• Releasing from development into production in maven

  - by Bruce

  Hi all, I'm confused about the use of maven in development and production environments - I'm sure it's something simple that I'm missing. Grateful for any help.. I set up maven inside eclipse on my local machine and wrote some software. I really like how it's made things like including dependent jars very easy. So that's my development environment. But now I want to release the project to production on a remote server. I've searched the documentation, but I can't figure out how it's supposed to work or what the maven best practice is.. Are you supposed to: a) Also be running maven on your production environment, and upload all your files to your production environment and rebuild your project there? (Something in me baulks at the idea of rebuilding 'released' code on the production server, so I'm fairly sure this isn't right..) b) use mvn:package to create your jar file and then copy that up to production? (But then what of all those nice dependencies? Isn't there a danger that your tested code is now going to be running against different versions of the dependent jars in the production environment, possibly breaking your code? Or missing a jar..?) c) Something else that I'm not figuring out.. Thanks in advance for any help!

• How to create a desktop shortcut to a website with website logo as icon?

  - by Wbdvlpr

  Hi I need a solution which allows users to create a desktop shortcut to a website, preferably with website logo as shortcut icon. There are ways users can create shortcut such as drag drop favicon or right click create new shortcut etc. This works but also creates the shortcut with default IE icon on windows. I am trying to avoid this method for this icon and some other reasons. I thought of creating a website-title.URL file, and tell users to download and save file to their desktop, again this works but doesn't solve the icon problem as the website logo (.ico) has to be at local disk and at a pre-specified location [IconFile=path]. I was wondering if it is possible to create a some sort of installer or windows application which users can download from the website. Once its executed by user, it creates this .URL file on user desktop which have IconFile path pre-specified, and copy the website-logo.ico at path specified in .URL file etc. So my questions are - Is it possible to create such a solution? What programming languages can be used to achieve this? Can this installer/app be made to work on non-windows machines as well? From developments point of view how big project it is? if I have to hire a programmer to do this. Please let me know if you need more information. Thanks

• How to create anroid to send to work in my place?

  - by aj-sin-dhal

  Hi I would like to create a life like android/robot to send to work in my place. Requirements 1) People should not be able to tell the difference between me and the android. My first attempt may not be perfect but I can tell people that its my twin that was dropped on its head while we were growing up. 2) Should have the same weight as me so it won't crush small children if it falls over. By small children I mean those above 7 years old. Those below 7 can easily be crushed by a normal human adult so it is not important to consider that special case. 3) Should run on linux. I have a tight budget and cannot afford to pay for any propreitary operating system. Will consider writing my own operating system if this is the best way to go. I am reading "The design of the unix operating system" by Maurice J. Bach currently. That should be useful. I also have an old copy of the dragon book. What other books should I read? I would like to finish this by monday if possible. I don't like working on mondays. I have made a start and have picked some clothes and shoes for my android worker. Any help will be appreciated. This is a serious question. AJ

• How to avoid concurrent execution of a time-consuming task without blocking?

  - by Diego V

  I want to efficiently avoid concurrent execution of a time-consuming task in a heavily multi-threaded environment without making threads wait for a lock when another thread is already running the task. Instead, in that scenario, I want them to gracefully fail (i.e. skip its attempt to execute the task) as fast as possible. To illustrate the idea considerer this unsafe (has race condition!) code: private static boolean running = false; public void launchExpensiveTask() { if (running) return; // Do nothing running = true; try { runExpensiveTask(); } finally { running = false; } } I though about using a variation of Double-Checked Locking (consider that running is a primitive 32-bit field, hence atomic, it could work fine even for Java below 5 without the need of volatile). It could look like this: private static boolean running = false; public void launchExpensiveTask() { if (running) return; // Do nothing synchronized (ThisClass.class) { if (running) return; running = true; try { runExpensiveTask(); } finally { running = false; } } } Maybe I should also use a local copy of the field as well (not sure now, please tell me). But then I realized that anyway I will end with an inner synchronization block, that still could hold a thread with the right timing at monitor entrance until the original executor leaves the critical section (I know the odds usually are minimal but in this case we are thinking in several threads competing for this long-running resource). So, could you think in a better approach?

