❔ Some bug i guess

Code that works

Task.Run(() => Static_class_name.START(param1, param2, param3));

Task.Run(() => Static_class_name.START(param1, param2, param3));

*inside the static class Static_class_name *

public static Task START(decimal param1, decimal param2, int param3)
{}

public static Task START(decimal param1, decimal param2, int param3)
{}

But i want to send more paramters like extra 3 string params which makes the function not want to run Code that does not work

Task.Run(() => Keyboard_and_Mouse.START(param1, param2, param3, param4, param5, param6));

Task.Run(() => Keyboard_and_Mouse.START(param1, param2, param3, param4, param5, param6));

*inside the static class Static_class_name *

public static Task START(decimal param1, decimal param2, int param3, string param4, string param5, string param6)
{}

public static Task START(decimal param1, decimal param2, int param3, string param4, string param5, string param6)
{}

A small modification in the code for Task.Run() that does not work

var t1 = param4;
var t2 = param5;
var t3 = param6;
Task.Run(() => Keyboard_and_Mouse.START(param1, param2, param3, t1, t2, t3));

var t1 = param4;
var t2 = param5;
var t3 = param6;
Task.Run(() => Keyboard_and_Mouse.START(param1, param2, param3, t1, t2, t3));

Now this will work and then function would run anyone got any suggestions? I will be open to live stream if needed for a better understanding. It does not make sense that when i put the values param4, 5, 6 directly to the function call, it does not run but when i put it in another variable and then put the variable in the function parameters, it works. (NOTE : all the parameters are coming from windows form application) param1 -> itemA_numericupdown.value param2 -> itemB_numericupdown.value param3 -> itemB_numericupdown.DecimalPlaces param4 -> itemC_combobox.Text param5 -> itemD_combobox.Text param6 -> itemE_combobox.Text

im not too keen on winforms, but it might have something to do with that you are trying to access a UIelement from another thread when you are creating a new variable it will copy the string still in the uithread. and since you are now working without a uielements it works but thats just my 2 cents

infernus8349OP•2y ago

but param1,2,3 are also from windows forms i am not sure why this is happening but i am going to try to put the parameters 4,5,6 as .ToString() so that it will actually copy let me see how that goes nope, it does not work

ACiDCA7•2y ago

just to make sure, you meant

Task.Run(() => Keyboard_and_Mouse.START(itemA_numericupdown.value, itemB_numericupdown, itemB_numericupdown.DecimalPlaces, itemC_combobox.Text, itemD_combobox.Text, itemE_combobox.Text));

Task.Run(() => Keyboard_and_Mouse.START(itemA_numericupdown.value, itemB_numericupdown, itemB_numericupdown.DecimalPlaces, itemC_combobox.Text, itemD_combobox.Text, itemE_combobox.Text));

this doesnt work but

Task.Run(() => Keyboard_and_Mouse.START(param1, param2, param3, t1, t2, t3));

Task.Run(() => Keyboard_and_Mouse.START(param1, param2, param3, t1, t2, t3));

wherever param1/2/3 are coming from, does

infernus8349OP•2y ago

yea yeah in the question i named param1, param2 was becuase it would be more cleaner in acutal code, its not exactly param1, 2, 3 those are actaul values direclty from windows form only the last 3 are making the problem

ACiDCA7•2y ago

hmm ok

infernus8349OP•2y ago

so i put them in variables t1,2,3 and then sent those 3 variables during function call that works i still dont know exactly why it does not work if sent directly to function call than putting it in a variable i am hoping someone can help me in this

ACiDCA7•2y ago

btw what exactly do you meant by "Code that does not work" do you get a runtimeexception?

infernus8349OP•2y ago

no, after the Task.Run() executes, the function i mentioned inside Task.Run() just does not run no error, just does not run now that you have mentioned, let me try putting it in try catch statement hold on

ACiDCA7•2y ago

can you put a await in fronbt of Keyboard_and_Mouse

infernus8349OP•2y ago

like Task.Run( () => await Keyboar

ACiDCA7•2y ago

basicly

Task.Run(() => await Keyboard_and_Mouse.START(param1, param2, param3, t1, t2, t3));

Task.Run(() => await Keyboard_and_Mouse.START(param1, param2, param3, t1, t2, t3));

infernus8349OP•2y ago

like this? ok hold on cannot use it as the fucntion that uses Task.Run() is not async Start_function() contains the Task.Run() and its not async also this Start_function() is being run by a function which run during the buttonclick of windows form i just tried putting the Task.Run() in try catch, it never got caught some hidden problem is happening which makes the function not want to run if last 3 parameters are sent directly than putting it in some variables and passing it over

ACiDCA7•2y ago

yea there are some shenanigans regarding not awaited tasks

infernus8349OP•2y ago

wish it alreayd showed me some error let me try to send 4 parameters, i never tried that, hold on

ACiDCA7•2y ago

there is a explanation for it but i currently dont have the mental capacity to explain it in detail..xD

infernus8349OP•2y ago

doesn't work xD i think this got something to do with where the data is coming from i think its something related to combobox.Text

ACiDCA7•2y ago

anyway. did you try to not make it a anonymous method and then create a breakpoint in it

infernus8349OP•2y ago

nope, let me try OK, IT WORKS!!!!!!!!!!! looks like Task.Run() is on drugs
