• Architecture workflow engine and rule engine performance

  Please give me your criticakl comments on performance degradation issues arising out of usage ofworkflow and rule engine vis a vis increase in scalability and agility I think that at the end of the day it doesn't matter what performance degradation (if any) you have - it only matters does the architectural appraoch of workflows and/or rule engine fits your solution. for example, for business rules do you have complex business rules does your business rules change frequently, do you have a lot of business rules . Once you decide this is the right direction - you need to evaluate the performance and scala ...Show All

• .NET Development Type.GetMethod is incredibly slower in .Net 2.0

  My application uses scripts that are user provided and generated at run-time. These text scripts and appended into a class, compiled with a code provider and then invoked by reflection. This works great with .Net 1.1 but with .Net 2.0 the Type.GetMethod used to aquire a MethodInfo for invoking a script is performing significantly worse. What takes 0.3 seconds in 1.1 takes 20 seconds in 2.0. This is quite unwanted. Why is this and is there a better approach to avoid this delay Thanks in advance, Duncan See below for an example that you can execute in 1.1. and 2.0 to see the difference yourself. It first creates the code provider, generates ...Show All

• SQL Server Expressions not evaluating values???

  Hi, I use an expression in a column text box to dynamically compute the column title. The problem must have something linked to the way expressions generally works. I do not understand it clearly. In this example, I use a SWITCH function to test the numerical value of a 1 row 1 column dataset. The problem is that I can test the number only if it is lower or equal to the number in the dataset. if I test a number greater than the number in the dataset, I get an error. How can I get this test to work if the value tested is greater than the value in the dataset Thanks Philippe Bellow is the code. ------------ ...Show All

• Visual FoxPro cannot update cursor < > since it is read-only

  I am getting this error message at RUNTIME ONLY in startMode = 4. In interactive mode (starMode = 0) everything works fine. This message comes from a secondary form that I use to select email addresses. They are stored in a table with a few fields. I dedicated one of them as a markup field meaning that if that address is selected in a combobox it is marked, the table is updated as TABLEUPDATE (1). I mean, it is supposed to be updated. It is not . Instead I get a series of error messages related to each address selected (main address, CC, BCC, etc). I do not understand the message because there is no cursor. It is a table. Again, it appear ...Show All

• Windows Forms Manually wrap a string

  How do I manually wrap a string I want to popup a help text as a ToolTip on a TextBox, but I do not know how long this string is in advance and as the ToolTip does not have a maximum width with autowrap it might look pretty ugly to have an 800 pixel wide ToolTip with one line. So it seems that I have to break the string myself. How do I do this, if I want to break it after a full word every, e.g. 250 pixel One way I guess is to create a Graphic object from an empty Bitmap, append word by word to the string and measure it each time until it fits, but that sounds pretty unefficient to me. Is there a build in function I did overlook ...Show All

• Windows Forms Accessing a control from outside the form class (in form.h)

  Hi, Hopefully someone knows a little programming trick here. :-) A USB device connected to my computer periodically executes a function in a provided DLL file which in turn executes a function in my program. Within my function, I'd like to write some text to textBox1 in the form. Since the function is outside the form class in the form.h file, I have to pass the textbox in as an argument. HOWEVER..... I cannot do this because I cannot edit the parameters of my function (they are dictated by the DLL file). So how can I access this textbox from a function outside the form's class without passing it into the function as an argument ------------ ...Show All

• Visual Basic Newbie Database Question

  This is a very basic question, but I've wasted a few hours trying to figure it out already, so I'm groveling for help. I'm looking for basic code to help me open a database, read some of the contents into variables, and that's it for now (close the database). The database in question is a flat table in mdb format; 8 columns, 15 rows - each row is a record with a name (p01, p02, etc) and seven associated strings - pretty primitive. The 1st column is the record name. I've gotten as far as associating the file with my project, but can't find the trick on how to open it and read what's in it. The code should: 1) Open the file ("CCUG PreOp.mdb") ...Show All
