in L: if x in d: d[x] += 1 else: d[x] = 1 return d ..however, there are much less ways, how do this in a single expression. if we had "dict comprehensions" in python, we would write: >>> { x: L.count(x) for x in set(L) } but we don't have them, so we have to write: >>> dict([(x, L.count(x)) for x in set(L)]) however, this approach may yet be readable, but is not efficient - L is walked-through multiple times, so this won't work for single-life generators.. the function should iterate well also through gen(), where: def gen(): for x in L: yield x we can go with reduce (R.I.P.): >>> reduce(lambda d,x: dict(d, x=d.get(x,0)+1), L, {}) # wrong! oops, does not work, the key name is 'x', not x :( i ended with: >>> reduce(lambda d,x: dict(d.items() + [(x, d.get(x, 0)+1)]), L, {}) (in py3k, we would have to write list(d.items()) instead of d.items(), but it's hypothethical, since there is no reduce there) please beat me with a better one-liner, more readable! ;)

• How to properly force a Blackberry Java application to install using Loader.exe

  - by Kevin White

  I want to include the Application Loader process in a software installation, to ensure that users get our software installed on their Blackberry by the time our installer software finishes. I know this is possible, because Aerize Card Loader (http://aerize.com/blackberry/software/loader/) does this. When you install their software, if your Blackberry is connected the Application Loader will come up and force the .COD file to install to the device. I can't make it work. Looking at RIM's own documentation, I need to: Place the ALX and COD files into a subfolder here: C:\Program Files\Common Files\Research In Motion\Shared\Applications\ Add a path to the ALX file in HKCU\Software\Research In Motion\Blackberry\Loader\Packages Index the application, by executing this at the command line: loader.exe /index Start the force load, by doing this: loader.exe /defaultUSB /forceload When I execute that last command, the Application Loader comes up and says that all applications are up to date and nothing needs to be done. If I execute loader.exe by double-clicking on it (or typing in the command with no parameters), I get the regular Application Loader wizard. It shows my program as listed, but un-checked. If I check it and click next, it will install to the Blackberry. (This is the part that I want to avoid, and that Aerize Card Loader's install process avoids.) What am I missing? It appears that the Aerize installer is doing something different but I haven't been able to ascertain what.

• Encoding MySQL text fields into UTF-8 text files - problems with special characters

  - by Matt Andrews

  I'm writing a php script to export MySQL database rows into a .txt file formatted for Adobe InDesign's internal markup. Exports work, but when I encounter special characters like é or umlauts, I get weird symbols (eg Chloë Hanslip instead of Chloë Hanslip). Rather than run a search and replace for every possible weird character, I need a better method. I've checked that when the text hits the database, it's saved properly - in the database I see the special characters. My export code basically runs some regular expressions to put in the InDesign code tags, and I'm left with the weird symbols. If I just output the text to the browser (rather than prompt for a text file download), it displays properly. When I save the file I use this code: header("Content-disposition: attachment; filename=test.txt"); header("Content-Type: text/plain; charset=utf-8"); I've tried various combinations of utf8_encode() and iconv() to no avail. Can anybody point me in the right direction here?

• invalid argument IE7 javascript line number changes

  - by Lauren

  This is the test page: http://www.onebagoneearth.com/ OBOEKindBag (spaces between the pagename and domain because I don't want the URL indexed as such) If you click on one of the thumbnails, or on the main image, you see a popup window, and if you enter a quantity and then click "add to cart" here, in IE7 (and IE6, but I'm not focusing on that as much), you see an invalid argument error with Code:0. The line # changes depending on which item you add to cart! The URL also changes because it depends on this line of javascript: var cartUrl = "/app/site/backend/additemtocart.nl?c=659197&n=2&buyid=" + zbuyid + "&qty=" + zqty + "&" + strOptionId + "=" + zitmId . The strOptionId variable, which contains the bag color type (ie. this changes for the different types of bags, like Kind bags, regular OBOE bags), and the zitmID variable which contains the particular bag color that you've selected (ie. Black), are what change, and also what seem to affect the line number that the invalid argument occurs on. The error definitely doesn't occur in Chrome 4, IE 8, or FF 3.5. Ideas?

  Hi. I'm getting this error The type or namespace name 'DataVisualization' does not exist in the namespace 'System.Windows.Forms' (are you missing an assembly reference?) Here is my using section of the class: using System; using System.Collections; using System.Collections.Generic; using System.Windows.Forms.DataVisualization.Charting; using System.Windows.Forms.DataVisualization.Charting.Borders3D; using System.Windows.Forms.DataVisualization.Charting.ChartTypes; using System.Windows.Forms.DataVisualization.Charting.Data; using System.Windows.Forms.DataVisualization.Charting.Formulas; using System.Windows.Forms.DataVisualization.Charting.Utilities; namespace myNamespace { public class myClass { // Usual class stuff } } The thing is that I am using the same DataVisualization includes in another class. The only thing that I can think that is different is that the classes that are giving this missing namespace error are Solution Items rather than specific to a project. The projects reference them by link. Anyone have thoughts on what the problem is? I've installed the chart component, .Net 3.5 SP1, and the Chart Add-in for Visual Studio 2008. UPDATE: I moved the items from Solution Items to be regular members of my project and I'm still seeing the same behavior. UPDATE 2: Removing the items from the Solution Items and placing them under my project worked. Another project was still referencing the files which is why I didn't think it worked previously. I'm still curious, though, why I couldn't use the namespace when the classes were Solution Items but moving them underneath a project (with no modifications, mind you) instantly made them recognizable. :\

• Problem consuming Exchange Web Service 2010 with jax-ws metro

  - by Johan Karlberg

  I am trying to consume the Exchange 2010 Web Service interface using JAX-WS. I'm using JAX-WS 2.2 RI (Metro 2.0). 2.1 exhibited the same problem. I am running into trouble with Exchange, which returns "HTTP/1.1 415 Cannot process the message because the content type 'text/xml;charset=utf-8' was not the expected type 'text/xml; charset=utf-8'." as a reponse (2.1 quoted the charset value, otherwise same response). Apparently I need to dictate the exact Content-type header for Exchange to be happy. Is there a way for me to do this without forcing me to manually rebuild the dependency? I currently rely on published maven artifacts, and would like to continue doing this if at all possible. The consuming process is a regular J2SE app, with no containers in sight. I have control of the application and can add pretty much anything required to the applications scope, but can not add out-of-process items like proxy servers. The client classes were generated from local WSDL, but the charset specification is derived from constants declared in the jaxws RI implementation, not the generated code. The resulting HTTP transport is thus handled by the standard http/https client from Sun JRE5 or JRE6.
