Reporting Services - Handling An Empty Date?
Jul 14, 2010
I have a report parameter which looks like this: 01.01.2009 00:00:00.Its a date (as string), as you might have guessed :). The problem is, this param can be an empty string as well. So I tried those expressions:
=IIf(IsDate(Parameters!DateTo.Value), CDate(Parameters!DateTo.Value), "")
=IIf(Len(Parameters!DateTo.Value) > 0, CDate(Parameters!DateTo.Value), "")
Both dont work and the value for the textfield where I print the expressions result is always #Error. As soon as I remove the CDate stuff, it works, but I have to use it. IS there another way to achieve that? What I want is to display nothing if its not a date or the date (format dd.mm.yyyy) if its a date.

I have a matrix with rows indicating a name (Ex Store name) and I have data pertaining to that in the DATA cells. I also have another date field in this format (MM/DD/YYYY). I would like to use a cross tab between Store Names and Just the Month of the date field.
[code]...
is there any expression I can use to get the month format on the header of column.

Can these two things work together? That is VB.Net Standard NOT VB.net 2005 or vb.net 2008 or any other year. If not is there an inexpensive solution for reporting in VB.Net Standard and SQL server?

We have a VB.NET (aspx) website with a login first page. Once the user has logged in and is authenticated they are taken to a single page with a Menu Bar at the top and a report viewer control underneath. When the user has logged in the report viewer is initially populated by a dynamic menu (a menu of links to other reports depending on each user's permission).
Now, on some reports that the user access from the main menu, they like to export the data. The nicely formatted reports export nicely to PDF but these same reports look awful when you export to excel. Further more what is required from the excel version is no formatting and also to include extra columns of data that are available form the dataset but not from the rendered report (for use with importing these expoerts into other systems).
Is it possible to extract the data that is generated from the dataset that renders the report?What I would like to do is obtain this data and create my own excel export option (of which I will put into the page Menu bar at the top of the screen). It is important to just grab the data that is generated because different data is available depending on the parameters the user has chosen.

I have the following code:
public sub PrettyRows()
dim ds as dataset = report.dataset1
dim GroupName as string = ""
[Code]....
The Protected Overrides Sub OnInit() is comparable to the load event in VB.NET.
I am utilizing this event to call my custom sub PrettyRows. This sub will iterate the rows in my dataset and change the first column in each row so that an entry only appears once, This is being utilized to identify what group the row belongs to. The rows are sorted by group and I only wish to display the group name once and I am removing all other references to the group name.

We are trying to add SQL Reporting Services to a .Net 2.0 Web Application. SRS has been installed on the server successfully, but we get an error when we try to load a report or access the report manager:
Server Error in '/Reports' Application.Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Could not load file or assembly 'netGmrc' or one of its dependencies. The system cannot find the file specified.
The error is being coming from a line in the web.config where an httpHandler called Upload.axc is being added to the web application. The entire httpHandler section is listed below.
<httpHandlers>
<add verb="*" path="Upload.axd" type="netGmrc.Upload, netGmrc"/>
<remove verb="*" path="*.asmx"/>
[code]....
When we remove the Upload.axd handler from Web.Config, everything in SRS works fine. What is the proper way to have Reporting Services work along side the web application with this httphandler?

I'm using Reporting Services 2005 to produce a one-time report that will group records according to the PLANCODE field. I've created the following VB function:
[Code]...
How do I reference the above function in a new calculated field so that the report will group data based on the results of this function? The doucmentation states that the expression should be something like =code.PayorGroup. However, when I try this expression in the Calculated Field window, I get the infamous red squiggly line stating Unrecognized Idnetifier.

What is the best way to launch reporting services reports from .Net code? One method would be to dynamically build a URL and launch a browser. Something like this:
http://server/ReportServer/Pages/ReportViewer.aspx?%2fReport+Directory%2fReport%20Name&FirstParameter=1,2,3&SecondParameter=8/30/2009&rs%3aCommand=Render

I have a function in SSRS using VB.NET as follows: Public Function GenerateCSV(byval str as string, byval str1 as string, byval str2 as string, byval GrpName as string)
[Code]...
This works great is str, str1 and str2 have a value and only one value. But I want to make it so if the value isn't there or there is only one value there is no comma and if there are multiple commas there is a comma.

We are planning on creating reports to be run on the same computer that the database application is running on. which of these is the best approach? (SQL Server Reporting Services or creating a rdlc ReportViewer report) Also I tried to locate detailed rdlc ReportViewer report tutorials both in books and online and found none. It's probably because I'm looking in the wrong places.

