What happens if you just do a port ping from your machine to the SMTP server on port 25?
|
|
|
|
|
I finally got to the bottom of my problem.
I have McAfee AV Enterprise v8.5 installed, which has a section within it called "Access Protection". Within this section you can define rules such as block all programs sending data via Port 25. I had not included my program into the exceptions list.
So you where close when said to check out my firewalls.
Thanks

I want to disable the visual styles for a usercontrol (I draw the whole thing myself (or almost))
but I can't seem to find how to do this
I know how to enable it : EnableVisualStyles
but how do you disable it?
I use visual studio 2005
also (just in case disable doesn't work) how can I tell my control to use a specifiek theme (silver for instance)
|
|
|
|
|
Hi, I dont know for VisualStyles in particular but there is a Control.SetStyle() method
that lets you exlain the control will be owner-drawn. Hope this helps.
|
|
|
|
|
I already did that
Me.SetStyle(ControlStyles.UserPaint, True)
but the control still seems to take the windows colors for the area's that I don't redraw
|
|
|
|
|
To get double-buffering in .NET 1.1 I used to set three bits: DoubleBuffer, AllPaintingInWmPaint, and UserPaint.
I expect you need to set the last two.
|
|
|
|
|
the problem is solved (at least for a bit)
he doesn't seem to use the theme's anymore but the controls does change the shade of white he uses from pc to pc
no clue why but at least ist a shade of white now
thanks

Hi, Concerning declarations of variables
Could some one please help by filling in the blanks to explain what I can't seem to find in my various VB.Net Library?
Dim:- Can be used to declare variables within the entire Form if placed before all the Private Sub crap, other wise known as the General Declarations area. Otherwise is for Local Variables only.
Static:- When used with a Local variable, the value is preserved for the lifetime of the application (while the program is running).
Public:- Must be contained in a standard Module not a Form and are visible throughout the entire project. (A Module is a Form without a user interface.)
Protected:- (Your answer goes here )
Friend:- Access is similar to Public, only Friend is restricted to only code within it’s project (application).
Shared:- (Your answer goes here )
Protected Friend:- (Your answer goes here )
Private:- Appears to be the same as Dim. Is it? (Your answer goes here )
Thank You!

Dim just declares a variable, the rest of what you said is about what the scope (visibility) of that variable is. A class wide variable is called a member variable.
frankiebaby2 wrote: Static:- When used with a Local variable, the value is preserved for the lifetime of the application (while the program is running).
Static means only one instace of a variable exists, so if it's a member, it's the same value for all instances, if it's inside a class, I believe it will persist, although it will get set every time it's called, unless there's a conditional branch.
frankiebaby2 wrote: Public:- Must be contained in a standard Module not a Form and are visible throughout the entire project. (A Module is a Form without a user interface
Wrong - a form can contain a public variable, although you should never use public variables anywhere ( use properties to expose private/protected variables )
Protected - means a variable is visible only to classes derived from this one
friend - this must be the same as 'internal' in C#. Man, VB naming is gay.
shared - is static ( static is a C# keyword, shared is it's VB equivelant )
protected friend - means it's visible only to classes derived from this one, and within the assembly
private - means only visible inside the class. private is the default, so if you don't specify anything, dim will assume private.
BTW, you could trivially have found all this out with google.

Is that VB specific terminology ?

Thank you Christian,
I appreciate you patience, Have tried Googling many things first but get overloaded with info and have trouble with info burn-out.
The manuals for VB.NET never seem to lay out the data completely. They touch on things and run off in all directions never completing all the info on the topic so that I can fully grasp it.
Once again,
Many Thanks Mate!

