  • Switch to tab by typing a substring of its name in Visual Studio 2005

    - by Vineus
    Is there a way to navigate between tabs in VS similar to the emacs iswtichb-mode or Firefox ubiquity switch tab mode (https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1_Author_Tutorial#Switching_Tabs) ? In these apps, you just type a substring of the title of the tab (or buffer for emacs) to switch to this tab. For instance, to switch to a tab named "App_Code/Data/MyProgram.cs", you just invoke the tab switching command and then type "Progr" for instance to list all the tab whose name matches this string, including "MyProgram.cs". It's much easier to switch between tabs this way when you have a lot of documents open and when you now where to go (which is the case in most situation) Thank you !

  • C#: How to set AsyncWaitHandle in Compact Framework?

    - by Thorsten Dittmar
    Hi, I'm using a TcpClient in one of my Compact Framework 2.0 applications. I want to receive some information from a TCP server. As the Compact Framework does not support the timeout mechanisms of the "large" framework, I'm trying to implement my own timeout-thing. Basically, I want to do the following: IAsyncResult result = client.BeginRead(buffer, 0, size, ..., stream); if (!result.AsyncWaitHandle.WaitOne(5000, false)) // Handle timeout private void ReceiveFinished(IAsyncResult ar) { NetworkStream stream = (NetworkStream)ar.AsyncState; int numBytes = stream.EndRead(ar); // SIGNAL IASYNCRESULT.ASYNCWAITHANDLE HERE ... HOW?? } I'd like to call Set for the IAsyncResult.AsyncWaitHandle, but it doesn't have such a method and I don't know which implementation to cast it to. How do I set the wait handle? Or is it automatically set by calling EndRead? The documentation suggests that I'd have to call Set myself... Thanks for any help!

  • Can you access registers from python functions in vim

    - by Michael Anderson
    It seems vims python sripting is designed to edit buffer and files rather than work nicely with vims registers. You can use some of the vim packages commands to get access to the registers but its not pretty. My solution for creating a vim function using python that uses a register is something like this. function printUnnamedRegister() python >> EOF print vim.eval('@@') EOF Setting registers may also be possible using something like function setUnnamedRegsiter() python >> EOF s = "Some \"crazy\" string\nwith interesting characters" vim.command('let @@="%s"' % myescapefn(s) ) EOF However this feels a bit cumbersome and I'm not sure exactly what myescapefn should be. So I've never been able to get the setting version to work properly. So if there's a way to do something more like function printUnnamedRegister() python >> EOF print vim.getRegister('@') EOF function setUnnamedRegsiter() python >> EOF s = "Some \"crazy\" string\nwith interesting characters" vim.setRegister('@',s) EOF Or even a nice version of myescapefn I could use then that would be very handy.

  • Rendering formatted text in a direct3d application

    - by Fire Lancer
    I need to render some formatted text (colours, different font sizes, underlines, bold, etc) however I'm not sure how to go about doing it. D3DXFont only allows text of a single font/size/weight/colour/etc to be rendered at once, and I cant see a practical way to "combine" multiple calls to ID3DXFont::DrawText to do such things... I looked around and there doesn't seem to be any existing libraries that do these things, but I have no idea how to implement such a text renderer, and I couldn't even find any documentation on how such a text render would work, only rendering simple fixed width, ASCII bitmap fonts which looking at it is probably an entirely different approach that is only suitable for rendering simple blocks of text where Unicode is not important. If there's no direct3d font renders capable of doing this, is there any other renderers (eg for use in rendering rich text in a normal window), and would rendering those to a texture in RAM, then uploading that to the video card to render onto the back buffer yield reasonable performance?

  • Passing parameters between interrupt handlers on a Cortex-M3 ...

