• RDLC item width is dynamic and causing extra pages to be generated (image included)?

  - by Paul Mendoza

  I'm trying to format an RDLC report file in Visual Studio 2008 and I am having a formatting issue. I have a list at the bottom that contains a matrix that expands horizontally to the right. That pink box is just to visualize the problem I'm having. When the report is rendered the matrix expands and instead of filling the pink box with the matrix is pushes the space in the pink box to the right resulting in an extra page when printing the reports. One solution would be to shrink the pink box to be the size of the matrix which I've done. But then when the matrix grows the fields at the top of the report get pushed to the right by the same amount as the growth of the matrix. Can someone please let me know what they think the solution would be? Thank you!

• Drawing graphs in MS Excel somehow got complicated

  - by Ivan

  I want to draw several graphs and combine them into one figure. I will explain the problem in an example. Let's say that I want to draw two graphs with these points: Graph #1 (X and Y are defining a coordinate). X - Y _____ 1 - 5 2 - 5 5 - 7 9 - 10 Graph #2 X - Y _____ 6 - 8 8 - 12 9 - 7 12 - 8 15 - 11 21 - 11 What I do is that I create a chart and click on "Select Data". There I create two series and choose X and Y values. However, this doesn't work since it doesn't allow me to choose different X values for different graphs. Although I choose different for these two series, the second one is chosen for both. This is how it looks like in the end: Do you know how to fix this? I'm using Excel 2008 for Mac.

• How to control order of assignment for new identity column in mssql ?

  - by alpav

  I have a table with CreateDate datetime field default(getdate()) that does not have any identity column. I would like to add identity(1,1) field that would reflect same order of existing records as CreateDate field (order by would give same results). How can I do that ? I guess if I create clustered key on CreateDate field and then add identity column it will work (not sure if it's guaranteed), is there a good/better way ? I am interested in sql 2005, but I guess the answer will be the same for sql 2008, sql 2000.

• ASP.NET cached aspx page & IIS logs

  - by Vishal Seth

  Hi guys, Is there any way to find out if ASP.Net runtime has served a cached copy of ASPX page or actually went through the page life cycle? Here is my problem: I'm seeing many entries in my IIS log files that were served successfully (200 OK). I've a corresponding logging code (Log4Net API) in the Session_Start and Application_BeginRequest() events that is logging every request to my DB with more details. I'm not seeing any corresponding entries in my SQL DB for some cases that should have been created by Log4Net code. Are there any logs available to find out if a cached copy was served by .NET worker process? Moreover, if my logging code would throw an exception, won't that show up as 500 in IIS logs? The code is on Windows 2008 Server, IIS 7.

• Dynamic Database connection

  - by gsieranski

  I have multiple client databases that I need to hit on the fly and I am having trouble getting the code I have to work. At first I was just storing a connection string in a clinet object in the db, pulling it out based on logged-in user, and passing it to linq data context constructor. This works fine in my development enviorment but is failing on the Winhost server I am using. It is running SQL 2008. I am getting a "The current configuration system does not support user scoped settings." error. Any help or guidance on this issue is greatly appreciated. Greg

• Sequence Generators in T-SQL

  - by PaoloFCantoni

  We have an Oracle application that uses a standard pattern to populate surrogate keys. We have a series of extrinsic rows (that have specific values for the surrogate keys) and other rows that have intrinsic values. We use the following Oracle trigger snippet to determine what to do with the Surrogate key on insert: 'IF :NEW.SurrogateKey IS NULL THEN SELECT SurrogateKey_SEQ.NEXTVAL INTO :NEW.SurrogateKey FROM DUAL; END IF;' If the supplied surrogate key is null then get a value from the nominated sequence, else pass the supplied surrogate key through to the row. I can't seem to find an easy way to do this is T-SQL. There are all sorts of approaches, but none of which use the notion of a sequence generator like Oracle and other SQL-92 compliant DBs do. Anybody know of a really efficient way to do this in SQL Server T-SQL? BTW we're using SQL Server 2008 if that's any help. TIA, Paolo

• Console.Write Not Working In Win Forms App

  - by Steven

  I created a VB.NET Windows Forms Application in Visual Studio 2008. When I run my program from the command-line, I get no output (only the next prompt). What am I doing wrong? Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Debug.Write("Foo") Debug.Flush() Console.WriteLine("foo") Console.Beep(800, 100) 'confirm this function is called' Me.Close() End Sub EDIT: Can a program have a form and a console? EDIT2: Ho's answer works. However, the output appears on the next command-line prompt. Can a Winforms application tell the command-line to wait until it's finished instead of immediately returning?

