Hello all. I creates an ASP.NET application using Crystal report with VS2008. I creates Web setup project. MS says I don't need to add any merge module for crystal report on VS2008. But, HOW CAN I Add License key? Do I need License key to deploy on web server? Without license key How many cucurrent users are allowed? (Since it says more than max user requrest will be queued -> I couldn't find what's max?) any comment or link to related documents will helps. Thank you all.

Solution I resolved the issue. I changed ClassInterfaceType to AutoDispatch and it solves it like following. [ClassInterface(ClassInterfaceType.AutoDispatch)] The problem started from .NET1.1. Since ClassInterfaceType.None shouldn't work in .NET1.1 even. However, somehow they changed something or fixed bug in .NET2.0 and it stop work with None for Late binding client. That's why it confued me. Anyhow, thank you all.

Hi all, Since our project have to support legacy VB6 client also, I created COM+ using .NET. First time I create COM+ using .NET 1.1 version. VB6 client calls the COM+ Application class and calls Exectue4VB() method. There was no problem. I test it all and worked as expected. We decided to convert COM+ code using .NET 2.0. However when I converted the code to .NET2.0, it stops work!! So, I created small test COM+ and test vb6 client. It doesn't work. It works perfectly ok with COM+ written in .NET1.1. Error is : Object doesn't support this property or method It's so wired. What is problem? .NET2.0 doesn't support it anymore or what? It's same code. I've searched all around to find related doc. I couldn't find any. Any comment helps. Thank you all. Here is sample code: using System; using System.Collections.Generic; using System.Text; using System.EnterpriseServices; using System.Runtime.InteropServices; namespace DLSBPM2.Engine { [Description("COM+ class.")] [ClassInterface(ClassInterfaceType.None)] [ObjectPooling(Enabled=true, MinPoolSize=4, MaxPoolSize=4)] [Guid("F72E9E0F-CDFF-49A4-858F-889F868DB7F5")] public class Application : System.EnterpriseServices.ServicedComponent { public Application() { } public object Execute4VB(object objs) { return "" + objs + ":" + DateTime.Now.ToLongTimeString(); } } } // I added to COM+ like following regasm DLSBPM2.Engine.dll /tlb DLSBPM2.Engine.tlb gacutil /i DLSBPM2.Engine.dll regsvcs /tlb:DLSBPM2.Engine.tlb DLSBPM2.Engine.dll //And VB6 client Code sample Option Explicit Private Sub Command1_Click() Dim myApplication As Object Set myApplication = CreateObject("DLSBPM2.Engine.Application", "myserver") Dim result ' following line of code throw Error with .NET2.0 COM+ ' : Object doesn't support this property or method result = myApplication.Execute4VB("this is test") MsgBox result End Sub

Hi, all. I have problem with COM+. I created COM+ with C#.NET. I have to call this COM+ from window application(in C#.net) remotely using late or early binding. I called COM+ with late binding, it throws 'Method not found' exception. And I don't know how to do early binding. I didn't have problem to calling COM+ written in VB. I add reference from COM tab. It works ok. However, when I try to add reference of COM+ written in C# from COM tab, it throws error message, "A reference to 'COMPlusServer2003' could not be added. Converting the type library to a .NET assembly failed. Type library COMPlusServer2003 was exported from a CLR assembly and can not be re-imported as a CLR assembly." I tried to add reference from just .NET tab or browsing the dll. It works with locally, but doesn't work with remotely. I've searched any source code or help over web. I've found only about how to make COM+. I couldn't find how to create client calling the .net COM+ remotely. Here is the code, using System; using System.EnterpriseServices; namespace COMPlusServer2003 { [Transaction(TransactionOption.Required)] [ObjectPooling(Enabled=true, MinPoolSize=4, MaxPoolSize=4)] public class Bank : System.EnterpriseServices.ServicedComponent { public Bank() { } [AutoComplete] public int Add(int i1, int i2) { return i1 + i2; } } } AssemblyInfo is [assembly: AssemblyDelaySign(false)] [assembly: AssemblyKeyFile("..\\..\\COMPlusServer2003.snk")] [assembly: AssemblyKeyName("")] [assembly: ApplicationName("COMPlusServer2003.COMPlusServer2003")] [assembly: ApplicationActivation(ActivationOption.Server)] [assembly: ApplicationAccessControl(false, Authentication=AuthenticationOption.None)] And client app is: //Testing Late binding private void button3_Click(object sender, EventArgs e) { System.Type type = System.Type.GetTypeFromProgID("COMPlusServer2003.Bank", "remoteComputer01", true); object app = System.Activator.CreateInstance(type); object[] args = {1, 2}; object result = type.InvokeMember("Add", System.Reflection.BindingFlags.InvokeMethod, null, app, args); //Method 'System.__ComObject.Add' not found. Exception is thrown MessageBox.Show(result.ToString()); } //Testing Early Binding //On local, my development computer where server COMPlusServer2003.Bank is. It works ok. private void button4_Click(object sender, EventArgs e) { System.Type type = System.Type.GetTypeFromProgID("COMPlusServer2003.Bank", "w2kpro3", true); COMPlusServer2003.Bank app = (COMPlusServer2003.Bank)System.Activator.CreateInstance(type); int result = app.Add(1, 2); MessageBox.Show(result.ToString()); } Early Binding code throws error when the application calls from other machine remotely. I did installed the proxy(created by Exporting it from the server COM+) on the other machine before launching the client. I have no idea! It should work. Please help. I couldn't find any help from any article including msdn.. Any comment will help!

I have to parse javascript codes that are read from .js file. Does anyone know javascript parser that I can use with api it provides? I wrote regularexpressions to parse it. But, it's better to go with existing javascript parser rather than coding myself and debugging hard myself.. :p Thank you..

Sure you need this. You shouldn't miss Regulator, free tool. It provides regular expression search from web, parsing, coding supports, etc. It's best tool you need start with. Get from. http://regex.osherove.com/ and read this link article introducting 10 tools you need with .NET. http://msdn.microsoft.com/msdnmag/issues/04/07/MustHaveTools/default.aspx It makes your life easier as it did to me.

Hi, all I bind DataTable to DataGrid from Page_Load event. DataView dvw = ds.Tables[0].DefaultView; this.dgColorDate.DataSource = dvw; this.dgColorDate.DataBind(); And I want to hide certain column and add some control to cell. When I try to do it from PreRender event handler. this.dgColorDate.Columns[(int)Lst.MDL_MFG_COLOR_ID].Visible = false; this.dgColorDate.Columns[(int)Lst.Colors].HeaderText = "Colors"; It throws error. When I check it in debug mode, dgColorDate.Column.Count returns 0. How can I solve this?
