View 8 RepliesThe issue, is that I'm developing an app that won't be installed and will be used on a bunch of different PCs. The app is free, but uses some 3rd party tools and code, so the user must be aware of the licensing agreement for those tools.
Since it will be used on a bunch of PCs, I don't want the end user to have to accept this license agreement a million times.
Is there any way I accomplish this with a local resource of some sort?I was thinking I could add a license file that should be moved around with the executable, and that could contain a license agreement code, then i could prevent the app from being used without that file.

View 2 RepliesI want to check each of the strings in an array (currently in a hashtable, but that shouldn't necessarily matter right?) with the user's input, if the words in each of them match. This might have sounded a little tricky so let me elaborate.
Problem: Comparing an input string with a collection of strings, and know which string in the collection matches the input string the most - based on words. What I'm trying to do here is a chatbot that works with keywords. For example, in the bot script, you could find "HOW ARE YOU" and the response "I am fine." If the user then sends input to this bot, it could look like this: [Code] This may not sound like a tricky thing, but the tricky part comes when I want to know which of the strings (e.g. "HOW ARE YOU") match the input string the most, based on the words.

View 1 RepliesIs there anyway to check if a Control has been validated yet?I have some code that I want to run when the Selected of a TabControl fires off.The thing is, that I have TabPages added to the TabControl at the beginning of runtime, which then triggers the Selected event before the control is completely existent, which means the Sub I have that also happens to reference the control during that event errors out because there is technically not an instance of the control completely finished building so it says I don't have a correct reference set to that object.So basically, I want to be able to check in the Sub if the control has been Validated, or maybe even created or whatever is going on.

Now Here's my confusion. And i spotted at least one other person on here who was asking the same thing about this.But got no real clear answer that i could see. as a test to compare i tried his suggestion and loaded the same listview up in both a vb6 app and a vb.net app..The list i used was quit large so the comparison would be very through..my list was in the 80,000 lines range tho..yeah talk about overkill The vb6 app checked/unchecked the items within a matter of milliseconds..the vb.net took an extremely long time tho..well not extreme but was very noticeably slower about doing the loops.
