You have to open a Visual Studio command prompt, then type ILDASM to launch the IL Disassembler. Open the compiled .EXE or .DLL in that and you can see all the IL code.

Like the others said, use Reflector or ILDASM. This link to opcodes/instructions [^] can be helpful for you, as well.

Have you checked your CheckCollision method?? What is BallX(MyBall) = 1 supposed to do??

first of all thank you very much sir
sir i am new and i am doing my assignment and i am haveing problem with this since last 4 days i have debug program somany times but i could not find any thing so can you please kindly help me with this
i put ballx(myball)=1 because there is only one ball that's why but i am not sure can you please tell me what do i need to do
waiting for your kind rep.
have a nice time

OK. So you set a variable to the number of balls on the field when a collision is detected. Do you see something wrong with that?? What do you WANT it to do when a collision is detected?? YOU have to write the code for that. I can't tell you what to do with it because I have no idea what you want it to do.
Homework assignments are tricky for us because if we just gave you the answers, you wouldn't learn anything you needed for the next class.

thanks again sir
i have made few changes so please have a look
and when ball collid with padle i just want ball to bounce back randomly i think it's working
but now next problem is when i dilebaratly miss ball it's still make sound and that's i doint want, but it's suppose to not make any beep sound but i think it's passes through the padle line, but i dont know that am i right or wrong ?
any help for this
the new code is
If BallX(I) < (MyBat1.Width) Then<br />
BallDirX(I) = 1<br />
Collided = True<br />
Beep()<br />
End If<br />
<br />
Public Sub CheckCollision()<br />
Dim Collid As Rectangle, Collided As Boolean<br />
Collid = Collid.Intersect(MyBat1, BallRct(MyBall))<br />
If Not (Collid.IsEmpty) Then<br />
BallDirX(MyBall) = -BallDirX(MyBall)<br />
<br />
End If<br />
<br />
End Sub
and as you said that if you give me answer i want learn that's very true but i just want right direction sir
waiting for your kind rep.

I can't find double click on combo box.. i only have mouse double click event.. but it doesn't work.. is there any switch, something in the properties that i need to set?.. Pls Help, and thanks in advance..
|
|
|
|
|
The ComboBox doesn't expose a double-click event. Frankly, it's not inuitive to double-click on anything in a ComboBox, so why would you need it?
|
|
|
|
|
Thanks for replying..
My situation goes this way... my combobox holds the list of my contacts.. and if i want to view / edit Personal Information of that specific contact.. i'll just double click the combo box to show my contacts information form... In that way i can go to my contacts info by just double clicking my combox...
|
|
|
|
|
Hi!,
I am not trying to ask you to change the design of your app., but a feasible solution is an Edit button right besides the cboBox so that the user may select the comboBox item and then click on edit to edit the selected record.
This way the user is not forced to do any extra thing, since any which way he had to click TWICE to edit/view the record.
Hope this helps you out in some way or the other.
Happy Programming!!!!

Your right, but the company stantard is use to that.. hehehe... I just adapt it to my next project.. thank for sharing...
|
|
|
|

Make it any way you wish. The ComboBox still doesn't expose a double-click event.
ListBox and ListView, more traditionally used for what you describe, both expose a double-click.

Hi All,
In VB6's, Combobox has MatchWithList...
My problem is, i cant find the counterpart or equivalent of MatchWithList in VB 2005's Combo Box..
Does anybody knows where can i find it?
Please help and thanks in advance....

You're looking for the AutoCompleteMode and AutoCompleteSource properties.
|
|
|
|
|
Thanks alot is working...
Is there any property that will let me know if that AutoCompleteSource will nothing so suggest..? something like giving "true" if it suggested a string or "false" if it no suggested string?
|
|
|
|
|
Nope. You'd have to make your own version of the ComboBox to do that. Probably tracking how many characters the user actually typed against the length of the string in the Text property, maybe.
|
|
|
|
|
public static bool MatchWithList(ref ComboBox cmb, string cmbText)
{
bool matchexists = false;
int i = cmb.FindStringExact(cmbText);
if (i != -1)
{
cmb.SelectedIndex = i;
matchexists = true;
}
else
{
matchexists = false;
}
return matchexists;
}

Yeah....ok.  And why are you replying to a 4 year old message??

Is it possible to sort a record in crystal report using Formula Fields? Example: I want to sort my List of Depositors base on there Balance... Wherein Balance = Sum({Deposit} - Sum{Withdrawal}... ?

Create a new Group based on the formula.
