2.pvs_studio_V595

msg="The ‘browser‘ pointer was utilized before it was verified against nullptr. Check lines: 280, 283."

3.pvs_studio_V721

msg="The VARIANT_BOOL type is utilized incorrectly. The true value (VARIANT_TRUE) is defined as -1. Check: ((& isPreview)->boolVal) = m_isPreview."

4.pvs_studio_V811

msg="Decreased performance. Excessive type casting: string -> char * -> string. Consider inspecting first argument of the function fileExists."

5.pvs_studio_V547

msg="Expression ‘j >= 0‘ is always true. Unsigned type value is always >= 0."

6.pvs_studio_V716

msg="Suspicious type conversion in assign expression: ‘BOOL = HRESULT‘."

7.pvs_studio_V745

msg="A ‘wchar_t *‘ type string is incorrectly converted to ‘BSTR‘ type string. Consider using ‘SysAllocString‘ function."

8.pvs_studio_V746

msg="Type slicing. An exception should be caught by reference rather than by value."

9.pvs_studio_V724

msg="Converting type ‘int‘ to type ‘VARIANT_BOOL‘ can lead to a loss of high-order bits. Non-zero value can become ‘FALSE‘."

10.pvs_studio_V814

msg="Decreased performance. Calls to the ‘wcslen‘ function have being made multiple times when a condition for the loop‘s continuation was calculated."

11.pvs_studio_V575

msg="The null pointer is passed into ‘memcpy‘ function. Inspect the second argument."

12.pvs_studio_V501

msg="There are identical sub-expressions to the left and to the right of the ‘!=‘ operator: m_fitMode != m_fitMode"

13.pvs_studio_V512

16.pvs_studio_V570

msg="The ‘height‘ variable is assigned to itself."

17.pvs_studio_V576

msg="Incorrect format. Consider checking the third actual argument of the ‘wsprintfW‘ function. To print the value of pointer the ‘%p‘ should be used."

18.pvs_studio_V704

msg=‘this == nullptr‘ expression should be avoided - this expression is always false on newer compilers, because ‘this‘ pointer can never be NULL.

19.pvs_studio_V763

msg="Parameter ‘handle‘ is always rewritten in function body before being used."

20.pvs_studio_V510

msg="The ‘Format‘ function is not expected to receive class-type variable as second actual argument."

24.pvs_studio_V672

msg="There is probably no need in creating the new ‘context‘ variable here. One of the function‘s arguments possesses the same name and this argument is a reference.

25.pvs_studio_V517

msg="The use of ‘if (A) {...} else if (A) {...}‘ pattern was detected. There is a probability of logical error presence. Check lines: 47, 59."

26.pvs_studio_V561

msg="Recurring check. The ‘if (!layout)‘ condition was already verified in line 1032

28.pvs_studio_V611

29.pvs_studio_V674

msg="The literal ‘10.5‘ of ‘double‘ type is being implicitly cast to ‘int‘ type while calling the ‘setPointSize‘ function. Inspect the first argument."

30.pvs_studio_V541

msg="It is dangerous to print the string ‘strParam‘ into itself."

31.pvs_studio_V542

msg="Consider inspecting an odd type cast: ‘unsigned short‘ to ‘wchar_t *‘."

37.pvs_studio_V590

msg="Consider inspecting the ‘lResult == 0L && lResult != 234L‘ expression. The expression is excessive or contains a misprint."

38.pvs_studio_V617

msg="Consider inspecting the condition. The ‘SizeY_FitContent‘ argument of the ‘|‘ bitwise operation contains a non-zero value."

39.pvs_studio_V712

msg="Be advised that compiler may delete this cycle or make it infinity. Use volatile variable(s) or synchronization primitives to avoid this."

40.pvs_studio_V502
