• Embedded BI for ASP.NET

  - by Michael Shimmins

  Can anyone recommend a decent business intelligence & reporting application that can be integrated into an OEM application? Primary requirements are: Administrators can define cubes/dimensions etc (or we - the OEM - can predefine some) Report designers can easily inspect data by visually selecting dimensions, filters etc in an adhoc way that is quickly output with little upfront investment Report designers can design a report based on dimensions/filters and save their definition to be run as required Report viewers can view the reports defined by the report designers All of this plus in .NET that can be branded/integrated into our existing web application's look and feel. Permissions need to work off our user/groups system. I've found a few that look good, but they are all in Java and I don't want to ask our clients to install ASP.NET for the app, and then Java, tomcat etc just for reporting. Thanks

• Performance of std::pow - cache misses???

  - by Eamon Nerbonne

  I've been trying to optimize a numeric program of mine, and have run into something of a mystery. I'm looping over code that performs thousands of floating point operations, and just 1 call to pow nevertheless, that call takes 5% of the time... That's not necessarily a critical issue, but it is odd, so I'd like to understand what's happening. When I profiled for cache misses, VS.NET 2010RC's profiler reports that virtually all cache misses are occurring in std::pow... so... what's up with that? Is there a faster alternative? I tried powf, but that's only slightly faster; it's still responsible for an abnormal number of cache misses. Why would a basic function like pow cause cache-misses?

• Weird Excel Formatting

  - by Gage

  Recently a new co-op was hired at our company and has been tasked to run a report. The report queries the database and returns a resultset and from there procedes to create the spreadsheets. Depending on the number of days selected a different number of reports are generated but I do not believe that is relavent to the question. Basically it runs the reports and loops through the resultset but at some point continues to loop through until tow 65536 at which it stops. For Example if the resultset contained 74 records then the first 74 rows would appear normally (formatted yellow) while everything after that would also be formatted yellow although it should be left alone. I am inheriting this code as I to am a new co-op. Apparently this only happens when a "change of guards" happens (New co-op has to run the report).` DoCmd.SetWarnings False DoCmd.OpenQuery ("DailySummaryQueryMain") strSQL = "SELECT * FROM DailySummaryMain" Set rs = CurrentDb.OpenRecordset(strSQL) DoCmd.Echo True, "Running first Report" If Not rs.EOF Then rs.MoveFirst Do While Not rs.EOF And Not rs.BOF xlapp.Range("A" & i).Value = rs.Fields(0).Value xlapp.Range("B" & i).Value = rs.Fields(1).Value xlapp.Range("C" & i).Value = rs.Fields(2).Value Set rs2 = CurrentDb.OpenRecordset("SELECT dbo_StatusType.StatusTypeID, dbo_StatusType.Name FROM dbo_StatusType WHERE (((dbo_StatusType.StatusTypeID)=" & rs.Fields(3) & "))") rs2.MoveFirst xlapp.Range("D" & i).Value = rs2.Fields(1).Value xlapp.Range("E" & i).Value = rs.Fields(4).Value xlapp.Range("F" & i).Value = rs.Fields(5).Value xlapp.Range("G" & i).Value = rs.Fields(6).Value 'count number of outages that start and end on same day If Format(xlapp.Range("F" & i).Value, "mm/dd/yyyy") = Format(xlapp.Range("G" & i).Value, "mm/dd/yyyy") Then dayCount = dayCount + 1 End If xlapp.Range("H" & i).Value = rs.Fields(7).Value xlapp.Range("I" & i).Value = rs.Fields(8).Value xlapp.Range("J" & i).Value = rs.Fields(9).Value xlapp.Range("K" & i).Value = rs.Fields(10).Value xlapp.Range("L" & i).Value = rs.Fields(11).Value xlapp.Range("M" & i).Value = rs.Fields(12).Value xlapp.Range("N" & i).Value = rs.Fields(13).Value 'highlite recently modified rows If rs.Fields(14).Value = "Yes" Then xlapp.Range("A" & i & ":N" & i).Select With xlapp.Selection.Interior .ColorIndex = 36 .Pattern = xlSolid End With End If 'break apart by sector If CInt(rs.Fields(2).Value) = 1 Then row = row1 ElseIf CInt(rs.Fields(2).Value) = 2 Then row = row2 ElseIf CInt(rs.Fields(2).Value) = 3 Then row = row3 Else row = row4 End If xlapp.Worksheets(CInt(rs.Fields(2).Value) + 1).Activate xlapp.Range("A" & row).Value = rs.Fields(0).Value xlapp.Range("B" & row).Value = rs.Fields(1).Value xlapp.Range("C" & row).Value = rs.Fields(13).Value xlapp.Range("D" & row).Value = rs.Fields(4).Value xlapp.Range("E" & row).Value = rs.Fields(5).Value xlapp.Range("F" & row).Value = rs.Fields(6).Value xlapp.Range("G" & row).Value = rs.Fields(7).Value xlapp.Range("H" & row).Value = rs.Fields(8).Value xlapp.Range("I" & row).Value = rs.Fields(9).Value xlapp.Range("J" & row).Value = rs.Fields(10).Value xlapp.Range("K" & row).Value = "" xlapp.Range("L" & row).Value = rs.Fields(11).Value xlapp.Range("M" & row).Value = rs.Fields(13).Value If CInt(rs.Fields(2).Value) = 1 Then row1 = row1 + 1 ElseIf CInt(rs.Fields(2).Value) = 2 Then row2 = row2 + 1 ElseIf CInt(rs.Fields(2).Value) = 3 Then row3 = row3 + 1 Else row4 = row4 + 1 End If 'activate main summary sheet for next outage xlapp.Worksheets(1).Activate i = i + 1 rs.MoveNext Loop` Also I should note that this is all happening within an access database which has its tables linked from SQL. The query is extremely slow to run from which I believe is the use of views but thats neither here nor there. All you have to know is attempting to debug takes an enormous amount of time due to having to wait for the recordset to return. My guess is that its not checking to see if the resultset is empty correctly. Is there a way I could check to see if theres a value is rs.Fields(0) and base it off that maybe? That is the ID column and there should always be a value. I am wondering why rs.EOF isn't catching this though.

