WebBrowser (MSIE) - Capture JS Errors using Exec of IOleCommandTarget

阅读更多关于 WebBrowser (MSIE) - Capture JS Errors using Exec of IOleCommandTarget

问题 I need to capture script errors in MS IE activex control (dubbed as WebBrowser). As I see it, this is done by implementing the IOleCommandTarget interface in my application and listening for OLECMDID_SHOWSCRIPTERROR. I did the above and I know it works since my Exec method is called, but here's the problem; it is only called once with nCmdID being set to $00000037 ( OLECMDID_PAGEACTIONBLOCKED ), but never $00000028 ( OLECMDID_SHOWSCRIPTERROR ). In order to trigger that error, I've been using

阅读更多关于 Python and Excel: Overwriting an existing file always prompts, despite XlSaveConflictResolution value

问题 I'm using the Excel.Application COM object from a Python program to open a CSV file and save it as an Excel workbook. If the target file already exists, then I am prompted with this message: "A file named '...' already exists in this location. Do you want to replace it?" That message comes up despite the fact that I have set the XlSaveConflictResolution value to xlLocalSessionChanges, which is supposed to automatically overwrite the changes without prompting -- or so I thought. I'm using

There is an InlineData property but generally the class is undocumented and I don't know what this property does. Can it be done at all? Thanks F 回答1: I assume what you are wanting to do is initialize this in C# rather than in Flash itself. It can be

SaveAs vs SaveAs2 in the Microsoft Office Word object model

阅读更多关于 SaveAs vs SaveAs2 in the Microsoft Office Word object model

问题 It looks like SaveAs has gone away in Office 2010 in favor of SaveAs2. What is going on here? Are there any important differences between the two? My fix has been to check for SaveAs2 first, and then fall back to SaveAs. Is this reasonable? 回答1: It hasn't gone away, you've just got another way to save the document. Save2() takes an extra argument, CompatibilityMode. If you don't care about the compatibility mode then just keep using Save(). If you do then check Application.Version to verify

问题 Has anyone found and used an alternative to the Microsoft Webbroswer ActiveX control with any success? The open source Firefox ActiveX version seems to be a dead project development wise and based on an old Firefox version. 回答1: Give a look to the GeckoFX Project, an open-source component for embedding Mozilla Gecko (Firefox) in .NET applications. Written in clean, fully commented C#, GeckoFX is the perfect replacement for the default Internet Explorer-based WebBrowser control. (source:
