• How do I create an editable databound combo box in a DataGrid in WinForm

  - by signaldev235

  I have a noob question. I have a WinForm (.net 2.0 in VS 2008) on my from I have a DataGrid One of the fields in that datagrid is a combo box that is bound to a separate table. this works, but I am unable to edit or add, I cannot add a value that is not on the list. I am looking to create a lookup box for lack of a better term. The form is for Parts Order Entry In the data Grid Data Source is PartsOrder_table, the Work order Field is a int in the PartsOrder_table, and the combo box is bound to the WorkOrder_table. The WorkOPRder_Table has WorkOrd_ID int and WrkOrd nvarchar(10) the Combo Box Data Source is WorkOrd_Table Display Member is WorkOrd Value Member is WorkOrder_ID This works great with the problem that I cannot add or select anything not in WorkOrder_table. Any Help would be greatly appreciated. Thanks

• Using different validation rules based on user input.

  - by chiefanov

  I have a simple form: a combobox and a textbox. My combobox has 2 values: A and B. When value A is selected I want textbox to use a validation rule. When value B is selected there should be no validation rules applied to the textbox. I've read an article that has a solution and I'm trying to use it, but had no luck so far, and I think there might be a more elegant solution. Has anyone done anything like this before? Any ideas are highly appreciated.

• Problem removing a dynamic form field in jquery

  - by rshivers

  I'm trying to remove a dynamic form field by click a button. It will also subtract whatever values it had from the total amount from my calculation. This is the code: function removeFormField(id) { var id = $(id).attr("name"); $('#target1').text($("#total" + id).map(function() { var currentValue = parseFloat(document.getElementById("currentTotal").value); var newValue = parseFloat($("#total" + id).text()); var newTotal = currentValue - newValue; document.getElementById("currentTotal").value = newTotal; return newTotal; }).get().join()); $(id).remove(); } Okay, it will do the subtraction portion of the code with no problem, this issue is with the last line to remove the field. If I comment out the rest of the code it will work, but not with the rest of the code. I know this is something simple, yet I can't seem to wrap my mind around it. Can someone please help?

• Splitting a double in two, C#

  - by Stacey

  I'm attempting to use a double to represent a bit of a dual-value type in a database that must sometimes accept two values, and sometimes accept only one (int). So the field is a float in the database, and in my C# code, it is a double (since mapping it via EF makes it a double for some reason... ) So basically what I want to do .. let's say 2.5 is the value. I want to separate that out into 2, and 5. Is there any implicit way to go about this?

• Changing the context of a self-executing function

  - by TaylorMac

  This code is copied directly from: http://www.bennadel.com/blog/2264-Changing-The-Execution-Context-Of-Your-Self-Executing-Function-Blocks-In-JavaScript.htm // Set the singleton value to the return value of the self- // executing function block. var singleton = (function(){ // Declare a private variable. var message = "Stop playing with your context!"; this.getMessage = function(){ return( message ); }; // Return this object reference. return( this ); }).call( {} ); // alert the singleton message. alert( "Message:", singleton.getMessage()); ?My thought is that I can use this to better contain the variables and functions in my programs. However, when I try to run the code in a JSfiddle: http://jsfiddle.net/xSKHh/ It does not return the message. What am I missing?

• JavaScript not working with Chrome & Xampp!

  - by Anonymous

  Hi, I've been trying for a couple hours now to figure out why JavaScript wouldn't work. The code works, but here it is anyway. <script type="text/javascript"> function change(text) { document.f1.ta.value="Hi!"; } </script> <form name="f1"> <input type="textarea" id="ta"/> <input type="button" action='change("Hi!")'/> </form> When I click the button, it does nothing. When I write "document.f1.ta.value="Hi!";" in the Chrome's inspector console, it works. I am using XAMPP (for Windows) 1.7.3 Windows 7 Ultimate.

• Problem in populating a dictionary object using Enumerable.Range() (C#3.0)

  - by Newbie

  If I do for (int i = 0; i < appSettings.Count; i++) { string key = appSettings.Keys[i]; euFileDictionary.Add(key, appSettings[i]); } It is working fine. When I am trying the same thing using Enumerable.Range(0, appSettings.Count).Select(i => { string Key = appSettings.Keys[i]; string Value = appSettings[i]; euFileDictionary.Add(Key, Value); }).ToDictionary<string,string>(); I am getting a compile time error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. Any idea? Using C#3.0 Thanks

• How to create "lock" (stop updating of cells) in Excel?

