• Problem using SQLDMO/Vb6 against SQL Server 2008

  - by E.J. Brennan

  I have a client, that uses SQLDMO for a portion of a custom application that was written against SQL Server 2000, and they recently upgraded to SQL Server 2008. The majority of the app still runs fine (doesn't use SQLDMO), but the admin functions which rely on SQLDMO stopped working. I installed the SQL2005 backward compatibility pack, and now SQLDMO partially works, i.e. I can run "select" type queries, but any "Update" queries fail with the error message: to connect to the server you must use SQL Server management studio or sql server management objects (SMO) Any thoughts? Should the backward compatibility pack give me ALL the functionality back, or is this a known issue? BTW: I realize SQLDMO has been deprecated and will go away next release, none-the-less I need to do what I can to solve the problem at hand.

• PLT Scheme Extracting field ids from structures

  - by Steve Knight

  I want to see if I can map PLT Scheme structure fields to columns in a DB. I've figured out how to extract accessor functions from structures in PLT scheme using the fourth return value of: (struct-type-info) However the returned procedure indexes into the struct using an integer. Is there some way that I can find out what the field names were at point of definition? Looking at the documentation it seems like this information is "forgotten" after the structure is defined and exists only via the generated-accessor functions: (<id>-<field-id> s). So I can think of two possible solutions: Search the namespace symbols for ones that start with my struct name (yuk); Define a custom define-struct macro that captures the ordered sequence of field-names inside some hash that is keyed by struct name (eek).

• Performance of DrawingVisual vs Canvas.OnRender for lots of constantly changing shapes

  - by romkyns

  I'm working on a game-like app which has up to a thousand shapes (ellipses and lines) that constantly change at 60fps. Having read an excellent article on rendering many moving shapes, I implemented this using a custom Canvas descendant that overrides OnRender to do the drawing via a DrawingContext. The performance is quite reasonable, although the CPU usage stays high. However, the article suggests that the most efficient approach for constantly moving shapes is to use lots of DrawingVisual instances instead of OnRender. Unfortunately though it doesn't explain why that should be faster for this scenario. Changing the implementation in this way is not a small effort, so I'd like to understand the reasons and whether they are applicable to me before deciding to make the switch. Why could the DrawingVisual approach result in lower CPU usage than the OnRender approach in this scenario?

• UITableView resizing rows problem

  - by Vin

  Hi All, Hope to get solution to this problem. I have been stuck on it since a long time now. I have a a tableView which has custom labels drawn upon the cell using CGRect. I receive the data from a web service in arrays. Initially i display a line of data on the cells. When the user selects a cell, I call reloadsRowAtIndexPath to increase the height of selected row. In the process, cellForRowAtIndexPath gets called again. I keep track of this by a flag, and when cellForRowAtIndexPath gets called again, I display the two more lines of data from arrays, on the cell. What i am getting is all overlapping data on one other. I tried to remove already placed labels in didSelectRowAtIndexPath, but to no avail. Please help me on this Thanks in advance.

• Execute a function when a <link> element has finished loading

  - by nornagon

  I'm using jQuery Masonry to lay out my page, but I'm using a custom @font-face font. The problem being that Masonry doesn't know the metrics of the font until it's loaded. The Masonry docs suggest that you use $(window).load() instead of $(document).ready() to call the layout functions, but I don't want to have to wait until all the images etc. load. I can specify the dimensions of the images exactly, so Masonry doesn't need to wait until they're loaded. It's just the text that's the problem. How can I get jQuery to call a callback when the <link> element that links in the font finishes loading?

