  • Getting the time interval between typing characters in a TextBox, in C#

    - by sama
    I have a form that has a TextBox and a Label and I want to get the time of the first character entered in the textbox. Then if the user enters more than ten charcaters, the time between the first charcter entered and the tenth charcter entered is displayed in the label. Can any one help me please? I'm using C# Here is the code but I cannot complete it and I have many things that need to be written but I don't know how to continue. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Threading; namespace n { public partial class Form1 : Form { int count=0; public Form1() { InitializeComponent(); } private void textBox1_TextChanged(object sender, EventArgs e) { DateTime t1 = new DateTime();// the time when entering the first charcter DateTime t2 = new DateTime(); t2 = System.DateTime.Now - t1; int index = textBox1.SelectionStart; Point p; p = textBox1.GetPositionFromCharIndex(index); Thread t = new Thread(counttext); t.Start(); label1.Text = "t2"; } private int counttext() { while (textBox1.Text.Length < 10) { count++; if (count == 10) return count; } } } }

    - by RayMartinsHair
    Hi, If I apply a style from the SL 3.0 Toolkit to my application the built in SL 3.0 data validation errors are not displayed on the application edit forms. If I removed the code that applies the toolkit style to the application the SL 3.0 data validation errors appear as per normal SL 3.0 behaviour? Has anyone else come across this problem????? Any help is always appreciated. Cheers Adam

  • IE7/IE8 javascript drop down menu used to redirect not working

    - by Robbiegod
    The error I see from IE7/IE8 in Jquery v1.7.2 and v.1.7.1 - i tried both: SCRIPT438: Object doesn't support property or method 'apply' My Code: <form> <select id="stateD" OnChange="showState()"> <option value="none" selected="selected">==========</option> <option value="http://www.google.com">google</option> <option value="http://www.yahoo.com">Yahoo</option> </select> </form> My Javascript - I have this pasted just below the webform: <script type="text/javascript"> function showState(){ oStates = document.getElementById("stateD"); var jLink = $("#stateD :selected").val(); if (jLink == undefined || jLink == "none" ){ alert("Please Select a State"); } else{ document.location.href=jLink}; } </script> I'm not using 2 libraries so i don't get why its having a problem. All that is supposed to happen is you select a url from the drop down menu and it auto sends you to that url that is in the value of the option tag. Works everywhere else, not sure why IE has to be such a jerk today. I'd post a url but i can't at the moment. its private. has anyone encountered this issue before?

  • Support clicking a link, but sending a POST (vs GET) to the server, without Ajax?

    - by xyld
    I'm thinking this isn't exactly possible, but maybe I'm wrong. I'm simply torn between those who believe that only POST requests should modify data on the server and people that relax the rule and allow GET requests to modify data. Take this situation. Say you have a table, each row is a row in the database. I'd like to allow them to delete the row via a fancy "X" icon as the very last <td></td> element in the row. AFAIK, the only way to send a POST to the server is via a form. But do I really stuff an entire form into the last <td></td> element just to do a POST? Or should I cheat and use an <a href=...></a> tag that sends a GET request? You may be thinking "Do both! Send a POST AND use the <a ...></a> tag! Use fancy javascript + xhr!" And I'll say, oh? And how will that degrade in a zero javascript environment? Maybe we've reached a point when it doesn't make sense to worry about gracefully degrading? I'm not sure. You tell me? I'm new to web development, but I understand most of the concepts involved.

