  • User control blank on form in VS 2008

    - by Eric
    I've created a user control that contains a table layout control with various other standard controls like buttons and labels. Yet when I add the user control to one of my forms the control is blank. I've tried building the solution and a see the user-control flicker as if it's being updated, but it remains blank. Also if I actually run the program the usercontrol can not be see on the form. I've used usercontrols like this in the past. Is there something I'm missing?

  • O'Reilly book clarification on 2d linear system

    - by Eric
    The Oreilly book "Learning openCV" states at page 356 : Quote Before we get totally lost, let’s consider a particular realistic situation of taking measurements on a car driving in a parking lot. We might imagine that the state of the car could be summarized by two position variables, x and y, and two velocities, vx and vy. These four variables would be the elements of the state vector xk. Th is suggests that the correct form for F is: x = [ x; y; vx; vy; ]k F = [ 1, 0, dt, 0; 0, 1, 0, dt; 0, 0, 1, 0; 0, 0, 0, 1; ] It seems natural to put 'dt' just there in the F matrix but I just don't get why. What if I have a n states system, how would I spray some "dt" in the F matrix?

  • Succinct But Complete Example of WPF App?

    - by Eric J.
    Is there a succinct but complete example project or tutorial that brings together the pieces of the Microsoft stack for a complete application? WPF MVVM Business Objects EF Database I find plenty for WPF and plenty for EF, but am having trouble fully understanding how the EF generated classes relate to business objects, and how those business objects in turn fit into the MVVM pattern.

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

  • Can I load the max value of the range attribute in CFINPUT using and AJAX call?

    - by Eric Belair
    I have a CFINPUT tag in a CFFORM: <cfinput type="text" id="itemInput" name="itemInput" /> I want to set the range dynamically without posting the page. I have several AJAX calls throughout the page to dynamically load form fields on the fly: <cfselect id="this" name="this" bind="cfc:Data.getThis()" bindonload="true" /> <cfselect id="that" name="that" bind="cfc:Data.getThat({p1})" /> <cfselect id="theOther" name="theOther" bind="cfc:Data.getTheOther({p1}, {p2})" /> <cfdiv id="maxQty" bind="cfc:Data.getMaxQty({itemId})" /> <cfinput type="text" id="qty" name="qty" /> <cfdiv id="itemId" bind="cfc:Data.getItemId({this}, {that}, {theOther})" /> In the above CFFORM, I basically want to set the minValue of the range to "1" and the maxValue of the range to the value of cfc:Data.getMaxQty({itemId}). Is this possible? How can I do it?

  • regressions with many nested categorical covariates

    - by eric
    I have a few hundred thousand measurements where the dependent variable is a probability, and would like to use logistic regression. However, the covariates I have are all categorical, and worse, are all nested. By this I mean that if a certain measurement has "city - Phoenix" then obviously it is certain to have "state - Arizona" and "country - U.S." I have four such factors - the most granular has some 20k levels, but if need be I could do without that one, I think. I also have a few non-nested categorical covariates (only four or so, with maybe three different levels each). What I am most interested in is prediction - given a new observation in some city, I would like to know the relevant probability/dependent variable. I am not interested as much in the related inferential machinery - standard deviations, etc - at least as of now. I am hoping I can afford to be sloppy. However, I would love to have that information unless it requires methods that are more computationally expensive. Does anyone have any advice on how to attack this? I have looked into mixed effects, but am not sure it is what I am looking for.

  • With the attachment_fu rails plugin, is there any way to delete files uploaded to Amazon S3?

    - by Eric Nguyen
    Let's say I'm using attachment_fu to attach profile pics to user profiles in a system, with Amazon S3 used as the actual file storage. When users upload new profile pics, I'd like to replace the attached file with the new one. I can do this within my database (i.e. the file metadata) easily, but attachment_fu doesn't seem to provide methods for deleting the files from S3. Am I missing something, or am I approaching this the wrong way? Many thanks!

  • Dealing with rapid tapping on Buttons

    - by Eric Burke
    I have a Button with an OnClickListener. For illustrative purposes, consider a button that shows a modal dialog: public class SomeActivity ... { protected void onCreate(Bundle state) { super.onCreate(state); findViewById(R.id.ok_button).setOnClickListener( new View.OnClickListener() { public void onClick(View v) { // This should block input new AlertDialog.Builder(SomeActivity.this) .setCancelable(true) .show(); } }); } Under normal usage, the alert dialog appears and blocks further input. Users must dismiss the dialog before they can tap the button again. But sometimes the button's OnClickListener is called twice before the dialog appears. You can duplicate this fairly easily by tapping really fast on the button. I generally have to try several times before it happens, but sooner or later I'll trigger multiple onClick(...) calls before the dialog blocks input. I see this behavior in Android 2.1 on the Motorola Droid phone. We've received 4 crash reports in the Market, indicating this occasionally happens to people. Depending on what our OnClickListeners do, this causes all sorts of havoc. How can we guarantee that blocking dialogs actually block input after the first tap?

