  • Delphi TBytesField - How to see the text properly - Source is HIT OLEDB AS400

    - by myitanalyst
    We are connecting to a multi-member AS400 iSeries table via HIT OLEDB and HIT ODBC. You connect to this table via an alias to access a specific multi-member. We create the alias on the AS400 this way: CREATE ALIAS aliasname FOR table(membername) We can then query each member of the table this way: SELECT * FROM aliasname We are testing this in Delphi6 first, but will move it to D2010 later We are using HIT OLEDB for the AS400. We are pulling down records from a table and the field is being seen as a tBytesField. I have also tried ODBC driver and it sees as tBytesField as well. Directly on the AS400 I can query the data and see readable text. I can use the iSeries Navigation tool and see readable text as well. However when I bring it down to the Delphi client via the HIT OLEDB or HIT ODBC and try to view via asString then I just see unreadable text.. something like this: ñðð@ðõñððððñ÷@õôððõñòøóóöøñðÂÁÕÒ@ÖÆ@ÁÔÅÙÉÃÁ@@@@@@@@ÂÈÙÉâãæÁðòñè@ÔK@k@ÉÕÃK@@@@@@@@@ç I jumbled up the text above, but that is the character types that show up. When I did a test in D2010 the text looks like japanse or chinese characters, but if I display as AnsiString then it looks like what it does in Delphi 6. I am thinking this may have something to do with code pages or character sets, but I have no experience in this are so it is new to me if it is related. When I look at the Coded Character Set on the AS400 it is set to 65535. What do I need to do to make this text readable? We do have a third party component (Delphi400) that makes things behave in a more native AS400 manner. When I use its AS400 connection and AS400 query components it shows the field as a tStringField and displays just fine. BUT we are phasing out this product (for a number of reasons) and would really like the OLEDB with the ADO components work. Just for clarification the HIT OLEDB with tADOQuery do have some fields showing as tStringFields for many of the other tables we use... not sure why it is showing as a tBytesField in this case. I am not an AS400 expert, but looking at the field definititions on the AS400 the ones showing up as tBytesField look the same as the ones showing up as tStringFields... but there must be a difference. Maybe due to being a multi-member? So... does anyone have any guidance on how to get the correct string data that is readable? If you need more info please ask. Greg

  • WPF Converter and NotifyOnTargetUpdated exclusive in a binding ?

    - by Mathieu Garstecki
    Hi, I have a problem with a databinding in WPF. When I try to use a value converter and set the NotifyOnTargetUpdated=True property to True, I get an XamlParseException with the following message: 'System.Windows.Data.BindingExpression' value cannot be assigned to property 'Contenu' of object 'View.UserControls.ShadowedText'. Value cannot be null. Parameter name: textToFormat Error at object 'System.Windows.Data.Binding' in markup file 'View.UserControls;component/saletotal.xaml' Line 363 Position 95. The binding is pretty standard: <my:ShadowedText Contenu="{Binding Path=Total, Converter={StaticResource CurrencyToStringConverter}, NotifyOnTargetUpdated=True}" TargetUpdated="MontantTotal_TargetUpdated"> </my:ShadowedText> (Styling properties removed for conciseness) The converter exists in the resources and works correctly when NotifyOnTargetUpdated=True is removed. Similarly, the TargetUpdated event is called and implemented correctly, and works when the converter is removed. Note: This binding is defined in a ControlTemplate, though I don't think that is relevant to the problem. Can anybody explain me what is happening ? Am I defining the binding wrong ? Are those features mutually exclusive (and in this case, can you explain why it is so) ? Thanks in advance. More info: Here is the content of the TargetUpdated handler: private void MontantTotal_TargetUpdated(object sender, DataTransferEventArgs e) { ShadowedText textBlock = (ShadowedText)e.TargetObject; double textSize = textBlock.Taille; double delta = 5; double defaultTaille = 56; double maxWidth = textBlock.MaxWidth; while (true) { FormattedText newFormat = new FormattedText(textBlock.Contenu, CultureInfo.CurrentCulture, FlowDirection.LeftToRight, new Typeface("Calibri"), textSize, (SolidColorBrush) Resources["RougeVif"]); if (newFormat.Width < textBlock.MaxWidth && textSize <= defaultTaille) { if ((Math.Round(newFormat.Width) + delta) >= maxWidth || textSize == defaultTaille) { break; } textSize++; } else { if ((Math.Round(newFormat.Width) - delta) <= maxWidth && textSize <= defaultTaille) { break; } textSize--; } } textBlock.Taille = textSize; } The role of the handler is to resize the control based on the length of the content. It is quite ugly but I want to have the functional part working before refactoring.

