Xojo printersetup5/25/2023 ![]() Than use QuickList.AddValue to add a value as often as you need. You can pass of course a text with initial list items. To build a list, you also call QuickList.New. When done, please free the list from memory using QuickList.Free function. You will notice that for a lot of entries, the plugin will be magnitudes faster. The function QuickList.GetValue now reads a value and if you do a loop over thousands of entries. You query the number of items using QuickList.Count function. The plugin will parse it once for fast access. With QuickList.New function you create a new list passing the text of existing list. The MBS Plugin now offers QuickList functions. The longer the text is, the longer this search will take. Each time you query a value, the FileMaker runtime has to loop over the content of the text and find the nth item. For accessing list in a loop, you call GetValue a lot. The longer the list becomes, the longer the copy process will take. Appending list entries requires FileMaker to make a new text and allocate memory for new size, copy existing text and new text together into the new text and return it. If you start to process lists with 10000 or more items, you will see degrading performance. To query a list you can use ValueCount and GetValue functions. You can build them easily in FileMaker calculations by appending new text to a list and using the ¶ character. Those lists are simply text separated with new line characters. PPS: The WindowsDeviceModeMBS class in MBS Win Plugin can help to convert from ANSI to Unicode and back if needed.Quicklist - Fast lists for FileMaker In FileMaker you use value lists for various things. PS: If SetupString odes not start with "DoNotAlterThis=SetupString.2" or you are not on TargetWindows, you should not touch it as that may be a new future format. Implementing the proper function to test a setup string is left as homework to the reader. Skipping two bytes the next two bytes should be &hDC &h00 for Xojo 2017r2 and &h9C &h00 for Xojo 2016r3. But if you find it, you look in the binary data, if you find the bytes &h01 and &h04 exactly 32 or 64 bytes after the start of the binary data. from a new PrinterSetup object and you can simply use it. If you don’t have it, this is an incomplete setup string, e.g. To detect the format of a setup string, you can do the following: You find the string DevModeStructurePS= in the setup string. If you sum it up, you get &h054C and &h50C, which are exactly the sizes above. The next number is the driver’s data size in bytes, e.g. This value can be &h00DC for size of DEVMODEW structure for Xojo 2017r2 and &h009C for size of DEVMODEA structure for Xojo 2016r3. The following field is the size of the structure, not including any private, driver-specified data. Followed is the spec version &h0401 for Windows 2000 and newer. In the byte stream you see first 32 characters in both versions, either unicode (64 bytes!) or ANSI text. Please note the format can be printer specific and change depending on which fields are checked in the printer dialog! ![]() Values are for example 1292 for older format and 1356 for newer format of the same printer. One of the values listed is DevModeStructureSizePS which shows the size of the binary data. While the exact format of SetupString is not published, you can see it’s text with an embedded binary part. Sadly Xojo missed to increment the version number in their string to ignore older setup strings automatically! You run into problems if you use an older SetupString with newer Xojo versions. Xojo 2016r4 and newer use the unicode version. Xojo 2016r3 and older use DEVMODE structure to describe the printer setup in the ANSI version. Detect PrinterSetup data format As you may know Xojo 2016r4 to 2017r2 made a move to use DirectDraw for printing.