  • error while updating a database in ASP.NET

    - by Viredae
    I am having trouble updating an SQL database, the problem is not that it doesn't update at all, but that particular parameters are being updated while the others are not. here is the code for updating the parameters: string EditRequest = "UPDATE Requests SET Description = @Desc, BJustif = @Justif, Priority = @Priority, Requested_System = @Requested, Request_Status = @Stat WHERE"; EditRequest += " Req_ID=@ID"; SqlConnection Submit_conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["DBConn"].ConnectionString); SqlCommand Submit_comm = new SqlCommand(EditRequest, Submit_conn); Submit_comm.Parameters.AddWithValue("@ID", Request.QueryString["reqid"]); Submit_comm.Parameters.AddWithValue("@Desc", DescBox.Text); Submit_comm.Parameters.AddWithValue("@Justif", JustifBox.Text); Submit_comm.Parameters.AddWithValue("@Priority", PriorityList.SelectedValue); Submit_comm.Parameters.AddWithValue("@Requested", RelatedBox.Text); Submit_comm.Parameters.AddWithValue("@Stat", 1); Submit_conn.Open(); Submit_comm.ExecuteNonQuery(); Submit_comm.Dispose(); Submit_comm = null; Submit_conn.Close(); get_Description(); Page.ClientScript.RegisterStartupScript(this.GetType(), "Refresh", "ReloadPage();", true); this function is called by a button on a pop-up form which shows the parameters content that is being changed in a text box which is also used to submit the changes back to the database, but when I press submit, the parameters which are displayed on the form don't change, I can't find any problem wit the code, even though I've compared it to similar code which is working fine. In case you need to, here is one of the text boxes I'm using to display and edit the content: <asp:TextBox ID="JustifBox" TextMode="MultiLine" runat="server" Width="250" Height="50"></asp:TextBox> What exactly is wrong with the code?

  • Windows Forms application C# | Sending Tweet

    - by Andrew Craswell
    I've been able to get my Twitter web app working just fine, but I've recently decided to add Tweeting functionality from a Windows Form, but I'm having no luck sending tweets. No errors are thrown or anything. Mind looking over my code? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using TweetSharp; namespace TwitterAdvirtiser { public partial class Form1 : Form { private string cKey = "xxx"; private string cSecret = "xxx"; private string oToken = "xxx"; private string aToken = "xxx"; public Form1() { InitializeComponent(); OnStart(); } private void OnStart() { //Authenticate with Twitter TwitterService service = new TwitterService(cKey, cSecret); service.AuthenticateWith(oToken, aToken); service.SendTweet("testing"); } } } It seems like I'm authenticating just fine, I can walk through debug mode and see all my details in the TwitterUser structure, and yet my tweets never show up on my feed. Whats up? By the way, I'm using Visual Studios 2010, and .NET 4.0. I have verified that the oToken and aToken strings have my developer tokens.

  • Why is FBJS dropping my 'onclick' attribute from this input element?

    - by Chris Barnhill
    When I include an 'onClick' attribute in setInnerXTHML() like this: var innerHtml = '<span>Build Track: Select a city where track building should begin'+ '<div id="action-end">'+ '<form>'+ '<input type="button" value="End Track Building" id="next-phase" onClick="moveTrainAuto();" />'+ '</form>'+ '</div></span>'; actionPrompt.setInnerXHTML(innerHtml); var btn = document.getElementById('next-phase'); btn.addEventListener('click', 'moveTrainAuto'); The 'onClick' gets dropped. I know this from inspecting the element with Firebug. This is what it reveals: <input id="app148184604666_next-phase" type="button" value="End Track Building"/> Here is the function called for onClick: function moveTrainAuto(evt) { debugger; ajax = new Ajax(); ajax.responseType = Ajax.JSON; ajax.ondone = function(data) { debugger; if(data.code == 'UNLOAD_CARGO') { unloadCargo(); } else if (data.code == 'MOVE_TRAIN_AUTO') { moveTrainAuto(); } else if (data.code == 'TURN_END') { turnEnd(); } else { /* handle error */ } } ajax.post(baseURL + '/turn/move-trains-auto'); } As you can see, I've tried both 'onClick' and 'addEventListener'. Neither works. Any ideas?

  • What is the best approach to use different CFLAGS for the same source files?

    - by evilsocket
    Hello, i need to build the same source tree twice, 1 - with normal cflags to build the project binary 2 - with cflags plus -fPIC to build a static library that would be some sort of SDK to develop project dynamic modules. Using only one Makefile, what is the best approach to accomplish this? It would be nice to do some sort of : all: $(OBJECTS) lib_rule: $(OBJECTS) CFLAGS += -fPIC .cpp.o: $(CC) -c $< -o $@ $(CFLAGS) But obviously it can't be done. Thanks

  • How to show users the reason for a message being bounced or rejected by Postfix?

