• Issues with SharePoint 2010 Development

  - by Rahul Soni

  I am planning to use my laptop for SharePoint 2010 development and I have only 4 GB RAM which is not even upgradable. Just because of RAM constraint, my VS 2010 keeps crawling if I try to run it along with SharePoint 2010 on the same machine. Hence, I've reformatted my machine and looking for alternate solutions until I get a new laptop. Currently, I have installed VS 2010 ONLY on my laptop and wanted to create an empty SharePoint project. Once done with my project, I want to deploy it on a different machine (which is a 4GB RAM machine as well, but contains only SharePoint 2010). I thought this will work and give me a bit of breather if everything is configured well. Unfortunately, when I tried creating a new SharePoint Empty Project in VS 2010, it says... A SharePoint server is not installed on this computer. A SharePoint server must be installed to work with SharePoint projects. Is there a way out?

• XSLT line counter - is it that hard?

  - by Mr AH

  I have cheated every time I've needed to do a line count in XSLT by using JScript, but in this case I can't do that. I simply want to write out a line counter throughout an output file. This basic example has a simple solution: <xsl:for-each select="Records/Record"> <xsl:value-of select="position()"/> </xsl:for-each> Output would be: 1 2 3 4 etc... But what if the structure is more complex with nested foreach's : <xsl:for-each select="Records/Record"> <xsl:value-of select="position()"/> <xsl:for-each select="Records/Record"> <xsl:value-of select="position()"/> </xsl:for-each> </xsl:for-each> Here, the inner foreach would just reset the counter (so you get 1, 1, 2, 3, 2, 1, 2, 3, 1, 2 etc). Does anyone know how I can output the position in the file (ie. a line count)?

• Intel GMA 4500MHD flickering in opengl

  - by Aaron

  I have an application that uses OpenGL for its display. When this application is run on a laptop with an Intel GMA 4500MHD on Windows XP the OpenGL content appears to flicker/shudder between 2 frames. I have experienced the exact same problem when running this application on nVidia Quadro FX hardware, however with nVidia the problem can be corrected by disabling the "Unified Back Buffer" (UBB) feature in the driver. Does anybody know how I can disable the corresponding feature in the Intel driver?

• pass other form elements to ajax suggestion box script

  - by Alex Calder

  I paid somebody to build me a jQuery AJAX suggestion box script a while back. It works great. Now I'm trying to learn about it enough to modify it to do something different. Right now, the script that generates the suggestions just takes the query text and does the same check every time. Now, I want to be able to pass along additional info so different things are looked for with each instance of a search box. The HTML... simple, obvious. input class="suggest" name="q" type="text" autocomplete="off" / The jQuery looks like this: jQuery(document).ready(function() { $('.suggest').autocomplete( { source:'output.php', minLength:3, focus: function (event, ui) { $(event.target).val(ui.item.label); return false; } } ); [snip] } Instead of: source:'output.php', minLength:3, I'd like: source:'output.php?arg1=blah1&arg2=blah2', minLength:3, where arg1 and arg2 are passed along in the form... input class="suggest" name="q" type="text" autocomplete="off" / input type="hidden" name="arg1" value="blah1" input type="hidden" name="arg2" value="blah2" Does this make sense? Thanks guys. I know just about "this much" about OOL's and javascript, so I'm learning... Alex

• log4net - why would the same MyLog.Debug line not work at one point of startup, but work at another

  - by Greg

  Hi, During startup of my WinForms application I'm noting that there are a couple of points (before the MainForm renders) that do a "MyDataSet.GetInstance()". For the first one the MyLog.Debug line comes through in the VS2008 output window, but for a later one it does work and come through. What could explain this? What settings could I check at debug time to see why an output line for a MyLog.Debug line doesn't come out in the output window? namespace IntranetSync { public class MyDataSet { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MyDataSet)); public static MyDataSet GetInstance() { MyLog.Debug("MyDataSet GetInstance() ====================================="); if (myDataSet == null) { myDataSet = new MyDataSet(); } return myDataSet; } . . . PS. What I have been doing re log4net repository initialization is putting the following line as a private variables in the classes I use logging - is this OK? static class Program { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MainForm)); . . . public class Coordinator { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MainForm)); . . . public class MyDataSet { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MyDataSet)); . . .

• How can I create a shortcut to uninstall MyApplication using the Visual Studio Installer?

