the volume name can be found out from the from GetVolumeInformation(). This function requires the drive letter not the partion number.If you manage to get the drive letter, you can get the volume name.
If there is no staright way for doing this, you can use the below method.
You can use the QueryDosDevice() function to find the diive letter from parition name. for eg consider the below code. If 'c' is the first partion, the tcDeviceName will contain \Device\HarddiskVolume1. and if you give 'd:', it will be \Device\HarddiskVolume2 and so on
TCHAR tcDeviceName[50];
QueryDosDevice( _T("C:"), tcDeviceName, 50 );
suppose you got 1 in the PARTITION_INFORMATION. then make string like "\Device\HarddiskVolume1". Now starting from A to Z, put a loop and call the QueryDosDevice. Compare the device name with the "\Device\HarddiskVolume1". If it matches, you have the drive letter.

Hello
In my current project, I am using an .ini file to store information related to the application, such as windows start up position, critical information, file paths etc. This .ini file will be easily readable and editable.
Is there a way other than .ini file and "registry" where in the applicaiton information can be stored and used in between applicaiton sesstions.
Thanx

You can dream up your own file format and manage your settings files yourself. If you do so, make sure to put the files in the %APPDATA% folder.
The registry isn't that glamorous, but it's easy to use, it's secure, and it works.

An XML file, for instance.
If you're using MFC, and you application is truly OO, then have a look at MFC Serialization http://msdn2.microsoft.com/en-us/library/6bz744w8(VS.80).aspx[^], a quite powerful tecnique.

why do you care the files are readable ? if the users modify it, it's their problem, not yours
|
|
|
|
|
The purpose of .ini file is to facilitate the user to change environment settings, with out rebuilding the application.
I don't understand what security threat you will have until and unless some passwords are present in .ini file. Anyways password can also be encripted and stored in .ini file.

i'm not the OP... are you sure you wanted to say that to me ?

|

nope. that reply was not intended to you Mr toxcct. Actually I am suporting all your suggestions, adding mine at the same time.
I know what will happen being rude to some one like you, senior member of this DB
|

|
|
You are right toxcct.
Well, no one (I am talking about non-stupid guy) is editing the Registry information unless it is clearly known to him that what exactly he is doing. Or they are taking the backup of the registry before editing.
About readability, configuration setting is not a NASA project that needs to be so secure.

Whatever you are doing, ultimately you are saving the information in the hard disk in one way or the other.
I may be a Registry Database, Sql server database, an XML file, a text file format or ini file.
I will suggest use windows registry because it is very easy to use. Don't waste your time and energy in thinking about these logics unless your requirement is completely different and registry can't serve the purpose.

You could encrypt the ini file after it's written, and decrypt it before it's read.

There's nothing necessarily wrong with INI files.
Where you put the file is an issue these days.
With a secure system, your app's directory should not be accessible to a non-administrator
user. Same with the registry, particularly the HKEY_LOCAL_MACHINE tree where you'd put
configuration settings for all users.
The recommended method these days is to use a configuration file (INI is fine, XML is fashionable)
and store it in an appdata/common appdata folder
(e.g. C:\Documents and Settings\All Users\Application Data\<company name>\<product name>\<product version>\)
There are Shell APIs available to retrieve paths of these common directories.
Your app's data folder can be set to allow access by all users at install time.
This is detailed in the Windows Logo requirements.

Seems like the template code is right.
executable can not identify the functions of dll. Did you added respective lib file Projects > Settings > Link > Object/Library modules. And include the header file and place the dll in the same path as exe.
Hope this might help
|
|
|
|
|
ive included the header file and ilb correctly. other classes imported from that dll are working .. i think the problem is exporting ..
|
|
|
|
|
I think the problem is including the template in the dll itself
A template generates code when it is instantiated. So, how are you going to put that inside the DLL?
If you are distrubuting template, write both declaration and definition in one header file, and just share it across projects. No need of dll and lib
Hope I make sense here!!!
