Simpol Limited

Now that the data is in SIMPOL format, we can convert the form. The form conversion tool is a Superbase program. To successfully convert a form, it is necessary that opening the form can successfully open all the tables that the form requires. From the Start menu, select SIMPOL Professional+Utilities → SBV to SIMPOL Form. The program will run and ask you to select a form. Select the form you wish to convert. It will be opened and the program will ask you to enter a file name for the output file. After that it will convert it and ask if there are any more to do.

In this example, we will be converting the CHECKIN.SBV. The original is shown below.

The following image is of the converted form, without any modifications done to it, merely opened as is in SIMPOL Personal™.

As we can see from the converted form, it looks different in a number of ways. That is in part because the controls on a Superbase form are not native controls. Instead they are all drawn by Superbase. Also, the original form was not sized correctly, it is actually much longer than it needs to be. Also, in Superbase the background of a label could be optionally turned off. This is not an option with real Windows controls. The rest are relatively minor adjustments. One thing that the conversion program does not yet do, is transfer the tab order. That is because tab order works quite differently between the two. Eventually this may also be added to the converter. That was hand adjusted as part of the work in the Form Designer.

Another thing that is different is the Superbase text boxes in the original form that have no border, and are not recessed. This option is not available in standard Windows controls. SIMPOL has its own trick here though: dataform1text controls are data-aware (can be bound to a field), labels in Superbase are not. Also note that the buttons are using a different color scheme to the rest. That is because they were defined as using the standard color scheme. In Superbase the colors are fixed. In SIMPOL, they can be tied to the current theme.

Another problem is the missing image. The reason it is missing is that the image was pasted into the form from the clipboard, and there is no way to extract the image from the form programmatically. In fact, the only way to do it is to capture it off the form.

By opening the form in SIMPOL Personal™ and modifying it in the SIMPOL Form Designer, the resulting form looks like this. This is being shown in SIMPOL Personal™.

As we can see, it now looks very much like the original. In some ways, it looks better. It now uses the system theme for the vast majority of colors (not all, however, since some text was blue, and it is not supported to have the text color using system colors and the background color using fixed colors). The information in the Flight No. section of the form that is in blue is actually looked up from the FLIGHT table using the FlightNo as the link.
