Unfortunately dave..I can't cheese yet.Code which u gave to me is to make bitwise shift, not for bitwise rotation.So..I'm back to you,how can it be done?Maybe,I give a simple example what I mean about bitwise rotation.
Ex:
value : 1110001111000111
rotate : 5 bits
result : 0111100011111100
But anyway thanks again, u want reply my question.It means to me..

After a little research and testing, there is also a problem I forgot about. In VB6, the shifting doesn't work in all cases because VB works only with signed numbers. If you use the techniques on &hFFFFFFFF (-1 decimal) and shfit the number ANY number of bits to the left, you'll get &hffffffff (-1 decimal).
To get true bits shift support, you'll need a C++ .DLL to take care of the bit shifting for you. This is because C++ can work on the numbers as unsigned, doing the shifting correctly, then sending them back to VB6. Even then, you won't be able to do reliable calculations with those numbers because the sign bit will not be valid. You may think you have a positive value after a bit shift operation when you don't.

Is it perfectly safe to keep adding and removing handlers using AddHandler and RemoveHandler?

Sure. Just make sure your not removing the handlers while they are still being used and remember to remove the handlers you don't need anymore.

Ive deployed a VB.APP using these[^] guidelines. The deployed version seems to have rearranged my controls on my form. Ive tried setting diffrent form attributes but nothing seems to work. The form looks fine in when I run the app from Visual Studio. See an image of the two forms here[^]. Also Id like to deploy the proper icon like the one shown on the left side. Thanks for any help.
I can post code if necessary.

HI I am new to the VB.net world, I am actually a student having a tough time with an assignment. The assignment wants me to make a software company. They sell three packages. Package A 99.00, Package B 199.00, PackageC 299.00. For buying a certain amount of quantity you get a discount.
Quantity discount
10 through 19 20%
20 through 49 30%
50 through 99 40%
100 or more 50%
With this I am suppose to have two messageboxes, one showing the amount of orders and one showing the grand total. With the grand total one I am supose to have a check box. Im really quite confused and ANY help that ANY one can give me I would be great appreciative! I have been working non stop on this and I dont' think I have made much progress.
Thanks!

Are you sure you're suppose to have message boxes? Or do you mean dialogs? or Text boxes on a dialog?

That is a bit vague. Can you narrow it down to something more specific?

So, what have to managed to get working so far, and what is still broken? Why not take the broken bits and work on them one at a time (if you are still stuck then you can ask here again with specific details on the bit you are stuck on)
If you take the problem and work on it bit by bit then it does make thinking about it a lot easier and less daunting. An easy thing to do is to make a list of everything still to do/get working and go through it.
I hope this helps, and just let us know if there is any particular part you need help on.

I can't seem to get the if/then/elseif to work on the %'s. the messagebox when I try to put in the controlchars.CrLf will not work. Pretty much everything. I try to write a line for the multiplication of the %'s and I am getting no where. Does that help?
|
|
|
|

The if/then/else part first:
' At some point in the code quantity is defined some how
' For example:
Dim quantity As Integer
quantity = 20
' The code will have to work out the discount.
' For example:
Dim discount As Double
discount = 0.0
If quantity >= 10 And quantity <= 19 Then
discount = 0.2
ElseIf quantity >= 20 And quantity <= 49 Then
discount = 0.3
ElseIf quantity >= 50 And quantity <= 99 Then
discount = 0.4
ElseIf quantity >= 100 Then
discount = 0.5
End If
Now, as for the multi line message box, you need to make sure the newline is defined properly. For example:
MessageBox.Show("My Multiline" + Environment.NewLine + "message!")
Environment.Newline is will always return the correct newline for the system. (Although I've not used it, I thing that if you were using the Mono framework [the open source version of the Class Runtime Library] on Linux it would just have the linefeed character, whereas on Windows it will have the linefeed and carriage return)
Does this help?

One more question:
When I go to my design and want to write the code for btncalculate, so that it will pull a messagebox with the totals, what code would I write for it to take Packagea (99.00) and the txtpackagea (insert amount here) to realize the % and come up with the correct total? Does that make sense?

KristineB wrote:

Maybe... I'll explain my assumptions because I am not 100% sure what you mean.
* You have a variable called Packagea which has a value of 99.00.
* You have a variable called txtpackagea which is a reference to the TextBox control
* You need to convert the text in the TextBox to a number in order to perform the calculation.
Try this:
Dim quantity As Integer
Try
quantity = Convert.ToInt32(txtpackagea.Text)
Catch ex As Exception
MessageBox.Show("The quantity entered for Package A is not a number")
End Try
Does this help?

Anyone here know if it would be possible to override the mouse click event when clicking on a POINT on a graph?
Basically, what I'm trying to do is, if the user clicks on a POINT on a graph, it will prompt him to enter comments on that particular point.
At the moment, if you double click on the graph, it will automatically open the edit chart dialog.
Anyways, if anyone can share some insight on the problem at hand, let me know.
Thanks,
Jon

You'd have to write code to map the mouse click onto the image of the chart and then determine if the mouse click actually hit the POINT on the graph. But, that would require your code knowing exactly where each point was in the chart image. As far as I can tell, there is no way of determining that...

You should use Install Shield to create package. Its very good and supply functions to create key option
Good luck

Hi,
I'm trying to create a little service that connect to a SQL database.
I'm using USER ID and password for authentication and everytime I try to open the connection I receive the following error :
System.Security.SecurityException: Échec de la demande pour une autorisation de

cObjConn.Open()<br />
<br />
Catch se As System.Security.SecurityException<br />
System.Console.Out.Write(se.ToString)<br />
End Try<br />
Does any1 know where I'm wrong ?

Try dropping the "Trusted Connection" portion of your connection string. Also, make sure that the UserName and Password is setup correctly in the SQL Manager so that the ID has the correct rights to the database it's supposed to.

back from holiday....
The problem is not in that way. I've heard something about a policy that you have to create to establish a trust connection between the client and the server when there aren't running on the same computer.

|

It's not so much a policy ... I think this[^] is what your referring to...

Your right but I've heard about a method to use with application.
I've got about 500 Pc and I don't want to add all one by one on my windows 2000 Server which is not an Active Dir.

In that case, you can't use a trusted connection. Since all of your machines are not in the same domain, you can't use the same username/password (or SID) for each user that accesses your SQL server. A better method to use, in your case, would be SQL authentication using an SQL user ID and password that is specific to the database you want. This actualy offers you better security because the SQL user ID doesn't have any rights to any other part of the server that is hosting your SQL server. This means that the ID can't be used to open any shares on that box, or anything else for that matter, just the database, tables, views, stored procedures, ... that you specify in the SQL Enterprise Manager.
