• .NET Development Class Library using Encrypted XML, best practice?

  Hello all, I'm shipping an API to clients that uses a XML file for settings. The thing is that I need the file to be encrypted. Mainly because we dont want to expose internal components. The API reads the XML file and pass internal objects into objects we expose to the user of the API. We've been looking into using Public & Private keys and the RSA algorithm. Since, according to theory, if we keep one key to ourself and ship the other key inside the API, nobody can encrypt without the Private key...but it turns out that you can only Encrypt with the public key and when you Decrypt you need BOTH Public AND Private key. So it seems pointless to have encryption using RSA if you have to ship the object that Decrypts the data. So m ...Show All

• Software Development for Windows Vista Trouble with the ManualScheduler service and delays

  Hi, so I have this workflow I've been working on for a few months. It's made of a few parralel branches (5), which look like this : picture The whole thing is hosted in an ASP.NET webservice (in its global.asax file). Along with the ManualScheduler service (with UseActiveTimers on), I'm running a persistence, tracking and data exchange service. And while I thought I did everything right (according to other posts here), expired delays still don't cause the workflow to fire up, so I always have to wait for the runtime to do something (ie : instaciate another workflow, send an event to a workflow, etc...) before anything happens... (this, I assume is what it is supposed to do without UseActiveTimers activated). I really hope ...Show All

• SQL Server Cannot copy field names in column headings from view results

  When I am using a SQL Query I have an ability to control whether or not I am able to Include the Column Headers when copying or saving results. The control exists in the Options > Query Results > Results to Grid > Include column headings etc. My question is how to get this same ability when attempting to copy the results of a VIEW vs. a Query. The idea is that when I setup a view it’s a drag/drop type of query building (query building for dummies if you will). Once I have a view and click the Execute icon it will return all the records selected by the View. However, when I click the upper left/top box to select all rows and column and then try to copy/paste the records into Excel all the data copies just fine but th ...Show All

• .NET Development Possible to register a C# program to the R.O.T. for OLE automation?

  Hi all, I was wondering if it was possible to "register" your own created c# program for OLE automation This would be the equivalent of accessing something in Excel via OLE. Like: Dim ExcelApp As Object ExcelApp = System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application") Edit: and just to clarify, I understand how the GetActiveObject works (by looking up the object in the Running Object Table). I guess I need to know if it is possible to register a program with the Running Object Table. Great, thanks again Alois. Hopefully this is my last question: I've managed to register my program with the ROT, and I can see it fine with the correct name! :) Now, accessing it is giving me some trouble ...Show All

• Visual Studio Express Editions How to deploy VC 2005 Express SP 1 solutions?

  Hi, I am quite confused about the deployment politics we should use with the Express Edition. Since there is no Support for Setup projects -- with merge modules -- in Express Edition , we had before SP1 the possibility either to use private SideBySide Assemblies (for instance with a local Microsoft.VC80.CRT.manifest) or the vcredist_x86.exe. Using private Side by Side assemblies for the VC Redistributables is not recommended by MS (See for instance in Article "How to: Deploy using XCopy ") Service Pack 1 introduces a new revision of the WinSxS Microsoft.VC80.CRT assembly but the vcredist_x86.exe is not updated. VC20005 SP1 should fix this KB 919588 issue, but I don't see how, since there is no new vcredist_x86.exe for Express users. So I ...Show All

• Visual Studio Cannot debug MFC source after upgrading to VS 2005 SP1 using symbol server

  I have VS 2005 and SP 1 installed and have enabled the symbol server in "Tools -> Options -> Debugging -> Symbols". It is no longer possible to step into MFC source code when debugging an MFC application. This used to work with VS 2005 without SP1. The only workaround to my knowledge is to disable the symbol server. Then the .pdb from the symbol server will not be used. If I understand this correctly. the .pdb from the symbol server (http://msdl.microsoft.com/download/symbols) now has source information stripped and so will prevent stepping into MFC source with the debugger. Thank you! Yes, that works like a charm. I had to delete all files from the symbol cache first. ...Show All

• Software Development for Windows Vista Application Opens By Itelf Fine, But When Opened With Process it fails to load components

  Hey Guys I am trying to find out why this happens.