    - by Captain NedD
    I'm building a light kernel for a Cortex-M3. From a high priority interrupt I'd like to invoke some code to run in a lower priority interrupt and pass some parameters along. I don't want to use a queue to post work to the lower priority interrupt. I just have a buffer and size to pass to it. In the proramming manual it says that the SVC interrupt handler is synchronous which presumably means that if you invoke it from an interrupt that's a lower priority than SVC's handler it gets called immediately (the upshot of this being that you can pass parameters to it as though it were a function call (a little like the BIOS calls in MS-DOS)). I'd like to do it the other way: passing parameters from a high priority interrupt to a lower priority one (at the moment I'm doing it by leaving the parameters in a fixed location in memory). What's the best way to do this (if at all possible)? Thanks,

  • glTexImage2D behavior on iPhone and other OpenGL ES platforms

    - by spurserh
    Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. I suspect that the use of glTexImage2D with one or two frames of look-ahead, that is, using several textures so that the glTexImage2D call can be initiated a frame or two ahead, will allow for sufficient parallelism to play in real time if the system is capable of it at all. Is my assumption true that the driver will handle the actual data transfer to the hardware asynchronously after glTexImage2D returns, assuming I don't try to use the texture or call glFinish/glFlush? Is there a better way to do this with OpenGL ES? Thank you very much, Sean

  • Integrate Cppcheck with Emacs

    - by N.N.
    Is it possible to integrate Cppcheck with Emacs in a more sophisticated way than simply calling the shell command on the current buffer? I would like Emacs to be able to parse Cppcheck's messages and treat them as messages from a compiler (similar to how compile works), such as using C-x ` to visit the targets of Cppcheck's messages. Here is some example output Cppcheck: $ cppcheck --enable=all test.cpp Checking test.cpp...

  • help in the Donalds B. Johnson's algorithm, i cannot understand the pseudo code (PART II)

    - by Pitelk
    Hi all , i cannot understand a certain part of the paper published by Donald Johnson about finding cycles (Circuits) in a graph. More specific i cannot understand what is the matrix Ak which is mentioned in the following line of the pseudo code : Ak:=adjacency structure of strong component K with least vertex in subgraph of G induced by {s,s+1,....n}; to make things worse some lines after is mentins " for i in Vk do " without declaring what the Vk is... As far i have understand we have the following: 1) in general, a strong component is a sub-graph of a graph, in which for every node of this sub-graph there is a path to any node of the sub-graph (in other words you can access any node of the sub-graph from any other node of the sub-graph) 2) a sub-graph induced by a list of nodes is a graph containing all these nodes plus all the edges connecting these nodes. in paper the mathematical definition is " F is a subgraph of G induced by W if W is subset of V and F = (W,{u,y)|u,y in W and (u,y) in E)}) where u,y are edges , E is the set of all the edges in the graph, W is a set of nodes. 3)in the code implementation the nodes are named by integer numbers 1 ... n. 4) I suspect that the Vk is the set of nodes of the strong component K. now to the question. Lets say we have a graph G= (V,E) with V = {1,2,3,4,5,6,7,8,9} which it can be divided into 3 strong components the SC1 = {1,4,7,8} SC2= {2,3,9} SC3 = {5,6} (and their edges) Can anybody give me an example for s =1, s= 2, s= 5 what if going to be the Vk and Ak according to the code? The pseudo code is in my previous question in http://stackoverflow.com/questions/2908575/help-in-the-donalds-b-johnsons-algorithm-i-cannot-understand-the-pseudo-code and the paper can be found at http://stackoverflow.com/questions/2908575/help-in-the-donalds-b-johnsons-algorithm-i-cannot-understand-the-pseudo-code thank you in advance

  • How to recall search pattern when writing replace regex pattern in Vim?

    - by Tom Morris
    Here's the scenario: I've got a big file filled with all sorts of eclectic rubbish that I want to regex. I fiddle around and come up with a perfect search pattern by using the / command and seeing what it highlights. Now I want to use that pattern to replace with. So, I start typing :%s/ and I cannot recall what the pattern was. Is there some magical keyboard command that will pull in my last search pattern here? If I'm writing a particularly complex regex, I have even opened up a new MacVim window, typed the regex from the first window into a buffer there, then typed it back into the Vim window when writing the replace pattern. There has got to be a better way of doing so.

  • SLES 9 vs. SLES 10

    - by Michael Covelli
    Are there any important change in how SLES 10 implements Tcp sockets vs. SLES 9? I have several apps written in C# (.NET 3.5) that run on Windows XP and Windows Server 2003. They've been running fine for over a year, getting market data from a SLES 9 machine using a socket connection. The machine was upgraded today to SLES 10 and its causing some strange behavior. The socket normally returns a few hundred or thousand bytes every second. But occasionally, I stop receiving data. Ten or more seconds will go by with no data and then Receive returns with a 10k+ bytes. And some buffer is causing data loss because the bytes I receive on the socket no longer make a correct packet. The only thing changed was the SLES 9 to 10 upgrade. And rolling back fixes this immediately. Any ideas?

