问题 I want to get path of file "exportFile". exportFile = tkFileDialog.asksaveasfile(mode='a') If I write "print exportFile", I get: <open file u'C:/Users/Desktop/Test/aaaa.txt', mode 'a' at 0x02CB6078> But I need only path - "C:/Users/Desktop/Test/aaaa.txt".

NOTE tkFileDialog.asksaveasfilename does not take mode parameter. 回答2: Try this: exportFile = tkFileDialog.asksaveasfile(mode=

问题 I've run into an issue with the Microsoft.Win32.SaveFileDialog in our Wpf application. If the user enters an enormous file path, above the allowed maximum (I think its 255 chars?), within the SaveFileDialog then it starts to become unusable (details of this are in the code example). So as a work-around I want to close the dialogue and make them enter the file path again. However the problem is that the SaveFileDialog does not have a Close() routine or anything else that I can see to close it.

问题 I am trying to save my .NET application settings file to the user's %MyDocument%\MyApplication folder, but I don't know how to check for an existing folder\file, and create or append the folder\file on save. I don't want to open a saveFileDialog because I need the file to be in the same place on all user computers. This is what I have so far, but it isn't working. Any help would be appreciated: var saveSettings = settingsList.text; //assign settings to a variable saveSettings = Regex.Replace

This is the CreatePDF() method I'm using above: public void CreatePDF(List<System.Drawing.Image> images, string filename) { if

问题 Has anybody has done this? Navigating to a web page and pop up the save as dialog? In this way, the browser can handle the file type, html, pdf, etc... 回答1: Do you need to this to be when a FileHandler is called or on a static webpage?