I use VB in Visual Studio 2008 Pro. I've created a few solutions using the Crystal Reports tools. I found them easy to work with & easy to do things, (export to different formats, refresh reports, write an automated service that ran & saved reports, etc...)Is CR in VB 2010? If so - which version of VS 2010 do you need to buy to get it?OR - is the reporting services in VS a suitable replacement? Is there a viewer / preview like the CR tools? Can you create a standalone app to refresh reports & export them to different formats? Which version of VS 2010 would I need to purchase to get these?At home - I use Win 7 media centre (a fantastic piece of software). Are there any development 'goodies' in Visual Basic 2010 for Win 7 Media Centre?

I am trying to build a report using MS reporting services (rdlc file) and having trouble figuring out syntax to take calculated data from a textbox in table1 to table2. In other words, I have totals calculated in table1 and I need to display those totals in another table (table2) and/or a text box outside of table1.
I have tried versions of =ReportItems!TextBox37.Text and =ReportItems!TextBox37.Value and =ReportItems("TextBox37").value etc. but with no luck. The last thing =ReportItems("TextBox37").value does compile but it prints #error on the report.

I have a DataGridView to which I've set a list of objects to the DataSource. (I'm in VS 2005 using VB.) I created the DataGridView by creating a Data Source of type AssetIdentifier and dragging that Data Source onto my form. I want to update the DataGridView when the selection in either a combo box or another DataGridView changes. (Below I'm considering a click in another DataGridView.)
The following works:
Public Class dlgShowAssets
' class member variable
Private assetIdList As List(Of AssetIdentifier)
' pertinent subs and functions
Private Sub RefreshAssetIdentifierDataGridView()
[Code] .....
In this case, I always knew that assetIdList would have at least one element. I'd update the list, and reset the data source of the DataGridView to that list, and all was well. When I applied this to another situation, for which I couldn't guarantee that the list would have at least one element, things would work fine as long as I had at least one element in the list, but if the list became empty, the DataGridView threw System.IndexOutOfRangeException a number of times.
The rows in the DataGridView would not go away if I went from a non-zero number of elements to zero. I tried a workaround, which was to remove all of the elements, add one "dummy" element, and then re-bind the list to the control and it still didn't work. Also, following all of those exceptions, I'd get other similar exceptions when I hovered over the cells in the DataGridView. Some of the members of AssetIdentifier were "Nothing" but I fixed that in the constructor, and the exceptions still occur.

Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.
[Code]...
I have been programming steady with vb.net for a year now and was all happy about using the List view and email etc from web sites. I even used a reportviewer to pdf to email attach, cool. Now I feel quite lost and realize I have not been using properties, etc. That is my background.

I have an input parameter for my stored Proc, Instead of choosing available values from a drop Dwn, the customer wants an empty input box that when left blank returns all records. the parameter type is numeric(6,0) in the Db. I have not found a way to leave the input blank and retrieve all records. my default value for all records is '-99' and also is declared as the default value for the param in the proc.

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

I am currently working on a silverlight project with RIA Services and have seem to come across a bug(or wrote a new one).In a simple query I am retrieving a entity model from the server. In the server side service class a DateTime is correct(to what's in the db) but on the client it seems to go back 24 hours and maybe 10 hours...6/04/2009 12:00:00 AM (Database) turns into 5/04/2009 2:00:00 PM and also displays as 5/4/2009 12:00:00 AM.

I have a stored procedure (SQL Server Express) that returns a count of records:
SELECT COUNT(AdminUserID) AS CountEm
FROM Licenses
WHERE (AdminUserID = @AdminUserID);
Table "Licenses" has a field "CompanyID" which is a uniqueidentifier.
I need to add a clause to the WHERE to exclude records from the count where "CompanyID" is null/empty.
In VB code I'd do this with "If Not (TheCompanyID.Equals(Guid.Empty)) Then"
How would I do this in a stored procedure?

I was wondering what is the best way to make sure a date is 'empty' so that, if it hasn't been set by the user, that situation is testable.
I've checked and found one way of approaching the issue:
[Code]....
Is the second one more of a stop-gap measure? Is the first way the sanctioned way (which hopefully doesn't entail a lot of complication with testing/setting the values of the date)?

I've got a new instance of an object in a Linq DBML, but don't know of the test if the a date field is empty.I have tried:
If d Is Nothing OrElse IsDBNull(d) OrElse d <= Date.MinValue Then
TextValue = "nada"
Else
TextValue = FormatDateTime(d)
End If
But the result is "12:00:00 am"
edit: Changed variable name the d
edit: note that the SQL field is nullable
