QUESTION
I have the following code for loading contents of the file and parse it with aeson into an object:
...ANSWER
Answered 2021-Oct-10 at 19:59Instead of forcing the result after closing the handle, you should force the result before closing the handle, here's how you can do that with BangPatterns:
QUESTION
I need a way to self-delete the executable within my Win32 C++ project, and I found a program that does it in C:
selfdel.c:
...ANSWER
Answered 2021-Aug-10 at 01:43FARPROC does not work the same way in C++ as it does in C. This is actually described in the CallWindowProc documentation:
...
TheFARPROCtype is declared as follows:
int (FAR WINAPI * FARPROC) ()In C, the
FARPROCdeclaration indicates a callback function that has an unspecified parameter list. In C++, however, the empty parameter list in the declaration indicates that a function has no parameters. This subtle distinction can break careless code.
...
So, you will have to use proper function-pointer signatures instead, eg:
QUESTION
My class has properties that need to be initialized. As I don't want to pass through a partially constructed object, and constructors can't/shouldn't be made async, I have been using the Factory Pattern described here, so my class looks like this:
...ANSWER
Answered 2020-Nov-23 at 13:44I think you should read Stephen Cleary's very next post stating that it's an oxymoron to have your asynchronously initialized object have an API that exposes a public non-asychronous property (AsyncProp1). This amounts to wanting an async property.
You could redesign the interface to this object so that any of its methods are also async and just let those methods internally ensure that it is initialized (awaiting InitAsync if necessary). ...if preventing misuse is your primary goal.
QUESTION
LRESULT WINAPI TextViewWndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
TextView* ptv = (TextView*)GetWindowLong(hwnd, 0);
switch (msg)
{
case WM_NCCREATE:
if ((ptv = new TextView(hwnd)) == nullptr)
return FALSE;
SetWindowLong(hwnd, 0, (LONG)ptv);
return TRUE;
}
ANSWER
Answered 2020-Aug-20 at 14:49Per the GetWindowLong() documentation:
nIndex
Type: int
The zero-based offset to the value to be retrieved. Valid values are in the range zero through the number of bytes of extra window memory, minus four; for example, if you specified 12 or more bytes of extra memory, a value of 8 would be an index to the third 32-bit integer.
...
The following values are also available when the hWnd parameter identifies a dialog box.
DWL_MSGRESULT
0
Retrieves the return value of a message processed in the dialog box procedure.
The code in question is for a window that wraps a TextView object. The window is NOT a dialog box, and there is an InitTextView() function beint called that registers a WNDCLASSEX whose cbWndExtra field is set to sizeof(TextView*) when calling RegisterClassEx():
QUESTION
I am trying to detect and prevent an object from containing itself in a form of recursion.
Example:
Product A contains a list of parts, some of which are of the type Product. When adding a Part to the list of parts that Product A contains, I want to verify it is not itself AND any of the product's parts don't eventually lead back to being Product A
ANSWER
Answered 2020-Jul-19 at 07:08for (Product product: products) {
if (this.equals(product)) {
return true;
}
return catch22(product);
}
QUESTION
I'm writing a function that handles the callback of a Stripe.com checkout session.
Basically, I receive some data in the body of the request, verify it with the Stripe node library, then I'm trying to write to Dynamodb to handle some backend business logic after the purchase is completed.
The problem is I need to keep this api endpoint open for Stripe to call it but also give the function authorization to write to dynamodb. When setting the authorizer: aws_iam, it requires the request to include an authentication token and when testing the webhook with Stripe it returns a "Missing Authentication Token" error.
When I remove the authorizer: aws_iam Stripe can call the webhook fine because the endpoint is open but then there's no permissions setup to allow writing to dynamodb. Seems like a catch22.
Here's my serverless:
...ANSWER
Answered 2020-Mar-06 at 21:25That's kinda strange. In your case you need to configure:
- API GW wide open (
authorizer: aws_iammeans restriction access to api gw endpoint only) - API GW must have permissions to invoke lambda function
- lambda function must have only access to DynamoDB
- remove CORS
Please - check lambda permissions (execution role) - check api gw (integration request role)
