Developer's Corner / Re: searching the web (in particular, Amazon.com) from c# program

« Last post by kyrathaba on July 04, 2014, 07:56 AM »

I'm downloading the Amazon Web Services SDK, but if there's a quick and dirty way of getting what I want, I'd rather not have to delve into all of that.

Developer's Corner / searching the web (in particular, Amazon.com) from c# program

« Last post by kyrathaba on July 04, 2014, 07:54 AM »

Does anyone know of a free class or control I can use that abstracts away the nitty-gritty details of the search implementation and will simply allow me to search for eBook titles on Amazon.com? Ideally, user could enter a search string in my program (e.g., "Kyrathaba Rising"), and the program would then search Amazon.com for that title.

Aha. I already had 2.0.  I just went to the Application tab under Project Properties and specified 2.0 instead of 4.5.

Is it possible to install 2.0 alongside 4.5 and then tell Visual Studio Express which version to use in a given project?

Is there a relatively painless way to downgrade,  or would I have to manually uninstall 4.5, download 2.0, and install it?

I'm trying to collaborate with a friend on an idea for an app. Im building on a Win 7 machine using C# on top of .Net 4.5. He's running WinXP and gets a Not a valid win32 app message when he tries to run my program. Even when I use the x86 build configuration. I think it's because .Net 4.5 is for Vista forward (per Stackoverflow.com). Any solution so he can run my progs?

That looks workable,  Ren. But any regex would need to capture and replace whitespace before,  among and after the numbers: "9. 07" becomes "9.07", and " 7   6 . 04" becomes "76.04"

For my purposes, an improperly formatted decimal number is any substring which, when any interleaved whitespace or other non-decimal, non alphanumeric characters are removed, forms a decimal number.

"abc3.-04xta" becomes "abc3.04xta"

"abc6/. 7?8xta" becomes "abc6.78xta"

Developer's Corner / Need help with some string manip in C#

« Last post by kyrathaba on June 21, 2014, 05:54 PM »

Maybe someone can help me with this. I'm needing C# code that reliably does the following: given a string of characters, it returns a substring of characters. If the substring has an improperly formatted decimal number, that is the returned substring. Otherwise it returns a zero-length string.

So, as examples, it would detect the following in string "abc3. 04xta": -> returns "3. 04"

And for this string: "3bcd4 0.  25z10": returns "4 0.  25"

What I'm ultimately wanting is for the code to do a string.replace( ) that fixes the misformatting:

"abc3. 04xtra" becomes "abc3.04xtra", and "3bcd4 0.  25z10" becomes "3bcd40.25z10".

I know regular expressions is probably the way to go, but I'm having trouble getting my head around them.

The method I'd like would either return the poorly formatted "decimal number" substring; or, optionally,
it could fix the formatting in that substring and replace all occurrences in the larger string.

The end result is that it would turn this sentence...

"The bread was $3 .49, and it had always been $2 .15 before."

...into the following...

"The bread was $3.49, and it had always been $2.15 before."

Developer's Corner / Small utility class with methods for manipulating C# forms, controls, and fonts.

« Last post by kyrathaba on June 01, 2014, 05:44 PM »

Four methods in static class MyForms.cs
(1) center and size a form
(2) center a control on a form
(3) center a control horizontally only on a form
(4) change the font and font style of a control

Sample project included as attachment.

I'm posting a slightly modified version of the project that adds a demonstration of creating a nested subdirectory and writing a file to it. This version does everything the project in the OP does, plus this extra functionality. See attachment.

The attached zip file can be extracted and then the project can be run with Visual Studio (Express or higher editions).
The text file just lists the method signature for the six methods of the static class, and comments them.
As demonstrated in the project, use a "using" statement to reference my namespace.

Demonstrates:
(1) converting file size (number of bytes) to string description, e.g., "7.405 Kb"
(2) reading a file into an array of type byte
(3) writing string data to a filepath
(4) returning number of files in given directory matching a given pattern
(5) returning total size of those pattern-matched files, in bytes
(6) obtaining the directory of the currently executing assembly for a C# console application
