Hi there I am developing an application where in I need to launch a "Client exe" (.NET Winform app) from a Web page (which could be either in an Intranet/Intranet application). I am able to successfully launch the executable using javascript, using the following code ...... function OpenExe( { var os = new ActiveXObject("WScript.Shell") var params = "C:\Test.exe param1 param2" var s = os.Run(params) return But to achive the following I need to Manually enable the IE security setting â??Initialize and script ActiveX controls not marked as safeâ?? in the respective zone.

    - Rollback transaction doesnt work when DataAdapter.Update() throws exception caused by RAISEERROR in a trigger Hi, I have a trigger like this (simplified to illustrate the problem): -------- CREATE TRIGGER Test ON [dbo].[TestTable] FOR INSERT, UPDATE, DELETE AS RAISERROR( 'test trigger error !', 16, 1) --------- And a C# code portion: (new record inserted in dsFormTest.TestTable) --------- OdbcTransaction odbcTrans = null; try { if ( odbcConn.State != ConnectionState.Open ) odbcConn.Open(); odbcTrans = odbcConn.BeginTransaction(); odaTest.InsertCommand.Transaction = odbcTrans; odaTest.Update( dsFormTest.TestTable ); odbcTrans.Commit(); } catch( Exception xc ) { if ( odbcTrans != null ) odbcTrans.Rollback(); MessageBox.Show( xc.ToString() ); } odbcConn.Close(); ---------- BUT, instead of rolling back transaction, the odbcTrans.Rollback() throws new exception with message: System.InvalidOperationException: RollbackTransaction requires an open and available Connection. The connection's current state is Open, Fetching. any clues why? Tag: Strong Name for VB COM dll Tag: 70684

    - .Net Codepage 850 problem with uppercase accented characters Hi. I have a problem using ASP.Net or VB.Net (Winforms) accessing an Oracle database that uses WE8PC850 (which is the IBM-PC codepage 850) character set. Our older ASP apps work fine with this database, but the three different ASP.Net and VB.Net Winforms test apps we have developed so far do not display uppercase French accented A and E characters correctly I have tried all the potential codepages that seem appropriate: IBM850, IBM863, Windows-1252, ISO-8859-x, utf-8, utf-16 and so forth. The closest seems to be IBM850 reponse and request encoding with the response.charset set to Windows-1252, or ISO-8859-1. As all of the ASP apps work fine and display the codepage 850 uppercase accented characters correctly on our three different desktops we have tried so far, it has to be a problem with the .Net managed provider for Oracle / the .Net codepage 850 implementation, as the same Oracle 8.1.7 client software is used for both the ASP and .Net applications on the client Because of this Oracle refuses to look into the matter, gleefully pointing out that it must be a Microsoft problem! : We have tried bland, vanilla test apps in .Net and the problem is always there. None of the older ASP apps (that just use defaults for character sets and codepages etc.) have any problems. All of the desktops have the NLS_LANG parameters set correctly and it DOES seem to be a Microsoft, .Net-specific problem I have tried MSDN and web searches to no avail up to yet. Having wasted two to three days trying different solutions, I am now desperate for "official" assistance from Microsoft. I am working for AMITA Corp (Ottawa, Canada) and they are a Microsoft Solution Provider, so hopefully we can get some support on this, as we are now almost certain that it IS a .Net bug in the IBM850 codepage support in .Net. Any and all help is greatly appreciated. The Oracle DBA's have washed their hands of the matter and are suggesting we forget about .Net and revert to using Oracle whatever's! Of course we do NOT want to accede to that suggestion!!! ; Can anyone from Microsoft (or anywhere else for that matter) help out here Barrie Gray Tag: Strong Name for VB COM dll Tag: 70661