  - by Coder7862396

  I have created an installer for MyApplication using the Visual Studio Installer (VSI) Setup Project. I would like to create a shortcut in the user's Start Menu to uninstall MyApplication (instead of having to go through the Add/Remove Programs control panel). I cannot simply create a batch/script file to run the command "msiexec /uninstall {MyGUID}" because, although it does succeed in running the uninstaller, when the uninstall completes the program folder (wherever the user has chosen to install the app) does not get deleted. It stays empty. How can I create a shortcut that can uninstall the program but not leave behind an empty program folder?

• Upsert - Efficient Update or Insert in VB.Net, SQL Server

  - by HK1

  I'm trying to understand how to streamline the process of inserting a record if none exists or updating a record if it already exists. I'm not using stored procedures, although maybe that would be the most efficient way of doing this. The actual scenario in which this is necessary is saving a user preference/setting to my SettingsUser table. In MS Access I would typically pull a DAO recordset looking for the specified setting. If the recordset comes back empty then I know I need to add a new record which I can do with the same recordset object. On the other hand, if it isn't empty, I can just update the setting's value right away. In theory, this is only two database operations. What is the recommended way of doing this in .NET?

• Find all paths from root to leaves of tree in Scheme

  - by grifaton

  Given a tree, I want to find the paths from the root to each leaf. So, for this tree: D / B / \ A E \ C-F-G has the following paths from root (A) to leaves (D, E, G): (A B D), (A B E), (A C F G) If I represent the tree above as (A (B D E) (C (F G))) then the function g does the trick: (define (g tree) (cond ((empty? tree) '()) ((pair? tree) (map (lambda (path) (if (pair? path) (cons (car tree) path) (cons (car tree) (list path)))) (map2 g (cdr tree)))) (else (list tree)))) (define (map2 fn lst) (if (empty? lst) '() (append (fn (car lst)) (map2 fn (cdr lst))))) But this looks all wrong. I've not had to do this kind of thinking for a while, but I feel there should be a neater way of doing it. Any ideas for a better solution (in any language) would be appreciated.

• Windows Media Center Buffering and Asus MyCinema U3100mini

  - by dsimcha

  I'm running an Asus MyCinema U3100mini ATSC on Windows 7 64-bit. When I play live TV in Windows Media Center, it's very choppy and uses 500+ MB of RAM, I'm guessing due to the hard drive buffering functionality. Is there any way to disable the live TV pause buffer completely? If not, can anyone recommend alternative software that: Works with the MyCinema. Is lightweight and not horribly bloated with features I'll never use like Windows Media Center is.

