• Silverlight (formerly WPF/E) updating SplineDoubleKeyFrame properties from javascript

  behaviour is pretty errant, sometimes I can get it working other times don't. I can't find the logic why it breaks on me. basically I have in screen 100 elements, all created dynamically, looping over them updating their storyboards props and trying to move them around.   in javascript it goes something like: for(var n=0;n<100;n++) { var target = wpf.findName(objectID); var storyboard = target.findName(storyboardID); var currentValue = target.findName(objectElementID[objectElementProperty]); var startKeyframe = storyboard.findName(startKeyFrameID); var endKeyframe = storyboard.findName(endKeyFrameID) startKeyframe.value = (currentValue).toString(); endKeyframe.value = (value).toString(); // thi ...Show All

• .NET Development Need help understanding dynamic DLL loading

  Hi all, need some help with dynamic DLL loading. I am trying to create an application that will instantiate a class (from a DLL) at runtime. The type, exposed properties, and exposed methods of the instantiated class are known (inherited from a custom designed class). Using Assembly.LoadFrom([Path]) coupled with Activator.CreateInstance(type, param()) I was able to almost instantiate the class (for some reason I get an parameter error, will explain more). Unfortunatley the LoadFrom() will place a LOCK on the DLL and I am unable to replace the DLL with a newer version even after the application has been closed in the Debugger. The idea is that these dynamically loaded DLLs will be loaded and unloaded wehenever needed (similar to object in ...Show All

• Visual Studio 2008 (Pre-release) CommunicationException was unhandled

  When doing multiple client load test using wcf Service with tcp , i get the following error. The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '10:10:49.6250096'. The same code is working fine for single user version. The service has http and tcp end point. Http end point is working fine with multiple client. Hi, I have a similar problem. When I use a HTTP client there are no problems. But when I use a TCP client the following exception is thrown on the server: System.ServiceModel.CommunicationException The socket connection was aborted. This could b ...Show All

• SQL Server Turn the list ?

• Microsoft ISV Community Center Forums Using Autofilter in VBA with a range of criteria

  I have working code to autofilter the list I'm interested in for a single criterion in several fields. However, I can't find anything anywhere that shows how to write the object model fields so that I can use a date range. ie. I thought that I would be able to use RangeObject .AutoFilter(Field:=1, Criteria1 > Date1, Operator:=xlAnd, Criteria2 < Date2) I'm not sure that it's possible, but maybe someone knows a workaround. Well, I believe that I finally found an answer by trying to concatenate strings to make the thing work. It might not be the slickest way, but I thought I would post it since it works and someone else could have a similar question. startweek = InputBox("Enter the desired Week Number ...Show All

• Visual Studio Team System TypeCastingProblems.cs

  I'm sure you guys don't think about issues that are so obvious nobody would every write code that way. I've found out recently that there is a lot of bad code out there that could be easily caught in FxCop. In any case please consider adding the following rules to FxCop. I've written them myself and found too many violations to count. Anyway here we go. 1) Don't call ToString() on a String. I've found that some developers put .ToString() on the end of almost everything. This only catches part of the problem but is a good start. 2) Use Type.FullName instead of Type.ToString(). This is still the developer problem of always putting ToString() on the end of everything. I've also found that this finds a bunch of problems where the code is ...Show All

• Visual C# Time of day arithmetic

  Hi. I am working with a time string that I want to be able to add a value to. If I enter a time of day as hhmm (example 2000), I would like to add a time value as hhmm (0535 + 2000 would return 0135) and return this as a string. Can someone help me with an easy way to do this please Thanks. My current routine doesn't work, but here is what I have done in sourcecode. The only part that seems to fail is the adding of hours and minutes to the time. Is there a shorter or better way to do this public static string MinSearch( string My Time, string MinConTime ) { int MinMinutes; int MinHours; string timestring= "" ; DateTime StartTime = Convert .ToDateTime(MyTime.Substring(0,2)+ ":&q ...Show All

• Visual Studio Nested Designer Surfaces

  Is it possible to nest one design surface within another I want to design a language that enables hierarchical modeling where one design surface has high-level shapes that represent other models which have their own language and design surfaces. Ideally, I'd like the user to be able to double-click on a high-level shape and open the nested design surface, etc. How would I approach this using the DSL tools Point taken. How, then should one model at the meta level I'm thinking of the case where we have a universe of small, scalable modeling languages, each representing a discrete domain and very well suited to a given subject, possibly developed independently. Later, we require a high-level DSL to model meta-domains consisting of ...Show All

• Visual Basic Experimental Learning

  I am making a front-end program for the lame mp3 encoder simply for learning experience. I can get it to handle all the options and output the files perfectly. There are a few questions I still have though. 1. Is there a way to hide the command window that pops up when encoding a file and instead show my own progress window 2. How would I detect the progress of the encoding 3. When I have a list of files to encode the only way I can think of is to encode them all at once. Is there a way to encode them one at a time 4. Is there a way to find the bitrate of a file When I add files to the list i want to show the bitrate of that file. That is what I have for now. Thank you to anyone that can help. As an aside, I have thought about contacting a ...Show All