• mybase.showdialog event fired without apparent reason

  - by António Mendes

  Hi, i'm new to vb .net and oop although i have learned the basics. I'm working in VB and .NET CF 3.5 and i'm trying to pass and received a value with showdialog. The issue here is when i'm done with a procedure in Load, for some reason MyBase.Showdialog (line 3) gives an error of "NullReferenceException was unhandled", but the same procedure doesn't have anything to do with Showdialog. Also, this same error happens with me in other forms when i use AlphaImageButton from AlphaMobileControls. I even created an custom AlphaImageButton with a DialogResult Property and set it to None with no avail. Public Overloads Function ShowDialog(ByRef sArg As String) As String sParam = Split(sArg, vbTab) sArtigo = sParam(0) If MyBase.ShowDialog() = Windows.Forms.DialogResult.OK Then Return lblQuant.Text End If Return Nothing End Function

• Handling database failover for Rails applications on FreeBSD

  - by bianster

  I'm working on implementing database (Postgresql) failover for a Rails app that runs with Passenger/FreeBSD. Due to certain constraints regarding the server OS, it's necessary to continue using FreeBSD (as opposed to say, Ubuntu). I'm finding it to be quite a challenge to have failover handled within the Rails application, by way of a customised database adapter due to the fact that this application will be load-balanced between several webservers, and the multiple Rails processes that Passenger spawned in each webserver. I previously looked at setting up Pacemaker/Corosync to manage database server failover on a common IP but unfortunately I wasn't able to get past building the packages on FreeBSD. It does work rather well on Ubuntu 10.04 but I'm not likely to be able to use Ubuntu due to the OS constraints. I'm considering a custom witness daemon that simply pings the primary DB server, and this witness daemon switches all the webservers to the standby DB server when the primary becomes uncontactable (permanently/temporarily), to avoid split-brain. Though I would really like to know if there is a way to get Pacemaker(or something similar) to do the switch on FreeBSD.

• Repeater itemdatabound event value type and reference type

  - by Sune

  Im trying to bind a list with datetime objects to my repeater. if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item) { DateTime actualDate = e.Item.DataItem as DateTime; } When I want access the itemdatabound event on the repeater Then I get an errormessage which says that DateTime is a valuetype and not a reference type. My solution is that a wrap the datetime in a custom object (reference type) and pass that to the repeater datasource instead of the datetime. But Im wondering if there are other solutions where the repeater takes valuetypes (DateTime objects)........

• MS Web Browser on Pocket PC

  - by PoweRoy

  Hi all, I'm trying to create a custom web browser for on a pocket pc in C++ MFC. When I add the Microsoft Web Browser activeX control and run the app on the pocket pc (emulator) then this error pops up: "Debug assertion failed. occcont.cpp line: 916" When I look in the debug window of VS2005: "CoCreateInstance of OLE control {8856F961-340A-11D0-A96B-00C04FD705A2} failed. Result code: 0x80040154 Is the control is properly registered? Warning: Resource items and Win32 Z-order lists are out of sync. Tab order may be not defined well." How can I use this control on a pocket pc? Or is there a similar control that works?

• Using IVMRWindowlessControl to display video in a Winforms Control and allow for full screen toggle

  - by Jonathan Websdale

  I've recently switched from using the IVideoWindow interface to IVMRWindowlessControl in my custom Winforms control to display video. The reason for this was to allow zoom capabilities on the video within the control. However in switching over, I've found that the FullScreen mode from IVideoWindow is not available and I am currently trying to replicate this using the SetVideoWindow() method. I'm finding that I size the video in my control to be at the same resolution as the screen however I can't get the control to position itself to the top/left of the screen and become the top most window. Any ideas on how to achieve this since the IVideoWindow::put_FullScreenMode just did it all for you?

• Zend RegEx Validator error message issue

  - by Mallika Iyer

  Hello, I'm validating a text field in my form as follows: $name = new Zend_Form_Element_Text('name'); $name->setLabel('First Name:') ->setRequired(true) ->addFilter(new Zend_Filter_StringTrim()) ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/')) ->addErrorMessage('Please enter a valid first name'); What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.' Is there a way I can access what character the regex is failing for? Would you recommend something else altogether? I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere. If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user. I'd appreciate your inputs.

• Dump characters (glyphs) from TrueType font (TTF) into bitmaps

  - by jpatokal

  I have a custom TrueType font (TTF) that consists of a bunch of icons, which I'd like to render as individual bitmaps (GIF, PNG, whatever) for use on the Web. You'd think this is a simple task, but apparently not? There is a huge slew of TTF-related software here: http://cg.scs.carleton.ca/~luc/ttsoftware.html But it's all varying levels of "not quite what I want", broken links and/or hard to impossible to compile on a modern Ubuntu box -- eg. dumpglyphs (C++) and ttfgif (C) both fail to compile due to obscure missing dependencies. Any ideas?

• When to use UserControl vs. Control in Silverlight?

  - by Dov

  I'm just getting my feet wet in Silverlight, and don't really understand the differences and pros/cons of creating a UserControl vs. creating a Control for the same task (as in when you right click on a selection in Expression Blend, for instance). It seems like selecting "Make Into Control" just creates a new template for the base type you specify, whereas creating a UserControl creates a whole new base class. Is that correct? In this particular instance, I'm creating a custom text box control that only takes numbers, and divides itself into 3 sections, storing 3 values into separate properties as pictured below. In this particular case, which would be best? Update (Additional Question): Why can't I use Template Binding with a UserControl, but I can with a Control? That's one reason I thought that making a UserControl might not be the right decision.

• Silverlight chart with behavior/bitmap image tooltip passthrough

  - by isitdanny

  I have a chart showing bound data as tooltips and it works well. I have added a magnifier(set of behaviors class) that captures a bitmap image at two times scale that shows in a circular area over the hover spot. The tooltip does not display. I have tried a custom tooltip service but cannot bind it to the behaviors. I added the tooltip to the behavior class and got a tooltip and data but could not move it with the magnifier. It just sits in the middle and laughs. I added a usercontrol "tooltip"-same issues, could not hook it to the magnifier behavior. I know I can probably build a popup, but really wanted to just pass through the bitmap layer with the tootip. Any ideas would be greatly appreciated. Danny

• Personalization in ASP.Net MVC -- friendly URLs, and skinning

  - by larryq

  Hi everyone, I haven't delved into custom generation of friendly URLs in ASP.Net MVC, and was wondering if anyone had suggestions. For example, if John Smith were to create an account on www.example.com, I'd like for his homepage to read www.example.com/JohnSmith -- along with the option for him to choose his URL. The ideal is for this to happen with no intervention on my part in the route maps. Also, does anyone have guidelines on good ways to go to customize an MVC site based on URL? Again, using example.com I'd like for John to choose a color theme and logo for his homepage, then apply it accordingly. Thanks for your tips and suggestions.

• Horizontal "tab"ish scroll between views

  - by Steve Pomeroy

  I'm interested in creating a horizontal scroll view that "snaps" to the viewed item, so only one item is ever shown at a time. The user can touch-drag left/right and will see previous/next views, switching to it if there's enough velocity. This interaction is exactly like what the new weather/news widget that comes with the Nexus One does for navigating between its "tabs". Are there any existing view widgets that do this? Update: found a copy of the news/weather widget (GenieWidget) and they seem to have implemented their own widget to accomplish this which they call com.google.android.apps.genie.geniewidget.ui.FlingableLinearLayout which is part of their own custom com.google.android.apps.genie.geniewidget.ui.TabView. As that source isn't available, that's not looking too hopeful a direction.

• Have VB.Net 2010 ErrorProvider Fire on Tabbing Out of BindingSource TextBox on a WinForm

  - by OneSource

  I have a TextBox control on a Windows Form that uses a DataSource custom object as its BindingSource. I have associated an ErrorProvider with the BindingSource like so: Dim dobExample As New DOExample ExampleBS.DataSource = dobExample epExample.DataSource = ExampleBS The ErrorProvider fires if I type a blank space in the TextBox and then press Tab to move to the next control, which is correct. But it doesn't fire if I just press Tab without entering anything. I want the ErrorProvider to show the Error, even if the TextBox is empty and not just validate when there is text in the TextBox. How do I accomplish this? As an additional bit of info, when I execute the following statement: epDOContact.GetError(TextBox) an empty string is returned even though the TextBox is empty when it is required to be present.

