• Windows Forms Help with Print sequencing

  I am working with a .NET application that renders pages to a printer in a specific order. I have the ordering down ok and according to my log file things are getting sent to the printer in the correct sequence. The trouble is that the printer is sometimes shooting them out in the wrong order. For the most part the order is correct but I have noticed this issue for a few forms. The client needs this sequence exact as they take these forms and will mail them out to the intended recipient. Any ideas on how to control the spooling     ...Show All

• Software Development for Windows Vista State Machine Workflow with partial Human Interaction

  I am trying to design a State Machine Workflow which is partially controlled by humans using a asp.net website, and on the other hand controlled by the workflow itself. To make this clearer an example: A product is defined using an asp.net website. This starts the workflow. To actually kick the workflow off, clearance (approval) is needed. This is done by humans using the asp.net website. Then the workflow checks certain parameters of the given product. The first check to be made is to look if the product already contains the product number. If it does, the next state is entered. If not a delay is used, to give the system time, to u ...Show All

• .NET Development How to decrease Form startup time?

  Hello, I have a .NET Form that displays the contents of a directory.  It works fine, but it can take 5 to 10 seconds to start and display.  If I close it and start it again, it starts faster.  How can the Form start time be decreased so the Form displays faster Thanks Mister T Another possibility is this simply has to do with caching... When you do a cold start, everything needs to be looked up off the hard disk to memory, which takes quite a bit of time.  Subsequent uses may take advatage of bits of that data persisting somewhere aside from the hard disk, also there could be code around ...Show All

• SQL Server Export Embedded Data regions to Excel problem

  I have a report that uses a matrix with an embedded table. There are no problems when you view/print it or export it to pdf. However when you export it to Excel the embedded table does not display. Instead the message 'Data Regions within table/matrix cells are ignored' appears where the table should be. Is it not possible to view embedded data regions in excel or perhaps some setting I have missed. I'm using Reporting Services 2000 with Service Pack 2. thanks Scott Then, did you changed the all reports OR you still living with this problem. I am also facing the same problem but am undecisive about the way I ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Can I develop the DX10 and DX9.0c application use VC++ 6.0?

  Can I develop the DX10 and DX9.0c application use VC++ 6.0 My develop environment is VC++ 6.0 and installed VSSP 5.0. VC++ 6 hasn't been supported by the DirectX SDK for quite a while now. If you go back far enough you can use DX9, but I think it was somewhere around December 2004 that VC6 support was dropped. The short easy answer is no. You'd be better of downloading VC++ 2005 Express (which is free) and using that. ...Show All

• Visual Studio Query Builder Re-use

  Hello, I have been trying to find the interface or Factory that would allow me to interact with the Query Builder that is used when adding a query to a DataSet. I have been looking in the Microsoft.VisualStudio.Data namespace but have mainly found the DataConnectionDialogFactory or the DataConnectionFactory... But I haven't been able to track down the Query Builder.... It looks like the Query builder is a reusable interface that has a connection string and query passed to it, but I can't find it for the life of me.. Anyone know how I can create an instance of the Query Builder from my code Thanks for any help Tim ...Show All
