|Dynamic Image plug-in to your own application: display images from a folder, not a database. cViewIMAGEPro provides royalty-free runtime so you can embed it into your application and distribute it freely to make reports sharper and more useful. Free 30-day trial. |
Add depth and clarity to your Crystal Reports, by including images dynamically. A properly designed report can use dynamic image inclusoin such that the image displayed depends on the data and the formulas that manipulate the data. This can take your reporting system to a whole new level.
Why cViewIMAGE Pro ?
|The Pro version of cViewIMAGE provides royalty-free runtime so you can embed it into your application and distribute it freely. |
Why dynamically include an image in a report? Images are very compelling and give a report great eye appeal. You can use them to convey information in ways that text alone cannot. You probably already guessed we would say it: A picture's worth 1,000 words.
Why use cViewIMAGE to do it? cViewIMAGE offers functionality not available by other means (see the cViewIMAGE v. Crystal XI tab).
cViewIMAGE is one of our best-selling products. Once you start using it, you'll understand why.
How it works
|cViewIMAGE allows a developer to design a report that calls images for dynamic inclusion. To see those images, the clients must also have cViewIMAGE installed. cViewIMAGE enables you to include images in your Crystal report even if they aren't stored in a database. |
Hold the reference to the image e.g., c:\Product Images in your database, instead of the image, and cViewIMAGE will retrieve those images from the folder for your Crystal report.
You do not need the image to be stored in your database. Your database simply holds the file path to the image, not the image itself.
The advantages are that:
How would you use cViewIMAGE to do it?
To put your image of say, your product into your Crystal report, you would create a new connection using cViewIMAGE as well as your normal Product database/file connection. Then write a formula to access the file path reference of the image (e.g. c:\Product Images) from your Product database to point cViewIMAGE to the folder/s where your images are filed.
Then place the image in your report along with any other information from your Product database.
vs. Crystal XI
|While XI does support dynamic images using its own mechanism, it still supports cViewIMAGE. The ImageFolder driver in cViewIMAGE brings in all the pictures from a folder--something XI can't do. cViewIMAGE does have functionality which is still not available in Crystal in this form and as far as we are aware, is not planned to be in later versions of Crystal. |
So there are still benefits in using cViewIMAGE even if you have Crystal XI or Crystal 2008, depending on what you are trying to do.
By using different arguments, you can pick up different cViewIMAGE COM drivers which provide different functionality.
Functionality available only in cViewIMAGE as far as we are aware:
The functionality now available in Crystal XI that is similar to other cViewIMAGE COM drivers: cViewIMAGE.WebImage (from cViewIMAGE version 4) and cViewIMAGE.SingleImage (often used)
|cViewIMAGE supports only the Crystal-supported formats. For example, it supports jpg, bmp, and WMF but not GIFF. |
Although Portable Document Format (PDF) is popular, it’s not an image format. It is exactly what the name says: a way to preserve formatting of a document for portability..
Here are some tips to solve common problems when installing or using cViewIMAGE:
1. Elevated Administrator: On your Windows 7 machines and later Operating systems, please register the cViewIMAGE.dll file using Elevated Administrator (Command line utility / Right click / Run as Administrator). This is because even the normal Administrator user on that operating system and later does not have the full set of rights but needs the elevated rights.
2. The COM datasource: When creating a formula, the COM datasource that cViewIMAGE uses is listed under Datasources or More datasources in the Crystal Formula Editor. If you cannot see COM listed, either re-install Crystal and tick the box that asks if you want the COM option or else copy the driver from our Drivers file. Which driver you use eg crdb.com.dll depends on your operating system and version of Crystal.
3. Folder location for driver: The COM data driver eg crdb.com.dll or P2smon.dll needs to be placed in different folders depending on whether you have 64 bit or 32 bit and also what version of Crystal you have.
4. Appropriate location: Files such as the license file or the driver etc which needs to be placed in the folder appropriate for your Operating system or version of Crystal eg:
5. Location of Images: If they are local on your development machine, there will also need to be a copy local on your user machines.
6. Network permissions: To troubleshoot when your images are on a network folder, please move the images temporarily to a local drive eg c:\, If that solves the problem, we know it is a network issue - probably related to the user not having sufficient permissions for cViewIMAGE to access the network folder. (This will involve changing the formula which builds up the path so cViewIMAGE can find the images on your local drive)
7. Deploy on another machine: If you want to deploy cViewIMAGE on another machine you will need to install and register cViewIMAGE.dll on each machine. These files can be in any local folder on your machine.
8. License file: Each machine running cViewIMAGE will need the “license.xml” license file you received when you purchased cViewIMAGE for that machine.
9. Register: cViewIMAGE needs to be registered on each machine that uses it eg depending on your operating system RegSvr32 "c:\Program Files\cViewIMAGE\cViewIMAGE.dll"
10. Speed. If the images are on a network drive, the report will run a lot slower. Remember also that the user must have permission to access the folder of images.
12. Disc space: As cViewIMAGE is trying to move the images to the local machine for processing, check whether disc space on individual machines might be too small.
13. Use a backslash: When building up the file location in your formula, remember to use a backslash eg c:\Projects\cViewImage\Demo v12\bette.bmp
14. Quote marks: We have found that sometimes the formula building up the path contains quote marks not recognisable to Crystal, eg ones copied from Word or Outlook. Replace them with the double quote mark from the keyboard.
15. File extension: Remember that the formula needs the file extension for the image eg .jpg or .bmp or .wmf or .png. Crystal does not support .giff and cViewIMAGE does not support .pdf. The extension needs to be included when building up the file path location in the formula used to point to the location.
16. Conflicting dlls: There is a utility called Modules which may help your IT department to identify conflicts with dlls. You can search for & download this free utility from the Internet.
17. Bar codes and fonts: Check whether there any barcode or other fonts that are installed on the working workstations but not on workstations that are having problems.