• Printing in Silverlight 4

  - by Number8

  Hello, We have an application structured roughly like this: <Grid x:Name="LayoutRoot"> <ScrollViewer> <Canvas x:Name="canvas"> <StackPanel> < Button /><Slider /><Button /></StackPanel> <custom:Blob /> <custom:Blob /> <custom:Blob /> </Canvas> </ScrollViewer> </Grid> Each Blob consists of 1 or more rectangles, lines, and text boxes; they are positioned anywhere on the canvas. If I print the document using the LayoutRoot: PrintDocument pd = new PrintDocument(); pd += (s, pe) => { pe.PageVisual = LayoutRoot; }; pd.Print("Blobs"); ... it is like a print-screen -- the scrollbars, the sliders, the blobs that are visible -- are printed. If I set PageVisual = canvas, nothing is printed. How can I get all the blob objects, and just those objects, to print? Do I need to copy them into another container, and give that container to PageVisual? Can I use a ViewBox to make sure they all fit on one page? Thanks for any pointers....

• Does IE completely ignore cache control headers for AJAX requests?

  - by Joshua Hayworth

  Hello there, I've got, what I would consider, a simple test web site. A single page with a single button. Here is a copy of the source I'm working with if you would like to download it and play with it. When that button is clicked, it creates a JavaScript timer that executes once a second. When the timer function is executed, An AJAX call is made to retrieve a text value. That text value is then placed into the DOM. What's my problem? IE Caching. Crack open Task Manager and watch what happens to the iexplorer.exe process (IE 8.0.7600.16385 for me) while the timer in that page is executing. See the memory and handle count getting larger? Why is that happening when, by all accounts, I have caching turned off. I've got the jQuery cache option set to false in $.ajaxSetup. I've got the CacheControl header set to no-cache and no-store. The Expires header is set to DateTime.Now.AddDays(-1). The headers are set in both the page code-behind as well as the HTTP Handler's response. Anybody got any ideas as to how I could prevent IE from caching the results of the AJAX call? Here is what the iexplorer.exe process looks like in ProcessMonitor. I believe that the activity shown in this picture is exactly what I'm attempting to prevent.

• jQuery - Compatibility Problem with Internet Explorer 7 and Opera

  - by Marius

  Hello there, I have this counter which counts + 1 every time somebody shares content from the site. When it happens, the social icon that was clicked will bounce. It works in Firefox,Chrome, IE8, and Opera, however the bouncing animation is wrong in opera. $.fn.countExternal = function(animSpeed, num) { // for each counter this.each(function(){ // select all the digit containers var span = $(this).children(); // count the num of digit containers var len = $(span).length; // get the current count u = $(span).text(); // copy variable and add increment(s) v = num + ''; // foreach digit container... for (i=v.length - 1; i >= 0; i--) { // ...check which digits are not affected by the increment(s) if (v.charAt(i) == u.charAt(i)) { break; } } // slice from the total number of digit containers the digits containers which needs updating. slce = len - (v.length - (i + 1)) var updates = $(span).slice(slce); // loop through each digit container and fade out ... $(updates).fadeTo(animSpeed, 0,function(){ $(updates).each(function(index){ f = i + 1 + index; // ...then pick the right digit and update the digit... $(this).text(v.charAt(f)); // ...before fading back in. Cycle complete. $(this).fadeTo(animSpeed, 1); }); }); }); }; }) (jQuery); Demo (NSFW) is here (look underneath the social sharing icons). Any idea how I can solve the IE, and possibly the Opera compatibility problem? Thank you for your time.

