• Using CMake with Eclipse CDT, quickly switch targets?

  - by Cheezmeister

  I'm using the CDT4 - MinGW Makefiles generator. Project-Build All successfully builds the target (a shared library) but it seems I would have to (A) open a project settings page and type in the target, hoping it's spelled right*, or (B) run make from a terminal to "build" the install and package targets. I noticed a promising Project-Make Target entry, but the Create... and Build... sub-entries are greyed-out. Any hints would be appreciated! *http://publib.boulder.ibm.com/infocenter/rsdhelp/v7r0m0/topic/org.eclipse.cdt.doc.user/concepts/cdt_c_build_over.htm

  - by Michael Lai

  I am new to J2ee. I have experience in Java core, JSP,Servlet, XML, HTML, What should i learn to step into the world of J2EE? Framework(Spring, Hibernate, Struts)? But the framework is too abstract for me.I saw lots of job post which requires frameworks, some jobs require EJB,JPA. I do not where to start. Any experts can give me hints on that? I found the tutorial of J2EE 5 published by ORACLE is not easy to understand. Too much jargon....

• How to deal with a coworker who keeps asking instead of searching herself?

  - by mafutrct

  I'm lucky enough to share a room with 3 other people at work. One of them, a senior programmer who's very talkative in general, tends to ask me various questions throughout the day. While some of them are surely ' legitimate', many questions could have been answered by putting in just slightly more search effort on their part. I really don't mind be asked stuff, and I can also cope with beginner questions, but this is seriously interrupting my flow. I clearly remember Joel talking about how private offices increase productivity because they prevent too easy questions from being asked. How should I deal with this situation? Getting a private office is out of the question, sadly. It's difficult to approach him directly, and he blissfully ignored the slight hints I tried to give.

• Are where any Visual Studio addings for true 'smart tabs'?

  - by Eye of Hell

  Hello. 'Smart Tabs' concept allows to automatically insert tab character for block indentation and space characters for in-block formatting. It's described here. Unfortunately, Visual Studio's 'smart tabs' option in text editor settings just indents text on enter press. Same name, completely different and near useless thing :). So, maybe someone knows of a visual studio addin that can change how 'tab' key work so it will insert tab characters and space characters according to rules mentioned above? Any hints are welcome.

• [cli/linux] get plain text from raw emails (not attachments extraction)

  - by etuardu

  Hi, having a raw email as input (i.e. the text between "DATA" and "." sent by a smtp client) I need to extract the mail content (which I know is always text only) as plain text. This means decoding transfer encoding (if any: could be base64 or quoted-printable), merging mutiparts (if any), and stripping headers. I tried various tools that would do that: mewdecode, uudecode, uudeview... I only managed to get this last one to work, but it won't output anything if the mail is not MIME encoded and it stores its output in an unpredictable (nor forceable) filename, so it's hard to use it in a not-interactive shell script. Since this is a pretty common job (every mail client have to do that), it's weird it's so complicated. Do you have some hints? (Actually, forcing uudeview to output in a certain file would be good enough). Thank you!

• Using a framework in a PreferencePane

  - by Jonathan

  Hi, i am currently trying to implement a "third party framework" (FeedbackReporter.Framework) into my preferencepane. Unfortunately I am getting the following error all the time when trying to launch my preference pane: 16.05.10 23:13:30 System Preferences[32645] dlopen_preflight failed with dlopen_preflight(/Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane): Library not loaded: @executable_path/../Frameworks/FeedbackReporter.framework/Versions/A/FeedbackReporter Referenced from: /Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane Reason: image not found for /Users/me/Library/PreferencePanes/myPane.prefPane As far as I read so far, this problem is probably caused because my prefPane is no actual app, but a "plugin" of "System Settings.app" and thus @executable_path resolves to a path within the bundle of this app, instead of the bundle of my prefpane. But I don't really picked up howto fix this problem. I guess it must be fairly easy since it should be a usual case that people use non-apple-frameworks in PreferencePanes. Thanks for your hints!