  - by Oozi

  My question is pretty simple, but one to which I can't really find a solution myself. I use Excel quite frequently, but rarely the fancy stuff. Anyway, to the point: How do I create a dropmenu that will lock certain cells, rows or columns? (by lock I mean unable to change via hand and stops updating itself). Example: A1 = 5 B1 = A1 * 100 Can I "lock" the B1-cell, so that changing A1 will have no effect on B1 (Will remain at value 500)? I would preferably want to be able to "unlock" the cell as well, instead of simply making function into value. Is this possible? Thanks in advance!

• is the + in += on a Map a prefix operator of =?

  - by Steve

  In the book "Programming in Scala" from Martin Odersky there is a simple example in the first chapter: var capital = Map("US" -> "Washington", "France" -> "Paris") capital += ("Japan" -> "Tokyo") The second line can also be written as capital = capital + ("Japan" -> "Tokyo") I am curious about the += notation. In the class Map, I didn't found a += method. I was able to the same behaviour in an own example like class Foo() { def +(value:String) = { println(value) this } } object Main { def main(args: Array[String]) = { var foo = new Foo() foo = foo + "bar" foo += "bar" } } I am questioning myself, why the += notation is possible. It doesn't work if the method in the class Foo is called test for example. This lead me to the prefix notation. Is the + a prefix notation for the assignment sign (=)? Can somebody explain this behaviour?

• How to know if the argument that is passed to the function is a class, union or enum in c++?

  - by Narek

  I want to define an operator<< for all enums, to cout the value and print that it is an enum like this: code: enum AnyEnum{A,B,C}; AnyEnum enm = A; cout << enm <<endl; output: This is an enum which has a value equal to 0 I know a way of doing this with Boost library by using is_enum struct. But I don’t understand how it works. So that's why, in general, I am interested how to identify if the veriable is a class type, union type or an enum (in compile time).

• WPF binding: Doing a temperature converter app

  - by Bob

  Hi there, I'm doing a little app that basically has 2 text boxes. You'll enter Fahrenheit into TextBoxA and Celsius into TextBoxB. As the text changes in TextBoxA I want the equivalent Celsius value to be displayed in TextBoxB and vice versa. I can come up with a solution pretty easy for this but i'm trying to be a little clever. Is there a way to do it all in Xaml except for a Convert class that does the maths? So basically I want the TextChanged event of one textBox to pass in it's value into a Converter class that is evaluated and sent to the other TextBox and visa versa. Anyone know how I can achieve this ... and if it's possible at all?

• How do I provide a string with a list of values to an "IN" statement

  - by Degan

  I am creating a string that is a list of comma-delimitted values by looping through the selections in a CheckBoxList. I am able to display this value, so I know that it is creating what I expect. I am attempting to pass this list to an IN statment in a SELECT query: SelectCommand="SELECT ThisDate, DATEPART(dw, ThisDate) AS Expr1 FROM fbCalendar WHERE (ThisDate &gt;= @ThisDate) AND (ThisDate &lt;= @ThisDate2) AND (DATEPART(dw, ThisDate) IN (@TheseDays))" <asp:ControlParameter ControlID="Label1" Name="TheseDays" PropertyName="Text" Type="String" /> This works fine as long as there is only a single item selected, but selecting a second item fails with the message: Conversion failed when converting the nvarchar value '4,5' to data type int. However, I do not understand when this would be converted to an INT. I have tried many different formatting attempts (such as encapsulating the string in parenthesis (e.g. "(4,5)" ) for the SELECT query, but I have yet to find the right one to make this work. It seems like formatting is the problem, but perhaps I am missing something else.