    - by Ross Bearman
    A user would like to be able to view a web page showing any emails that a Postfix server has either been unable to send, or unable to receive. For example if the user was supposed to receive an email from a third party but it hasn't arrived, they'd be able to check the web page and see a list of emails rejected by Postfix, along with a clear reason as to why. I've been unable to find an existing application that offers this functionality. Does anyone know of any, or is the best way forward to write a script that parses the log and display the results?

  • Windows 8 Google Contacts Sync doesn't sync custom fields

    - by Nishant
    I installed Windows 8 Pro a couple days ago. In the in-built "People" app, since there were options to sync contacts with several third party services like Facebook, Linkedin etc., I wanted to sync my Google contacts to the People app. The sync was successful and all my contacts migrated properly. However, the age old problem of custom fields not syncing between Google/Apple/Windows apps is still present. If a field label in my Google contacts is 'iPhone', it doesn't sync! Nor do any other custom fields except 'home' or 'work' with numbers. Is there a solution to this or any other workaround?

  • many-to-many-to-many, incl alignment of data from diff sources

    - by JefeCoon
    Re-factoring dbase to support many:many:many. At the second and third levels we need to preserve end-user 'mapping' or aligning of data from different sources, e.g. Order 17 FirstpartyOrderID => aha LineItem_for_BigShinyThingy => AA-1 # maps to 77-a LineItem_for_BigShinyThingy => AA-2 # maps to 77-b, 77-c LineItem_for_LittleWidget => AA-x # maps to 77-zulu, 77-alpha, 99-foxtrot LineItem_for_LittleWidget => AA-y # maps to 77-zulu, 99-foxtrot LineItem_for_LittleWidget => AA-z # maps to 77-alpha ThirdpartyOrderID => foo LineItem_for_BigShinyThingy => 77-a LineItem_for_BigShinyThingy => 77-b LineItem_for_BigShinyThingy => 77-c LineItem_for_LittleWidget => 77-zulu LineItem_for_LittleWidget => 77-alpha ThirdpartyOrderID => bar LineItem_for_LittleWidget => 99-foxtrot Each LineItem has daily datapoints reported from its own source (Firstparty|Thirdparty). In our UI & app we provide tools to align these, then we'd like to save them into the cleanest possible schema for querying, enabling us to diff the reported daily datapoints, and perform other daily calculations (which we'll store in the dbase also, fortunately that should be cake once we've nailed this). We need to map related [firstparty|thirdparty]line_items which have their own respective datapoints. We'll be using the association to pull each line_items collection of datapoints for summary and discrepancy calculations. I'm considering two options, std has_many,through x2 --or-- possibly (scary) ubermasterjoin table OptionA: order<<-->> order_join_table[id,order_id,firstparty_order_id,thirdparty_order_id] <<-->>line_item order_join_table[firstparty_order_id]-->raw_order[id] order_join_table[thirdparty_order_id]-->raw_order[id] raw_order-->raw_line_items[raw_order_id] line_item<<-->> line_item_join[id,LI_join_id,firstparty_LI,thirdparty_LI <<-->>raw_line_items line_item_join[firstparty_LI]-->raw_line_item[id] line_item_join[thirdparty_LI]-->raw_line_item[id] raw_line_item<<-->>datapoints = we rely upon join to store all mappings of first|third orders & line_items = keys to raw_* enable lookup of these order & line_item details = concerns about circular references and/or lack of correct mapping logic, e.g order--line_item--raw_line_items vs. order--raw_order--raw_line_items OptionB: order<<-->> join_master[id,order_id,FP_order_id,TP_order_id,FP_line_item_id,TP_line_item_id] join_master[FP_order_id & TP_order_id]-->raw_order[id] join_master[FP_line_item_id & TP_line_item_id]-->raw_line_item[id] = every combo of FP_line_item + TP_line_item writes a record into the join_master table = "theoretically" queries easy/fast/flexible/sexy At long last, my questions: a) any learnings from painful firsthand experience about how best to implement/tune/optimize many-to-many-to-many relationships b) in rails? c) any painful gotchas (circular references, slow queries, spaghetti-monsters) to watch out for? d) any joy & goodness in Rails3 that makes this magically easy & joyful? e) anyone written the "how to do many-to-many-to-many schema in Rails and make it fast & sexy?" tutorial that I somehow haven't found? If not, I'll follow up with our learnings in the hope it's helpful.. Thanks in advance- --Jeff

