我正在尝试用WinDbg调试一个C/C++ Win32动态链接库,但目前它由于访问冲突而无法加载。以下是日志中经过编辑的代码片段:
ModLoad: 77bd0000 77bd7000 C:\WINDOWS\system32\midimap.dll
ModLoad: ...\PyFM.fmx <-- THIS IS MY DLL
*** ERROR: Symbol file could not be found. Defaulted to export symbols for

我正在努力学习线程,以及C++和QT的基础知识。我有一个mainWindow按钮方法,它实际上将运行一个线程,并存储ui组合框文本的值:
void MainWindow::on_Request_Raw_Button_clicked(bool checked)
{
if(checked)
{
// Store the current request into var.
curr_request = ui->comboBox_2->currentText();
qDebug() << curr_request << &
当使用以下代码时,我得到错误"list iterator not dereferencable“:
bool done = false;
while (!_list_of_messages.empty() && !done) {
// request the next message to create a frame
// DEBUG ERROR WHEN NEXT LINE IS EXECUTED:
Counted_message_reader reader = *(_list_of_messages.begin());
if (re
我正在尝试将值排队到队列中,它工作得很好。当程序运行几个小时后,我得到以下错误
System.ArgumentException: length

我见过这样一个片段,用于使用条件注释在JavaScript中检测IE。
var ie = (function(){
var undef, v = 3, div = document.createElement('div');
// the while loop is used without an associated block: {}
// so, only the condition within the () is executed.
// semicolons arent allowed within the condition,
我正在开发一个具有多个并行写操作的OLTP环境。我在关于自动增量锁定的文档中找到了这,但是我仍然感兴趣地想知道更多关于它的细节。有谁能告诉我mysql在下面的情况下是如何通过自动锁定来处理auto_increment列的吗?
1.When there are multiple mysql users performing inserts in parallel ?
2.When a user updating maximum value of the auto increment column and the same time another user is inserting a new