• Search for Variable Usage In SSIS tasks

  - by yoni.s

  Hi all: As what seems to be some sort of penance for sins in a prior life, I have been tasked with maintaining some SSIS packages. (NO! NO BADMOUTHING SSIS!! BAD PROGRAMMMER! NO DOUGHNUT!). Anyhoo, I many of the packages have variables, defined in an outer container, which are used in multiple inner containers, in script tasks. What I want to do, is find out all the places in a package a variable being used; in other words, search for instances of variable usage in all tasks of a package. This would be a huge help, but I cannot for the life of me find out how this can be done in BIDS. (this is SSIS/BIDS 2008) Thanks for any help, YS

• How do I create queries to SQL Server tables via Visual Studio when no knowledge about SQL nor Linq?

  - by Kent S. Clarkson

  Let´s be frank, my knowledge regarding SQL language is very low. Nevertheless, my boss gave me the task to build a database application using the following tools: SQL Server and Visual Studio 2008; C#. I use the VS DataSet as a local mirror of the SQL Server. And let´s be frank again, my understanding of the VS Query builder is also very small, I´m finding it quite confusing, actually. So no help to find from Query builder. And my knowledge of Linq is even lower... Perhaps I should mention that the deadline for the project is "aggressively" set, so I have no chance to learn enough about these things during the project. And I´m a bit stupid too, which is no help when it comes to challenges like this (on other occations it might be quite useful though) With these permissions, what should I do (except for killing myself or retire) to be able to query my tables in a sufficient way?

• Checking COM Port Availability in C#

  - by Jim Fell

  Hello. My C# application populates a comboBox with the COM ports found on the system. I would like the mark the COM ports that are in use as such. I know that I can use try / catch blocks to attempt to open every COM port, but I was wondering if there is a more graceful way to do this. Perhaps using a WMI query? I am using Microsoft Visual C# 2008 Express Edition (.NET 2.0). Any thoughts or suggestions you may have would be appreciated. Thanks.

• Weird behaviour with vector::erase and std::remove_if with end range different from vector.end()

  - by Edison Gustavo Muenz

  Hi, I need to remove elements from the middle of a std::vector. So I tried: struct IsEven { bool operator()(int ele) { return ele % 2 == 0; } }; int elements[] = {1, 2, 3, 4, 5, 6}; std::vector<int> ints(elements, elements+6); std::vector<int>::iterator it = std::remove_if(ints.begin() + 2, ints.begin() + 4, IsEven()); ints.erase(it, ints.end()); After this I would expect that the ints vector have: [1, 2, 3, 5, 6]. In the debugger of Visual studio 2008, after the std::remove_if line, the elements of ints are modified, I'm guessing I'm into some sort of undefined behaviour here. So, how do I remove elements from a Range of a vector?

• Line numbering in Visual Studio

  - by Cyclone

  Why doesn't VS have any sort of line numbering? Is there any way to enable it, or a plugin for it? I know, the number of lines of code in a program doesn't matter, but sometimes it is nice to know how long a program is, or what line number something is for reference. I can't seem to find that as an option anywhere, to my surprise. Thanks for the help! This is Visual Studio 2010 Ultimate. (if you have read my older questions, I've been using 2008 Express until now.)

• .net app won't run. When compiling on dest machine (same sources) it does work. Why?

  - by reinier

  I have a service which needs to be deployed on a clients machine. The destination machine is 64bit. My dev machine is also 64 bit. The app is really simple, listens on a port and does some db things. It targets .net 3.5 When I deploy the Anycpu, the X64 or the X86 version, the thing won't install on the clients machine. I checked dependencywalker and it lists: devmgr.dll ieshims.dll wer.dll anyhow...I install visual studio 2008 on the clients machine... check out all the sources. I don't change a thing and compile. Copy the exe over to it's dest locations...and what do you know..it works. Dependencywalker still lists the same dependency problems. How can it be that the act of compiling it on this machine gives me a different exe?

• Error while installing Microsoft SQL Server 2005 on Windows 7

  - by Brian Roisentul

  I was trying to install Microsoft SQL Server 2005 on my Windows 7 pc. When I tried to install it, it tells me that I have a newer version installed on my pc. So, I checked that Microsoft Sharepoint 2010 installed some sql server 2008 tools for me. I decided to uninstall SharePoint 2010(which I wasn't using) and then tried to install MS SQL Server 2005 again. This threw me the following exception: Error 1603 installing microsoft sql server setup support files Searching on Google I found this article: http://support.microsoft.com/kb/916760 but it's not my case actually. Any help will be appreciated. I really need this to continue working.

• What to monitor on MSSQL Server

  - by user361434

  Hi all I have been asked to monitor MSSQL Server (2005 & 2008) and am wondering what are good metrics to look at? I can access WMI counters but am slightly lost as to how much depth is going to be useful. Currently I have on my list: user connections logins per second latch waits per second total latch wait time dead locks per second errors per second Log and data file sizes I am looking to be able to monitor values that will indicate a degradation of performance on the machine or a potential serious issue. To this end I am also wondering at what values some of these things would be considered normal vs problematic? As I reckon it would probably be a really good question to have answered for the general community I thought i'd court some of you DBA experts out there (I am certainly not one of them!) Apologies if a rather open ended question. Ry

• How to organize code using an optional assembly reference?