  • .NET Interface with AutoCAD -- SetXData errors.

    - by Jerry
    I am trying to use the SetXData method on the AutoCAD 2007 COM object, but it is throwing errors. Example Test: public AcadEntity getAcadEntity() { /// ... Basic code to return a single AutoCAD entity... } private void btnTagItem_Click(object sender, EventArgs e) { AcadEntity ent = getAcadEntity(); short[] xDataType; string[] xDataStrings; DrawingXData xData = new DrawingXData(); xData.field1 = "Some Text Goes here"; xData.field2 = 1; xData.field3 = 100; xData.field4 = 1509.2; xData.field5 = "More Text"; BuildXData("AutoCad_App_Name", xData, out xDataType, out xDataStrings); ent.SetXData(xDataType, xDataStrings); // This line crashes. } private void BuildXData(string applicationName, DrawingXData xData, out short[] xDataType, out string[] xDataStrings) { List<short> dataTypes = new List<short>(); List<string> dataStrings = new List<string>(); /// Code types... /// 1000 == String up to 255 bytes /// 1001 == Application Name // Set Applicaiton Name dataTypes.Add(1001); dataStrings.Add(applicationName); // Set Application Data dataTypes.Add(1000); dataStrings.Add(xData.field1.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field2.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field3.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field4.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field5.ToString()); // ... etc. xDataType = dataTypes.ToArray(); xDataStrings = dataStrings.ToArray(); } The error I get is "Invalid argument data in SetXData method". The error code (if this helps anyone) is -2145320939. The main reason I'm posting is because the same code in a very old VB6 application works just fine. I'm stumped.

  • Expand and Shrink UIScrollView with animation

    - by Dilip Rajkumar
    I am having a UITableView inside a scrollview. So I am trying to do a accordion like component using UITableView. So I need to expand the UITableView to add more cell. In that case I have to increase the height of UIScrollView with a animation so that it matches the table animation. - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSInteger row = [indexPath row]; BOOL preventReopen = NO; if (row == expandedRowIndex + 1 && expandedRowIndex != -1) return nil; [tableView beginUpdates]; if (expandedRowIndex != -1) { familyTableView.frame = CGRectMake(familyTableView.frame.origin.x, familyTableView.frame.origin.y, familyTableView.frame.size.width, 3*50+22); toolsTableView.frame = CGRectMake(toolsTableView.frame.origin.x, familyTableView.frame.origin.y + familyTableView.frame.size.height + 20, toolsTableView.frame.size.width, 4*50+22); myAccountTableView.frame = CGRectMake(myAccountTableView.frame.origin.x, toolsTableView.frame.origin.y + toolsTableView.frame.size.height + 20, myAccountTableView.frame.size.width, 2*50+22); settingsScrollView.contentSize = CGSizeMake(320, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380); settingsScrollView.contentInset = UIEdgeInsetsMake(0, 0, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380, 0); NSInteger rowToRemove = expandedRowIndex + 1; preventReopen = row == expandedRowIndex; if (row > expandedRowIndex) row--; expandedRowIndex = -1; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:rowToRemove inSection:0]] withRowAnimation:UITableViewRowAnimationTop]; }else { familyTableView.frame = CGRectMake(familyTableView.frame.origin.x, familyTableView.frame.origin.y, familyTableView.frame.size.width, (3*50+22) + 100); toolsTableView.frame = CGRectMake(toolsTableView.frame.origin.x, familyTableView.frame.origin.y + familyTableView.frame.size.height + 20, toolsTableView.frame.size.width, 4*50+22); myAccountTableView.frame = CGRectMake(myAccountTableView.frame.origin.x, toolsTableView.frame.origin.y + toolsTableView.frame.size.height + 20, myAccountTableView.frame.size.width, 2*50+22); settingsScrollView.contentSize = CGSizeMake(320, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380); settingsScrollView.contentInset = UIEdgeInsetsMake(0, 0, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380, 0); } NSInteger rowToAdd = -1; if (!preventReopen) { rowToAdd = row + 1; expandedRowIndex = row; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:rowToAdd inSection:0]] withRowAnimation:UITableViewRowAnimationTop]; } [tableView endUpdates]; return nil; } I am not good at animation. Any help is greatly appreciated. What I need is when we do [tableView beginUpdates] we have to start animating the resize effect to UIScrollView and it should end when [tableView endUpdates] executes. So the Accordion executes flawlessly. Thanks in advance for any help..

Is there a way to disable this functionality, or at least bypass this error? I have already provided implementation for a MultipartWrapperFactory.Class as that has been suggested from searching for this error Thanks

  • C# Silverlight - Delay Child Window Load?!