• OpenGL + cgFX Alpha Blending failure

  - by dopplex

  I have a shader that needs to additively blend to its output render target. While it had been fully implemented and working, I recently refactored and have done something that is causing the alpha blending to not work anymore. I'm pretty sure that the problem is somewhere in my calls to either OpenGL or cgfx - but I'm currently at a loss for where exactly the problem is, as everything looks like it is set up properly for alpha blending to occur. No OpenGL or cg framework errors are showing up, either. For some context, what I'm doing here is taking a buffer which contains screen position and luminance values for each pixel, copying it to a PBO, and using it as the vertex buffer for drawing GL_POINTS. Everything except for the alpha blending appears to be working as expected. I've confirmed both that the input vertex buffer has the correct values, and that my vertex and fragment shaders are outputting the points to the correct locations and with the correct luminance values. The way that I've arrived at the conclusion that the Alpha blending was broken is by making my vertex shader output every point to the same screen location and then setting the pixel shader to always output a value of float4(0.5) for that pixel. Invariably, the end color (dumped afterwards) ends up being float4(0.5). The confusing part is that as far as I can tell, everything is properly set for alpha blending to occur. The cgfx pass has the two following state assignments (among others - I'll put a full listing at the end): BlendEnable = true; BlendFunc = int2(One, One); This ought to be enough, since I am calling cgSetPassState() - and indeed, when I use glGets to check the values of GL_BLEND_SRC, GL_BLEND_DEST, GL_BLEND, and GL_BLEND_EQUATION they all look appropriate (GL_ONE, GL_ONE, GL_TRUE, and GL_FUNC_ADD). This check was done immediately after the draw call. I've been looking around to see if there's anything other than blending being enabled and the blending function being correctly set that would cause alpha blending not to occur, but without any luck. I considered that I could be doing something wrong with GL, but GL is telling me that blending is enabled. I doubt it's cgFX related (as otherwise the GL state wouldn't even be thinking it was enabled) but it still fails if I explicitly use GL calls to set the blend mode and enable it. Here's the trimmed down code for starting the cgfx pass and the draw call: CGtechnique renderTechnique = Filter->curTechnique; TEXUNITCHECK; CGpass pass = cgGetFirstPass(renderTechnique); TEXUNITCHECK; while (pass) { cgSetPassState(pass); cgUpdatePassParameters(pass); //drawFSPointQuadBuff((void*)PointQuad); drawFSPointQuadBuff((void*)LumPointBuffer); TEXUNITCHECK; cgResetPassState(pass); pass = cgGetNextPass(pass); }; and the function with the draw call: void drawFSPointQuadBuff(void* args) { PointBuffer* pointBuffer = (PointBuffer*)args; FBOERRCHECK; glClear(GL_COLOR_BUFFER_BIT); GLERRCHECK; glPointSize(1.0); GLERRCHECK; glEnableClientState(GL_VERTEX_ARRAY); GLERRCHECK; glEnable(GL_POINT_SMOOTH); if (pointBuffer-BufferObject) { glBindBufferARB(GL_ARRAY_BUFFER_ARB, (unsigned int)pointBuffer-BufData); glVertexPointer(pointBuffer-numComp, GL_FLOAT, 0, 0); } else { glVertexPointer(pointBuffer-numComp, GL_FLOAT, 0, pointBuffer-BufData); }; GLERRCHECK; glDrawArrays(GL_POINTS, 0, pointBuffer-numElem); GLboolean testBool; glGetBooleanv(GL_BLEND, &testBool); int iblendColor, iblendDest, iblendEquation, iblendSrc; glGetIntegerv(GL_BLEND_SRC, &iblendSrc); glGetIntegerv(GL_BLEND_DST, &iblendDest); glGetIntegerv(GL_BLEND_EQUATION, &iblendEquation); if (iblendEquation == GL_FUNC_ADD) { cerr << "Correct func" << endl; }; GLERRCHECK; if (pointBuffer-BufferObject) { glBindBufferARB(GL_ARRAY_BUFFER_ARB,0); } GLERRCHECK; glDisableClientState(GL_VERTEX_ARRAY); GLERRCHECK; }; Finally, here is the full state setting of the shader: AlphaTestEnable = false; DepthTestEnable = false; DepthMask = false; ColorMask = true; CullFaceEnable = false; BlendEnable = true; BlendFunc = int2(One, One); FragmentProgram = compile glslf std_PS(); VertexProgram = compile glslv bilatGridVS2();

• has_many association, nested models and callbacks

  - by fl00r

  Hi! I've got model A and model Attach. I'm editing my A form with nested attributes for :attaches. And when I am deleting all attaches from A via accepts_nested_attributes_for how can I get after_update/after_save callbacks for all of my nested models? Problem is that when I am executing callbacks in model A they are executed right AFTER model A is updated and BEFORE model Attach is updated, so I can't, for example, know if there is NO ANY attaches after I delete them all :). Look for example: my callback after_save :update_status won't work properly after I delete all of my attaches. model A after_save :update_status has_many :attaches accepts_nested_attributes_for :attaches, :reject_if => proc { |attributes| attributes['file'].blank? }, :allow_destroy => true def update_status print "\n\nOUPS! bag is empty!\n\n" if self.attaches.empty? end end model Attach belongs_to A end I am using rails 3 beta

• creating matrix with probabilities

  - by John Chan

  Hi all, I want to generate a matrix of NxN to test some code that I have where each row contains floats as the elements and has to add up to 1 (i.e. a row with a set of probabilities). Where it gets tricky is that I want to make sure that randomly some of the elements should be 0 (in fact most of the elements should be 0 except for some random ones to be the probabilities). I need the probabilities to be 1/m where m is the number of elements that are not 0 within a single row. I tried to think of ways to output this, but essentially I would need this stored in a C++ array. So even if I output to a file I would still have the issue of not having it in array as I need it. At the end of it all I need that array because I want to generate a Market Matrix file. I found an implementation in C++ to take an array and convert it to the market matrix file, so this is what I am basing my findings on. My input for the rest of the code takes in this market matrix file so I need that to be the primary form of output. The language does not matter, I just want to generate the file at the end (I found a way mmwrite and mmread in python as well) Please help, I am stuck and not really sure how to implement this.

