 | Why do you care if they are quote enclosed? You only do that for strings, not for other data types. |
 | This is a poorly designed method. In line 3 it does a Regex match (IsMatch) then repeats the same match in the very next line (6). Regex is slow, do the matching once and save it. It does this again in lines 9 and 11. Line 20 if nurl is …  |
| | Re: Sort a 2 D Array Sure is, just add the interface IComparable to your Card class, then use the build in Array.Sort. |
| | Re: Error in c# code RemoveAt has no return value (void is not a return value) but you try to return it in your last line. If you want to return and remove the first card, you'll need to place it in a temp variable, remove it from the list, then return the temp variable: …  |

| | I'd use Double.TryParse as you can skip the try/catch exception. |
| | [icode]File.Copy(source, dest, true)[/icode] attempts to overwrite files that already exist (that's what the true part means). It will fail if you can't overwrite the file (it's set to read only, for example). [icode]FileInfo.CopyTo(dest)[/icode] does not overwrite files, so it doesn't generate the same errors. You could change the first to … |

| | Just do your select and order the results by parent category and category. Write a loop, break the results when one of them change. For example, your SQL would be something like[code]SELECT a.Category as Parent, b.Category as Category, c.Food as Food FROM Category a, Category b, Food c WHERE a.id … |

 | Is this a 'commercial' application? If so, get permission from Adobe to bundle their installer with yours. You'll probably need a better installer than the free one you get with VS. If it's an in-house application just instruct them to install adobe reader first. |

| | Re: C# drawing lines This is because the Paint method of pictureBox is only called if it has to redraw the PictureBox. Try doing your two clicks, minimize the form then restore it. Add this to the 'else' part of your MouseClick event: [code]((PictureBox)sender).Refresh();[/code] |
 | Each machine will have its own unique IP address *internal* to the LAN. You can use the internal IP to connect machines *on the same LAN* together. If you are trying to get outside machines to connect to internal machines, you'll have to configure your router to use Port Forwarding, … |

| | No, it's not right. In most cases it will generate an exception (null reference) unless you have a specialized 'leaf' node that implements different code for iPathLength (for example, some implementations of Red-Black trees use a specialized leaf node). |
 | Line 65 in your code requires that you press a key for each time the loop runs. Remove it. |
 | What do you want to do if the number requires more digits, as in '1024 KB'? Setting the number of digits after the decimal is easy, or the minimum number before the decimal. Setting a specific size doesn't always work right. |
| | OleDb doesn't use @ parameters in the SQL statement, you need to replace them with ? so your statement will look like [code]string sql = "UPDATE Orders SET Status=? WHERE OrderID=?";[/code] You can add the parameters just like you have them now, you just have to remember to add them … |
| | Line 28 generates a compiler error and I'm not sure why you even have it there in the first place. Other than that I don't see obvious errors. |
| | Having one form directly change the appearance of another form is bad OO design. It couples the forms tightly. You should pass back information to the form so it can change itself. That said, by default C# controls are private. If you click on the control and look in the … |

| | Re: Nth Root? Because floating point numbers aren't exact (in most cases) you need an error margin, usually called 'epsilon', to let you know when you are done. I'm not sure what formula you are using there, but here's one that works (Note: It requires a power function, otherwise how can you test … |
| | In your first block of code, you declare a new dbData in line 25. Where in your code do you pass that back to the calling code? You don't. So the dbData you declare in line 15 of the last block of code has no relation to the other dbData … |

| | Do you want to store the Intptr (useless) or the information it's pointing at? Storing the value of the pointer doesn't get you anything as, most likely, what you want won't be in the same spot of memory next time. |
