Dynamic Type Definition - Error: Type PropertyType Is Not Defined
Mar 11, 2011I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]

Mar 28, 2012I am trying to generate a report using Crystal studio that takes a public variable from the vb.net application. I think the best way to do it is to just dynamically give the filter to the report at runtime, but I can't figure out how to set it up to take any information at runtime.

View 4 RepliesConversion From Type 'DataTable' To Type 'String' Is Not Valid
Aug 9, 2011i encounter this error while passing a string as datatable.
I populate combobox1 with tables/sheets from excel and each table has datarows which i want to get the data and import to sql corresponding table, so, I declare
Dim XLSTableName as String = Combobox1.SelectedItem
And I encounter the this error : Conversion from type 'DataTable' to type 'String' is not valid
how do i return the combobox1.SelectedItem as Datatable cos if i declare

Dim objCmdSelect As New OleDbCommand("SELECT * FROM [" & XLSTableName & "], ODBConn)
to obtain the dataRows I got the following error: operator '&' is not defined for types 'String' and System.Data.DataTable'

View 1 RepliesVS 2008 : Add Dynamic Data To Datatable?
Oct 4, 2010I am creating a data logger that pulls data from an existing OPC server. When the data logger is launched, I look into the OPC server and get the names of the sensors that need logging (ColumnNames() as string) . From that, I am creating a data table with columns based on the items in ColumnNames(). That part is working. What I am having problems with is adding rows to the table. When I read the values from the OPC server, I get an array of strings (values() as string) which is guaranteed to be in the same order as the ColumnNames.I have been trying to use an SqlDataAdapter with a dynamically built insert command, but it is getting extremely convoluted and ugly.Is there an way to add a data row to my table using an array of string values directly?
View 5 RepliesDB/Reporting :: Dynamic Crystal Report Including Parameter Value
Jan 16, 2009This for a semi-automated application. Basically the user provides a list of parameters (entered as an offline spreadsheet). The application automatically selects the required report and logon information. Each line in the given spreadsheet will be used as parameter values for a certain report.Therefore the requirements for this (vb.net) applicaton include:
- dynamically select a different Crystal reports
- each report may read data from different tables from an Oracle database.
An old application of mine that had done something similar and it works normally. Those Crystal reports retrieve data from a SQL server stored procedure. (The stored procedure reads data from Oracle using linked server concept). I do not have to set the logon information dynamically in the vb.net code because every report uses Trusted Windows logon concept. The application can also pass dynamic values to different Crystal report parameters without problems.Then I modify this old application for the required new set of Crystal reports. Because these reports access Oracle database via ODBC and not every report reads from the same Oracle schema, it appears I have to write codes to pass ODBC Dataset and its logon information (the users do not want enter it everytime). The application does not run after the change. The report printout shows blank. Although I can accomplish what is needed by modifying each report to use Stored procedure. But this is not prefered and not a simple task because of the number of reports.I have tested each report and it does run normally in interactive mode.I am not sure if I need to write codes to set the datasource for these 'new' Crystal reports. In my test codes I set the reportsource for my CrystalReportViewer object to an non-typed report. Is there anyone who can show me sample codes that
1) achieve odbc logon
2) select a report dynamically for preview/printing
3) pass values to parameter
Linq Over Datatable Using Dynamic Library Sample?
Nov 3, 2009I am looking for sample linq code snippet which uses System.Linq.Dynamic against a datatable.

Dynamic List From DataTable.Select Rows Collection?
Jun 6, 2011I'm am creating a "pop-up" CheckedListBox over a button on my DataGridView. The values in the list are going to be filtered based on the value in column 0 of the DataGridView.I have already pulled in a "master" DataTable with two columns: ACODE and MATRIX.I want to call the following function and return an array of strings that I can use to build this CheckedListBox with. The line between "For Each r" and "Next" generates a "Number of indices is less than the number of dimensions of the indexed array". The number of items is variable in the array so I can't predefined it. I know I'm going down the wrong path.
