The SpawnDialog and SpawnWaitDialog events do not replace the previous page, but launch a new subordinate dialog box. The first waits for the user interaction to be rejected, but the second becomes visible only until the conditional expression remains false. In our case, it is a waiting dialog box that is only visible while the installation program calculates the needs of the disk. For a small installation package like our example, it doesn`t take long, so you probably don`t have a chance to see this dialogue in action. But let`s only have him there just in case. CostingComplete is a predefined property that is set at 1 when disk need calculations are completed. Finally, the well-known nuisance: the Next button remains disabled until the user has given consent to the license agreement. We`ve already used condition tags at the higher level (start-up conditions to determine if the full installation process should be run) or in feature tags (to disable the installation of different features under certain conditions). This is their third use, in control tags. The Action attribute allows you to disable, activate, hide or reset the control element or reset it in the default state if the condition in the tag is considered true: stackoverflow.com/questions/16978501/how-to-create-a-bootstrapper-application-without-a-license-agreement-step you can also specify the text of the contract in the source file, but the previous solution seems much easier to manage: the first reference contains the corresponding UI library, but it does not automatically use localized error and action files (or modified, in the case of English) in the text of the language. Without the second reference, the installation package becomes a little smaller and uses the stock messages in the Windows installer. To view the optional text on the ExitDlg document, set the property WIXUI_EXITDIALOGOPTIONALTEXT on the channel to be displayed.
Example: There is a well-known problem with the rich text control that is used to display the text of the license file, which can lead to displaying the empty text until the user scrolls down into the control. This is usually caused by complex RTF content (z.B the RTF generated when recording an RTF file in Microsoft Word). When you run this behavior in your configuration user interface, one of the following bypasses is corrected in most cases: this is where it gets ugly. We can easily replace the default license by changing the WixLicenseRtf WiX variable as follows: where the license is the name.rtf of your EULA license file. The downside of this method is that you can only have a license file, which means there is no location for them. That`s why we have to find a way around the problems. The license is verified for a LicenseAgreement dialog box name. What we need to do is replace this dialog box and insert the location feature. Then there is the text of the license agreement. We open a text wrapped with content to scroll through.
The text itself enters the day of the inner text. The best idea is to create your license agreement in a word processing program and export it to RTF (Wordpad is probably the best word processor for this purpose, more sophisticated could create much more detailed RTF files; even if you use it, you should back up the final version of Wordpad again): look at the control element with “Id LicenseText” and read the comments. We have the text source of the original license in “a (var. ProjectDir) ” (loc. LicenseRtf).” The Var. ProjectDir is the directory of the project file. That`s right! (loc. LicenseRtf) is where all magic text, which is displayed in built-in WixUI dialog boxes, can be replaced by custom channels on demand.
To do this, you need to add a string that has the same ID value as the chain you want to crush to your product`s WiX (.wxl) location file.
