  • Events not sent to WPF based ActiveX control (COM interop) when using Reg-Free-COM

    - by embnut
    I have a WPF based ActiveX control (COM interop). I am able to use it correctly by registering the control. When I tried to Reg-Free-COM (using manifest files) the control seems to be activated, but the events (such as mouse click, RequestBringIntoView etc) dont respond. Interestingly, Double click and tab key works. I read in the this article http://blogs.msdn.com/karstenj/archive/2006/10/09/activex-wpf-gadget.aspx that " ... These upsides come with a price: the ActiveX control must be registered in the registry, which requires some kind of installation such as an .msi. The default gadget installation process cannot install ActiveX. The ActiveX control can't be access via reg-free COM. ..." Has anybody had a similar experience? Can anyone explain what is going on? Additional details: When the control is activated after it has been registered it appears as part of the COM client's UI. The control does not receive focus, its elements receive it. When using reg-free-com the control does not load correctly. 1) The control receives focus instead of its sub elements 2) The control has areas that are black instead of the windows default color 3) when I tab in and out of the control or double click it, it's subelements receive focus, the control starts receiving events and the black areas are replaced by the correct color

  • Detecting Asymptotes in a Graph

    - by nasufara
    I am creating a graphing calculator in Java as a project for my programming class. There are two main components to this calculator: the graph itself, which draws the line(s), and the equation evaluator, which takes in an equation as a String and... well, evaluates it. To create the line, I create a Path2D.Double instance, and loop through the points on the line. To do this, I calculate as many points as the graph is wide (e.g. if the graph itself is 500px wide, I calculate 500 points), and then scale it to the window of the graph. Now, this works perfectly for most any line. However, it does not when dealing with asymptotes. If, when calculating points, the graph encounters a domain error (such as 1/0), the graph closes the shape in the Path2D.Double instance and starts a new line, so that the line looks mathematically correct. Example: However, because of the way it scales, sometimes it is rendered correctly, sometimes it isn't. When it isn't, the actual asymptotic line is shown, because within those 500 points, it skipped over x = 2.0 in the equation 1 / (x-2), and only did x = 1.98 and x = 2.04, which are perfectly valid in that equation. Example: In that case, I increased the window on the left and right one unit each. My question is: Is there a way to deal with asymptotes using this method of scaling so that the resulting line looks mathematically correct? I myself have thought of implementing a binary search-esque method, where, if it finds that it calculates one point, and then the next point is wildly far away from the last point, it searches in between those points for a domain error. I had trouble figuring out how to make it work in practice, however. Thank you for any help you may give!

  • Stop IE users typing into the file upload input

    - by Dexter
    My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted). I am able to replicate this with the following ASPX code (with no code behind): <%@ Page Language="C#" AutoEventWireup="true" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <body> <form id="form1" runat="server"> <div> <asp:FileUpload ID="fuTest" runat="server" /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> </div> </form> </body> </html> (Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box) Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields. I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers. Any thoughts?

  • VERY simple C program won't compile with VC 64

    - by Paperflyer
    Here is a very simple C program: #include <stdio.h> int main (int argc, char *argv[]) { printf("sizeof(short) = %d\n",(int)sizeof(short)); printf("sizeof(int) = %d\n",(int)sizeof(int)); printf("sizeof(long) = %d\n",(int)sizeof(long)); printf("sizeof(long long) = %d\n",(int)sizeof(long long)); printf("sizeof(float) = %d\n",(int)sizeof(float)); printf("sizeof(double) = %d\n",(int)sizeof(double)); return 0; } While it compiles fine on Win32 (command line: cl main.c), it does not using the Win64 compiler ("c:\Program Files(x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\cl.exe" main.c). Specifically, it sais "error LNK2019: unresolved external symbol printf referenced in function main". As far as I understand this, it can not link to printf, right? Obviously, I have Microsoft Visual C++ Compiler 2008 (Standard enu) x86 and x64 installed and am using the 64-bit flavor of Windows (7). What is the problem here?

  • SECURITY Flaws in this design for User authentication.