    - Is this a bug in ?: Operator, the addition does not perform as expected I am posting the code snippet here. It seems to me that the ?: Operator is not behaving properly. It seems like it is a bug: TimeSpan ts1, ts2; float dayHours = 0; ts1 = (some_datetime_variable_1); ts2 = (some_datetime_variable_2); // ****************** Working Code ************************* // This computes dayHours correctly if(ts1.TotalHours > 0) dayHours = (float)ts1.TotalHours; if(ts2.TotalHours > 0) dayHours += (float)ts2.TotalHours; // ****************** Working Code ************************* // ****************** Non-Working Code ************************* // This does not add the portion after + sign dayHours = (float)(ts1.TotalHours > 0 ? ts1.TotalHours : 0 + ts2.TotalHours > 0 ? ts2.TotalHours : 0); // ****************** Non-Working Code ************************* As commented above, I am trying to condense the working code to one line using ? operator but the one line non-working code dows not add the variable after + sign. For example, if ts1.TotalHours is 4 and ts2.TotalHours is 3, the dayHours is computed as 4. Though, I can use the working code, which takes four lines but it is something I am doing wrong here or it is a bug in .NET Framework?

    - Attribute Construction/Validation, How? Hi, I am trying to writing my own custom attribute classes and would like to have the same level of functionality as some of the attribute classes that ship with the .NET Framework. Specifically I would like to be able to take action with my attribute at compile time. For example, the Guid Atribute will give you this error at compile time if you attempt to using it with an improperly formatted string: [Guid("garbage string")] public class Test { } Yields the compiler error: 'Incorrect uuid format.' Another example of attributes taking action at compile time is the ComImportAttribute. Attempting to use this attribute by itself causes the following to happen: [ComImport] public class AnotherTest { } Yields the following two compiler errors: 'The Guid attribute must be specified with the ComImport attribute' 'A class with the ComImport attribute cannot have a user-defined constructor' I would really like to have this kind of flexibility with my own custom attributes. Is this at all possible? I sadly suspect the answer is no. As a matter of fact, it seems as if user defined attributes can only be accessed (and only invoked once reflected) at runtime. If this is not the case, could someone explain how it is possible to take action with user defined attribute at compile time, and even load time? Thanks in advance.

    - trying to get user properties from Active Directory Hi all, I have a good background in vbscript and know fairly well how to read and write active directory with it. I just passed now to vb.net and the gap is quiete impressive.... What I find most diffucult, however, is the declaration of the variables. In vbscript these do not need to be declared or specified the type. Now, what I need to do is to bind a computer and read the "userSharedFolderOther" attribute. I have a simple vbscript which does the job but my vb.net cannot read this property. I believe the problem might be in the variable not been declared correctly. I simply declared it as "Dim My var". I guess I should add something like "as ...." but I don't know the type of variable...is it string ???? I can read other attributes fine, but not this one.... However, this is the code...(only the interesting part)... Dim pcPrinter Searcher.PropertiesToLoad.Add("userSharedFolderOther") pcPrinter = (Computer.Properties("userSharedFolderOther").Item(0)) If IsArray(pcPrinter) Then For Each Printer In pcPrinter MsgBox(Printer) Next Else MsgBox(Printer) End If Error: Specified argument was out of the range of valid values. vb.net Says the guilty line is the one that starts with pcPrinter... Can you help me out pls ? Thanks in advance !!!!! Bar Tag: Strong Name for VB COM dll Tag: 70623

    - Component dependencies, BeginInit() and Endinit() Component A has a reference to Component B. Both implement ISupportInitialize. In Component A's EndInit() routine, its initialization has been finished so it triggers an even which Component B will handle.

    - StartPosition.CenterParent Hi Guys and Gals, I have a small, two form, application. Form1 is the main window and Form2 is a small window that has a label and a progress bar on it. I wish to display form2 whilst doing some processing in Form1 and update Form2 as the processing is being completed. I have the update functionality working properly, what I can't seem to get working is the functionality of being able to position Form2 in the centre of Form1. I have set the StartPosition property to CenterParent, but I can't seem to find a property where I can set the parent property of Form2. Forms do have a Parent property, unfortunately it's read only. I can get the form to behave, more or less, correctly if I use ShowDialog instead of Show but that holds up processing whilst the form waits to receive input it can pass back to the main form, which of course is not ever going to come, as the form has no inputs of any kind. The application is not an MDI application so I can't use the MDIParent property. I would also like to stop the form from being moved. Anyone know what property or properties need to be set to make this happen? And I'd like to turn off it's titlebar if possible. Thanks Regards Greg Tag: Strong Name for VB COM dll Tag: 70605

    - xml.xmldocument.load does it load document to memory? I am making a simple app that groups files together by storing them into an xml document. But here is my concern. The xml file that is being loaded could be a gigabyte in size or it could just be 100k.

