• Get Excel.Application object from Process or hwnd in .NET

  - by Abiel

  In C# I am trying to get an instance of an Excel.Application object from a Process object. This seems like it should be really simple yet I cannot figure it out and cannot find an example. To repeat, I have a System.Diagnostics.Process object that I know refers to a running Excel instance. I now need to recover a Microsoft.Office.Interop.Excel.Application object that refers to the process so that I can go about manipulating the Excel application from C#. In case it makes it any simpler, I also have the HWND id and window text associated with the active Excel window. Thanks.

• How to debug macruby?

  - by Dan

  Hi, I've encountered an inconsistent bug with MacRuby and have no idea how to go about debugging this. If anyone could help would be great. I don't know if this is due to my own code or is it a bug in the MacRuby framework. I have a feeling it's my own code, something about over-retaining a piece of memory and hence the garbage collection failed. This is the error from Xcode. Thanks. CSV Wizard(30245,0x7fff704f7ca0) malloc: resurrection error for object 0x20199da20 while assigning {conservative-block}[196608](0x302360060)[117616] = Array[64](0x20199da20) garbage pointer stored into reachable memory, break on auto_zone_resurrection_error to debug CSV Wizard(30245,0x103781000) malloc: garbage block 0x20199da20(Array[64]) was over-retained during finalization, refcount = 1 This could be an unbalanced CFRetain(), or CFRetain() balanced with -release.

• multi column sorting of datagrid view:

  - by Bi

  I have a datagridview in a windows form with 3 columns: Serial number, Name and Date-Time. The Name column will always have either of the two values: "name1" or "name2". I need to sort these columns such that the grid displays all the rows with name values in a specific order (first display all the "name1" rows and then all the "name2" rows). Within the "name1" rows, I want the rows to be sorted by the Date-Time. Please note programmatically, all the 3 columns are strings. For example, if I have the rows: 01 |Name1 | 2010-05-05 10:00 PM 02 |Name2 | 2010-05-02 08:00 AM 03 |Name2 | 2010-05-01 08:00 AM 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM needs to be sorted as 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM 01 |Name1 | 2010-05-05 10:00 PM 03 |Name2 | 2010-05-01 08:00 AM 02 |Name2 | 2010-05-02 08:00 AM I am not sure how to go about using the below: myGrid.Sort(.....,ListSortDirection.Ascending)

• How to reset all the values after completion of the game, before starting it again ?

  - by srikanth rongali

  I have writing a small shooting game in cocos2d. Winning the game is to eliminate all the 10 enemies. After that end screen comes showing 'You Won' and 'Play Again'. If I go for 'Play Again' option the game is starting from where I need. But, the problem is that the game is continuing from previously ended state. I mean it is not starting from enemy 1 again instead it is just showing the end of 10 enemy. I think I have to reset all the values before pushing the scene. But should I reset all the values I have used or there is any other way ? Thank You.

• VS2005 project has dependency that is not built

  - by Eyal

  I have VS2005 solution that contains many projects and dependencies (some C++, some C#) - in the past it compiled successfully. when I rebuild all the solution it fails on a project claiming dll is missing (dll that was needed to built before according to dependency). the thing is that from time to time it fails on random project (not all the time the same project). I'm not sure it is meaningful but I see in output console Deleting intermediate and output files for project doesn't VS2005 go according to "Project Build Order" and ReBuild every project starting with its dependencies?

• Copy and Store LPTSTR in class causes crash

  - by Jake M

  I am attempting to copy a LPTSTR and store that string as a member variable in an object. But my attempts to copy the LPTSTR seem to fail and when I go to access/print the value of the copied LPTSTR I get a program crash. Is it possible to copy a LPTSTR and store it in my class below or is it better to just use a TCHAR*? class Checkbox { private: LPTSTR text; HWND hwnd; public: Checkbox(HWND nHwnd, LPTSTR nText) { lstrcpy(checkText, text); } void print() { // Causes a crash MessageBox(hwnd, text, text, MB_OK); } };

• [Simple] Beginner AJAX script not working, stuck on opening XMLHttpRequest

  - by Julian H. Lam

  Hopefully, this question isn't too juvenile to ask - but here goes: I'm trying to learn AJAX, and I'm stuck on a simple content-fetch. Here is my code: request = getHTTPObject(); function useHttpResponse() { if (request.readyState == 4) { document.getElementById("p").innerHTML = request.responseText; } } function update_p() { request.open("GET",content.html,true); request.onreadystatechange = useHttpResponse; } getHTTPObject is correctly defined, and returns a proper XMLHttpObject. As you probably guessed from the excerpt, the element I am trying to update is id'd "p". It calls the script correctly when a button is clicked, no problem there. The script seems to stop at line 8, at request.open. There's no error, and the script silently ignores anything afterward. I don't think I've missed anything, but of course, I probably did. Where did I go wrong? Thanks!

