For those new to message boards please try to follow a few simple rules when posting your question.
Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
Newer versions of Visual Studio are installed without a makefile for the MFC library.
As I want to change some inner parts of MFC I need to compile the library.
...but without a makefile (or solution file) this is not possible.
Anybody out there which has got a working makefile for newer Visual Studios?
It is possible to get the name of logged in users from a service (you have already asked that and got an answer). Using that you can guess the the user directory path and verify it by checking if the pathe exists.
But a service should not modify user data and usually does not need to read user data.
You have not told us why you need access to user directories. Maybe there is a better solution for your problem.
Just a guess, since I never did it yet:
- enumerate currently logged i user using NetUserEnum or/and NetWkstaUserEnum functions to get the SID for every user;
- use these SIDs to get info for every user from registry (HKEY_USERS\<sid>\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders)
Hope, it helps (at least to move you in some potentially useful direction).
No, it is most definitely NOT undefined behavior. This is exactly the behavior one should expect. The variable a has the binary value of -26 decimal, or 0xFFFFFFE6 in 32-bit hexadecimal. When it is passed to printf with a %d format specifier it will be interpreted as a signed decimal value and -26 is printed. There is nothing undefined about that. It is interpreting the variable exactly as the format specifier is defined to. It may not be what you want but it is as expected.
Introduction to the data:
NOAA's National Centers for Environmental Information collects global climate data and aggregates this data to provide information on climate trends and variability. One product they offer is a monthly regional analysis. The following table gives "anomaly" data by continent for January 2017. "Anomaly" means the value is the temperature difference from the average temperature from years 1910–2000.
Continent Anomaly (C)
North America 3.18
South America 1.36
Your task is to develop an algorithm that would sort data such as these from least to greatest. Specifically, given an unsorted set of N decimal values, your algorithm should sort them to give an answer of the sorted data. For this set of N = 6, your algorithm should produce:
Execute your algorithm for a different set of data, such as a subset of the given data, data you make up, or another month's climate data, such as February 2017: https://www.ncdc.noaa.gov/sotc/global-regions/201702
Does your algorithm work for any N? Have you thought of corner cases it might need to handle, such as N = 0 or N = 1?
If the code actually runs it is only because of the way that the compiler lays down the stack and/or what the exact code did just before the first method was called.
In the method the pointer is considered to be non-initialized but because it is a pointer that was created on the stack it will have a value, whatever was in the memory that the stack is using at that point. Thus correctly stated 'garbage'.