• Voices disappear when using headphones. [closed]

  - by James

  How do I declare a variable in C? P.S. I have a pair of SteelSeries Siberia headphones. I've noticed that when watching some films the voices are completely silent, yet when I unplug the headset and listen through my speakers they are there and sound normal. I have no other software that could be interfering with it and it happens regardless of the software I use for playback (I've tried VLC, WMP and Quicktime). It is so strange, and it almost sounds deliberate - the rest of the audio is untouched but voices disappear. The films only have single audio tracks, and it doesn't happen with every film. Can anyone give me any hints as to what could possibly cause this? I am stumped!

• Why does this JavaScript destroys my layout in Internet Explorer?

  - by Sebi

  I'm using a small CMS for a small site (http://www.ovlu.li/cms/). There I include a JavaScript on the first site to open an image in a popup: <script type="text/javascript"> function pop(file) { helpwindow = window.open(file, "Vaterland", "width=600, height=796", "directories=no", "toolbar=no", "location=no", "status=no", "menubar=no", "resizable=no"); helpwindow.focus(); return false; } </script> This works fine in FireFox, Chrome and Safari, but unfortunately, in Internet Explorer this script totally destroys the layout of the site where it is contained. Nevertheless it works. And all other sites are also working correctly. Any hints?

• How can I figure out where all these extra sqlite3 selects are being generated in my rails app?

  - by radixhound

  I'm trying to figure out where a whole pile of extra queries are being generated by my rails app. I need some ideas on how to tackle it. Or, if someone can give me some hints, I'd be grateful. I get these: SQL (1.0ms) SELECT name FROM sqlite_master WHERE type = 'table' AND NOT name = 'sqlite_sequence' SQL (0.8ms) SELECT name FROM sqlite_master WHERE type = 'table' AND NOT name = 'sqlite_sequence' SQL (0.8ms) SELECT name FROM sqlite_master WHERE type = 'table' AND NOT name = 'sqlite_sequence' repeated over and over on every request to the DB (as much as 70 times for a single request) I tried installing a plugin that traced the source of the queries, but it really didn't help at all. I'm using the hobofields gem, dunno if that is what's doing it but I'm somewhat wedded to it at the moment Any tips on hunting down the source of these extra queries?

• Apache crashes after installing mysqli

  - by Marco P.

  System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

• Shell Sort problem

  - by user191603

  Show the result of running Shell Sort on the input 9,8,7,6,5,4,3,2,1 using increments { 1,3,7 }. I have done this part. the result is: 9 8 7 6 5 4 3 2 1 (original) 2 1 7 6 5 4 3 9 8 ( 7-sort ) 2 1 4 3 5 7 6 9 8 ( 3-sort ) 1 2 3 4 5 6 7 8 9 ( 1-sort ) Then the question requires me to determine the running time of Shell Sort using Shell's increments of N/2, N/4, ..., 1 for sorted input. I am not quite sure how to answer the second question as I don't understand the requirement of this question. So, would anyone give some hints to let me finish this question? Thank you for your help first!

• Calling R Script from within C-Code

  - by tiny81

  Hi, Is there a way to call an R-Script within C-Code? I did find the R Api for C (chaper 6. of the 'Writing R Extensions' manual), but as far as I understood this does "only" allow to call the C-Implementation of R. Of cause I could call the R-Script via shell, but that's no solution for me, since this does not allow proper passing of data (at least no if I don't what to write the data into a Csv-File or something like this). Is there a easy way of using the R to C parser beforehand? Any hints you can give me? regards, Tiny

• Get the folder where the last mailitem was moved in Outlook?

  - by user2892971

  I have a vbscript macro that I'm using in Outlook. It moves a mailitem to some folder, say X. After I run the macro and I try to manually move a mailitem from Outlook with Control-v, it defaults to folder X. I would like Control-v to default to the folder that it would have used before I ran the macro. Is there some way in VBScript to find out what folder the last mailitem was move to, and to return that to be the default folder after I run my script? Or is there a way to move a mailitem in my script without the destination folder being remembered by Outlook Control-v after I run the script? Thanks for any hints.

