• Visual C++ Strange C2664 in Visual Studio 2005 C++ release candidate (v8.0.50727.26)

  I'm converting a project from VS 6.0 SP5 to VS 2005 rc.  I'm getting this really odd C2664 error.  Unfortunately, the project is very complex and I have not yet been able to reproduce this behavior with a simple example.  I can, however, offer proof  of its strangeness:    DBString dbx = m_scCal. operator const DBString();    DBString dby = m_scCal;    DBString dbz = ( const DBString )m_scCal; Of the three example statements above, only the first one compiles.  I have no idea how it is that an explicit invocation of a converstion operator via the "." syntax can wo ...Show All

• Visual Studio 2008 (Pre-release) About the STS pattern and interoperability (WS-Trust)

  Greetings, I am proposing a STS in a solution. The prototype i did is based on the STS implementation available in the "Federation sample" and it works very well when i a am using WCF to both ends. However, i have strong interoperability requirements as the services clients are gonna use heterogeneous platforms. This STS sample's contract is pretty simple. It only has one operation to issue a security token. I have looked at the STS implementation found in the "Microsoft Federated Identity and Access Resource Kit - Sept 2005" and what confuses me is that this one has a contract (named IWSTrustContract) which (as ...Show All

• Windows Forms MDI Maximized children forms without controlbox?

  MDI Maximized children forms without controlbox I have been searching the web and everywhere I asked the question, the answer is that it is a Microsoft Bug. Well instead of telling me that it is a bug, how do I fix this My situation: I have a parent form (frmMain), a welcome/startup (or background) form (frmWelcome) and other child forms for data capturing. The idea is that when the program runs, the welcome form is displayed and stays displayed as a type of "background page", displaying outstanding jobs and other system info. All forms, when opened, must be maximized, thus eliminating the need for the minimize box or maximize box but s ...Show All

• Visual C# Bound and unbound calculated columns

  I have a datagridview control bound to a .XSD dataset object.  Of course, it automatically added all of the columns from the dataset.  I edited the columns and set the Visible property of the columns I wanted to hide to false.  How can I create a calculate column and add it to the datagridview.  Example, my dataset has LAST_NAME and FIRST_NAME columns.  I want a single column in my dataviewgrid called name that is the format of last name, first name.   I tried adding an unbound column in the designer, but I am not sure how to set its values from the other columns.  In code I created a new datacolumn using a ...Show All

• Software Development for Windows Vista Various comments on Default application projects

  I've been playing a bit with beta 1 and beta 1.2 and there are a few things I'm not very comfortable with in the default code generated when you create a new Workflow project (C#). For example, the default exe projects (e.g. sequential workflow console application) have absolutely no error handling at all. Now, I'm assuming that many people might just fail to notice this and either use the generated code in Program.Main as is or with little modification, in which case their workflow projects will simply hang in case of an unhandled exception inside one of the workflow tasks, with no indication of anything that might have happened. This is b ...Show All

• Visual Studio Problem building Managed C++ project with Msbuild that has multiple assembly references

  I have a VS2005 solution that includes a Managed C++ project as well as several C# projects. The C++ project references several of the C# projects. All projects in the solution reference log4net.dll (as an AssemblyReference). My C++ project builds without any warnings using the VS2005 IDE. However, when I build the solution using MSBuild, I get zillions of warning messages such as: log4net.dll : warning C4945: 'LogicalThreadContextProperties' : cannot import symbol from '<some path>\log4net.dll': as 'log4net::Util::LogicalThreadContextProperties' has already been imported from another assembly 'log4net' For my managed C++ proj ...Show All

• SQL Server OLE DB Destination - table name variable

  Hello, In my Data Flow I have a OLE DB Destination that needs to get the table name to write the data to dynamicaly from a variable I created. So I select "table name or view name variable" from the Data access mode and select my variable below.

• .NET Development DownloadFileAsync Threading

  Hi All, Trying to encapsulate the WebClient class and DwonloadFileAsync method in a separate class/assembly (business object), so that I can download and keep track of multiple downloading files. Is there any way to marshall the data (progress, completed) info, back to a WinForms assuring that my WinForm controls will be updated on the thread upon which they are created as to avoid CrossThreading issues. I have been beating my head for 4 days and tried almost everything under sun, but to no avail. I'd like to specify an indicator control per class instance so that each file's progress indicator is updated accordingly and safely. I a ...Show All

• Visual Studio Team System Source Control Explorer

  I find the new way of dealing with Source Control in the Source Control Explorer very frustrating.  It seems like another case of the tool dictating how I work, rather then letting me work the way I need to. I want organize and include other files in Source Control in a "Non-Solution" way.  I have Word Documents, Images, Text Documents, Help Files, etc.. that do not belong to a VS Solution, but I want to keep them under version control. In VSS6, it was a simple matter of dragging the files/folders I wanted to keep under version control onto the Tree.  I cannot do that with the SCE. I may want to exclude certain things.  I ...Show All

• SQL Server Aggregating time stamp data for a time series plot
