• Delphi - OnKeyPress occurs before TStringGrid updates cell with new character

  - by JMTyler

  Coding in Delphi, attaching an OnKeyPress event handler to a TStringGrid: The OnKeyPress event fires before the grid cell that the user is typing into has actually updated its value with the key that has been pressed. This is obviously a problem, when I want to know what the contents of that cell are at this moment, as in, as the user modifies it. The "hacked" solution is simple, if you're not considering every detail: just grab the value from the cell and, since the OnKeyPress event comes along with a Key parameter, append that value to the end - now you have the current value of the cell! False. What if the user has selected all the text in the cell (ie: "foo") and they are now typing 'b'. Since they selected the text, it will be erased and replaced with the letter 'b'. However, the value of the cell will still display as "foo" in OnKeyPress, and the value of Key will be 'b', so the above logic would lead the application to conclude that the cell now contains "foob", which we know is not true. So. Does anybody know how to get around this problem? Is there a way to make OnKeyPress react after the grid's contents have been updated, or perhaps a way to force an update at the start of the handler? I am desperately avoiding the use of the OnKeyUp event here, so any suggestions aside from that would be greatly appreciated.

• Issue reading in a cell from Excel with Apache POI

  - by Nick

  I am trying to use Apache POI to read in old (pre-2007 and XLS) Excel files. My program goes to the end of the rows and iterates back up until it finds something that's not either null or empty. Then it iterates back up a few times and grabs those cells. This program works just fine reading in XLSX and XLS files made in Office 2010. I get the following error message: Exception in thread "main" java.lang.NumberFormatException: empty String at sun.misc.FloatingDecimal.readJavaFormatString(Unknown Source) at java.lang.Double.parseDouble(Unknown Source) at the line: num = Double.parseDouble(str); from the code: str = cell.toString(); if (str != "" || str != null) { System.out.println("Cell is a string"); num = Double.parseDouble(str); } else { System.out.println("Cell is numeric."); num = cell.getNumericCellValue(); } where the cell is the last cell in the document that's not empty or null. When I try to print the first cell that's not empty or null, it prints nothing, so I think I'm not accessing it correctly.

• jQuery validate plugin against custom jQueryUI datePickers

  - by Enrique

  I have some datePickers I've customized these so they show only month and year This is the code to create them jQuery("input[name*='fechauso']").each(function() { jQuery(this).datepicker({ changeMonth: true, changeYear: true, showButtonPanel: true, dateFormat: 'MM yy', constrainInput: true, showOn: 'button', buttonText: 'Seleccionar...', onClose: function(dateText, inst) { var month = jQuery("#ui-datepicker-div .ui-datepicker-month :selected").val(); var year = jQuery("#ui-datepicker-div .ui-datepicker-year :selected").val(); jQuery(this).datepicker('setDate', new Date(year, month, 1)); } }); }); Now I've added a custom validator method (using plugin) to check this: If user didn't select a date using the button, field is empty, so the custom validator method should fire. This doesn't happen. Here is the custom validate method jQuery.validator.addMethod("isEmpty", function(value, element) { return (value == ''); }, "Must select a date with the button besides control"); jQuery("#ct_2_fechauso").rules("add", { required: "#campotilde_psico:checked", isEmpty: true }); The problem is that even if I select a date, it always ask me to select a date again. datePicker fields should be readonly

• Why do Firefox and Opera ignore max-width inside of display: table-cell?

  - by brad

  The following code displays correctly in Chrome or IE (the image is 200px wide). In Firefox and Opera the max-width style is ignored completely. Why does this happen and is there a good work around? Also, which way is most standards compliant? Note One possible work around for this particular situation is to set max-width to 200px. However, this is a rather contrived example. I'm looking for a strategy for a variable width container. <!doctype html> <html> <head> <style> div { display: table-cell; padding: 15px; width: 200px; } div img { max-width: 100%; } </style> </head> <body> <div> <img src="http://farm4.static.flickr.com/3352/4644534211_b9c887b979.jpg" /> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec facilisis ante, facilisis posuere ligula feugiat ut. Fusce hendrerit vehicula congue. at ligula dolor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. leo metus, aliquam eget convallis eget, molestie at massa. </p> </div> </body> </html> [Update] As stated by mVChr below, the w3.org spec states that max-width does not apply to inline elements. I've tried using div img { max-width: 100%; display: block; }, but it does not seem to correct the issue.

