I'm trying to send a key stroke to one application, through PostMessage. I am using too Spy++ to try to understand how to send the message, as I do not fully understand its inner workings. In this picture, the first item(selected item) was made with an actual key stroke made by myself. The one with a red elipse around it(below) was made with the following code:

I guess it must have something to do with the last PostMessage() parameter, but I can't figure out how it really works. I can see in the original key stroke the ScanCode = 48, and in mine its 0, and also fExtended is 1 and in mine is 0. How can I make it look the same? edit: Here is the msdn link. [URL].aspx I cannot understand the last parameter's working, if anyone does..
give me a link to an Example on SendMessage/PostMessage? (I want to use SendMessage/PostMessage to send Strings)

The gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help
Is it possible to set a variable in my custom class for Private Read/Write access and Public Readonly access without creating Properties with Get and Set?

What I want is, when I click to use the calculator, the background process is not stop. I only want we cannot touch the form at the back, I meant we cannot click the function at the back form untill the calculator is close. The calculator also should locate at the top of the form and cannot be minimized.

The picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.
