 - IDisposable.Dispose, Object.Finalize and threads IDisposable.Dispose is documented as the method where you have to release unmanaged resources. Dispose is called by Finalize. Finalize is called by garbage collector after the object becomes inaccessible. The documentation says: "The thread on which the finalizer is run is unspecified". So the question is: My object has allocated a [win32] window handle using CreateWindow (called using P/Invoke) and has to destroy it. But Win32 SDK say that DestroyWindow has to be called from the same thread that called CreateWindow. This seems impossible given Dispose/Finalize/GC patern. Any advice ? btw: Let me know if I should post to another group. -- francois.piette@overbyte.be The author for the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be Tag: Software and Hardware Inventory Tag: 74373

 - question about paging in Datagrid question about paging in Datagrid. i would like to ask, normally, we bind the datagrid with DataSet if a query like "select * from item" contains 1000000 records, it seems that getting all the records and load it in the memory(DataSet) is a resource-consuming task. (please correct me if i say something wrong) So, i was planning to connect to database and fetch 10 items each time, when page is changed, connect to database again and fetch next 10 items. Is my planning a good way to save the resources? or Paging in datagrid has done something to save the resource? Tag: Software and Hardware Inventory Tag: 74372

 - Using Help remotely Hi, I have a client program that is one touch installed and hosted on an IIS server. My question is, what is the best way to provide user interface help to the client program. Two ideas have come to mind. 1) - Let the client program download the .chm and reference it locally. This is probably a pain. 2) - Let the client do remote calls to the server to request the help and the server then returns the requested help info. Not really sure exactly how I would make that work. Since I am not sure that either of these ideas is really workable, there must be a third and correct way. Would someone please enlighten me as to what it is? Thanks ------------------------------------------- Roy Chastain KMSystems, Inc. Tag: Software and Hardware Inventory Tag: 74370

 - How to cancel a pending BeginReceive ? What is the proper way to cancel a pending BeginReceive/EndReceive ? Can it be done without generating an exception ? Currently I shutdown and close the socket. The blocking "EndReceive" throws System.ObjectDisposedException. I try to avoid throwing exceptions when ever possible, and reserve them for unanticipated problems. Trying to stop a background read/process loop is an anticipated activity. For me the debugger delays 15 seconds when ever an exception is thrown. But regardless, I am hoping for a cleaner approach. I can not find guidance on this issue in framework documentation. Forgive the cross posts. It would be nice to have a specific framework/network related NG. Thanks for any insight - Best regards - Lee Gillie - Spokane, WA Tag: Software and Hardware Inventory Tag: 74367

 - Signing Assemblies Using VS .Net 2003 1. I'm confused on how to remove compile errors below. Not sure if I need/how to use Al.exe and Gacutil.exe tools with VS, etc. 2. My company doesn't have a private key and the local windows application I'm creating is for internal company network use only. Should I create a public key? 3. My goal is to compile a Release version of the application to the network and then use caspol tool to trust assembly. Make Sense? Steps: (a) Created key pair (sn -k foo.snk) and copied foo.snk to C# project \obj directory (is my next step: sn -p foo.snk fooPub.snk & AssemblyDelaySign(true) & AssemblyKeyFile (fooPub.snk) ???)

 - HELP-Sorted Datagrids and modal dialogs I have been on newsgroup for week. I have seen anything that will help me. Basically, I have a form with a datagrid that can be sorted or unsorted (it is up to the user). Then, I display the data of the selected row in textboxes on dialog that execute by the user press a button. The following code works if I do not sort the datagrid before I press the button to bring up the dialog. It is when I sort it the datagrid I have the issue private void Frm_CustomerAU_Load(object sender, System.EventArgs e Frm_Customers frmCustomers= (Frm_Customers) this.Owner; CurrencyManager currencyMgr = (CurrencyManager)this.BindingContext[frmCustomers.tableInfoDG.DataSource, "Table"] currencyMgr.Position = frmCustomers.tableInfoDG.CurrentRowIndex DataRow currentRow = ((DataRowView)currencyMgr.Current).Row txtBxCompanyName.Text= currentRow["CompanyName"].ToString() I have also tried using the following code to bind the table to the textbox and I get the same result txtBxCompanyName.DataBindings.Add("Text", frmCustomers.tableInfoDG.DataSource, "Table.CompanyName") I believe it has something to do what I am setting CurrencyManager position to ( currencyMgr.Position = frmCustomers.tableInfoDG.CurrentRowIndex;). I know I need it to be the position of the underlying table in order to get the selected position in the datagrid. I just do not know how to get the position. By the way, this is C Any help would be greatly appreciated Tag: Software and Hardware Inventory Tag: 74362

 - Changing reference from 1.0 framework dll's to 1.1 framework dll Hello, I am developing an application using ASP.NET and ORACLE. Initially I loaded Visula studio . NET 1.0 framework and later updated it Framework 1.1 . So, now, I got two different directories "WINNT\Microsoft.NET\Framework\v1.0.3705" and "WINNT\Microsoft.NET\Framework\v1.1.4322", in my system holding dll's. At present, this application is referencing to 1.0 Frameworks dlls (e.g. system.dll,system.data.dll etc). But, now I want to change this reference to access dl's from 1.1 framework so that I can use other useful methods and features. For this, When I removed the reference of existing dll and then tried to add NEW reference of dll's from 1.1 framework directory, I am getting MANY compilation error. Could any one help me to resolve this problem? My goal is to change the reference of dll's to access 1.1 framework's dll instead of 1.0.

