user interface - wxWidgets in Python -- SetContainingSizer(): Adding a window to the same sizer twice? -


i'm brand new wxwidgets. i'm tyring use elses routines provide gui data analysis tool. haven't been able contact author... i'm getting error on line 106:

pyassertionerror: c++ assertion "!sizer || m_containingsizer != sizer" failed @ /build/wxpython-src-2.9.2.4/src/common/wincmn.cpp(2275) in setcontainingsizer(): adding window same sizer twice?

the offending code looks this:

        coord_panel = wx.panel(pane, wid.any)     grid_sizer = wx.flexgridsizer(3,4)     coord_panel.setsizer(grid_sizer)     rc_x_label =  wx.statictext(coord_panel, wid.any, "x :")     rc_y_label =  wx.statictext(coord_panel, wid.any, "y :")     rc_z_label =  wx.statictext(coord_panel, wid.any, "z :")     self.rc_x = wx.textctrl(coord_panel, wid.any, style=wx.te_readonly, size=(75,-1))     self.rc_y = wx.textctrl(coord_panel, wid.any, style=wx.te_readonly, size=(75,-1))     self.rc_z = wx.textctrl(coord_panel, wid.any, style=wx.te_readonly, size=(75,-1))     empty_label = wx.statictext(coord_panel, wid.any, "  ")     self.edit_cam_btn = wx.button(coord_panel, -1, "edit", size=(50,-1))     grid_sizer.addmany([(rc_x_label, 0, wx.align_center_vertical | wx.align_right),                         (self.rc_x, 0), (empty_label, 0), (empty_label, 0),\                         (rc_y_label, 0, wx.align_center_vertical | wx.align_right), \                         (self.rc_y, 0), (empty_label, 0), (self.edit_cam_btn, 0),\                         (rc_z_label, 0, wx.align_center_vertical | wx.align_right), \                         (self.rc_z, 0), (empty_label, 0)])

it's generating error on grid_sizer.addmany line. see issue?

thx!

the code incorrect, can't add same empty_label control multiple times sizer. need create new control (which luckily not difficult empty label) every time.

a better idea avoid using empty labels , use spacers or intra-row gap instead require more changes code.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