• ADT will not allow creation of Android Activity

  - by NewShelbyWoo

  I installed the ADT bundle from http://developer.android.com/sdk/index.html yesterday, and I was following a basic Hello World tutorial. I created a new Android Application Project with a Blank Activity named MainActivity. The resulting project has an empty src folder and empty res\layout folder. There is a R.java file in the gen folder but it has no reference to MainActivity. This is what the SDK manager says I have installed Android SDK Tools v 22.6 Android SDK Platform-tools v 19.0.1 Android SDK Build-tools v 19 SDK Platform v 3 ARM EABI v7a System Image v 2 Android Support Library v 19.0.1 Google USB Driver v 9 I also tried manually creating an activity by right clicking the src folder and going to Android Activity, but when I hit Finish on the creation wizard, nothing happens. Does anyone have any clues as to what's going on? Did I miss a key component to install or something?

• Too many JavaScript and CSS files on my ASP.NET MVC 2 Master Page?

  - by Zack Peterson

  I'm using an EditorTemplate DateTime.ascx in my ASP.NET MVC 2 project. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime>" %> <%: Html.TextBox(String.Empty, Model.ToString("M/dd/yyyy h:mm tt")) %> <script type="text/javascript"> $(function () { $('#<%: ViewData.TemplateInfo.GetFullHtmlFieldId(String.Empty) %>').AnyTime_picker({ format: "%c/%d/%Y %l:%i %p" }); }); </script> This uses the Any+Time™ JavaScript library for jQuery by Andrew M. Andrews III. I've added those library files (anytimec.js and anytimec.css) to the <head> section of my master page. Rather than include these JavaScript and Cascading Style Sheet files on every page of my web site, how can I instead include the .js and .css files only on pages that need them--pages that edit a DateTime type value?

• Runing bcdedit from python in Windows 2008 SP2

  - by Lee-Man

  I do not know windows well, so that may explain my dilemma ... I am trying to run bcdedit in Windows 2008R2 from Python 2.6. My Python routine to run a command looks like this: def run_program(cmd_str): """Run the specified command, returning its output as an array of lines""" dprint("run_program(%s): entering" % cmd_str) cmd_args = cmd_str.split() subproc = subprocess.Popen(cmd_args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True) (outf, errf) = (subproc.stdout, subproc.stderr) olines = outf.readlines() elines = errf.readlines() if Options.debug: if elines: dprint('Error output:') for line in elines: dprint(line.rstrip()) if olines: dprint('Normal output:') for line in olines: dprint(line.rstrip()) errf.close() outf.close() res = subproc.wait() dprint('wait result=', res) return (res, olines) I call this function thusly: (res, o) = run_program('bcdedit /set {current} MSI forcedisable') This command works when I type it from a cmd window, and it works when I put it in a batch file and run it from a command window (as Administrator, of course). But when I run it from Python (as Administrator), Python claims it can't find the command, returning: bcdedit is not recognized as an internal or external command, operable program or batch file Also, if I trying running my batch file from Python (which works from the command line), it also fails. I've also tried it with the full path to bcdedit, with the same results. What is it about calling bcdedit from Python that makes it not found? Note that I can call other EXE files from Python, so I have some level of confidence that my Python code is sane ... but who knows. Any help would be most appreciated.

• How to compare 2 complex spreadsheets running in parallel for consistency with each other?

  - by tbone

  I am working on converting a large number of spreadsheets to use a new 3rd party data access library (converting from third party library #1 to third party library #2). fyi: a call to a UDF (user defined function) is placed in a cell, and when that is refreshed, it pulls the data into a pivot table below the formula. Both libraries behave the same and produce the same output, except, small irregularites can arise, such as an additional field being shown in the output pivot table using library #2, which can affect formulas on the sheet if data is being read from the pivot table without using GetPivotData. So I have ~100 of these very complicated (20+ worksheets per workbook) spreadsheets that I have to convert, and run in parallel for a period of time, to see if the output using the new data access library matches the old library. Is there some clever approach to do this, so I don't have to spend a large amount of time analyzing each sheet to determine the specific elements to compare? Two rough ideas that come to mind: 1. just create a Validator workbook that has the same # of worksheets, and simply do a Worbook1!Worksheet1!A1 - Worbook2!Worksheet3!A1 for every possible cell on each sheet 2. roughly the equivalent of #1, but just traverse the cells in the 2 books using VBA, and log any cells that do not match. I don't particularly like either idea, can anyone think of something better than this, maybe some 3rd party utility I could buy?

