View 2 RepliesI have made updates to my programs, including a large update with the fonts on my forms. The only problem is this font is not found on vista or Windows XP and must be downloaded. The program is completely ruined with its looks without it. Is their a way so that both Windows XP and Vista could download these fonts, On startup of the first form, Form Load maybe? Even if the user says that he or she would like to see the program with the fonts? I just don't want to take the many hours i wasted resizing with the new fonts, ect. If it would be easier I could ask the user if they are using Windows XP, Or Vista?

From what I've been reading, APIs seem like the way to go. But, if I can, I'd like to keep it to managed code.
I've checked with the manufacturers to see if they had any available APIs that could allow me to do the automation, but they have none
What do you all think is the best approach? Is there any .NET methods to assist me? Or do I have to go with APIs and unmanaged code?

View 2 RepliesI have a multi user app that works over a WAN and prints 2 types of documents:
1. Bus Tickets
2. Reports
Generally all users will have 2 printers connected to their PC (A Dot MAtrix printer for the continous paper tickets)and an inkjet or laser jet for reports.
How do I send certain print jobs i.e. Tickets automatically to the dot matrix printer and other print jobs automatically to the other printer?At the moment the dot matrix printer is set as the default printer on all machines, the reporting printer is then selected by the user whenever he/she wishes to print a report.This is not ideal however since most users run other apps on their machines and would prefer the plain paper printer to be set as the default.
I would like to obtain the device names from a database table or file on the user's machine so that the following occurs:
1. When A ticket is to be printed the printer object is automatically set to that of the dot matrix printer without offering an option.
2. When a report is to be printed the user is offered a dialog box(I know how to do this) WITH THE PRINTER NAME OF THE REPORT PRINTER APPEARING AS THE FIRST CHOICE.
1. How do I obtain a list of printers that are available on each computer?
2. How Do I set the printer object depending upon the job that is to be printed?
This is a simple program, nothing crazy, just for a VB class. The program just a food ordering form. Each part of the order has a group box, with the type of sandwich, side, beverage, dessert you want selected via a combobox, and toppings selected with checkboxes (the code for the beverages is coded differently and giving me 0 problems, but at the instruction of the teacher who saw beverages giving conflicts with the way everything else was coded because radio buttons are used instead of checks).

How can I delselect in a treeview and then cause an event to trigger when nothing is selected.
I can deselect when I left click any of the white space adjacent to any branches but not below them if that makes sense, is there any way for it to work when you are not adjacent to any nodes? I am using this code to deselect.