• mscomctl.ocx on my dev machine gives me problems since security patch of MS

  - by Bronzato

  I am busy on this problem since 2 days ago and hope someone can get me out of it. I have Excel 2010 (full install 944Mb) on my Windows 8 computer. It works well. But when I modify my workbook (containing a ListView version 6.0) I am not able to run it on my client's computer. I get the error: Could Not Load An Object. Not Available on This Machine. Even it works well on my dev machine. The reason is: Microsoft applied a Security Patch (near august 2012 I think) on mscomctl.ocx and my Excel 2010 installation files (downloaded not long ago) contains the new version of mscomctl.ocx. The clients using my Excel file don't apply the security patch at this moment. Se everytime I publish my Excel file to client's computers (from my dev environment), I reference the new mscomctl.ocx. That's the problem. I already try to get the old mscomctl.ocx from client's computer and copy & register it on my dev machine but then I got errors (Class not registered, ...) when I create a userform and drag a listview on it. So: mscomctl.ocx on client's machine is version 6.1.98.13 from 2008. mscomctl.ocx on my dev machine is version 6.1.98.34 from 2012. My question: Does someone have an idea how to proceed to have a usable version of mscomctl.ocx on my dev machine? Thank you very much.

• Jquery passing an HTML element into a function

  - by christian

  I have an HTML form where I am going to copy values from a series of input fields to some spans/headings as the user populates the input fields. I am able to get this working using the following code: $('#source').keyup(function(){ if($("#source").val().length == 0){ $("#destinationTitle").text('Sample Title'); }else{ $("#destinationTitle").text($("#source").val()); } }); In the above scenario the html is something like: Sample Title Basically, as the users fills out the source box, the text of the is changed to the value of the source input. If nothing is input in, or the user deletes the values typed into the box some default text is placed in the instead. Pretty straightforward. However, since I need to make this work for many different fields, it makes sense to turn this into a generic function and then bind that function to each 's onkeyup() event. But I am having some trouble with this. My implementation: function doStuff(source,target,defaultValue) { if($(source).val().length == 0){ $(target).text(defaultValue); }else{ $(target).text($(source).val()); } } which is called as follows: $('#source').keyup(function() { doStuff(this, '"#destinationTitle"', 'SampleTitle'); }); What I can't figure out is how to pass the second parameter, the name of the destination html element into the function. I have no problem passing in the element I'm binding to via "this", but can't figure out the destination element syntax. Any help would be appreciated - many thanks!

• Committing to a different branch with commit -r

  - by Amarghosh

  Does CVS allow committing a file to a different branch than the one it was checked out from? The man page and some sites suggest that we can do a cvs ci -r branch-1 file.c but it gives the following error: cvs commit: Up-to-date check failed for `file.c' cvs [commit aborted]: correct above errors first! I did a cvs diff -r branch-1 file.c to make sure that contents of file.c in my BASE and branch-1 are indeed the same. I know that we can manually check out using cvs co -r branch-1, merge the main branch to it (and fix any merge issues) and then do a check in. The problem is that there are a number of branches and I would like to automate things using a script. This thread seems to suggest that -r has been removed. Can someone confirm that? If ci -r is not supported, I am thinking of doing something like: Make sure the branch versions and base version are the same with a cvs diff Check in to the current branch Keep a copy of the file in a temp file For each branch: Check out from branch with -r replace the file with the temp file Check in (it'll go the branch as -r is sticky) Delete the temp file The replacing part sounds like cheating to me - can you think of any potential issues that might occur? Anything I should be careful about? Is there any other way to automate this process?

• making an SQL date column visible to a Drupal view

  - by Donal

  I'm trying to make a table visible to Views. One of the columns has type date (as opposed to a Unix timestamp). The example I initially tried to copy from is in modules/comment.views.inc in the Views module: // timestamp (when comment was posted) $data['comments']['timestamp'] = array( 'title' => t('Post date'), 'help' => t('Date and time of when the comment was posted.'), 'field' => array( 'handler' => 'views_handler_field_date', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort_date', ), 'filter' => array( 'handler' => 'views_handler_filter_date', ), ); This makes the dates, which are all in the past year or so, show up as "1 Jan 1970 00:33", so evidently a value of '2010-05-12', for example, is being interpreted as 2010 seconds past 1 Jan 1970 00:00. Can anyone point me to a correct way of exporting date columns? EDIT: I'm following up on some clues found at http://drupal.org/node/476774 .