    - by Shao
    SECURITY Flaws in this design for User authentication. From: http://wiki.pylonshq.com/display/pylonscookbook/Simple+Homegrown+Authentication Note: a. Project follows the MVC pattern. b. Only a user with a valid username and password is allowed submit something. Design: a. Have a base controller from which all controllers are derived from. b. Before any of the actions in the derived controllers are called the system calls a before action in the base controller. c. In each controller user hardcodes the actions that need to be verified in an array. d. The before action first looks in the array that has the actions that are protected and sees if a user is logged in or not by peaking into the session. If a user is present then user is allowed to submit otherwise user is redirected to login page. What do you think?

  • ASP.NET MVC solution to a forms application?

    - by Gloria Huang
    Hello, We're building a survey system and utilising ASP.NET MVC and wondered if anyone can offer suggestions on the architecture. Here's the problem we're trying to solve. Essentially an agency sends out several surveys every year. They're very structured and not like SurveyMonkey style of surveys - they're actually applications of feedback. Much like a Visa Application there are lots of things they need to do and sometimes it takes them 2-3 weeks to fill it out. They can upload files (proofs of purchase etc - PDF/JPG) and also multiple "items". Eg. Say for instance they've worked for McDonalds, there could be 20 different franchises, they build a list of locations they've worked. 3 weeks later there could be another 3 new locations and 2 may have closed down. So we need to ensure the forms are able to handle those situations. The forms themselves (markup and data) change every year - I should mention that this for a taxation/finance/budget system. We were thinking of using MVC, using Xml to store the data (temporarily), XSD to validate the data, XSL to transform the data to presentable markup (for them to fill out) and then once they "Submit" an application it gets stored into the DB in relevant areas. When the user starts the application process, they can save the progress so far (we validate whatever they entred and ignore any they havent), save it as an Xml blob and store in the DB. When they're finally ready to submit it, then we do a full validation and upload the files and store them securely (it has their business proofs and accounting statements) and then run some workflows. What I'm really concerned about is how to manage changing forms versions (a year later). How are form/application systems written these days? We have 2 months to pull this off and about 30 forms to deliver. So 30xXML, 30xXSD, 30xXSL.

  • using alias parameters in window command prompt

    - by freshWoWer
    Source:http://jpsoft.com/help/index.htm?alias.htm Aliases can use command line parameters or parameters like those in batch files. The command line parameters are numbered from %0 to %511. (%0 contains the alias name.) For example, the following alias will change directories, perform a command, and return to the original directory: alias in pushd %1 & %2$ & popd when i run the above, my command prompt gives error saying %1 * Unable to read value of alias * '%2' is not recognized as an internal or external command, operable program or batch file. 'popd`' is not recognized as an internal or external command, operable program or batch file. if you use double quote instead, alias in "pushd %1 & dir & popd" it doesn't interprets the %1 when you execute the alias C:\abc\defalias Dumping all defined aliases for CMD.EXE. in =pushd %1 & dir & popd alias def wont work ---------EDIT------------ let me try some sample output with a simple echo alias D:\abc\defalias /? Usage: ALIAS [-v] [-p programName] [-f filespec] [ ] [-v] means verbose output. [-d] means delete aliases. [-p programName] specifies which image file name these alias definitions are for. Default is CMD.EXE [-f filespec] specifies a file which contains the alises. C:\Office\dev15alias out 'echo %1' %1' * Unable to read value of alias * C:\Office\dev15alias out backtick echo %1 backtick %1` * Unable to read value of alias * C:\Office\dev15alias out "echo %1" C:\Office\dev15alias Dumping all defined aliases for CMD.EXE. out =echo %1 C:\Office\dev15out abc %1 C:\Office\dev15alias out echo %1 %1 * Unable to read value of alias * C:\Office\dev15out abc ECHO is on. Problem is, both single quote and back tick produces error, while double quote wont treat %1 as variable parameter

