Chrome error: Uncaught Syntax Error: Unexpected Token ILLEGAL

A html is working fine on IE, but can't work in Chrome and firefox.

Using console shows Chrome Uncaught Syntax Error: Unexpected Token ILLEGAL.

Solution: check whether the format of html is UTF-8 or not. Save as UTF-8 format should be fixed.

Using jsoncpp with VS2008

在專案使用jsoncpp build過程一些筆記:
1. Debug版沒什麼問題 直接用就好

2. Release版 首先要把Project properties->configuration properties->C/C++->code generation 改成/MT
但在我的project裡面用MT會有錯誤，我的project是使用Multi threaded DLL/MD
所以要把jsoncpp也改成MD(如下圖)。不知道是不是要跟project配合，沒實驗。













3. compile自己的專案會出現以下error
Error 857 fatal error C1083: Cannot open compiler generated file: '../../build/vs71/Release/lib_json\json_reader.asm': No such file or directory d:\jsoncpp-src-0.6.0-rc2\src\lib_json\json_reader.cpp 1
有兩個solution：
(1)將jsoncpp中build/vs71那個folder拉到跟error msg一樣的位置。這個case就是往上拉兩個folder層級。
(2)或到jsoncpp的project properties->configuration properties->C/C++->Output Files
將Assembler output改成No Listing就不會出現錯誤了。(如下圖)

簡單記一下VS2008使用lib的方法

1.先include header檔

Project properties->configuration properties->C/C++->General->Additional include directories

加入.\include所在目錄

2.Linker加入lib檔

Project properties->configuration properties->Linker->General->Additional Library dependencies

加入.\lib所在目錄

Project properties->configuration properties->Linker->Input->Additional dependencies 

加入.lib檔案名稱

也可以加入command line指令或用vs2008中tools->options->Projects and solutions->vc++ directories加入lib跟inlcude路徑。

None Border Dialog drag moving method

Set the dialog "Border" property to none , re-sizing or thin the dialog won't be able to be dragged moving

If you don't want the border of a dialog but also need the dragging feature, send WM_NCLBUTTONDOWN Message @ OnLButtonDown();


void CDlgExample::OnLButtonDown(UINT nFlags, CPoint point)
{
SendMessage(WM_NCLBUTTONDOWN,HTCAPTION,0);
CDialog::OnLButtonDown(nFlags, point);
}

LoadLibrary

@ DLL
extern "C" __declspec(dllexport) double SquareRoot(double d);

@ caller

typedef double (SQRTPROC) (double);
SQRTPROC* pFunc;
HMODULE hMod = ::LoadLibrary(_T("xxx.dll"));

if(hMod)
{
    pFunc = (SQRTPROC*)::GetProcAddress(hMod, " SquareRoot ");
    if(pFunc)
       double d = (*pFunc)(1.0);
}