• Progressive enhancement of anchor tags to avoid onclick="return false;"

  - by Chris Beck

  Unobtrusive JS suggests that we don't have any onclick attributes in our HTML templates. <a href="/controller/foo/1">View Foo 1</a> A most basic progressive enhancement is to convert an that anchor tag to use XHR to retrieve a DOM fragment. So, I write JS to add an event listener for a."click" then make an XHR to a.href. Alas, the browser still wants to navigate to "/controller/foo". So, I write JS to dynamically inject a.onclick = "return false;". Still unobtrusive (I guess), but now I'm paying the the cost of an extra event handler. To avoid the cost of 2 event listeners, I could shove my function call into the onclick attribute <a href="/controller/foo/1" onclick="myXHRFcn(); return false;"> But that's grodo for all sorts of reasons. To make it more interesting, I might have 100 anchor tags that I want to enhance. A better pattern is a single listener on a parent node that relies on event bubbling. That's cool, but how do I short circuit the browser from navigating to the URL without this on every anchor node? onclick="return false;" Manipulating the href is not an option. It must stay intact so the context menu options to copy or open in new page work as expected.

• Visual Studio internal project references not always working

  - by Chris

  I am using Visual Studio and a solution with 10 or so projects in (mostly VB, some C#) which have various dependencies set up. Usually when I compile the solution it works fine. Occasionally when I do it I get a build error saying that one of the projects referenced is the wrong version (I think always the same one, possibly may be two that can cause problems). In this case going to the solution explorer and right clicking on the mentioned project and saying "rebuild" followed by another full build makes it work fine. I assume there is something set up wrong somewhere but I didn't set up the solution myself initially and a quick look through doesn't show anything immediately wrong. It feels like there is some kind of race condition, that VS is internally setting the version number of the project it needs before that project has been rebuilt and thus gets it wrong or something like that but I'm sure VS should handle all this sort of thing properly. Can anybody please suggest places that I could check for whether this has been correctly set up... And I should finally note that since I don't have reliable repro of this I may not be able to respond to questions too quickly. For example the obvious one of "Could you give the exact error message" will have to wait since I didn't think to copy it this morning, it was only after I cleared it up with the above steps that I thought to post here. Similarly any solutions may take a while to confirm.

• What's a good way to write batch scripts in C#?

  - by Scott Bilas

  I would like to write simple scripts in C#. Stuff I would normally use .bat or 4NT .btm files for. Copying files, parsing text, asking user input, and so on. Fairly simple but doing this stuff right in a batch file is really hard (no exceptions for example). I'm familiar with command line "scripting" wrappers like AxScript so that gets me part of the way there. What I'm missing is the easy file-manipulation framework. I want to be able to do cd(".."), copy(srcFile, destFile) type functionality. Tools I have tried: NANT, which we use in our build process. Not a good scripting tool. Insanely verbose XML syntax and to add a simple function you must write an extension assembly. Can't do it inline. PowerShell. Looks great, but I just haven't been able to switch over to this as my primary shell. Too many differences from 4NT. Whatever I do needs to run from an ordinary command prompt and not require a special shell to run it through. Can PowerShell be used as a script executor? Perl/Python/Ruby. Really hate learning an entirely new language and framework just to do batch file operations. Haven't been able to dedicate the time I need to do this. Plus, we're a 99% .NET shop for our toolchain and I really want to leverage our existing experience and codebase. Are there frameworks out there that are trying to solve this problem of "make a batch file in C#" that you have used? I want the power of C#/.NET with the immediate-mode type functionality of a typical cmd.exe shell language. Am I alone in wanting something like this?