  • Null Reference Exception In LINQ DataContext

    - by Frank
    I have a Null Reference Exception Caused by this code: var recentOrderers = (from p in db.CMS where p.ODR_DATE > DateTime.Today - new TimeSpan(60, 0, 0, 0) select p.SOLDNUM).Distinct(); result = (from p in db.CMS where p.ORDER_ST2 == "SH" && p.ODR_DATE > DateTime.Today - new TimeSpan(365, 0, 0, 0) && p.ODR_DATE < DateTime.Today - new TimeSpan(60, 0, 0, 0) && !(recentOrderers.Contains(p.SOLDNUM))/**/ select p.SOLDNUM).Distinct().Count(); result is of double type. When I comment out: !(recentOrderers.Contains(p.SOLDNUM)) The code runs fine. I have verified that recentOrderers is not null, and when I run: if(recentOrderes.Contains(0)) return; Execution follows this path and returns. Not sure what is going on, since I use similar code above it: var m = (from p in db.CMS where p.ORDER_ST2 == "SH" select p.SOLDNUM).Distinct(); double result = (from p in db.CUST join r in db.DEMGRAPH on p.CUSTNUM equals r.CUSTNUM where p.CTYPE3 == "cmh" && !(m.Contains(p.CUSTNUM)) && r.ColNEWMEMBERDAT.Value.Year > 1900 select p.CUSTNUM).Distinct().Count(); which also runs flawlessly. After noting the similarity, can anyone help? Thanks in advance. -Frank GTP, Inc.

  • ASP.NET MVC Facebook

    - by durilai
    I am trying to do a seemingly simple thing, but having trouble accomplishing it. I am trying to automate the posting on my Facebook wall. Basically I have a ASP.NET MVC website that I post updates on, and I want to automatically submit the post to my wall. I see a lot of stuff on FB Connect and getting data, I just want to post. Thanks for any help or guidance. UPDATE: Just trying to resurrect, and be a little more clear in my description as I am not getting anywhere. I have a page that I want with a text box and a button. When I submit the form I want the message to post to my Facebook wall. I thought it was Facebook Connect, but I am getting no where as to how to automatically authenticate myself and post to my wall. I would like to use C# rather than JavaScript. private const string ApplicationKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXX"; private const string SecretKey = "XXXXXXXXXXXXXXXXXXXXXXXXXX"; private Facebook.Rest.Api _facebookAPI; private Facebook.Session.ConnectSession _connectSession; [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(FormCollection form) { _connectSession = new Facebook.Session.ConnectSession(ApplicationKey, SecretKey); if (_connectSession.IsConnected()) { _facebookAPI = new Facebook.Rest.Api(_connectSession); string response = _facebookAPI.Stream.Publish("This is a generated test"); } return View(); } } The IsConnected() is returning false. Any help is appreciated.

  • Get Mechanize to handle cookies from an arbitrary POST (to log into https://www.t-mobile.com/ progra

    - by Horace Loeb
    I want to log into https://www.t-mobile.com/ programmatically. My first idea was to use Mechanize to submit the login form: However, it turns out that this isn't even a real form. Instead, when you click "Log in" some javascript grabs the values of the fields, creates a new form dynamically, and submits it. "Log in" button HTML: <button onclick="handleLogin(); return false;" class="btnBlue" id="myTMobile-login"><span>Log in</span></button> The handleLogin() function: function handleLogin() { if (ValidateMsisdnPassword()) { // client-side form validation logic var a = document.createElement("FORM"); a.name = "form1"; a.method = "POST"; a.action = mytmoUrl; // defined elsewhere as https://my.t-mobile.com/Login/LoginController.aspx var c = document.createElement("INPUT"); c.type = "HIDDEN"; c.value = document.getElementById("myTMobile-phone").value; // the value of the phone number input field c.name = "txtMSISDN"; a.appendChild(c); var b = document.createElement("INPUT"); b.type = "HIDDEN"; b.value = document.getElementById("myTMobile-password").value; // the value of the password input field b.name = "txtPassword"; a.appendChild(b); document.body.appendChild(a); a.submit(); return true } else { return false } } I could simulate this form submission by POSTing the form data to https://my.t-mobile.com/Login/LoginController.aspx with Net::HTTP#post_form, but I don't know how to get the resultant cookie into Mechanize so I can continue to scrape the UI available when I'm logged in. Any ideas?

  • How can I get jQuery validation plugin Ketchup to stop an Ajax form submission when validation fails?