    - by Goober
    The Scenario Currently I have a C# Silverlight Application That uses the domainservice class and the ADO.Net Entity Framework to communicate with my database. I want to load a child window upon clicking a button with some data that I retrieve from a server-side query to the database. The Process The first part of this process involves two load operations to load separate data from 2 tables. The next part of the process involves combining those lists of data to display in a listbox. The Problem The problem with this is that the first two asynchronous load operations haven't returned the data by the time the section of code to combine these lists of data is reached, thus result in a null value exception..... Initial Load Operations To Get The Data: public void LoadAudits(Guid jobID) { var context = new InmZenDomainContext(); var imageLoadOperation = context.Load(context.GetImageByIDQuery(jobID)); imageLoadOperation.Completed += (sender3, e3) => { imageList = ((LoadOperation<InmZen.Web.Image>)sender3).Entities.ToList(); }; var auditLoadOperation = context.Load(context.GetAuditByJobIDQuery(jobID)); auditLoadOperation.Completed += (sender2, e2) => { auditList = ((LoadOperation<Audit>)sender2).Entities.ToList(); }; } I Then Want To Execute This Immediately: IEnumerable<JobImageAudit> jobImageAuditList = from a in auditList join ai in imageList on a.ImageID equals ai.ImageID select new JobImageAudit { JobID = a.JobID, ImageID = a.ImageID.Value, CreatedBy = a.CreatedBy, CreatedDate = a.CreatedDate, Comment = a.Comment, LowResUrl = ai.LowResUrl, }; auditTrailList.ItemsSource = jobImageAuditList; However I can't because the async calls haven't returned with the data yet... Thus I have to do this (Perform the Load Operations, Then Press A Button On The Child Window To Execute The List Concatenation and binding): private void LoadAuditsButton_Click(object sender, RoutedEventArgs e) { IEnumerable<JobImageAudit> jobImageAuditList = from a in auditList join ai in imageList on a.ImageID equals ai.ImageID select new JobImageAudit { JobID = a.JobID, ImageID = a.ImageID.Value, CreatedBy = a.CreatedBy, CreatedDate = a.CreatedDate, Comment = a.Comment, LowResUrl = ai.LowResUrl, }; auditTrailList.ItemsSource = jobImageAuditList; } Potential Ideas for Solutions: Delay the child window displaying somehow? Potentially use DomainDataSource and the Activity Load control?! Any thoughts, help, solutions, samples comments etc. greatly appreciated.

  • How can I load style resources from a dynamically loaded Silverlight application (XAP)?

    - by Tom
    I've followed Tim Heuer's video for dynamically loading other XAP's (into a 'master' Silverlight application), as well as some other links to tweak the loading of resources and am stuck on the particular issue of loading style resources from within the dynamically loaded XAP (i.e. the contents of Assets\Styles.xaml). When I run the master/hosting applcation, it successfully streams the dynamic XAP and I can read the deployment info etc. and load the assembly parts. However, when I actuall try to create an instance of a form from the Dynamic XAP, it fails with Cannot find a Resource with the Name/Key LayoutRootGridStyle which is in it's Assets\Styles.xaml file (it works if I run it directly so I know it's OK). For some reason these don't show up as application resources - not sure if I've totally got the wrong end of the stick, or am just missing something? Code snippet below (apologies it's a bit messy - just trying to get it working first) ... '' # Here's the code that reads the dynamic XAP from the web server ... '' #... wCli = New WebClient AddHandler wCli.OpenReadCompleted, AddressOf OpenXAPCompleted wCli.OpenReadAsync(New Uri("MyTest.xap", UriKind.Relative)) '' #...

