4. Use C1Lc.exe to compile the licenses.licx file. The command line should look like this:

c1lc /target:MyApp.exe /complist:licenses.licx /i:C1.Win.C1FlexGrid.dll

5. Link the licenses into the project. To do this, go back to Visual Studio, right-click the project, select properties,

and go to the Linker/Command Line option. Enter the following:

/ASSEMBLYRESOURCE:Debug\MyApp.exe.licenses

6. Rebuild the executable to include the licensing information in the application.

Using licensed components with automated testing products

Automated testing products that load assemblies dynamically may cause them to display license dialogs. This is

the expected behavior since the test application typically does not contain the necessary licensing information, and

there is no easy way to add it.

This can be avoided by adding the string "C1CheckForDesignLicenseAtRuntime" to the AssemblyConfiguration

attribute of the assembly that contains or derives from ComponentOne controls. This attribute value directs the

ComponentOne controls to use design time licenses at run time.

For example:

#if AUTOMATED_TESTING

[AssemblyConfiguration("C1CheckForDesignLicenseAtRuntime")]

#endif

public class MyDerivedControl : C1LicensedControl

{

// ...

}

Note that the AssemblyConfiguration string may contain additional text before or after the given string, so the

AssemblyConfiguration attribute can be used for other purposes as well. For example:

[AssemblyConfiguration("C1CheckForDesignLicenseAtRuntime,BetaVersion")]

THIS METHOD SHOULD ONLY BE USED UNDER THE SCENARIO DESCRIBED. It requires a design

time license to be installed on the testing machine. Distributing or installing the license on other computers is a

violation of the EULA.

Common Scenarios in Mobile Applications

The following topics describe some of the licensing scenarios you may encounter when working with Mobile

components.

Updating or renewing a license

If you renew your subscription, the new license must be installed.

If the Mobile controls are licensed through a Studio subscription, then open the About Box of either an ASP.NET

control or a .NET Windows forms control and update the license by clicking the License button and entering your

serial number.

If the Mobile controls are licensed through a Studio for Mobile Devices subscription, then open the About Box of

the 1.x version of a Mobile control or run the setup again to enter your serial number. Presently, the 2.x versions of

the Mobile controls do not have the option to license or register from the About Box; therefore, it is necessary to

license through another component or the setup.

Licensing 2.x Mobile Controls through the Setup

To enter the serial number (license) through the Studio for Mobile Devices 2.0 setup, follow these steps:

1. Run the ComponentOne Studio for Mobile Devices 2.0 setup.

2. Follow the instructions in the setup, and enter the serial number when prompted.

There are cases where the setup may not prompt you. If you have a valid license installed already, or if you are

installing a version of the controls that has already been installed (Maintenance Mode), you will not be prompted

to enter your serial number. If you need to enter your serial number for an install, and the install is running in

Maintenance Mode, you will need to uninstall first. Once you uninstall, run the install again.

If you are still not prompted for a serial number by the time you get to the install screen, you must have a valid

license in the registry on your machine. If you still need to install a new serial number, remove the old license and

then run the setup again. There is a utility available that will remove the old license for you, which can be found

below.

License Remover

The license remover will search for the following licenses on your system: Studio Enterprise, Studio for Mobile

Devices, and individual Studio Mobile product licenses. Any licenses that are found will be populated into a list so

that you can select the ones that you would like to remove. To remove a Studio for Mobile Devices license with

the license remover, follow these steps:

1. Unzip and run the C1LicBomb.exe.

2. You will see an app with a list of the installed licenses on your machine. If you see both Studio Enterprise and

Studio for Mobile devices listed, select both for removal, otherwise select the one that you see. If the new serial

number that you wish to enter for Studio for Mobile Devices is not a Studio Enterprise serial number, you will

need to enter your Studio Enterprise serial number again, but this can be done through any of the About Boxes

for C1 controls with the exception of the Mobile Studio About Boxes.

3. Select any other licenses you wish to remove, then click the Remove Selected Licenses button.

4. You will be asked if you are sure that you want to delete each key; click OK when you get the dialog box.

5. There will also be a dialog box to let you know that a particular key was removed successfully; click OK for

that one also.

6. Now you can close the program and run your Studio for Mobile Devices setup again to enter your new serial

number.

Follow through with the setup, enter your serial number when prompted, and ComponentOne Studio for Mobile

Devices will be licensed on your machine.