    - by Marshall Sontag
    I'm using Ruby on Rails, Formtastic gem, jQuery and ketchup to validate my form. I'm submitting the form created by Formtastic inside a modal box using ajax: <% semantic_form_remote_for @contact_form, :url => '/request/contact' do |f| %> I have a validation plugin verifying the fields on the form: $(document).ready(function() { $("#new_contact_form").ketchup(); }); The problem is that semantic_form_remote_for generates an onSubmit ajax request that the jQuery validation plugins won't prevent, since it's not a normal form submission. One question on stackoverflow suggests using :condition on the remote form declaration to fire a javascript function, but I can't do that since I'm not using a function, but rather relying on a jQuery handler. I also tried putting ketchup within a submit event handler: $(document).ready(function() { $("#new_contact_form").submit(function() { $('#new_contact_form').ketchup(); }); }); No luck. Form still submits. I also tried using the beforeSend option of jQuery.ajax: $(document).ready(function() { jQuery.ajax( { beforeSend: function(){ $('#new_contact_form').ketchup(); } }); }); Validation fires off, but form is still submitted. I switched to jQuery Validation plugin just to see if it was due to some limitation in Ketchup. It turns out that Validation has a submitHandler option: $(document).ready(function() { $('#new_contact_form').validate({ submitHandler: function(form) { jQuery.ajax({ data:jQuery.param(jQuery('#new_contact_form').serializeArray()), dataType:'script', type:'post', url:'/request/contact' }); return false; } }); }); This works when I use a regular semantic_form_for instead of semantic_form_remote_for, but alas, I would rather use Ketchup. Is Ketchup just woefully lacking? Am I forced to use jQuery Validation?

  • Does Firefox on OS X Lion make use of Full Page Zoom for the touchpad? How to customize behavior?

    - by Steven Lu
    I really like the smooth pinch-zoom of Safari using the touchpad, but the two-finger scroll on Firefox is so much better than the scrolling performance in Safari. So I really like to use Firefox, but then I miss out on two-finger-double-tap to zoom to paragraph width, and the smooth pinch gesture zoom. What I'm wondering is if it is possible to write a Firefox Extension to improve the update rate of the full-page zoom in Firefox that is already functioning via the touchpad pinch gesture. I feel like it is specifically programmed to zoom at certain zoom levels: 100%, 120%, 150% (these are guesses of mine) but I think it would be great if I can get some more control there to make it work more like the zoom functionality in Safari. Also the two-finger-double-tap on a paragraph or element to zoom to it would be really awesome as well. https://developer.mozilla.org/en/Full_page_zoom This seems to indicate (if "full page zoom" is what I think it is) that an extension has the ability to zoom to an arbitrary scale factor, but what remains is to find out if it is possible to obtain or hook the touchpad pinch gesture. Update: I have updated the toolkit.zoomManager.zoomValues option in about:config to include more zoom levels: .3,.5,.67,.8,.9,1,1.01,1.02,1.03,1.04,1.05,1.06,1.07,1.08,1.09,1.1,1.2,1.33,1.5,1.7,2,2.4,3 Notice how I inserted a bunch of entries between 1 and 1.1. But it isn't switching between them any faster (why would it?) so it's less usable than before because of waiting for it to respond fast enough. It's clear that re-rendering the page at a different zoom level requires time and in order for the zoom to be dynamic, some kind of screen capture and scale effect must be performed (which is what Safari does). I guess such a thing is probably doable but I don't think I could pull it off. :-/

  • Problem with detecting the value of the drop down list on the server (servlet) side

    Client code is pretty simple: <form action="DDServlet" method="post"> <input type="text" name="customerText"> <select id="customer"> <option name="customerOption" value="3"> Tom </option> <option name="customerOption" value="2"> Harry </option> </select> <input type="submit" value="send"> </form> Here is the code on the Servlet Enumeration paramNames = request.getParameterNames(); while(paramNames.hasMoreElements()){ String paramName = (String)paramNames.nextElement(); //get the next element System.out.println(paramName); } When I print out, I only see, customerText, but not customerOption. Any idea why guys? What I hope is, if I select Tom in my option, once I submit, on my servlet I should able to do this: String paramValues[] = request.getParameterValues(paramName); and get back value of 3