  - by apoorv020

  I am working on a project and want to optionally use an assembly if available. This assembly is only available on WS 2008 R2, and my ideal product whould be a common binary for both computers with and without the assembly. However, I'm primarily developing on a Windows 7 machine, where I cannot install the assembly. How can I organize my code so that I can (with minimum changes) build my code on a machine without the assembly and secondly, how do I ensure that I call the assembly functions only when it is present. (NOTE : The only use of the optional assembly is to instantiate a class in the library and repeatedly call a (single) function of the class, which returns a boolean. The assembly is fsrmlib, which exposes advanced file system management operations on WS08R2.) I'm currently thinking of writing a wrapper class, which will always return true if the assembly is not present. Is this the right way to go about doing this?

• How can I debug an application crash in Win7 after it's happened?

  - by parsley72

  I have a Visual Basic 6 application that I've recently changed to use a couple of C++ DLLs I've written in Visual Studio 2008. The application works fine on my PC, but when we install it on one of our test PCs it tends to crash during shutdown - we see the Win 7 message "Your application has failed" or whatever it is. I know Win 7 stores data that can be used to analyse the crash. I've got the source code and .PDB files from the build so I should be able to use that, but I can't figure out where Win 7 stores the data from the crash. The Event Viewer shows the crash but doesn't have any data and the directory C:\Windows\Minidump doesn't exist. Where do the crash files get put?

• Linq to SQL Azure genrating Error "Specified cast is not valid."

  - by Rabbi

  B"H I have an application that has been working for months using Linq to SQL connecting to a SQLExpress. I tried migrating it to SQL Azure. I copied the structure and data using the Sync Framework. I viewed the data in SQL Azure using SSMS 2008 R2 and it seams to be exactly what I have in my Sql Server. However when I try to use Linq to SQL against it I get an error "Specified cast is not valid." I seams to be happening any time I get child records. i.e. whenever I fill (the first time I access) an entity set. It seams to be happening after the data returns and when Linq tries to put it into the objects. remember, the application is working perfectly against sqlexpress, even when accessed across the internet or vpn.

• Using a WinForm as a Windows Installer Custom Action

  - by Serexx

  Hello - I am working on in installer project that needs to gather some info and act on it during the install (mainly online key retreival and registration). The Setup Project UserInterface templates seem inflexible and poorly documented so I am looking at opening a WinForm as a Custom Action. I know this is possible because I see reference to it in many places but this is my first Windows Installer experience and so far it is mired in googled contradictions, partial or outdated information and guesswork... erg.... Does anyone have (even a pointer to) a clear concise description of how one gets this done in a VS 2008 WinForm project... Many thanks for inputs

• Change .NET Framework version of application pool to 3.5?

  - by Sean Sexton

  I've installed .NET Framework 3.5 SP1 on web server (Server 2008 Enterprise), so running IIS 7.0. I want to change the version of .NET Framework used by an existing site. So I right-click on appropriate Application Pool and selected Edit Application Pool. The .NET Framework dropdown does not include an explicit entry for framework 3.5, but just 2.0.50727. Does anyone know off the top of their head--is this just because the version of the core RTL in 3.5 is still 2.0? Or do I need to do something additional to get IIS to see version 3.5? (Did try restarting IIS). Thanks!

• Large ResultSet on postgresql query

  - by tuler

  I'm running a query against a table in a postgresql database. The database is on a remote machine. The table has around 30 sub-tables using postgresql partitioning capability. The query will return a large result set, something around 1.8 million rows. In my code I use spring jdbc support, method JdbcTemplate.query, but my RowCallbackHandler is not being called. My best guess is that the postgresql jdbc driver (I use version 8.3-603.jdbc4) is accumulating the result in memory before calling my code. I thought the fetchSize configuration could control this, but I tried it and nothing changes. I did this as postgresql manual recomended. This query worked fine when I used Oracle XE. But I'm trying to migrate to postgresql because of the partitioning feature, which is not available in Oracle XE. My environment: Postgresql 8.3 Windows Server 2008 Enterprise 64-bit JRE 1.6 64-bit Spring 2.5.6 Postgresql JDBC Driver 8.3-603

• How cross-platform .Net framework really is?

  - by Ivan

  What is normally to be done to run a WinForms application on a Mac or Linux machine? a. Just copy and run (assuming they have a Framework installed). b. Rebuild. c. Cosmetic source code modifications. d. Heavy source code modifications and forms redesign. Assuming that the application is developed as 100% managed C# 3 code by means Visual C# Express or Visual Studio 2008 targeting .Net Framework 3.5, developed without using any 3-rd party components/libraries, without encapsulating nonmanaged code or any low-level hacks - only standard Microsoft-documented .Net Framework C# API used). Or the same conditions but C# 4 language, .Net Framework 4 and Visual Studio 2010.