 - Problem with WebProxy class I recently encountered a problem with the following piece of code in an ASP.NET application that has been running successfully for a couple of months. It requests a web-page from an external web-site, using our corporate proxy. Our company has two proxy servers with the same DNS name. If you execute the nslookup command (at the Windows command prompt), two IP addresses are returned. When one of the proxy server crashes (as it did the other day), Internet Explorer continues to work correctly. However my code failed until the dead proxy server was fixed. It seemed to cache the IP address of the failed proxy server and continue to try and use that machine rather than switching to the live machine. Is there anything I can do to stop this behaviour? Here is the code: HttpWebRequest hwrRequest = (HttpWebRequest)WebRequest.Create( IntranetConfiguration.ExternalSystemConnectionStrings[sExternalSystemKey]); hwrRequest.Timeout = REQUEST_TIMEOUT; //Set up proxy information hwrRequest.Proxy = new WebProxy( IntranetConfiguration.Proxy.Address, IntranetConfiguration.Proxy.Port); hwrRequest.Proxy.Credentials = new NetworkCredential( IntranetConfiguration.Proxy.Username, IntranetConfiguration.Proxy.Password); //Go and get text response from Shareprice service HttpWebResponse hwrResponse = (HttpWebResponse)hwrRequest.GetResponse(); Stream strResponse = hwrResponse.GetResponseStream(); StreamReader srResponse = new StreamReader(strResponse); sHtmlText = srResponse.ReadToEnd(); Tag: Software and Hardware Inventory Tag: 74328

 - Memory/Leak Tool? I have a Windows app (it will be promoted to a Service once this problem is sorted out) that cyclically, every minute, connects to five SQL Servers over the WAN, extract data and insert the data in a local SQL Server, using the OLEDB provider. Every cycle I create one local connection and five remote connections, do the stuff, close the connections and dispose everything that has a Dispose method (OleDbConnection, OleDbDataAdapter and OleDbCommand). After running overnight the performance degrades and if I examine the Private Bytes of the process (using Performance Monitor, the way we looked for memory leaks before DOTNET in C++, but should still be valid), it goes up from approx. 1.3 MB to over 2 MB. I've been using DOTNET from the first Beta and never thought I'd say this, but I suspect a leak. Is there a method/tool that will show me the type of DOTNET objects being leaked, or give me some indication of where to look for the problem? Thanks. Tag: Software and Hardware Inventory Tag: 74302

 - Thread question Child threads aren't allowed to touch main thread objects. The session object in ASP.NET belongs to the main thread. The way around this is to pass in a reference in the thread constructor so that the child thread can use the object safely since there is no control.invoke available like in winforms. Why does this work? This has been bugging for a while. So the class would look something like this: public class test { public test(HttpContext currObject);..... and the call would be test t = new (HttpContext.Current); Technically, I can't see what is happening behind the scenes to force thread safety.

 - string, GetHashCode, and uniqueness hi all, msdn says: "the implementation of GetHashCode provided by the String class returns unique hash codes for unique string values." source: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemobjectclassgethashcodetopic.asp sure, hashes must try to yield good distribution but how could uniqueness be guarranteed in this case? is it best effort? is it under certain conditions? GetHashCode returns an int and so it is limited to a 32-bit number. that's a big number but there are infinite varieties of strings. just imagine a, aa, aaa, aaaa, aaaaa, ad infinitum. and that's just using the letter 'a'. thanks in advance for clarification, rh Tag: Software and Hardware Inventory Tag: 74286

 - How to stop users from clicking buttons more than once? I have a C# asp.net page that when you click a button, it writes a record (based on entered values) to the database. I've found that if you click the button multiple times quickly, multiple records are written. What is the best way to deal with this? The page takes a few seconds to process after the button is clicked so it doesn't reach the point to be reloaded with the button disabled. I tried disabling it with Javascript, but then the server side events didn't fire. I tried setting a session variable as soon as the button was clicked and only running the code if the variable was not set, but that didn't work either. What is the best way to do this?

