    - 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: Using DSOleFile to read double-byte character file 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.

    - Finding process user identity Hi I am using the System.Diagnostics.Process class to find information about the running process on, lets say win2k. I can get to almost all the information I need from the Process object except the user name that the process is running as. In the Task Manager, I can see the process Image Name, User Name, CPU, etc. Here is the code example of what I am doing Process[] procs = null string processList = "" procs = Process.GetProcesses() for(int i = 0; i <= procs.GetUpperBound(0); i++ Console.WriteLine(procs[i].ProcessName.ToString() + " is still responding!") The question is, how can I get to the User Name for a specific process? Do I have to use Win API to do this Cheers. Tag: Using DSOleFile to read double-byte character file Tag: 74299

    - 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: Using DSOleFile to read double-byte character file 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: Using DSOleFile to read double-byte character file 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. Is there an explanation / workaround for this? Tag: Using DSOleFile to read double-byte character file Tag: 74280

    - 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: Using DSOleFile to read double-byte character file 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#.

    - Timer event pauzes when application is inactive Hello I'm coming across the following problem. I have a application that "pauzes" when the application becomes inactive. The application has a timer and on the Tick event, the timer is being stopped, some functions are being executed, and then the timer is enabled again. This should work properly and it does on my laptop. On a PC of a client it doesn't. When the PC is not in use then the application pauzes, in other words the timer stops ticking. When the mouse is moved or the application get focus (by clicking it) the timer continues like nothing happens The problem is that I cannot reproduce this problem and I cannot debug it, because then the mouse is moved and the application continues. Very frustrating The solution I now have, is to make the process High priority, but in my oppinion not a good solution. It should be working with a Low priority as well Can anybody tell me what's going on Best regards Michiel Doeven Tag: Using DSOleFile to read double-byte character file Tag: 74211

    - Drag and drop from .NET to desktop... Greetings all. I have a c# application that shows documents residing in a repository on a server (TCP, not file-sharing). Users can browse the documents and they should be able to select one or more and drag them to the desktop. We had an old, old vb5 (or vb6) version of the app that worked ok. There was a callback in vb-land called ProvideData or some such that was the hook we could use to blast the data to the receiver once the drop was completed. Has anyone any code that shows how to do this in C#? I know that there are lots (and lots) of corners that are not .NET-ified, but this application without drag and drop would be totally lame. I can't download the file locally and then drag it (which does work) as they are really big, typically 1-10 meg. Does anyone have a pointer to help me out? Commercial software would be fine too. Thanks! Joe Tag: Using DSOleFile to read double-byte character file Tag: 74209

    - Forms, threads, and BeginInvoke Can someone explain this to me. I have a function that is called asynchronously using a delegate, which has a callback function. In the callback function, I want to create a new form. However, the call to BeginInvoke on the delegate creates a new thread which the form is attached to. This causes the form to not receive any events because there is no messsage loop set up on that thread. Of course, I COULD do Application.Run for this new form, but I don't WANT to do that. I would LIKE the form to run in the same thread as the thread that called the async method. Now, my question is, how can I have the same behaviour as the File IO Stream classes? They have methods called BeginRead which takes an async callback, but this does NOT create a new thread. If I use the line commented out (System.IO.File.OpenRead...etc) below, then the form gets created in the main threads context and everything works fine. So...does anyone know how the Stream IO classes are able to do this? I've checked the documentation, but I've only seen them talking about BeginInvoke. Is there another way? I'm aware of Control.Invoke, but I don't want to have to have a reference to a control. BeginRead doesn't seem to need this. How do they do it? public delegate void someCallBack(); void callback(IAsyncResult ar) { new Form1().Show(); } void dosomething() { //do something... } private void button1_Click(object sender, System.EventArgs e) { //The line below WORKS! //System.IO.File.OpenRead("C:\\somefile").BeginRead(new byte[100],1,0,new AsyncCallback(callback),null); someCallBack scb = new someCallBack(dosomething); //this line does NOT work scb.BeginInvoke(new AsyncCallback(callback),null); } Tag: Using DSOleFile to read double-byte character file Tag: 74203

    - Differences in Framework 1.0 & 1.1 Is anyone aware of differences in Framework 1.0 and 1.1 in the XmlValidatingReader class Specifically in the way the Validation Event fires I'm trying to validate an xml document in several parts so I broke my schemas apart. The first schema defines three high level nodes and the others define the detail elements of these three nodes. After instantiating an XmlValidatingReader class I loaded the first schema into the Schemas collection of the XmlValidatingReader and performed the ReadOuterXml method In the 1.0 framework the event only fired when there was a problem with one of the three high level nodes In the 1.1 framework all of the detail nodes within the xml document receive an error indicating that they were not declared I've just upgraded this project from 1.0 to 1.1 so I'm trying to determine if this functionality changed Thanks Tag: Using DSOleFile to read double-byte character file Tag: 74194

    - marshalling : C# string to C++ CString Hi group I have a C++ dll containing the following functions : extern APIENTRY WINAPI void F1(CString str1,CString str2) { F2(str1,str2); } /*intern*/ void F2(CString str1,CString str2) { //do stuffs ..; } I have this C# code : [DllImport("my.dll", EntryPoint = "F1")] public static extern bool csFct(string s1 ,string s2); When i call to csFct passing two string in parameter, I get the call of F1 correctly in the DLL, but it bug when calling F2. I suppose it is due to marshalling poblems, but i am newbie to that, so please help :) how can i convert internally my strings to CStrings inside the F1 fonction, where they are allready CStrings... ? it is confusing for me. thank you for help.

    - Why use attributes? Hi I have a very basic question here - why do we need attributes or basically how we decide when to use attributes? I have used a lot of .net inbuilt attributes, but have not been really able to put this great feature to use by defining custom attributes. I know how to use them but the bigger question is when should we use them. Perhaps this might be a very simple question to the .net world. All help is welcome.

    - DrawString Hi, Trying to figure something out with Font widths, Measure String, and DrawString. In the OnPaint event I have something like this. e.Graphics.DrawString("Testing 123", this.Font, Brushes.Blue,0,0); e.Graphics.DrawString("Testing ", this.Font, Brushes.Red, 0, this.Font.Height * 2); float lw = e.Graphics.MeasureString("Testing ", this.Font, 5000, new StringFormat(StringFormatFlags.MeasureTrailingSpaces)).Width; e.Graphics.DrawString("123", this.Font, Brushes.Green, lw, this.Font.Height * 2); Ok, Everythign works fine but the 123 on the second line doesnt start where the 123 on the first line does, it starts to far to the right. (NOT SURE IF THE FORMATTIGN WILL MESS UP) e.g. Testing 123 Testing 123 Questions. 1) What's going on here? :) 2) I noticed that DrawString doesnt start drawing on the left most pixel when setting float x to 0 in drawstring function, why is this?

Hi,

I am using DSOleFile to access double-byte character file property
information but it does not seem to retrieve the information correctly. Can
someone tell me how to use the DSOleFile.exe to access double-type character
file property information?

Thanks in advance.
