Frequently asked questions on Clic 3.0

ClicDB does not print reports

    There is compatibility problem between Windows 98, NT and 2000 with applications made with VisualBasic 3.0 (like ClicDB) and some HP printers when the screen is configured to more than 256 colours. The problem is explained in Microsoft support pages.

    Solution: Configure the screen to 256 colours before printing, using the "Screen" icon in the Control panel of Windows. When done, return to the original resolution of 16 million colours.

I can't install the activity packs found in the Clic corner!
    This problem can be due to one of the following reasons:

    a) "Corrupt installation media" message appears
    It means the installation file has become corrupt during the downloading process. The only solution is to delete the bad file and download it again.

    The installer files larger than 1.4 MB are divided into separated pieces for easier copy to diskettes. The first portion always contains the EXE extension and the rest have the same name but with ending with W02, W03.etc. The normal process is to copy all the files into a single folder in the hard disk and then run the first file, which will access the information contained in the others when necessary. You can also copy each file into a separate disk, run the first one and the change them when the installer program asks for it.
    The problem can appear when the files are downloaded using Internet Explorer 5.0, since in some cases the file can be saved with the name changed. For example, it could happen that when downloading the file COSHUMA.W02 it gets saved in your computer with the name COSHUMA.W02 (with two dots) or COSHUMA.W02.W02 (The extension is repeated). Solution: manually rename the file so that it has its original name (in this case COSHUMA.W02).

    c) The installer says I have an old version of Clic already installed
    The installers base their operations on the information found on the section [Extensions] of the file win.ini. The win.ini file is updated while the installation of Clic, but this information stops being valid if we move or rename the Clic folder. For example, if you have dragged the Clic folder to "Program Files" probably you will find this error message. Solution: repeat the installation of Clic 3.0 indicating the folder where you really want to place the program.

How can I modify Clic activity packs?
    Clic activity packs can be presented in two different formats: "open" packs (have the PAC extension) and "compacted" packs (have the PCC extension). The activity packs in open format can be modified directly from inside Clic through the menu Edit - Edit activity, but the compacted packs are protected and the modification can't be done directly.

    The majority of the activity packs found in the Clic corner are distributed in compacted format (PCC), but can be converted into open format (PAC) through the utility ClicPac, that can be installed with Clic.

    The steps to follow to modify a PCC are:

    1. Convert the PCC into a PAC through ClicPac.
    2. Run Clic and, in the File-Open menu, search for the PAC file.
    3. Modify the activities as desired.
    4. Reconvert the PAC into a PCC to protect it.

    You will find more information in ClicPac's help and in Clic's user's manual.

How do you prepare the EXE installer files for Clic activities?
    The installers can easily be created with the MKInst utility.

    Juan José Mateo Molina has found a shareware version of WISE (2.0), which you can use to make more customized installers. You can find this utility and the instructions in his páginas de aplicaciones educativas (in Spanish).

Some of the buttons in Clic 3.0 appear with a wrong image
    This error can appear sporadically with some ATI video cards. The manufacturer recognizes that it's latest versions of the drivers for Windows 95/99 are not 100% compatible with 16 bit applications (and Clic is one of them!). As a consequence the manufacturer proposes the installation of the version 5.11 (build 4.10.2330), which after the trials we have managed to make, behaves well with Clic.

    In ATI's web the reasons for this problem are explained, and the version 5.11 of the drivers can be downloaded.

Clicking on the "Fonts" button makes the program freeze
    This occurs when there is an exaggerated amount of font types installed in the computer (more than 1000). Clic tries to prepare a list with al the names and runs out of memory. The solution is simple: take out of the folder Windows\Fonts the types that aren't used regularly and copy them into a different place in case they become necessary in the future. You'll see the applications running a lot quicker and smoother.

    Warning: when doing this clean-up of fonts you should never touch the system fonts (Arial, Times New Roman, Courier New, System...) nor the font Marlett, which is the one used by Windows to draw the buttons that appear on the corner of the windows. A good way of doing this is to only move those fonts that have an installation date posterior to the installation of Windows.

I have a sound card but it shows an error every time I play a WAV file from one of Clic activities
    The WAV files inside Clic activities are compressed using the audio MSADPCM. The Clic installer adds this codec when it is run from a Windows 3.x, but it won't do it for Windows 95 since it is supposed to be already incorporated by default. If the W95 installation was incomplete it could be that the codec wasn't installed. To correct this problem, follow these steps:

    1. Open the W95 Control Panel.
    2. Double clic on the icon Add/Remove Programs.
    3. Choose the Windows Installation icon.
    4. Double clic on Multimedia.
    5. Check the Audio Compression box, the program will ask for the Windows 95 installation CD to add the codecs.

Can we avoid error messages from showing up when we are running a multimedia activity?
    In computers that don't have sound cards you can deactivate the use of the multimedia files modifying the file CLIC.INI, which is found in the Clic directory. With Windows Notepad you need to change the lines sound, midi, wave and mci to say "=no". The modifications will become active the next time you run the program.

    The versions 2.2 and later detects if the computer has an installed sound card and, in case it doesn't, it disables the reproduction of the multimedia files.

The screen shows up with a transparent background!

    It is due to the presence of an old version of BWCC.DLL. The solution: copy the file C:\CLIC\BWCC.DLL to the directory C:\WINDOWS\SYSTEM.

We've created some images with "Paint Shop Pro" but Clic tells us the format is not the right one

    Surely you have saved the images in BMP format, a "Windows RLE encoded" sub-format, and the only sub-format recognized by Clic is "Windows RGB encoded". Anyway, it is always better if you save your images in GIF format.

We've created a drawing with "Paint Brush" but Clic shows it too small and in a corner
    When you create a new image PaintBrush prepares a surface of 640x480 pixels. Even though your drawing may occupy only a small portion of the surface, PaintBrush will save the entire image. The solution is to save only the portion of the drawing that you are interested in:

  • If you work with Windows 95 "Paint" you can adjust the image size by dragging the lower right hand corner to the desired size.

  • In Windows 3.1 you can use the rectangle tool in PaintBrush to select the valid zone in your drawing and then use the menu option Edit - Copy to... to save only the selected area. On exiting PaintBrush say NO; you don't want to save the entire drawing (It's enough with the portion you have selected and saved previously).

The images appear with different colors!
    This problem occurs when you use many images which are 256 colors from different palettes. For example, if in the same activity there is an image with 256 grays and another with 256 tones of blue. you would need to simultaneously show 512 colors. If Windows is set up to millions of colors there won't be a problem, but if it is configured to 256 it's impossible to have 512 colors on the screen. Some programs solve this problem by drawing patterns instead of pure colors, but Clic doesn't have this option. The result: the grays will look bluish or the blues grayish, depending on which image is last therefore imposing it's palette.

    The solution: save all the images with a common palette. This can be done from within PainShopPro, increasing the color depth (menu Color - Increase color depth - 16 million colors) and then lowering it again (Color - Decrease color depth - 256 colors) choosing in this second step the option Palette Standard and Error diffusion.

    Another possibility that offers better results is to use the program Jasc Batch Master, that you can find in our page of resources, for calculating and applying the optimal palette for all the images. The function to choose is Apply fully optimized palette. It is recommendable to always select the box Include Windows Colors.