 - wsdl.exe and Nillable Value Types I am attempting to use wsdl.exe to generate a Web Service Client in C# from a valid WSDL file generated by Apache Axis. My application requires the ability to distinguish between an unspecified value and a specified value. For that reason, the WSDL that is generated by Apache Axis utilizes 'nillable="true"' to permit Web Services Clients to indicate a value or specify 'nil'. The problem I am having with .NET and wsdl.exe (that I did not have with Apache Axis and Java Web Services Developer Pack) is with Value Types. Here is a portion of the WSDL presenting a problem: <complexType abstract="true" name="Type"> <sequence> <element name="localId" nillable="true" type="xsd:string"/> <element name="id" minOccurs="0" maxOccurs="1" nillable="true" type="xsd:int"/> </sequence> </complexType> When wsdl.exe generates its class from this, it creates the following: public abstract class Type { public string localId; public int id; } The problem is that the "int" is a Value Type that is incapable of storing null. I have tried the following all to no avail: 1. Replacing 'type="xsd:int"' with 'type="soapenc:int' (which made Java WSDP work) 2. Including/Removing 'minOccurs' and/or 'maxOccurs' 3. Manually replacing 'public int id' with 'public SqlInt id' (SqlInt is not the correct name, but its the one from the SQL namespace that is used to support nulls for ints in the DB ... .NET barked at me when I attempted to use this telling me it can't be used for XML serialization or some such thing). I am out of ideas and wondering if you can guide me to a way to AVOID having .NET pass a zero(0) when this attribute is not specified (which is what it currently does for Value Types). I was hoping to find the equivalent of java.lang.Integer (which can be null) in C# but have had no success. One last note: This WSDL will be consumed by clients who purchase the software I am developing. They will be responsible for generating their own Web Service Clients using the toolkit of their choice, so I am trying to make it as standardized as possible while requiring minimum client intervention/recoding when they generate the Web Service client. Thanks in advance for any suggestions. Erik Tag: Software and Hardware Inventory Tag: 74282

 - wsdl.exe and Two-Dimensional Arrays I am attempting to use wsdl.exe to generate a Web Service Client in C# from a valid WSDL file generated by Apache Axis. There appear to be a problem recognizing a 2-Dimensional Array that did not present a problem for the Apache Axis Toolkit or Java Web Services Developer Pack Toolkit when they generated the client code. "GridField" represents a 2-Dimensional Array of "Field". Here is a snippet from the WSDL describing it. <complexType name="GridField"> <complexContent> <extension base="tns4:Field"> <sequence> <element name="fields" nillable="true" type="impl:ArrayOfArrayOf_tns4_Field"/> </sequence> </extension> </complexContent> </complexType> <complexType name="ArrayOfArrayOf_tns4_Field"> <complexContent> <restriction base="soapenc:Array"> <attribute ref="soapenc:arrayType" wsdl:arrayType="tns4:Field[][]"/> </restriction> </complexContent> </complexType> <complexType abstract="true" name="Field"> <sequence> <element name="name" nillable="true" type="xsd:string"/> <element name="metaData" nillable="true" type="tns5:MetaData"/> </sequence> </complexType> When wsdl.exe creates the Web Service Client code in C#, it generates the following: [System.Xml.Serialization.SoapTypeAttribute("GridField", "urn:fields.axis.webservices.sparta.com")] public class GridField : Field { public Field[] fields; // Note: Only 1 Dimensional Array } I then go in and modify it to be "Field[][]" and all works fine.

 - Delegate and Thread Problem I have a Delegate based Project that contain classes whose purpose is to instantiate objects of another Project (or Library) using Delegates. I have a client application that uses this Delegate based project to call library method asynchronously. Delegate based project returns the control to the client immediately and so the client can perorm other tasks. Every thing works fine but soon as i close the client application, the back ground processing also ends. In other words, the Delegate based project and library Project also stops. why is that? How can i call method using delegate that continue the processing even if the client application terminates. I can work around this scenario by creating threads and calling method in thread. My client application calls the method of a project named ThreadCreator. The ThreadCreator in turn creates a new thread and calls the appropriate library method in that thread. Now even if the client application terminates, my processing continues. The problem with this approach is that my ThreadCreator project cant call method that takes parameters. The work aournd here is to go for statefull object, but my library objects are all stateless. How can i call method using thread that takes parameters ? Please answer for both scenario Regards, Irfan Tag: Software and Hardware Inventory Tag: 74273

 - Typecasting problem Greeting, We have a component featuring "late/dynamic-binding". Its being used by 2 app, with only the 2nd giving a weired problem. ... objAssembly = Assembly.LoadFrom(strAssemblySource); objInterface = (InterfaceX) m_objAssembly.CreateInstance(strClassName); ... It worked well for 1 app, but at 2nd app, the objInterface always a "null", and no error, until its method being executed. objAssembly - is a (supposed) GAC stuff, as well as the objInterface. they show up in the GAC list as expected. The only way so far I can workaround this is by placing the interface assembly within the 2nd app bin folder. But such is not the case for 1st app. I debugged all checked: - the (windows) identify used to invoke this component is identical. - shouldn't be security issue, as the same also being applied for 1st app. the apps are asp.net wep app, all developed with c#. Can anyone help in this one? Tag: Software and Hardware Inventory Tag: 74234

