I am trying to convert this to c# but i am not winning.
Code: Select all
for (var i = 0; i < plainText.length; i++)
mNumber += (plainText.charCodeAt(i) * (i + 1)) ^ (i + 1);
Code: Select all
for (var i = 0; i < plainText.length; i++)
mNumber += (plainText.charCodeAt(i) * (i + 1)) ^ (i + 1);
Code: Select all
string text = "Blahblahblah";
int x = text[2]; // Or whatever...

lol, good you know, i have a project i am busy with and work with hikvision everyday.GDI_Lord wrote:Now why do you need a C# version of the admin password reset tool for Hikvision's cameras?
According to him/her, create a .html file with the following text inside and then just double click on the file. Have you tried doing this? Then there is no need to convert from JS to C#.bp2008 wrote:[Here] is the complete source code which you can write to a .html file on your computer, allowing you to use it offline.

<div><h2>Hikvision Camera Password Reset Utility</h2></div>
<div class="description">This tool will generate a <b>password reset code</b> which you may use to reset a forgotten admin password for a Hikvision camera.</div>
<div class="label">Enter your camera's complete CASE SENSITIVE serial number, as seen in the <a href="http://www.google.com/search?q=Hikvision%20SADP">Hikvision SADP</a> tool:</div>
<div class="input"><input type="text" id="serialNumber" style="width: 100%" placeholder="Hikvision Camera Serial Number" /></div>
<div class="label"><b>Important:</b> The date you enter below much match with the camera's clock. <b>Most likely it is not today's date!</b> To find out what date your camera thinks it is, power cycle your camera, give it time to boot up, and then refresh your camera list in SADP and check the Start Time column.</div>
<div class="label">Enter the <b>4 digit</b> year the camera thinks it is:</div>
<div class="input"><input type="text" id="year" style="width: 20%" /></div>
<div class="label">Enter the <b>2 digit</b> month the camera thinks it is:</div>
<div class="input"><input type="text" id="month" style="width: 20%" /></div>
<div class="label">Enter the <b>2 digit</b> day the camera thinks it is:</div>
<div class="input"><input type="text" id="day" style="width: 20%" /></div>
<div class="label">Your <b>password reset code</b> will appear below.</div>
<div id="output"></div>
<div class="label">The code must be entered into the <a href="http://www.google.com/search?q=Hikvision%20SADP">Hikvision SADP</a> tool in the <b>Serial code</b> box (called <b>Security Code</b> in later SADP versions). The camera will compare its internal date and time with the date and time you have entered above. The Serial Number and date much match perfectly or else the code will not work.</div>