  • SSIS- Sharepoint list data transfer issue

    - by Vicky
    Hi , We are trying to transfer data from oracle database (about 60,0000) records only to a sharepoint list using SSIS. But we are getting following error when records reaches around 19000 . The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020 and System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (400) Bad Request. Earlier we thought if could because of Sharepoint list limit so we tried by reducing two of the columns and then it has went fine. So we left with one of the column of Datatype DT_STR and length 400 in oracle beacuse of which issue might be happening, It is mapped to sharepoint custom list field of multiline type. We also verified if length of field is issue but in oracle DB for all records max length for this column is only 239 so length issue is also ruled out. Any one who has faced this kind of issue or knows cause of this issue.Kindly let us know.. Thanks and regards, Vicky

  • How to gracefully exit SLIME and EMACS

    - by Gregory Gelfond
    Hi All, I have a question regarding how to "gracefully exit SLIME", when I quit Emacs. Here is the relevant portion of my config file: ;; SLIME configuration (setq inferior-lisp-program "/usr/local/bin/sbcl") (add-to-list 'load-path "~/Scripts/slime/") (require 'slime) (slime-setup) ;; configure SLIME to gracefully quit when emacs ;; terminates (defun slime-smart-quit () (interactive) (when (slime-connected-p) (if (equal (slime-machine-instance) "Gregory-Gelfonds-MacBook-Pro.local") (slime-quit-lisp) (slime-disconnect))) (slime-kill-all-buffers)) (add-hook 'kill-emacs-hook 'slime-smart-quit) To my knowledge this should automatically kill SLIME and it's associated processes whenever I exit Emacs. However, every time I exit, I still get the prompt: Proc Status Buffer Command ---- ------ ------ ------- SLIME Lisp open *cl-connection* (network stream connection to 127.0.0.1) inferior-lisp run *inferior-lisp* /usr/local/bin/sbcl Active processes exist; kill them and exit anyway? (yes or no) Can someone shed some insight as to what I'm missing from my config? Thanks in advance.

  • Adding audio channel using ffmpeg

    - by Raj
    Hi all, I am working on ffmpeg and trying to add a audio stream on the fly. I am using AudioQueues and I get raw audio buffer. I am encoding audio with linear PCM and hence the audio I get will be of raw format, which I know ffmpeg does accept it. But I cannot figure out how. I have looked into AVStream, where in we have to create a new stream for this audio channel but how do I encode it to a video which is already initialized in another AVStream structure. Overall, I would like to have an idea of the architecture of ffmpeg. I found it difficult to work since it is least documented. Any pointers or details are appreciated. Thanks and Regards, Raj Pawan G

  • help in the Donalds B. Johnson's algorithm, i cannot understand the pseudo code

    - by Pitelk
    Hi , does anyone know the Donald B. Johnson's algorithm which enumarates all the elementary circuits (cycles) in a Directed graph? link text I have the paper he had published in 1975 but I cannot understand the pseudo-code. My goal is to implement this algorithm in java. Some questions i have is for example what is the matrix Ak it refers to. In the pseudo code mentions that Ak:=adjacency structure of strong component K with least vertex in subgraph of G induced by {s,s+1,....n}; Does that mean i have to implement another algorithm that finds the Ak matrix? Another question is what the following means? begin logical f; Does also the line "logical procedure CIRCUIT (integer value v);" means that the circuit procedure returns a logical variable. In the pseudo code also has the line "CIRCUIT := f;" . Does this mean? It would be great if someone could translate this 1970's pseudocode to a more modern type of pseudo code so i can understand it in case you are interested to help but you cannot find the paper please email me at [email protected] and i will send you the paper. Thanks in advance

  • vim filters and stdout/stderr

    - by ahe
    When I use :%! to run the contents of a file through a filter and the filter fails (it returns another code than 0) and prints an error message to stderr I get my file replaced with this error message. Is there a way to tell vim to skip the filtering if the filter returns an status code that indicates an error and/or ignore output the filter program writes to stderr? There are cases where you want your file to replaced with the output of the filter but most often this behavior is wrong. Of course I can just undo the filtering with one keypress but it isn't optimal. Also I have a similar problem when writing a custom vim script to do the filtering. I have a script that calls a filter program with system() and replaces the file in the buffer with its output but there doesn't seem to be a way to detect if the lines returned by system() where written to stdout or to stderr. Is there a way to tell them apart in vim script?

