  • RDLC: Is there a way to print multiple tables without SubReports?

    - by Eduardo Molteni
    I'm generating the RDLC XML schema and showing the report in the ReportViewer control. No problems there. Now, I want a report with 2 tables, with 2 differents dataset. Something like this gets generated: <Body> <ReportItems> <Table Name="Table1"> .... </Table> <Table Name="Table2"> .... </Table> </ReportItems> </Body> But, when printed, both tables start from the top, printing on table over the other (not nice) Is there a way to tell that Table2 should start after Table1? Update: I've tried with List with a fake DataSource, but it does not work.

  • Inner Join with more than a field

    - by Leandro
    Precise to do a select with inner join that has relationship in more than a field among the tables Exemple: DataSet dt = new Select().From(SubConta.Schema) .InnerJoin(PlanoContabilSubConta.EmpSubContaColumn, SubConta.CodEmpColumn) .InnerJoin(PlanoContabilSubConta.FilSubContaColumn, SubConta.CodFilColumn) .InnerJoin(PlanoContabilSubConta.SubContaColumn, SubConta.TradutorColumn) .Where(PlanoContabilSubConta.Columns.EmpContabil).IsEqualTo(cEmp) .And(PlanoContabilSubConta.Columns.FilContabil).IsEqualTo(cFil) .And(PlanoContabilSubConta.Columns.Conta).IsEqualTo(cTrad) .ExecuteDataSet(); But the generated sql is wrong: exec sp_executesql N'/* GetDataSet() */ SELECT [dbo].[SubContas].[CodEmp], [dbo].[SubContas].[CodFil], [dbo].[SubContas].[Tradutor], [dbo].[SubContas].[Descricao], [dbo].[SubContas].[Inativa], [dbo].[SubContas].[DataImplantacao] FROM [dbo].[SubContas] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[CodEmp] = [dbo].[PlanoContabilSubContas].[EmpSubConta] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[CodFil] = [dbo].[PlanoContabilSubContas].[FilSubConta] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[Tradutor] = [dbo].[PlanoContabilSubContas].[SubConta] WHERE EmpContabil = @EmpContabil0 AND FilContabil = @FilContabil1 AND Conta = @Conta2 ',N'@EmpContabil0 varchar(1),@FilContabil1 varchar(1),@Conta2 varchar(1)',@EmpContabil0='1',@FilContabil1='1',@Conta2='1' What should be made to generate this sql? exec sp_executesql N'/* GetDataSet() */ SELECT [dbo].[SubContas].[CodEmp], [dbo].[SubContas].[CodFil], [dbo].[SubContas].[Tradutor], [dbo].[SubContas].[Descricao], [dbo].[SubContas].[Inativa], [dbo].[SubContas].[DataImplantacao] FROM [dbo].[SubContas] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[CodEmp] = [dbo].[PlanoContabilSubContas].[EmpSubConta] AND [dbo].[SubContas].[CodFil] = [dbo].[PlanoContabilSubContas].[FilSubConta] AND [dbo].[SubContas].[Tradutor] = [dbo].[PlanoContabilSubContas].[SubConta] WHERE EmpContabil = @EmpContabil0 AND FilContabil = @FilContabil1 AND Conta = @Conta2 ',N'@EmpContabil0 varchar(1),@FilContabil1 varchar(1),@Conta2 varchar(1)',@EmpContabil0='1',@FilContabil1='1',@Conta2='1'

  • Translate google co-ordinates to the pixels on picture.

    - by kalininew
    I have a city "map" (for example - Moscow). She in accuracy repeats the contours the given city in google maps (that is it is copied from google maps and it is a little processed, but the sense remained the same). Also I have object co-ordinates in a city (in co-ordinates of google). Problem: how to translate google co-ordinates to the co-ordinates of my picture (that is in pixels on OX and OY on a picture). That is I receive google-co-ordinates and it is necessary for me to draw this point on my picture. I know that on small scales (for example on city scales) it to make simply enough (it is necessary to learn what google-co-ordinates has one of picture corners, then to learn "price" of one pixel in google-co-ordinates on a picture on axes OX and OY separately). But on the big scales (country scale) "price" of one pixel will be not a constant, and will vary strongly enough and the method described above cannot be applied. How to solve a problem on country scales?

  • WCF Paged Results & Data Export

    - by Ben
    I've walked into a project that is using a WCF service for the data tier. Currently, when data is needed for a grid, all rows are returned and the results are bound to a grid and the dataset is stuffed into a session variable for paging/sorting/rebinding. We've already hit a max message size problem, so I'm thinking it's time to convert from fetch and cache to fetch only the current page. Face value this seems easy enough, but there's a small catch. The user is allowed to export the entire result set at any point. This means that for grid viewing purposes fetching the current page is fine, but when they want to do an export, I still need to make a call for all data. This puts me back into the max message size issue. What is the recommended approach for this type of setup? We are currently using the wsHttpBinding... Thanks for any assistance.

  • When should assertions stay in production code?