• Attempted GCF app for Android

  I am new to Android and am trying to create a very basic app that calculates and displays the GCF of two numbers entered by the user. Here is a copy of my GCF.java: package com.example.GCF; import java.util.Arrays; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; public class GCF extends Activity { private TextView mAnswer; private EditText mA, mB; private Button ok; private String A, B; private int iA, iB; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mA = (EditText) findViewById(R.id.entry); mB = (EditText) findViewById(R.id.entry1); ok = (Button) findViewById(R.id.ok); mAnswer = (TextView) findViewById(R.id.answer1); ok.setOnClickListener(new OnClickListener() { public void onClick(View v) { A = mA.getText().toString(); B = mB.getText().toString(); } }); // the String to int conversion happens here iA = Integer.parseInt(A.trim()); iB = Integer.parseInt(B.trim()); while (iA != iB) { int[] nums={ iA, iB, Math.abs(iA-iB) }; Arrays.sort(nums); iA=nums[0]; iB=nums[1]; } updateDisplay(); } private void updateDisplay() { mAnswer.setText( new StringBuilder().append(iA)); } } Any Suggestions?

• How can I create an Assembly program WITHOUT using libraries?

  - by Newbie

  Hello. I've literally only just started looking to learn Assembly language. I'm using the NASM assembler on Windows Vista. Usually, when I begin to learn a new language, I'll copy someone else's Hello World code and try to understand it line-by-line. However, I'm finding it suprisingy difficult to find a Hello World program that doesn't reference other libraries! You see, there's no point trying to understand each line of the code if it is closely linked with a whole library of additional code! One of the reasons I want to learn Assembly is so that I can have near complete control over the programs I write. I don't want to be depending on any libraries. And so my question is this: Can anyone give me NASM-compatible Assembly code to a completely stand-alone Hello World program that can output to the Windows Vista console? Alternatively, I appreciate that a library may be required to tell the pogram WHERE to print the output (ie. the Windows console). Other than that, I can't see why any libraries should be required. Am I overlooking anything?

• IList<T> vs IEnumerable<T>. What is more efficient IList<T> or IEnumerable<T>

  - by bigb

  What is more efficient way to make methods return IList<T> or IEnumerable<T>? IEnumerable<T> it is immutable collection but IList<T> mutable and contain a lot of useful methods and properties. To cast IList<T> to IEnumerable<T> it is just reference copy: IList<T> l = new List<T>(); IEnumerable<T> e = l; To cast IEnumerable<T> to List<T> we need to iterate each element or to call ToList() method: IEnumerable<T>.ToList(); or may pass IEnumerable<T> to List<T> constructor which doing the same iteration somewhere within its constructor. List<T> l = new List<T>(e); Which cases you think is more efficient? Which you prefer more in your practice?

• Replacing/Adding resources (icon) programmatically in c#?

  - by reverendo

  I am trying to replace (or add in the case it doesn't exists) icons from .exe files using c#. So far I got this: string filename = "c:\\test.exe"; IntPtr hResource = BeginUpdateResource(filename, true); if (hResource.ToInt32() == 0) throw new Exception("File Not Found"); byte[] ico = System.IO.File.ReadAllBytes("C:\\icon.ico"); IntPtr unmanagedPointer = Marshal.AllocHGlobal(ico.Length); Marshal.Copy(ico, 0, unmanagedPointer, ico.Length); if (UpdateResource(hResource, "Icon", "1", 1033, unmanagedPointer, Convert.ToUInt32(ico.Length)) != false) { MessageBox.Show("Updated"); EndUpdateResource(hResource, false); } Marshal.FreeHGlobal(unmanagedPointer); "Icon", "1", 1033 <- I got this data by opening test.exe with Resource Hacker. I do get the messagebox "Updated", and if I open the resulting exe in Resource Hacker the resource gets replaced but the icon doesn't appear, its just empty. Also that code wont replace, the type "Icon" in the resource, it will delete everything and add that "Icon" and if I use BeginUpdateResource(path, false); it will not replace it neither but it will add ANOTHER "Icon". Where can I find an example to replace/add the icon using c# disregarding the name the resource use for the icon or if the resource doesn't exist?

