• Architecture O/R Mapping

  O/R mapping is quite interesting.  I would like to post this question for discussion. I have the following classes: Employee, FullTimeStaff, PartTimeStaff, etc.  FullTimeStaff and PartTimeStaff have many attributes and behaviors in common and also many other unique attributes and behaviors.  So, FullTimeStaff inherits from Employee and PartTimeStaff also inherits from Employee. Do you think it is good to map both FullTimeStaff and PartTimeStaff to a single table called Employee (the table contains an extra field to identity whether he is full time or part time) in the database Converting an object into another is not a good practice. You are not forced to map one object to only one table, a complex object may hav ...Show All

• Visual Studio 2008 (Pre-release) Accessing a WCF service from a ASP.Net Web application

  We have used web services before and are trying to migrate to WCF. I am trying to use an ASP.Net application to communicate with a WCF service using a hello world example.

• Visual Studio Express Editions Formatting output in a textbox/label

  Hi I'm writing a program that basically calculates two numbers entered via text boxes then outputs to a label on the form. Sometimes I get a number with three decimal places. How do I change this to just show 2 decimal places Also, I have six rows of three columns. Is there an easier way of assigning a value to these similar to using an array For example, I currently have to assign a value to an array for (int a = 0; a < 5; a++) { arrayvalue[ a ] = a; } Then output individually to each textbox textbox1.Text = arrayvalue[0]; textbox2.Text = arrayvalue[1]; textbox3.Text = arrayvalue[2]; etc Can this be changed to for (int b=0; b < 5; b++) { textbox[ b ].Text = arrayvalue[ b ]; } Or am I just being super lazy lol!

• Smart Device Development Hanging up an active phone call using Managed Code

  My wife and I have a telephone plan which provides free talk time for the first ten minutes of each call between our two phones. I recently discovered the State and Notification Broker elements in Windows Mobile 5.0. From these, I can detect the id of an incoming caller and spawn a new thread which counts out ten minutes. My objective is thus to automatically end a call when it approaches ten minutes and thus assure conversations between my wife and I are essentially free (call-connection charges notwithstanding). However, I cannot figure out how to programmatically disconnect the line. Does anyone know how to do this Thanks. The following thread sould answer your question: http://forums.microsof ...Show All

• Visual Studio Express Editions releasing resources question

  Hi, i'm moving an Image object around with the MouseMove event,  and I have a Graphics object which draws the image in a Rectangle object.  Do I need to release resources - such as the dispose() method My pc crashed a couple of times recently, and I wondered if this had anything to do with it.    Hi, It's better if you dont override the onpaint event of the form, use form.paint instead (so it will not call the base.onpaint event). But it's not the cause . It seems that you want to drag the pic follow the mouse, right There is a more elegant implementation similar to it: http://www.java2s.com/Code/CSharp/GUI-Windows-Form/DraganddropthePictureBox.htm ...Show All

• Visual C# big array and threading

  i'm developing a software to read values from a USB unit thats connected through a virtual COM port. I have an static array with size of 50000. I store my specialized object containing seven variables in this array. This array is filled with values as I make my "thing" with my external unit. Now the problem is that it's really slow to collect values. My readings come in with a speed of about 1 value each 2 milliseconds. I wrote my object as a struct to speed things up. Would it help to make my reading in a separate thread from my app JockeOlsson wrote: I have an static array with size of 50000.

• Visual Studio Team System Branching - how to prevent merging into older branches?

  Here's the situation that we ran into.... We have two release versions: 5.0 and 6.0 5.0 is in production and 6.0 is in dev currently. In the meantime there is a call for a maintenance release off 5.0, which we call 5.1. Obviously, we want these changes merged into 6.0. But, we don't want these changes merged into 5.0, because then 5.0 would not be representative of its original form. So....how do we go about merging the changes from 5.1 to 6.0 The only option I see so far is baseless merging from 5.1 to 6.0. Since this scenario is pretty common we will be doing a lot of baseless merges. I would like to stay away from this option if possible since it seems more complex and something that could result in more errors. Any thoughts on how to ...Show All