• Android custom view - setting it to take up max space available but no more

  - by Rich

  I have a custom View class in my app that I'm using in xml layouts. Wherever I'm using this view in my xml, I don't want it to stretch it's container, but I want it to fill out whatever space is available. Here's an example to make it a little clearer. I have a LinearLayout set to horizontal orientation with my custom view followed by a TextView. The TextView is going to stretch the LinearLayout so that it takes up the space it needs and no more. I want my custom view to take up the vertical space that the TextView has made available. Let's say the TextView ends up being 50px tall because of it's contents. The LinearLayout is thus stretched to about this height (not taking into account any margins or padding), so I just want the view to know it can stretch to that height and not "push on" its container. Without overriding and of the measurement methods of the base class (onMeasure, etc) my View is actually stretching to take up as much space as possible. I have already played around with wrap_content and fill_parent a bunch, so I'm assuming I need to do something in one of the View class' measure methods.

• How can I unit test my custom validation attribute

  - by MightyAtom

  I have a custom asp.net mvc class validation attribute. My question is how can I unit test it? It would be one thing to test that the class has the attribute but this would not actually test that the logic inside it. This is what I want to test. [Serializable] [EligabilityStudentDebtsAttribute(ErrorMessage = "You must answer yes or no to all questions")] public class Eligability { [BooleanRequiredToBeTrue(ErrorMessage = "You must agree to the statements listed")] public bool StatementAgree { get; set; } [Required(ErrorMessage = "Please choose an option")] public bool? Income { get; set; } .....removed for brevity } [AttributeUsage(AttributeTargets.Class)] public class EligabilityStudentDebtsAttribute : ValidationAttribute { // If AnyDebts is true then // StudentDebts must be true or false public override bool IsValid(object value) { Eligability elig = (Eligability)value; bool ok = true; if (elig.AnyDebts == true) { if (elig.StudentDebts == null) { ok = false; } } return ok; } } I have tried to write a test as follows but this does not work: [TestMethod] public void Eligability_model_StudentDebts_is_required_if_AnyDebts_is_true() { // Arrange var eligability = new Eligability(); var controller = new ApplicationController(); // Act controller.ModelState.Clear(); controller.ValidateModel(eligability); var actionResult = controller.Section2(eligability,null,string.Empty); // Assert Assert.IsInstanceOfType(actionResult, typeof(ViewResult)); Assert.AreEqual(string.Empty, ((ViewResult)actionResult).ViewName); Assert.AreEqual(eligability, ((ViewResult)actionResult).ViewData.Model); Assert.IsFalse(((ViewResult)actionResult).ViewData.ModelState.IsValid); } The ModelStateDictionary does not contain the key for this custom attribute. It only contains the attributes for the standard validation attributes. Why is this? What is the best way to test these custom attributes? Thanks

• WPF Calling a custom command on a custom control (from a viewmodel?)

  - by user190615

  I want to take a snap of the visual tree of a custom wpf control when the user clicks a button in a toolbar. The control is bound to a viewmodel. I have a BitmapSource dp in the custom control holding the snapped image which is bound to a property on my VM. The BitmapSource dp on the control is updated via a custom command on the control. I've tied the toolbar button's command to call the controls command which updates the BitmapSource. Now the problem is the end result I want is when the user clicks the button, the control updates its image and then the vm offers to save this image. I cant wrap my mind around an mvvm way of doing this. One inelegant solution is that control fires an event after the image is updated which is routed to the viewmodel as a command(command behavior) but then if i want to do something else with the image on some other button click, all the commands bound to the events will fire. All thoughts appreciated. EDIT The command on the control is a RoutedCommand and the commands in my vm are Prism delegate commands.