• Interpretation of empty User-agent

  - by Amit Agrawal

  How should I interpret a empty User-agent? I have some custom analytics code and that code has to analyze only human traffic. I have got a working list of User-agents denoting human traffic, and bot traffic, but the empty User-agent is proving to be problematic. And I am getting lots of traffic with empty user agent - 10%. Additionally - I have crafted the human traffic versus bot traffic user agent list by analyzing my current logs. As such I might be missing a lot of entries in there. Is there a well maintained list of user agents denoting bot traffic, OR the inverse a list of user agents denoting human traffic?

• Keep an object for the time the connection is running in ASP.NET

  - by vtortola

  Hi, I'm developing a web service with ASP.NET, is not an .asmx or WCF, it's a custom one, so I'm working with the Http classes (context, request, response, etc..). Session is disabled. I'm working with my own handler and module. I'd like to keep a object alive and accessible for the time the connection is alive. I mean, a request enters, I assign a DbCommand to it and that connection will use that command as long is doing things, when that connection is ended, the object should be disposed. I've thought, that I can add it to my IPrincipal implementation, then when the connection is authenticated in the module and the user retrieved, I can add that DbCommand to the IPrincipal, so I can retrieve it from wherever I want in the code, and after in the module EndRequest event, I can dispose it, but I don't know if there is a better approach to do this. What do you think? cheers

• 3rd party data - Store in Data Warehouse or Primary database?

  - by brydgesk

  This is mostly a data warehouse philosophy question. My project involves an Oracle forms application, and a Teradata Data Warehouse for reporting and ad-hoc purposes. In addition to the primary data created by the users of our application, we also require data from various other sources. Currently, this 3rd party data comes via FTPd flat files directly to our Data Warehouse. To access the data, our users must use a series of custom BusinessObjects reports. My question is, would it make more sense for this data to be sent to our source Oracle system instead? Is it ever appropriate for a Data Warehouse to be the point of origin for users to access raw data? In short, is it more important that the operational database contain only the data created by your project, or that the data warehouse remain dedicated solely to reporting and analysis?

• How can a Delphi TForm / TPersistent object calculate its own construction and deserialization time?

  - by mjustin

  For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions. Background: for some of our app forms which have a very basic structure (with some PageControls and QuantumGrids) I realized that it is not database access and other stuff in OnFormShow but the construction which took most of the time (around 2 seconds) which makes me wonder where this time is spent. As a reference object I will also build a mock form which has a similar structure but no code or datamodule connections and measure its creation time.

• What should I use for the filepath if I'm developing from my desktop?

  - by codeninja

  I'm having an extremely difficulty time getting the flowplayer to show up and the worst part is I have no idea what is wrong because I'm not getting any error messages! I have an external javascript file: C:/desktop/mysite/js/jq/plugins.js calling $f() from: C:/desktop/mysite/thirdparty/flowplayer/flowplayer.js the swf files also live there... I'm working on file/desktop (no localhost or webserver) $(video.id).flowplayer("thirdparty/flowplayer/flowplayer-3.1.15.swf", { clip:{ .... }, // min Flash version version:[9,115], // older versions will see a custom message onFail:function(){ alert("Failed!"); }, onError:function(errCode,errMsg){ alert(errCode+errMsg); } }); I don't know what path to use for the SWFs to get them to load, is the path relative to the javascript (plugins.js) that calls $f() or is it relative to the path of the flowplayer.js ?? bangs head on wall

• Android: No icon for Notification

  - by Omer

  Hello, I wanted to create a notification without the icon in the status bar (the state that is not expanded). I tried the custom expanded view and set the icon for this view only. But it did not work. When I give 0 as icon to the constructor, the icon disappears but notification also does not appear in the expanded view. Notification notification = new Notification(0, "", 0); I tried a lot of combinations but didn't come out with a solution. By the way, I know it is working because I saw this feature in some apps. Thanks.

• Calling "function" on control

  - by Sascha

  Hi, I'm using MVVM in my WPF project. Now I want to display a subwindow when someone presses a button. To achieve this classically I would call the Show() method. What I want now, to keep my application clear, is to bind the button to the Show() function of the subwindow. As the button click (menu click, whatever) is not always allowed I wrote a custom command that evaluates if the command can be executed. However, I did not found a clue how to call the function of that control in a clean way. Is this the point to do some classic style (code in the frontend)? -sa