    - by Carl Seleborg
    Hi all, There's a discussion going on over at comp.lang.c++.moderated about whether or not assertions, which in C++ only exist in debug builds by default, should be kept in production code or not. Obviously, each project is unique, so my question here is not so much whether assertions should be kept, but in which cases this is recommendable/not a good idea. By assertion, I mean: A run-time check that tests a condition which, when false, reveals a bug in the software. A mechanism by which the program is halted (maybe after really minimal clean-up work). I'm not necessarily talking about C or C++. My own opinion is that if you're the programmer, but don't own the data (which is the case with most commercial desktop applications), you should keep them on, because a failing asssertion shows a bug, and you should not go on with a bug, with the risk of corrupting the user's data. This forces you to test strongly before you ship, and makes bugs more visible, thus easier to spot and fix. What's your opinion/experience? Cheers, Carl See related question here

  • Does DataAdapter.Fill() close its connection when an Exception is thrown?

    - by motto
    Hi, I am using ADO.NET (.NET 1.1) in a legacy app. I know that DataAdapter.Fill() opens and closes connections if the connection hasn't been opened manually before it's given to the DataAdapter. My question: Does it also close the connection if the .Fill() causes an Exception? (due to SQL Server cannot be reached, or whatever). Does it leak a connection or does it have a built-in Finally-clause to make sure the connection is being closed. Code Example: Dim cmd As New SqlCommand Dim da As New SqlDataAdapter Dim ds As New DataSet cmd.Connection = New SqlConnection(strConnection) cmd.CommandText = strSQL da.SelectCommand = cmd da.Fill(ds)

  • Function parameter types in Python

    - by Leif Andersen
    Unless I'm mistaken, creating a function in python works like this def my_func(param1, param2): /*stuff*/ However, you don't actually give the types of those parameters. Also, if I remember, python is a strongly typed language, as such, it seams like python shouldn't let you pass in a parameter of a different type then the function creator expected. However, how does python know that the user of the function is passing in the proper types? Or will the program just die if it's the wrong type, assuming the function actually uses the parameter? Or do you have to specify the type/I'm missing something? Thank you.

  • DataBinding: ComboBox.Text not updating when SelectedValue changes?

    - by Rob
    This is the relevant designer code for the ComboBox: Me.ProbationComboBox.DataBindings.Add(New System.Windows.Forms.Binding("Enabled", Me.RegistrationBindingSource, "IsRegistered", True)) Me.ProbationComboBox.DataBindings.Add(New System.Windows.Forms.Binding("SelectedValue", Me.RegistrationBindingSource, "ProbationID", True)) Me.ProbationComboBox.DataSource = Me.ProbationBindingSource Me.ProbationComboBox.DisplayMember = "probation" Me.ProbationComboBox.ValueMember = "id" The problem is that when I call RegistrationBindingSource.ResetCurrentItem(), the SelectedValue property is refreshed with the correct value from RegistrationBindingSource.ProbationID(). However, the Text property is not updated. Until I can figure out the problem with my binding, I've been doing this as a fix: Me.ProbationComboBox.Text = CType(CType(Me.ProbationBindingSource.Current, DataRowView).Row, RootNamespace.DataSet.probationRow).probation Any ideas? Your assistance is appreciated!

  • Retrieving cached data from existing Crystal Reports file

    - by TimS
    Is there any way to retrieve the cached data from a previously refreshed report and say, dump it to a file? Basically, I'm looking for the dataset that is being used by the report, and hand-dragging each field onto the canvas or even exporting the file doesn't quite get me where I want. I'm not particular to a specific solution, be it .NET, vbscripting or even within the program itself... I'm not overly familiar with the Crystal Report object model, nor .NET, but it seems like with a setting like "EnableSaveDataWithReport", there ought to be a straightforward way. Oh, and I'm on CR 11 Pro

  • jQuery dynamic field classes not being assigned as desired.

    - by Simon
    Hello, I'm working on a fancy login page with 4 unique states attributed through classes for each field (normal, focus, active-on, active-off). Normal is the default style. Focus is the focus style when nothing is typed. Active-on is the focus style when something has been typed. Active-off is for field that have user text in them, but are not focused right now. Here's a demo to help you understand what I'm doing: http://www.controlstack.com/login My JS is working almost correctly (thanks to some folks on this site), except in 2 cases: If I enter something in the username field, then tab over to the password field, it does not add the ".focus" class to the password field. If I blur out of the username field, then focus back on it, enter a few characters, then delete them, it does not add the ".focus" field.

  • Microsft Jet oledb connection to excel loses formulae

    - by Saubhagya
    I have a dataset and I write it's values to an excel file using Microsoft Jet 4.0 Oledb provider. I want to put hyperlinks into the excel, for this I write "=HYPERLINK("http://www.abc.org/x.pdf")" in DS and then write it to excel. But when the excel is opened it prefixes a ' (quote/apostrophe) before the formula and there it comes as a text, not link. Can you help me removing that quote so that my excel file has hyperlinks instead of that as text? I need to use Microsoft Jet 4.0 provider (not excel component) as the client machine may or may not have MS-Excel installed on his machine.

