本文介绍了我的程序出现问题，调试断言失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的代码正常，问题是当我单击图片(第一行的前三张图片)时，它说调试断言失败".令人困惑的.....
My code is ok, the problem is that it said "Debug assertion failed" when I clicked the pictures (the first three pictures of the first row ). confusing .....

推荐答案
没有人会深入研究您的代码以找到如此大量的代码中的问题.尝试仅发布相关代码.
此外，当发生类似情况时，您的第一个反应应该是使用调试器来缩小问题的范围.与在论坛上提问相比，您得到的结果要快得多.
Nobody is going to dig into your code to find the problem in such amount of code. Try posting only relevant code.
Furthermore, when something like that happens, your first reflex should be to use your debugger to narrow down the problem. You''ll get much faster results than asking a question on a forum.
{ if(cf.Read(&BFH，sizeof(BITMAPFILEHEADER))！= sizeof(BITMAPFILEHEADER)||
BFH.bfType！=''MB''||
cf.Read(pDib，dwDibSize)！= dwDibSize)
{
删除[] pDib;
pDib = NULL;
返回FALSE;
}
}
在try中的BFH.bfType！=''MB''应该改为BFH.bfType！=''BM''
{ if(cf.Read(&BFH, sizeof(BITMAPFILEHEADER))!=sizeof(BITMAPFILEHEADER)||
BFH.bfType!=''MB''||
cf.Read(pDib, dwDibSize)!=dwDibSize)
{
delete [] pDib;
pDib = NULL;
return FALSE;
}
}
在 try 中的 BFH.bfType!=''MB'' 应该 改为 BFH.bfType!=''BM''
cgpsview1.LoadBmp((LPTSTR)(LPCTSTR)szFileName00) ;
您可以更改:
例如
cgpsview1.LoadBmp(szFileName00.c_str());
cgpsview1.LoadBmp((LPTSTR)(LPCTSTR)szFileName00);
u can change :
eg
cgpsview1.LoadBmp(szFileName00.c_str());