• Custom model in ASP.NET MVC controller: Custom display message for Date DataType

  - by Rita

  Hi I have an ASP.NET MVC Page that i have to display the fields in customized Text. For that I have built a CustomModel RequestViewModel with the following fields. Description, Event, UsageDate Corresponding to these my custom Model has the below code. So that, the DisplayName is displayed on the ASP.NET MVC View page. Now being the Description and Event string Datatype, both these fields are displaying Custom DisplayMessage. But I have problem with Date Datatype. Instead of "Date of Use of Slides", it is still displaying UsageDate from the actualModel. Anybody faced this issue with DateDatatype? Appreciate your responses. Custom Model: [Required(ErrorMessage="Please provide a description")] [DisplayName("Detail Description")] [StringLength(250, ErrorMessage = "Description cannot exceed 250 chars")] // also need min length 30 public string Description { get; set; } [Required(ErrorMessage="Please specify the name or location")] [DisplayName("Name/Location of the Event")] [StringLength(250, ErrorMessage = "Name/Location cannot exceed 250 chars")] public string Event { get; set; } [Required(ErrorMessage="Please specify a date", ErrorMessageResourceType = typeof(DateTime))] [DisplayName("Date of Use of Slides")] [DataType(DataType.Date)] public string UsageDate { get; set; } ViewCode: <p> <%= Html.LabelFor(model => model.Description) %> <%= Html.TextBoxFor(model => model.Description) %> <%= Html.ValidationMessageFor(model => model.Description) %> </p> <p> <%= Html.LabelFor(model => model.Event) %> <%= Html.TextBoxFor(model => model.Event) %> <%= Html.ValidationMessageFor(model => model.Event) %> </p> <p> <%= Html.LabelFor(model => model.UsageDate) %> <%= Html.TextBoxFor(model => model.UsageDate) %> <%= Html.ValidationMessageFor(model => model.UsageDate) %> </p>

• Custom Sorting on Custom Field in Django

  - by RotaJota

  In my app, I have defined a custom field to represent a physical quantity using the quantities package. class AmountField(models.CharField): def __init__(self, *args, **kwargs): ... def to_python(self, value): create_quantities_value(value) Essentially the way it works is it extends CharField to store the value as a string in the database "12 min" and represents it as a quantities object when using the field in a model array(12) * min Then in a model it is used as such: class MyModel(models.Model): group = models.CharField() amount = AmountField() class Meta: ordering = ['group', 'amount'] My issue is that these fields do not seem to sort by the quantity, but instead by the string. So if I have some objects that contain something like {"group":"A", "amount":"12 min"} {"group":"A", "amount":"20 min"} {"group":"A", "amount":"2 min"} {"group":"B", "amount":"20 min"} {"group":"B", "amount":"1 hr"} they end up sorted something like this: >>> MyModel.objects.all() [{A, 12 min}, {A, 2 min}, {A, 20 min}, {B, 1 hr}, {B, 20 min}] essentially alphabetical order. Can I give my custom AmountField a comparison function so that it will compare by the python value instead of the DB value?

• ASP.NET MVC Custom Routing Long Custom Route not Clicking in my Head

  - by percent20

  I have spent several hours today reading up on doing Custom Routing in ASP.NET MVC. I can understand how to do any type of custom route if it expands from or is similar/smaller than the Default Route. However, I am trying figure out how to do a route similar to: /Language/{id}/Question/{id}/ And what I would like, too, is similar to how SO works. Something like: /Language/{id}/Arabic/Question/{ID}/Some-Question-Title Where "Arabic" and "Some-Question-Title" can be almost anything because what really matters is the ID's Am I going beyond what can be done with the extended URL past the language ID?