• problem in interceptor executing before action in struts2

  - by vivmal

  Hi All, I am working on struts2. I have an interceptor that executes before my action claas. Now when I submit on a jsp page control goes to interceptor and after some processing there the control goes to action class. This complete flow is running well.

Can anyone tell me how to find solution for these two points. Thanks in advance.

• If handcoded webpage displays the same as WYSIWYG generated page, what did I gain? Can I compete wit

  - by CrazyJugglerDrummer

  My friend uses DreamWeaver to create web pages and doesn't know any HTML at all. I know HTML inside and out and can hand code from the ground up. But our web pages look similar and he can get paid for his WYSIWYG generated sites. What have I gained from learning HTML and hand-coding? Can I compete with people using DreamWeaver or other WYSIWYG editors? I know that for something like JavaScript or PHP the only way to go is to hand-code the whole thing yourself, no tools can do that for you, but is HTML in the same position?

• dynamic silverlight content

  - by Jeremy

  I am starting a silverlight project where I have tests for students to complete. I want to have some sort of framework so I can build the tests and store them in a database, delivering the content dynamically so I can continually develop new types of tests without having to re-deply the application. The content will have to be more than just xaml, as there may need to be some logic to determine if answers are correct, or to do some random generation of questions. I'm looking for suggestions on how to go about building a framework that supports this. Are there some best practices, or examples? Should each test type just be a seperate silverlight control, or should I use 1 silverlight "container" application that can display dynamic content?

• What is a class outlet and where is it?

  - by chrish

  I am trying to learn iPhone development and someone passed along the website www.appsamuck.com. On Day 1, the tutorial instructs the developer We need to reference the label in our code so we can update the label * In the document window "File's Owner" * Click: Tools->Idenity Inspector * In the inspector click the + under "Class Outlets" * Change myOutlet1 to "countdownLabel" * Change id to UILabel * Click enter to make sure they commit I really don't want to get hung up on this, but I can't find "Class Outlets" either when creating a new project from scratch or opening the zipped source code project. Is this just a difference in versions of Interface Builder? Where did it go?

• Nhibernate ValueType Collection as delimited string in DB

  - by JWendel

  Hi I have a legacy db that I am mapping with Nhibernate. And in several locations a list och strigs or domain objects are mapped as a delimited string in the database. Either 'string|string|string' in the value type cases and like 'domainID|domainID|domainID' in the references type cases. I know I can create a dummy property on the class and map to that fields but I would like to do it in a more clean way, like when mapping Enums as their string representation with the EnumStringType class. Is a IUserType the way to go here? Thanks in advance /Johan

I have a table with 1 long row (1000 pixels) and one single column, how do i go about creating a method whereby when the mouse cursor is on the leftmost side of the cell, a variable, lets say X is set to 0, the further right the mouse cursor moves in the cell, the value of X increases. I know that sounds like a strange question but im working on a project where this type of functionality is desired. Is there a javascript method to create this feature? Thanks for any help.

• Great computer-science speeches

  - by sub

  I've looked into some questions here where the "best" programming books are listed and then thought why there isn't a question concerning speeches yet. I think that speeches or presentations from developers or even creators of programming languages which were or are heavily used at some point are particulary interesting. One of my favorite speeches was recommended to me by someone here on SO: The future of C# I also like Guido van Rossum's speeches but he sometimes seems pretty nervous. Another in my opinion good presentation would be the Google tech talk about Go. Which (recorded) programming presentations/speeches are worth watching? edit: Made this a community wiki as the answer would probably be a pretty long list.

