问题 I want make a UI that is semi transparent in WPF VS2008, so I made my form transparent and I want to show a semi transparent png (Which includes "holes") on top of it. How do I show the semi transparent png? Semi transparent, meaning it has holes you can see through. Also how can I get this done in C#, without using WPF. Thanks. 回答1: You should just have to use the Image control and WPF should take care of the rest: <Image Source="myimage.png" /> Or in pure C#: BitmapImage sourceImage = new

问题 I am trying set up transaction but without success.

问题 One would assume with any web-based data application that database transactions would be an integral part of the design. Looking around at CrmService, I can't find anything that suggests that transactional 'CRUD's are available. Is it the case that this is not supported/implemented in MSCRM? If it is, and i have missed it, could someone please point me in the right direction. I fear coding a whole lot of 'repair code' to cater for errors/exceptions half way through a custom import

问题 I am currently in a project where we have a method that is called to generate a report and then return it to the client side. The whole process works something like this: [[Application]] --> [[JMS]] --> [[DB Server]] However, our WebSphere has a global setting where Transaction Timeout is set to 2 minutes, and Maximum Transaction Timeout is set to 5 minutes. This has caused us some problems because some of our reports take longer than 2 minutes, and as such, the connection is dropped at the

问题 I want confirm if the Transaction that Entity Framework's ObjectContext.Connection.BeginTransaction() method returns uses the support of MSDTC (Microsoft Distributed Transaction Coordinator) or not? Is there any way to use transactions without support of MSDTC? 回答1: It will automatically promote to a transaction coordinated by MSDTC under certain conditions. Each time you call ObjectContext.SaveChanges() a new transaction is created if there isn't already one in scope (if there is already an

问题 I am trying to use NHibernate in combination with .NET's TransactionScope object. So far I have successfully used Oracle 11g and SQL Server 2008R2 with no issues. However, SQL Compact seems to fall on its face. using (var scope = new TransactionScope(TranactionScopeOption.Required)) { using (var session = _sessionFactory.OpenSession()) { // The line below throws. I also tried passing in System.Data.IsolationLevel.ReadCommitted to no avail using (var txn = session.BeginTransaction()) { //

问题 I am using Spring transaction management to control a application with hibernate, it uses two instance of threads to access concurrency database and modify one table.

问题 Is it possible to make a MySQL transaction that changes databases on different servers? I would need to: insert into the first database select from the first database insert into the second database if any of these fails, revert to the original state 回答1: As observed above, this question is very similar to Can I to a transaction across two MySQL databases? Whilst that question referred to different databases on the same server, its accepted answer still applies. Indeed, as documented under XA