• Subterranean IL: Custom modifiers

  - by Simon Cooper

  In IL, volatile is an instruction prefix used to set a memory barrier at that instruction. However, in C#, volatile is applied to a field to indicate that all accesses on that field should be prefixed with volatile. As I mentioned in my previous post, this means that the field definition needs to store this information somehow, as such a field could be accessed from another assembly. However, IL does not have a concept of a 'volatile field'. How is this information stored? Attributes The standard way of solving this is to apply a VolatileAttribute or similar to the field; this extra metadata notifies the C# compiler that all loads and stores to that field should use the volatile prefix. However, there is a problem with this approach, namely, the .NET C++ compiler. C++ allows methods to be overloaded using properties, like volatile or const, on the parameters; this is perfectly legal C++: public ref class VolatileMethods { void Method(int *i) {} void Method(volatile int *i) {} } If volatile was specified using a custom attribute, then the VolatileMethods class wouldn't be compilable to IL, as there is nothing to differentiate the two methods from each other. This is where custom modifiers come in. Custom modifiers Custom modifiers are similar to custom attributes, but instead of being applied to an IL element separately to its declaration, they are embedded within the field or parameter's type signature itself. The VolatileMethods class would be compiled to the following IL: .class public VolatileMethods { .method public instance void Method(int32* i) {} .method public instance void Method( int32 modreq( [mscorlib]System.Runtime.CompilerServices.IsVolatile)* i) {} } The modreq([mscorlib]System.Runtime.CompilerServices.IsVolatile) is the custom modifier. This adds a TypeDef or TypeRef token to the signature of the field or parameter, and even though they are mostly ignored by the CLR when it's executing the program, this allows methods and fields to be overloaded in ways that wouldn't be allowed using attributes. Because the modifiers are part of the signature, they need to be fully specified when calling such a method in IL: call instance void Method( int32 modreq([mscorlib]System.Runtime.CompilerServices.IsVolatile)*) There are two ways of applying modifiers; modreq specifies required modifiers (like IsVolatile), and modopt specifies optional modifiers that can be ignored by compilers (like IsLong or IsConst). The type specified as the modifier argument are simple placeholders; if you have a look at the definitions of IsVolatile and IsLong they are completely empty. They exist solely to be referenced by a modifier. Custom modifiers are used extensively by the C++ compiler to specify concepts that aren't expressible in IL, but still need to be taken into account when calling method overloads. C++ and C# That's all very well and good, but how does this affect C#? Well, the C++ compiler uses modreq(IsVolatile) to specify volatility on both method parameters and fields, as it would be slightly odd to have the same concept represented using a modifier or attribute depending on what it was applied to. Once you've compiled your C++ project, it can then be referenced and used from C#, so the C# compiler has to recognise the modreq(IsVolatile) custom modifier applied to fields, and vice versa. So, even though you can't overload fields or parameters with volatile using C#, volatile needs to be expressed using a custom modifier rather than an attribute to guarentee correct interoperability and behaviour with any C++ dlls that happen to come along. Next up: a closer look at attributes, and how certain attributes compile in unexpected ways.

• Aggregating Excel cell contents that match a label [migrated]

  - by Josh

  I'm sure this isn't a terribly difficult thing, but it's not the type of question that easily lends itself to internet searches. I've been assigned a project for work involving a complex spreadsheet. I've done the usual =SUM and other basic Excel formulas, and I've got enough coding background that I'm able to at least fudge my way through VBA, but I'm not certain how to proceed with one part of the task. Simple version: On Sheet 1 I have a list of people (one on each row, person's name in column A), on sheet 2 I have a list of groups (one on each row, group name in column A). Each name in Sheet 1 has its own row, and I have a "Data Validation" dropdown menu where you choose the group each person belongs to. That dropdown is sourced from Sheet 2, where each group has a row. So essentially the data validation source for Sheet 1's "Group" column is just "=Sheet2!$a1:a100" or whatever. The problem is this: I want each group row in Sheet 2 to have a formula which results in a list of all the users which have been assigned to that group on Sheet 1. What I mean is something the equivalent of "select * from PeopleTab where GROUP = ThisGroup". The resulting cell would just stick the names together like "Bob Smith, Joe Jones, Sally Sanderson" I've been Googling for hours but I can't think of a way to phrase my search query to get the results I want. Here's an example of desired result (Dash-delimited. Can't find a way to make it look nice, table tags don't seem to work here): (Sheet 1) Bob Smith - Group 1 (selected from dropdown) Joe Jones - Group 2 (selected from dropdown) Sally Sanderson - Group 1 (selected from dropdown) (Sheet 2) Group 1 - Bob Smith, Sally Sanderson (result of formula) Group 2 - Joe Jones (result of formula) What formula (or even what function) do I use on that second column of sheet 2 to make a flat list out of the members of that group?

