Smart Device Development PDA reboot to re-run application?!!
Hi guys, I've encountered a little problem. I've developed a program in C# to be run on a PDA. I got it successfully setup and installed on the PDA, but when i run the program it runs once. At that point if i close the program it doesn't run again until i do a reboot (soft reset) of the PDA. Any ideas on how i can get around this problem Thank you Thank you, That was very helpful, the problem was that i was hiding one of the forms which did not close when the program terminated and that was the startup form , making it impossible to restart the program. Thanks again. ...Show All

.NET Development svcutil
Hi All, I'm starting studying WCF and svcutil can be used to generate the classes to connect to a given WCF service: including the service contract, WCF client and data contract (all in a single file). Is there any way to make each class generated on a single file I was thinking about having the client accessing several services that uses common contracts (sharing the same class). If I try to import the generated code into my client for these services I will have conflicts, won't I Thanks a lot! PS: Sorry if the question is not very clear. Please let me know and I'll try to formulate it better... Thanks, It worked! Altouigh I think it would be better to have my interface and my W ...Show All

Visual C# Multi Interface inheritance
Lets say you have two interfaces: interface IA: IComparable { int A {get; set;} } interface IB: IComparable { int B {get; set;} } and a class which implements both IA and IB class C: IA, IB { } class C now has to implement CompareTo, but the problem is that CompareTo should do different things if being used to compare this object to another IA, IB or classC. How do you implement the CompareTo function For instance lets say there is code like this: C c1 = new C(); C c2 = new C(); IA ia = c2; int comp1 = c1.CompareTo(ia); int comp2 = c1.CompareTo(c1); In this case, comp1 should equal 0 if c1.A == c2.A, and comp2 should equal 0 if both c1.A and c1.B are equal to c2.A and c2.B. Since you can only have one CompareTo method on class C how do ...Show All

Visual Basic MsgBox always return "no" regardless of what the user click
I am using VS2005 and have a messagebox inside of an event that does not work properly. The code is below: If Microsoft.VisualBasic.MsgBox( "Do you want to save your changes" , MsgBoxStyle.YesNo) = MsgBoxResult.No Then Exit Sub End If The problem is regardless of whether the user clicks Yes or No, it always returns No. If I add another MsgBox in the code immediately before the if statement, then the if statement will always work properly.

SQL Server auto-commit vs begin transaction overhead
I've googled for the answer and searched sql server 2005 books online and I haven't been able to find the answer to my question. My main question is what is the difference in overhead between using auto-commit on every statement or explicitly calling begin transaction on every statement. I'm basically looking for documentation that points to the difference. Read on for the scenario... We have an application that has problems with deadlocks. Part of our strategy in handling these deadlocks is resubmitting the transaction. My solution to this part of the strategy is to wrap every storedprocedure in a transaction so this would include reads and writes. My architect has raised some concerns with regard to performance if it's implemented this w ...Show All