• Search resetting selection in tableview

  - by Jay

  I've got an NSTableView bound to an NSArrayController via content and selection indexes. All great so far - content displayed, etc. Now an NSSearchField is bound to the array controller via filterPredicate and the property of the array content instances that's to be searched. Searching/filtering the table view works great; table view showing only matching entries. However, searching resets the selection on the NSTableView if the existing selection isn't in the search results. Worse, not only during the search but after ending the search there's no selection on the table view. The NSArrayController is set up to Avoid Empty Selection. Any hints on how to properly configure bindings in this scenario to really prevent an empty selection much appreciated!

• Garbled text when constructing emails with vmime

  Hey, my Qt C++ program has a part where it needs to send the first 128 characters or so of the output of a bash command to an email address. The output from the tty is captured in a text box in my gui called textEdit_displayOutput and put into my message I built using the Message Builder ( the object m_vmMessage ) Here is the relevant code snippet: m_vmMessage.getTextPart()->setCharset( vmime::charsets::US_ASCII ); m_vmMessage.getTextPart()->setText( vmime::create < vmime::stringContentHandler > ( ui->textEdit_displayOutput->toPlainText().toStdString() ) ); vmime::ref < vmime::message > msg = m_vmMessage.construct(); vmime::utility::outputStreamAdapter out( std::cout ); msg->generate( out ); Giving bash 'ls /' and a newline makes vmime give terminal output like this: ls /=0Abin etc=09 initrd.img.old mnt=09 sbin=09 tmp=09 vmlinuz.o= ld=0Aboot farts=09 lib=09=09 opt=09 selinux usr=0Acdrom home=09 = lost+found=09 proc srv=09 var=0Adev initrd.img media=09 root = Whereas it should look more like this: ls / bin etc initrd.img.old mnt sbin tmp vmlinuz.old boot farts lib opt selinux usr cdrom home lost+found proc srv var dev initrd.img media root sys vmlinuz 18:22> How do I encode the email properly?

• python gui events out of order

  from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.

• youtube - video upload failure - unable to convert file - encoding the video wrong?

  - by Anthony

  I am using .NET to create a video uploading application. Although it's communicating with YouTube and uploading the file, the processing of that file fails. YouTube gives me the error message, "Upload failed (unable to convert video file)." This supposedly means that "your video is in a format that our converters don't recognize..." I have made attempts with two different videos, both of which upload and process fine when I do it manually. So I suspect that my code is a.) not encoding the video properly and/or b.) not sending my API request properly. Below is how I am constructing my API PUT request and encoding the video: Any suggestions on what the error could be would be appreciated. Thanks P.S. I'm not using the client library because my application will use the resumable upload feature. Thus, I am manually constructing my API requests.

  im installing django, the test for wsgi is ok, but when i point my default file to the django test, it doesnt work, this is the test that works fine: default: /etc/apache2/sites-available/default <VirtualHost *:80> ServerName www.example.com ServerAlias example.com ServerAdmin [email protected] DocumentRoot /var/www <Directory /var/www/documents> Order allow,deny Allow from all </Directory> WSGIScriptAlias / /home/ubuntu/djangoProj/micopiloto/application.wsgi <Directory /home/ubuntu/djangoProj/mysitio/wsgi_handler.py> Order allow,deny Allow from all </Directory> </VirtualHost> application.wsgi:: ~/djangoProj/micopiloto import os import sys sys.path.append('/srv/www/cucus/application') os.environ['PYTHON_EGG_CACHE'] = '/srv/www/cucus/.python-egg' def application(environ, start_response): status = '200 OK' output = 'Hello World!MK SS9 tkt kkk' response_headers = [('Content-type', 'text/plain'), ('Content-Length', str(len(output)))] start_response(status, response_headers) return [output] but if I change the default to point to application_sa.wsgi the django test, it doesnt work :( application_sa.wsgi import os, sys sys.path.append('/home/ubuntu/djangoProj/micopiloto') os.environ['DJANGO_SETTINGS_MODULE'] = 'micopiloto.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() I restart the apache server every time i change the wsgi to test, so what im i missing? thanks a lot!
