• COM on Windows7 and Visual Studio

  - by vikasde

  I registered a COM dll (under administrator) using regsvr32, which I want to use in Visual Studio 2008 (under administrator) for my project in Windows 7. Now, when I try to use the interfaces and classes from the COM, then I can't see any of the methods. When I use the object browser to view the COM classes, then I can see that they are all empty. However when I use the same COM on windows XP using VS2008, then all methods are suddenly available. Does anybody know why this is happening and how to get this working under Windows 7?

• MySQL ignores the NOT NULL constraint

  - by Marga Keuvelaar

  I have created a table with NOT NULL constraints on some columns in MySQL. Then in PHP I wrote a script to insert data, with an insert query. When I omit one of the NOT NULL columns in this insert statement I would expect an error message from MySQL, and I would expect my script to fail. Instead, MySQL inserts empty strings in the NOT NULL fields. In other omitted fields the data is NULL, which is fine. Could someone tell me what I did wrong here? I'm using this table: CREATE TABLE IF NOT EXISTS tblCustomers ( cust_id int(11) NOT NULL AUTO_INCREMENT, custname varchar(50) NOT NULL, company varchar(50), phone varchar(50), email varchar(50) NOT NULL, country varchar(50) NOT NULL, ... date_added timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (cust_id) ) ; And this insert statement: $sql = "INSERT INTO tblCustomers (custname,company) VALUES ('".$customerName."','".$_POST["CustomerCompany"]."')"; $res = mysqli_query($mysqli, $sql);

• Calling Html.ActionLink in a custom HTML helper

  - by Sylvain

  I am designing a custom HTML helper and I would like to execute Html.ActionLink to provide dynamic URL generation. namespace MagieMVC.Helpers { public static class HtmlHelperExtension { public static string LinkTable(this HtmlHelper helper, List<Method> items) { string result = String.Empty; foreach (Method m in items) { result += String.Format( "<label class=\"label2\">{0}</label>" + System.Web.Mvc.Html.ActionLink(...) + "<br />", m.Category.Name,m.ID, m.Name); } return result; } } } Unfortunately Html.ActionLink is not recognized in this context whatever the namespace I have tried to declare. As a generic question, I would like to know if it is possible to use any existing standard/custom Html helper method when designing a new custom helper. Thanks.

How can I correctly build this .Net project "ServiceLauncher"?

• How can I get jQuery UI's Draggable and Sortable functions to work on the iPhone?

  - by Damovisa

  I have a page that uses JQuery UI; in particular the Sortable interaction. The page works fine for desktop web browsers with mice, however I can't get the drag-drop functionality to work on Mobile Safari on the iPhone. Any dragging action simply scrolls the page. The functionality on my page is extremely similar to the Sortable Empty-Lists demo on the JQuery UI site. This page also doesn't work on the iPhone. Is there any way to get the drag-drop functions working on the iPhone?

• How do I hook up a custom tab bar build in IB to a UINavigationController Object instanced in XCODE?

  - by David Hsu

  What I did to create the custom NAV BAR: 1. Created an empty XIB and added a view with class UINavigationController. 2. Under the view I added the navigation bar and a left and right button onto the nav bar. 3. Control drag from "File Owner" to "View" Inside my class where I call the modal view navigation controller: SignupViewController *addController = [[SignupViewController alloc] initWithNibName:@"SignupViewController" bundle:nil]; // Create the navigation controller and present it modally. UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController]; navigationController.navigationBar = ///WHAT SHOULD GO HERE? [self presentModalViewController:navigationController animated:YES]; Thank in advance!

• Using resource values as layout attributes (config.xml)

  - by synic

  Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations. Given the config.xml: <resources> <string name="config_somePadding">50dip</string> </resources> How would I reference this to use as the layout_height in a layout xml file? @string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string. In the sdk, they use an integer for animation duration. They reference it like this: android:duration="@android:integer/config_longAnimTime". Is there a way to use values that aren't integers in the layout_height attribute?

• What does Visual Studio 2008 do when I add an assembly reference?