• Flot Pie Chart using Ajax, Php and MySql

  - by Neriza Almirol

  Good Day! Can you help me? I have a problem getting values from database. I want to control the legend. I've been googling the best approach for the pie chart, but still looking for the best answer for my problem. It's easy to query the data from the database, but I want to show it using the flot pie chart and I need it for statistic reports. From database, I need to get the percentage of Female and Male followers and separate it according to age groups. The data (dateOfbirth) is available from our database using facebook integration. Can you give me an example using Ajax, Php and MySql? Thank you! :) $.plot($("#graph_3"), graphData, { series: { pie: { show: true } }, grid: { hoverable: true, clickable: true } }); $("#graph_3").bind("plothover", pieHover); $("#graph_3").bind("plotclick", pieClick);

• Most user-friendly issue tracker?

  - by Kugel

  Sorry if this has been asked before, couldn't find anything specific. I'm looking for the most user-friendly issue tracker. Currently I'm using Trac. I'm looking for these 2 features: Very easy to create new ticket Email to ticket conversion (with attachements). The customers should be glad to use it (not avoid it like Trac). More often than not I get e-mails as bug reports and putting them into Trac wastes my time. I would really love to just hit forward and the ticket would appear in the issue tracker.

• Anyone successfully using Commission Junction API ?

  - by Mauricio Scheffer

  Is anyone successfully using the CJ web services? I just keep getting java.lang.NullPointerExceptions even though my app is .net (clearly their errors). CJ support doesn't even know what a web service is. I googled and found many people getting this or other errors. Question is: is it a temporary problem or am I doomed to parse manually downloaded reports for eternity? The specific API I'm trying to use is the daily publisher commission service. Here is the WSDL. Links: CJ web services home API Reference

• Site Actions menu in SharePoint is WSS-like, whereas I have installed MOSS

  - by Graeme

  I had WSS installed on my VM and then uninstalled in order to install MOSS Enterprise I can see a lot of the MOSS stuff in the Central Administration pages but when I create a new web application and site collection, my Site Actions dropdown is showing the WSS version, i.e. Create, Edit Page and Site Settings as opposed to the MOSS menu which has View All Site Content, View Reports, Manage Content and Structure etc. I just tried deleting my web app and creating it all again but it's come back with the same thing again. Is somewhere remembering that I used to have WSS installed? (yes I know MOSS is built on top of WSS but you know what I mean!)