• Compiled code spreadsheet-like cell management? (auto-updating)

  - by proGrammar

  Okay so I am fully aware how spreadsheets manage cells, they build dependency graphs where when one cell changes it tells all the other cells that are dependent on it that it changed. So they can from there update. How they update I think involves either re-evaluating the formulas stored as strings, or re-evaluating the abstract syntax tree which I think is stored differently and might be faster. Something like that. What I'm looking to do is manage a few variables in my code so I don't have to update them in the correct way, which would be a nightmare. But I also want it much faster than spreadsheets. And since I'm not looking for any functionality as great as are in these spreadsheets, I just figured from that thought point that there has to be a way to have a very fast implementation of this functionality. Especially since I don't have to modify cells after compiling unless that would be an option. I'm very new to programming so I have no idea. One example might be to have a code-generator that generates code that does this for me. But I have no clue what the generated code would look like. Specifically, how exactly would variables inform others that they need to update, and what do those variables do to update? I'm looking for any kind of ideas. Programming is not my job but nonetheless I was hoping to have some kind of system like this that would greatly help me with some stuff. Of course I have been programming plenty lately so I can still program. I just don't have the full scope on things. I'm looking for any kind of ideas, thank you very much in advance! Also, please help me with the tags. I know C# and Java mainly and I'm hoping to implement this in either of those languages and I'm hoping this can stay in those tags. Forcing this into some kind of spreadsheet tag wouldn't be accurate.

• How can I assign custom icons to folders?

  - by Frank Souza

  How do I assign custom icons to folders, as well as the default folders Desktop, Downloads, Music, etc.? I know that one way is to assign the properties of folders, but I want to assign icons in the same way that are assigned the default folders, so the custom icons will also appear in the Nautilus bookmarks. I've also seen this question custom icon in "Places" menu <<, but that is not what I seek. UPDATE My main intention is this: I want the markers to display custom icons like the dolphin. I know it's possible, because the folder "Desktop", "Documents", "Music" has its own custom icons in bookmarks. How?

• Should custom data elements be stored as XML or database entries?

  - by meteorainer

  There are a ton of questions like this, but they are mostly very generalized, so I'd like to get some views on my specific usage. General: I'm building a new project on my own in Django. It's focus will be on small businesses. I'd like to make it somewhat customizble for my clients so they can add to their customer/invoice/employee/whatever items. My models would reflect boilerplate items that all ModelX might have. For example: first name last name email address ... Then my user's would be able to add fields for whatever data they might like. I'm still in design phase and am building this myself, so I've got some options. Working on... Right now the 'extra items' models have a FK to the generic model (Customer and CustomerDataPoints for example). All values in the extra data points are stored as char and will be coerced/parced into their actual format at view building. In this build the user could theoretically add whatever values they want, group them in sets and generally access them at will from the views relavent to that model. Pros: Low storage overhead, very extensible, searchable Cons: More sql joins My other option is to use some type of markup, or key-value pairing stored directly onto the boilerplate models. This coul essentially just be any low-overhead method weather XML or literal strings. The view and form generated from the stored data would be taking control of validation and reoganizing on updates. Then it would just dump the data back in as a char/blob/whatever. Something like: <datapoint type='char' value='something' required='true' /> <datapoint type='date' value='01/01/2001' required='false' /> ... Pros: No joins needed, Updates for validation and views are decoupled from data Cons: Much higher storage overhead, limited capacity to search on extra content So my question is: If you didn't live in the contraints impose by your company what method would you use? Why? What benefits or pitfalls do you see down the road for me as a small business trying to help other small businesses? Just to clarify, I am not asking about custom UI elements, those I can handle with forms and template snippets. I'm asking primarily about data storage and retreival of non standardized data relative to a boilerplate model.