 - Thead APIs So the .NET Thread class has a name property but the ProcessThread class does not. And the ProcessThread class has an id property but the .NET Thread class does not. That's just strange. You can get the thread id from AppDomain.GetCurrentThreadId() but it seems logical that it would be accessible through the Thread class. I created a bare-bones Console C# app. and listed the process threads using GetCurrentProcess().Threads. There were like 5 or 7 threads created! What are all those threads for?

 - Testing for a type at runtime. I have been testing for a type using code like if(obj is MyType) . . . do somethin Now I want to test for MyType as a return from a metho Type ReplyType( return typeof(MyTYpe) . . . if(obj is this.RepyType() . . . do somethin The problem is that the 'is' operator complains that it is expecting 'Type'. The return value for RelyType() is Type so I am not sure what it is complaining about or how to fix it. Any ideas? Thank you for your help. As a bonus I would also like to use the 'as' operator and call a constructor given a type. But I probably can figure out how to do those functions once I have the above figured out Thanks again Kevi Tag: Software and Hardware Inventory Tag: 74227

 - deserialization problem hi, i have a problem deserializing an object. that object is an arraylist wich has customized classes stored. these classes(dlls) are stored in a subfolder of the mainprogram. serialization is ok, but when i try to deserilize it, the program is not able to locate the dll. my question is, how do i provide information to the formater (that i am using to deserialize the class) about the location of the dll that is needed for the deserialization? thanks in advance, Dante Tag: Software and Hardware Inventory Tag: 74224

 - GetProcesses() hang I have a real simple C# console project, consisting of this: using System.Diagnostics; static void Main(string[] args) { Process[] processes = Process.GetProcesses(); // write all of the process info foreach(Process p in processes) Console.WriteLine(p.ProcessName + " : " + p.MainWindowTitle); Console.ReadLine(); } When I run it on my dev machine it hangs on the call to Process.GetProcesses(). Task Manager shows 0% CPU and a steady 10,964 mem usage while it's hung. There are 40 tasks running, including devenv, newsreader, Norton Internet Security, etc. When I run this little test on other computers (most have more tasks running), GetProcesses() returns almost immediately and all processes are listed. On my dev machine this console project has been running for the past hour, and it still hasn't returned from GetProcesses(). I'm administrator on all tested systems.

 - .resource File I use a .resource file to save some name-value inforamtion. I use resource manager class to create the resource file and read out information when the system starts. The problem I met is: when I distribute the system to user, they read the information out without any problem, but when they try to write new name-value to the resource file. They met problem: .resouce file was used by another process, and can not create a new one. Or the access to the file is denied. This problem only happen sometimes. Delete the file is a way to fix it. However, if the file is part of distribution set, it can not be deleted. Anyone meets the problem? Any suggestion is appreciated. Ying Tag: Software and Hardware Inventory Tag: 74215

Hi,

There are some good extensive samples or components that make software and hardware inventory with WMI easy

I'm seeking some examples or WMI class/property listing to catch the components in the machine that mades up a good software/hardware inventory.

Hi,

Add a reference to system.management.dll

Private Sub GetDevices()
Dim moReturn As Management.ManagementObjectCollection
Dim moSearch As Management.ManagementObjectSearcher
Dim mo As Management.ManagementObject

moSearch = New Management.ManagementObjectSearcher("Select * from
Win32_PnPEntity")

moReturn = moSearch.Get
For Each mo In moReturn
Dim strOut As String
strOut = String.Format("{0} - Status {1}", mo("Name").ToString,
mo("Status").ToString)
Trace.WriteLine(strOut)
Next
End Sub

Private Sub GetInstalledSoftware()
Dim moReturn As Management.ManagementObjectCollection
Dim moSearch As Management.ManagementObjectSearcher
Dim mo As Management.ManagementObject

moSearch = New Management.ManagementObjectSearcher("Select * from
Win32_SoftwareFeature")

moReturn = moSearch.Get
For Each mo In moReturn
Dim strOut As String
strOut = String.Format("{0} - {1}", mo("productName").ToString,
mo("Vendor").ToString)
Trace.WriteLine(strOut)
Next
End Sub

Thanks,

Very usefull this sample code. But more one question:

I search the documentation of the ManagementObjectSearcher and didn't saw the complete list of the "tables" that I can select from it. Win32_SoftwareFeature, Win32_PnPEntity ... etc ...

Can you indicate me in what documentation can I find it ?

Thanks
Lucas Ponzo.
