Hello.
I have a project in VS2017 in which i use SFML. It is a database for students.
I have encountered an error as I was trying to implement a dialog box for opening files. As soon as the dialog box is closed (with no error message) the program displays errors in opening the fonts and the images that previously worked.
The code I am using for displaying the dialog box is as follows:
string testing()
{
OPENFILENAME ofn; // common dialog box structure
char szFile[260]; // buffer for file name
HWND hwnd = NULL; // owner window
HANDLE hf; // file handle
// Initialize OPENFILENAME
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = hwnd;
ofn.lpstrFile = szFile;
// Set lpstrFile[0] to '\0' so that GetOpenFileName does not
// use the contents of szFile to initialize itself.
ofn.lpstrFile[0] = '\0';
ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrInitialDir = NULL;
ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;
// Display the Open dialog box.
if (GetOpenFileName(&ofn) == TRUE)
{
hf = CreateFile(ofn.lpstrFile,
GENERIC_READ,
0,
(LPSECURITY_ATTRIBUTES)NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
(HANDLE)NULL);
return ofn.lpstrFile;
}
return "";
}
And the function is called like this:
string s;
s = testing();
cout << s << '\n';
The error messages I get are:
Failed to load image "images/flag.png". Reason: Unable to open file
Failed to load image "images/logo_nb.png". Reason: Unable to open file
Failed to load image "images/student_data.png". Reason: Unable to open file
Failed to load font "fonts/Times_New_Roman_Normal.ttf" (failed to create the font face)