    - Dynamic Properties, App.config, and <AppName>.exe.config I am having trouble understanding the relationship between Dynamic Properties, the App.config file, and the bin\<AppName>.exe.config file. When I create dynamic properties from the IDE, the forms designer inserts xml nodes in the app.config file and inserts code to read values from those nodes (via a call to configurationAppSettings.GetValue()) on the form where the dynamic properties were set up. When I execute the application, the app.config file is copied as the bin\<AppName>.exe.config file. I am surprised to find the IDE, which automatically generates code to read the dynamic properties, does not generate similar code to write those dynamic properties back. Unless I am missing something obvious, this task is left to entirely user. Note that under the IDE, the IDE generated call to configurationAppSettings.GetValue() is reading from the app.config file. I have found a couple of complete subroutines which write values back, but they all write to the bin\<AppName>.exe.config file. Obviously, since under the IDE values are manually written to the bin\<AppName>.exe.config, they will never be read via configurationAppSettings.GetValue(). So here's the question: Should I replace the IDE generated dynamic properties read code with code to read from the bin\<AppName>.exe.config file? Or should I change the code I stole (from much smarter programmers than I) and write to the app.config file instead? Thanks for any help! Doug Tag: Strong Name for VB COM dll Tag: 70568

    - Link XML file to a datagrid Hi there, I wonder if anyone can give me some help here? I am a newbie at csharp, and am translating a C++ app that I wrote into csharp. What I have is a and XmlDocument in memory, referenced by a variable m_loadedFile = new XmlDocument(); This is then loaded from an Xml file, whose structure looks something like this (for brevity, I know this isnt fully formed!) :- <top_level> <something_0> <level_1> <level_2> <field_1>data 1</field_1> <field_2>data 2</field_2> <field_3></field_3> <field_4></field_4> <field_5>data 5</field_5> <field_6>data 6</field_6> <field_7>data 7</field_7> </level_2> </level_1> <level_1> <level_2> <field_1>data 1</field_1> <field_2>data 2</field_2> <field_3></field_3> <field_4></field_4> <field_5>data 5</field_5> <field_6>data 6</field_6> <field_7>data 7</field_7> </level_2> </level_1> <something_0> <something_1> </something_1> <something_2> </something_3> </top_level> What I would like to do is link the level_1 data as rows in a datagrid, with the field data becoming the cells in the datagrid. When I save the datagrid, I woudl like the level_1 data updated ( I will then save the Xml document at a later point) I think that I have to setup datasets and the like, but after looking at various sites such as codeguru, csharphelp etc, I am really confused! So any help woudl really be appreciated. Thanks in advance Hugh Tag: Strong Name for VB COM dll Tag: 70556

    - DataGrid with checkboxes I need to use the DataGrid control to display rows from a SQL table and also show a checkbox that the user can click on to select different rows. I add a Boolean DataColumn to the table and then assign it to the datagrid. I can click on the checkbox and change the value, but when I click on another row it errors out with that the column is read-only and asks if I want to correct it. It won't let me change the value. If I use the SQL statement to add the column as a constant of datatype 'bit' and a value of -1 then it errors out with an invalid typecast error. Here is the code where I create a new Boolean DataColumn and add it to the table. This should be standard stuff, but I can't get anything to work. Any suggestions? ------------------------------ SQL = "SELECT * FROM tblAnimalFacility"; DataColumn dc = new DataColumn("PrintCard", System.Type.GetType("System.Boolean"),"-1"); ds = Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteDataset(CommandType.Text,S QL); ds.Tables[0].Columns.Add(dc); grdPurchases.DataSource = ds.Tables[0]; Tag: Strong Name for VB COM dll Tag: 70552

