Re: getting windows system directory joshfl23-Jan-03 3:25 joshfl 23-Jan-03 3:25  thanks todo.... :: insert inpirational text here :: CString parameters r i s h a b h s22-Jan-03 18:04 r i s h a b h s 22-Jan-03 18:04  dear all, how can i pass CString objects in API functions which expect:- LPCTSTR LPCWSTR LPCTSTR LPTSTR -> is there any other way than CString::GetBuffer LPWSTR PCSTR thanx Re: CString parameters Christian Graus22-Jan-03 18:15 Christian Graus 22-Jan-03 18:15  Where you want a wide string, use _bstr_t, the constructor builds an object which contains both a wide and narrow string, with operators for both. That may well work for all the things you list. I think it's defined in comdef.h, or somesuch.

Re: CString parameters Christian Graus22-Jan-03 20:59 Christian Graus 22-Jan-03 20:59  rishabhs wrote: but is the method safe and effective? Gosh you're a worry wart !!! Yes, it's fine. The constructor builds a class, that class passes the required result to the function and on return the class destructor cleans up after itself. Windows is full of string conversion routines, but I find the _bstr_t method nice and easy.

When you know how recurrent these posts about strings are, that's a complete shame each person posting in the VC++ forum is not offered a poll before they really get to the posting form, and that would go like this : - question 1 : is your question about strings (translate that one to indian too) ? If answer is yes, throw the Dunn tutorials to his head. Otherwise, - question 2 : are you sure your question is not related to characters or the CString class ? (please note the irony ) - question 3 : in case your question has to do with a LPSTR topic or something like that, then please consider looking those articles : 1[^] and 2[^].

I've recently heard that Named Pipes are no longer supported in Windows XP or that it will be gradually phased out in the long run. I'm wondering if this is truly the case. I've referred to the MSDN documentation for Named Pipes and noted that it is supported in XP and there is no mention of it becoming obsolete. I personally do not think Named Pipes will become obsolete anytime in the future but has anyone vaguely heard of this possibility ? Thanks, All, Bio.

And yes it's event based. It doesn't write Xml though. (MSXML 4.0 is f***ing fast either, but the SDK has limitations, and it's of course full of proprietary interfaces and behaviours).

Relative Path not available in startup fordge22-Jan-03 15:21 fordge 22-Jan-03 15:21  I initially started this message thread as I had a problem getting the ado connection at startup.... i had written the exe path in a key in registry "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\\Run"...though the exe startsup an ado connection error is thrown if ado connection is tried in InitInstance of the app ive finally got it right..consider the following code ----------------------------------- CoInitializeEx(NULL, 0x02); try{ _ConnectionPtr mpDBConnection; mpDBConnection.CreateInstance(__uuidof(Connection)); HRESULT hRes=mpDBConnection->Open(_T("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=database\\TrialDB.mdb;Persist Security Info=False"),"","",adConnectUnspecified); CStartUpDlg dlg; m_pMainWnd = &dlg; ... ... .. ----------------------------------- this works fine when normally executed and the database connection is ok. however in startup when saying "database\TrialDB.mdb" instead of refering to the relative path of the application it assumes it as being in "c:\" drive..... and therefore looks for the database in "c:\database\TrialDB.mdb" .. and obviously as there is no database there the connection fails. however if the code is changed tohaving the follwoing lines occure before the connection is opened like below ----------------------------------- CoInitializeEx(NULL, 0x02); try{ CStartUpDlg dlg; m_pMainWnd = &dlg; _ConnectionPtr mpDBConnection; mpDBConnection.CreateInstance(__uuidof(Connection)); HRESULT hRes=mpDBConnection->Open(_T("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=database\\TrialDB.mdb;Persist Security Info=False"),"","",adConnectUnspecified); ... ... .. ----------------------------------- the conection works fine in startup as well.. but unfortunately as i need to do the database connection before I create the dialog object..... the question persists... 1.Why cant i get the relative path in startup???? 2.Please suggest an alternative solution to get the relative path.... i mean besides using get CurrentDirectory() and that kind of stuff Consider for example when we create a shortcut we can specify a 'start in' directory and all relative paths refer to this strt in directory right?? is there anywhere i can specify such a 'start in' directory for an application in registry!!! if there is any other method to get the relative path of the app please tell me... Re: Relative Path not available in startup Chris Richardson22-Jan-03 19:16 Chris Richardson 22-Jan-03 19:16  If you want to get the path of the .exe at runtime, take a look here: http://www.codeproject.com/cpp/cppforumfaq.asp#win_exepath[^] You can strip off the exe name, and then you have the directory the program is running from. Chris Richardson Programmers find all sorts of ingenious ways to screw ourselves over. - Tim Smith Re: Relative Path not available in startup fordge23-Jan-03 14:08 fordge 23-Jan-03 14:08  thankx but no thankx cause one i already said i didnt need more apis like GetCurrentDirectory() hells there s countless methods where i can get the app path and then go on for concatenating and secondly and more importantly my primary question as to why the relative path isnt recoognised at startup remains unanswered. i was thinking more in lines of as how the application framework finds its the current directory..... if there must be some variable on m_pMainWnd or soemthing setting that would men lesser work and a more efficient solution than changing of code for the concatenation... for example app has m_pszHelpFilePath to set the help file path there must be something where the path is stored so that the exe can refer to it when a relative path is called if im wrong pls correct me? and pls tell me whythe relative path isnt recoognised at startup remains unanswered.
