first of all thanks to look into my problem...
The Flow is-->
let lpTextPtr is of type LPSTR;
I write -->
lpTextPtr[0]='T';
lpTextPtr[1]='\0';
lpTextPtr[2]='e';
lpTextPtr[3]='\0';
lpTextPtr[4]='x';
lpTextPtr[5]='\0';
lpTextPtr[6]='t';
lpTextPtr[7]='\0';
lpTextPtr[8]='\0';
lpTextPtr[9]='\0';
and send lpTextPtr to Unicode Supported DLL.
Where lpTextPtr is assigned to EditBox of that unicode Dialog.(works fine)
In the Dialog(of DLL) I select Language the and write a any Text in editBox. The editBox's text is assigned to lpTextPtr.(works fine).
and control leaves DLL and backk to mai workspace.
Now Here I want to store lpTExtPtr(say in CListCtrl)...
it cant persist its value in nonUnicode invironment.
how to convert Unicode to normal string and then normal string back to Unicode is my problem...

Have a look at the following functions in msdn.

Hello
I've been using the API GetCurrentDirectory() to retrieve the current working directory of my application. The code snippet is below:
char szPath[100];
GetCurrentDirectory(sizeof(szPath),szPath);
The above function works fine if the path of the current directory is 100 chars. But what if the path of the current directory is more that that ? My app would crash rite ?
So is there any way to make the size of szPath dynamic, such that from wherever our app gets runned (watever be the path length) the app shouldnt crash.
Thanx
|

|

try with this one.
char szPath[MAX_PATH];
GetCurrentDirectory(sizeof(szPath),szPath);

in the NTFS format, the maximum length of a file name or directory name can be up to 255 characters. So u can use char szPath[256];
or u can use
char szPath[MAX_PATH];// MAX_PATH is declared in windef.h

Do you mean to say that a file name / directory name (starting frm its root) cannot be more than 256 chars ? What if its more than 256 chars ?
Thanx

No , You can't. It includes full path. It can be limited up to 256 chars.

consider the following case.
He created a folder having name of 200 chatacters. Inside that folder he create another folder with 200 chatacters. then he put the exe in that folder and executed. The MAX_PATH wont work na?

He can't. He can create folder upto 55 characters then.(i'm assuming its on root folder). In other words
c:\[200 chars]\[then this name can be upto 55 chars]\[still there are some chars left to reach 256, then file/folder can be created otherwise not].
So in any case, full path name will not exceed _MAX_PATH.

i checked.. u r right

I can create a Maximum path upto 247 chars only including Root Directory.
C:\suniljampasuniljampasuniljampasuniljampasuniljampasuniljampa\suniljampasuniljampasuniljampasuniljampasuniljampasuniljampa\suniljampasuniljampasuniljampa\suniljampasuniljampasuniljampa\suniljampasuniljampasuniljampa\suniljampasuniljampasuniljamp
But MAX_PATH is 256, and you mentioned that excluding C:\, one can create 255 chars. But I cannot create more than 247 char folder including C:\.

Interesting. Might be some chars are used by OS. But, no idea about it.

Yes, I experienced similar behaviour in the morning, while answering this thread.
Probably, its not considering its child folder's\file's name, wile allowing to name folder.

Can anybody clarify whether MAX_PATH can be used for FileName Length or PathName Length???

Full path name .

No, for maximum file length _MAX_FNAME is used.

CString CListCtrl::GetItemText(int nItem, int nSubItem) const in the ...Microsoft Visual Studio\VC98\MFC\SRC\WINCTRL2.CPP file