• [VC++ 2010] Stack around the variable 'xyz' was corrupted.

  - by tirolerhut

  hi, I'm trying to get some simple piece of code I found on a website to work in VC++ 2010 on windows vista 64: #include "stdafx.h" #include <windows.h> int _tmain(int argc, _TCHAR* argv[]) { DWORD dResult; BOOL result; char oldWallPaper[MAX_PATH]; result = SystemParametersInfo(SPI_GETDESKWALLPAPER, sizeof(oldWallPaper)-1, oldWallPaper, 0); fprintf(stderr, "Current desktop background is %s\n", oldWallPaper); return 0; } it does compile, but when I run it, I always get this error: Run-Time Check Failure #2 - Stack around the variable 'oldWallPaper' was corrupted. I'm not sure what is going wrong, but I noticed, that the value of oldWallPaper looks something like "C\0\:\0\0U\0s\0e\0r\0s[...]" -- I'm wondering where all the \0s come from. A friend of mine compiled it on windows xp 32 (also VC++ 2010) and is able to run it without problems any clues/hints/opinions? thanks

• Implemention of scattering in this paper

  - by pelb

  Hi, For some time I tried implementing the scattering model described in this paper: Salama Paper The BRDF part of this paper is pretty clear and straightforward. Where I am hanging is the scattering part. When scattering at the first hitpoint once only, I'm just not getting the same results as proposed by the images in the very same paper. Of course I'm scattering multiply rays inside the proposed scattering cone and averaging the results of the different rays. Does anyone have more or less concrete ideas on the implementation of this nice and beautiful illustrative rendering method. I am glad and thankful for any hints.

• NSMutableArray with NSDictionary to Labels without the surrounding brackets

  - by bigubosu

  I'm making a scoreboard for my game. And when I do a NSLog of the data it comes out as this: { name = TTY; score = "3.366347"; } So my question is how do I remove this brackets and also just grab the name (TTY) and score (3.36 without the quotations) and place them in variable for me to put into labels. Currently I can place them in labels but they have the lingering curly braces "{" and "}". Any hints would be helpful as I'm happy to search further I just don't know the vocab to search for it. thanks

• Android strange behavior with listview and custom cursor adapter

  - by Michael Little

  I have a problem with a list view and a custom cursor adapter and I just can't seem to figure out what is wrong with my code. Basically, in my activity I call initalize() that does a bunch of stuff to handle getting the proper data and initializing the listview. On first run of the activity you can see from the images that one of the items is missing from the list. If I go to another activity and go back to this activity the item that was missing shows up. I believe it has something to do with setContentView(R.layout.parent). If I move that to my initialize() then the item never shows up even when returning from another activity. So, for some reason, returning from another activity bypasses setContentView(R.layout.parent) and everything works fine. I know it's impossible for me to bypass setContentView(R.layout.parent) so I need to figure out what the problem is. Also, I did not include the layout because it is nothing more then two textviews. Also, the images I have attached do not show that the missing item is the last one on the list. Custom Cursor Adapter: public class CustomCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public CustomCursorAdapter (Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout; } public View newView(Context context, Cursor cursor, ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(context); final View view = inflater.inflate(layout, parent, false); return view; } @Override public void bindView(View v, Context context, Cursor c) { if (c.getColumnName(0).matches("section")){ int nameCol = c.getColumnIndex("section"); String section = c.getString(nameCol); TextView section_text = (TextView) v.findViewById(R.id.text1); if ((section.length() > 0)) { section_text.setText(section); } else { //so we don't have an empty spot section_text.setText(""); section_text.setVisibility(2); section_text.setHeight(1); } } else if (c.getColumnName(0).matches("code")) { int nameCol = c.getColumnIndex("code"); String mCode = c.getString(nameCol); TextView code_text = (TextView) v.findViewById(R.id.text1); if (code_text != null) { int i = 167; byte[] data = {(byte) i}; String strSymbol = EncodingUtils.getString(data, "windows-1252"); mCode = strSymbol + " " + mCode; code_text.setText(mCode); code_text.setSingleLine(); } } if (c.getColumnName(1).matches("title")){ int nameCol = c.getColumnIndex("title"); String mTitle = c.getString(nameCol); TextView title_text = (TextView) v.findViewById(R.id.text2); if (title_text != null) { title_text.setText(mTitle);

• Some problems with GridView in webpart with multiple filters.