• Switching VS2010 to use Windows 7.1 SDK

  - by freefallr

  I've used VS2008 on my development machine for some years now, with windows SDK v7.1. I've installed VS2010, and it's using the Windows SDK v7.0a, but I need it to use the Windows 7.1 SDK (which I had installed prior to installing VS2010). When I run the Windows SDK 7.1 configuration tool, to switch the Windows SDK in use, the tool updates for VS2008, but not for VS2010. The message it reports is: "The Windows SDK Configuration Tool has successfully set Windows SDK version v7.1 as the current version for Visual Studio 2008" The configuration tool is installed with the Windows 7.1 SDK and is found here: "C:\Program Files\Microsoft SDKs\Windows\v7.1\Setup\WindowsSdkVer.exe" VS2010 continues to use WSDK 7.0a, which extremely frustrating, as I need to do DirectShow development (so I need to build the baseclasses, which aren't released with 7.0a release of WSDK). Would I be correct in assuming that it's not updating VS2010 settings because VS2010 wasn't installed at the time that I installed Windows 7.1 SDK? Can I fix this manually, or should I uninstall Windows 7.1 SDK, then reinstall it? Any other suggestions / workarounds for this?

• How to create generic class which takes 3 types.

  - by scope-creep

  I'm trying to make a generic class that takes 3 types, either a simple string, IList or a IList. public class OntologyStore { } public sealed class jim<T> where T:new() { IList<string> X = null; IList<OntologyStore> X1 = null; public bob() { if (typeof(T) == typeof(String)) { X = new List<string>(); } if (typeof(T) == typeof(OntologyStore)) { X1 = new List<OntologyStore>(); } } } I can easily create, which you would expect to work, jim<OntologyStore> x1=new jim<jim<OntologyStore>() as you would expect, but when I put in jim<string> x2=new jim<string>() the compiler reports the string is non abtract type, which you would expect. Is it possible to create a generic class, which can instantiate as a class which holds string, or a IList or an IList?

• Microsoft.Office.Interop.MSProject - why are my files always locked (by me!) when I try to open them

  - by Anders Juul

  Hi all, I'm trying to use Interop to manipulate MS Project 2003 (MPP) files. My problem is that MS Project reports that the files is already opened by another user (me!) and that I can open it only as read-only. Obviously, I've tried to restart studio, then windows (xp) but with no effect. The file attribute for Readonly is cleared on the file. Any suggestions for what I might try?! Thanks, Anders Imports Microsoft.Office.Interop.MSProject ... Dim app As ApplicationClass = New ApplicationClass() app.Visible = False Dim success As Boolean = app.FileOpen(fullPath, False)

• How to configure iReports to use grails domain class ?

  - by fabien-barbier

  I'm using JasperGrails plugins (http://www.grails.org/Jasper+Plugin) to generate reports. When I configure iReports dataSource with Database JDBC connection everything works well. But how to configure iReports with grails and Jasper plugin ? I try to configure my dataSource by selecting "JavaBeans set data source", but I have this error message : ClassNotFoundError ! (I try to add my domain in classpath by pointing to my IDEA project folder, but I have always same message). What is the best way to configure iReports with grails/groovy ?

• Using the sharepoint stsadm import command fails when list exists

  - by 78lro

  When using the stsadm -o import command in sharepoint I am getting an error relating to a list already existing, the import then seems to fail. Should it not handle this scenario of a list already existing on the destination server? I then used the UI to delete the existing list and ran the import again. It then seemed to fail at the same point saying the list exists. In the UI the list appears but when I click it, it reports that the list does not exist - almost as if it's stuck in a half created state, unable to be deleted or created by the import. Any suggestions greatly appreciated.