  • How to construct LambdaExpression with conversion

    - by nerijus
    I need to sort in ajax response grid by column name. Column value is number stored as a string. Let's say some trivial class (in real-life situation there is no possibility to modify this class): class TestObject { public TestObject(string v) { this.Value = v; } public string Value { get; set; } } then simple test: [Test] public void LambdaConstructionTest() { var queryable = new List<TestObject> { new TestObject("5"), new TestObject("55"), new TestObject("90"), new TestObject("9"), new TestObject("09"), new TestObject("900"), }.AsQueryable(); var sortingColumn = "Value"; ParameterExpression parameter = Expression.Parameter(queryable.ElementType); MemberExpression property = Expression.Property(parameter, sortingColumn); //// tried this one: var c = Expression.Convert(property, typeof(double)); LambdaExpression lambda = Expression.Lambda(property, parameter); //// constructs: o=>o.Value var callExpression = Expression.Call(typeof (Double), "Parse", null, property); var methodCallExpression = Expression.Call( typeof(Queryable), "OrderBy", new[] { queryable.ElementType, property.Type }, queryable.Expression, Expression.Quote(lambda)); // works, but sorts by string values. //Expression.Quote(callExpression)); // getting: System.ArgumentException {"Quoted expression must be a lambda"} var querable = queryable.Provider.CreateQuery<TestObject>(methodCallExpression); // return querable; // <- this is the return of what I need. } Sorry for not being clear in my first post as @SLaks answer was correct but I do not know how to construct correct lambda expression in this case.

  • PHP jQuery Long Polling Chat Application

    - by Tejas Jadhav
    I've made a simple PHP jQuery Chat Application with Short Polling (AJAX Refresh). Like, every 2 - 3 seconds it asks for new messages. But, I read that Long Polling is a better approach for Chat applications. So, I went through some Long Polling scripts. I made like this: Javascript: $("#submit").click(function(){ $.ajax({ url: 'chat-handler.php', dataType: 'json', data: {action : 'read', message : 'message'} }); }); var getNewMessage = function() { $.ajax({ url: 'chat-handler.php', dataType: 'json', data: {action : 'read', message : 'message'}, function(data){ alert(data); } }); getNewMessage(); } $(document).ready(getNewMessage); PHP <?php $time = time(); while ((time() - $time) < 25) { $data = $db->getNewMessage (); if (!empty ($data)) { echo json_encode ($data); break; } usleep(1000000); // 1 Second } ?> The problem is, once getNewMessage() starts, it executes unless it gets some response (from chat-handler.php). It executes recursively. But if someone wants to send a message in between, then actually that function ($("#submit").click()) never executes as getNewMessage() is still executing. So is there any workaround?

  • Distributed development systems

    - by Nathan Adams
    I am interested in a system that allows for distributed development with an authentication piece. What do I mean by that? Ok so lets take SVN, SVN keeps track of revisions and doesn't care who submits, as long as you have the right to submit you can submit, really, to any part in the repository. Where does my system come into play? Being able to granulate access control and give a stackoverflow like feel to the environment. In the system I am describing we have 4 users Bob, Alice, Dan, Joe. Bob is a project managed, Alice and Dan are programmers under Bob and Joe is a random programmer on the internet who wants to help. Ideally in this system, Bob can commit any changes and won't require approval. Alice and Dan can commit to their branches, or a branch, but a commit to the trunk would need approval by Bob. This is where Joe comes in, wants to help, however, you just don't want to give him the keys to the kingdom just yet so to speak, so in my system you would setup a "low user" account. Any commits that Joe makes would need to be approved by Dan, Alice or both. However, in the system, Joe can build up "Karma" where after so many approved commits it would only need approval by one of the programmers, and then eventually no approval would be necessary. Does that make sense and do you know if a system like that exists? Or am I just crazy to even think such a system/environment would be possible?

