I'm not sure if I understand what you want here.
Do you want several images reduced in size at one side of your PictureBox? Like say the bottom, kind of like Microsoft Explorer's Film Strip mode?
If so, then there is no "magic" function to render this for you. You're going to need to handle the PictureBox's Paint event and draw these clips there yourself via GDI+. Have a look at the System.Drawing namespace.

Hello!
My aim is to get command line arguments inside the code. Would you please show me the statement for the purpose. How can I get multiple arguments that are passed via executable program name. eg( abc.exe c:\def.jpg)
Thanks.
|
|
|
|

The easiest way to do this is to change your project's Startup Object from your form to "Sub Main". You can get the command line arguments from there as follows.
Public Class Main
Public Shared Sub Main(ByVal args() As String)
Application.EnableVisualStyles()
Application.DoEvents()
Application.Run(New MyForm)
End Sub
End Class
An alternative to this is to call System.Environment.CommandLine. The difference here is that it gives you the whole command line as one string and you have to parse it yourself.

Hello!
It is not possible to hide or disable a tabcontrol's tabpage in VS .NET 2005. If anyone of you a way to hide or disable the tabpage please let me know or feel free to suggest me an alternative solution for the problem.
Thanks!
|
|

Removing the TabPage from the TabControl's collection effectively hides it. You can reshow it by Adding it back into the collection again.
MyTabControl.TabPages.Remove(MyTabPage)
|
|
|
|
|
I think it is wrong! When you remove a tabpage from the collection. It removes everything in the tabpage, you won't able to put them back. When you add it to collection later, it shows an empty tab page...
|
|
|
|
|
You need to Remove the TabPage in your code to make this work, not through the form editor.
First create the TabPage in your form editor like you did before.
Next, in your form code you would Remove the TabPage from the TabControl's TabPage collection like this.
myTabControl.TabPages.Remove(myTabPage)
Trust me, this works. You can re-add the page to the TabControl like this.
myTabControl.TabPages.Add(myTabPage)

I'm using the following VB.Net code to retreive the field names of a table in an Access db:
Dim NewField As ADOX.Column
Dim tblField As ADOX.Column
For Each tblField In adocat.Tables("tblData").Columns
The fields are returned in alphabetical order! I want to have the fields returned in the order they were created. Can this be done?

There is no escape from the loop, so it surely will hang your program. You have to add a condition for when the loop should end.

b { font-weight: normal; }

thanks, but now i have another error on the path which value cannot be null.When i havent put into the loop it works.. but after put it in.. it said the path is null.. any idea wat happen to it?
For x = 1 To Val(ComboBox1.Text)
'to compare the other player,no need compare to itself
' y = pi(c).Text 'current player selection
i = pi(x).Text 'other player selection
If c <> x Then
If y = i Then
Do
'Randomly pick number from 1 to 7
Randomize(bc)
y = (Int(Rnd() * 7) + 1)
pi(c).Text = y
tokenform.token.Text = y
If y = 1 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\1egg.gif")
ElseIf y = 2 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\2egg.gif")
ElseIf y = 3 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\3egg.gif")
ElseIf y = 4 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\4egg.gif")
ElseIf y = 5 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\5egg.gif")
ElseIf y = 6 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\6egg.gif")
ElseIf y = 7 Then
imagetoken = (Path.GetDirectoryName(Application.ExecutablePath) & "\tokenimage\7egg.gif")
End If
Loop Until y <> i
End If
End If
Next

That is because you only set the path if you had to pick a random number.

b { font-weight: normal; }

actually i was trying to make the image keep on changing so it loop like randomly chossing picture.... i try to move that if..else statement after the loop but same error...
|
|
|
|
|
What does the code look like where you get the error, then?

First, you need to read up on ADO.NET[^]. It's important for you to know how to use this library's classes before you can continue.
You'll need to use the OleDB classes to connect to an Access database.

Module Modtest<br />
Public dparmor As New dpGenerals<br />
Public Sub Test()<br />
dparmor.Add(4, "light", "armor")<br />
dparmor.Add(2, "heavy", "armor")<br />
<br />
dparmor.Section.Addbla(1, "SUB!1", "armobSuB")<br />
'dparmor.Add.Addbla(1, "SUB!1", "armobSuB")<br />
<br />
MsgBox(dparmor.Section(0).key)<br />
End Sub<br />
End Module<br />
All i am trying to do is have a few nested collections :/.
Aparmor.add() allows me to add a section
but for the life of me i cant get the addbla() to add a sub section.
I would like many levels deep dparmor.section(0).section(0).section(0).key
i would also like many levels of keys
ie dparmor.section(0).keys(0).key
dparmor.section(0).section(0).key
Please i know its probably so simple but i just cant figure it out, i do know that sections is the collection of a type section and that the addbla is under sections and not section. but i dont know how to go about fixing this. As you can see there are a few more properites but i think if i can just get that part working the rest will fall into place.
Please any help with this is greatly appreciated.
Thanks

You are adding everyting into the same list, and you don't even create that list anywhere, you just use it out of the blue...

b { font-weight: normal; }

i didnt think i needed to add that code as well
Public dparmor As new dpGenerals
will thats the line there ... then ie
dparmor.section(0).keys(0).key<br />
dparmor.section(0).section(0).key<br />
dparmor.section(0).section(0).section(0).key
but i cant get the add to work as mentioned above, the adding of a section works cus it Class dpGenerals (add). But the property dpGenerals.Section is a collection of the type section, so i cant call the dparmor.section.addbla(). I just dont know how to convert the code to be able to call that fucntion addbla. I dunno if that makes it any clearer ?

i just figured it out ... made 2 changes and works now :/

But you did show that code already, but that's not the collection you are adding the values to. I'm talking about the collection named List that you are using in the code.

recently i posted a question as follows
---------------------------------------
i am using toolbar component .net ver 2 (not toolstrip) in vb.net 2005.
if i give application.enablevisualstyle command to enable xp style interface
then icons on my toolbar will not come. if i disabel xp visual style it will
come? how can i show this toolbar in xp style settings?
pls help me....
This is the answer which i got
------------------------------
This is a bug in the .NET framework. You can work-around it by calling
Application.DoEvents() after EnableVisualStyles.
i tried this, but its not working,
after this also i can't see toolbar icons, i can see
only deviders, can u please explain me to solve this
problem...
with thanks

You should enable visual styles in a Main function, before your form gets loaded, then call DoEvents(). I recommend that you create a Main class and add the Main method there as shown below.
Public Class Main
Public Shared Sub Main(ByVal args() As String)
Application.EnableVisualStyles()
Application.DoEvents()
Application.Run(New MyForm)
End Sub
End Class
Next, you need to change your project setting's Startup Object to "Sub Main". You can find this option by right clicking your project in the solution explorer, click on Properties, select CommonProperties\General in the dialog's tree.
