Cela est normal avec windows10 pour une application universelle car c'est le système d'exploitation qui gère la permission de l'utilisateur OK bien !!! Mais mon application est automatiquement compatible Windows 8.x lors de la soumission au store et il échoue puisque avec 8.x c'est le programmeur qui gère l'autorisation avec le code:
Var accessStatus = await Geolocator.RequestAccessAsync (); demande d'accès
Switch (accessStatus) // test d'accèsStatus
Dans visual studio 2015 aucune définition dans geolocator pour requestaccessasync (), (seulement "égal" et "égal de référence") quelqu'un saurait comment contourner ce problème je cherche depuis une semaine.
je doit donc tester si ce n'est pas windows10 (ça d'accord) et dans ce cas demander l'autorisation d'accéder à la geolocalisation à l'utilisateur qui devrait se faire avec le code çi dessus mais c'est impossible je suis donc dans une belle impasse.
je vous souhaite à tous de bonnes fêtes.
bonnes fêtes à tous

This is an English language site, and we can only answer questions in English.
Please try using Google Translate:
This is normal with windows10 for a universal application because it is the operating system that manages the permission of the user OK well !!! But my application is automatically compatible Windows 8.x when submitting to the store and it fails since with 8.x it is the programmer who manages the authorization with the code:
Var accessStatus = await Geolocator.RequestAccessAsync (); Request for access
Switch (accessStatus) // access testStatus
In Visual Studio 2015 no definition in geolocator for requestaccessasync (), (only "equal" and "reference equal") someone would know how to get around this problem I've been looking for a week.
I have to test if it is not windows10 (that agrees) and in this case ask permission to access the geolocation to the user who should be done with the code above but it is impossible I I am therefore in a beautiful dead end.
I wish you all a happy holiday.
Happy Holidays to all
But it doesn't make a lot of sense to me even translated - it looks like an attempt at an answer in parts, but to what I am not sure...

La langue de ce site est l'Anglais, donc les questions doivent être en Anglais.
Je ne vois pas bien quelle est la question.

Specified cast is not valid.
|
|
|
|
|
So the Value of that cell cannot be cast to a bool type. You need to investigate why.
|
|
|
|
|
We can't tell without knowing what the error is - but it's most likely that this.invoiceNO.Index is trying to reference a cell that doesn't exist - it would be very unusual to have a table which held all invoices as vertical columns: normally it would be the row that is indexed to supply all the information for a single invoice, not the column:
Columns -> Invoice No Customer Date ItemsCost VAT TotalInvoiced
Rows 1001 Smiths 2016/12/14 102.37 20.47 122.84
| 1002 Johnson 2016/12/15 1247.99 ...
V 1003 Smiths 2016/12/15 742.65 ...
...
So use the debugger and see what value you have, and check the actual column data against that.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
|
|
|
|
|
this is debugger error(Specified cast is not valid.)
|
|
|
|
|
So use the debugger to look at the value of that cell and find out what type of data it contains. When you know that, you can start looking at why it isn't a boolean value.
We can't do that for you: we can't run your code, and don't have your data which fills the table if we could!

Are you clinically insane?
You would allow total strangers you never met to remotely control your PC?
Have you any idea what some of them might do?
Have you ever heard of ransomware?
If you have that enabled, disable it immediately!
Use the debugger.
Look at the cell content. It should tell you a lot.

We are in a community to help each other, but you have no idea who people are, and what they are going to do. This is the real world, and leaving your machine open for total strangers to access and do whatever they want - and if you give them access to VS that's exactly what they can do - is not "asking for trouble" it's inviting it indoors, giving it a beer, and telling it where you keep your credit cards! 
Be realistic and honest: you know how to use the debugger, don't you? (If you don't, then say so and we'll try to get you started. But not telling us relevant information is just wasting your own time, as well as ours)
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

i get my issue....
i need to get the value from DataGridView that was selected into array.
can you write to me example code.

Sorry, but I don't understand what you said: remember I only get exactly what you type to work from.
Can you explain in more detail, perhaps?

i need code for get selected column value from datagridview into array list
//foreach (DataGridViewRow row in this.dataGridView1.Rows)
//{
// if ((((bool)(row.Cells[this.invoiceNO.Index].Value)) == true))
// {
// a.Add(row.Cells[this.invoiceNO.Index].Value);

The problem is that you aren't thinking about what is going on here: the value you are casting to a bool is not a bool value, so the cast fails: that can't be "fixed" at that point - you need to find out what it actually is and why it isn't the value you are expecting.
And the only way to do that is to use the debugger while your code is running and look at what the actual data looks like. No amount of code I could give you would fix that - because either the index is wrong, the data is wrong, the table isn't organised as you think it is, or it's totally the wrong table.
We can't tell you which of those: but the debugger probably can almost instantly!

As long as you keep mixing "business logic" in with your "data access" logic, your life will continue to be difficult.
You are simply copying and pasting each "case", without any thought to the amount of duplicate code you are creating.
I would tell you to rewrite what you've got instead of helping you to "fix" it (and continuing to support your bad habits).
Or are you getting paid by lines-of-code?