  • CGContextDrawPDFPage doesn't seem to persist in CGContext

    - by erichf
    I am trying to access the pixels of a CGContext written to with a PDF, but the bitmap buffer doesn't seem to update. Any help would be appreciated: //Get the reference to our current page pageRef = CGPDFDocumentGetPage(docRef, iCurrentPage); //Start with a media crop, but see if we can shrink to smaller crop CGRect pdfRect1 = CGRectIntegral(CGPDFPageGetBoxRect(pageRef, kCGPDFMediaBox)); CGRect r1 = CGRectIntegral(CGPDFPageGetBoxRect(pageRef, kCGPDFCropBox)); if (!CGRectIsEmpty(r1)) pdfRect1 = r1; int wide = pdfRect1.size.width + pdfRect1.origin.x; int high = pdfRect1.size.height + pdfRect1.origin.y; CGContextRef ctxBuffer = NULL; CGColorSpaceRef colorSpace; UInt8* bitmapData; int bitmapByteCount; int bitmapBytesPerRow; bitmapBytesPerRow = (wide * 4); bitmapByteCount = (bitmapBytesPerRow * high); colorSpace = CGColorSpaceCreateDeviceRGB(); bitmapData = malloc( bitmapByteCount ); if (bitmapData == NULL) { DebugLog (@"Memory not allocated!"); return; } ctxBuffer = CGBitmapContextCreate (bitmapData, wide, high, 8, // bits per component bitmapBytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); // if (ctxBuffer== NULL) { free (bitmapData); DebugLog (@"Context not created!"); return; } CGColorSpaceRelease( colorSpace ); //White out the current context CGContextSetRGBFillColor(ctxBuffer, 1.0, 1.0, 1.0, 1.0); CGContextFillRect(ctxBuffer, CGContextGetClipBoundingBox(ctxBuffer)); CGContextDrawPDFPage(ctxBuffer, pageRef); //!!!This displays just fine to the context passed in from - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx. That is, I can see the PDf page rendered, so we know ctxBuffer was created correctly //However, if I view bitmapData in memory, it only shows as 0xFF (or whatever fill color I use) CGImageRef img = CGBitmapContextCreateImage(ctxBuffer); CGContextDrawImage(ctx, tiledLayer.frame, img); void *data = CGBitmapContextGetData (ctx); for (int i = 0; i < wide; i++) { for (int j = 0; j < high; j++) { //All of the bytes show as 0xFF (or whatever fill color I test with)?! int byteIndex = (j * 4) + i * 4; UInt8 red = bitmapData[byteIndex]; UInt8 green = bitmapData[byteIndex + 1]; UInt8 blue = bitmapData[byteIndex + 2]; UInt8 alpha = m_PixelBuf[byteIndex + 3]; } } I have also tried using CGDataProviderCopyData(CGImageGetDataProvider(img)) & CFDataGetBytePtr, but the results are the same?

  • How can I use a custom TabItem control when databinding a TabControl in WPF?

    - by Russ
    I have a custom control that is derived from TabItem, and I want to databind that custom TabItem to a stock TabControl. I would rather avoid creating a new TabControl just for this rare case. This is what I have and I'm not having any luck getting the correct control to be loaded. In this case I want to use my ClosableTabItem control instead of the stock TabItem control. <TabControl x:Name="tabCases" IsSynchronizedWithCurrentItem="True" Controls:ClosableTabItem.TabClose="TabClosed" > <TabControl.ItemTemplate> <DataTemplate DataType="{x:Type Controls:ClosableTabItem}" > <TextBlock Text="{Binding Path=Id}" /> </DataTemplate> </TabControl.ItemTemplate> <TabControl.ContentTemplate> <DataTemplate DataType="{x:Type Entities:Case}"> <CallLog:CaseReadOnlyDisplay DataContext="{Binding}" /> </DataTemplate> </TabControl.ContentTemplate> </TabControl> EDIT: This is what I ended up with, rather than trying to bind a custom control.

  • ASP.NET MVC ViewModel Pattern

    - by Omu
    EDIT: I made something much better to fill and read data from a view using ViewModels, called it ValueInjecter. http://valueinjecter.codeplex.com/documentation using the ViewModel to store the mapping logic was not such a good idea because there was repetition and SRP violation, but now with the ValueInjecter I have clean ViewModels and dry mapping code I made a ViewModel pattern for editing stuff in asp.net mvc this pattern is usefull when you have to make a form for editing an entity and you have to put on the form some dropdowns for the user to choose some values public class OrganisationViewModel { //paramterless constructor required, cuz we are gonna get an OrganisationViewModel object from the form in the post save method public OrganisationViewModel() : this(new Organisation()) {} public OrganisationViewModel(Organisation o) { Organisation = o; Country = new SelectList(LookupFacade.Country.GetAll(), "ID", "Description", CountryKey); } //that's the Type for whom i create the viewmodel public Organisation Organisation { get; set; } #region DropDowns //for each dropdown i have a int? Key that stores the selected value public IEnumerable<SelectListItem> Country { get; set; } public int? CountryKey { get { if (Organisation.Country != null) { return Organisation.Country.ID; } return null; } set { if (value.HasValue) { Organisation.Country = LookupFacade.Country.Get(value.Value); } } } #endregion } and that's how i use it public ViewResult Edit(int id) { var model = new OrganisationViewModel(organisationRepository.Get(id)); return View(model); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(OrganisationViewModel model) { organisationRepository.SaveOrUpdate(model.Organisation); return RedirectToAction("Index"); } and the markup <p> <label for="Name"> Name:</label> <%= Html.Hidden("Organisation.ID", Model.Organisation.ID)%> <%= Html.TextBox("Organisation.Name", Model.Organisation.Name)%> <%= Html.ValidationMessage("Organisation.Name", "*")%> </p> <p> ... <label for="CountryKey"> Country:</label> <%= Html.DropDownList("CountryKey", Model.Country, "please select") %> <%= Html.ValidationMessage("CountryKey", "*") %> </p> so tell me what you think about it

