• Software Development for Windows Vista Printer Drivers for XPS Documents On XP and Server 2003

  Will there be printer drivers that operate on XP/Server 2003 for XPS documents I am familiar with the MXDW writer. Can I make an assumption that to take full advantage of XPS, one has to use Vista as this OS will have the full compliment of printer drivers I have searched but either this is a dumb question or have not framed the search query right. Thanks Take a look at the XPS Essentials pack (currently its beta2 is released). I believe it contains a printer driver that will work on w2k and up... (somebody should correct me if that is wrong...) Thx, Rob ...Show All

• Software Development for Windows Vista How to use DirectShow in a multithreaded application

  Dear DirectShow forum, When I call functions related to the filter graph from a different thread than the one the filter graph was created on, strange things happen (functions cause errors or do not return). How can I use DirectShow in a multithreaded application P.S. I am using DirectShowNet in the C# language. Thank you! wtrn Hi LGS, I am creating the thread which calls the DirectShow functions with player = new Thread(new ThreadStart(Render)); player.Start(); I am not using any [STAThread] or [MTAThread] attributes, so I understand that the thread is created as MTAThread by default. I tried adding player.ApartmentState = ApartmentState.STA; before player.Start(); but this did not change my outcome. Lo ...Show All

• Visual Basic Slow Timer

  Hi, I've written a program that uses a timer to control an external relay (via USB) that turns on a light. The problem I'm having is that the timer is slow (about 4 seconds per minute) on my desktop computer, but its timing perfectly on my laptop computer. I've retested this on other computers and I get a similar result. Is there a way to ensure that the timer is right on everytime Its also worth noting that the clocks on all these computers are keeping the correct time. Thanks, P Post your code.  If the timer is just set for, say 60,000 (once a minute) then switch to something like   Timer.Interval = 1000 Private Sub Timer1_Tick( ByVal sender As System.Object, ByVal e As Sys ...Show All

• SQL Server Error creating Subscription to reports

  Hi all,   I am having a HUGE issue with SSRS, I am running SQL 2005 on Win 2003 server, the SQL uses SQL and windows permissions. I have a datasource which stores it credentials securely on the server but for some reason when i try to subscribe to the report it errors saying "Subscriptions cannot be created because the credentials used to run the report are not stored, or if a linked server the link is no longer valid." Beats me but the credentials are stored, I am  connecting using a user account which can run the report fine (This is proven). I have SP1 installed, and have literally tried every last option in the book.   N.B i have read all the existing post about this and i seem to have a different ...Show All

• Visual C# True Copying Reference-Value Objects

  I have stumbled upon the following problem: Given an object (any reference-value class) O1, how can I copy it to another object O2. O1 = O2; //will only copy the reference, but I want a new object being exactly identic to the old one. Also, how can I do the same thing on an Array int[] arr1, arr2; arr1 = arr2;// also, doesn't work, only copies the reference Hope I made myself clear enough. Thanks in advanced.

• .NET Development Countdown Timer

  I can't figure out how to make a timer countdown rather than counting up, I know that it has to do with System::DateTime::Subtract. I have a DateTimePicker, and I want the timer to start right when you change the value of the DateTimePicker, and I want the countdown to be counting down from the value I choose. For example if I choose August 14, 2006 on the dateTimePicker, I want the timer to be counting down from that date. Try this: System::TimeSpan diff = System::DateTime::Now.Subtract(dateTimePicker1->Value); label2->Text = diff.ToString(); You probably want to format it a little nicer, I'm sure you can figure that out... ...Show All

• Windows Forms allow nulls in databinding with DateTime datatype and typed dataset

  Greetings, I want to be able to use databinding with null values, specifically datetime. I found that the datetime type isn't even nullable without using "DateTime ". So, I have a custom control with a property called value which is of type DateTime . public DateTime Value { get; set; } So now, I want to databind to this property, as it will allow null values for the DateTime but the typed dataset doesn't provide a DateTime datatype. Is there a way to bind to this datatype ...Show All

• Visual Studio Team System Cannot use the Performance tools

  Hi, I'm trying to use the Performance Tools built into VS2005 but can't. Nothing happens when I try to create a new performance session, use the performance wizard or even view the performance explorer. (i.e. I click the menu item and nothing happens.) I think, I may have accidently removed it. Can anyone please tell me how to get it back. Thanks. I'm not able to create a new performance session or interact at all with the performance tools. Just before the incident, I installed Crystal Reports XI Release 2. After this, I tried opening a saved performance session - that had a crystal library. VS complained and closed the performance window and that was the last I interacted with the perfomance to ...Show All

• SQL Server Combining Output PDF files

  Is there a way to output reports to the same PDF file. Basicly Appending several reports to the one PDF. Without combining the reports using subreports, I think you would use code & custom PDF components, unless you want to jump into writing a rendering extension. Softartisians Officewriter & abcPDF.NET are two possible options. You can also try automating Acrobat. http://www.planetpdf.com/forumarchive/84747.asp One alternative may be to export to a different format and then convert to pdf afterwards. cheers, Andrew ...Show All
