 |
|
We're almost sure that we are going to buy this tool. It looks really great, with this price tag noone can beat it. We're doing some production tests to be sure that what we need can be done without problems and some issues have rised:
a) When you create some licensed controls and you have them opened on the form editor if you build the application the registration form is show once by form. We tried to avoid this as we want the registration form shown only once in design time changing the line
| Code: | | If Not LicenseManager.CurrentContext Is lastDesignContext Then |
by
| Code: | | If lastDesignContext Is Nothing Then |
without success. Any hint on this? We are using third party controls that do this.
b) The license tracker always generates the same key. We think that is due to the trial restrictions but we're not sure because the docs say that two different licences can be generated and we get always the same.
c) We would like to have always different serials for different users. There is the possibility of having repeated keys generated?
Thanks in advance for your help |

Making the change you did should mean the form is only displayed once. It will mean however that the user only gets one chance to enter the key. If they don't enter the key then they would have to restart visual studio. What issues are you having?
One trap when developing design time behaivour for controls is realizing that Visual Studio will reference and load a copy of the control DLL that it then holds onto. So it is always good practice to compile your control DLL, then exit Visual Studio completely before loading the test project that references the DLL (directly not via a project reference). This ensures that the design time code you are testing (in this case licensing) is in fact the code that you think it is. If you need to debug the design time code then you can start another instance of Visual Studio and use the Debug Attach to Process option to attach to the first instance of Visual Studio which is using your control.
| Code: | | b) The license tracker always generates the same key. We think that is due to the trial restrictions but we're not sure because the docs say that two different licences can be generated and we get always the same. |
License Tracker will only generate one key (serial no) in evaluation mode. The License Key Generator can generate two separate keys (serial no 0 and 1)

The serial no is limited to a UInt16 (ie 65536 unique values). If you are fortunate enough to sell this many licenses of a single product then License Tracker will automatically wrap the serial no (ie start again). If this is a concern then you can simply change the ProductInfo that is included when you get to that point (eg set your productInfo to "W" once the serial numbers have wrapped). This will ensure that your license keys are still unique to each customer.
