Aint you wasting your time a little bit, trying to explain details when you know Dunn did a couple tutorials about it ? 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[^].

thanx .S.Rod. for the hammering!
i had no knowledge about the tutorials, that's why i thought i could get some helping hand in the forum.
anyways thanx for the links u've shown me! i think they'll help my cause.
i think u were sarcastic in the reply!
i could'nt understand some of the remarks!
thanx

Good point, I must admit I forget about those as well.

I want to get every HTML page when IE load it, any idea?
Thank you.

Either you can Embedd Web Browser component and load respective html page or
use following in a DialogBox for invoking Html page:
HWND h = FindWindowEx(NULL,NULL,NULL,"Microsoft Internet Explorer");
ShellExecute(h,"open","http:\\\\www.funducode.com",NULL,NULL,SW_SHOWNORMAL);

Hello Dear All,
I've been doing Windows NT 4.0 development since 1997 and I'm relatively new to Windows XP. 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.

Hi guys,
I've a dial up connection available on a pc to which I'm connected via LAN. I want to connect to internet using this dial up connection. How can I do that? Is it possible to invoke that dial up connection through my program also.
Thanks

im looking for the fastest, easiest, (hopefully very W3C conformant) XML parsing/writing library -- preferably support for event-based parsing
i've tried microsoft's MSXML but it's unbelievably hard to use with all the COM interfaces and stuff it gets annoying
thanks for the help
- Roman -

|
|
|
|
one of the fastest is expat[^] (James Clark, W3C). 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).

Does anyone know of universal naming convention (UNC) path?
thank you
|
|
|
|
|
UNC paths AFAIK, start with "\\", such as "\\server\share\". Take a look in the MSDN for further information.

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...

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.

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.

Well, no matter which route you go, you will almost undoubtably end up using GetModuleFileName (directly or indirectly). CWinApp is even using it to format the m_pszHelpFilePath (take a look in MFC sources).
Why isn't the relative path recognized at startup? Well, it is being recognized. It's just that it's being recognized as being relative to the "C:\" path, instead of the path your app resides in. Putting relative paths in your program and depending on Windows to set your directory for you is never a good idea, and the best way to not do it, is probably to use GetModuleFileName. It will be all of 6 lines of code, and you will remove the risk of not finding your database (unless the database gets deleted).

Refer to the documentation on CreateFile or the Open method of the database connection object for a list of paths that are searched when you use a relative path name.

Why does the following code show the Same Dialog Box twice? The code for the Dialog boxes in inside a dll and the call to the CreateCharacter() is called from the main application. The problem is that the application only shows the first dialog box, even though the "Testing" message box does appear. This tells me that the application is call the correct class, but not showing the correct dialog box.
Thanks for any help you can give.

Sorry for so much code, but I couldn't figure out how to attach the files to my message.  The two ids IDD_NEWCHAR1 and IDD_NEWCHAR2 are defined in resource.h as 129 and 130 respectively. If someone can point out how to attach the files I would be more than happy to attach the code to make it easier to read.
Thanks again for the help,

Firstly, its not possible to attach a file to a message on the CP boards.
As a possible solution, how is the DLL that has these dialog loaded? Is it dynamic? If it is, you may have to use the AFX_MANAGE_STATE() macro or the AfxSetResourceHandle() command to make sure that the correct resources are used when the DoModal() call is performed. Check you application that uses the DLL and see whether it has matching dialog resources using the same resource ID values (i.e. 129/130 as mentioned in the other reply).