  • QueryInterface fails at casting inside COM-interface implementation

    - by brecht
    I am creating a tool in c# to retrieve messages of a CAN-network (network in a car) using an Dll written in C/C++. This dll is usable as a COM-interface. My c#-formclass implements one of these COM-interfaces. And other variables are instantiated using these COM-interfaces (everything works perfect). The problem: The interface my C#-form implements has 3 abstract functions. One of these functions is called -by the dll- and i need to implement it myself. In this function i wish to retrieve a property of a form-wide variable that is of a COM-type. The COM library is CANSUPPORTLib The form-wide variable: private CANSUPPORTLib.ICanIOEx devices = new CANSUPPORTLib.CanIO(); This variable is also form-wide and is retrieved via the devices-variable: canreceiver = (CANSUPPORTLib.IDirectCAN2)devices.get_DirectDispatch(receiverLogicalChannel); The function that is called by the dll and implemented in c# public void Message(double dTimeStamp) { Console.WriteLine("!!! message ontvangen !!!" + Environment.NewLine); try { CANSUPPORTLib.can_msg_tag message = new CANSUPPORTLib.can_msg_tag(); message = (CANSUPPORTLib.can_msg_tag) System.Runtime.InteropServices.Marshal.PtrToStructure(canreceiver.RawMessage, message.GetType()); for (int i = 0; i < message.data.Length; i++) { Console.WriteLine("byte " + i + ": " + message.data[i]); } } catch (Exception e) { Console.WriteLine(e.Message); } } The error rises at this line: message = (CANSUPPORTLib.can_msg_tag)System.Runtime.InteropServices.Marshal.PtrToStructure(canreceiver.RawMessage, message.GetType()); Error: Unable to cast COM object of type 'System.__ComObject' to interface type 'CANSUPPORTLib.IDirectCAN2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{33373EFC-DB42-48C4-A719-3730B7F228B5}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Notes: It is possible to have a timer-clock that checks every 100ms for the message i need. The message is then retrieved in the exact same way as i do now. This timer is started when the form starts. The checking is only done when Message(double) has put a variable to true (a message arrived). When the timer-clock is started in the Message function, i have the same error as above Starting another thread when the form starts, is also not possible. Is there someone with experience with COM-interop ? When this timer

  • Python - calculate multinomial probability density functions on large dataset?

    - by Seafoid
    Hi, I originally intended to use MATLAB to tackle this problem but the inbuilt functions has limitations that do not suit my goal. The same limitation occurs in NumPy. I have two tab-delimited files. The first is a file showing amino acid residue, frequency and count for an in-house database of protein structures, i.e. A 0.25 1 S 0.25 1 T 0.25 1 P 0.25 1 The second file consists of quadruplets of amino acids and the number of times they occur, i.e. ASTP 1 Note, there are 8,000 such quadruplets. Based on the background frequency of occurence of each amino acid and the count of quadruplets, I aim to calculate the multinomial probability density function for each quadruplet and subsequently use it as the expected value in a maximum likelihood calculation. The multinomial distribution is as follows: f(x|n, p) = n!/(x1!*x2!*...*xk!)*((p1^x1)*(p2^x2)*...*(pk^xk)) where x is the number of each of k outcomes in n trials with fixed probabilities p. n is 4 four in all cases in my calculation. I have created three functions to calculate this distribution. # functions for multinomial distribution def expected_quadruplets(x, y): expected = x*y return expected # calculates the probabilities of occurence raised to the number of occurrences def prod_prob(p1, a, p2, b, p3, c, p4, d): prob_prod = (pow(p1, a))*(pow(p2, b))*(pow(p3, c))*(pow(p4, d)) return prob_prod # factorial() and multinomial_coefficient() work in tandem to calculate C, the multinomial coefficient def factorial(n): if n <= 1: return 1 return n*factorial(n-1) def multinomial_coefficient(a, b, c, d): n = 24.0 multi_coeff = (n/(factorial(a) * factorial(b) * factorial(c) * factorial(d))) return multi_coeff The problem is how best to structure the data in order to tackle the calculation most efficiently, in a manner that I can read (you guys write some cryptic code :-)) and that will not create an overflow or runtime error. To data my data is represented as nested lists. amino_acids = [['A', '0.25', '1'], ['S', '0.25', '1'], ['T', '0.25', '1'], ['P', '0.25', '1']] quadruplets = [['ASTP', '1']] I initially intended calling these functions within a nested for loop but this resulted in runtime errors or overfloe errors. I know that I can reset the recursion limit but I would rather do this more elegantly. I had the following: for i in quadruplets: quad = i[0].split(' ') for j in amino_acids: for k in quadruplets: for v in k: if j[0] == v: multinomial_coefficient(int(j[2]), int(j[2]), int(j[2]), int(j[2])) I haven'te really gotten to how to incorporate the other functions yet. I think that my current nested list arrangement is sub optimal. I wish to compare the each letter within the string 'ASTP' with the first component of each sub list in amino_acids. Where a match exists, I wish to pass the appropriate numeric values to the functions using indices. Is their a better way? Can I append the appropriate numbers for each amino acid and quadruplet to a temporary data structure within a loop, pass this to the functions and clear it for the next iteration? Thanks, S :-)

