Process.Start will do that for you. In general, www.pinvoke.net is the place to find out how to call Win32 APIs

If you want to call a specific function.. u can call as

<br />
[DllImport("USER32.DLL")]<br />
public static extern int SendMessage(int hwnd, int msg, int character, String text);<br />
<br />

I am writting software for my company in which the program needs to generate an Excel file without using excel. I've figured that part out by using the XML format for excel. However, I was wondering if there was a way to pring the files (preferrably sheet by sheet) without having excel installed? Or is there a way to convert the XLS files into a PDF? Any help in the right direction would be appreciated.

AFAIK, all the ways to read or work with an XLS files require Excel installed

don't just add framework into your project, right click on setup project, select properties, click prerequisites and tick .net framework 2.0 and select install from the same location as my application option too. now build your project

after building the setup project make sure you have .net framework redistributable in a folder inside your setup's release folder. if it is there then you are doing right. when you double click setup it will say the following prerequisites are not installed in your computer and will install when you press ok. thats the right way.

when you added your project output (the exe file from your program) visual studio will automatically add .net framework to your detected dependencies folder in solution explorer. make sure it detects correct.

How should I add an exe into my active project , When the same is demanding a COM component.
I mean can i add an exe into my active project????????????????

when you create setup project first open the project you need to create setup for. then from file add new project and then other project types and setup project. give the name setup and select add to current solution (you should not create a new solution). when setup project is loaded, on filesystem editor right click application folder and select add -> project output and select primary project output.
this will detect dot net version and prerequisites automatically. now you won't have to select dot net manually

How visual studio will automatically add .net framework to detected dependencies folder in solution explorer.
I have - in the prerequisite - checked the download prerequisites from the same location as my application.
I can't add the exe into the active project.because it is the COM component , dll not the exe which gets added into the references
Now what i have to do in addition to these to make the visual studio automatically add .net framework to detected dependencies folder in solution explorer

so you are using a .net setup project for deploying a non .net project ?
i didn't understand. don't you have a sing exe or dll created in .net 2.0 in your project ?
