    - Reverse usage of public/private RSA encryption keys for licensing? The way that RSACryptoServiceProvider works is that we encrypt with a public key and decrypt with a private key. This architecture works great for people sending messages to me. However, I now have the opposite application: I want to put a license file on a destination computer and be sure that it remains unaltered. It would be great if I could encrypt it with a private key at our office and transmit the public key and the encrypted file to the destination computer, where anybody can decrypt it and read it, but not change it because we have the private key at our office. I've read posts to "simply reverse the public and private RSA keys" but tried several variations of switching RsaParameters.D, DP, P, DQ, Modulus and others, to no avail. I'm sure that a solution exists, just that I do not know it. How do I, in C# .NET, send a license file to a destination computer, with a public key, anybody can read it, but only we can change it? Thanks. Tag: Multithreading and RollBacks Tag: 87269

    - regex puzzle! The objective is to extract the first n characters of text from an HTML block. I wish to preserve all HTML (links, formatting etc.), and at the same time, extend the size of the block to ensure that all closing tags are recovered. For example, simply extracting the first 400 characters of a HTML block may result in an <i> opening tag being including, but its closing tag being excluding. Or a link may get chopped halfway - [... blah blah <a href="ht] may be the last few characters of the recovered phrase. Ideally, if any html opening tag is included in the first n characters, then any number of extra characters should continue to be extracted from the source block until all paired closing tags are found. We can assume that the source block is well-formed HTML, and every opening tag has a closing tag (whether optional or not). Furthermore (if it makes any difference), we can assume that all tags are given in their simplest forms with no attributes (e.g. <p>, <ul>, <li>, <b>), except for anchor tags, which have the href attribute of course. Can anyone suggest a regular expression to do this? Tag: Multithreading and RollBacks Tag: 87268

    - Windows compound files Are windows compound files supported under .NET? Compound files are like a directory - there are several streams in a single file. I have C++ code for some object classes that use compound files and am having difficulty getting it to compile under .NET because some standard windows header files create compiler errors. Even classes that simply use IStream to read and write themselves will not compile, with errors found in files supplied with Visual Studio. Any suggestions or help would be appreciated.

    - Anyone have info on the dreaded Q316146 bug? ... (i.e. There is no Original data to access) I'm absolutely baffled why Microsoft has decided to give so little information about this issue. We here (as with many other's I'm sure) have wasted countless hours of time finding, researching and redesigning around this issue. I wish someone would clarify Microsofts position on this. For example, it would be nice to know a) Yes we are aware of it, it's fixible and is a high priority b) Yes we are aware of it, but it would require a rewrite of ADO.NET so it's taking a long time but a fix is coming c) Yes we are aware of it, but it will not be fixed until .NET 2.0 d) Yes we are aware of it and it's not being fixed. good luck fools! Now let's analyze what this bug really means. Microsoft has banked it's entire future on .NET (which I might add has been a success so far). With that in mind, most medium to large size applications utilize some form of database and DataSets, DataTables, etc... is the new defacto way in .NET to represent this data in memory. This bug is very easy to get as your application get's more complicated. With this line of thinking, shouldn't this be one of Microsoft's highest priororities!!! -Dave Tag: Multithreading and RollBacks Tag: 87265

    - Framework 1.1 Service Pack 1 Question I am addressing this message to Microsoft directly. Recently this service pack was released, and it has fixed many issues. However, one glaring bug fix, for some reason or another, was left out of this service release. The VersionNotFoundException which will occassionally rear its ugly head when using expression columns in datatables. This bug has been known for a while. For some reason, the release of Framework 1.1 didn't fix it, and yet another opportunity to fix it has come and passed. What is the deal? Does Microsoft not know where the cause of this error is? Is it not a priority? I have a large project which uses expression columns on a rather large scale. The only workaround I have ever seen documented is simply "don't use expression columns." For some of us that is just not an option. Does anyone have a workaround? Will someone at Microsoft please look into this and give us developers some advice as to how to work around this bug? Would that same person give us some kind of time frame as to when this will be fixed. I don't care if VS.2005 fixes it. That is years away from being a development solution for some of us. And would that same person please express our frustration to somebody there at Microsoft so this will get fixed ASAP. Thank you. Tag: Multithreading and RollBacks Tag: 87250