• DirectSound affects system volume on WinXP

  - by Anton

  Hello guys, I'm currently developing an audio engine that is used in voice network chat software. Everything is working fine - capture/playback/mixing channels. The problem is in using it under Windows XP. I've been getting user reports with information that their global system volume is set to zero after launching the application. I'm assuming that happens because of WaveOut/DSound conflict. How can I force DSound not to affect system volume? Playback device is initialized: DirectSoundCreate8(&GUID, &pAudio, NULL); and: pAudio-SetCooperativeLevel(parentWnd, DSSCL_PRIORITY); I'm currently not able to debug the application, cause I'm using Vista and everything is OK. Hope you can help me with this issue! Thanks a Lot! Regards, Anton.

• How to hook Pivotal Tracker to Redmine?

  - by cloneofsnake

  Our company is currently using Redmine, it's great for general tasks / troubleshooting (operation) but for development, I would like to adopt a more agile tool... and I found it in pivotaltracker. I googled but couldn't find any info., so that gave me a good excuse to try StackOverflow. Has anyone done it? I'm thinking of using PivotalTracker as the main tool, and all activities will be posted back to redmine for archiving and reporting. (Redmine isn't particularly strong at that either, but it does have a budget plugin and I can query the database directly for my custom reports.) Thanks.

• windbg/cdb hangs when bp hit

  - by aaron

  I have a problem where cdb or windbg hangs frequently, but not all the time, when I'm debugging with it and I attach to a specific application on my machine. I found this article: http://www.nynaeve.net/?p=164 which talks about a symbol loading race condition being the problem, but I can force load the symbols, actually have a breakpoint in-app work, and still have it hang elsewhere. Here is the stack from cdb itself when I attach to it with another debugger: ntdll!NtReadFile kernel32!ReadFile cdb!ReadNonConLine cdb!ConIn cdb!MainLoop cdb!main !analyze reports that APPLICATION_HANG_BusyHang is the problem bucket, and 'ReadNonConLine' is the offending function. as far as the stack goes: ffffffff`fffffffe 00000000`00000000 00000001`3f641498 00000000`0014ea50 : kernel32!ReadFile+0x86 00000000`000002a4 00000000`0014ebb0 00000000`00001000 00000000`00000000 : cdb!ReadNonConLine+0x6d ReadNonConLine has the string "g" at 0014ebb0 passed as a param, which may be part of the command I had at the hanging breakpoint (it was something like bp foo "dt a; g") ReadFile takes a handle as its first parameter. I'm surprised by the value -2, though, that doesn't look valid. Any help is appreciated. Thanks! Aaron

• JQuery: Problem in getting element's width in Chrome

  - by Sarfraz

  Hello, Suppose I have this image: <img src="images/01.jpg" border="0" rel="shadow" /> Then with JQuery, I get its width using: $('[rel="shadow"]').width(); Firefox and IE report correct dimensions of the image eg 140px while Chrome reports 0. How to solve this problem? Note: I don't want to set explicit width for images eg: <img src="images/01.jpg" border="0" rel="shadow" width="140" /> So, how to get width in cross-browser way which is not defined in width attribute of elements?

• MTU mismatch between GetIfEntry and netsh

  - by ChrisJ

  I'm working on pseudo-transport layer software that runs over UDP, providing reliable connection-oriented transmission, as an alternative to TCP. In order to maximize network efficiency, we query the MTU of the "best" network adapter upon initialization. MIB_IFROW row = {0}; row.dwIndex = dwBestIfIndex; dwRes = GetIfEntry(&row); Searching online I found that you can use the following netsh commands to query for this same value, from a command prompt (not a C++ API) netsh interface ipv4 show interfaces netsh interface ipv4 show subinterfaces The troubling issue is that while row.dwMtu may be set to 1500, snooping the network traffic on the sending laptop shows that our packets are fragmented into 1300 byte packets. netsh also reports that the MTU is 1300. Clearly the value reported by netsh command is the actual used values. Anyone know what API I can call to get the same values as netsh?

