"Converting string retrieved from windows registry to integer"

[harsh_2961]

hi, i am using Windows registry to store an integer value on closing of my dialog and running the application again i am retrieving this value.. this retrieved as string and i tried using "atoi()" to convert but iis giving following error. "'atoi' : cannot convert parameter 1 from 'CString' to 'const char *'" and the lines while retrieving the string are.. System::String* valueNames[] = keySoftware->GetValueNames(); for( int i = 0; i < valueNames->Length; i++) { CString strValue = static_cast(keySoftware->GetValue(valueNames[i])); .... .... ....

I will let you know i a while:laugh:

have you defined _UNICODE in your project settings?

Do this way, Suppose strKey contains the registry value it read.

int nTemp = atoi (strKey.operator LPCSTR ());

This will surely work.

Do this way, Suppose strKey contains the registry value it read and it is a CString object.

int nTemp = atoi (strKey.operator LPCSTR ());

This will surely work.

i wonder why you needed atol here. If using MC++, then you can use Convert::ToInt32 function for this purpose, instead of mix of all these things.

System::String* valueNames[] = keySoftware->GetValueNames();
for( int i = 0; i < valueNames->Length; i++)
{
int nValue = Convert::ToInt32(valueNames[i]);
...
}

And use <pre> tags while posting code.

Never call an operator this way, this is just uggly. You can simply do that: int nTemp = atoi((LPCSTR)strKey); But I don't think it will work because if the cast was possible it would have been implicitely done already and you wouldn't have an error.