    - StateServer and aspnet_wp.exe recycling I have recently converted a site to using the ASP.NET StateServer, and in order to ensure that my changes were successful I made sure I had data in session, and set the idleTimeout value in the processModel section of machine.config to 5 minutes. The aspnet_wp.exe worker process recycled after 5 minutes of idle time as expected, and sure enough the site kept running and I still had access to all my session data. The problem is that after the worker process recycled, when I do anything on the page (eg. just clicking an anchor) it takes 60 seconds for the site to 'reattach' itself (I'm assuming to the StateServer) before continuing on it's merry way. I performed the test several times and each time it took exactly 60 seconds to continue on after the wroker process recycled. The good news is that at least the site stayed up and it can continue to be used, but I'm concerned that if the worker process recycles for any reason, or for any reason the AppDomain is torn down (and trust me there's plenty of reasons why that might happen) then the users will experience this kind of delay. I knwo in the grand scheme of things a minute is not very long, but the perception of users of the site is important. Does anyone know what is actually happening after the worker process is recycled and the next request to the site is made ? Is there a setting somewhere that controls how long the process takes ?

    - String.Join vs. StringBuilder, which is faster? I have a function that takes in a list of IDs (hundreds) as input parameter and needs to pass the data to another step as a comma delimited string. The source can easily create this list of IDs in a comma-delimited string or string array. I don't want it to be a string because I want to overload this function, and it's sister already uses a string input parameter. Now if I define the function to take in a string array, it solves my overload issue, but then I have to convert the array inside the function to a comma delimited string using string.Join(). Alternatively, I can define the input parameter as a StringBuilder (which just contains the comma delimited string), and then do a sb.ToString() to get the string. Which would be a better solution between using string array and then join vs. StringBuilder and ToString? I know if I don't overload at all, it would make the best sense from a performance perspective, but code readability and maintenance become harder as the two functions really do the very similar things.

    - HTTPWebRequest - GetResponse throws exception Hello, I am trying to make a HTTP request to a component on a server. In the past, our client applications have used the XMLHTTPRequest object in MSXML to make the call. See ?OLD CODE'. The call is intercepted by an ISAPI filter which forwards the request to the appropriate application server and then responds. This works fine. For our next generation clients, I wanted to make the call using the HTTPWebRequest or WebClient class provided by .NET. I then would no longer have to rely on an unmanaged COM object and have only .NET assemblies in the applications. That way I could take advantage of the .NET deployment options. The problem I am having is that the function I wrote to make the requests (see NEW CODE) does not work. I can create the request object and write the data to the server, but when I call the following line of code I get an exception (see below). Dim resp As HttpWebResponse = CType(myReq.GetResponse(), HttpWebResponse) Following Exception is thrown, where the WebExcpeption.Status = WebExceptionStatus.ServerProtocolViolation The underlying connection was closed: The server committed an HTTP protocol violation. at System.Net.HttpWebRequest.CheckFinalStatus() at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.Net.HttpWebRequest.GetResponse() at OMNI_Common.MakeCISRequest.MakeWebRequest(String URL, String strRequest, String& strOut) in C:\Projects\OMNI\Frontend\DLL\OMNI_Common\Common Classes\MakeCISRequest.vb:line 258 When I enable logging in my ISAPI filter, I see that the request has been processed and the data is being sent back to the client. The problem seems to be that the client can not process the returned data. I have played with the following many properties and the encoding scheme, but can't seem to get anywhere. Besides the ?The underlying connection was closed' error I have also received the 405 error (Invalid Method). Any feedback would be greatly appreciated. -Peter NEW CODE.

    - Enterprise Templates and Inherited Forms using 1.5 Gig of Memory have an Enterprise Template using a Policy file that I'm experiencing some strange behavior with. I've racked my brain through the news groups and all the examples off of MSDN, but can't seem to locate the what's causing my problem. We are building an enterprise application, with various types of projects Solution BusinessLogic Common DataAccess WinUI - UIBase - UIUser Everything in the templates for the PolicyFiles are working great in all the projects except for my WinUI projects. We are using a BaseForm in the UIBase Assembly that Inherits from System.Windows.Forms.Form. All other UI forms in our application will inherit from BaseForm in the UIBase Assembly. Here we want to put in a policy that all forms must Inherit from our BaseForm. Here's the problem, if I have a policy file associated with my UIUser assembly files and I open a form that inherits from BaseForm in the UIBase assembly, the IDE uses up to 1.6 Gigs of Memory. Not until I close the form is the memory release. I've set the Policy file to be INLUDE all types of components, but I still get the same behavior. If I remove the Policy file from the Project completely, then I don't have the problem at all. Is there a way for me to turn on logging in the IDE to see what is causing the IDE to use some much memory? Do you have any suggestions on what else I can do to get past this problem. Right now this is pretty much a show stopper in regards to using the PolicyFile as developer productivity would be severly reduced.