Updating a project after renewing a license

Once you have installed a new license, each project must be updated in order to use the new control; rebuilding the

control is not sufficient. It is necessary for the control to regenerate the license embedded in its SupportInfo

property. To do this, it is necessary to force Visual Studio to update the control properties stored in the form. The

easiest way to do this is to simply modify a property. The simplest choice is to toggle a Boolean property such as

the Visible property, and then toggle it back to its original value. This results in no changes or side effects in the

control configuration, but it forces the IDE to update SupportInfo and embed the new run-time license.

Instantiating a Mobile control at run time

The Mobile controls behave the same way as other ComponentOne controls when they are created at run time and

not placed on the form at design time. Because the IDE does not have an opportunity to obtain a run-time license

on its own in this case, it is necessary to force the IDE to include a run-time license. To accomplish this, include at

least one instance of the control on a form in the assembly that is instantiated BEFORE the dynamically created

instance is created. Once a control of the same type is licensed, all others on the form are accepted as licensed.

Troubleshooting

We try very hard to make the licensing mechanism as unobtrusive as possible, but problems may occur for a number of

reasons.

Below is a description of the most common problems and their solutions.

I have a licensed version of a ComponentOne product but I still get the splash

screen when I run my project.

If this happens, there may be a problem with the licenses.licx file in the project. It may not exist, it may contain incorrect

information, or it may not be configured correctly.

First, try a full rebuild (Rebuild All from the Visual Studio Build menu). This will usually rebuild the correct licensing

resources.

If that fails follow these steps:

1. Open the affected project.

2. Select an instance of the updated component.

3. In the Visual Studio Properties window, change any property. It does not matter which property you change;

you can change it back to the previous value.

4. Rebuild the project using the Rebuild All option (not just Rebuild) and run the solution.

Alternative 1: Follow these steps:

1. Open a new Visual Studio.NET project.

2. Add the updated component to the form.

3. Compile and run the new project.

4. Open the licenses.licx file in the new project.

5. Copy the line that starts with the namespace of the updated component (for example, C1.Win.C1Report)

and ends with a public key token.

6. Open the existing, incorrectly licensed project.

7. Open the licenses.licx file in the new project.

8. Paste the line from step 5 into this file (replace the old licensing information with the new).

9. Rebuild the project using the Rebuild All option (not just Rebuild) and run the solution.

Alternative 2: Follow these steps:

1. Open the affected project.

2. Delete the licenses.licx file from the project.

3. Add a new instance of the updated component to the form.

4. Rebuild and run the solution. The nag screen should not appear.

5. Remove the newly added component from the form.

Try each of these options multiple times, if necessary. If that still does not help, are you creating any of the controls in

code rather than design-time? If so, you must add an entry for the control in the licenses.licx file (see

http://helpcentral.componentone.com/PrintableView.aspx?ID=1886 for more information). Also if this is a website, as

opposed to an ASP.NET web application, please try right-clicking the licenses.licx file and selecting "Build Runtime

Licenses" from the context menu.

I have a licensed version of a ComponentOne product on my web server but the

components still behave as unlicensed.

There is no need to install any licenses on machines used as servers and not used for development.

The components must be licensed on the development machine, therefore the licensing information will be saved

into the executable (.exe or .dll) when the project is built. After that, the application can be deployed on any

machine, including web servers.

For ASP.NET 2.x applications, be sure that the App_Licenses.dll assembly created during development of the

application is deployed to the bin application bin directory on the web server.

If your ASP.NET application uses WinForms user controls with constituent licensed controls, the runtime license

is embedded in the WinForms user control assembly. In this case, you must be sure to rebuild and update the user

control whenever the licensed embedded controls are updated.

I downloaded a new build of a component that I have purchased, and now I'm getting

the splash screen when I build my projects.

Make sure that the serial number is still valid. If you licensed the component over a year ago, your subscription

may have expired. In this case, you have two options:

Option 1 - Renew your subscription to get a new serial number.

If you choose this option, you will receive a new serial number that you can use to license the new components

(from the installation utility or directly from the About Box).

The new subscription will entitle you to a full year of upgrades and to download the latest maintenance builds

directly from http://prerelease.componentone.com/.

Option 2 – Continue to use the components you have.

Subscriptions expire, products do not. You can continue to use the components you received or downloaded while

your subscription was valid.
