• .NET Development Reducing memory usage with XslCompiledTransform

  I've currently been using and XslCompiledTransform in my software to apply an XSL stylesheet to a user-provided XML file and then bulkloading the resulting file into a SQL table. This worked great until an XML file larger than 100 MB is thrown into the mix. The RAM usage jumps off the charts and for most users, my program exits will an OutOfMemory Exception. I've looked for ways to get around this and cannot seem to find any solutions. What can I do differently or what other alternatives do I have other than physically parsing through the XML file line by line (or node by node) and performing the operations the XSL file does myself... which is my LAST option considering I am sometimes dealing with 2GB and 3GB XML files. Oh.. and here's ...Show All

• Visual C# Catch Errors from Creating DLL Instance

  I have a widget type application that reads all of the dlls in the plugins directory and creates an instance of each. I want to be able to catch the error of the individual dll without having to exit the entire application. Right now I'm calling the dll's like this: WidgetContainer.Container c = new WidgetContainer.Container(); c =(WidgetContainer.Container)Activator.CreateInstance(pluginAssembly.GetType(pluginType.ToString())); c.Show(); Everything loads fine, but if one of the dll's has an exception the entire app closes. Is there a way for me to redirect all of the errors to the base application Thanks JGA Rather than me cobble something together, check out a post from Richard Lander. http://hoser.lander.ca/AppDomain+Unhandled ...Show All

• .NET Development Navigating Large Database

  I have a SQL database table with about 1,000,000 records. I would like to be able to view these records on a form, linked to textboxes and such, and be able to navigate through them, as in back and forth. I have tried using the dataset and it is extremley slow to load the dataset. Its so slow it would not be usable. Does anyone have any suggestions on how I would be able to navigate through these records I would suggest to implement search capabilities inside ofthe application. Users usually would ike to get some set of records based on condition(s), not to navigate through all the records. It will allows to narrow down selection and will allow application to work with small amount of records ...Show All

• Visual C# Terminating a process using WMI

  Hi, I have been told that this is possible but I can't seem to find any sample code anywhere. Anyone know how to do this Thanks. using WMI, be sure you added a reference to System.Management.dll and imported the namespaces, System.Management and System.Management.Instrumentation. we then execute a query and execute the terminate command: ManagementScope theScope = new ManagementScope ( "\\\\ ComputerName \\root\\cimv2" ); ObjectQuery theQuery = new ObjectQuery ( "SELECT * FROM Win32_Process WHERE Name ='ApplicationName. exe ' " ); ManagementObjectSearcher theSearcher = new ManagementObjectSearcher (theScope, theQuery); ManagementObjectCollection theCollection = theSearcher.Get(); foreach ( Manag ...Show All

• Windows Forms Magic Issue of ZoomFactor of RichTextBox!

  I write a simply code to Repro this issue. float zoom = 1.4f; string ss = this.richTextBox2.Rtf.Replace("\0", ""); this.richTextBox1.Rtf = ss; //this.richTextBox1.ZoomFactor = this.richTextBox1.ZoomFactor * (float)0.1; this.richTextBox1.ZoomFactor = zoom; When I run these code, the richTextBox1.ZoomFactor always 1.0. And after comment out the yellow line, the ZoomFactor is right to 1.4 Do you meet this issue before, and how to explain this issue Thanks! Hi If you look at the docs on MSDN for ZoomFactor it tells you that if the font you're using isn't TrueType then the zoom factor gets rounded to the nearest whole number so maybe that's the issue here HTH Martin ...Show All

• Visual Studio 2008 (Pre-release) Dotted Border

  Hi! Is it possible to set dotted style of Border Something like " Rectangle.StrokeDashArray" There's no straightforward way of doing this, unfortunately. Part of the problem is that Border allows non-uniform widths, and it's unclear what it means to dash in that case. If you are trying to replicate FocusRect-type functionality, let me know and we go down that rabbit-hole. Otherwise, here are some other thoughts you may wish to consider: First, you can get something that looks somewhat reasonable using a checkerboard brush:   <Border Width="100" Height="100" BorderThickness="1" SnapsToDevicePixels="True">         <Border.BorderBr ...Show All

• Visual C++ Function name conflict with ENUM name

  Suppose I have a ENUM T_MuxPos_type, where T_MuxPos_type{fixed;flexible;}. While I am coding, I have T_MuxPos_type Mux_pos. When Mux_pos = fixed, I have no problem with gcc but a compilation error with mvs2005: c:\mvs2005\bs_module\source\config.cpp(1925) : error C2872: 'fixed' : ambiguous symbol could be 'c:\panliu_bs\mvs2005\bs_module\source\declareenum.hpp(43) : T_MuxPos_type_E fixed' or 'c:\program files\microsoft visual studio 8\vc\include\ios(183) : std::ios_base &std::fixed(std::ios_base &)' If I solved this problem by Mux_pos = T_MuxPos_type::fixed, gcc compiler will complain about it.
