问题 I am trying to set up a 64-bit ODBC data source connection in UiPath, but it's not visible and only showing 32-bit data sources. Is it because UiPath is a 32-bit software? Please suggest an alternate workaround. 回答1: A 32-bit application can only load 32-bit ODBC drivers. Your options are to -- find a 64-bit version of your "UiPath" application find a 32-bit version of the 64-bit "Oracle in XE" driver find a 32-bit ODBC Driver for 64-bit ODBC Data Sources (such as this, from my employer,

问题 I have a problem about binding a form property to a datasource. The solution is given here(Please see): Radio Buttons And Databinding in vb.net The problem is, I do not know how to follow the instruction- "...and then you can simply bind the CarpetColor property on your form to the data source's CarpetColor." Can you show me how to do it? Also, for some reason, I cannot use the "INotifyPropertyChanged" interface (cannot be detected by intellisense). Do I have to import any namespace? Edit:

问题 Goal I want to have a DataGridViewComboBoxCell after setting my DataGridView's DataSource with a DataView. Current Situation I have a DataTable that is populated with BillDetails as the user navigates through his Bills . I created a DataView and set the DataView's Table to equal to the DataTable of Bill Details. I then set the DataGridView's DataSource to the DataView. Setting the DataGridView's DataSource Dim ViewContent As New DataView ViewContent.Table = dsBillMat.Tables("dtBillDetails")

问题 I would like to iterate over all the available dataSources for the current environment, trying to see if any of them contain a particular domain instance. Each environment has different dataSources. The best I've hacked up so far is grailsApplication.config.findAll { it.key.contains('dataSource_') } . Is there a better or more legitimate way to do this? 回答1: You can also query against the bean names in the application context. Something like ctx.beanDefinitionNames.findAll{ it.contains(

问题 We currently have an application which uses multiple databases with the same schema. At the moment we're using a custom solution for switching between them based on the user's session. This works via public final class DataSourceProxy extends BasicDataSource { ... Authentication auth = SecurityContextHolder.getContext().getAuthentication(); if (auth != null && auth.getDetails() instanceof Map) { Map<String, String> details = (Map<String, String>) auth.getDetails(); String targetUrl = details

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . I read this comment: "don't use JDBCRealm at all: it does not scale at all since there is a single JDBC Connection object used for all database communication.
