VB6 codes sending Function Keys to my online games

[joi]

Hello friends ! I'm just a newbie and not good in programming. I have couple of questions that i want to ask regarding to my codes that i used in my application.
The application i made is an auto key presser. These codes are working fine in my favorite online game but not perfect.

vbKeyNumbers, vbkeyAlphabet, vbkeyReturn, vbKeyESC and other keys are working in my online game. Except Function Keys(F1 to F12).

But in notepad. Function Keys are working perfectly.

Here's the codes i used.

Here's my questions.

Can you give me an advice what strategy or what codes should i use or add to my Auto Key Presser to make the Function keys works in my online game?
Sending Function Keys(F1 to F12) to an online game window. Is it possible in Visual Basic 6?

[Gill Bates]

I am having a hard time understanding what your specific problem is.
What happens when you try to use them in-game? What do you mean they are working fine, but not perfect?
Be more thorough.

[joi]

The questions is in my post. 1. "Except Function Keys(F1 to F12)". 2. "Can you give me an advice what strategy or what codes should i use or add to my Auto Key Presser to make the Function keys works in my online game?". 3. "Sending Function Keys(F1 to F12) to an online game window. Is it possible in Visual Basic 6? ".

Using my Auto Key Presser. I can use the auto skill attack(Using Number keys) and Auto Pots(Using Alphabet keys) in my online game.
But i cant use the Function Keys (F1 ~ F12) even though in note pad. Function keys are working. But In my game. It wont works. The function keys are used to switch between first set of skills to the next set of skills in my online game.

They might not be working because those keys are already being used for other functions by the actual game.
Try to use different keys..

[joi]

But Only the function keys are able to switch the set of skills to another.

Do you have any idea how will i use function keys to my online games?

[Filous]

how do you have vb6 if you're a newbie?
i'm hella confused. i tried to find it years ago but was unable.

[joi]

I mean... I am new in this site.

What do you mean "i tried to find it years ago"? Codes for auto key press? You can use my codes i posted in my 1st post.
But i don't know if the vbKeyF1 to vbKeyF12 will works to your game.
