• Visual C# Maintaining an Activity Log over multiple classes

  Hi all, i have a class called ActivityLog.cs and this basically creates a log of whats going on in my console app. i construct it like: ActivityLog Activity = new ActivityLog(); then you use it like activity.log("this is one entry"); and when the program is done you can mail out the log like activity.Email("me@me.com","me@you.com","the log file"); My program uses three different classes, right now the activity log only works with the first, well it will work with all three but only if i construct a new log file for each class, i was hoping someone could help me figure out a way to pass the log back and forth during the execution of the different classes.

• Visual Studio 2008 (Pre-release) Is this a bug of drag and drop with right mouse button in WPF?

  Dear Experts, My team is blocked by a confusing issue about the drag and drop function in WPF. In our application, the ListView is used and the target is to drag items out of the ListView control. We succeeded in implementing the drag and drop with mouse left button but the right button doesn't work . Isn't the left button and right button "equal" in dragging of WPF Or anything important we missed Somebody told me that this was a bug of WPF in supporting drag and drop. I am not sure. BTW, there is also a smaller issue: With multiple items selected in the ListView control, when the mouse button is pressed down again to begin dragging, all of the selected items except the pressed one become unselected again. Do you know how to ...Show All

  I am unable to run the sample applications that come with the SDK's for DirectX 8 or 9 that were written for Visual Studio 2005 Visual C++.

• Visual Studio Team System Add New Project to Solution under source control

  Hello, I have a Solution under Source Control. Since today, when I try to add a new project to the Solution, the solution.sln file is not check-out and the new project does not appear in the pending changes window. Also, I have realized that since today, there is a new option when I click on any Solution file: "Add Solution to Source Control..." when the Solution is already in the Source Control.

• SQL Server Parameters in a OleDb Command Transformation

  Hi there, In order to prevent lookup errors in a lookup transformation, I've decided to go for an OleDb Command Transformation. This transformation should check the lookup and, if it turns out to be null, ir returns a dummy value. Otherwise, it would return the lookup value. This should be done by doing something like this: select coalesce( (select ID_Table2 from ID_Table2 where FK_Table1 = ), 0) suposing Table2 has an atribute called "FK_Table1" that should match a column in the data flow. Now, such command result in this message: " An OLE DB record is available.

• Visual Studio 2008 (Pre-release) WCF call fails sometime in CAB application

  We are currently developing a software using both CAB (Composite Application Block) and WCF. The client side GUI is written based on CAB. However, it is found that if WCF callback is used, sometime WCF client side call will raise "TimeoutException" exception. I have checked the WCF log file and found that before the exception was raised, the message was already received by the client side; but for some reason, the message was not processed until timeout. If I not to use CAB, it seems everything works fine. I think a dead lock could be generated by ObjectBuilder, which is the main part of all the application blocks. I have wrote a small test program which has the exactly same problem. I cannot locate the problem precisely ...Show All

• SQL Server Automatic failover failure

  Hello, we're running a mirrored database with High Availability for Automatic failover including a Witness instance for a web application. When doing a manual failover on the database in Management studio, the roles are switched correctly and the database is in "Principal, Synchronized" and "Mirror, Synchronized/Restoring" mode. The web application has no problems switching servers by using client failover with the jdbc driver. There is no problem accessing the database with Management Studio. However, if we stop the SQL service on the Principal server the role is automatically failed over to the Mirror server by the Witness. The database is then in the mode "Principal, Disconnected" which should be f ...Show All
