C ++（不使用MFC）检查ini读取值是否为空

Question

I am having a little trouble getting the my program to check whether or not a .ini file is empty or contains the path to a webpage.

My .ini file:

[WEB]
Location =

The following is my code. It will not enter the if statement and show the Dialogbox:

GetPrivateProfileStringA("WEBSERVICES", "Location", "none set", webLocation, sizeof(webLocation), pathStr);

    if (webLocation == "1"){
        DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);
        EnableMenuItem(hmenu, ID_WEBSERVICES_RUN, MF_GRAYED);
        }

Any help on this issue would be appreciated.

Regards -Dan.

Answer 1

The if condition is incorrect, use strcmp() to compare char arrays:

if (0 == strcmp(webLocation, "1")){

This:

if (webLocation == "1"){

compares the address of webLocation to the address of the string literal "1" , which always will be false (in this case).

Note that the section name WEB does not match that specified in the call to GetPrivateProfileStringA() .
