The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

GetOpenFileName & OPENFILENAME lpstrFilter runtime string problem

Asked by cafechris in C++ Programming Language

Tags: lpstrfilter, getopenfilename, openfilename

I get a char *  to my function argument. It is a string that I parse to create a few strings from.
Example:
"var1,var2,1234,Text (.txt)|*.txt|Bitmap (.bmp)|*.bmp||"

I have a function that parses the strings so I end up with one :
"Text (.txt)|*.txt|Bitmap (.bmp)|*.bmp||"

So I replace the '|' with '\0' :
"Text (.txt)\0*.txt\0Bitmap (.bmp)\0*.bmp\0\0"

char filter[512];
strcpy(filter,"Text (.txt)\0*.txt\0Bitmap (.bmp)\0*.bmp\0\0 ") ;

Now it should be in the format to set my lpstrFilter:
OPENFILENAME  opfn;
opfn.lpstrFilter = filter;

and try to pass it as lpstrFilter to GetOpenFileName(&opfn)

The problem is that the filter doesn't work properly. I get The First part working perfectly.
- Text (.txt)
but the other options in the filter comboBox  are crazy unrecognizable characters. (2 lines of them)

How can I get this to work?


// here is the function that changes '|' to '\0'
// for(i=0;i<strlen(filters);i++)
// {
      // if(filters[i] == '|')
      // {
            // filters[i] =  '\0';
      // }
// }
