FAQ: Properties
| Scaling the Barcode: Why is it not possible to scale arbitrarily to get barcodes of any size between min and max sizes? When I scale the control, the content of the control - the barcode - does not scale continuously | The control itself may be scaled to any size you need. But the content of the control - the barcode - has to be readable by a scanner. So it has to follow some rules which exactly say what size the single bars and spaces must have. This is why you can scale the barcode to any height because this does not effect the width of the bars and spaces of the barcode. But if you change the width of the control, ActiveBarcode displays the largest correct (in the meaning of not breaking the rules) barcode that is possible within the controls dimension. So you can sometimes see that if you resize the control it does not change the barcode itself. You have to resize it once again (make it wider) to change the barcode, too. Sounds confusing? If you resize the control you will understand what I am trying to say <g>.

| Human readable text line: How can I change the format of the text line under the barcode? | If you want another text line format for a barcode you can use the ShowText Property to deactive the text line under the barcode by setting it to false. Then you can create your own textline manually in the format you require with your software.
|
| Printing: How to print with ActiveBarcode? | Easy - just drag and drop the control to where you want to use and print it. For example you can drop it on a MS-Access form. With Visual Basic, you drop the barcode on your form and print the form with the barcode on it, you just need the line "Form1.Print". That is it. Please be sure that you always use the latest version since there were some minor bugs in the print routines in older versions.
You also can use the Picture property for printing. It allows you to handle barcodes as you know it from the image-object. Visual Basic developers will understand this code:
Printer.PaintPicture Barcode.Picture, 0, 0
Printer.EndDoc

| Rotating the Barcode: I would like to know if this control allows change orientation of the bar code (rotation). | Yes, starting with version 5.00 of ActiveBarcode changing the orientation is possible. Please have a look at the property "Rotate".
|
| Plain text line: Can I modify the plain text line or form it myself? | No, unfortunately, own formatting is not possible. If you liked to have another text line, you can switch off the automatic text line of ActiveBarcode ("ShowText" on "false") and then write you own text line manually under the barcode.
|
| Size: Because we translate customer numbers to barcode, it is not always possible to know the exact lenght of the code. I sometime get a Size Error. IS it possible to auto size the barcode? | An auto size option is not available now. But you have 2 possible solutions for this.
First is to always create a bigger image. ActiveBarcode always creates the largest barcode that is possible into the dimensions of the image. So create a huge bitmap for the barcode and you'll always receive a correct barcode in the best size for that image. If you create a small barcode with less numbers the barcode will be enlarged to fit best into the image size.
Second is to use the "IsSizeOk" property. You can set the barcode dimensions and then ask the property "IsSizeOk" if the barcode fits into this dimensions. If you get true, the size is good, if you get false you have to enlarge the image. Do this in steps until you get true and you have the needed size.

| Size Error: The control is displaying "Size Error". What does it mean? | This error says that the barcode cannot be displayed at this resolution. Enlarge the controls size.
|
| Text Error: The control is displaying "Text Error". What does it mean? | The "text Error" message says that the value which you would like to encode as a barcode does not fit to the selected barcode symbology. E.g. you try to encode letters in a numeric barcode such as EAN-13
Solution: Simply select a suitable barcode type (e.g. Code 128).
