• Windows Forms Need help formatting a ToolTip please

  Hi, I'm coding VB.NET using VS.Net 2003, and I've got a datagrid that lists customers and the time spent working for each customer. When you mouse over the time field, a ToolTip that breaks down the specific minutes worked on for each job/task for the customer. Unfortunately, the way it is formatted now, the minutes just appear inline, right after the the job description....so the minutes don't line up from one row to the next (because the job descriptions are different lengths). Is there any way to create a ToolTip that has two columns (one for job description and one for minutes) Or, if that's not possible, is it possible to set the fo ...Show All

• Visual Studio Tools for Office vbScript with .NET

  With Visual Studio 2005 and Framework 2.0 you discontinued the Microsoft.Vsa namespace. How do I execute vbScript in your latest framework without having to return back to your COM MSScriptControl (C:\WINDOWS\System32\msscript.ocx) I have not tried that yet, but I will. However, I did try running a simple test subroutine with no problems. Sub Test1 'Todo:... End Sub (It was actually passed in as a BSTR: "Sub Test1\r\n\t 'Todo:... \r\n End Sub") There were no errors... can you see why this would work but not a function even though the sub was not public ...Show All

• SQL Server Possible to display RTF from db? Is there a control?

  I'd like to save RTF (or html, possibly) in a memo field of a table then display that as formatted text on a report. Can this be done I've used a control (RTFedit) in Access to do this, though the results were mixed. I need to display tables with formatting.

• Visual Basic Object instance lookup & lifetime

  Hi there, currently still using VB6 but exploring the move to VB.NET. We have a multi tier application with a tier in which we have created object classes representing table records (Flight, Booking, Airstrip, Passenger etc.) Since these objects are referring to each other we need to be aware that we do not create more than one instance in memory for a certain FlightID. Hence we have a "cache" (dictionary) which holds a reference to every instanced Flight object etc.. This in order that the Passenger.Flight and Booking.Flight actually refer to the same flight instance. The question is this: - In VB6/COM you could (with difficulty) find ...Show All

• Software Development for Windows Vista Customizing work flow

  Hi, I have a requirement where I should be able to define a workflow for approval process (ASP.NET). However, it should be possible to configure the workflow for different client needs. For example, my workflow has 10 steps. First client might go through all 10 steps of the workflow but the second client might not require a couple of steps inside that workflow. Is it possible to configure the workflow like that In that case, what kind of workflow should I define to cater this need Is it possible to configure the workflow steps on a parameter (e.g. per client) I don't want to define different workflows for different clients.

• Game Technologies: DirectX, XNA, XACT, etc. DirectDraw and Transparent Dialog boxes, flickering

  I am using XP, VC++.NET 2003, and VideoLAN (activex) for streaming video. VideoLAN uses DD2 for most of the drawing, and seems to cause issues with a transparent dialog box sitting over it. It will flicker as VideoLAN (DD2) invalidates the region sitting on-top (the transparent dialog). Is this a problem becuase they use DD2 and not D3D9 Would converting their code to D3D9 stop the flickering I basically want to have an overlay plane that can alpha-blend fade-in and fade-out on-top of VideoLAN. All works perfect, except for this flickering. If I tell VideoLAN to clip itself, it operates as an overlay, no flickering, but no alpha blendi ...Show All

• .NET Development Using FtpWebRequest to check if a directory exists.

  I'd like to know if there is anyway i can use the FtpWebRequest class to check if a directory exists before creating it on the server. The reason i ask is because if you try to create a directory that already exists it throws a WebException and disconnects from the server. This gives a performance hit if we are trying to create alot of directories on the server that already exists due to the disconnects/reconnects. TIA, lushdog Yes, you can set the FtpWebRequest.Method to "NLST" and use it to check if the directory exists on the server Mariya ...Show All