• transaction log shipping sql server 2005 to 2008

  - by Andrew Jahn

  I have a reporting setup with SSRS on our sql server 2005 database. Because sql server 2008 is not supported by the main program which populates our database we are stuck with 2005 on our prod database. Unfortunately when I run our weekly check reports the web interface constantly times out because the server cant do the conversion to PDF. I've read that sql server 2008's SSRS is ALOT better with memory management. I was wondering if I can do some kind transact log shipping subscription publication from 2005 to 2008? Am I chasing a dream here.

• iPhone app running in Instruments fails with unrecognized selector

  - by Mark Smith

  I have an app that appears to run without problems in normal use. The Clang Static Analyzer reports no problems either. When I try to run it in Instruments, it fails with an unrecognized selector exception. The offending line is a simple property setter of the form: self.bar = baz; To figure out what's going on, I added an NSLog() call immediately above it: NSLog(@"class = %@ responds = %d", [self class], [self respondsToSelector:@selector(setBar:)]); self.bar = baz; On the emulator (without Instruments) and on a device, this shows exactly what I'd expect: class = Foo responds = 1 When running under Instruments, I get: class = Foo responds = 0 I'm stumped as to what could cause this. Perhaps a different memory location is getting tromped on when it's in the Instruments environment? Can anyone suggest how I might debug this?

• Overload assignment operator for assigning sql::ResultSet to struct tm

  - by Luke Mcneice

  Are there exceptions for types which can't have thier assignment operator overloaded? Specifically, I'm wanting to overload the assignment operator of a struct tm (from time.h) so I can assign a sql::ResultSet to it. I already have the conversion logic: sscanf(sqlresult->getString("StoredAt").c_str(), "%d-%d-%d %d:%d:%d", &TempTimeStruct->tm_year, &TempTimeStruct->tm_mon, &TempTimeStruct->tm_mday, &TempTimeStruct->tm_hour, &TempTimeStruct->tm_min, &TempTimeStruct->tm_sec); I tried the overload with this: tm& tm::operator=(sql::ResultSet & results) { /*CODE*/ return *this; } However VS08 reports: error C2511: 'tm &tm::operator =(sql::ResultSet &)' : overloaded member function not found in 'tm'

• 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?

• SSRS 2008 Installation Guidelines/Best Practices?

  - by Brad Bowman

  I know I have seen recommendations for installing SSRS 2005 and it stated that you should separate SSRS from the DB Engine that hosts the data sources for your reports, that you should not install them on the same server. Is there any documentation for SSRS 2008 that provides guidelines/best practices for installation? I am assuming that the same holds true for SSRS 2008 as it did for SSRS 2005 but have not seen it specifically stated anywhere. We have a project that will utilize SSRS 2008 and there is a difference of opinion on where to install it, on it's own dedicated server or on the same SQL Server as the report data sources. If there is a link to any documentation that could be provided it would be gratefully appreciated, all I am finding besides what is in BOL refers to 2005. Thanks in advance!

• How can I connect to Android with ADB over TCP?

  - by martinjd

  I am attempting to debug an application on a Motorola Droid but I am having some difficulty connecting to the device via USB. My development server is a Windows 7 64bit VM running in HyperV and so I cannot connect directly via USB in the guest or from the host. I installed a couple of different USB over TCP solutions but the connection appears to have issues since the adb monitor reports "devicemonitor failed to start monitoring" repeatedly. I was wondering if there is a way to connect directly from the client on the development machine to the daemon on the device using the network instead of the usb connection or possibly other viable options?

• Export from HTML to PDF (C#)

  Hi, In our applications we make html documents as reports and exports. But now our customer wants a button that saves that document on their pc. The problem is that the document includes images. You can create a word document with the following code: private void WriteWordDoc(string docName) { Response.Buffer = true; Response.ContentType = "application/msword"; Response.AddHeader("content-disposition", String.Format("attachment;filename={0}.doc", docName.Replace(" ", "_"))); Response.Charset = "utf-8"; } But the problem is that the images are just links an thus not embedded in the word document. Therefore I'm looking for an alternative PDF seems to be a good alternative, does anyone know a good pdf writer for C#? One that has some good references and has been tested properly?
