Hi, I've made a minesweeper and I want to put it into windows form. I tried it but there was an error with mouseclick(): 'Mouseclick()=3' didn't work. I tried it in a simple program that just printed the mouseclick() status but the same error appeared.

I want to know whether this is just me or does anybody else have this problem. If so, is there a fix? I have searched carefully but I haven't found anything. Here's the code:



To find out what happens, press the left button, then the right, then release the left button.

Thanks.

I'm using the uninhanced version of Dark Basic. That might make a difference?

That is very strange
I'm using v1.2 and I get the same problem
It works fine without the window

I tried adding in a WAIT 40 before syncing but it didn't help
Tried adding WAIT 40 after CLS didn't help
Removed SYNC ON and SYNC, didn't help

I can't get it to work

I ran into this a while ago. Because I wanted that extra state, I had to work around the problem by combining mouseclick()=2 with with a key press .

[EDIT]
I came up with a solution - read down a few posts

Enjoy your day.

i don't have dbc, but may I suggest using different operators like
if mouseclick() > 2?
I don't know, but crazy stuff like that works for me sometimes.

Thanks for your comments guys. Unfortunately, I cannot use a susbsitute because it's a minesweeper clone and I want to make it as similar to the original windows one as I can get. I guess it's back to the full screen version for me then...

I don't remember a two-buttoned click in minesweeper?

I ripped all the minesweeper graphics for a clone but never got started, I could send you them if you like. I've even accounted for tessellation

The two buttoned click was the one where it shows whether there was a mine in the surrounding 8 squares. Made the game a lot easier. You just clicked at random didn't you

left-click on a couple of squares. Then once you've got it opened up a bit, if you click with both buttons on an uncovered space, it will either uncover the touching squares or, if there's a mine in that area, do nothing. Then you know whether you can click or not. I'm not very good at explaining this am I?


EDIT: or, apparently, typing a word right

Here's a function that'll return mouseclick 3 with 2 buttons in windowed mode.



Enjoy your day.

There isn't a problem with it on my DB and I have the new version OBese87.

Very clever Latch.

using the following code I tested your theory and interestingly enough I found that in window mode it did not return anything but values of 1 and 2 as well and the middle button did not return any value either.
perhaps this was a bug that did not get caught until recently ?





normally it works like this -
if no button is pressed mouseclick will return a value of 0
if The left mouse button if clicked will return a value of 1
if The right mouse button if clicked will return a value of 2
if The middle mouse button if clicked will return a value of 4
if there is a fourth button it will return a value of 8
IF the left AND right buttons are pressed at the same time the return value will be 3
in fact, if any two buttons are pressed at the same time it will return the added values of both

DB doesn't even read a middle click (4) in windowed mode!
Why doesn't windowed mode work properly?

@Latch:
I tried your code. It works... 30% of the time. Unfortunately your program relies on the user pressing one of the bottons just before the other, but that does not always happen (or it happens too fast for the compueter to pick it up).

I tried calling the function more often in my program. It did improve it but it didn't make much better. Here is a code snippet which shows what I am trying to explain. Notice that sometimes when you press both buttons there is a single line of one colour and then box of another, but sometimes, there is just one colour.



@OBese:
I would be very grateful to have those graphics, thank you.

Here's a routine that simply uses the Windows user32.dll to retrieve mouse input. It detects both buttons and will return a 3 when both buttons are pressed. Works 100% reliably in Windowed mode also:

I should probably learn how to use dll's

Here's the graphics >>>

I changed the big smiley button to a mine

@SFSW

I get no response at all. The value on the screen remains 0.
The function is in the user32.dll file - I don't understand why it won't work on mine. I've been looking for just that code in the win32 api too.... Any other tests I could do to see why this dll call isn't working?

@Nano

I think 1.2 has the enhancement pack, but I'm not sure if it will upgrade with the enhanced features if you didn't have it previously installed. Most likely it will. 1.2 is a pretty painless upgrade.

There's one other alternative without the enhancement pack. Do not use SET WINDOW ON. Instead, use the setup.ini file with the startup flag window=1.

In your program, use SET WINDOW TITLE and SET WINDOW LAYOUT etc.

This is for the completed exe and the ini file has to be in the same folder as the exe.

If you want to test it in script mode, set the windowmode=1 under settings.

The problem with the ini settings for windowed mode(at least on my comp) is that the window doesn't seem to be able to be moved or sized with the mouse, but the the mouse buttons work fine.

Enjoy your day.

I don't know why it wouldn't work. I just tested it on both Vista and XP, both ran it just fine. Perhaps your system is returning a different value for the call? Try <>0 perhaps, or maybe different flag values to check. It's a standard mouse input address, so it should work fine. Are you using a unique input device/mouse?

Checked the leftclick... came back -3276 something. So checking <> 0 did the trick! Thanks! That's nice.

Enjoy your day.
