Causes and Solutions for R6034 errors of com components written in Python

Pythoncom27.dll may not contain manifest information or contain correct manifest information, or the destruction of c ++ runtimelibrary in the system may cause this problem. to solve this problem, you can create a suitable manifest file for calling the exe file of the program, specify the correct msvcr90.dll version. for details, refer to the http://www.jb51.net/article/35219.htm

Ps: You can use mt.exe to export or merge manifest resources to exe or dll files.

Manifest method: mt-inputresource: pythoncom27.dll; #2-out: sss.txt

Merge manifest to dll:

Mt.exe-manifest MyApp.exe. manifest-outputresource: MyApp.exe; 1

Or

Mt.exe-manifest MyLibrary. dll. manifest-outputresource: MyLibrary. dll; 2

(1 for an EXE, 2 for a DLL .)

If you use c ++ to develop dll, you can also avoid this problem by replacing msvcrtd. lib or msvcrtd. lib with libcmtd. lib or libcmt. lib.

Ps: inner bowl of noodles

The test of regsvr32 pythoncom27.dll has always failed, even if the manifest information is embedded with mt, it will not work. After I change the names of pythoncom27.dll and pywintypes27.dll under the windows \ system32 directory. The original regsvr32 is by default processing the dll in the windows \ system32 directory, even if the current directory does not exist ...... Speechless. "Loaded ***. dll is finally displayed, but the dllregisterserver input point is not found .....". It seems that it is useful to embed manifest information in the dll .. Next time you 'd better write the Directory, such as regsvr32. \ pythoncom27.dll.

The python2.7 I used and the pyd file of python 2.6-3.1 so far have no manifest information according to the suggestions (requirements) of python.org. This is to better run the crt provided by python.exe at the program runtime. Pythoncom27.dll and pywintypes27.dll provided by pywin32 do not have manifest information. In this case, there is no problem in general, but the R6034 error occurs when the dll-type com component is created using python. There are two solutions: Create a manifest file for the exe that calls the com component, specify the dependency of msvcr90.dll, or embed all the used dll and pyd into the manifest information.

Why is there no one studying this information? Maybe the majority of pythoner do not play com ==||
