could not Load the dll

recently,i run into a very annoy bug when i run code below

hdl=loadlibrary("dirlog-c.dll"),the fllowing function getlasterror() return 126,that is explained in msdn

ERROR_MOD_NOT_FOUND
　　126 (0x7E)
　　The specified module could not be found.

the specified moudle could not be found,but,i surly confirm that i have set the correct path.i found a tool named depend.exe on website,which include in VS by default,you can just <a href=https://www.dependencywalker.com>download</a> if you can not find it,it is very simpy and tiny tool.

click the depend.exe and run it.

open the dirlog-cl.dll.or you can just drag it into the depend.exe ,it will be take a few time that the software to analyse the dll

we can see there is somthing wrong with the pcre.dll on which my dirlog-cl.dll depends. i miss it ,the pcre.dllcan not found

so, i download the pcre.dll and put it under the debug folder. and use the depend.exe to check the dirlog-cl.dll again,it shows as below

it make sense!! i load the dirlog-cl.dll,but it miss the pcre.dll,that is why the specified module could not be found.

NOTE:there are many reason when you get the 126code return,like the wrong path,or you actually use the loadlibrayW() not loadlibrayA(),they are difference when you pass the parameter,and so on