  - by NF_81

  Hello, I'm currently working on a highly configurable Database Viewer webpart for WSS 3.0 which we are going to need for several customized sharepoint sites. Sorry in advance for the large wall of text, but i fear it's necessary to recap the whole issue. As background information and to describe my problem as good as possible, I'll start by telling you what the webpart shall do: Basically the webpart contains an UpdatePanel, which contains a GridView and an SqlDataSource. The select-query the Datasource uses can be set via webbrowseable properties or received from a consumer method from another webpart. Now i wanted to add a filtering feature to the webpart, so i want a dropdownlist in the headerrow for each column that should be filterable. As the select-query is completely dynamic and i don't know at design time which columns shall be filterable, i decided to add a webbrowseable property to contain an xml-formed string with filter information. So i added the following into OnRowCreated of the gridview: void gridView_RowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.Header) { for (int i = 0; i < e.Row.Cells.Count; i++) { if (e.Row.Cells[i].GetType() == typeof(DataControlFieldHeaderCell)) { string headerText = ((DataControlFieldHeaderCell)e.Row.Cells[i]).ContainingField.HeaderText; // add sorting functionality if (_allowSorting && !String.IsNullOrEmpty(headerText)) { Label l = new Label(); l.Text = headerText; l.ForeColor = Color.Blue; l.Font.Bold = true; l.ID = "Header" + i; l.Attributes["title"] = "Sort by " + headerText; l.Attributes["onmouseover"] = "this.style.cursor = 'pointer'; this.style.color = 'red'"; l.Attributes["onmouseout"] = "this.style.color = 'blue'"; l.Attributes["onclick"] = "__doPostBack('" + panel.UniqueID + "','SortBy$" + headerText + "');"; e.Row.Cells[i].Controls.Add(l); } // check if this column shall be filterable if (!String.IsNullOrEmpty(filterXmlData)) { XmlNode columnNode = GetColumnNode(headerText); if (columnNode != null) { string dataValueField = columnNode.Attributes["DataValueField"] == null ? "" : columnNode.Attributes["DataValueField"].Value; string filterQuery = columnNode.Attributes["FilterQuery"] == null ? "" : columnNode.Attributes["FilterQuery"].Value; if (!String.IsNullOrEmpty(dataValueField) && !String.IsNullOrEmpty(filterQuery)) { SqlDataSource ds = new SqlDataSource(_conStr, filterQuery); DropDownList cbx = new DropDownList(); cbx.ID = "FilterCbx" + i; cbx.Attributes["onchange"] = "__doPostBack('" + panel.UniqueID + "','SelectionChange$" + headerText + "$' + this.options[this.selectedIndex].value);"; cbx.Width = 150; cbx.DataValueField = dataValueField; cbx.DataSource = ds; cbx.DataBound += new EventHandler(cbx_DataBound); cbx.PreRender += new EventHandler(cbx_PreRender); cbx.DataBind(); e.Row.Cells[i].Controls.Add(cbx); } } } } } } } GetColumnNode() checks in the filter property, if there is a node for the current column, which contains information about the Field the DropDownList should bind to, and the query for filling in the items. In cbx_PreRender() i check ViewState and select an item in case of a postback. In cbx_DataBound() i just add tooltips to the list items as the dropdownlist has a fixed width. Previously, I used AutoPostback and SelectedIndexChanged of the DDL to filter the grid, but to my disappointment it was not always fired. Now i check __EVENTTARGET and __EVENTARGUMENT in OnLoad and call a function when the postback event was due to a selection change in a DDL: private void FilterSelectionChanged(string columnName, string selectedValue) { columnName = "[" + columnName + "]"; if (selectedValue.IndexOf("--") < 0 ) // "-- All --" selected { if (filter.ContainsKey(columnName)) filter[columnName] = "='" + selectedValue + "'"; else filter.Add(columnName, "='" + selectedValue + "'"); } else { filter.Remove(columnName); } gridView.PageIndex = 0; } "filter" is a HashTable which is stored in ViewState for persisting the filters (got this sample somewhere on the web, don't remember where). In OnPreRender of the webpart, i call a function which reads the ViewState and apply the filterExpression to the datasource if there is one. I assume i had to place it here, because if there is another postback (e.g. for sorting) the filters are not applied any more. private void ApplyGridFilter() { string args = " "; int i = 0; foreach (object key in filter.Keys) { if (i == 0) args = key.ToString() + filter[key].ToString(); else args += " AND " + key.ToString() + filter[key].ToString(); i++; } dataSource.FilterExpression = args; ViewState.Add("FilterArgs", filter); } protected override void OnPreRender(EventArgs e) { EnsureChildControls(); if (WebPartManager.DisplayMode.Name == "Edit") { errMsg = "Webpart in Edit mode..."; return; } if (useWebPartConnection == true) // get select-query from consumer webpart { if (provider != null) { dataSource.SelectCommand = provider.strQuery; } } try { int currentPageIndex = gridView.PageIndex; if (!String.IsNullOrEmpty(m_SortExpression)) { gridView.Sort("[" + m_SortExpression + "]", m_SortDirection); } gridView.PageIndex = currentPageIndex; // for some reason, the current pageindex resets after sorting ApplyGridFilter(); gridView.DataBind(); } catch (Exception ex) { Functions.ShowJavaScriptAlert(Page, ex.Message); } base.OnPreRender(e); } So i set the filterExpression and the call DataBind(). I don't know if this is ok on this late stage.. don't have a lot of asp.net experience after all. If anyone can suggest a better solution, please give me a hint. This all works great so far, except when i have two or more filters and set them to a combination that returns zero records. Bam ... gridview gone, completely - without a possiblity of changing the filters back. So i googled and found out that i have to subclass gridview in order to always show the headerrow. I found this solution and implemented it with some modifications. The headerrow get's displayed and i can change the filters even if the returned result contains no rows. But finally to my current problem: When i have two or more filters set which return zero rows, and i change back one filter to something that should return rows, the gridview remains empty (although the pager is rendered). I have to completly refresh the page to reset the filters. When debugging, i can see in the overridden CreateChildControls of the grid, that the base method indeed returns 0, but anyway... the gridView.RowCount remains 0 after databinding. Anyone have an idea what's going wrong here?

