    disabling minimize and mazimize boxes on Microsoft display output

    I would like to disable the minimize and maximize boxes on the Microsoft console output, because if you use them running a C console application they cause bugs. It can easily be done running C++ or C#, but there is no information for C on the Internet. You cannot transpose what is shown for C++ and C# because of no information as to the library to be used in C with the code that is shown for C++ and C#.

    So fix the bugs, rather than trying to cover up the evidence and making life hard for your users.

    If they want to press the X in the corner, they should be able to.

    Which is odd really, because the Win32 API is fundamentally a 'C' API to begin with.

    Don't let the "C++ example" fool you.
    Unless there are specific C++-isms in the example like templates, classes, chances are, it will compile just fine in C (or will be easy to make compile in C).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I didn't say I want to get rid of the x at the top of the output. I want to disable the maximize and minimize buttons of the output frame.

    Maybe:
    Code:
    void disableMinimizeAndMaximizeButtons(HWND hwnd)
    {
        SetWindowLong(hwnd, GWL_STYLE,
            GetWindowLong(hwnd, GWL_STYLE) & ~(WS_MAXIMIZEBOX|WS_MINIMIZEBOX));
    }
    If you want the truth to stand clear before you, never be for or against. - Sent-ts'an

    Thank you very much for the code. But I regret to say, it doesn't work. I copy/pasted your code to my application, so there cannot have been any copying errors.

    Unless you define "doesn't work" there's nothing else I can do.

    I love the "I copied and pasted it so I can't possibly be at fault" reasoning!
    I assume you found whatever mistake you made.

    So, did you call the function or do you think it will work because programming is magic?

    If this is your contribution, I am not sure I understand. I tried getting the code to work by making a few changes, however to no avail.

    How, specifically, doesn't it work? Simply saying it doesn't work provides no information at all. Many of us probably don't even use Windows so you need to provide specific details regarding how it doesn't work. Did you call the function disableMinimizeAndMaximizeButtons from within your program?

    Do you know what a function is?
    Do you know how to call a function?
    Did you call the disableMinimizeAndMaximizeButtons function?

    I don't think I made a mistake trying to implement the function. When the code did not work I tried some changes . Moving the declarations from the parameter list to the body of the function. Changing the function for it to be similar to a function in Basic that I know of, and which does work. Both didn't solve the problem. I was hoping to hear more from you. So to answer your question: no, I did not find any mistake.

    I was hoping you'd answer the question. Nobody asked if there was a mistake in the function. The question was, did you call the function?

    Edit: After you answer the question that was asked can you please post your test code (I imagine/hope that it's simply a few includes, the function above, and a small main() with 1 or two lines of code)

    Maybe you did. Since you didn't show your code, it is reasonable to suppose that you made a mistake. Show your code.

    That makes it sound like you didn't actually call the function: surely you cannot just turn the parameter into a local variable because you would need to pass the handle of the current window to the function?

    You're being terribly vague. What did you change the C function to? What is the Basic function code?

    So to answer your question: no, I did not find any mistake.
    The question isn't "did you find any mistake?" The question is: "how does it not work"? For example, did you encounter a compile error, and if so, what was the error message? Did you call the function and then find that there was no intended effect, and if so, what is the relevant code?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    I don't have Windows but looking at the docs the function should, in principle at least, work. How are you getting the value for hwnd?
    We really need to see your test code