• How to clear a textbox based on a checkbox using Javascript

  - by LoftyWofty

  I am trying to code in javascript (to avoid validation triggers at the server) to clear a text box if the checkbox associated with it is unchecked. I have this code ... <input type="checkbox" id="chkOTHER" onclick="document.getElementById('txtOtherFlag').value='';" /> <asp:TextBox ID="txtOtherFlag" runat="server" AutoPostBack="True" CausesValidation="True" ValidationGroup="ValidationGroup1"></asp:TextBox> The problem is the Javascript inside the checkbox is not triggering to remove the value in the text box. Even if this worked, it's incorrect as it would blank out the text box every time the checkbox is triggered whether it is checked or not. I need to resolve this in the client side only. Thank you

• How to combine two 32-bit integers into one 64-bit integer?

  - by Bei337

  I have a count register, which is made up of two 32-bit unsigned integers, one for the higher 32 bits of the value (most significant word), and other for the lower 32 bits of the value (least significant word). What is the best way in C to combine these two 32-bit unsigned integers and then display as a large number? In specific: leastSignificantWord = 4294967295; //2^32-1 printf("Counter: %u%u", mostSignificantWord,leastSignificantWord); This would print fine. When the number is incremented to 4294967296, I have it so the leastSignificantWord wipes to 0, and mostSignificantWord (0 initially) is now 1. The whole counter should now read 4294967296, but right now it just reads 10, because I'm just concatenating 1 from mostSignificantWord and 0 from leastSignificantWord. How should I make it display 4294967296 instead of 10?

• User's possibilities on site

  - by Lari13

  I want to build a system on the website, that allows users to do some things depend on their rating. For example I have rule for rating value X: 1 post in 3 days 10 comments in 1 day 20 votes in 2 days for rating value Y, rule may be following: 3 post in 1 day 50 comments in 1 day 30 votes in 1 day Each night I recalculate users' ratings, so I know what each user is able to do. Possibilities don't sum or reset on each rating's recalculation. One more important thing is that admin can fill concrete user's possibilities at any time. What is optimal database (MySQL) structure for desired? I can count what concrete user has done: SELECT COUNT(*) FROM posts WHERE UserID=XXX AND DateOfPost >= 'YYY' SELECT COUNT(*) FROM comments WHERE UserID=XXX AND CommentOfPost >= 'YYY' But how can I do admin filling possibilities in this case?

• Switching back into the middle of a function in Actionscript

  - by J.Ded.

  I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards. The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

• Storing acceleration values in Objective-C/Cocoa?

  - by ASchlaep

  Hi all, I'm writing for the iPhone and I'm trying to measure the time between maximum accelerations. Imagine you've attached your iPhone to an oscillating spring. What I want to do is measure the frequency of the oscillation. The way I am going about doing this is storing a certain number acceleration values (updated 20 times per second) in an NSMutableArray and comparing the current acceleration value with previous acceleration values. How do I add each updated acceleration value to the NSMutableArray and at the same time delete values from the back of the array as I don't need them any more? Thanks in advance!

• [iphone] use NSString in other method?!

  - by user134282

  It's really embarrassing but i stuck on it for two hours of trial and error. I declared an NSString in the interface as: NSString *testString; Then i made a property and synthesized it. I allocate it in viewDidLoad with: testString = [[NSString alloc] initWithFormat:@"thats my value: %i", row]; If i want to get the value of the string in another method it always return (null). So the string is empty, but why? how do i make it accessible for every function inside of one class? So i don't want to make a global var just a "global variable inside the class" It's really confusing because as long as i code i never ran into this problem :( thanks a lot for helping me!

• A pointer member variable having different values

  - by Rohan Prabhu

  Ok, to begin with, this is my code: HyperSprite::HyperSprite() { _view = 0; } void HyperSprite::publish(QGraphicsView* view) { _view = view; } void HyperSprite::getKFrame() { if(_view != 0) { qDebug()<<(void*)_view; } } Now, if I call HyperSprite::getKFrame() from within main(), I get the output: 0xbf8ffb84 I have a TCP server, which requires this QGraphicsView* variable. So whenever a new connection is made, HyperSprite::getKFrame() is called. However, whenever I make a connection to my server, this is the output: 0x1e425ff I honestly don't understand this. Shouldn't the value of a member remain same throughout? Why is the pointer value changing? As is obvious, whenever I try to use the _view pointer to access any of its members, a Segmentation Fault occurs. I tried using QSharedPointer, but it also results in the same problem. The data of the QSharedPointer automatically changes. Why is this happening?
