• Architecture Modular application development

  Hello... Being relatively new to large scale applicaton development I would like to ask if a) there is a simple way or b) there is a preferred way; to developing a modular application. What I mean by this is that I would like to create an base application which will be along the lines of a point-of-sale app. However, users can opt for (and pay extra for naturally!) additional "modules". For example, a reporting module, a stock control module, a restaurant module etc. Rather than simply creating separate application that interact, I wondered if VS2005 or the VB.NET 2.0 platform in general had a "perfect" solution to this hidden somewhere. Most importantly, the application needs the ability to be able to add a ...Show All

  Hi, In my data flow taks, The Source data is coming from AS400 has 4 columns, I need to achieve the followings and require your help. 1. Generate a new column which will be combination of concating these 4 columns. 2. Need to add an extra row for Header & Footer. Please Help. Ahhh..I didn't think about that. Sorry. There is no way to guarantee the order. I've thought of another way actually. Use a single script component transform to add the header and footer. It will have to be an asynchronous component.

• Visual C# how to return null from a constructor

  say, i a m trying to do something like: class something something(streamreader){ if (wrong format or end of file) caller receives null as result else build object from what has been read in file } i tried 'return null', but it says it can not do that since a constructor is 'void', so i can not place a return sentence. i'm not sure something like this.dispose would retunr a null, since the 'dispose' may be asynchronous (or something) i have the next alternative class something blah blah somehting(string) (build object from string, check if string==null or wrong format before calling) static bool checkformat(string) check to see if string is adecuate to build somet ...Show All

• Windows Forms Windows installer launch condition

  Hi Guys, I am trying to create a setup and deployment project in VS 2005 for a windows form project. A couple of dependencies for my application are - 1) .NET framework 2) ActiveState Perl 5.8.8 I have been able to successfully add the .NET 2.0 framework check to the launch condition. I've also added the Active Perl check but its not working right. I mean, I get a "perl not found" error even on systems where the perl is installed. How should I correct this behavior Its probably something in the Condition check that I'm messing up. Here are the properties I have for perl launch check - (Name) ActiveState Perl Condition Installed InstalllUrl <url> Message Perl could not be found. Please install ...Show All

• SQL Server Row height issue on export to Excel

  Hi all, I've been having some problems with a report on export to Excel. I have four tables, contained within a rectangle at the top of the report, followed by a second page of tables dynamically generated by the data being fed into the report. On export to Excel, the top sections of tables appear to export with a fixed row height that does not show all of the string contained within the cell. I've had similar issues before with "title" textboxes, but these are usually easily solved by expanding the height of the box within the report. In this case, this hasn't worked! Any idea Regards, Jon If you have other tables at the same horizontal level, or other r ...Show All

• Visual Studio Tools for Office C++ retrieving data from database.

  Hi, How come when I use C++ to read data from Access database, it only let me read up to 255 chars instead of all the text I have in that specific cell.

• Game Technologies: DirectX, XNA, XACT, etc. Raytracing with DirectX

  Can someone please recommend a few good resources for creating some basic ray tracing engine code for someone familiar with DX9 raster graphics. Specifically something with coding examples and how/where/when to use shaders in conjunction with ray tracing. Also, something that has been created/written within the past 2 years, not things from pre-DX8.1 days. Thanks. In general ray tracing and DX raster graphic have no overlap or any connection. There are some folk making real time ray tracing code that uses a lot of the modern culling techniques to speed things up and I wouldn't be surprised to find people using the GPU to do some of the processing.
