Last week a co worker of mine who wanted to remain anonymous, ran into the weirdest problem. She tried to use the “find in files” option in Visual Studio 2005 and even though the searched expression was out there in one of the files, she got the following result: “No files were found to look in. Find was stopped in progress.”
You can close Visual Studio, restart your computer or jump three times on one leg, but the problem remains. This is a very strange and odd bug, but fortunately there is a solution: press…
Have you ever tried to create a DataTemplate for a Generic Class? During last week I had to battle this issue and it is allot more complicated then it sounds. As far as I can tell Creating DataTemplates for Generic classes is impossible. There is some kind of workaround but it is not all that good. OK lets get down to business. This is the class we are trying to template
The sixth of the series of programming job interview challenge is out. Other then commenting the solution, I remind you that you can post the solution on your blog and get a link next week!
Here is the solution to the previous challenge:
Two-way merge sort (External Sorting) : The idea is breaking the big file into subfiles, sorting them and than merging them back together. In the first pass read one page at a time, the records in the page are sorted (quicksort for example) and the page is written back to disk. in subsequent passes, each pair of sorted output from the previous pass are read and merged to produce sorted subfile twice as long:
1. Read each page, Sort it, Write it back
2. while more than one sorted subfile:
while subfiles from previous pass left to merge:
- Choose next two subfiles from previous pass
- Read each subfile into a memory page (one page at a time)
- Merge the subfiles (remember each of them is already sorted), write output to a memory page
- Write output page to disk when needed.