• .Net Custom Configuration Section and Saving Changes within PropertyGrid

  - by Paul

  If I load the My.Settings object (app.config) into a PropertyGrid, I am able to edit the property inside the propertygrid and the change is automatically saved. PropertyGrid1.SelectedObject = My.Settings I want to do the same with a Custom Configuration Section. Following this code example (from here http://www.codeproject.com/KB/vb/SerializePropertyGrid.aspx), he is doing explicit serialization to disk when a "Save" button is pushed. Public Class Form1 'Load AppSettings Dim _appSettings As New AppSettings() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click _appSettings = AppSettings.Load() ' Actually change the form size Me.Size = _appSettings.WindowSize PropertyGrid1.SelectedObject = _appSettings End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click _appSettings.Save() End Sub End Class In my code, my custom section Inherits from ConfigurationSection (see below) Question: Is there something built into ConfigurationSection class that does the autosave? If not, what is the best way to handle this, should it be in the PropertyGrid.PropertyValueChagned? (how does the My.Settings handle this internally?) Here is the example Custom Class that I am trying to get to auto-save and how I load into property grid. Dim config As System.Configuration.Configuration = _ ConfigurationManager.OpenExeConfiguration( _ ConfigurationUserLevel.None) PropertyGrid2.SelectedObject = config.GetSection("CustomSection") Public NotInheritable Class CustomSection Inherits ConfigurationSection ' The collection (property bag) that contains ' the section properties. Private Shared _Properties As ConfigurationPropertyCollection ' The FileName property. Private Shared _FileName As New ConfigurationProperty("fileName", GetType(String), "def.txt", ConfigurationPropertyOptions.IsRequired) ' The MasUsers property. Private Shared _MaxUsers _ As New ConfigurationProperty("maxUsers", _ GetType(Int32), 1000, _ ConfigurationPropertyOptions.None) ' The MaxIdleTime property. Private Shared _MaxIdleTime _ As New ConfigurationProperty("maxIdleTime", _ GetType(TimeSpan), TimeSpan.FromMinutes(5), _ ConfigurationPropertyOptions.IsRequired) ' CustomSection constructor. Public Sub New() _Properties = New ConfigurationPropertyCollection() _Properties.Add(_FileName) _Properties.Add(_MaxUsers) _Properties.Add(_MaxIdleTime) End Sub 'New ' This is a key customization. ' It returns the initialized property bag. Protected Overrides ReadOnly Property Properties() _ As ConfigurationPropertyCollection Get Return _Properties End Get End Property <StringValidator( _ InvalidCharacters:=" ~!@#$%^&*()[]{}/;'""|\", _ MinLength:=1, MaxLength:=60)> _ <EditorAttribute(GetType(System.Windows.Forms.Design.FileNameEditor), GetType(System.Drawing.Design.UITypeEditor))> _ Public Property FileName() As String Get Return CStr(Me("fileName")) End Get Set(ByVal value As String) Me("fileName") = value End Set End Property <LongValidator(MinValue:=1, _ MaxValue:=1000000, ExcludeRange:=False)> _ Public Property MaxUsers() As Int32 Get Return Fix(Me("maxUsers")) End Get Set(ByVal value As Int32) Me("maxUsers") = value End Set End Property <TimeSpanValidator(MinValueString:="0:0:30", _ MaxValueString:="5:00:0", ExcludeRange:=False)> _ Public Property MaxIdleTime() As TimeSpan Get Return CType(Me("maxIdleTime"), TimeSpan) End Get Set(ByVal value As TimeSpan) Me("maxIdleTime") = value End Set End Property End Class 'CustomSection
