Remove a character from a long string

I have the following string:

https://example.com/get/ea34b8062cr2533eed0b4302e44d4090e26ae3c01bb1124292f3c970_1280.jpg

I want just remove the character s from this part https and return the whole string again but without s character.

wxString imgURL = "https://example.com/get/ea34b8062cr2533eed0b4302e44d4090e26ae3c01bb1124292f3c970_1280.jpg";
imgURL.Remove(imgURL.find('s'));
this->m_textShowData->SetValue(imgURL);

Unfortunately, the previous code removes the s character but doesn't return the whole string again but it returns http only.

How to remove the character s and then return the whole string without that character?

Just use the erase function:

 imgURL.erase(4,1);

According to the documentation Remove() function has overload where you can specify the number of characters you want to remove from given position.
So this should do the trick:

imgURL.Remove(imgURL.find('s'), 1);

But this function is preserved only for compatibility reasons and as the documentaion mentions, it should not be used in new code. Take a look at erase() function instead, which has the same syntax as Remove()