  - by tk-421

  When I add a reference to an assembly (living in the GAC) to web.config in an ASP.NET project, what does Visual Studio do? [This is related to an earlier question pertaining to BusinessObjects: http://stackoverflow.com/questions/2379615/ ] When I add "CrystalDecisions.Enterprise" and "CrystalDecisions.Enterprise.Framework" to the assemblies element in web.config, VS thinks long and hard about it, locking me out for a couple of minutes while it scrutinizes the newcomers. What is it doing during this time? I Googled this but came up empty. I can make some educated guesses (IntelliSense integration, perhaps?) but would ideally like to find some documentation describing exactly what's going on. Ultimately I'm hoping to learn why these BO references are making VS take several minutes to open my projects (I struck out on the SAP forums).

• A very basic auto-expanding list/array

  - by MainMa

  Hi, I have a method which returns an array of fixed type objects (let's say MyObject). The method creates a new empty Stack<MyObject>. Then, it does some work and pushes some number of MyObjects to the end of the Stack. Finally, it returns the Stack.ToArray(). It does not change already added items or their properties, nor remove them. The number of elements to add will cost performance. There is no need to sort/order the elements. Is Stack a best thing to use? Or must I switch to Collection or List to ensure better performance and/or lower memory cost?

• Html.DropDownListFor() in Mozilla Firefox

  - by Andrey

  I'm rendering a drop down list using Html.DropDownListFor() extension. The markup I get is as follows: select id="NationalityId" name="NationalityId" option value="" /option option selected="selected" value="1"Estonian /option option value="2"Russian /option option value="3"Ukranian /option option value="4"Belorussian /option option value="5"Swedish /option option value="6"Dutch /option /select As you can see, option with value==1 is selected. But in Firefox 3.6.3 it doesn't display as selected, empty string (first option - value == "") is displayed instead. IE7 and Chrome render the page right - the option is selected. Does anybody know what is going on? How do I get this around?

• How to add custom hooks to controllers in ASP.NET MVC2

  - by Adrian

  Hi, I've just started a new project in ASP.net 4.0 with MVC 2. What I need to be able to do is have a custom hook at the start and end of each action of the controller. e.g. public void Index() { *** call to the start custom hook to externalfile.cs (is empty so does nothing) ViewData["welcomeMessage"] = "Hello World"; *** call to the end custom hook to externalfile.cs (changes "Hello World!" to "Hi World") return View(); } The View then see welcomeMessage as "Hi World" after being changed in the custom hook. The custom hook would need to be in an external file and not change the "core" compiled code. This causes a problem as with my limited knowledge ASP.net MVC has to be compiled. Does anyone have any advice on how this can be achieved? Thanks

• [Objective-C] Primitive question, (void) init method.

  - by user354289

  Hi, I have a question in Objective-C. I'm using init method Apple recommended style. - (id)initMyClass: (int)a { if (self = [super init]) { // a... } return self; } Init method returns own object pointer. Then, if the object will not be refered from any objects, can empty return method(void) be better? - (void)initMyClass: (int)a { if ([super init] != nil) { // a... } } I want to know about that, if init method doesn't return self, what problem will occur?

• xval get message from resource file

  - by Rob

  I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this? Below the code which should make the relation to the resourcefile en specify the error when the field is left empty. [Property] [Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")] public virtual Double ShippingCost { get; set; }

• MySQL: Blank row in table after LOAD DATA INFILE

  - by Tom

  Hi, I'm uploading a large amount of data from a CSV (I'm doing it via MySQL Workbench): LOAD DATA INFILE 'C:/development/mydoc.csv' INTO TABLE mydatabase.mytable CHARACTER SET utf8 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r'; However, I'm noticing that it keeps adding an empty line full of nulls/zeros after the last record. I'm guessing it's because of the "LINES TERMINATED" command. However, I need that to load the data in correctly. Is there some way around this / some better SQL to avoid the blank row in the table? Thanks

• Accessing the value of a Richfaces calendar during validation.

  - by JBristow

  I am trying to validate a field based on another field's value. <h:form id="item"> <s:validateAll/> <h:selectBooleanCheckbox id="selected" value="#{bean.selected}" validator="selectedValidator"/> <rich:calendar id="startDate" value="#{bean.startDate}"/> </h:form> However, inside my validator. public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException { UIInput startComp = (UIInput) context.getViewRoot().findComponent("item:startDate"); if(value != null && value) { // Check value of startComp and throw exception if null or empty. } } The component startComp resolves, but has no value. Where is the value that appears in the text box of the richfaces calendar component?

