Hi, <div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I need some guidance as am stuck at a place. How should I replace 'erase' using guidelines given under <a href="https://wiki.documentfoundation.org/Development/String_Classes" target="_blank">https://wiki.documentfoundation.org/Development/String_Classes</a>. If I try to fit 'replaceAt' in place of 'erase' in the line bolded below: SdStyleSheet* SdStyleSheet::GetRealStyleSheet() const/home/elixir/lo/sd/source/core/stlsheet.cxx:429:73: { String aRealStyle; String aSep( RTL_CONSTASCII_USTRINGPARAM( SD_LT_SEPARATOR )); SdStyleSheet* pRealStyle = NULL; SdDrawDocument* pDoc = ((SdStyleSheetPool*)pPool)->GetDoc(); ::sd::DrawViewShell* pDrawViewShell = 0; ::sd::ViewShellBase* pBase = dynamic_cast< ::sd::ViewShellBase* >( SfxViewShell::Current() ); if( pBase ) pDrawViewShell = dynamic_cast< ::sd::DrawViewShell* >( pBase->GetMainViewShell().get() ); if (pDrawViewShell && pDrawViewShell->GetDoc() == pDoc) { SdPage* pPage = pDrawViewShell->getCurrentPage(); if( pPage ) { aRealStyle = pPage->GetLayoutName(); // cut after seperator string aRealStyle.Erase(aRealStyle.Search(aSep) + aSep.Len()); } } it will give me error (if I do : aRealStyle.replaceAt(aRealStyle.indexOf(aSep) + aSep.getLength());) Reason: replaceAt defined as: rtl::OUString rtl::OUString::replaceAt(sal_Int32, sal_Int32, const rtl::OUString&) const (candidate expects 3 arguments, 1 provided) error: no matching function for call to ‘rtl::OUString::replaceAt(sal_Int32) My question is, what should I pass inside the replaceAt() parameters/arguments?

I am happy to see you actively work on Patch 38838 :) and am also working on the same patch since last few days and trying hard to get touch with it comfortably. However, things are not going in their best way. Can you help me with fixing the same bug and getting me more comfortable with it. What is the way to replace String with OUString. Is it anywhere I see them, I just need to replace them or there are other factors also I need to take them under consideration? I shall be grateful to you for being patient and helping/guiding me for the same :) Waiting for your earliest reply Thanks and Regards Prashant Pandey </blockquote></div> </div></div>Hi Prashant, Welcome on board! The more people work on this bug the faster it will be solved and it is a big one. I suggets you take a look at this page: <a href="https://wiki.documentfoundation.org/Development/String_Classes" target="_blank">https://wiki.documentfoundation.org/Development/String_Classes</a> It outlines how to replace String/UniString/XubString (the 2 latter are #define's of String) with OUString. You can also take a look at the doc for OUString (<a href="http://api.libreoffice.org/docs/cpp/ref/classrtl_1_1_o_u_string.html" target="_blank">http://api.libreoffice.org/docs/cpp/ref/classrtl_1_1_o_u_string.html</a> ) and OUStringBuffer ( <a href="http://api.libreoffice.org/docs/cpp/ref/classrtl_1_1_o_u_string_buffer.html" target="_blank">http://api.libreoffice.org/docs/cpp/ref/classrtl_1_1_o_u_string_buffer.html</a> ). Since OUString is immutable it is to be used when a String does not change or not much, while OUStringBuffer is to be used to build an OUString. I suggest you read these pages and take a look at previous commits on <a href="http://cgit.freedesktop.org/libreoffice/core/log/" target="_blank">http://cgit.freedesktop.org/libreoffice/core/log/</a> where you can do queries to find the relevant commits. Also I suggest you subscribe to the developer's mailing list and ask your questions regarding this bug there. Thanks and good luck!
