C++ get APPDATA folder path?

[ProGamerForLife]

How would I get the appdata path and return it to a string so that I could use it while trying to download a file using the code below

HRESULT hr = URLDownloadToFile ( NULL, _T("http://www.codeguru.com/forum/showthread.php?threadid=463496"), _T("I want to use the appdata path string here"), 0, NULL );

Any help is appreciated.

You must be registered to see links

#include <stdlib.h>
#include <stdio.h>

int main(int argc, char** argv){
	char* appdata = getenv("APPDATA");
	printf("Appdata: %s\n",appdata);
	return 0;
}

I need it to be the path aswell as a file name at the end so like

appdata + "\test.html", but i get

1>c:\documents and settings\mike\my documents\visual studio 2010\projects\mydlll\mydlll\maindll.cpp(33): error C2110: '+' : cannot add two pointers
1>c:\documents and settings\mike\my documents\visual studio 2010\projects\mydlll\mydlll\maindll.cpp(34): error C2065: 'Lappdata' : undeclared identifier

when i try to compile

Learn C++.

I'm coming from a C# background & Java, C++ syntax is impossible to read, can you just fill me in on how to add the "\\test.html" to the end of the appdata char ;p..

 

[kronic23]

char* appdata = getenv("APPDATA");
strcat(appdata, "\\test.html")
printf("Appdata: %s\n",appdata);

EDIT: oops

Learn to Google then.

Create a new string with the char*. The string class has the + operator you're looking for.

I end up getting an error that LAPPDATA is undeclared or something (Appdata = the string).

No way to help you there not knowing what your LAPPDATA is. Try declaring it.

Be more specific in what exactly you tried and what exactly the error is.

 

[ProGamerForLife]

char* appdata = getenv("APPDATA");
strcat(appdata, "\\test.html");
    HRESULT hr = URLDownloadToFile ( NULL, _T("http://www.codeguru.com/forum/showthread.php?threadid=463496"), _T([COLOR="Red"]appdata[/COLOR]), 0, NULL );

and it errors up saying

1>c:\documents and settings\mike\my documents\visual studio 2010\projects\mydlll\mydlll\maindll.cpp(37): error C2065: 'Lappdata' : undeclared identifier

You can't (and no reason you should) use the _T macro with variables.

Here's what I use...

CoInitialize(0);

wchar_t AppDataFolder[MAX_PATH];
SHGetFolderPath(0, CSIDL_APPDATA, 0, SHGFP_TYPE_CURRENT, AppDataFolder);
wcscat_s(AppDataFolder, L"\\test.html");

If you don't have a good C++ compiler like vs2010, you might not have that particular wcscat_s override - change it to wcscat_s(AppDatafolder, MAX_PATH, L"\\test.html");
