Often seen people asking for help will solve it himself. So am I.
I am not expert, will make a lot of stupid mistakes ,but this seems work. Please add what you think that should be the right thing to do.
1. Open the DCEF_2010.dproj,
2. copy DLL from bin\win32 directory to package directory.( I have done once
without copying DLL, demo program guiclient can compile but will have error
126 when executed.)
3. build the project. I find it produce the .bpl into
c:\users\public\documents\RAD Studio \7.0\bpl
I cannot find the reason.
2. move the bpl back to package directory for neatness.
3. install component on that bpl file.
4. I have copied a lot into demo\guiclient directory to compile and successfully run.
( it seems that DLL being statically linked during bpl creation, as having DLL
in demo\guiclient run with error 126, after rebuild bpl with DLL in package
directory, this symptom disappeared).
5. besides copying a lot of files, I have added project\search path to almost every
DFCE subdirectories.
I can run guiclient now. Thanks and good luck
