This error usually happens if you don't provide the correct structure size when using one of our functions. The normal procedure when using any structure is:
1. After declaring the structure, initialize it to zeros.
2. If it has a size member (usually named uStructSize), assign the structure size to that member. In C and C++, this is done like this:
myStruct.uStructSize = sizeof(myStruct);
3. If a function has a struct size parameter, also pass the structure size, like this:
FunctionName(&myStruct, sizeof(myStruct), ...);

If that doesn't solve it, can you send me a small working project that reproduces the problem.
Notes:
1) When you send any attachments, put them in a ZIP or RAR file to ensure our server delivers them correctly.
2) If you are uploading it to our support forum, then don't click on preview, as you will lose the attachment.
3) Please do not send your full application.
4) You can either post here or email the project to support@leadtools.com

Dear Mohammad,
Thank you for your support, but when I pass arabic letters the QR-Image doesn't read it, if there is a function in LEADTOOLS or any solution for this, can you give it to me, please.

AbdlHakim,

You already opened an email ticket about this issue. Please use either the forums or email, but not both for the same issue.

 

My colleague Mohammad will follow up your Arabic QR-code problem in ticket# 2012022910000277.