  • Connect rails application to SQL Server 2005 from Windows

    - by Enrico Carlesso
    Hi guys. I (sadly) have to deploy a rails application on Windows XP which has to connect to Microsoft SQL Server 2005. Surfing in the web there are a lot of hits for connect from Linux to SQL Server, but cannot find out how to do it from Windows. Basically I followed these steps: Install dbi gem Install activerecord-sql-server-adapter gem My database.yml now looks like this: development: adapter: sqlserver mode: odbc dsn: test_dj host: HOSTNAME\SQLEXPRESS database: test_dj username: guest password: guest But I'm unable to connect it. When I run rake db:migrate I get IM002 (0) [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified I'm not a Windows user, so cannot understand really well the meaning of dsn element or so. Does someone have an idea how to solve this? Thanks in advance With Alexander tips now I've modified my database.yml to: development: adapter: sqlserver mode: odbc dsn: Provider=SQLOLEDB;Data Source=SCADA\SQLEXPRESS;UID=guest;PWD=guest;Initial Catalog=test_dj;Application Name=test But now rake db:migrate returns me: S1090 (0) [Microsoft][ODBC Driver Manager] Invalid string or buffer length Am I missing something?

  • Elisp performance on Windows and Linux

    - by JasonFruit
    I have the following dead simple elisp functions; the first removes the fill breaks from the current paragraph, and the second loops through the current document applying the first to each paragraph in turn, in effect removing all single line-breaks from the document. It runs fast on my low-spec Puppy Linux box using emacs 22.3 (10 seconds for 600 pages of Thomas Aquinas), but when I go to a powerful Windows XP machine with emacs 21.3, it takes almost an hour to do the same document. What can I do to make it run as well on the Windows machine with emacs 21.3? (defun remove-line-breaks () "Remove line endings in a paragraph." (interactive) (let ((fill-column 90002000)) (fill-paragraph nil))) : (defun remove-all-line-breaks () "Remove all single line-breaks in a document" (interactive) (while (not (= (point) (buffer-end 1))) (remove-line-breaks) (next-line 1))) Forgive my poor elisp; I'm having great fun learning Lisp and starting to use the power of emacs, but I'm new to it yet.

  • Referencing a union inside a structure using union tag gives incorrect address

    - by AlanKley
    I had a need to declare a union inside a structure as defined below: struct MyStruct { int m_DataType; DWORD m_DataLen; union theData { char m_Buff [_MAX_PATH]; struct MyData m_myData; } m_Data; }; Initially, I tried accessing the union data as follows (before I added the m_Data declaration): MyStruct m_myStruct; char* pBuff = m_myStruct.theData::m_Buff; This compiles but returns to pBuff a pointer to the beginning of the MyStruct structure which caused me to overwrite the m_DataType & m_DataLength members when I thought I was writing to the m_Buff buffer. I am using Visual Studio 2008. Can anyone explain this unexpected behavior? Thanks.

  • Unicode issue in Django

    - by Kave
    I seem to have a unicode problem with the deal_instance_name in the Deal model. It says: coercing to Unicode: need string or buffer, __proxy__ found The exception happens on this line: return smart_unicode(self.deal_type.deal_name) + _(u' - Set No.') + str(self.set) The line works if I remove smart_unicode(self.deal_type.deal_name) but why? Back then in Django 1.1 someone had the same problem on Stackoverflow I have tried both the unicode() as well as the new smart_unicode() without any joy. What could I be missing please? class Deal(models.Model): def __init__(self, *args, **kwargs): super(Deal, self).__init__(*args, **kwargs) self.deal_instance_name = self.__unicode__() deal_type = models.ForeignKey(DealType) deal_instance_name = models.CharField(_(u'Deal Name'), max_length=100) set = models.IntegerField(_(u'Set Number')) def __unicode__(self): return smart_unicode(self.deal_type.deal_name) + _(u' - Set No.') + str(self.set) class Meta: verbose_name = _(u'Deal') verbose_name_plural = _(u'Deals') Dealtype: class DealType(models.Model): deal_name = models.CharField(_(u'Deal Name'), max_length=40) deal_description = models.TextField(_(u'Deal Description'), blank=True) def __unicode__(self): return smart_unicode(self.deal_name) class Meta: verbose_name = _(u'Deal Type') verbose_name_plural = _(u'Deal Types')