  • Opinions on sensor / reading / alert database design

    - by Mark
    I've asked a few questions lately regarding database design, probably too many ;-) However I beleive I'm slowly getting to the heart of the matter with my design and am slowly boiling it down. I'm still wrestling with a couple of decisions regarding how "alerts" are stored in the database. In this system, an alert is an entity that must be acknowledged, acted upon, etc. Initially I related readings to alerts like this (very cut down) : - [Location] LocationId [Sensor] SensorId LocationId UpperLimitValue LowerLimitValue [SensorReading] SensorReadingId Value Status Timestamp [SensorAlert] SensorAlertId [SensorAlertReading] SensorAlertId SensorReadingId The last table is associating readings with the alert, because it is the reading that dictate that the sensor is in alert or not. The problem with this design is that it allows readings from many sensors to be associated with a single alert - whereas each alert is for a single sensor only and should only have readings for that sensor associated with it (should I be bothered that the DB allows this though?). I thought to simplify things, why even bother with the SensorAlertReading table? Instead I could do this: [Location] LocationId [Sensor] SensorId LocationId [SensorReading] SensorReadingId SensorId Value Status Timestamp [SensorAlert] SensorAlertId SensorId Timestamp [SensorAlertEnd] SensorAlertId Timestamp Basically I'm not associating readings with the alert now - instead I just know that an alert was active between a start and end time for a particular sensor, and if I want to look up the readings for that alert I can do. Obviously the downside is I no longer have any constraint stopping me deleting readings that occurred during the alert, but I'm not sure that the constraint is neccessary. Now looking in from the outside as a developer / DBA, would that make you want to be sick or does it seem reasonable? Is there perhaps another way of doing this that I may be missing? Thanks. EDIT: Here's another idea - it works in a different way. It stores each sensor state change, going from normal to alert in a table, and then readings are simply associated with a particular state. This seems to solve all the problems - what d'ya think? (the only thing I'm not sure about is calling the table "SensorState", I can't help think there's a better name (maybe SensorReadingGroup?) : - [Location] LocationId [Sensor] SensorId LocationId [SensorState] SensorStateId SensorId Timestamp Status IsInAlert [SensorReading] SensorReadingId SensorStateId Value Timestamp There must be an elegant solution to this!

  • Semi-complex aggregate select statement confusion

    - by Ian Henry
    Alright, this problem is a little complicated, so bear with me. I have a table full of data. One of the table columns is an EntryDate. There can be multiple entries per day. However, I want to select all rows that are the latest entry on their respective days, and I want to select all the columns of said table. One of the columns is a unique identifier column, but it is not the primary key (I have no idea why it's there; this is a pretty old system). For purposes of demonstration, say the table looks like this: create table ExampleTable ( ID int identity(1,1) not null, PersonID int not null, StoreID int not null, Data1 int not null, Data2 int not null, EntryDate datetime not null ) The primary key is on PersonID and StoreID, which logically defines uniqueness. Now, like I said, I want to select all the rows that are the latest entries on that particular day (for each Person-Store combination). This is pretty easy: --Figure 1 select PersonID, StoreID, max(EntryDate) from ExampleTable group by PersonID, StoreID, dbo.dayof(EntryDate) Where dbo.dayof() is a simple function that strips the time component from a datetime. However, doing this loses the rest of the columns! I can't simply include the other columns, because then I'd have to group by them, which would produce the wrong results (especially since ID is unique). I have found a dirty hack that will do what I want, but there must be a better way -- here's my current solution: select cast(null as int) as ID, PersonID, StoreID, cast(null as int) as Data1, cast(null as int) as Data2, max(EntryDate) as EntryDate into #StagingTable from ExampleTable group by PersonID, StoreID, dbo.dayof(EntryDate) update Target set ID = Source.ID, Data1 = Source.Data1, Data2 = Source.Data2, from #StagingTable as Target inner join ExampleTable as Source on Source.PersonID = Target.PersonID and Source.StoreID = Target.StoreID and Source.EntryDate = Target.EntryDate This gets me the correct data in #StagingTable but, well, look at it! Creating a table with null values, then doing an update to get the values back -- surely there's a better way to do this? A single statement that will get me all the values the first time? It is my belief that the correct join on that original select (Figure 1) would do the trick, like a self-join or something... but how do you do that with the group by clause? I cannot find the right syntax to make the query execute. I am pretty new with SQL, so it's likely that I'm missing something obvious. Any suggestions? (Working in T-SQL, if it makes any difference)