    - aspnet_wp.exe Problem I have performance issues with aspnet_wp.exe. Some time I got the following errors on the production server and hang-up the server until I killed the process. Please advice! aspnet_wp.exe (PID: 3648) stopped unexpectedly. aspnet_wp.exe (PID: 4136) was recycled because it was suspected to be in a deadlocked state. It did not send any responses for pending requests in the last 180 seconds. This timeout may be adjusted using the <processModel responseDeadlockInterval> setting in machine.config. aspnet_wp.exe (PID: 1320) was recycled because memory consumption exceeded the 613 MB (60 percent of available RAM). -- DotNet Guerrilla Tag: Multithreading and RollBacks Tag: 87249

    - Dispose Question Just a quick question on implementing the Dispose pattern. The .NET Framework SDK documentation states that an ObjectDisposedException should be thrown from instance methods (other than Dispose) when resources for the object have already been disposed. This would include any non-shared property procedures as well, right? Seems logical. Just looking for verification. Thanks! Tag: Multithreading and RollBacks Tag: 87238

    - Mistake in MSDN Hello, I think I have found a mistake in MSDN. I have visual Studio 2003 with MSDN. My problem is very simple: I have a webform with a HTML button control as: <INPUT id="Button1" type="button" value="Button" name="Button1" runat="server" onclick="alert('df');"> So its an HTMLServer control which does not submit. I have this code for the button in code behind: private void Button1_ServerClick(object sender, System.EventArgs e) { int h=0; h++; } Now according to MSDN: (Section: ASP.NET Server Control Event Model->Handling a Click Event in Client and Server Code) *********************************************************************** All other HTML controls (those that do not submit a form by default) Include an onclick attribute in the HTML syntax for the control, but follow it with a semicolon (;): <INPUT Type="Button" Runat="Server" Value="caption" onclick="clientfunction();" ...> This causes your function to be called first, before the client-side submit script is called. ************************************************************************* Now in my case, its always the client side script which calls first, no matter what I do, even after using the semi-colon.The control still submits, but first the Javascript fires. So how can we make sure that our server side event is executed first and than the client side script runs (without using RegisterScriptBlock etc). Is the above example a mistake in MSDN??

    - Excel using ado.net - operation must use an updateable query This is driving me nuts. I'm trying to update an Excel spreadsheet using ADO.Net and Oledb in VB.Net. The connection is open, the adapter is connected and the dataset is loaded. Here's the code in question: myDataRow = myDataSet.Tables(0).Rows(RowNum) myDataRow(ColumnCount) = Ailment Adapter.UpdateCommand = New OleDbCommand("UPDATE [" & SheetName & "] SET F" & ColumnCount & " = '" & Ailment & "' where F1 = " & RowNum & "", Conn) Adapter.Update(myDataSet, "[" & SheetName & "]") The query sent is: "UPDATE [Drugs cleaned up$] SET F6 = 'Test Ailment' where F1 = 1" In the spreadsheet, F1 = 1. It's a uniquely numbered column and I assume, the primary key. F6 is also a valid column. The Sheet name is also correct cause it's open. I figured, and am told from MS documents, that a unique column is required to make it an updateable query. That's what I've done but I can't get anything but: "operation must use an updateable query" Every article I find with a solution says it's a permissions issue with ASP.Net. But this is VB.Net, everything running from a machine with Administrator privs. The C drive and the file have Full Access to Everyone and the sheet(s) are not protected. Any ideas? Thanks!

