    parameter must be positive and < height

    We already know that the exception is thrown. The debugger tells you exactly what line it is thrown on, which you haven't told us. When the exception is thrown, you can use the debugger to determine the values of all your variables and any other relevant expressions, which you clearly haven't...

    parameter must be positive and < height

    You don't need to make vague guesses. You can determine specifics by debugging. You're not going to get far if you refuse to debug your code.

    parameter must be positive and < height

    So did you investigate the problem? What line did it occur on? The error message is telling what parameter was the issue and why it was an issue. Did you look to see what value was actually being used and examine the code to see why it isn't valid? You can actually investigate the issue for...

    Beginner stuck write to excel

    Figure what out? What line or lines don't do what you expect them to? What do you expect that line or lines to do and what do they actually do?

    Beginner stuck write to excel

    Just dumping a wad of code and expecting us to trawl through it in the hope of finding some nebulous issue is not the best way to go about things. Some people will take the time but I am certainly not one of them. If you've written that code then you obviously have a pretty good idea of what...

    Here's a quote from the page you linked to: Here's a quote from your post: Based on that, why are you writing any code to do this at all?

    Question Voice Recognition

    You need to look at the InnerException to see what the exception was that was thrown by the method invoked on the other thread.

    Question Voice Recognition

    Firstly, I have formatted your code for you, which you need to do yourself. As you can see, it is eminently more readable. If you've ever used a text editor then you know how to edit the text it contains. Secondly, you need to be far more specific about the issue. Dumping all your code and...

    Question dnsapi.dll and DnsQuery() in VB.NET

    You seem to have missed this bit: Without having looked at that doco, you would presumably call the appropriate function(s) in the same way you do other Windows API functions, i.e. using Platform Invoke (pinvoke).

    Question Determine which cells are currency in Excel

    Are you looking to do this via Office Interop, i.e. effectively remote controlling an instance of Excel, or simply by working with the data directly?

    Installation Tutorial for SFML.Net 2.5 with Visual Studio 2019 and VB

    Oops, got the words slightly confused but pretty close for not having seen the show for 30 years. I'm surprised that you're using the name but didn't recognise the theme song.

    Question How to use ACS ACR125U-M1 ?

    If what you have shown is your application then you need to show us what you've actually done so far that is relevant to the issue. If it's not your app then I don;t see that this is even a VB.NET question because you already have some other tool telling you that it's not connected so you need...

    Account question

    Just opened your member profile and checked the moderator tools and the actual name is one thing that can't be changed. An admin may be able to do so though, so we'll have to wait for Neal and see what he can do.

    Question Help With A Code For ComboBox & ListBox

    Detecting that an item has been selected in a ComboBox and which item it is will be the same no matter what you want to do about it. Populating a ListBox with items will be the same no matter when you want to do it. Two simple problems to solve and then just put the solutions together. That...