• Does the chunk of the System.Collections.Concurrent.Partitioner need to be thread safe?

  - by Scott Chamberlain

  I am working with the Parallel libraries in .net 4 and I am creating a Partitioner and the example shown in the MSDN only has a chunk size of 1 (every time a new result is retrieved it hits the data source instead of the local cache. The version I am writing will pull 10000 SQL rows at a time then feed the rows from the cache until it is empty then pull another batch. Each partition in the Partitioner has its own chunk. I know every time I call to the IEnumerator in from the SQL data-source that needs to be thread safe but for use in a Parallel.ForEach do I need to make every call to the cache for the chunking thread safe?

• Echo autoincrement id doubt

  Hi, can I print the id, even if it's autoincrement ? Because the way I'm doing I'm using an empty variable for id. $id= ""; mysql_connect(localhost,$username,$password); @mysql_select_db($database) or die ("Não conectou com a base $database"); mysql_query("INSERT INTO table1(id,...) VALUES ('".$id."',....)") or die(mysql_error()); mysql_close(); echo "Your id is :"; echo "".$id; I'm trying to print the id, but it's coming blank. I checked the table and there's an id number there. How can I print it then at? Thanks for the attention

• string extension method - Not available through WebMethod

  - by Peter Bridger

  I've written a simple extension method for a web project, it sits in a class file called StringExtensions.cs which contains the following code: using System; using System.Collections.Generic; using System.Linq; using System.Web; /// <summary> /// Useful extensions for string /// </summary> static class StringExtensions { /// <summary> /// Is string empty /// </summary> /// <param name="value"></param> /// <returns></returns> public static bool IsEmpty(this string value) { return value.Trim().Length == 0; } } I can access this extension method from all the classes I have within the App_Code directory. However I have a web page called JSON.aspx that contains a series of [WebMethods] - within these I cannot see the extension method - I must be missing something very obvious!

• How do you add a row to a databound datagridview using the datagridview in the gui?

  - by IsaacB

  Hi guys, I've bound a datagridview to a collection of objects. It's giving me a null reference exception when I try to add a new row to a collection (empty or otherwise) using the gui. More specifically, when there is a write event it does this. How can I override the behavior of the write event and manually add all of the columns contents to the object collection? I could disable the add new row feature and make an add button, but the built in datagridview row add looks so much more slick.

• How to debug a process using Visual Studio?

  - by Ian Boyd

  If an application† crashes: i hit "Debug" and Visual Studio is my currently registered Just-In-Time (JIT) debugger: Visual Studio appears, but there's no way to debug anything: i do not see any disassembly. i do not see any symbols i do not see reconstructed source code from reflection i do not see any registers the call stack is empty Other JIT debugger products are able to show disassembly, but they are either command-line based (Debugging Tools for Windows), or do not support symbols (OllyDbg, Delphi). Additionally, my question is about debugging using Visual Studio, since i already have it installed, and is already my registered JIT. How do you debug a program using Visual Studio? Alternatively: has anyone written a graphical debugger that supports the Microsoft symbol server? † not, necessarily, written in Visual Studio Edit: Changes title to process rather than application, since the latter somehow implies "my application."

• Returning partial address matches and mismatch position using L2S or SQL

  - by peter3

  I need to implement a method that takes an address split up into individual parts and returns any matching items from an address table. If no matches are found, I want to be able to return a value indicating where it failed. Each input param has a corresponding field in the table. The signature would look something like this: List<Address> MatchAddress(string zipCode, string streetName, string houseNumber, string houseLetter, string floor, string appartmentNo, out int mismatchPosition) { // return matching addresses // if none found, return the position where it stopped matching // zipCode is position 0, appartmentNo is position 5 // // an empty param value indicates "don't check" } I know I can construct the method such that I start with all the parameters, execute the query and then remove param by param (from the right side) until either a match is found or I run out of parameters, but can I construct a query that is more effective than that, i.e minimizing the number of calls to the db, maybe even as a single call?
