' Open the file at the current program's directory. Tip: Instead of just passing "example.txt", you could pass "C:\Users\Sam\example.txt" to specify the absolute directory. When you specify a certain file for Process.Start to open, the default Windows file viewer for the file type will open. It passes one parameter to Process.Start, the directory root. Main: The Main Sub calls the Process.Start Shared method. Tip: Process.Start, found in System.Diagnostics, launches external programs, such as Word, Excel, a web browser-EXE programs. When you run this example the root directory folder will open. It uses Process.Start to open the file manager on your C:\ drive. With GetProcesses we check existing ones.įirst example. Many new tasks become possible, with little extra complexity. With the Process type, from System.Diagnostics, we launch processes directly inside programs.įunctions. A process starts, performs a task and ends. They open Microsoft Word, web browsers and text files. Thanks for this article, very helpful.These VB.NET examples use the Process.Start Function. Do you also use Pathes to combine strings in other places? ?Īnd I’m really sorry for my Enlish. Here you use StringBuilder to combine Pathes. But in all other cases your code is just additional semantic complication. If someone will have an inefficient code then he or she has to profile it first and only after that make any changes (probably which you has written). Well, what you had said is called ‘premature optimization’. If you are going to concatenate a bunch of strings, you should use either string.format or (better) a Stringbuilder. I believe that the shown code is able to solve the problem, but it could be better. Why don’t you use the Path.Combine() instead of StringBuilder.Append()? If it DOES ever happen, at least I’ll know about it! Technically, it should never happen, but where ClickOnce is concerned, a little extra code never hurt anyone. It will be processed if activationData is not nothing and the activationData.Length is 0. Debug.Print( "Item = ", activationData.Length)) String myList = activationData.Split(m圜omma, and separates them into separate entries. This takes each entry and splits it by comma but I'm checking for multiples just in case. I've only ever seen activationData have one entry,
