How to make a simple Event

Hello,

I'm programming a program that opens a second window and directly prints it. I thought I could use the event Form_Load. But if i print the form at that stage it will become totaly black (I think because the form has not finished loading yet). So I need a trigger to print the page directly after it is loaded, and this trigger can not be user input.

Who can help me on calling my print function when the page is loaded?
Thanks,
pieterjann

How about the form loaded event?

pieterjann 6-Aug-12 10:27am

is there a form Load AND a form Loaded event? if so could you give me an example of the form Loaded? My printing function makes an image of the form and prints that. As the form is not completely loaded at the form Load event it returns a black page....

Give you an example? Go through the events list in the designer and select it from the list.

Could you call your Print function from the form that owns the one you want to print?

Otherwise I think you might need to overide OnPaint.

Makes no much sense to speculate before OP creates some code sample and show how to reproduce the problem. And I voted 1 for "Solution 1", which is pure evil.

Your question is "who"? Not quite a valid one... :-)

The approach to the problem is simple: you should write a code sample, as simple and short as possible, to reproduce the problem. Then, if you still would not come to a solution, post it with your question, using "Improve question". By the way, "Load" is a "fake" event, it simply invoked right after a constructor is called, so using it cannot solve any problems; with equal success, you can call some method from your constructor, at the very end.

Solution 1

Final answer:
Add a timer and disable it after the tic.

It might work but it stinks.

This will work only if the form loads before the timer ticks which is not guaranteed - a poor solution in my opinion.
There are several events raised by the form itself that may suffice (such as Shown) that would be more appropriate.

Sergey Alexandrovich Kryukov 6-Aug-12 12:08pm

Very, very bad idea. It does not solve anything; and it totally pointless. Using timers is generally bad, but here it does not have any reason at all. And if it apparently "solves" the problem, it could be even worse: the original problem is hidden, the reasons are not understood, and you would just close the way to understand it -- very nice. You got very deserved 1, but this is not a main thing here. I would like to help you with the advice: your approaches to solving the problems will get you into trouble. Don't do such things.

Ok so you say do not do this. I tried with the event Shown, but it is not activated :( I will search a bit more before I ask you guys to solve my problem :)
