@ limburger Parsing Text File Contents

Sorry I had to start a new thread. There's a forum bug which blocks me from replying in the original thread:
http://www.cplusplus.com/forum/windows/139091/


I was hoping to find a complete compilable, runnable program, such as this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
#include <windows.h>
#include <iostream>
#include <fstream>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) 
{
    std::ifstream ifs("E:\\StateFile.txt");
    
    if (ifs.is_open())    
        MessageBoxA(NULL, "StateFile Opened", "Information", MB_ICONINFORMATION);
    else
        MessageBoxA(NULL, "StateFile could not be opened", "Error", MB_ICONERROR);
     
    return 0;
}


Now that code works ok. However, If I add an extra line, like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
 
#include <windows.h>
#include <iostream>
#include <fstream>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) 
{

    HANDLE StateFile = CreateFile("E:\\StateFile.txt", GENERIC_ALL, 0, NULL, 
        OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, SECURITY_ANONYMOUS); 

    std::ifstream ifs("E:\\StateFile.txt");
    
    if (ifs.is_open())    
        MessageBoxA(NULL, "StateFile Opened", "Information", MB_ICONINFORMATION);
    else
        MessageBoxA(NULL, "StateFile could not be opened", "Error", MB_ICONERROR);
     
    return 0;
}
then it will fail. There's no reason to use both the Windows as well as the C++ stream to access the file. The CreateFile() here grabs exclusive control of the file, thus preventing any other access.

hmm I took out the statefile script and it still failed on reboot. did you want me to post the entire code? Its about 300 lines haha.

I was hoping you would post the entire code, with all the non-relevant parts removed. As it is, the code which I'm running is not the same as the code which you are running, so there's little chance of finding a solution.

hmm did you maybe want to pm me your email address and i can send you the .cpp? I don't want giving you anything that might be important, up to you otherwise I can post the script in here.

actually I tested it a few more times after that and it is opening the statefile and reporting the values so I think that part is good. Is there a way that following it reading those values I can have it go to the CASE ID_INSTALL:? Or is there some other way I should have it initilize installing again?

I'm glad that the original problem is apparently resolved.

As for the follow-up question, i feel I'm out of my depth here. Either my knowledge of Windows software development isn't great enough (others here may be better placed), or a lack of a clear view of the code as a whole leaves me a bit out of my depth here. I was certainly willing to follow up on the original question, but maybe it's time for me to withdraw, rather than promise something I can't deliver.