• NOOB Memory Problem - EXC_BAD_ACCESS (OBJ-C/iPhone)

  - by Michael Bordelon

  I have been banging my head against the wall for a couple days and need some help. I have a feeling that I am doing something really silly here, but I cannot find the issue. This is the controller for a table view. I put the SQL in line to simplify it as part of the troubleshooting of this error. Normally, it would be in an accessor method in a model class. It gets through the SQL read just fine. Finds the two objects, loads them into the todaysWorkout array and then builds the cells for the table view. The table view actually comes up on the scree and then it throws the EXC_BAD_ACCESS.

• Edit Contact code worked in 1.6 but doesn't work on Droid 2.1?

  - by user225405

  Hi All, I had some fairly simple code in my app to invoke Edit Contact activity on a known good contact index that worked in Android 1.6 but is broken for me now in Android 2.1 on the Droid. I built a sample activity/app 'EdCon' to show this: package com.jbh; import android.app.Activity; import android.content.Intent; import android.net.Uri; import android.os.Bundle; public class EdCon extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Build an intent to edit a known good contact index Intent i; i = new Intent(Intent.ACTION_EDIT); i.setData(Uri.parse("content://contacts/people/10")); startActivity(i); } } When I run this on my G1 running 1.6 it works as expected i.e. brings up the Edit Contact screen for the known index and then I can hit BACK to return to "Hello World, EdCon". When I run this on the Droid under 2.1 I get the following: 05-07 15:35:57.787: INFO/ActivityManager(1013): Starting activity: Intent { act=android.intent.action.MAIN
