• Visual C# Design question: collection of collections

  Hello, I need to implement an investment portfolio data structure. I'm thinking that the basic unit is going to be a transaction (ex: buy 10 shares of IBM). Multiple transactions will be combined in a position (ex: buy 10 shares of IBM on September 1st to open the position, and sell 10 shares of IBM on September 30th to close the position). Multiple positions are going to be grouped in an account. Multiple accounts are going to be grouped in a portfolio. The restrictions on positions is that the same account can not hold more than one position of the same side (long/short) in the same instrument at the same time. The way I plan to approach this problem is with a bunch of nested collections. An IAccount will have an ICollection& ...Show All

• Smart Device Development Why Can not I connect the WM5.0 device by the remote process viewer and remote heap walker?

  For the first time, I installed the Visual studio 2005 professional Edition (VS2005) first and the the Windows CE 5.0 with Platform builder 5.0 later. I find I can connect the WM5.0 device with the remote process viewer and remote heap walker provided by VS2005 and all data can be obtained successfully. However, when I reinstalled my system by installing the Windows CE 5.0 with platform builder first and VS2005 Professional Edition later, I find I can not connect the WM5.0 devices with the remote process viewer and remote heap walker (the other tools are OK) provided by VS2005 although the Activesyn shows that the WM5.0 is conncected correctly. Anyway, all the remote tools provided by VS2005 can connect with the emulator. By the remo ...Show All

• Visual Studio rsNone - Query execution failed for data set ...

  I have created a reporting services report in Visual Studio. It uses a SQL Server 2005 stored procedure which creates a #temptable. The primary report works fine, but the subreport does not. It yields an rsNone error. This subreport executes a simple query of the #temptable. Does the #temptable persist into the subreport Sub reports are considered a new report in Reporting Services. You should create a seperate report which should be based on different result set. You can have parameters in the sub report in order to filter the data based on values from the main report. From my understanding...I don't think a temp table from the main report can be accessed in the sub report. ...Show All

• .NET Development Managed Heap Virtual Memory

  Can someone point me to a reference which describes the amount of virtual memory allocated to the managed heap on startup I'm under the impression this is hardware dependent (ie..# of processors and size of registers, 32/64 bit) but wondered if this is documented somewhere. Hi, Every process (no matter if is .NET) starts with a default working set of minimum 50 pages. This is configurable using the function "SetProcessWorkingetSize". The size it will depend of the page size in your system, upon the page size is based on hardware you still have an option on the OS. You can select using a small page (default) or Large Page Size. You can change this setting changing the registry option:  Local Machine\System\CurrentControlSet ...Show All

• Community Chat Native C++ cross thread call framework

  If you're a C++ developer, with an interest for threads and interlocking, I'd be greatful for any input (be it comments, suggestions, criticism) on a generic framework I've been working on. I wrote a quick article about it, and included full source code + examples at Codeproject: http://www.codeproject.com/useritems/threadsynch.asp . I find that not too many seem to share my passion for that specific subject, so by asking here, I hope some thoughts are presented (or perhaps provoked). The very reason for me to put the framework onto Codeproject, was to enhance it through feedback and collaboration with other devs. Anyway, as I said: all thoughts are welcome. Should I include some diagrams to better explain how the framework does it's ...Show All

• SQL Server Query criteria / parameter for a whole project

  I have a large collection of 'projects', i.e., RS reports for each of our customers. Each project is effectivley a library of maybe up to 15 reports. They are usually modified slightly according to the customer's requirements. Most of the reports use a variery of SQL tables / views and to ensure the customer only sees theor data. I am currently changing the query criteria for each report in the project each time I deply a new library / set. This is time consuming and open to the risk that I mis-key the criteria for one or more report. The criteria is always the customer's account number and is common across most of the database tables. E.g: WHERE (LIVE_INVOICESUMMARY_CRREPONLY.IS_SUCODE = 'DH166'... Is there any easy way to set this ...Show All

• Visual Studio 2008 (Pre-release) January Orcas CTP

  Hi! I have download and installed January Orcas CTP on virtuell server and now I can start Visual Studio Orcas 9.0, but can not find any Linq project to start playing. I am a first timer about Linq. I checked and there is a version 3.5 Net framefork installed under Windows. Regards The official 'Orcas' CTPs do not have LINQ project templates. Those templates existed in the eariler LINQ-only CTP's to help you start a project that targetted the correct compiler. With the Orcas CTP, the main compiler understands LINQ. All you need to do is include the correct DLL's and namespaces to get going. For LINQ standard-query-operators you need to reference the new System.Core.dll and use the System.Li ...Show All

• Visual Basic Unsigned Arithmetic and overflows

  I've had this discussion before with unint64s. Setting what would normally be the sign bit causes an overflow. Now I'm seeing this in unint32s. Dim a As UInt32 = System.Drawing.Color.Black.ToArgb will cause and overflow. Dim a as Uint32 = now.ticks and &hFFFFFFFF will cause an overflow depending in the time. This should not be. What it means effectively is the UInt32 is actually UInt31. Well, you get the same behavior as long as you tell the compiler what type the constants are. It's not big deal to add an UI suffix after all. ...Show All
