Re: Memory Tracking Chris Losinger8-Jul-02 11:48 Chris Losinger 8-Jul-02 11:48  if you're on NT/2K/XP, you can try calling _heapmin somewhere in your app. sometimes that will force the OS to minimize your app's heap (really free'ing memory you think you've already free'd, but which the OS hasn't given back to the general pool). sometimes it has no effect at all... -c Being just contaminates the void.   --Robyn Hitchcock Image Processing - easy, like Sunday morning. STL unicode/ANSI conversions 8-Jul-02 5:54 8-Jul-02 5:54  Anyone here knows of a site that has the details of how to convert wstring to strings and vice versa in STL. Apparently, there are a couple of different ways of doing this. I am not sure if VC6 supports them, but anyhow, i would appreciate any hints. thanks Re: STL unicode/ANSI conversions Michael Dunn9-Sep-04 7:22 Michael Dunn 9-Sep-04 7:22  Check out The Complete Guide to C++ Strings, Part II - String Wrapper Classes[^] --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- If my rhyme was a drug, I'd sell it by the gram. Help needed, ADO Recordset - urgent 8-Jul-02 5:32 8-Jul-02 5:32  I'm writing a data server. In which, I have a Server, which has methods: FirstPage, PrevoiusPage, NextPage, LastPage, Insert, Delete. One page is 20 rows set in the server. In the client, I have a client rowset class, which will cache all the rows it fetched so far. Say, invoke server's FirstPage to get 1st 20 rows, call Nextpage to get the NextPage, and so on. All the rows got will put in internal cache in client rowset, and navigation (first, prev, next, last) are so far so good. However, when i do insert in 10th row in client side, i created an instance, and invoke server side's Insert too. However, I'm not sure WHICH PLACE the ROW WILL be. Therefore, I can't synchronize the rowset. Can anyone tell me if there's any standard for insert positioning, and how to synchronize it ? I've to finish it pretty soon, or i'll be fired. Please help me. Renaming registry sagmam8-Jul-02 5:10 sagmam 8-Jul-02 5:10  Is there any way to rename a regsitry key that already exists? The same way a user can do when he presses F2 while in the Registry Editor? I could not find any Win32 API function that does this, nor an automation interface of regedit... /=/=/=/= Deus /=/=/=/= Re: Renaming registry DanielP8-Jul-02 5:31 DanielP 8-Jul-02 5:31  There is no such way. Regedit at first creates new key, copies all subkeys, and then deletes old key. Re: Renaming registry sagmam8-Jul-02 5:43 sagmam 8-Jul-02 5:43  I find it hard to believe since it is done instantaneously - even if the renamed key contains a full hierarchy. Try it yourself: create some huge subtree and then rename its root key. You'll see that it happens immediately. /=/=/=/= Deus /=/=/=/= Re: Renaming registry DanielP8-Jul-02 6:04 DanielP 8-Jul-02 6:04  When I do that my program works very fast too )) ..And why you suppose it works slowly? Most of Registry is cached in memory therefore it's just memory copying. But if you don't believe me, run Regmon and see for yourself STL Brian Azzopardi8-Jul-02 5:06 Brian Azzopardi 8-Jul-02 5:06  Hi all, Has anybody had any problems using the SGI STL with VC6? bibamus, edamus, cras moriemur [eat, drink, for tomorrow we die] add-in for MS VS .NET in C++ 8-Jul-02 5:04 8-Jul-02 5:04  How do I creata an add-in for Visual Studio .NET in C++. I mean I create a project(Other Projects/Extensibility Projects/Visual Studio .NET Add-in) and when I try to compile it, it says: e:\trash\MyAddin1\stdafx.h(45) : error C3506: there is no typelib registered for LIBID '{AC0714F2-3D04-11D1-AE7D-00A0C90F26F4}' e:\trash\MyAddin1\stdafx.h(45) : fatal error C1104: fatal error importing libid: 'AC0714F2-3D04-11D1-AE7D-00A0C90F26F4' Can anyone help me ? Passing Strings encoded BASE64 in XML 8-Jul-02 5:04 8-Jul-02 5:04  I want to use XML to transport some data across HTTP protocol. When text in some element contains US ASCI characters then all is OK. But when some language- specific characters appear i get error. I want to encode contents of some elements (these that contain these unfortunate characters) to BASE.64. when I do the following, I get error. _variant_t var_val=GetSomeText_WithStrangeChars() ..check errorcodes... pNewNodeOut->put_dataType(L"bin.base64"); ..check errorcodes... //ok it works so far pNewNodeOut->put_nodeTypedValue(var_val); //HERE CRASH //It is here where HRESULT is E_FAIL The first question is: What to do to avoid error, and to sucessfully put value of _variant_t (containing BSTR) into element whose type is set to bin.base64 ? The last question is: Shall I be able to automatically get the value of the element without explicit converting it from BASE.64 ? I mean : Shall MSXML parser do the conversion automatically for me when I will call nodeTypedValue property ? Thanks Michal Januszczyk ShellExecute() briefcase8-Jul-02 4:53 briefcase 8-Jul-02 4:53  I'm sorry for the generalization, but I need help using the ShellExecute() function (to launch a .hlp file). ShellExecute( ?, "open", "Helpfile.hlp", NULL, ?, //dir SW_SHOW ); I put a '?' where I don't know what I should put The first is the window handle thingy, I really don't want the opened file attached to anything, how do i do this? The second ? is the directory... I have no idea what to set this too. If it's the programs current dir, how do i find that? Thanks Re: ShellExecute() DanielP8-Jul-02 5:24 DanielP 8-Jul-02 5:24  Set NULL. To know current dir - invoke GetModuleFileName() Re: ShellExecute() Rickard Andersson208-Jul-02 5:24 Rickard Andersson20 8-Jul-02 5:24  briefcase wrote: The first is the window handle thingy, I really don't want the opened file attached to anything, how do i do this?

ShellExecute( NULL, "open", "myhelp.hlp", NULL, NULL, //dir SW_SHOW ); myhelp.hlp exists in the same dir as the calling program. Re: ShellExecute() DanielP8-Jul-02 6:26 DanielP 8-Jul-02 6:26  that's right code. And what is happend then?

To get the current directory (if you need to), use the GetCurrentDirectory Win32 function.
