• SDruelinger Microsoft Excel 2003 interop + COM object releasing

  G'day, I recieved an unusual error message from a VB.net 2005 application that automates excel and wanted to confirm the correct way to shut down excel automation components. The user got a new PC the other day and started to get the following error messages. 'Creating an instance of the COM component with CLSID {00020820-0000-0000-c000-000000000046} from the IClassFactory failed due to the following error: 80010105'. So I assume this is an Microsoft Excel 2003 automation error. I reviewed the code and found a cross post http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=344206&SiteID=1 suggesting that GC.Collect() should be Marshal.ReleaseCOMObject(objExcelApp). Is that correct for a Microsoft Office PIA component Here ...Show All

• Jassim Rahma how to use a cs files objects at runtime?

  I have a program that creates a cs file. I would like to access it's classes at runtime and create objects of it's classes and use them. How should I approach it. Is there a way I can progmatically compile and create instances of it's objects for use Thanks, Devin what you are describing to me is an OO - Object Oriented. Yes you can create class objects, access its methods and properties. Example: private string theName; public string TheName { get { return this .theName; } set { this .theName = value; } } public class MyClass( string name) { this .theName = name; } public override string ToString() { return this .theName } //some other class: MyClass theC ...Show All

• SDixon updating a data table -----Help Needed very urgently..........!!!!

  hi, I have my database stored in the sqlserver 2005. Using the table name i am retrieving the table and it is displayed to the user in the form of datagridview.I am allowing the user to modify the contents of the table, including the headers. Is it possible for me to update the table straightway rather than giving a sql update command for each and every row of the table . Pls reply asap.... -Sweety you could but i would not recommend it as it will be expensive calling the update method everytime on say a cell value change, what happens if the cell value does not change (user undo's the edit they made) it will still call the update method, pretty much kind of making the entire section of the ...Show All

• Orion77 Finalizer guarantees for access to other objects

  When a finalizer runs are there any gurantees that any other object has not already been finalized This would include another object to which a reference in the finalizer's class still exists or a public static object in the finalizer's class, or any other class. Plop69 wrote: nope, there aren't. Let say you have a object A, that have 2 private members of types B & C. B & C do not have a finalizer in my example public class A { private B _b = new B(); private C _c = new C(); public A(){} ~A() { //here in my finalizer i want to use _b en _c } } static void Main() { A a = new A(); System.Threading.Thread.Sleep(5000); a = null; GC.Collect() } let's sa ...Show All

• Anders Gran&amp;#229;ker How to Run .NET Executable on a Network Drive?

  I'm sure this is very basic. I have an application, a very basic C# Windows Form test application that runs when I execute locally. However, when I copy it to a mapped network drive, such as S: I see this: Unhandled Exception: System.Security.Policy.PolicyException: Unverifiable assemb ly 'S:\Andrew\test.exe' failed policy check.

• Lbo Sleep() api in MainThread...?

  New to C#...coming from C++ and MFC.... Is there a Sleep() api/method to put the main thread to sleep for so many milliseconds Thank you Thank you so much; yep that is exactly what i am looking for have a great day This thread is off topic for the Visual C# Language forum, moving to .NET Base Class Library forum. As has been pointed out, there is the Thread.Sleep() method; but, it's generally misused. If you're looking for thread synchronization this isn't the method to use. If you're looking to put a thread into a wait state, this also isn't the method to use. Only if you want your thread to block and not be able to do anything else for a minimum amount of time (generally in 10-15ms increments, the system ...Show All

• technica Internal vs. Public

  Sorry if this is simplistic, but is it a viable design choice to restrict visibility of as many type members as possible in a Windows application exe to internal, rather than public This client will necessarily never be consumed by any other class or application. It also suppresses various VS warnings about uncommented members, which are irrelevant anyway in many cases. Thoughts, comments Obfuscator I see no request for obfuscation mentioned anywhere in this thread. However, obfuscators can rename public classes too . Hello All. huysmans: That's what internal scope is meant for. Visibility throughout the assembly, but not outside of it. HTH. Thanks for all the comments. I thi ...Show All

• Seekaye Side by Side Execution.

  Hello, Please can you confirm whether the following statement is true: If a .Net 1.1 application runs on a machine with both 1.1 and 2.0 runtimes installed, the application will try to run in the 2.0 runtime. In other words, if you don't configure an application to target a specific runtime, it will use the latest runtime installed on the machine. Thanks in advance. paulballard wrote: This is what I have read on MSDN but the behaviour I have seen in our production environment shows that the 1.1 application is trying to run in the 2.0 runtime. Strange, that's not what I'm seeing. At least not as long as the 1.1 framework is installed. paulballard wrote: Is ther ...Show All

• ramsk SSL Certificate not working without Visual Studio installed?