  • CSS to specify positions over a scanned document

    - by itsols
    I'm trying to write the CSS rules to position text over a scanned document. Reason: The document is a pre-printed form. I am trying to position the text on-screen so that it relates to the 'spaces' on the actual form. Issue: Although I position the values using centimeters, they don't seem to get aligned with the ones on the actual page. I can see this misalignment since my scanned image is in the background of the page. What I've tried: I used a ruler to physically measure the locations and specify them with CSS. But on-screen, it doesn't tally. I used the scanned image to position the CSS values. Then the printout is not correct. I even scaled the scanned page using Inkscape to the exact dimensions in centimeters and took into account all margins, etc... What I need: I am trying to correctly show the output values on-screen AND have them print in the correct manner as well. I know that using two CSS sheets (one for print) is an option. But I'm developing this program away from where the actual printing is to be done. So is there a convenient way of matching the exact screen locations with those on the actual/final prinout? Thanks!

  • Win Server 2003 - Task Scheduler - Tasks with GUI and Services

    - by august_month
    I need to run excel macro daily. I scheduled it with Windows Scheduler and it worked fine until I had to change my password. I wonder if it's possible to have a task scheduled without a password? As alternative we have third party scheduling software, but this software cannot launch excel. The tech support said that since excel has gui and scheduling software runs as service with "Allow to interact to Desktop" disabled, it cannot launch excel. Also tech support mentioned that "Allow to interact to Desktop" is not supported as of Vista. I totally trust tech support guy, I just need a work around that would make my network administrator and me happy. Regards.

  • How to cache code in PHP?

    - by Janis Peisenieks
    I am creating a custom form building system, which includes various tokens. These tokens are found using Regular Expressions, and depending on the type of toke, parsed. Some require simple replacement, some require cycles, and so forth. Now I know, that RegExp is quite resource and time consuming, so I would like to be able to parse the code for the form once, creating a php code, and then save the PHP code, for next uses. How would I go about doing this? So far I have only seen output caching. Is there a way to cache commands like echo and cycles like foreach()? Because of misunderstandings, I'll create an example. Unparsed template data: Thank You for Your interest, [*Title*] [*Firstname*] [*Lastname*]. Here are the details of Your order! [*KeyValuePairs*] Here is the link to Your request: [*LinkToRequest*]. Parsed template: "Thank You for Your interest, <?php echo $data->title;?> <?php echo $data->firstname;?> <?php echo $data->lastname;?>. Here are the details of Your order! <?php foreach($data->values as $key=>$value){ echo $key."-".$value }?> Here is the link to Your request: <?php echo $data->linkToRequest;?>. I would then save the parsed template, and instead of parsing the template every time, just pass the $data variable to the already parsed one, which would generate an output.

  • Best practice how to store HTML in a database column

    - by tbrandao
    I have an application that modifies a table dynamically, think spreadsheet), then upon saving the form (which the table is part of) ,I store that changed table (with user modifications) in a database column named html_Spreadhseet,along with the rest of the form data. right now I'm just storing the html in a plain text format with basic escaping of characters... I'm aware that this could be stored as a separate file, the source table (html_workseeet) already is. But from a data handling perspective its easier to save the changed html table to and from a column so as to avoid having to come up with a file management strategy (which folder will this live in, now must include folder in backups, security issues now need to apply to files, how to sync db security with file system etc.), so to minimize these issues I'm only storing the ... part in the database column. My question is should I gzip the HTML , maybe use JSON, or some other format to easily store and retrieve the HTML from the database column, what is the best practice to store HTML content in a datbase? Or just store it as I currently am as an escaped text column?