  • Another design-related C++ question

    - by Kotti
    Hi! I am trying to find some optimal solutions in C++ coding patterns, and this is one of my game engine - related questions. Take a look at the game object declaration (I removed almost everything, that has no connection with the question). // Abstract representation of a game object class Object : public Entity, IRenderable, ISerializable { // Object parameters // Other not really important stuff public: // @note Rendering template will never change while // the object 'lives' Object(RenderTemplate& render_template, /* params */) : /*...*/ { } private: // Object rendering template RenderTemplate render_template; public: /** * Default object render method * Draws rendering template data at (X, Y) with (Width, Height) dimensions * * @note If no appropriate rendering method overload is specified * for any derived class, this method is called * * @param Backend & b * @return void * @see */ virtual void Render(Backend& backend) const { // Render sprite from object's // rendering template structure backend.RenderFromTemplate( render_template, x, y, width, height ); } }; Here is also the IRenderable interface declaration: // Objects that can be rendered interface IRenderable { /** * Abstract method to render current object * * @param Backend & b * @return void * @see */ virtual void Render(Backend& b) const = 0; } and a sample of a real object that is derived from Object (with severe simplifications :) // Ball object class Ball : public Object { // Ball params public: virtual void Render(Backend& b) const { b.RenderEllipse(/*params*/); } }; What I wanted to get is the ability to have some sort of standard function, that would draw sprite for an object (this is Object::Render) if there is no appropriate overload. So, one can have objects without Render(...) method, and if you try to render them, this default sprite-rendering stuff is invoked. And, one can have specialized objects, that define their own way of being rendered. I think, this way of doing things is quite good, but what I can't figure out - is there any way to split the objects' "normal" methods (like Resize(...) or Rotate(...)) implementation from their rendering implementation? Because if everything is done the way described earlier, a common .cpp file, that implements any type of object would generally mix the Resize(...), etc methods implementation and this virtual Render(...) method and this seems to be a mess. I actually want to have rendering procedures for the objects in one place and their "logic implementation" - in another. Is there a way this can be done (maybe alternative pattern or trick or hint) or this is where all this polymorphic and virtual stuff sucks in terms of code placement?

  • Fluent NHibernate - How to map a non nullable foreign key that exists in two joined tables

    - by vakman
    I'm mapping a set of membership classes for my application using Fluent NHibernate. I'm mapping the classes to the asp.net membership database structure. The database schema relevant to the problem looks like this: ASPNET_USERS UserId PK ApplicationId FK NOT NULL other user columns ... ASPNET_MEMBERSHIP UserId PK,FK ApplicationID FK NOT NULL other membership columns... There is a one to one relationship between these two tables. I'm attempting to join the two tables together and map data from both tables to a single 'User' entity which looks like this: public class User { public virtual Guid Id { get; set; } public virtual Guid ApplicationId { get; set; } // other properties to be mapped from aspnetuser/membership tables ... My mapping file is as follows: public class UserMap : ClassMap<User> { public UserMap() { Table("aspnet_Users"); Id(user => user.Id).Column("UserId").GeneratedBy.GuidComb(); Map(user => user.ApplicationId); // other user mappings Join("aspnet_Membership", join => { join.KeyColumn("UserId"); join.Map(user => user.ApplicationId); // Map other things from membership to 'User' class } } } If I try to run with the code above I get a FluentConfiguration exception Tried to add property 'ApplicationId' when already added. If I remove the line "Map(user = user.ApplicationId);" or change it to "Map(user = user.ApplicationId).Not.Update().Not.Insert();" then the application runs but I get the following exception when trying to insert a new user: Cannot insert the value NULL into column 'ApplicationId', table 'ASPNETUsers_Dev.dbo.aspnet_Users'; column does not allow nulls. INSERT fails. The statement has been terminated. And if I leave the .Map(user = user.ApplicationId) as it originally was and make either of those changes to the join.Map(user = user.ApplicationId) then I get the same exception above except of course the exception is related to an insert into the aspnet_Membership table So... how do I do this kind of mapping assuming I can't change my database schema?

