Didn't work out.

Any system changes requires a UAC elevation, so I went ahead and made a dialog box asking for credentials that I can pass to CreateProcess with Login. So I will play nice with UAC and adhere to the purpose of it. I just hope I get it right this time.

Now I can use the luck.

Converting big integer value to string

17-Jan-12 11:13

UAC is a pain in the butt... but ultimately, it's Windows trying to recreate the same, more secure, method of operations that's been used in a lot of Linux distros for a while now. Should mean security in the long run... headaches in the short term.

You cannot convert values greater than the maximum allowed for a 64 bit integer.

Either the title or your explanation is wrong. I guess you need to convert a string representing a very big number to, well, a big integer variable.
As Jochen pointed out, we already answered your question at QA.
However, if you really don't want to use a big integer library then may you roll you own version of, say, strtoi128, i.e. a function converting the given string into the 128 bit binary representation of the number (you may mimic the method used at school to perform division).

common language runtime support error for dll

Dear Friends
I am building an application as dll. Its building with 'no common language runtime support'. But if I build with 'common language runtime support (clr)' then its giving errors. Can u tell me whats going wrong.

Here are the errors 2 linking errors

How did you create the project? I understand that you have created a native dll and enabling the clr option for the build and that is why the linker error. BTW why do you want to build the with clr enabled?

I'm not sure exactly what the issue is but I suspect you are including a library that should not be part of your DLL. This article[^] has some further suggestions that may help in the conversion process.

how can make my dll clr support. By just changing the option to clr support is not successfully building. What could be done to make it managed. Its a pure C++ MFC application. Any help would be appreciated...

You cannot convert MFC to CLR just by changing a compiler option; indeed why would you? If you want to make your code into a CLR library then you need to look through all your code to see that it is compliant.
This rather begs the question: exactly what are you trying to achieve?

Hi,
I have a text file that looks like
0 0:3649 1:1643563 2:563726 3:2358500 4:1706041 5:1399436 6:1021542 7:2612862 8:2399618 9:2177296 10:507745 11:2504905

The first element is the line number nad then it is arranged as 'attribute:value'. Due to large number of elements one line of data spans two or more lines of a text file. please note that there are no empty lines I have just done it for clarity.

how to read the first elements of each data line(in this case 0, 1,2 ,3) regardless of the the numebr of lines spanned in the text file

any help will be appreciated

thanks

So there are embedded CR/LF characters in some lines, or are you viewing it via something like Notepad that is wrapping long lines for you?

Why not check the End Of Line( "\n" ) for each line and then get the first data of each line. You may have to use a while loop for this.

when the data is organized in lines, and hence newline characters have special meaning, I find it easiest to read the data one line at the time. In C fgetline() usually does that for me. Once you have an individual line in your hands, you can scanf() it to your heart's content.
