PostMessage（）错误 [英] PostMessage() error
问题描述
PostMessage（）函数在
循环中运行700次后返回ERROR_NOT_ENOUGH_QUOTA，但磁盘空间和内存仍然足够大。
有什么建议可以解决这个问题吗？
谢谢。

这听起来像是一个安全限制，以防止过多的
消息。在正常情况下，它似乎表明
你试图将消息发布到一个不处理
消息的窗口。
>任何解决此问题的建议？
不要这样做。
允许其他应用程序运行并处理其消息。

谢谢。
为什么要尝试此测量？你想做什么？
Windows GUI消息的目标是GUI /窗口交互。通常，
达到这些限制意味着你正在颠覆GUI消息传递系统
来做别的事情，这不是为它设计的。
例如，我已经看过使用PostMessage的采集循环等。不要
这样做！

消息的窗口。
这里是示例代码。我删除了createprocess（）函数。

int main（）
{
....
while （fgets（psBuffer，BUFFER_SIZE，stdin）！= NULL）{
PostString（hwndText，psBuffer）;
}
.... }
void
PostString（HWND hwnd，char * pc）
{
while（* pc）{
PostMessage（hwnd，WM_CHAR，（unsigned char）* pc，1L）;
pc ++;
}
}
在处理了4k stdin管道数据之后，得到了ERROR_NOT_ENOUGH_QUOTA用于函数的问题
PostMessage（）我有14K的
stdin数据处理）
你认为14k的stdio管道数据对于PostMessage（）太大了吗？
谢谢。
PostMessage() function returns ERROR_NOT_ENOUGH_QUOTA after running in a
loop for 700 times, but the disk space and memory are still big enough.
any suggestion to resolve this problem?
thanks.

messages. In normal circumstances it would seem to indicate that
you''re trying to post messages to a window that''s not processing
messages.
>any suggestion to resolve this problem?Don''t do it.
Allow the other application to run and process its messages.

thanks.Why are you trying this measurement? What are you trying to do?
Windows GUI messages are aimed at GUI/window interacting. Usually,
hitting those limits means you are subverting the GUI messaging system
to do something else, something it wasn''t designed for.
Eg, I have seen acquistion loops or the like using PostMessage. Don''t
do it!

here is the sample code. I removed createprocess() function.
>int main()
{
....
while (fgets(psBuffer, BUFFER_SIZE, stdin) != NULL) {
PostString(hwndText, psBuffer);
}
....}
void
PostString(HWND hwnd, char *pc)
{
while(*pc) {
PostMessage(hwnd, WM_CHAR, (unsigned char) *pc, 1L);
pc++;
}
}
it get the problem of ERROR_NOT_ENOUGH_QUOTA for the function of
PostMessage() after processing 4k of stdin piped data ( I have 14K of
stdin data to process)
do you think 14k of stdio piped data is too big for PostMessage()?
thanks.
