Hi,try this! char* wx2char( char* cstring,const wxString& wxstr,const wxMBConv& conv ) { cstring = (char*)malloc( sizeof(char)*( strlen( (char*)(wxstr.mb_str(conv).data()) )+1 ) ); return strcpy(cstring, (const char*)wxstr.mb_str(conv)); } and the conv I set to wxConvUTF8. My project charset is unic...

Hi, guys!
Is there a way to remove the file to trash?(Windows && MacOS)

Waiting for your reply.....

bool UTF82WC( const std::string & source , std::wstring & outstr ) { wxMBConvUTF8 conv; size_t nRealSize; wxWCharBuffer theBuffer = conv.cMB2WC( source.c_str() , source.size() , &nRealSize ); if( nRealSize ) { outstr.assign( theBuffer.data() , nRealSize ); return true; } else { return false; } } bo...

Hi everyone! I download the latest Source Archives,and complied it. and I found a strange thing in the dataview demo. dataview.cpp m_ctrl[1]->AppendTextColumn("editable0", 0, wxDATAVIEW_CELL_EDITABLE, 120); m_ctrl[1]->AppendTextColumn("editable1", 1, wxDATAVIEW_CELL_EDITABLE, 120); m_ctrl[1]->Append...

wxBufferedPaintDC:
Note that at the time of writing,
using buffering with wxBUFFER_CLIENT_AREA does not work with scaling
(SetUserScale).

（mark it） && （support you）！

you can try the wxWidgets-2.8.10 or 2.8.8
It seems that 2.8.9 has a problem with PaintDC.

I have another way to scale the image. Thanks sis! bool ScaleImageByDC( const wxImage* pImg,double xScale,double yScale,wxBitmap& destBitmap ) { if (!pImg || !pImg->IsOk()) { return false; } size_t ow = pImg->GetWidth(); size_t oh = pImg->GetHeight(); destBitmap = wxBitmap( ow*xScale,oh*yScale ); wx...

Is anyone have a try or test？

SetIcon(wxICON(APPICON));

And in the rc,you can change the ico to your ico

APPICON ICON "res\\yourico.ico"

Can you show precisely what happens, i.e. a debugger trace? And mention your platform, wx version, etc. the pImg->IsOK() is true; wxWidgets version is 2.8.10, OS is WindowsXP Physical memory is 2048M I was in DEBUG . And the image I have upload, you can download it. http://www.go2upload.com/file/3/...

hi ,try this ! In Unicode build

the code is here: (In Unicode build) if( pImg->IsOK() ) m_Image = pImg->Scale(w,h); //the program will be crash,it was shown in Scale fun,line 495,in the image.cpp the size of pImg is 40000*2111, and the w,h is ( 146,8 ) when the w,h is (3000,2000),the program is ok, Is the size too small to scale? ...

Thanks catalin!
I have change the bufferDC to wxPaintDC.