  • Accessing XML data online?

  • how to change strip.text labels in ggplot with facet and margin=TRUE

    - by Andreas
    I have looked here but still can't figure it out. How do I change the strip.text.x labels in a ggplot with faceting? Specifically I am using facet_grid with margins. The strip.text label for the margin is "(all)" - but since I am in a non-english speaking country I would rather write "Total" or something similar in my native tongue. opts(stip.text.x=c(levels(facetvariabel,"Total")) does not work. Any ideas? Example (not really the best dataset for this - but I guess it will work) ggplot(cars, aes(x=dist))+geom_bar()+facet_grid(.~speed, margin=T)

  • Strong name validation failed on VB.NET Assembly

    I have a VB.Net 1.1 application works just fine after compiling in Visual Studio. However, I want to use ILMerge to combine all the referenced assemblies into a single executable just to make it easier to move around. After I send it through ILMerge and try to run it I get the error "Strong name validation failed for .exe" ..... But none of my stuff is strong named! I saw this post here: http://stackoverflow.com/questions/403731/strong-name-validation-failed and tried running it through 'sn.exe -Vr .exe' but that gives me this error: ".exe does not represent a strongly named assembly" Has anyone else had this problem before? How do I fix it?

  • Current ways to do data binding in .NET 3.5 with C# 3.0 and WinForms

    - by kryptic
    Hello Everyone, I have an existing C# 3.0 WinForms project with .NET 3.5 that talks to a MySQL database. I would like to use data binding (I'm new to this, so I've been doing all of the UI updates manually) to simplify things. I followed a link from this question to this article which mentions using a DataSet but also follows up with "my view on this topic is strongly in favor of Business Objects." Also that was with .NET 2.0. What are the current methods to use data binding with a WinForms application? What are their advantages in terms of simplicity, how much additional code is necessary, etc. For reference, I use an ORM approach to build objects with public properties from a database. I want to map these properties for each object onto UI elements like TextBoxes. There could be many properties for an object so I want to simplify the code to do this.

  • Using transactions with ADO.NET Data Adapters.

    - by Ergwun
    Scenario: I want to let multiple (2 to 20, probably) server applications use a single database using ADO.NET. I want individual applications to be able to take ownership of sets of records in the database, hold them in memory (for speed) in DataSets, respond to client requests on the data, perform updates, and prevent other applications from updating those records until ownership has been relinquished. I'm new to ADO.NET, but it seems like this should be possible using transactions with Data Adapters (ADO.NET disconnected layer). Question part 1: Is that the right way to try and do this? Question part 2: If that is the right way, can anyone point me at any tutorials or examples of this kind of approach (in C#)? Question part 3: If I want to be able to take ownership of individual records and release them independently, am I going to need a separate transaction for each record, and by extension a separate DataAdapter and DataSet to hold each record, or is there a better way to do that? Each application will likely hold ownership of thousands of records simultaneously.

  • Hiding Table Rows

    - by David Stein
    I have a table that I'm using to show details from the line items of a quote. I want to hide a particular row depending on the value of the field in it. The expression I've tried is to set the row visibility to: =IIF(isnothing(First(Fields!NEW_PRICEBREAKS.Value, "QuoteDetail")),true,false) When I run the query from the dataset "Null" returns for NEW_PRICEBREAKS for most of the records. Also, when I expanded the row with another column with this expression: =IIF(isnothing(First(Fields!NEW_PRICEBREAKS.Value, "QuoteDetail")),"is nothing","not nothing") I see "not nothing" repeated over and over again. I've attempted to use TRIM inside of the isnothing to remove spaces and it still doesn't work. Also, the sql data type for NEW_PRICEBREAKS is nvarchar(MAX). Any ideas how I can suppress this row correctly?

  • Optimizing a large iteration of PHP objects (EAV-based)

    - by Aron Rotteveel
    I am currently working on a project that utilizes the EAV model. This turns out to work quite well, but like many others I am now stumbling upon some performance issues. The data set in this particular case consists of aproximately 2500 entities, each with aprox. 150 attributes. Each entity and each attribute is represented by a PHP-object. Since most parts of the application only iterate through a filtered set of entities, we have not had very large issues yet. Now, however, I am working on an algorithm that requires iteration over the entire dataset, which causes a major impact on performance. This information is perhaps not very much to work with, but since this is an architectural problem, I am hoping for a architectural pattern to help me on the way as well. Each entity, including it's attributes takes up aprox. 500KB of memory.

    Thanks in advance for any and all assistance. My code is: Public Function StripHTML(value As String) As String Return System.Text.RegularExpressions.Regex.Replace(value, "<(.|\n)*?", "") End Function Then I call the function from a textbox. This works great unless there are nulls in the dataset. I tried to compensate for the nulls, but the RDLC file generates an error message that it can't display the subreport. Public Function StripHTML(value As String) As String if isnothing(value) then return value else Return System.Text.RegularExpressions.Regex.Replace(value, "<(.|\n)*?", "") end if End Function I also tried to tell it to return " " if null. I had no luck... Any ideas? and thanks again.
