• Visual Studio Determine Number of Pages on Report

  I have a custom print/export feature on my webform instead of the built in ReportViewer controls. This allows me to print/export with MS AJAX. The CRV outputs javascirpt in the page load event which doesn't play well with MS AJAX. My code allows the user to optionally input FirstPage and LastPage to print. If FirstPage is blank then default to 1 If LastPage is blank then default to N. I can't figure out how to get the number of pages out of CR. I tried setting N to zero (0), but that seemed to output the entire report no matter what the value of FirstPage is. Any ideas on determining the CR page count. I did see this post http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=560381&SiteID=1 but this doesn't work with my report ...Show All

• Visual C++ Project does not detect code changes in referenced project

  Hi, I have a C# application that has a reference to a managed C++ assembly/project, which contains some managed and some unmanaged C++. At one of my computers, suddenly the C# project no longer detects code-changes in the C++ project, meaning that the dll-files copied to the bin-folder of the C# application is out of date. Facts: Set "Copy Local = true" on the referenced assembly I tested on a different computer, and there this was not a problem - the C++ assembly was properly copied to the target bin-folder of the C# application. If I do "Rebuild solution", the C++ assembly is properly updated in the target bin folder. Visual Studio detects that code changes has been performed, but the "parent" project does not. ...Show All

• SQL Server DATAMINING tasks

  what are the different data mining tasks........... The most common basic data mining tasks (supported by SQL Server 2005) are classification, regression, clustering, forecasting, association analysis, correlation analysis. All tasks act as blocks in solving a really large set of business problems. A few starting points: - http://www.microsoft.com/sql/technologies/dm/default.mspx -- The tutorial and the Webcast ("Introduction to Data Mining in SQL Server 2005") provide a good description of what data mining tasks are supported in SQL Server, plus details on the tools - http:// www.sqlserverdatamining.com -- lots of information, tutorials etc. ...Show All

• Visual Studio 2008 (Pre-release) how to bind to a dictionary (or something like that)

  I've got a dictionary<String,Object> and want to bind a xaml object to the key of the dictionary so it shows the corresponding value. So far I only found ways to bind to get/set accessors, or to attached DependencyProperties, but can't find a way to bind to the key of a dictionary. Is there any way to bind to something like this thanks, Sam You can create bindings where the path is based on indexers into a collection. In a string format you can represent the index delimiters as [ key ]. See documentation for Binding.Path . To create a binding in code that could take an arbitrary key you could write a little utility like this: public Binding MakeIndexBindingFromPath(string keynam ...Show All

• .NET Development fast ping

     Hi,    I need to write a fast ping program to ping class C & D IP addresses. I have written a piece of code to open a socket, connect to it and receive data from it with a timeout. This is fast enough for a few IP addresses but  I would need to ping 255x255 IP's. I have put this code on a separate thread which calls an asynchronous method to loop over the IPs. This is taking a minute for each set of class D IP's. How do I make it run faster Thanks  PS: I am using the 1.1 framework this .clientSocket.Shutdown( SocketShutdown .Both); this .clientSocket.Disconnect( true ); // True means Reuse //Dont Call Socket.Close otherwise it ...Show All

• Software Development for Windows Vista ConnectDirect() failing without calling CheckMediaType

  Greetings all. I'm just getting into DirectShow programming, so I apologize if this is a stupid question or anything, and I also apologize for my incessant wordiness. I'm trying to make a renderer filter. For my reference, I'm looking at the DX9 Texture Renderer sample. The sample was surprisingly buggy, but after fixing it up I got it to compile and render onto that lovely cylinder. After taking it apart to find out how I could implement something similar in my own program, I found that it worked by just adding the source filter to the graph, adding the custom renderer, and just calling Connect() on the pins, letting the Graph Builder stick in whatever filters it felt was necessary. This is not acceptable to me, because it seems it always ...Show All

• Visual Studio 2008 (Pre-release) What purpose is the 'let' keyword in a query expression

Do you have an example use. Troy. OK, I think I get it; it's for efficiency. It lets you do an intermediate projection so that it can be used throughout the rest of the query.

• Smart Device Development Winsock and timeout under WM5

  Hi everyone, My application connects to a server using GPRS. Since the application is running in the backgroung, I want to ensure that whenever the user presses the red key (stopping GPRS connection), the appli connects again. I could achieve that but the thing is that now, my server is asked to reply as late as possible (to minimize GPRS traffic). When a request is sent, the appli is waiting for an answer, if I press red button at that time, the application won't connect again. I again there is a failure in the timeout handling in the winsock. I use the command : setsockopt(this->m_iSocket , SOL_SOCKET , SO_RCVTIMEO , (char*)&iTimeOut , sizeof(int) ); to set the timeout, but it seems reading MSDN that SO_RCVTIMEOUT option is not i ...Show All

• Smart Device Development Device ID Data Type

  Hi All, I want to be able to uniquely identify a mobile device. I've discovered that devices have a Device ID but is only accessible via the Win API through PInvoke() calls. The article I found is here: http://msdn2.microsoft.com/en-us/library/ms172516.aspx PInvoking is not a problem for me. I actually found this article through a message board where someone actually had problems using it. 1) Is this article up to date and compatible with WM 5.0 devices Most Importantly 2) Is the device ID a GUID Or is it something else The article indicates it converts the final result into a string not a native GUID. This doesn't actually mean that the string doesn't contain a GUID though. I haven't run it through yet to see, but I do ...Show All