    - Any way to interpret javascript functions? I have an application with a windows form that I am currently embedding an AxWebBrowser object on so that I can have it navigate to a web page. This web page contains simple javascript code which takes two parameters that I pass to it via the URL, and opens a new window with varying characteristics (eg size, toolbar visibility, etc) depending on the data that I pass it. However, the AxWebBrowser places an enormous load on the memory - its footprint runs about 8Meg I think. I'd like to be able to just read the javascript that is returned by the (ASP) web page and let it do its thing directly. Any suggestions on how I can parse the javascript to allow it to work without having to write a javascript parser? Alternatively, any better way to include a slimmed-down browser?? Thanks! -mdb Tag: Multithreading and RollBacks Tag: 87115

    - Synchronize mthd I'm trying to figure out how to implement a static Synchronized() method (like those supported in many of the classes in the Collections namespace). I'm deriving from CollectionBase for a strongly typed collection. I think I understand how to use the SyncRoot property to safeguard operations: lock(this.SyncRoot) { // do the operation... add or remove or whatever } When I run Object.ReferenceEquals(o1, o2) //where o1 = new ArrayList(); // and 02 = ArrayList.Synchronized(o1); I get false. So there's an entirely new arraylist object created, presumably with an internal flag saying do only synchronized operations. But they must share the same internal data structure. So when I implement Synchronized(o), do I do this.... 1. Create a new instance of the CollectionBase-derived class. 2. Set a bool flag saying do only thread-safe operations 3. Copy the IList from the 'o' passed in to the new CollectionBase-derived class Tag: Multithreading and RollBacks Tag: 87111

    - Framework2.0B1 causes problems in Framework1.1 (IsolatedStorageException) Dear Group, I have a Web service, written in .NET Framework 1.1, which accesses isolated storage. Next, I installed Framework 2.0 Beta (dotnetfx.exe, file version 2.0.40607.42), to try it out. After installation, the old Web service could not access Isolated Storage: 'IsolatedStorageException: Unable to determine the identity of domain'. I uninstalled .NET 2.0 and everything runs fine again. I am filing report so you know what causes that exception. Regards, Jiri George Moudry Tag: Multithreading and RollBacks Tag: 87107

    - Config file to turn on/off features ? I am working on a project where I need to be able to turn on/off some features based on whether the user has purchased a particular feature. And, the current UI has a tab control which I need to hide (or remove) tabs based on this as well. My original plan was to use an XML config file and use that to determine whether a user gets to see a feature (or a tab page) and then remove or hide as necessary. If anyone has done something like this before and has any other ideas or suggestions, it would be appreciated. Thanks - dw Tag: Multithreading and RollBacks Tag: 87106

    - Problem adding control to toolbox I've created a strongly-named assembly which contains several custom server-controls which I want to add to the VS 2003 toolbox. When I try to add the assembly to the toolbox I get the following error: Insufficient State to deserialize the object. More information required. I tried a number of suggestions, that I found on the web groups (ie security settings etc) but nothing fixed the problem. Then I tried removing the AssemblyKeyFile reference from the assembly. This fixed the problem (why I don't know). Is there a way to add a strong-named assembly into the toolbox? Thanks, Glenn Tag: Multithreading and RollBacks Tag: 87097

    - Creating CHM files from assembly When you download and install the PayPal ASP.NET Web Controls (http://www.persistent.com/paypal/aspdotnet/), it comes with an impressive, MSDN-like compiled help file with detailed info for each of its classes. At the bottom of almost every page reads "Generated from assembly PayPal.Web.Controls [1.0.22.697]". Is there some .NET utility (or Visual Studio itself) that can render the assembly's XML as a help file? Or was this done using a third-part tool? Thank you, Eric Tag: Multithreading and RollBacks Tag: 87095

WindowsIdentity.GetCurrent().Name Environment.UserName SystemInformation.UserName Environment.GetEnvironmentVariable("USERNAME") These all return the local user (as expected).

Hi

I have a multi-threaded application that is of Parent-Child relation. For
example App1 will run and on completion fire App1.1, App1.2 and App1.3 which
can run in parallel. App2 depends on the successful completion of the last
three. If App2 fails or any of the three, I want the whole thing to
rollback.
How can I accomplished the rollback in multi-threading environment? Each App
writes to the db.

regards

Are App1, App1.1, App1.2, App1.3 and App2 separate processes or multiple functions on separate threads or a combination of both?

App1.1, App1.3 and App1.3 are all running on different threads. App1, on
completion, will trigger the three job
