Call HHA_COMPILEHHP compile CHM project

There are two methods of compiling a CHM project (. hhp):

Call Hhc.exe

Call HHA_COMPILEHHP

Call Hhc.exe compile with the following code:

// strChmFileName为你的hhp文件的长文件名
CString strCmdLine;
strCmdLine = "hhc.exe ";
strCmdLine += strChmFileName;
WinExec(strCmdLine, SW_SHOWNORMAL);

There are many drawbacks to invoking this method, first, there is no compilation progress, no prompts, and according to my tests, there is no support for the file names with spaces. The general professional CHM production software is called the Hha.dll in the HHA_COMPILEHHP function to compile. We do not discuss how to generate a CHM engineering file here, which can refer to the files generated by the HTML Help Workshop. Call HHA_COMPILEHHP, Microsoft did not provide function declarations, nor did it provide help information. (it is said to sign the agreement with Microsoft, before you can get the function declaration and related headers) reference to an online introduction using Delphi to implement function calls, plus my little experiment, finally I VC realized. OK, let's see how I do it.

First of all, HHA_COMPILEHHP parameters:

(const char*, LPVOID, LPVOID, int)

The first parameter is the HHP file name you want to compile

The second parameter is the compile log callback function

The third parameter is the compile progress callback function

The fourth parameter doesn't know what to use, I put him to 0

Start writing code.

void Ccompilechmdemodlg::buildchmfile (CString strhhpfile)
{
HINSTANCE hInstLib;
typedef BOOL (WINAPI *myfunc) (const char*, LPVOID, LPVOID, int);
BOOL Ffreeresult, fruntimelinksuccess = FALSE;

Get a handle to the DLL module.
hInstLib = LoadLibrary ("Hha.dll");

If The handle is valid, try to get the function address.
if (hInstLib!= NULL)
{
Procadd = (MYFUNC) GetProcAddress (hInstLib, "hha_compilehhp");

If The function is valid, call the function.
LPCSTR Pzfilenmae = Strhhpfile.getbuffer (Strhhpfile.getlength ());
if (fruntimelinksuccess = (procadd!= NULL))
{
if (Procadd (Pzfilenmae, Funlog, Funproc, 0))
{
}
}

Free the DLL module.
Ffreeresult = FreeLibrary (hInstLib);
}

if (M_pstatusbar)
M_pstatusbar->setpanetext (0, "compile complete!") ");
If Unable to call the DLL function, use a alternative.
if (! fruntimelinksuccess)
printf ("message via alternative method\n");
