C - 关于Windows奇怪的行为 [英] C - on Windows Odd behavior
问题描述
我的C程序出现了一个奇怪的错误。它从VB包装程序创建的文本文件中接收参数。其中一个输入是作业名称。当为此作业名输入某些值时，代码会发生爆炸，而其他值则不会。此作业名用于创建目录。
当作业名具有LLLLLLL _ ### LL时，它会崩溃，其中L =字母，＃=数字，_ =下划线。但是，如果只有2位数字& 3个数字后面有2个字母或1个字母，它可以正常工作。不幸的是，用户通常使用这种格式命名作业名称（例如：Bottle_400ml）。
有没有人见过这样的东西？
谢谢，
Sitko。
Hi,
I''m getting a weird error with my C program. It receives parameters from a text file that is created by a VB wrapper program. One of the inputs is a "jobname". The code bombs when certain values are inputed for this jobname, but not others. This jobname is used to create a directory.
It crashes when the jobname has LLLLLLL_###LL, where L = letters, and # = digits, and _ = underscore. But, if there are only 2 digits & 2 letters or 1 letter after the 3 digits it works fine. Unfortunately, the user typically names the job name with this format (ex: "Bottle_400ml").
Has anyone seen anything like this before?
Thanks,
Sitko.
推荐答案
发布读取作业名的代码。
奇怪的错误有点模糊。究竟是什么样的错误??
Post the code that reads the jobname.
"weird error" is a little vague. Exactly what kind of error??
弹出的错误是：
" D：\ Bottle_400mL
'' - ^''不被识别为内部或外部命令，
可操作程序或批处理文件。
文件名，目录名或卷标语法不正确。
（注意：^符号是一个向上箭头字符。）
起初而不是 - ^它说/拒绝不被认为是内部......
我认为导致错误的代码是：
The error that pops up is:
"D:\Bottle_400mL
''-^'' is not recognized as an internal or external command,
operable program or batch file.
The filename, directory name or volume label syntax is incorrect."
(note: the "^" symbol is an "up arrow" character.)
At first instead of "-^" it said "/Decline" is not recognized as an internal...
The code that I ''think'' cause the error was this:
if（strcmp（strType，" Decline"）== 0）
{
strcpy（sysCall，" mkdir"）;
strcat（sysCall，gstrJobname）;
system（sysCall）;
}
if（strcmp（strType，" Decline"）== 0）
{
strcpy（sysCall，" mkdir"）;
strcat（sysCall，gstrJobname）;
strcat（sysCall，斜杠）;
strcat（sysCall，strType）;
system（sysCall）;
}
if (strcmp(strType,"Decline")==0)
{
strcpy(sysCall,"mkdir ");
strcat(sysCall,gstrJobname);
system(sysCall);
}
if (strcmp(strType,"Decline")==0)
{
strcpy(sysCall, "mkdir ");
strcat(sysCall, gstrJobname);
strcat(sysCall, slash);
strcat(sysCall, strType);
system(sysCall);
}
再次告诉我这段代码是如何工作的。看起来strcmp在每种情况下都是正确的 - 并且yioiu有不同的内容。
另外，在Windows端，你的斜线必须是\\。
Tell me again how this code works. It looks like the strcmp is true in each case-and yioiu haver different contents.
Also, on the Windows side, your slash has to be \\.