  • How do I use compiler intrinsic __fmul_?

    - by Eric Thoma
    I am writing a massively parallel GPU application. I have been optimizing it by hand. I received a 20% performance increase with _fdividef(x, y), and according to The Cuda C Programming Guide (section C.2.1), using similar functions for multiplication and adding is also beneficial. The function is stated as this: "_fmulrn,rz,ru,rd". __fdividef(x,y) was not stated with the arguments in brackets. I was wondering, what are those brackets? If I run the simple code: int t = __fmul_(5,4); I a compiler error about how _fmul is undefined. I have the CUDA runtime included, so I don't think it is a setup thing; rather it is something to do with those square brackets. How do I correctly use this function? Thank you.

  • Instead of buying VS 2010 what options will you use for .net development in the future?

    - by Eric Neunaber
    Given the recent release of VS 2010 I was shocked to see the pricing structure for the different versions of the product. I was lucky enough to receive free versions of VS 2005 and 2008 from attending various MS events. For the hacking I do at home I'm not sure I'm going to spend the money to purchase the IDE and wanted to see what others were using. Like SharpDevelop MonoDevelop Expess Editions

  • Why do my horizontal toolstrips keep stacking verticaly?

    - by Eric
    I'm using a ToolStripContainer that contains three ToolStrips. At design time I move the ToolStrips to the positions I want them in, which is in a horizontal row across the top of the form like this: I then close and save the Form. However, if I open the form up again the ToolStrips end up stacked up on the left side of the ToolStripContainer like this: How can I keep the ToolStrips in the positions that I specify?

  • Putting together CSV Cells in Excel with a macro

    - by Eric Kinch
    So, I have a macro to export data into CSV format and it's working great (Code at the bottom). The problem is the data I am putting into it. When I put the data in question in it comes out Firstname,Lastname,username,password,description I'd like to change it so I get Firstname Lastname,Firstname,Lastname,username,password,description What I'd like to do is manipulate my existing macro so to accomplish this. I'm not so good at VBS so any input or a shove in the right direction would be fantastic. Thanks! Sub Make_CSV() Dim sFile As String Dim sPath As String Dim sLine As String Dim r As Integer Dim c As Integer r = 1 'Starting row of data sPath = "C:\CSVout\" sFile = "MyText_" & Format(Now, "YYYYMMDD_HHMMSS") & ".CSV" Close #1 Open sPath & sFile For Output As #1 Do Until IsEmpty(Range("A" & r)) 'You can also Do Until r = 17 (get the first 16 cells) sLine = "" c = 1 Do Until IsEmpty(Cells(1, c)) 'Number of Columns - You could use a FOR / NEXT loop instead sLine = sLine & """" & Replace(Cells(r, c), ";", ":") & """" & "," c = c + 1 Loop Print #1, Left(sLine, Len(sLine) - 1) 'Remove the trailing comma r = r + 1 Loop Close #1 End Sub

  • IE7 Times Out Debugging ASP.Net Page

    - by Eric J.
    My issue is similar to ASP.NET Debugging Timing out with IIS except that I'm using the built-in ASP.Net Development Server with VS 2010. If I pause for more than about 10 seconds in the debugger, IE7 "disconnects" from the web server with the error message Internet Explorer cannot display the webpage However, unlike in the similar question, the debugger is still running. If I refresh the browser it will post that refresh to the server and I can debug the page from the top again. Is it possible to configure things so that IE7 waits (much) longer before giving up? If it makes a difference, I'm launching IE using the "Start external program" option and passing a localhost URL as the command line argument (since Chrome is my default browser). I also specify a specific port.

  • How do I unhide a CFDIV that has dynamic content with AJAX binding itself?

    - by Eric Belair
    I have the following CFSELECT tags that are used to populate a text input: <cfselect id="this" name="this" bind="cfc:Data.getThis()" bindonload="true" /> <cfselect id="that" name="that" bind="cfc:Data.getThat({p1})" /> <cfselect id="theOther" name="theOther" bind="cfc:Data.getTheOther({p1}, {p2})" /> The text input is the only value that needs to be submitted in a form: <cfform name="addItem" method="post" action="somepage.cfm"> <cfinput type="text" id="item" name="item" bind="cfc:Data.getResult({this}, {that}, {theOther})" /><br /> <cfinput type="submit" name="addButton" value="Add Item" /> </cfform> I want the form and it's contents to be visible only when all three selections have been made, and there is a value for the text input. What is the best way to do this? I'm assuming some use of CFDIV is the best way, but I'm not sure how to load the dynamic content (the CFINPUTs) this way.

