We just started to setup our CI world with Jenkins.

Now we have to create tons of extensions in Java which is really cumbersome as our complete focus is on C#.

I've been using CruiseControl.NET for around 4 years and it does everything a CI server needs to do, and it works well with the .NET Framework as you'd expect. It runs all our builds without any problems, including our deployments.

It's easy to install and configure, and there is large community to help you support it.

Do you have specific requirements?

Today i have a unique requirement which i am going to explain with an example

My String

string s = "aaaabcc";

Now i want to use 2 replace functions at same time. so, answer would be like this:-
OUTPUT

ccccbaa

Till now i don't know how to start as when i write

string s = "aaaabcc";
s = s.Replace("a","c").Replace("c","a");

the answer goes wrong cause last replace function removes the newly added char.
Can anyone help me here any piece of code snippet would be helpful

Thanks in advance

You need to use an interim character that is neither a nor c. Something like:

string s = "aaaabcc";
s = s.Replace("a","#").Replace("c","a").Replace("#","c");

A thing to remember. This is a volunteer site. Just because something is urgent for you doesn't mean that there's any urgency for an answer. Ironically, asking in more than one location dilutes your chance of getting the answer you need in your timeframes.

In other words, when posting a question, show some patience.

While no answer is perfect, I'd be wondering how you are going to recognize it. I'd also like to point out that there is a slight contradiction in "waiting urgently".

If "all the characters are taken", then you'd introduce the concept of an escape-character (or multiple). It was also a bit premature to shout that all characters are taken, as various encodings allow for fewer or more characters.

What do I get if I "fix" it?

It's a "code fragment" that conveys the essence of your question.

Do you know what a "code fragment" is?

Do you know what LINQ is?

Do you know what a "using" statement is used for?

That may be correct but I know I can understand the Replace() structure one hell of a lot easier that your linq solution. I guess it takes a particular mental bent to look at that and have it go 'click' and understand it.

You're right.

Replace() is fine if one is always content just to use the first thing that comes to mind.

If I needed to use something similar in an intensive production situation, I would benchmark "all" scenarios and go with the one that performed best; "bent" or not.

I thought it was an interesting exercise.

But then again, I've also spent a lot of time with LINQ and don't feel the need to dumb myself down because someone else might not get it (or bother trying); after all, it's just a select, a couple of "if's", and a join ...

If performance was an issue I could understand benchmarking the processes, that aside, I always go for the most supportable because the poor sod who has to support the app down the track may not understand the linq but would certainly understand the Replace option.

As a response to a newbies question (which already has a simple solution) it is valid, he may look at that and go Ahhh I get it!

The message from Thomas says that you need to recompile PDFSharp (specifically the PdfSharp.Charting assembly) with the changes he's suggested.

You can find both classes in the folder: PDFsharp\code\PdfSharp.Charting\PdfSharp.Charting.Renderers

Converter is in the file Converter.cs[^]
ChartRendererInfo is in the file RendererInfo.cs[^]

Redraw Coordinates on Cropped Image

Hello. I am placing 4 dots on an image (1280x720) using mouse click. Now I crop this image of size just bigger than these 4 dots (coords). How do I place the 4 coordinates on the cropped image ? Thanks for any pointer.

If you place the 4 dots, then crop the image to a size that is larger than the hypothetical rectangular bounding region enclosing the dots: q.e.d. they are visible on the cropped image.

So the question becomes: what principle/rule/heuristic do you want to apply to re-positioning the dots.

Are there any constraints on where the dots are placed initially, or what their relationship is with each spatially ?

Details, please.
