• Visual Studio FormatDateTime expression

  I'm trying to use the expression editor to show just the date component of a date/time field. This is the expression that shows the whole date/time: =Fields!OrderDate.Value So I tried =FormatDateTime(Fields!RequiredDate.Value,"MM/dd/yyyy") which returns ##error. Ok, so I tried DateFormat.ShortDate, which won't compile. I tried it in quotes. I've tried just about everything. What does work is setting the format property of the textbox to MM/dd/yyyy, I'd still like to know how to use the FormatDateTime function to do the same thing. try this: http://forums.microsoft.com/ ...Show All

• Windows Forms How to add design-time support for custom control "wrappers"

  Adding design-time support for custom controls (i.e. MyButton) is well-documented. But the problem I am having is my control is just a wrapper (interface, that is implemented by a class which inturn holds a reference to the actual control) around the original control. Let me set the context first and then onto my question: We are using multiple sets of 3rd party control libraries (the standard winforms controls is one of them). Since we have different UI (for the same app), it wasn't feasable to have users (developers, end-user, etc) interact with the actual control and modify its properties/add children. So we have basic interface ...Show All

• Software Development for Windows Vista Ifelse activity in workflow

  How can I set the condition for the ifelse activity . how do I invoke the branching based on the condition. Raskal, I ended up writing an IfElseActivity of my own, due to an additional requirement I had. My requirement was to select multiple conditions for the branch, and I also wanted to pass parameters to the conditions. So I implemented an ifelse activity that takes conditions in the form of activities that implement an interface called IConditionActivity. You can go have a look and download the solution at: http://dotnet.org.za/hendrik/archive/2006/07/04/53953.aspx ...Show All

• Visual Studio IVsSolution::GetProjectOfUniqueName returns E_FAIL

  Hello, I'm trying to use IVsSolution::GetProjectOfUniqueName to get the IVSHierarchy of a named project.  I've used IEnumHierarchies to verify there is only one hierarchy in the solution, but when I call IVsSolution::GetProjectOfUniqueName, it returns E_FAIL. What might cause this problem Thanks, Notre Hi Notre, thanks for the excellent repro steps.  So on the call to project.UniqueName returns a name like project2.  Usually project systems like vb or C# will return a uniquename like project2\project2.vbproj or project2\project2.csproj.  When we call GetProjectOfUniqueName, it will ...Show All

• Visual Basic Processing Serial Data

  I need the reduce the processing time in a uMicrocontroller to allow faster sampling times. This has creates a problem in the data collection routine in VB. The old system collected the analog data a converted it to a decimal format before sending it to the serial port. This data is collected and saved using Hyperterminal. The VB program would, when run, would open this file and process the decimal data by graphing it. What I need is to capture the data directly and process a binary word. All attempts to run the graph program have failed! I'm sure it's in the way I'm reading the data. I've not been able to find much informatio ...Show All

• Visual Basic A Modest Proposal for Microsoft

  I've been a Basic programmer for over 30 years and that whole time I've endured the constant reminder that I'm not a "real" programmer. I know better and you know better but still there's that stigma associated with being a Visual Basic programmer vs. being a C++ or a C# programmer. Now that I use VB.Net it really couldn't be further from the truth since VB.Net does everything any contemporary OOP language does. So here's my suggestion, since Visual Basic.Net is about as much like Visual Basic as C# is like C, why not change the name of Visual Basic.net to B# Now instead of being a VB programmer, I'm a B# programmer.

  I currently have VB 6 and .Net 2003 Installed on one PC.   Can I install VB Express on it as well without any issues Yes, it appears to work just fine on my development PC: I have all three installed, including C#2005, VWD (2005), SQL Server 2000/MSDE and SQL2005 Express. I seem to recall a Microsoft article indicating that VB6 and 2002/2003 will co-habit with no problems, and one saying that 2003 and 2005 co-habit together also, so I guess VB6 and 2005 should be ok. phew! ...Show All