Dim declares variables and specifies their types and a possible initialization values.
frankiebaby2 wrote: Static:- When used with a Local variable, the value is preserved for the lifetime of the application (while the program is running).
Declares a variable as "persistant" between calls. For example, if you have a sub that is called many times and a variable in it is declared static, it retains it's value between calls. The variable is not destroyed and recreated to an intialized value. This can only be used at the procedure level.
frankiebaby2 wrote: Public:- Must be contained in a standard Module not a Form and are visible throughout the entire project. (A Module is a Form without a user interface.)
Specifies that a variable is visible outside the scope it is declared in. Public can only be specified at the namespace, module, or file level. Specifying Dim is optional.
frankiebaby2 wrote: Protected:- (Your answer goes here )
Protected variables or procedures are only visible to the class they are declared in or in derived classes.
frankiebaby2 wrote: Friend:- Access is similar to Public, only Friend is restricted to only code within it’s project (application).
Friend means that the element is only visible to code inside the same assembly (.DLL, .EXE) as the Friend element.
frankiebaby2 wrote: Shared:- (Your answer goes here )
Only a single instance of the Shared element exists and it exists without an instance of the class it's declared in.
frankiebaby2 wrote: Protected Friend:- (Your answer goes here )
A combination of the two above.
frankiebaby2 wrote: Private:- Appears to be the same as Dim. Is it? (Your answer goes here )
Declares the element is not visible outside the scope it is declared in. For instance, Private members of a class are only visible inside the class and any code in it. It is NOT a replacement for Dim.
The complete variable declaration line looks like this:
[ <attributelist> ] [ accessmodifier ] [[ Shared ] [ Shadows ] | [ Static ]] [ ReadOnly ]
Dim [ WithEvents ] variablelist
You do not have to have an attributelist.
You do not have to specify an access modifer, Public, Private, Protected, Friend, Protected Friend. If not access modifier is specified, Private is assumed.
Everything I just wrote, came from here[^].

Thanks Dave,
I am glad there are people like youself who can take the time to explain these things to inexperienced people such as myself.
A programmer I will never be, but if I am close to having enough education to write a program that will give me more time to spend with my family.

can someone help me about making the codes for a game...similar to the "star of david"
|

What is 'star of david' ?
Obviously, no-one is going to answer this, because the question is too broad. The best we can do, is give a broad reply. You want to install DirectX if you want to write anything but the most trivial of turn based games. It comes with plenty of examples you can work through. If your game is simple and turn based, then you should be fine using just GDI+.
Either way, make sure you know VB well before you embark on a game project, games are amongst the most complex things you can try to write.

Your request is too vague. You need to be specific. Even a game as simple as noughts-and-crosses (tic-tac-toe in some parts of the world) would be too much to answer for a forum post.
You should start by planning your game. What are the rules? What do you need to display on the screen? Is it a single player game, or multi-player? Will you compete against the PC or a player across the internet?

A lot of your posts are obvious homework questions. If you are not willing to do the work yourself, drop out of school now.

Hi
i am working in VB.net using .net 2.0. i have a requirment to disable a listbox control's single item ....i searched msdn which says..
"You can disable an item in a list box or combo box by adding a single backslash to the beginning of the expression. "
i tied the following code
ListBox1.Items.Add("good")
ListBox1.Items.Add("\bad")
but it didn't worked and "bad" did not appeared disabled..
dispite this my requirement is to disable an item when mouse double click event occurs...
hope someone will come with solution
Faith is higher faculty than reason..

A listbox contains listitems. The listitem object has an enabled property on it. Find the correct listitem and mark the enabled property to false. There is a double click event on the listbox. The sender passed it should be the listbox. You should be able to cast the sender as a listbox and get the selectedindex. Use the selected index to get the listitem and set the enabled = false.
Hope that helps.

but its not possible because there is no class in whichi save that item further there wasn't any need to use selectedindex for selecting item but i can use selecteditem for such purpose..
so the origanl question is as it is...
May God help u solv ur problems as well,thx in advance!!

So using SelectedItem would work fine too.
inside the method you would have:
DirectCast(Sender, ListBox).SelectedItem.Enable = false
Pretty sure that should work.

no its not working at all.. i did just as mentioned..it gives this exception message
"Public member 'Enable' on type 'String' not found."
its windows application i hope you are not misinterpretting that its web application.
May God help u solv ur problems as well,thx in advance!!
