问题 Environment Windows 10 + python 3.6.3 64 bit (also tried 32 bit). I am a python developer trying to use COM for (nearly) the first time and hit this huge blocker. Problem I have had various errors when trying to use an IRTDServer implemented in a dll (not written by me), via either win32com or comtypes . Using win32com turned out to be more difficult. I have an included an example unittest for both libraries below. Accessing the server from Excel 2016 works as expected; this returns the

问题 I'm trying to convert a bunch of Visio files to pdf in python. I have referenced this .doc to pdf using python and written the following code: import comtypes.client as coms format=17 visio = coms.CreateObject('Visio.Application') doc = visio.Documents.Open('map.vsd') doc.SaveAs('map.pdf', FileFormat=format) gives me a TypeError: call takes exactly 2 arguments (3 given) I've been Googling and can't find the reference on how to print to pdf in Visio using python. 回答1: You should use

问题 Based on the script here: .doc to pdf using python I've got a semi-working script to export .docx files to pdf from C:\Export_to_pdf into a new folder. The problem is that it gets through the first couple of documents and then fails with: (-2147352567, 'Exception occurred.', (0, u'Microsoft Word', u'Command failed', u'wdmain11.chm', 36966, -2146824090), None) This, apparently is an unhelpful general error message. If I debug slowly it using pdb, I can loop through all files and export

问题 I would like to create a ChemDraw .cdx file from an InChI with Python. This answer gives a solution for cdx --> InChI . The minimal example below cdx_to_inchi works fine, but I could not figure out how I can get inchi_to_cdx to work. import comtypes.client as w32 def cdx_to_inchi(cdx): ChemDraw = w32.CreateObject("ChemDraw.Application") ChemDraw.Visible = False Compound = ChemDraw.Documents.Open(cdx) # opens existing file inchi = Compound.Objects.Data("chemical/x-inchi") print(inchi) ChemDraw

问题 My below code for windows authentication was working well for over a year. But for the last few days it is longer working now. I am not able to identify exact reason for that. from selenium import webdriver import time import win32com.client driver=webdriver.Chrome('D:/Software/BrowsersDriver/ChromeDriver/chromedriver.exe') driver.maximize_window() driver.get("authentication windows url") shell = win32com.client.Dispatch("WScript.Shell") shell.Sendkeys("username") time.sleep(1) shell.Sendkeys

问题 I have comtypes 0.6.2 installed on Python 2.6. If I try this: import comtypes.gen I get: Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> import comtypes.gen ImportError: No module named gen Other imports like import comtypes and import comtypes.client , however, work fine. What am I doing wrong? From the name it seems comtypes.gen is generated code? If so, do I need certain preparatory steps before importing? I'm not logged in as administrator. Could that cause code

问题 I'm trying to retrieve 2 output Arrays from an XRecord in AutoCAD 2016 using python 2.7, with comtypes imported, the first array is an array of integers (DXF Group Codes) and the second array is an array of variants (the values of XRecord). The opposite way of what this question seeks to The method of interest is GetXRecordData , which (according to AutoCAD's documentation) if successful returns None , and only accepts 2 output arguments . when I try to retrieve it with code like DxfGrCd = []