  • Resizing window causes black strips

    - by Paja
    I have a form, which sets these styles in constructor: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); And I draw some rectangles in Paint event. There are no controls on the form. Hovewer, when I resize the form, there are black strips at right and bottom of the form. Is there any way to get rid of them? I've tried everything, listening for WM_ERASEBKGND in WndProc, manually drawing the form on WM_PAINT, implementing custom double buffer, etc. Is there anything else I could try? I've found this: https://connect.microsoft.com/VisualStudio/feedback/details/522441/custom-resizing-of-system-windows-window-flickers and it looks like it is a bug in DWM, but I just hope I can do some workaround. Please note that I must use double buffering, since I want to draw pretty intense graphic presentation in the Paint event. I develop in C# .NET 2.0, Win7.

  • Xpages conditional validation: make a field required only if report is being submitted as final

    - by Randal Oulton
    Doing server-side Xpages conditional validation.... I want the follow validation to kick in only if the Report.Status field = 'Final'. (The users are allowed to submit the report as draft and come back and finish it later, when they submit as draft we don't want to make the fields required.) How would I go about this? <xp:inputTextarea style="width:75%" value="#{Report.Agenda}" id="Agenda"> <xp:this.validators> <xp:validateRequired message="Question 1 can't be blank"> </xp:validateRequired><!-- (1) --> </xp:this.validators> </xp:inputTextarea> Tried this, didn't work, was still required even if Status field not set to final :{ <xp:inputTextarea style="width:75%" value="#{Report.Agenda}" id="Agenda" defaultValue="5 year agenda"> <xp:this.validators> <xp:validateRequired message="Question 1 can't be blank"></xp:validateRequired><!-- (1) --> <xp:validateExpression message="Question 1 can't be blank"> <xp:this.expression><![CDATA[#{javascript: if (Report.getItemValueString('Status')!='Final') { return true; } else { return false; } }]]></xp:this.expression> </xp:validateExpression> </xp:this.validators> </xp:inputTextarea>

If you didnt choose any (empty isset?) then false.. else echo Y or N(what you picked)

  • Script working with mysql and php into a textarea and back

    - by Tribalcomm
    I am trying to write a custom script that will keep a list of strings in a textarea. Each line of the textarea will be a row from a table. The problem I have is how to work the script to allow for adding, updating, or deleting rows based on a submit. So, for instance, I currently have 3 rows in the database: john sue mark I want to be able to delete sue and add richard and it will delete the row with sue and insert a row for richard. My code so far is as follows: To query the db and list it in the textarea: $basearray = mysql_query("SELECT name FROM mytable ORDER BY name"); <textarea name="names" cols=6 rows=12>'); <?php foreach($basearray as $base){ echo $base->name."\n"; } ?> </textarea> After the submit, I have: <?php $namelist = $_REQUEST[names]; $newarray = explode("\n", $namelist); foreach($newarray as $name) { if (!in_array($name, $basearray)) { mysql_query(DELETE FROM mytable WHERE word='$name'"); } elseif (in_array($name, $basearray)) { ; } else { mysql_query("INSERT INTO mytable (name) VALUES ("$name")"); } } ?> Please tell me what I am doing wrong. I am not getting any functions to work when I edit the contents of the textarea. Thanks!

  • Text Parsing - My Parser Skipping commands

    - by The.Anti.9
    I'm trying to parse text-formatting. I want to mark inline code, much like SO does, with backticks (`). The rule is supposed to be that if you want to use a backtick inside of an inline code element, You should use double backticks around the inline code. like this: `` mark inline code with backticks ( ` ) `` My parser seems to skip over the double backticks completely for some reason. Heres the code for the function that does the inline code parsing: private string ParseInlineCode(string input) { for (int i = 0; i < input.Length; i++) { if (input[i] == '`' && input[i - 1] != '\\') { if (input[i + 1] == '`') { string str = ReadToCharacter('`', i + 2, input); while (input[i + str.Length + 2] != '`') { str += ReadToCharacter('`', i + str.Length + 3, input); } string tbr = "``" + str + "``"; str = str.Replace("&", "&amp;"); str = str.Replace("<", "&lt;"); str = str.Replace(">", "&gt;"); input = input.Replace(tbr, "<code>" + str + "</code>"); i += str.Length + 13; } else { string str = ReadToCharacter('`', i + 1, input); input = input.Replace("`" + str + "`", "<code>" + str + "</code>"); i += str.Length + 13; } } } return input; } If I use single backticks around something, it wraps it in the <code> tags correctly.

