  Hi. I have two groups and a detail row in a table.First is ProductGroup, second is ProductSubgroup and the detail area's name is ProductName. My problem is that I want to keep the detail and the ProductSubgroup (second group area) together.For example sometimes ProductSubgroup is written at the end of the page and the detail area is on the next page or the ProductGroup (first group area) is written at the end of page and the ProductSubgroup (second group area) is written on the next page.And I don't want this.But for example the ProductSubgroup area contains too many detail rows and this time I want to split the records two pages.I hope you help me.Thanks!

• .NET Development error: c101008d

  Hi all, I have the following minor but annoying error whenever I build my application for the first time after modifying its code .

• Visual Studio Windows installer problems

  I ran into some virus problems a few days ago and thought that I had fixed them.  I then received access to install Visual Studio 2005 and Windows XP PRO embed SP2.  I checked for comapatibility of XP PRO with my computer and everything checked out fine.  I was too hasty in the install of XP PRO and forgot to make a system restore point before the install.  After the install everything seemed to work just fine but then windows installer popped up.  The windows installer box just says "initializing installation" and does nothing else.  If i click cancel on the box, it says "canceling installation" but does not go away.  Eventually it will give a message that says "retry or cancel" and I hit cancel and then ...Show All

• .NET Development How can I have one and just one copy of my application running in the same time???

  How can I have one and just one copy of my application running in the same time I did somethign similar a while ago; doing something like this is so popular that I blogged about it here: http://dotnet.org.za/ernst/archive/2004/07/20/2887.aspx What makes it neat is that, if an existing instance of your application is already running, it will bring it to the foreground and maximize it. With the inspiringly named "helper" class (linked to from this blog-post) you're able to write: public static void Main() { bool firstInstance; Mutex mut = new Mutex( true , strSystemMutex, firstInstance); if (firstInstance) { try { Application.EnableVisualStyles(); Application.Run(new frmLogin()); } catch (Exception ex) { Excep ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What is MultiSampleQuality

  Hi, I'm curious as to what exactly MultiSampleQuality is. I understand how to set fsaa with MultiSampleType using a PreparingDeviceSettings Event Handler or just fiddling with the presentation parameters can calling Reset(). But to fulfill my curiousity, I was browsing the docs and saw little documentation on MultiSampleQuality. I understand I need to set the Type to NonMaskable to use the MultiSamplyQuality Or it must beset to an int less than the Type. What is that int all about and MultiSamplyQuality all about Thanks It doesn't mean anything on the Xbox. The 360 implements multisampling directly inside the special memory chip that holds your framebuffer data. This makes it obscenely fast, but no ...Show All

• .NET Development How do I specify paramaters from my SqlDataAdapter.Update method?

  Hello, I have some code that takes the data from my local machine and then sends it across the network to an SQL server 7.0 backend. Here is my code: myDS.Tables("tblName").Rows.Add(myDataRow) mySQLDataAdapter.Update(myDS, "tblName") The problem that I am facing is when the second line runs, it adds to the data that is already in SQL server 7.0. What I want it to do is update the data on the network where the ID from the local machine is the same as the ID in the data on the network server. Is there a way to specify logic in the SQLDataAdapter.Update as such... mySQLDataAdapter.Update(myDS where id = id, "tblName") Thanks in advance. Hi, the pr ...Show All
