• Software Development for Windows Vista Design: Loops and Workflow

  The performance hits for while and other canned loop activities are a concern. This brings up a general design question: is WF suitable for enterprise level processing of thousands (possibly millions) of items in loops The performance guidance says to write custom activities for this sort of thing, but that kind of takes away a lot of the benefit of using WF vs. "just code" in the first place. Any thoughts Anyone processing a 2 million line flat file using WF What is a good approach for this using WF or is it not a suitable technology to drive the looping sequence Thanks! I happen to feel confused while reading the book "Essential Windows Workflow Foundation". If " The new chil ...Show All

• Visual Studio Report with subreport works fine on development server - "Unable to connect" when deployed

  I'm using ASP.NET 2.0 and whatever version of the CrystalReportViewer that comes with Visual Studio 2005. I have a report that uses a dataset as a report source. It includes a subreport with a parameter that links it to the data in the main report. It's nothing fancy - just what gets generated from the "Subreport Links" dialog. Everything works great on my development machine. However, when I run it from my deployment servers, opening the report throws an error: "Error in file <temp file name>.rpt. Unable to connect: incorrect log on parameters." I've traced it down to the Subreport Link. If I don't include a subreport link in the report, everything works great on the server. Of course, I need that link to make my ...Show All

• Windows Forms My .NET form goes behind others after COM goes away

  I have a .NET form written in C# (VS2005 SP1) that instantiates a COM object. That COM object brings up a VB6 form. When I close the VB6 form, my .NET form disappears behind any other forms that happen to be open such as Windows Explorer windows for example. I have to click its icon on the taskbar in order for in to come back to the front. EDIT:  It appears that its not that the form is going behind, but that the window where the task was launched is brought forward, and given focus.  If I run from the debugger, VS2005 gets the focus, and if I run the EXE from a Windows Explorer, then WE gets the focus. Is there a way to keep my .NET form in the foreground Thanks! ...Show All

• .NET Development return argument has an invalid type

  I'm having some trouble with a .net remoting issue. Our code connects to an Active Directory DB in which records are stored. There are two spots that we have to do this. First there is a Windows Forms User Control that is sitting on a form. The second, and you're going to love this, is the same forms user control embedded into a webpage through an object tag. The scenario with the control and form works without a problem. We are able to connect to AD and transfer information. The web scenario though fails on us everytime. The main exception that we are getting is: System.InvalidCastException:Return argument has an invalid type at System.Runtime.Remoting.Proxies.RealProxy.ValidateReturnArg(Object arg, Type paramType) at System.Runtime.Remot ...Show All

• Windows Forms Disable/Enable Tab Page

  I read the thread containing information of how to accomplish disabling a TabPage by using OwnerDrawing methods.  Problem is that for some reason, my "disabled" tab is apparently too small for the text.  As such the text ends up getting wrapped to a second line, messing up the text positioning on the tab itself.  How do I increase the size of the actual "tab" of the TabPage Note: I tried adding spacing to the Text property of the TabPage if I found that the TabPage was disabled, but apparently changing the Text property fires off the DrawItem() again, which ended up putting me into an infinite loop. The original thread I found was: http://forums.microsoft.com/msdn/showpost.aspx postid=13047&siteid=1 Actually, ...Show All

• Visual Studio Tools for Office VSTO 2005 SE - Outlook 2003 Addin - Deployment problem

  I followed every point shown on: http://msdn2.microsoft.com/en-us/library/2ac08ee2(vs.80).aspx On my machine with WinXP prof, VS2005, addin works fine. But on the other machine (test machine, WinXp Prof, VSTOruntime, Office 2003 prof, O2003PIA, .NET FW.2.0) is didn't want to start. I used setup (created with VS05 O2003Addin solution) to install my plugin. I double checked every registry entry and they are fine to me. Could anybody tell me what's wrong Please give me any idea where to start. You might try a machine policy, i.e. -m instead of -u Also check before you restart Oultook in TaskManager if Outlook.exe has really exited when you closed it. -- SvenC ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. persistent backbuffer OR renderTarget (on 360) possible?

  I want to disable backbuffer clear. Though I have removed the Clear from my draw func it still gets cleared to black on Xbox360. Run the same thing on PC and the mystery clear doesn't happen (stuff I'm drawing correctly smears across the screen). I also tried to workaround w/ ResolveBackBuffer to a texture and draw this back at the beginning of each frame but thats not working for me either. In this case my Draw() looks like: Draw Backing Texture using Quad Draw new items ResolveBackBuffer -> Backing Texture I even tried double buffering the backing texture w/ no luck. Thirdly, I tried RenderTargets, but they also seemed to be getting cleared each frame as well! I would think there's gotta be a way for rendertarget contents ...Show All

• Smart Device Development Why are ListViewItem's and ColumnHeaders so limited

  I just got done creating a BindableListView control in the full framework with a full designer interface one would expect in a 2.0 bindable control. I wanted to port it to the compact framework (where i need it the most) and when doing that I find that 1. CF yells at all my deisgn time only attributes. 2. ListViewItemCollection and ColumnHeaderCollection both do not have constructors and thus I cannot inherit them to give VS the ability to add them via the designer. I can still use my BindableListViewItem and BindableColumnHeader classes but all programmatically and not visually like I wanted. I guess I'm just wondering why those two classes were given no constructors and thus made unable to be inherited The metadata lists a bunch of vir ...Show All

• Windows Forms VS 2005 applet deployment

  I've developed a small console application that imports data from a group of Excel spreadsheets using ADO.net, that are spread across a shared network drive . The application works fine when I use it on my workstation with WXP pro. But I try to schedule it and use it on a Windows 2000 Pro Server I get import errors, as if the application is not reading the number values from the spreadsheets. I've checked the ISAM versions and their the same so I'm stuck. Any Help would be appreciated Thanks HC Thank you for your quick response. The application all it does is upload Excel data to a SQL db , for whatever reason in WXP Pro it will read the numbers and the strings from cells on the Spreadsheet, but ...Show All

• Visual Basic Open and Close DB Connections

  Hi there people, I am in the process of creating a DAL for my application. I have created all the functions to query\insert\update the data in a set of modules for each table. My issue\question is. I cannot decide how to handle the connection to the database..i.e. the open and close of the connection after each query\insert etc has fired. here is a brief layout of my module i have created public SQLCON for connection and SQLCMD for the command objects then I call them from each function.