• Counting a cell up per Objects

  - by Auro

  hey i got a problem once again :D a little info first: im trying to copy data from one table to an other table(structure is the same). now one cell needs to be incremented, beginns per group at 1 (just like a histroy). i have this table: create table My_Test/My_Test2 ( my_Id Number(8,0), my_Num Number(6,0), my_Data Varchar2(100)); (my_Id, my_Num is a nested PK) if i want to insert a new row, i need to check if the value in my_id already exists. if this is true then i need to use the next my_Num for this Id. i have this in my Table: My_Id My_Num My_Data 1 1 'test1' 1 2 'test2' 2 1 'test3' if i add now a row for my_Id 1, the row would look like this: i have this in my Table: My_Id My_Num My_Data 1 3 'test4' this sounds pretty easy ,now i need to make it in a SQL and on SQL Server i had the same problem and i used this: Insert Into My_Test (My_Id,My_Num,My_Data) SELECT my_Id, ( SELECT CASE ( CASE MAX(a.my_Num) WHEN NULL THEN 0 Else Max(A.My_Num) END) + b.My_Num WHEN NULL THEN 1 ELSE ( CASE MAX(a.My_Num) WHEN NULL THEN 0 Else Max(A.My_Num) END) + b.My_Num END From My_Test A where my_id = 1 ) ,My_Data From My_Test2 B where my_id = 1; this Select gives null back if no Rows are found in the subselect is there a way so i could use max in the case? and if it give null back it should use 0 or 1? greets Auro

• mysql query not running correctly from inside the application

  - by Mala

  I am completely stumped. Here is my php (CodeIgniter) code: function mod() { $uid = $this->session->userdata('uid'); $pid = $this->input->post('pid'); if ($this->_verify($uid,$pid)) { $name = $this->input->post('name'); $price = $this->input->post('price'); $curr = $this->input->post('curr'); $url = $this->input->post('url'); $query = $this->db->query("UPDATE items SET name=".$this->db->escape($name).", price=".$this->db->escape($price).", currency=".$this->db->escape($curr),", url=".$this->db->escape($url)." WHERE pid=".$this->db->escape($pid)." LIMIT 1"); } header('location: '.$this->session->userdata('current')); } The purpose of this code is to modify the properties (name, price, currency, url) of a row in the 'items' table (priary key is pid). However, for some reason, allowing this function to run once modifies the name, price, currency and url of ALL entries in the table, regardless of their pid and of the LIMIT 1 thing I tacked on the end of the query. It's as if the last line of the query is being completely ignored. As if this wasn't strance enough, I replaced "$query = $this->db->query(" with an "echo" to see the SQL query being run, and it outputs a query much like I would expect: UPDATE items SET name='newname', price='newprice', currency='newcurrency', url='newurl' WHERE pid='10' LIMIT 1 Copy-pasting this into a MySQL window acts exactly as I want: it modifies the row with the selected pid. What is going on here???

• Is it theoretically possible to emulate a human brain on a computer?

  - by JoelK

  Our brain consists of billions of neurons which basically work with all the incoming data from our senses, handle our consciousness, emotions and creativity as well as our hormone system, etc. So I'm completely new to this topic but doesn't each neuron have a fixed function? E.g.: If a signal of strength x enters, if the last signal was x ms ago, redirect it. From what I've learned in biology about our nerves system which includes our brain because both consist of simple neurons, it seems to me as our brain is one big, complicated computer. Maybe so complicated that things such as intelligence and cognition become possible? As the most complicated things about a neuron pretty much are the chemical aspects on generating an electric singal, keeping itself alive, and eventually segmenting itself, it should be pretty easy emulating some on a computer, or? You won't have to worry about keeping your virtual neuron alive, or? If you can emulate a single neuron on a computer, which shouldn't be too hard, could you theoretically emulate more than 1000 billions of them, recreating intelligence, cognition and maybe even creativity? In my question I'm leaving out the following aspects: Speed of our current (super) computers Actually writing a program for emulating neurons I don't know much about this topic, please tell me if I got anything wrong :) (My secret goal: Make a copy of my brain and store it on some 10 million TB HDD and make someone start it up in the future)