    - Problem persisting code Hello all; I've written a custom component intended for Windows apps, whose properties are set via a wizard interface. At the end of the wizard, the property values are persisted to code, showing up under the "Windows Form Designer Generated Code" region. Where necessary, I've created TypeConverters and included DesignerSerializationVisibility attributes. This works fine on 3 of my 4 development machines, however on one of the machines a particular property doesn't get persisted. Since this is specific to a single machine, I'm assuming that there must be a problem with that instance of Visual Studio (btw: all machines are using the same versions of VS2003 , Windows2k, and the Framework). We will be uninstalling and reinstalling Studio to see if this cures the problem. Has anyone else encountered anything like this? I'm at a total loss for why this would happen on this machine and not others, especially since they are all the same and updated with service packs and what not regularly. Maybe someone out there has more intimate knowledge of how the Designer generates this code and could shed some light? Thanks in advance, Derrick Tag: Strong Name for VB COM dll Tag: 70503

    - Some questions on what technology to use I am new to Web Services and am trying to get over that feeling of being slightly lost in a foreign place so to speak. I have a few questions: What technology should I be looking at with regards to implementing a web service under dot net? I know this is a pretty open ended question but what I'm looking for is a technology that will see me in good stead for the future whilst being rooted in the *near* future to present. I have had a look at Web Services using remoting and also WSE 2. I'm not currently looking at ASMX as one of my restrictions is that the web service should potentially be independent from a web server like IIS. I get the impression from postings that remoting is probably the wrong way to go as I might have upgrade problems when Indigo comes out; yet it seems the simplest in terms of attaching messages to methods and automatically generating WSDL etc.. Thoughts on this? I have had a look at WSE 2.0 and it seems more difficult to generate a WSDL file (if not impossible) since there isn't such a tight mapping between the message handler and the message structure. Lets say I have a message called Add that takes two parameters and returns the result. From what I have read for WSE I would derive from SoapReciever and override the Receive message manually drilling into the envelopes body using XPath when the message arrived. Another alternative would be to use SoapService which gives me a little extra help by routing the message to a declared method; but the declared method would still be of the form: SoapEnvelope MyMessageHandler( SoapEnvelope message ) { // process message } So I would still have to get down and dirty with some XML. So my question here is if I use either of these ways to handle the message presumably there would be no way of *automatically* generating the WSDL; so I would have to create the WSDL manually, is that correct or am I missing something obvious here? If this is the case will there be (in the future) a more closely coupled link between the message handler and the message format like say: [SoapMessage[urn:math:add]] int Add( int x, int y ) { return x + y; } This would remove the hassle of having to drill into the XML to get my parameters etc. My next stop will be looking at Indigo so how does this fit with where I'm trying to go? Any help/thoughts would be much appreciated... Regards Lee Tag: Strong Name for VB COM dll Tag: 70499

Hi,
I have a VB COM dll (lets name A) which references another VB COM
dll(lets name B).
I created an assembly for A dll named NETA.dll using tlbimp and then I
want to assign it a strong name and sign it and put it in GAC.
I generated key using sn utility named Akeyfile.sn
When I try to strong name it and sign it using VS.NET

[assembly: AssemblyTitle("NETA.dll")]
[assembly: AssemblyDelaySign(false)]
[assembly: AssemblyKeyFile("C:\\Akeyfile.sn")]
it returns me an error that
Assembly generation failed -- Referenced assembly 'NETA.dll' does not
have a strong name.

How am I supposed to strong name it and sign it?
And do I need to give strong name to Vb COM dll 'B' too? If yes then
how will I strong name both of them using VS.NET.?

Run Tlbimp again, this time with the /keyfile option.

Hi,

You can instruct tlbimp.exe to sign the assembly in the first place by
specifying the /keyfile: option in the command line parameters.