  • Fastest Algorithm to scale down 32Bit RGB IMAGE.

    - by Sunny
    which algorithm to use to scale down 32Bit RGB IMAGE to custom resolution? Algorithm should average pixels. for example If I have 100x100 image and I want new Image of size 20x50. Avg of first five pixels of first source row will give first pixel of dest, And avg of first two pixels of first source column will give first dest column pixel. Currently what I do is first scale down in X resolution, and after that I scale down in Y resolution. I need one temp buffer in this method. Is there any optimized method that you know?

  • Lucene Error While Reading binary block : java.io.EOFException

    - by tushar Khairnar
    Hi, I am getting java.io.EOFException while reading a binary block from lucene index. I am storing java object as byte-array in lucene index field and reading it when hit occurs. Here is stack trace : Caused by: java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2281) at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2750) at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:780) at java.io.ObjectInputStream.(ObjectInputStream.java:280) at org.terracotta.modules.searchable.util.SerializationUtil$OIS.(SerializationUtil.java:20) I have some background threads which write into index. But i buffer them and then write them at once like 1000. Occasionally I also issue optimize() on index. When I write, I am re-opening IndexReader. Does this is happening because of IndexReader re-opening call? Thanks. Regards Tushar

  • Match multiline regex in file object

    - by williamx
    How can I extract the groups from this regex from a file object (data.txt)? import numpy as np import re import os ifile = open("data.txt",'r') # Regex pattern pattern = re.compile(r""" ^Time:(\d{2}:\d{2}:\d{2}) # Time: 12:34:56 at beginning of line \r{2} # Two carriage return \D+ # 1 or more non-digits storeU=(\d+\.\d+) \s uIx=(\d+) \s storeI=(-?\d+.\d+) \s iIx=(\d+) \s avgCI=(-?\d+.\d+) """, re.VERBOSE | re.MULTILINE) time = []; for line in ifile: match = re.search(pattern, line) if match: time.append(match.group(1)) The problem in the last part of the code, is that I iterate line by line, which obviously doesn't work with multiline regex. I have tried to use pattern.finditer(ifile) like this: for match in pattern.finditer(ifile): print match ... just to see if it works, but the finditer method requires a string or buffer. I have also tried this method, but can't get it to work matches = [m.groups() for m in pattern.finditer(ifile)] Any idea?

  • reading a BYTE as a DWORD in Masm

    - by Help I'm in college
    Hi, once again I'm doing MASM programming. I'm trying to write a procedure using the Irvine32 library where the user enters a string which is put into an array of BYTEs with ReadString. Then it loops over that arrray and determines if each character is a number. However, when I try cmp [buffer + ecx], 30h MASM complains about comparing two things that are not the same size. Is there anyway I could read the ASCII code in each BYTE in the array as a DWORD (or otherwise extract the ASCII value in each BYTE)?

  • How to escape HAML for Javascript in Sinatra

    - by viatropos
    I would like to return a list/combobox from an ajax request ("Which on of these do you like?" type thing). I would like to write that little snippet in HAML, which converts it to HTML, but when I do, the page goes blank. I'm assuming this is because the HTML isn't escaped. Is there a way to escape HAML so I can do $("#mydiv").html(response);? Here's the method: post "/something" do # process... haml :"partials/_select", :layout => false, :locals => {:collection => choices} end ... the haml template: %select - collection.each do |item| %option{:value => item.to_s}= item.to_s ... and the javascript: success: function(responseText, statusText, xhr, $form) { $(".dialog_content").append(responseText); } I have tried the sinatra_more plugin and the escape_javascript method, but there's problems with the haml buffer in sinatra. Any ideas?