  • Adding editFTPnetPRO to SSIS package causes error message

    - by gfrizzle
    I'm trying to add some secure FTP code to an SSIS package. I've used the EnterpriseDT product successfully on other .NET projects, so I wanted to incorporate it into an SSIS 2008 package I'm working on. If I create a Script Task (VB), edit the script, choose Project | Add Reference, and select the editFTPnetPRO.dll file, it comes back with this error: No template information found. See the application log in Event Viewer for more details. To open Event Viewer, click Start, click Control Panel, double-click Administrative Tools, and then double-click Event Viewer. The application log doesn't contain any pertinent details. I have no idea what this is trying to tell me. I've gone down a couple dead ends searching for this error message and following the prescribed fixes, but nothing has fixed it yet. Any idea what might be going wrong? P.S. - I tried the devenv.exe /installvstemplates fix, which didn't change anything. Update: Here is the error captured in the SSIS package when you try to run it: Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.IO.FileNotFoundException: Could not load file or assembly 'edtFTPnetPRO, Version=6.3.1.20, Culture=neutral, PublicKeyToken=0dce1ad63760d80b' or one of its dependencies. The system cannot find the file specified. Where is it looking for this file? I tried copying it to the project direcory, the bin folder, and the C:\WINDOWS\Microsoft.NET\Framework\v2.0.nnnn folder, but it still can't find it, and it won't tell me where it's looking.

  • Selenium and Firefox 9's "Will you help improve Mozilla Firefox" popup

    - by Rup
    I'm trying to test a Java web app using Selenium 2.16.1. When Selenium opens Firefox, I see a band at the top of the page with message "Will you help improve Mozilla Firefox" For some reason this breaks selenium.click("id=submit"); selenium.waitForPageToLoad("60000"); which is trying to log in - it becomes a no-op, and the test fails because it's then expecting to have logged in. If I break on the click line and clear the 'will you help' band before continuing then the form submit succeeds. Is there a way to suppress this band from appearing? (I expect that would mean setting a property in Firefox's default profile - where do I find that?) Or is there a way to get Selenium to spot and dismiss this first? Thanks! I'm using Firefox 9.0.1. Solved - thanks Danny! Just in case it isn't clear from the answers and comments below: This was an issue with 2.16.1 and IMO the best solution is to upgrade to 2.17 or later.

  • Avoid the problem with BigDecimal when migrating to Java 1.4 to Java 1.5+

    - by romaintaz
    Hello, I've recently migrated a Java 1.4 application to a Java 6 environment. Unfortunately, I encountered a problem with the BigDecimal storage in a Oracle database. To summarize, when I try to store a "7.65E+7" BigDecimal value (76,500,000.00) in the database, Oracle stores in reality the value of 7,650,000.00. This defect is due to the rewritting of the BigDecimal class in Java 1.5 (see here). In my code, the BigDecimal was created from a double using this kind of code: BigDecimal myBD = new BigDecimal("" + someDoubleValue); someObject.setAmount(myBD); // Now let Hibernate persists my object in DB... In more than 99% of the cases, everything works fine. Except that in really few case, the bug mentioned above occurs. And that's quite annoying. If I change the previous code to avoid the use of the String constructor of BigDecimal, then I do not encounter the bug in my uses cases: BigDecimal myBD = new BigDecimal(someDoubleValue); someObject.setAmount(myBD); // Now let Hibernate persists my object in DB... However, how can I be sure that this solution is the correct way to handle the use of BigDecimal? So my question is to know how I have to manage my BigDecimal values to avoid this issue: Do not use the new BigDecimal(String) constructor and use directly the new BigDecimal(double)? Force Oracle to use toPlainString() instead of toString() method when dealing with BigDecimal (and in this case how to do that)? Any other solution? Environment information: Java 1.6.0_14 Hibernate 2.1.8 (yes, it is a quite old version) Oracle JDBC 9.0.2.0 and also tested with 10.2.0.3.0 Oracle database 10.2.0.3.0