  • Which .NET performance and/or memory profilers will allow me to profile a DLL?

    - by Eric
    I write a lot of .NET based plug-ins for other programs which are usually compiled as a DLL which is up to the native application to start up. I've been using Equatec's profiler, which works great, but now would like something with more features, including the ability to profile memory usage. I tried out Red Gate's Ant Profiler, but as far as I can see there is no way to profile a DLL. The only option is to profile an EXE. So my question is what other profiling tools are available that will allow me to profile a single library DLL rather than an EXE. I'm assuming this would require injecting profile code into the library as Equatec does?

  • Integration Services Throws an Error Reading Access 2007 Table

    - by Eric Flamm
    [Participant Table [1994]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "I:\My Documents\Flamm Consulting\Migrations.accdb" failed with error code 0xC0209303. There may be error messages posted before this with more information on why the AcquireConnection method call failed. Frankly, I'm confused about how SSIS should connect to Access 2007 - the UI just isn't very friendly - there's no file browser, for example. I'm wondering if there's something wrong with my install - missing drivers, etc.

    Is there a good way to display the contents of a file as binary? I am creating a program that needs to save and load a 2D arrays from a files. When loading a saved file the result appears different. I need to be able to view the contents of the saved file in plain binary to tell if my problem in in my save or load function. Is there a program like octal dump but is binary dump? Thanks.

  • Excel workbooks produced by POI don't work when linked

    - by Eric Nicolas
    Here is what I'm doing : Create a workbook in memory (book = new HSSFWorkbook(), ...) Save it to disk (book.write(...)) Open in Excel (ok) Create another workbook in Excel, which links to the first one (=PoiWorkbook?xls!A1) Close Excel Then everytime I open the second workbook again, all the links are #N/A, unless I also open the POI-generated workbook at the same time. I never saw this behaviour with standard workbooks created in Excel. Anyone has seen this and found a workaround ? Thanks.

  • How do I read and traverse inodes

  • Using exponential smoothing with NaN values

    - by Eric
    I have a sample of some kind that can create somewhat noisy output. The sample is the result of some image processing from a camera, which indicates the heading of a blob of a certain color. It is an angle from around -45° to +45°, or a NaN, which means that the blob is not actually in view. In order to combat the noisy data, I felt that exponential smoothing would do the trick. However, I'm not sure how to handle the NaN values. On the one hand, involving them in the math would result in a NaN average, which would then prevent any meaningful results. On the other hand, ignoring NaN values completely would mean that a "no-detection" scenario would never be reported. And just to complicate things, the data is also noisy in that it can get false NaN value, which ideally would be smoothed somehow to prevent random noise. Any ideas about how I could implement such an exponential smoother?

  • Multiple word Auttosuggest using Lucene.Net

    - by eric
    I am currently working on an search application which uses Lucene.Net to index the data from the database to Index file. I have a product catalog which has Name, short and long description, sku and other fields. The data is stored in Index using StandardAnalyzer. I am trying to add auto suggestion for a text field and using TermEnum to get all the keyword terms and its score from the Index. But the terms returned are of single term. For example, if I type for co, the suggestion returned are costume, count, collection, cowboy, combination etc. But I want the suggestion to return phrases. For exmaple, if I search for co, the suggestions should be cowboy costume, costume for adults, combination locks etc. The following is the code used to get the suggestions: public string[] GetKeywords(string strSearchExp) { IndexReader rd = IndexReader.Open(mIndexLoc); TermEnum tenum = rd.Terms(new Term("Name", strSearchExp)); string[] strResult = new string[10]; int i = 0; Dictionary<string, double> KeywordList = new Dictionary<string, double>(); do { //terms = tenum.Term(); if (tenum.Term() != null) { //strResult[i] = terms.text.ToString(); KeywordList.Add(tenum.Term().text.ToString(), tenum.DocFreq()); } } while (tenum.Next() && tenum.Term().text.StartsWith(strSearchExp) && tenum.Term().text.Length > 1); var sortedDict = (from entry in KeywordList orderby entry.Value descending select entry); foreach (KeyValuePair<string, double> data in sortedDict) { if (data.Key.Length > 1) { strResult[i] = data.Key; i++; } if (i >= 10) //Exit the for Loop if the count exceeds 10 break; } tenum.Close(); rd.Close(); return strResult; } Can anyone please give me directions to achive this? Thanks for looking into this.
