For my login control I'm using parameters in an SQL statement. Trouble is if people use SQLinjection, I'm afraid they'll be able to get in too. I have two textboxes and the values are passed on to an SQL statement, this checks whether the values are found in the DB.
Is there a way to make sure this isn't possible? I know in PHP you need to use something infront of the textboxes.
I want to display an equation prior to solving it. Obviously in MS word etc I can use equation editor to write an equation, but I'm writing my own program.
Is there an easy way to display an equation. Obviously I could use text to write eg as text "a=b^2-3(c-d)/5" and everyone here would have little problem interpretting what I want but I want this to be accessible to 12 year old children.
Alternatively I could try and manipulate lots of text boxes one on top of the other to try and explain what I'm doing
The third alternative I thought of was to write in equation editor export the graphic and then import a graphic.
I'm sure I must be trying to reinvent the wheel - which I believe is the one thing OE programming is supposed to avoid.
Embedding exe's in a form, into a Panel, for example, is fine, for such apps as notepad.exe, calc.exe, etc, but NOT for cmd.exe which throws an exception, because it is not a UI. This code demonstrates: Form with one button and one panel:

Well, i was thinking of making a Tetravex solving program in order to practice my code writing skills (language will propably be Visual Basic) and I need help finding an algorithm for solving it. For those that don't know what tetravex is see this http:[url]... . The only algorithm I can come up with is the brute force way, place a tile randomly in one corner and try every possible tile next to it and continue the same process, if it reaches a dead end revert to a previous state and place a different tile.
