The Custom Resource Locator sample demonstrates a custom implementation of the resource locator to load pictures from the user's Pictures or My Pictures directory. In general, you can use a resource locator in a report to find any resources that a report may require.

Details
When you run this sample, you see the MainForm with the list of images from the Pictures or My Pictures directory. Select any image and click the Show Report button. A report with the selected image opens in the PreviewForm.
Caution: To run this sample properly, you must have image files in your pictures directory. If the directory does not contain any pictures, you should add them to the folder manually.
The sample consists of:
- Resources folder: This folder contains the Description.rtf file that contains a summarized content of the resource locator that gets displayed inside the RichTextBox control on the MainForm at run time. This folder also contains the NoImage.bmp image file that is used if there is no image in the pictures directory.
- DemoReport.rdlx: The DemoReport.rdlx displays the selected image. This report contains two TextBox controls and one Image control, which display the image name, the image type and the image at run time after you click the Show Report button on the MainForm.
- MainForm: This is the main form of this sample that appears when you run the sample. This form contains the RichTextBox, the ListView and the Button controls. The RichTextBox control displays the summarized information saved in the Description.rtf file about the resource locator and the sample. The ListView control gets populated with the images located in the My Pictures directory; the Button control is used to generate the report with the selected image. Right-click the form and select View Code to see how to load text in the RichTextBox control and images in the ListView control. It also contains code that displays the DemoReport.rdlx on the showReport_Click event.
- MyPicturesLocator: This file is an internal class that contains code that looks for resources in the My Pictures directory.
- PreviewForm: This form uses the ActiveReports Viewer control to display the DemoReport.rdlx with the selected image. Right-click the form and select View Code to see how to load the report into the Viewer.