  I have the following vertex declration: struct MESHVERTInstanced { float x, y, z; // Position float nx, ny, nz; // Normal float tu, tv; // Texcoord float idx; // index of the vertex! float tanx, tany, tanz; // The tangent const static D3DVERTEXELEMENT9 Decl[6]; static IDirect3DVertexDeclaration9* meshvertinstdecl; }; And I declare it as such: const D3DVERTEXELEMENT9 MESHVERTInstanced::Decl[] = { { 0, 0, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_POSITION, 0 }, { 0, 12, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_NORMAL, 0 }, { 0, 24, D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 0 }, { 0, 32, D3DDECLTYPE_FLOAT1, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 1 }, { 0, 36, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TANGENT, 0 }, D3DDECL_END() }; What I try to do next is copy an ID3DXMesh into another one with the new vertex declaration as such: model->CloneMesh( model->GetOptions(), MESHVERTInstanced::Decl, gd3dDevice, &pTempMesh ); When I try to get the FVF size of pTempMesh (D3DXGetFVFVertexSize(pTempMesh-GetFVF())) I get '0' though the size should be 48. The whole thing is fine if I don't have the last declaration, '{ 0, 36, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TANGENT, 0 },' in it and the CloneMesh function does not return a FAIL. I've also tried using different declarations such as D3DDECLUSAGE_TEXCOORD and that has worked fine, returning a size of 48. Is there something specific about D3DDECLUSAGE_TANGENT I don't know? I'm at a complete loss as to why this isn't working...

• Freeing of allocated memory in Solaris/Linux

  - by user355159

  Hi, I have written a small program and compiled it under Solaris/Linux platform to measure the performance of applying this code to my application. The program is written in such a way, initially using sbrk(0) system call, i have taken base address of the heap region. After that i have allocated an 1.5GB of memory using malloc system call, Then i used memcpy system call to copy 1.5GB of content to the allocated memory area. Then, I freed the allocated memory. After freeing, i used again sbrk(0) system call to view the heap size. This is where i little confused. In solaris, eventhough, i freed the memory allocated (of nearly 1.5GB) the heap size of the process is huge. But i run the same application in linux, after freeing, i found that the heap size of the process is equal to the size of the heap memory before allocation of 1.5GB. I know Solaris does not frees memory immediately, but i don't know how to tune the solaris kernel to immediately free the memory after free() system call. Also, please explain why the same problem does not comes under Linux? Can anyone help me out of this? Thanks, Santhosh.

• MSI File/Registry failures on Windows Server 2008/Windows 7 (x64)

  - by Luca

  I'm trying to deploy an application on Windows Server 2008 (SP2 x64) and Windows 7 (x64), using VS2005 Installer Project. The MSI version (I think) it the 2.0. Everything works fine, except that some registry keys and some files are not copied on the install machine. The MSI system doesn't notify about nothing (and I don't know whether MSI logs its operations). Are there incompatibilities between my MSI installer project and these new OSes? It seems to me that the OS protect itself for being modified in some part. For example, I'm trying to set the registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\WinLogon\SpecialAccounts\UserList\User but it is not created. In the same installer there are many other keys, which are created like expected (as they always did before on Windows XP and Windows Server 2003). To provide another example, I'm trying to install the file %SystemFolder%\oobe\info\backgrounds\backgroundDefault.jpg (where %SystemFolder% is typically "C:\Windows\System32"), but the file is not copied at all!!! What's going on? I've found the backgroundDefault.jpg file is located in another directory: %SystemRoot%\SysWOW64\oobe\info. But I've not specified nothing about a System (64 bit) folder. How can I copy the file in the right place?