• I'm not sure if I should use a redirect

  - by Joe

  Hi there, I have an affiliate link on my webpage. When you click on the link it follows the href value which is as follows: www.site_name.com/?refer=my_affiliate_id This would be fine, except that the site offers no tracking for the ads, so I can't tell how many clicks I am getting. I could easily implement my own tracking by changing the original link href value to a php script which increments some click stats in a database and then redirects the user to the original page. But I have read some articles that say that using redirects may be seen by google as a sign of 'blackhat' techniques and they might rank me lower, unindex my site or even hurt the site that I'm redirecting too. Does anybody know if this is true, or have any idea of the best way I could go about this? Many thanks in advance Joe

  I am trying to get list of reviews for specific changeset using FishEye REST API.

• Which SOA architecture is most appropriate for a Java application?

  - by Robert Greiner

  I am currently working on a pretty large Java 6 application where we are looking to split some of our functionality out into a service oriented architecture. It seems that the primary SOA framework for the application space is OSGi and I have been looking into Felix and Knopplerfish but I wanted to make sure that this isn't my only option. Does it make sense to use an actual web service protocol for our application like SOAP, even though we are not building a web app? Is this even acceptable? Have any of you used an implementation of OSGi (Felix, etc.) with your desktop application? if so, how did it go? Do you know of anything better? We're all pretty new to SOA here so any help would be greatly appreciated.

• Manipulating binary data in Python

  - by Dominic Bou-Samra

  I am opening up a binary file like so: file = open("test/test.x", 'rb') and reading in lines to a list. Each line looks a little like: '\xbe\x00\xc8d\xf8d\x08\xe4.\x07~\x03\x9e\x07\xbe\x03\xde\x07\xfe\n' I am having a hard time manipulating this data. If I try and print each line, python freezes, and emits beeping noises (I think there's a binary beep code in there somewhere). How do I go about using this data safely? How can I convert each hex number to decimal?

• Sharepoint: How to obtain the current site/web/list properly

  - by driAn

  Hi all What is the best way to obtain the current site/web/list ? Option 1 - Reusing existing objects SPSite site = SPContext.Current.Site; SPweb web = SPContext.Current.Web; SPList list = SPContext.Current.List; Option 2 - Creating new objects SPSite site = new SPSite(SPContext.Current.Site.ID); // dispose me SPweb web = site.OpenWeb(SPContext.Current.Web.ID); // dispose me SPList list = web.Lists[SPContext.Current.List.ID]; I experienced problems when using option 1 in some situations. Since then I chose the 2nd option and it worked fine so far. What is your opinion on this? I is generally better to go with option 2? Other suggestions?

• Creating a new project from a project skeleton using git

  - by asciitaxi

  In order to get a new django project up and running faster, I'd like to maintain a separate "project skeleton" on which I base all my new projects. It would be great if, as I improved the skeleton, I could bring those improvements into my active projects. How can I accomplish this with git? So, maybe in my remote git repository machine I would have 1 repo for each project and one for the skeleton? proj-A-repo proj-B-repo skeleton-repo If I want to create a new proj-C locally based on the skeleton, then push my local changes up to the remote server in a new repo called proj-C-repo, how might I do this? I've read through quite a bit of git documentation, but I'm confused about how to go about this. Do I need to clone the skeleton, or create an empty repo and then track a remote branch, or something else?

• Custom User Management for Google App Engine Java

  - by Gopi

  I am using GAE Java for a multi-user application. There are multiple users with different roles. Each user can login, do some operations and logout. The business restricts me from using Google User Service and I need to implement my own for authentication and session management. Can anyone please share with me how should I go about implementing my own user management? I have read its very tricky to implement own user management. Any pointers in terms of best approaches/ design / existing frameworks if any ? I could see some similar posts but they are for python.

• Magento Product Details Image Size

  - by Jason

  Magento 1.4 Default Product Details image size is 265x265. All of our product images will be probably 2x taller than wide, and even if we pad them to make them square 265 will be too small to see detail in the image, so we'd like to make the image taller. I found the media.phtml file How would we go about modifying this file/Magento so that the product details page image is 265W x 530H. This looks like the code that displays the image. <p class="product-image"> <?php $_img = '<img src="'.$this->helper('catalog/image')->init($_product, 'image')->resize(265).'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'" />'; echo $_helper->productAttribute($_product, $_img, 'image'); ?> </p> Thanks
