HI im using a HP 250 G7 Notebook PC and suddenly my network adapter the realtek rtl8822ce 802.11ac pcie adapter. Seems to have just disappeared some times it comes back but not for ever its been 2 days with no internet and ive tried everything wlan command promt all that i even reseted my computer and system restrord pls help and i cant use ethernet.

Memory profiling an app designer app?
My app designer app has a memory leak. I don’t understand how this would happen, because I have only a finite number of array variables, and I assume that when the data in one of these is replaced, the old data are flushed and garbage collected. Right?
But anyway, I need to do memory profiling and see when the upticks in usage are happening. The documentation I can find mostly refers to profiling for speed, and profiling small chunks of code. How do I profile for memory, and watch the whole app? (Or sprinkle memory usage checkpoints throughout my code?) And an old third-party post I see a reference to a built in command memory, but it seems to no longer exist, it gets an error "Function MEMORY is not available on this platform." (I’m using a Mac.)

Intune – Remote Help – Licensing and Unattended Control
Greetings,
First: Like others on the interweb I am struggling to find the value of this solution when it is necessary to license both the helper and sharer. ScreenConnect and/or other secure solutions offer more control and value – IMO. Microsoft – please reconsider the addin license structure and cost.
Second Question: The Remote Help claims to offer unattended control. My expectation of this would be – the helper connects to the endpoint when there’s no one (as sharer) logged in to approve the connection. Is this possible or not?
Thank you,

Is it possible to customize the Task cost calculation?
I have a question on how to customize the calculation of Task costs.
A bit of context: in my research organization, most of our research projects are funded by institutions (European Commission, regional agencies, …), which funding rates differ between each other. Example: the EC reimburses all direct costs (i.e. personnel + equipment + travel) and adds 25% of indirect costs rate; a regional agency reimburses only 10% of indirect costs and they only apply to the personnel costs.
I have created a Project custom field for the funding scheme (EC, …) and some custom fields for our resources (Manpower, Equipment, Travel, …). My objective is to create a custom Cost1 field which would test the type of funding scheme and the cost category, and apply the corresponding formula.
The problem is that I don’t see how to access the resource individual costs under the Task Usage view, it seems the formulas only apply to the total cost of the Task.
Does anyone have a clue of how I could achieve what I need? I hope the explanations above were clear enough.
Thanks in advance!
Christophe.

end Created a Newton System Solver for Non-linear system, but when I try to run it for this function, I get that error for line 21 in the Slammer1 function. The Solver does work with other generic functions, and when I just input my initial guess (y0 = [5e4,0,0,0,5e4]) in Slammer1, it work as well. But when I try to join them together it falls apart. I’ve checked over and over again, I really have no idea what else to do. Thanks in advance.

Configuring a subsystem as an AUTOSAR SW-Component is not supported. Please convert the subsystem to a model and then configure the model as an AUTOSAR SW-Component.
Hello,
I am trying to generate a C code which is compliant with autosar from a model (I am using Matlab 2020 for code generation) but when I generated the code I get this error:
Error using Simulink.ModelReference.Conversion.SubsystemConversion/convert
Configuring a subsystem as an AUTOSAR SW-Component is not supported. Please convert the subsystem to a model and then configure the model as an AUTOSAR SW-Component.
So to convert the subsystem to model I select Subsystem Block I want to convert then in Subsystem Block tab, select Convert > Model Block
For conversion, some checks need to be passed but my check is failed in ^ Check subsystem content and I get this error

Arduino simulink gets wrong timing with pulse generator
Hi, I’m facing a problem with the arduino package for simulink. I set up the model to fixed step discrete with a step size of 0.001 s. In the model I’m trying to do 2 things: blink an led each second(for 1 s the led is on and for 1 s is off); Print to the serial a number coming from a constant block of simulink. I tried setting the pulse generator pulse type time based, specifying the 2 seconds period with 50% pulse width, and also sample based, specifiyng the sample time of 0.001s (as the model) and imposing period of 2000 samples and pulse width of 1000 samples, to get the correct timing. Both ways i cannot get the led to blink with the correct timing, it seems like it is taking much longer, while i can see that the arduino is continuously printing the number on the serial, through the serial monitor of arduino ide after i deployed the code. Interestingly, if i delete the serial print block, the led blinks correctly, with both pulse types (time based and sample based). What am i not getting right? Thanks

Permanently delete users
Hello
Please i need your help on this issue.
I would know to know how to permanently delete users from their list without waiting for the usual 30-day period.
I would like all of my deleted users to be removed immediately from the list, rather than waiting 30 days.
