• .NET Development ASPNET Membership

  Sorry - I posted a similar question in the VS General forum then thought this might be a better resource. I currently use a SQL server DB for a web app. I am re-writing in dotnet and would like to use the membership features of framework 2.0. I already have user tables, however and cannot find info on how to convert those users to the aspnet_Membership users. I tried to execute the aspnet_Membership_createUsers SP by setting up values for the parameters in query analyzer, but then passwords and such are not hashed or encrypted as they are if you add the users using the Create client interface. I am already storing the user id and pass ...Show All

• Visual C# ComboBox - set selected index

  Hi, I have populated a combobox with a dataadapter and set the DisplayMember and ValueMember as required. So, the conents are essentially: 1 Apple 2 Orange 3 Banana (Obviously, only the fruit names are visible in the combo) My problem is, that if I want to display a form with the combobox and set the selected index to the item which has fruit if # 2 (Orange). How do I determine which one I want. Do I have to loop over the contents and check the ValueMember value for item I suppose I could populate the combo without an adapter, but can I add both a valuemember and a displaymember that way Thanks, CW I actually do q ...Show All

• SQL Server beginner question - instances VS. separate databases?

  Hi, I hope this is the right place to ask this question. I'm trying to get started programming databases against SQL Server Express. I'm pretty confident in understanding the techniques of how to access a database, a specific table, retrieve rows, etc. However, I’m having endless frustration in understanding the very rudimentary basics of how the SQL system even works. I know I don’t need this information to program against it on a simple level, but if I want to develop robust applications that I can distribute properly I need to know this, and it just seems so much more complicated than when I used MSDE.

• Visual Studio "Report is being generated" message not showing

  I am retreiving data from Oracle and has about 10 parameters. The report renders ok, but there is no wait message and the nice little green swirl graphic! Any idea Also, how do I show the Print button I set it to true, both declaratively and programmatically to no avail. Thanks! There is a property called ReportViewer.ShowProgress which determines whether the green swirl is displayed. The Print button is not available in ASP.NET ReportViewer when in local mode. You can still print programmatically if you know which printer to print to. The print button is available in ASP.NET remote mode, or WinForms local and remot ...Show All

• Visual Studio 2008 (Pre-release) using 32bit and 64bit dll..

  We have a plan to upgrade our APP for Vista. And I have a some of question about it. some of DLL or Com are still made with 32bit. I want to use thouse. So my question is Can I use 32 bit and 64 bit DLLs or Coms, in same 64bit APP This is not an Avalon-specific question. In general: Most existing 32-bit apps should run just fine in WOW on x64 Windows. 32-bit DLLs cannot be loaded in a 64-bit process. A 64-bit process can talk to a 32-bit COM LocalServer. (This may be the easier way to reuse your existing COM components--out of process.) Managed code is usually compiled to platform-independent IL, so the process ...Show All

• Visual C++ Linking: libcimtd.lib requested

  Hello, after conversion of a VS6 project to a VS2005 project, the linking broke down with a fatal error as some "libcimtd.lib" was not found. libcimtd.lib is no part of VC/lib (but libci, libcmtd are). After including libcimtd in the list of libraries which are ignored at linking, everything worked. Cheers  Michael Mixing C and C++ I/O should not be a problem. It is mixing old VC6 iostream headers and new stream headers from Standard C++ library creates a problem. At least this is what I think the problem is looking into list of errors you mentioned.

• Visual C# generics constraints for types implementing operators

  I'm trying to build a class public class SignalBuffer<T> where T is any type that implements the + and the * operator (mostly double or my own complex number type ) How can I add a constraint to SignalBuffer that constrains T to types implementing these two operators I tried just using public class SignalBuffer<T> where T : double, Complex but of course this won't compile because you can't use double in a constraint Another thing I don't understand is why it is possible to make generic methods like this public myType myMethod<T> ( T var1, T var2 ) but not generic operator overloads ...Show All