  • Stretching width correctly to 100% of an inline-block element in IE6 and IE7

    I have the following markup, where I am attempting to get the right hand side of the second table to align with the right hand side of the heading above it.

  • Delphi native Web Service applications not working. IIS 7 seems to be stripping the pathinfo

    - by Cary Jensen
    I've run into an interesting problem that I never encountered with XP or IIS 6. Basically, I can't get a native Delphi (WebBroker) Web service server to work with a native Web service client in Windows 7 64-bit. Here's the most basic breakdown. If I create a new Web service application in Delphi 2010 (or any version, back to Delphi 7), and access it using IE 8, I can see the HTML that the WSDLHTMLPublish component creates, but I can never get to the SOAP. In the same way, the WSDL Importer cannot get to the SOAP either. (I have IIS 7 configured to use a 32-bit application pool, and I have created a working Script Map to the Handler Mappings. In short, the 32-bit ISAPI Web service is running). For example, I have a simple Web service server named TestService (created using the default sample interface generated when you create a new Web service server). I installed it in a virtual directory named scripts. If I enter http://localhost/scripts/TestService.dll/wsdl, IIS 7 displays the page http://localhost/scripts/TestService.dll. If I put my mouse over the WSDL link for the ITestService, I see http://localhost/scripts/TestService.dll/wsdl/ITestService in the status bar. However, when I click this link, the address bar shows http://localhost/scripts/TestService.dll/wsdl/ITestService, but I see only the HTML from http://localhost/scripts/TestService.dll. There seems no way to get to the SOAP definition. IIS 7 seems to be ignoring everything after the script name (it is ignoring the pathinfo). Additional evidence that IIS7 is stripping off the pathinfo is that if I pause my mouse over the ITestService link, the statusbar shows http://localhost/scripts/TestService.dll?intf=ITestService. Clicking that link takes me to another HTML page, the one associated with http://localhost/scripts/TestService.dll?intf=ITestService. However, any link that includes a pathinfo following the script name, takes me simply to http://localhost/scripts/TestService.dll. I have tested this in Delphi 7, Delphi 2010, and Delphi XE, with the same results. I am guessing that IIS7 is stripping off the pathinfo, since even the WSDL Importer cannot get to the SOAP definition. Tried creating a new Web service using the CGI option, and got the same result. Have any idea what is going on? Added: Bob Swart reports he has had no problems under Windows 7 32-bit. Downloading the 32-bit OS and will try that (in a new VM).

  • trying to build Boost MPI, but the lib files are not created. What's going on?

    - by unknownthreat
    I am trying to run a program with Boost MPI, but the thing is I don't have the .lib. So I try to create one by following the instruction at http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.config The instruction says "For many users using LAM/MPI, MPICH, or OpenMPI, configuration is almost automatic", I got myself OpenMPI in C:\, but I didn't do anything more with it. Do we need to do anything with it? Beside that, another statement from the instruction: "If you don't already have a file user-config.jam in your home directory, copy tools/build/v2/user-config.jam there." Well, I simply do what it says. I got myself "user-config.jam" in C:\boost_1_43_0 along with "using mpi ;" into the file. Next, this is what I've done: bjam --with-mpi C:\boost_1_43_0>bjam --with-mpi WARNING: No python installation configured and autoconfiguration failed. See http://www.boost.org/libs/python/doc/building.html for configuration instructions or pass --without-python to suppress this message and silently skip all Boost.Python targets Building the Boost C++ Libraries. warning: skipping optional Message Passing Interface (MPI) library. note: to enable MPI support, add "using mpi ;" to user-config.jam. note: to suppress this message, pass "--without-mpi" to bjam. note: otherwise, you can safely ignore this message. warning: Unable to construct ./stage-unversioned warning: Unable to construct ./stage-unversioned Component configuration: - date_time : not building - filesystem : not building - graph : not building - graph_parallel : not building - iostreams : not building - math : not building - mpi : building - program_options : not building - python : not building - random : not building - regex : not building - serialization : not building - signals : not building - system : not building - test : not building - thread : not building - wave : not building ...found 1 target... The Boost C++ Libraries were successfully built! The following directory should be added to compiler include paths: C:\boost_1_43_0 The following directory should be added to linker library paths: C:\boost_1_43_0\stage\lib C:\boost_1_43_0> I see that there are many libs in C:\boost_1_43_0\stage\lib, but I see no trace of libboost_mpi-vc100-mt-1_43.lib or libboost_mpi-vc100-mt-gd-1_43.lib at all. These are the libraries required for linking in mpi applications. What could possibly gone wrong when libraries are not being built?
