    Re: Memory Leak in Constructor?

    I misunderstood how it works. The program does have some problems. I started down the memory leak possibility when I started getting corruption in the heap errors on program exit.

    Re: Memory Leak in Constructor?

    I put a breakpoint at the beginning of the constructor for the app class. Then I put _CrtDumpMemoryLeaks(); on the first line of the constructor. Stepping past the call to the dump memory leaks...

    Memory Leak in Constructor?

    I know memory leak checking can sometimes have false positives. I'm wondering if this is one of them, or if I'm doing something wrong.

    I turned on memory leak checking by adding

    Re: Reading ASCII Strings into a Unicode Program

    I fixed it after you pointed it out to me.

    I'm copying the contents of the pointer right after it's set and then discarding the pointer, so while it was less than optimal coding practice, it...

    Re: Reading ASCII Strings into a Unicode Program

    The class I'm using to read the ini is called CSimpleIni from here http://code.jellycan.com/simpleini/. Using this, I can eliminate the ANSI function calls in the program.

    It's usage is pretty...

    Re: Reading ASCII Strings into a Unicode Program

    It returns a wchar_t* which as far as I can tell is identical to a TCHAR * in Unicode, but the compiler couldn't deal with it without the cast.

    Re: Reading ASCII Strings into a Unicode Program

    Unless someone can point me to some literature that says otherwise, I'm pretty well convinced this is an MFC architecture issue. I put the exact same code in the mainframe and the app class. They...

    Re: Reading ASCII Strings into a Unicode Program

    Thanks for the info. I learned C pretty much formally, but taught myself C++ on the job. There are some gaps in my education.

    One thing, I wasn't talking about making a copy of IniPath, just a...

    Re: Reading ASCII Strings into a Unicode Program

    Moving the loading code to the app class works.

    I am still wondering why it wouldn't work right in the main frame.

    I tried moving the code to the document, and it loads OK. There is something weird with loading it in the main frame. I found I could get the strings to load if I created a TCHAR string at the top...

    Re: Reading ASCII Strings into a Unicode Program

    m_CfgData is a struct with several strings and some ints. I've tried defining it a few different ways.

    I removed the memset for now. Removing the & from in front of the m_CfgData won't compile. ...

    Reading ASCII Strings into a Unicode Program

    I am developing a new app in MFC under VC 2005. Part of the program has to deal with text from files that are used by some old ASCII programs (the programs were created before unicode existed).

  18. [RESOLVED] Is There a Way to Set the Short Filename Programatically?

    I see you can use

    fsutil file setshortname

    to force the short name of a file to something specific, but is there a way to do this programatically with the API?

    If there is, it will save me...

    Re: Why is winapi so messy?

    Probably my biggest gripe with Windows. And they didn't do all that great a job at fool proofing Windows for the low end user either. For that, Mac OS did a better job.

    The problem is a bit more difficult because the beginning and end point of the two curves may not be the same X, though this may be OK. Additionally one curve can have more points than the other. ...
